DETAILED DESCRIPTION

[0032] The present application provides a sedimentation tank scraping and suction sludge machine integrating cyclone separation and concentration self-adaptation as shown in Figures 1-9 The truss 1 is provided below the truss 1 with a scraper 2, and the truss 1 is further fixedly connected with a cyclone separator 29, the cyclone separator 29 is connected with a submersible sewage pump 24, the submersible sewage pump 24 is connected with a suction pipe 10, the suction pipe 10 is in communication with the feed end of the submersible sewage pump 24, the discharge end of the submersible sewage pump 24 is in communication with the cyclone separator 29, the bottom end of the cyclone separator 29 is communicated with a sludge discharge pipeline 28, the end of the sludge discharge pipeline 28 away from the cyclone separator 29 extends to the outside of the sedimentation tank, and the top end of the cyclone separator 29 is communicated with an overflow pipeline 27.

[0033] The present embodiment can realize instant suction and efficient separation of sludge by integrating the cyclone separator 29 and the submersible sewage pump 24 in the sedimentation tank scraping and suction sludge machine, the cyclone separator 29 utilizes centrifugal force to rapidly separate the mixed liquid sucked by the suction pipe, the high-concentration sludge separated out is discharged to the outside of the sedimentation tank through the sludge discharge pipeline 28, and the clarified liquid is recycled or discharged through the overflow pipeline 27, thereby significantly improving the efficiency and concentration self-adaptation capability of sludge treatment, reducing the subsequent treatment load, and optimizing the operation effect of the sedimentation tank.

[0034] As an embodiment, the truss 1 is arranged at the top of the sedimentation tank, and since the scraper 2 is arranged below the truss 1, when the scraper 2 is used to clean the sludge inside the sedimentation tank, the scraper 2 is attached to the bottom of the sedimentation tank and pushes and scrapes the sludge on the bottom of the sedimentation tank during movement. Considering that the sludge has certain viscosity and is easy to remain inside the scraper 2, in order to improve the efficiency of sludge treatment, a U-shaped frame 3 is arranged inside the scraper 2, and the U-shaped frame 3 can slide up and down inside the scraper 2. A push plate 4 is hinged to the U-shaped frame 3, the end of the push plate 4 away from the U-shaped frame 3 is attached to the bottom of the scraper 2, a sliding groove 5 is formed in the inner wall of the scraper 2, and a sliding block 6 is slidably arranged in the sliding groove 5 and fixedly connected to the push plate 4.

[0035] Referring to Figure 4 As shown in FIG. 6, when the U-shaped frame 3 slides upward in the inside of the scraper 2, the bottom end of the push plate 4 moves toward the U-shaped frame 3, and the sliding block 6 moves synchronously in the sliding groove 5. At this time, the push plate 4 is in an inclined state, and the top end is inclined toward the U-shaped frame 3. At this time, the sludge can also enter the U-shaped frame 3 along the inclined surface of the push plate 4 to ensure that the pushing and scraping treatment can be performed. When the U-shaped frame 3 slides downward in the inside of the scraper 2, the bottom end of the push plate 4 moves away from the U-shaped frame 3, and the sliding block 6 moves synchronously in the sliding groove 5.

[0036] In addition, when the U-shaped frame 3 slides to the highest position, the angle between the U-shaped frame 3 and the position below the push plate 4 is still an obtuse angle, that is, the top end is inclined toward the U-shaped frame 3, so that the pushing and scraping treatment can be performed. After the U-shaped frame 3 slides upward in the inside of the scraper 2, the push plate 4 can prevent the sludge from entering the position below the U-shaped frame 3 in the inside of the scraper 2. The sliding groove 5 and the sliding block 6 are arranged in the embodiment to improve the stability of the sliding of the push plate 4, and limit the movement range of the end of the push plate 4 away from the U-shaped frame 3.

