Description

Technical Field

[0001] The invention belongs to the technical field of wastewater filtration of water jet looms, and specifically refers to a water circulation filtration device for a polymer fabric water jet loom. Background Art

[0002] A water jet loom is a shuttleless loom that uses a jet of water to pull the weft yarn through the shed. The frictional traction of water jet weft insertion on the weft yarn is greater than that of air jet weft insertion, and its diffusion is small. It is suitable for the weft insertion of smooth-surfaced synthetic fibers, glass fibers and other filaments. A water jet loom requires a large amount of water in the production process, and it is converted into wastewater in the production process. However, the wastewater generated cannot be recycled, resulting in a serious waste of water resources.

[0003] The existing water circulation filter device of water jet loom has the following problems:

[0004] The existing water circulation filtering device of the water jet loom does not have the function of autonomously regulating the flow rate of the wastewater. When the flow rate of the wastewater flowing through the filtering device increases, the filtering efficiency of the filter material on the impurities in the wastewater is reduced. Moreover, when the traditional filtering device adopts a filter screen to intercept the impurities in the wastewater, the filter screen does not have an automatic cleaning function, which leads to the clogging of the filter screen after long-term use, thereby reducing the filtering efficiency of the filtering device on the wastewater generated by the water jet loom. Therefore, it cannot meet the existing use requirements of the water circulation filtering device of the water jet loom. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present scheme provides a water circulation filtration device of a polymer fabric water jet loom, which can automatically adjust the filtration speed of the wastewater by the filter material according to the flow rate of the wastewater, ensure that the filter material efficiently filters the impurities in the wastewater, and can automatically clean the filter screen to ensure the pass rate of the filter screen for wastewater, and can also reduce the wear rate of impurities in the wastewater on the inner wall of the pipe.

[0006] The technical scheme adopted in this scheme is as follows: This scheme proposes a water circulation filtration device for a polymer fabric water jet loom, comprising a filter ring cylinder, a blockage-reducing cyclone filter mechanism and a pressure-reducing speed-reducing flow mechanism, wherein the blockage-reducing cyclone filter mechanism is arranged inside, and the pressure-reducing speed-reducing flow mechanism is arranged on the side wall of the filter ring cylinder, the blockage-reducing cyclone filter mechanism comprises a water supply mechanism and a filtering mechanism, the water supply mechanism is arranged on the inner wall of the filter ring cylinder, and the filtering mechanism is arranged on the inner wall of the filter ring cylinder on one side of the water supply mechanism, the pressure-reducing speed-reducing flow mechanism comprises a flow reducing mechanism, a pressure collecting mechanism and an adsorption mechanism, the flow reducing mechanism is arranged on the side wall of the filter ring cylinder, the pressure collecting mechanism is arranged on the flow reducing mechanism, and the adsorption mechanism is arranged on one side of the flow reducing mechanism.

[0007] As a further preferred embodiment of the present invention, the water delivery mechanism includes a water delivery frame, a water collecting cylinder, a filter cylinder, a liquid flow measuring valve, a telescopic tube and a controller. The water delivery frame is symmetrically arranged on the inner walls at both ends of the filter ring cylinder, the water collecting cylinder is arranged on the inner wall of the water delivery frame, the filter cylinder is rotatably arranged between the water collecting cylinders, the water collecting cylinder and the filter cylinder are connected, the liquid flow measuring valve is connected to the side wall of the water collecting cylinder arranged at one end of the filter cylinder, and multiple groups of telescopic tubes are connected to the side wall of the water collecting cylinder arranged on the side of the filter cylinder away from the liquid flow measuring valve; the filtering mechanism includes a driving coil, a driving magnet, an annular plate and a filter screen, the driving coil is symmetrically arranged on the outside of both ends of the filter cylinder, the driving magnet is arranged on the inner wall of the filter ring cylinder outside the driving coil, the driving coil and the driving magnet are arranged opposite to each other, multiple groups of annular plates are arranged on the inner wall of the filter cylinder, the filter screen is arranged on the inner wall of the annular plate, the thickness of the filter screen is greater than the thickness of the annular plate, and an annular groove is arranged between the annular plate and the filter screen.

