Description

Technical Field

[0001] This utility model relates to the field of sludge thickening technology, and in particular to a high-efficiency sludge thickening device. Background Technology

[0002] In the process of wastewater treatment, a large amount of sludge with high water content is often generated. In order to carry out further dewatering treatment of the sludge and reduce the sludge dewatering efficiency, it is necessary to concentrate the newly generated sludge with high water content.

[0003] Existing sludge thickening methods mostly rely on thickening tanks. Water is introduced into one end of the thickening tank, and after the other end is left to stand for a period of time, it will separate into layers. Then, the sludge and the water on top of the sludge are discharged through pipes. This operation requires a lot of time, which leads to relatively low equipment efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly efficient sludge thickening device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency sludge thickening device includes a tank. The top of the tank is detachably connected to a top cover by bolts. A fixed base is fixedly connected to the top of the top cover. A motor is fixedly connected inside the fixed base. A gear is movably connected to the bottom of the top cover. A gear ring is movably connected to the bottom of the top cover, and the gear meshes with the gear ring. A circular ring is fixedly connected to the bottom of the gear ring. A filter bucket is fixedly connected to the bottom of the circular ring. A detachable bottom cover is provided at the bottom of the filter bucket. A support frame is fixedly connected to the inner wall of the bottom of the tank.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0024] Reference Figures 1-4 A high-efficiency sludge thickening device includes a tank body 3. The top of the tank body 3 is detachably connected to a top cover 4 by bolts. A viewing window is provided on the top cover 4. A fixing seat 6 is fixed to the top of the top cover 4 by bolts. A motor is fixed inside the fixing seat 6 by bolts. A gear 15 is rotatably connected to the bottom of the top cover 4. A gear ring 13 is rotatably connected to the bottom of the top cover 4. The gear ring 13 is an external gear rotary bearing structure, and the gear 15 meshes with the gear ring 13. A circular ring 12 is welded to the bottom of the gear ring 13. A filter bucket 9 is fixed to the bottom of the circular ring 12 by bolts. A detachable bottom cover is provided at the bottom of the filter bucket 9. When the motor rotates, the gear 15 drives the gear ring 13 to rotate, thereby causing the circular ring 12 to drive the filter bucket 9 to rotate. Under the action of centrifugal force, the water in the sludge is thrown out, which facilitates rapid separation.

[0025] A support frame 11 is fixed to the bottom inner wall of the tank 3 by bolts. A turntable 10 is rotatably connected to the top of the support frame 11, and the turntable 10 is in contact with the bottom of the filter barrel 9. The turntable 10 can provide auxiliary support for the filter barrel 9.

[0026] In this utility model, it should be noted that the top of the tank body 3 is provided with an installation groove 16, and the bottom of the top cover 4 is bonded with a sealing ring 14, and the sealing ring 14 is located inside the installation groove 16. Through the cooperation of the sealing ring 14 and the installation groove 16, the connection between the tank body 3 and the top cover 4 is made tighter.

[0027] Both sides of the ring 12 are fixed with scraper 17 by bolts, and the scraper 17 is in contact with the inner wall of the tank 3. The ring 12 rotates to make the scraper 17 rotate to clean the inner wall of the tank 3, so as to prevent sludge and water from accumulating on the inner wall of the tank 3.

[0028] An observation port is provided on one side of the tank body 3, and a viewing window 2 is installed inside the observation port to facilitate the staff to understand the working conditions inside the tank body 3;

[0029] The tank body 3 has a connection port at the bottom, through which a separation pipe 8 is fixed. The top cover 4 has a water inlet in the middle, through which a water inlet pipe 5 is fixed. The bottom end of the separation pipe 8 is fixed with a filter screen 18 by bolts. The wastewater that is thrown out and cleaned is filtered and discharged through the filter screen 18. Both sides of the top cover 4 are fixed with hanging ears 7 by bolts. The bottom outer wall of the tank body 3 is fixed with multiple support columns 1 by bolts, and the multiple support columns 1 are symmetrically distributed.

[0030] The working principle of this utility model is as follows: When sludge needs to be treated, the untreated sludge water slowly enters the filter bucket 9 inside the tank 3 through the inlet pipe 5. The motor is started, and the rotation of the motor causes the gear 15 to drive the gear ring 13 to rotate, thereby causing the ring 12 to drive the filter bucket 9 to rotate. Under the action of centrifugal force, the water in the sludge is thrown out, and the sludge remains in the filter bucket 9. At the same time, the rotation of the ring 12 causes the scraper 17 to rotate to clean the inner wall of the tank 3, preventing the sludge water from accumulating on the inner wall of the tank 3. Then, a small amount of sludge thrown out mixed with the cleaned wastewater is filtered and discharged through the filter screen 18. The separation pipe 8 is disassembled periodically, the filter screen 18 is checked, and the sludge is discharged. The sludge can be observed through the viewing window on the top cover 4. When the filter bucket 9 is full, the top cover 4 is removed, and the bottom cover of the filter bucket 9 is opened to remove the sludge.
