CN202169118U - Pulse jetting device of bag filter - Google Patents

Abstract

The utility model provides a pulse jetting device of a bag filter. A jetting bent pipe in the prior jetting system of the bag filter adopts a standard elbow and is manufactured by adopting a welding manner, so that the jetting airflow is unsmooth, resistance is formed, air quantity loss is produced, and the dismounting and the mounting are inconvenient. The pulse jetting device comprises a jetting bent pipe and a jetting pipe connected with each other, and is characterized in that the bending diameter of the jetting bent pipe is at least three times of the pipe diameter of the jetting bent pipe. By increasing the bending diameter of the jetting bent pipe, the jetting resistance of compressed air and the required pressure value of the compressed air can be conveniently reduced, and the jetting pressure of the pulse jetting device is lower than the traditional jetting pressure by 0.2 to 0.3MPa. The pulse jetting device has the advantages that the resistance of the pulse jetting airflow can be effectively reduced and the jetting air quantity loss can be decreased; and meanwhile, the jetting bent pipe can be conveniently connected with the jetting pipe in an inserted manner, the positioning is accurate, mass rapid mounting and dismounting of the jetting pipe is realized, and the dismounting and mounting efficiency of the jetting pipe is obviously improved.

Description

A kind of pulse spraying equipment of sack cleaner

Technical field

The utility model belongs to sack cleaner, specifically is the pulse spraying equipment that uses in a kind of sack cleaner.

Background technology

At present, the winding-up bend pipe adopts the standard type elbow in the sack cleaner injection system commonly used both at home and abroad, and the bending radius of elbow is little; Be the twice of elbow caliber at most, and this type winding-up bend pipe adopts welding manner to process, the winding-up bend pipe distortion after the welding greatly; There are the many welding slags that can't clear up; Not smooth at the inner-walls of duct air-flow that causes easily jetting, form resistance, produce the tolerance loss; In addition, the winding-up bend pipe adopts flange to be connected with bolt with the winding-up pipe, and the mounting or dismounting trouble is time-consuming, gets rusty if any bolt, is difficult to pull down, even needs to adopt the flame cutting, easily damage is caused in the installation position.

The utility model content

The utility model provides a kind of pulse spraying equipment of sack cleaner to the defective that prior art exists, and jet smoothness and can effectively reduce tolerance consumption can also improve the dismounting efficient of winding-up pipe.

For this reason, the utility model is taked following technical scheme: a kind of pulse spraying equipment of sack cleaner, comprise interconnective winding-up bend pipe and winding-up pipe, and it is characterized in that the bending diameter of said winding-up bend pipe is three times in the caliber of said winding-up bend pipe at least.The bending diameter that increases the winding-up bend pipe helps reducing compressed-air actuated winding-up resistance and to the compressed-air actuated force value that requires, hangs down 0.2～0.3MPa than traditional jetting pressure.And satisfy the deashing requirement, reduce air consumption, reduce the air compression station load, electricity saving and energy saving; Alleviated the winding-up friction of air greatly, prolonged the service life of filter bag filter bag.

Described winding-up bend pipe is pegged graft to overlap through one with the winding-up pipe and is joined, and an end of said grafting cover welds with the winding-up pipe, and the other end is connected with winding-up bend pipe gap.Accurate positioning, dismounting efficient obviously improves.

The top of said winding-up bend pipe is connected with branch gas tank assembly and electromagnetic impulse valve, is convenient to the aeration quantity size is controlled.

Blowing device comprises the winding-up bend pipe and winding-up pipe that many groups are parallel to each other, and the middle part and the end of said each winding-up pipe are fixed through fixed mount and ready-package pressing plate respectively.Based on sack cleaner winding-up quantity, filter chamber's size, form n row blowing device, firmly and be convenient to dismounting in batch fast through the fixing winding-up pipe of fixed mount and ready-package pressing plate location.

The utility model can effectively reduce the resistance of pulse jet air-flow, reduces the loss of winding-up tolerance; Simultaneously, the winding-up bend pipe is convenient with the grafting of winding-up pipe, and accurate positioning has realized the loading and unloading fast in batch of winding-up pipe, and the pipe efficiency of loading and unloading of jetting obviously improves.

The specific embodiment

The pulse spraying equipment of sack cleaner as shown in Figure 1 based on winding-up quantity and filter chamber's size of sack cleaner, is formed many row's blowing devices.Blowing device mainly is made up of winding-up bend pipe 3 and winding-up pipe 5; The top of winding-up bend pipe 3 is connected with branch gas tank assembly 2 and electromagnetic impulse valve 1; The winding-up bend pipe adopts Special Equipment integral body to process; Evenly have a plurality of nozzles 8 on the winding-up pipe 5, the bending diameter of winding-up bend pipe 3 is three times in the caliber of winding-up bend pipe 3 at least.Winding-up bend pipe 3 joins through a grafting cover 4 with winding-up pipe 5, an end of this cover 4 of pegging graft and pipe 5 welding of jetting, and the other end is connected with winding-up bend pipe 3 gaps.The middle part of many group winding-up pipes 5 and end are fixing with ready-package pressing plate 7 through fixed mount 6 respectively.

What need particularly point out is; The mode of the foregoing description only limits to describe embodiment; But the utility model is confined to aforesaid way incessantly; And those skilled in the art can modify in the scope that does not break away from the utility model in view of the above easily, so the scope of the utility model should comprise the principle that the utility model discloses and the maximum magnitude of new feature.
