[0001] The present invention relates to the technical field of reaction kettles, and specifically to a cleaning system for a potassium tert-butoxide production reaction kettle. Background Art

[0002] Potassium tert-butoxide is widely used in organic synthesis fields such as chemical industry, medicine, and pesticides.

[0003] The potassium tert-butoxide production reaction kettle is a key equipment for the efficient and safe production of potassium tert-butoxide. Metal potassium is added to tert-butanol in the reaction kettle, and through heating and stirring, a displacement reaction occurs between metal potassium and tert-butanol, thereby generating potassium tert-butoxide.

[0004] During the production process of potassium tert-butoxide, in order to prevent cross-contamination of different batches of products, ensure the stable quality of products, and at the same time avoid the influence of residues on the reaction efficiency and product purity, after the reaction kettle completes the production of one batch of potassium tert-butoxide, the cleaning of the reaction kettle is an important link to ensure product quality and equipment safety. The existing method for cleaning the reaction kettle is to soak the inside of the kettle with a large amount of clean water and add a certain amount of cleaning agent to achieve a better cleaning effect.

[0009] Furthermore, air inlets are formed on one side of the top of the two bridging plates. The air inlets communicate with the cavity of the sliding plate. A connecting pipe is fixedly installed on the outside of the top of the air inlets. The other end of the air outlet pipe is fixedly connected to the connecting pipe.

[0010] Furthermore, the reciprocating assembly includes an electric push rod. The output shaft of the electric push rod is fixedly connected with a fixing plate.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Please refer to Figures 1 - 10 , a cleaning system for a potassium tert-butoxide production reactor, including a reactor body 1, a mounting frame 2 connected to the top of the reactor body 1, a stirring drive unit 3 connected to the mounting frame 2, and a stirring structure 11 connected to the lower end of the stirring drive unit 3. Two semi-circular covers 4 are connected to the top of the reactor body 1. The two semi-circular covers 4 are respectively located on both sides of the mounting frame 2. A sliding plate 13 is slidably connected inside the two semi-circular covers 4. An airbag 15 is fixedly connected to the inner wall of the sliding plate 13. A cavity 14 is formed between the airbag 15 and the inner wall of the sliding plate 13. A pulling member is connected inside the cavity 14. An inflation assembly is connected to the top of the two semi-circular covers 4. The airbag 15 is inflated through the inflation assembly. A reciprocating assembly is connected to the top of the semi-circular cover 4; The inflation assembly includes a blower 20. The blower 20 is fixedly installed on the top of the mounting frame 2. The outer side of the air outlet of the blower 20 is fixedly connected with an air outlet pipe 25. Two symmetrically arranged air outlet pipes 6 are fixedly connected to the outer side of the air outlet pipe 25. The other end of the air outlet pipe 6 is communicated with the cavity 14 inside the sliding plate 13; The pulling member includes two groups of pull ropes 29. The two groups of pull ropes 29 are provided in multiple numbers. One end of the pull rope 29 is fixedly connected to the inner wall of the airbag 15, and the other end is fixedly connected to the inner wall of the cavity 14.

[0021] In the cleaning system of the potassium tert-butoxide production reactor of the present invention, when the reactor body 1 needs to be cleaned, first, the sliding plate 13 is lowered into the reactor body 1 through the reciprocating assembly, so that the bottom surface of the sliding plate 13 is located above the bottom surface of the inner wall of the reactor body 1, ensuring that the bottom surface of the sliding plate 13 does not contact the bottom surface of the inner wall of the reactor body 1, so as to ensure that the cleaning water can fully contact the inner wall of the reactor body 1 and the stirring structure 11; At this time, start the inflation assembly to inflate the cavity 14 inside the sliding plate 13, so that the airbag 15 is filled and bulges, filling the reactor body 1. At this time, affected by the inflated airbag 15, the volume of the reactor body 1 is reduced; At this time, add cleaning water. The cleaning water can be added through an external pipeline. Since the volume inside the reactor body 1 is reduced due to the filling of the two airbags 15, the amount of cleaning water added can be reduced, so that the reactor body 1 can be soaked with the least amount of water, saving water resources while reducing the amount of water added, thereby reducing the water addition time and further improving the work efficiency and cleaning efficiency.

[0022] After the soaking is completed, the soaked sewage can be discharged through the drain outlet of the reaction kettle body 1. During the discharging process, the sewage can be filtered and recycled by the water resource recovery equipment to further achieve the purpose of saving water resources.

[0023] When the airbag 15 needs to be inflated, the fan 20 can be started. The fan 20 draws in air through its own air inlet, and sends the air through the air outlet pipe 25 and the air delivery pipe 6 into the airbag 15 to inflate the airbag 15 and make it bulge. When deflation is needed, only the fan blades of the fan 20 need to rotate in the reverse direction to suck air from the airbag 15 to complete the deflation operation, and then the airbag 15 can be deflated.

[0024] In order to mix the cleaning water during the soaking process, the stirring drive unit 3 can drive the stirring structure 11 to stir in the reaction kettle body 1 to mix the cleaning water. In order to prevent the bulging of the airbag 15 from restricting the rotation of the stirring structure 11, when the airbag 15 bulges, several groups of ropes 29 will pull the airbag 15, making the cross-section of the airbag 15 form several arc shapes. Thus, when the airbag 15 bulges, it will not hinder the rotation of the stirring structure 11, so that the cleaning water can be stirred, thereby improving the soaking effect.

