Description

Technical Field

[0001] The present invention relates to the technical field of non-woven fabric processing devices, and in particular to a water recycling device for processing non-woven fabrics for vehicles. Background Art

[0002] Automotive non-woven fabrics are non-woven materials used in the manufacture of automotive interiors and related components. These materials are typically produced using a hydroentanglement process. This process consumes large amounts of water, and the resulting wastewater contains numerous impurities and fibers. Direct discharge not only wastes water but also easily pollutes water bodies. To conserve water resources, water recycling equipment is required to purify and recycle the wastewater generated during non-woven fabric processing. However, impurities and fibers in the wastewater can easily clog the recycling equipment, necessitating frequent maintenance and cleaning. This increases the workload for workers and impacts production efficiency.

[0003] In the prior art, a rotatable cleaner is used to filter the wastewater in the treatment tank, and impurities are collected in the cleaner. Finally, the cover on the treatment tank is opened and the staff cleans the treatment tank and the cleaner. In this method, the wastewater generated in the non-woven fabric processing process is not cooled. Since the temperature of the wastewater generated in the non-woven fabric processing process is relatively high and there are many impurities in the wastewater, it is easy to affect the treatment effect of the flocculant on the wastewater, and the treatment tank still needs to be shut down to clean, which increases the workload of the staff and reduces production efficiency. A multi-layer filter structure is used to filter the wastewater. The impurities and fibers filtered out of the wastewater are easy to clog the filter structure, affecting the permeability of the filter structure, reducing the filter structure's continuous treatment capacity for wastewater and the circulation device's ability to continuously supply water to the outside.

[0023] Compared with the prior art, the advantages of the present invention are:

[0024] 1. The present invention temporarily stores wastewater generated during the processing of non-woven fabrics by setting up a wastewater tank; by setting up a water supply pipe passing through the wastewater tank, the water consumption during the processing of non-woven fabrics is replenished, and at the same time the temperature of the wastewater entering the processing tank is reduced, a suitable flocculant is used to flocculate the wastewater, and the temperature of the external cold water is increased, thereby reducing the energy consumption of subsequent heating of the cold water, and conveniently and quickly reducing the temperature of the branch pipe that needs to be descaled later, thereby assisting the descaling operation; by setting up the processing tank and the filtering mechanism inside the processing tank, the flocs formed by the combination of impurities and flocculants in the wastewater are quickly processed; by setting up a liquid outlet pipe and a liquid storage tank, The liquid outlet pipe passes part of the treated wastewater in the treatment box into the liquid storage tank. Through the principle of communicating vessels, the amount of water entering the wastewater is conveniently controlled, and part of the wastewater is retained in the treatment box to mix the new wastewater with the retained wastewater, thereby reducing the total amount of impurities in the wastewater in the treatment box, improving the flocculation treatment efficiency of the flocculant on the wastewater, reducing the consumption of the flocculant, and improving the continuous treatment capacity of the wastewater and the continuous water supply capacity to the outside; finally, by setting up a circulation mechanism, the treated wastewater and the preheated external cold water are heated, and the heated water can be directly output for subsequent non-woven fabric processing, completing the water recycling.

[0025] 2. The present invention provides a filtering mechanism in which a driving assembly drives the filter to rotate within the treatment box. The filter salvages and filters the flocs within the treatment box. Under the action of its own gravity, the flocs move downward along the filter and fall to the bottom of the treatment box, where they are eventually discharged from the treatment box by the slag discharge assembly. The output end of the driving motor can rotate in both directions, so that wastewater can pass through the filter plate in both directions, forming a backwash effect on the mesh of the filter plate, further ensuring the permeability of the filter plate and improving the working cycle of the filter plate. Frequent disassembly and cleaning of the filter plate is unnecessary, thereby reducing the workload of the staff. At the same time, the resistance of the wastewater within the treatment box to the rotating scraper assembly is utilized to control the angle of the scraper by rotating the motor. Under the reaction force of the wastewater on the scraper, the scraper moves up and down, forming a scraping effect on the water-facing surface of the filter plate, effectively preventing flocs from adhering to the filter plate and ensuring the permeability of the filter plate. No additional driving equipment is required, thus reducing costs. Furthermore, the provision of an electromagnet facilitates the scraper assembly on the water-facing surface to drive the scraper assembly on the water-receiving surface to move up and down synchronously, completing double-sided scraping and cleaning of the filter plate.

