Description

Technical Field

[0001] The utility model belongs to the technical field of dust collectors, and in particular relates to a dust collector control device. Background Art

[0002] At present, the main mode of transportation for the delivery of lime from the finished product warehouse is automobile transportation. During the process of loading lime powder by automobile, a large amount of dust will spread to the surroundings between the discharge port at the bottom of the lime warehouse and the feeding port of the automobile. These dusts will pollute the surrounding environment. In order to reduce pollution, dust removal points are set around the discharge port at the bottom of the lime warehouse and the feeding port of the automobile to collect dust. The dust removal point shares a dust collector with the dust removal point of the finished product warehouse belt system. Since the loading of automobiles is intermittent, if the dust removal valve of the dust removal point is kept open, it will cause a waste of electricity during the period of non-discharging, and affect the dust removal effect of other dust removal points.

[0005] In a feasible technical solution, in order to achieve convenient adjustment of the force applied to the spring, the annular protrusion is connected to the inner wall of the housing via a thread.

[0006] In a feasible technical solution, in order to facilitate the disassembly and assembly of the sensor or the sensing plate, the shell includes a lower shell and an upper shell; the connecting portion between the lower shell and the upper shell is provided with a raised ring extending outward, a connecting hole is opened on the raised ring, and the two raised rings are connected by bolts.
