Description

Technical Field

[0001] This utility model relates to the field of filter paper cleaning and regeneration technology, and in particular to a water quality testing filter paper cleaning and regeneration device. Background Technology

[0002] Water quality testing filter paper is a key consumable in environmental monitoring and industrial water treatment. Made from high-purity cellulose fibers, it has a three-dimensional porous structure with pore sizes typically ranging from 0.45 to 10 μm. Through physical retention and adsorption, this material effectively separates suspended solids, colloidal particles, and some dissolved impurities from water samples, and is widely used in total suspended solids determination, oil analysis, and microbial detection. Depending on their application, filter paper is divided into qualitative filter paper and quantitative filter paper. The latter is further subdivided into single-wash type (for iron salt removal) and double-wash type (for further removal of organic matter).

[0003] In existing technologies, filter paper is generally cleaned and regenerated by rinsing with clean water, soaking in chemical cleaning agents, and backwashing. However, when filter paper is fixed during the cleaning process, structural damage is easily caused, resulting in fiber breakage, decreased porosity, and affecting the regeneration effect of water quality testing filter paper. Utility Model Content

[0004] In view of this, the present invention proposes a water quality testing filter paper cleaning and regeneration device to solve the problems mentioned above.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A water quality testing filter paper cleaning and regeneration device includes a housing, a moving mechanism, a support plate, a clamping mechanism, and a controller. The moving mechanism is located at the bottom of the housing, and an opening is provided on one side of the housing. The moving mechanism drives the support plate to enter and exit the housing through the opening. A water tank is provided on the top surface of the support plate, and the top of the water tank is open. A support plate is provided inside the water tank. A first electric push rod is provided on the top surface of the support plate, and its telescopic end is connected to a U-shaped frame. The clamping mechanism is rotatably located in the middle of the U-shaped frame. The clamping mechanism includes a frame, hinges, and a wire mesh. Two frames are hinged together by the hinges. The wire mesh is located inside the frames. The frame is rotatably connected to a U-shaped frame on both sides via a rotating shaft. One end of the rotating shaft passes through the U-shaped frame and is connected to a first motor. The first motor is located on the side of the U-shaped frame. A second electric push rod and a fan are located on the top of the housing. The telescopic end of the second electric push rod is connected to a lifting plate. A water pump is located on the top surface of the housing. The water pump is connected to a nozzle via a water pipe. The nozzle is located on the bottom surface of the lifting plate. A fan is located at the bottom of the housing. A ventilation hole is located on the top of the housing, above the fan. The controller is located on the side of the housing and is electrically connected to the moving mechanism, the first motor, the first electric push rod, the second electric push rod, and the fan.

[0007] Preferably, the moving mechanism includes a lead screw, a moving block, and a second motor. The lead screw is rotatably disposed at the bottom of the housing, with one end rotatably connected to the housing and the other end passing through the housing and driving the second motor. The second motor is disposed on the side of the housing. The moving block is disposed on the lead screw and slidably connected to the bottom of the housing. The bearing plate is disposed on the side of the moving block.

[0008] Preferably, the clamping mechanism further includes a mesh grid, which is disposed in the middle of the frame, and the wire mesh is disposed in the middle of the mesh grid.

[0009] Preferably, the mesh grid is made of a magnetic material with opposite magnetic properties.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. A clamping mechanism is set up, which is equipped with a wire mesh. The wire mesh flexibly clamps the filter paper on both sides to prevent the filter paper from becoming loose during the cleaning process. The pre-soaking and multi-angle cleaning are adopted so that the clamping mechanism, water flow and air flow are at different angles, which helps to improve the cleaning and drying effect on both sides of the filter paper and prevents the filter paper from shifting during the cleaning process, which would cause the filter paper fibers to break and affect the regeneration effect of the filter paper.

[0016] 2. An ultrasonic oscillator is installed. The ultrasonic generator produces oscillation waves. When the ultrasonic waves propagate in the cleaning fluid, they generate alternating high-pressure and low-pressure zones. Vacuum bubbles are formed in the low-pressure zone. The bubbles collapse instantaneously in the high-pressure zone, releasing shock waves, which peel off the dirt on the surface of the filter paper and improve the cleaning effect of the filter paper.

