Simple drum type sieve

Abstract

The invention relates to a material sieving tool, in particular to a simple drum type sieve. The simple drum type sieve comprises a sieve drum, a sieve drum center shaft, a material receiving box and a rotating device, wherein the sieve drum is installed on the material receiving box through the sieve drum center shaft; any end of the sieve drum is provided with a feed port; any end of the sieve drum center shaft is connected with the rotating device; the sieve drum is driven by the rotating device to rotate around the sieve drum center shaft as a center. The simple drum type sieve is simple in structure and low in production cost; every time, more materials can be sieved with less labor; the utilization efficiency of a sieve net is improved; the heavy work of sieving operation is lightened.

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 material input is small each time. 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 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 ut...

AI Technical Summary

Problems solved by technology

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 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.
