Description

Technical Field

[0001] This utility model relates to the field of semi-bridge scraper and suction sludge machine, specifically a semi-bridge peripheral drive scraper and suction sludge machine. Background Technology

[0002] The semi-bridge peripheral drive sludge scraper is a wastewater treatment device used in circular sedimentation tanks in water supply and drainage projects. It is used to scrape sludge from the bottom of the tank and remove scum from the surface. It mainly consists of a working bridge, transmission mechanism, scum funnel, sludge collection trough, sludge suction pipe, siphon pipe, vacuum system, central power collection device, central support, effluent weir plate and scum baffle, and electrical control box. Its principle is that wastewater flows out radially from the inlet pipe in the center of the tank through the guide tube, and the suspended sludge settles at the bottom of the tank. The supernatant is discharged from the tank through the overflow weir plate and effluent trough. The drive mechanism rotates the working bridge around the center of the tank. The sludge settled at the bottom is collected by the sludge collection plate to each sludge suction port. Under the action of the liquid level difference, the sludge is discharged from the tank through the sludge suction port, sludge collection trough, siphon pipe, central sludge tank, and sludge discharge pipe. The current semi-bridge peripheral drive scraper and suction machine is inconvenient to adjust the position of the scraper, so a semi-bridge peripheral drive scraper and suction machine is needed.

[0003] Existing patent document CN204709888U discloses a high-efficiency sludge scraper, which includes a pool body. An inlet pipe with a solenoid valve is located on one side of the upper part of the pool body. A cylindrical four-groove structure is located at the center of the bottom of the pool body. The bottom surface of the pool body is inclined. A track is provided on the upper surface of the pool body. A bridge frame is provided on the upper part of the pool body. A drive motor is fixedly connected to the bridge frame. The drive motor is connected to a drive shaft, and rollers are connected to both ends of the drive shaft. A connecting bracket A is provided on the inner circumference of the lower surface of the bridge frame, and a connecting bracket B is provided on the outer circumference of the lower surface of the bridge frame. Fixed rods A and B are respectively connected to the lower ends of connecting brackets A and B. The sides of scraper blades are connected to both ends of fixed rods A and B. A connecting frame is connected to the connecting bracket A, and a sludge pump is fixedly connected to the lower part of the connecting frame. The sludge pump, connected to the sludge discharge pipe, has the advantages of simple structure, wide applicability, stable operation, thorough sludge scraping, high sludge concentration, and high continuity. However, the CN204709888U technology is inconvenient to adjust the height of the scraper according to actual usage needs during operation. It usually adopts fixed or extremely inconvenient connection methods such as welding and bolt fastening. This makes it almost impossible to flexibly change the height of the scraper during on-site operation after installation. In some cases, the sludge accumulation is thick, possibly reaching tens of centimeters or even more. At this time, the existing scraper and suction machine scraper cannot be lowered to a suitable position due to its fixed height, making it difficult to fully and effectively scrape off the large amount of accumulated sludge. This greatly reduces the sludge scraping efficiency, leaving a large amount of sludge at the bottom of the pool, affecting the subsequent treatment process. Therefore, there is an urgent need for a semi-bridge peripheral drive scraper and suction machine. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a semi-bridge peripheral drive scraper and suction machine to solve the problem that the height of the scraper is not easily adjustable according to actual usage requirements in existing semi-bridge peripheral drive scraper and suction machines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a semi-bridge type peripheral drive scraper and suction machine, including a central support column, a semi-bridge type scraper and suction machine working bridge installed on the top of the central support column, and an adjustment mechanism installed on the outer wall of the semi-bridge type scraper and suction machine working bridge.

[0006] The adjustment mechanism includes a drive motor fixedly installed on the top of the working bridge of the half-bridge sludge scraper. The output shaft of the drive motor is fixedly connected to a threaded rod via a coupling. A movable sleeve is movably connected to the outer wall of the threaded rod. A threaded groove is opened inside the movable sleeve. A base frame is fixedly connected to the bottom of the movable sleeve. A guide rod is fixedly connected to the top of the base frame. A slider is fixedly connected to the outer wall of the guide rod. A limit sleeve is connected to the outer wall of the guide rod. A sliding groove is opened inside the limit sleeve.

[0007] Preferably, the limiting sleeve is fixedly installed at the bottom of the working bridge of the half-bridge sludge scraper, the limiting sleeve is a slotted design, and the limiting sleeve and the guide rod form a sliding structure.

[0008] Preferably, the slider is symmetrically arranged about the central axis of the guide rod, and the slider forms a sliding structure with the limiting sleeve through the sliding groove.

[0009] Preferably, the threaded rod and the working bridge of the half-bridge sludge scraper form a rotating structure, and the threaded rod is threadedly connected to the movable sleeve through a threaded groove.

[0010] Preferably, a first semi-threaded column is fixedly connected to the outer wall of the base frame, an clearance groove is provided inside the base frame, an insert plate is installed inside the base frame, a second semi-threaded column is fixedly connected to the outer wall of the insert plate, a limit nut is movably connected to the outer wall of the second semi-threaded column, a support rod is fixedly connected to the bottom of the insert plate, and a scraper is fixedly connected to one end of the support rod.

[0011] Preferably, the base frame is engaged with the insert plate via a clearance groove, and the support rods are evenly distributed at the bottom of the insert plate.

