Sewage treatment is widely applied in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and is also increasingly entering the daily life of ordinary people. Sewage treatment is generally divided into production sewage treatment and domestic sewage treatment.

[0003] The filter grilles of traditional sewage treatment tanks are mostly of fixed structures. After long-term use, impurities are likely to block the grille gaps, reducing the filtration efficiency and making cleaning extremely inconvenient. It requires frequent manual disassembly and cleaning, increasing the maintenance cost and labor intensity. At the same time, the sludge cleaning efficiency of most sedimentation tanks is low, lacking effective sludge pumping and anti-blocking measures, seriously affecting the overall effect of sewage treatment and the continuous and stable operation of the system, and it is difficult to meet the increasingly strict sewage treatment and environmental protection requirements. Therefore, a sedimentation tank for sewage treatment with an easily unloaded grille is needed. Summary of the Invention

[0014] Preferably, the traction assembly includes a traction seat. The traction seat is connected to the adjacent sides of the two transmission rods through steel wires.

Ball seats are fixedly connected to the front end of the bottom side of the discharge port and the top end of the left side of the traction seat respectively. The two ball seats are connected through a ball shaft.

[0015] Working principle: Sewage enters along the opening at the top side of the separation chamber, passes through the filter grille belt, then enters the filtration chamber along the connection port at the bottom ends of the separation chamber and the filtration chamber, passes through the first filter screen, and then along the connection port in the middle of the filtration chamber and the sedimentation chamber for sedimentation work, and passes through the second filter screen to complete the purification process and is discharged from the outlet at the top end of the sedimentation chamber. During this period, when the sliding frame driven by the electric slide rail makes a sliding displacement, the following work will be carried out: The displaced sliding frame drives the cleaning brush installed thereon to displace together, so that the cleaning brush is displaced in the direction of the filter grille belt, so that the cleaning brush contacts the surface of the filter grille belt, and the convex structure on the top side of the cleaning brush contacts the concave-convex structure on the bottom side of the abutment seat, so that the cleaning brush is subjected to force along the concave-convex structure, displaced, and reset by the spring sheet, so that when brushing the surface of the filter grille belt, the debris at the gap of the filter grille belt is impacted, so that the debris is ejected from the gap, and then discharged into the waste discharge channel through the scraping of the scraper later; During the displacement of the sliding frame, the rack 1 at the bottom is driven to mesh with the gear 1, so that the gear 1 drives one of the wide turbines through two meshing bevel gears, and the wide turbine drives another wide turbine synchronously through the synchronous belt and the synchronous wheel, so that the two wide turbines mesh and drive the flat turbine, so that the transmission rod connected to the flat turbine is driven, and the guide roller connected to it is driven to rotate, so that the guide roller passes through the guide groove opened on the surface, and under the limit guidance of the guide head, it moves left and right along the closed guide groove; When the transmission rod at the top moves, it will drive the rack 2 on the top side to move, and then the gear 2 connected to the rotating roller that is meshed and driven to rotate, so that the rotating roller rotates, and the rotating roller drives the spiral spiral tube connected to it to rotate together, so that the flocculant enters the main tube connected to the spiral tube along the liquid inlet pipe, and can follow the nozzle installed on the outer wall of the spiral tube to spray in the sewage, so that the soluble impurities in the sewage are flocculated and precipitated, and the spiral spiral tube has the effect of accelerating mixing; The working process of rack one each time is a back and forth movement, so that the indirectly driven rotating roller also has a back and forth forward and reverse rotation as a working process, so that the gear ring one on the rear side of the rotating roller moves synchronously with this trend and meshes with gear ring two, so that when the ratchet teeth on the inner circumference of gear ring two apply force to the ratchet pawl when gear ring two rotates forward, the ratchet pawl will lie in the groove opened on the inner shaft, so that the force is decomposed, and when the ratchet teeth on the inner circumference of gear ring two apply force to the ratchet pawl when gear ring two rotates reversely, the ratchet pawl rotates to the side away from the groove and applies force to the inner shaft, so that the inner shaft drives the rear end transmission roller to rotate through the synchronous belt synchronous wheel and two mutually meshing bevel gears, so that the transmission roller drives the filter grille belt to move, so that the filter grille belt is cleaned and unloaded at the next position; Two reciprocating drive rods drive two piston heads on the right side to move in the negative pressure chamber inside the suction cylinder, assisting in creating negative pressure. After the negative pressure chamber connected to the sludge discharge pipe creates negative pressure, negative pressure is generated at the opening of the sludge suction pipe connected to the sludge discharge pipe, sucking the sludge accumulated along the slope at the bottom side of the sedimentation chamber into the sludge discharge pipe. When the piston head is pushed into the negative pressure chamber, the inside of the sludge discharge pipe is pressurized, causing the sludge to be discharged from the outlet of the sludge discharge pipe. After the negative pressure chamber connected to the liquid suction pipe creates negative pressure, the connection port at the top of the sedimentation chamber will suck the water filtered through the second filter screen into the liquid suction pipe. When the piston head is pushed into the negative pressure chamber, the water will flow through the diversion pipe and the impact pipe, impacting the sedimented sludge at the opening of the diversion pipe to prevent the sludge from forming lumps and recycling the water back into the sedimentation chamber to prevent incomplete purification; Two reciprocating drive rods will pull the traction seat through the steel wire rope on the left side, causing the traction seat to pull the ball shaft connected by the ball seat at the top during rotation, thereby causing the discharge port to continuously swing and rotate. When the waste material discharged into the waste discharge channel reaches the discharge port, the discharging speed can be accelerated, and the certain amplitude of vibration generated by the rotation of the discharge port assists the waste material in the waste discharge channel to slide.

