Description

Technical Field

[0001] The invention relates to the technical field of ethyl acetate production equipment, in particular to an esterification kettle for ethyl acetate production. Background Art

[0002] Esterification reactors are specialized equipment widely used in chemical engineering, food processing, pharmaceutical manufacturing, and other fields. They react acids with alcohols or acids with anhydrides to produce ester compounds by controlling parameters such as temperature, pressure, and agitation. Esterification reactors are widely used in the chemical industry, often in the production of food additives, oils and fats, flavors and fragrances, polyester resins, pharmaceutical raw materials, and dyes. They are also used in scientific research fields such as catalyst preparation and catalytic reaction research.

[0003] In traditional esterification reaction equipment, the accuracy and sealing of raw material feeding are one of the key factors affecting production efficiency and product quality. The existing equipment cleaning method is to use a scraper to scrape off these residues. When the scraper is scraping off the residues, due to the cutting angle formed by the blade and the reaction barrel, some residues often remain on the barrel wall when in contact, making it difficult to completely scrape off the adhesions on the inner wall of the reaction barrel. These residual adhesions may easily interfere with the mixing of raw materials and the transfer of excess heat in the next round of production. Therefore, the present application provides an esterification kettle for ethyl acetate production to meet the needs. Summary of the Invention

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up a blanking component and utilizing the sliding cooperation between the electric slide rail and the sliding base, the positioning effect of the feed pipe is achieved. At the same time, through the sealing cooperation between the feed box and the sealing gasket, the chemical stability and corrosion resistance of polytetrafluoroethylene are utilized to improve the service life of the sealing gasket, and avoid the sealing gasket and the sealing gasket ring being corroded by the ethyl acetate production raw materials during ethyl acetate production, resulting in a decrease in the sealing effect, thereby causing the corrosive liquid contained in the ethyl acetate production raw materials to leak, thereby improving the safety during ethyl acetate production, and at the same time avoiding the leakage and waste of ethyl acetate production raw materials caused by the decrease in the sealing effect of the sealing gasket and the sealing gasket ring, thereby reducing the material cost during ethyl acetate production.

[0016] By setting a rotating component and a special stirring plate on the inner wall of the stirring barrel, the ethyl acetate production raw material liquid in the stirring barrel is mixed and stirred. At the same time, the linkage effect of the circular slide rail and the sliding bracket is coordinated to realize that when the collaborative component cleans the inner wall of the reaction barrel, the port at one end of the discharge pipe located inside the stirring barrel is always located above the liquid level in the stirring barrel, avoiding the surface of the bottom end of the discharge pipe being contaminated with the ethyl acetate production raw material liquid, thereby avoiding the waste of ethyl acetate production raw material. At the same time, by arranging the port position of one end of the discharge pipe located inside the stirring barrel on the inner side of multiple groups of stirring plates, when the stirring barrel drives the multiple groups of stirring plates to mix and stir the ethyl acetate production raw material liquid, the stirring The plate performs turbulent mixing on the falling ethyl acetate production raw material liquid, further improving the mixing and stirring effect of the ethyl acetate production raw material liquid, and further ensuring the reaction effect of the ethyl acetate production raw material liquid after mixing, thereby improving the production efficiency of ethyl acetate. At the same time, by setting the solenoid valve, the liquid exchange effect between the stirring barrel and the reaction barrel is realized. Through the liquid level balance effect between the stirring barrel and the reaction barrel, the liquid surface area of the ethyl acetate production raw material liquid after stirring and mixing is increased, thereby improving the heating effect of the heating equipment on the ethyl acetate production raw material liquid, accelerating the evaporation rate of the ethyl acetate production raw material liquid, and thus improving the production rate of ethyl acetate.

[0017] By setting up a switching component, specially designing the cross-sectional shape of the upper clamping column and the lower clamping column, and coordinating the elastic cooperation between the wedge block and the spring, the limiting and releasing effects of the wedge block are achieved, thereby realizing the switching of the connection mode between the feed box and the discharge pipe, and realizing the rapid mechanical locking of the feed box and the discharge pipe. The elastic reset mechanism of the spring can ensure the contact stability between the wedge block and the upper clamping column and the lower clamping column, thereby avoiding accidental disengagement of the wedge block due to equipment vibration, which may cause the feed box and the discharge pipe to fall and leak raw materials.

