Description

TECHNICAL FIELD

[0001] The utility model relates to zeolite molecular sieve technical field, concretely is a kind of zeolite molecular sieve raw material grinding device. BACKGROUND

[0002] Zeolite molecular sieve is a kind of crystal material with microporous structure, its unique framework structure makes it have selective adsorption, catalysis and ion exchange function, so it plays an important role in petroleum chemical industry, gas purification, environmental protection and other fields.Zeolite molecular sieve is composed of silicate, and its structure contains regular channels and cavities.Through these channels, zeolite can selectively adsorb molecules of a certain size, so it is widely used in dehydration and purification process.In the process of processing zeolite raw material into zeolite molecular sieve product, a key step is to crush the zeolite raw material.The goal of crushing is to obtain zeolite particles of appropriate particle size, so as to improve its performance in practical application.

[0004] Although the above-mentioned prior art sets dust filter cloth on the receiving bin to block dust, but there are still significant defects and deficiencies in actual use.Specifically, when the receiving bin is gradually filled with zeolite fragments, the dust filter cloth is easily blocked, which greatly reduces its dustproof effect.The abrasion caused by the continuous contact of the dust filter cloth with zeolite particles also makes it lose its function quickly, resulting in ineffective dust blocking and aggravating environmental pollution.When the dust filter cloth is blocked, a large amount of dust will accumulate in the receiving bin and the box, and when the worker removes the receiving bin, a large amount of dust will be scattered, causing the worker to inhale the dust.In addition, the dust generated during the crushing process not only escapes along the receiving bin, but also may overflow from the feeding port of the device.These dusts suspended in the air will accumulate over time, causing a serious decline in air quality around the equipment, which poses a serious threat to the respiratory health of workers working in such an environment.For this reason, we propose a kind of zeolite molecular sieve raw material grinding device.
