Problems solved by technology

[0002] The sludge scraper for sewage treatment is mostly used in the sedimentation tank. A large amount of sludge settles at the bottom of the sedimentation tank. It needs to be loosened by the sludge scraper, pushed and then discharged with the sewage pipe in the middle of the sedimentation tank. The core component of the sludge scraper is the rotating part. The rotating part The lower part of the mud scraper is equipped with a scraper. During the rotation of the rotating parts, the scraper does work on the sludge in the lower part of the sedimentation tank. However, this type of mud scraper has a large volume and a large rotational resistance, which not only has high cost, but also greatly reduces the service life of the motor and the overall structure. Intensity; and it will cause the sedimented sludge to become muddy again

Embodiment 1

[0030] see Figure 1-4 , a transmission mud scraper for sewage treatment, including a power rotating pile 1, a screw auger 2 and a negative pressure cover 3, the power rotating pile 1 is installed in the middle of the bottom of the sedimentation tank, and the screw auger 2 plays a role in loosening and settling The role of the sludge at the bottom of the pool, the negative pressure cover 3 plays the role of negative pressure to attract the loose sludge and water mixture, and then the sewage mixture is discharged through the external plunger pump, the power rotating pile 1 is in a passive rotation state, and it is connected to the screw 2 and the negative pressure cover 3, the screw auger 2 and the negative pressure cover 3 rotate in the sedimentation tank, which can realize the function of comprehensive mud discharge. Specifically, the outer wall of the power rotating pile 1 is fixed with a horizontally distributed suspension rod 4, and the negative pressure The pressure cover...

Embodiment 2

[0032] see Figure 5, in embodiment 1, although the two wing plates 7 before and after the negative pressure cover 3 are extruded and contacted with the sludge surface to prevent the sludge from getting muddy, some sludge will be exposed and spread upwards. The difference between this embodiment and Embodiment 1 is that the power rotary pile 1 is provided with a filtering device 8, and the filtering device 8 is used in conjunction with the rotating drive shaft 5, and the auger blade 22 on the auger 2 can be used to remove sludge The direction of rotation to push toward the power rotating pile 1, specifically, the filter device 8 includes a water filter cover 81 and a rotating sleeve 82, the water filter cover 81 is fixedly set on the outside of the power rotating pile 1 and has an opening at the bottom, and the water filter cover 81 The top of the top has a water hole and can be installed with sludge filter cotton. The rotating sleeve 82 is set outside the power rotating pile ...

Abstract

The invention discloses a transmission mud scraper for sewage treatment. The transmission mud scraper comprises a power rotating pile, a spiral auger and a negative pressure cover, and a horizontallydistributed suspension rod is fixedly arranged on the outer surface wall of the power rotating pile. According to the invention, the power rotating pile is arranged at the bottom of the sedimentationtank, the outer periphery of the power rotating pile is connected with the negative pressure cover and the spiral auger positioned at the lower part of the negative pressure cover, a roller is mountedat the free end of an auger shaft of the spiral auger, and an abdicating notch through which auger blades on the spiral auger can penetrate conveniently is formed in the lower part of the negative pressure cover; the negative pressure cover can move up and down relative to the spiral auger, wing plates are arranged in front of and behind the negative pressure cover in the moving direction and play a role in assisting the negative pressure cover in sliding on sludge, and therefore the spiral auger rotates, the idler wheel at the far end of the spiral auger can rotate to pass through, the powerrotating pile drives the negative pressure cover to rotate, and loads are small. The spiral augerrotates, the deposited sludge can be sucked and discharged through the negative pressure cover, and apollution discharge effect is achieved.
