Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of non-woven fabric processing equipment, in particular to a non-woven fabric processing water recycling device. BACKGROUND

[0002] Non-woven fabric is a material made of ordered or disordered arranged fibers. In the production process of non-woven fabric, water flow is used for hydroentanglement to add the required mesh to the non-woven fabric. In order to save water resources, the water flow used for hydroentanglement needs to be recycled, but during the hydroentanglement process, part of the fiber yarns are easily washed into the water flow, which causes the fiber yarns to easily block the water circulation system, so that the production is often delayed due to frequent maintenance and cleaning.

The device can effectively remove impurity particles and non-woven fabric fiber yarns in sewage through the cooperation of the cleaner and the stirring paddle, and can also quickly purify the sewage through the reaction between the sewage and the water purifying agent in the treatment cavity.

[0004] The above-mentioned water recycling device has the following problems in use. A plurality of cleaning boxes are arranged in the treatment tank, and filter holes with different hole diameters are arranged on both sides of the cleaning boxes.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0033] Please refer to Figures 1-10 The present application provides a technical solution: a non-woven fabric processing water recycling device, comprising a support base 1 and a processing box 2 connected to the top of the support base 1, a stirring rod 3 is rotatably connected in the processing box 2, a plurality of telescopic plates 402 are slidably connected to the stirring rod 3, the plurality of telescopic plates 402 are distributed in a circular array around the central axis of the stirring rod 3, the other end of the telescopic plate 402 is connected to a cleaning box 401, a connecting shaft 403 is rotatably connected in the stirring rod 3, and an abutting convex plate 404 is connected to the connecting shaft 403, wherein

[0034] When the connecting shaft 403 rotates, the abutting convex plate 404 rotates synchronously and abuts against the plurality of telescopic plates 402 in turn, so that the cleaning box 401 performs intermittent telescopic motion, the telescopic plate 402 extending to one side in the stirring rod 3 is connected with a first reset spring 405, the other end of the first reset spring 405 is connected to the inner wall of the stirring rod 3, one side of the processing box 2 is connected with a second servo motor 15 for driving the stirring rod 3 to rotate, and the processing box 2 is further provided with a driving member for driving the connecting shaft 403 to rotate.

[0035] It should be noted that one side of the stirring rod 3 extending to the outside of the processing box 2 is connected with a first sprocket, the driving end of the second servo motor 15 is connected with a second sprocket, and a chain is engaged and connected between the first sprocket and the second sprocket.

[0036] In implementation, first, the wastewater to be treated and the purifying agent are introduced into the treatment tank 2 at the same time, the second servo motor 15 is started, and the output power drives the stirring rod 3 to rotate in the treatment tank 2. At the same time, the driving member works to drive the connecting shaft 403 to rotate. The abutting lug 404 on the connecting shaft 403 rotates, and the abutting lug 404 will abut the plurality of expansion plates 402 arranged in the circumferential direction on the stirring rod 3 in turn. When the abutting lug 404 extrudes the expansion plate 402, the expansion plate 402 is retracted into the stirring rod 3 against the elastic force of the first return spring 405, and further drives the cleaning box 401 connected to the other end of the expansion plate 402 to retract inwardly; when the abutting lug 404 leaves the expansion plate 402, the first return spring 405 releases the elastic force to push the expansion plate 402 to drive the cleaning box 401 to extend outwardly, thereby realizing the intermittent expansion and contraction of the cleaning box 401. During the rotation of the stirring rod 3, when the cleaning box 401 extends, it can contact the impurities in the treatment tank 2 in a larger range and collect the impurities into the cleaning box 401 for filtration; when the cleaning box 401 retracts, it will stir the water flow in the treatment tank 2 to accelerate the mixing of the impurities and the purifying agent. The intermittent expansion and contraction of the cleaning box 401, on the one hand, expands the effective range of stirring, so that the purifying agent and the impurities in the sewage can be more fully mixed, and the efficiency of the purification reaction is improved; on the other hand, the range of collection and filtration of the impurities is increased, the impurity residues are reduced, and the purification effect of the sewage is improved.

