Description

Technical fields:

[0001] This utility model relates to the field of water treatment equipment technology, and specifically to a sludge scraping device for an adjustable horizontal flow tank. Background technology:

[0002] Horizontal flow sedimentation tanks are structures used to remove suspended solids from water and are widely used in water supply treatment. Because suspended solids settle to the bottom of the tank to form sludge, a sludge scraper is needed to scrape the sludge from the bottom to the suction port, where it is then discharged from the tank via siphon suction. Currently, such as Figure 1 The diagram shows a traditional sludge discharge scheme for a horizontal flow sedimentation tank, which includes a sedimentation tank (a), a sludge truck (b), a siphon pipe (c), a sludge scraper (d), and a water collection trough column (e).

[0003] Because existing sludge removal trucks mostly have fixed scraper designs, after cleaning, the trucks tend to scrape the sludge from the bottom of the sedimentation tank back during the return trip. This scraping often disturbs the floating sludge, affecting the sludge removal efficiency and the quality of the treated water. In existing horizontal flow sedimentation tanks, several supporting columns already exist. The scraper blades cannot effectively scrape the sludge covered by these columns to the suction port for suction, resulting in a large accumulation of sludge on the bottom of the tank. Therefore, the scraping device is not thorough enough in removing sludge from the bottom of the tank and cannot effectively complete the removal work. Thus, it is necessary to develop a sludge scraping device for horizontal flow sedimentation tanks that can thoroughly remove sludge with a high scraping effect.

[0004] In view of the above, the inventors propose the following technical solution. Utility Model Content:

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an adjustable sludge scraping device for a horizontal flow pool.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an adjustable sludge scraping device for a horizontal flow tank, comprising: a scraper plate hinged to the bottom of a trolley sludge discharge pipe support frame and extending to the bottom of a sedimentation tank; a cylinder disposed at the upper end of the trolley sludge discharge pipe support frame and used to drive the scraper plate to rotate and swing; a lifting rod and an adjusting connecting rod disposed between the cylinder and the scraper plate and capable of adjusting length; a floating joint disposed between the adjusting connecting rod and the cylinder; and a first U-shaped groove buckle disposed between the lifting rod and the scraper plate, wherein the scraper plate and the trolley sludge discharge pipe support frame are hinged by a second U-shaped groove buckle and a third U-shaped groove buckle.

[0007] Furthermore, in the above technical solution, the first U-shaped groove buckle, the second U-shaped groove buckle, and the third U-shaped groove buckle are arranged in an inverted triangle and welded to the scraper plate. One end of the lifting rod extends into the first U-shaped groove buckle and is connected by a pin. The bottom of the trolley mud discharge pipe support frame is provided with at least two lugs that can extend into the second U-shaped groove buckle and the third U-shaped groove buckle, and are connected to the second U-shaped groove buckle and the third U-shaped groove buckle by pins passing through the lugs.

[0008] Furthermore, in the above technical solution, the other end of the lifting rod is threadedly connected to the adjusting connecting rod, and the other end of the adjusting connecting rod is connected to the piston of the cylinder through a floating joint. The extension and retraction length of the lifting rod is adjusted by the adjusting connecting rod, and the piston rod and load eccentricity are absorbed by the floating joint.

[0009] Furthermore, in the above technical solution, the scraper blade is arc-shaped, and the edge of the scraper blade is provided with a rubber plate.

[0010] Furthermore, in the above technical solution, the sludge discharge pipe support frame of the traveling vehicle is provided with a support seat for floating installation of the cylinder.

[0011] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0012] 1. This utility model employs a movable scraper device installed on the sludge discharge truck. During the return stroke, the scraper is retracted by a cylinder, preventing disturbance to the floating sludge. This solution requires only retrofitting and does not require the construction of new structures. Furthermore, it is novel in design and applicable to the retrofitting of siphon truss-type sludge discharge trucks in horizontal flow sedimentation tanks of waterworks in my country.

[0013] 2. This utility model can quickly scrape the sludge off the bottom of the pool and collect the sludge at the bottom of the pool to the sludge suction port, and then discharge it from the sludge discharge port. The length of the scraper can be adjusted by adjusting the connecting rod so that the scraper can be rotated to fit closely to the bottom of the pool, thereby achieving the effect of cleaning the sludge and extending the service life of the scraper.

