Description

Technical Field

[0001] This utility model relates to the field of loosening device technology, specifically a central drive sludge scraper bottom sludge collection hopper loosening device. Background Technology

[0002] The center-driven sludge scraper adopts a center-driven suspended type. Sewage flows into the guide tube from the inlet pipe under the working bridge and then diffuses evenly to the periphery in a radial pattern. The suspended sludge settles at the bottom of the pool after sedimentation. The drive device drives the central vertical shaft to rotate, which in turn drives the scraper arm and scraper plate to rotate, scraping the sludge from the pool periphery to the central sludge collection trough. Then, it is discharged from the pool by the static water pressure in the pool through the sludge discharge pipe. The scum on the water surface is scattered to the pool side by the rotating skimming device and then scraped into the scum discharge hopper by the scum scraper and discharged from the pool. The supernatant overflows into the effluent trough through the triangular effluent weir plate and is discharged.

[0003] However, the device has some shortcomings. When in use, it lacks support and is not stable when rotating in mud collection tanks of different sizes. At the same time, the device is not convenient for cleaning the inside of mud collection tanks of different widths. Utility Model Content

A spring is provided on the outer side of the support rod, and a support roller is provided on the bracket. The support roller is slidably connected to the mud collection trough. The spring acts on the bracket, causing the support roller to contact the mud collection trough, making the rotation of the main shaft and related structures within the mud collection trough more stable, and allowing rotation within mud collection troughs of varying widths.

[0007] Preferably, one end of the spring is fixedly connected to the support plate, and the other end of the spring is fixedly connected to the bracket. By setting the spring, the bracket is pressed away from the support plate.

By rotating the bidirectional screw and the top plate to perform threaded movement, the top plate compresses the compression spring, which in turn compresses the mounting plate, thereby changing the distance between the evacuation frame and the main shaft, allowing the device to clean sludge in sludge collection tanks of different widths.

[0010] Preferably, a retaining ring is fixedly connected to the outer side of the bidirectional screw, and the retaining ring contacts the support sleeve. By providing the retaining ring, the bidirectional screw is prevented from moving out of its proper place.

[0011] Preferably, one end of the compression spring is fixedly connected to the top plate, and the other end of the compression spring is fixedly connected to the mounting plate. By setting the compression spring, the mounting plate is elastically pressed against the top plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a spring to act on the bracket, thereby making the support roller and the mud collection trough contact, making the main shaft and related structures rotate more stably in the mud collection trough, and allowing them to rotate in mud collection troughs of different widths.

[0014] 2. This utility model uses the rotation of the bidirectional screw and the top plate to make a threaded movement, which causes the top plate to compress the compression spring, which in turn compresses the mounting plate, thereby changing the distance between the evacuation frame and the main shaft, so that the device can clean the sludge in the sludge collection tanks of different widths.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 A centrally driven sludge scraper bottom sludge collection bucket loosening device includes a sludge collection trough 1 and a main shaft 2. A support frame 3 is provided on the outside of the main shaft 2, and a support mechanism 4 is provided at the end of the support frame 3. A connecting sleeve 5 is connected to the outside of the main shaft 2 by screws. A sludge evacuation frame 6 is provided on the connecting sleeve 5, and an adjustment mechanism 7 is provided on the connecting sleeve 5. A sludge discharge pipe 8 is fixedly connected inside the sludge collection trough 1.

[0022] Please see Figures 1-2 The support mechanism 4 includes a support plate 41. The support plate 41 is fixedly connected to the end of the support frame 3. A support rod 42 is slidably connected inside the support plate 41. A bracket 43 is fixedly connected to the end of the support rod 42. A spring 44 is provided on the outside of the support rod 42. One end of the spring 44 is fixedly connected to the support plate 41, and the other end of the spring 44 is fixedly connected to the bracket 43. By setting the spring 44, the bracket 43 is pressed away from the support plate 41. A support roller 45 is provided on the bracket 43. The support roller 45 is slidably connected to the mud collection trough 1. A guide rod 46 is fixedly connected to the surface of the bracket 43. The guide rod 46 is slidably connected to the support plate 41. By setting the guide rod 46, the movement of the bracket 43 is guided. The spring 44 acts on the bracket 43, thereby making the support roller 45 contact the mud collection trough 1, so that the main shaft 2 and related structures rotate more stably in the mud collection trough 1, and can rotate in mud collection troughs 1 with different widths.

[0023] Please see Figure 1 , Figure 3 , Figure 4The adjusting mechanism 7 includes a slide rod 71. The slide rod 71 is fixedly connected to the surface of the connecting sleeve 5, and the slide rod 71 is slidably connected to the evacuation frame 6. A double-acting screw 72 is rotatably connected inside the main shaft 2. A support sleeve 73 is fixedly connected to the surface of the main shaft 2. A retaining ring 74 is fixedly connected to the outer side of the double-acting screw 72, and the retaining ring 74 contacts the support sleeve 73. By setting the retaining ring 74, the double-acting screw 72 is prevented from moving. A mounting plate 75 is fixedly connected to the upper end of the evacuation frame 6, and the mounting plate 75 is movably connected to the double-acting screw 72. A top plate 76 is threadedly connected to the outer side of the double-acting screw 72, and the top plate 76 is slidably connected to the evacuation frame 6. A compression spring 77 is provided on the outer side of the double-acting screw 72, and one end of the compression spring 77 is fixedly connected to the top plate 76. The other end of the spring 77 is fixedly connected to the mounting plate 75. By setting the compression spring 77, the mounting plate 75 is elastically pressed. By rotating the bidirectional screw 72 and the top plate 76 to make threaded movement, the top plate 76 compresses the compression spring 77, which in turn compresses the mounting plate 75. This causes the distance between the evacuation frame 6 and the main shaft 2 to change, thereby enabling the device to clean the sludge in the sludge collection tank 1 with different widths.

[0024] The specific implementation process of this utility model is as follows: During use, the width of the sludge collection trough 1 is automatically adjusted. The spring 44 acts elastically on the bracket 43, thereby causing the support roller 45 to contact the sludge collection trough 1. This makes the rotation of the main shaft 2 and related structures within the sludge collection trough 1 more stable, and allows rotation within sludge collection troughs 1 of different widths. Then, the bidirectional screw 72 is driven to rotate by a detachable driver. The bidirectional screw 72 rotates and makes a threaded movement with the top plate 76, thereby causing the top plate 76 to slide on the evacuation frame 6 and compress the compression spring 77. This causes the compression spring 77 to compress the mounting plate 75, and the mounting plate 75 drives the evacuation frame 6 to move, thereby changing the distance between the evacuation frame 6 and the main shaft 2. This allows the device to clean the sludge in sludge collection troughs 1 of different widths. Furthermore, the elastic action of the compression spring 77 prevents the evacuation frame 6 from jamming with the side wall of the sludge collection trough 1, which would affect the rotation of the device.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