[0026] 3. The present invention provides a guide wheel and a protrusion. When the guide wheel moves to the top and bottom of the sliding groove with the sliding frame, the guide wheel rotates continuously with the rotation of the drive shaft to press the protrusion, so that the guide wheel continuously vibrates the filter plate through the elastic scraper, further preventing impurities in the wastewater from adhering to the filter plate and maintaining the permeability of the filter plate; at the same time, it is convenient for impurities to fall to the bottom of the treatment box, making it convenient for the impurities to be processed later.

[0027] 4. The present invention provides a heating and descaling component. The rotatable mounting plate cooperates with the heater thereon to heat the two heating chambers in the outer shell synchronously or individually. During synchronous heating, hot water circulation is completed; during individual heating, the temperature in the unheated heating chamber decreases, the memory metal wire in the branch pipe is deformed, and the wave membrane is pulled to deform, so that the scale attached to the wave membrane is broken and merged into the water again, and flows into the connecting pipe along the return pipe, and is finally filtered and discharged by the filtering mechanism in the treatment box, while the branch pipe in the heated heating chamber maintains the hot water circulation effect, ensuring a continuous water supply to the outside; there is no need to shut down the heater during the descaling process, only the power of the heater needs to be reduced accordingly, and the power of the heater needs to be restored after the descaling is completed, thereby reducing the thermal shock to the heater and reducing the wear on the heater.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Reference Figure 1 and Figure 2 A water recycling device for processing non-woven fabrics for vehicles, comprising a frame 1, and further comprising:

[0039] Wastewater tank 2, wastewater tank 2 is installed on the top of the frame 1.

[0040] The wastewater tank 2 is used to temporarily collect and store wastewater generated during the processing of the automotive non-woven fabric.

[0041] The top of the treatment box 4 is connected to a dosing pipe 5 , and the bottom of the treatment box 4 is connected to a connecting pipe 3 .

[0042] The dosing pipe 5 is used to add flocculants into the treatment box 4. For the wastewater generated during the non-woven fabric processing, a combination of polyferric sulfate and organic polymer flocculants is used. Polyferric sulfate can effectively remove some suspended matter, colloids and negatively charged pollutants in the wastewater, reduce the turbidity and chemical oxygen demand of the wastewater, and form smaller flocs; the organic polymer flocculant can adsorb and bridge the aggregated small flocs, non-woven fabric fibers and soluble organic matter, so that they form large flocs. The flocculation effect is enhanced by the combination of the two.

[0043] Reference Figure 3-Figure 6 The processing box 4 is installed on the frame 1 and is connected to a filtering mechanism. The filtering mechanism includes a driving component connected to the top of the processing box 4. The output end of the driving component extends through the processing box 4 and is connected to multiple filters. The bottom of the processing box 4 is connected to a slag discharge component.

[0044] The drive assembly includes a drive motor 6 installed on the top of the processing box 4. The output end of the drive motor 6 is coaxially fixedly connected to a drive shaft 7. The end of the drive shaft 7 away from the drive motor 6 is sealed and extends into the processing box 4 and is connected to multiple filters.

[0045] The filter includes a connecting plate 8, one side of the connecting plate 8 is fixedly connected to the drive shaft 7, and the other side is fixedly connected to a fixed frame 9. A filter plate 10 is fixedly connected inside the fixed frame 9. Both sides of the filter plate 10 and the inner wall of the fixed frame 9 form a salvage groove 11. The bottom of the salvage groove 11 and the side away from the filter plate 10 are both penetrated.

[0046] The driving motor 6 adopts a motor with bidirectional rotation at the output end, which is convenient for driving the filter to rotate forward and reverse through the driving shaft 7, effectively preventing impurities from clogging the mesh of the filter plate 10 and improving the salvage effect of impurities.

