Description

Technical Field

[0001] The invention relates to the technical field of water pollution control, and in particular to wastewater treatment equipment for the production of non-woven fabrics for automobiles. Background Art

[0002] Automotive non-woven fabrics are a new generation of environmentally friendly materials. They are moisture-proof, breathable, flexible, lightweight, flame-retardant, thermally insulating, non-toxic, odorless, and non-irritating. They are widely used in automobiles, such as car trunks, car seat cushions, and car ceiling sound insulation. In the production process of non-woven fabrics, a large amount of wastewater containing fiber debris, chemical additives, dyes, and organic pollutants will be generated. For example, in the production methods of spunlace, spunbond, and meltblown, chemical agents are required in subsequent processes such as dyeing, coating, and printing. The wastewater contains pollutants such as dyes and additives. In the pretreatment of raw materials, if natural fibers or recycled materials are used, wastewater will also be generated during the cleaning process.

[0003] The existing patent publication number CN119118253A discloses a flushable spunlace non-woven fabric production wastewater treatment device, which includes a wastewater treatment box, a filter plate is arranged inside the wastewater treatment box, the outer wall of the filter plate is slidably connected to the inner wall of the wastewater treatment box, a pull rope assembly is arranged on the top of the wastewater treatment box, a tilting assembly is arranged on the top of the filter plate, and a stirring assembly is arranged on the bottom of the filter plate.

[0004] In the above technical solution, during the rising process of the filter plate, the suspended matter in the wastewater can be salvaged, and when the filter plate rises to a certain height, it will touch the tilting component, causing the filter plate to tilt. The wastewater retained on the surface of the filter plate will flow rapidly downward under the action of gravity and return to the interior of the wastewater treatment tank.

[0042] See also Figure 1-8 The present invention provides a technical solution: a wastewater treatment device for the production of non-woven fabrics for automobiles, comprising a treatment tank 1, a filter barrel 5 and a storage chamber 6,

[0043] A drain pipe 501 is provided between the treatment tank 1 and the filter barrel 5. A feed expansion opening 502 is provided at the upper end of the filter barrel 5. A detachable filter screen cylinder 503 is provided inside the filter barrel 5. The filter screen cylinder 503 is connected to the feed expansion opening 502.

[0044] An injection pipe 601 is provided between the material storage chamber 6 and the treatment tank 1, and the treatment agent is injected into the material storage chamber 6 through the injection pipe 601;

[0045] A stirring mechanism is provided on the inner side of the treatment tank 1, a pair of scrapers 102 are provided on the bottom of the treatment tank 1, a solid port 103 and a liquid port 104 are provided on the lower end of the treatment tank 1, a fine screen 111 is provided at the liquid port 104 and a water outlet pipe 105 is provided on the lower side thereof, the lower end of the water outlet pipe 105 is connected to a wastewater tank, and a sealing mechanism is provided in the solid port 103.

[0046] First, the wastewater to be treated is discharged into the filter barrel 5. A feed expansion port 502 is provided at the upper end of the filter barrel 5, so as to facilitate the wastewater to enter the filter screen cylinder 503. The filter screen cylinder 503 is in the shape of a vertical cylinder, which further increases the filtering area and can perform preliminary filtering on the poured wastewater in all directions. It will not be blocked due to filtering out too many impurities at one time. The wastewater after preliminary filtering enters the treatment tank 1 through the discharge pipe 501, and a one-way valve is provided in the discharge pipe 501 to ensure that the wastewater will not flow back into the filter barrel 5 during the treatment process of the treatment tank 1. Then, the corresponding treatment agent is extracted from the storage chamber 6 and injected into the treatment tank 1 through the water pump assembly and the injection pipe 601. The treatment agent includes but is not limited to chemical agents used to treat wastewater and sewage, such as precipitants, purifiers and flocculants. Then, the wastewater and the treatment agent are stirred by a stirring mechanism. The mixture is stirred and mixed so that the treatment agent reacts fully and quickly, thereby further generating impurities such as suspended matter or precipitate. Then, the valve arranged on the outlet pipe 105 is opened so that the solid impurities are further filtered under the action of the fine screen 111, and the treated wastewater is discharged into the wastewater pool, thereby completing the treatment of the wastewater. After the wastewater in the treatment tank 1 is emptied, impurities such as suspended matter or precipitate fall to the bottom of the treatment tank 1. At this time, a pair of scrapers 102 are rotated to scrape off the solid impurities precipitated at the bottom and on the fine screen 111, and the sealing mechanism opens and releases the sealing state of the solid port 103, so that the scraper 102 finally discharges all the solid impurities from the solid port 103, thereby completing the automatic cleaning of the interior of the treatment tank 1. The operation is simple and convenient, and the wastewater treatment efficiency is improved.

