[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0033] like Figures 1 to 7 As shown, an automatic cleaning device for a corn fermentation tank of the present invention is used to clean a fermentation tank 1;

[0034] The cleaning device comprises a top plate 2 and a sleeve 3 vertically inserted and fixed on the top plate 2, a polygonal disk 4 is rotatably provided at the bottom of the sleeve 3, a connecting arm 5 is rotatably provided on each side wall of the polygonal disk 4, the rotation axis of the connecting arm 5 is horizontal and perpendicular to the axis of the sleeve 3, a brush roller 6 for cleaning the inner wall of the fermentation tank 1 is rotatably provided on the connecting arm 5, and a plurality of nozzles 12 for spraying cleaning liquid are provided on the brush roller 6;

[0035] The rotation axis of the brush roller 6 is parallel to the rotation axis of the connecting arm 5 , an adjusting column 7 is vertically inserted in the middle of the sleeve 3 , the bottom of the adjusting column 7 extends beyond the sleeve 3 , and the adjusting column 7 is connected to each connecting arm 5 via an adjusting arm 8 .

[0036] In detail, the top plate 2 supports the sleeve 3 and the structure thereon, and the top plate 2 can provide the moving power in the vertical direction through the external oil cylinder, so that the top plate 2 and the structure thereon can be inserted into the fermentation tank 1 or removed from the fermentation tank 1 through the top opening of the fermentation tank 1 in the vertical direction, and when the top plate 2 moves in the vertical direction, the multiple brush rollers 6 thereon can clean the inner wall of the fermentation tank 1, the top plate 2 supports the sleeve 3, and the sleeve 3 supports the polygonal disk 4, the connecting arm 5, the brush roller 6, the adjusting column 7 and the adjusting arm 8 thereon, the sleeve 3 only moves in the vertical direction, the polygonal disk 4 can rotate at the bottom of the sleeve 3, the connecting arm 5 supports the brush roller 6, and the connecting arm 5 keeps the downward tilted state, and the connecting arm 5 The adjusting arm 8 on the sleeve 3 remains in an upwardly inclined state, so that when the adjusting column 7 moves up and down in the sleeve 3, it can use the adjusting arm 8 to drive the connecting arm 5 to rotate on the polygonal disk 4, so as to adjust the distance between the brush roller 6 and the axis of the sleeve 3, that is, adjust the coverage of multiple brush rollers 6 on the horizontal plane. When the adjusting column 7 rotates, it can drive the adjusting arm 8, the connecting arm 5 and the brush roller 6 to rotate around the axis of the sleeve 3, so that the position of the brush roller 6 can be adjusted through the adjusting column 7, and the brush roller 6 can be made to move in a circular motion. When the brush roller 6 contacts the inner wall of the fermentation tank 1, the cleaning liquid discharged from the nozzle 12 on the brush roller 6 can rinse the inner wall of the fermentation tank 1, and the brush roller 6 can rotate and brush the inner wall of the fermentation tank 1.

[0037] When in use, the fermentation tank 1 can be moved to the bottom of the sleeve 3 by a mobile vehicle in the workshop, or the top plate 2 can be moved to the top of the fermentation tank 1 by a hanging track in the workshop, so that the top plate 2 and the multiple brush rollers 6 thereon can correspond to the position of the fermentation tank 1, and the top plate 2 can be pushed up and down by the oil cylinder installed on the top plate 2, and the top plate 2 drives the multiple brush rollers 6 downward to insert into the fermentation tank 1 through the top opening of the fermentation tank 1. At this time, the multiple brush rollers 6 are all in a retracted state, that is, the brush rollers 6 are close to the sleeve 3. When the multiple brush rollers 6 are moved into the fermentation tank 1, the adjusting column 7 is pushed and pulled to move upward in the sleeve 3, and the adjusting column 7 pushes the multiple connecting arms 5 to expand around through the multiple adjusting arms 8. The brush rollers 6 are opened, and the multiple brush rollers 6 extend outward and contact the inner wall of the fermentation tank 1. The brush rollers 6 rotate and brush the inner wall of the fermentation tank 1. The nozzles 12 on the brush rollers 6 spray cleaning liquid and rinse the inner wall of the fermentation tank 1. At the same time, the adjusting column 7 is rotated, and the adjusting column 7 drives the multiple brush rollers 6 to perform circular motion around the axis of the sleeve 3, so that the multiple brush rollers 6 are used to clean the inner wall of the fermentation tank 1 on the horizontal plane. With the help of the movement of the top plate 2 in the vertical direction, the multiple brush rollers 6 comprehensively clean the inner wall of the fermentation tank 1, thereby realizing automatic cleaning. The cleaned sewage and impurities can be discharged through the opening or pipe set at the bottom of the fermentation tank 1.

