Description

Technical Field

[0001] This utility model relates to the technical field of dewatering equipment, specifically to a complete screen structure for a slat dewatering machine. Background Technology

[0002] Slat dewatering machines (usually referring to slat screw extrusion dewatering machines) are solid-liquid separation equipment for materials with high impurities. They are widely used in environmental protection, mining, chemical and other industries. Their screen structure directly determines the dewatering efficiency, throughput and equipment operation and maintenance costs.

[0003] In related technologies, the slat dewatering machine mainly includes a spiral shaft set in a spiral feeding channel and spiral blades set on the surface of the spiral shaft. Through the filter holes on the spiral feeding channel wall and the extrusion of the spiral blades, the material in the spiral feeding channel is separated into solid and liquid. The compressed solid waste moves to the discharge end of the spiral feeding channel and forms an extrusion band through the baffle set at the discharge end, thereby achieving solid-liquid separation. The input end of the spiral shaft is equipped with a coupling, reducer, motor and other drive and shaft speed regulating components.

[0004] Most existing dewatering machine screens are fixed to the surface of the screw shaft (usually fixed to the upper surface of the screw feeding channel and connected to the screw feeding channel). The mesh on the wall of the screw feeding channel is the inner screen, and the outer arc-shaped strip is the outer screen. When the outer screen needs to be disassembled and cleaned, the machine needs to be stopped, which makes it inconvenient to maintain the parts. To solve the above problems, a strip-type dewatering machine screen structure is proposed to solve the above problems. Utility Model Content

[0005] In view of this, the present invention provides a complete screen structure for a slatted dewatering machine. The present invention opens the positioning assembly by separating the irregular positioning plate and the receiving positioning plate, removing the bolts of the upper positioning plate and the lower positioning plate, and then separating the upper concave block and the lower concave block. The bolts on the connecting plate can be removed to remove the tile plate. After disassembly, it can be cleaned with water and cleaning tools. After cleaning, it can be reinstalled without stopping the machine, avoiding the need to replace the outer screen, thereby improving the production efficiency of the equipment.

[0006] To solve the above-mentioned technical problems, this utility model provides a complete screen structure for a slatted dewatering machine, including a motor at the drive end of the spiral dewatering machine, a spiral shaft at the output end of the motor, spiral blades on the surface of the spiral shaft, the size of the spiral blades decreasing from front to back, a bearing seat at the rear end of the spiral dewatering machine, a filter channel on the surface of the spiral blades, the filter channel being a hollow conical shape, multiple detachable screen assemblies on the surface of the filter channel, the size of the screen assemblies decreasing from front to back, a support assembly between every two screen assemblies, and a positioning assembly on the left and right sides of each screen assembly.

[0007] Each screen assembly includes a pair of plates for assembling into a conical cylinder. The plates are used for solid-liquid separation and to prevent the dehydrated material from being squeezed out. Each plate has several through holes on its surface, which are staggered with the filter holes in the filter channel. Each pair of plates is symmetrically designed. Each plate has a connecting plate on its left and right sides. The connecting plate is used to connect the two symmetrical plates into a single conical cylinder.

The upper recessed block is also used to connect both the upper and lower tiles to the positioning assembly.

[0009] The positioning assembly includes a shaped positioning plate located on the upper part of the concave block. The shaped positioning plate is used to connect and fix the screen assembly to the storage tank, thereby supporting the positioning assembly. The end of the shaped positioning plate near the spiral shaft is arched, and the arched end of the shaped positioning plate is placed in the recess of the upper concave block. A receiving positioning plate is provided at the lower part of the lower concave block. The receiving positioning plate, together with the shaped positioning plate, is used to connect and fix the upper and lower concave blocks. The arched end of the receiving positioning plate and the shaped positioning plate are connected and fixed by bolts.

[0010] A slot is provided at the center of the lower part of the irregular positioning plate.
