It is often used in the fields of petroleum, chemical industry, pharmaceuticals, etc. The reactor consists of a sealed container and a stirring system placed inside the container.

[0003] Conventional reactors adopt a fixed installation structure to ensure their stability during use. However, the reactor needs to be thoroughly cleaned when the reaction solution is replaced. Therefore, the reactor often needs to be opened for cleaning and maintenance. Since the reactor is large in size and fixed, cleaning and maintenance are extremely inconvenient. The prior art discloses a reactor that is easy to clean (patent announcement number CN211303034U). During cleaning and maintenance, the reactor can be tilted at a certain angle to facilitate operation by the staff. However, whether it is driven by a motor or a cylinder, additional driving force is required. Although the interaction of the connecting rods can tilt the reactor, it will take up a lot of space, thereby increasing the overall volume of the equipment. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0020] Please refer to Figure 1 - Figure 2As shown, a safety reactor for chemical production includes a support frame 1 and a reactor shell 4. The support frame 1 is fixed to the ground. An extension tube 2 is symmetrically arranged at the lower front side of the support frame 1. The extension tube 2 is in contact with the ground. The extension tube 2 and the support frame 1 are vertically arranged, and an oblique support is directly arranged between the two to ensure the stability of the support frame 1 as a whole and prevent it from tilting. A mounting frame 3 is symmetrically arranged at the lower front side of the support frame 1. The mounting frame 3 is triangular to improve the support strength. The reactor shell 4 is rotatably installed between the two mounting frames 3, and the reactor as a whole can be installed around it. The shaft is rotated, and a stirring shaft 5 is rotatably installed inside the reactor shell 4. The stirring shaft 5 is connected to the motor by a spline and a groove. A sandwich plate 6 is arranged at the lower outer side of the reactor shell 4, and a cavity for fluid to pass through is arranged between the sandwich plate 6 and the reactor shell 4, so as to inject flowing high-temperature or low-temperature liquid into the interior to achieve heating or cooling of the interior of the reactor. A feed pipe 7 is arranged on one side of the top of the reactor shell 4, and a liquid outlet pipe 8 is arranged at the bottom of the reactor shell 4. A control valve is installed inside the liquid outlet pipe 8 to facilitate the output of the chemical liquid.

[0021] Please refer to Figure 1 - Figure 3 As shown, an auxiliary arc plate 9 is symmetrically arranged on the upper front side of the support frame 1, and the auxiliary arc plate 9 is placed above the mounting frame 3. A movable arc bar 10 is slidably installed inside the auxiliary arc plate 9, and a fixing bolt 11 is arranged on the inner surface of the end of the movable arc bar 10. The fixing bolt 11 is placed on the outer side of the auxiliary arc plate 9, and the fixing bolt 11 is rotatably installed above the outer side of the reactor shell 4. The movable arc bar 10 is concentric with the rotation axis of the reactor shell 4. When the reactor shell 4 rotates around the mounting axis at its bottom, the movable arc bar 10 can be pulled out, and vice versa, the sliding of the movable arc bar 10 is controlled. The rotation angle of the reactor shell 4 can be controlled in the reverse direction. Arc grooves 91 are provided on both side surfaces of the auxiliary arc plate 9. The arc grooves 91 are concentric with the rotation axis of the reactor shell 4. Limit bolts 12 are provided on both side surfaces of the end of the movable arc strip 10 away from the fixed bolt 11. The two limit bolts 12 respectively penetrate the two arc grooves 91 so that the limit bolts 12 can only move inside the arc grooves 91. When the reactor shell 4 is in a vertical state, the limit bolts 12 are limited by the inner wall of the rear side of the arc groove 91 and are pulled by the pull rope 17 to ensure the stability of the reactor.

[0022] Please refer to Figure 3 and Figure 4As shown, a movable cavity 14 is provided inside the support frame 1, a threaded rod 15 is vertically installed inside the movable cavity 14 through a bearing, a lifting block 16 is screwed on the surface of the threaded rod 15, and the lifting block 16 can be controlled to move up and down by rotating the threaded rod 15. The slideway of the movable arc bar 10 is connected to the inside of the movable cavity 14, and a pull rope 17 is connected to the end of the movable arc bar 10 away from the fixing bolt 11, and the end of the pull rope 17 away from the movable arc bar 10 is connected to the surface of the lifting block 16. When the lifting block 16 moves down, the pull rope 17 can be pulled to drive the movable arc bar 10 to shrink inward, so that the reactor tends to a vertical state, otherwise the lifting block 16 moves up, the pull rope 17 is relaxed, and the reactor can tilt forward at this time.

[0023] Among them, a guide wheel 13 is rotatably installed on the inner wall of one side of the movable cavity 14 close to the movable arc bar 10. The guide wheel 13 is placed below the movable arc bar 10. The pull rope 17 runs through the surface of the guide wheel 13 to guide the pull rope 17 and improve its smoothness when moving.

[0024] Please refer to Figure 3 As shown, the threaded rod 15 passes through the upper surface of the support frame 1, and pulleys 18 are provided on the top of the two threaded rods 15. Belts 19 are sleeved on the surfaces of the two pulleys 18 to ensure the synchronous rotation of the two threaded rods 15, thereby ensuring the stability of the reaction kettle during rotation. A control handwheel 20 is provided on the top of one of the pulleys 18 for easy operation and control.

[0025] The working principle of the utility model is as follows: first, a motor is fixed on the top of the reactor shell 4 to drive the stirring shaft 5 to rotate, then the feed pipe 7 is connected to the chemical liquid, and the chemical liquid is poured into the reactor shell 4, stirred by the stirring shaft 5, and the temperature liquid is poured into the interlayer between the reactor shell 4 and the interlayer plate 6 to achieve heating or cooling. When cleaning or repairing, the control hand wheel 20 on the top can be rotated to drive one of the threaded rods 15 to rotate, and then the two threaded rods 15 are synchronously rotated in the same direction through the cooperation of the pulley 18 and the belt 19 to simultaneously control the movement of the two lifting blocks 16. When the lifting blocks 16 are on When the reactor shell 4 is moved, the pull rope 17 is loosened, and the reactor shell 4 can be pushed to rotate slowly around the installation axis at the bottom, so that the top of the reactor shell 4 is tilted forward, which is convenient for inspection and debugging. Conversely, the control hand wheel 20 is rotated, and the lifting block 16 moves down to pull the pull rope 17 down, and then the movable arc bar 10 is pulled inward by the pull rope 17, so that the reactor shell 4 is in a vertical state. Due to the cooperation of the limit bolt 12 and the arc groove 91, the rotation angle of the reactor shell 4 is effective. When the reactor shell 4 is in a vertical state, the limit bolt 12 is limited by the end of the arc groove 91. At this time, the control hand wheel 20 cannot continue to rotate to keep the reactor shell 4 stable.

[0026] The above are only preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the art unless otherwise specified or limited.
