Technical Field

[0001] The utility model relates to the technical field of ammonia water storage, in particular to an ammonia water storage tank. Background Art

[0002] The main component of ammonia water is ammonia water, which is colorless, transparent and has a pungent odor. Ammonia water is volatile and has the general properties of some alkalis. It is made by passing ammonia gas into water and is widely used in various industries. Ammonia water is usually stored in storage tanks and can be transported to the corresponding process through pipelines when needed.

[0003] For example, the utility model patent with application number CN202321696302.8 proposes a real-time analysis and detection system for ammonia water for cement production, wherein a liquid level meter is embedded and fixed on the front end surface of the ammonia water storage tank, and a liquid inlet pipe is embedded and fixed on the top end surface of the ammonia water storage tank;

[0004] However, when the above-mentioned ammonia storage tank is being refilled, if the liquid level in the storage tank is low, the ammonia added from the top of the storage tank has a certain potential energy and collides with the ammonia in the storage tank, which is very easy to volatilize and form ammonia gas. The ammonia content in the tank body continues to increase, and the pressure in the tank body continues to increase, which can easily cause damage to the tank body and pipelines.

[0009] Furthermore, it also includes a material control component, and the top ends of the multiple feed pipes are externally connected to ammonia water through the material control component. The material control component controls the opening of the corresponding feed pipes according to the liquid level height in the tank body.

[0010] Furthermore, the material control assembly includes a guide tube, a sliding tube and a sealing piece. The guide tube is fixedly arranged on the top of the tank body. The top ends of the plurality of feed pipes are sequentially connected with the guide tube in the vertical direction. The bottom end of the sliding tube extends into the guide tube and is slidably connected with the guide tube. The bottom of the sliding tube is connected with the sealing piece and is provided with a through hole. The sliding tube can slide to a position where the sealing piece blocks the top end of any feed pipe, and the feed pipe is arranged opposite to the through hole.

[0011] Furthermore, the sealing member includes a first piston ring and a second piston ring, and the first piston ring and the second piston ring are sequentially sleeved on the bottom of the sliding tube in a vertical upward direction, and the first piston ring and the second piston ring are both slidably and sealedly connected to the inner wall of the guide tube, and the distance between the first piston ring and the second piston is greater than the diameter of the top end of the feed pipe, and the through hole is opened at the side wall of the feed pipe between the first piston ring and the second piston ring.

[0012] Furthermore, the bottom end of the sliding tube is closed, and the top end of the sliding tube is externally connected to ammonia water.

[0013] Furthermore, the material control assembly also includes a driving member, which is installed on the side wall of the guide tube, and the output end of the driving member is connected to the sliding tube to drive the sliding tube to slide.