[0025] As a preferred technical solution of the present invention, a bridging plate 5 is fixedly connected to the top of the sliding plate 13. Semi-circular arc grooves 12 are formed on the two semi-circular arc cover plates 4. The sliding plate 13 is slidably connected within the semi-circular arc grooves 12, and the bottom surface of the bridging plate 5 is in contact with the top surface of the semi-circular arc cover plate 4.

[0026] Specifically, in order to prevent the sliding plate 13 from affecting the normal use of the reaction kettle body 1, the reciprocating assembly can be used to raise the sliding plate 13 so that the sliding plate 13 slides in the semi-circular arc grooves 12 of the semi-circular arc cover plate 4 to ensure the normal use of the reaction kettle body 1.

[0027] As a preferred technical solution of the present invention, air inlets 26 are formed on one side of the top of the two bridging plates 5. The air inlets 26 are communicated with the cavity 14 of the sliding plate 13. A connecting pipe 21 is fixedly installed on the outer side of the top of the air inlets 26, and the other end of the air delivery pipe 6 is fixedly connected to the connecting pipe 21.

[0028] Specifically, when the air delivery pipe 6 discharges air, the air will be sent into the air inlets 26 through the connecting pipe 21 and then into the cavity 14 to make the airbag 15 bulge normally.

[0029] As a preferred technical solution of the present invention, the reciprocating assembly includes an electric push rod 10. The output shaft of the electric push rod 10 is fixedly connected to a fixed plate 17. Two symmetrically arranged vertical rods 18 are fixedly connected to both sides of the bottom of the fixed plate 17. A connecting cross plate 23 is fixedly connected between the two ends of the two carrying plates 5. The bottom parts of the two groups of vertical rods 18 are respectively fixedly connected to the top of the connecting cross plate 23. A support structure is connected to the outside of the electric push rod 10.

[0030] Specifically, after the soaking and cleaning of the reactor body 1 are completed, the electric push rod 10 can be started, so that the output end of the electric push rod 10 drives the fixed plate 17. The fixed plate 17 will drive the vertical rods 18 at both ends, causing it to lift the connecting cross plate 23 between the two carrying plates 5, and then drive the two sliding plates 13 to move upward in the semi-circular grooves 12. When the sliding plate 13 needs to be lowered, only the output shaft of the electric push rod 10 needs to be pushed in the reverse direction to realize the lowering of the sliding plate 13.

[0031] As a preferred technical solution of the present invention, the support structure includes a mounting plate 9. The electric push rod 10 is fixedly installed on the mounting plate 9. Cross rods 8 are fixedly connected to both sides of the mounting plate 9. Two symmetrically arranged U-shaped rods 7 are fixedly connected to the semi-circular cover plate 4. The two ends of the two cross rods 8 are respectively fixedly connected to the top of the U-shaped rods 7. A support plate 19 is fixedly connected between the two relatively arranged U-shaped rods 7.

[0032] Specifically, in order to ensure the stability of the electric push rod 10 during operation, the two U-shaped rods 7 are fixedly installed on the outer wall of the semi-circular cover plate 4 and are simultaneously supported by the ground. A cross rod 8 is connected between the two U-shaped rods 7. The mounting plate 9 is installed between the cross rods 8. The mounting plate 9 is used to install the electric push rod 10, thus ensuring the stability of the electric push rod 10 during operation.

[0033] As a preferred technical solution of the present invention, two symmetrically arranged balance rods 16 are fixedly connected to the top of the fixed plate 17. A balance chute 22 is provided through the mounting plate 9. The balance rods 16 are slidably connected to the balance chute 22.

[0034] Specifically, in order to ensure the stability of the fixed plate 17 when it rises and falls, when the fixed plate 17 moves up and down, the two balance rods 16 will move in the balance chute 22 in the mounting plate 9, thereby ensuring the stability of the fixed plate 17 when it moves up and down.

[0035] As a preferred technical solution of the present invention, an L-shaped plate 24 is fixedly connected to the top of the mounting frame 2. The fan 20 is fixedly installed on the L-shaped plate 24.

[0036] Specifically, the setting of the L-shaped plate 24 facilitates the stable installation of the fan 20.

[0037] As a preferred technical solution of the present invention, a wear-resistant layer 27 is fixedly connected to the outer wall of the airbag 15, and a plurality of wear-resistant strips 28 are fixedly connected to the outer wall of the wear-resistant layer 27. When selecting the material of the airbag 15, a material with strong corrosion resistance, such as polytetrafluoroethylene, can be selected to ensure its stability during the production process of potassium tert-butoxide.

[0038] Specifically, through the arrangement of the wear-resistant layer 27 and the wear-resistant strips 28, the service life of the airbag 15 can be extended.

[0039] In the above structure, the fan 20 and the electric push rod 10 are existing mature technologies, including the functions of the fan 20 to inflate and deflate, which are all existing mature technologies, so no more details will be described here.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
