Description

Technical Field

[0001] This utility model relates to the field of sewage tank technology, specifically to a chemical sewage tank that is easy to clean. Background Technology

[0002] Wastewater discharge equipment is frequently used in wastewater treatment. This equipment typically includes a tank for collecting wastewater and a pump installed on the tank to discharge the wastewater. The container used for discharge is the most crucial component. However, during the discharge of wastewater into the container, various impurities and filth easily adhere to the inner walls and bottom plate. To ensure proper discharge, cleaning is necessary. Existing wastewater discharge equipment lacks self-cleaning capabilities. After each period of wastewater discharge, manual cleaning of the inner walls and bottom plate is required, which is time-consuming and labor-intensive. Furthermore, the cleaning process cannot simultaneously clean the inner walls and bottom plate, nor can it effectively rinse the equipment, thus hindering its efficiency and practicality.

[0003] To address the aforementioned technical problems, patent document CN222042719U discloses a sewage discharge device with a self-cleaning structure. This self-cleaning sewage discharge device includes a sewage tank and a cleaning frame. The cleaning frame is threadedly slidably connected within the sewage tank. The cleaning frame is equipped with a cleaning scraper and a cleaning nozzle, which are fixedly connected to the cleaning frame. Through the coordinated use of the threaded screw, cleaning frame, cleaning scraper, and cleaning nozzle, the self-cleaning sewage discharge device can scrape away impurities adhering to the inner walls and bottom plate of the sewage tank after sewage discharge using the cleaning frame and cleaning scraper. Simultaneously, it can effectively flush the sewage tank, avoiding the time and manpower required for manual cleaning of adhering impurities. However, when the sludge thickness at the bottom of the sewage tank is significant, the bottom of the cleaning frame alone is insufficient to effectively scrape it off. Increasing the height of the cleaning frame's bottom for sludge scraping also scrapes away residual wastewater, resulting in considerable resistance during the frame's movement. Therefore, a chemical sewage tank design is needed that can adjust the scraping depth based on the sludge thickness and wastewater depth at the bottom of the tank. Utility Model Content

[0004] The main purpose of this utility model is to provide a chemical wastewater treatment tank that can adjust the scraping depth according to the thickness of sludge and the depth of sewage at the bottom of the tank.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A chemical wastewater treatment tank that is easy to clean includes a tank body, a U-shaped scraper frame that is slidably installed inside the tank body, the outer edge of the scraper frame contacting a sliding plate on the inner wall of the tank body, and power components that can drive the scraper frame to move within the tank body on both sides of the upper end of the tank body. A rotating shaft is rotatably connected to each of the two vertical parts of the scraper frame, and the rotating shaft is fixedly connected to a scraper. The lower end of the scraper is in contact with the upper end of the straight part of the scraper frame. A drive unit that can drive the rotating shaft to rotate is installed on the vertical part of the scraper frame, and the upper ends of the two vertical parts of the scraper frame are fixedly connected by a connecting rod.

[0007] Specifically, the upper end face of the straight part of the scraper frame is an upper arc surface, which curves downward in the middle. The lower end face of the scraper is a lower arc surface, which curves downward in the middle. The lower arc surface of the scraper is in contact with the upper arc surface. The upper arc surface, the lower arc surface and the rotating shaft are concentric. The two ends of the scraper slide in contact with the opposite end faces of the two vertical parts of the scraper frame.

[0008] Specifically, the drive unit includes a lower gear fixedly connected to the rotating shaft concentrically. A rectangular groove is provided on the vertical part of the scraper frame, and the rotating shaft passes through the rectangular groove on one side. The lower gear is located in the rectangular groove. Protective covers are fixedly and sealed on both sides of the vertical part of the scraper frame, forming an isolation cavity between the protective covers and the vertical part of the scraper frame. The isolation cavity is connected to the rectangular groove. The protective covers can prevent sewage in the pool from entering the isolation cavity and the rectangular groove. A fixing block is fixed inside the protective cover. A lower rack is slidably arranged in the vertical direction of the fixing block. The lower rack meshes with the lower gear. A lower telescopic rod is fixed on the scraper frame above the lower rack. The lower telescopic rod is vertically arranged and located in the isolation cavity. One end of the lower telescopic rod is fixedly connected to the scraper frame, and the lower end of the lower telescopic rod is fixedly connected to the upper end of the lower rack.

[0009] Specifically, the scraper has a groove that extends through the upper part of the scraper. The scraper has two vertical grooves that communicate with the groove. Two wedges are slidably arranged in the groove. The inclined surfaces of the two wedges are arranged opposite each other. The opposite ends of the two wedges are connected by multiple double-ended telescopic rods. The middle part of the double-ended telescopic rods is fixedly connected to the scraper, and the two ends of the double-ended telescopic rods are fixedly connected to the two wedges respectively.

[0010] Specifically, the wedge plate makes sliding contact with the groove wall.

