Description

Technical Field

[0001] The present invention relates to the technical field of non-woven fabric processing devices, and particularly relates to a water circulation utilization device for vehicle non-woven fabric processing. Background Art

[0002] Vehicle non-woven fabric is a non-woven fabric material used for manufacturing automotive interiors and related components. Usually, spunlace technology is used to produce non-woven fabrics. During the processing of non-woven fabrics, a large amount of water is required. The wastewater generated during processing contains a large amount of impurities and fiber filaments. Direct discharge not only causes waste of water but also easily pollutes water bodies. In order to save water resources, a water circulation utilization device is needed to purify and recycle the wastewater generated during the processing of non-woven fabrics. However, the impurities and fiber filaments in the wastewater easily clog the circulation device. Therefore, it is necessary to perform maintenance and cleaning frequently, which increases the workload of the staff and affects the production efficiency.

[0003] In the prior art, a rotatable cleaner is used to filter the wastewater in the treatment tank, and the impurities are collected in the cleaner. Finally, by opening the cover on the treatment tank, the staff cleans the treatment tank and the cleaner. In this way, the wastewater generated during the processing of non-woven fabrics is not cooled. Since the temperature of the wastewater generated during the processing of non-woven fabrics 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 it is still necessary to stop the machine to clean the treatment tank, which increases the workload of the staff and reduces the production efficiency; a multi-layer filtration structure is used to filter the wastewater. The impurities and fibers filtered out from the wastewater easily clog the filtration structure, affecting the permeability of the filtration structure and reducing the continuous treatment ability of the filtration structure for the wastewater and the continuous water supply ability of the circulation device to the outside. Summary of the Invention

[0022] Preferably, a controller is installed on the frame body. The controller is electrically connected to the adjusting motor and the two three-way solenoid valves and is used to control the working states of the three.

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

[0024] 1. By setting a wastewater tank in the present invention, the wastewater generated in the non-woven fabric processing process is temporarily stored; by setting a water replenishing pipe passing through the wastewater tank, the water consumption in the non-woven fabric processing process is replenished, and at the same time, the temperature of the wastewater introduced into the treatment tank is reduced, which is suitable for the flocculant to flocculate the wastewater, and the temperature of the external cold water is increased, reducing the energy consumption for heating the cold water subsequently, and facilitating the rapid reduction of the temperature of the branch pipes that need to be descaled subsequently, assisting the descaling operation; by setting a treatment tank and a filtering mechanism inside it, the impurities and flocs combined with the flocculant in the wastewater are quickly treated; by setting a liquid outlet pipe and a storage tank, a part of the treated wastewater in the treatment tank is introduced into the storage tank through the liquid outlet pipe. According to the principle of the communicating vessel, it is convenient to control the amount of wastewater introduced, and a part of the wastewater is retained in the treatment tank, so that the new wastewater is mixed with the retained wastewater, reducing the total amount of impurities in the wastewater in the treatment tank, improving the flocculation treatment efficiency of the flocculant for the wastewater, reducing the consumption of the flocculant, and improving the continuous treatment ability of the wastewater and the continuous water supply ability to the outside; finally, by setting 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 use, completing the recycling of water.

[0025] 2. The present invention drives the filter to rotate in the treatment tank by setting up a filtering mechanism and driving components. The filter salvages and filters the flocs in the treatment tank. Under the action of its own gravity, the flocs move downward along the filter and fall to the bottom of the treatment tank, and are finally discharged from the treatment tank by the slag discharging component. The output end of the driving motor can rotate bidirectionally, so that the wastewater can pass through the filter plate forward and backward, forming a backwashing effect on the mesh holes of the filter plate, further ensuring the permeability of the filter plate, increasing the working cycle of the filter plate, eliminating the need for frequent disassembly and cleaning, and reducing the workload of the staff. At the same time, by using the resistance of the wastewater in the treatment tank to the scraping component during rotation, the angle of the scraper is controlled by the rotating 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, ensuring the permeability of the filter plate, eliminating the need for additional driving equipment, reducing costs, and through the setting of the electromagnet, facilitating the scraping component on the water-facing surface to drive the scraping component on the back-facing surface to move up and down synchronously, completing the double-sided scraping and cleaning of the filter plate.

[0026] 3. The present invention sets up guide wheels and bumps. When the guide wheels move to the top and bottom of the sliding groove along with the sliding frame and rotate with the driving shaft, the guide wheels continuously roll over the bumps, causing the elastic scraper on the guide wheels to continuously vibrate the filter plate, 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 tank for subsequent treatment.