[0016] The present invention provides a sedimentation tank for sewage treatment with an easily unloadable grille. It has the following beneficial effects: 1. The present invention can effectively intercept the debris in the sewage and achieve automatic cleaning. The sliding frame drives the cleaning brush to reciprocate. With the elastic action of the spring piece and the cooperation of the abutting seat, the debris in the gaps of the grille belt can be thoroughly cleaned and scraped into the waste discharge channel, greatly improving the filtration efficiency and the self-cleaning ability of the grille, eliminating the need for frequent manual disassembly and cleaning, and reducing the maintenance cost.

[0017] 2. The present invention uniformly sprays the flocculant in the sewage by driving the spiral nozzle, accelerating the precipitation of impurities. And the efficient work of pumping out the sedimented sludge can prevent the sludge suction pipe from being blocked, improving the sewage treatment effect and the continuous operation stability of the system, and enhancing the overall treatment efficiency.

[0018] 3. The present invention realizes the swinging vibration of the discharge port through the traction assembly, accelerating the discharging speed of the waste material, preventing the waste discharge channel from being blocked, and ensuring the smooth discharge of the sludge and the waste material.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment: An embodiment of the present invention provides a sedimentation tank for sewage treatment with an easily unloaded grille, including: Please refer to the attached Figure 1 - attached Figure 3 , a treatment tank 1, in which a separation chamber, a filtration chamber, and a sedimentation chamber are sequentially formed from left to right inside the treatment tank 1, and the separation chamber, the filtration chamber, and the sedimentation chamber are interconnected. An inclined filtration grille belt 2 is arranged inside the separation chamber. The filtration grille belt 2 is supported and driven by driving rollers 3 arranged inside the front and rear ends. A baffle 4 for blocking sundries is fixedly connected to the outer wall of the filtration grille belt 2, which is used to divide the filtration grille belt 2 into different treatment areas to facilitate the positioning and cleaning of subsequent waste cleaning and unloading work, and can prevent the waste from being displaced elsewhere due to the influence of water flow. Filter screens 5 are installed on the inner walls of the filtration chamber and the sedimentation chamber. Sewage enters through the opening on the top side of the separation chamber, passes through the filtration grille belt 2, then enters the filtration chamber through the communication port at the bottom end of the separation chamber and the filtration chamber, passes through the first filter screen 5, and then enters the sedimentation chamber through the communication port in the middle of the filtration chamber and the sedimentation chamber for sedimentation work, and passes through the second filter screen 5 to complete the purification process, and is discharged from the outlet at the top end of the sedimentation chamber. An electronic valve is connected to the outlet to open and discharge after the sedimentation reaction is complete.

