Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly relates to a sludge discharging device for a hydrolysis acidification tank after carpet weaving, dyeing and finishing processing. Background Art

[0002] Carpet weaving and dyeing is one of the processes in carpet production. According to the physical and chemical properties of carpet yarns, appropriate dyes are selected to make the dyes firmly adhere to the wool fibers evenly and thoroughly. During the carpet weaving and dyeing process, chemical water washing is required, and a large amount of wastewater will be generated during the process. This part of the wastewater needs to be assisted in purification through a hydrolysis acidification tank. The hydrolysis acidification tank utilizes the microbial metabolic activities under anaerobic conditions to convert the soluble organic substances in the wastewater into organic acids and volatile fatty acids, thereby realizing the preliminary treatment and degradation of the wastewater. A large amount of sludge will be generated during the purification process. The traditional sludge discharging method is to suck it through a sludge discharging pump. Since the hydrolysis acidification tank mainly uses microorganisms for auxiliary purification, during the suction process, a large amount of purified water and some microorganisms in the purification tank will be lost. After suction, the sludge still needs to be extruded by a machine, and adding an extrusion machine has a high cost. Summary of the Invention

[0044] Specific usage and function of this embodiment: When cleaning the sludge in the hydrolysis acidification tank 101, it is necessary to control the rotation of the screw rod 401 on one side of the support rod A 404 and the lifting plate 403. To rotate this screw rod 401, the motor in the corresponding motor box 202 needs to be started. The motor controls the rotation of the main rotating rod 201. The main rotating rod 201 drives the driving rod 204 to rotate through the bevel gear assembly A 203. The driving rod 204 rotates and drives this screw rod 401 to rotate through the bevel gear assembly B 205 on its surface. Since the surface of the screw rod 401 is provided with threads, it can control the downward sliding of the lifting plate 403, the support rod A 404, and the sliding plate 405 during the rotation process. When the screw rod 401 rotates, the gear at the bottom of the screw rod 401 drives the rotating rod 501 to rotate through the gear belt 502. During the rotation of the rotating rod 501, the cleaning rod 504 at the top will drive the inside of the bearing connecting cylinder 301 to rotate, cleaning the sludge inside the bearing connecting cylinder 301. The sliding plate 405 slides downward, and the sludge enters the inside of the sludge discharge pipe 302. When the sliding plate 405 slides into the inside of the sludge discharge pipe 302, the sludge discharge control mechanism 2 on one side of the support rod B 406 is started. The support rod B 406 drives the entire filter water component 407 to slide downward. The filter plate 4072 will first contact the sludge in the sludge discharge pipe 302. The filter plate 4072 continues to press down, and the water in the sludge enters the inside of the fixed ring 4071 from the filter plate 4072. The filter plate 4072 continues to apply pressure, and the water in the sludge will generate a thrust on the plug rod 4077. The top plate 4076 at the top of the plug rod 4077 moves upward under the thrust, the pull rod 4075 slides, and the spring A 4074 contracts. The water in the sludge is squeezed out. After a certain degree of extrusion movement, the two screw rods 401 rotate simultaneously, and the filter water component 407 and the sliding plate 405 slide downward simultaneously. The filter water component 407, the sliding plate 405, and the compressed sludge in the middle slide out from the inside of the sludge discharge pipe 302. Then, the electric telescopic rod 601 is started. The electric telescopic rod 601 controls the sliding of multiple cutting knives 606 through the control frame 602. Since one end of the cutting knife 606 slides into the discharge push frame 603 and contacts the spring B 605, the cutting knife 606 is retractable, and the length of the cutting knife 606 is longer than that of the discharge push frame 603. The cutting knife 606 first contacts the extruded sludge and cuts the sludge. The push frame 603 slides and contacts the cut sludge, separating the sludge from the extrusion sludge discharge device 4, and completing the sludge discharge.
