[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Reference Figure 1-6 A water treatment agent dosing device includes: an agent storage box 2, the agent storage box 2 includes an upper cylindrical section, a conical section integrally connected to the upper cylindrical section and a lower cylindrical section integrally connected to the conical section, the lower cylindrical section is a discharge channel 5, and an electric-controlled discharge valve 20 is installed at the bottom end of the discharge channel 5. A PLC controller 21 is installed on the front side of the agent storage box 2, and the PLC controller 21 is electrically connected to the electric-controlled discharge valve 20 and a variable frequency motor 8. The variable frequency motor 8 is installed on the top of the agent storage box 2, and the electric-controlled discharge valve 20 and the variable frequency motor 8 can be controlled by the PLC controller 21 to work; a support frame 1 is arranged under the agent storage box 2, and a feed port 3 is opened on the top surface of the agent storage box 2, and a sealing cover 22 is installed on the top of the feed port 3. After adding new powdered agents into the agent storage box 2, the feed port 3 can be closed by the sealing cover 22, so as to prevent the powdered agents in the agent storage box 2 from getting damp or contaminated.

[0021] Two connecting rods 23 are fixed on both sides of the transmission shaft 6 located in the conical section. The two connecting rods 23 located on the same side of the transmission shaft 6 are commonly connected to a cleaning plate 24 at one end away from the transmission shaft 6. The cleaning plate 24 is in conflict with the inner wall of the medicine storage box 2. The rotation of the transmission shaft 6 drives the cleaning plate 24 to rotate through the connecting rods 23. The rotation of the cleaning plate 24 can clean the inner wall of the medicine storage box 2 to prevent powder medicine from adhering to the inner wall of the medicine storage box 2.

[0022] A support assembly is fixedly connected in the medicine storage box 2, and a screen 4 and a knocking assembly are fixedly connected to the support assembly. The screen 4 is located below the screen 4, and the knocking assembly is used to intermittently knock on the screen 4;

[0023] A transmission shaft 6 is arranged in the medicine storage box 2, and one end of the transmission shaft 6 extends out of the surface of the medicine storage box 2 and is fixedly connected to a variable frequency motor 8. The end of the transmission shaft 6 away from the variable frequency motor 8 passes through the support assembly and extends to the lower cylindrical section and is fixedly connected to an auger 7. The auger 7 is located in the lower cylindrical section, and the lower cylindrical section and the auger 7 are gap-matched. The rotation of the transmission shaft 6 drives the auger 7 to rotate, and the rotation of the auger 7 can evenly discharge the powder medicine in the medicine storage box 2, so as to achieve uniform or quantitative addition of the powder medicine and avoid blockage of the discharge channel 5. At the same time, the cleaning plate 24 is driven to rotate through the connecting rod 23. The rotation of the cleaning plate 24 can clean the inner wall of the medicine storage box 2 to avoid the powder medicine from adhering to the inner wall of the medicine storage box 2; a plurality of crushing blades 25 are fixedly connected to the transmission shaft 6 at the upper cylindrical section, and the crushing blades 25 are located above the screen 4.

[0024] Furthermore, the support assembly includes a cylindrical transmission box 26, a plurality of support tubes 10 evenly distributed along the outer circumferential surface of the transmission box 26 and fixedly connected to the transmission box 26, a vertical tube 11 connected and fixedly connected to the interior of the support tube 10, and a knocking tube 9 movably sleeved on the vertical tube 11. The support tube 10 is fixedly connected to the interior of the medicine storage box 2, and a hemispherical knocking block 19 is fixed on the top of the knocking tube 9. The hemispherical knocking block 19 is made of rubber material, so that the hemispherical knocking block 19 has a certain elasticity and softness, thereby reducing the damage to the screen 4 caused by the hemispherical knocking block 19 hitting the screen 4.

[0025] Furthermore, the knocking assembly includes a first bevel gear 12 nested and fixedly connected to the transmission shaft 6, a plurality of second bevel gears 15 meshing with the first bevel gear 12, and a rotating shaft 13 fixedly connected to each second bevel gear 15, and a cam 16 fixedly connected to one end of the rotating shaft 13 away from the second bevel gear 15, and the rotating shaft 13 is located in the support tube 10. A transmission rod 14 is arranged above the cam 16, and the transmission rod 14 is movably located in the vertical tube 11, and a roller 18 is fixedly connected to one end of the transmission rod 14 close to the cam 16, and the roller 18 conflicts with the cam 16. The interior of the transmission rod 14 is a hollow structure, and a spring 17 is installed inside the transmission rod 14, and one end of the spring 17 is fixedly connected to the inner wall of the knocking tube 9. The first bevel gear 12 is driven to rotate by the rotation of the transmission shaft 6, the first bevel gear 12 drives the four second bevel gears 15 to rotate, the second bevel gears 15 drive the rotating shaft 13 to rotate, the rotating shaft 13 drives the cam 16 to rotate, and the cam 16 intermittently lifts the transmission rod 14 during the rotation process, so that the transmission rod 14 pushes the knocking cylinder 9 to hit the screen 4, causing the screen 4 to vibrate, which is beneficial to the screening of the pharmaceutical powder on the screen 4.

[0026] During operation, after the powder medicine enters the medicine storage box 2 through the feed port 3, the powder medicine first falls on the screen 4, and the screen 4 screens the powder medicine. Small particles of powder pass through the screen 4 and fall below the screen 4, and large particles of powder or agglomerated powder blocks are intercepted on the screen 4, which effectively reduces the blockage caused by powder agglomeration and ensures the looseness of the powder medicine, which is conducive to the rapid integration of the powder medicine into the sewage after the later addition. At the same time, the frequency conversion motor 8 works to drive the transmission shaft 6 to rotate, and the rotation of the transmission shaft 6 drives the crushing blade 25 to rotate. The crushing blade 25 crushes the large particles of powder or agglomerated powder blocks on the screen 4. At the same time, the transmission shaft 6 rotates to drive the first bevel gear 12 to rotate, and the first bevel gear 12 rotates to drive the four second bevel gears 15 to rotate. The second bevel gear 15 rotates to drive the rotating shaft 13 to rotate, and the rotating shaft 13 rotates to drive the cam 16 to rotate. During the rotation of the cam 16, the transmission rod 14 is intermittently lifted, so that the transmission rod 14 pushes the knocking cylinder 9 to hit the screen 4, causing the screen 4 to vibrate, which is conducive to the screening of the pharmaceutical powder on the screen 4.

[0027] Furthermore, when adding powder medicine to the medicine storage box 2, the frequency conversion motor 8 drives the transmission shaft 6 to rotate clockwise, and the clockwise rotation of the transmission shaft 6 drives the auger 7 to rotate clockwise. At this time, the auger 7 transports the powder medicine upward and will not discharge the powder medicine in the medicine storage box 2. When administering the medicine, the frequency conversion motor 8 drives the transmission shaft 6 to rotate counterclockwise, and the counterclockwise rotation of the transmission shaft 6 drives the auger 7 to rotate counterclockwise, so that the powder in the medicine storage box 2 is evenly transported downward to achieve discharge.
