Description

Technical Field

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

[0002] Waste liquid treatment methods include physical, biological, and chemical treatment methods. For biological treatment methods, it is sometimes necessary to carry out the treatment in a sealed waste liquid treatment tank. The reasons are: ① The sealed waste liquid treatment tank can better control the pH value, temperature, oxygen content and other conditions; ② Malodorous gases or harmful substances will be produced during the waste liquid treatment process. The sealed waste liquid treatment tank can effectively collect and treat these pollutants to prevent them from spreading to the surrounding environment.

[0003] When treating waste liquid, a stirring paddle is also required to fully mix the reagent with the waste liquid. If the stirring paddle is fixed in the waste liquid treatment tank, it will be inconvenient to clean the inner wall of the waste liquid treatment tank later. In order to solve this problem, the stirring paddle can be installed on the lid of the waste liquid treatment tank. When the inner wall of the tank needs to be cleaned, the lid and the stirring paddle are raised by the lifting mechanism. However, this solution still has problems: ① The lid and the stirring paddle need to be raised to a relatively high position. If the stirring paddle is too low, the stirring paddle may scratch the staff when they clean the inner wall of the tank; ② The general lifting mechanism can only move the lid and the stirring paddle vertically, that is, when the staff cleans the inner wall of the tank, the stirring paddle is directly above the staff, which poses a great safety hazard. Utility Model Content

[0004] In order to solve the deficiencies of the prior art, the utility model provides a stirring device for a waste liquid treatment tank, which can make a stirring paddle deviate from the waste liquid treatment tank.

[0005] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0006] A waste liquid treatment tank stirring device comprises a waste liquid treatment tank and a lifting and transferring mechanism.

[0007] The lifting and transferring mechanism is arranged on the outside of the waste liquid treatment tank, and includes a cover, a column, a screw, a first motor, a sleeve and a slider. The column is arranged on the top of the base, and the interior of the column is hollow. The side wall thereof is provided with a vertical first through groove, and a horizontal second through groove is provided on one side of the top of the first through groove. The screw is rotatably arranged in the column, the first motor is arranged in the base, and the output shaft at the top of the first motor is connected to the screw, the slider is slidably arranged in the column and threadedly engaged with the screw, the sleeve is slidably engaged with the outer wall of the column, the slider and the sleeve are fixedly connected by an L-shaped plate, and the horizontal section of the L-shaped plate is slidably arranged in the first through groove, the cover is arranged on the top of the waste liquid treatment tank, the cover is connected to the sleeve through a cantilever, and a stirring paddle is provided at the bottom of the cover.

[0008] Furthermore, when the L-shaped plate cross section moves to the second through groove, the stirring paddle is completely separated from the waste liquid treatment tank.

[0009] Furthermore, it also includes a power mechanism, which includes a second motor and three gears, the first gear, the second gear, and the third gear are meshed in sequence, an inverted U-shaped plate is provided on the top of the cover, the U-shaped plate is connected to the cantilever, the first gear and the second gear are both rotatably provided on the top of the cover, the outer edge of the second gear exceeds the outer edge of the cover, the first gear is located below the U-shaped plate, the stirring paddle is coaxially connected to the first gear, the second motor is provided on the support plate, and its top output shaft is connected to the third gear.

[0010] Furthermore, it also includes a scraping assembly, which includes a scraper, a gear ring and a lifting assembly. The gear ring is rotatably arranged on the top of the waste liquid treatment tank and is located below the second gear. The scraper is arranged in the waste liquid treatment tank and is close to the inner wall of the waste liquid treatment tank. The top of the scraper is fixedly connected to the inner wall of the gear ring through a mounting plate. The lifting assembly is arranged on the support plate, which is connected to the second motor and is used to control the height of the second motor so that the third gear is engaged with the gear ring. An avoidance groove is provided at a position corresponding to the mounting plate at the bottom of the cover for avoiding the mounting plate.

[0011] Furthermore, the structure of the lid can be designed according to actual conditions. When the waste liquid treatment tank needs to be closed, the lid is used to close the waste liquid treatment tank. When the waste liquid treatment tank does not need to be closed, the structure of the lid is relatively random.

[0012] The beneficial effect of the utility model is that the lifting and transferring mechanism has an ingenious structure. Through the ingenious cooperation of the column, the screw rod, the sleeve and the slider, the cover and the stirring paddle thereon can be moved upward first, and then rotated horizontally within a certain range to make the stirring paddle deviate from the waste liquid treatment tank, so that the staff can clean the inner wall of the waste liquid treatment tank.

[0017] like Figure 1 As shown, this embodiment provides a waste liquid treatment tank stirring device, including a waste liquid treatment tank 1 and a lifting and transferring mechanism 2.