[0020] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0021] See Figures 1 to 6 As shown, an adjustable sludge scraping device for a horizontal flow tank includes: a scraper 8 hinged to the bottom of a trolley sludge discharge pipe support frame 1 and extending to the bottom of a sedimentation tank 10; a cylinder 3 located at the upper end of the trolley sludge discharge pipe support frame 1 and used to drive the scraper 8 to rotate and swing; a lifting rod 6 and an adjusting connecting rod 5 located between the cylinder 3 and the scraper 8 and capable of adjusting length; a floating joint 4 located between the adjusting connecting rod 5 and the cylinder 3; and a first U-shaped groove buckle 71 located between the lifting rod 6 and the scraper 8. The scraper 8 and the trolley sludge discharge pipe support frame 1 are hinged together by a second U-shaped groove buckle 72 and a third U-shaped groove buckle 73. The cylinder 3 uses the lifting rod 6 to swing and rotate the scraper 8, so that during cleaning, the scraper 8 is swung to a vertical position to contact the bottom surface of the sedimentation tank 10 to collect sludge. On the return trip, the cylinder 3 pulls the scraper 8 to rotate to a horizontal position, so that the floating sludge is not disturbed during the return trip, thus improving the cleaning effect.

[0022] The first U-shaped groove buckle 71, the second U-shaped groove buckle 72, and the third U-shaped groove buckle 73 are arranged in an inverted triangle and welded to the scraper plate 8. One end of the lifting rod 6 extends into the first U-shaped groove buckle 71 and is connected by a pin. The bottom of the trolley mud discharge pipe support frame 1 is provided with at least two lugs that can extend into the second U-shaped groove buckle 72 and the third U-shaped groove buckle 73, and are connected to the second U-shaped groove buckle 72 and the third U-shaped groove buckle 73 by a pin passing through the lugs.

[0023] The other end of the lifting rod 6 is threadedly connected to the adjusting connecting rod 5, and the other end of the adjusting connecting rod 5 is connected to the piston of the cylinder 3 through the floating joint 4. The extension and retraction length of the lifting rod 6 is adjusted by the adjusting connecting rod 5, and the piston rod and load eccentricity are absorbed by the floating joint 4. The trolley mud discharge pipe support frame 1 is provided with a support seat 2 for floating installation of the cylinder 3.

[0024] The scraper blade 8 is arc-shaped, and its edges are fitted with rubber plates 11. Using rubber plates 11 at the edges of the scraper blade 8 ensures a tight fit and facilitates easy replacement after wear, reducing costs and extending its lifespan. When the rubber plates 11 wear down, the connecting rod 6 can be adjusted to ensure they remain in close contact with the bottom surface of the sedimentation tank 10, thus achieving a clean scraping effect and extending the service life of the scraper blade 8.

[0025] In summary, this utility model fully utilizes existing structures such as sedimentation tanks in waterworks, requiring no new construction but only retrofitting. It features a novel design, low sludge discharge water consumption, and provides a sludge scraping device for horizontal flow sedimentation tanks. This device quickly scrapes sludge from the bottom of the tank, collects it at the bottom suction port, and discharges it from the discharge port. The length of the scraper can be adjusted by changing the connecting rod, allowing the scraper to rotate and adhere closely to the bottom of the tank, achieving a clean scraping effect and extending the scraper's lifespan. Furthermore, a movable scraper is installed on the sludge truck; the scraper is retracted by a cylinder during the return stroke, preventing disturbance to floating sludge. This design is suitable for retrofitting siphon sludge discharge trucks in water treatment plant sedimentation tanks. This solution eliminates the influence of manual experience-based settings on the system's sludge discharge effect. It requires no new construction but only retrofitting, and features a novel design with low sludge discharge water consumption. By setting reasonable concentration parameters, it enables refined sludge discharge and is suitable for retrofitting siphon truss-type sludge discharge trucks in horizontal flow sedimentation tanks of waterworks in my country.
