[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figure 1-Figure 6 An automatic dosing device for sewage treatment comprises four support blocks 2 installed at the four corners of the outer wall of a sewage pool 1, a forward and backward moving mechanism is connected between the four support blocks 2, a U-shaped rod 6 is connected to the outer wall of the forward and backward moving mechanism, a moving groove 601 is penetrated through the upper surface of the middle part of the U-shaped rod 6, a support seat 18 is slidably connected to the inner wall of the moving groove 601, the upper surface of the support seat 18 is fixedly connected and communicated with a medicine box 10, a stirring assembly is connected to the bottom surface of the support seat 18, a slider 19 is fixedly connected to one side of the support seat 18, both ends of the outer wall of the U-shaped rod 6 are fixedly connected to connecting blocks 7, a left and right moving mechanism is connected between the two connecting blocks 7, and the outer wall of the left and right moving mechanism is connected to the slider 19.

[0024] The automatic dosing device for sewage treatment in the utility model is similar in structure to the existing automatic dosing device for sewage treatment, such as a dosing device for sewage pool disclosed in patent publication number CN219950640U. Figures 1 to 6 As shown, when the automatic dosing device for sewage treatment in the utility model is used, the medicine liquid that needs to be added to the inside of the sewage pool 1 is first added to the medicine box 10, and then the front-to-back moving mechanism and the left-to-right moving mechanism are turned on. After the front-to-back moving mechanism is started, the U-shaped rod 6 can be driven to move back and forth above the sewage pool 1. While the U-shaped rod 6 moves back and forth, due to the action of the left-to-right moving mechanism, the medicine box 10 located above the U-shaped rod 6 will also be driven to move back and forth above the sewage pool 1. When the left-to-right moving mechanism is started, the stirring component located under the support seat 18 will be driven to stir the sewage inside the sewage pool 1, so that the medicine liquid inside the sewage pool 1 is more dispersed and uniform, thereby improving the sewage treatment effect and efficiency.

[0025] It should be noted that a metering pump or a common liquid extraction pump is provided inside the medicine box 10, which is prior art and will not be described in detail.

[0026] like Figure 1-Figure 6 As shown, the stirring assembly includes an outer tube 11, an inner tube 12, a rotating assembly and two groups of stirring blades 13. A plurality of medicine outlet holes 1201 are formed through the outer wall of the lower end of the inner tube 12. The rotating assembly is connected to the upper ends of the outer tube 11 and the inner tube 12. The outer tube 11 is sleeved on the outer wall of the inner tube 12. The upper end of the inner tube 12 is fixedly connected to the bottom surface of the support seat 18, and the plurality of medicine outlet holes 1201 are communicated with the inside of the support seat 18. The two groups of stirring blades 13 are fixedly connected to the lower ends of the outer tube 11 and the inner tube 12, respectively.

[0027] More specifically, when the left-right moving mechanism is started, the slider 19 will drive the support seat 18 to move left-right in the moving groove 601, and while the support seat 18 is moving, it will drive the rotating component to rotate in the opposite direction, and after the rotating component rotates in the opposite direction, it will drive the outer tube 11 and the inner tube 12 to rotate in the opposite direction, and while the outer tube 11 and the inner tube 12 are rotating in the opposite direction, the two sets of stirring blades 13 located at the lower ends of the outer tube 11 and the inner tube 12 will stir and mix the sewage inside the sewage pool 1 and the liquid medicine output from the medicine outlet 1201, so as to achieve the purpose and effect of more uniform mixing.

[0028] like Figure 2 and Figure 4 As shown, the rotating assembly includes a No. 1 rack 14, a No. 2 rack 15, a No. 1 gear 16 and a No. 2 gear 17. Both ends of the No. 1 rack 14 and the No. 2 rack 15 are fixedly connected to the outer wall on the inner side of the U-shaped rod 6. The No. 1 gear 16 is sleeved and fixedly connected to the upper end of the outer tube 11. The No. 2 gear 17 is sleeved and fixedly connected to the upper end of the inner tube 12. The No. 1 rack 14 is meshed with the No. 1 gear 16. The No. 2 rack 15 is meshed with the No. 2 gear 17. The upper surface of the No. 2 gear 17 is connected to the bottom surface of the support seat 18. The bottom surface of the No. 2 gear 17 is connected to the upper surface of the No. 1 rack 14.

