Description

Pre-processor for smoke purifier

Technical Field

The invention belongs to the technical field of air purification devices, and particularly relates to a preprocessor for a smoke purifier.

Background

During the cutting, welding and polishing operations on mechanical workpieces, a large amount of smoke is generated, and at the moment, a smoke purifier is usually installed in an operating room to filter out smoke particles contained in air. The smoke dust purifier usually filters smoke dust by using a film-coated filter cylinder, and discharges clean air after the filtering is finished so as to realize air self-circulation in an operation room. The film-coated filter cartridge has good filtering effect on smoke dust with the particle diameter of 0.1-1 micron. If the particle diameter of the soot is 1 to 10 microns, the soot is directly filtered by the membrane-coated filter cartridge without pretreatment, and the membrane-coated filter cartridge is easily blocked, so that the membrane-coated filter cartridge fails. Therefore, there is a need for a preconditioner for soot purifiers.

As shown in fig. 1 to 3, a preprocessor for a smoke purifier comprises an outer shell 1 which is hollow inside and has an open bottom end, wherein an inner shell 2 is fixedly sleeved inside the outer shell 1, an air flow channel 3 is arranged between the inner shell 2 and the outer shell 1, a blocking wall 4 is fixedly sleeved inside the inner shell 2, the air flow channel 3 is arranged between the blocking wall 4 and the inner shell 2, the inner shell 2 and the blocking wall 4 are both of hollow structures with open top surfaces and open bottom surfaces, the side surface of the inner shell 2 is connected with an air inlet pipeline 5, the air inlet pipeline 5 penetrates through the side surface of the outer shell 1, and the bottom of the blocking wall 4 is lower than the air inlet pipeline 5.

The working principle is as follows: the air mixed with the smoke dust enters the air flow channel from the air inlet pipeline under the action of negative pressure, and dust particles with larger volume are blocked by the blocking wall and can fall to the bottom of the inner shell downwards under the action of gravity; the smoke dust with the larger particles removed continuously flows along the airflow channel, finally flows out of the bottom of the shell, then continuously flows into the film-coated filter cylinder, filters the smoke dust with the smaller particles, and finally discharges the purified air. The pre-processor for the smoke dust purifier can effectively clean smoke dust with larger particles, avoids the blockage of the film-coated filter cylinder by the large-particle smoke dust, and prolongs the service life of the whole smoke dust purifier.

The inner part of the inner shell 2 is fixedly sleeved with a plurality of blocking walls 4 from top to bottom, the side surfaces of the inner shell 2 are correspondingly connected with air inlet pipelines 5 with the same number as the blocking walls 4, and the height of the bottom of each blocking wall 4 is lower than that of the corresponding air inlet pipeline 5.
