Industrial application field The present invention is characterized in that the main body of the dust collector is divided into a filtration chamber and a purified air chamber vertically by a partition wall, and both chambers are connected to a large number of inlets bored in the partition wall. The air nozzles are connected to each other through a suspended filter bag fitted with an opening, and each inlet is provided with an air nozzle having an injection port for injecting high-pressure gas into the bag in order to blow off dust attached to the outer surface of the filter bag. This invention relates to improvements to bag dust collectors.

Regarding nozzles, there is a type with a diffusion device installed below the nozzle (Special Publication No. 51-3943).
Alternatively, a secondary pipe component with a sub-discharge port at the tip is attached to a pipe component with a main discharge port at the tip, and the high-pressure air jetted from the sub-discharge port creates an air shield and purifies the air.

It can easily become clogged. And in that case,
Even if high-pressure air is blown toward the center of the filter bag, the pressure of the air against the inner circumferential surface of the filter bag is weak, and therefore the ability to blow off dust is extremely poor. In addition, those equipped with a diffusion device below the nozzle can spray the inner circumferential surface of the filter bag to some extent, but the spraying force is weakened due to the diffusion, and there is still a limit to the dust removal ability. On the other hand, regarding devices that create an air shield by providing a sub-discharge port to prevent purified air from getting mixed in, there is a technique for installing the sub-discharge port at an angle, but that is only for creating an air barrier. Since the filter bag is not designed to blow away dust, it is not possible to evenly spray high-pressure gas onto the inner peripheral surface of the filter bag.

Means for Solving the Problems The present invention improves the dust collection ability by forming the filter bag with a W-shaped cross section, so that high-pressure air is not concentrated in one place and is sprayed uniformly and evenly onto the inner circumferential side of the filter bag. By being
It also aims to improve the dust removal efficiency, and its configuration is such that the filter bag is drawn in with the closed end end turned inward, and has a W-shaped cross section, and the air nozzle is arranged on the center line of the filter bag. In addition, a plurality of injection ports facing diagonally outward are provided at the tip of the air nozzle.

Embodiment The drawing shows a bag dust collector according to the present invention, in which the inside of the main body 1 of the dust collector is divided vertically into a filtration chamber 3 and a purified air chamber 4 by a partition wall 2. A large number of suction ports 5, 5... are provided.
In the filtration chamber 3, filter bags 6, 6, . A hopper 7 for collecting dust is formed below the filtration chamber 3, and a dust-containing gas inlet 8 is provided on the side thereof. On the other hand, inside the purified air chamber 4, there is an air pressure feeding pipe 9 connected to a compressor (not shown).
The air nozzles 10, 10, . . . are disposed so as to cross directly above the suction ports 5, 5, .
is installed. Further, an exhaust duct 11 is provided on the side of the purified air chamber 4. The air nozzle 10 has four injection ports 1 at its tip as shown in the third figure.
0a, 10a... are provided diagonally outward. As a result, high-pressure air is diffused from the injection port 10a in a conical shape and is uniformly injected over the entire inner peripheral surface of the filter bag. Filter bag 6 is
By inverting the end of the closed part inward and drawing it in, and by supporting the end 6a through the support fitting 12 at the center near the opening, the overall cross section is made W-shaped and the surface area is expanded. There is. According to the dust collector configured in this way, when the dust-containing gas is sent from the dust-containing gas inlet 8, the dust-containing gas flows into the filter chamber 3.
Inside each filter bag 6 is passed from the outer surface to the inner surface, during which fine solids are separated as dust. The air then passes through the suction port 5 and enters the purified air chamber 4, where it is sucked in by a blower or the like and discharged as clean air from the exhaust duct 11.
When dust adheres to the outer surface of the filter bag 6, reducing the dust collection ability or causing clogging, high-pressure air is appropriately jetted from the air nozzle 10 to blow it off by the jetting pressure. The dust that has been brushed off falls into the hopper 7 by the action of the air flow from the air nozzle 10 and its own weight, and the dust that has fallen into the hopper 7 and settled is discharged by appropriate means.

れもない。 The high-pressure air injected from the air nozzle 10 is diffused in a conical shape and is sprayed, so it is not concentrated on the retracting tip 6a of the filter bag 6, but is evenly sprayed on the inner circumferential side of the filter bag, which improves the blowing efficiency. In addition, there is no risk of the support fitting being exposed to the injection pressure and causing trouble to the support part.

Furthermore, although the filter bag has been illustrated as having a W-shaped cross section, the effect of improving dust removal efficiency can be similarly exhibited even if the filter bag has a general cylindrical shape with the lower end closed.

その実益は多大である。Effects According to the present invention, since the filter bag is formed to have a W-shaped cross section, the dust collection ability is improved. Also,
Since the high-pressure air is diffused and sprayed in a conical shape, a strong and uniform spraying pressure is obtained against the inner surface of the filter bag, and uneven dusting does not occur, so that the original dust collection ability can be restored. Furthermore, there is no possibility that the spraying pressure may be too strong in some areas, causing trouble at the filter bag attachment part, etc. As described above, it is possible to improve the dust collection capacity and the durability of the dust collection device and prevent a decrease in the dust collection capacity.
The benefits are enormous.
