Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically, to a wastewater filtration structure for a water jet loom. Background Technology

[0002] Water jet looms are shuttleless looms that use jet water to pull the weft yarn through the shed. Water jet weft insertion has a greater frictional pulling force on the weft yarn than air jet weft insertion, and has less diffusion. It is suitable for the weft insertion of filaments such as synthetic fibers and glass fibers with smooth surfaces. Water jet looms generate a large amount of wastewater containing textile fibers during weaving.

[0003] To save water consumed by water jet looms, wastewater is usually filtered through a filter structure before being recycled. However, existing wastewater filter structures cannot be self-cleaning, requiring staff to clean the filter components regularly, which increases the workload of the staff.

[0004] Chinese patent CN218794123U discloses a wastewater filtration structure for water jet looms, which automatically cleans the filter elements during the wastewater filtration process, preventing clogging, improving the filtration effect, and reducing the workload of workers, saving time and effort.

[0005] Although the aforementioned patent can clean the filter at any time, during operation, according to Bernoulli's principle (that air has low pressure at high velocity), the pressure is low where water has high velocity. Therefore, when water flows, the impurities cleaned off the filter tend to approach the filter again. Thus, even when the cleaning rod is no longer in contact with the filter, the impurities are still carried to the surface of the filter by the water flow, resulting in the filter remaining clogged for a period of time.

[0006] Therefore, a wastewater filtration structure for water jet looms is proposed. Summary of the Invention

[0007] To address the problems existing in the prior art, the purpose of this invention is to provide a wastewater filtration structure for water jet looms that can ensure filtration effect and shorten the time when the first filter screen is clogged.

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A wastewater filtration structure for a water-jet loom includes a box with a drain outlet at the top and an inlet pipe. The output end of the inlet pipe is connected to the box. A first filter screen is slidably disposed inside the box. A limiting block is provided on the inner wall of the box below the first filter screen. An elastic element is provided between the first filter screen and the top wall of the box. A transfer box is inserted into the bottom wall of the box. An installation rod is vertically rotatably disposed inside the box. Stirring rods are evenly inserted into the installation rod to generate vortices. A motor with its output end cooperating with the installation rod is fixedly installed on the transfer box. A scraper is provided at the top of the side wall of the installation rod. A collection box communicating with both the transfer box and the box is provided on the side wall of the box. An upper horizontal pipe communicating with the box is inserted into the side wall of the collection box. A transfer mechanism cooperating with the collection box is provided inside the transfer box. A pressure-reducing mechanism cooperating with the scraper is provided on the installation rod.

[0010] Furthermore, a sieve plate is hinged to the inner side wall of the collection box, the sieve plate covers the end face of the upper horizontal tube located inside the collection box, a first magnet is fixedly installed on the side wall of the sieve plate, and a second magnet that cooperates with the first magnet is embedded in the scraper.

[0011] Furthermore, the transfer mechanism includes a reciprocating lead screw fixedly installed on the output end of the motor, a pressure plate threaded onto the reciprocating lead screw, a first one-way valve embedded in the pressure plate, and a lower horizontal pipe connected to the transfer box inserted into the side wall of the collection box.

[0012] Furthermore, the pressure reducing mechanism includes a mounting groove at the top of the mounting rod, a push rod is movably disposed in the mounting groove, the ratio of the depth of the mounting groove to the length of the push rod is 5:1, a spring is provided between the push rod and the mounting groove, a threaded hole is provided on the mounting rod, and the reciprocating lead screw is threadedly installed in the threaded hole.

[0013] A second filter screen is embedded in the side wall of the scraper, and the diameter of the holes in the second filter screen is smaller than the diameter of the holes in the first filter screen.

[0014] Furthermore, sleeves are evenly inserted into the top wall of the box, and elastic strips are provided inside the sleeves, with impact rods fixedly installed on the elastic strips.

[0015] Furthermore, an installation hole is provided on the bottom wall of the stirring rod, and a diaphragm of elastic material is fixedly installed in the installation hole. A drain valve is embedded in the diaphragm, and a water inlet valve is embedded in the top wall of the installation hole.

[0016] Furthermore, an elastic membrane is fixedly installed between the side wall of the pressure plate and the inner side wall of the transfer box.

