Powder material collecting cabin

Abstract

The invention relates to a powder material collecting cabin. A dust removing device and a weighing device are arranged in a cabin body, an upper end opening of a conical flow guide tube of the dust removing device is connected with the top surface of the cabin body, a lower end opening of the conical flow guide tube is connected with a cylindrical flow guide tube, an outlet of a material conveying pipe is arranged in the cabin body, the arrangement height of the outlet of the material conveying pipe is greater than the lower end opening of the conical flow guide tube, the arrangement direction of the outlet of the material conveying pipe is parallel to the tangent line direction of the circumference of the cabin body, the weighing device comprises a measuring tube, a support frame, a pressure bearing plate, a sealing rubber cap and at least three pressure sensors, the measuring tube is vertically arranged on the side wall of the funnel-shaped part of the cabin body, the support frame is horizontally arranged in the measuring tube, the pressure sensors are circularly distributed at the upper end of the support frame, the sealing rubber cap is arranged at the upper end opening of the measuring tube, and the pressure bearing plate is arranged between the sealing rubber cap and the pressure sensors. The solid powder body can be separated from the air flow to the furthest degree, the dust quantity of the flowing direction exhaust opening is reduced, in addition, the powder material quantity in the cabin body can be accurately measured, and the production is convenient to control.

Description

technical field [0001] The invention relates to a feed bin, in particular to a powder material collection bin. Background technique [0002] In cement and other powder production or powder processing industries, the produced powder is usually stored in a powder silo conveyed by wind. After the powder enters the powder silo, the airflow used for transportation is exhausted from the upper end of the powder silo. Due to the impact of the airflow during the conveying process, a large amount of powder in the powder silo will flow to the air outlet with the airflow before it sinks. Therefore, the dust filter device at the air outlet is often blocked by a large amount of dust, resulting in failure. production, seriously affecting production efficiency. Moreover, the existing powder silos are all closed structures, and the judgment of the amount of powder in the silo is usually measured by a level gauge, which is generally arranged on the inner wall of the powder silo. For exa...

Problems solved by technology

Therefore, the method of setting the level gauge can only determine whether the powder is above or below the level gauge, and cannot accurately determine the amount of powder, which is not conducive to controlling production
