Sampling mechanism for cement clinker grinding equipment

Abstract

The invention discloses a sampling mechanism for cement clinker grinding equipment. The sampling mechanism comprises a shell, a sampling barrel and a division bar for separating an end opening of the sampling barrel, a U-shaped sealing plug which slides linearly and is matched with the division bar is arranged in the sampling barrel; the bottom of the sealing plug is rotationally and movably connected with a fixed rod; the fixed rod is in threaded connection with a fixed disc; an exhaust port and an air inlet are respectively formed in two sides of the sampling barrel on the linear motion trail in the U-shaped area of the sealing plug; the air inlet is connected with an air pump set and an inlet of a storage box through air pipes. An outlet of the storage box is connected with the exhaust port through an air pipe; the storage box is in shaft connection with a U-shaped bracket; along with the rotation of the shell, the storage box is always vertically arranged relative to the ground; a filter plate is arranged in the storage box; through holes are formed in the surfaces of the filter plate. The particles are blown out by the circulating air flow, and cement powder in the whole ball mill is comprehensively sampled along with rotation of the ball mill. The cement dust is deposited in a layered precipitation manner, so that different granularities of the cement powder can be directly obtained.

Description

technical field [0001] The invention relates to the field of cement clinker grinding and sampling, in particular to a sampling mechanism using cement clinker grinding equipment. Background technique [0002] Cement clinker is an important product in cement processing technology. At present, ball mills are mostly used to complete the grinding work of cement clinker. In the process of cement grinding, it takes a long time to pay attention to the results of cement grinding. Especially in the process of cement test, it is necessary to take out real-time grinding samples from the pulverizer at any time and comprehensively for inspection. However, at present, the pulverizer usually only has a grinding power supply, and it is relatively difficult to sample the cement in the pulverizer. The current practice is to take out part of the clinker samples from the feed port after the machine is shut down. However, this method of retrieving materials has many defects: 1. When the pulve...

AI Technical Summary

Problems solved by technology

However, this method of retrieving materials has many defects: 1. When the pulverizer is turned on when retrieving materials, there will be a lot of dust leakage, which will cause harm to the working environment

2. The obtained powder is in the shutdown state, and the sampling of the powder in the whole pulverizer is not comprehensive

3. After taking the material, the powder needs to be sieved, which will cause secondary dust to fly and affect the health of workers