[0038] It should be noted that, since the rotation axis of the brush roller 6 on the connecting arm 5 is horizontal, the brush roller 6 can perform circular motion around the axis of the sleeve 3, and the adjustment column 7 can adjust the distance between the brush roller 6 and the axis of the sleeve 3, so when the brush roller 6 moves to Figure 1 When the brush roller 6 cleans the arc-shaped areas on the upper and lower sides of the fermentation tank 1, the brush roller 6 can still clean the area, thereby achieving comprehensive cleaning of the inner wall of the fermentation tank 1 by the brush roller 6.

[0039] By utilizing the vertical movement and horizontal rotation of multiple brush rollers 6, comprehensive and automatic cleaning of the inner wall of the fermenter 1 can be achieved; by combining automatic brushing and automatic flushing, the cleaning effect of the inner wall of the fermenter 1 can be improved to avoid impurity residue; because the rotation axis of the brush roller 6 is horizontal and the distance between it and the sleeve 3 is adjustable, it is convenient to effectively clean the curved surface area of ​​the inner wall of the fermenter 1 to avoid the generation of cleaning dead corners, and this method can realize the cleaning of fermenters 1 with different diameters; the device has a simple structure and is easy to operate, which greatly simplifies the operation method, and it has higher efficiency, better cleaning effect and higher safety, and can effectively solve the problems in cleaning the fermenter 1.

[0040] Furthermore, the brush roller 6 is composed of two support plates 9 and an airbag 10 located between the two support plates 9. The two support plates 9 are rotatably mounted on the connecting arm 5. The airbag 10 is mounted on the two support plates 9. A plurality of brushes 11 are arranged on the outer wall of the airbag 10, and the nozzle 12 is located between two adjacent brushes 11.

[0041] In detail, the airbag 10 can be made of materials such as polyurethane, polyvinyl chloride, leather, etc., so that the support plate 9 can have a small amount of elastic deformation. The support plate 9 can support the airbag 10, and when the support plate 9 rotates, it can drive the airbag 10 and the brush 11 and nozzle 12 thereon to rotate. The multiple nozzles 12 can be divided into multiple groups, and each group of nozzles 12 is located between two adjacent brushes 11.

[0042] When the cleaning liquid is filled into the airbag 10, the cleaning liquid expands the airbag 10. At this time, the airbag 10 is in an ellipsoidal spherical shape, and the brush 11 on the outer wall of the airbag 10 is in an arc shape. The cleaning liquid in the airbag 10 can be sprayed out through multiple nozzles 12. When the brush roller 6 cleans the inner wall of the fermentation tank 1, the brush 11 on the airbag 10 is squeezed and contacted with the inner wall of the fermentation tank 1. At this time, due to the elastic deformation of the airbag 10, the brush 11 on the airbag 10 can be deformed and contact with a large area of ​​the inner wall of the fermentation tank 1, which can increase the contact area and the cleaning area, and can have a small buffering effect. As the support plate 9 rotates, the airbag 10 will continuously brush the inner wall of the fermentation tank 1 through the multiple brushes 11 thereon.

[0043] Furthermore, a plurality of cylinders 13 are provided on the top plate 2, and the protruding ends of the plurality of cylinders 13 are connected to a connecting plate 14, the top of the adjusting column 7 protrudes to the outside of the sleeve 3, and the connecting plate 14 and the adjusting column 7 are connected via a connecting disk 37 and a spring 15.

[0044] In detail, one end face of the connecting disk 37 is rotatably connected to the adjusting column 7, and the other end face of the connecting disk 37 is fixedly connected to the spring 15. Since the adjusting column 7 needs to rotate on the sleeve 3, the connecting disk 37 is needed to realize the rotational connection relationship between the connecting plate 14 and the adjusting column 7. The fixed end of the cylinder 13 is installed on the top plate 2. When the cylinder 13 is extended or retracted, it can drive the adjusting column 7 to move up and down through the connecting plate 14, the spring 15 and the connecting disk 37, thereby adjusting the position of the brush roller 6.

[0045] It should be pointed out that the setting of the spring 15 can play a buffering role for the adjusting column 7. When the brush roller 6 cleans the arc-shaped position of the inner wall of the fermentation tank 1, due to the reaction force of the inner wall of the fermentation tank 1, the distance between the brush roller 6 and the sleeve 3 will change. At this time, the spring 15 will undergo elastic deformation, so that the position of the brush roller 6 can move along the trajectory of the inner wall of the fermentation tank 1 when the state of the cylinder 13 remains unchanged.