[0023] See Figures 1 to 3This utility model provides a water quality testing filter paper 25 cleaning and regeneration device, including a housing 1, a moving mechanism, a support plate 6, a clamping mechanism, and a controller 20. The moving mechanism is located at the bottom of the housing 1, and an opening 2 is provided on one side of the housing 1. The moving mechanism drives the support plate 6 to enter and exit the housing 1 through the opening 2. A water tank 9 is provided on the top surface of the support plate 6. The top of the water tank 9 is open, and a support plate 8 is provided inside. A first electric push rod 10 is provided on the top surface of the support plate 8, and its telescopic end is connected to a U-shaped frame 11. The clamping mechanism is rotatably located in the middle of the U-shaped frame 11. The clamping mechanism includes a frame 12, a hinge 23, and a wire mesh 24. The two frames 12 are hinged together by the hinge 23. The wire mesh 24 is located inside the frame 12. The two sides of the frame 12 are rotatably connected to the U-shaped frame by a rotating shaft 26. 11. One end of the rotating shaft 26 passes through the U-shaped frame 11 and is driven by the first motor 4. The first motor 4 is located on the side of the U-shaped frame 11. The top of the housing 1 is provided with a second electric push rod 17 and a fan 22. The telescopic end of the second electric push rod 17 is connected to a lifting plate 18. The top surface of the housing 1 is provided with a water pump 15. The water pump 15 is connected to a nozzle 14 through a water pipe 16. The nozzle 14 is located on the bottom surface of the lifting plate 18. The bottom of the housing 1 is provided with a fan 22. The top of the housing 1 is provided with a ventilation hole 21. The ventilation hole 21 is located above the fan 22. The controller 20 is located on the side of the housing 1 and is electrically connected to the moving mechanism, the first motor 4, the first electric push rod 10, the second electric push rod 17 and the fan 22. The controller 20 uses a low-power microprocessor of model STM32-L0.

[0024] When cleaning the water quality testing filter paper 25, firstly, the cleaning solution is injected into the water tank 9. Then, the moving mechanism is activated, driving the support plate 6 to move out of the opening 2 of the housing 1, thus moving the water tank 9 outside the housing 1. The operator opens the clamping mechanism, then lays the filter paper 25 to be cleaned flat on the wire mesh 24, and then closes the clamping mechanism. The wire mesh 24 on both sides brings the top and bottom surfaces of the filter paper 25 close together, thus completing the limiting of the filter paper 25. The moving mechanism is activated again to move the water tank 9 into the housing 1. The first electric push rod 10 is activated, and the telescopic end of the first electric push rod 10 shortens, causing the U-shaped frame 11 to descend, lowering the clamping mechanism and the filter paper 25 below the surface of the cleaning solution for soaking. After the predetermined soaking time is completed, the first motor 4 is activated, driving the U-shaped frame 11 to rotate, causing the U-shaped frame 11 to swing back and forth in the cleaning solution, softening and shaking off the filter residue on the side panel of the filter paper 25. After the filter paper 25 is soaked, the moving mechanism is activated to move the water tank 9 below the nozzle 14. The first electric actuator 10 is activated, and its telescopic end extends, causing the clamping mechanism to lift the filter paper 25 above the cleaning liquid surface. The second electric actuator 17 is activated, and its telescopic end extends, causing the lifting plate 18 to descend. The descending lifting plate 18 causes the nozzle 14 to descend to the predetermined height. Then, the water pump 15 is activated, and the water pump 15 sprays clean water through the water pipe 16 from the nozzle 14. The water flow washes the filter paper 25 in the middle of the clamping mechanism. At the same time, the... The first motor 4 is activated, which drives the U-shaped frame 11 to rotate, making the clamping mechanism and the water flow at different angles, which is beneficial to improving the cleaning effect on both sides of the filter paper 25. After cleaning is completed, the moving mechanism is activated to move the water tank 9 below the fan 22. The fan 22 is activated, and the fan 22 generates airflow that blows towards the filter paper 25 in the middle of the clamping mechanism. At the same time, the first motor 4 is activated, which drives the U-shaped frame 11 to rotate, making the clamping mechanism and the airflow at different angles, which is beneficial to improving the drying effect on both sides of the filter paper 25 and improving the regeneration efficiency of the filter paper 25.

