Specifically, the shape of the measuring container 10 in the present embodiment may be various, for example: the measuring container 10 may be in a regular shape such as a cylindrical shape, a prismatic shape, an ellipsoidal shape, or the measuring container 10 may be in other irregular shapes as long as the measuring container 10 is ensured to have a closed containing cavity for containing the acid solution.

Preferably, the material of the measuring container 10 in this embodiment may be various, for example: the measuring vessel 10 may be mainly made of metal material such as copper, iron, aluminum, or the like, or the measuring vessel 10 may be mainly made of non-metal material such as plastic, ceramic, or the like.

Specifically, the positions of the inlet and the outlet on the measuring container 10 in this embodiment may be various, for example, the measuring container 10 is in a rectangular parallelepiped shape, the measuring container 10 has a bottom surface disposed parallel to the horizontal plane and facing the ground, the inlet and the outlet may be disposed on the side of the measuring container 10 perpendicular to the bottom surface, wherein the inlet and the outlet may be disposed on the same side, or the inlet and the outlet may be disposed on different sides of the measuring container 10, respectively, and preferably, the inlet and the outlet are disposed close to the bottom surface of the measuring container 10; of course, both the inlet and the outlet may be provided on the bottom surface of the measuring receptacle facing the ground.

The valve 301 can control the on-off of the second pipeline 30, so as to prevent a large amount of acid liquor from being discharged through the second pipeline 30 when the liquid pipeline 50 delivers the acid liquor, thereby causing waste of the acid liquor.

Preferably, the valve 301 may be a valve 301 such as a ball valve or a gate valve that needs to be manually operated, or the valve 301 may be an electrical valve that controls the electromagnetic valve to control the on/off of the second pipeline 30, and the operation is simple and fast.

Specifically, the mass detection device may be an electronic scale or other device capable of measuring the mass of the measuring container 10, which is disposed at the lower portion of the measuring container 10, and the mass detection device is placed on the ground or on a test bench, so that when acid liquid is input into the measuring container 10 through the first pipeline 20, and the containing cavity is filled with acid liquid, the mass detection device detects the total mass of the measuring container 10, and then the total mass is subtracted from the net mass when the measuring container 10 is not filled with acid liquid, so as to obtain the mass of the acid liquid in the measuring container 10.

Specifically, the pressure detection device may be a pressure gauge, and a detection end on the pressure gauge is communicated with the containing cavity in the measurement container 10, so as to read the pressure of the acid liquid in the measurement container 10 through a pointer of the pressure gauge.

The first pipe 20 is connected to a side wall of the liquid pipe 50 so that when the pressure source 501 such as a pump truck is operated, the acid liquid pressure in the liquid pipe 50 is increased, and the acid liquid in the liquid pipe 50 is introduced into the measuring container 10.

Specifically, one end of the second pipeline 30 is communicated with the outlet, and the other end of the second pipeline 30 can be communicated with the recovery tank 40, so that when the acid liquid in the measuring container 10 is discharged along the second pipeline 30 when the valve 301 is opened, the acid liquid can be recovered into the recovery tank 40, so as to prevent the acid liquid from being directly discharged into the environment, which results in waste of the acid liquid and pollution to the environment.

In particular, the first conduit 20 may be a rubber tube or other conduit having a certain flexibility, so as to prevent the first conduit 20 from affecting the detection of the quality of the measuring container 10; similarly, the second conduit 30 is a rubber tube or other flexible conduit.

The use process of the compression factor detection device in the embodiment is as follows: controlling a pump truck and other pressure sources 501 to convey acid liquor to the liquid pipeline 50, opening a valve 301, enabling the acid liquor in the liquid pipeline 50 to enter the measuring container 10 under the action of pressure, and when the measuring container 10 is filled with the acid liquor, acquiring that the mass of the acid liquor in the measuring container 10 is m through a mass detection device₁Meanwhile, the pressure p of the acid liquid in the measuring container 10 is obtained and measured through a pressure detection device₁(ii) a The delivery pressure of the pressure source 501 such as a pump truck is changed, so that the delivery pressure in the liquid pipeline 50 is changed, and the mass m of the acid liquid in the measuring container 10 is obtained by the mass detection device₂Meanwhile, the pressure p of the acid liquid in the measuring container 10 is obtained and measured through a pressure detection device₂. The acid liquid has a compression coefficient of

Where d ρ is ρ₁-ρ₂Wherein, in the step (A),v is the volume of the measuring container 10, and dp is p₁-p₂、

To sum up:finally, the compression coefficient of the acid liquid is obtained. The volume of acid liquid delivered by the pressure source 501 such as a pump truck is appropriately increased according to the calculated compression coefficient, so that the situation that the internal acid liquid of the pipe column 502 is insufficient after the acid liquid at the bottom of the pipe column 502 is compressed is avoided.