[0037] Referring to Figures 1-10 , the driving member includes a fixed disc connected to one end of the stirring rod 3, the fixed disc is rotationally connected with a connecting disc 501, the connecting disc 501 is integrally formed with a plurality of teeth, the plurality of teeth are distributed at equal intervals along the inner circumferential length of the connecting disc 501, and together constitute a gear ring member, the connecting disc 501 is connected with a transmission gear 502, one end of the connecting shaft 403 extends into the connecting disc 501 and is connected with a driving gear 503, the driving gear 503 is meshed with the gear ring member and the transmission gear 502, the fixed disc is connected with a first servo motor 504, the driving end of the first servo motor 504 is connected with a synchronous wheel 505, and the connecting disc 501 and the synchronous wheel 505 are transmissionally connected with a synchronous belt 506.

[0038] It should be noted that the transmission gear 502 is a half gear with teeth occupying half of the circumference.

[0039] In implementation, the first servo motor 504 is started to drive the synchronous wheel 505 to rotate the connecting disc 501, and then the tooth ring on the connecting disc 501 is engaged with the driving gear 503 to drive the connecting shaft 403 to rotate counterclockwise. With the rotation of the connecting disc 501, when the tooth ring is not engaged with the driving gear 503, the transmission gear 502 is engaged with the driving gear 503 again to drive the connecting shaft 403 to rotate clockwise. This arrangement makes the connecting shaft 403 drive the abutting lug 404 to rotate clockwise and counterclockwise alternately, so that the cleaning tank 401 is intermittently expanded and contracted irregularly. This arrangement can further avoid the occurrence of stirring dead angle, so that the sewage and impurities in each area of the treatment tank 2 can be more uniformly stirred, collected and filtered, and the purification effect is effectively improved.

[0040] Referring to Figures 1-10 , a plurality of filter meshes are integrally formed on the two sides of the cleaning tank 401, and the diameters of the filter meshes on the two sides are different. The first adjusting filter plate 601 and the second adjusting filter plate 602 are symmetrically arranged in the cleaning tank 401, and both the first adjusting filter plate 601 and the second adjusting filter plate 602 can vertically slide along the length direction of the cleaning tank 401. The lifting member is arranged on the cleaning tank 401 to drive the first adjusting filter plate 601 and the second adjusting filter plate 602 to vertically move.

[0041] In implementation, the lifting member works to drive the first adjusting filter plate 601 and the second adjusting filter plate 602 to vertically and synchronously slide along the length direction in the cleaning tank 401. The filter meshes with different diameters are arranged on the two sides of the cleaning tank 401. When the first adjusting filter plate 601 and the second adjusting filter plate 602 synchronously slide, the size and combination mode of the filtering area in the cleaning tank 401 are changed. For example, when smaller impurities need to be filtered, the first adjusting filter plate 601 and the second adjusting filter plate 602 are slid upward to make the filter meshes with smaller diameters participate in filtering more; when larger impurities need to be filtered, the first adjusting filter plate 601 and the second adjusting filter plate 602 are slid downward to increase the filtering range of the filter meshes with larger diameters. This arrangement can conveniently and quickly adjust the filtering capacity of the cleaning tank 401 according to the actual size of the impurity particles in the sewage.

[0042] Referring to Figures 1-10 , the lifting member comprises a vertical plate connected to one side of the cleaning tank 401. The vertical plate is connected with the first mounting frame 603. The first mounting frame 603 is connected with the electromagnet 604. One side of the electromagnet 604 is connected with the tension spring. The other end of the tension spring is connected with the sliding seat 605. The sliding seat 605 is rotatably connected with the connecting plate 606. Both ends of the connecting plate 606 are rotatably connected with the connecting blocks 607. The other ends of the two connecting blocks 607 are respectively connected with the first adjusting filter plate 601 and the second adjusting filter plate 602.

