Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and more specifically, to a reaction vessel for industrial production. Background Technology

[0002] Industrial production reactors are core equipment used in industries such as chemical, pharmaceutical, new materials, food, and environmental protection for carrying out chemical reactions. They provide a closed and controllable environment, allowing raw materials to undergo physical or chemical changes under specific temperature, pressure, stirring, and atmospheric conditions, thereby synthesizing the target product.

[0003] The stirring racks in the reaction vessels used in chemical industrial production are relatively simple and cannot fully mix various reaction reagents, resulting in prolonged reaction time. In addition, the solidified solids can block the discharge port, making it difficult to discharge the material. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a reaction vessel for industrial production, which solves the technical problem mentioned in the background art that the stirring rack in the reaction vessel used in chemical industrial production is relatively simple and cannot fully mix various reaction reagents, resulting in a prolonged reaction time.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An industrial production reactor includes a reactor, a feeding assembly at the top of the reactor, four sets of support legs at the outer end of the reactor, a bottom cover at the bottom of the reactor, a discharge pipe at the bottom of the bottom cover, a discharge valve on the discharge pipe, a motor at the top of the reactor, a rotating shaft passing through the top of the reactor at the output end of the motor, multiple sets of paddle-type stirring blades at the upper part of the rotating shaft, and multiple sets of anchor-type stirring blades at the lower part of the rotating shaft.

[0009] The present invention is further configured such that a support plate is provided at the bottom of the bottom cover, and a spiral conveying roller is rotatably provided at the top of the support plate. The top of the spiral conveying roller is connected to the bottom of the rotating shaft. When it is necessary to discharge the reagent, the rotating shaft rotates, which drives the spiral conveying roller to rotate and opens the discharge valve. The reagent in the reaction vessel is then discharged through the discharge pipe under the action of the spiral conveying roller, realizing "discharging while stirring". This provides good continuity and effectively avoids reagent clogging of the discharge pipe.

[0010] The present invention is further configured such that a filter screen is provided in the lower part of the reactor, and a perforation is provided in the middle of the filter screen. The rotating shaft is rotatably connected to the perforation. When discharging, the reagent is filtered through the filter screen and discharged through the bottom cover and the discharge pipe. This can intercept large particles, catalyst residues or impurities before discharge, ensuring that the discharged liquid is clean and protecting the pump valve and downstream equipment.

[0011] The present invention is further configured such that the bottom cover is rotatably mounted on the bottom end of the reactor, a handle is provided on the left end of the bottom cover, a retaining seat is provided on the upper side of the left end of the bottom cover, and a latch lock body is provided on the lower side of the left end of the reactor. The latch lock body cooperates with the retaining seat to lock in place. When the filter screen needs to be cleaned, the latch lock body is separated from the retaining seat, and then the bottom cover is opened through the handle, exposing the filter screen for manual cleaning, which facilitates the exposure of the filter screen for cleaning.

[0012] The present invention is further configured such that fixing plates are provided on the front, rear, left, and right sides of the lower part of the reactor, and screws are provided at the bottom of the four fixing plates. The filter screen is provided with through holes at the front, rear, left, and right sides, and the four through holes correspond to the positions of the four screws. After the four screws pass through the four through holes of the filter screen, nuts are threaded onto them. When the bottom cover is opened and the filter screen needs to be disassembled, the filter screen can be removed from the four screws for cleaning by unscrewing the four nuts, which facilitates the removal of the filter screen from the reactor for cleaning.

[0013] The present invention is further configured such that a square locking block is provided at the top of the spiral conveying roller, and a square groove is provided at the bottom of the rotating shaft. The square locking block and the square groove are engaged and locked together. When the bottom cover is opened, the square locking block at the top of the spiral conveying roller separates from the square groove at the bottom of the rotating shaft, and the spiral conveying roller moves with the bottom cover. When the bottom cover is installed on the bottom of the reactor, the square locking block engages with the square groove at the bottom of the rotating shaft, thereby connecting the rotating shaft and the spiral conveying roller, which facilitates the connection and separation of the rotating shaft and the spiral conveying roller.

[0014] The present invention is further provided with a sealing ring at the top of the bottom cover. By providing the sealing ring, the sealing performance between the reactor and the bottom cover can be improved.