The compressibility detection device provided in this embodiment is configured to communicate an inlet of the measurement container 10 with the liquid pipeline 50 through the first pipeline 20, communicate an outlet of the measurement container 10 with one end of the second pipeline 30, and provide the valve 301 on the second pipeline 30, wherein the quality detection device is configured to detect the mass of the measurement container 10, the pressure detection device is configured to detect the pressure of the acid liquid in the measurement container 10, and change the pressure of the acid liquid in the liquid pipeline 50, so that the quality detection device detects the mass of the measurement container 10, and the pressure detection device detects the pressure of the acid liquid in the measurement container 10, thereby calculating the compressibility of the acid liquid; the volume of the acid liquid output by the pressure source 501 is properly increased according to the compression coefficient, so that the insufficient acid liquid caused by the volume reduction of the acid liquid at the bottom of the pipe column 502 after compression is avoided.

With continued reference to fig. 2. Specifically, the compression coefficient detection device further comprises a controller 103 and a display 104, the quality detection device is a weight sensor 101, and the pressure detection device is a pressure sensor 102; the controller 103 is electrically connected to the display 104, the weight sensor 101 and the pressure sensor 102, and the display 104 is used for displaying and measuring the mass and the pressure of the acid liquid in the container 10. The display 104 can directly read and measure the mass and pressure of the acid liquid in the container 10, so that the data can be conveniently obtained; in addition, the display 104 can display the pressure and the mass of the acid liquid in the measuring container 10 in real time, and can calculate the compression coefficient of the acid liquid in real time.

Specifically, the controller 103 may be a single chip microcomputer, a programmable logic controller, a personal computer, or the like, and further, by setting a program in the controller 103, the controller 103 may directly calculate a compression coefficient of the acid solution according to data detected twice by the pressure sensor 102 and the weight sensor 101, and display the compression coefficient on the display 104, so as to avoid manual calculation.

Continuing with reference to fig. 1, 3-6. Specifically, the valve 301 is a pressure regulating valve for regulating the pressure of the acid liquid in the measuring container 10. The volume of the acid liquid in the measuring container 10 can be adjusted by the pressure regulating valve, and the pressure of the acid liquid output by the pressure source 501 can be kept constant.

The compression coefficient detection device provided by the embodiment is used as follows: controlling a pump truck equal-pressure source 501 to convey acid liquid to the liquid pipeline 50, adjusting the pressure regulating valve to enable the opening pressure of the pressure regulating valve to be a first preset pressure, enabling the acid liquid in the liquid pipeline 50 to enter the measuring container 10 under the action of the pressure, and when the measuring container 10 is filled with the acid liquid, acquiring the mass m of the acid liquid in the measuring container 10 through the weight sensor 101₁Meanwhile, the pressure of the acid liquid in the measuring container 10 is obtained and measured as p through the pressure sensor 102₁And inputs the acquired data to the controller 103; the pressure regulating valve is adjusted again to make the opening pressure of the pressure regulating valve be the second preset pressure, and the weight sensor 101 obtains the mass m of the acid liquid in the measuring container 10₂Meanwhile, the pressure of the acid liquid in the measuring container 10 is obtained and measured as p through the pressure sensor 102₂And transmits the data to the controller 103. The controller performs the following calculations based on the acquired data:

the resulting compressibility of the acid is displayed on the display 104. It should be noted that the first preset pressure and the second preset pressure should both be smaller than the pressure of the acid liquid output by the pressure source 501, so as to ensure that the pressure regulating valve can be normally opened under both the first preset pressure and the second preset pressure. Finally, the volume of the acid liquid delivered by the pressure source 501 such as a pump truck is appropriately increased according to the calculated compression coefficient, so that the shortage of the acid liquid in the pipe column 502 due to the fact that the acid liquid at the bottom of the pipe column 502 is compressed is avoided.