[0018] By setting up a cooperative component, the rotation effect of the cleaning roller and the sponge cleaning block is utilized to achieve the cleaning effect of the inner wall of the reaction barrel. The corrosion resistance and high temperature resistance of the polyester sponge are utilized to ensure the cleaning effect of the sponge cleaning block on the inner wall of the reaction barrel while improving the service life of the sponge cleaning block. The flexible contact wiping between the cleaning block and the reaction barrel has a cleaning efficiency that is higher than that of the traditional scraper. It can reduce the residual adhesion on the inner wall of the reaction barrel, avoid the inability to scrape thoroughly when using the scraper, and avoid the scraper contacting the inner wall of the reaction barrel to damage the reaction barrel. At the same time, the spraying and suction effects of the cleaning nozzle and the suction pipe are coordinated to achieve the synchronous operation of the cleaning and recovery functions of the cooperative component. At the same time, the cleaning nozzle and the collection pipe are separately arranged at the top and bottom positions of the cleaning roller The collecting plate realizes the utilization and recovery of the sprayed cleaning agent, and realizes the virtuous cycle of the "use-recovery" function of the cleaning agent. At the same time, when the ethyl acetate production raw material liquid achieves liquid level equilibrium between the stirring barrel and the reaction barrel, it prevents the residue on the inner wall of the reaction barrel from entering the ethyl acetate production raw material liquid for a second time, thereby interfering with the heating reaction of the ethyl acetate production raw material liquid, ensuring the purity of the ethyl acetate production raw material liquid, and further ensuring the yield rate during ethyl acetate production. At the same time, after the sponge cleaning block cleans the reaction barrel, the heat generated by the heating equipment during heating is reused, the cleaned inner wall of the reaction barrel is dried, and the reaction barrel is pre-heated, further improving the evaporation rate of the ethyl acetate production raw material liquid.

[0028] like Figures 1 to 14As shown, an embodiment of the present invention provides an esterification kettle for ethyl acetate production, comprising an equipment housing 1, a control module 2 is installed at one end of the surface of the equipment housing 1, a mechanical arm 3 is installed on one side of the top end of the inner wall of the equipment housing 1, a reaction barrel 4 is installed on the inner wall of the equipment housing 1, one end of the mechanical arm 3 is connected to a protective cover 5, the outer surface of the protective cover 5 is in contact with the inner wall of the reaction barrel 4, an air outlet 50 is installed through one side of the top end of the protective cover 5, a first motor 6 is installed on the top of the protective cover 5, a rotating base 7 is nested and installed at the center of the protective cover 5, the top of the rotating base 7 is connected to the bottom end of the first motor 6, an electric push rod 8 is installed on the bottom end of the rotating base 7, the bottom end of the electric push rod 8 is connected to a mounting base 9, and a first motor 6 is installed in the inner wall chamber of the reaction barrel 4. It is equipped with a heating device 10, and a blanking component 11 is installed at the bottom of the mounting base 9. The blanking component 11 is used to transport and discharge the raw materials for ethyl acetate production. A rotating component 12 is nested and installed at the bottom of the inner wall of the reaction barrel 4. The rotating component 12 is used to mix and stir the raw materials for ethyl acetate production. A switching component 13 is installed at the bottom of the blanking component 11. The switching component 13 is used to realize the switching of the connection mode between the blanking component 11 and the rotating component 12. A cooperative component 14 is installed on one side of the blanking component 11. The cooperative component 14 is used to clean the inner wall of the reaction barrel 4. The rotating component 12 is located at the bottom of the blanking component 11, the switching component 13 is located at the bottom edge of the blanking component 11, and the cooperative component 14 is located on one side of the blanking component 11.

[0029] By setting up the unloading component 11 and utilizing the chemical stability and corrosion resistance of polytetrafluoroethylene, the service life of the sealing gasket 116 is improved, and the sealing gasket 116 and the sealing gasket ring 127 are prevented from being corroded by the ethyl acetate production raw materials during ethyl acetate production, resulting in a decrease in the sealing effect, thereby causing the corrosive liquid contained in the ethyl acetate production raw materials to leak, thereby improving the safety during ethyl acetate production. By setting up the rotating component 12, the mixing and stirring effect of the ethyl acetate production raw material liquid is further improved, and at the same time, the reaction effect of the ethyl acetate production raw material liquid after mixing is further guaranteed, thereby improving the production efficiency of ethyl acetate. By setting up the switching component 13, the wedge block 134 is prevented from accidentally disengaging due to equipment vibration, resulting in leakage of raw materials caused by the falling of the feed box 115 and the discharge pipe 126. By setting up the cooperative component 14, the utilization and recovery of the sprayed cleaning agent is realized, and a virtuous cycle of the "use-recycling" function of the cleaning agent is realized.

[0030] like Figures 5 and 6As shown, the unloading component 11 includes an electric slide rail 111, which is installed at the bottom end of the mounting base 9. A sliding base 112 is provided on the surface of the electric slide rail 111. Mounting brackets 113 are connected on both sides of the sliding base 112. A feed pipe 114 is installed on one side of the mounting bracket 113. Part of the surface of the feed pipe 114 is nested and installed on the inner wall of the rotating base 7. The bottom end of the feed pipe 114 is connected with a feed box 115. The feed box 115 is installed on one side of the bottom end of the mounting bracket 113. A sealing gasket 116 is installed on the surface of the extended part of the bottom end of the feed box 115. The material of the sealing gasket 116 is set to polytetrafluoroethylene.

