Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention is used in the technical field of dust collection, and more particularly to a dust collector having a device for treating dust collected by a filter member.

[Conventional technology]

A dust collector is used for the purpose of cleaning a desired space in a room or collecting dust.

The dust collector has a filter member inside the machine, and the air in the space is sucked by an intake device such as a blower through the filter member, and after the dust is repaired by the filter member, the air not containing the dust is collected. Exhaust to the outside.

The filter member is conventionally disposed at an upper position in the box body of the dust collector in order to remove dust accumulated after long-term use and to restore its function, and at the lower position thereof, an impact or a shock is applied to the filter member. A dust box is provided to receive dust that is removed and drops when vibration is applied. And when the dust in the dust box reaches a predetermined amount,
The dust box is taken out of the machine (outside the box body) to dispose of dust.

[Problems to be solved by the device]

However, in the above-mentioned conventional device, when a large amount of dust is dropped from the filter member and accumulated in the dust box, it rises up when the dust collector is activated and adheres to the filter member again, and The suction performance of the device deteriorates.

Further, when the dust box is taken out of the machine, if it is a large dust collector and the dust box is provided at a high place, the taking out work is troublesome and dangerous. If the filter member is moved together with the dust box so that the dust box can be easily removed, the degree of freedom in designing the dust collector is lost.

It is an object of the present invention to solve the above problems and to provide a dust collecting device in which a dust tank is provided separately from the filter member and the dust box, and the collected dust can be easily treated here. .

[Means for Solving the Problems]

According to the present invention, the object is to provide a dust box for receiving dust falling from the filter member at a position below the filter member for collecting dust in the sucked air in the box body. A dust tank is separately provided at an appropriate position, the dust box and the dust tank are connected by a pipe body, and a screw conveyor for pressure-feeding the dust in the dust box to the dust tank through the pipe body faces the pipe body in the dust box. The outlet of the tubular body facing the dust tank is provided with an elastic valve member that can be opened and closed by being sucked by the suction pressure in the box to seal the outlet and opened by the pressure feeding pressure of the screw conveyor. It is achieved by

[Action]

In the present invention as described above, the filter member is subjected to shock or vibration to be removed at regular intervals or when a predetermined amount of dust is accumulated. The dust falls and is collected in the dust box. In the dust box, the screw conveyor rotates continuously or intermittently, and the dust is sequentially sent under pressure through the pipe body to the dust tank. At the outlet of the tube facing the dust tank, the elastic valve member is adsorbed by the suction pressure inside the box, and the outlet is sealed. However, when the dust in the pipe to be pressure-fed becomes a predetermined amount or more, the suction pressure does not reach the outlet of the pipe, and the elastic valve member is pressed by the pressure of the dust to open the outlet, As a result, the dust is discharged into the dust tank. Thus, the collected dust in the dust tank is disposed of at any time.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a partially cutaway front view of an apparatus according to an embodiment of the present invention, and FIG.
The drawing is a sectional view taken along line II-II of FIG.

The main body 1 of the dust collecting apparatus of the present embodiment is a device P that is a dust collecting target.
Are placed on top of.

The main body 1 of the dust collector is provided with an intake port 3 communicating with the dust collection target device P on the bottom surface of a box body 2, and an exhaust port 4 having a net body or the like on the top surface.

The inside of the box body 2 is divided into an intake chamber A on the intake port 3 side and an exhaust chamber B on the exhaust port 4 side by an inverted L-shaped partition wall 5 in FIG. A relatively large opening 5A is formed on the upper surface of the partition wall 5, and a filter member 6 that covers the opening 5A is provided therein. A blower 7 having a fan 7B rotated by a motor 7A in the exhaust chamber B.
Is arranged so that the air in the intake chamber A passes through the filter member 6 and is sucked into the exhaust chamber B, and is exhausted to the outside of the machine through the exhaust port 4.

The filter member 6 is made of, for example, an air-permeable member made of non-woven fabric, and is supported by a frame body (not shown) around the filter member 6 and attached to the opening 5A portion of the partition wall 5. Immediately below the filter member 6, the lower surface of the filter member 6 is brought into contact with the filter member 6, and shock or vibration is applied to the filter member 6 at an arbitrary time by an external operation to remove dust accumulated in the filter member 6. A member 8 is provided for this purpose.

Further, a cross section is substantially V at a position below the filter member 6.
A dust box 9 having a character shape and having an opening range in the upper part over the entire area of the filter member 6 is provided. The bottom of the dust box 9 is a groove 9A having a substantially semicircular shape, and the screw conveyor 10 is arranged in the groove 9A. The screw conveyor 10 is adapted to bring the dust in the groove 9A to the dust outlet 2A of the box 2 by its rotation.

A dust tank 11 is provided on the floor surface on which the dust collection target device P is installed, and the dust tank 11 is connected to the dust outlet 2A of the box body 2 by a flexible pipe body 12. ing. Further, a plate-like elastic valve member 13 for sealing the outlet is attached to the outlet end of the pipe 12. The elastic valve member 13 is in close contact with the outlet of the tube body 12 by the suction pressure in the box body 2 when the outlet portion of the tube body 12 is in communication with the box body 2, and the inside of the tube body 12 is filled with dust. The suction force is
When it does not reach the 12th outlet, it is opened by the internal pressure of dust.

The operation of the apparatus of this embodiment will be described below.

When dust is continuously collected and a predetermined amount of dust is accumulated on the filter member 6, the dust is blown off by the member 8 and falls into the dust box 9. The dust that has fallen into the dust box 9 is collected in the groove 9A, and is sent to the dust outlet 2A by the screw conveyor 10 here. The dust is further sent to the tube body 12. At that time, when the tube body 12 is not completely filled with dust at the beginning and the outlet of the tube body 12 and the box body 2 communicate with each other by a space, the elastic valve member 13 is caused by the suction force in the box body 2. Seals the outlet to prevent dust from flowing back into the box body 2 (see FIG. 3 (A)). Therefore, the dust is not sent to the dust tank 11, and the amount of the dust in the pipe body 12 gradually increases. As a result, the outlet of the tube 12 and the box 2
, The suction pressure will no longer act on the elastic valve member 13, the elastic valve member 13 will open the outlet due to the internal pressure of the dust sent under pressure by the screw conveyor 10, and the dust will be in the dust tank 11. To the ground (see Fig. 3 (B)).

Thus, when the dust is accumulated in the dust tank 11 by a predetermined amount, the dust is appropriately treated.

[Effect of device]

As described above, according to the present invention, it is possible to treat the dust in the dust tank separately provided below the filter member and apart from the dust box that receives the dust falling from the filter member. The function of the filter member is prevented from deteriorating due to dust rising in the dust box when the dust collector is activated, and the dust tank can be installed at any position, resulting in safety and workability. It is now possible to ensure ease.
