[0026] The following combines Figures 1 to 3 to further describe the present invention:

[0027] An automatic cleaning equipment for the flange of a lithium battery electrolyte ton barrel includes a positioning and rotating mechanism and a cleaning and air-drying mechanism. The positioning and rotating mechanism positions the flange and rotates the flange, and the cleaning and air-drying mechanism cleans and air-dries the outer surface and internal pipeline of the rotating flange. The positioning and rotating mechanism and the cleaning and air-drying mechanism work synchronously.

[0028] As Figure 1 shown, the flange includes a disc 21, a horn tube 22 on the upper surface of the disc 21, and a straight tube 23 on the lower surface of the disc 21. The horn tube 22 communicates with the straight tube 23.

[0029] Figure 1 The large-diameter flange A and the small-diameter flange B only schematically show that the positioning and rotating mechanism can clamp flanges of different diameters. During actual cleaning, only one flange is cleaned.

[0030] The rotating mechanism in the positioning and rotating mechanism includes a driving wheel 12. The edge of the driving wheel 12 is in close contact with the edge of the disc 21 of the flange. The driving wheel 12 is connected to a rotating servo motor 10 through a speed reducer 11. The rotating servo motor 10 rotates the driving wheel 12, and the rotating driving wheel 12 rotates the disc 21 of the flange.

[0031] The positioning mechanism in the positioning and rotating mechanism includes a first positioning wheel 13, a second positioning wheel 14, and a transplanting and positioning cylinder. The first positioning wheel 13 and the second positioning wheel 14 are respectively located on a support bracket and position and clamp the edge of the disc 21 of the flange. The transplanting and positioning cylinder horizontally moves the driving wheel 12 to cooperate with the first positioning wheel 13 and the second positioning wheel 14 to clamp and position discs 21 of different diameters, and enables the disc 21 to rotate. That is, three wheels clamp and position the disc 21, and at the same time, the driving wheel 12 also makes the disc 21 slowly rotate through friction, so that the straight tube 23 at the lower end can be cleaned by the movable cleaning nozzle and air-dried by the movable air-drying nozzle during rotation.

[0032] The transplanting positioning cylinder includes a first transplanting positioning cylinder 15 and a second transplanting positioning cylinder 16. The rotary servo motor 10 is installed on the moving bracket, and the driving wheel 12 is located below the moving bracket. The first transplanting guiding mechanism 17 and the second transplanting guiding mechanism 18 are respectively arranged on both sides of the moving bracket. The cylinder rod of the first transplanting positioning cylinder 15 is connected to the first transplanting guiding mechanism 17, and the cylinder rod of the second transplanting positioning cylinder 16 is connected to the second transplanting guiding mechanism 18. The first transplanting positioning cylinder 15 and the second transplanting positioning cylinder 16 jointly displace the driving wheel 12 in the horizontal direction.

[0033] As Figure 2 shown, the cleaning and air-drying mechanism includes a fixed cleaning nozzle and a fixed air-drying nozzle. There are 2 fixed cleaning nozzles: the first fixed cleaning nozzle 44 and the second fixed cleaning nozzle 45. The first fixed cleaning nozzle 44 is located above the disc 21 to clean the upper surface of the disc 21 and the horn tube 22 on the upper surface of the disc 21. The second fixed cleaning nozzle 45 is located below the disc 21 to clean the lower surface of the disc 21. There are 2 fixed air-drying nozzles: the first fixed air-drying nozzle 31 and the second fixed air-drying nozzle 35. The first fixed air-drying nozzle 31 is located above the disc 21 to air-dry the upper surface of the disc 21 and the horn tube 22 on the upper surface of the disc 21. The second fixed air-drying nozzle 35 is located below the disc 21 to air-dry the lower surface of the disc 21.

