Sewage treatment preorder solid filtration device

Abstract

The invention provides a sewage treatment preorder solid filtration device, and discloses a filtration device for isolating solid waste in sewage through a water baffle and conveying and squeezing thewaste into a solid concentrating box through rotation of a spiral conveying shaft to be stored. The sewage treatment preorder solid filtration device is characterized in that a discharging groove isformed in one end of the solid concentrating box, the discharging groove extends downwards to the bottom of the solid concentrating box, a sealing plate is arranged at one end of the solid concentrating box and corresponds to the discharging groove, the bottom of the sealing plate and the solid concentrating box are mutually hinged, plug pins are arranged on the two sides of the top of the sealingplate correspondingly, two plug pin fixing holes are formed in one end of the solid concentrating box and correspond to the plug pins on the two sides of the top of the sealing plate correspondingly,an inclined plate is arranged at the bottom of the solid concentrating box, the height of the inclined plate is gradually increased from one end of the solid concentrating box to the other end of thesolid concentrating box, the top of the solid concentrating box is of an open structure, a material guiding groove is formed in one side of the solid concentrating box and is close to the top of thesolid concentrating box, one end of an inclined pipe is arranged on one side of the solid concentrating box, and the inclined pipe correspondingly communicates with the material guiding groove.

Problems solved by technology

[0002] With the rapid development of cities in the 21st century, people's quality of life has improved, and the population has gradually increased. The resulting urban domestic sewage has increased significantly, and more and more attention has been paid to the treatment of domestic sewage. Domestic sewage contains a large amount of solid waste. These solid wastes need to be separated from sewage before centralized treatment, so that these solid wastes will not block the pipeline during subsequent treatment. The existing solid waste separation methods use manpower or simple claws to clean up, and the cleaning effect is poor and not thorough enough. When the garbage is transported with the pump body, it is easy to block the pipeline

[0004] The notification number CN105080212A discloses a sewage treatment tank, including a first filter tank and a second filter tank connected to the discharge pipe of the first filter tank, the first filter tank is a multi-stage solid filter tank, and the second filter tank is for removing Sewage treatment pool for floating objects, the upper part of the first filter tank is provided with a sewage inlet pipe, the lower part of the first filter tank is equipped with a discharge pipe, and a filter device is installed in the first filter tank, the filter device includes a stepped filter plate, and the upper stepped filter plate There is a square filter plate in the upper movable connection, and the stepped filter plate is composed of stepped plates on the left and right sides connected in a V shape; the sewage treatment tank for removing floating matter includes a sedimentation tank, and the sedimentation tank is connected with a floating matter cleaning tank, and the settling tank is set There is a sewage inlet pipe, and the sewage inlet pipe of the sedimentation tank is the discharge pipe of the first filter tank, and the lower part of the sewage inlet pipe of the sedimentation tank is provided with a water outlet pipe with a filter; the floating object cleaning tank is provided with a floating object discharge pipe, and the floating object The diameter of the discharge pipe is larger than the diameter of the water outlet pipe. After the first filter tank filters and separates the solids, the solid waste settles on its stepped filter plate. The solid waste is easy to accumulate and block the filter plate. At the same time, it is extremely difficult for personnel to clean the filter plate. convenient
