AI Technical Summary

Technical Problem

During the production and screening of calcium carbonate, the existing technology is difficult to reasonably control the vacuuming condition, resulting in excessive or insufficient suction force, and the inability to effectively capture and remove dust, which increases environmental pollution and health risks, and reduces resource utilization and production efficiency.

Method used

A dust regeneration device for the production and screening of calcium carbonate is designed, including a vibrating screen body, a dust guide cylinder, an air flow fan, a collection box and a tension sensor. Through the coordination of the rectangular holes on the upper part of the dust guide cylinder and an air flow fan, the effective absorption and separation of dust is achieved, and the problem of excessive or insufficient suction is avoided.

Benefits of technology

It effectively avoids the loss of useful materials caused by excessive suction and the incomplete dust trap caused by insufficient suction, improves the efficiency of dust treatment and separation, reduces environmental pollution and health risks, and improves resource utilization and production efficiency.

Abstract

The invention discloses a dust regeneration device for calcium carbonate production screening, and relates to the technical field of screening, the dust regeneration device comprises a vibrating screen body, the vibrating screen body is fixedly connected with a screen, the vibrating screen body is provided with a dust guide cylinder, the upper part of the dust guide cylinder is provided with rectangular holes distributed in the circumferential direction, and the dust guide cylinder is fixedly connected with a cover cylinder; the dust guide cylinder is fixedly connected with a fixing plate, through holes distributed in the circumferential direction are formed in the fixing plate, and the fixing plate is fixedly connected with an airflow fan distributed in the circumferential direction. When an external dust collector and an airflow fan are used for collecting dust raised by calcium carbonate, the dust sequentially bypasses the inner wall of the dust guide barrel and a rectangular hole in the upper portion of the dust guide barrel and then is sucked downwards by the airflow fan, and the situation that an air pipe of the dust collector directly sucks the dust towards a screen, so that suction force is too large, and non-floating calcium carbonate powder is also sucked away is avoided; or the situation that dust generated in the screening process cannot be effectively captured and removed due to insufficient suction force due to the fact that an air pipe of the dust collector is too far away from the screen is avoided.
