Description

Warhead type impact air disperser

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air dispersing device for a dust collector, and more particularly, to an warhead-type impact air dispersing device that applies an air dispersing device to a filter structure for a dust collecting device to improve a dust extraction capability of a filter and increase a suction flow rate.

In general, the dust collector is installed in various industrial processes in which a large amount of dust or dust is generated to collect and separate fine dust and contaminants in the air by a filter.

In the dust collector's filter, when dust used in a factory or work site is used for a long time, dust accumulates on the filter cloth or the surface of the filter, which causes a slow flow rate of the filter, an increase in pressure loss, and poor air discharge. There was a problem that the dust collecting function of the filter is poor.

Therefore, the dust collector should remove dust accumulated in the filter to maintain the performance of the dust collector. In the method of removing accumulated dust, a large amount of compressed air is injected into the inside of the filter in a short time by the air injection nozzle to release the dust by applying pressure (jet air) inside the filter.

When the dust collector continuously performs the dust collection function of the filter, a venturi nozzle is installed between the nozzle and the inlet of the filter for efficient exhaustion and delivery of a large amount of compressed air to the filter surface.

Venturi nozzle is a component that increases the flow rate by converting the pressure energy of the air injected from the air injection nozzle into kinetic energy.

Such Venturi nozzles increase the effect of increasing the flow rate of suction of ambient air at a pressure lowered by Bernoulli's law.

Cylindrical cartridge filter has good filtration capability with large filtration area, but it is not easy to shake off dust if it is clogged deep between acid and acid of bent filter material.

Therefore, when the cartridge filter 30 of the conventional cylindrical structure is deeply embedded between the acid and the acid of the filter 30, the viscous and watery dust is bent, the dedusting is not good and the filtration area is reduced to rapidly filter 30 The performance is reduced and this leads to a pressure increase due to the deterioration of the working environment and a drop in productivity.

Referring to the combination process of the blow pipe nozzle 110 and the injection nozzle 120 in order to configure such a dust collector air injection nozzle 100 as follows.

The injection nozzle 120 inserts the injection nozzle bolt 125 into the first hole 124a of the injection nozzle head 122, and when the injection nozzle bolt 125 passes through the first hole 124a, the injection nozzle nut ( 126 is fastened by screwing to fix the spray nozzle bolt 125 to the spray nozzle head 122.

The first inlet hole 113 of the blow pipe nozzle 110 is positioned on the vertical top of the second inlet hole 123 on the upper surface of the injection nozzle head 122, and then the blow pipe nozzle is formed by the fastening bolt 130. 110 is mounted.

When the blow pipe nozzle 110 is mounted on the top surface of the injection nozzle head 122, the head of the injection nozzle bolt 125 causes the gap between the bottom surface of the blow pipe nozzle 110 and the injection nozzle head 122. Of constant air inlet space is formed.

The height of the head of the injection nozzle bolt 125 is adjusted according to the size and thickness to determine the size of the air inlet space between the blow pipe nozzle 110 and the injection nozzle head 122 and according to the size of the air inlet space. It is possible to control the change of air inflow.

Compressed air flows into the through hole 112 of the blow pipe nozzle 110 and descends on the inner circular wall of the air injection pipe 127 of the injection nozzle 120 when injected from the injection nozzle 120.

At this time, a vacuum is generated in the air inflow space between the blow pipe nozzle 110 and the injection nozzle head portion 122 of the injection nozzle 120 to suck the surrounding air.

That is, when compressed air is injected from the first inlet hole 113 of the blow pipe nozzle 110, the injection nozzle 120 is an air inlet space between the blow pipe nozzle 110 and the injection nozzle head 122. As a vacuum is generated in the air around the circular pipe of the blow pipe nozzle 110, the surrounding air is sucked in and the amount of air is greatly amplified (Bernouille effect).

The air jet nozzle 100 for the dust collector is coupled to the blow pipe nozzle 110 and the injection nozzle 120 by the fastening bolt 130, the manufacturing process is simple, the manufacturing cost is low, and does not take much time to install.

Since the blow pipe nozzle 110 and the spray nozzle 120 are manufactured separately, the air spray nozzle 100 for the dust collector is easy to be modified, modified, and maintained.

The injection nozzle 120 of the embodiment of the present invention is coupled to the injection nozzle bolt 125 to the upper surface of the injection nozzle head portion 122, but is not limited to this blow to the configuration that does not combine the injection nozzle bolt 125 It may be coupled to the pipe nozzle 110.

The air jet nozzle 100 and the air dispersing device 200 for the dust collector according to the embodiment of the present invention can be used for all pulse jet dust filters, such as a cylindrical general filter bag, a cartridge filter, a pleated filter bag.

Various types of rectifiers (not shown) may be installed in the injection nozzle 120 to disperse compressed air and to fire.

The rectifier device may be formed in a warhead-shaped cone shape, an acid shape, a flat plate shape, and the like to rapidly accelerate and amplify the flow rate of the inlet air, thereby improving the dust removal performance.

Air dispersing apparatus 200 according to an embodiment of the present invention is made of aluminum, non-ferrous metal, stainless steel, galvanized steel, plastic (including reinforced plastic), is produced by injection molding with aluminum die casting and compressed air from the air injection nozzle When is periodically introduced, it increases the efficiency of dust removal by amplifying the flow of compressed air introduced.

The air dispersing device 200 includes a cone 210 and a lower housing 220.

