Roller sand screening machine for building

Abstract

The invention discloses a drum sand screening machine for construction, which comprises a hopper, a turning arm, a motor I, a motor II, a motor III, a drum, a baffle I, a baffle II, a transmission device, Frame, transmission device frame, baffle IV, chain drive, gear III, gear IV, eccentric wheel; motor I is installed on the side below the hopper, and a turning arm is installed on the side of motor I, and motor I is installed on the bottom of the hopper On the outer wall, the motor I is connected with the turning arm to drive the turning arm to rotate in the hopper. The invention avoids the material blocking in the hopper, ensures the working efficiency of the drum sand screening machine, and prevents the materials moving with the drum from spilling outwards, reduces the manual workload in the later stage, and changes the drum The original motion trajectory realizes better separation of materials and increases the working efficiency of the drum sand screening machine.

Description

technical field [0001] The invention belongs to the technical field of construction engineering facilities, in particular to a drum sand screening machine for construction. Background technique [0002] The drum sand screening machine is a special screening equipment developed for power plants, coking plants, building materials, metallurgy, chemical industry, mining and other industries. The drum sand screening machine overcomes the screen stickiness of various vibrating screens when screening wet materials. Blocking problems improves the output value and reliability of the screening system. The trommel screen is composed of a drum, frame, funnel, motor and other parts. After the material enters the drum, it is screened as the drum rotates on the one hand. The stone flows forward along the slope of the drum, and is gradually screened out through screens of different meshes; the material enters the hopper and moves downward along the hopper. During this process, sometimes the...

[0002] The drum sand screening machine is a special screening equipment developed for power plants, coking plants, building materials, metallurgy, chemical industry, mining and other industries. The drum sand screening machine overcomes the screen stickiness of various vibrating screens when screening wet materials. Blocking problems improves the output value and reliability of the screening system. The trommel screen is composed of a drum, frame, funnel, motor and other parts. After the material enters the drum, it is screened as the drum rotates on the one hand. The stone flows forward along the slope of the drum, and is gradually screened out through screens of different meshes; the material enters the hopper and moves downward along the hopper. During this process, sometimes the material blocks the hopper, and the subsequent The work cannot be carried out, which seriously affects the working efficiency of the drum sand screening machine; because the material enters the drum and moves with the drum, and there is no barrier above the drum of the existing drum sand screen machine, the material will easily spill out However, manual cleaning is required in the later stage, which increases the workload of labor; the material rotates at a constant speed in the drum, although the material can be separated, but the residue coming out of the drum will also be mixed with a small amount of sand. Incomplete, resulting in unnecessary waste