[0029] More specifically, when the support base 18 moves, it will drive the No. 1 gear 16 and the No. 2 gear 17 connected below to engage with the No. 1 rack 14 and the No. 2 rack 15 respectively. Because the No. 1 rack 14 and the No. 2 rack 15 are respectively located on both sides of the U-shaped rod 6, the No. 1 gear 16 and the No. 2 gear 17 will rotate in the opposite direction when engaged, which can drive the outer tube 11 and the inner tube 12 located below the No. 1 gear 16 and the No. 2 gear 17 to rotate in the opposite direction.

[0030] like Figure 5 and Figure 6 As shown, the bottom surfaces of the support seat 18 and the second gear 17 are both provided with an anti-slip cavity 1801, and the upper surfaces of the first gear 16 and the second gear 17 are both fixedly connected with anti-slip rings 20, and the two anti-slip rings 20 are rotatably connected to the inner walls of the two anti-slip cavities 1801 respectively.

[0031] More specifically, by providing the anti-dropout cavity 1801 and the anti-dropout ring 20 , the first gear 16 and the second gear 17 can be prevented from falling off the support seat 18 and the second gear 17 while ensuring that they can rotate normally.

[0032] like Figure 1 As shown, the front-to-back moving mechanism includes a front-to-back motor 3, a front-to-back reciprocating screw rod 4 and an auxiliary sliding rod 5. The outer wall of the front-to-back motor 3 is fixedly connected to the side wall of one of the support blocks 2, the output shaft of the front-to-back motor 3 is fixedly connected to one end of the front-to-back reciprocating screw rod 4, the other end of the front-to-back reciprocating screw rod 4 passes through one end of a U-shaped rod 6 and two support blocks 2, and is rotatably connected to the inner walls of the two passed support blocks 2, the auxiliary sliding rod 5 is arranged parallel to the front-to-back reciprocating screw rod 4, the auxiliary sliding rod 5 is fixedly connected to the inner walls of the other two support blocks 2, the front-to-back reciprocating screw rod 4 is threadedly connected to the penetration point of the U-shaped rod 6, and the auxiliary sliding rod 5 is slidably connected to the inner wall of the other end of the U-shaped rod 6.

[0033] More specifically, when it is necessary to control the medicine box 10 to move back and forth on the sewage pool 1, it is only necessary to turn on the front and rear motors 3. After the front and rear motors 3 are started, the output shaft can drive the front and rear reciprocating screw rod 4 to rotate. After the front and rear reciprocating screw rod 4 rotates, it can drive the U-shaped rod 6 with a threaded connection on the surface to move back and forth above the sewage pool 1, thereby driving the medicine box 10 on the U-shaped rod 6 to move back and forth.

[0034] like Figure 1-Figure 4 As shown, the left and right moving mechanism includes left and right motors 8 and left and right reciprocating screws 9. The outer walls of the left and right motors 8 are fixedly connected to the side walls of one of the connecting blocks 7. The output shafts of the left and right motors 8 are fixedly connected to one end of the left and right reciprocating screws 9. The other ends of the left and right reciprocating screws 9 penetrate the slider 19 and the two connecting blocks 7, and are rotatably connected to the penetration points of the two connecting blocks 7. The left and right reciprocating screws 9 are threadedly connected to the penetration points of the slider 19.

[0035] More specifically, when the medicine box 10 needs to be controlled to move left and right on the sewage pool 1, it is only necessary to turn on the left and right motors 8. After the left and right motors 8 are started, the output shaft can drive the left and right reciprocating screws 9 to rotate. After the left and right reciprocating screws 9 rotate, the slider 19 connected with the thread on the surface can be driven to move left and right in the moving groove 601, thereby driving the medicine box 10 on the support seat 18 to move forward and backward.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