[0012] Preferably, the first semi-threaded post is threadedly connected to the limiting nut, and the second semi-threaded post is threadedly connected to the limiting nut, and the first semi-threaded post and the second semi-threaded post are adapted to each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of the adjustment mechanism and the scraper, can make the threaded rod rotate by starting the drive motor. Since the threaded rod is threadedly connected to the movable sleeve through the threaded groove, the movable sleeve can be raised and lowered along the threaded rod, so that the guide rod slides along the limit sleeve, driving the slider to slide stably along the slide groove. With the sliding cooperation of the guide rod and the limit sleeve, the movable sleeve can only be raised and lowered along the threaded rod, and will not rotate with the rotation of the threaded rod, thereby driving the scraper at the bottom to be raised and lowered for adjustment. This makes it easy to adjust the height of the scraper according to the actual use needs, so that the semi-bridge peripheral drive scraper can be used for scraping sludge of different thicknesses in sewage tanks in different seasons.

[0015] 2. This utility model, through the setting of a first semi-threaded post, a clearance groove, an insert plate, a second semi-threaded post, a limiting nut, a support rod, and a scraper, allows the limiting nut to be moved out and released from its limiting position on the first and second semi-threaded posts by rotating it, since the limiting nut is threadedly connected to the first and second semi-threaded posts respectively. Similarly, by disassembling the other two limiting nuts and pulling down the scraper, the insert plate fixedly connected to the top of the support rod can be moved out of the clearance groove, thus separating the first and second semi-threaded posts. This allows for the disassembly and replacement of worn scraper blades, and the insertion of new scraper blades, thereby facilitating the replacement of worn scraper blades and improving the convenience of disassembly and assembly.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] The embodiments of this utility model will be described below based on its overall structure.

[0024] Please see Figure 1-5 A semi-bridge type peripheral drive scraper / suction sludge machine includes a central support column 1. A working bridge 2 is mounted on the top of the central support column 1. An adjustment mechanism 3 is installed on the outer wall of the working bridge 2. The adjustment mechanism 3 includes a drive motor 31 fixedly mounted on the top of the working bridge 2. The output shaft of the drive motor 31 is fixedly connected to a threaded rod 32 via a coupling. A movable sleeve 33 is movably connected to the outer wall of the threaded rod 32. A threaded groove 34 is formed inside the movable sleeve 33. A base frame 35 is fixedly connected to the bottom of the movable sleeve 33. A guide rod 36 is fixedly connected to the top of the base frame 35. A slider 37 is fixedly connected to the outer wall of the guide rod 36. The outer wall is connected to a limiting sleeve rod 38, and the limiting sleeve rod 38 has a sliding groove 39 inside. The limiting sleeve rod 38 is fixedly installed at the bottom of the working bridge 2 of the half-bridge sludge scraper. The limiting sleeve rod 38 has a slotted design. The limiting sleeve rod 38 and the guide rod 36 form a sliding structure. The slider 37 is symmetrically arranged about the central axis of the guide rod 36. The slider 37 forms a sliding structure with the limiting sleeve rod 38 through the sliding groove 39. The threaded rod 32 forms a rotating structure with the working bridge 2 of the half-bridge sludge scraper. The threaded rod 32 is threadedly connected to the movable sleeve 33 through the threaded groove 34, which can facilitate the adjustment of the height of the scraper 10 according to actual use needs, thus improving the applicability of the half-bridge peripheral drive sludge scraper.

[0025] Please see Figure 1-5 A semi-bridge type peripheral drive scraper and suction machine is disclosed. A first semi-threaded column 4 is fixedly connected to the outer wall of the base frame 35. An avoidance groove 5 is opened inside the base frame 35. An insert plate 6 is installed inside the base frame 35. A second semi-threaded column 7 is fixedly connected to the outer wall of the insert plate 6. A limit nut 8 is movably connected to the outer wall of the second semi-threaded column 7. A support rod 9 is fixedly connected to the bottom of the insert plate 6. A scraper 10 is fixedly connected to one end of the support rod 9. The base frame 35 is engaged with the insert plate 6 through the avoidance groove 5. The support rods 9 are evenly distributed at the bottom of the insert plate 6. The first semi-threaded column 4 is threadedly connected to the limit nut 8. The second semi-threaded column 7 is threadedly connected to the limit nut 8. The first semi-threaded column 4 and the second semi-threaded column 7 are adapted to each other, which can facilitate the disassembly and replacement of the worn scraper 10.

[0026] Working Principle: During operation, starting the drive motor 31 rotates the threaded rod 32. Since the threaded rod 32 is threadedly connected to the movable sleeve 33 via the threaded groove 34, the movable sleeve 33 can rise and fall along the threaded rod 32. This causes the guide rod 36 to slide along the limiting sleeve 38, driving the slider 37 to slide stably along the sliding groove 39. With the sliding cooperation of the guide rod 36 and the limiting sleeve 38, the movable sleeve 33 will only rise and fall along the threaded rod 32, and will not rotate with the threaded rod 32. This, in turn, drives the scraper plate 10 at the bottom to rise and fall. By activating the conveying device at the edge of the working bridge 2 of the half-bridge scraper, the central support 1 at the bottom of the working bridge 2 of the half-bridge scraper can rotate along the sewage tank, allowing the scraper plate 10 to move. The mud scraper 10 scrapes and cleans the sludge at the bottom of the sewage tank. By rotating the limiting nut 8, which is threaded to the first half-threaded post 4 and the second half-threaded post 7 respectively, the limiting nut 8 can be moved out and the limiting of the first half-threaded post 4 and the second half-threaded post 7 can be released. Similarly, the other two limiting nuts 8 can be disassembled. Pulling the mud scraper 10 downwards can move the insert plate 6 fixedly connected to the top of the support rod 9 out of the relief groove 5, so that the first half-threaded post 4 and the second half-threaded post 7 can be separated. The worn mud scraper 10 can be disassembled and replaced, and a new mud scraper 10 can be installed. This completes the use of the device.
