Description

Technical Field

[0001] The utility model relates to the technical field of oilfield chemical additive production, in particular to a reaction kettle heating device in oilfield chemical additive production. Background Art

[0002] In recent years, oil fields have mostly adopted chemical flooding to improve crude oil recovery, which has led to increasingly serious scaling problems. In the various processes of oil extraction and refining, a variety of additives need to be used to improve process conditions and increase production efficiency. In the production of chemical additives, reactors are often used to ensure the stability of the reaction:

[0003] When a reactor for preparing chemical additives is currently heated, the heating position is fixed, resulting in uneven heating of the raw materials in the reactor. When the temperature at a certain point inside the reactor is not reached, the reaction efficiency of the raw materials at that point is likely to be low. At the same time, in order to improve the reaction efficiency, a stirring shaft is now provided in the reactor to allow the raw materials to react fully. However, most stirring shafts are currently integrated with the reactor, making it inconvenient to replace or clean them. After a long time, residues of the raw materials will accumulate on the stirring shaft, affecting the reaction of subsequent raw materials. Utility Model Content

[0004] In order to solve the above problems, the utility model aims to provide a reactor heating device for oilfield chemical additive production.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: a reactor heating device for oilfield chemical additive production comprises a reactor body, an inner tank is arranged inside the reactor body, a heating chamber is formed between the reactor body and the inner tank, a plurality of heating tubes distributed in an annular manner are arranged in the heating chamber, a lower hopper is arranged at the bottom of the reactor body, the lower hopper passes through the bottom of the reactor body and is fixedly provided with a first gear, a rotating shaft is rotatably arranged on the lower surface of the outer wall of the reactor body, a second gear meshing with the first gear is fixedly arranged on the rotating shaft, the second gear is a half-face gear, a cover plate is arranged at the upper end of the reactor body, a vertically arranged stirring shaft is rotatably arranged at the middle end of the cover plate, a stirring piece is fixedly arranged on the outer wall of the stirring shaft, a vertically arranged first vertical rod is arranged near the rotating shaft on the outer wall side of the reactor body, a second vertical rod is movably inserted at the upper end of the first vertical rod, a first belt is arranged on a transmission sleeve between the bottom of the first vertical rod and the rotating shaft, and a second belt is arranged between the top of the second vertical rod and the stirring shaft.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Example: Figure 1-3As shown, the utility model provides a reactor heating device for oilfield chemical additive production, comprising a reactor body 1, an inner liner 11 is arranged inside the reactor body 1, a heating chamber 12 is formed between the reactor body 1 and the inner liner 11, a plurality of heating tubes 13 distributed in an annular manner are arranged in the heating chamber 12, a lower hopper 14 is arranged at the bottom of the reactor body 1, the lower hopper 14 passes through the bottom of the reactor body 1 and is fixed with a first gear 15, a rotating shaft 16 is rotatably arranged on the lower surface of the outer wall of the reactor body 1, a second gear 17 meshing with the first gear 15 is fixed on the rotating shaft 16, and the second gear 17 is a half-face gear. The half-face gear can drive the first gear 15 to rotate intermittently, thereby increasing the residence time of the inner pot 11 and improving the heating effect. A cover plate 2 is provided at the upper end of the kettle body 1, and a vertically arranged stirring shaft 21 is rotatably provided at the middle end of the cover plate 2. A stirring member 22 is fixedly provided on the outer wall of the stirring shaft 21. A vertically arranged first vertical rod 3 is provided on the outer wall side of the kettle body 1 near the rotating shaft 16. A second vertical rod 31 is movably inserted at the upper end of the first vertical rod 3. A first belt 34 is provided on a transmission sleeve between the bottom of the first vertical rod 3 and the rotating shaft 16, and a second belt 35 is provided between the top of the second vertical rod 31 and the stirring shaft 21.

[0017] A driving motor 24 is installed at the bottom of the stirring shaft 21, and the output end of the driving motor 24 is coaxially fixed on the stirring shaft 21. The driving motor 24 can provide power for the rotation of the stirring shaft 21 and the inner tank 11, and it is convenient for the staff to operate; a support frame 25 is fixedly installed near the driving motor 24 on the upper end of the cover plate 2, and the driving motor 24 is fixedly placed on the support frame 25. The support frame 25 can support the driving motor 24, reduce the shaking of the driving motor 24 so that it can work stably.

