Description

[Detailed Description of the Invention] The present invention relates to a collector for cleaning exhaust gas of dust, soot, etc.

BACKGROUND ART Conventionally, a bag filter is known as this type of collector (dust collector) that is generally used to prevent air pollution.

Furthermore, this bag filter requires a very large volume, which limits the installation locations, and also makes maintenance and management troublesome.

In view of the above-mentioned circumstances, the present invention provides a compact collector that can be attached directly to the ventilation duct.

Hereinafter, the present invention will be described with reference to drawings of embodiments.

1 is a ventilation duct that serves as a flue, an exhaust duct, etc. In the middle of the ventilation duct 1, there is an endless belt-like filter cloth 3 stretched over four rollers 2 arranged in the upper, lower, front and rear directions. It is installed perpendicularly.

In this case, among the four rollers 2, two drive rollers 2a at the front and rear of the upper part are rotated by a continuously variable transmission motor 4 via a chain 5, and the two at the front and rear of the lower part have screw grooves 6 on their surfaces. Engraved cleaner/dust feeding roller 2
It becomes as b.

T is a part of a funnel-shaped hopper in which the lower part of the belt-shaped filter cloth 3 protruding below the ventilation duct 1 is housed. A chamber 10 is attached to the lower part of the tip of the screw thread 8 via a valve 9.

Reference numeral 11 denotes a cleaner brush roller that presses against the lower surface of one side 3a of the belt-like filter cloth 3 on the ventilation inflow side.The brush roller 11 is interlocked with the drive roller 2a via a chain 5'. .

Reference numeral 12 denotes a seal piece disposed on both sides of the inlet portion of the ventilation duct 1 which serves as a collection body 13, and a seal roller 14 parallel to the roller 2 is disposed on the upper edge of the seal piece 12.

Reference numeral 15 denotes a spray nozzle facing near the upper end of one side 3a of the ventilation inlet side of the belt-shaped filter cloth 3. The spray nozzle 15 jets out water as necessary depending on the physical properties to be collected and the exhaust temperature to perform wet collection. It is used when.

Further, reference numeral 16 denotes a drain port provided at the upper part of the hopper part I, and the drain port 16 is used when the hopper part 7 is filled with water to make it a wet type.

Next, to explain this effect, first, when collecting dust in the exhaust such as dust and soot, the inlet part 1a in the ventilation duct
The belt-shaped filter cloth 3 arranged like a screen is rotated by the rotation of the driving roller 2a, and the button is pressed.

In this case, the speed of the belt-like filter cloth 3 can be arbitrarily changed by a continuously variable transmission motor 4.

Here, the exhaust gas A flowing into the inlet portion 1a of the ventilation duct 10 directly hits one side 3a of the belt-shaped filter cloth 3, and the dust is caught and collected by the filter cloth 3, and the air is released from the weave 3'. passes.

The exhaust gas A is subjected to a kind of filtering action by the filter cloth 3, and only the filtered exhaust gas flows backward, and further passes through the other side 3a' of the belt-like filter cloth 3, which is the ventilation outflow side, to the outlet portion 1b. It flows.

Of course, this filtering action causes the dust that could not be collected on one side 3a of the filter cloth 3, which is the inflow side, to be collected on the other side 3a' of the second filter cloth 3. The exhaust gas is released as purified air.

In this case, the dust attached to the surface of the belt-like cloth 3 is
Since the brush roller 11 is arranged at the position where it has passed around the four rollers 2 and returned to the inlet side, dust on the surface of the filter cloth 3 is brushed off by the brushing of the brush roller 11.

In addition, the dust adhering to the inner surface 3b of the filter cloth 3 is removed by the unevenness created by the screw grooves 6 because the rollers 2 at the front and rear of the lower part serve as rollers 2b with screw grooves 6. The inner surface is brushed off and the dust that is brushed off inward by the screw groove 6 is carried out to the side end and dropped into the hopper part 7.

Further, the dust on the surface brushed off by the brush roller 11 is also dropped into the hopper part T in the same way.

The dust collected in the hopper part γ in this way is sent to the T end of the hopper part by the screw thread 8 and collected in the chamber 10.

In addition, in wet collection, water is filled up to the brush roller 11 position of part T of the hopper and used as a water tank.

As mentioned above, the collector of the present invention is equipped with a constantly rotating endless belt-like filter cloth in the ventilation duct, a cleaner brush roller on a part of the surface of the filter cloth, and a roller with screw grooves on the inner surface. In addition, by equipping a part of the lower hopper with a screw thread, the dust in the exhaust air is collected with a double filter action to ensure cleanliness, and the filter cloth is equipped with a brush roller and a screw grooved roller. Since the outer cylinder and inner cylinder are constantly cleaned by the machine, there is no chance of clogging.

Furthermore, the square number of the filter cloth can be changed arbitrarily by changing the rotation speed of the filter cloth, and the amount of filter cloth used is small, while positive force loss is small, and replacement during maintenance is extremely short. It can be done in time.

Further, since the structure of the present invention is simplified, it can be constructed compactly and has practical effects such as being able to be used for a long time without causing failure or damage.

In addition, wet use in which water is sprayed onto the top of the filter cloth from a spray nozzle and a part of the hopper is used as a water tank is determined by the physical properties of the material to be collected and the exhaust temperature, but the dust collection action at this time is also carried out as described above. This is substantially the same as the dry collection described in the example.
