[0005] The specification of prior art 1 discloses a wastewater recycling system and circulation system applied to a PC precast component factory. In use, the wastewater recycling system can prevent wastewater from settling and hardening at the bottom of the tank, thereby separating sludge and clean water and realizing the recycling of wastewater. However, in actual applications, the sediment in the sedimentation tank used for wastewater recycling is not easy to clean, which affects the efficiency of the sedimentation tank in treating wastewater. Summary of the Invention

[0006] This invention provides a wastewater self-circulation system for the production of precast components, aiming to solve the problem that it is inconvenient to clean the bottom sediment after the wastewater tank in the existing wastewater recycling system is emptied.

[0019] This utility model mainly includes a mixing plant, a sedimentation tank, and a water storage tank. In actual use, the mixing plant produces concrete, which generates a large amount of wastewater containing impurities that does not meet discharge standards. Therefore, the wastewater needs to be first introduced into the sedimentation tank for sedimentation and filtration, and then stored in the water storage tank. The water in the storage tank is used to irrigate the greenery in the plant area. After the water in the sedimentation tank is drained, the silt and impurities in the sedimentation tank need to be cleaned. During this process, the workers open the cover and simultaneously control the drive component, which drives the sludge scraper to move on the sedimentation tank, thereby scraping and gathering the silt and impurities at the bottom of the sedimentation tank and pushing them into the discharge port, where they fall into the screw feeder. The screw feeder then feeds the silt and impurities, which are finally discharged from the sewage outlet of the sedimentation tank. The mixing plant, sedimentation tank, and water storage tank achieve a self-circulation of wastewater treatment. The advantage of this setup is that it effectively cleans the silt and debris at the bottom of the sedimentation tank, facilitating rapid sedimentation for the next batch of wastewater and improving the efficiency of wastewater treatment.

[0027] The sewage discharge device includes a sludge scraping assembly, a drive assembly, and a screw feeder 102. The sludge scraping assembly is used to scrape away the dirt in the sedimentation tank 101. The drive assembly is used to drive the sludge scraping assembly to move above the sedimentation tank 101 to gather the dirt. The sedimentation tank 101 is provided with a discharge port 103 and a cover plate 104. The cover plate 104 is slidably sealed to the sedimentation tank 101. The screw feeder 102 is located below the discharge port 103 and is connected to the discharge port 103. The sedimentation tank 101 is provided with a sewage discharge port 105, and the outlet of the screw feeder 102 coincides with the sewage discharge port 105.

[0028] This utility model mainly includes a mixing plant, a sedimentation tank 101, and a water storage tank. In actual use, the mixing plant produces concrete, generating a large amount of wastewater containing impurities that does not meet discharge standards. Therefore, the wastewater needs to be first introduced into the sedimentation tank 101 for sedimentation and filtration, and finally stored in the water storage tank. The water in the storage tank is used to irrigate the greenery in the factory area. After the water in the sedimentation tank 101 is drained, the silt and impurities in the sedimentation tank 101 need to be cleaned. During this process, the operator opens the cover plate 104 and simultaneously controls the drive assembly, causing the drive assembly to... The drive scraper assembly moves on the sedimentation tank 101, scraping and gathering the sludge and impurities at the bottom of the sedimentation tank 101, and pushing the sludge and impurities into the discharge port 103, where they fall into the screw feeder 102. The screw feeder 102 feeds the sludge and impurities, which are finally discharged at the sewage outlet 105 of the sedimentation tank 101. The self-circulation of sewage treatment is achieved through the mixing tower, sedimentation tank 101, and water storage tank. The advantage of this setup is that it effectively cleans the sludge and debris at the bottom of the sedimentation tank 101, facilitating rapid sedimentation of the next batch of sewage and improving the efficiency of sewage treatment.

[0029] In some embodiments, a plurality of baffles 106 are provided on the sedimentation tank 101, the baffles 106 divide the sedimentation tank 101 into a plurality of sedimentation tanks 107, and adjacent sedimentation tanks 107 are interconnected.

[0030] In actual use, the purpose of setting up several baffles 106 is to divide the sedimentation tank 101 into several sedimentation tanks 107 to facilitate the graded sedimentation of sewage.