[0008] When in use, the waste water generated by the water jet loom is connected to the liquid flow measuring valve through an external pipe, and the waste water generated by the water jet loom enters the filter cylinder through the liquid flow measuring valve and the water collecting cylinder. The filter net arranged inside the filter cylinder filters the larger impurities in the waste water of the water jet loom. In order to prevent the impurities from clogging the filter net, the driving coil is energized and magnetism is generated between the driving magnet. The filter cylinder rotates under the action of the magnetic field between the driving coil and the driving magnet, and the filter cylinder drives the waste water inside it to perform centrifugal motion, so that the impurities are separated from the waste water and fit the inner wall of the filter cylinder. With the unidirectional flow of the waste water, the impurities separated by centrifugation move along the inner wall of the filter cylinder and enter the groove formed between the filter net and the annular plate, thereby reducing the probability of impurities flowing with the waste water. The waste water filtered by the filter net is discharged through the telescopic tube.

[0009] Preferably, the flow reduction mechanism comprises a flow reduction block, a flow guide tube, a flow guide joint, a distance-adjusting spring, a distance-adjusting magnet, a fixed electromagnet, an adsorption tube and an elastic spiral tube. Multiple groups of the flow reduction blocks are arranged on the side wall of one end of the filter ring tube, the flow guide tube is arranged through the end of the flow reduction block away from the filter ring tube, the end of the telescopic tube away from the water collecting tube is connected with the flow guide tube, the flow guide joint is connected and arranged on the side of the flow guide tube away from the telescopic tube, multiple groups of the adsorption tubes are arranged on the side wall of the end of the filter ring tube away from the flow reduction block, the elastic spiral tube is connected and arranged between the adsorption tube and the flow guide joint, the distance-adjusting spring is arranged between the flow reduction block and the flow guide joint outside the flow guide tube, the fixed electromagnet is arranged on the side of the flow reduction block outside the flow guide tube away from the distance-adjusting spring, the distance-adjusting magnet is arranged at the end of the flow guide tube away from the flow guide joint, and the distance-adjusting magnet is arranged opposite to the fixed electromagnet; the pressure receiving mechanism comprises a buffer arc tube, a guide block, a guide rod, a guide ball tube, a fixed plate, an arc buffer spring and a buffer ball The buffer arc tube is connected and arranged between the bending parts of the elastic spiral tube, and the buffer arc tube is rotatably arranged on the side wall of the elastic spiral tube. The guide ball cylinder is penetrated and arranged in the middle part of the buffer arc tube, and the guide ball cylinder is connected and arranged with the buffer arc tube. The fixed plate is arranged inside the guide ball cylinder, and multiple groups of guide blocks are arranged on the side wall of one end of the filter ring cylinder close to the adsorption cylinder. The guide rod penetrates the guide ball cylinder and the fixed plate is arranged on the side wall of the guide block. The guide ball cylinder and the fixed plate are slidably arranged on the outside of the guide rod. The arc buffer spring is symmetrically arranged inside the buffer arc tube on both sides of the fixed plate, and the buffer ball is arranged on the side of the arc buffer spring away from the fixed plate. The diameter of the buffer ball is consistent with the inner diameter of the buffer arc tube; the adsorption mechanism includes an adsorption tube, a lightweight porous ceramic filter material layer and a drain valve. The adsorption tube is connected and arranged between the adsorption cylinder and the filter ring cylinder, and the lightweight porous ceramic filter material layer is arranged inside the filter ring cylinder. Multiple groups of drain valves are connected and arranged on the side of the filter ring cylinder away from the adsorption tube.

