Utility Model Content

[0005] The utility model aims to solve the problem in the prior art that when workers add materials to the feeding port of the polyaluminium chloride doser, they find that because the feeding port of the polyaluminium chloride doser is small, tools need to be used for filling.

If the force is too small, the external water pipe is easy to be separated from the water outlet pipe and the water inlet pipe, affecting the use. When the external water pipe needs to be connected to the water outlet pipe and the water inlet pipe, the water pipe is connected through the connecting clamp and the fixing The clamp is connected to the water outlet pipe and the water inlet pipe, and the connecting clamp is rotated by rotating the rotating rod in the fixed block, the limit block on the connecting clamp is fitted with the connecting plate on the fixed clamp, a contact plate is taken to fit with the water pipe, and the screw is rotated in the connecting plate and the limit block to make the screw contact with the inner wall of the contact plate, so that the contact plate can be driven by the screw to squeeze the water pipe, so that the water pipe can be fixed to the surface of the water outlet pipe and the water inlet pipe through the contact plate, and the water pipe can be quickly connected to the water outlet pipe and the water inlet pipe, and the connection effect is relatively stable.

However, when workers add materials to the feeding port 14, they find that because the feeding port 14 is small, tools are needed for filling. The polyaluminium chloride needs to be put into the feeding port 14 too frequently to complete the filling. Frequent filling will cause fatigue of the workers. When adding polyaluminium chloride to the feeding port 14, the fixing rod 207 is taken out from the limiting hole 206, and then the motor 204 is started. The movement of the motor 204 will drive the gear 205 to move, so that the gear 205 can drive the rack 203 to slide in the adjusting block 201, and the connecting hole 202 provided on the rack 203 overlaps with the connecting hole 202 on the adjusting block 201.

One end of the fixed rod 207 is fixedly connected to a guide block 213, and the cross section of the guide block 213 is arc-shaped.When the fixing rod 207 is connected to the limiting hole 206, the guide block 213 installed on the fixing rod 207 can increase the speed of connecting the fixing rod 207 and the limiting hole 206, thereby improving the connection efficiency. The inner wall of the fixing rod 207 is rotatably connected with a pull ring 212. When the fixing rod 207 needs to be pulled out of the limiting hole 206, the pull ring 212 installed in the fixing rod 207 can be used to pull the fixing rod 207 out of the limiting hole 206. The pull ring 212 can increase the speed of pulling the fixing rod 207.

[0037] In the embodiments of the present invention, please refer to Figures 6 to 9The auxiliary device 3 includes a fixed plate 301, which is fixedly connected to the body 11. A support rod 302 is fixedly connected to the side of the fixed plate 301 away from the body 11. A fixed clamp 303 is fixedly connected to one end of the support rod 302 away from the fixed plate 301. One end of the fixed clamp 303 is fixedly connected to a fixed block 304. A rotating rod 305 is rotatably connected to the inner wall of the fixed block 304. Both ends of the arc surface of the rotating rod 305 are fixedly connected to the same connecting clamp 306. The other end of the fixed clamp 303 is fixedly connected to a connecting plate 308. An end of the connecting clamp 306 close to the connecting plate 308 is fixedly connected to a limiting block 307. The limiting block 307 and the connecting plate 308 are fixedly connected. The inner wall thread of 8 is penetrated by the same screw rod 309, and one end of the screw rod 309 close to the fixed block 304 is movably connected with a contact plate 310. When the water outlet pipe 12 and the water inlet pipe 13 are in use, they are connected to an external water pipe to facilitate the work of the water outlet pipe 12 and the water inlet pipe 13. However, the external water pipe is generally connected with an iron wire. When the external water pipe is connected with the water outlet pipe 12 and the water inlet pipe 13, twisting the iron wire too hard will cause the surface of the water outlet pipe 12 and the water inlet pipe 13 to deform. If the force is too small, the external water pipe is easy to be separated from the water outlet pipe 12 and the water inlet pipe 13, affecting the use. When it is necessary to connect the external water pipe with the water outlet pipe 12 and the water inlet pipe 13, the water pipe The outlet pipe 12 and the inlet pipe 13 are connected by connecting the clamp 306 and the fixed clamp 303, and the connecting clamp 306 is rotated by rotating the rotating rod 305 in the fixed block 304, and the limit block 307 on the connecting clamp 306 is fitted with the connecting plate 308 on the fixed clamp 303, and a contact plate 310 is taken to fit with the water pipe, and the screw 309 is rotated in the connecting plate 308 and the limit block 307, so that the screw 309 is in contact with the inner wall of the contact plate 310, so that the contact plate 310 can be driven by the screw 309 to squeeze the water pipe, so that the water pipe can be fixed on the surface of the outlet pipe 12 and the inlet pipe 13 through the contact plate 310, and the water pipe can be quickly It is connected to the water outlet pipe 12 and the water inlet pipe 13, and the connection effect is relatively stable. The arc surface of the screw 309 is fixedly connected to the end away from the contact plate 310 with a turntable 311. When the screw 309 needs to be rotated and the contact plate 310 is driven by the screw 309 to extrude the water pipe, the screw 309 can be rotated by using the turntable 311 installed on the screw 309. The turntable 311 can increase the speed of the contact plate 310 moving through the screw 309. The rotating rod 305 is made of titanium alloy. The surface of the rod body of the rotating rod 305 made of titanium alloy is relatively hard. This is also why the surface of the rod body of the rotating rod 305 is less likely to deform under long-term use and has a longer service life.

