Abstract
The utility model relates to a dust remover for 'c a o' dust, which is also applicable to dust pollution abatement in building materials industry, metallurgical industry, chemical industry and textile industry and the like, belonging to the technical field of the dust-removing device. The utility model is constituted by a static pressure box, a filter box, an aggregating box, an ash discharge valve, a back-flush valve, an exhaust tube, and a fan, which is characterized in that a square-shaped laying bar filter bag is installed in the filter box, one end of the back-flush valve is inserted in a chimney and the other end is inserted in the exhaust tube. The utility model has simple and compact and reasonable structure, and the investment and operation costs are low, the wear of the filter bag and a bracket is eliminated, and the deashing is smooth. The utility model largely increases the service life and the dust-removing effect in the filter bag, and can keep the temperature of air in the filter bag in a state of relative stability, simultaneously improve the working condition of the bag, and be good for healthy. The deashing adopts the manner of natural circulation back-flush, which largely reduces the possibility of condensation of moisture in the dust removers.
Description
Technical field:
The utility model relates to a kind of dedusting at the cao dust, also is applicable to the elimination of dust contamination of building materials, metallurgy, chemical industry, textile industry etc. simultaneously, belongs to the cleaner technical field.
Technical background:
Before the utility model was made, in prior art, sack cleaner normally by plenum chamber, Rose Box, Material collecting box for harvesting, filter bag, blower fan, exhaust column, formed by recoil valve etc.Filter bag is installed in the Rose Box.General skeleton circle or the flat structure of adopting of the filter bag of this deduster.Because the vibration repeatedly during deashing, filter bag face and skeleton easily rub, and cause the filter bag wearing and tearing to be broken, and directly influence its service life.The sack cleaner blowback air of this kind structure natural air that comes from the outside mostly, or the air after the extraneous compression, but the interior high temperature gas flow of extraneous low-temperature airflow and deduster just produces the dewfall phenomenon when meeting.Chemical characteristic according to the cao dust, when cao runs into hydrone, its pH value will reach more than 12, be strong basicity, and the alkali resistance of natural fiber, inorfil and some composite fibre materials that filter bag adopts is very poor, so also cause filter bag corrosion badly broken, reduced the service life of filter bag, when maintenance, the work of maintenance personnel environment is abominable in addition, dust from flying when changing filter bag has had a strong impact on health of operators.
Technology contents:
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of simple, compact and reasonable for structure; Can eliminate the friction of filter bag and support, make deashing more smooth and easy, the possibility of interior dewfall reduces greatly, and can improve the service life of filter bag and the exoskeletal sack cleaner of dust removing effects.
Main solution of the present utility model is achieved in that
It mainly adopts plenum chamber 1 to connect Rose Box 2, Rose Box 2 is connected on the Material collecting box for harvesting 3, ash output valve 4 is installed in Material collecting box for harvesting 3 lower ends, recoil valve 10 is installed on the exhaust column 9, blower fan 6 air inlets connect exhaust column 9, feature is that square filter bag 5 vertically is installed in the Rose Box 2, and recoil tube 8 one ends insert in the chimney 7, and the other end inserts in the exhaust column 9.
Description of drawings:
Fig. 1 is the utility model structural representation:
The specific embodiment:
The utility model adopts plenum chamber 1 connection Rose Box 2, Rose Box 2 to be installed on the Material collecting box for harvesting 3, and square filter bag 5 vertically is installed in the Rose Box 2, in four angles of square filter bag 5 the cloth muscle is housed, and the cloth muscle plays the reinforcement supporting role.In Material collecting box for harvesting 3 lower ends ash output valve 4 is installed, recoil valve 10 is installed on the exhaust column 9, and recoil tube 8 one ends insert in the chimney 7, and its other end inserts in the exhaust column 9, and blower fan 6 air inlets are connected with exhaust column 9, and its air outlet is connected with chimney 7.
Operation principle of the present utility model:
1, the dedusting of dust-contained airflow:
Dust-contained airflow enters plenum chamber 1 on the deduster by air inlet, through the square filter bag 5 in the middle level Rose Box 2, because the effect of blower fan 6 exhausting, the outer surface of filter bag 5 is in negative pressuren zone, and at this moment the larger particles dust in the dust-contained airflow in the filter bag 5 directly falls to Material collecting box for harvesting 3, be adsorbed on filter bag 5 inwalls than fine dust, clean gas is sent to the air inlet of blower fan 6 by filter bag 5 by exhaust column 9, by the air outlet of blower fan 6, is disposed to the external world by chimney 7.
2, the ash discharge of deduster:
The ash discharge of Material collecting box for harvesting 3 is finished by ash output valve 4, and the material feeding mode can adopt conveying worm that the fine dust that reclaims is delivered to the material feeding point.
3, purge mode:
Because the fine dust of filter bag 5 inwalls can be long-pending more thick more, increase filtration resistance, reduce and filter air quantity, filter effect is reduced, therefore must regularly carry out deashing to filter bag 5.Some groups of deashing time-divisions carry out successively, grouping in the deduster is no less than two groups, when one group of deashing, suction opeing is closed in 10 actions of deashing recoil valve, open the recoil mouth, make the pressure of filter bag outer surface, air induce and the effect of the air-flow that recoils under, become malleation by negative pressure, filter bag 5 shrinks, after several seconds, recoil valve 10 moves once again, closes the recoil mouth, open suction opeing, make filter bag 5 outer surfaces recover negative pressure, the filter bag cripling back and forth carries out, shake off to be adsorbed on the dust on the filter bag, reach the purpose of deashing, recoil tube 8 adopts self-heating circulating current organizational form, draws the clean drying and the air of relatively-high temperature from fan outlet, insert insulation in the exhaust column 9, the temperature of the air of guaranteeing to recoil is higher than the dew-point temperature of air in the deduster.
Compared with the prior art the utility model has the following advantages:
The utility model is owing to having improved in the past shape and the structure of filter bag, and is simple, compact and reasonable for structure, Investment and operating cost are low, have eliminated the friction of filter bag and support; Because the support of cloth muscle makes deashing more Smooth and easy, greatly improved service life and the dust removing effects of filter bag; Because adopted the air inward flow filtration-type to flow to, Pure air between outside air and dust air-flow has served as the moisturizing layer, and the gas flow temperature in the filter bag can be protected Hold relatively stablely, improved simultaneously the sanitary conditions of the working environment that changes cloth bag, be conducive to people's health Healthy; Because deashing has adopted Natural Circulation recoil form, and the possibility of deduster dewfall is reduced greatly.