[0047] Two scraping assemblies are connected to the inside of the fixed frame 9, and the two scraping assemblies correspond one-to-one to the two salvage grooves 11. The scraping assembly includes a sliding frame 13. Both sides of the salvage groove 11 are connected to the sliding grooves 12. The two ends of the sliding frame 13 are slidably connected in the two sliding grooves 12 in a one-to-one manner. A rotating motor 14 is installed in the sliding frame 13. The output end of the rotating motor 14 is coaxially fixedly connected to a rotating rod 15. A scraper 16 is fixedly connected to the rotating rod 15. One end of the scraper 16 rests on the filter plate 10, and the other end extends to the side opening of the salvage groove 11.

[0048] The scraper 16 is made of an elastic rubber plate. During the rotation of the scraper 16 , the scraper 16 maintains contact with the filter plate 10 , so that the scraper 16 can scrape the filter plate 10 when the scraper 16 moves up and down.

[0049] An electromagnet 17 is mounted on each of the two sliding frames 13 . The magnetic field generated by energizing the electromagnet 17 magnetically attracts the iron core of the other electromagnet 17 .

[0050] The scraper 16 is rotatably connected to the guide wheel 18 at one end away from the filter plate 10, and a plurality of protrusions 19 are fixedly connected to the top and bottom of the processing box 4. The height of the protrusion 19 is less than the radius of the guide wheel 18. The protrusion 19 is located on the rotation path of the guide wheel 18 when it moves to the top and bottom of the sliding groove 12 with the sliding frame 13.

[0051] When the guide wheel 18 moves to the top and bottom of the sliding groove 12 with the sliding frame 13, as the drive shaft 7 rotates, the guide wheel 18 continuously rotates to press the protrusion 19, so that the guide wheel 18 drives the elastic scraper 16 to vibrate, thereby causing the scraper 16 to continuously vibrate the filter plate 10, effectively preventing impurities in the wastewater from adhering to the filter plate 10, maintaining the permeability of the filter plate 10, and at the same time facilitating the impurities to fall to the bottom of the treatment box 4, making it convenient for the impurities to be subsequently processed.

[0052] The slag discharge assembly includes a slag discharge trough 20 connected to the bottom of the processing box 4. A rotatable slag discharge auger 21 is installed inside the slag discharge trough 20, and a slag discharge pipe 22 is connected to the bottom. A slag discharge valve 23 is installed on the slag discharge pipe 22.

[0053] The slag discharge auger 21 adopts the existing technology, and the driving device drives the auger blades to rotate, transporting and squeezing the flocs in the slag discharge trough 20. After the flocs are squeezed into sludge balls, the slag discharge valve 23 is opened to discharge the sludge balls from the interior of the treatment box 4, completing the treatment of the flocs in the treatment box 4.

[0054] Reference Figure 3 、 Figure 7 and Figure 8 , a liquid storage tank 27, a filter assembly 28 is installed inside the liquid storage tank 27, and a liquid outlet pipe 26 is connected to the bottom of the treatment tank 4, a filter screen 24 is fixedly connected to the liquid outlet pipe 26, and a water supply pipe 41 is connected to the top of the liquid storage tank 27, and the middle part of the water supply pipe 41 is sealed and passes through the interior of the wastewater tank 2.

[0055] The filter assembly 28 uses a sand filter layer and an activated carbon filter layer in the prior art to further remove fine fibers and odors in the wastewater.

[0056] Valves are installed on the connecting pipe 3 , the dosing pipe 5 and the liquid outlet pipe 26 . The valves are used to control the circulation of the wastewater in the connecting pipe 3 , the flocculant in the dosing pipe 5 and the wastewater in the liquid outlet pipe 26 .

[0057] A cleaning brush 25 is fixedly connected to the sliding frame 13 . The filter screen 24 is arc-shaped, and the side close to the inside of the processing box 4 is flush with the inner wall of the processing box 4 . The filter screen 24 is located on the rotation path of the cleaning brush 25 .

