Abstract
The utility model discloses a buffer jetting nozzle for dust removal of a dust remover. The buffer jetting nozzle comprises a venture tube, and a filter bag frame ring fixedly arranged on the lower surface of a flanging edge of an air inlet in the top part of the venture tube, wherein the filter bag frame ring is used for fixedly supporting a filter bag, an air outlet in the bottom of the venture tube extends into the filter bag, a plurality of convex blocks are uniformly arranged between the flanging ring of the air inlet of the venture tube and the filter bag frame ring at intervals and an aerial drainage channel is formed between the flanging ring of the air inlet of the venture tube and the filter bag frame ring by the convex blocks so that an airflow buffer outlet is provided for compressed air blown in the filter bag, and when dust removal compressed air is used for strongly blow the filter bag, partial high-pressure airflow can be discharged out of the filter bag through the aerial drainage channel in a ring returning process, and thus direct impaction of the airflow on the filter bag is lightened, the filter bag is protected to some extent, and the service life of the filter is favorably prolonged.
Description
Technical field
The utility model relates to the cleaner technical field, more particularly, relates in particular to a kind of deduster deashing with cushioning the winding-up mouth.
Background technology
At present, traditional deduster is when carrying out deashing to dust filtering bag, usually adopt compressed air by deashing gas flow tube and outspoken the connecing filter bag inside jetting of jetting, rapid bulging filter bag, cause filter bag rapid expanding, contractile motion, remove the dust of filter bag adsorption, thereby reach the purpose of removing the filter bag surface dust.But, because compressed air gas shock to filter bag in deashing process is too strong, the compressed air that blows in filter bag does not have the air-flow buffer outlet, easily cause the filter bag fabric fatigue damaged, grey phenomenon appears leaking, affect the efficiency of dust collection of deduster, and fabric filter bag cost is higher, frequently changing damaged filter bag can increase the production cost that deduster is used enterprise.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of deduster deashing with buffering winding-up mouth, to alleviate the deashing high pressure draught to the direct impact of filter bag, protection filter bag fabric.
For achieving the above object, deduster deashing provided by the utility model is with cushioning the winding-up mouth, comprise Venturi tube and be fixedly mounted on the filter bag frame ring of the air inlet flanging ring lower surface at Venturi tube top, described filter bag frame ring is used for the fixed support filter bag, the gas outlet of Venturi tube bottom is stretched in filter bag, between the air inlet flanging ring and filter bag frame ring of Venturi tube, evenly and be arranged at intervals with several projections, described projection makes and forms a current by pass between the two.
The utility model is by arranging projection between the air inlet flanging ring of Venturi tube and filter bag frame ring; so that be formed with current by pass between the two; for the compressed air that blows in filter bag provides the air-flow buffer outlet; when deashing compressed air carries out the brute force winding-up to filter bag; the part high pressure draught can be discharged filter bag by current by pass in the winding process; thereby alleviated the direct impact of air-flow to filter bag, filter bag has been played certain protective effect, helped to extend the service life of filter bag.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: the 1-Venturi tube; 11-air inlet flanging ring; The 12-gas outlet; 2-filter bag frame ring; The 3-projection; The 4-current by pass; The 5-filter bag.
The specific embodiment
The utility model is described in further detail below in conjunction with the embodiment in accompanying drawing, but do not consist of any restriction of the present utility model.
Consult shown in Figure 1, the utility model deduster deashing is with cushioning the winding-up mouth, comprise Venturi tube 1 and be fixedly mounted on the filter bag frame ring 2 of air inlet flanging ring 11 lower surfaces at Venturi tube 1 top, described filter bag frame ring 2 is used for fixed support filter bag 5, and the gas outlet 12 of Venturi tube 1 bottom is stretched in filter bag 5.
Between the air inlet flanging ring 11 and filter bag frame ring 2 of Venturi tube 1, evenly and be arranged at intervals with several projections 3, normally arrange 3～8, described projection 3 makes and forms a current by pass 4 between the two, for the compressed air that blows in filter bag 5 provides the air-flow buffer outlet.When deashing compressed air carries out the brute force winding-up to filter bag; the part high pressure draught can be discharged filter bag 5 by current by pass 4 in the winding process; thereby alleviated the direct impact of air-flow to filter bag 5, filter bag 5 has been played certain protective effect, helped to extend the service life of filter bag 5.
Described projection 3 can take shape in by the mode of punch ram the lower surface of air inlet flanging ring 11 of Venturi tube 1 or the upper surface of filter bag frame ring 2; also can be fixed in by the mode of welding the lower surface of air inlet flanging ring 11 of Venturi tube 1 or the upper surface of filter bag frame ring 2; certainly can also realize by another way; so long as be formed with current by pass 4 between the air inlet flanging ring 11 at Venturi tube 1 top and filter bag frame ring 2, all fall in the scope of the utility model protection.
Claims (3)
1. a deduster deashing is with cushioning the winding-up mouth, comprise Venturi tube and be fixedly mounted on the filter bag frame ring of the air inlet flanging ring lower surface at Venturi tube top, described filter bag frame ring is used for the fixed support filter bag, the gas outlet of Venturi tube bottom is stretched in filter bag, it is characterized in that: between the air inlet flanging ring and filter bag frame ring of described Venturi tube, evenly and be arranged at intervals with several projections, described projection makes and forms a current by pass between the two.
2. deduster deashing according to claim 1 with buffering winding-up mouth, is characterized in that: the mode of described projection by punch ram takes shape in the lower surface of air inlet flanging ring of Venturi tube or the upper surface of filter bag frame ring.
3. deduster deashing according to claim 1 with buffering winding-up mouth, is characterized in that: the mode of described projection by welding is fixed in the lower surface of air inlet flanging ring of Venturi tube or the upper surface of filter bag frame ring.
