DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Field of the Invention The present invention provides a powder delivery tank cars of the powder tank compartment to transport various powder cement powder, fly ash, gypsum powder, silica sand powder was loaded into tank Cree
The present invention relates to a cleaning plant used for cleaning.

2. Description of the Related Art A widely used powder transport tank truck (see FIG. 3) has a structure in which a powder tank 1 in the form of a cylinder is placed laterally on a carrier behind a driver's seat. The partition is divided into an arbitrary number of powder tank chambers 2. Then, each of the powder tank chambers 2 has
For example, an air slide can bus 5 (hereinafter, referred to as a slide can bus 5) is stretched and formed in a squirrel bowl shape so that the zeros can easily gather at the center of the bottom. An air pressure inlet 6 that opens and a delivery hose 10 that exposes the powder pressure feed port 8 from above at the center bottom 7 of the slide can bus 5 are arranged. The air pressure inlet 6 is connected to an air compressor 13 provided on the vehicle body. At the same time, the delivery hose 10 is drawn out of the room through the tank wall and can be connected to the silo 11 side.

When the powder to be loaded and transported is injected from the manhole 3 and stored in the powder tank chamber 2 for transportation, and when the transported powder is transported to the destination silo 11 for wholesale, The delivery hose 10 is connected to the inlet pipe 12 of the silo 11.
After that, compressed air is press-fitted from the air pressure inlet 6 to pressurize the inside of the powder tank chamber 2, and the powder 20 in the room is compressed with the air from the powder pressure port 8 by the pressurizing force by the pressurization. It is sent out and transferred to the silo 11 via the delivery hose 10.

[0004]

The above-mentioned conventional method of transporting powder by a powder transport tank truck and transporting the powder to the silo 11 involves sending the powder 20 in the powder tank chamber 2 to the silo 11 for transport. When the powder is emptied, the powder 20 adheres to the inside of the powder tank chamber 2 (particularly in the corner of the chamber), and the remaining powder adheres to the slide canvas 5. In the case of reloading, it is necessary for a worker who has taken a powder prevention measure such as wearing a mask to enter the powder tank chamber 2 from the manhole 3 and manually clean the residual powder.

However, this manual cleaning operation of the powder tank chamber 2 is restricted in freedom of action in a narrow tank chamber, and in addition, must be performed in a vicious cycle in which the powder is scattered and filled. This is an unfavorable and extremely difficult and time-consuming task. Accordingly, there is a case where the work is easily avoided, and there is a case where it is impossible to transship different kinds of powders. For example, there is a problem that the empty tank runs on the return path to lower the efficiency of powder transportation and increase the transportation cost.

The present invention is directed to cleaning a powder tank chamber of a powder transport vehicle which solves the above-mentioned problems in the prior art.
A cleaning plant to be used is provided.

[0007]

According to the present invention, which solves the above technical problem, a powder hose is pressurized with air, and a delivery hose extending from a powder pressure feed port in the powder tank chamber to the outside of the chamber is used. Cleaning the powder tank room of a powder transport tank cars for pumping transferring the powder of the powder tank room to a silo or the like
