DETAILED DESCRIPTION

[0019] The specific embodiments of the utility model are further described in detail below. Figures 1-5 The specific embodiments of the utility model are further described in detail below.

[0020] The technical solutions solved by example one are as follows: in use, the mixing tank 1 is provided with a stirring device 3 which can mix medicaments through a stirring rod 19 cooperating with a stirring shaft 18; an aeration device is provided to aerate the mixed liquid in the mixing tank 1 through an aeration pipe 12, further dispersing and homogenizing the liquid medicine, and ensuring the mixing effect of the medicaments; a screw rod 9 cooperates with a driving motor 13 to drive the cross rod 10 to move upward along the vertical rod 7, and then drive the aeration pipe 12 connected to the cross rod 10 through a clamping piece 11 to extend upward through the manhole 4, so that the operator can disassemble and connect the components such as the aeration pipe 12 and the clamping piece 11 through the manhole 4; the feeding device 2 is used to store different medicaments, and the metering pump 23 can quantitatively provide the liquid medicine to the mixing tank 1, so that different liquid medicines can enter the mixing tank 1 according to the corresponding proportion.

[0021] In example two, on the basis of example one, the feeding device 2 is provided with multiple groups, and the storage tanks 21 of the groups of feeding devices 2 can be used to store different medicaments, such as non-oxidizing algicide, slow-release agent, oxidizing algicide, and dispersing agent. Only two groups of feeding devices 2 are drawn in the utility model drawings, and the medicaments can be added to the storage tanks 21 through the feeding pipes 22. When the medicaments are mixed and configured, the booster pump 25 and the metering pump 23 are opened, the metering pump 23 guides the medicaments of the corresponding proportion from the storage tanks 21, and then the medicaments enter the booster pump 25 after being pressurized, and the medicaments are transported upward to the mixing tank 1 through the liquid supply pipe 26 under the action of the booster pump 25.

[0022] The aeration pipe 12 is evenly provided with a plurality of aeration holes on the outer edge. The upper end of the aeration pipe 12 is an inlet end and can be connected with a blower. The blower and the connection between the blower and the aeration pipe 12 are prior art and will not be described in detail. Under the action of the blower, the aeration pipe 12 can aerate the mixture tank 1, so as to uniformly disperse the medicament and facilitate mixing of the medicament. In addition, the stirring motor 20 can drive the stirring shaft 18 to rotate, and the stirring rod 19 can cooperate to stir and mix the medicament. After the medicament is uniformly mixed, the discharge valve 6 can be opened, and the uniformly mixed medicament is discharged to the circulating water through the discharge pipe 5 to treat the circulating water.

[0023] In example three, on the basis of example two, the aeration pipe 12 needs to be regularly maintained during use, so the maintenance hole 4 is provided. Opening the maintenance cover 14 of the maintenance hole 4 can facilitate maintenance of the aeration pipe 12. Further, in order to facilitate maintenance of the aeration pipe 12, the driving motor 13 is provided. The driving motor 13 drives the screw rod 9 connected to the connecting rod 8 and the mixture tank 1 to rotate in a forward direction. The screw rod 9 drives the horizontal rod 10 to move upward along the vertical rod 7. The clamping piece 11 and the aeration pipe 12 also move upward. The aeration pipe 12 extends out of the maintenance hole 4, and the clamping piece 11 also approaches the maintenance hole 4, so as to facilitate disassembly of the clamping piece 11 and the aeration pipe 12 for maintenance. The clamping piece 11 is connected by the arc-shaped front clamping piece 16 and the arc-shaped rear clamping piece 15 through the bolt 17, which is convenient to disassemble. Opening the observation cover 28 of the storage tank 21 can observe the situation in the storage tank 21 through the observation hole 27.