[0038] The working principle of a polyaluminium chloride doser provided by the utility model is as follows: when polyaluminium chloride needs to be added to the feeding port 14, the fixing rod 207 is taken out from the limiting hole 206, and then the motor 204 is started. The movement of the motor 204 drives the gear 205 to move, so that the gear 205 can drive the rack 203 to slide in the adjusting block 201, and the connecting hole 202 provided on the rack 203 overlaps with the connecting hole 202 on the adjusting block 201 at an angle, and the fixing rod 207 is connected to another limiting hole 206, so that the rack 203 can be fixed. At this time, the polyaluminium chloride in the storage bin 209 will flow into the feeding port 14 as the two connecting holes 202 overlap, so that the filling can be completed. The worker can observe the filling of polyaluminium chloride into the feeding port 14 through the storage bin 209. After the filling is completed, the cover plate 202 on the storage bin 209 can be opened. 10 is unscrewed, and the storage bin 209 can be filled by opening the cover plate 210. The use of the adjusting device 2 can facilitate the filling of polyaluminium chloride into the feeding port 14, thereby improving the efficiency of filling polyaluminium chloride. When the user needs to add polyaluminium chloride to the storage bin 209, the polyaluminium chloride in the storage bin 209 can be judged according to the scale 211 installed on the storage bin 209, thereby facilitating the addition of polyaluminium chloride to the storage bin 209. When the fixing rod 207 is connected to the limiting hole 206, the guide block 213 installed on the fixing rod 207 can increase the speed of connection between the fixing rod 207 and the limiting hole 206, thereby improving the connection efficiency. When the fixing rod 207 needs to be pulled out of the limiting hole 206, the pull ring 212 installed in the fixing rod 207 can be used to pull the fixing rod 207 out of the limiting hole 206, and the pull ring 212 can increase the speed of pulling the fixing rod 207.

[0039] When it is necessary to connect the external water pipe with the water outlet pipe 12 and the water inlet pipe 13, the water pipe is connected with the water outlet pipe 12 and the water inlet pipe 13 through the connecting clamp 306 and the fixed clamp 303, the connecting clamp 306 is rotated by rotating the rotating rod 305 in the fixed block 304, the limiting block 307 on the connecting clamp 306 is fitted with the connecting plate 308 on the fixed clamp 303, a contact plate 310 is taken to fit with the water pipe, the screw 309 is rotated in the connecting plate 308 and the limiting block 307, and the screw 309 is brought into contact with the inner wall of the contact plate 310, so that the contact plate 310 can be driven by the screw 309 to squeeze the water pipe. Therefore, the water pipe can be fixed on the surface of the water outlet pipe 12 and the water inlet pipe 13 through the contact plate 310, and the water pipe can be quickly connected to the water outlet pipe 12 and the water inlet pipe 13, and the connection effect is relatively stable. When the screw 309 needs to be rotated and the contact plate 310 is driven by the screw 309 to squeeze the water pipe, the screw 309 can be rotated by using the turntable 311 installed on the screw 309. The turntable 311 can increase the speed of the contact plate 310 moving through the screw 309. The surface of the rotating rod 305 made of titanium alloy is relatively hard. This is also why the surface of the rotating rod 305 is less likely to deform after long-term use, and has a longer service life.