[0027] 4. The present invention sets up a heating and descaling component. The rotatable mounting plate and the heater thereon can heat the two heating chambers in the housing synchronously or separately. During synchronous heating, hot water circulation and transportation are completed. During separate heating, the temperature in the unheated heating chamber decreases, the shape memory alloy wire in the branch pipe deforms, pulling the corrugated membrane to deform, so that the scale attached to the corrugated membrane breaks and is remixed into the water, and then enters the connecting pipe through the return pipe and is finally filtered and discharged by the filtering mechanism in the treatment tank. The branch pipe in the heated heating chamber maintains the hot water circulation and transportation effect to ensure continuous water supply to the outside. There is no need to shut down the heater during descaling, only need to appropriately reduce the power of the heater and then restore the power of the heater after descaling, thereby reducing the thermal shock on the heater and reducing the wear on the heater.

Specific embodiments

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

[0038] Refer to Figure 1 and Figure 2 , a water circulation utilization device for vehicle non-woven fabric processing, including a frame body 1, further including:

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

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

[0041] The treatment tank 4 is connected to a chemical addition pipe 5 at the top, and a connecting pipe 3 is connected between the bottom of the treatment tank 4 and the bottom of the wastewater tank 2.

[0042] The chemical addition pipe 5 is used to add flocculants into the treatment tank 4. For the wastewater generated during the processing of non-woven fabrics, a combination of polyferric sulfate and organic polymer flocculants is used. Polyferric sulfate can effectively remove some suspended solids, 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 already aggregated small flocs, non-woven fabric fibers, and dissolved organic matter, enabling them to form large flocs, thus strengthening the flocculation effect through the combination of the two.

[0043] Refer to Figures 3 - 6 , the treatment tank 4 is installed on the frame 1 and is connected with a filtering mechanism. The filtering mechanism includes a driving component connected to the top of the treatment tank 4. The output end of the driving component penetrates into the treatment tank 4, and is connected with a plurality of filters. The bottom of the treatment tank 4 is connected with a slag discharging component.

[0044] The driving component includes a driving motor 6 installed on the top of the treatment tank 4. The output end of the driving motor 6 is coaxially and fixedly connected with a driving shaft 7. One end of the driving shaft 7 away from the driving motor 6 penetrates into the treatment tank 4 in a sealed manner and is connected with a plurality of filters.

[0045] The filter includes a connecting plate 8. One side of the connecting plate 8 is fixedly connected with the driving shaft 7, and the other side is fixedly connected with 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 enclose a fishing trough 11. The bottom and the side away from the filter plate 10 of the fishing trough 11 are both provided with through holes.

[0046] The driving motor 6 is a motor with a bidirectional rotatable output end, which is convenient to drive the filter to rotate forward and backward through the driving shaft 7, effectively avoiding the blockage of the mesh holes of the filter plate 10 by impurities and improving the fishing and treatment effect of impurities.

[0047] Two scraping components are connected inside the fixed frame 9. The two scraping components correspond to the two fishing troughs 11 one by one. The scraping component includes a sliding frame 13. Both sides of the fishing trough 11 are communicated with sliding grooves 12. The two ends of the sliding frame 13 are slidably connected to the two sliding grooves 12 one by one. A rotating motor 14 is installed inside the sliding frame 13. The output end of the rotating motor 14 is coaxially and fixedly connected with a rotating rod 15. A scraping plate 16 is fixedly connected to the rotating rod 15. One end of the scraping plate 16 abuts against the filter plate 10, and the other end extends towards the side opening of the fishing trough 11.

[0048] The scraping plate 16 is made of an elastic rubber plate. During the rotation of the scraping plate 16, the scraping plate 16 maintains contact with the filter plate 10, facilitating the scraping effect on the filter plate 10 when the scraping plate 16 moves up and down.

[0049] Electromagnets 17 are installed on both sliding frames 13. The magnetic field generated when the electromagnets 17 are energized magnetically attracts the iron cores in the other electromagnets 17.

[0050] A guide wheel 18 is rotatably connected to one end of the scraping plate 16 away from the filter plate 10. A plurality of bumps 19 are fixedly connected to both the inner top and inner bottom of the treatment tank 4. The height of the bumps 19 is less than the radius of the guide wheel 18. The bumps 19 are located on the rotation paths of the guide wheel 18 when the guide wheel 18 moves to the top and bottom of the sliding groove 12 along with the sliding frame 13.

[0051] When the guide wheel 18 moves to the top and bottom of the sliding groove 12 along with the sliding frame 13, along with the rotation of the drive shaft 7, the guide wheel 18 continuously rotates over the bumps 19, causing the elastic scraping plate 16 to vibrate. Thus, the scraping plate 16 continuously vibrates 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 tank 4 for subsequent treatment.

[0052] The slag discharge assembly includes a slag discharge trough body 20 connected to the bottom of the treatment tank 4. A rotatable slag discharge auger 21 is installed inside the slag discharge trough body 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 uses the existing technology. The auger blades are driven by a driving device to rotate, conveying and squeezing the flocs in the slag discharge trough body 20. After squeezing the flocs into sludge masses, the slag discharge valve 23 is opened to discharge the sludge masses from the inside of the treatment tank 4, completing the treatment of the flocs in the treatment tank 4.

