Problems solved by technology

The auxiliary function of the pressure difference sensor effectively reduces the number of pulse cleaning, but the pressure difference changes greatly, which affects the effect of powder selection. The thickness of the powder product is uneven, or the powder content of the product after dust removal is uneven, which affects the quality.

Abstract

The invention provides a dust collector control method, a dust removal device, a dust collector and a readable storage medium. A control method for a dust collector. The dust collector includes a plurality of dust removal chambers. The dust collector is provided with an air inlet and an air outlet. The control method includes: obtaining the actual pressure difference between the air inlet and the air outlet of the dust collector; According to the set pressure difference, the correction cycle is obtained; according to the dust cleaning cycle and calibration cycle of the previous dust removal room, the target dust removal cycle of the current dust removal room is obtained; according to the target dust removal cycle, the current dust removal room is controlled to perform dust removal. The technical scheme of the present invention adopts a suitable dust removal cycle for filter bag pulse injection, which can effectively clean the filter bag, improve the use efficiency of the dust collector and the service life of the filter bag.

Description

technical field [0001] The present invention relates to the technical field of dust collectors, in particular, to a control method of a dust collector, a dust cleaning device, a dust collector and a readable storage medium. Background technique [0002] In the related art, the dust cleaning system of the dust collector can adopt the timing mode, that is, the frequency of pulse cleaning is fixed, and the dust cleaning system of the dust collector can also be equipped with a pressure difference sensor, that is, the pressure difference is higher than the upper limit, and the dust is cleaned with a high pulse fixed frequency. The difference is below the lower limit with a low pulse fixed frequency. Although the timing control of cleaning is simple, it is not economical. If the set time interval is too long, too much dust is deposited on the filter bag, and the pressure difference is too large, which cannot achieve good powder selection and dust removal effects. Too much and the...