[0058] During the rotation of the sliding frame 13 , the cleaning brush 25 cleans the filter 24 , effectively preventing impurities from adhering to the filter 24 and maintaining the permeability of the filter 24 .

[0059] The circulation mechanism includes a circulation pump 29. The input end of the circulation pump 29 is connected to the inside of the liquid storage tank 27, and the output end is connected to a circulation pipe 30. A heating and descaling component is installed on the circulation pipe 30, and the output end is connected to an output pipe 38. The output end of the heating and descaling component is connected to the connecting pipe 3.

[0060] The input end of the circulation pump 29 extends into the liquid storage tank 27 and is located above the filter assembly 28, so as to facilitate the suction of water above the filter assembly 28.

[0061] The circulation pipe 30 includes a main pipe and two branch pipes connected to the main pipe. The main pipe is connected to the output end of the circulation pump 29, and the two branch pipes are connected to the same output pipe 38. The heating and descaling assembly is connected to the two branch pipes. The heating and descaling assembly includes a shell 31 fixedly connected to the two branch pipes. The two branch pipes are arranged in parallel and are both sealed and pass through the interior of the shell 31. A mounting plate 32 is rotatably connected to the interior of the shell 31, and an adjusting motor 33 is installed on the outside. The output end of the adjusting motor 33 is sealed and extends into the shell 31, and is coaxially fixedly connected to the mounting plate 32. A heater 35 is installed on the side of the mounting plate 32. When the mounting plate 32 is in a vertical state, the interior of the shell 31 is sealed and divided into two heating chambers 34. The two branch pipes are sealed and pass through the two heating chambers 34 in a one-to-one correspondence.

[0062] The housing 31 and the mounting plate 32 are both made of heat-insulating material, which improves the heat-insulating effect of the mounting plate 32 when separating the heating chamber 34 , and conveniently and quickly reduces the temperature in the unheated heating chamber 34 .

[0063] The branch pipe is sealed and fixedly connected with a fluctuation membrane 36 inside. The fluctuation membrane 36 is elastic and has a memory metal wire 37 embedded inside. The memory metal wire 37 is deformed when the temperature changes.

[0064] The memory wire 37 is made of existing memory alloy. When the temperature changes, it deforms, driving the wave membrane 36 to deform, thereby breaking up the scale attached to the wave membrane 36 and merging it into the water flow in the branch pipe, making it easier to remove the scale later.

[0065] The return pipe 39 is a three-way pipe. The two ends of the return pipe 39 away from the connecting pipe 3 are connected to the ends of the two branch pipes away from the main pipe in a one-to-one correspondence, and both ends are installed with a three-way solenoid valve 40.

[0066] A controller is installed on the frame 1 . The controller is electrically connected to the regulating motor 33 and the two three-way solenoid valves 40 and is used to control the working states of the three.

[0067] Through two branch pipes, a rotatable heater 35 and two three-way solenoid valves 40, it is convenient to control the independent flow of the two branch pipes, so that when one branch pipe is cleaning scale, the other branch pipe can maintain flow, which can ensure continuous water supply to the output pipe 38 and improve the continuity of water supply to the output pipe 38.

[0068] There is no need to shut down the heater 35 during the descaling process. Instead, the power of the heater 35 needs to be reduced accordingly and then restored after the descaling is completed, thereby reducing the thermal shock on the heater 35 and reducing the wear on the heater 35.

[0069] When the present invention is used, wastewater generated by processing the automotive nonwoven fabric is first discharged into the wastewater tank 2 , which is used to temporarily store the wastewater. The wastewater is then passed through the connecting pipe 3 into the treatment tank 4 .

[0070] Before the wastewater enters the treatment tank 4 through the connecting pipe 3, the external cold water in the water supply pipe 41 passes through the inside of the wastewater tank 2. The external cold water and the wastewater exchange heat across the water supply pipe 41, thereby reducing the temperature of the wastewater, so that the wastewater is reduced from a higher temperature to a temperature suitable for the operation of the flocculant, thereby ensuring the subsequent treatment effect of the flocculant on the wastewater; at the same time, the temperature of the external cold water is increased, thereby reducing the energy consumption of subsequent heating of the cold water.

