Description

Technical Field

[0001] The utility model relates to the technical field of waste liquid treatment, in particular to a feeding device for a waste liquid treatment pool. Background Art

[0002] Waste liquid treatment includes physical precipitation, flocculation precipitation, filtration, neutralization reaction, redox reaction, microbial degradation and other treatment methods. For neutralization reaction, redox reaction, etc., it is necessary to add a certain amount of chemical reagents to the waste liquid treatment pool, and then use a stirring device to fully mix the chemical reagents and waste liquid for reaction. When adding chemical reagents, if a manual method is used, the efficiency is low. In order to solve this problem, there are also some feeding devices in the prior art that can automatically add chemical reagents to the waste liquid treatment pool, but these feeding devices all add chemical reagents continuously until the required amount of chemical reagents is added, which leads to excessive concentration of local chemical reagents in the waste liquid treatment pool. Utility Model Content

[0003] In order to solve the deficiencies of the prior art, the utility model provides a feeding device for a waste liquid treatment pool, which can intermittently add chemical reagents.

[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0016] like Figure 1 As shown, this embodiment provides a feeding device for a waste liquid treatment tank, comprising a waste liquid treatment tank 1 and a feeding mechanism 2 mounted above the waste liquid treatment tank 1 .

[0017] like Figure 1 , Figure 2As shown, the feeding mechanism 2 includes a motor 21, a material box 22, a turntable 23 and an adjustment control unit. The motor 21 is arranged on the first support frame 41, and the output shaft of the motor 21 is used to drive the turntable 23. The material box 22 is arranged on the second support frame. The material box 22 faces the bottom discharge port on one side of the turntable 23. A sealing plate 221 is provided at the discharge port. The top of the sealing plate 221 is hinged to the material box 22. The adjustment control unit is used to control the opening and closing of the sealing plate 221, thereby controlling the opening or closing of the discharge port. The adjustment control unit includes a control plate 24 and two connecting plates. The top of the control plate 24 It is rotatably connected to the turntable 23. Note that the control plate 24 is not connected to the center of the turntable 23, but to an eccentric position. The first connecting plate 251 and the second connecting plate 252 are respectively arranged on both sides of the control plate 24. The opposite ends of the first connecting plate 251 and the second connecting plate 252 are both rotatably connected to the control plate 24. A convex plate 222 is provided at the bottom of one end of the sealing plate 221. The other end of the first connecting plate 251 is rotatably connected to the convex plate 222. The other end of the second connecting plate 252 is rotatably connected to the third support frame 26. The third support frame 26 is fixedly arranged.

[0018] The material box 22 is used to hold chemical reagents required for waste liquid treatment. When multiple chemical reagents need to be added, a plurality of partitions 223 can be vertically arranged in the material box 22, and each grid holds different chemical reagents.

[0019] The usage principle is as follows: Figure 2 From the perspective, at this time, the regulating plate 24 is in a vertical state and in the highest position, the first connecting plate 251 and the second connecting plate 252 are both in a horizontal state, and the sealing plate 221 is in a closed state; since the third support frame 26 is fixed, the second connecting plate 252 can only rotate in the circumferential direction at its right end, so when the motor 21 is used to rotate the turntable 23 clockwise, the bottom end of the regulating plate 24 will deviate to the lower right, thereby causing the right end of the first connecting plate 251 to deviate to the lower right, thereby pulling open the sealing plate 221 and adding chemical reagents into the waste liquid treatment tank 1; when the turntable 23 rotates one circle, it returns to the Figure 2 In the state of , the sealing plate 221 closes the discharge port again.

[0020] Furthermore, the feeding device also includes a stirring mechanism 3, such as Figure 3 , Figure 4 As shown, the stirring mechanism 3 includes a stirring paddle 31, two bevel gears 32, a driving gear 33 and a driven gear 34. A horizontal rod 42 is fixedly provided on the first support frame 41. The first support frame 41 is also rotatably provided with a second rotating rod 44. The rod body of the stirring paddle 31 is rotatably connected to the horizontal rod 42. The two bevel gears 32 are meshed, one of the bevel gears 32 is coaxially arranged on the top of the rod body of the stirring paddle 31, and the other bevel gear 32 and the driving gear 33 are coaxially arranged on the first rotating rod 43. The output shaft of the motor 21 passes through the first support frame 41 and is connected to the first rotating rod 43. The driving gear 33 is meshed with the driven gear 34, and the driven gear 34 and the turntable 23 are coaxially arranged on the second rotating rod 44.

[0021] The operating principle is as follows: the output shaft of the motor 21 drives the first rotating rod 43 counterclockwise, so that the bevel gear 32 and the driving gear 33 on the first rotating rod 43 rotate counterclockwise at the same time. On the one hand, the driving gear 33 drives the driven gear 34 to rotate, and then drives the rotating disk 23 to rotate clockwise, thereby controlling the opening and closing of the sealing plate 221. On the other hand, since the two bevel gears 32 are engaged, the stirring paddle 31 is driven to start stirring. That is to say, this embodiment can add materials and stir at the same time through a power source of the motor 21, and stir the waste liquid while adding materials.

[0022] In order to leave more operation time for stirring and improve the stirring effect, it is possible to consider extending the closing time of the sealing plate 221. The present embodiment adopts the following measures: the driving gear 33 is provided with a sawtooth section and a smooth section. When the sawtooth section is meshed with the driven gear 34, it is used to make the driven gear 34 rotate one circle. Figure 2 , Figure 4 From the perspective, the sealing plate 221 is in a closed state at this time, and the driven gear 34 has just separated from the serrated section of the driving gear 33 and is located in the smooth section. Therefore, when the motor 21 continues to drive the first rotating rod 43 counterclockwise, the stirring paddle 31 will continue to rotate without causing the driven gear 34 to rotate. The sealing plate 221 is always in a closed state until the serrated section of the driving gear 33 meshes with the driven gear 34, and then the sealing plate 221 will be opened.

[0023] The above embodiments are only used to illustrate the technical ideas and features of the utility model, and are not intended to be the only or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