[0017] Furthermore, there are multiple water inlet pipes, which are evenly inserted into the bottom wall of the box, and the inner side wall of the box is evenly provided with baffles.

[0018] Furthermore, a second one-way valve is embedded inside the lower horizontal tube.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. By setting up an installation rod, stirring rod, installation groove, and top rod, the installation rod and stirring rod generate a vortex in the space below the first filter screen. The generated vortex sucks in impurities located below the first filter screen in the box, thereby reducing the amount of impurities adhering to the bottom wall of the first filter screen. When the first filter screen moves upward momentarily, some impurities on the bottom wall of the first filter screen can be separated from the first filter screen. Then, the upward-moving scraper will contact the impurities suspended below the first filter screen and move the impurities together. When the spring is squeezed, the scraper will contact and scrape the bottom wall of the first filter screen for a period of time, thereby improving the cleaning effect of the first filter screen. Compared with directly scraping the surface of the first filter screen, it can prevent a large number of impurities from being squeezed into the holes of the first filter screen by the scraper.

[0021] 2. By setting up a reciprocating screw, pressure plate, and elastic diaphragm, impurities in the transfer box can be transferred in a timely manner, thereby reducing the impurity content in the transfer box and ensuring that impurities above the pressure plate can pass through the first one-way valve and move downward normally.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] Example 1:

[0033] Please see Figures 1 to 6 A wastewater filtration structure for a water-jet loom includes a housing 1 with a drain outlet at the top and a water inlet pipe 2. The output end of the water inlet pipe 2 is connected to the housing 1. A first filter screen 3 is slidably disposed inside the housing 1. A limiting block 33 is provided on the inner wall of the housing 1 below the first filter screen 3. An elastic element 34 is provided between the first filter screen 3 and the inner top wall of the housing 1. A transfer box 4 is inserted into the bottom wall of the housing 1. An installation rod 5 is vertically rotatably disposed inside the housing 1. The installation rod 5 is evenly inserted with... A stirring rod 6 is provided to generate a vortex. A motor 7 with its output end cooperating with a mounting rod 5 is fixedly installed on the transfer box 4. A scraper 8 is provided at the top of the side wall of the mounting rod 5. A collection box 9 communicating with both the transfer box 4 and the box 1 is provided on the side wall of the box body 1. An upper horizontal pipe 10 communicating with the box body 1 is inserted into the side wall of the collection box 9. A transfer mechanism cooperating with the collection box 9 is provided inside the transfer box 4. A pressure reduction mechanism cooperating with the scraper 8 is provided on the mounting rod 5.

[0034] A sieve plate 11 is hinged to the inner side wall of the collection box 9. The sieve plate 11 covers the end face of the upper horizontal tube 10 located inside the collection box 9. A first magnet 12 is fixedly installed on the side wall of the sieve plate 11, and a second magnet 13 that cooperates with the first magnet 12 is embedded on the scraper 8.

[0035] The transfer mechanism includes a reciprocating lead screw 14 fixedly installed on the output end of the motor 7. A pressure plate 15 is threaded onto the reciprocating lead screw 14. The side wall of the pressure plate 15 is in contact with the inner side wall of the transfer box 4. A first one-way valve 16 is embedded in the pressure plate 15. A lower horizontal pipe 17 communicating with the transfer box 4 is inserted into the side wall of the collection box 9.

[0036] The pressure relief mechanism includes a mounting groove 18 at the top of the mounting rod 5, a push rod 19 is movably disposed in the mounting groove 18, the ratio of the depth of the mounting groove 18 to the length of the push rod 19 is 5:1, a spring 20 is provided between the push rod 19 and the mounting groove 18, a threaded hole 21 is provided on the mounting rod 5, and the reciprocating screw 14 is threadedly installed in the threaded hole 21.

[0037] A second filter screen 23 is embedded on the side wall of the scraper 8, and the diameter of the holes on the second filter screen 23 is smaller than the diameter of the holes on the first filter screen 3.

[0038] During operation, wastewater is introduced into the tank 1 through the inlet pipe 2. At this time, the liquid level in the tank 1 gradually rises and gradually submerges the first filter screen 3, so that the impurities in the wastewater can be filtered out through the first filter screen 3. Finally, the filtered water flows out through the drain outlet on the top wall of the tank 1.

