Description

Technical Field

[0001] This utility model relates to the technical field of desliming equipment cleaning systems, specifically to desliming cleaning systems. Background Technology

[0002] Wastewater generated daily is transported to wastewater treatment plants for purification. During the purification process, wastewater undergoes multiple treatment steps, one of which is sludge removal. This sludge removal stage includes mechanical sludge removal and sedimentation tank sludge removal, with sedimentation tank sludge removal following mechanical sludge removal. Mechanical sludge removal utilizes sludge removal equipment, with centrifugal sludge dewatering machines and plate sludge dewatering machines being common examples. After a period of use, the sludge dewatering machine needs to be cleaned to prevent sludge from accumulating inside, causing blockages, and thus affecting its normal operation.

[0003] Publication (Announcement) No.: CN218076579U discloses a high-efficiency cleaning system for sludge dewatering filter cloth, including a support frame. A screw slide drive frame is fixedly mounted at the top of the support frame. A movable seat capable of horizontal movement is mounted on the screw slide drive frame. An electric telescopic rod is fixedly mounted at the bottom of the movable seat. A filter cloth cleaning frame is fixedly mounted at the bottom of the electric telescopic rod. A filter plate groove is formed at the bottom inner side of the filter cloth cleaning frame. By arranging staggered cleaning rollers and nozzle mounting strips on the inner side of the filter cloth cleaning frame, water can be sprayed from the nozzles on the nozzle mounting strips, coordinating with the rotation of the cleaning rollers, to wash the filter cloth on the filter plate surface, achieving a better cleaning effect.

[0004] The aforementioned known technology uses a nozzle to spray water to rinse the filter cloth during use, but it does not have a storage mechanism to store the mixture of water and sludge after rinsing, and it cannot recycle the mixed liquid, which not only increases the waste of water resources, but also increases processing costs.

[0005] Based on this, the present invention designs a sludge removal and cleaning system to solve the above problems. Utility Model Content

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] The present invention will be further described below with reference to the embodiments.

[0037] Example 1: Please refer to the appendix of the instruction manual. Figures 1-3The sludge removal and cleaning system includes a horizontal screw centrifuge 1, a sedimentation tank 2 located on one side of the horizontal screw centrifuge 1, and a cleaning mechanism located on the horizontal screw centrifuge 1. The horizontal screw centrifuge 1 includes a rotating drum and a screw pusher located inside the rotating drum, which is existing technology and will not be described in detail here. The cleaning mechanism includes a flushing pipe 3 sealed on the outer wall of the screw pusher and a water supply pipe 4 sealed to the flushing pipe 3. The outer wall of the sedimentation tank 2 is equipped with a water pump 5 with its input end sealed to it and a water pump 11 with its output end sealed to it. The output end of the water pump 5 and the end of the water supply pipe 4 away from the flushing pipe 3 are sealed to each other. In use, the water inside the sedimentation tank 2 is drawn out by the water pump 5, discharged into the interior of the flushing pipe 3 through the water supply pipe 4, and finally discharged through the flushing pipe 3 to flush the screw pusher.

[0038] The bottom of the decanter centrifuge 1 is equipped with a filter box 7 and a water supply pipe 6 connecting the filter box 7 and the decanter centrifuge 1. The water supply pipe 6, the filter box 7, and the interior of the decanter centrifuge 1 are interconnected, and the water supply pipe 6 is sealed to both the decanter centrifuge 1 and the filter box 7. A control valve, which can be a solenoid valve, is installed on the water supply pipe 6. The bottom of the drum is a conical surface that gradually decreases from the outside to the inside, which facilitates the entry of the rinsed mixture into the interior of the water supply pipe 6. Specifically, during the cleaning process, the inlet and outlet of the decanter centrifuge 1 are closed beforehand, and the solenoid valve is opened. The mixture enters the filter box 7 through the interior of the water supply pipe 6 for storage, reducing water loss and minimizing resource waste.

[0039] The filter box 7 is equipped with a filter belt 8 located inside it. The outer wall of the filter belt 8 has filter holes that are evenly distributed. The filter belt 8 blocks the sludge in the mixture, thereby filtering the mixture. The mesh size of the filter holes can be changed according to specific needs. Connecting slots 9 are opened on the left and right sides of the filter box (7), and the filter belt 8 passes through the interior of the connecting slots 9. The sludge attached to the top of the filter belt 8 is cleaned through the connecting slots 9, reducing the risk of clogging of the filter belt 8 and ensuring its working efficiency. The filter belt 8 is sealed to the outside of the filter box 7. The water supply pipe 3 10, which is sealed to the input end of water pump 2 11, enters the filter box 7. The mixed liquid falls to the top of the filter belt 8, where the sludge is blocked. The clean water flows through the filter hole 1 and falls to the bottom of the filter box 7. By starting water pump 2 11, the clean water enters the water supply pipe 3 10 and is finally discharged into the sedimentation tank 2 through the output end of water pump 2 11 for further treatment. This product can recycle the water, further reducing water waste and saving costs.

[0040] The filter belt 8 is equipped with a sewage discharge mechanism to remove sludge.

