[0025] During operation, a dosing device for sewage treatment in the above technology cannot well control the amount of the drug each time when the drug is put into the liquid storage tank through the feed port, resulting in the situation that too little or too much drug is put in. Through the structural design of the weighing mechanism, the function of facilitating the control of the amount of the drug put in is realized. When the drug is to be put in, first pull the second fixed block 36 downward, the sliding block 37 will slide inside the cavity 33, and the two groups of protrusions 40 fixed on the top of the sliding block 37 will push the two groups of baffle plates 23 to open, so that the drug in the hopper 21 can enter the interior of the casing 22, and then it can be weighed. The device 27 displays the specific weight of the dosed medicine, and the amount of medicine entering the casing 22 can be controlled by frequently pulling the second fixed block 36 up and down, so as to accurately control the amount of medicine dosed and avoid waste. At this time, after letting go, the sliding block 37 will automatically reset under the action of the two sets of connecting springs 34, and the two sets of baffle plates 23 will also close under the action of the two sets of supporting springs 24 at the bottom. This is by pulling the first fixed block 32 upward to open the discharge port 29, and the medicine inside the casing 22 will enter the interior of the liquid storage tank 1 through the feed pipe 31, wherein the bottom end of the sliding block 37 and the top end of the baffle 30 are both slidably connected to the interior of the cavity 33.

[0026] Furthermore, a stopper 38 is welded and fixed to the top of the sliding block 37. The stopper 38 is rectangular in design and has the same width as the sliding block 37. The stopper 38 is slidably connected to the inside of the receiving groove 39. The sizes of the receiving groove 39 and the stopper 38 are adapted. The receiving groove 39 is opened inside the housing 22.

[0027] During operation, through the structural design of the stopper 38 and the storage groove 39, when the second fixed block 36 is pulled to make the sliding block 37 move downward inside the cavity 33, the stopper 38 will slide out of the storage groove 39, thereby realizing the function of blocking the medicine and preventing the medicine from entering the interior of the cavity 33.

[0028] Furthermore, an inclined plate 26 is welded and fixed on the top of the support plate 28, and the support plate 28 is in contact with the inner wall of the casing 22;

[0029] During operation, the inclined plate 26 is designed so that the medicine inside the casing 22 can slide out smoothly from the discharge port 29 , thereby preventing the medicine from remaining inside the casing 22 .

[0030] Furthermore, a sealing strip 41 is glued and fixed on the baffle plate 23, and the sealing strip 41 is made of rubber;

[0031] During operation, the sealing strip 41 is made of rubber material. When the baffle plate 23 is closed, the deformation caused by the abutment between the two sets of sealing strips 41 can improve the sealing performance of the baffle plate 23 .

[0032] Furthermore, a slider 44 is welded and fixed to the left side of the baffle plate 23, and the slider 44 is slidably connected to the inside of a slide groove 45, and the slide groove 45 is provided on the inner wall of the sleeve shell 22, and the slide groove 45 is designed in an arc shape;

[0033] During operation, when the protrusion 40 pushes the baffle plate 23 to rotate downward, the slider 44 fixed on the baffle plate 23 will also slide in the slide groove 45, and the rotation angle of the baffle plate 23 is limited by the slide groove 45.

[0034] Furthermore, a cover plate 42 is rotatably connected to the top of the hopper 21, and the bottom end of the cover plate 42 is attracted to a magnet 43, and the magnet 43 is glued and fixed to the top of the hopper 21;

[0035] During operation, the top of the hopper 21 is rotatably connected to a cover plate 42 to protect the medicine stored inside the hopper 21 from external contamination, and the cover plate 42 is fixed to the hopper 21 by attraction of a magnet 43 .

[0036] Working principle: In the above-mentioned technology, a dosing device for sewage treatment cannot well control the amount of the drug put in each time when the drug is put into the liquid storage tank through the feed port, so that the drug is put in too little or too much. The structural design of the weighing mechanism realizes the function of facilitating the control of the amount of the drug put in. When the drug is to be put in, first pull the second fixed block 36 downward, the sliding block 37 will slide inside the cavity 33, and the two groups of protrusions 40 fixed on the top of the sliding block 37 will push the two groups of baffle plates 23 to open, so that the drug in the hopper 21 can enter the interior of the casing 22, and then it can be weighed. The measuring device 27 displays the specific weight of the medicine released, and the amount of medicine entering the shell 22 can be controlled by frequently pulling the second fixed block 36 up and down, so as to accurately control the amount of medicine released and avoid waste. At this time, after letting go, the sliding block 37 will automatically reset under the action of the two sets of connecting springs 34, and the two sets of baffle plates 23 will also be closed under the action of the two sets of supporting springs 24 at the bottom. This is by pulling the first fixed block 32 upward to open the discharge port 29, and the medicine inside the shell 22 will enter the interior of the liquid storage tank 1 through the feed pipe 31, wherein the bottom end of the sliding block 37 and the top end of the baffle 30 are both slidably connected to the interior of the cavity 33.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
