[0026] In this embodiment, Figure 1 As shown, the kettle body 1 is used as the main container for reaction and cleaning, and its design should be able to withstand various pressure and temperature changes during the cleaning process. The kettle cover 15 closes the top of the kettle body 1 to ensure safety and sealing during the cleaning process. The motor 10 is installed on the top of the kettle cover 15 to provide driving force to rotate the shaft 6, thereby driving the cleaning airbag 2 to clean in the kettle body 1. The hollow design of the shaft 6 allows the cleaning liquid or gas to flow to the airbag, and is connected to the coupling 8 to ensure that the power output by the motor 10 can be smoothly transmitted. The cleaning airbag 2 is fixed on the outside of the shaft 6, and its side wall is composed of an inner wall 202 and an outer wall 201 to form an annular air cavity. 3. When the airbag is filled with gas, it will expand and cling to the inner wall 202 of the kettle body 1, and clean the kettle body 1 through rotation and friction. The supporting airbag 45 is located inside the cleaning airbag 2 and communicates with the cleaning airbag 2. When the supporting airbag 45 is inflated, it provides support for the cleaning airbag 2 to ensure that the cleaning airbag 2 can maintain its shape and stability when inflated. The air inlet 13 is provided on the side wall of the rotating shaft 6 for filling the supporting airbag 45 with gas. The sealing plug 11 is located at the air inlet 13 to play a sealing role. When inflation is required, the sealing plug 11 can be opened; after inflation is completed, the sealing plug 11 is closed to ensure that the gas in the airbag does not leak.

[0027] First, gas is filled into the supporting airbag 45 through the air inlet hole 13, and the supporting airbag 45 expands and supports the cleaning airbag 2. After the cleaning airbag 2 expands, it is close to the inner wall 202 of the kettle body 1, and then the sealing plug 11 is installed. After the motor 10 is started, the output shaft 9 drives the rotating shaft 6 to rotate in the kettle body 1. As the rotating shaft 6 rotates, friction is generated between the cleaning airbag 2 and the inner wall 202 of the kettle body 1, thereby removing the residue in the kettle body 1. After cleaning is completed, the sealing plug 11 can be removed to discharge the gas in the airbag, so that the airbag is restored to its original state for the next use. The design of this cleaning mechanism not only improves the cleaning efficiency, but also reduces the damage to the inner wall 202 of the kettle body 1 through the flexible contact of the airbag, thereby extending the service life of the kettle body 1. At the same time, it can also adapt to kettle bodies 1 of different shapes and sizes, has good versatility, can more conveniently clean the inner wall 202 of the reactor, the cleaning process is simple and fast, and the cleaning effect is good.

[0028] Optionally, the supporting airbag 45 includes a connecting sleeve 5 and a supporting sleeve 4 made of rubber material. The connecting sleeve 5 is sleeved on the rotating shaft 6 and bonded to the side wall of the rotating shaft 6. One end of the supporting sleeve 4 is connected to the inner wall 202 of the cleaning airbag 2, and the other end is connected to the outer wall 201 of the connecting sleeve 5. The supporting sleeve 4 connects the annular air cavity 3 and the hollow cavity 12 of the rotating shaft 6. The upper and lower ends of the connecting sleeve 5 are respectively connected to the cleaning airbag 2.

[0029] Specifically, the choice of rubber material makes the connecting sleeve 5 both elastic enough to adapt to various deformations during the cleaning process and has good sealing properties to ensure that gas will not leak from the connection. The connecting sleeve 5 is sleeved on the rotating shaft 6 and bonded to the side wall of the rotating shaft 6. This design not only ensures the firmness of the connection, but also allows the gas to flow smoothly from the hollow cavity 12 of the rotating shaft 6 into the supporting airbag 45. One end of the supporting sleeve 4 is connected to the inner wall 202 of the cleaning airbag 2, and the other end is connected to the outer wall 201 of the connecting sleeve 5. This connection method forms a continuous air path, allowing the gas to flow smoothly from the rotating shaft 6 into the supporting airbag 45, and then further into the annular air cavity 3 of the cleaning airbag 2. The main function of the supporting sleeve 4 is to provide support to ensure that the cleaning airbag 2 can maintain a stable shape and sufficient expansion when inflated. At the same time, since the supporting sleeve 4 is directly connected to the inner wall 202 of the cleaning airbag 2, it can more effectively transmit the cleaning force and improve the cleaning effect. The design of the support sleeve 4 allows the annular air cavity 3 to communicate with the hollow cavity 12 of the rotating shaft 6. In this way, when the gas enters the hollow cavity 12 of the rotating shaft 6 through the air inlet 13, it can quickly fill the support airbag 45 and further flow into the annular air cavity 3 of the cleaning airbag 2 to achieve rapid expansion of the airbag. The upper and lower ends of the connecting sleeve 5 are connected to the cleaning airbag 2. This design enhances the integrity of the support airbag 45 and the cleaning airbag 2, allowing the two to work together during the cleaning process to improve the cleaning effect. At the same time, this connection method also helps to maintain the sealing of the airbag and prevent gas leakage. The design of this support airbag 45 not only takes into account the stability and sealing of the structure, but also fully considers the cleaning effect and convenience of operation. Through the selection of rubber materials, the ingenious connection of various components and the reasonable design of the gas path, the entire cleaning mechanism can efficiently and safely complete the cleaning task of the reactor.

