Description

Technical Field

[0001] The utility model relates to the technical field of screening machines, in particular to a screening machine capable of avoiding screen mesh clogging. Background Art

[0002] During the salt processing process, a screening machine is needed to remove large, clumped, and agglomerated salt particles to prevent them from affecting subsequent processing. The salt particles can also be graded and screened to make the finished salt particles uniform.

[0003] After searching, the existing Chinese patent with publication number CN201720600419.X discloses a layered rotary screening device for salt screening. The filter motor and the conveying motor are turned on by the control switch, and the salt is poured into the screening bin through the feed pipe. As the coarse filter, semi-fine filter and fine filter rotate, the filtration is completed. The filtered salt is sent to the finished product bin through the discharge pipe by the rotation of the finished product recovery plate. The semi-finished products on the coarse filter, semi-fine filter and fine filter will enter the discharge pipe through the centrifugal action and finally flow into the spiral conveyor belt. The spiral conveyor belt is provided with grooves. Large particles will flow directly into the recovery bin, and small particles will continue to flow into the feed pipe through the spiral conveyor belt to complete the secondary filtration, and the layered rotary filtration of salt is completed in a cycle.

[0004] The above technical solution has the following defects: although such a screening machine structure can screen the salt in layers through multiple groups of screening filters, in actual use, the screens are parallel in structure, and the internal salt particles are easily stuck in the screen holes. In order to avoid screen blockage, a screening machine that can avoid screen blockage is proposed. The machine is provided with multiple groups of screen cylinders that are easy to disassemble and assemble. Multiple groups of filters with different screen hole diameters can be assembled according to actual requirements, so that the screening machine can grade and screen salt with different particle diameters according to needs. The overall structure is inclined, and the screen is an arc-shaped structure, so that the salt can be quickly screened in multiple stages in the vibrating and rotating screening structure, and can effectively prevent the screen from being blocked, with better screening efficiency.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and combines theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.
