Abstract

The utility model discloses a dust removal device, which comprises a main box body (1), as well as an air inlet and an air outlet which are formed at the top end of the main box body (1) and communicated with the main box body (1). A plurality of cylindrical filter screens (2) are vertically arranged inside the main box body (1); a pneumatic device is arranged at the connection of cylindrical filter screens (2) and the main box body (1); the pneumatic device comprises a pulse valve (4) and a high pressure air tube (3) connected with the pulse valve (4) ; the pulse valve (4) is arranged on the connecting device of the filter screens (4) and the main box body (1) at one end near the top part of the main box body (1); the high pressure air tube (3) passes through the cylindrical filter screens (2); a cone (6) with four walls shrinking downwards is arranged at the bottom part of the main box body (1); the bottom part of the cone (6) is connected with a conduit (8); a dust collection box (5) is connected with the outlet of the conduit; and a valve (7) is further arranged on the conduit. Due to the adoption of the device provided by the utility model, the disadvantages of universal equipment are overcome, the dust accumulation is prevented, the long-time continuous operation is achived, and the continuity of production is ensured.

Description

A kind of dust arrester

Technical field

The utility model relates to pharmaceutical equipment, relates in particular to a kind of dust arrester.

Background technology

The film clothing machine course of work produces a certain amount of dust fast; the supporting dust arrester of main frame is box deduster; by casing and give vent to anger and air inlet pipe form; there is the tubular filter screen of some in the vertically equal portion that is connected with box sealing in the casing; dust is adsorbed on the filter screen; adsorbing a certain amount of dust filter screen will stop up; do not reach the purpose of dedusting, dust will be led out, contaminated environment; the general method of changing filter screen that adopts solves; changing filter screen must shut down, and influence is produced, sometimes in order just not influence the tablet at dressing; produce the vibrations solution to beat casing; not only equipment is caused percussion mark, even the meeting damage equipment, the medicinal powder that vibrations come off is mingled with the control of dust of equipment; can not continue reuse, cause waste.

Summary of the invention

Problem to be solved in the utility model provides a kind of dust arrester, and purpose is to overcome above-mentioned defective, keeps ordinary production.

To achieve these goals, the technical scheme that the utility model is taked is: a kind of dust arrester that is provided, comprise main box and be arranged at air inlet, air outlet the main box top and that communicate with it, main box inside vertically is provided with a plurality of tubular filter screens, and described tubular filter screen junction is provided with pneumatic means.

Described pneumatic means is made of pulse valve and connected high-pressure air pipe, and pulse valve is arranged on the jockey of filter screen and casing near main box top one end, and high-pressure air pipe feeds the tubular filter screen.

Described main box bottom is provided with the cone that wall shrinks around downwards, and cone base connects a conduit, and the conduit outlet place connects a disposal box, also is provided with valve on the conduit.

The jockey of described tubular filter screen and casing is tightly connected.

Described tubular filter screen is set to 9～12.

Adopt technique scheme, the tubular filter screen is provided with pulse valve, pulse valve connects high pressure gas, timing starting impulse valve, and high pressure gas feeds filter screen, to be adsorbed in online medicinal powder blows off, conduit is collected and fallen into to cone by the main box bottom, regularly opens the valve that is provided with on the conduit, in the disposal box with the medicinal powder collection, overcome the defective of stopping up the replacing that to stop production because of filter screen, prevent dust accumulation, stop up and influence air-flow, thereby but the long-time continuous operation, the more thorough pollution of avoiding environment of dedusting simultaneously, guaranteed the continuity of producing, the medicinal powder of collection does not pollute in the whole enclosed environment, can reuse, save raw material, reduced cost.