[0071] After the cooled wastewater is passed into the treatment box 4, the dosing pipe 5 is operated to add flocculant into the treatment box 4. The flocculant is a combination of polyferric sulfate and organic polymer flocculant. When adding the flocculant, polyferric sulfate is added first, and then the organic polymer flocculant is added.

[0072] Polyferric sulfate first causes the pollutants in the wastewater to form smaller flocs; organic polymer flocculants can make small flocs, non-woven fibers and dissolved organic matter further form large flocs, thereby enhancing the flocculation effect.

[0073] When the flocs in the treatment box 4 are being treated, the drive motor 6 works, and its output end drives the drive shaft 7 to rotate, and the drive shaft 7 drives multiple filters to rotate. During the rotation process, the filters salvage and filter the flocs in the treatment box 4, so that the flocs are collected in the salvage trough 11 on the water-facing side.

[0074] Under the action of gravity, the flocs move downward along the salvage trough 11 and fall into the bottom of the processing box 4. Under the rotation of the sliding frame 13, they are swept into the slag discharge trough 20. The slag discharge auger 21 works to transport and squeeze the flocs in the slag discharge trough 20, and finally discharged through the slag discharge pipe 22.

[0075] When cleaning the filter plate 10, during the rotation of the filter, the rotating motor 14 in the salvage trough 11 on the water-facing side works, and its output end drives the scraper 16 to rotate through the rotating rod 15, so that the scraper 16 is tilted. When the water-facing end of the scraper 16 is in a downward tilted state, the scraper 16 rotates in the wastewater, and the wastewater forms a reaction force on the scraper 16, and its component force in the vertical direction pushes the scraper 16 to move downward. The scraper 16 drives the sliding frame 13 to move downward along the sliding groove 12 through the rotating rod 15 and the rotating motor 14; conversely, when the water-facing end of the scraper 16 is in an upward tilted state, the vertical component of the reaction force of the wastewater on the scraper 16 causes the scraper 16 to move upward.

[0076] During the up and down movement of the scraper 16 , the end of the scraper 16 in contact with the filter plate 10 forms a scraping effect on the water-facing surface of the filter plate 10 , effectively preventing flocs from adhering to the filter plate 10 and ensuring the permeability of the filter plate 10 .

[0077] At the same time, when the sliding frame 13 moves up and down, the electromagnet 17 thereon is energized to generate a magnetic field to the outside, magnetically attracting the iron core of the electromagnet 17 on the other side of the filter plate 10, so that the electromagnet 17 on the other side of the filter plate 10 drives the sliding frame 13 to move up and down synchronously, so that the scraper 16 on the other side of the filter plate 10 scrapes the other side of the filter plate 10, thereby completing the scraping and cleaning of both sides of the filter plate 10.

[0078] This effectively prevents the wastewater from following the movement of the filter plate 10 after passing through the filter plate 10 , which causes the reaction force of the wastewater on the scraper 16 on the back surface of the water to be weakened and unable to effectively drive the scraper 16 .

[0079] In addition, the output end of the drive motor 6 can rotate in the reverse direction, driving the multiple filters to rotate in the reverse direction through the drive shaft 7, so that the wastewater passes through the filter plate 10 in the reverse direction, thereby forming a recoil effect on the mesh of the filter plate 10, further ensuring the permeability of the filter plate 10, and improving the working cycle of the filter plate 10. There is no need for frequent disassembly and cleaning, which reduces the workload of the staff.

[0080] After the filtering mechanism treats the wastewater in the treatment box 4, the valve on the liquid outlet pipe 26 is opened, and the treated wastewater first passes through the filter screen 24, and after being filtered again by the filter screen 24, it enters the liquid storage tank 27 through the liquid outlet pipe 26. Due to the principle of communicating vessels, it is convenient to control the amount of water entering the liquid storage tank 27.