[0031] The operator first starts the robotic arm 3 through the control module 2. After the robotic arm 3 is started, it drives the protective cover 5 to approach the reaction barrel 4, so that the outer surface of the protective cover 5 contacts the inner wall of the reaction barrel 4 and is sealed. Subsequently, the control module 2 controls the electric slide rail 111 to start. Under the action of the electric slide rail 111, the sliding base 112 sleeved on the surface of the electric slide rail 111 slides along the direction of the electric slide rail 111. When the sliding base 112 slides, it drives the mounting bracket 113 to slide synchronously. When the mounting bracket 113 slides, it drives the feeding box 115 to slide synchronously, so that the bottom center of the feeding box 115 and the center of the discharge pipe 126 are located in the same axial direction. At this time, the port of one end of the discharge pipe 126 located inside the mixing barrel 120 is located at the bottom of the inner wall of the mixing barrel 120, and the circular slide rail 124 is located at the bottom of the outer surface of the mixing barrel 120. Subsequently, the control module 2 controls the electric push rod 8 to start. After the electric push rod 8 is started, it pushes the installation base plate 9 to slide downward. While the installation base plate 9 slides, the installation bracket 113 is driven to slide downward synchronously through the electric slide rail 111 and the sliding base 112. While the installation bracket 113 slides, it drives the feed box 115 at the bottom to slide downward synchronously. While the feed box 115 slides, it gradually approaches the inner wall of one end of the discharge pipe 126, and makes the sealing gasket 116 on the surface of the extended part of the bottom end of the feed box 115 contact with the sealing gasket ring 127, so that the surface of the sealing gasket 116 is in close contact with the inner wall of the sealing gasket ring 127.

[0032] By setting up a sliding fit between the electric slide rail 111 and the sliding base 112, the positioning effect of the feed tube 114 is achieved. At the same time, through the sealing fit between the feed box 115 and the sealing gasket 116, the service life of the sealing gasket 116 is improved by utilizing the chemical stability and corrosion resistance of polytetrafluoroethylene.

[0033] like Figures 7 to 9As shown, the rotating assembly 12 includes a stirring barrel 120, which is nested and installed at the bottom end of the inner wall of the reaction barrel 4. A solenoid valve 121 is installed on one side of the bottom end of the stirring barrel 120. The part of the bottom end of the stirring barrel 120 extending from the reaction barrel 4 is connected to a second motor 122, and the second motor 122 is installed at the bottom end of the reaction barrel 4. A stirring plate 123 is installed on the inner wall of the stirring barrel 120. The number of stirring plates 123 is set to multiple groups, and the multiple groups of stirring plates 123 are installed at equal angles in a circular array on the inner wall of the stirring barrel 120. A circular slide rail 124 is provided on the outer surface of the stirring barrel 120, and a sliding bracket 125 is provided on the outer surface of the circular slide rail 124. A discharge pipe 126 is installed on one side of the sliding bracket 125. A sealing gasket 127 is installed on the inner wall of one end of the discharge pipe 126. The inner wall of the sealing gasket 127 contacts the surface of the sealing gasket 116, and the material of the sealing gasket 127 is set to polytetrafluoroethylene. Subsequently, the control module 2 controls the first motor 6 to start, and after the first motor 6 starts, it drives the rotating base 7 to rotate synchronously. When the rotating base 7 rotates, it drives the electric push rod 8, the mounting base 9, the electric slide rail 111, the sliding base 112 and the mounting bracket 113 to rotate synchronously. At the same time, the operator sequentially pumps the ethyl acetate production raw material into the feed pipe 114 through the water pump equipment, so that the ethyl acetate production raw material enters the discharge pipe 126 through the feed pipe 114, and continuously enters the mixing barrel 120 through the discharge pipe 126; When the ethyl acetate production raw materials enter the mixing barrel 120, the control module 2 controls the second motor 122 to start, and under the action of the second motor 122, the mixing barrel 120 is rotated. When the mixing barrel 120 rotates, the multiple groups of stirring plates 123 on the inner wall are driven to rotate synchronously, so as to fully stir the mixed liquid of the ethyl acetate production raw materials in the mixing barrel 120. At the same time, the control module 2 controls the heating device 10 to start, and continuously heats the internal cavity of the reaction barrel 4. As the mounting bracket 113 rises, the mounting bracket 113 drives the circular slide rail 124 and the sliding bracket 125 to rise synchronously through the connection between the feed box 115 and the discharge pipe 126, and at the same time, the end of the discharge pipe 126 located inside the mixing barrel 120 is always located above the liquid level in the mixing barrel 120; When the ethyl acetate production raw material mixed liquid completely enters the stirring barrel 120, the control module 2 controls the first motor 6 to turn off, so that the rotating base 7, the electric push rod 8, the mounting base 9, the electric slide rail 111, the sliding base 112 and the mounting bracket 113 stop rotating, and then the control module 2 controls the solenoid valve 121 at the bottom of the stirring barrel 120 to open, so that the ethyl acetate production raw material mixed liquid in the stirring barrel 120 enters the reaction barrel 4, and the ethyl acetate production raw material mixed liquid in the reaction barrel 4 and the ethyl acetate production raw material mixed liquid in the stirring barrel 120 reach liquid level equilibrium, and then the ethyl acetate production raw material mixed liquid in the reaction barrel 4 and the stirring barrel 120 are continuously heated by the heating device 10, so that the ethyl acetate production raw material mixed liquid generates ethyl acetate vapor, and the generated ethyl acetate vapor is introduced into the condensing device through the air outlet 50 at the top of the protective cover 5 for subsequent further processing; When the mixed liquid of ethyl acetate production raw materials in the reaction barrel 4 and the stirring barrel 120 is completely reacted, the control module 2 controls the electric push rod 8 to start again. After the electric push rod 8 is started, it pushes the installation base plate 9 to slide downward. While the installation base plate 9 slides, the electric slide rail 111 and the sliding base 112 drive the installation bracket 113 to slide downward synchronously. Since the feed box 115 and the discharge pipe 126 are in a connected state at this time, when the installation bracket 113 slides, it drives the circular slide rail 124 and the sliding bracket 125 to slide downward synchronously.