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

[0055] The filtering assembly 28 uses a sand grain filtering layer and an activated carbon filtering layer in the existing technology to further remove fine fibers and odors in the wastewater.

[0056] Valves are installed on the connecting pipe 3, the chemical dosing pipe 5, and the liquid outlet pipe 26. The valves are used to control the flow of the wastewater in the connecting pipe 3, the flocculant in the chemical 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 treatment tank 4 is flush with the inner wall of the treatment tank 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 forms a cleaning effect on the filter screen 24, effectively preventing impurities from adhering to the filter screen 24 and maintaining the permeability of the filter screen 24.

[0059] Circulation mechanism, the circulation mechanism includes a circulation pump 29. The input end of the circulation pump 29 is internally connected to 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 component 28, facilitating the suction of the water above the filter component 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 component is connected to the two branch pipes. The heating and descaling component includes a housing 31 fixedly connected to the two branch pipes. The two branch pipes are arranged in parallel and both are sealed through the inside of the housing 31. A mounting plate 32 is rotatably connected inside the housing 31, and an adjusting motor 33 is installed outside. The output end of the adjusting motor 33 is hermetically penetrated into the housing 31 and is coaxially and 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 inside of the housing 31 is hermetically divided into two heating chambers 34, and the two branch pipes are hermetically penetrated through the two heating chambers 34 one by one.

[0062] Both the housing 31 and the mounting plate 32 are made of heat-insulating materials, improving the heat-insulating effect when the mounting plate 32 divides the heating chamber 34 and facilitating the rapid drop of the temperature in the unheated heating chamber 34.

[0063] A wave film 36 is fixedly and hermetically connected inside the branch pipe. The wave film 36 is elastic and internally embedded with a shape memory wire 37. The shape memory wire 37 deforms when the temperature changes.

[0064] The shape memory wire 37 is made of an existing shape memory alloy. When the temperature changes, it deforms, driving the wave film 36 to deform, so that the water scale attached to the wave film 36 is broken and incorporated into the water flow in the branch pipe, facilitating the subsequent removal of the water scale.

[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 respectively connected to the ends of the two branch pipes away from the main pipe, and three-way solenoid valves 40 are installed on both.

[0066] A controller is installed on the frame body 1. The controller is electrically connected to the adjusting motor 33 and 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. Thus, when scale cleaning is carried out in one branch pipe, the other branch pipe can maintain flow, ensuring continuous water supply through the output pipe 38 and improving the continuity of water supply through the output pipe 38.

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

[0069] When the present invention is in use, the wastewater generated during the processing of automotive non-woven fabrics first drains into the wastewater tank 2. The wastewater tank 2 is used to temporarily store the wastewater, and then the wastewater passes through the connecting pipe 3 and enters 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 replenishing pipe 41 passes through the inside of the wastewater tank 2. The external cold water exchanges heat with the wastewater across the water supply replenishing pipe 41, reducing the temperature of the wastewater, lowering the temperature of the wastewater from a relatively high temperature to a temperature suitable for the flocculant to work, ensuring the treatment effect of the subsequent flocculant on the wastewater; at the same time, increasing the temperature of the external cold water and reducing the energy consumption for heating the cold water subsequently.

[0071] After the cooled wastewater enters the treatment tank 4, the chemical adding pipe 5 works to add the flocculant into the treatment tank 4. The flocculant adopts 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 forms smaller flocs of pollutants in the wastewater; the organic polymer flocculant can make the small flocs, non-woven fabric fibers and dissolved organic matters form large flocs, strengthening the flocculation effect.

[0073] When treating the flocs in the treatment tank 4, the driving motor 6 works, and its output end drives the driving shaft 7 to rotate. The driving shaft 7 drives a plurality of filters to rotate. During the rotation process, the filters salvage and filter the flocs in the treatment tank 4, so that the flocs are collected in the salvage tank 11 on the water-facing side.

[0074] Under the action of gravity, the flocs move downward along the salvage tank 11, fall into the bottom of the treatment tank 4, and are swept into the slag discharge trough body 20 under the rotation of the sliding frame 13. The slag discharge auger 21 works to convey and extrude the flocs in the slag discharge trough body 20, and finally discharges them 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 tank 11 on the water-facing side works. Its output end drives the scraper 16 to rotate through the rotating rod 15, making the scraper 16 tilt. When the water-facing end of the scraper 16 is in a downward-tilting state, when the scraper 16 rotates in the waste water, the waste water forms a reaction force on the scraper 16, and its vertical component force pushes the scraper 16 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-tilting state, the vertical component force of the reaction force of the waste water on the scraper 16 makes the scraper 16 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 on it is energized to work, generating a magnetic field externally, magnetically attracting the iron core in the electromagnet 17 on the other side of the filter plate 10. Thus, the electromagnet 17 on the other side of the filter plate 10 drives the sliding frame 13 to move up and down synchronously, enabling the scraper 16 on the other side of the filter plate 10 to scrape the other side of the filter plate 10, completing the scraping and cleaning of both sides of the filter plate 10.