[0031] In some embodiments, the sludge scraping assembly includes a scraper 108, a connecting rod 109, and a sliding beam 110. Each sedimentation tank 107 is provided with a scraper 108 inside. The two ends of the scraper 108 are slidably connected to the inner wall of the sedimentation tank 107. The connecting rod 109 is disposed on the top of the scraper 108. The sliding beam 110 is slidably connected to the sedimentation tank 101 and fixedly connected to the connecting rod 109. The driving assembly is used to drive the sliding beam 110 to slide on the sedimentation tank 101.

[0032] In actual use, when it is necessary to scrape off the sludge and impurities at the bottom of the sedimentation tank 101, the drive component is controlled to operate. The drive component drives the sliding beam 110 to move above the sedimentation tank 101. When the sliding beam 110 moves, it in turn drives the connecting rod 109 and the scraper 108 to move. The scraper 108 is slidably connected to the bottom surface of the sedimentation tank 101. The scraper 108 scrapes off and gathers the sludge and impurities at the bottom of the sedimentation tank 101.

[0033] In some embodiments, the drive assembly includes a motor 111 and a lead screw drive mechanism, wherein the motor 111 is used to control the sliding beam 110 to slide on the sedimentation tank 101 via the lead screw drive mechanism.

[0034] In actual use, the screw drive mechanism includes a ball screw 117 and a screw nut 118. The screw nut 118 is fixedly installed on the sliding beam 110. One end of the ball screw 117 is fixedly connected to the output shaft of the motor 111, and the other end is engaged with the screw nut 118. When it is necessary to control the movement of the sliding beam 110, the operator needs to control the motor 111 to rotate. After the motor 111 rotates, it drives the ball screw 117 to rotate. After the ball screw 117 rotates, it drives the screw nut 118 and the sliding beam 110 to move as a whole on the sedimentation tank 101. This, in turn, drives the scraper 108 to move at the bottom of the sedimentation tank 101, scraping and gathering the sludge and impurities at the bottom of the sedimentation tank 101, and then discharging them through the discharge port 103 into the screw feeder 102.

[0035] In some embodiments, the sliding beam 110 is slidably engaged with the sedimentation tank 101 via a sliding component.

[0036] In actual use, the purpose of setting up the sliding component is to facilitate the sliding of the sliding beam 110, so that the sliding beam 110 has less friction and slides more smoothly.

[0037] In some embodiments, the sliding component includes a sliding protrusion 112 and a sliding recess 113. The sliding protrusion 112 is disposed on the sedimentation tank 101, and the sliding recess 113 is disposed on the sliding beam 110. The sliding recess 113 is used to slide on the sliding protrusion 112.

[0038] In actual use, the purpose of setting the sliding protrusion 112 and the sliding recess 113 is to facilitate the limiting of the sliding of the sliding beam 110, so that the sliding beam 110 is more stable when sliding.

[0039] In some embodiments, a discharge hopper 114 is provided below the discharge port 103. The bottom of the discharge hopper 114 converges towards the center to form a funnel-shaped structure. A discharge port 115 is provided at the center of the bottom of the discharge hopper 114. The discharge port 115 is connected to the screw feeder 102 through a pipeline, thereby enabling communication between the discharge hopper 114 and the screw feeder 102. The cover plate 104 is used to close the discharge port 103.

[0040] In actual use, when the sludge and impurities are gathered and pushed to the discharge port 103, the sludge and impurities fall from the discharge port 103 into the discharge bin 114. Since the side walls of the discharge bin 114 are all inclined and gather towards the center, the sludge and impurities will enter the screw feeder 102 through the discharge port 115. The screw feeder 102 runs continuously to discharge the sludge and impurities.

[0041] In some embodiments, a guide assembly is also provided above the sedimentation tank 101, which is used to guide the sliding of the sliding beam 110.

[0042] In actual use, the guide assembly includes a guide rod 119 and a support part 120. The support part 120 is set on the sedimentation tank 101, and the sliding beam 110 is provided with a guide hole. The sliding beam 110 is used to slide on the guide hole.

[0043] In some embodiments, the scraper 108 is provided with a V-groove.

[0044] In actual use, the purpose of setting the V-shaped groove is to facilitate the scraper 108 to better gather the sludge and impurities at the bottom of the sedimentation tank 101.
