[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, but the embodiments should not be construed as limiting the present invention.

[0022] The utility model provides a high-efficiency dosing device in the field of water treatment, comprising a high-efficiency dissolution and storage integrated tank 1, an automatic dispensing mechanism 2, an air power mechanism 3 and a metering dosing mechanism 4;

[0023] The automatic dispensing mechanism 2 transports the solid medicine to the dosing port 101 above the high-efficiency dissolution and storage integrated tank 1, automatically adds the solid medicine into the high-efficiency dissolution and storage integrated tank 1, and automatically adds water at the same time; the air power mechanism 3 provides compressed air, which is transported to the high-efficiency dissolution and storage integrated tank 1 through the pipeline 301, prompting the medicine to be quickly dispersed and evenly mixed in the high-efficiency dissolution and storage integrated tank 1; the metering and dosing mechanism 4 adds the mixed liquid medicine to the dosing point.

[0024] The high-efficiency integrated dissolution and storage tank 1 comprises a dosing port 101, a water inlet 102, a dissolution area 103, a storage area 104, orifice plates 105 / 106 / 107, perforated tubes 108 / 109 / 110, a drug outlet 111, a base 112, and a cylinder 113. Solid medication enters the high-efficiency integrated dissolution and storage tank 1 through the dosing port 101, which is positioned to facilitate docking with the automatic dispensing mechanism 2. The water inlet 102 connects to the water inlet pipe 206 to provide the necessary water for the dissolution process. The base 112 supports the entire tank and may also contain auxiliary equipment such as a sewage outlet. After the solid medicine is added into the high-efficiency dissolution and storage integrated tank 1, compressed air is transported to the dissolution area 103 by the perforated pipes 108 / 109 / 110. The solid medicine passes through the orifice plate 105, orifice plate 106, and orifice plate 107 in the dissolution area 103 in turn, and is quickly dispersed and dissolved under the stirring action of the compressed air transported by the perforated pipes 108, perforated pipes 109, and perforated pipes 110 corresponding to each layer; the homogenized liquid medicine is transported to the dosing point through the metering dosing mechanism through the medicine outlet 111.

[0025] The diameter of the drug dissolving zone 103 is 55%-60% of the diameter of the high-efficiency dissolving and storing integrated tank 1, and the distance between the bottom of the drug dissolving zone 103 and the bottom of the high-efficiency dissolving and storing integrated tank 1 is maintained at 15%-20% of the tank body height. To ensure that the solid medicine can be quickly dispersed and dissolved, there are three layers of orifice plates in the drug dissolving zone, and the apertures decrease step by step, which helps to quickly disperse and dissolve the solid medicine. The material of the orifice plate can be selected from PVC, ABS or stainless steel according to the type of dissolved medicine. The aperture of the first layer orifice plate 105 is 30-50mm, the aperture of the middle layer orifice plate 106 is 15-20mm, and the aperture of the bottom layer orifice plate 107 is 5-8mm. The area of the holes in each layer accounts for 40%-45% of the total area of the orifice plate. Air stirring is used to avoid direct contact between metal parts such as the stirring paddle and corrosive medicine, greatly reducing the risk of corrosion. At the same time, materials that are easy to agglomerate, have high viscosity or contain solid particles can be quickly dispersed. Perforated tubes are installed 100-150mm below each layer of perforated plates and connected to the air dynamic mechanism. The diameter of the first layer perforated tubes 108 is 15-20mm, the diameter of the middle layer perforated tubes 109 is 8-10mm, and the diameter of the bottom layer perforated tubes 110 is 3-5mm. Each perforated tube has two rows of holes, and both rows of holes are located at the top of the perforated tube. Each row of holes forms a 45° angle with the axis of the corresponding perforated tube to avoid unnecessary foaming and bleeding, ensuring the mixing effect and system stability. The perforated tube material can be selected from PVC, ABS, or stainless steel according to the type of dissolved agent.

[0026] The automatic dispensing mechanism 2 includes a medicine hopper 201, a track 202, a limit device 203, a sensor 204, an induction switch 205, a water inlet pipe 206 and a water inlet electric valve 207; the solid medicine is placed in the medicine hopper 201 and transported to the top of the high-efficiency dissolution and storage integrated tank 1 through the track 202. The limit device 203 is equipped with a sensor 204, and the medicine hopper 201 is equipped with an induction switch 205. When the medicine hopper 201 is in the limit position, the sensor 204 and the induction switch 205 are in contact and an electrical signal is sent. The discharge port gate 20104 of the medicine hopper 201 is activated, and the solid medicine enters the high-efficiency dissolution and storage integrated tank 1. At the same time, the water inlet electric valve 207 on the water inlet pipe 206 is activated to allow water to enter the high-efficiency dissolution and storage integrated tank 1 for dissolution and dispensing.

[0027] A stirring device 20101 is installed within the medicine hopper 201 to prevent the solid medicine from clumping. The stirring device 20101 is composed of alternating double straight-bladed stirring paddles of varying lengths. The long stirring paddle is 60% of the diameter of the top opening of the medicine hopper 201, and the short stirring paddle is 30% of the diameter of the top opening of the medicine hopper 201. Behind the medicine hopper 201 is a vertical track groove 20105 and a transverse track groove 20106 that are compatible with the track 202. The transverse track groove 20106 cooperates with the horizontal section of the track 202, while the vertical track groove 20105 cooperates with the vertical section of the track 202. The vertical track groove 20105 and the transverse track groove 20106 form a cross-shaped structure that is interconnected. The discharge gate 20104 of the medicine hopper 201 is composed of two curved plates. A transmission device 20103 is set on the other side of the medicine hopper 201 opposite to the vertical track groove 20105 and the horizontal track groove 20106. The medicine hopper 201 passes through the track 202 and reaches the limit device 203. The sensor 204 and the induction switch 205 contact and send an electrical signal. The pneumatic rod 20102 located on one side of the medicine hopper 201 is actuated, and the pneumatic rod 20102 pulls a curved plate hinged to it to move upward. The gear 20107 of the transmission device 20103 engages and rotates to make the two connecting parts 20108 move to both sides, thereby driving the two curved plates of the discharge gate 20104 to open, thereby realizing automatic addition of solid medicines.

[0028] The pneumatic mechanism 3 includes a compressed air pipe 301, an air tank 302, and a regulating valve 303. The air tank 302 stores compressed air to support continuous mixing operations and is connected to the high-efficiency dissolution and storage tank via a pipe 301. A regulating valve 302 is provided on each pipe to adjust the air volume in each layer of perforated tubes in the dissolution zone 103 to optimize the mixing effect. The metering and dosing mechanism 4 includes a dosing pipe 401, a metering pump 402, and a diaphragm valve 403. The prepared liquid agent is provided with a stable pressure by the metering pump 402 to ensure accurate addition of the agent. The agent is then transported to the dosing point via the dosing pipe 401. By adjusting the opening of the diaphragm valve 403, the agent flow through the dosing pipe is precisely controlled to meet the needs of different dosing points.
