CONSTITUTION:A particulate container 1 receiving a particulate P is inserted in a supply chamber 2 to close said supply chamber 2 by a hermetically closing lid 21. The pressure of the supply chamber 2 is raised by a saving tank 35 until it becomes same to the pressure in a reaction chamber 4a and the particulate container 1 is pressed by a lateral push cylinder 23 to be moved to a predetermined position. An inlet ball valve 5 is opened and the end surface of the particulate container 1 is pressed by a push-incylinder 24 to push the particulate container 1 in the reaction chamber 4a. On the side of a delivery chamber 3, the particulate container 1 can be moved to the delivery chamber 3 from the reaction chamber 4a by the opening and closing operation of an outlet ball valve 5a. By this method, working efficiency can be enhanced.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is particularly applicable to chemical plants, etc., in which materials to be transported such as slurry or powder are supplied as raw materials from storage sections with different internal pressures to other storage sections. The present invention relates to a device for supplying and cutting out objects to be transported and cutting out processed products.

[Conventional technology]

2. Description of the Related Art Screw conveyors, for example, have been conventionally known as devices for supplying and cutting out objects of this kind used in chemical plants and the like. An example of a chemical plant equipped with such a screw conveyor is shown in the third diagram of the schematic diagram.

That is, the reference numeral (4) shown in the figure is a reaction vessel (4) as a high-pressure processing vessel, and this reaction vessel (4) and a low-pressure supply section (2) provided outside of this reaction vessel (4) are connected to each other. Between,
A screw conveyor (+) is provided which transfers the material in the supply section (2) into the reaction container (4) by the rotation of the screw (S), while the reaction container (4) and this reaction container (4) and the low-pressure recovery section (3) provided outside.
The structure includes a screw conveyor (1) that transfers the processed product, which is the object to be transported in the reaction container (4), to the recovery section (3) by rotation of the screw (S). .

Therefore, the object to be transported is transferred from the low pressure section to the high pressure section and vice versa by the rotation of the screw (S) of the screw conveyor (1).

However, when the pressure difference between the transfers is 10 kg/c- or more, and the object to be transported is, for example, a powder or granule material ω), such a screw conveyor (1) transfers the powder or granule material (p). cannot be transported.

In other words, when the pressure difference becomes more than 100 kg/cd, the inner wall of the cylinder of the screw conveyor (1) and the screw (
The pressure inside the reaction container (4) escapes little by little through the small gap that is created when the powder (p) is bitten between S).
This is because it becomes impossible to maintain the pressure inside the reaction vessel (4) at a predetermined pressure.

Therefore, if the pressure difference is 10 kg/c+a or more, the powder (p) between each of the low-pressure supply section (2) and recovery section (3) and the high-pressure reaction vessel (4) is A batch method is applied to the transfer.

More specifically, the powder (p) in the supply section (2) is transferred to the screw condenser (1) into the reaction vessel (4) which has been depressurized in advance.
), and after the transfer is completed, the internal pressure of the reaction vessel (4) is increased.Next, when transferring the rice granules (p) from the reaction vessel (4) to the recovery section (3), the internal pressure of the reaction vessel (4) is increased. The internal pressure is reduced to the same pressure as the recovery section (3).

(Problem to be solved by the invention) However, as mentioned above, the pressure difference is 10 kg/c.
d or more, there is a problem that the powder cannot be continuously transferred from the low pressure section to the high pressure section or from the high pressure section to the low pressure section, and the work efficiency is inevitably reduced. Ta.

Therefore, the present invention provides 10 kg/cm between the high pressure part and the low pressure part.
