Specific embodiments

[0020] The following further details the present application with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related utility model, rather than limiting the utility model. Additionally, it should be noted that for the sake of description, only the parts related to the utility model are shown in the drawings.

[0021] In the drawings of the embodiments of the present utility model: Different types of hatching lines in the figure are not marked according to the national standard, nor are the materials of the components required. They are used to distinguish the cross-sectional views of the components in the figure.

[0022] Please refer to Figure 1-6 , a corrosion-resistant glass-lined reaction kettle, including a reaction kettle body 1, a reaction kettle cover 2 fixedly installed on the top of the reaction kettle body 1, and a driving motor 3 and a stirrer 4 fixedly installed on the reaction kettle cover 2. A first connecting pipe 5 and a second connecting pipe 6 are arranged on the outer side of the reaction kettle cover 2. A first piston cylinder 7 and a second piston cylinder 8 are respectively fixedly installed on the tops of the first connecting pipe 5 and the second connecting pipe 6. Through the cooperation of the first connecting pipe 5 and the second connecting pipe 6, the pneumatic driving components related to the cleaning mechanism 10 can be installed above the reaction kettle cover 2, thereby ensuring that the pneumatic driving components will not be immersed in the reaction solution during the use of the glass-lined reaction kettle. Piston rods 9 with their bottom ends extending to the inner side of the reaction kettle cover 2 are movably sleeved inside the first piston cylinder 7 and the second piston cylinder 8. A cleaning mechanism 10 sleeved on the inner side of the reaction kettle body 1 is fixedly sleeved on the outer side of the bottom end of the piston rod 9. A pneumatic driving mechanism 11 communicating with the first piston cylinder 7 and the second piston cylinder 8 is fixedly installed on the top of the driving motor 3.

[0023] Among them, the inner diameters of the first connecting pipe 5 and the second connecting pipe 6 are smaller than those of the first piston cylinder 7 and the second piston cylinder 8. By adopting this structure, when the cleaning mechanism 10 descends to the lowest point, the first connecting pipe 5 and the second connecting pipe 6 can automatically limit and support the piston rod 9, so that the cleaning mechanism 10 will not continue to move downward, avoiding damage to the protrusion 103. When the cleaning mechanism 10 is at the highest point, the top of the sealing plate 12 contacts the bottom end faces of the first connecting pipe 5 and the second connecting pipe 6. At this time, the first piston cylinder 7 and the second piston cylinder 8 can be sealed to prevent the gas generated inside the glass-lined reactor from leaking to the outside through the first connecting pipe 5 and the second connecting pipe 6.

[0024] Among them, the cleaning mechanism 10 includes a cleaning ring 101 fixedly sleeved on the outer side of the bottom end of the piston rod 9. A cleaning rubber ring 102 sleeved on the outer side of the cleaning ring 101 is sleeved inside the reactor body 1. A protrusion 103 clamped on the inner side of the outer side of the cleaning ring 101 is arranged on the inner side of the cleaning rubber ring 102. The material attached to the inner wall of the reactor body 1 can be cleaned by the movement of the cleaning rubber ring 102, and the cleaning rubber ring 102 is driven pneumatically, so that the cleaning rubber ring 102 is not easily stuck inside the reactor body 1.

[0025] Among them, the pneumatic driving mechanism 11 includes an electromagnetic directional valve 111 fixedly installed on the top of the driving motor 3. The inside of the electromagnetic directional valve 111 is communicated with a first air pipe 112, a second air pipe 113, a negative pressure pipe 114 and a high-pressure pipe 115. The bottom end of the first air pipe 112 is communicated with the inside of the top of the first piston cylinder 7. The bottom end of the second air pipe 113 is communicated with the inside of the top of the second piston cylinder 8. The negative pressure pipe 114 is communicated with a negative pressure source, and the high-pressure pipe 115 is communicated with a high-pressure source. By driving the electromagnetic directional valve 111, the high-pressure source and the negative pressure source can be switched and the moving direction of the piston rod 9 can be changed, so as to realize the automatic lifting of the cleaning mechanism 10.

[0026] Among them, a sealing plate 12 is arranged on the outer side of the bottom end of the piston rod 9 and is located below the first connecting pipe 5 and the second connecting pipe 6. By contacting the first connecting pipe 5 and the second connecting pipe 6 with the sealing plate 12, the first connecting pipe 5 and the second connecting pipe 6 can be shielded and sealed to prevent the gas inside the enamel reactor from leaking to the outside.

[0027] When cleaning the inner wall of the reaction kettle body 1, the electromagnetic reversing valve 111 is switched to connect the high-pressure pipe 115. At this time, the high-pressure gas inside the high-pressure pipe 115 is transported to the inside of the first piston cylinder 7 and the second piston cylinder 8 through the first air pipe 112 and the second air pipe 113. Then, under the action of the gas pressure, the piston rod 9 and the cleaning mechanism 10 are pushed to move downward synchronously. While the cleaning mechanism 10 moves downward, the attached materials on the inner wall of the reaction kettle body 1 are cleaned by the cleaning rubber ring 102. And when the cleaning rubber ring 102 moves to the lowest point, the piston rod 9 contacts the first connecting pipe 5 and the second connecting pipe 6. At this time, the first connecting pipe 5 and the second connecting pipe 6 are used for limiting. The electromagnetic reversing valve 111 is switched to connect the negative-pressure pipe 114. At this time, the inside of the first piston cylinder 7 and the second piston cylinder 8 is evacuated through the negative-pressure pipe 114, the first air pipe 112 and the second air pipe 113. Then, under the action of the air pressure difference, the piston rod 9 and the cleaning mechanism 10 are pushed to reset. When the cleaning mechanism 10 moves to the highest point, the sealing plate 12 contacts the bottoms of the first connecting pipe 5 and the second connecting pipe 6, and the first connecting pipe 5 and the second connecting pipe 6 are sealed by the piston rod 9, completing the cleaning of the inner wall of the reaction kettle body 1.
