Description

Technical Field

[0001] This utility model relates to the field of reaction device technology, and in particular to a reaction device for 3,3',4,4'-biphenyltetracarboxylic dianhydride. Background Technology

[0002] The reactor is used for the synthesis of 3,3',4,4'-biphenyltetracarboxylic dianhydride. Inside the reactor are mechanisms for temperature control, stirring, and other functions.

[0003] When using the reactor, the door is first opened, and then the material is put into the reactor through the feed inlet. Finally, the material reacts inside the reactor. However, the traditional door is hinged to the reactor. When feeding, the door may rotate in the opposite direction, causing the feed inlet to be re-blocked. Therefore, the door needs to be opened repeatedly when feeding, which increases the workload of the staff. Utility Model Content

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This invention, through the design of a fixed block, a positioning groove, a positioning block, and a driving component, allows the door to be opened by first rotating the door, which moves the fixed block to one side of the positioning block.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1-4 The apparatus shown is a reaction vessel for 3,3',4,4'-biphenyltetracarboxylic dianhydride, comprising a reaction vessel 1, with a door 2 hinged to the top of the reaction vessel 1, and further comprising:

[0023] Positioning component 3 is used to restrict the rotation of door 2. Positioning component 3 includes a fixing block 301 fixedly connected to one side of door 2. A positioning groove 302 is provided on one side of the fixing block 301. A positioning block 303 for fixing the position of fixing block 301 is inserted and connected inside the positioning groove 302.

[0024] Drive component 4 is located at the top of the reactor 1 and is used to move the positioning block 303.

[0025] The top of the reactor 1 is provided with a feed inlet 101 for feeding materials, and a handle 201 for driving the door 2 to rotate is fixedly connected to one side of the door body 2.

[0026] The horizontal longitudinal section of both the positioning groove 302 and the positioning block 303 is set as an isosceles trapezoid, and the driving component 4 is set on one side of the positioning block 303.

[0027] It should be noted that the reactor 1 and door 2 are electric heating reactors of model TJ-001. The feed inlet 101 is located at the top of the reactor 1, and the door 2 is located at the top of the feed inlet 101. The door 2 is hinged to the top of the reactor 1, allowing the door 2 to rotate at the top of the reactor 1, thereby closing and opening the feed inlet 101 by rotation. The handle 201 is fixed to one side of the door 2, allowing the handle 201 to drive the door 2 to rotate at the top of the reactor 1. The fixing block 301 is fixed to one side of the door 2, and the position of the door 2 is fixed by fixing the position of the fixing block 301 during use.

[0028] Specifically, the driving component 4 includes a connecting block 406 fixedly connected to one side of the positioning block 303, a driving block 404 fixedly connected to the back of the connecting block 406, a spring 402 provided on one side of the driving block 404, a pushing block 407 fixedly connected to the front of the connecting block 406, a pressing block 408 fixedly connected to the front of the pushing block 407 for driving the pushing block 407 to move, a fixed seat 401 fixedly connected to the top of the reactor 1, a through groove 405 opened on one side of the fixed seat 401, the connecting block 406 inserted into the inside of the through groove 405, a cavity 403 opened on the inner wall of one side of the through groove 405, and the spring 402 and the driving block 404 both inserted into the inside of the cavity 403.

[0029] It should be noted that the width of the driving block 404 is smaller than the width of the through slot 405, so that the driving block 404 cannot pass through the through slot 405 to exit the cavity 403. The cavity 403 is adapted to the driving block 404, so that the driving block 404 can slide inside the cavity 403. The spring 402 is set on one side of the driving block 404 and is used to push the driving block 404 towards the side of the connecting block 406. The width of the pushing block 407 is smaller than the width of the connecting block 406. When the connecting block 406 is pushed to the fixed block 301 and the position of the fixed block 301 is moved, space is reserved for the moving fixed block 301.

[0030] Furthermore, when it is necessary to restrict the position of the door 2, the restriction is achieved by pressing the block 408 to drive the push block 407, connecting block 406, and positioning block 303 to move towards one side of the fixed base 401. Then, the door 2 is rotated, and the fixed block 301 on one side of the door 2 is rotated until its bottom end is in contact with the top of the reactor 1. When the pressing of the block 408 is released, the spring 402 returns to its original deformation, and drives the drive block 404, connecting block 406, and positioning block 303 to move. This causes the positioning block 303 to move into the positioning groove 302. The positioning block 303, which cannot move towards the fixed block 301, restricts the position of the fixed block 301 and the door 2, preventing the door 2 from rotating and avoiding the situation where the door 2 rotates due to collision during use.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
