Abstract
Description
Technical Field
[0001] This utility model relates to the field of river ecological management, and in particular to an integrated sedimentation tank sludge removal structure for water pollution control. Background Technology
[0002] Sedimentation tanks are commonly used equipment in wastewater treatment. Common sedimentation tanks are mainly of three types: horizontal flow, vertical flow, and radial flow. Horizontal flow sedimentation tanks have a strong ability to adapt to shock loads and temperature changes, and are simple to construct and inexpensive. Therefore, horizontal flow sedimentation tanks are more commonly used in my country for treating industrial wastewater. By designing the bottom of the tank with a certain slope (usually 45°-60°), the sludge slides to the sludge discharge port at the lowest point of the tank bottom by its own gravity, thus achieving the function of guiding the sludge.
[0003] The common horizontal flow sludge scraping method involves installing scrapers inside the tank and controlling their sliding via a sliding rail on the top of the tank to scrape sludge from the bottom of the tank into the sludge storage area. Its disadvantage is that the scraper and the sliding rail are connected by a long plate, which drives the scraper to move at the bottom of the tank. This increases the height of the scraper, and the larger the scraper area, the easier it is to agitate the water flow in the tank when it moves in the water. This causes a large amount of sludge to be scattered into the water, which affects sedimentation and results in low sludge discharge efficiency. Utility Model Content
[0004] In view of the problem that the scraper is too high in the above or existing technology and easily agitates the water flow in the pool when it moves in the water, causing a large amount of sludge to be scattered into the water, thus affecting the sedimentation and resulting in low sludge discharge efficiency, this utility model is proposed.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A sludge discharge component includes a sedimentation tank body. An inlet pipe is fixedly connected to the left side of the sedimentation tank body, a drain pipe is fixedly connected to the left side of the sedimentation tank body, and a drain pipe is fixedly connected to the right side of the sedimentation tank body. Two inclined rods are fixedly connected to the inner side of the sedimentation tank body, and a drain assembly is provided outside the inclined rods. A winch body is provided at the top of the sedimentation tank body. A cleaning component includes two sludge scraper frames, which are slidably connected to the outside of the two inclined rods.
[0006] As a preferred embodiment of the integrated sedimentation tank sludge discharge structure for water pollution treatment of this utility model, the sludge discharge component includes two U-shaped blocks, which are respectively disposed outside two inclined rods. Four auxiliary rollers are rotatably connected inside each of the two U-shaped blocks. A protrusion is fixedly connected to the top of each U-shaped block. A rotary motor is fixedly connected inside the left side of the sedimentation tank body. A winding roller is fixedly connected to the output end of the rotary motor. Two steel ropes are fixedly connected to the outside of the winding roller. Two support blocks are fixedly connected to the top of the sedimentation tank body. A scraper is fixedly connected between the two U-shaped blocks. Anti-detachment blocks are fixedly connected to the inner sides of each of the two inclined rods.
[0007] As a preferred embodiment of the integrated sedimentation tank sludge removal structure for water pollution treatment of this utility model, the anti-detachment block is located on the left side of the U-shaped block, the bottom inner side of the sedimentation tank body is inclined, and the bottom of the scraper abuts against the inclined surface.
[0008] As a preferred embodiment of the integrated sedimentation tank sludge discharge structure for water pollution treatment of this utility model, the two steel ropes are respectively movably connected inside the two support blocks, and both steel ropes are wound around the outside of the winding roller.
[0009] As a preferred embodiment of the integrated sedimentation tank sludge removal structure for water pollution treatment of this utility model, the end of the steel rope away from the winding roller is fixedly connected to the protrusion, and the four auxiliary rollers roll symmetrically in pairs on the upper and lower sides of the inclined rod.
[0010] As a preferred embodiment of the integrated sedimentation tank sludge removal structure for water pollution treatment of this utility model, wherein: the scraper has a hollow groove inside, and a reinforcing rib is fixedly connected inside the hollow groove; and the two scraper frames are fixedly connected to the left side of the two U-shaped blocks.
[0011] The beneficial effects of the integrated sedimentation tank sludge removal structure for water pollution treatment of this utility model:
[0012] 1. The sludge is discharged through the sludge discharge component, which uses a steel cable to pull the scraper. The steel cable has a smaller agitation effect on the water when it is pulled, and the U-shaped block moves through the cooperation of the auxiliary roller and the inclined rod, which further reduces the agitation. This avoids the problem that conventional scrapers, which are too high, easily stir up the water flow in the tank when they move in the water, causing a large amount of sludge to be scattered into the water, thus affecting the sedimentation and resulting in low sludge discharge efficiency. This achieves a better sedimentation and separation effect for sewage.
[0013] 2. By cleaning the components, the mud on the movement path of the auxiliary roller is removed using the mud scraper frame, thereby avoiding the problem of poor scraping caused by the auxiliary roller moving unevenly, and achieving smoother scraping and enhanced mud scraping effect.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0022] Example 1, referring to Figures 1-4This is the first embodiment of the present invention. This embodiment provides an integrated sedimentation tank sludge removal structure for water pollution treatment. It can remove sludge from the slope inside the sedimentation tank without causing significant agitation to the upper clear water after sedimentation, thereby further enhancing the sedimentation effect. It includes a sludge removal component, including a sedimentation tank body 10. An inlet pipe 11 is fixedly connected to the left side of the sedimentation tank body 10, a sewage pipe 12 is fixedly connected to the left side of the sedimentation tank body 10, a drain pipe 13 is fixedly connected to the right side of the sedimentation tank body 10, two inclined rods 14 are fixedly connected to the inner side of the sedimentation tank body 10, a sewage discharge component 15 is provided on the outside of the inclined rods 14, and a winch body 16 is provided on the top of the sedimentation tank body 10.