[0034] The cleaning and air-drying mechanism further includes a first moving cleaning nozzle 41, a second moving cleaning nozzle 42, a first moving air-drying nozzle 32, and a second moving air-drying nozzle 33. The first moving cleaning nozzle 41, the second moving cleaning nozzle 42, the first moving air-drying nozzle 32, and the second moving air-drying nozzle 33 are installed on the moving slider 37. The vertical lifting cylinder 30 is connected to the moving slider 37, driving the moving slider 37 to move in the vertical direction so that the two moving cleaning nozzles clean the outer wall of the straight pipe 23 of the flange and the two moving air-drying nozzles air-dry the outer wall of the straight pipe 23 of the flange.

[0035] The cleaning and air-drying mechanism further includes an in-pipe cleaning and air-drying mechanism. The elastic and telescopic cleaning pipe is connected to a port of the horn tube 22 through the inner cleaning connection sub-tooth 43 of the flange for cleaning the inner wall of the horn tube 22 and the straight pipe 23. The elastic and telescopic air-drying pipe is connected to the other port of the horn tube 22 through the inner air-drying connection sub-tooth 36 of the flange for air-drying the inner wall of the horn tube 22 and the straight pipe 23.

[0036] Figure 2 There are multiple markings of the first moving cleaning nozzle 41, the second moving cleaning nozzle 42, the first moving air-drying nozzle 32, and the second moving air-drying nozzle 33, just to show the maximum moving range of these nozzles, not that two sets are installed.

[0037] As Figure 3As shown, it also includes a box body 5, in which the positioning and rotating mechanism and the cleaning and drying mechanism are located. A liquid receiving tank is provided at the lower part of the box body, and the liquid receiving tank is provided with an upper liquid level switch and a lower liquid level switch at different heights; the liquid level switch effectively prevents overflow after the liquid receiving tank is full, and the liquid is directly discharged to the corresponding wastewater treatment area through the drainage pipe connected to the bottom of the liquid receiving tank, thereby reducing pollution to the environment around the equipment.

[0038] The working principle of the automatic cleaning equipment for the flange of a lithium battery electrolyte ton barrel of the present invention is as follows: the disc of the flange is placed on a supporting bracket; the disc of the flange is positioned and clamped by a positioning and rotating mechanism; the elastic and retractable cleaning tube and the elastic and retractable air-drying tube are connected to the teeth to clean the flange; the rotary servo motor is started to drive the flange to rotate ±180°, and the fixed cleaning nozzle, the movable cleaning nozzle and the elastic and retractable cleaning tube are started to start all-round cleaning of the outer surface and the inside of the flange; after cleaning is completed, the fixed air-drying nozzle, the movable air-drying nozzle and the elastic and retractable air-drying tube are started to start all-round drying of the outer surface and the inside of the flange.

[0039] The upper liquid level switch senses the signal and starts to drain directly to the corresponding wastewater treatment area through the drainage pipe connected to the bottom of the liquid receiving tank. The lower liquid level switch stops draining when detecting it.

[0040] In addition, there is another embodiment: a pressure sensor is provided on each wall of the box body, and the pressure sensor will not be activated when the high-pressure cleaning liquid sprayed by the mobile cleaning nozzle directly hits the straight pipe and splashes onto the box wall. The pressure sensor will be activated when the high-pressure cleaning liquid sprayed by the mobile cleaning nozzle directly hits the box wall instead of hitting the straight pipe. The activation of the pressure sensor indicates that the mobile cleaning nozzle is invalid; the control unit receives the pressure sensor activation signal, starts the transplanting positioning cylinder to make the mobile bracket return to its original position, starts the electromagnet between the mobile bracket and the upper and lower carrying cylinders, and fixes the upper and lower carrying cylinders to the mobile bracket, and starts the transplanting positioning cylinder again to make the mobile bracket return to the working position. At this time, the transplanting positioning cylinder and the mobile cleaning nozzle also move horizontally close to the straight pipe, thereby making it easier for the high-pressure cleaning water sprayed by the mobile cleaning nozzle to directly hit the straight pipe, thereby ensuring the cleaning effect.

[0041] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
