[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5According to an embodiment of this utility model, a controllable dosing device includes a drug storage tank 1, used for dosing in water treatment, medical, chemical, and other processes. It stores the drugs to be added, and the material must be compatible with the drugs and have sufficient sealing performance to prevent drug volatilization or contamination. The drug storage tank 1 should be equipped with a liquid level indicator (a mature technology, not described in detail here) to observe the remaining drug level. The drug storage tank 1 is also equipped with a feeding hopper 3 (for convenient drug addition; a vibration motor can be installed on the external side wall to assist in feeding and prevent residue). The feeding hopper 3 is equipped with a cover plate to cover it after adding the drug to prevent dust accumulation. An infusion device 5 is connected to the drug storage tank 1 via a connecting pipe 4, used to connect the drug storage container, metering system, and target area (such as a reaction vessel, water tank, etc.; the material must be corrosion-resistant, easy to clean, and equipped with necessary valves and filters to prevent clogging), facilitating drug dosing operations. To ensure the stability of the infusion device 5, a fixing ring 6 of a fixing component is fitted around the outside of the infusion device 5, and the fixing ring 6 is connected by a fixing rod 7. The mixture is welded and fixed to the side wall of the drug storage tank 1. A mixing device 8 (which can be composed of a motor, a rotating shaft, and mixing blades) is also installed in the middle of the drug storage tank 1 to facilitate the mixing of the internal liquid medicine. A control device 2 (mainly including a touch screen human-machine interface (HMI), a programmable logic controller (PLC), or a single-chip microcomputer) is fixed to the top of the drug storage tank 1 with screws. It is used to set the dosing parameters (such as dosage, frequency, etc.), monitor the operating status and fault alarm. The system should also have remote communication function to facilitate remote monitoring and maintenance. The control device 2 is electrically connected to the mixing device 8, the infusion device 5, and the sealing mechanism. It also has a metering system, which consists of a precision flow meter (such as a metering pump, peristaltic pump, piston pump, etc.) and a controller. It is responsible for accurately measuring the drug dosage according to the preset parameters. The flow meter should have high accuracy and stability to adapt to the characteristics of different drugs and dosing requirements. It is also equipped with an emergency stop button, overcurrent protection, leakage detection, etc. to ensure that the power can be quickly cut off and corresponding measures can be taken in case of abnormality. It is a relatively mature technology and will not be described in detail here.

[0024] Please see Figures 1-5To facilitate sealing and opening of the medicine storage box 1 without affecting normal use, and to facilitate subsequent cleaning to prevent medicine residue from affecting future use, the rear end of the medicine storage box 1 is open, with a sealing plate 10 inside the opening. To ensure airtightness, a sealing ring 13 is adhered to the periphery of the sealing plate 10. The opening end of the medicine storage box 1 has a sealing groove 15 that interferes with the sealing ring 13. The outer wall of the sealing plate 10 has symmetrical grooves 12 for easy pushing and pulling. The sealing plate 10 and the medicine storage box 1 are fixedly connected by a buckle 11 (or other methods of fixing, which can be detachable and do not affect subsequent disassembly). To ensure airtightness, the opening end of the medicine storage box 1 has a sealing groove 15 that interferes with the sealing ring 13. The wall is also embedded with an inflatable sealing bladder 16 (which can be made of rubber and have a sealing gasket attached to the outer surface to ensure a sealing effect). The side of the sealing plate 10 is provided with a positioning groove 14 that engages with the inflatable sealing bladder 16 after inflation. This helps to fix the positioning and ensures a sealing effect. The top of the medicine storage box 1 is equipped with an inflation component mounting base 17. An inflation pump 9 is fixedly installed in the mounting base 17. The output end of the inflation pump 9 is connected to an inflation pipe 18. The inflation pipe 18 passes through the medicine storage box 1 and extends into the interior to connect with the inflatable sealing bladder 16. An exhaust pipe 19 is also installed on the inflation pipe 18. An electric control valve 20 is installed on the exhaust pipe 19 to facilitate venting during subsequent disassembly and to facilitate the removal of the sealing plate 10.

[0025] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0026] In summary, with the help of the above-mentioned technical solution of this utility model, the medicine is added through the feeding hopper 3 and then mixed through the mixing device 8. During the addition of medicine, it is transported through the connecting pipe 4 and the infusion device 5, etc. The precise quantitative delivery can be ensured by the cooperation of the control device 2, etc. When the internal cleaning operation is required after use, the vent pipe 19 can be opened by operating the electric control valve 20, so that the gas in the inflatable sealing bag 16 can be discharged through the vent pipe 19. The tower buckle 11 is pulled down, and the sealing plate 10 is no longer positioned and fixed. The sealing plate 10 can be removed by cooperating with the groove 12, and the sealing ring 13 is removed. The sealing groove 15 is opened, allowing for the cleaning of the inside of the medicine storage tank 1. During rinsing and cleaning, water can be added through the feeding hopper 3 to clean the entire tank, ensuring effective cleaning. After cleaning, the sealing plate 10 can be pushed back into the opening of the medicine storage tank 1, and the sealing ring 13 can be used in conjunction with the sealing groove 15 for initial positioning and sealing. Then, the electric control valve 20 closes the exhaust pipe 19, and the air pump 9 operates. The air sealing bladder 16 can be inflated through the air inflator 18, and the positioning groove 14 can be used for resealing and positioning. Finally, the buckle 11 is tightened for connection and fixation, without affecting subsequent use.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
