SU1430071A2 - Filter for cleaning gases - Google Patents

Abstract

The ejection relates to the purification of gases from dust in the systems of aspiration, pneumatic transport, both vacuum and pressure, and makes it possible to improve the filtration conditions. The filter includes a housing, a cone sleeve with a valve and means for regeneration in the form of a stretching spring, connected to the valve of the sleeve and the housing, with plate valves attached to both sides of the stretching spring, with curved ends carrying rotation stops, and hinged slats which are included in the gaps between the turns of the expansion spring. When the spring lengthens, the hinge plates fall off the coils, jump onto its other coils, causing the spring to oscillate and the sleeve to slip during the operation of the filter and regenerate it without interrupting the cleaning process. 2 Il. with SS

Description

M

The invention relates to the purification of gases from dust in aspiration systems, as well as in the dax system of pneumatic conveying, both vacuum and pressure.

The purpose of the invention is to improve the filtration conditions.

FIG. 1 shows a filter diagram, general view; in fig. 2 — node I FIG. 1, 1. I The filter comprises a housing 1, a cone-porous sleeve 2 and a means for regeneration 3. A casing 4, fitted with an outlet nipple 5, is installed in the upper part of the orpus 1. In the bottom part of the sleeve 2, a valve 6 is fixed, made, for example, in the form of a plate. On the inner side of the valve 6 (the spring 7 is installed, the extension of the coral by the second end is connected to the housing AND by a jumper 8. The means for regeneration is made in the form of the vertical plate spring springs 9 rigidly attached to the valve 6 with | the ends bent at the ends which pivotally mounted strips 10, contact- ing with the coils of the spring 7. The plates U periodically contact with one-sided turn-stop 11 mounted on the springs 9.

to determine the pressure drop above and below the sleeve. The internal pressure increases the sleeve, the spring 7 is expanded, and the hinged plates 10 of the springs 9 jump over the coils of the spring 7, wringing out its intense core and, accordingly, shaking 10

- The operation of the sleeve 2. The dust in the form of lumps falls down on the sleeve, the resistance of the sleeve decreases, as a result of which the sleeve is lowered by the action of the spring 7, its mass and the weight of the valve 6. The hinged bars 10, while turning upwards, do not prevent the shortening of the spring 7.

When the lengths of the springs are performed 9 times, the range of amplitudes of oscillations of the spring 7 and springs 9 increases by a large amount, which improves the conditions for regeneration of the sleeve.

Technical and economic efficiency; The proposed filter is to improve the filtering conditions, which is caused by periodic shaking of the sleeve as the filter is operated using plate springs when they engage the coils of the extension spring. This reduces the filter resistance on average ds 25-30% and provides improved operation of the ventilation system. With an increased flow rate of the gas to be filtered and a high degree of its dustiness, the proposed means for regeneration makes it possible to increase the duration of the continuous operation of the filter by 2 times.
