Description

Technical Field

[0001] The utility model relates to the technical field of plastic recycling and processing, in particular to a sewage treatment device for washing recycled plastic particles. Background Art

[0002] Recycled plastic particles belong to the category of plastic particles. Recycled plastics are plastics produced by recycling used new materials or discarded plastics through a screw machine, and then cut into granular plastic particles by a pelletizer. Because the recycled materials contain dust, etc., the plastic particles need to be cleaned. The wastewater after cleaning contains a large amount of sludge, which needs to be treated before discharge.

[0003] For example, a Chinese patent publication number CN206156822U discloses a wastewater treatment device for washing recycled plastic particles. The floating particles in the wastewater are removed from the top of the pool by setting up a sedimentation tank. The sludge in the wastewater is deposited in the sludge chamber and then sent to the sludge filter press through the sludge conveying pipe and the sludge conveying pump. The filtrate obtained after filtration can be reused for washing the next batch of plastic particles, thereby saving water. The setting of pumping clean water into the pipeline prevents the sludge conveying pipeline from being blocked and improves the filtration efficiency of the sludge filter press.

[0004] However, the above patent has certain disadvantages. When the soil settles and stratification occurs between the sewage, the deposited mud layer cannot be treated, which over time will cause the mud layer to emit a foul odor in the sedimentation area. In addition, when treating sewage, only the sludge in the sewage can be treated, and lighter suspended matter cannot be treated. Utility Model Content

[0013] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0014] 1. The utility model provides a sewage treatment device for cleaning recycled plastic particles. Since the recycled materials contain dust and the like, the recycled plastic particles need to be cleaned. The sewage after cleaning contains a large amount of sludge. The sewage enters the sewage tank from the liquid inlet tank and is on the left side of the diverter plate. After the sewage enters, the diverter plate separates the sewage to allow it to accumulate and settle, allowing the sludge in the sewage to rise with the accumulation of the liquid level, thereby settling inside the sewage tank, allowing the sewage to begin to stratify, and as the water level continues to rise, the upper clean layer overflows the diverter plate and passes through the guide groove into the space where the water pump is located, and the water pump discharges the treated sewage for secondary utilization, while the sludge settled in the sewage tank is drained by pulling out the plug, and the motor is started to rotate the screw rod, and the moving block on its surface moves toward the position of the sewage trough along the surface of the guide rod, and the sludge settled at the bottom is scraped out of the sewage trough by the scraper at the bottom.

[0015] 2. The utility model provides a wastewater treatment device for cleaning recycled plastic particles. When the stratified wastewater overflows the diverter plate and enters the space where the water pump is located, the wastewater will fall through the filter screen, which will filter and adsorb the suspended matter in the wastewater, thereby preventing the debris floating on the surface of the wastewater from entering the water pump and being discharged. The impurities in the wastewater are reduced by the adsorption of the suspended matter by the filter screen, so that the wastewater can meet the standard for secondary use. Moreover, after each batch of wastewater cleaned with recycled plastic particles is treated, the cover plate can be pulled out to remove the plug rod from the wastewater tank, thereby removing the cover plate from the top of the wastewater tank. At this time, the filter screen can be disassembled from the filter frame by turning the screw for cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In this embodiment, the sewage treatment component 1 cooperates with the circulating filtration component 2, so that the recycled plastic particles can clean the sewage and then treat the soil and suspended matter. After treatment, the sewage is recycled again through the pump. The mud layer treated in the sewage treatment component 1 can also be cleaned, and the cleaning effect can be better and cleaner by scraping.

[0025] Example 2

[0026] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the inner wall of the sewage tank 11 and the left side of the diverter plate 12 are rotatably connected with a screw rod 16, the side of the sewage tank 11 is movably installed with a motor 14, the motor 14 is fixedly connected to one end of the screw rod 16, the inner wall of the sewage tank 11 and the left side of the diverter plate 12 are fixedly connected with a guide rod 15, the surface of the guide rod 15 and the surface of the screw rod 16 are movably connected with a moving block 17, the bottom of the moving block 17 is fixedly connected with a scraper 18, and the bottom of the scraper 18 is movably connected to the inner bottom surface of the sewage tank 11.

