Referring to fig. 1 and 2, an embodiment of the present application provides a sealing device for a mixing chamber cover plate of a DRT-based extraction tank, which includes a cover plate 10, a water seal 30, and a water replenishing mechanism 40.

The cover plate 10 has a first surface 10a and a second surface 10b opposite to each other, the first surface 10a is used for covering the mixing chamber of the extraction tank, and the second surface 10b is surrounded with a water seal tank 20 for placing liquid. The water seal 30 is disposed on one side of the second surface 10b, a cavity through which the stirring shaft passes is formed inside the water seal 30, and one end of the water seal 30 facing the second surface 10b is inserted into the water seal tank 20, so that the cavity forms a closed state. The water replenishing mechanism 40 comprises a water replenishing tank 41 and at least one group of water inlet components, the water inlet components comprise a water inlet pipe 421, a plug 422 and a limiting piece 423 with a limiting cavity 423a, the limiting piece 423 is arranged in the water sealing groove 20, a through hole a for communicating the limiting cavity 423a with the water sealing groove 20 is formed in the side wall of the limiting piece 423, one end of the water inlet pipe 421 is communicated with the water replenishing tank 41, the other end of the water inlet pipe 421 extends into the limiting cavity 423a, and the plug 422 is arranged in the limiting cavity 423a so that the plug 422 controls the on-off of the water inlet pipe 421 according to the liquid level in the water sealing groove 20.

Illustratively, the cover plate 10 is used to cover the mixing chamber of the extraction tank so that the mixing chamber is closed. For this purpose, in the present embodiment, the first surface 10a and the second surface 10b of the cover plate 10 are used as references of the extraction box, namely: the side for covering the mixing chamber of the extraction tank is the first surface 10a and the side facing away from the mixing chamber is the second surface 10b.

For example, at present, the stirrer is disposed in the extraction tank, and the top of the cover plate 10 is provided with an opening to enable the stirring shaft to pass through, and since the stirring shaft is a continuous rotating component, a gap is often left between the opening and the stirring shaft, which is difficult to completely seal, and organic gas in the mixing chamber is easy to escape, thus causing environmental pollution. For this reason, in the embodiment, the water seal groove 20 is formed on the second surface 10b of the cover plate 10, then a water seal member 30 having a cavity is disposed on one side of the second surface 10b, and one end of the water seal member 30 facing the second surface 10b is inserted into the water seal groove 20, and the cavity is sealed by the liquid in the water seal groove 20, so that the organic gas escaping from the gap enters the cavity, and finally the liquid in the water seal groove 20 absorbs the organic gas, thereby effectively avoiding the air pollution caused by the escape of the organic gas.

The liquid may be water or a solution that absorbs organic gas exclusively, and is not limited thereto.

According to the sealing device of the mixing chamber cover plate 10 of the extraction tank based on the DRT, the limiting piece 423 with the limiting cavity 423a is arranged in the water sealing tank 20, the plug 422 is arranged in the limiting cavity 423a, then one end of the water inlet pipe 421 extends into the limiting cavity 423a, the other end of the water inlet pipe 421 is connected with the water supplementing tank 41, the limiting cavity 423a is communicated with the water sealing tank 20 through the through hole a so that the liquid level in the limiting cavity 423a is the same as the liquid level in the water sealing tank 20, when the liquid level in the water sealing tank 20 is higher, the buoyancy received by the plug 422 in the limiting cavity 423a is larger, so that the plug 422 is close to the end part of the water inlet pipe 421 extending into the limiting cavity 423a and is abutted against the end part of the water sealing tank 423a to seal the end part, and the liquid in the water supplementing tank 41 stops automatically supplementing the liquid into the water sealing tank 20; when the liquid level in the water seal tank 20 is low, the plug 422 is subjected to small buoyancy and moves downwards so that the water inlet pipe 421 is conducted to inject liquid, thereby realizing the automatic liquid supplementing in the water seal tank 20, effectively reducing the labor cost and the operation safety risk caused by the traditional manual liquid supplementing, and simultaneously effectively reducing the risk of escaping organic gas caused by untimely liquid supplementing.

In one embodiment, the limiting member 423 includes a first limiting plate 4231 and a second limiting plate 4232 both disposed in the water seal groove 20, a limiting cavity 423a is defined between the first limiting plate 4231 and the second limiting plate 4232, and a through hole a is formed in the lower portions of the first limiting plate 4231 and the second limiting plate 4232.

In one embodiment, the ends of the first limiting plate 4231 and the second limiting plate 4232 near the cover plate 10 are bent to form a bending portion, and the bending portion is used for being fixed with the second surface 10 b. In this way, the first limiting plate 4231 and the second limiting plate 4232 are bent at the end, close to the cover plate 10, of the first limiting plate 4231 and the second limiting plate 4232 to form a bending part, so that the first limiting plate 4231 and the second limiting plate 4232 are more convenient to fix to the cover plate 10.

