Embodiment Construction

[0013] The non-powered dust removal device of the present invention utilizes the physical siphon principle and energy conservation principle applied in the above-mentioned prior art, adopts a relatively sealed structure, and sets an environment where the dust energy is depleted, so that the dust falls back on the transmission belt regularly to complete effective dust removal. In the non-powered dedusting device of the present invention, a dust return-shaped revolving channel is set, and no dust-proof curtain is installed at the material outlet of the revolving-shaped dust revolving channel, and the method of step-down dust removal and synchronous multi-channel dust removal is adopted, which not only solves the problem of coal dust The deflagration problem makes the dust removal effect more ideal, which can fully meet the requirements of GB16248-1996 "Hygienic Standards for Respirable Dust in Air in Workplaces".

[0014] A detailed description will be made below in conjunction w...

Abstract

The invention relates to an unpowered dust removal device which is characterized in that a material guide groove is arranged between an uploading belt and a downloading belt, the material guide groove is communicated with a catching groove above the downloading belt, and the dust removal device is provided an ash cyclic channel which is communicated with the material guide groove and is in the shape of a Chinese character 'Hui', a plurality of external cyclic dust chambers and a plurality of dust blocking curtains; the material guide groove, the ash cyclic channel in the shape of a Chinese character 'Hui' and the external cyclic dust chambers are sequentially arranged on the catching groove above the downloading belt, and the bottom of the dust removal device is communicated with the catching groove above the downloading belt; and the interior shape of the external cyclic dust chambers can be a right angle, an obtuse angle, an acute angle, a semicircle or a 3 / 4 circle. The unpowered dust removal device realizes multi-way synchronous dust removal, solves the problem of deflagration in the process of coal transmission and dust removal, and enables the dust removal effect to meet the requirements of GB16248-1996 Health Standard for Respirable Dust in the Air of Workplace.

Description

technical field [0001] The invention relates to a dust removal device used in the belt transmission and transshipment process of industries such as power generation, steel, coal, mines, cement, flour, ports, etc., in particular to a non-powered dust removal device. Background technique [0002] In order to solve the dust problem at the drop point (transfer station) during belt transportation, there are roughly two types of domestic solutions for dealing with this type of dust. One is the traditional dust removal method: bag dust removal, multi-tube dust removal, electrostatic dust removal, etc. Traditional dedusting methods have large power consumption, high maintenance costs, and secondary emission pollution. The other is a new type of dust removal method, the unpowered dust collector. This dust removal method mainly uses the principle of physical siphon and energy conservation principle, etc., so that the dust can effectively circulate in the sealed channel, so that the d...
