Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a high-pressure transport device for pneumatically transporting various powder and granular materials at high pressure.

[Conventional technology]

Conventional high-pressure transportation equipment is disclosed in, for example, Japanese Patent Application Laid-Open No. 63-31939.
As seen in the publication, by applying high pressure to a container containing powder and granules (also called a pressurized tank or blow pot), the powder and granules are transported by sending them out to the transport pipe side. .

FIG. 4 is a block diagram illustrating the structure of the conventional high-pressure transport device described above, in which the powder X stored in the supply hopper B is passed through two input valves C and D provided at the discharge port. When a certain amount of air is supplied into container A, injection valves C and D are closed, a compressor (not shown) is activated, and the compressed air is transported from main pipe G to container A through each blow pipe Ga, Gb, and Gc. The granular material X is intermittently plug-transported by being supplied to the inlet portion of the pipe E and the air knife F provided in the middle of the transport pipe E, respectively.

In addition, when the above-mentioned transportation progresses and the amount of granular material The system is such that the above-mentioned transportation is repeated again.

Therefore, with the above-mentioned conventional high-pressure transport device, it is not possible to additionally supply the granular material X during transportation, and when supplying (injecting) the granular material There is a problem that the amount of transportation decreases due to batch transportation, so conventionally, the decrease in the amount of transportation has been compensated for by increasing the transportation capacity of the transportation device to about 1.5 times the required transportation capacity.

[Problem to be solved by the invention]

However, increasing the transportation capacity by 1.5 times requires increasing the size of the transportation pipe E and the capacity of the compressor, which increases equipment costs and running costs, making it unworkable. Is it the economy?
There is a problem that the product life of container A, transport pipe E, etc. will be shortened, and in order to use a large container A and prevent the backflow of powder and granules to 2
Because it is necessary to connect two input valves C and D, the fourth
Since the five dimensions shown in the figure are higher, it cannot be used indoors where sufficient height cannot be obtained, and the entire device becomes taller, which increases the cost of ancillary equipment such as supply hopper B.
There were also issues that affected the price of the entire transportation device.

Therefore, the technical problem of the present invention is to transport powder and granular materials using a continuous M@ transport method instead of batch transport, so that sufficient transport results can be obtained with normal transport capacity, and at the same time, the 5 dimensions can be reduced. The goal is to provide continuous high-pressure transportation equipment that can.

[Means to solve the problem]

The means taken in the present invention to solve the above technical problem are as follows.

(2) A pinch valve with a fitting port is attached to the inlet side of the transport pipe, and the fitting port is configured to be freely connectable to the connection port of the container set in the transport position according to rotation.

(3) On the top side of each of the above containers, there is a supply port that supplies powder and granules toward the input port of the container set in the supply position as it rotates, and a supply port that closes the input port of the container set in the transport position. In addition, a lid with a blow pipe is provided to supply pressurized gas into the container.

(4) An operating arm that connects the fitting port on the transport pipe side by operating it toward the connection port of the container, and an operating arm that operates the cover body with the blow pipe toward the input port of the container to close it. Connect each tip to the same air cylinder so that the connection and closure described above can be performed together.

However, in this case, the term pinch valve refers to a valve body that closes the valve passage and prevents the discharge of powder when it is not pressurized, but when it receives pressure from the supply of pressurized gas, it closes the valve body. It means something that opens to open the valve passage and enable transportation of powder and granules.

[Effect]

The above means works as follows.

■The element mentioned in (1) above makes it possible to continuously transport powder and granules by filling each of a plurality of containers with powder and granules and using the containers in sequence, and also by filling each container with powder and granules, and by filling each container with powder and granules and using the containers in turn. The powder and granules are prevented from being discharged by a pinch valve, so that the filled state can be maintained until it is your turn.

■Element (2) above is a safe system that, when the fitting port on the transport pipe side is connected to the connection port on the container side, pinch valves are installed on both sides of the connection to prevent leakage and backflow of powder and granules. It is possible to form transport routes.

■The element (3) above allows powder and granular material to be supplied through the supply port and input port to the container set in the supply position according to the rotation of the rotary disk, and also set in the transport position according to the rotation of the rotary disk. For other containers that have been used, pressurized gas (
Compressor air) is supplied, so the powder and granules in the containers can be transported under high pressure to the transport pipe by opening each pinch valve. By doing it in a certain rotation,
Enables continuous transportation of powder and granular materials.

The element (4) above is that one air cylinder can simultaneously close the inlet with the lid plate and connect the inlet on the transport pipe side to the connection on the container side. To simplify the mechanism of a part, and to easily set synchronization of closing timing of an input port and timing of an insertion port.

As described above, the above-mentioned technical problem can be solved by the above-mentioned means, and the problems of the conventional technology can be solved.