[0078] Effectively avoid that after the waste water passes through the filter plate 10, some waste water follows the movement of the filter plate 10, resulting in a weakening of the reaction force of the waste water on the scraper 16 on the back water surface and unable to effectively drive the scraper 16.

[0079] Moreover, the output end of the driving motor 6 can rotate in the reverse direction, driving multiple filters to rotate in the reverse direction through the driving shaft 7, enabling the waste water to pass through the filter plate 10 in the reverse direction, thereby forming a backwashing effect on the mesh holes of the filter plate 10, further ensuring the permeability of the filter plate 10, increasing the working cycle of the filter plate 10, eliminating the need for frequent disassembly and cleaning, and reducing the workload of the staff.

[0080] After the filtering mechanism treats the waste water in the treatment tank 4, the valve on the liquid outlet pipe 26 is opened. The treated waste water first passes through the filter net 24. After being filtered again by the filter net 24, it is introduced into the liquid storage tank 27 through the liquid outlet pipe 26. Due to the principle of the communicating vessel, it is convenient to control the amount of water introduced into the liquid storage tank 27.

[0081] Under the operation of the filtering mechanism, part of the pollutants in the wastewater inside the treatment tank 4 are discharged from the inside of the treatment tank 4 through the slag discharging assembly, 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 supplement new wastewater into the treatment tank 4. After the new wastewater is supplemented, the valve on the connecting pipe 3 is closed. At this time, the chemical adding pipe 5 adds an appropriate amount of flocculant into the treatment tank 4. Since the total amount of impurities in the wastewater in the treatment tank 4 decreases at this time, the binding efficiency of the flocculant and the impurities can be improved, and the flocculation treatment efficiency of the flocculant for the impurities in the wastewater can be improved. Thus, the addition amount of the flocculant can be correspondingly reduced, the consumption of the flocculant can be reduced, the cost can be lowered, and the treatment efficiency of the wastewater can be improved.

[0082] Meanwhile, the total amount of flocs in the treatment tank 4 is reduced, the treatment burden of the filter on the flocs in the wastewater is reduced, and the working burden of the subsequent filtering assembly 28 is reduced, its working cycle is increased, the continuous working ability of the filter and the filtering assembly 28 is further improved, the continuous treatment ability of the wastewater is enhanced, and the continuous water supply ability to the outside is ensured.

[0083] The wastewater introduced into the liquid storage tank 27 is subjected to secondary filtration treatment by the filtering assembly 28. The water above the filtering assembly 28 is the water available for circulation. The water replenishing pipe 41 replenishes water above the liquid storage tank 27 at the same time to make up for the water consumption in the non-woven fabric processing process.

[0084] The circulating pump 29 operates. Its input end sucks the water above the filtering assembly 28 in the liquid storage tank 27, and its output end introduces the water into the circulating pipe 30.

[0085] At this time, the mounting plate 32 inside the housing 31 is in a horizontal state, and the two heating chambers 34 are in a communicating state. The heater 35 operates to heat the entire inside of the housing 31 and heat both branches of the circulating pipe 30, so that the temperature of the water passing through the branches rises to reach the temperature of the water 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 the recycling of water.

[0086] During the continuous heating of the branches by the heater 35, scale is likely to be generated inside the branches. At this time, the controller operates to control the motor 33 to operate. 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 keeps operating normally, and the heated water is normally output through the output pipe 38.

[0087] The three-way solenoid valve 40 on the unheated branch pipe operates to connect the branch pipe with the return pipe 39. Since the temperature of the external cold water supplemented by the water supply pipe 41 and the filtered waste water in the liquid storage tank 27 is relatively low, the temperature in the unheated branch pipe is rapidly reduced under the circulation of the water at a relatively low temperature. After the temperature in the branch pipe is reduced, the shape memory wire 37 in the corrugated diaphragm 36 deforms due to the temperature change, pulling the corrugated diaphragm 36 to deform, so that the scale attached to the corrugated diaphragm 36 is broken, and then it merges into the water again, passes through the return pipe 39 into the connecting pipe 3, and finally is filtered and discharged by the filtering mechanism in the treatment tank 4.

[0088] After cleaning the scale in one branch pipe, the controller controls the regulating motor 33 and the two three-way solenoid valves 40 to work correspondingly, and the scale cleaning in the other branch pipe can be completed in the same way.

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

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

[0091] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