[0043] In specific implementation, when the electromagnet 604 is powered, a magnetic force is generated to attract the sliding seat 605 to move towards the electromagnet 604, compressing the tension spring. The movement of the sliding seat 605 drives the movement of the connecting plate 606, and the connecting blocks 607 at both ends of the connecting plate 606 pull the first adjusting filter plate 601 and the second adjusting filter plate 602 to move upwards synchronously. When the electromagnet 604 is powered off, the sliding seat 605 moves reversely under the elastic force of the tension spring, driving the first adjusting filter plate 601 and the second adjusting filter plate 602 to move downwards synchronously, thereby realizing the synchronous automatic control of the first adjusting filter plate 601 and the second adjusting filter plate 602.

[0044] Referring to Figures 1-10 , two groups of manual adjusting members are connected to the vertical plate, including two second mounting frames 801 connected to the vertical plate, a drive gear 802 rotatably connected in the second mounting frame 801, a driven rack 803 meshingly connected to the drive gear 802, the driven rack 803 located below the connecting plate 606, and a drive rod 804 rotatably connected in the second mounting frame 801 and fixedly connected with the drive gear 802.

[0045] In specific implementation, the drive rod 804 is rotated to drive the drive gear 802 fixedly connected therewith to rotate in the second mounting frame 801. The drive gear 802 meshes with the driven rack 803 to drive the driven rack 803 to move up and down in the second mounting frame 801. Since the driven rack 803 is located below the connecting plate 606, the movement of the driven rack 803 can push the connecting plate 606 to move up and down, thereby driving the connecting blocks 607 to realize the individual control of the vertical sliding distance of the first adjusting filter plate 601 and the second adjusting filter plate 602. When it is needed to individually adjust the first adjusting filter plate 601, the drive rod 804 on one side is operated; when it is needed to individually adjust the second adjusting filter plate 602, the drive rod 804 on the other side is operated, thereby providing the function of manually individually or simultaneously adjusting the vertical sliding distance of the first adjusting filter plate 601 and the second adjusting filter plate 602, and widening the range of filter adjustment. The operator can flexibly select to individually adjust a single filter plate or simultaneously adjust two filter plates according to the specific situation of sewage impurities.

[0046] Referring to Figures 1-10 , a fixed frame 1001 is connected to the outer surface of the second mounting frame 801, one end of the drive rod 804 extends into the fixed frame 1001 and is connected with a limiting disc 1002, a threaded rod 1004 is threadedly connected to the fixed frame 1001, the other end of the threaded rod 1004 is rotatably connected with a limiting member 1003, and the limiting member 1003 is used to limit the limiting disc 1002.

[0047] In specific implementation, when the driving rod 804 is manually adjusted and the positions of the first adjusting filter plate 601 and the second adjusting filter plate 602 are determined, the threaded rod 1004 is rotated. The threaded rod 1004 is threadedly connected with the fixed frame 1001, and the limiting piece 1003 rotatably connected at the other end of the threaded rod 1004 is close to or away from the limiting disc 1002 along with the rotation of the threaded rod 1004. When the limiting piece 1003 abuts against the limiting disc 1002, the rotation of the limiting disc 1002 is limited, and the rotation of the driving rod 804 is limited, so that the positions of the first adjusting filter plate 601 and the second adjusting filter plate 602 are fixed.

[0048] Referring to Figures 1-10 The second mounting frame 801 is slidably connected with a guide rod 9, and the other end of the guide rod 9 is connected with the driven rack 803.

[0049] In specific implementation, when the driving gear 802 drives the driven rack 803 to move up and down, the guide rod 9 slides along the fixed track in the second mounting frame 801 to provide guidance for the movement of the driven rack 803. This ensures the stability and accuracy of the movement of the driven rack 803.

[0050] Referring to Figures 1-10 One side of the limiting piece 1003 is connected with a limiting rod 11, and the limiting rod 11 is slidably connected with the fixed frame 1001.

[0051] In specific implementation, the limiting rod 11 connected with one side of the limiting piece 1003 slides on the fixed frame 1001. When the limiting piece 1003 is close to or away from the limiting disc 1002 by rotating the threaded rod 1004, the limiting rod 11 slides in the sliding groove on the fixed frame 1001 to provide guidance for the movement of the limiting piece 1003.