[0034] By setting up a stirring barrel 120 and a stirring plate 123, the ethyl acetate production raw material liquid in the stirring barrel 120 is mixed and stirred. At the same time, the linkage effect of the circular slide rail 124 and the sliding bracket 125 is cooperated to ensure that when the collaborative component 14 cleans the inner wall of the reaction barrel 4, the port at one end of the discharge pipe 126 located inside the stirring barrel 120 is always located above the liquid level in the stirring barrel 120, thereby avoiding the bottom part of the discharge pipe 126 from being contaminated with the ethyl acetate production raw material liquid, resulting in waste of ethyl acetate production raw materials.

[0035] like Figures 10 and 11 As shown, the switching assembly 13 includes an upper clamping column 131, which is installed on one side of the surface of the discharge tube 126, and a lower clamping column 132 is sleeved on the surface of the cylindrical part of the upper clamping column 131. The number of the upper clamping column 131 and the lower clamping column 132 is set to multiple groups, and the multiple groups of upper clamping columns 131 and lower clamping columns 132 are arranged at equal angles in a circular array on the side of the discharge tube 126. The switching assembly 13 also includes a positioning ring 133, and the number of the positioning rings 133 is set to multiple groups. The multiple groups of positioning rings 133 are installed at the bottom edge of the feed box 115 in a circular array. A wedge 134 is nested on the inner wall of the positioning ring 133, and one end of the wedge 134 is elastically connected to the inner wall of the positioning ring 133 by a spring 135. The inclination angle of the inclined surface at one end of the wedge 134 is consistent with the inclination angle of the surface of the upper clamping column 131 and the lower clamping column 132.