[0010] When in use, the speed of the wastewater flowing through the filter device is adjusted according to the flow rate of the wastewater detected by the liquid flow measuring valve, so as to better filter and adsorb impurities in the wastewater. In the initial state, the distance adjusting spring is shortened, the distance between the distance adjusting magnet and the fixed electromagnet is at the maximum value, and the elastic spiral tube is extended. At this time, the resistance encountered by the liquid flowing through the elastic spiral tube is minimal. After being filtered by the filter cartridge, the wastewater flows into the guide tube through the telescopic tube. The wastewater in the guide tube passes through the elastic spiral tube and the adsorption tube into the filter ring tube. After being adsorbed by the lightweight porous ceramic filter material layer inside the filter ring tube, the wastewater is discharged through the drain valve, thereby completing the filtration operation of the wastewater.

[0011] When the liquid flow measurement valve tests that the flow rate of the wastewater is accelerated, in order to avoid the phenomenon that the lightweight porous ceramic filter material layer is blocked due to the excessive filtering speed, the fixed electromagnet is energized to generate magnetism, the fixed electromagnet and the adjustable distance magnet are set with opposite poles, the fixed electromagnet is fixed to the side wall of the flow reduction block to absorb the adjustable distance magnet by magnetic force, the adjustable distance magnet drives the guide tube to slide along the flow reduction block through the stretching of the telescopic tube, the guide tube drives the elastic spiral tube to be compressed through the deformation of the adjustable distance spring, so that the spiral pitch of the elastic spiral tube is shortened, and the shortening of the spiral pitch of the elastic spiral tube increases the flow resistance of the wastewater in the tube, thereby reducing the flow speed of the wastewater, which is convenient for the lightweight porous ceramic filter material layer to adsorb impurities in the wastewater;

[0012] The wastewater of water jet loom mainly comes from weaving, dyeing, finishing and other processes, which contains a large amount of impurities such as dyes, additives, oil, fiber scraps, etc., which leads to a relatively high viscosity of the wastewater. When the resistance of the wastewater with high viscosity increases inside the elastic spiral tube, it will increase the wear of the inner wall of the elastic spiral tube. Therefore, when the flow rate of the wastewater is accelerated and the pitch of the elastic spiral tube is shortened, the wastewater will increase the erosion of the bending part of the elastic spiral tube. In the initial state, the arc buffer spring is extended, and the buffer ball is located at the connection between the elastic spiral tube and the buffer arc tube. When the wastewater inside the elastic spiral tube flows through its bending part, the wastewater impacts the bending part of the elastic spiral tube. The buffer ball is arranged in the position, and the buffer ball slides into the inside of the buffer arc tube through the deformation of the arc buffer spring, thereby avoiding the wear of the wastewater on the bending part of the elastic spiral tube. When the flow speed of the wastewater increases again, the pitch of the elastic spiral tube is shortened, and the wastewater moves in a straight line along the unbent part of the elastic spiral tube to impact the buffer ball. The buffer ball squeezes the arc buffer spring, and the deformation degree of the buffer ball increases, which can reduce the wear rate of the bending part of the elastic spiral tube, ensure the service life of the elastic spiral tube in the wastewater filtration operation, and control the flow speed of the wastewater through the stretching and compression of the elastic spiral tube, thereby improving the filtration efficiency of the lightweight porous ceramic filter material layer for wastewater.

[0013] Specifically, a controller is provided on the side wall of the filter ring cylinder.

[0014] Wherein, the controller is electrically connected to the liquid flow measurement valve, the drive coil and the fixed electromagnet respectively.

[0015] Preferably, the model of the liquid flow measuring valve is 3 / 4 CSM-61-M1-S 0856737.

