[0027] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6The present invention provides a technical solution: a dosing device for a water treatment pool, comprising a water pool 1, with a dosing mechanism 2 provided at one end of the top of the water pool 1; the dosing mechanism 2 comprises a dry powder box 21 and a mounting turntable 25, the dry powder box 21 being located at one end above the water pool 1, the mounting turntable 25 being located in the middle of the left end of the inner side of the dry powder box 21, a cam rod 26 being provided on the rear side of the right end of the mounting turntable 25, a vibrating particle board 29 being provided below the mounting turntable 25, a connecting swivel 211 being provided at both the left and right ends of the bottom of the vibrating particle board 29, the connecting swivel 211 being rotatably connected to the inner wall of the dry powder box 21, a main gear 219 being fixedly connected to the middle of the left end of the mounting turntable 25, and a driving motor 218 being fixedly connected to the middle of one end of the main gear 219, The middle part of the bottom end of the main gear 219 is meshed with the sub-gear 220. A connecting support plate 22 is installed on both ends of the dry powder box 21. The bottom end of the connecting support plate 22 is fixedly connected to the top of the water pool 1. The upper clamp of the dry powder box 21 has a box cover 24. A drug delivery tube 23 is welded below the right end of the dry powder box 21. The middle part of the right end of the sub-gear 220 is fixedly connected to a screw 27. The screw 27 passes through the middle part of the connecting ring 211 and the middle part of the dry powder box 21 from left to right. When adding medicine, pour the flocculant (PAM) dry powder into the dry powder box 21 for storage. If the poured flocculant (PAM) is in large lumps, the lumpy flocculant (PAM) will be blocked above the vibrating particle board 29, and the mixed The powder will be filtered into the vibrating particle board 29 under the action of gravity, and the normal flocculant particles without agglomerates will pass through the gap between the vibrating particle board 29 and the dry powder box 21 and flow to the bottom of the vibrating particle board 29. The drive motor 218 is started, and the drive motor 218 drives the main gear 219 fixedly connected to the output end to rotate, thereby driving the mounting turntable 25 fixedly connected to one end of the main gear 219 and the sub-gear 220 meshing with the bottom of the main gear 219 to rotate synchronously. The rotating sub-gear 220 will drive the screw 27 fixedly connected to one end to rotate to push the flocculant particles that fall under the vibrating particle board 29. When the rotating mounting turntable 25 drives the cam rod 26 provided at one end to move to the vibrating particle board When the cam rod 26 rolls the block-shaped flocculant, the flocculant retained on the vibrating chip plate 29 is rolled to break it, and the flocculant broken into particles falls from the gap between the vibrating chip plate 29 and the dry powder box 21 to the bottom of the vibrating chip plate 29. The cam rod 26 drives the vibrating chip plate 29 to vibrate when rolling the block-shaped flocculant. Under the action of the vibration force, the powdered flocculant on the inside of the vibrating chip plate 29 slides to one end along the inclined angle of the inner side of the vibrating chip plate 29 and falls to the mouth of the drug delivery tube 23.

[0028] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 An adjusting gear ring 28 is provided between the left end of the mounting turntable 25 and the inner wall of the dry powder box 21. The middle part of the left end of the mounting turntable 25 passes through the middle part of the left end of the dry powder box 21 and the connecting support plate 22 connected to the left end of the dry powder box 21, and is fixedly connected to the main gear 219. A supporting hoop plate 221 is provided below the driving motor 218. The supporting hoop plate 221 is fixed to the bottom of one end of the connecting support plate 22 by a nut.

The inner side of the vibration particle board 29 is fixedly connected to the drainage inclined plate 212. The right end of the drainage inclined plate 212 A rectangular drainage port is provided in the middle, and the cross-sectional view of the side of the drainage inclined plate 212 is V-shaped, and the drainage inclined plate 212 is composed of two inclined surfaces inclined from left to right. A plurality of tooth grooves are provided at the lower angles of the front and rear sides of the adjusting tooth ring 28, and the tooth grooves are engaged with one end of the cam rod 26. Before pushing the material blocks and slag, the rotating mounting turntable 25 drives the cam rod 26 provided at one end to move along the trajectory of the adjusting tooth ring 28 to the oblique upper part of the vibrating chipboard 29. The tooth grooves provided at the lower rear side of the adjusting tooth ring 28 will push the engaged cam rod 26 to produce a counterclockwise rotation of 180. When the rotating cam rod 26 contacts the surface of the vibrating particle board 29 at the raised position, it will push one end of the vibrating particle board 29 in contact below to rotate downward under the restriction of the connecting ring 211. At the same time, the rotating cam rod 26 will roll the block flocculant to disperse it. When the raised position of the cam rod 26 is separated from the surface of the vibrating particle board 29, the rebound force generated by the spring provided under the vibrating particle board 29 when the vibrating particle board 29 loses its pushing force will drive the vibrating particle board 29 to vibrate. When the cam rod 26 moves to the vibrating position under the drive of the mounting turntable 25, it will move to the vibrating position. When the particle board 29 is above the front side, the block flocculant is rolled and crushed in the same way, and the vibration particle board 29 is driven to vibrate. When the vibration particle board 29 vibrates, the powder flocculant that passes through the filter plate 210 and falls onto the drainage inclined plate 212 will slide into the rectangular drainage port fixed at one end of the top of the drainage inclined plate 212 along the inclined angle of the drainage inclined plate 212 under the action of the vibration force, and fall into the pipe mouth of the drug delivery tube 23 along the rectangular drainage port, which is convenient for pushing the block flocculant and the powder flocculant, improving the cleanliness of the drug delivery, and reducing the waste of drug resources.