[0036] At the same time, when the mounting bracket 113 drives the feed box 115 to slide, the sliding of the feed box 115 drives the positioning ring 133 to slide synchronously, so that the positioning ring 133 slides close to the upper clamping column 131. At the same time, under the continuous sliding action of the positioning ring 133, the inclined surface of the wedge block 134 on the inner wall of the positioning ring 133 is close to and contacts the top surface of the upper clamping column 131. Under the continuous sliding action of the positioning ring 133, the force after the contact between the upper clamping column 131 and the inclined surface of the wedge block 134 causes the wedge block 134 to slide horizontally on the inner wall of the positioning ring 133. When the wedge block 134 slides, the spring 135 is squeezed to contract. The cam 134 is pressed against the bottom end of the upper post 131 and the cam 136 is released, and the cam 137 is released to the left and right, and the cam 138 is released to the right and the cam 139 is released. When the circular slide rail 124 slides to the convex groove at the bottom edge of the mixing barrel 120, under the contact force between the convex groove and the circular slide rail 124, the circular slide rail 124, the sliding bracket 125 and the discharge pipe 126 stop sliding. At this time, the mounting bracket 113 drives the feed box 115 and the positioning ring 133 to continue sliding. While the positioning ring 133 slides, it drives the wedge 134 to contact the edge of the lower clamping column 132, and under the action of the contact force with the lower clamping column 132, the wedge 134 slides. While the wedge 134 slides, it drives the spring 135 to contract. When the wedge 134 passes the widest position of the cross section of the lower clamping column 132, the elastic action of the spring 135 resets the direction of sliding. At this time, the wedge 134 is located at the bottom of the lower clamping column 132. Then the electric push rod 8 stops pushing the installation base plate 9 to slide downward, and drives the installation base plate 9 to slide upward and reset, so that the installation bracket 113 drives the feed box 115 and the positioning ring 133 to slide upward. While the positioning ring 133 slides, it drives the wedge block 134 to contact the bottom end surface of the lower clamping column 132, and drives the lower clamping column 132 to slide upward along the cylindrical part of the upper clamping column 131. When the lower clamping column 132 slides into place, the top surface of the lower clamping column 132 is completely in contact with the bottom surface of the upper clamping column 131 and is blocked by the upper clamping column 131. Under the continuous sliding action of the positioning ring 133 When the wedge 134 is in contact with the upper clamping column 131, the spring 135 is unloaded and reset. At this time, the connection between the feed box 115 and the discharge pipe 126 is realized, and the circular slide rail 124 and the sliding bracket 125 are located at the bottom end of the mixing barrel 120. Subsequently, the electric push rod 8 drives the mounting base 9, the electric slide rail 111, the sliding base 112 and the mounting bracket 113 to continue to slide upward and reset, and return to the initial position. Then the control module 2 controls the robotic arm 3 to drive the protective cover 5 out of contact with the reaction barrel 4 again.

[0037] By specially designing the cross-sectional shapes of the upper clamping column 131 and the lower clamping column 132, and coordinating the elastic cooperation between the wedge block 134 and the spring 135, the limiting and releasing effects of the wedge block 134 are achieved, thereby realizing the switching of the connection mode between the feed box 115 and the discharge pipe 126, and realizing the rapid mechanical locking of the feed box 115 and the discharge pipe 126.

[0038] like Figures 12 to 14 As shown, the cooperative component 14 includes a cleaning nozzle 141, which is mounted on the top of one side of the mounting bracket 113, and a portion of the surface of the cleaning nozzle 141 is nested and mounted on the inner wall of the rotating base 7. The cooperative component 14 also includes a cleaning roller 142, which is mounted at the edge of one end of the mounting bracket 113. A sponge cleaning block 143 is mounted on the surface of the cleaning roller 142 by bolts. The sponge cleaning blocks 143 are arranged in a circular array on the surface of the cleaning roller 142. The sponge material of the sponge cleaning block 143 is set to polyester sponge. An extrusion plate 144 is mounted on the inner wall of the mounting bracket 113, and a plurality of groups of guide grooves 145 are arranged in an array on the surface of the extrusion plate 144. A collecting tray 146 is mounted on the bottom end of the mounting bracket 113, and a suction pipe 147 is connected to the bottom end of the collecting tray 146. The suction pipe 147 is mounted on one side of the bottom end of the mounting bracket 113, and a portion of the surface of the suction pipe 147 is nested and mounted on the inner wall of the rotating base 7.

[0039] As the mounting bracket 113 rotates, the feed box 115 is driven to rotate synchronously. At the same time, the connection between the feed box 115 and the discharge pipe 126 causes the discharge pipe 126 to rotate synchronously with the feed box 115. As the discharge pipe 126 rotates, the sliding bracket 125 is driven to rotate on the outer surface of the circular slide rail 124. During this process, the operator also uses a water pump device to pump cleaning agent into the cleaning nozzle 141, and the cleaning agent is continuously sprayed through the cleaning nozzle 141, and the sprayed cleaning agent adheres to the sponge cleaning block 143. Under the rotation of the mounting bracket 113, the sponge cleaning blocks 143 on the surface of the cleaning roller 142 come into contact with the inner wall of the reaction barrel 4. Under the action of the friction force generated by the contact between the sponge cleaning blocks 143 and the inner wall of the reaction barrel 4, the cleaning roller 142 rotates on the inner wall of the mounting bracket 113. When the cleaning roller 142 rotates, the multiple groups of sponge cleaning blocks 143 are driven to rotate synchronously. The inner wall of the reaction barrel 4 is cleaned by the rotation effect of the sponge cleaning blocks 143 and the attached cleaning agent. At the same time, the inner wall of the reaction barrel 4 is cleaned in a circular manner in conjunction with the rotation effect of the mounting bracket 113. Under the rotation of the cleaning roller 142, the multiple groups of sponge cleaning blocks 143 are rotated in sequence to contact the inner wall of the reaction barrel 4. At the same time, the multiple groups of sponge cleaning blocks 143 that have contacted the inner wall of the reaction barrel 4 are rotated to contact the squeezing plate 144. Since one end of the squeezing plate 144 contacts and squeezes the multiple groups of sponge cleaning blocks 143, when the cleaning roller 142 drives the multiple groups of sponge cleaning blocks 143 to rotate through the squeezing plate 144, the sewage adsorbed by the sponge cleaning blocks 143 is squeezed out through the squeezing action of the squeezing plate 144, and the squeezed sewage is diverted through the multiple groups of guide grooves 145 on the surface of the squeezing plate 144. Under the action of gravity, the sewage falls into the collection tray 146. During the process, the operator continuously sucks the suction pipe 147 through the water pump equipment, so that the sewage collected in the collection tray 146 is continuously extracted through the suction pipe 147. When multiple groups of sponge cleaning blocks 143 perform circular cleaning on the inner wall of the reaction barrel 4, the control module 2 controls the electric push rod 8 to start. After the electric push rod 8 is started, it pulls the mounting base 9 to slide upward. While the mounting base 9 slides, the mounting bracket 113 is driven to slide upward synchronously through the electric slide rail 111 and the sliding base 112. At this time, the rotating base 7 is still in a rotating state. Under the rotation action of the rotating base 7 and the sliding action of the mounting base 9, the mounting bracket 113 rotates and rises at the same time. Under the movement action of the mounting bracket 113, the sponge cleaning block 143 realizes the cleaning effect of the inner wall of the reaction barrel 4. At the same time, the heating effect of the heating device 10 is used to heat and dry the cleaned inner wall of the reaction barrel 4.