[0011] Specifically, a downward protruding lower cavity is provided on one side of the lower end of the pool body. An inclined guide plate is fixed inside the lower cavity, and a sludge pump is installed inside the lower cavity. The sludge pump is located above the downward inclined side of the guide plate. A sewage pipe is fixedly connected to the outlet of the sludge pump, and the sewage pipe is fixedly connected to the pool body through multiple support plates.

[0012] Specifically, the power assembly includes two power units, which are respectively fixed on both sides of the upper end of the pool body. Each power unit includes a fixing strip with a long groove. An upper rack is fixed in the long groove, and a slide is fixed at the upper end of the fixing strip. The length direction of the fixing strip is parallel to the length direction of the pool body. The upper rack, the long groove, the slide, and the fixing strip are parallel. A slide plate is slidably engaged on the slide plate. The slide plate is fixedly connected to the vertical part of the scraper frame. A motor is fixed on the vertical part of the scraper frame. An upper gear is concentrically fixed on the output shaft of the motor. The upper gear is located in the long groove and meshes with the upper rack.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. Through the coordinated action of the scraper frame and the power unit, the scraper frame moves smoothly on the inner wall of the tank, effectively scraping off sludge and guiding it to the lower chamber; the design of the guide plate and sludge pump ensures that the sludge is quickly collected and extracted, reducing residue and improving overall cleaning efficiency.

[0015] 2. The drive unit allows the scraper to rotate and adjust the scraper angle when the sludge thickness is large, ensuring that the scraper fits the arc surface of the scraper frame and enhancing the scraping ability of the sludge layer; the vertical trough and wedge plate system are further optimized. When there is sewage above the sludge layer, the position of the wedge plate is adjusted to form a sewage flow area. The sewage above the sludge layer can pass through the sewage flow area, reducing the movement resistance of the scraper and improving the adaptability of the cleaning process to different working conditions.

[0016] 3. The protective cover and isolation chamber structure effectively isolate sewage, preventing it from entering transmission components such as gears and racks; the waterproof treatment of the double-end telescopic rods enhances durability, reduces the risk of corrosion, ensures long-term stable operation of the equipment, and reduces maintenance frequency.

[0017] 4. The power components adopt a standardized design to achieve uniform movement of the scraper frame; the setting of connecting rods and fixing blocks simplifies the structure and facilitates installation and disassembly; the overall design reduces manual intervention, making the cleaning process more automated and improving the daily maintenance efficiency of the sewage tank.

[0029] 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.

[0030] Example 1: Refer to Figures 1-10 As shown, a chemical wastewater treatment tank that is easy to clean includes a tank body 1. A downwardly protruding lower cavity 15 is provided on one side of the lower end of the tank body 1. An inclined guide plate 16 is fixed inside the lower cavity 15. A sludge pump 14 is installed inside the lower cavity 15. The sludge pump 14 is located above the downwardly inclined side of the guide plate 16. A sewage pipe 12 is fixedly connected to the outlet of the sludge pump 14. The sewage pipe 12 is fixedly connected to the tank body 1 through multiple support plates 13.

[0031] A U-shaped scraper frame 6 is slidably installed inside the pool body 1. The outer edge of the scraper frame 6 contacts the sliding plate on the inner wall of the pool body 1. Power components capable of driving the scraper frame 6 to move inside the pool body 1 are provided on both sides of the upper end of the pool body 1.

[0032] like Figures 1-4 , Figure 6 and Figure 8As shown, the power assembly includes two power units, which are fixed on both sides of the upper end of the pool body 1.

[0033] The power unit includes a fixed bar 2, on which a long groove 10 is formed. An upper rack 4 is fixed in the long groove 10. A slide bar 3 is fixed at the upper end of the fixed bar 2. The length direction of the fixed bar 2 is parallel to the length direction of the pool body 1. The upper rack 4, the long groove 10, the slide bar 3 and the fixed bar 2 are parallel. A slide plate 5 is slidably engaged on the slide bar 3. The slide plate 5 is fixedly connected to the vertical part of the scraper frame 6. A motor 7 is fixed on the vertical part of the scraper frame 6. An upper gear 8 is concentrically fixed on the output shaft of the motor 7. The upper gear 8 is located in the long groove 10 and meshes with the upper rack 4.

[0034] Simultaneously, the motors 7 on both sides are started, and the output shafts of the motors 7 on both sides rotate at the same speed and in the same direction. Under the meshing action of the upper gear 8 and the upper rack 4, and the sliding engagement action of the slide bar 3 and the slide plate 5, the scraper frame 6 can move along the length of the pool body 1. The scraper frame 6 can scrape the sludge on the inner wall of the pool body 1 into the lower cavity 15.

[0035] A rotating shaft 22 is rotatably connected to each of the two vertical parts of the scraper frame 6. The rotating shaft 22 is fixedly connected to the scraper 11, and the lower end of the scraper 11 contacts the upper end of the straight part of the scraper frame 6.

[0036] like Figure 3 and Figure 5 As shown, the upper end face of the straight part of the scraper frame 6 is an upper arc surface, which curves downward in the middle. The lower end face of the scraper 11 is a lower arc surface, which curves downward in the middle. The lower arc surface of the scraper 11 is in contact with the upper arc surface. The upper arc surface, the lower arc surface and the rotating shaft 22 are concentric. The two ends of the scraper 11 slide in contact with the opposite end faces of the two vertical parts of the scraper frame 6.