[0023] Specifically, the winch body 16 can drive the scraper 158 to reset after scraping the sludge, so that it can be used again next time. The sewage discharge component 15 pulls the scraper 158 to discharge sludge through the steel rope 156. The steel rope 156 has a small agitation effect on the water when it is pulled, and the U-shaped block 151 moves through the cooperation of the auxiliary roller 152 and the inclined rod 14, which further reduces the agitation. This avoids the problem that the conventional scraper 158 is too high and easily stirs the water flow in the pool when it moves in the water, causing a large amount of sludge to be scattered into the water, thus affecting the sedimentation and causing low sludge discharge efficiency.
[0024] Furthermore, the sewage discharge assembly 15 includes two U-shaped blocks 151, which are respectively disposed outside the two inclined rods 14. Four auxiliary rollers 152 are rotatably connected inside the two U-shaped blocks 151. A protrusion 153 is fixedly connected to the top of the U-shaped blocks 151. A rotary motor 154 is fixedly connected inside the left side of the sedimentation tank body 10. A winding roller 155 is fixedly connected to the output end of the rotary motor 154. Two steel ropes 156 are fixedly connected to the outside of the winding roller 155. Two support blocks 157 are fixedly connected to the top of the sedimentation tank body 10. A scraper 158 is fixedly connected between the two U-shaped blocks 151. Anti-detachment blocks 159 are fixedly connected to the inner sides of the two inclined rods 14.
[0025] Among them, an anti-detachment block 159 is provided on the inner side of the left end of the diagonal bar 14 to limit the movement of the U-shaped block 151, so as to prevent the steel rope 156 from being pulled too much and causing the auxiliary roller 152 to fail to cooperate with the diagonal bar 14, thus achieving better results.
[0026] Preferably, the anti-detachment block 159 is located on the left side of the U-shaped block 151, the bottom inner side of the sedimentation tank body 10 is inclined, and the bottom of the scraper 158 abuts against the inclined surface. Two steel ropes 156 are movably connected to the inside of the two support blocks 157 respectively. Both steel ropes 156 are wound around the outside of the winding roller 155. The end of the steel rope 156 away from the winding roller 155 is fixedly connected to the protrusion 153. Four auxiliary rollers 152 roll symmetrically in pairs on the upper and lower sides of the inclined rod 14.
[0027] It should be noted that the U-shaped block 151 moves by an auxiliary roller 152 rolling outside the inclined rod 14, which makes the scraper 158 move smoothly and effortlessly, resulting in a good scraping effect while saving more effort.
[0028] In use, when it is necessary to scrape the sludge on the inclined surface inside the sedimentation tank body 10, the rotary motor 154 is started to drive the winding roller 155 to rotate (at the same time, the winch body 16 is started to reverse the winch body 16, so that the connecting rope between the winch body 16 and the scraper 158 is loosened, thus not affecting the pulling of the steel rope 156 on the protrusion 153). This causes the two steel ropes 156 to be wound around the outside of the winding roller 155, so that the steel ropes 156 pull the protrusion 153 to move, thereby causing the U-shaped block 151 to slide to the left outside the inclined bar 14, so that the scraper 158 slides along the slope inside the sedimentation tank body 10 towards the sludge storage area. The scraper 158 plays the role of scraping sludge, scraping the sludge settled on the slope to the sludge storage area. The sludge is discharged through the sewage pipe 12. The scraper 158 is low in height and can only scrape and clean the settled sludge without stirring the clear water above the sludge. This can minimize the impact of the clear water stirring on the sewage sedimentation. At the same time, the U-shaped block 151 moves slowly and stably on the lower inner side of the sedimentation tank body 10 through the auxiliary roller 152 and the inclined rod 14, which prevents the scraped sludge from being thrown up, thus making the sedimentation and separation effect of clear water and sludge better. After cleaning, the winch body 16 is started to rotate forward and the rotary motor 154 is started to rotate in the opposite direction, so that the steel cable 156 is loosened. The winch body 16 drives the scraper 158 to return to the inside of the right side of the sedimentation tank body 10, which is convenient for the next sludge scraping.
[0029] Example 2, refer to Figure 5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a cleaning component for the integrated sedimentation tank sludge discharge structure for water pollution treatment based on embodiment 1. This solves the problem of sludge accumulation outside the inclined rod 14 of the rolling path of the auxiliary roller 152, making the scraper 158 move more smoothly. It includes a cleaning component, including two scraper frames 20. The two scraper frames 20 are slidably connected to the outside of the two inclined rods 14 respectively. The scraper 158 has a hollow groove 21 inside, and a reinforcing rib 22 is fixedly connected inside the hollow groove 21. The two scraper frames 20 are fixedly connected to the left side of the two U-shaped blocks 151.
[0030] In use, a scraper frame 20 is fixed to the left side of the U-shaped block 151, and the scraper frame 20 abuts against the outside of the inclined bar 14. When the auxiliary roller 152 rolls outside the inclined bar 14, the scraper frame 20 first removes the mud on the movement path of the auxiliary roller 152, thereby avoiding the problem of poor scraping by the scraper 158 caused by the auxiliary roller 152 not moving smoothly. At the same time, the scraper 158 has a hollow groove 21 inside, which reduces the weight of the scraper 158 and makes the scraper 158 move more effortlessly. The hollow groove 21 is fixed with a reinforcing rib 22, which reduces the weight of the scraper 158 while increasing its strength, avoiding the scraper 158 bending due to the impact of movement, and further enhancing the mud removal effect of the scraper 158.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