[0041] Example 2: Based on Example 1, please refer to the appendix of the instruction manual. Figure 1 , Figure 2 , Figure 4 and Figure 5 The sewage discharge mechanism includes sludge storage structures located on the left and right sides of the filter box 7, which can store sludge for subsequent treatment; and drive rollers 12 rotatably connected inside the two sludge storage structures and connected by filter belts 8. Each drive roller 12 is equipped with a motor that rotates it. The outer wall of the drive rollers 12 extends to the outside of the sludge storage structures. Rotating the two drive rollers 12 rotates the filter belt 8, which discharges the sludge located on its outer wall into the sludge storage structures through the connecting grooves 9. This eliminates the need for manual operation, making it convenient and labor-saving. The two drive rollers 12 are fixed inside the connecting grooves 9 and... The fixed partition 15 located inside the filter belt 8 cavity and the scraper 21 respectively set inside the two sludge storage structures and in frictional contact with the bottom of the filter belt 8, the scraper 21 can scrape off the sludge attached to the outer wall of the filter belt 8, improve the sludge discharge effect, improve the cleanliness of the outer wall of the filter belt 8, reduce the risk of clogging, and improve the filtration efficiency. In specific use, by turning on the motor, the drive roller 12 is rotated, the filter belt 8 starts to rotate, and the sludge is discharged into the sludge storage structure through the connecting groove 9 for storage. At the same time, the rotating filter belt 8 and the top of the scraper 21 are in frictional contact, and the scraper 21 scrapes off the sludge attached to the outer wall of the filter belt 8.

[0042] The drive roller 12 is provided with a conveying cavity 18 inside it; a tapered discharge hole 19 is provided inside the conveying cavity 18, and the interior of the discharge hole 19 is tapered from the inside to the outside; and a conveying pipe 20 is rotatably connected to the front end of the drive roller 12. The conveying pipe 20 is located at the center of the front end of the drive roller 12. The interior of the conveying pipe 20 and the interior of the conveying cavity 18 are interconnected. An air compressor is provided on one side of the horizontal screw centrifuge 1 and is sealed to the end of the conveying pipe 20 away from the horizontal screw centrifuge 1. The air compressor delivers high-pressure gas to the conveying pipe 20. In actual use, by inputting high-pressure gas into the interior of the conveying pipe 20, the air is discharged through the interior of the conveying cavity 18 and the discharge hole 19, and then discharged into the sludge storage structure through the filter hole. The gas will treat the sludge attached to the filter hole and treat the surface of the filter belt 8, reducing the risk of filter belt 8 clogging and improving its working efficiency.

[0043] The outer walls of the two drive rollers 12 are provided with drive tooth grooves 13, and the inner wall of the filter belt 8 is provided with drive tooth plates 14 that mesh with the two sets of drive tooth grooves 13. During the rotation of the filter belt 8, the meshing connection between the drive tooth grooves 13 and the drive tooth plates 14 can avoid the risk of the filter belt 8 shifting and improve the stability of the filter belt 8 during operation.

[0044] Both sets of sludge storage structures include a sludge storage tank 16 fixed to the outer wall of the filter box 7 and corresponding to the connecting channel 9; and a drain pipe 17 respectively sealed and connected to the bottom of the two sludge storage tanks 16.

[0045] Example 3: Based on Example 1, please refer to the appendix of the instruction manual. Figures 6-8 The difference between this embodiment and embodiment two is that the conveying pipe 20 and the water supply pipe 4 are connected, and water is conveyed into the inside of the conveying pipe 20, while the sludge storage structure is replaced.

[0046] Specifically, the sewage discharge mechanism includes sewage storage structures respectively arranged on the left and right sides of the filter box 7; drive rollers 12 respectively rotatably connected inside the two sewage storage structures and connected through the filter belt 8; fixed partitions 15 respectively fixed inside the two connecting slots 9 and located in the cavity of the filter belt 8; and scrapers 21 respectively arranged inside the two sewage storage structures and in frictional contact with the bottom of the filter belt 8.

[0047] The drive roller 12 is provided with a conveying cavity 18 inside it; a discharge hole 19, which is conical and opened inside the conveying cavity 18, is provided with a cone shape that gradually decreases in size from the inside to the outside; and a conveying pipe 20 is rotatably connected to the front end of the drive roller 12. The interior of the conveying pipe 20 is in communication with the interior of the conveying cavity 18. The end of the conveying pipe 20 away from the drive roller 12 is sealed to the outer wall of the water pipe 4. The sprayed water can be used to rinse the interior of the filter hole 1 and to wash the sludge on the wall of the scraper 21 to prevent the accumulation of sludge.

[0048] Both sets of sludge storage structures include a second sludge storage tank 22 sealed to the outer wall of the filter box 7 at the corresponding connection groove 9; a sealing baffle 23 located at the bottom of the second sludge storage tank 22 and capable of being opened and closed, with the sealing baffle 23 and the second sludge storage tank 22 sealed together, allowing for periodic separation of the sealing baffle 23 and the second sludge storage tank 22 to clean the sludge inside the second sludge storage tank 22; a corrugated pipe 24 located at the bottom of the sealing baffle 23 and sealed to the outer wall of the filter box 7; and a filter plate 25 located at the upper edge inside the corrugated pipe 24 for filtering. The plate 25 has uniformly distributed filter holes. The mixed liquid after rinsing will be stored inside the sludge storage tank 22, while the clean water will enter the corrugated pipe 24 through the filter holes and finally be discharged into the filter box 7. In this embodiment, by replacing the air source with a water source, the noise generated during operation is smaller, making the working environment more comfortable. At the same time, this solution reduces the need for air pressure and equipment, lowers the requirements for equipment during operation, and saves costs. In addition, it is only necessary to connect the delivery pipe 20 and the water supply pipe 4, which makes maintenance more convenient.

[0049] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