[0081] Under the operation of the filtering mechanism, part of the pollutants in the wastewater inside the treatment box 4 are discharged from the treatment box 4 through the slag discharge component, and part of the treated wastewater is introduced into the liquid storage tank 27. At this time, the valve on the connecting pipe 3 is opened to replenish new wastewater into the treatment box 4. After the new wastewater is replenished, the valve on the connecting pipe 3 is closed. At this time, the dosing pipe 5 adds an appropriate amount of flocculant to the treatment box 4. Since the total amount of impurities in the wastewater in the treatment box 4 is reduced at this time, the combination efficiency of the flocculant and the impurities can be improved, and the flocculation treatment efficiency of the flocculant on the impurities in the wastewater can be improved, thereby reducing the amount of flocculant added, reducing the consumption of flocculant, reducing costs, and improving the treatment efficiency of wastewater.

[0082] At the same time, the total amount of flocs in the treatment box 4 is reduced, the burden of the filter on processing flocs in the wastewater is reduced, and the workload of the subsequent filter component 28 is reduced, thereby increasing its working cycle, further improving the continuous working ability of the filter and the filter component 28, enhancing the continuous treatment capacity of wastewater, and ensuring the continuous water supply capacity to the outside.

[0083] The wastewater introduced into the liquid storage tank 27 is filtered again through the filter assembly 28. The water above the filter assembly 28 is the water that can be used for circulation. The water supply pipe 41 also supplies water to the top of the liquid storage tank 27 to make up for the water consumption during the non-woven fabric processing.

[0084] The circulation pump 29 works, and its input end sucks the water above the filter assembly 28 in the liquid storage tank 27, and its output end passes the water into the circulation pipe 30.

[0085] At this time, the mounting plate 32 in the shell 31 is in a horizontal state, the two heating chambers 34 are in a connected state, the heater 35 is working, the entire interior of the shell 31 is heated, and the two branches in the circulation pipe 30 are heated, so that the temperature of the water passing through the branches is increased to reach the water temperature required for subsequent non-woven fabric processing. The hot water is output through the output pipe 38, which is convenient for direct use in subsequent non-woven fabric processing and convenient for water recycling.

[0086] During the continuous heating process of the branch pipe by the heater 35, scale is easily generated inside the branch pipe. At this time, the controller works and the regulating motor 33 works under control. Its output end drives the mounting plate 32 to rotate. The mounting plate 32 rotates to a vertical state, sealing and separating the two heating chambers 34, and drives the heater 35 to rotate, so that the heater 35 only heats one heating chamber 34 and the branch pipe located in the heating chamber 34. The three-way solenoid valve 40 on the heated branch pipe maintains normal operation, and the heated water is output normally through the output pipe 38.

[0087] The three-way solenoid valve 40 on the unheated branch pipe works to connect the branch pipe with the return pipe 39. Since the temperature of the external cold water added by the water supply pipe 41 and the waste water filtered in the liquid storage tank 27 is relatively low, the temperature in the unheated branch pipe is quickly reduced under the circulation of water at a relatively low temperature. After the temperature in the branch pipe is reduced, the memory metal wire 37 in the fluctuation membrane 36 is deformed due to the temperature change, pulling the fluctuation membrane 36 to deform, thereby breaking up the scale attached to the fluctuation membrane 36 and returning it to the water, and then passing into the connecting pipe 3 along the return pipe 39, and finally being filtered and discharged by the filtering mechanism in the treatment box 4.

[0088] After the scale cleaning in one branch pipe is completed, the controller controls the regulating motor 33 and the two three-way solenoid valves 40 to perform corresponding operations, thereby completing the scale cleaning in the other branch pipe in the same manner.

[0089] After the scale cleaning is completed, the controller controls the regulating motor 33 and the two three-way solenoid valves 40 to resume normal working state.

[0090] By treating scale without stopping the machine, the continuous treatment capacity of wastewater and the continuous external water supply capacity are further improved, and the recycling treatment and utilization efficiency of wastewater are improved.

[0091] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