[0052] Referring to Figures 1-10 A feeding screen 12 is arranged above the feeding port of the treatment box 2, the bottom corners of the feeding screen 12 are connected with second return springs 13, the other ends of the second return springs 13 are connected with the top of the treatment box 2, and the other side of the feeding screen 12 is connected with a vibration motor 14.

[0053] In specific implementation, the vibration motor 14 generates vibration after being started. The vibration is transmitted through the feeding screen 12, so that the feeding screen 12 vibrates up and down under the action of the second return springs 13. The sewage entering the treatment box 2 first passes through the vibrating feeding screen 12, and the feeding screen 12 can preliminarily screen the larger particles in the sewage. The larger particles are intercepted on the feeding screen 12, and the smaller particles of the sewage pass through the screen and enter the treatment box 2.

[0054] Referring to Figures 1-10 A secondary filtration barrel 7 is connected with the supporting base 1, a plurality of filter plates are inserted into the secondary filtration barrel 7, and the secondary filtration barrel 7 is located below the discharge end of the treatment box 2.

[0055] In actual implementation, the sewage treated by the treatment box 2 flows out from the discharge end and falls into the secondary filtering barrel 7. The plurality of filtering plates inserted in the secondary filtering barrel 7 filter the sewage again. The sewage passes through the plurality of filtering plates in sequence, and different filtering plates further remove the residual impurities in the sewage, including the fine impurities and fiber filaments that are not completely filtered out by the treatment box 2, according to the aperture size and filtering characteristics of the filtering plates. The water quality is further improved after the secondary filtration, and the requirements of the non-woven fabric processing water recycling can be better met.

[0056] Working principle: The wastewater in the non-woven fabric production process flows into the feeding screen 12, and the vibration motor 14 is started to make the feeding screen 12 vibrate under the action of the second return spring 13. This vibration makes the feeding screen 12 preliminarily screen the larger particle impurities in the wastewater, prevents the larger particle impurities from entering the treatment box 2 to damage the internal components, and avoids the accumulation of impurities at the feeding port to ensure that the wastewater smoothly flows into the treatment box 2.

[0057] After the wastewater enters the treatment box 2, the second servo motor 15 drives the stirring rod 3 to rotate. The stirring rod 3 rotates to drive the water flow, so that the wastewater and the water purification agent are fully mixed to accelerate the purification reaction. The driving member drives the connecting shaft 403 to rotate, and the abutting lugs 404 on the connecting shaft 403 rotate accordingly. The abutting lugs 404 abut the extension plates 402 in sequence, so that the extension plates 402 overcome the elastic force of the first return springs 405 and intermittently drive the cleaning box 401 to extend and retract. When the cleaning box 401 extends, the collection range is expanded to suck more impurities; when the cleaning box 401 retracts, the water flow is stirred to promote the mixing of impurities and the purification agent. The driving member can control the connecting shaft 403 to rotate forward and backward, so that the cleaning box 401 extends and retracts irregularly to avoid stirring dead angles.

[0058] According to the impurity condition of the wastewater, the first adjusting filter plate 601 and the second adjusting filter plate 602 in the cleaning box 401 can be adjusted in the vertical position by controlling the electromagnet 604 or manually rotating the driving rod 804. When the electromagnet 604 is powered on, the sliding seat 605 is attracted to compress the tension spring, the connecting plate 606 and the connecting block 607 are driven to move the filter plate upward; when the electromagnet 604 is powered off, the tension spring pushes the sliding seat 605 to move the filter plate downward. When manually adjusting, rotating the driving rod 804 drives the driving gear 802 to move the driven rack 803 to push the connecting plate 606 to adjust the position of the filter plate. By adjusting the filter plate, the filtering area and aperture combination in the cleaning box 401 can be flexibly changed to adapt to the filtering requirements of impurities of different sizes.

[0059] The wastewater treated by the treatment box 2 flows into the secondary filtering barrel 7 from the discharge end. The plurality of filtering plates in the secondary filtering barrel 7 filter the wastewater again to further remove the residual fine impurities and fiber filaments, improve the water quality, and make the water quality more meet the requirements of the non-woven fabric processing water recycling. The water after the secondary filtration can be reused in the spunlace processing link of the non-woven fabric production to realize the recycling of water resources.