[0025] Preferably, the moving mechanism includes a lead screw 3, a moving block 5, and a second motor. The lead screw 3 is rotatably disposed at the bottom of the housing 1, with one end rotatably connected to the housing 1 and the other end passing through the housing 1 and driving the second motor. The second motor is disposed on the side of the housing 1. The moving block 5 is disposed on the lead screw 3 and slidably connected to the bottom of the housing 1. The bearing plate 6 is disposed on the side of the moving block 5.

[0026] The moving mechanism is used to drive the support plate 6 to enter and exit the box 1 through the side opening 2 of the box 1. When the support plate 6 needs to move, the second motor is started. The rotation of the second motor drives the lead screw 3 to rotate. The moving block 5 is screwed to the lead screw 3, thereby driving the moving block 5 to move along the axial direction of the lead screw 3. The movement of the support plate 6 drives the water tank 9 to move out of the box 1, which can complete the loading and clamping of the filter paper 25.

[0027] Preferably, the clamping mechanism further includes a mesh grid 13, which is disposed in the middle of the frame 12, and the wire mesh 24 is disposed in the middle of the mesh grid 13.

[0028] Multiple wire meshes 24 are arranged in the middle of the mesh grid 13, and multiple sheets of filter paper 25 to be cleaned and regenerated are clamped on the corresponding wire meshes 24. Multiple sheets of filter paper 25 can be limited at the same time, thereby improving the cleaning and regeneration efficiency of filter paper 25.

[0029] Preferably, the mesh grid 13 is made of a magnetic material with opposite magnetic properties.

[0030] When the upper and lower frames 12 are attached together, the magnetic materials of the mesh grid 13 are opposite, generating magnetic force to attract each other, thereby better limiting the filter paper 25.

[0031] Preferably, an ultrasonic generator 7 is also included, which is located at the bottom of the water tank 9 and electrically connected to the controller 20.

[0032] When the first electric actuator 10 is activated, its telescopic end shortens, causing the U-shaped frame 11 to descend into the cleaning fluid. Then, the ultrasonic generator 7 is activated, generating oscillation waves. As the ultrasonic waves propagate in the liquid, they generate alternating high-pressure and low-pressure zones. Vacuum bubbles are formed in the low-pressure zone, and the bubbles collapse instantaneously in the high-pressure zone, releasing shock waves that peel off dirt from the surface of the filter paper 25, thus improving the cleaning effect of the filter paper 25.

[0033] Preferably, the system also includes a discharge pipe 29 and a discharge valve 28, wherein the discharge pipe 29 is located at the bottom of the water tank 9 and the discharge valve 28 is located on the discharge pipe 29.

[0034] After the filter paper 25 is soaked, the waste residue and other contaminants in the filter paper 25 dissolve in the cleaning solution. Open the drain valve 28 to discharge the wastewater into the water tank 9 through the drain pipe 29.

[0035] Preferably, a transparent observation window 27 is also included, which is located on the side of the housing 1.

[0036] When the water tank 9 is located in the tank 1, during the soaking, rinsing and drying of the filter paper 25, the operator can observe the relevant operations of the filter paper 25 through the transparent observation window 27, which is conducive to timely adjustment of the relevant operations of the filter paper 25.

[0037] Preferably, a partition 19 is also included, which is disposed on the top surface of the housing 1 and located between the second electric push rod 17 and the fan 22.

[0038] The partition 19 is used to isolate the fan 22 and the second electric actuator 17. When the fan 22 adopts the hot air drying mode, the partition 19 plays the role of guiding the air, avoiding the dispersion of hot air and improving the drying efficiency.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
