[0004] However, in the prior art, the sleeve and the spray ball connecting pipe are installed by means of a clamp, and the clamp needs to be installed in conjunction with bolts and nuts when in use. When disassembling the spray ball connecting pipe, the staff needs to move it to the tank top through a lifting device, and then use a disassembly tool to disassemble the clamp, which is inconvenient for quick disassembly; and the cleaning ball mentioned in the prior art is fixedly arranged, that is, the cleaning liquid can only flush and clean the inside of the tank body through the leakage hole on the cleaning ball, and the cleaning effect is not good; for this reason, we designed an integrated tank top assembly.

There is no need to detach the connecting bolt, and there is no need to worry about the loss of the bolt and the nut. Then the connecting bolt is rotated to make the connecting bolt disengage from the groove on the second jacket mounting block. At this time, the first jacket and the second jacket are opened, and the connecting elbow and the sleeve can be quickly disassembled and assembled. At the same time, sealing gaskets are provided on the inner walls of the first jacket and the second jacket to ensure that the installation connection between the connecting elbow and the sleeve is well sealed and convenient for maintenance.

At the same time, the output end of the driving motor drives the second bevel gear to engage with the first bevel gear for transmission. Since the first bevel gear is coaxially arranged on the bearing, it drives the cleaning ball to rotate. At this time, the cleaning liquid rotates and flushes the inner wall of the fermentation tank through the leakage hole on the rotating cleaning ball, thereby realizing all-round spray flushing of the inner wall of the fermentation tank, and the cleaning effect is better.

[0019] Optionally, a filter is provided at the air inlet of the vacuum valve, and a pressure display gauge is provided on the regulating safety valve.

[0020] By adopting the above technical solution, dust particles can be prevented from being carried in the ambient air of the factory.

A sealing box 10 is provided on the spray ball connecting pipe 4. A mounting mechanism is provided in the sealing box 10. The mounting mechanism is used to drive the cleaning ball 5 to rotate and rinse the fermentation tank body;

[0031] The mounting mechanism comprises a driving motor 8, a first bevel gear 7 and a second bevel gear 9. The bearing 6 is arranged on the inner wall of the sealing box 10, and the bearing 6 is rotatably connected to the sealing box 10.

The first bevel gear 7 is coaxially fixedly connected to the bearing 6. The driving motor 8 is fixedly mounted on the inner wall of the sealing box 10. The output end of the driving motor 8 is coaxially fixedly connected to the second bevel gear 9. The second bevel gear 9 is meshed with the first bevel gear 7 for transmission. The output end of the driving motor 8 drives the second bevel gear 9 to mesh with the first bevel gear 7 for transmission. Since the first bevel gear 7 is coaxially arranged on the bearing 6, the cleaning ball 5 is driven to rotate.

[0032] Reference Figure 1 and Figure 4 The vacuum valve 13 is connected to the sleeve 1 through the first connecting pipe 12, and a third connecting pipe is provided between the vacuum valve 13 and the regulating safety valve 14. The regulating safety valve 14 is connected to the exhaust pipe 16, and the connecting elbow 3 is connected to the flushing pipe 24. The flushing pipe 24 runs through the sleeve 1. The vacuum valve 13 is provided with a second connecting pipe 23, and the flushing pipe 24 is coaxially arranged in the first connecting pipe 12 and the second connecting pipe 23. The end of the flushing pipe 24 away from the connecting elbow 3 is connected to the exhaust pipe 16. The sleeve 1, the vacuum valve 13, and the regulating safety valve 14 are flushed by the corresponding nozzles arranged on the flushing pipe 24. The waste liquid is finally discharged from the component through the exhaust pipe 16, or flows into the fermentation tank body through the sleeve 1.

[0033] Reference Figure 1 and Figure 5 The spray ball connecting pipe 4 is coaxially inserted in the sleeve 1, and a quick disassembly mechanism is provided between the sleeve 1 and the connecting elbow 3, and the quick disassembly mechanism is used to facilitate quick disassembly of the spray ball connecting pipe 4;

[0034] The quick disassembly mechanism includes a first jacket 17 and a second jacket 18, both of which are semicircular, and one end of the first jacket 17 and the second jacket 18 is rotatably connected by a rotating shaft, and the other end is fixedly connected with a mounting block 21, and the mounting block 21 is provided with a clamping groove at one end away from the first jacket 17 and the second jacket 18, and the first jacket 17 and the second jacket 18 are used to fix and clamp the installation connection between the connecting elbow 3 and the sleeve 1;

The inner wall of the screw hole of the eye nut 20 is provided with a screw thread that matches the thread of the connecting bolt 19. The eye nut 20 is arranged at an end of the connecting bolt 19 away from the first jacket 17. By rotating the eye nut 20, the eye nut 20 is moved away from the first jacket 17 by a certain distance. Then the connecting bolt 19 is rotated to disengage the connecting bolt 19 from the groove on the mounting block 21 of the second jacket 18. At this time, the first jacket 17 and the second jacket 18 are opened, and the operation is simple and convenient.

[0036] Reference Figure 5 The diameter of the connecting bolt 19 is smaller than the width of the clamping groove, the lifting eye nut 20 includes a nut and a lifting eye, and the size of the lifting eye nut 20 is larger than the width of the clamping groove. The effect of this arrangement is that the mounting block 21 on the first jacket 17 and the second jacket 18 is clamped by the cooperation of the lifting eye nut 20 and the connecting bolt 19, which facilitates the fixed installation of the first jacket 17 and the second jacket 18 at the installation connection of the connecting elbow 3 and the sleeve 1, while avoiding the loss of the disassembled bolts and nuts.

The effect of this arrangement is to prevent external dust from entering the valve body of the vacuum valve 13 and the tank body of the fermenter. A pressure display gauge 15 is provided on the regulating safety valve 14 for real-time display of the pressure inside the fermenter tank and timely adjustment of the air pressure.

[0038] The working principle of the utility model is as follows:

[0039] When it is necessary to rinse and clean the fermentation tank, the cleaning liquid is transported to the liquid inlet pipe 22 through the external liquid pump, and then enters the cleaning ball 5 through the spray ball connecting pipe 4. At the same time, the output end of the driving motor 8 drives the second bevel gear 9 to mesh with the first bevel gear 7. Since the first bevel gear 7 is coaxially arranged on the bearing 6, the cleaning ball 5 is driven to rotate. At this time, the cleaning liquid rotates through the leakage hole on the rotating cleaning ball 5 to rotate and rinse the inner wall of the fermentation tank, so as to realize all-round spraying and flushing of the inner wall of the fermentation tank, and the cleaning effect is good.

[0040] At the same time, since the flushing pipe 24 is connected to the liquid inlet pipe 22, the sleeve 1, the vacuum valve 13, and the regulating safety valve 14 are flushed through the nozzles correspondingly arranged on the flushing pipe 24, and the waste liquid is finally discharged from the assembly through the exhaust pipe 16, or flows into the fermentation tank body through the sleeve 1;

[0041] When the spray ball connecting pipe 4 needs to be maintained, the eye nut 20 is rotated to make the eye nut 20 away from the first jacket 17 by a certain distance (there is no need to disengage the connecting bolt 19, and there is no need to worry about the loss of the bolt and nut), and then the connecting bolt 19 is rotated to make the connecting bolt 19 disengage from the groove on the mounting block 21 of the second jacket 18. At this time, the first jacket 17 and the second jacket 18 are opened, so that the connecting elbow 3 and the sleeve 1 can be quickly disassembled and assembled.
