Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to an organic reaction kettle which is easy to maintain. Background Art

[0002] A reactor is a comprehensive reaction vessel. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. The existing reactor generally includes a reactor body, a reactor cover, a heating device and a stirring device. There is a reaction chamber inside the reactor body. The stirring device extends into the reaction chamber through the reactor cover to stir the material. The reactor may be damaged due to many reasons during operation, resulting in the forced suspension of production. At this time, maintenance personnel are required to repair the inside of the reactor equipment. However, the reactor is generally large in size, and multiple people are required to move the reactor cover by rope lifting and manual transportation, and then repair the inside of the reactor body. This method consumes a lot of manpower and there are certain safety hazards during the transportation process.

[0003] For example, a Chinese patent document discloses a chemical reactor that is easy to maintain (publication number: CN210994296U). Although this patent drives the lifting and lowering of the reactor cover by the sliding lifting of the platform, the reactor cover is away from the upper end of the reactor shell, reducing the labor consumption of manual handling. By driving the motor, the bevel gear is driven to rotate, and then the reactor cover is rotated, which makes it convenient for workers to move the reactor cover to a suitable position and avoids safety hazards during the handling process.

[0004] However, the motor on the reactor cover and the internal stirring mechanism are usually an integrated structure, which means that when the reactor cover rises, the stirring shaft needs to be completely separated from the reactor shell before it can rotate. Therefore, the installation space requirements for the reactor are relatively strict, and the practicality is low. In addition, since the stirring mechanism and the motor above the reactor are an integrated structure, when the stirring mechanism is damaged, the reactor cover and the motor need to be taken out and dismantled as a whole, which increases the difficulty of maintenance.

DETAILED DESCRIPTION

[0023] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0024] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0025] Reference Figure 1-5, an organic reactor that is easy to maintain, comprising a reactor shell 1, the inner wall of the reactor shell 1 is fixedly connected with symmetrically distributed fixing blocks 2, the upper surface of the fixing blocks 2 is provided with slots 3, and the inner wall of one side of the slots 3 is provided with a receiving groove 4, the inner walls of the two slots 3 are movably plugged with support blocks 5, the slots 3 play the role of limiting support for both ends of the support blocks 5, and the inner wall of the support blocks 5 is installed with a stirring rod 6 through a bearing;

[0026] The upper end of the stirring rod 6 is provided with a disassembly device, and the disassembly device includes a connecting block 7 , and the lower surface of the connecting block 7 is fixedly connected to the upper end of the stirring rod 6 .

[0027] A trapezoidal groove 71 is provided on the upper surface of the connecting block 7, and a symmetrically distributed sliding groove 72 is provided on the upper surface of the fixed block 2. The inner wall of the sliding groove 72 is slidably connected to a limit slider 73. The upper surfaces of the two limit sliders 73 are fixedly connected to a mounting plate 74. The cooperation between the sliding groove 72 and the limit slider 73 enables the mounting plate 74 to move stably. A threaded hole 75 is provided on the upper surface of the mounting plate 74. A screw 76 is threadedly connected to the inner wall of the threaded hole 75. One end of the screw 76 is fixedly connected to a driving handle 77. The driving handle 77 facilitates the screw 76 to rotate. The other end of the screw 76 is fixedly connected to a pressing block 78.

[0028] The lower surfaces of the two pressing blocks 78 are in contact with the upper surface of the support block 5, and the pressing blocks 78 play a role in further fixing the support block 5. The outer surface of the reactor shell 1 is fixedly sleeved with an annular mounting block 79, and the upper surface of the annular mounting block 79 is fixedly installed with hydraulic cylinders 710 distributed in an annular array. One end of the piston rod of the multiple hydraulic cylinders 710 is fixedly connected to an annular lifting block 711, and the inner wall of the annular lifting block 711 is fixedly sleeved with a reactor cover 712. The piston rod of the hydraulic cylinder 710 drives the reactor cover 712 to prop up and open through the annular lifting block 711. The lower end of the reactor cover 712 contacts the upper end of the reactor shell 1, and a servo motor 713 is fixedly installed on the upper surface of the reactor cover 712. The output shaft of the servo motor 713 is fixedly installed with a rotating shaft 714 through a coupling. One end of the rotating shaft 714 penetrates and extends to the interior of the reactor cover 712, and one end of the rotating shaft 714 is fixedly connected with a trapezoidal block 715. One end of the trapezoidal block 715 is movably plugged into the inner wall of the trapezoidal groove 71. The plug-in cooperation between the trapezoidal block 715 and the trapezoidal groove 71 plays a role in transmitting the rotational power of the rotating shaft 714.

[0029] By providing a convenient disassembly device, it is convenient to disassemble and connect the stirring rod 6, so that when the stirring mechanism is damaged, the stirring rod 6 can be removed specifically for repair, which not only reduces manual labor but also improves maintenance efficiency, thereby improving practicality.

[0030] Working principle: Step 1, when the stirring rod 6 is damaged, the piston rod of the hydraulic cylinder 710 is started to extend, and the reactor cover 712 is driven to rise and separate from the reactor shell 1 through the annular lifting block 711. The rise of the reactor cover 712 drives the trapezoidal block 715 to separate from the trapezoidal groove 71 through the servo motor 713 and the rotating shaft 714, and then the screw 76 is driven to rotate counterclockwise through the driving handle 77. The rotation of the screw 76 causes the pressing block 78 to separate from the fixation of the support block 5, and the mounting plate 74 is moved to move the pressing block 78 into the accommodating groove 4 through the cooperation of the slide groove 72 and the limit slider 73. After the pressing block 78 cancels the obstruction of the support block 5, the stirring rod 6 can be removed by taking the support block 5 out of the slot 3 for maintenance;

[0031] Step 2, when the maintenance is completed, the two ends of the support block 5 are inserted into the slot 3, and then the mounting plate 74 is moved through the cooperation of the slide groove 72 and the limit slider 73, so that it drives the pressure block 78 to move above the support block 5, and drives the screw rod 76 to rotate clockwise by driving the handle 77. The rotation of the screw rod 76 drives the pressure block 78 to further fix the support block 5, and finally starts the piston rod of the hydraulic cylinder 710 to retract, so that the reactor cover 712 moves downward to fit and seal with the upper end of the reactor shell 1. The downward movement of the reactor cover 712 causes the trapezoidal block 715 to be inserted into the trapezoidal groove 71, so that when the servo motor 713 drives the rotating shaft 714 to rotate, the rotating shaft 714 drives the connecting block 7 to rotate through the cooperation of the trapezoidal block 715 and the trapezoidal groove 71, and the rotation of the connecting block 7 drives the stirring rod 6 to rotate stably through the cooperation of the support block 5 and the bearing.
