Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust discharging device.

[0002]

2. Description of the Related Art Conventionally, an operator has appropriately visually sprayed water so that dust generated from a cupola or the like is not scattered.

[0003]

However, since the amount of dust generated from the cupola or the like is constantly changing, the amount of water varies according to the visual judgment by the operator. Also,
Therefore, continuous unmanned operation was not possible.

Therefore, the present invention solves the above problems,
An object of the present invention is to provide a dust discharging device capable of continuous unmanned operation regardless of changes in the amount of dust generated.

[0005]

In order to achieve the above object, the present invention provides a hopper for receiving powdery dust discharged from a dust collector, a weighing device for measuring the amount of dust inside the hopper, and the weighing device. A dust humidifier for adding a predetermined amount of water to the dust discharged from the hopper by a predetermined amount in response to a signal from the container to form a pellet, wherein the dust humidifier is configured to add moisture to the powder dust. And a water supply means for supplying water to the drum.

[0006] Further, a hopper for receiving the powdery dust discharged from the dust collector, a scale for measuring the amount of dust inside the hopper, and the dust discharged for a predetermined amount from the hopper in response to a signal from the scale. A dust humidifier for adding a predetermined amount of water to form a pellet, and a dust bag for containing pellet dust discharged from the dust humidifier, wherein the dust humidifier is the powder dust. And a water supply means for supplying water to the drum.

Further, a hopper for receiving the powdery dust discharged from the dust collector, a scale for measuring the amount of dust inside the hopper, and the dust discharged for a predetermined amount from the hopper in response to a signal from the scale. A dust humidifier for adding a predetermined amount of water to form a pellet, and the dust humidifier includes a drum for adding water to the powdery dust, and a water supply means for supplying water to the drum. Has,
The drum rotates around an inclined axis.

[0008]

[Function] When the powder dust from the dust collector is received by the hopper and the amount of dust inside reaches a predetermined amount, the dust collector stops the supply of dust by the signal from the weighing instrument, and the hopper feeds the drum of the dust humidifier. Discharge a certain amount of dust.

Next, the water supply means supplies a predetermined amount of water to the inside of the drum in accordance with the amount of dust to add water to the powdery dust. As a result, pellet dust is formed. Further, since the drum rotates around the inclined shaft center, the dust rotates in the vicinity of the lowermost portion of the drum.
Therefore, the dust and the water are well mixed.

The pellet dust is discarded from the drum to the outside, and the dust is stored in the dust bag. When the hopper is empty, dust is newly supplied from the dust collector into the hopper. The above operation is automatically repeated.

[0011]

The present invention will be described in detail below with reference to the drawings showing the embodiments.

FIG. 1 shows an example of a dust discharging device according to the present invention. This dust discharging device adds moisture to powder dust D discharged from dust collector 1 to form pellet dust G. It will be discarded.

Specifically, the dust discharging device is a dust collector 1.
A hopper 2 for receiving the dust D discharged from the hopper 2, a weighing device 3 such as a load cell weighing device provided in the hopper 2, and a (pan type) dust humidifier 5 having a drum 4 are provided.

From the dust collector 1 to the hopper 2 via a feeder 6 such as a screw feeder provided at the bottom of the dust collector 1.
Dust D is supplied inside. A rotary vane type feed valve 15 (rotary valve) is provided between the feeder 6 and the hopper 2.
Is attached.

The dust D in the hopper 2 is discharged to the drum 4 by a discharging device 7 such as a screw feeder.

Numeral 8 is attached to the wall surface of the hopper 2 so that the dust D in the hopper 2 can easily slide down.
It is a vibrator driven by air or the like.

The dust humidifier 5 has a drum 4 for adding water to the powder dust D and a water supply means 20 for supplying water to the drum 4. The drum 4 is rotationally driven by the motor 14. Further, the drum 4 rotates about the inclined axis L. The water supply means 20 includes a water supply passage 9 for supplying water to the inside of the drum 4, and a timer 10 for opening and closing an electromagnetic valve 12 to control the amount of water supplied to the water supply passage 9.

The operating time of the timer 10 (that is, the drum 4
The water supply amount) is set according to the type of dust D.

On the other hand, the measuring device 3 measures the amount of dust in the hopper 2 to reach a predetermined amount of dust in the hopper 2, for example, the hopper 2 is filled with dust D. ─── Conversely, if the amount of dust decreases to a certain amount
For example, when the hopper 2 becomes empty, a drive signal and a stop signal are sent to the timer 10 and the motor 14 of the feeder 6, the discharger 7 and the dust humidifier 5.

An example of the operation procedure of the dust discharging device constructed as described above will be explained.

The powdery dust D generated by the cupola or the like is collected by the dust collector 1 and supplied into the hopper 2 by the feeder 6 and the feed valve 15.

When the hopper 2 is completely filled with dust D, a signal from the load cell meter 3 causes a feed valve.
15 stops and the supply of dust D into the hopper 2 stops. At the same time or immediately thereafter, the ejector 7 is driven to eject a predetermined amount of dust D into the drum 4.

At this time, the dust D is sent into the drum 4, and at the same time, the water supply means 20
The timer 10 is activated to open the solenoid valve 12, water is sprayed into the drum 4 and mixed with the dust D, and the pellet dust G
Becomes

The pellet dust G is discarded from the drum 4 to the dust bag 11 or the like. That is, this dust discharging device is provided with the dust bag 11 that stores the pellet dust G discharged from the dust humidifier 5.

When the hopper 2 is emptied, the discharger 7 is stopped by the signal from the weighing device 3 and the feeder 6 is driven to newly supply the powdery dust D into the hopper 2. The operating procedure of is repeated. In addition, hopper 2
The dust humidifier 5 is stopped and stands by until it becomes full.

As described above, regardless of the change in the amount of dust generated from the cupola or the like, the dust D in the form of powder is mixed with water at a predetermined mixing ratio to be discarded as pellet dust G, which is then scattered by the wind or the like. No pollution can be prevented.

The measuring device 3 may have another structure.

[0028]

Since the present invention is constructed as described above, it has the following great effects.

According to the dust discharging device of the first aspect,
Even if the amount of dust generated from the cupola or the like changes, a predetermined amount of water is automatically added to the predetermined amount of powdery dust D, and it is possible to reliably form a pellet, which enables continuous unmanned operation, Labor saving can be achieved.

Further, since water can be added to the powdery dust D in the drum 4, the structure of the dust humidifier 5 can be simplified and the dust can be made compact.

According to the dust discharge device of claim 2,
It is possible to obtain the same effect as that of the first aspect, and to prevent the pellet-shaped dust G discharged from the drum 4 from being scattered. Then, the pellet-shaped dust G can be disposed of in the dust bag 11 and discarded.

According to the dust discharge device of claim 3,
In addition to achieving the same effect as that of claim 1, it is possible to efficiently add moisture to the powdery dust D in the drum 4, and to minimize the weight (amount of moisture). It can be surely made into a pellet form.