In one embodiment, the water replenishing mechanism 40 further includes a water replenishing pipe 43 and a control valve 44, one end of the water replenishing pipe 43 is used for being connected with an external water source, the other end of the water replenishing pipe 43 extends into the water replenishing tank 41, and the control valve 44 is arranged on the water replenishing pipe 43 and used for controlling on-off of the water replenishing pipe 43 according to the liquid level in the water replenishing tank 41.

Illustratively, the water replenishing tank 41 is connected with an external water source through the water replenishing pipe 43, and the on-off of the water replenishing pipe 43 is controlled by the control valve 44, so that automatic liquid replenishing can be realized according to the liquid level in the water replenishing tank 41, manual operation is not needed, and the labor intensity of workers is reduced.

It should be noted that, the level monitoring in the water replenishing tank 41 may be determined according to the type of the control valve selected. For example: if the control valve 44 is an electromagnetic valve, a liquid level meter needs to be additionally arranged in the water supplementing tank 41, and the on-off of the electromagnetic valve is controlled according to the monitoring result of the liquid level meter; if the control valve is a float valve, no additional level gauge is required in the water replenishment tank 41.

In one embodiment, the control valve 44 is a ball float valve that is provided at a portion of the refill tube that extends into the refill tank 41. In this way, the float valve can control the water replenishing pipe 43 according to the level of the water in the water replenishing tank 41, for example: if the liquid level in the water replenishing tank 41 is higher, the float valve is floated upwards due to larger buoyancy, so that the valve body in the float valve is closed, and the water replenishing pipe is in a closed state; if the liquid level in the water replenishing tank 41 is low, the float valve is subjected to small buoyancy and moves downwards, so that the valve body in the float valve is opened, and the water replenishing pipe is in a conducting state.

In one embodiment, a flaring is formed at one end of the water inlet pipe 421 extending into the limiting cavity 423a, and a sealing ring is disposed on the inner wall of the flaring. Illustratively, the end of the water inlet pipe 421 extending into the limiting cavity 423a is provided with a flaring, so that the liquid flowing out of the water inlet pipe 421 can be accelerated, and the liquid supplementing efficiency is faster. Meanwhile, the sealing ring is arranged on the inner wall of the flaring so that when the flaring is plugged by the plug 422, the plug 422 is abutted with the sealing ring, and the plugging effect on the water inlet pipe 421 is further enhanced.

In one embodiment, the stirring apparatus further comprises a cylinder 50 extending along the vertical direction of the cover plate 10, and the cylinder 50 is connected to the middle of the second surface 10b and is used for guiding the stirring shaft to penetrate through the cover plate 10 along the vertical direction of the cover plate 10. Illustratively, the cylinder 50 disposed in the middle of the second surface 10b can guide the stirring shaft through the cover plate 10, avoiding problems such as tilting of the stirring shaft during penetration of the stirring shaft.

In one embodiment, the plug 422 is made of an elastic rubber material.

For example, when the liquid level of the liquid in the water seal tank 20 is high, the plug 422 located in the limiting cavity 423a is subjected to a large buoyancy force, so that the plug 422 approaches the water inlet pipe 421 and extends into the end portion of the limiting cavity 423a to abut against the end portion, and the plug 422 deforms to cling to the port of the water inlet pipe 421, thereby blocking the water inlet pipe 421. In addition, the elastic rubber material may be a rubber material with elasticity in the prior art, and it is only required that the plug 422 is capable of deforming to plug the port of the water inlet pipe 421 when the plug 422 is made to abut against the port of the water inlet pipe 421 extending into the limiting cavity 423a, which is not limited in particular.

In one embodiment, a window 60 is provided on the surface of the tank 41, and the window 60 is used to observe the liquid level in the tank 41.

Illustratively, the operator can observe the liquid level condition in the water replenishing tank 41 at any time through the window 60, so as to avoid that the liquid cannot be timely replenished into the water sealing tank 20 due to the fact that the liquid is not replenished into the water replenishing tank 41 from the outside, so that the end, facing the second surface 10b, of the water sealing member 30 is not immersed into the liquid, and therefore, the organic gas escapes.

In one embodiment, a vent pipe 70 communicating with the water replenishment tank 41 is connected to one side of the water replenishment tank 41. Thus, by arranging the vent pipe 70 communicated with the water replenishing tank 41, the air pressure in the water replenishing tank 41 is balanced with the air pressure of the external air, so that the liquid in the water replenishing tank 41 flows into the limiting cavity 423a through the water inlet pipe 421 under the action of gravity, and the influence of pressure difference in the water replenishing tank 41 on the normal replenishment of the liquid in the water sealing tank 20 is avoided.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present utility model, and these modifications and substitutions should also be considered as being within the scope of the present utility model.