[0040] By setting the rotation effect of the cleaning roller 142 and the sponge cleaning block 143, the cleaning effect of the inner wall of the reaction barrel 4 is achieved. By utilizing the corrosion-resistant and high-temperature-resistant properties of the polyester sponge, the service life of the sponge cleaning block 143 is improved while ensuring the cleaning effect of the sponge cleaning block 143 on the inner wall of the reaction barrel 4. At the same time, in conjunction with the spraying and suction effects of the cleaning nozzle 141 and the suction pipe 147, the synchronous operation of the cleaning and recovery functions of the collaborative component 14 is achieved.

[0041] The working principle of the technical solution provided by the present invention is as follows: The operator first starts the robotic arm 3 through the control module 2. After the robotic arm 3 is started, it drives the protective cover 5 close to the reaction barrel 4, so that the outer surface of the protective cover 5 contacts the inner wall of the reaction barrel 4 and is sealed. Then, the control module 2 controls the electric slide rail 111 to start. Under the action of the electric slide rail 111, the sliding base 112 mounted on the surface of the electric slide rail 111 slides along the direction of the electric slide rail 111. When the sliding base 112 slides, it drives the mounting bracket 113 to slide synchronously. When the mounting bracket 113 slides, it drives the feeding box 115 to slide synchronously, so that the bottom center of the feeding box 115 and the center of the discharge pipe 126 are located in the same axial direction. At this time, the port at one end of the discharge pipe 126 is located inside the mixing barrel 120 and is located at the bottom of the inner wall of the mixing barrel 120. At the same time, the circular slide rail 124 is located at the bottom of the outer surface of the mixing barrel 120.

[0042] Subsequently, the control module 2 controls the electric push rod 8 to start. After the electric push rod 8 is started, it pushes the installation base plate 9 to slide downward. While the installation base plate 9 slides, the installation bracket 113 is driven to slide downward synchronously through the electric slide rail 111 and the sliding base 112. While the installation bracket 113 slides, it drives the feed box 115 at the bottom to slide downward synchronously. While the feed box 115 slides, it gradually approaches the inner wall of one end of the discharge pipe 126, and makes the sealing gasket 116 on the surface of the extended part of the bottom end of the feed box 115 contact with the sealing gasket ring 127, so that the surface of the sealing gasket 116 is in close contact with the inner wall of the sealing gasket ring 127.

[0043] At the same time, the mounting bracket 113 drives the feed box 115 to slide, and the sliding of the feed box 115 drives the positioning ring 133 to slide synchronously, so that the positioning ring 133 slides close to the upper clamping column 131. At the same time, under the continuous sliding action of the positioning ring 133, the inclined surface of the wedge block 134 on the inner wall of the positioning ring 133 is close to and contacts the top surface of the upper clamping column 131. Under the continuous sliding action of the positioning ring 133, the force after the contact between the upper clamping column 131 and the inclined surface of the wedge block 134 causes the wedge block 134 to slide horizontally on the inner wall of the positioning ring 133. When the wedge block 134 slides, the spring 135 is squeezed to contract.

