Abstract

A bag type dust remover for mechanical dust cleaning comprises a lower box body, a main box body, a tubesheet, cloth bags and a suspension which can move up and down. The dust remover is characterized in that a push-pull rod, a junction plate and upper and lower limited blocks are designed, wherein the push-pull rod is provided with a telescopic link which can rapidly extend and retract; one end of the junction plate is fixed and the other end thereof can break away and be contacted, and the junction plate is used for directly connecting the telescopic link and the suspension; and the upper and lower limited blocks are positioned on the inner wall of the main box body, respectively have at least three points forming a group and limit the upper and lower movement ranges of the suspension. The telescopic link acts for the first time so that the cloth bags and the suspension fall freely and then are blocked by the limited blocks so that the velocity jumps to zero and the acceleration is about 20m/s2. During the second action, the telescopic link suddenly hits the still suspension in the process of rapid movement and drives the suspension to move up and then suddenly stop, twice velocity jumps exist in about 0.1s and the acceleration is more than 300m/s2. The dust is cleaned three times through once extension and retraction, and the dust breaks away from the filter materials in the upper and lower directions without affecting the cloth bags around, thus the dust cleaning effect is better than that of pulse.

Description

Bag type dust remover for mechanical dust cleaning

Technical field

The present invention relates to a kind of deduster, relate in particular to a kind of bag type dust remover for mechanical dust cleaning.

Background technology

Existing sack cleaner is divided three classes by purge mode, and the one, mechanical oscillation rapping class, the 2nd, with blower fan back suction blowback class, the 3rd, with compressed-air actuated pulse class; Though first kind structure is simple but ash-removal effect is poor; The second class effect is general; Though the 3rd class effect is best, pulse valve and winding-up pipe because of One's name is legion is arranged are flushed to the first-class defective of adjacent cloth bag to dust when having easy break-down, deashing.

The objective of the invention is to design a kind of ash-removal effect and pulsion phase with, can overcome a kind of sack cleaner of defect pulse with mechanical ash removing.

Summary of the invention

The present invention is that the technical scheme of being taked that achieves the above object is: the sack cleaner that is provided, comprise lower box, main box, card between lower box and main box, many cloth bags of the last end closure that the lower ending opening that is positioned at main box and card hole communicate and link, design has the hanger movable up and down that is used to hang many cloth bags that is positioned at the main box internal upper part, be positioned at the main box top and go up the pull bar that outside its expansion link that connects firmly with main box can stretch out fast and shrink, end between expansion link and the hanger fixedly other end can break away from and being used to of can contacting is connected the connecting plate that is connected indirectly between expansion link and the hanger, is positioned to form the lower position block of one group the up and down scope of restriction hanger by at least three points on the main box inwall.

Connecting plate was the bar shaped connecting plate when expansion link was flexible downwards, be positioned at the connecting bolt of bar shaped connecting plate and expansion link junction, the bar shaped connecting plate is passed down through that lower, transverse behind the hanger and bar shaped connecting plate connect firmly can hold hanger and the cross bar of pull-up, and expansion link stretches out the back downwards and breaks away from hanger and at regular intervals with hanger with the cross bar that the bar shaped connecting plate connects firmly.

Design is fast by being positioned at the move upward upper limit of distance of the restriction hanger that has at least three points to form a group on the main box inwall.

For expansion link being stretched out fast and shrinking, pull bar is designed to cylinder.

For realizing automatic ash removing, design has circuit control system and switch board.

Expansion link is divided into upwards flexible or flexible downwards, and one is selected in two kinds of designs.

The upper side frame through the main box top board reaches the main box exterior upper portion that design had boundary frame area to connect firmly with hanger in main box when expansion link was upwards flexible is positioned at and breaks away from also shaped as frame connecting plate at regular intervals fully directly over the expansion link when shrinking with expansion link.

Deashing principle, advantage and good effect: the expansion link when pull bar is flexible downwards stretches out downwards suddenly fast, hanger is out of hand, just fall with the movement of falling object, the prominent chance stopping of lower position block in dropping process, the velocity jump of hanger is zero, be attached to the dust on the cloth bag inner surface owing to exist inertia just to hightail the cloth bag free-falling, dust is eliminated; At this moment since the downward release length of pull bar greater than the distance between upper limit position block and the lower position block, so the bar shaped connecting plate stretches out certain distance downwards more; Expansion link is oppositely gone up fast and is regained then, in expansion link makes progress the process of rapid movement, clash into hanger suddenly and drive hanger and move upward fast by the cross bar on the bar shaped connecting plate, this is again a velocity jump, and has bigger acceleration, carries out the deashing second time; Hanger continues to be moved upward by the expansion link drive, and when moving to upper limit position block, owing to stopping of upper limit position block, the speed of hanger sports zero again, and this is the sudden change of speed for the third time, carries out deashing for the third time; Both expansion link reciprocating action once then had the sudden change of three speed, carried out deashing three times.And pulse action once only carries out identical with this programme substantially deashing of intensity, and after dust breaks away from cloth bag with horizontal direction to around motion, be easy to but by around cloth bag adsorbed; Three deashings of this programme, the direction of its acceleration all vertically upward or downwards, adjacent cloth bag around dust does not influence is so ash-removal effect is better than pulse.

Deashing principle when expansion link is upwards flexible is with flexible identical downwards, and the direction of motion is also identical, and another kind of scheme was to shrink when difference was that a kind of scheme is stretched out.