[0023] Please refer to the attached Figure 4 - attached Figure 6 , a sliding frame 8, the rear end of the sliding frame 8 is displaced on the front side of the treatment tank 1 through an electric slide rail 6. The front end of the electric slide rail 6 is slidably connected to a sliding rod 7, and the left end of the sliding rod 7 is fixedly connected to the treatment tank 1. The sundries blocked on the surface of the filtration grille belt 2 are assisted in cleaning by a cleaning component under the bottom side of the sliding frame 8 to unload the sundries into the waste discharge channel 13 fixed on the left side of the treatment tank 1 for discharging. The cleaning component includes a contact seat 12 fixedly connected to the inner wall of the separation chamber and a plurality of cleaning brushes 9 slidably connected to the bottom side of the left end of the sliding frame 8. The top ends of the cleaning brushes 9 are connected to the top side of the sliding frame 8 through spring pieces 11. A scraping plate 10 is arranged on the right side of the cleaning brush 9, and the top side of the scraping plate 10 is fixedly connected to the sliding frame 8; Specifically, the sliding frame 8 that is displaced drives the cleaning brush 9 mounted thereon to be displaced together, thereby causing the cleaning brush 9 to be displaced in the direction of the filter grille belt 2, so that the cleaning brush 9 contacts the surface of the filter grille belt 2, and the convex structure on the top side of the cleaning brush 9 abuts against the concave-convex structure on the bottom side of the abutting seat 12. Thus, the cleaning brush 9 is stressed along the concave-convex structure and displaced, and is reset by the spring piece 11. The bristles of the cleaning brush 9 are made of elastic hard plastic, so as to impact the debris at the gaps of the filter grille belt 2 when brushing the surface of the filter grille belt 2, causing it to pop out from the gaps, and then being discharged into the waste discharge channel 13 by the scraping of the scraper 10 subsequently.

[0024] Please refer to the attached Figure 7 and the attached Figure 8 , the frame body 14, the frame body 14 is fixedly connected to the front bottom end of the treatment tank 1. When the sliding frame 8 is displaced, the transmission trigger assembly drives the two transmission rods 15 at the rear side of the frame body 14 to be displaced. The trigger assembly includes a wide turbine 16 and a flat turbine 17 that are meshed with each other and a guiding head 19 fixedly connected to the middle of the rear side of the frame body 14. The wide turbine 16 is rotatably connected to the left end of the frame body 14. The wide turbine 16 is fixedly connected to the outer wall left end of the transmission rod 15. A guiding roller 18 is fixedly connected to the middle of the outer wall of the transmission rod 15. A closed guiding groove is formed on the outer wall of the guiding roller 18. The guiding head 19 is slidably connected to the guiding groove. The right end of one of the wide turbines 16 is connected to a gear one 20 through two meshed bevel gears. A rack one 21 is fixedly connected to the bottom end of the sliding frame 8, and the rack one 21 is meshed with the gear one 20. The left sides of the two wide turbines 16 are connected by two synchronous wheels driven by a synchronous belt; Specifically, during the displacement of the sliding frame 8, the rack one 21 at the bottom end will be driven to mesh with the gear one 20, causing the gear one 20 to drive one of the wide turbines 16 through two meshed bevel gears. The wide turbine 16 synchronously drives the other wide turbine 16 through a synchronous belt and synchronous wheels, causing the two wide turbines 16 to mesh and drive the flat turbine 17, so that the transmission rod 15 connected to the flat turbine 17 is driven and drives the guiding roller 18 connected thereto to rotate. Thus, the guiding roller 18 is displaced left and right along the closed guiding groove under the limiting and guiding of the guiding head 19 through the guiding groove formed on the surface. Among them, the meshing grooves formed on the wide turbine 16 and the flat turbine 17 are surrounded curve structures to adapt to displacement movement while meshing. The initial positions of the two transmission rods 15 are opposite to the initial position of the guiding roller 18, causing the two transmission rods 15 to move in opposite directions when driven by the guiding roller 18.