[0015] Beneficial effects

[0017] 1. The reactor is equipped with a bottom cover, a discharge valve on the discharge pipe, and a motor at the top. A rotating shaft passes through the top of the reactor from the motor's output end. Multiple sets of paddle-type stirring blades are installed on the upper part of the rotating shaft, and multiple sets of anchor-type stirring blades are installed on the lower part of the rotating shaft. Various reagents are introduced into the reactor through the feeding assembly. When the motor is turned on, it drives the rotating shaft to rotate. The multiple sets of paddle-type stirring blades and anchor-type stirring blades on the rotating shaft stir the various reagents in the reactor to ensure uniform mixing. The multiple sets of paddle-type stirring blades can provide strong axial / radial flow, promote overall liquid circulation, and accelerate dissolution and mass transfer. The multiple sets of anchor-type stirring blades run close to the inner wall of the reactor, scraping off the wall deposits and preventing solids from accumulating at the bottom and side walls, achieving a dual effect of "macro-circulation + micro-wall scraping".

[0018] 2. A support plate is provided at the bottom of the bottom cover, and a spiral conveying roller is rotatably installed at the top of the support plate. The top of the spiral conveying roller is connected to the bottom of the rotating shaft. When it is necessary to discharge the reagent, the rotating shaft rotates, which drives the spiral conveying roller to rotate and opens the discharge valve. The reagent in the reactor is then discharged through the discharge pipe under the action of the spiral conveying roller, realizing "discharging while stirring". It has good continuity and effectively avoids reagent clogging of the discharge pipe.

[0019] 3. A filter screen is installed in the lower part of the reactor, and a perforation is provided in the middle of the filter screen. The rotating shaft is rotatably connected to the perforation. When discharging, the reagent is filtered through the filter screen and discharged through the bottom cover and the discharge pipe. Large particles, catalyst residues or impurities can be intercepted before discharge to ensure that the discharged liquid is clean and to protect the pump valve and downstream equipment.

[0030] In this embodiment, multiple reagents are introduced into the reactor 1 through the feeding assembly 2. By turning on the motor 7, the motor 7 drives the rotating shaft 8 to rotate. Multiple sets of paddle-type stirring blades 9 and multiple sets of anchor-type stirring blades 10 on the rotating shaft 8 stir the multiple reagents in the reactor 1 to make them mix evenly. The multiple sets of paddle-type stirring blades 9 can provide strong axial / radial flow, promote the overall circulation of liquid, and accelerate dissolution and mass transfer. The multiple sets of anchor-type stirring blades 10 run close to the inner wall of the reactor 1, scraping off the wall deposits and preventing solids from accumulating at the bottom and side walls, achieving the dual effect of "macro circulation + micro wall scraping".

[0031] Please see Figure 2 and Figure 5As one embodiment of the bottom cover 4, the bottom of the bottom cover 4 in this utility model is provided with a support plate 11, and a spiral conveying roller 12 is rotatably provided at the top of the support plate 11. The top of the spiral conveying roller 12 is connected to the bottom of the rotating shaft 8.

[0032] Specifically, when it is necessary to discharge the reagent, the rotating shaft 8 rotates, which drives the spiral conveying roller 12 to rotate, opening the discharge valve 6. The reagent in the reactor 1 is then discharged through the discharge pipe 5 under the action of the spiral conveying roller 12, realizing "discharging while stirring", which has good continuity and effectively avoids the reagent clogging the discharge pipe 5.

This can intercept large particles, catalyst residues, or impurities before discharge, ensuring the cleanliness of the discharged liquid and protecting the pump valves and downstream equipment. When the filter screen 13 needs to be cleaned, the latch lock body 16 is separated from the seat 15, and then the bottom cover 4 is opened through the handle 14, exposing the filter screen 13 for manual cleaning. This facilitates the exposure of the filter screen 13 for cleaning. When the bottom cover 4 is opened and the filter screen 13 needs to be disassembled, the four sets of nuts 19 are unscrewed to remove the filter screen 13 from the four sets of screws 18 for cleaning, making it easy to remove the filter screen 13 from the reactor 1 for cleaning.
