[0032] Now, the present utility model will be further described in detail with reference to the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0033] Figure 1 A cyclic waste water treatment reagent automatic dosing device in the present utility model is shown. The device includes: a bracket 1, a reagent tank 2 arranged on the bracket 1, a first dosing structure 3 arranged inside the reagent tank 2, and a second dosing structure 4 arranged at the bottom of the reagent tank 2; several universal wheels 6 are arranged at the bottom of the bracket 1.

[0034] As Figure 2 shown, the device adopts a double dosing mode of a rotating structure 31 and a reciprocating structure 41, which can realize the uniform mixing and uniform dosing of the reagent in the vacuum waste water, and the dosing amount is controllable, so as to more efficiently carry out waste water treatment. The rotating structure 31 realizes the rapid and uniform sprinkling of the reagent into the waste water through a plurality of first medicine dosing tanks 32 fixed on the rotating curved plate 313; the second medicine dosing tank 42 of the reciprocating structure 41 accurately controls the dosing amount by reciprocating movement, effectively improving the treatment efficiency.

[0035] A connecting pipe 5 is arranged on one side of the reagent tank 2, and the reagent tank 2 is connected to a waste water storage tank through the connecting pipe 5.

[0036] As Figure 3 shown, the first dosing structure 3 includes: a rotating structure 31 arranged inside the reagent tank 2, and several first medicine dosing tanks 32 arranged on the rotating structure 31; the rotating structure 31 includes: several connecting rods 311 penetrating through the reagent tank 2, several fixed connecting plates 312 fixedly connected to the connecting rods 311, and a rotating curved plate 313 arranged between the several fixed connecting plates 312.

[0037] Several bumps 314 are arranged at both ends of the rotating curved plate 313. One end of the bump 314 is connected to the rotating curved plate 313, and the other end is connected to the fixed connecting plate 312. Several rotating motors are arranged on the outer wall of the reagent tank 2, and the rotating motors are connected to the rotating structure 31.

[0038] The rotary structure 31 drives the reciprocating structure 41 by adopting a gear mechanism, realizing the automatic control of the reciprocating motion. Without manual timing for dosing, it can operate stably for a long time. By arranging a plurality of quantitative first dosing tanks 32 on the rotary curved plate 313, the medicament can be quickly and evenly sprinkled into the wastewater. Due to the revolution of the rotary curved plate 313, the medicament can form a swirling force to enter the wastewater, enabling the medicament to be more fully blended and mixed in the wastewater, and improving the coverage rate.

[0039] As shown in the figure, the second dosing structure 4 includes: a reciprocating structure 41 arranged at the bottom of the medicament tank 2, and a second dosing tank 42 arranged on the reciprocating structure 41; the reciprocating structure 41 includes: a reciprocating rod 411 arranged on the inner wall of the bottom of the medicament tank 2, a rack 412 arranged on the reciprocating rod 411, a gear member 413 meshed with the rack 412, and a reciprocating wheel 414 slidably connected to the gear member 413; a plurality of rotary motors are arranged on the outer wall of the medicament tank 2, and the rotary motors are connected to the rotary structure 31; the reciprocating rod 411 is connected to the medicament tank 2 through a plurality of fixing members 415.

[0040] A plurality of dosing holes are arranged on the first dosing tank 32 and the second dosing tank 42.

[0041] The gear member 413 includes: a half gear 4131 meshed with the rack 412, a plurality of sliding rods 4132 fixedly connected to the half gear 4131, and a slider 4133 sleeved on the sliding rods 4132; the slider 4133 is arranged on the outer edge of the reciprocating wheel 414, and the second dosing tank 42 is arranged on the reciprocating wheel 414.

[0042] In the reciprocating structure 41, the meshing of the half gear 4131 and the rack 412 enables the reciprocating rod 411 to obtain a periodic reciprocating motion. By arranging the slider 4133 on the outer edge of the reciprocating wheel 414, the reciprocating motion is transformed into continuous rotation, driving the second dosing tank 42 to achieve automatic and quantitative dosing, avoiding manual errors and processing more efficiently. The second dosing tank 42 adopting the reciprocating structure 41 realizes precise quantitative dosing of the medicament by controlling the reciprocating motion.

[0043] Compared with using only the rotary structure 31, the reciprocating dosing can redistribute the medicament in a specific area, effectively making up for the dead corners that are difficult to reach by the rotary structure 31. The two complement each other, making the medicament more evenly distributed in the wastewater, thereby improving the treatment efficiency.

[0044] When the utility model is in use, the device is installed at the location where the wastewater needs to be treated, and the medicament tank 2 is connected to the wastewater storage tank through the connecting pipe 5; the rotary motor arranged on the outer wall of the medicament tank 2 is turned on to drive the rotary structure 31 to start rotating; the rotary structure 31 drives the medicament in the first dosing tank 32 to be put into the wastewater storage tank.

[0045] Meanwhile, the semi-gear 4131 in the gear member 413 meshes and rotates with the rack 412, driving the sliding rod 4132 and the slider 4133 to reciprocate. The reciprocating structure 41 drives the medicament in the second dosing tank 42 to be intermittently discharged into the wastewater storage tank; when the specified dose of the medicament is completely discharged into the wastewater storage tank, the rotating motor and the reciprocating mechanism automatically shut down and stop working.

[0046] The whole device is pushed by the universal wheels 6 to move to the next location to be treated, and the above-mentioned use steps are repeated to treat more wastewater.

[0047] Based on the ideal embodiments of the present invention as inspiration, through the above description, relevant personnel can completely make various changes and modifications without departing from the technical idea of the present invention. The technical scope of the present invention is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