At this time, the push plate 4 is in an inclined state, and the top end is inclined toward the U-shaped frame 3. At this time, the sludge can also enter the U-shaped frame 3 along the inclined surface of the push plate 4 to ensure that the pushing and scraping treatment can be performed. When the U-shaped frame 3 slides downward in the inside of the scraper 2, the bottom end of the push plate 4 moves away from the U-shaped frame 3, and the sliding block 6 moves synchronously in the sliding groove 5. The push plate 4 returns to the horizontal state, and the pushing and scraping treatment can be performed.

[0038] Further, when the U-shaped frame 3 is controlled to slide up and down in the inside of the scraper 2, the elastic sheet 7 produces a shaking effect to accelerate the sludge to slide to the suction cover 8, thereby improving the efficiency of the sludge scraping and sucking treatment.

[0039] Further, when the U-shaped frame 3 is controlled to slide up and down in the inside of the scraper 2, the elastic sheet 7 produces a shaking effect to accelerate the sludge to slide to the suction cover 8, thereby improving the efficiency of the sludge scraping and sucking treatment.

[0043] The truss 1 is provided with an electric sliding rail, and the electric sliding rail is provided with an electric sliding seat. The bottom of the electric sliding seat is fixedly connected with a second electric push rod 26. The second electric push rod 26 is fixedly connected with a fixing frame 25 on the extension end. The fixing frame 25 is fixedly connected with a submersible sewage pump 24. The suction pipe 10 is communicated with the feeding end of the submersible sewage pump 24. The electric sliding seat slides on the electric sliding rail. The second electric push rod 26 drives the submersible sewage pump 24 to move synchronously through the fixing frame 25. The submersible sewage pump 24 drives the scraper 2 to move through the suction pipe 10, so that the bottom position of the sedimentation tank is covered and cleaned. Meanwhile, the second electric push rod 26 drives the scraper 2 to move up and down through the suction pipe 10.

[0048] In the embodiment, a reversible V-shaped scraper 31 is arranged at the bottom of each of the two hangers 30, and the V-shaped scraper 31 is composed of a front baffle 31a and a rear baffle 31b, and the cross section of the V-shaped scraper 31 is V-shaped, and the V-shaped scraper 31 can be stretched and cast along the preset width during manufacturing.

[0050] The two V-shaped scrapers 31 are symmetrically arranged relative to the truss 1 in the direction of movement, so that the front flaps 31a of the two V-shaped scrapers 31 converge the sludge towards the center during the movement of the truss 1, so as to converge the sludge below the sludge suction pipe for suction. Specifically, the included angle between the front flaps 31a of the left and right V-shaped scrapers 31 and the forward movement direction of the truss 1 is the same, the included angle between the rear flaps 31b of the left and right V-shaped scrapers 31 and the backward movement direction of the truss 1 is the same, the included angle between the front flaps 31a of the left and right V-shaped scrapers 31 is greater than 120°, the included angle between the rear flaps 31b of the left and right V-shaped scrapers 31 is greater than 120°, and the included angle between the front flaps 31a of the left and right V-shaped scrapers 31 is equal to the included angle between the rear flaps 31b of the left and right V-shaped scrapers 31.

The V-shaped scraper 31 can be kept in a horizontal expansion state or a vertical recovery state under the driving of the driving device. As an example, the driving device can use a traction rope 32 connected to the V-shaped scraper 31 or a driving motor arranged between the V-shaped scraper 31 and the hanger 30 to drive the V-shaped scraper 31 to rotate along the hinge shaft, so as to switch the V-shaped scraper 31 between the horizontal expansion state and the vertical recovery state on both sides of the hanger 30. When it is necessary to push and scrape the sludge to concentrate, the V-shaped scraper 31 is controlled to rotate to the horizontal expansion state. After the V-shaped scraper 31 is rotated to the horizontal expansion state, the two V-shaped scrapers 31 can push and scrape the sludge from both sides to the middle during the movement of the truss 1. When it is not necessary to push and scrape the sludge to the middle, for example, during suction, the V-shaped scraper 31 is switched to the vertical recovery state by driving. In the vertical recovery state, the length direction of the V-shaped scraper 31 is arranged upwards along the vertical direction, so as to facilitate the rapid movement of the sludge suction pipe 10 and other devices on the truss 1 for suction.
