Technical Field

[0001] This utility model belongs to the technical field of sludge conveying equipment, specifically relating to a sludge screw conveyor for removing impurities. Background Technology

[0002] Screw conveyors are commonly used industrial conveying equipment, capable of transporting granular solids and fluids with low viscosity. They are characterized by quantitative and continuous operation, as well as excellent fluid sealing. In the sludge drying and incineration process, sludge with an 85% moisture content, after being transported by tank truck to the designated sludge receiving pool at the site, needs to be conveyed by a screw conveyor to a sludge screw pump, and then pumped to a sludge storage tank to complete the sludge collection and storage process.

[0003] In existing related technologies, due to the diverse sources of sludge and human factors, the impurities in the sludge are uncontrollable, which may result in the presence of impurities such as packaging bags and leaves in the sludge. During the screw conveying process, the screw is easily jammed or blocked, making it impossible to effectively seal, move, and clean the impurities adhering to the screw blades. Therefore, there is an urgent need to design a sludge screw conveyor for removing impurities to deal with these problems. Utility Model Content

[0030] In this embodiment: the conveying mechanism 2 includes a frame 201 fixedly mounted above the base 1. A square box 202 is horizontally mounted above the frame 201. A spiral conveying assembly is horizontally arranged inside the square box 202. A secondary gear 2051 is mounted at one end of the spiral conveying assembly. A drive motor 204 is arranged on one side of the secondary gear 2051. A main gear 205 is arranged at the power end of the drive motor 204 and meshes with the secondary gear 2051. A discharge assembly is arranged below the square box 202. A telescopic baffle 209 is arranged longitudinally on the discharge assembly. An electric telescopic rod 2091 is arranged behind the telescopic baffle 209. A corrugated plate limiting frame 2021 is horizontally mounted inside the square box 202. A telescopic corrugated plate 211 is arranged inside the corrugated plate limiting frame 2021 and installed inside the square box 202. A connecting frame 210 is arranged above the telescopic corrugated plate 211. The screw conveyor assembly includes a rotating shaft 203 arranged laterally within the square box 202, with screw blades 2031 mounted on its outer surface. The discharge assembly includes a guide pipe 207 located below the square box 202, with a discharge pipe 208 at its lower end. A feed pipe 206 is located on one side of the square box 202.

[0031] In this embodiment: the mobile cleaning mechanism 3 includes a back plate 301 fixedly mounted on the rear side of the base 1. A horizontal moving component 302 is horizontally mounted on the back plate 301. A cleaning water tank 303 is mounted above the back plate 301. A connecting pipe 304 is mounted on the cleaning water tank 303. A lifting hydraulic cylinder 305 is vertically mounted on the horizontal moving component 302. A connecting platform 309 is mounted at the telescopic end of the lifting hydraulic cylinder 305. A pressure pump 307 is mounted above the connecting platform 309. A corrugated moving pipe 306 is provided between the connecting pipe 304 and the pressure pump 307. Cleaning nozzles 308 are equidistantly arranged below the connecting platform 309. The connecting platform 309 and the cleaning nozzles 308 are connected by connecting threads. A water pump is installed inside the cleaning water tank 303.
