During the manual preparation process, especially when adding ammonia gas or concentrated ammonia water, improper operation can easily cause ammonia volatilization and leakage, causing harm to the health of the operator. Manual preparation has great safety hazards. In order to accurately, efficiently and safely prepare ammonia water of the required concentration, people are using more automatic ammonia dispensing devices, which are widely used in chemical, environmental protection, laboratory and other fields to meet the use of ammonia water in different scenarios.

[0003] The existing Chinese patent with publication number CN213085554U discloses an automatic ammonia dosing device, including a preparation tank, a dosing pump equipped with a drug delivery tube, a control valve installed on the drug delivery tube, a shunt tube installed at one end of the drug delivery tube, an orifice plate is provided on one side of the preparation tank, a shunt tube is installed at one end of the drug delivery tube, and the shunt tube and the orifice plate are installed correspondingly, so that the drug liquid can be evenly distributed during the addition process, and the efficiency of mixing and stirring can be improved.

[0004] With regard to the above-mentioned related technologies, the problem is that during the preparation process of ammonia water, part of the ammonia water will volatilize into ammonia gas, which increases the demand for ammonia water used for preparation and causes a waste of resources. Utility Model Content

[0005] The utility model aims to provide an automatic ammonia water dispensing device. By adopting the device to work, the problem that part of the ammonia water will volatilize into ammonia gas during the preparation process of the ammonia water is solved, which increases the demand for ammonia water used for preparation and causes waste of resources.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic ammonia dispensing device, including a dosing room, a liquid storage tank is installed inside the dosing room, a dispensing tank is arranged on one side of the liquid storage tank, a pressurizing component is installed inside the dispensing tank, a water replenishing tank is installed on one side of the dispensing tank, a controller is installed on the upper side of the liquid storage tank and the water replenishing tank, the pressurizing component includes a rotating tube, an isolation plate is installed on the dispensing tank, a threaded groove is opened on the upper end of the dispensing tank, the rotating tube is rotatably installed on the isolation plate, and an annular rack is arranged on the outer fixed sleeve of the rotating tube, A gear is meshed on one side of the annular rack, and the gear is rotatably installed on the upper side of the isolation plate. A motor is installed on the gear, and the motor is fixedly installed on the medicine dispensing tank. Spline grooves are provided on both sides of the inner wall of the rotating tube, and a rotating rod is slidably provided inside the rotating tube. Key teeth are provided on both sides of the rotating rod, and the key teeth and the spline grooves are slidably connected.

A pressure block is rotatably installed on the rotating rod, and the pressure block fits tightly against the inner wall of the medicine dispensing tank. A plurality of stirring rods are fixedly installed on the lower end of the rotating rod.

[0007] Start the motor, and the driving end of the motor drives the gear to rotate, thereby driving the annular rack to rotate, so that the rotating tube rotates, and the rotation of the rotating tube drives the rotating rod to rotate. While the rotating tube rotates, it moves downward along the spline groove, driving the pressure block to move downward, reducing the gas volume on the lower side of the pressure block, and increasing the gas pressure in the dispensing tank. The increased pressure can make ammonia more inclined to dissolve in water to form ammonia water, rather than volatilize into the air, thereby reducing the volatilization of ammonia during the preparation of ammonia water and avoiding the waste of resources. While the gas in the dispensing tank is pressurized, the key teeth reach the bottom of the spline groove, and the rotating rod stops moving downward. The rotating rod rotates only driven by the rotating tube, so that the stirring rod at the lower end of the rotating rod slowly stirs the ammonia water, thereby accelerating the mixing of the ammonia water.

[0008] Preferably, a liquid inlet pipe is installed on one side of the liquid storage tank, a liquid outlet pipe is installed on one side of the medicine dispensing tank, a liquid guide pipe is installed between the liquid storage tank and the medicine dispensing tank, and a liquid guide pipe is also installed between the medicine dispensing tank and the water replenishment tank.

[0013] The rotating rod rotates under the drive of the motor, and at the same time drives the stirring rod to rotate, and the stirring rod slowly stirs the ammonia water at the bottom of the dispensing tank.

[0014] Preferably, a condenser is fixedly mounted on the upper side of the pressure block.

[0015] The condenser cools the dispensing tank to prevent the ammonia water in the dispensing tank from volatilizing into ammonia gas due to excessive temperature. At the same time, the volatilized ammonia gas can be condensed back into ammonia water, reducing the waste of resources.

[0016] Preferably, a rotating ring is fixedly mounted on the rotating rod, the upper end of the rotating ring is rotatably connected to the lower end of the pressure block, and scrapers are fixedly mounted on both sides of the rotating ring, and the scrapers are tightly fitted to the lower side of the pressure block.

[0017] The rotating rod drives the rotating ring to rotate, and the rotation of the rotating ring drives the scraper to rotate, so that the scraper scrapes the condensed and adsorbed ammonia water on the lower side of the pressure block to the bottom of the dispensing tank, thereby recovering the volatilized ammonia water.

[0018] Preferably, a glass door is rotatably installed on one side of the dosing room, ammonia alarms are fixedly installed on both sides of the inner wall of the dosing room, a fan is fixedly installed on the upper end of the dosing room, an air duct is fixedly installed on the upper side of the fan, and a gas collecting bin is fixedly installed on one end of the air duct.

[0019] The ammonia alarm detects the air in the dosing room and will sound an alarm when ammonia leakage is detected. At the same time, it will start the fan to absorb the leaked ammonia into the gas collecting bin through the air duct to prevent ammonia from leaking to the outside and causing harm to the health of the staff.

[0020] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0021] The utility model provides an automatic ammonia dispensing device, wherein a pressurizing component comprises a rotating tube and a starting motor, and the motor drives the rotating tube to rotate, so that a pressurizing block moves downward, thereby reducing the gas volume at the lower side of the pressurizing block and increasing the gas pressure in the dispensing tank. The increased pressure can make ammonia more inclined to dissolve in water to form ammonia water, rather than volatilize into the air, thereby reducing the volatilization of ammonia in the preparation of ammonia water and avoiding the waste of resources. While the gas in the dispensing tank is pressurized, the key teeth reach the bottom of the spline groove, and the rotating rod stops moving downward. The rotating rod rotates only under the drive of the rotating tube, so that the stirring rod at the lower end of the rotating rod slowly stirs the ammonia water, thereby accelerating the mixing of the ammonia water.
