Description

Technical Field

[0001] This utility model relates to the field of mixing and scraping machine technology, specifically a mixing and scraping machine for clarification tanks. Background Technology

[0002] The sludge scraper in the clarifier effectively collects and discharges settled sludge through mechanical agitation and scraping, optimizing wastewater treatment and ensuring improved water quality. For example, in a mechanically agitated clarifier, the agitator and turbine cause the influent, chemicals, and a large amount of returned sludge to come into rapid contact and mix, forming larger flocs. These flocs are then scraped by the scraper and discharged into the sludge hopper, achieving the effect of raw water clarification and separation. By controlling the sludge discharge frequency and volume appropriately, the wastewater treatment effect and system stability can be ensured, reducing equipment failures and maintenance costs. Regular inspection and maintenance of the sludge discharge equipment are necessary to ensure its normal operation, clear blockages, prevent equipment failures, and repair or replace parts as needed.

[0003] For example, the clarifier and sludge scraper disclosed in CN218011231U includes a tank body, a motor vertically mounted at the upper end of the tank body, a rotating shaft vertically mounted inside the tank body with its upper end extending through the tank body end cover and connected to the motor rotor, a sludge discharge pipe at the bottom of the tank body, and a moving shaft vertically mounted inside the tank body.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the mixing and scraping machine not only realizes the convenient movement of the mixing and scraping machine to mix at different positions and heights, but also facilitates the switching between multiple clarification chambers, avoids setting the same structure for each clarification chamber, reduces the production cost of enterprises, and prevents deviation during the mixing process, thus improving the convenience of the mixing and scraping machine in scraping the sludge on the inner wall of the clarification chamber.

[0016] (1) The electric wheel slides inside the track. The electric wheel drives the irregular frame, U-shaped frame, first electric push rod, friction block, support frame, cover plate, rotating shaft, agitator, rotating frame and scraper to move. When it moves to the body of the clarification tank to be stirred, the first electric push rod drives the friction block to move, so that the friction block contacts the track.

This facilitates the convenient movement of the position and height for stirring. It realizes the convenient movement of the stirring scraper for stirring. It facilitates the switching between multiple sets of clarification tanks. It avoids setting the same structure for each set of clarification tanks and reduces the production cost of the enterprise.

[0017] (2) When it is necessary to clamp the clarification chamber body, multiple sets of clarification chamber bodies are moved sequentially between multiple sets of side plates. The third electric push rod drives the support plate to move, and the support plate drives the arc-shaped clamping plate to move, clamping the clarification chamber body. This facilitates the stable clamping of the clarification chamber, realizes the convenient and stable clamping of the clarification chamber by the mixing scraper, prevents deviation during the mixing process, and improves the convenience of clamping the mixing scraper.

[0018] (3) The stepper motor drives the rotating shaft to rotate, which in turn drives the agitator and the rotating frame to rotate. The agitator fully stirs the mixture inside the clarification chamber. The rotating frame drives the spring to rotate, which in turn drives the scraper to rotate. Under the elastic support of the spring, the scraper elastically scrapes the clarification chamber body to remove impurities from the inner wall of the clarification chamber body. This facilitates the easy scraping of sludge from the inner wall of the clarification chamber, thus improving the convenience of the agitator scraper for scraping sludge from the inner wall of the clarification chamber.

[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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0030] Please see Figure 1-9This utility model provides an embodiment of a clarifier and sludge scraper, comprising a track 1 and a U-shaped frame 10. The U-shaped frame 10 is arranged outside the track 1, and a support frame 2 is arranged outside the U-shaped frame 10. A cover plate 3 is arranged outside the support frame 2, and multiple sets of clarifier bodies 4 are arranged at equal intervals outside the cover plate 3. A bottom plate 5 is symmetrically arranged outside the clarifier bodies 4, and four sets of side plates 6 are installed at equal intervals on the top of each bottom plate 5. A support shaft 7 is arranged inside the track 1, and electric wheels 8 are movably installed on both sides of the support shaft 7. The electric wheels 8 are slidably connected to the track 1. A shaped frame 9 is fitted at the center of the support shaft 7, extending to the outside of the track 1. The frame 9 is connected to the U-shaped frame 10. A first electric push rod 11 is installed on both sides of the U-shaped frame 10. A friction block 12 is installed at the output end of the first electric push rod 11. The first electric push rod 11 contacts the track 1 through the friction block 12. A second electric push rod 13 is installed at the bottom of the U-shaped frame 10. The output end of the second electric push rod 13 is connected to the support frame 2. A servo motor 14 is installed at the top of the support frame 2. A threaded rod 15 is installed at the output end of the servo motor 14. The threaded rod 15 extends into the interior of the support frame 2 and is movably connected to it. A threaded block 16 is fitted on the surface of the threaded rod 15. The threaded rod 15 and the threaded block 16 are threadedly connected. The threaded block 16 is connected to the cover plate 3.

[0031] When using the clarifier and sludge scraper, the electric wheel 8 is turned on. Supported by the support shaft 7, the electric wheel 8 slides inside the track 1.