[0047] The outer end and the inner end of the scraper rod 102 are fixedly connected with a triangular offset block, the middle end of a pair of scraper rods 102 is fixedly connected with a central rotating rod 106, and the lower end of the scraper rod 102 is in contact with the bottom of the processing tank 1.

[0048] Preferably, the straight surface length of the scraper rod 102 is set equal to the diameter of the solid port 103, so that during the rotation of the scraper rod 102, impurities close to the outer edge and the inner side are gathered in the middle straight surface part of the scraper rod 102 under the guidance of the triangular offset block until the scraper rod 102 moves into the solid port 103, thereby pushing all the impurities in the straight surface part into the solid port 103, thereby completing the internal impurity cleaning, and the cleaning is thorough and efficient.

[0049] The sealing mechanism includes a sealing plate 2, which is interference fit with the solid port 103. A sealing ring 201 is provided at the lower end of the solid port 103. A cover plate is fixedly connected to the lower end of the sealing plate 2, which is adapted to the sealing ring 201. A lifting mechanism is provided on the lower side of the cover plate. When sealing, the upper end surface of the sealing plate 2 is flush with the bottom surface of the processing tank 1.

[0050] Preferably, since the solid port 103 is used to clean up solid impurities such as suspended matter or sediment generated by wastewater treatment, that is, it is impossible to use components such as valves to control the discharge of the solid port 103, a sealing mechanism is provided. Specifically, the sealing plate 2 and the solid port 103 are interference fit, and the cover plate and the sealing plate 2 are arranged in a stepped shape, corresponding to the stepped shape formed by the solid port 103 and the sealing ring 201, thereby further improving the sealing performance of the solid port 103, and when the sealing plate 2 is sealed, its upper end face is flush with the bottom face of the treatment tank 1, thereby ensuring that no depression will occur to cause wastewater residue.

[0051] A base 9 is provided at the lower end of the processing tank 1, and a gear sink groove is provided at the upper end of the base 9;

[0052] The lifting mechanism includes a threaded sleeve 202, the lower end of the threaded sleeve 202 is threadedly connected to a threaded rod 203, the lower end of the threaded rod 203 is fixedly connected to a gear 1 204, one side of the gear 1 204 is meshedly connected to a gear 2 205, both the gear 1 204 and the gear 2 205 are rotatably connected in the gear sink groove, the central rotating rod 106 passes through the processing tank 1 and is rotatably connected thereto, and the upper end of the gear 2 205 is fixedly connected to the central rotating rod 106.

[0053] Preferably, the scraper rod 102 is driven to clean impurities by the rotation of the center rotating rod 106. At the same time, the center rotating rod 106 further drives gear 2 205 and gear 1 204 to rotate, and gear 1 204 drives the threaded rod 203 to rotate. The threaded sleeve 202 is driven by the threaded connection to drive the sealing plate 2 to rise and fall, thereby opening the solid port 103. In other words, while the scraper rod 102 is used to clean impurities, the solid port 103 can be opened additionally, so that the impurities being cleaned can be directly discharged from the solid port 103. The cleaning and discharge have good synchronization, and there is no need to equip an additional control program or system to control the sealing mechanism, thereby saving costs.

[0054] A closed cover 101 is provided at the lower end of the solid port 103, and the two ends of the closed cover 101 are fixedly connected to the processing tank 1 and the base 9 respectively. The lifting mechanism is inside the closed cover 101, and the bottom of the closed cover 101 is fixedly connected to a drain seat 112. One side of the closed cover 101 is connected to an L-shaped tube 113, and one end of the L-shaped tube 113 is connected to the collection bucket 7;

[0055] A water storage barrel 8 is disposed at one end of the base 9, a connecting pipe is disposed at the upper end of the water storage barrel 8, a water spray head 114 is disposed at one end of the connecting pipe, and the water spray head 114 penetrates the closed cover 101 and is fixedly connected thereto.

[0056] Preferably, when impurities discharged from the solid outlet 103 fall on the sealing plate 2 and need further cleaning, a water spray head 114 is provided, and the water spray head 114 passes through the sealing cover 101 to flush the sealing plate 2, thereby flushing the impurities into the sealing cover 101. The impurities in the sealing cover 101 finally flow into the collecting barrel 7 through the L-shaped tube 113, and the impurities are emptied. There is no need to manually clean the polluting impurities, thereby improving safety.

[0057] The lower end of the cover plate is fixedly connected with a plurality of connecting rods 206, the lower end of the connecting rods 206 is fixedly connected with a bottom ring 207, the upper end of the threaded sleeve 202 is fixedly connected with a lifting ring 208, the connecting rods 206 penetrate through the lifting ring 208 and slide with it, a spring member is arranged at the center of the lifting ring 208, and the two ends of the spring member are respectively connected with the cover plate and the threaded sleeve 202.