The front side of the rotating roller 22 is connected to one of the transmission rods 15 through the meshing gear two 23 and rack two 24, so as to drive the medicine spraying pipe group to spray flocculant inside the sedimentation chamber for sewage sedimentation work, and indirectly rotate the rear transmission roller 3 through the transmission assembly. The gear two 23 is fixedly connected to the front side of the rotating roller 22. The rack two 24 is slidably connected to the front side of the treatment tank 1 and rotatably connected to the outer wall right end of one of the transmission rods 15 at the bottom end. The medicine spraying pipe group includes a spiral pipe 25 fixedly connected to the inner wall of the rotating roller 22 and a liquid inlet pipe 40 rotatably connected to the rear side of the treatment tank 1. The spiral pipe 25 is spiral and there are multiple of them, surrounding the inner wall of the rotating roller 22. A plurality of sludge suction pipes 26 are installed on the outer wall of the spiral pipe 25. The input end of the spiral pipe 25 penetrates the rear side of the rotating roller 22, and the input ends of the multiple spiral pipes 25 are fixedly connected to a main pipe 39. The rear end of the main pipe 39 is rotatably connected to the liquid inlet pipe 40. The liquid inlet pipe 40 is externally connected to a supply pipe providing a mixed flocculant liquid; Specifically, when the top transmission rod 15 moves, it will drive the top rack two 24 to move, thereby meshing and driving the gear two 23 connected to the rotating roller 22 to rotate, causing the rotating roller 22 to rotate. Thus, the rotating roller 22 drives the connected spiral spiral pipe 25 to rotate together. After the flocculant enters the main pipe 39 connected to the spiral pipe 25 along the liquid inlet pipe 40, it can be sprayed in the sewage following the nozzles installed on the outer wall of the spiral pipe 25, so that the soluble impurities in the sewage flocculate and precipitate. The spiral spiral pipe 25 has the effect of accelerating mixing.

[0026] Please refer to the appendix Figure 9 - appendix Figure 11 , the sludge suction pipes 26. The number of the sludge suction pipes 26 is multiple and they are located at the inner bottom end of the sedimentation chamber to suck out the sludge deposited at the inner bottom end of the sedimentation tank. The input ends of the multiple sludge suction pipes 26 penetrate the outer wall of the treatment tank 1 and are equipped with a sludge discharge pipe 29. The opening of the diversion pipe 28 is cleaned by water jet through the cleaning assembly to prevent the opening of the diversion pipe 28 from being blocked. The sludge discharge pipe 29 and the input end of the cleaning assembly both create negative pressure through the suction assembly. The suction assembly is driven by two transmission rods 15.

[0027] Please refer to the appendix Figure 11 - appendix Figure 13, the cleaning component includes an impact pipe 27 and a liquid suction pipe 30 fixedly connected to the outer periphery of the input end of the sludge suction pipe 26. The output end of the impact pipe 27 is connected to the inside of the sludge suction pipe 26 and is equipped with a one-way valve diaphragm. The liquid suction pipe 30 is connected to the impact pipe 27 through a diversion pipe 28. The input end of the liquid suction pipe 30 is fixedly connected to the right top end of the treatment tank 1 and is connected to the sedimentation chamber. The suction component includes a suction cylinder 31. The rear side of the suction cylinder 31 is fixedly connected to the front sides of the sludge discharge pipe 29 and the liquid suction pipe 30. Two negative pressure chambers are provided inside the suction cylinder 31, and the two negative pressure chambers are not related to each other. A piston head 32 is slidably connected inside the negative pressure chamber. The left side of the piston head 32 is fixedly connected to the right side of the transmission rod 15; Specifically, the two reciprocating transmission rods 15 drive the two piston heads 32 on the right side to move in the negative pressure chambers inside the suction cylinder 31 to assist in creating negative pressure. After the negative pressure is created in the negative pressure chamber connected to the sludge discharge pipe 29, a negative pressure is generated at the opening of the sludge suction pipe 26 connected to the sludge discharge pipe 29, sucking the sludge accumulated along the slope at the bottom side of the sedimentation chamber into the sludge discharge pipe 29. When the piston head 32 is pushed into the negative pressure chamber, the inside of the sludge discharge pipe 29 is pressurized, causing the sludge to be discharged from the output port of the sludge discharge pipe 29. Among them, a one-way valve is connected between the sludge discharge pipe 29 and the sludge suction pipe 26 to prevent backflow during sludge discharge. After the negative pressure is created in the negative pressure chamber connected to the liquid suction pipe 30, the connection port with the top of the sedimentation chamber will suck the water filtered through the second filter screen 5 into the liquid suction pipe 30. When the piston head 32 is pushed into the negative pressure chamber, the water will flow along the diversion pipe 28 and the impact pipe 27, impacting the sediment sludge at the opening of the diversion pipe 28 to prevent the sludge from forming lumps and recycling the water back into the sedimentation chamber to prevent incomplete purification. Among them, the liquid suction pipe 30 is equipped with a one-way valve to prevent backflow during the water impact operation.