[0039] During the filtration process, the motor 7 is started. At this time, the motor 7 drives the mounting rod 5 to rotate through the reciprocating screw 14. This causes the mounting rod 5 and the stirring rod 6 to generate a vortex in the space below the first filter screen 3. The generated vortex sucks in the impurities located below the first filter screen 3 in the box 1, thereby reducing the amount of impurities attached to the bottom wall of the first filter screen 3. Furthermore, under the action of the vortex, the impurities attached to the bottom wall of the first filter screen 3 are subjected to downward attraction.

[0040] During normal operation, sewage is continuously fed into the tank 1. At this time, the water pressure in the tank 1 is relatively high. The water pressure pushes the first filter screen 3 upward and filters the sewage at the same time. However, under the action of the elastic element 34, the upward thrust is balanced. At this time, the first filter screen 3 remains stationary and is in a stable state of filtering sewage. During the long-term filtration process, the filtered impurities accumulate below the first filter screen 3, and some impurities will naturally fall to the vicinity of the pressure plate 15.

[0041] During the rotation of the reciprocating screw 14, the pressure plate 15 moves up and down;

[0042] When the pressure plate 15 moves upward, it compresses the sewage above, forcing the first one-way valve 16 to open. At this time, a drainage space is created at the position of the first one-way valve 16, which allows impurities near the pressure plate 15 to be sucked into the first one-way valve 16 and enter the space between the transfer box 4 and the bottom wall of the pressure plate 15, reducing the impurity content in the box 1 and ensuring the effectiveness of the filtration effect of the first filter screen 3.

[0043] When the pressure plate 15 moves down, the water below the pressure plate 15 is squeezed. At this time, the water in the transfer box 4 is squeezed and flows into the collection box 9 along the lower horizontal pipe 17, which realizes the timely removal of impurities from the transfer box 4 and ensures that the space between the transfer box 4 and the bottom wall of the pressure plate 15 can effectively absorb impurities as the pressure plate 15 moves up and down again.

[0044] Furthermore, during the rotation of the reciprocating screw 14, the mounting rod 5 moves up and down with the rotation of the reciprocating screw 14. During the upward movement of the mounting rod 5, under the action of the spring 20, the push rod 19 extending from the mounting groove 18 first impacts the first filter screen 3. Then, under the reaction force of the impact, the push rod 19 retracts into the mounting groove 18. Since the depth of the mounting groove 18 is greater than the length of the push rod 19, when the top of the push rod 19 retracts into the mounting rod 5, the push rod 19 has not yet reached its lowest position. At this time, the push rod 19 continues to move downward and disengages from the first filter screen 3. When the first filter screen 3 is touched, the mounting rod 5 continues to move upward, so that the top of the mounting rod 5 can strike the first filter screen 3 again. Then the first filter screen 3 moves upward together with the moving mounting rod 5, and the elastic element 34 is squeezed. When the mounting rod 5 moves downward, the mounting rod 5 quickly disengages from the first filter screen 3. At this time, the elastic element 34 returns to its original state and pushes the first filter screen 3 downward, so that the first filter screen 3 can strike the limiting block 33. At this time, the first filter screen 3 shakes again, thereby increasing the number of shaking times of the first filter screen 3 to improve the cleaning effect of impurities on the surface of the first filter screen 3.

[0045] The upward-moving scraper 8 will contact the impurities suspended below the first filter screen 3 and move them together, thereby filtering out the water under the action of the second filter screen 23. At this time, the impurities move along the surface of the second filter screen 23 in a direction away from the mounting rod 5, and finally the impurities are pushed by the scraper 8 and come into contact with the inner wall of the box 1. When the first magnet 12 and the second magnet 13 approach each other, under the action of repulsion, the sieve plate 11 rotates and disengages from the upper horizontal tube 10, thereby allowing the impurities on the surface of the second sieve plate 11 to be thrown into the collection box 9 under the action of centrifugal force, further reducing the impurity content in the box 1.

[0046] When the first filter screen 3 contacts the top wall inside the housing 1, the spring 20 is compressed. At this time, the scraper 8 will contact the bottom wall of the first filter screen 3 for a period of time and scrape the bottom wall of the first filter screen 3, thereby improving the cleaning effect of the first filter screen 3. Compared with scraping directly on the surface of the first filter screen 3, it plays a role in preventing a large number of impurities from being squeezed into the holes on the first filter screen 3 by the scraper 8.

