Description

TECHNICAL FIELD

[0001] The utility model relates to metallurgical technology field, concretely relates to a tank type liquid seal valve. BACKGROUND

[0002] In the field of metallurgical technology, pipe valves are needed to connect different containers, and high-temperature molten metal is transferred through the pipe. Some high-temperature melts (such as lithium) have the characteristics of chemical activity and cannot be directly contacted with air and water vapor. Therefore, the sealing requirement of the equipment for refining such metals is very high. In order to ensure that the pressure, material and liquid level in each container can maintain their own independent state, a valve is needed to complete the absolute sealing of the pipe between the tanks. SUMMARY

[0003] In view of the above problems, the utility model provides a tank type liquid seal valve, which can avoid the poor sealing problem caused by conventional valves, thereby ensuring the purity of the discharged material.

[0004] Specifically, the utility model is implemented as follows:

[0005] A tank type liquid seal valve comprises:

[0006] A sealing tank body is provided with a cooling jacket on the outside, and a cooling channel for cooling fluid to flow is formed between the cooling jacket and the sealing tank body; the lower part of the sealing tank body is provided with a feed inlet, and the upper part is provided with a discharge outlet; there is a height difference between the feed inlet and the discharge outlet, so that the melt is filled in the sealing tank body; the melt filled in the sealing tank body is condensed by the cooling fluid, and the sealing tank body is blocked.

[0007] A heating component is used to melt the solid formed by the condensation of the melt in the sealing tank body, so as to realize the unsealing of the sealing tank body.

[0008] Further, the tank type liquid seal valve further comprises:

[0009] A cold vortex pipe is connected with the cooling channel through a cold air port, and is used to send cold air into the cooling channel to cool the melt in the sealing tank body. The cold vortex pipe is composed of a nozzle, a vortex chamber, a separation hole plate, a cold air port and a hot air port. When working, the compressed gas expands in the nozzle, and then enters the vortex chamber in a tangent direction at a very high speed. When the gas flow rotates at a high speed in the cold vortex pipe, it is separated into two gas flows with different total temperatures after vortex transformation, and the hot air is discharged, and the cold air is sent into the cooling channel to cool the melt in the sealing tank body.

[0010] Further, the cold vortex pipe is connected with the lower part of the cooling channel, and the upper part of the cooling channel is provided with an exhaust port, so that the cold air flows from bottom to top.

[0011] Further, the heating component is a heating electric furnace, which is located at the bottom of the sealed tank body, and is used for realizing unsealing of the sealed tank body.

[0012] The working principle of the utility model is as follows:

[0013] In the open state of the liquid seal valve, the melt fills the sealed tank body first, and after filling to the height of the discharge port, the melt enters the downstream equipment from the discharge port; when it is needed to close the liquid seal valve, the cold vortex pipe passes compressed air, and the cold air outlet discharges cold air, which enters the cooling channel between the sealed tank body and the cooling jacket, and cools the melt in the tank, and after the melt is condensed into solid, the blocking of the melt is realized.

[0014] Compared with the prior art, the utility model has the beneficial effects that:

[0015] (1) The utility model realizes the solid-liquid state conversion of the material in the sealed tank body through the cold vortex pipe and the heating component, and further controls the opening and closing of the valve.

[0016] (2) Since the valve realizes the sealing of the pipeline through the different solid-liquid states of the material, there is no mechanical wear and tear, and the service life is long. BRIEF DESCRIPTION OF DRAWINGS