[0028] Please refer to the appendix Figure 2 、appendix Figure 16 and appendix Figure 17 , the transmission component includes a first toothed ring 41 fixedly connected to the rear side of the rotating roller 22. The left side of the first toothed ring 41 is meshed with a second toothed ring 42. One side of the second toothed ring 42 is rotatably connected to the treatment tank 1. The middle end of the other side of the second toothed ring 42 is rotatably connected to an inner shaft 43. The outer periphery of the inner shaft 43 is connected with a pawl 44 through a torsion spring. The inner periphery of the second toothed ring 42 is provided with ratchet teeth that abut against the pawl 44. The inner shaft 43 is connected to the rear transmission roller 3 through two synchronous wheels driven by a synchronous belt and two meshing bevel gears; Specifically, the working process of the first rack 21 is to move back and forth for one round trip. As a result, the rotating roller 22 that is indirectly driven also takes one round trip of forward and reverse rotation as one working process, causing the first tooth ring 41 behind the rotating roller 22 to move synchronously in the same trend and engage with the second tooth ring 42. When the ratchet teeth on the inner circumference of the second tooth ring 42 apply force to the pawl 44 during the forward rotation of the second tooth ring 42, the pawl 44 will lie in the groove formed on the inner shaft 43, thereby decomposing the force. When the ratchet teeth on the inner circumference of the second tooth ring 42 apply force to the pawl 44 during the reverse rotation of the second tooth ring 42, the pawl 44 rotates towards the side away from the groove and applies force to the inner shaft 43. As a result, the inner shaft 43 drives the rear transmission roller 3 to rotate through the synchronous belt and two meshing bevel gears, causing the transmission roller 3 to drive the filter grille belt 2 to displace, and enabling the cleaning and discharging work at the next position of the filter grille belt 2.

[0029] Please refer to the attached Figure 5 , the attached Figure 14 and the attached Figure 15 , the discharge port 33, the rear side of the discharge port 33 is connected to the front end of the waste discharge channel 13 through a rubber sleeve 37, the bottom rear end of the discharge port 33 is rotatably connected to the bottom front side of the front end of the waste discharge channel 13, and the discharge port 33 swings through a traction assembly driven by two transmission rods 15 to vibrate the waste at the opening of the discharge port 33 to prevent blockage. The traction assembly includes a traction seat 34, the traction seat 34 is connected to the adjacent sides of the two transmission rods 15 through steel wires 38, the rear side of the traction seat 34 is rotatably connected to the treatment tank 1, and the bottom front end of the discharge port 33 and the left top end of the traction seat 34 are both fixedly connected with ball seats 35, and the two ball seats 35 are connected through a ball shaft 36; Specifically, the two reciprocating transmission rods 15 will pull the traction seat 34 through the steel wire 38 on the left side, causing the traction seat 34 to pull the ball shaft 36 connected by the ball seat 35 at the top end during rotation, thereby causing the discharge port 33 to continuously swing and rotate. When the waste discharged into the waste discharge channel 13 reaches the discharge port 33, the blanking speed can be increased, and the certain amplitude of vibration generated by the rotation of the discharge port 33 assists the waste in the waste discharge channel 13 to slide.
