Detailed Description

The embodiment of the application provides a full-automatic measuring device, and solves the technical problem that in the prior art, the cooling uniformity in the width direction of the hot-rolled strip steel after being rolled is inconvenient to detect.

In order to solve the technical problems, the general idea of the embodiment of the application is as follows:

a full-automatic measuring device is matched with a laminar flow cooling collecting pipe, the laminar flow cooling collecting pipe comprises a plurality of nozzles which are arranged in a row, the full-automatic measuring device comprises a water quantity collecting box, an automatic drainage mechanism, a floating ball liquid level meter and a control system, the water quantity collecting box is provided with a water inlet and a water outlet, the water inlet is arranged corresponding to at least one nozzle, the opening cross-sectional area of the water outlet is larger than the sum of the opening cross-sectional areas of all the nozzles corresponding to the water inlet, the automatic drainage mechanism is internally provided with a water quantity collecting box and is installed at a drainage port, the automatic drainage mechanism is provided with a drainage trigger point and a drainage stopping point, the floating ball liquid level meter is vertically installed in the water quantity collecting box and comprises at least two floating balls arranged between the drainage trigger point and the drainage stopping point, and the control system is used for obtaining the time consumed by the liquid level in the water quantity collecting box from one floating ball to the other floating ball.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

Example 1

The embodiment provides a fully automatic measuring device 10, which comprises a water quantity collecting box 100, an automatic drainage mechanism 200, a floating ball liquid level meter 300 and a control system 400.

The inventor finds that the cooling uniformity in the width direction of the hot rolled strip in the cooling process after rolling is an important factor influencing the strip shape quality, and in the related art, as many as dozens of small U-shaped nozzles 21 are uniformly arranged in each header in the width direction of the rolling line, and the flow of dozens of nozzles 21 in each laminar flow cooling header 20 in the width direction of the rolling line needs to be ensured to be consistent from the uniformity consideration. However, because the nozzles 21 at different positions are affected by factors such as corrosion and blockage, and a precise flow measuring device for the small nozzles 21 is lacked, the laminar flow equipment is difficult to maintain, and the frequent plate shape quality problem is caused.

The inventor of the present invention has found through research that if the measurement method of the flow meter is directly adopted, the flow meter cannot be normally installed near the nozzle 21 of the laminar cooling header 20 because the straight pipe section is short, the specification of the flow meter is not compatible with the small flow meter because the space is narrow and the pipe section is thin, and the flow meter is too much because the number of the nozzles 21 is large.

The inventor therefore provides a fully automatic measuring device 10 comprising a water collection box 100, an automatic drainage mechanism 200, a float level gauge 300 and a control system 400.

The water collection box 100 is provided with a water inlet 110 and a water outlet 120, as shown in fig. 2, the water inlet 110 is provided at the upper end of the water collection box 100, the water outlet 120 is provided at the lower end, wherein the water inlet 110 is provided corresponding to at least one nozzle 21 of the laminar flow cooling header 20, and the water outlet is provided with an automatic water discharge mechanism 200.

The automatic drain mechanism 200 is installed at the drain opening 120, and as shown in fig. 2, the automatic drain mechanism 200 is installed in the drain opening 120. The automatic drainage mechanism 200 is provided with a drainage trigger point 210 and a drainage stop point 220, when the liquid level in the water collection box 100 rises to the drainage trigger point 210, the liquid in the water collection box 100 is automatically drained from the drainage outlet 120 through the automatic drainage mechanism 200; when the liquid level in the water collection box 100 continuously drops to the water stop and drain point 220, the automatic drain mechanism 200 stops working, and the liquid level in the water collection box 100 rises again when the nozzle 21 is filled with water.

For example, as shown in fig. 2, a water dropping bladder is used as the automatic drainage mechanism 200, and the water dropping bladder has the advantages of simple structure, convenient purchase, convenient installation and the like. Specifically, the water collecting box 100 is disposed in the water tank, the water tank is installed at the water outlet 120, the water tank includes a U-shaped tube, the U-shaped tube has a water outlet, and the water outlet is communicated with the water outlet 120. The other pipe orifice of the U-shaped pipe, which is different from the water outlet, is communicated with the chamber of the water collection box 100 and is higher than the water outlet, so as to achieve the preparation condition of siphon effect. When the liquid level in the box reaches the drainage trigger point 210 shown in fig. 2, i.e. the U-bottom position of the U-shaped pipe in fig. 2, the water falling bladder siphons to drain the water in the box from the drainage outlet 120.

More, the automatic drainage mechanism 200 may also adopt other arrangements, for example, adopt a full-automatic arrangement, arrange sensors at corresponding positions, introduce more complicated signal collection systems and control methods.

The full-automatic measuring device 10 of this embodiment is further provided with a floating ball liquid level meter 300, and several points are selected for detecting the rising process of the liquid level in the box. As shown in fig. 2, the two floating balls 310 are disposed between the level of the drain trigger point 210 and the level of the stop drain point 220, so that two floating ball trigger signals can be outputted during the rise of the liquid level in the cartridge.

