Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a papermaking wastewater treatment device. Background Technology

[0002] The pollutants contained in papermaking wastewater are mainly short fibers, microfibers, sludge, and organic pollutants. Direct discharge of papermaking wastewater not only causes environmental pollution but also wastes fiber resources. Some manufacturers now use flocculants to add to the wastewater after sand and sludge removal to flocculate and precipitate the fibers in the wastewater for recycling. This can achieve a certain degree of fiber resource recovery and cost savings.

[0003] Currently, existing papermaking wastewater treatment devices primarily treat wastewater by filtering out fibers and other impurities through filters. However, due to the high water absorption of paper fibers, the filtered fibers still contain a significant amount of wastewater. Existing treatment devices often treat the wastewater by draining it, which is not only inefficient but also produces only mediocre wastewater treatment results. Furthermore, the fiber impurities in papermaking wastewater easily clog the filters, requiring frequent cleaning and further impacting wastewater treatment efficiency. Therefore, we propose a papermaking wastewater treatment device. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1 to 6This utility model provides a technical solution: a papermaking wastewater treatment device, including a treatment box 1, a concave plate 2 fixedly installed on one side of the top of the treatment box 1, conveying rollers 3 are provided on the inner sides of both the treatment box 1 and the concave plate 2, a conveying filter belt 4 is sleeved on the outer side of the two conveying rollers 3, a motor 5 is provided on one side of the treatment box 1, the output end of the motor 5 is fixedly connected to one end of the conveying roller 3, a support roller 6 is rotatably installed on the inner side of the concave plate 2, a sliding groove 7 is provided on the inner side of both sides of the concave plate 2, two limiting guide rods 8 are fixedly installed inside the sliding groove 7, a slider 9 is slidably installed on the outer side of the two limiting guide rods 8, a rotating shaft 10 is rotatably installed on the inner side of the two sliders 9, a pressure roller 11 is fixedly installed on the outer side of the rotating shaft 10, the pressure roller 11 cooperates with the support roller 6, the pressure roller 11 and the support roller 6 cooperate with the conveying filter belt 4, a positioning post 12 is fixedly installed on the top of the inner side of the sliding groove 7 and the top of the slider 9, and a pressure spring 13 is installed on the outer side of the two positioning posts 12. The spring force of the pressure spring 13 can provide downward pressure to the slider 9, thereby causing the pressure roller 11 to adhere tightly to the surface of the conveyor filter belt 4. When the filtered fibers are conveyed, the pressure roller 11 squeezes the fibers, thereby quickly discharging the wastewater from the fibers.

[0025] A high-pressure air pump 17 is fixedly installed on one side of the concave plate 2, and an air distribution plate 18 is fixedly installed on the inner side of the concave plate 2. The output end of the high-pressure air pump 17 is fixedly connected to the input end of the air distribution plate 18. Several air outlets 19 are opened at the bottom of the air distribution plate 18, and the air outlets 19 cooperate with the conveyor filter belt 4. By setting the air distribution plate 18 on the inner side of the conveyor filter belt 4, high-pressure gas can be blown out from the inner side of the conveyor filter belt 4, thereby achieving the effect of backwashing and effectively blowing down the filtered fibers.

[0026] Two sleeves 20 are fixedly installed on the top of the vertical plate 14. A slide rod 21 is slidably installed inside the top of the sleeve 20. A scraper 24 is fixedly installed at one end of the slide rod 21 and cooperates with the conveying filter belt 4. A slide plate 22 is fixedly installed at the other end of the slide rod 21. A support spring 23 is installed inside the sleeve 20, and the slide plate 22 cooperates with the support spring 23. Through the arrangement of the sleeve 20, slide rod 21, slide plate 22, support spring 23 and scraper 24, the elastic force of the support spring 23 can push the slide plate 22, thereby making the scraper 24 stick tightly to the outside of the conveying filter belt 4, and scraping off some firmly attached fibrous impurities.

[0027] A vertical plate 14 is fixedly installed in the middle of the inner side of the concave plate 2. A slag discharge port 15 is opened inside one side of the concave plate 2. A slag discharge plate 16 is fixedly installed on the top of one side of the vertical plate 14, and the slag discharge plate 16 penetrates the interior of the slag discharge port 15. The vertical plate 14 prevents impurity fibers from falling back into the processing box 1. The slag discharge plate 16 can cooperate with the air distribution plate 18 to allow the blown-down impurities to be discharged through the slag discharge plate 16 and the slag discharge port 15.

[0028] A guide plate 25 is fixedly installed on one side of the top of the treatment tank 1. The guide plate 25 cooperates with the conveyor filter belt 4. By setting the guide plate 25, the wastewater to be treated can be guided to flow onto the surface of the conveyor filter belt 4 for filtration.

[0029] A triangular ramp 26 is fixedly installed at the bottom inside the treatment tank 1. The triangular ramp 26 ensures the discharge of wastewater.

[0030] A drain pipe is installed at the bottom of one side of the treatment tank 1, and a valve is installed inside the drain pipe. The drain pipe and valve are used to discharge wastewater.

[0031] In summary, during operation, the wastewater to be treated in this papermaking wastewater treatment device is transported to the guide plate 25 via an external water pipe. The guide plate 25 guides the wastewater to the conveyor filter belt 4. Simultaneously, the motor 5 is activated to drive the conveyor roller 3 and the conveyor filter belt 4 to rotate. After the wastewater flows onto the conveyor filter belt 4, the fibers in the wastewater are filtered out. The filtered fiber impurities are transported to the area below the pressure roller 11 as the conveyor filter belt 4 rotates. The pressure roller 11 and the idler roller 6 then squeeze the fiber impurities, thereby ensuring rapid discharge of wastewater and improving wastewater treatment efficiency. The squeezed fiber impurities are then conveyed to the filter belt 4. After the mesh belt 4 rotates above the slag discharge plate 16, some fibrous impurities fall onto the slag discharge plate 16 due to their own gravity. At the same time, by turning on the high-pressure air pump 17, high-pressure air can be blown into the air distribution plate 18. The air is blown towards the conveying filter mesh belt 4 through the air outlet 19, which can blow the residual fibers on the conveying filter mesh belt 4 down onto the slag discharge plate 16. At the same time, the impurities on the slag discharge plate 16 are blown out through the slag discharge port 15, thus realizing the discharge of impurities. Finally, some firmly attached fibrous impurities can be scraped off by the scraper 24 after the conveying filter mesh belt 4 rotates above it, thereby further improving the discharge of impurities and the cleaning of the conveying filter mesh belt 4.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