[0037] A drive unit capable of driving the rotating shaft 22 to rotate is provided on the vertical part of the scraper frame 6, and the upper ends of the two vertical parts of the scraper frame 6 are fixedly connected by the connecting rod 9.

[0038] like Figure 3 , Figure 6 , Figure 7 , Figure 9 and Figure 10As shown, the drive unit includes a lower gear 23 concentrically fixedly connected to the rotating shaft 22. A rectangular groove 21 is provided on the vertical part of the scraper frame 6. The rotating shaft 22 passes through the rectangular groove 21 on one side. The lower gear 23 is located in the rectangular groove 21. Protective covers 25 are fixedly and sealed on both sides of the vertical part of the scraper frame 6. An isolation cavity is formed between the protective cover 25 and the vertical part of the scraper frame 6. The isolation cavity is connected to the rectangular groove 21. The protective cover 25 can prevent sewage in the pool 1 from entering the isolation cavity and the rectangular groove 21. A fixing block 26 is fixed inside the protective cover 25. A lower rack 24 is slidably arranged in the vertical direction of the fixing block 26. The lower rack 24 meshes with the lower gear 23. A lower telescopic rod 27 is fixed on the scraper frame 6 above the lower rack 24. The lower telescopic rod 27 is arranged vertically and located in the isolation cavity. One end of the lower telescopic rod 27 is fixedly connected to the scraper frame 6, and the lower end of the lower telescopic rod 27 is fixedly connected to the upper end of the lower rack 24.

[0039] When the sludge thickness in pool 1 is large, the lower telescopic rod 27 is activated, so that the telescopic ends of the lower telescopic rods 27 on both sides of the scraper frame 6 move in opposite directions and at the same speed. The cooperation between the lower rack 24 and the lower gear 23 enables the rotating shaft 22 to rotate. When the rotating shaft 22 rotates, it can drive the scraper 11 to rotate. When the lower arc surface of the lower end of the scraper 11 is in contact with the upper arc surface of the upper end of the straight part of the scraper frame 6, the straight part of the scraper frame 6 and the scraper 11 can be used to scrape off the sludge in the lower end of the pool 1.

[0040] After the sludge is scraped into the lower chamber 15, it is collected at the sludge pump 14 under the guidance of the guide plate 16. Starting the sludge pump 14 can extract the sludge from the lower chamber 15.

[0041] When cleaning the inner wall of the pool 1, the scraper 11 is rotated to a horizontal position by the lower telescopic rod 27 to avoid the cleaning fluid in the pool 1 exerting too much resistance on the scraper 11 when the scraper frame 6 moves.

[0042] Example 2: Based on Example 1, referring to... Figure 6 As shown, a groove 17 is formed inside the scraper 11, extending through the upper end of the scraper 11. Two vertical grooves 18 are formed on the scraper 11, communicating with the groove 17. Two wedges 19 are slidably disposed within the groove 17, with their inclined surfaces facing away from each other. The wedges 19 slide in contact with the groove wall of the groove 17. The opposite ends of the two wedges 19 are connected by multiple double-ended telescopic rods 20. The middle of the double-ended telescopic rods 20 is fixedly connected to the scraper 11, and the two ends of the double-ended telescopic rods 20 are respectively fixedly connected to the two wedges 19.

[0043] When the lower layer of the pool 1 is sludge and the upper layer is sewage, if the flat part of the scraper frame 6 and the scraper 11 are used to scrape away the sludge and sewage at the same time, the scraper 11 will be subject to the resistance of both the sludge and the sewage. Therefore, the scraper 11 will experience greater resistance during its movement.

[0044] In this embodiment, by setting two vertical grooves 18 on the scraper 11 and setting wedges 19 that cooperate with the vertical grooves 18, when the telescopic ends on both sides of the double-ended telescopic rod 20 are extended, the two wedges 19 move away from each other, and the wedges 19 gradually block the vertical groove 18 on one side of it. The part of the vertical groove 18 that is not blocked by the wedges 19 allows sewage to pass through. The part of the vertical groove 18 that is not blocked by the wedges 19 is the sewage flow area. As the two wedges 19 move away from each other, the area of ​​the sewage flow area gradually decreases, and the height of the lower end of the sewage flow area gradually increases.

[0045] When there is sewage above the sludge layer in the lower end of the tank 1, adjust the position of the wedge plate 19 so that the lower end of the sewage flow area is higher than the upper end of the sludge layer. As the scraper 11 moves with the scraper frame 6 in the tank 1, the sewage above the sludge layer can pass through the sewage flow area. When the scraper frame 6 and the scraper 11 scrape the sludge layer in the lower end of the tank 1, the resistance on the scraper 11 can be reduced.

[0046] To improve the service life of the double-ended telescopic pole 20, the double-ended telescopic pole 20 is waterproofed.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
