Description

Technical Field

[0001] The utility model relates to the technical field of chemical reagent batching, in particular to a leakage-proof chemical reagent batching tank. Background Art

[0002] Chemical reagents are widely used in chemical production and new energy industries. Taking acids and alkalis as an example, they usually need to be mixed with water or other solvents to form solutions of a certain concentration for use. A large amount of steam and dust will be generated during the mixing process, resulting in inaccurate measurement, environmental pollution and even harm to the health of operators. During use, the prepared solution is usually highly corrosive, and some reagents are highly volatile, which places extremely stringent requirements on the corrosion protection of conveying equipment. In order to avoid pollution caused by volatilization during use and to avoid harm to operators, the use environment and personnel protection are also extremely demanding, thereby increasing the cost of use. The storage of relevant reagents after configuration also needs to take into account the leakage of pollutants and solution deterioration caused by volatilization (such as hydrochloric acid) and reactions with air components (such as the reaction of alkaline solutions with carbon dioxide in the air).

[0003] Therefore, designing a container that can accurately control the input and output volume in a closed tank and ensure safe operation when preparing acid and alkali liquids is crucial for the mixing, storage and use of chemical reagents during use. Utility Model Content

[0006] Furthermore, the air inlet and outlet valves are also connected to a filter tube, and the filter tube is filled with a filter material for preventing the volatile substances in the sealed can from leaking out.

[0007] Furthermore, the filter tube is arranged on the top of the sealed tank in a bent shape.

[0008] Furthermore, the float liquid level controller is arranged away from the inlet and outlet pipes and the inlet and outlet valves.

[0009] Furthermore, the inlet and outlet pipes extend to the inner bottom of the sealed tank, and the inner bottom surface of the sealed tank is inclined toward the position of the inlet and outlet pipes.

[0010] Furthermore, the sealed can includes a can body and a cover plate sealedly connected to the can body.

[0011] The beneficial effects of the present invention are as follows:

[0012] The utility model discloses a leakage-proof chemical reagent batching tank which controls the amount of liquid to be added and discharged by adjusting a float liquid level controller. The air inlet and outlet valves are used to make the sealed tank in a negative pressure state and a positive pressure state respectively during the inlet and outlet of the material, and the liquid is driven to enter and be discharged from the tank through the inlet and outlet valves. The overall process realizes contactless feeding and discharging in positive and negative pressure experiments and accurately controls the inlet and outlet amounts by the float liquid level.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] See also Figure 1 .

[0018] The utility model discloses a leak-proof chemical reagent dispensing tank, comprising a sealed tank 1, a float level controller 2 with a detection unit located within the sealed tank 1, an air inlet and outlet valve 3 connecting the sealed tank 1 to the outside world, an inlet and outlet pipe 4, and an inlet and outlet valve 5 connected to the inlet and outlet pipe 4. The float level controller 2 is used to control the amount of liquid to be added or discharged, the air inlet and outlet valve 3 is used to connect to an air source or vacuum pump to achieve positive or negative pressure in the sealed tank 1, and the inlet and outlet pipe 4 is used to extract liquid when the sealed tank 1 is under negative pressure and to discharge liquid when the sealed tank 1 is under positive pressure. This design allows the overall process to achieve contactless feeding and discharging of materials in positive and negative pressure experiments, while accurately controlling the inlet and outlet amounts through the float level.

[0019] The specific feeding and discharging process of the anti-leakage chemical reagent batching tank of the utility model is as follows:

[0020] When feeding the reagent ingredients, the amount of liquid to be added is controlled by adjusting the float liquid level controller 2, the vacuum pump is connected through the inlet and outlet valves 3, and the inlet and outlet valves 5 are connected to the liquid to be extracted. The gas is extracted by the vacuum pump to form a negative pressure in the tank, so that the liquid automatically enters the tank from the inlet and outlet valves 5. When the liquid reaches the liquid level preset by the float liquid level controller 2, the inlet and outlet valves 3 are closed, and then the inlet and outlet valves 3 are switched to connect the inert gas, and the inlet and outlet valves 3 are opened. After the air pressure in the tank is filled to one atmosphere, the inlet and outlet valves 3 are closed.

[0021] When discharging the reagent ingredients, the float level controller 2 controls the amount of liquid to be added, and the inlet and outlet valves 3 are connected to the gas source to increase the pressure of the internal inert gas. At this time, the tank is under positive pressure. When the liquid in the tank is discharged through the inlet and outlet valves 5 under the pressure of the gas, when the preset liquid level of the float level controller 2 is reached, the inflation is stopped and the gas source is removed. The excess gas causing the positive pressure in the tank is discharged from the inlet and outlet valves 3. After the pressure is balanced with the external pressure, the inlet and outlet valves 3 can be closed.

[0022] The opening and closing of the float liquid level controller 2, the inlet and outlet valves 5, and the inlet and outlet valves 3 can be controlled in a unified manner through the control terminal.

[0023] In this embodiment, see Figure 1 The inlet and outlet valves 3 are also connected to a filter tube 6, and the filter tube 6 is filled with a filter material for preventing the volatile substances in the sealed tank 1 from leaking out. Among them, there are acid-removing filter materials for acidic liquids such as hydrochloric acid, alkali-removing filter materials for alkaline liquids such as ammonia water, and organic matter-removing filter materials for organic liquids. In this design, the filter tube 6 is adapted to the filter material to prevent the volatile substances in the tank from leaking out, the external active gas does not contaminate the reagents in the tank, and the gas in the tank will not leak through the filter tube 6. After being processed by the filter tube 6, the vacuum pump required for extracting negative pressure does not need to be anti-corrosion treated, thereby reducing the preparation process and improving the use efficiency.

[0024] In this embodiment, see Figure 2 , the filter tube 6 is bent and arranged on the top of the sealed tank 1. This design extends the filtration path of the filter tube 6, enhances the filtration effect, and wherein the filter tube 6 is laid flat on the top of the sealed tank 1, ensuring the aesthetics of the sealed tank 1.

[0025] In this embodiment, see Figure 2 The float liquid level controller 2 is arranged away from the inlet and outlet pipes 4 and the inlet and outlet valves 3. This design avoids the impact of gas and water flow on it.

[0026] In this embodiment, see Figure 1 The inlet and outlet pipes 4 extend to the inner bottom of the sealed tank 1, and the inner bottom of the sealed tank 1 is inclined toward the inlet and outlet pipes 4. This design ensures that the liquid in the tank can be discharged when discharging.

[0027] In this embodiment, see Figure 1 The sealed can 1 includes a can body 101 and a cover plate 102 sealed with the can body 101. This design makes the sealed can 1 simple in structure and easy to prepare, and wherein the air inlet and outlet valves 3, the inlet and outlet valves 5 and the inlet and outlet pipes 4 are all connected to the cover plate 102.
