Abstract

The invention discloses a dust detecting and screening device. The device comprises a base and a dust removing box, a rotating shaft is arranged in the dust removing box, a screening mesh cylinder sleeves the rotating shaft, a lifting machine is arranged on the outer side of the dust removing box, a feeding pipe is arranged on the lifting machine, and the feeding pipe penetrates through a sealingcover to communicate with the dust removing box; the screening mesh cylinder comprises screening mesh plates, supporting rods and two fixing plates, the screening mesh plates and the supporting rods are connected between the two fixing plates in a bridging mode, feeding holes are formed in the tops of the screening mesh plates, each supporting rod is hollow, air outlet holes are formed in the sidewalls of the supporting rods, the end parts of the supporting rods are connected with guide pipes, and the guide pipes communicate with air bags arranged on the inner side wall of the dust removing box; a section of transparent pipe is introduced into the portion, close to the sealing cover, of the feeding pipe, a branch pipe communicates with the lower side surface of the transparent pipe, the upper side surface of the transparent pipe is correspondingly provided with a light-emitting device and a photoelectric conversion device, the photoelectric conversion device is connected with an ampere meter, the ampere meter is connected with a regulating valve, and the regulating valve controls closing of the branch pipe and the feeding pipe. According to the device, whether dust in grain exceeds the standard or not can be detected, and automatic dust removing can be carried out after the standard-exceeding judgment is made.

Description

technical field [0001] The invention belongs to the technical field of dust detection, and specifically discloses a dust detection and filtering device. Background technique [0002] Grain dust explosion has always been a potential safety hazard in grain processing, storage, transportation and bulk grain loading and unloading. Grain dust is a kind of non-conductive combustible dust. Dust will inevitably be generated during grain warehousing and processing, and exists in the form of dust cloud or dust layer in the production site. After mixing with air, grain dust reaches At a certain concentration, if it encounters an ignition source with sufficient energy, it may be ignited and a dust explosion with great destructive power will occur. In addition, a large amount of mixed dust will be generated during the process of grain entering and leaving the warehouse, flat stacking, turning the grain surface, raking, and processing, such as grain shells, skins, burrs, flour, bran, bra...