[0044] Under the continuous sliding action of the positioning ring 133, the inclined surface of the wedge block 134 contacts the surface of the upper clamping column 131 and slides, and disengages from the surface of the upper clamping column 131 and enters the gap between the upper clamping column 131 and the lower clamping column 132. At this time, since the force after the contact between the upper clamping column 131 and the inclined surface of the wedge block 134 disappears, the spring 135 stretches under the action of elasticity, causing the wedge block 134 to slide horizontally in the opposite direction on the inner wall of the positioning ring 133 and reset. As the wedge block 134 slides, the top surface of the wedge block 134 contacts the bottom end of the upper clamping column 131, thereby forming a limit between the wedge block 134 and the upper clamping column 131, so that a connection is formed between the feed box 115 and the discharge pipe 126. At this time, the control module 2 controls the electric push rod 8 to stop.

[0045] Subsequently, the control module 2 controls the first motor 6 to start, and after the first motor 6 starts, it drives the rotating base 7 to rotate synchronously. When the rotating base 7 rotates, it drives the electric push rod 8, the mounting base 9, the electric slide rail 111, the sliding base 112 and the mounting bracket 113 to rotate synchronously. At the same time, the operator sequentially pumps the ethyl acetate production raw material into the feed pipe 114 through the water pump equipment, so that the ethyl acetate production raw material enters the discharge pipe 126 through the feed pipe 114, and continuously enters the mixing barrel 120 through the discharge pipe 126; When the ethyl acetate production raw materials enter the stirring barrel 120, the control module 2 controls the second motor 122 to start, and under the action of the second motor 122, the stirring barrel 120 rotates. While the stirring barrel 120 rotates, it drives the multiple groups of stirring plates 123 on the inner wall to rotate synchronously, and fully stirs the ethyl acetate production raw material mixed liquid in the stirring barrel 120. At the same time, the control module 2 controls the heating device 10 to start, and continuously heats the internal cavity of the reaction barrel 4.

[0046] When the mounting bracket 113 rotates, the feed box 115 is driven to rotate synchronously. At the same time, through the connection between the feed box 115 and the discharge pipe 126, the discharge pipe 126 is caused to rotate synchronously with the feed box 115. When the discharge pipe 126 rotates, the sliding bracket 125 is driven to rotate on the outer surface of the circular slide rail 124. During this process, the operator also uses a water pump equipment to pump cleaning agent into the cleaning nozzle 141, and the cleaning agent is continuously sprayed out through the cleaning nozzle 141, and the sprayed cleaning agent adheres to the sponge cleaning block 143.

[0047] Under the rotation of the mounting bracket 113, the sponge cleaning block 143 on the surface of the cleaning roller 142 contacts the inner wall of the reaction barrel 4. Under the action of the friction force generated by the contact between the sponge cleaning block 143 and the inner wall of the reaction barrel 4, the cleaning roller 142 rotates on the inner wall of the mounting bracket 113. When the cleaning roller 142 rotates, it drives multiple groups of sponge cleaning blocks 143 to rotate synchronously. The inner wall of the reaction barrel 4 is cleaned by the rotation effect of the sponge cleaning block 143 and the attached cleaning agent. At the same time, the inner wall of the reaction barrel 4 is cleaned in an annular manner in conjunction with the rotation effect of the mounting bracket 113.

[0048] Under the rotation action of the cleaning roller 142, the multiple groups of sponge cleaning blocks 143 are rotated in turn to contact the inner wall of the reaction barrel 4, and at the same time, the multiple groups of sponge cleaning blocks 143 after contacting the inner wall of the reaction barrel 4 are rotated to contact the squeezing plate 144. Since one end of the squeezing plate 144 contacts and squeezes the multiple groups of sponge cleaning blocks 143, when the cleaning roller 142 drives the multiple groups of sponge cleaning blocks 143 to rotate through the squeezing plate 144, the sewage adsorbed by the sponge cleaning blocks 143 is squeezed out through the squeezing action of the squeezing plate 144, and the squeezed sewage is diverted through the multiple groups of guide grooves 145 on the surface of the squeezing plate 144, and under the action of gravity, the sewage falls into the collection tray 146. During the process, the operator continuously sucks the suction pipe 147 through the water pump equipment, so that the sewage collected in the collection tray 146 is continuously extracted through the suction pipe 147.

[0049] When multiple groups of sponge cleaning blocks 143 perform circular cleaning on the inner wall of the reaction barrel 4, the control module 2 controls the electric push rod 8 to start. After the electric push rod 8 is started, it pulls the mounting base 9 to slide upward. While the mounting base 9 slides, the mounting bracket 113 is driven to slide upward synchronously through the electric slide rail 111 and the sliding base 112. At this time, the rotating base 7 is still in a rotating state. Under the rotation action of the rotating base 7 and the sliding action of the mounting base 9, the mounting bracket 113 rotates and rises at the same time. Under the movement action of the mounting bracket 113, the sponge cleaning block 143 realizes the cleaning effect of the inner wall of the reaction barrel 4. At the same time, the heating effect of the heating device 10 is used to heat and dry the cleaned inner wall of the reaction barrel 4.