When it moves above the designated clarifier body 4, the two sets of first electric push rods 11 are turned on. Supported by the U-shaped frame 10, the first electric push rods 11 drive the friction block 12 to move, so that the friction block 12 contacts the track 1, which to a certain extent prevents lateral movement of the agitator during operation. The servo motor 14 is turned on. Supported by the support frame 2, the servo motor 14 drives the threaded rod 15 to rotate. With the threaded connection between the threaded rod 15 and the threaded block 16, the threaded rod 15 drives the threaded block 16. The threaded block 16 moves the cover plate 3, rotating shaft 18, agitator 19, rotating frame 20, and scraper 23 down to the interior of a set of clarification tank bodies 4 for stirring. This facilitates convenient movement and height for stirring, ensuring thorough mixing of sewage, sludge, and chemicals. After stirring is completed inside a set of clarification tank bodies 4, the agitator 19, rotating frame 20, and scraper 23 move to the next set of clarification tank bodies 4 for operation. This allows for operation on multiple sets of clarification tank bodies 4, shortening the switching time between each set and avoiding the need for identical structures in each set, thus reducing production costs for enterprises. This system enables convenient movement and height for stirring by the mixing and scraping machine, facilitating switching between multiple clarification tanks, avoiding the need for identical structures in each set, and reducing production costs for enterprises.

[0032] The top of each side plate 6 is movably mounted with a first shaft 24, and the surface of each first shaft 24 is fitted with a third electric push rod 25.

[0033] The output end of the third electric push rod 25 is equipped with a support plate 26, and the side of the support plate 26 away from the third electric push rod 25 is equipped with an arc-shaped clamp 27.

[0034] When it is necessary to clamp the clarification chamber body 4, multiple sets of clarification chamber bodies 4 are moved sequentially between multiple sets of side plates 6. The third electric push rod 25 is opened. Under the support of the first shaft 24, the third electric push rod 25 drives the support plate 26 to move.

[0036] A stirrer 19 is mounted on the surface of the rotating shaft 18, and a rotating frame 20 is mounted on the surface of the rotating shaft 18 outside the stirrer 19.

[0037] Three sets of equally spaced moving wheels 21 are movably installed at the bottom of the clarification chamber body 4, and multiple sets of equally spaced springs 22 are installed on the side wall of the rotating frame 20.

[0038] A scraper 23 is installed on the side of the spring 22 away from the rotating frame 20, and the scraper 23 is slidably connected to the clarification tank body 4;

[0039] When it is necessary to stir the inside of the clarification chamber body 4, the stepper motor 17 is turned on. With the support of the cover plate 3, the stepper motor 17 drives the rotating shaft 18 to rotate. The rotating shaft 18 drives the agitator 19 and the rotating frame 20 to rotate. The agitator 19 stirs the inside of the clarification chamber body 4 thoroughly. The rotating frame 20 drives the spring 22 to rotate. The spring 22 drives the scraper 23 to rotate. With the elastic support of the spring 22, the scraper 23 elastically scrapes against the clarification chamber body 4 to remove impurities from the inner wall of the clarification chamber body 4. This facilitates the convenient scraping of sludge from the inner wall of the clarification chamber, and improves the convenience of the agitator scraper for scraping sludge from the inner wall of the clarification chamber.

[0040] Working principle: When using the clarifier and sludge scraper, the electric wheel 8 slides inside the track 1, driving the irregular frame 9, U-shaped frame 10, first electric push rod 11, friction block 12, support frame 2, cover plate 3, rotating shaft 18, agitator 19, rotating frame 20, and scraper 23 to move. When it moves above the designated clarifier body 4, the first electric push rod 11 drives the friction block 12 to move, making the friction block 12 contact the track 1, which to some extent prevents lateral movement of the agitator during operation. The servo motor 14 drives the threaded rod 15 to rotate, which in turn drives the threaded block 16 to move. The threaded block 16 then drives the cover plate 3, rotating shaft 18, agitator 19, rotating frame 20, and scraper 23 to descend into the clarifier body 4 for agitation. When the clarification silo body 4 is clamped, multiple sets of clarification silo bodies 4 are moved sequentially between multiple sets of side plates 6. The third electric push rod 25 drives the support plate 26 to move, and the support plate 26 drives the arc-shaped clamping plate 27 to move, clamping the clarification silo body 4. When it is necessary to stir the inside of the clarification silo body 4, the stepper motor 17 drives the rotating shaft 18 to rotate. The rotating shaft 18 drives the agitator 19 and the rotating frame 20 to rotate. The agitator 19 stirs thoroughly inside the clarification silo body 4. The rotating frame 20 drives the spring 22 to rotate, and the spring 22 drives the scraper 23 to rotate. Under the elastic support of the spring 22, the scraper 23 elastically scrapes against the clarification silo body 4, scraping away impurities in the inner wall of the clarification silo body 4. This facilitates the convenient scraping of sludge from the inner wall of the clarification silo, thus completing the operation of the stirring scraper.