[0016] The beneficial effects achieved by adopting the above structure are as follows:

[0017] Compared with the prior art, this solution adopts a method of adjusting the flow speed of wastewater. By setting up a blockage-reducing cyclone filter mechanism and a pressure-reducing flow-speed-reducing mechanism, the flow speed of wastewater with a faster flow speed entering the filtering device can be controlled under the cooperation of the water delivery mechanism, the filtering mechanism, the flow-reducing mechanism, the pressure-collecting mechanism and the adsorption mechanism, and the wear of the inner wall of the elastic spiral tube caused by the wastewater when the resistance increases can be avoided, so that the elastic spiral tube can transport wastewater with high viscosity and large resistance under low wear, and the control of the wastewater flow rate by the elastic spiral tube can improve the filtering and adsorption efficiency of the lightweight porous ceramic filter material layer on the wastewater. Secondly, by setting the thickness of the filter screen to be greater than the thickness of the annular plate, a groove is formed between the annular plate and the filter screen. The invention is convenient for intercepting impurities after centrifugal separation, reducing impurities in wastewater, and indirectly reducing the wear rate of the particulate impurities in the wastewater on the inner wall of the elastic spiral tube, and to a certain extent improving the filtering efficiency of the plugging-reducing cyclone filter mechanism and the water delivery mechanism for wastewater. The fixed electromagnet and the adjustable pitch magnet are arranged with different poles, and the fixed electromagnet is fixed on the side wall of the flow reduction block to absorb the adjustable pitch magnet by magnetic force. The adjustable pitch magnet drives the guide tube to slide along the flow reduction block through the stretching of the telescopic tube, and the guide tube drives the elastic spiral tube to be compressed through the deformation of the adjustable pitch spring, so that the spiral pitch of the elastic spiral tube is shortened. The shortening of the spiral pitch of the elastic spiral tube will increase the flow resistance of the wastewater in the tube, thereby reducing the flow speed of the wastewater, and facilitating the lightweight porous ceramic filter material layer to adsorb impurities in the wastewater.

[0038] A controller 9 is disposed on the side wall of the filter ring cylinder 1 .

[0039] The controller 9 is electrically connected to the liquid flow measurement valve 7 , the drive coil 11 and the fixed electromagnet 22 , respectively.

[0040] The model of the liquid flow measurement valve 7 is 3 / 4 CSM-61-M1-S 0856737.

[0041] When in use, the wastewater generated by the water jet loom is connected to the liquid flow measurement valve 7 through an external pipe, and the wastewater generated by the water jet loom passes through the liquid flow measurement valve 7 and the water collecting cylinder 5 and enters the filter cylinder 6. The filter net 14 arranged inside the filter cylinder 6 filters the larger impurities in the wastewater of the water jet loom;

[0042] Specifically, in order to prevent impurities from clogging the filter screen 14, the controller 9 controls the drive coil 11 to start, and the drive coil 11 is energized to generate magnetism with the drive magnet 12. The filter cartridge 6 rotates under the force of the magnetic field between the drive coil 11 and the drive magnet 12, and the filter cartridge 6 drives the wastewater inside it to perform centrifugal motion, so that the impurities are separated from the wastewater and adhere to the inner wall of the filter cartridge 6. With the unidirectional flow of the wastewater, the impurities separated by centrifugation move along the inner wall of the filter cartridge 6 and enter the groove formed between the filter screen 14 and the annular plate 13, thereby reducing the probability of impurities flowing with the wastewater. The wastewater filtered by the filter screen 14 is discharged through the telescopic tube 8.

[0043] The controller 9 controls the liquid flow measuring valve 7 to start, and the liquid flow measuring valve 7 detects the flow rate of the wastewater flowing through. According to the flow rate of the wastewater detected by the liquid flow measuring valve 7, the speed of the wastewater flowing through the filtering equipment is adjusted to facilitate better filtering and adsorbing impurities in the wastewater. In the initial state, the adjustable spring 20 is shortened, the distance between the adjustable magnet 21 and the fixed electromagnet 22 is the maximum value, and the elastic spiral tube 24 is extended. At this time, the resistance encountered by the liquid flowing through the elastic spiral tube 24 is the smallest. After being filtered by the filter cartridge 6, the wastewater flows into the guide tube 18 through the telescopic tube 8. The wastewater in the guide tube 18 enters the filter ring cylinder 1 through the elastic spiral tube 24 and the adsorption tube 34. After being adsorbed by the lightweight porous ceramic filter material layer 35 inside the filter ring cylinder 1, the wastewater is discharged through the drain valve 36, completing the filtration operation of the wastewater.