[0027] In the present embodiment, the recycled plastic particles need to be cleaned because the recycled materials contain dust and the like. The sewage after cleaning contains a large amount of sludge. The sewage enters the sewage tank 11 from the liquid inlet tank 22 and is located on the left side of the diverter plate 12. After the sewage enters, the diverter plate 12 separates the sewage to allow it to accumulate and settle, allowing the sludge in the sewage to rise with the accumulation of the liquid level, thereby settling inside the sewage tank 11, allowing the sewage to begin to stratify, and as the water level continues to rise, the upper clean layer overflows the diverter plate 12 and passes through the guide groove 13 into the space where the water pump 112 is located, and the water pump 112 discharges the treated sewage for secondary utilization, while the sludge settled in the sewage tank 11 is drained by pulling out the plug 110, and the motor 14 is started to rotate the screw 16, and the moving block 17 on its surface moves along the surface of the guide rod 15 toward the position of the sewage trough 19, and the sludge settled at the bottom is scraped out of the sewage trough 19 by the scraper 18 at the bottom.

[0028] Example 3

[0029] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a connecting rod 25 is fixedly connected to the bottom of the cover plate 21 and located directly above the water pump 112, and the other end of the connecting rod 25 is fixedly connected to a filter frame 26, the top of the filter frame 26 is threadedly connected with a screw 28, and a filter screen 27 is movably installed on the inner side of the filter frame 26, and the surface of the screw 28 is movably connected to the surface of the filter screen 27.

[0030] In this embodiment, when the stratified sewage overflows the diverter plate 12 and enters the space where the water pump 112 is located, the sewage will fall through the filter screen 27, and the filter screen 27 will filter and adsorb the suspended matter in the sewage, thereby preventing the debris floating on the surface of the sewage from entering the water pump 112 for discharge. After the suspended matter is adsorbed by the filter screen 27, the impurities in the sewage are reduced, so that the sewage can meet the standard for secondary use. Moreover, after each batch of recycled plastic particle cleaning sewage is processed, the cover plate 21 can be pulled out to allow the plug rod 23 to be removed from the sewage tank 11, so that the cover plate 21 can be removed from the top of the sewage tank 11. At this time, the filter screen 27 can be removed from the filter frame 26 by turning the screw 28 for cleaning.

[0031] The following is a detailed description of the working principle of the recycled plastic particle cleaning sewage treatment device.

[0032] like Figure 1-4As shown, the recycled plastic particles need to be cleaned because the recycled materials contain dust and the like. The sewage after cleaning contains a large amount of sludge. The sewage enters the sewage tank 11 from the liquid inlet tank 22 and is on the left side of the diverter plate 12. After the sewage enters, the diverter plate 12 separates the sewage to allow it to accumulate and settle, allowing the sludge in the sewage to rise with the accumulation of the liquid level, thereby settling inside the sewage tank 11, allowing the sewage to begin to stratify. As the water level continues to rise, the upper clean layer overflows the diverter plate 12 and passes through the guide groove 13 into the space where the water pump 112 is located, and the water pump 112 discharges the treated sewage for secondary utilization. When the stratified sewage overflows the diverter plate 12 and enters the space where the water pump 112 is located, the sewage falls through the filter screen 27, and the filter screen 27 filters and absorbs the suspended matter in the sewage. Attached, thereby preventing the debris floating on the sewage surface from following into the water pump 112 for discharge, and reducing the impurities in the sewage after the suspended matter is adsorbed by the filter screen 27, so that the sewage can meet the standard for secondary use, and the sludge settled in the sewage tank 11 is drained by unplugging the plug 110, and starting the motor 14 to rotate the screw 16, and the moving block 17 on its surface moves along the surface of the guide rod 15 toward the position of the sewage trough 19, and the sludge settled at the bottom is scraped out of the sewage trough 19 by the scraper 18 at the bottom, and after each batch of recycled plastic particle cleaning sewage is processed, the cover plate 21 can be pulled out to allow the plug 23 to be removed from the sewage tank 11, so that the cover plate 21 can be removed from the top of the sewage tank 11, and the filter screen 27 can be removed from the filter frame 26 by rotating the screw 28 for cleaning.

[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
