Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and particularly relates to an efficient and environment-friendly sewage recycling treatment device. Background Art

[0002] The sewage recycling treatment process is a complex and delicate system, which mainly includes three stages: physical treatment, biological treatment and chemical treatment. Among them, the physical treatment stage removes solid impurities and large particle suspensions in the water, using sewage ponds, grids and sedimentation tanks. After the sewage passes through the sewage pond, it first passes through the grid machine, which can intercept larger suspended solids and floating objects, such as plastic bags, tree branches, etc., to prevent these substances from blocking subsequent treatment equipment.

[0003] After retrieval, a grid with a cleaning function disclosed in the prior art with the publication number CN220803507U drives the installation shaft and the brush to rotate under the action of gear meshing connection, so that the brush further brushes off the impurities on the grid conveyor belt. In actual application, when the brush cleans the teeth on the conveyor belt for a long time, impurities will remain between the bristles of the brush. After long-term use, the brush will be wrapped by impurities, resulting in unclean cleaning of the grid, and the staff needs to regularly deal with the impurities on the brush.

[0004] Furthermore, after retrieval, a new type of grid machine for sewage treatment disclosed in the prior art with the publication number CN220779315U rotates the second pulley through belt transmission, opens the water pump to pump water through the water suction head, and sprays water from a pair of nozzles to wash the grid plate and the brush roller. The brush roller rotates to clean the grid plate. In actual application, if the water pressure of the nozzle is too high, the impurities on the grid plate and the brush roller will not fall vertically, resulting in the impurities being washed to one side of the waste hopper and entering the water body. When the water pressure of the nozzle is too low, although the impurities will not be affected by the water pressure and freely fall into the waste hopper, the impurities on the brush roller cannot be washed clean.

[0005] Therefore, the present application provides a solution for an efficient and environment-friendly sewage treatment recycling device, which can clean the residual impurities on the grid machine brush through a cleaning device, and at the same time prevent the impurities from being affected by external forces when cleaning the brush roller and washing the impurities outside the discharge bin.

At the same time, a grid cleaning mechanism is provided to assist in cleaning the impurities on the toothed rake, preventing the residual impurities on the toothed rake from falling into the water body behind the grid bars along with the movement of the traction chain, which affects the water quality after grid bar filtration.

[0040] An efficient and environmentally friendly sewage recycling treatment device has the following working process:

[0041] During use, first, the sewage sump 1 discharges sewage into the sedimentation tank. At this time, the sewage is filtered by the rotary grid decontamination machine 2. The driving speed-changing mechanism 211 drives the main shaft 213 to rotate through the conveyor belt. The main shaft 213 drives the traction chain 216 to rotate. The traction chain 216 drives the rake 215 to move in cooperation around the grid bars 217. The residues filtered out by the grid bars 217 are moved upward by the rake 215, then through the slag tray, and then through the cooperation of the rake 215 and the traction chain 216 to the lower end of the main shaft 213. The impurities fall from the rake 215 into the discharge bin 232 by gravity, and then the auger blade 233 is driven by the driving motor 231 to discharge the impurities into the hopper truck 235.

[0042] At the same time, when the rake 215 discharges impurities into the discharge bin 232, impurities will adhere to the rake 215. When the rake 215 rotates to the lower end in a cycle, the impurities will be washed into the sedimentation tank 3 by the water flow, affecting the water quality. Therefore, it is necessary to remove the impurities through the grid cleaning mechanism 22 before the rake 215 rotates to the lower end of the water body.

[0043] First, the grid cleaning mechanism 22 is started by the rotating motor 2236. The driving rotating shaft 2234 drives the brush roller 2232 to rotate. The brush roller 2232 cleans the impurities on the surface of the rake 215 through the bristles, preventing the impurities remaining downward on the rake 215 from being brought into the water filtered by the lower grid bars 217 and affecting the filtration of the grid bars 217.

[0044] At the same time, during the sewage treatment and after long-term use, impurities will remain on the surface of the brush roller 2232, wrapping the brush roller 2232 and affecting the filtration effect of the brush roller 2232. Therefore, it is necessary to clean the brush roller 2232. The through-type screw stepper motor 2231 is started. The through-type screw stepper motor 2231 drives the screw to rotate and extend in the through-type screw stepper motor 2231. The screw cooperates with the bearing in the bearing seat 22333 to move along the axis of the rotating shaft 2234, driving the brush roller 2232 to move horizontally. There are two brush rollers 2232 on the rotating shaft 2234. The screw drives the clamping component 2233 to move back and forth through the bearing seat 22333, so that one side of the brush roller 2232 enters the sealing cover 222. After the other side of the brush roller 2232 enters the sealing cover 222, it contacts the push-button 2235, starting the spray head on the sealing cover 222 corresponding to the push-button 2235 to spray water. The high pressure washes the brush roller 2232 in the sealing cover 222 with water. The impurities are washed onto the sealing cover 222 by the water flow and slide down the sealing cover 222 into the discharge bin 232. The water is filtered through the water filtering holes on the discharge bin 232. The two brush rollers 2232 on the rotating shaft 2234 are cleaned alternately back and forth under the drive of the screw in the same way. The function of the sealing cover 222 is to prevent the impurities from being washed outside the discharge bin 232 when the high-pressure water flow flushes the brush roller 2232, affecting the water quality after the grid bars 217 are filtered.

[0045] In summary, electronic or electrical components including but not limited to through-type lead screw stepper motors, push buttons, rotary motors, shunts, water pumps, and drive motors are components in the prior art, obtained through private customization or purchase. The electrical connections between the components are all conventional circuit connections or electrical connections in the prior art, and are not within the protection scope of the present utility model.