[0018] A rotating plate 18 is fixedly provided on the outer wall of the lower hopper 14 . The rotating plate 18 is rotatably arranged inside the kettle body 1 . The arrangement of the rotating plate 18 enables the inner container 11 to rotate stably inside the kettle body 1 .

[0019] Two symmetrically distributed electric push rods 4 are installed on the outer wall of the kettle body 1. The output ends of the electric push rods 4 are coaxially fixed on the cover plate 2. The arrangement of the electric push rods 4 can facilitate the staff to control the movement of the cover plate 2. When the reaction is completed, the electric push rods 4 can push the cover plate 2 upward, drive the stirring shaft 21 and the stirring element 22 to move out of the kettle body 1 to separate them, thereby facilitating the staff to directly clean the stirring element 22 and the internal components of the kettle body 1, thereby increasing the convenience of the staff's operation.

[0020] The outer wall of the second vertical rod 31 is fixed with a protruding limit strip 32, and the limit strip 32 can be movably inserted into the first vertical rod 3 together with the second vertical rod 31. The setting of the limit strip 32 can make the first vertical rod 3 rotate together with the second vertical rod 31, so that the stirring shaft 21 and the first gear 15 rotate synchronously, thereby increasing the linkage of the device; two symmetrically distributed baffles 33 are fixed on the upper end of the second vertical rod 31, and a fixing block 36 is fixed on the side wall of the cover plate 2. The fixing block 36 can pass through the second vertical rod 31 and be located between the two baffles 33. The setting of the baffle 33 and the fixing block 36 can make the second vertical rod 31 move up together when the cover plate 2 moves up, thereby avoiding the second belt 35 between the second vertical rod 31 and the stirring shaft 21 from being deviated and causing it to fail to operate normally.

[0021] A sealing cover 23 is provided on the lower surface of the cover plate 2, and the bottom of the sealing cover 23 can be fitted on the top of the inner container 11 to prevent the entry of external impurities during the reaction process and affect the use, and also to prevent the leakage of heat inside the inner container 11.

[0022] Working principle: when in use, the heating tube 13 is started to generate hot air to heat the raw materials in the inner tank 11, and the driving motor 24 is working to drive the stirring shaft 21 to rotate. At this time, the stirring member 22 fixed on the stirring shaft 21 will rotate together to stir the raw materials required for the reaction in the inner tank 11 to improve the reaction efficiency. When the stirring shaft 21 rotates, the second vertical rod 31 can be driven to rotate by the second belt 35. The limit strip 32 fixed on the outer wall of the second vertical rod 31 can make the second vertical rod 31 rotate together with the first vertical rod 3. At this time, the first vertical rod 3 drives the rotating shaft 16 to rotate through the first belt 34, and the second gear 17 fixed on the rotating shaft 16 will drive the first gear 15 to rotate. At this time, the first gear 15 will drive the lower hopper 14 and the inner tank 11 fixed thereto to rotate together, so that the raw materials in the inner tank 11 can be heated evenly, avoiding the low reaction efficiency caused by the failure of the raw materials in a certain place to reach the target stability;

[0023] At the same time, since the stirring shaft 21 and the inner pot 11 are linked by the first gear 15 and the second gear 17 that are meshed, the stirring shaft 21 and the inner pot 11 will move in opposite directions, so that the raw materials inside the inner pot 11 are in the opposite direction to the stirring shaft 21, making the stirring more chaotic, the mixing effect is better, and the reaction efficiency is further improved;

[0024] When the reaction is completed, the reacted raw materials can be discharged through the lower hopper 14. At this time, the electric push rod 4 can push the cover plate 2 to move upward, driving the stirring shaft 21 and the stirring element 22 to move out of the kettle body 1 to separate them, so that the staff can directly clean the stirring element 22 and the internal components of the kettle body 1, increasing the convenience of the staff's operation.

[0025] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
