Abstract

The invention discloses an FSQC pulse dust collector, which is newly successfully-developed high-efficiency chamber dust cleaning and recycling equipment for the industries of grain processing and the like, can recycle both dry dust and moist dust and has an effect irreplaceable by the traditional dust collector. The FSQC pulse dust collector structurally comprises a box body, a filter cartridge and a dust cleaning device, wherein the box body comprises an upper part, a middle part and a lower part; and the filter cartridge is prepared through folding by adopting a special process and special high-density stainless steel wire cloth used as a filter material, and the crests inside and outside the filter cartridge are in circular arc shape and are subjected to special treatment so as to prevent the generation of fatigue cracks. After entering an air duct from the outer side of the box body, dust-containing air diffuses and slowly enters surrounding space of the filter cartridge, enters an air duct of the upper box body after being filtered by the filter cartridge and is exhausted to the atmosphere by a fan, and fine dust is blocked and attaches to the outer surface of a filter screen. In order to ensure the favorable air permeability of the filter cartridge, a chamber exhaust valve is closed instantly before dust cleaning, and an electromagnetic control valve automatically releases compressed air in a fixed time so as to reversely blast the filter cartridge for generating vibration to blow off the fine dust attached to the outer surface of the filter screen, enable the fine dust to fall into a dust hopper of the box body and exhaust the fine dust from a rotary feeder.

Description

The FSQC pulse dust collector

Technical field

The FSQC pulse dust collector is to do filtering material with special special-purpose high density stainless steel wire cloth, this cleaner, it is not subjected to the restriction of environment for use, dust characteristic, recovery to dry dust, wet dust all can reach splendid recovering effect, and especially the recovery to wet dust plays the irreplaceable effect of other pulse dust collectors up till now.

Background information

At present, industries such as cereal processing both at home and abroad, food are used for directly or double purification reclaims the pulse dust collector of various Work machines at the dust of producing the running generation, and the fabric that generally adopts polyester flannel and so on is as filter pocket material.Generally pretty good to reclaiming the dry dust effect, but commute produces the Work machine dust of aqueous vapor to be reclaimed unsatisfactory, such as the cereal pulverizer, after measured when pulverizing the main material corn, because corn flour is broken into corn flour, under the situation of standard moisture content, cause losing the moisture content about 0.2-0.3%, the moisture content of loss becomes aqueous vapor, the overwhelming majority enters atmosphere by blower fan, can still have the sub-fraction aqueous vapor when passing filter bag, be trapped in the flannelette fiber, just stick together with fine dust, how long do not cross, filter bag outer surface fiber has been tied the wet piece of a thick layer of approximate pasty state, has a strong impact on the gas permeability of filter bag, has to often change clean.And for knowing perfectly well and wherein still contain fine wet dust through just purifying the hot humid air that enters atmosphere in the cooling system, can have the fibrous filter pocket type pulsed dust collector now all can't reclaim, let alone to enter atmosphere.

Summary of the invention

Defective in the face of present normal pulsed deduster existence, we further investigate the dust-filtering material, it is on probation to comprise that the long fibre polyester non-woven fabric all compares, finishing screen is selected with special special-purpose high density stainless steel wire cloth and done filtering material, and is ideal with the pulse dust collector that the folding filter cylinder that forms of special process combines.

Its general structure is made up of casing, filter cylinder, dust cleaner three parts:

Casing: form by upper box, middle casing, lower box.Upper box is formed by being separated into some groups of float air channels.Be the fixing card of filter cylinder between upper box and the middle casing.Lower box is made up of dust hopper and dust discharge airlock two parts.The dust laden air air inlet duct is located at raising middle flask body length direction one side, and exhaust outlet is located on the upper box.

Filter cylinder: with special special-purpose high density stainless steel wire cloth is filtering material, forms with special process is folding, and inside and outside summit is a circular arc, after special the processing, and when preventing that compressed air from jetting clear dirt repeatedly, circular arc position generation fatigue cracking.Being close to filter screen inboard is passive stainless steel lining, and filter cylinder is stainless steel material except that adhesive.

Dust cleaner: control paddle, little gas bag, solenoid electric valve, conduit, adjustable compression air nozzle automatically by the locellus exhausting duct and form.Follow procedure control self-timing carries out blowback to filter cylinder respectively, produces vibration, makes attached to filter screen outer surface dust and is blown off.

The granularity that dust is reclaimed in this pulse dust collector utilization reaches the purpose of separating with screen grid difference, and the characteristics of its maximum are not subjected to the restriction of producer's environment for use and dust characteristic, not only to dry dust, and the recovery that contains the high wet dust of aqueous vapor is not had difficulties.

The specific embodiment

Air-flow spreads rapidly and slows down after dust laden air enters from the external side length direction of deduster raising middle flask air channel 1, and the more massive grit of part fineness ratio just under the effect of gravity, drops down plate along the bottom, air channel voluntarily and slips into dust hopper 12.And fine dust slowly evenly enter with air-flow in space around the filter cylinder 10 in the casing 11, the air behind strainer filtering enters upper box, enters atmosphere by blower fan from exhaust outlet 2.

For keeping filter cylinder 10 air permeability and good, before the clear dirt, 3 moments of the automatic paddle of locellus exhaust outlet close, and filter cylinder stops to filter, by stingy bag 7, solenoid electric valve 6, conduit 5, compressed air adjustable nozzle 4, the dust cleaner that Venturi tube 8 is formed, follow procedure control requires regularly to emit compressed air, and the filter cylinder 10 that is suspended on the card 9 is carried out blowback, makes attached to the dust on the filter screen outer surface and is blown off, fall in the dust hopper 12, and from airlock 13, discharge.

Claims

1.FSQC pulse dust collector is made up of casing, filter cylinder, dust cleaner three parts.Air inlet duct is established in the raising middle flask body length direction outside.After dust laden air entered the air channel, the wind speed diffusion descended, and evenly entered middle casing filter cylinder space all around lentamente, entered upper box after filter cylinder filters, and was carried by blower fan to enter atmosphere.

Filter cylinder: be the Chalk-dust filtering critical piece.Through long-time research, analysis contrast, screening, be filtering material finally with special special-purpose high density stainless steel wire cloth, be folded into filter cylinder.Its feature is a good permeability, is not subjected to the influence of Chalk-dust filtering character.No matter dry dust, wet dust all can be filtered.

Dust cleaner: for guaranteeing the filter cylinder air permeability and good, before the clear dirt, locellus float air channel gate moment closes, filter cylinder is in zero filtration state, by solenoid electric valve self-timing ejection compressed air, filter cylinder is carried out blowback, produce vibration, make attached to filter screen outer surface dust and blown off, fall in the dust hopper, discharge from airlock.

2. the described dust laden air mode of entrance of claim 1 enters towards raising middle flask body length direction air channel along the pulse, and purpose enters middle casing filter cylinder space all around evenly, lentamente for making dust laden air, and is very favourable to filtering.
