Claims (1)

[Claims for Utility Model Registration] 1. A device for conveying a liquid or a solid mixed with a liquid, which has a suction pipe and a delivery pipe, and has a suction valve that opens during the suction process and a valve that opens during the delivery process. Two sealed tanks, each equipped with a discharge valve, a discharge pump to send pressurized air to the sealed tank, and a suction pump to suck air from the sealed tank are connected via a four-way valve. The suction pump takes in the object to be transported into one sealed tank, and the discharge pump sends out the object to be transported from the other sealed tank, which are alternately performed by switching the four-way valve, thereby transporting the object. In the conveying device that enables the above, a first three-way valve is provided in the flow path connecting the one sealed tank and the four-way valve, and a second three-way valve is provided in the flow path connecting the other sealed tank and the four-way valve. A third three-way valve is connected to the flow path connecting the discharge pump and the four-way valve, and a flow path connecting the discharge port of the suction pump and the third three-way valve is provided, and this flow path is provided with a flow path connecting the discharge port of the suction pump and the third three-way valve. A conveyance device comprising a fourth three-way valve connected to each other, and by switching each of the three-way valves, it is possible to convey an object to be conveyed using either or both of the closed tanks. 2. The conveying device according to claim 1, wherein the first
the first three-way valve and the second three-way valve, respectively.
a two-way valve and a second two-way valve, and the two-way valve has a flow path between the one sealed tank and the four-way valve;
A conveying device connected to each branch pipe connected to the flow path between the other sealed tank and the four-way valve, and capable of opening and closing each branch pipe to the atmosphere. 3 A device for conveying a liquid or a solid mixed with a liquid, in which two sealed tanks, each equipped with a suction valve that opens during the suction process and a discharge valve that opens during the delivery process, share a common suction pipe line. and the air pumps are connected to both sealed tanks through respective four-way valves, and each four-way valve is connected to the suction side and the discharge side of the air pump, By switching the four-way valve, it is possible to select a communication channel between each sealed tank and the suction side of the air pump, or a communication channel between each sealed tank and the discharge side of the air pump, and either or both of the sealed tanks can be selected. A conveyance device that allows the conveyance of objects using one side.
