For example, it is made of cloth, reinforced paper, or nonwoven fabric, and has a bottomed bag shape. In some cases, a support member may be disposed inside the support member to prevent unnecessary deformation.

The air introduced into the body 5 through the intake pipe 11 flows from the outside to the inside of the plurality of bag filters 15, and at that time, is contained in the air. The dust that is present is removed from the outer surface of the bag filter 15. That is, if the dust collection operation is continued to some extent, dust adheres to the outer surface of the bag filter 15, and the bag filter 15 becomes "clogged". Therefore, it is necessary to reproduce this regularly.

[0006] The regeneration operation is realized by the following configuration. First, an air tank 21 is provided on the outer side of the body 5 and at the upper end. Three air pipes 23 are connected to the air tank 21. Diaphragm valves 25 are inserted into the three air pipes 23, respectively. Each air pipe 2 above
The secondary side of the third diaphragm valve 25 is branched into two air pipes 27, 27, and these two air pipes 27, 27 extend above the bag filters 15 in two horizontal rows. . Further, nozzles 29 are formed on the lower surfaces of the air pipes 27 and 27 and above the bag filters 15, respectively.

The diaphragm valve 25 is provided with a pilot valve 31. The pilot valve 31 is opened and closed appropriately to supply and discharge air to the diaphragm valve 25, thereby opening and closing the diaphragm valve 25. is there. For example, among the three diaphragm valves 25, only the uppermost diaphragm valve 25 in FIG. 5 is opened, and the other two diaphragm valves 25 are closed. Thus, the upper two rows of bag filters 15 in the figure are in the regeneration operation state, and the lower four rows of bag filters 15 are in the normal dust collection operation state.

In the case of the regeneration operation, the air pipes 27, 27
Compressed air is supplied into each bag filter 15 from above from each nozzle 29. As a result, dust adhering to the outer surface of each bag filter 15 is peeled and dropped outward, thereby regenerating the bag filter 15. At this time, the other bag filters 15 are in a normal dust collection operation state, and air flows upward from below.

A fan 33 is provided on the exhaust body 9, and an electric motor 35 is connected to the fan 33. The fan 33 provides an airflow that goes upward from below. The removed dust falls and accumulates in the hopper 7. The rotary valve 37 attached to the lower end of the hopper 7 is opened appropriately to take out the accumulated dust to the outside.
A filter inspection port 39 is provided on the side of the body 5, and a hopper inspection port 41 is provided on the hopper 7. An opening / closing door 43 is attached to the filter inspection port 39.

[0010]

According to the above conventional configuration, there are the following problems. That is, there is a problem that the maintenance and inspection work of the plurality of bag filters 15 is difficult. That is, when the maintenance and inspection of the bag filter 15 is performed, the opening and closing door 43 is opened and the inspection is performed through the filter inspection port 39. Or go inside and inspect. At that time, depending on the case, the bag filter 15 may be taken out. However, since the plurality of bag filters 15 are extended and arranged in the up-down direction, it is difficult to take out the bag filters 15. Is extremely difficult to remove.

The present invention has been made based on such a point, and an object of the present invention is to provide a dust collector capable of facilitating maintenance and inspection work, particularly maintenance and inspection work of a bag filter. It is in.

[0012]

In order to achieve the above object, a dust collector according to the present invention has one or a plurality of filters disposed in a body to introduce air to be treated into the body, and a filter. To remove the dust contained in the air to be treated on the outer surface side of the filter, while supplying high-pressure air in the filter in a direction opposite to the flow direction of the air to be treated to remove the filter. In the dust collector that removes dust adhering to the outer surface of the dust collector and reproduces the dust, the filter is arranged in a state of being inclined at a predetermined angle, and can be inserted and pulled out from a filter inspection port provided in the body. It is characterized by the following. In this case, it is conceivable to arrange a fan for forming an air flow in the body in an inclined space generated by inclining the filter.

[0013]
