[0019] Preferably, a water level sensor 17 is fixedly installed on the top side of the medicine storage cylinder 10, an electric control valve 12 is installed on the feed pipe 11, and an electric control valve 2 16 is installed on the connecting pipe; before use, the feed pipe 11 is connected to the output end of the discharge pump of the medicine liquid through a connecting piece, and the medicine discharge pipe 14 is located above the sewage pool. When in use, by opening the electric control valve 12, the medicine is transported into the inside of the medicine storage cylinder 10 through the discharge pump, and the water level sensor 17 feeds back the liquid level in the medicine storage cylinder 10. After the medicine storage cylinder 10 is fed with a proper amount of medicine liquid, the electric control valve 12 is closed, and then the electric control valve 2 16 and the metering pump 13 are respectively started by an external power supply. The input end of the metering pump 13 extracts the medicine liquid inside the medicine storage cylinder 10 through the connecting pipe, and then the output end of the metering pump 13 discharges the medicine liquid into the sewage pool through the medicine discharge pipe 14, and the damper 15 can buffer the discharged medicine liquid. Thus, the effect of auxiliary dosing when treating sewage is achieved. When the water level sensor 17 feedbacks that the height of the medicine liquid is low, the electric control valve 12 is opened again to replenish the medicine liquid in the medicine storage cylinder 10.

[0020] refer to Figure 2 , 3A stirring mechanism 20 is provided inside the drug storage cartridge 10, and the stirring mechanism 20 includes a rotating rod 202 which is rotatably connected to the upper and lower sides of the stirring mechanism 20, and a pair of threaded blades 203 which are mirror-symmetrical in upper and lower directions are fixedly connected to the outer side of the rotating rod 202; a motor 201 is fixedly connected to the top of the drug storage cartridge 10, and the output end of the motor 201 is fixedly connected to the rotating rod 202.

[0021] Furthermore, a group of movable rods 204 that are centrally symmetrical and rotatable in the same direction are arranged inside the drug storage cartridge 10, the top and bottom of the movable rods 204 are rotatably connected to the inner top and inner bottom of the drug storage cartridge 10 respectively, and the rotating rod 202 is located at the center of a group of movable rods 204, and multiple groups of vertically arranged stirring blades 205 are fixedly connected to the outer side of the movable rods 204.

[0022] Specifically, the outer sides of the group of movable rods 204 are respectively fixedly connected with synchronous pulleys 208, and the outer sides of the group of synchronous pulleys 208 are commonly meshed with a transmission belt 209; the outer side of the rotating rod 202 is fixedly connected with a synchronous pulley 1 206, and the outer side of the front right movable rod 204 is fixedly connected with the same synchronous pulley 1 206, and the outer sides of the two synchronous pulleys 206 are commonly meshed with a transmission belt 1 207.

[0023] After the drug liquid is injected into the drug storage cartridge 10 , since the drug liquid is usually a mixture of multiple components, during the storage process, due to the different properties of the components such as density and solubility, stratification, precipitation and the like may occur. In order to avoid this phenomenon, a stirring mechanism 20 is proposed; when in use, the motor 201 is started by an external power supply, and the output end of the motor 201 drives the rotating rod 202 to rotate, thereby driving a pair of threaded blades 203 to rotate in the same direction. Since the threaded blades 203 are mirror-symmetrical, when rotating, the upper medicine flows downward with the rotation of the upper threaded blades 203, and the upper medicine flows upward with the rotation of the lower threaded blades 203, thereby mixing the medicines inside the medicine storage cartridge 10 to prevent the medicine from being stratified and precipitated; at the same time, the rotation of the rotating rod 202 will rotate the movable rod 204 at the right end of the front side through the transmission of the synchronous pulley 1 206 and the transmission belt 1 207, and then a group of movable rods 204 are rotated in the same direction through the transmission of the synchronous pulley 208 and the transmission belt 209, so that all stirring blades 205 stir the medicine at the boundary, thereby reducing the stirring dead angle of the medicine and achieving the effect of completely stirring the medicine.

[0024] refer to Figure 1 , 4A moving mechanism 30 is provided at the bottom of the medicine storage cartridge 10, and the moving mechanism 30 includes a support frame 301. A pair of flip rods 303 that can flip back and forth are respectively provided on the left and right sides of the bottom of the support frame 301, and the front and rear ends of the flip rods 303 are respectively rotatably connected to the support frame 301; the front and rear sides of the flip rod 303 are respectively fixedly connected with support rods 304, and a universal wheel 305 is fixedly installed at the bottom of the support rod 304.

[0025] Specifically, the inner top of the support frame 301 is fixedly connected to a two-way cylinder 302 through a mounting part, and the left and right output ends of the two-way cylinder 302 are respectively fixedly connected to toothed plates 307; the outer sides of the two flip rods 303 are fixedly connected to gears 306, and the two toothed plates 307 are respectively meshed with corresponding side gears 306.

[0026] The spatial layout of a sewage treatment plant often needs to be adjusted according to different process requirements and equipment placement. After the mobile mechanism 30 is set, the drug storage cartridge 10 can be flexibly moved according to actual needs, and can better adapt to changes in different treatment processes and equipment layouts, so that limited space can be used more reasonably. When upgrading or maintaining the dosing device, the drug storage cartridge 10 can be moved to a suitable position to provide maintenance personnel with sufficient operating space to facilitate maintenance, replacement of parts, etc., while also avoiding the space cramped problem that may be caused by the fixed installation of the drug storage cartridge 10. Therefore, a mobile mechanism 30 is proposed.

[0027] When the medicine storage cartridge 10 needs to be moved, the two-way cylinder 302 is started by an external power supply, and the left and right output ends of the two-way cylinder 302 extend outward to drive the tooth plates 307 on both sides to move outward, and the transmission of the tooth plates 307 and the gear 306 drives the flip rod 303 to flip inward, so that the support rods 304 and the universal wheels 305 on both sides flip inward, until the support rods 304 flip to a vertical state and the universal wheels 305 contact the ground, and then the whole device is moved by pushing. When the whole device needs to be stopped at a certain position, the two-way cylinder 302 is started by an external power supply, and the output end of the two-way cylinder 302 is contracted, so that the support rods 304 and the universal wheels 305 on both sides flip back to back, so that the universal wheels 305 are off the ground after flipping, and the whole device is supported by the support frame 301, so as to achieve the effect of device positioning.

[0028] The working principle of the utility model is as follows: the motor 201 is started by an external power supply, and the output end of the motor 201 drives the rotating rod 202 to rotate, thereby driving a pair of threaded blades 203 to rotate in the same direction. Since the threaded blades 203 are mirror-symmetrical, when rotating, the upper medicine flows downward with the rotation of the upper threaded blades 203, and the upper medicine flows upward with the rotation of the lower threaded blades 203, thereby mixing the medicines inside the medicine storage cartridge 10 to prevent the medicine from being stratified and precipitated; at the same time, the rotation of the rotating rod 202 will rotate the movable rod 204 at the right end of the front side through the transmission of the synchronous pulley 1 206 and the transmission belt 1 207, and then a group of movable rods 204 are rotated in the same direction through the transmission of the synchronous pulley 208 and the transmission belt 209, so that all the stirring blades 205 stir the medicine at the boundary, thereby reducing the stirring dead angle of the medicine, and achieving the effect of completely stirring the medicine.
