Dedusting system for sample making chamber

Abstract

The invention discloses a dedusting system for a sample making chamber, which comprises a dedusting main machine, a dedusting main pipe and a plurality of sample crushing devices, wherein a channel of the dedusting main machine is internally provided with a filter screen and an exhaust fan; the dedusting main pipe is connected with an inlet of the dedusting main machine, the dedusting main pipe is provided with a plurality of internal dust source sucking devices and a plurality of external dust source sucking devices, wherein each internal dust source sucking device comprises a settling chamber, a primary filter screen arranged in the settling chamber and a dust collecting hopper arranged at the bottom of the settling chamber; and an internal dust source cavity of each sample crushing device is communicated with a dust sucking hole of each internal dust source sucking device. By adopting a progressive filtering and progressive collecting manner, the dedusting system for the sample making chamber, provided by the embodiment of the invention, reduces the load of a filter, lowers the probability of the blockage of a dedusting pipeline, and lightens the wear to the dedusting pipeline.

Description

technical field [0001] The invention relates to the technical field of dust removal, and more specifically, to a dust removal system for a sample preparation room. Background technique [0002] Sample preparation is the process of making the sample reach the state of analysis or test. The purpose of sample preparation is to prepare the collected sample into an analytical sample that can represent the characteristics of the original sample through steps such as crushing, mixing, shrinking and drying. The crushing of the sample is mainly to use the sample preparation crushing equipment (such as a crusher) to make the large particle sample into a small particle sample through extrusion, impact, cutting and other operations. During the crushing process, a small part of the sample with a diameter of 100 μm ~ Very small particles of 10 μm, that is, dust. Due to the vibration of the crushing equipment during the working process, the dust will leak from the gaps of the crushing equ...
