[0002] When separating flammable and explosive materials with a disc separator, in order to ensure safety, nitrogen is introduced into the separator to displace oxygen, and real-time monitoring and interlock protection are carried out through a nitrogen pressure gauge and an oxygen content analyzer to form a nitrogen filling protection system. The liquid-sealed water tank is one of the devices of the nitrogen filling protection system of the disc separator. As Figure 3-4 shown, the pressure inside the equipment cavity is usually determined by the length of the liquid-sealed pipe extending into the liquid level. The existing liquid-sealed water tank has the problem that when the separator starts, the liquid-sealed water splashes everywhere, resulting in water in the workplace, which is not conducive to the maintenance of the workplace. Content of the Utility Model

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A liquid-sealed water tank for a disc separator, comprising a box body, an overflow port, a sewage discharge port, a tail gas outlet and a liquid-sealed pipe;

[0006] Among them, the box body is set as a fully enclosed box body, and a liquid inlet is arranged at the top of the box body;

[0007] The overflow port is arranged at the upper part of one side of the box body, the sewage discharge port is arranged at the lower part of the box body, the tail gas outlet is arranged at the top of the box body, and the liquid-sealed pipe extends into the box body and is located below the liquid level.

[0008] As a further description of the utility model, at least one liquid-sealed pipe is provided.

[0009] As a further description of the utility model, a check valve for preventing the backflow of waste gas is installed on the tail gas outlet.

[0010] As a further description of the utility model, a ball valve for discharging the liquid-sealed water is arranged at the sewage discharge port.

[0011] Compared with the prior art, the technical effect of the utility model is:

[0012] The utility model provides a liquid-sealed water tank for a disc separator, which comprises a box body, an overflow port, a sewage discharge port, a tail gas outlet, a liquid-sealing pipe, a check valve and a ball valve. The box body is set as a fully enclosed box body, and a liquid inlet is arranged at the top of the box body; the overflow port is arranged at the upper part of one side of the box body, the sewage discharge port is arranged at the lower part of the box body, the tail gas outlet is arranged at the top of the box body, and the liquid-sealing pipe extends into the box body and is located below the liquid level. The above-mentioned fully enclosed box body solves the problem that water splashes everywhere due to "bubbling" of the liquid-sealed water during the operation of the separator; the tail gas outlet is connected to a tail gas system to discharge the guided tail gas to the tail gas system, avoiding the accumulation of tail gas in the workplace; a check valve is added to the tail gas outlet to prevent the waste gas in the tail gas system from flowing back, forming nitrogen with a certain pressure in the liquid-sealed water tank, and ensuring the safety in the water tank cavity when the material leaks into the liquid-sealed water tank; the arranged sewage discharge port facilitates the replacement of the liquid-sealed water by opening the ball valve of the sewage discharge port when the liquid-sealed water is turbid and needs to be replaced. The structure is simple and convenient, and the experimental effect feedback is good, improving the safety performance of the disc separator. Description of the Drawings

[0018] The present utility model will be described in detail below with reference to the drawings:

[0019] In an embodiment of the present utility model, a liquid-sealed water tank for a disc separator is disclosed. As Figure 1-2 shown, the liquid-sealed water tank comprises: a box body 1, an overflow port 2, a sewage discharge port 3, a tail gas outlet 4, a liquid-sealing pipe 5, a check valve 6 and a ball valve 7; wherein, the box body 1 is set as a fully enclosed box body, and a liquid inlet 11 is arranged at the top of the box body 1; the overflow port 2 is arranged at the upper part of one side of the box body 1, the sewage discharge port 3 is arranged at the lower part of the box body 1, the tail gas outlet 4 is arranged at the top of the box body 1, and the liquid-sealing pipe 5 extends into the box body 1 and is located below the liquid level.

[0020] Specifically, the above check valve 6 is installed on the tail gas outlet 4. When discharging the nitrogen gas guided by the liquid seal water tank into the tail gas system, it is used to prevent the waste gas in the tail gas system from flowing back into the liquid seal water tank, and the tail gas outlet 4 effectively prevents the accumulation of nitrogen gas in the workplace, thus eliminating potential safety hazards. The above ball valve 7 is installed at the sewage outlet 3 and is used for discharging the liquid seal water when replacing the liquid seal water.

[0021] In this embodiment, at least one but not limited to one of the above liquid seal pipes 5 can be added or reduced according to actual needs.

[0022] Through the above content, the liquid seal water tank of the present utility model is disclosed. Before the separator starts, the liquid seal water tank is filled with water through the liquid inlet 11. During operation, the operation of the separator causes water to flow into the liquid seal water tank and be discharged through the overflow port 2, ensuring the liquid seal height.

[0023] The technical solution of the present utility model has the following advantages compared with the prior art:

[0024] 1. The box body of the present utility model is a fully enclosed box body, which solves the problem of water splashing caused by "bubbling" of the liquid seal water when the separator is running.

[0025] 2. The tail gas outlet of the present utility model is connected to the tail gas system to discharge the guided tail gas into the tail gas system, avoiding the accumulation of tail gas in the workplace.

[0026] 3. A check valve is added to the tail gas outlet of the present utility model to prevent the waste gas in the tail gas system from flowing back, forming nitrogen gas with a certain pressure in the liquid seal water tank, and ensuring the safety in the tank cavity when the material leaks into the liquid seal water tank.

[0027] 4. The sewage outlet provided in the present utility model makes it convenient to replace the liquid seal water by opening the ball valve at the sewage outlet when the liquid seal water becomes turbid and needs to be replaced.

[0028] The above embodiments are only used to illustrate the technical solution of the present utility model and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present utility model shall be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solution of the present utility model.