[0047] like Figure 2 As shown, sleeves 24 are evenly inserted on the top wall of the box 1. Elastic strips 25 are provided inside the sleeves 24, and impact rods 26 are fixedly provided on the elastic strips 25.

[0048] By adopting the above technical solution, at the moment when the first filter screen 3 moves upward to its maximum extent, the first filter screen 3 applies an upward impact force to the impact rod 26. Therefore, under the action of the reaction force of the impact force, the impurities on the bottom wall of the first filter screen 3 are subjected to a downward impact force, thereby shaking off some of the impurities stuck on the bottom wall of the first filter screen 3. Furthermore, under the action of the elastic strip 25 and inertia, the impact rod 26 will vibrate for a period of time, thus continuously applying an impact force to the first filter screen, thereby improving the cleaning effect on the bottom wall of the first filter screen 3.

[0049] like Figure 4 As shown, the bottom wall of the stirring rod 6 is provided with an installation hole 27, and an elastic diaphragm 28 is fixedly installed in the installation hole 27. A drain valve 29 is embedded in the diaphragm 28, and a water inlet valve 30 is embedded in the top wall of the installation hole 27.

[0050] By adopting the above technical solution, when the mounting rod 5 moves upward to its maximum extent, the mounting rod 5 is subjected to an impact force, which causes the water inlet valve 30 to drive the elastic diaphragm 28 to shake. At this time, the water in the mounting hole 27 is discharged downward, which can exert a downward impact force on the impurities in the vortex, accelerate the downward movement speed of the impurities, and ensure that the diaphragm 28 can continue to work under the action of the water inlet valve 30.

[0051] like Figure 4 As shown, an elastic membrane 31 is fixedly installed between the side wall of the pressure plate 15 and the inner side wall of the transfer box 4.

[0052] By adopting the above technical solution, the diameter of the pressure plate 15 can be reduced under the action of the elastic membrane 31, so that the pressure plate 15 does not need to directly contact the inner wall of the transfer box 4, which ensures that the pressure plate 15 can move smoothly. Furthermore, under the action of the elastic membrane 31, the upper and lower parts of the pressure plate 15 can be separated, which prevents impurities in the space below the pressure plate 15 from re-entering the box 1.

[0053] like Figure 2As shown, there are multiple water inlet pipes 2, which are evenly inserted into the bottom wall of the box body 1, and the inner side wall of the box body 1 is evenly provided with baffle rods 32.

[0054] By adopting the above technical solution, under the condition that the total water inflow rate remains unchanged, the drainage volume in each water inlet pipe 2 can be reduced by setting multiple water inlet pipes 2, thereby reducing the impact force and preventing impurities in the transfer box 4 from being sucked into the vortex. When the wastewater is discharged from the water inlet pipe 2, the water flow directly impacts the turbulence bar 32, thereby changing the flow direction of the water flow and reducing the impact force of the water flow on the first filter screen 3, which reduces the amount of impurities stuck in the holes of the first filter screen 3.

[0055] Example 2:

[0056] like Figure 7 As shown, a second one-way valve 22 is embedded in the lower horizontal tube 17.

[0057] By adopting the above technical solution, when the pressure plate 15 moves upward, the transfer box 4 can generate negative pressure under the action of the second one-way valve 22, causing the first one-way valve 16 to be opened under pressure and suck impurities into the transfer box 4.

[0058] Usage: The motor 7 drives the mounting rod 5 to rotate through the reciprocating screw 14, thereby generating a vortex in the space below the first filter screen 3 through the mounting rod 5 and the stirring rod 6. The generated vortex sucks in the impurities located below the first filter screen 3 in the box 1, thereby reducing the amount of impurities attached to the bottom wall of the first filter screen 3. Furthermore, under the action of the vortex, the impurities attached to the bottom wall of the first filter screen 3 are attracted downward.