[0018] Specifically, Figure 1 , Figure 2As shown, the lifting and transferring mechanism 2 is arranged outside the waste liquid treatment tank 1, including a cover 21, a column 22, a screw rod 23, a first motor, a sleeve 25 and a slider 26. The column 22 is vertically arranged on the top of the base 24. The column 22 is hollow inside. The side wall of the column 22 is provided with a vertical first through groove 221. One side of the top of the first through groove 221 is provided with a horizontal second through groove 222. The first through groove 221 and the second through groove 222 form an inverted L shape, and both are connected to the inside of the column 22. The screw rod 23 rotates The first motor is arranged in the column 22, the first motor is arranged in the base 24, the output shaft at the top of the first motor is connected to the screw rod 23, the slider 26 is slidably arranged in the column 22, the slider 26 is threadedly matched with the screw rod 23, the sleeve 25 is slidably matched with the outer wall of the column 22, the slider 26 and the sleeve 25 are fixedly connected by the L-shaped plate 27, the L-shaped plate 27 is horizontally slidably arranged in the first through groove 221, the cover 21 is arranged on the top of the waste liquid treatment tank 1, the cover 21 is connected to the sleeve 25 by a cantilever 28, and a stirring paddle is provided at the bottom of the cover 21.

[0019] The operating principle is as follows: because the slider 26 is threadedly engaged with the screw rod 23, and the L-shaped plate 27 and the slider 26 are restricted by the first through groove 221, the first motor drives the screw rod 23 in the forward direction, which will cause the slider 26 to move upward, thereby causing the L-shaped plate 27, the sleeve 25, the cantilever 28 and the cover 21 connected to the slider 26 to move upward at the same time; when the L-shaped plate 27 moves upward to the same height as the second through groove 222, the stirring paddle is completely separated from the waste liquid treatment tank 1. At this time, the first motor continues to drive the screw rod 23 in the forward direction, and the L-shaped plate 27 loses the restriction of the first through groove 221, so the slider 26 and the L-shaped plate 27 will not move upward again, but rotate with the screw rod 23, thereby causing the stirring paddle to deviate from the waste liquid treatment tank 1; when the stirring paddle needs to be placed back in the waste liquid treatment tank 1, the first motor drives the screw rod 23 in the reverse direction, and the L-shaped plate 27 first separates from the second through groove 222, and then moves downward along the first through groove 221, thereby placing the stirring paddle back in the waste liquid treatment tank 1.

[0020] More specifically, the structure of the lid 21 can be designed according to actual conditions. When the waste liquid treatment tank 1 needs to be closed, the lid 21 is used to close the waste liquid treatment tank 1. When the waste liquid treatment tank 1 does not need to be closed, the structure of the lid 21 is relatively arbitrary.

[0021] More specifically, Figure 3As shown, the stirring device also includes a power mechanism 3 for driving a stirring paddle, and the specific implementation method is as follows: the power mechanism 3 includes a second motor 34 and three gears, and the three gears are a first gear 31, a second gear 32, and a third gear 33, which are meshed in sequence. An inverted U-shaped plate 211 is provided on the top of the cover 21, and the U-shaped plate 211 is connected to the cantilever 28. The first gear 31 and the second gear 32 are both rotatably arranged on the top of the cover 21, and the first gear 31 is located below the U-shaped plate 211. The stirring paddle is coaxially connected to the first gear 31, and the second motor 34 is arranged on the support plate 11. The output shaft at the top of the second motor 34 is connected to the third gear 33. Note: the outer edge of the second gear 32 must exceed the outer edge of the cover 21. The purpose of this design is to prevent the third gear 33 from hindering the cover 21 from being covered on the waste liquid treatment tank 1.

[0022] In order to free up manpower, this embodiment also provides a scraping component for automatically scraping the inner wall of the waste liquid treatment tank 1. The specific implementation method is as follows: Figure 3 , Figure 4 As shown, the scraping assembly includes a scraper 41, a gear ring 43 and a lifting assembly 44. The gear ring 43 is rotatably arranged on the top of the waste liquid treatment tank 1, and the gear ring 43 is located below the second gear 32. The scraper 41 is arranged in the waste liquid treatment tank 1 and is close to the inner wall of the waste liquid treatment tank 1. The top of the scraper 41 is fixedly connected to the inner wall of the gear ring 43 through the mounting plate 42. The lifting assembly 44 is arranged on the support plate 11. The lifting assembly 44 is connected to the second motor 34 to control the height of the second motor 34 so that the third gear 33 is engaged with the gear ring 43. There are many ways to implement the lifting assembly 44, such as using a lifting rod driven by a cylinder, an oil cylinder or a hydraulic pressure. An avoidance groove is provided at the position corresponding to the mounting plate 42 at the bottom of the cover 21 to avoid the mounting plate 42.

[0023] The operating principle is as follows: after taking out the stirring paddle using the lifting and transfer mechanism 2, the lifting assembly 44 is used to move the second motor 34 downward, so that the third gear 33 is engaged with the gear ring 43, and the third gear 33 is driven by the second motor 34, so that the gear ring 43 and the scraper 41 thereon are rotated around the waste liquid treatment tank 1, thereby scraping off impurities adhering to the inner wall of the waste liquid treatment tank 1.

[0024] 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.