[0030] Optionally, a rubber fixing plate 7 is provided in the middle of the top and bottom surfaces of the cleaning airbag 2, the fixing plate 7 partitions the annular air cavity 3, the two ends of the connecting sleeve 5 are respectively connected to the corresponding fixing plates 7, the lower end of the rotating shaft 6 passes through the upper fixing plate 7, the connecting sleeve 5, and the lower fixing plate 7 in sequence, and the rotating shaft 6 is fixedly connected to the fixing plate 7.

[0031] Specifically, the fixing plate 7 is made of rubber material, which has good elasticity and durability, and can ensure that the fixing plate 7 always maintains a stable shape and performance during the cleaning process. The fixing plates 7 are respectively arranged at the middle of the top surface and the bottom surface of the cleaning airbag 2. This layout enables the fixing plate 7 to evenly distribute the supporting force of the cleaning airbag 2 to prevent the airbag from over-expanding or deforming when inflating. The fixing plate 7 not only plays a supporting and fixing role, but also can separate the annular air cavity 3 and divide the internal space of the airbag into different areas. This design helps to better control the expansion degree and shape of the airbag and improve the cleaning effect. The two ends of the connecting sleeve 5 The ends are respectively connected to the corresponding fixed plates 7. This connection method ensures a firm connection between the support airbag 45 and the cleaning airbag 2. At the same time, due to the presence of the fixed plate 7, the connecting sleeve 5 can maintain a stable position when inflated and will not be displaced due to the expansion of the airbag. The lower end of the rotating shaft 6 passes through the upper fixed plate 7, the connecting sleeve 5, and the lower fixed plate 7 in sequence, and is fixedly connected to the fixed plate 7. This design forms a stable structural whole between the rotating shaft 6 and the cleaning airbag 2, ensuring that the airbag can always remain in the correct position during the rotation and cleaning process, and will not be offset or shaken due to the action of centrifugal force. The design of this cleaning airbag 2 and its related components fully considers structural stability, cleaning effect and convenience of operation. Through the setting of the fixed plate 7 and the ingenious connection with the connecting sleeve 5 and the rotating shaft 6, the entire cleaning mechanism can maintain stable performance and efficient cleaning effect when working.

[0032] Optionally, an air outlet hole 14 corresponding to the supporting sleeve 4 is provided on the side wall of the rotating shaft 6 , and the air outlet hole 14 is connected to the annular air cavity 3 and the hollow cavity 12 of the rotating shaft 6 .

[0033] Specifically, Figure 3 As shown, the air outlet 14 is arranged on the side wall of the rotating shaft 6, corresponding to the supporting sleeve 4. This position setting enables the gas to directly and efficiently enter the supporting sleeve 4 when flowing, reduces the resistance of gas flow, and improves the inflation efficiency. The air outlet 14 is not only connected to the supporting sleeve 4, but also connected to the annular air cavity 3 and the hollow cavity 12 of the rotating shaft 6. This design forms a complete air path, allowing the gas to flow freely between the three. When the gas enters the hollow cavity 12 of the rotating shaft 6 from the air inlet 13, it can quickly flow into the supporting sleeve 4 through the air outlet 14, and then fill the entire supporting airbag 45 and the annular air cavity 3 of the cleaning airbag 2. The setting of the air outlet 14 makes the inflation process of the cleaning airbag 2 faster and more uniform, and the gas can quickly fill the entire airbag, so that it reaches an ideal expansion state in a short time.

