Detailed Description

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.

As shown in fig. 1, an embodiment of the present invention provides a water quality monitoring and filtering apparatus, including: the device comprises a water inlet pipe 1, a sand setting device 2, a pre-filtering device 3, a filtering blockage monitoring device 4 and a centrifugal filtering device 5 which are sequentially connected through pipelines; the filter plugging monitoring device also comprises a first water outlet pipe 601 and a second water outlet pipe 602, wherein the first water outlet pipe 601 is connected with the filter plugging monitoring device 4, and the second water outlet pipe 602 is connected with the centrifugal filter device 5; the sand setting device 2 is provided with a sand outlet 201, and the front filter device 3 is provided with a deslagging port 303.

The working process of the device is as follows:

the water can flow in the device by using the gravity of the water when entering from the water inlet pipe, and a water pump can be arranged in the device to realize the water inlet and the water flow in the device when necessary. A water sample firstly enters a sand setting device through a water inlet pipe, and sand setting filtration is carried out to remove silt and algae in the water sample. After the water got into the sand setting device from the inlet tube, because the volume of sand setting device increases suddenly, the velocity of water reduces suddenly, and great silt particle of quality and alga can sink rapidly at the action of gravity, and the less water of quality then can circle round to rise to sand setting device top entering water inlet tank in, and the water yield can get into leading filter equipment through the pipeline after reaching the take the altitude in the water inlet tank. The water sample filters particle impurities in the water sample through the pre-filter device, then enters the filter blockage monitoring device, can be directly discharged through the first water outlet pipe if the requirement on the water quality of the water sample is not high, and can enter the centrifugal filter device for centrifugal filtration if the requirement on the water quality of the water sample is high, so that insoluble micro particle impurities in the water sample are removed, and then the water sample is discharged through the second water outlet pipe.

Adopt above-mentioned device, through multi-stage filtration, not only can get rid of silt sand, alga and large granule impurity in the water sample, can get rid of miniature granule impurity through centrifugal filter device moreover, not only reduce the consume to the device, guaranteed the quality of treating the monitoring water sample simultaneously, and then guaranteed to satisfy the quality factor and can monitor in the water sample environment that does not have impurity, guarantee monitoring data's accuracy. In addition, the device provided by the embodiment of the invention also comprises a filter blockage monitoring device, so that the blockage condition of the filter screen can be monitored, the blockage of the filter screen can be found in time, the normal work of the water quality monitoring and filtering device is ensured, and the accuracy of water quality monitoring factor data is further ensured.

In addition, the filter equipment that this embodiment provided has sand outlet and slagging-off mouth, and effectual cleaning device in time guarantees filter equipment's effective operation. Moreover, through setting up first outlet pipe and second outlet pipe, can satisfy the water sample filtration demand of different masses. When the requirement on the quality of a water sample is low in the monitoring of the water quality factor and a centrifugal filter device is not needed to remove insoluble micro particles, water can be discharged through the first water outlet pipe; when the requirement on the quality of a water sample is high in the monitoring of the water quality factor and insoluble micro particles need to be removed by using the centrifugal filter device, the water sample needs to enter the centrifugal filter device for centrifugal filtration after passing through the filter blockage monitoring device, and then is drained by the second water outlet pipe.

In one embodiment of the present invention, the heights of the first outlet pipe 601 and the second outlet pipe 602 are lower than the heights of the inlet pipe 1 and the sand settling device 2.

By adopting the structure, the water sample can enter the filtering device and flow in the device under the action of self gravity, and power driving equipment is not needed, so that the energy consumption is saved.

In this embodiment, the centrifugal filter device 5 is disposed below the filter clogging monitoring device 4.

In a preferred embodiment of the present invention, the pre-filter device 3 sequentially comprises a primary filter screen 301, a filter pipe 304 and a secondary filter screen 302, and the deslagging port 303 is arranged on the filter pipe 304.

Wherein, the first grade filter screen can be used for filtering the coarse grain in the water sample, and the second grade filter screen can be used for filtering the fine particle in the water sample. In the embodiment of the invention, the first-stage filter screen can adopt an 80-mesh metal filter screen, and the second-stage filter screen can adopt a 40-mesh metal filter screen.

In the embodiment of the present invention, the pre-filter 3 is horizontally disposed.

By adopting the structure, the speed of the water sample passing through the primary filter screen, the filter pipe and the secondary filter screen is lower, and the water sample is more sufficiently filtered.

In another preferred embodiment of the present invention, an inlet filter screen 101 is disposed at one end of the water inlet pipe 1 close to the sand settling device 2.

The filter screen is arranged at the inlet, so that larger impurities in the water sample can be filtered and removed, and the front-mounted filter device is protected.

Wherein, the magnetic floating body can be a magnetic ball with magnetism; the magnetic sensor may in particular be a magnetic inductor. Commercially available products can be used for both the magnetic ball and the magnetic sensor.

Under leading filter equipment normal use state, the water sample can be normal pass through leading filter equipment and enter into and filter and block up monitoring devices, and the water sample volume that filters promptly and block up monitoring devices is bigger, and the surface of water is than higher, and magnetic floating body floats on the surface of water, can keep away from magnetic sensor along with the water surface for magnetic sensor can't sense the signal of magnetic floating body. On the contrary, under the unusual user state of leading filter equipment, the unable normal leading filter equipment of passing through of water sample and entering into and filter and block up monitoring devices, the water sample volume in filtering and blocking monitoring devices promptly is less, and the surface of water is lower, and magnetic floating body floats on the surface of water, can be close to magnetic sensor along with the water surface for magnetic sensor senses the signal of magnetic floating body.

Therefore, when the magnetic sensor senses the signal of the magnetic floating body, the preposed filtering device is in an abnormal use state, such as the filter screen is blocked. Therefore, whether the front-end filtering device is in a normal working state can be determined according to whether the magnetic sensor senses signals.

Wherein, the outlet of the pre-filter device 3 is connected with the upper part of the box body 403 and is positioned above the magnetic floating body 401.