[0046] Furthermore, a motor 16 is provided on the top plate 2, a transmission wheel 17 is provided at the output end of the motor 16, a transmission ring 18 is provided on the transmission wheel 17, the transmission ring 18 is sleeved on the outer side of the adjustment column 7, and the transmission ring 18 is rotatably mounted on the top of the sleeve 3;

[0047] Therein, a plurality of slide grooves are provided on the outer wall of the adjusting column 7, and a plurality of ridges are provided on the inner wall of the transmission ring 18, and the ridges are slidably installed in the slide grooves.

[0048] In detail, when the adjusting column 7 moves in the vertical direction, it can slide relative to the transmission ring 18. When the motor 16 is running, it can drive the adjusting column 7 to rotate through the transmission wheel 17 and the transmission ring 18, thereby providing power for the circular motion of multiple brush rollers 6. The slide groove on the adjusting column 7 and the edge on the transmission ring 18 can play a guiding role for the adjusting column 7.

[0049] Furthermore, a fixed disk 19 is fixedly mounted on the outer wall of the sleeve 3, and a plurality of rollers 20 are provided on the outer circumferential wall of the fixed disk 19. A prism shaft 21 is vertically slidably inserted through the middle of the roller 20, and a universal joint 22 is connected to the bottom of the prism shaft 21, and a worm 23 is connected to the universal joint 22;

[0050] The connecting arm 5 is rotatably provided with a short shaft 24 which is transmission-connected to a supporting plate 9 , and the short shaft 24 is provided with a worm gear 25 which is meshingly connected to the worm 23 . When the brush roller 6 moves in a circle around the axis of the sleeve 3 , the roller 20 moves synchronously and rolls on the fixed plate 19 .

[0051] In detail, when the polygonal disk 4 and multiple brush rollers 6 thereon perform circular motion around the axis of the sleeve 3, the roller 20 will move synchronously with the brush roller 6. At this time, the roller 20 rolls on the fixed disk 19, and the roller 20 drives the worm wheel 25 to rotate through its upper prism shaft 21, universal joint 22 and worm 23. The worm wheel 25 drives a support disk 9 to rotate through the short shaft 24, thereby driving the airbag 10 and another support disk 9 to rotate, thereby providing power for the self-rotation motion of the brush roller 6.

[0052] When the adjusting column 7 moves and changes the distance between the brush roller 6 and the sleeve 3, the worm 23 and the worm wheel 25 remain in meshing state, the prism shaft 21 slides vertically on the roller 20, and the roller 20 and the prism shaft 21 remain in a transmission state.

[0053] Furthermore, a support ring 26 is sleeved on the outer side of the short shaft 24 , and the support ring 26 is rotatably mounted on the support disk 9 . A support plate 27 is arranged on the support ring 26 , and the worm 23 passes through the support plate 27 and is rotatably connected to each other.

[0054] In detail, the support ring 26 and the support plate 27 can support the worm 23 so that the worm 23 and the worm wheel 25 always maintain a meshing state. When the distance between the brush roller 6 and the sleeve 3 changes, the support ring 26 will rotate on the connecting arm 5.

[0055] Furthermore, a rotating ring 28 is rotatably provided on the fixed plate 19 , and a plurality of sleeve rings 29 are provided on the rotating ring 28 , and the rollers 20 pass through the sleeve rings 29 and are rotatably connected to each other.

When the brush roller 6 performs a circular motion, it can pull the roller 20 to roll on the fixed disk 19 through the worm 23, and the rotating ring 28 rotates on the fixed disk 19. When the distance between the brush roller 6 and the sleeve 3 changes, due to the connection between the support ring 26 and the support plate 27, the worm 23 can drive the prism shaft 21 to slide on the roller 20 through the universal joint 22.

[0057] Furthermore, a first material guide groove 30 is fixedly sleeved on the outer wall of the sleeve 3, a second material guide groove 31 is rotatably sleeved on the outer side of the first material guide groove 30, a closed chamber is formed between the first material guide groove 30 and the second material guide groove 31, a feed pipe 32 is connected to the first material guide groove 30, a hose 33 is connected to the second material guide groove 31, and the swivel 28 and the second material guide groove 31 are connected by a plurality of vertical rods 34;

[0058] The short shaft 24 is provided with a right-angle material pipe 35, which is connected to the inside of the airbag 10, and the right-angle material pipe 35 is fixedly connected to the support plate 27 through a fixing plate 36, and the right-angle material pipe 35 is connected to the hose 33;

[0059] The right-angle material tube 35 and the short shaft 24 rotate relative to each other.