[0044] When the liquid flow measurement valve 7 tests that the flow rate of the wastewater is accelerated, in order to avoid the phenomenon that the lightweight porous ceramic filter material layer 35 is blocked due to the excessive filtering speed, the controller 9 controls the fixed electromagnet 22 to start, and the fixed electromagnet 22 is energized to generate magnetism. The fixed electromagnet 22 and the adjustable distance magnet 21 are arranged with opposite poles. The fixed electromagnet 22 is fixed on the side wall of the flow reduction block 17 to absorb the adjustable distance magnet 21 by magnetic force. The adjustable distance magnet 21 drives the guide tube 18 to slide along the flow reduction block 17 through the stretching of the telescopic tube 8. The guide tube 18 drives the elastic spiral tube 24 to be compressed through the deformation of the adjustable distance spring 20, so that the spiral pitch of the elastic spiral tube 24 is shortened. The shortening of the spiral pitch of the elastic spiral tube 24 will increase the flow resistance of the wastewater in the tube, thereby reducing the flow speed of the wastewater, which is convenient for the lightweight porous ceramic filter material layer 35 to adsorb impurities in the wastewater;

[0045] However, since the wastewater of the water jet loom mainly comes from the weaving, dyeing, finishing and other processes, it contains a large amount of impurities such as dyes, additives, oil, fiber scraps, etc., which leads to a relatively high viscosity of the wastewater. When the resistance of the wastewater with high viscosity increases inside the elastic spiral tube 24, the wear force on the inner wall of the elastic spiral tube 24 will be increased. Therefore, when the flow rate of the wastewater is accelerated and the pitch of the elastic spiral tube 24 is shortened, the wastewater will increase the erosion of the curved part of the elastic spiral tube 24;

[0046] In the initial state, the arc buffer spring 31 is extended, and the buffer ball 32 is located at the connection point between the elastic spiral tube 24 and the buffer arc tube 26. When the wastewater inside the elastic spiral tube 24 flows through its bend, the wastewater impacts the buffer ball 32 arranged at the bend of the elastic spiral tube 24. The buffer ball 32 is deformed and slides into the buffer arc tube 26 through the arc buffer spring 31, thereby avoiding the wear of the bend of the elastic spiral tube 24 by the wastewater, and elastically buffering the impact force of the wastewater. When the flow speed of the wastewater increases again, the controller 9 controls the current passed into the fixed electromagnet 22 to increase, and the fixed electromagnet 22 drives the guide tube 18 to compress the elastic spiral tube 24 by adsorbing the pitch-adjusting magnet 21. The pitch of the elastic spiral tube 24 is shortened again, and the wastewater flows along the elastic The unbent part of the spiral tube 24 performs linear motion to impact the buffer ball 32, and the buffer ball 32 squeezes the arc buffer spring 31. The deformation degree of the buffer ball 32 increases to buffer the impact force of the wastewater, thereby reducing the wear rate of the bending part of the elastic spiral tube 24, ensuring the service life of the elastic spiral tube 24 in the wastewater filtration operation, and controlling the flow speed of the wastewater by stretching and compressing the elastic spiral tube 24, which can improve the filtration efficiency of the lightweight porous ceramic filter material layer 35 for the wastewater. The wastewater in the guide tube 18 that has been regulated by the speed passes through the elastic spiral tube 24 and the adsorption tube 34 into the filter ring tube 1. The wastewater is adsorbed by the lightweight porous ceramic filter material layer 35 inside the filter ring tube 1 and is discharged through the drain valve 36; the above operation can be repeated when used next time.