[0059] During normal operation, wastewater is continuously pumped into the tank 1. At this time, the water pressure inside the tank 1 is relatively high, pushing the first filter screen 3 upwards and simultaneously filtering the wastewater. However, under the action of the elastic element 34, the upward thrust is balanced, and the first filter screen 3 remains stationary and in a stable state of filtering wastewater. During the long-term filtration process, filtered impurities accumulate below the first filter screen 3, and some impurities naturally fall to the vicinity of the pressure plate 15. During the rotation of the reciprocating screw 14, the pressure plate 15 moves up and down. When the pressure plate 15 moves upwards, it compresses the wastewater above, forcing the first one-way valve 16 to open. At this time, a drainage space is created at the position of the first one-way valve 16, which allows impurities near the pressure plate 15 to be sucked into the first one-way valve 16 and enter the space between the transfer box 4 and the bottom wall of the pressure plate 15, reducing the impurity content in the box 1 and ensuring the effectiveness of the filtration effect of the first filter screen 3. When the pressure plate 15 moves down, the water below the pressure plate 15 is squeezed. At this time, the water in the transfer box 4 is squeezed and flows along the lower horizontal pipe 17 into the collection box 9, achieving the effect of timely removal of impurities from the transfer box 4, ensuring that the space between the transfer box 4 and the bottom wall of the pressure plate 15 can effectively absorb impurities as the pressure plate 15 moves up and down again.

[0060] Additionally, during the rotation of the reciprocating screw 14, the mounting rod 5 moves up and down with the rotation of the reciprocating screw 14. During the upward movement of the mounting rod 5, under the action of the spring 20, the push rod 19 extending from the mounting groove 18 first impacts the first filter screen 3. Then, under the reaction force of the impact, the push rod 19 retracts into the mounting groove 18. Since the depth of the mounting groove 18 is greater than the length of the push rod 19, when the top of the push rod 19 retracts into the mounting rod 5, the push rod 19 has not yet reached its lowest position. At this time, the push rod 19 continues to move downward and disengages from the first filter screen 3. The mounting rod 5 then continues to move upward, allowing it to impact the first filter screen 3 again through its top. The first filter screen 3 then moves upward along with the upward-moving mounting rod 5, and the elastic element 34 is compressed. When the mounting rod 5 moves downward, the mounting rod 5 quickly impacts the first filter screen 3. When filter screen 3 disengages from contact, elastic element 34 returns to its original position and pushes the first filter screen 3 downward, causing it to impact the limiting block 33. The first filter screen 3 then vibrates again. Under the action of elastic membrane 31, the diameter of pressure plate 15 is reduced, thus eliminating the need for pressure plate 15 to directly contact the inner wall of transfer box 4. This ensures smooth movement of pressure plate 15. Furthermore, elastic membrane 31 separates the area above and below pressure plate 15, preventing impurities in the space below pressure plate 15 from re-entering the box 1. When mounting rod 5 moves upward to its maximum extent, it experiences an impact force, causing the inlet valve 30 to vibrate the elastic diaphragm 28. Water in mounting hole 27 is discharged downward, applying a downward impact force to impurities in the vortex and accelerating their downward movement.

[0061] The scraper 8 will contact the impurities suspended below the first filter screen 3 and move them together, thereby filtering out the water under the action of the second filter screen 23. At this time, the impurities move along the surface of the second filter screen 23 away from the mounting rod 5, and finally the impurities are pushed by the scraper 8 and come into contact with the inner wall of the box 1. When the first magnet 12 and the second magnet 13 approach each other, under the action of repulsion, the screen plate 11 rotates and disengages from the upper horizontal tube 10, so that the impurities on the surface of the second screen plate 11 are thrown into the collection box 9 under the action of centrifugal force. When the first filter screen 3 contacts the inner top wall of the box 1, the spring 20 is squeezed, and at this time the scraper 8 will have a period of time The scraper 8 contacts and scrapes the bottom wall of the first filter screen 3, thereby improving the cleaning effect of the first filter screen 3. Compared with scraping the surface of the first filter screen 3 directly, it prevents a large number of impurities from being squeezed into the holes of the first filter screen 3. With the total water inflow rate remaining constant, the drainage volume in each water inlet pipe 2 can be reduced by setting multiple water inlet pipes 2, thereby reducing the impact force and preventing impurities in the transfer box 4 from being sucked into the vortex. When the wastewater is discharged from the water inlet pipe 2, the water flow directly impacts the baffle rod 32, thereby changing the flow direction of the water flow and reducing the impact force of the water flow on the first filter screen 3.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