[0058] Preferably, when the fine mesh 111 performs the final filtration on the wastewater, as the wastewater is gradually discharged, the impurities filtered by the fine mesh 111 will also gradually increase, and the discharge speed of the wastewater will be reduced. When the wastewater is discharged to the end, too many impurities may even completely block the liquid port 104, causing the remaining wastewater to be unable to be discharged normally or at an extremely slow speed, greatly affecting the overall treatment efficiency. At this time, the rotation of the central rotating rod 106 can drive the scraper rod 102 to rotate, and the impurities on the fine mesh 111 can be scraped off in advance, thereby unblocking the blocked liquid port 104, so that the subsequent wastewater can be discharged in time, greatly improving the efficiency of wastewater discharge;

[0059] Preferably, a spring member is provided so that a reaction force is always generated between the cover plate and the threaded sleeve 202. When the cover plate contacts the lifting ring 208 (such as Figure 4 As shown in the figure, the reaction force of the spring part is the largest. When the central rotating rod 106 rotates, it drives the scraper rod 102 to rotate in advance, and at the same time drives the threaded rod 203 to rotate, thereby driving the threaded sleeve 202 to descend, and the threaded sleeve 202 drives the lifting ring 208 to descend (a guide sleeve 4 and a guide column 401 are provided to guide the movement of the sealing plate 2). Due to the existence of the above-mentioned reaction force, when the threaded sleeve 202 and the lifting ring 208 descend, the reaction force makes the spring part support the sealing plate 2 and still maintain the current height, that is, the sealing of the solid port 103 is guaranteed, until the lifting ring 208 contacts the bottom ring 207, thereby driving the sealing plate 2 to descend, and at this time, the residual waste water inside is also quickly emptied under the scraping action of the scraper rod 102, and then the impurities can be discharged from the solid port 103 under the action of the scraper rod 102. By delaying the opening of the sealing plate 2, the blockage is cleared to accelerate the emptying of the residual waste water, and the internal impurities are further scraped and emptied for internal cleaning, which is highly practical.

[0060] The stirring mechanism includes a motor 115 . The lower end of the motor 115 drives a stirring shaft 116 . The stirring shaft 116 penetrates the processing tank 1 and is rotatably connected thereto. The outer end of the stirring shaft 116 is provided with a plurality of stirring rods.

[0061] A vertical groove is provided at the lower end of the stirring shaft 116, and vertical openings 107 are provided on four sides of the vertical groove. A hollow rod 108 is fitted in the gap in the vertical groove, and guide columns 109 are fixedly connected to the four sides of the hollow rod 108. The guide columns 109 extend to the vertical opening 107 and slide with it. A locking mechanism is fixedly connected to the lower end of the hollow rod 108, and a buoyancy disk 110 is provided on the outside of the locking mechanism. The upper end of the center rotating rod 106 is similarly provided with a locking mechanism.

[0062] Preferably, the motor 115 drives the stirring shaft 116 and the stirring support rod to stir and mix the wastewater, and a buoyancy disc 110 and a hollow rod 108 are provided, so that during the wastewater treatment process, the buoyancy of the buoyancy disc 110 and the hollow rod 108 drives the engaging mechanism at the lower end of the hollow rod 108 to float up and separate from the engaging mechanism on the lower side, and the two do not interfere with each other. Then, the valve of the water outlet pipe 105 is opened to discharge the wastewater. When the liquid level drops to the buoyancy disc 110, the buoyancy disc 110 is The liquid level drops synchronously until the upper and lower engaging mechanisms are locked with each other. The motor 115 can transmit torque through the engaging mechanism to drive the central rotating rod 106 to rotate, thereby driving the scraper rod 102 to rotate in advance, scraping impurities on the fine screen 111 in advance, accelerating the emptying of residual wastewater, and opening the solid port 103 to empty impurities after emptying. This realizes that the motor 115 drives the stirring mechanism while automatically starting the scraper rod 102 to scrape when a certain amount of wastewater remains, and the degree of automation is high.

[0063] Preferably, the guide column 109 is inserted into the vertical opening 107 , so that the stirring shaft 116 can transmit torque to drive the hollow rod 108 to rotate without affecting the lifting and lowering of the hollow rod 108 .

[0064] The engaging mechanism includes a pair of supports 3, which are respectively fixed to the lower end of the hollow rod 108 and the upper end of the central rotating rod 106. A plurality of engaging columns 301 are fixedly connected to the upper part of the supports 3, and one end of the engaging column 301 is provided with a round chamfer.

[0065] Preferably, a plurality of engaging columns 301 are provided so that when the engaging mechanism is engaged, the engaging columns 301 on the upper and lower sides are staggered with each other, so as to transmit torque to drive the central rotating rod 106 to rotate, and the engaging columns 301 are provided with round chamfers to increase the fault tolerance of the engagement.
