SU1554946A1 - Self-cleaning filter device for cleaning air from fibrous dust - Google Patents

Abstract

The invention relates to filtering air from fiber dusts and can be used in various industries. Its use will reduce the complexity and improve dust disposal. A self-cleaning filtering device for air purification from fibrous dust includes a filtering belt strung on shafts, formed from endless threads strung on washers of larger and smaller diameters, alternately placed on shafts. The device is equipped with a grid and a comb placed under the tape, the tooth of which is mounted between washers of a larger diameter. The air duct is made in the form of a cochlea, the threads of the tape are located on washers of a smaller diameter, and the tape moves continuously along the flow of the air being cleaned. 3 il.

Description

This invention relates to the filtration of air from fiber dusts and may find application in various industries.

The aim of the invention is to reduce the labor intensity and improve the utilization of dust.

FIG. Figure 1 shows the proposed device, the general view, in Figure 2 - the moment of regeneration of the filtering tape} in FIG. 3 - a fragment of a shaft with tension of the threads between the washers.

The device for air purification from fibrous dust contains filtering belt 1 pulled on shafts, formed from endless threads pulled on smaller diameter washers 2 between larger diameter washers 3, while the tooth of comb 4 is located

between larger washers. The washers of two sizes, the comb and the guides 5 constitute the disposal unit 6. The shape and stability of the filtering web is provided by the support grid 7 and the tension assembly 8 for endless filaments. The inlet duct 9 is designed as a cochlea. The bed 10 of the deposited dust is picked up by the comb 4 and transported by the rollers 11, folding along the guides 5 into a roll.

The device works as follows.

The dusty gas stream is directed to the supplying helix-shaped duct 9 in the direction of movement of the filtering tape 1, which moves on the shafts continuously. Dust settles

on the tape made of parallel filaments supported on the support grid, the teeth of the comb 4 are removed, passed through the rollers 11, and along the guides 5 the mass of dust is rolled into a roll or stitched into the tape by known devices.

When operating, a dense layer of fibrous dust is formed on the surface of the web. The lower part of the layer consists of long-length dust, which is deposited by the centrifugal saw of the filtered air flow in the cochlea. The upper part of the layer consists of finer dust, which is deposited due to the filtering effect of the web and precipitated long dust. When a layer of dust approaches the lead roller, the threads round the washers of a small diameter, and the washers of a larger diameter separate the dense layer of dust from the webs. The comb removes a layer of dust from the crests of a larger diameter uanCu (and not from the filtering layer) and directs it to a pushing system for further utilization. The resulting dense strip of precipitated dust is conveniently rolled into a roll, which, if this device is not associated with mechanisms processing dust (waste), is convenient for packing into bags, drums, and the like, which helps prevent dusting the air after the cleaning process. At the same time, initially deposited on the filter

a ribbon of lengthy dust fraction reinforces it and forms a layer filtering smaller dust fractions.

The effectiveness of the filtering process depends on the conditions of formation of the lower layer of long dust and depends on the conditions of formation of the lower layer of long dust and the speed of movement of the filter sheet, which is constantly in motion, which ensures its constant regeneration and reduction of labor intensity, as well as improved dust utilization.