The cone 210 forms a warhead shape because it is close to the sound velocity of the compressed air introduced from the injection nozzle 120.

The warhead shape enhances the dust removal effect by generating shock waves and downward airflow when compressed air is dispersed.

The cone 210 is a streamlined shape in which the diameter thereof is gradually increased in the downward direction from the pointed upper end portion, that is, in the flow direction of the fluid, such as the bullet or shell warhead form.

Compressed air flowing from the spray nozzle 120 flows on the surface of the cone 210. Air flowing on the surface of the cone 210 inhales air at a high speed around the cone 210 (coanda effect). This coanda effect exhibits a tendency for fluid to cling to or hug close to the surface as it flows through the curved surface.

The flow of air emitted from the injection nozzle 120 is a flow of air flowing along the surface of the cone 210 and thereby aspirates the air around the cone 210 to amplify the flow of incoming air.

The air dispersing apparatus 200 includes a flow of air in which jet air flows emitted from the blow pipe nozzle 110 and the spray nozzle 120 flows along the outer surface from the upper portion of the cone 210 toward the lower portion, and thus is generated. The coanda effect causes the powerful air flow induced around the cone 210 to be fired toward the filter 300, thus acting as an air amplifier.

In other words, the air dispersing device 200 amplifies the flow of inflow air through the flow of air that flows along the outer surface of the cone 210 and the air that inhales the ambient air by several tens or more times by the Coanda effect. More powerful dust removal performance.

The cone 210 has a sharp upper end in the form of bullets and shells so that the jet stream emitted from the injection nozzle 120 can be uniformly sprayed, and the curved surface must be smooth to maximize the Coanda effect. .

The lower housing 220 is attached to the lower surface of the cone 210 is made of a semi-circular curved surface.

The lower housing 220 forms a side flow along the semi-circular curved surface so that the jet air flow passing through the cone 210 does not be directed to the inner center of the filter 300, and is discharged by passing from the upper portion of the filter 300 in the downward direction.

The lower housing 220 is formed in a hemispherical structure to minimize the resistance when the clean air filtered through the filter medium is discharged to the upper portion of the filter 300.

The lower side of the cone 210 protrudes in the form of a wing from the outer edge of the cone 210 to form a dispersion wing 230 formed at least one at regular intervals along the outer edge of the cone 210.

Each of the dispersing wings 230 is inclined in the form of an inclined upper portion and a straight line in which the lower portion is parallel to the outer rim.

The dispersing wing 230 prevents vortex phenomena of compressed air flowing along the outer surface of the cone 210 and prevents shaking of the air dispersing device 200 so that the compressed air flows straight into the filter 300. Induce.

The hook member 240 is made of stainless steel and has a thickness of 3-5 mm and is formed by the number of the dispersing wings 230, and includes a connection part 242, an upper hook 244, and a lower hook 246.

The connection part 242 is formed in a predetermined length in the vertical direction and is bent at least once while changing the direction.

The connecting portion 242 is preferably formed by bending two or more times. The reason for bending the connection portion 242 two or more times is to hold the center of the cone 210 is fixed so as not to shake, and the hook member 240 is the third hole 129 and the dispersing wing ( It serves to easily insert into the hole 232 of the 230.

The upper hook 244 extends from the top of the connection portion 242 is made of a '∩' shape.

The lower hook 246 extends from the bottom of the connecting portion 242 and is formed in a '∪' shape.

Each dispersing wing 230 has a hole 232 is drilled on one side.

The hook member 240 in the longitudinal direction has a lower hook hole 246 penetrating the hole 232 of the dispersing wing portion 230, and an upper hook hole 244 is the third hole 129 of the fastening portion 128. And it is fastened through the fourth hole 129a or one end of the upper surface of the filter 300, so as to be fixed to one of the filter cap 310.

Referring to the process of coupling the air dispersing device 200 to the dust collector air injection nozzle 100 as follows.

Each hook member 240 inserts the lower hook hole 246 into the hole 232 of the dispersing wing portion 230, and then the upper hook hole 244 is inserted into the fourth hole 129a and the third hole 129. When fixed to the air dispersing device 200 and the dust collector air injection nozzle 100 is fastened.

The fourth hole 129a is a hole which is open in one side of the outer edge of the fastening part 128 and is pulled out in the inward direction, and the third hole 129 is an air injection pipe 127 than the position where the fourth hole 129a is formed. It is a hole formed close to the side.

The upper hook tool 244 is inserted into the open portion of the fourth hole 129a in the horizontal direction, and then the other side is fastened through the third hole 129.

The compressed air injected from the first inlet hole 113 of the blow pipe nozzle 110 is combined with the air introduced on the curved surfaces on the left and right sides of the inlet of the injection nozzle head 122 by the Bernoulli effect, thereby amplifying the amount of air.

Compressed air injected from the air injection pipe 127 of the injection nozzle 120 passes through at a speed higher than the speed of sound and generates shock waves and is injected into the cone 210 of the air dispersing device 200.

The air dispersing apparatus 200 sucks air in the air around the cone 210 by the Coanda effect while the compressed air jetted from the air injection pipe 127 descends on the outer curved surface of the cone 210. 300) to the side.

The lower housing 220 of the air dispersing device 200 allows the downward airflow and the impact airflow to diffuse toward the filter 300.

The dispersing wing 230 of the air dispersing device 200 prevents the vortex of the compressed air coming down the outer curved surface of the cone 210 and directs the flow of air to the filter 300 side.