With continued reference to fig. 3. Specifically, the first conduit 20 is connected to the inlet by a first buffer tube 201, the first buffer tube 201 being helical. The first buffer tube 201 having a spiral shape can prevent the first pipe 20 from interfering with the quality detection device, thereby enhancing the accuracy of the quality of the measurement container 10 detected by the quality detection device, and further improving the accuracy of the compressibility detection device.

Preferably, one end of the first pipe 20 facing the inlet is spirally wound around a first central line to form a first buffer tube 201, the central line of the first buffer tube 201 is arranged parallel to the horizontal plane, and the first buffer tube 201 and the first pipe 20 are made of materials with certain flexibility, such as rubber, and the like; or the first pipeline 20 is a pipe made of rigid materials such as a metal pipe and a plastic pipe, and at this time, the first buffer pipe 201 is a spiral pipe made of materials with certain flexibility such as rubber, so that the strength of the first pipeline 20 is ensured, and the influence of the first pipeline 20 on the quality detection device is also avoided.

With continued reference to fig. 4. Specifically, the second conduit 30 is connected to the outlet by a second buffer tube 302, the second buffer tube 302 being helical. The second helical buffer tube 302 prevents the second tube 30 from interfering with the quality detection device, thereby enhancing the accuracy of the quality of the measurement container 10 detected by the quality detection device and improving the accuracy of the compressibility detection device.

Preferably, one end of the second pipe 30 facing the outlet is spirally wound around a second central line to form a second buffer tube 302, the central line of the second buffer tube 302 is arranged parallel to the horizontal plane, and at this time, the second buffer tube 302 and the second pipe 30 are made of the same material, which may be rubber or other material with certain flexibility; or the second pipeline 30 is a pipe made of rigid materials such as a metal pipe and a plastic pipe, and the second buffer pipe 302 is a spiral pipe made of materials with certain flexibility such as rubber, so that the strength of the second pipeline 30 is ensured, and the influence of the second pipeline 30 on the quality detection device is avoided.

Specifically, the first center line and the second center line are both disposed perpendicular to the horizontal plane, so as to further reduce the influence of the first buffer tube 201 and the second buffer tube 302 on the quality detection device, and further improve the accuracy of the compressibility detection device.

With continued reference to fig. 5. Specifically, the compressibility detection device further includes a protective cover 60, and the protective cover 60 is covered on the outside of the measurement vessel 10. The protective cover 60 can prevent an external object from contacting the measuring container 10, thereby affecting the quality of the measuring container 10 detected by the quality detecting device.

Preferably, the protective cover 60 may be a metal cover mainly made of a metal material such as copper, iron, or aluminum, or the protective cover 60 may be a non-metal cover mainly made of a non-metal material such as plastic, rubber, or ceramic.

It is further preferred that the protective cover 60 is a transparent cover so that the operating state of the measuring vessel 10 can be observed through the protective cover 60. Specifically, the protective cover 60 may be composed mainly of transparent plastic, rubber, glass, or the like.

Specifically, the other end of the second conduit 30 communicates with the tubing string 502. So as to discharge the acid liquid in the measuring container 10 into the pipe column 502, thereby avoiding waste of the acid liquid.

Preferably, the second conduit 30 may be in direct communication with the tubing string 502, or the second conduit 30 may be in indirect communication with the tubing string 502.

With continued reference to fig. 6. Specifically, the second conduit 30 is in communication with the tubing string 502 via the fluid conduit 50, and the connection between the first conduit 20 and the acid fluid pipe is located closer to the pressure source 501 of the acid fluid pipe than the connection between the second conduit 30 and the acid fluid pipe. When the pressure source 501 works, acid liquor in the liquid pipeline 50 enters the measuring container 10 through the first pipeline 20, and after the container 10 to be measured is filled with the acid liquor, the acid liquor flows back to the liquid pipeline 50 through the second pipeline 30; in addition, the second conduit 30 is indirectly in communication with the tubing string 502 via the fluid conduit 50, which may reduce the length of the second conduit 30.

Specifically, the outlet is provided at the top of the measuring container 10, and the inlet is provided on the side wall of the measuring container 10 near the bottom. So as to ensure that the acid liquid in the measuring container 10 flows out through the outlet and the second pipeline 30 after the measuring container 10 is filled with the acid liquid, thereby preventing the insufficient precision of the compression coefficient detection device caused by the insufficient acid liquid in the measuring container 10.
