Abstract

PURPOSE:To do away with blowback from a storage container by providing an air inlet for operation of a piston at one end of a cylinder and an intake at the side face of a tank so as to connect the passage of a high pressure gas to the air inlet through a three way solenoid valve and its branch passage to the intake. CONSTITUTION:At a high pressure gas storage device 28, a cylinder 2 and a gas intake 1a are provided and at one end of the cylinder 2, an air charging/ discharging port 12a and at the other end, an exhaust port 12a and within the cylinder, a piston 3 are provided. A gas flows from a compressor 22 to the discharging port 12a through a three way solenoid valve 21 and a passage 24 and flows to an intake 1a through a branch passage 25. Therefore, a gas inside the cylinder and a gas inside a tank come to be different substances and it is made possible to do away with blowback from a storage container.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a rapid discharge device for high-pressure gas,
In particular, the present invention relates to a high-pressure gas rapid discharge device for facilitating the flow of particulate material, particularly powder or granular material, from a storage container.

(Prior art) As a conventional technology of this kind, for example, Japanese Patent Publication No. 56-37924
There is a ventilation system shown in Figures 2 (a) and (b) described in the issue. FIG. 2(,) is a sectional view of a conventional ventilation device, and FIG. 2(b) is an explanatory diagram of how to use the ventilation device of FIG. 2(,).

As shown in Figure 2 (,), the conventional ventilation system
1, a cylinder 32 provided in the tank 31 and having an open end 32-1 and a closed end 32-2, a piston 33 slidably provided in the cylinder 32, and a cylinder 33 that penetrates the tank 31 and has an open end 32-1 and a closed end 32-2. 33 extending to the closed end 3 of the cylinder 32
The air supply hole 36 of the pressure introduction means for introducing pressure between the piston 2-2 and the piston 33, and the open end 34-1 of one inner end thereof, which is provided through the tank 31, are inserted into the storage container 35. It is composed of a pipe 34 which is designed to provide pressure, and a relatively small hole 37 which is provided through the wall of the cylinder 32 and is closed by the piston 33. The pressure introduced into the cylinder 32 from the air hole 36 moves it toward the open end 32 - 1 of the cylinder 32 , sealingly engages the open end 34 - 2 of the other inner end of the pipe 34 and closes the small hole 37 . This is a ventilation device that promotes the outflow of particulate matter by opening the tank 3 and introducing pressure into the tank 3. As shown in FIG. 2(b), this ventilation device is arranged at
4-3, it is attached to the storage container 35. Note that the symbols given in FIGS. 2(,) and (b) are used throughout this specification for convenience of explanation, and are different from the symbols in the original publication. The same applies below.

Another conventional example is the ventilation device shown in FIG. 3, which is described in Japanese Patent Publication No. 56-48001.

FIG. 3 is a front view with main parts cut away. Another example of this conventional ventilation system is that the conventional ventilation device shown in Figure 2 (,) is fixed to a storage container such as a silo by welding, so if the storage container is large, it requires installation at multiple locations. In order to improve the cost, the tank 41 that constitutes the high pressure air supply device
and a cylinder 42 with a valve mechanism that fills the tank 41 with high-pressure air and delivers the filled air to a container such as a silo.
, a ventilation device 48 including a piston 43, an exhaust pipe 44, etc. is separated, and only the ventilation device 48 is fixed to a storage container 45 such as a silo, and the tank 41 is detachably attached to this ventilation device 48, so that the tank 41 can be attached to and removed from the ventilation device 48 at desired locations. 41, high pressure air can be supplied.

(Problems to be Solved by the Invention) As a conventional technique, the ventilation device shown in FIGS. High-pressure air is introduced into the cylinder 32, and the movement of the piston 33 causes the tank 3 to
Since high-pressure air is introduced into the interior of the storage container 35 such as a silo through the i4 eve 34, dust, oil, and moisture in the high-pressure air and powder particles that are blown back from the storage container 35 such as a silo are removed. There is a drawback that objects and the like get stuck between the piston 33 and the small hole 37, or accumulate inside the tank 31, resulting in a decrease in ventilation efficiency when used for a long time. In addition, each part of this device is connected using welding, so cleaning
Another drawback is that it is not easy to disassemble and reassemble for inspection.

This device of the other prior art shown in FIG. There were drawbacks that impaired retention.

In addition, since compressed air flows from the supply source through the small hole 49 of the piston 43 in the axial direction, it takes time to fill the air, which is inconvenient for repeated use in a short period of time. Although this method speeds up the opening of the piston 43, it also has the disadvantage that a large amount of high-pressure air in the tank 41 is wasted and the opening of the piston 43 is delayed.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a cylinder having a piston mechanism for storing and rapidly discharging high-speed gas, penetrating a part of the high-speed gas storage tank. , an air supply hole for piston operation is provided on one end surface of the cylinder, and a tank gas installation port is provided on the wall surface of the other portion of the storage tank, so that the flow path for high-speed gas from the compressor is connected to a three-way electromagnetic It was connected to an air supply hole for piston operation via a valve, and a branch flow path from the three-way solenoid valve was connected to a tank gas attachment port via a check valve.

(Function) As mentioned above, the air supply hole for piston operation is located on the end face of the cylinder.
Tank gas installation ports were provided on the walls of other parts, and the former was connected to the flow path from the three-way solenoid valve, and the latter was connected to the branch flow path of the flow path from the three-way solenoid valve via a reverse valve. Therefore, the gas for piston operation in the cylinder and the gas in the tank are separated, and the piston operation, storage of high-pressure gas in the tank, and high-speed discharge are performed by separate gases.
