Embodiment Construction
[0013] The pressure-balanced non-powered dedusting device of the present invention utilizes the physical siphon principle, the principle of energy conservation and the theory of gas-dust separation, through the pressure-balanced non-powered dedusting device, the environment in which the dust energy is exhausted and the clean gas with energy flows out makes the dust Regularly fall back on the transfer belt to complete effective dust removal. In the invention of the pressure balance type non-powered dust removal device, the gas and dust separation method is used to quickly balance the air pressure in the buckle tank with the atmospheric pressure of the outside air, so that the dust energy is quickly exhausted, and the dust is no longer raised. The way of reducing dust and dust removal solves the problem The dust explosion problem of coal dust also greatly shortens the dust removal process, makes the dust removal process more intuitive, saves a lot of materials and reduces equipme...

The invention relates to a pressure-balanced unpowered dedusting device, which is characterized in that: a material guiding groove is arranged between an upper conveyor belt and a lower conveyor belt; catching grooves are formed above the lower conveyor belt; a gas-dust separation chamber, a dust-gas separation spiral channel in a shape like a Chinese character 'hui', a reciprocating gas-dust separation chamber and a decompression device are arranged in the advancing direction of the lower conveyor belt in turn; the bottom of the reciprocating gas-dust separation chamber is communicated with the catching groove; the upper part of the dust-gas separation spiral channel in the shape like the Chinese character 'hui' is communicated with the material guiding groove; the lower part of the gas-dust separation chamber is provided with a dust curtain I arranged in a catching groove; and the dust curtain I, a dust curtain II, a dust curtain III and a dust curtain IV are arranged in catching grooves on the lower parts of the gas-dust separation chamber, the dust-gas separation spiral channel in a shape like the Chinese character 'hui', the reciprocating gas-dust separation chamber and the decompression device. The pressure-balanced unpowered dedusting device solves the problem of dust explosion in the coal transporting and dusting process, the dedusting process is greatly shortened, the dedusting effect is more ideal and more complete, materials are saved and equipment cost is reduced.
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 pressure-balanced non-powered dust removal device. Background technique [0002] In order to solve the problem of dust at drop points or transfer stations during belt transportation, a new type of dust removal method for dealing with such dust in China is a non-powered 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 set sealed channel, so that the dust energy is exhausted and falls back to the belt to complete the dust removal. Unpowered dust removal is completely a zero-carbon dust removal method. After retrieving Chinese patents, in the known technology, non-powered dust removal is used to manufacture airtight materi...
