A sampling mechanism for cement clinker grinding equipment

Abstract

The invention discloses a sampling mechanism for cement clinker grinding equipment, which comprises a shell, a sampling cylinder, and a spacer separating the ports of the sampling cylinder; a U-shaped sealing plug that slides linearly and coincides with the spacer is arranged in the sampling cylinder , the bottom of the sealing plug is rotatably connected to the fixed rod; the fixed rod is threadedly connected to the fixed plate; the two sides of the sampling cylinder with the linear motion track in the U-shaped area of ​​the sealing plug are respectively provided with an exhaust port and an air inlet; It is connected with the inlet of the air pump group and the storage box; the outlet of the storage box is connected with the exhaust port through the air pipe; the storage box is connected with the U-shaped bracket shaft; with the rotation of the shell, the storage box is always vertically set relative to the ground; A filter plate is provided; the surface of the filter plate is provided with through holes. The circulating air blows the particles out, and with the rotation of the ball mill, the cement powder in the whole ball mill is sampled comprehensively. Then the cement dust is deposited by layered precipitation, and the different particle sizes of the cement powder can be obtained directly.

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
