Description

Description: TECHNICAL FIELD The present invention relates to a dust storage device that stores input dust and appropriately discharges the dust.

(Prior Art) Conventionally, as shown in Japanese Utility Model Application Laid-Open No. 1-83703, dust is introduced into a dust storage tank via a dust chute, and thus the dust storage is performed. There is provided a type in which dust stored in a tank is sequentially discharged from a discharge port by a screw disposed at the bottom of the dust storage device.

(Problems to be Solved by the Invention) However, in the above-described conventional apparatus, it is inevitable that the inside of a dust storage tank for storing dust and the vicinity of an outlet for discharging dust are contaminated by dust and the like. Cleaning in an unsanitary place was a burden on the workers. In particular, since the area around the outlet is exposed to the outside, cleaning is indispensable for sanitary reasons.

(Means for Solving the Problems) A dust storage device according to the present invention is provided with a discharge port on one side of a dust storage tank for storing dust, and a door for opening and closing the discharge port. A screw for discharging dust stored in the dust storage tank through the discharge port is provided at the bottom of the dust storage tank. Further, an input port is provided at the top of the dust storage tank, and a dust chute is connected to the input port. In the refuse storage device that has been provided, a guide device having a bottom portion that is configured to be tiltable is provided around the outside of the discharge port, and an ejection unit that ejects liquid to the guide device is provided. A supply pipe for supplying a liquid to the ejection unit is connected.

In addition, a heat sensor is provided on the upper part of the inner wall of the dust storage tank, and an injection unit for injecting a liquid into the dust storage tank is provided, and a supply pipe for supplying liquid to the injection unit is provided in the injection unit. It is connected via an on-off valve, and when the heat sensor detects heat, the on-off valve is opened and the liquid is ejected from the ejection unit.

(Operation) The dust put into the dust chute is dropped into the dust storage tank via the dust chute and stored in the dust storage tank. Then, by rotating the screw, the dust stored in the dust storage tank is sequentially discharged from the discharge port via the guide device. Then, when the guide device is contaminated with dust or the like due to the discharge of dust, the guide device is washed by injecting a liquid from the ejection unit to the guide device. At this time, the bottom of the guide device is particularly carefully cleaned by tilting the bottom of the guide device and ejecting the liquid while changing the ejection position of the liquid with respect to the guide device.

Further, when a fire occurs in the refuse storage tank, the heat sensor detects the fire and extinguishes the fire by injecting a liquid from an ejection unit. Furthermore, the inside of the dust storage device can be cleaned by injecting the liquid from the injection unit into the dust storage tank.

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

1 and 2 show the configuration of the refuse storage device according to the present invention.

In FIG. 1, reference numeral 1 denotes a dust storage tank for temporarily storing dust input via a dust chute 2 described later.

In the upper part of the garbage storage tank 1, an inlet 3 is formed,
The lower end of the dust chute 2 is provided to extend from the inlet 3 over each floor.

A discharge port 5 is formed on one side (left side in FIG. 2) of the refuse storage tank 1. The discharge port 5 is configured to be openable and closable by opening and closing operations of a door 6.

One end of a turning arm 7 is pivotally supported on each side edge of the door 6, and the other end of the turning arm 7 is fixed to a turning shaft 10 rotatably driven by a drive motor 8. . Further, one end of a guide arm 11 whose other end is pivotally supported above the discharge port 5 of the refuse storage tank 1 is pivotally supported at the upper end edge of the door 6. Thus, by rotating the rotating shaft 10 by the driving motor 8 and rotating the rotating arm 7 up and down, the door 6 opens and closes while being guided by the guide arm 11.

Further, a guide device 20 is provided around the outside of the outlet 5 so as to guide the dust discharged from the outlet 5 so as not to be scattered sideways or downward.

The guide device 20 includes side plates 21, 21 provided on the left and right sides of the discharge port 5, and a lower plate 22 provided below the side plates 21, 21.
The lower plate 22 is configured to be vertically tiltable by the expansion and contraction operation of the cylinder 23.

On the other hand, a screw 12 for discharging the dust stored in the dust storage tank 1 from the discharge port 5 is provided at the bottom of the dust storage tank 1.

A sprocket 1 is attached to one end of the rotating shaft 12a of the screw 12.
3 is fixed, and a sprocket 16 is fixed to the drive shaft 15a of the drive motor 15.
A chain 17 is wound between 13,16. Accordingly, the screw 12 is rotated by the drive of the drive motor 15, and the rotation action conveys the dust in the dust storage tank 1 to the discharge port 5 side and discharges the dust from the discharge port 5 to the outside.

A heat detector 30 is provided above the inner wall of the dust storage tank 1, and an injection unit 31 that sprays a liquid such as water into the dust storage tank 1 is provided. A supply pipe 32 for supplying liquid to the injection unit 31 is connected to the injection unit 31 via an open / close valve (not shown). When the heat sensor 30 detects heat due to a fire in the dust storage tank 1, The on-off valve is opened, and a liquid such as water is injected from the injection unit 31.

The left and right side plates 21, 21 have inner surfaces of these side plates 21, 21,
An ejection unit 35 for ejecting a liquid such as washing water is provided on the inner surface of the lower plate 22 and the discharge port 5. A supply pipe 36 for supplying a liquid such as cleaning water to the injection unit 35 is connected to the injection unit 35.

Next, the operation of the dust storage device thus configured will be described.

First, the dust put into the dust chute 2 from each floor is dropped into the dust storage tank 1 from the inlet 3 through the dust chute 2 and stored in the dust storage tank 1. And
At the time of discharging, the dust stored in the dust storage tank 1 is sequentially discharged from the discharge port 5 by rotating the screw 12, and, for example, a dust collecting vehicle or the like is loaded.

Here, when storing or discharging dust, if a fire occurs in the dust storage tank 1 and the temperature inside the dust storage tank 1 becomes abnormally high, the heat detector 30 detects this. The opening / closing valve is opened, and the liquid is injected from the injection unit 31 into the refuse storage tank 1 to extinguish the fire.

Further, at the time of discharging the garbage, if the guide device 20 is contaminated with garbage, the inner surface of the side plates 21 and 21 is sprayed by ejecting the liquid from the injection unit 35 provided on the side plates 21 and 21. The inner surface of the plate 22 and the outlet 5 are cleaned.

(Effects of the Invention) As described above, according to the present invention, when the guide device is contaminated with dust or the like due to the discharge of dust, the bottom of the guide device is tilted, and the liquid to the guide device is tilted. In particular, the bottom of the dirty guide device can be carefully cleaned by changing the jetting position, thereby improving hygiene and reducing the burden on the operator. In addition, by adjusting the inclination of the bottom of the guide device according to the properties of the dust, it is possible to discharge the dust smoothly.

In addition, when a fire occurs in the trash storage tank, the fire can be extinguished by injecting the liquid from the injection unit provided in the trash storage tank, and the trash storage tank can be insulated by injecting the liquid from the injection unit. The inside can be washed and can be easily cleaned.