[0034] Optionally, the supporting sleeves 4 are provided in plurality and are distributed in an annular shape around the connecting sleeve 5 , and the plurality of supporting sleeves 4 form a circular supporting surface on a horizontal plane.

[0035] Optionally, a plurality of circular supporting surfaces are provided at intervals along the length direction of the connecting sleeve 5 .

[0036] Specifically, Figure 1 and Figure 2 As shown, a plurality of supporting sleeves 4 are arranged in the circumferential direction of the connecting sleeve 5, and these supporting sleeves 4 are evenly distributed to form an annular array. This design not only provides a stronger supporting force, making the cleaning airbag 2 more stable when inflated and less prone to deformation or displacement, but also increases the cleaning coverage area of ​​the airbag, making the cleaning more comprehensive and efficient. The plurality of supporting sleeves 4 together form a circular supporting surface on the horizontal plane, and this supporting surface is tightly fitted with the inner wall 202 of the cleaning airbag 2, providing a uniform supporting force for the airbag. This design helps to maintain the stability of the shape of the airbag and prevent the occurrence of In the case of local over-expansion or contraction, in an optional design, multiple circular support surfaces are arranged at intervals along the length direction of the connecting sleeve 5. This design further increases the number of support points and improves the overall stability and durability of the cleaning airbag 2. At the same time, the circular support surfaces arranged at intervals also help to better adapt to kettles 1 of different shapes and sizes, and improve the versatility of the cleaning mechanism. The design of this support sleeve 4 fully considers the stability and cleaning effect of the cleaning mechanism. Through the annular distribution of multiple support sleeves 4 and the formation of circular support surfaces, strong support and stable cleaning performance are provided for the cleaning airbag 2. This design not only improves the cleaning efficiency, but also extends the service life of the cleaning mechanism, bringing significant improvements to the cleaning work of the reactor.

[0037] Optionally, a brush is provided on the outer wall 201 of the cleaning airbag 2 .

[0038] Specifically, the brush (not shown) is closely attached to the outer wall 201 of the cleaning airbag 2. When the airbag is inflated and rotated with the rotating shaft 6, the brush will be in close contact with the inner wall 202 of the kettle body 1 and produce friction. This friction can effectively remove stubborn stains, residues, etc. attached to the inner wall 202 of the kettle body 1, thereby achieving deep cleaning. The brush has certain flexibility and adaptability, and can fit the inner wall 202 of the kettle body 1 of different shapes and surfaces. Whether it is a flat surface, a curved surface or an uneven surface, the brush can effectively clean without leaving dead corners. Compared with traditional cleaning tools, the brush has a longer service life, it is not easy to wear, and can withstand the test of multiple cleanings. At the same time, the replacement of the brush is relatively simple and convenient, which reduces the maintenance cost. Due to the combination of the brush and the airbag, the cleaning mechanism can simultaneously utilize the friction of the airbag and the cleaning power of the brush when rotating, thereby improving the cleaning efficiency, which makes the entire cleaning process faster and more efficient. In summary, the brushes provided on the outer wall 201 of the cleaning airbag 2 not only enhance the cleaning effect, but also improve the cleaning efficiency and service life. This innovative design makes the cleaning mechanism more suitable for cleaning various reactors, bringing convenience and benefits to industrial production.

[0039] Optionally, the sealing plug 11 is a threaded plug made of rubber material, and an internal thread matching the sealing plug 11 is provided on the hole wall of the air inlet hole 13 .

[0040] Specifically, the rubber material has good elasticity and sealing properties, so that the threaded plug can fit tightly on the wall of the air inlet hole 13 to ensure that gas will not leak from the gap. The rubber also has certain wear resistance and corrosion resistance, and can maintain its good performance for a long time, thereby extending its service life. The threaded plug and the internal threads on the wall of the air inlet hole 13 are compatible with each other. This design makes the installation and disassembly of the sealing plug 11 simple and convenient. By rotating the threaded plug, it can be easily tightened or loosened to open and close the air inlet hole 13. The tight fit of the threads also enhances the sealing effect and further prevents gas leakage. Using the threaded plug as the sealing plug 11 allows operators to quickly and accurately complete operations when inflating or deflating, thereby improving work efficiency.