The control system 400 is used to obtain the time spent by the liquid level in the water collection box 100 from one floating ball 310 to another floating ball 310, and accordingly, the control system 400 can record the time point data when receiving the triggering signal of the floating ball 310. In obtaining the total flow rate of the nozzles 21 corresponding to the water inlet 110 of the water collecting box 100 by using the formula of dividing the volume by the time equal to the flow rate, the volume data, i.e. the partial volume of the water collecting box 100 between the height ranges of the two floating balls 310, is also needed, and the volume data can be determined before the detection.

For example, the water amount collecting box 100 may be provided in a long strip shape or a cylindrical shape, and the volume of the cylindrical body can be easily calculated. Alternatively, as shown in FIG. 2, the inlet 110 is square and the outlet 120 is circular, facilitating access to volumetric data and larger cross-sectional areas of the outlet 120.

It should be noted that, in the process of measuring flow data by using the full-automatic multiple measurement of the present embodiment, it is necessary to ensure that the discharge flow rate is greater than the injection flow rate of the nozzles 21 during the water discharge, so that the opening cross-sectional area of the water discharge opening 120 is defined to be greater than the sum of the opening cross-sectional areas of all the nozzles 21 corresponding to the water inlet 110.

More, the float level gauge 300 can also be provided with three, four or more floats 310 between the drainage trigger point 210 and the stop drainage point 220, so as to obtain more float trigger signals in one rising process of the liquid level, obtain more available data and provide powerful data support for maintenance of laminar flow cooling equipment.

The water quantity collecting box 100 is fixedly installed on the main pipe body 22, the water quantity collecting box 100 is installed below the nozzle 21, and the water inlet 110 is arranged opposite to the nozzle 21. The water inlet 110 is arranged corresponding to at least one nozzle 21, the number of the nozzles 21 is related to the spatial distribution of the nozzles 21 and the area of the water inlet 110, more choices can be made for the number, that is, total flow data of a plurality of nozzles 21 can be obtained through a single full-automatic measuring device 10, and whether the nozzles 21 work normally or not is judged through data comparison and analysis, so that the detection of the nozzles 21 with various numbers is facilitated, and the spatial arrangement of the water collection box 100 when being installed on the main pipe body 22 is also facilitated.

In the setting that the water collection box 100 is installed below the nozzle 21 of the laminar flow cooling header 20, the fully automatic measuring device 10 may alternatively be configured with another support frame below the nozzle 21, or as shown in fig. 1, the water collection box 100 is fixedly installed on the main pipe 22 of the laminar flow cooling header 20, so that the water inlet 110 faces the nozzle 21.

Alternatively, in order to facilitate the installation and the detachment of the water collection box 100 to the main pipe body 22, a transverse restraining straight rod 140 may be fixedly installed on the peripheral wall of the main pipe body 22, the transverse restraining straight rod 140 having one end close to the main pipe body 22 and one end far from the main pipe body 22, wherein the former has a lower height than the latter. As shown in fig. 1, the opposite vertical walls of the water collecting chamber 100 are provided with stopper holes 130. When the water collection box 100 is installed, the limiting hole 130 is aligned with the transverse limiting straight rod 140 and penetrates through the limiting hole.

In more installation modes, detachable modes such as threaded connection and the like can be adopted.

Alternatively, referring to fig. 3 and 4, the water collection box 100 may be installed in a hanging manner, compared to the above-described installation manner by the transverse limiting straight rod 140. Specifically, the water collection box 100 is fixedly provided with at least one pair of suspension brackets 150, the pair of suspension brackets 150 comprises two suspension rods 151 which are symmetrically arranged, the suspension rods 151 are fixedly installed on the water collection box 100, the suspension rods 151 are provided with suspension holes 152, the laminar flow cooling header 20 further comprises a main pipe body 22 and a nozzle positioning frame 23, the nozzle positioning frame 23 and the main pipe body 22 are arranged side by side at intervals, the plurality of nozzles 21 are arranged in the main pipe body 22 in a row, and the nozzles 21 are all arranged on the nozzle positioning frame 23 in a penetrating manner. The suspension bracket 150 is provided with a limiting rod 160, when the installation is completed, the limiting rod 160 penetrates through the suspension holes 152 of the two suspension rods 151 of the suspension bracket, the two suspension rods 151 of the suspension bracket 150 are respectively arranged at two sides of the nozzle positioning bracket 23, and the limiting rod 160 abuts against the upper side face of the nozzle positioning bracket 23.

As shown in fig. 3 and 4, the water collection box 100 is mounted to the nozzle positioning frame 23 through two pairs of left and right suspension frames 150, which can directly use the nozzle positioning frame 23 without tapping or welding on the structure of the laminar flow cooling header 20, and can be mounted conveniently by using a suspension method without reworking the laminar flow cooling header 20. It will be appreciated that the water collection cartridge 100 may be mounted in a hanging manner by one, two or even more pairs of hangers 150.

Alternatively, the water collecting box 100 may be made of a metal material, such as aluminum or iron, or a non-metal material.