[0050] As the mounting bracket 113 rises, the mounting bracket 113 drives the circular slide rail 124 and the sliding bracket 125 to rise synchronously through the connection between the feed box 115 and the discharge pipe 126, and at the same time, the port at one end of the discharge pipe 126 located inside the mixing barrel 120 is always located above the liquid level in the mixing barrel 120.

[0051] When the mixed liquid of ethyl acetate production raw materials completely enters the stirring barrel 120, the control module 2 controls the first motor 6 to turn off, so that the rotating base 7, the electric push rod 8, the mounting base 9, the electric slide rail 111, the sliding base 112 and the mounting bracket 113 stop rotating, and then the control module 2 controls the solenoid valve 121 at the bottom end of the stirring barrel 120 to open, so that the mixed liquid of ethyl acetate production raw materials in the stirring barrel 120 enters the reaction barrel 4, and the mixed liquid of ethyl acetate production raw materials in the reaction barrel 4 and the mixed liquid of ethyl acetate production raw materials in the stirring barrel 120 reach liquid level equilibrium, and then the heating device 10 continuously heats the mixed liquid of ethyl acetate production raw materials in the reaction barrel 4 and the stirring barrel 120, so that the mixed liquid of ethyl acetate production raw materials generates ethyl acetate vapor, and the generated ethyl acetate vapor is introduced into the condensation device through the air outlet 50 at the top of the protective cover 5 for subsequent further processing.

[0052] When the mixed liquid of ethyl acetate production raw materials in the reaction barrel 4 and the stirring barrel 120 is completely reacted, the control module 2 controls the electric push rod 8 to start again. After the electric push rod 8 is started, it pushes the installation base plate 9 to slide downward. While the installation base plate 9 slides, the electric slide rail 111 and the sliding base 112 drive the installation bracket 113 to slide downward synchronously. Since the feed box 115 and the discharge pipe 126 are in a connected state at this time, when the installation bracket 113 slides, it drives the circular slide rail 124 and the sliding bracket 125 to slide downward synchronously.

[0053] When the circular slide rail 124 slides to the convex groove at the bottom edge of the mixing barrel 120, under the contact force between the convex groove and the circular slide rail 124, the circular slide rail 124, the sliding bracket 125 and the discharge pipe 126 stop sliding. At this time, the mounting bracket 113 drives the feed box 115 and the positioning ring 133 to continue sliding. While the positioning ring 133 slides, it drives the wedge block 134 to contact the edge of the lower clamping column 132, and under the action of the contact force with the lower clamping column 132, the wedge block 134 slides. While the wedge block 134 slides, it drives the spring 135 to contract. When the wedge block 134 passes the widest position of the cross-section of the lower clamping column 132, the direction of the sliding is reset under the elastic action of the spring 135. At this time, the wedge block 134 is located at the bottom of the lower clamping column 132.

[0054] Then the electric push rod 8 stops pushing the installation base plate 9 to slide downward, and drives the installation base plate 9 to slide upward and reset, so that the installation bracket 113 drives the feed box 115 and the positioning ring 133 to slide upward. While the positioning ring 133 slides, it drives the wedge block 134 to contact the bottom end surface of the lower clamping column 132, and drives the lower clamping column 132 to slide upward along the cylindrical part of the upper clamping column 131. When the lower clamping column 132 slides into place, the top surface of the lower clamping column 132 is completely in contact with the bottom surface of the upper clamping column 131 and is blocked by the upper clamping column 131. Under the continuous sliding action of the positioning ring 133 When the wedge 134 is used, it first slides along the surface of the lower clamping column 132. While the wedge 134 slides, the spring 135 is squeezed and contracted. When the wedge 134 reaches the widest part of the cross-section of the lower clamping column 132, the inclined surface of the wedge 134 contacts the inclined surface of the upper clamping column 131 and slides. At the same time, the lower clamping column 132 slides along the cylindrical part of the upper clamping column 131. While the wedge 134 contacts the inclined surface of the upper clamping column 131 and slides, it drives the spring 135 to unload the force and reset. At this time, the connection between the feed box 115 and the discharge pipe 126 is in the form of a circular slide rail 124 and a sliding bracket 125 located at the bottom end of the mixing barrel 120.

[0055] Subsequently, the electric push rod 8 drives the mounting base 9, the electric slide rail 111, the sliding base 112 and the mounting bracket 113 to continue to slide upward and reset, and return to the initial position. Then the control module 2 controls the robotic arm 3 to drive the protective cover 5 out of contact with the reaction barrel 4 again.