[0029] See also Figure 2 、 Figure 3 、 Figure 5 and Figure 7One end of the cam rod 26 passes through the mounting turntable 25 and is slidably connected to the adjusting gear ring 28. A storage cavity 213 is provided in the middle of the rear side of the cam rod 26. A positioning frame plate 214 is slidably connected to the inner side of the storage cavity 213. The rear side of the positioning frame plate 214 is rotatably connected to a scraper plate 216. A fixed slot 217 is provided at the bottom end of the front side of the scraper plate 216. A fixed clip 215 is provided between the rear side of the positioning frame plate 214 and the scraper plate 216. The bottom end of the front side of the fixed clip 215 is fixedly connected to the side wall of the rear side of the positioning frame plate 214. At the end of the drug delivery, the staff manually pulls the positioning frame plate 214 so that the positioning frame plate After 214 slides out of the storage cavity 213 provided on the inner side of the cam rod 26 by half, the scraper plate 216 is rotated so that one side of the bristles faces the inner wall of the dry powder box 21, and the fixed slot 217 provided on the other side of the scraper plate 216 is clamped into the fixed clip 215 to fix the position of the scraper plate 216. At this time, the rotating mounting turntable 25 will drive the scraper plate 216 provided at one end of the cam rod 26 to clean the inner wall of the dry powder box 21 during the rotation process, and sweep the medicine or powder residue attached to the inner wall of the dry powder box 21 to fall down, and the screw 27 will perform the final push, and at the same time complete the preliminary cleaning of the dry powder box 21.

[0030] Working principle: Before adding medicine, the staff will first remove the box cover 24, pour in a specified amount of flocculant (PAM), and then re-lock the box cover 24 on the top of the dry powder box 21, start the drive motor 218, and the drive motor 218 will drive the main gear 219 fixedly connected to the output end to rotate. The rotating main gear 219 will drive the mounting turntable 25 fixedly connected to the middle of one end and the sub-gear 220 meshing at the bottom to rotate synchronously. The rotating sub-gear 220 will drive the screw 27 fixedly connected to one end to rotate. The rotating mounting turntable 25 will drive the cam rod 26 at one end to make a circular track along the trajectory of the adjusting gear ring 28. The movement of the cam rod 26 will flip the flocculant during the movement to prevent the flocculants from sticking together in a relatively high temperature environment. When the cam rod 26 moves to the oblique upper part of the vibrating particle board 29, the tooth groove provided below the adjusting gear ring 28 will push the meshing cam rod 26 to rotate 180 degrees counterclockwise. When the rotating cam rod 26 contacts the surface of the vibrating particle board 29 at the raised position, it will push one end of the vibrating particle board 29 in contact below to rotate downward under the restriction of the connecting swivel 211, driving the other side of the vibrating particle board 29 to tilt upward. At the same time, the rotating cam rod 26 will The cam rod 26 is rolled to disperse it. When the raised position of the cam rod 26 is separated from the surface of the vibrating particle board 29, the spring provided under the vibrating particle board 29 generates a rebound force when the vibrating particle board 29 loses its pushing force, which drives the vibrating particle board 29 to rotate upward in the opposite direction, reopening the gap and generating vibration at the same time. The dispersed flocculant falls into the bottom of the vibrating particle board 29 along the opened gap. When the cam rod 26 moves to the front side above the vibrating particle board 29, the cam rod 26 pushes the vibrating particle board 29 in the same way. When the vibrating particle board 29 rotates first, it will push the first vibrating particle board 29 that falls into the vibrating particle board 29 when it vibrates. The flocculant material blocks between the material plate 29 and the inner wall of the dry powder box 21 are squeezed and crushed. The extruded and crushed flocculant particles will slide to the outside of the screw 27, and the screw 27 will push and release the flocculant particles in contact. During the pushing and releasing process, the powder residue mixed in the flocculant will pass through the filter plate provided above the vibrating particle board 29 and fall onto the drainage inclined plate 212 provided on the inner side of the vibrating particle board 29. When the vibrating particle board 29 vibrates, the flocculant powder residue will slide along the drainage inclined plate 212 to the pipe opening of the drug delivery tube 23 under the drive of the vibration force, and then fall into the dosing port provided at the bottom of one end of the drug delivery tube 23.

[0031] When the drug addition reaches the end, the staff manually pulls the positioning frame 214 so that the positioning frame 214 slides out of the storage cavity 213 provided on the inner side of the cam rod 26 by half, and then rotates the scraper plate 216 so that the bristle side faces the inner wall of the dry powder box 21, and the fixed slot 217 provided on the other side of the scraper plate 216 is clamped on the fixed clamp 215 to fix the position of the scraper plate 216. At this time, the rotating mounting turntable 25 will drive the cam rod 26 to rotate. The scraper 216 provided at one end of the rod 26 cleans the inner wall of the dry powder box 21, sweeps the medicine or powder residue attached to the inner wall of the dry powder box 21 to the outside of the screw 27, and is pushed by the screw. The powder residue falls onto the drainage inclined plate 212 provided on the inner side of the vibrating particle board 29 under the drive of the scraper 216. The drainage inclined plate 212 drains the medicine and concentrates it into the pipe mouth of the medicine delivery tube 23, and slides into the medicine adding port along the inclined angle of the inner bottom end of the medicine delivery tube 23.
