Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, specifically a sludge scraping device for sedimentation tanks. Background Technology

[0002] In current technology, sewage sedimentation tanks are equipped with sludge scrapers. These scrapers are used to remove sludge from the bottom of the sedimentation tank. Sludge scrapers are mainly divided into rotary scrapers or truss scrapers. Truss scrapers mainly include a truss, a base, a motor, wheels, and scrapers installed at the bottom of the truss. Steel rails connected to the wheels are installed on the ground. The motor on the base drives the wheels to rotate, thereby moving the scraper.

[0003] However, existing sludge scrapers cannot adjust the thickness of the scraped sludge during use, which leads to greater scraping resistance and difficulty in scraping high-density sludge. Therefore, a sludge scraping device for sedimentation tanks is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a sludge scraping device for sedimentation tanks.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The sedimentation tank sludge scraping device of this utility model includes a truss; both ends of the truss are fixedly connected to a base, and multiple traveling wheels are rotatably connected to the base; a reduction motor is fixedly connected to the truss, and the output end of the reduction motor is fixedly connected to the traveling wheels; a winch is fixedly connected to the side of the truss; a steel cable is installed on the winch; a bracket is fixedly connected to the bottom end of the steel cable; the bracket is located below the truss; a scraper is installed at the bottom of the truss; and a support assembly is installed between the truss and the bracket.

[0006] Preferably, the support assembly includes multiple guide posts and sliding seats. The multiple guide posts are fixed to the bottom of the truss, and the sliding seats are fixed to the top of the support and at corresponding positions of the guide posts. Through holes are provided at corresponding positions of the sliding seats and guide posts, and the guide posts pass through the through holes and are slidably connected to them.

[0007] Preferably, a sludge suction hose is fixedly connected to the side of the support, the bottom end of the sludge suction hose is located above the scraper, and a sludge screw pump is fixedly connected to the bottom of the truss, with the suction end of the sludge screw pump and the sludge suction hose being fixedly connected.

[0008] Preferably, multiple scrapers are provided, and the multiple scrapers are fixed to the bottom of the bracket, and the scrapers are arranged in a V-shape.

[0009] Preferably, a mud-drawing pipe is fixedly connected inside the scraper, the top end of the mud-drawing pipe is fixedly connected to the bottom end of the mud-suction hose, and an opening is provided at the bottom of the mud-suction hose.

[0010] Preferably, the bottom of the truss is fixedly connected to a support, and the bottom of the support is rotatably connected to a rope pulley, with the steel cable mounted on the rope pulley.

[0011] The advantages of this utility model are:

[0012] 1. This utility model comprises a truss, base, traveling wheels, a geared motor, a winch, steel cable, a support frame, and a scraper. In use, the traveling wheels are mounted on steel rails on the ground. The output shaft of the geared motor is connected to the traveling wheels, which drive the wheels to rotate, allowing them to travel on the steel rails. This movement of the truss moves the support frame and scraper below to scrape away sludge. During use, the winch is started, and it winds up the steel cable to lift the support frame upwards. The support frame then moves the scraper at the bottom upwards, allowing adjustment of the scraper height and thus the thickness of the scraped sludge. For dense sludge, multiple layers can be scraped to reduce scraping resistance.

[0013] 2. This utility model, by setting up a sludge suction hose and a sludge screw pump, allows for easy operation when the sludge screw pump is started. The bottom end of the sludge suction hose is positioned above the scraper, and a negative pressure is then created above the scraper through the sludge suction hose. This negative pressure is used to extract the sludge scraped off by the scraper, and then the sludge is pumped out by the sludge screw pump, facilitating the discharge and cleaning of the sludge and reducing walking resistance.

[0024] In use, the traveling wheel 14 is installed on the steel rail on the ground. The output shaft of the reduction motor 13 is connected to the traveling wheel 14. The reduction motor 13 can drive the traveling wheel 14 to rotate, so that the traveling wheel 14 can travel on the steel rail, thereby driving the truss 11 to move. The movement of the truss 11 drives the support 15 and scraper below to move to scrape off the sludge. During use, the winch 16 is started and the winch 16 winds up the steel cable 17, thereby lifting the support 15 upward through the steel cable 17. The support 15 drives the scraper 3 at the bottom to move upward, thereby adjusting the height of the scraper 3, so as to easily adjust the thickness of the scraped sludge. For high-density sludge, it can be scraped in multiple layers to reduce scraping resistance.

[0025] During the adjustment process, the guide post 21 and the sliding seat 22 are slidably connected, which can guide the up and down movement of the support 15, thereby enabling the scraper 3 to move and scrape off the sludge when walking.

[0026] Furthermore, such as Figure 1-5 As shown, a sludge suction hose 41 is fixedly connected to the side of the bracket 15, and the bottom end of the sludge suction hose 41 is located above the scraper 3. A sludge screw pump 42 is fixedly connected to the bottom of the truss 11, and the suction end of the sludge screw pump 42 is fixedly connected to the sludge suction hose 41.

[0027] When in use, start the sludge screw pump 42. The bottom end of the sludge suction hose 41 is located above the scraper 3. Then, a negative pressure is formed above the scraper 3 through the sludge suction hose 41. The sludge scraped by the scraper 3 is extracted by the negative pressure and then pumped by the sludge screw pump 42 to facilitate the discharge and cleaning of sludge and reduce the resistance of walking.

The reduction motor 13 can drive the walking wheel 14 to rotate, so that the walking wheel 14 can walk on the steel rail, thereby driving the truss 11 to move. The movement of the truss 11 drives the support 15 and scraper below to move to scrape off the sludge. During use, the winch 16 is started, and the winch 16 winds up the steel cable 17, thereby lifting the support 15 upward through the steel cable 17. The support 15 drives the scraper 3 at the bottom to move upward, thereby adjusting the height of the scraper 3, so as to easily adjust the thickness of the scraped sludge. For high-density sludge, it can be scraped in multiple layers to reduce scraping resistance.

[0032] During adjustment, the guide post 21 and the sliding seat 22 are slidably connected, thereby guiding the up-and-down movement of the support 15. This allows the scraper 3 to move and scrape away sludge during movement. In use, the sludge screw pump 42 is started, with the bottom end of the suction hose 41 positioned above the scraper 3. A negative pressure is then created above the scraper 3 through the suction hose 41, using this negative pressure to extract the sludge scraped by the scraper 3. The sludge is then pumped out by the sludge screw pump 42 for easy discharge and cleaning, and to reduce... To reduce the resistance to movement, multiple scrapers 3 are provided during use.
