Simple drum type screen

Abstract

The invention relates to a material screening tool, in particular to a simple drum type screen. The simple drum type screen comprises a screen drum, a screen drum center shaft, a material receiving box and a rotating device, wherein the screen drum is rotationally installed on the material receiving box through the screen drum center shaft, a material inlet is formed in any end of the screen drum, any end of the screen drum center shaft is connected with the rotating device, the rotating device drives the screen drum to rotate by using the screen drum center shaft as the center, the rotating device comprises a connecting rod and a handle, one end of the connecting rod is connected with the screen drum center shaft, the handle is arranged at the other end of the connecting rod, screen drum sealing covers are arranged at the two ends of the screen drum respectively, and the screen drum center shaft penetrates through the centers of the screen drum sealing covers and extend towards the two sides to the two opposite side walls of the material receiving box. The simple drum type screen is simple in structure and low in production cost, the amount of materials screened every time is large, labor is saved, the utilization efficiency of screen cloth is improved, and heavy work of screening operation is reduced.

Description

technical field [0001] The invention relates to a material screening tool, in particular to a simple drum type sieve. Background technique [0002] In daily life, we often use sieves to separate coarse and fine particles of materials. At present, the sieves we commonly use are mainly reciprocating sieves. By alternately exerting force on both sides of the sieve, the particles are separated by gravity and material inertia. Conventional reciprocating sieves are as follows: Problems: (1) The amount of materials input each time is small. Since there is only one contact surface between the screen and the material, the amount of material should not be too much each time, otherwise the coarse material below will block the fine material from going down, and the screening of the material will not be complete; (2) It is labor-intensive. When sieving materials, it is necessary to use both hands to hold the sieve back and forth, and at the same time bear the weight of the materials; (3...

AI Technical Summary

Problems solved by technology

Since there is only one contact surface between the screen and the material, the amount of material put in each time should not be too much, otherwise the coarse material below will block the fine material from going down, and the material screening will not be complete; (2) It is labor-intensive

When sieving materials, it is necessary to use both hands to hold the sieve back and forth, and at the same time bear the weight of the materials; (3) The utilization efficiency of the screen is low

The contact surface between the sieve and the material is limited, the coarse material blocks the sieve hole, and the fine material should not be sieved out

When the material is sand and soil with high water content, the above problems will become more obvious, and the sieve hole will be blocked seriously, and the screening operation will be difficult.
