Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel technology, and in particular to a reaction vessel for dimethoxyaniline that facilitates the filtration of raw materials. Background Technology
[0002] Dimethoxyaniline is an organic compound that is a colorless to pale yellow liquid with a distinctive aromatic odor. The production of dimethoxyaniline requires the use of a reaction vessel. In a broad sense, a reaction vessel is a container in which physical or chemical reactions occur. Through the structural design and parameter configuration of the vessel, the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process can be achieved.
[0003] In existing technologies, most reactors directly add raw materials from the feed pipe, and after the stirring system mixes them evenly, the reaction is carried out under conditions such as heating. However, they do not have a filtration mechanism, which means that when using the reactor to prepare products, impurities in the raw materials (such as some solid chemical particles) will also participate in the reaction. On the one hand, this will generate other products, waste raw materials, and reduce the production rate of the planned products. On the other hand, it will cause impurities to be mixed in with the products after the reaction, affecting the product quality. Utility Model Content

[0029] Reference Figures 1 to 5 This utility model provides a reaction vessel for dimethoxyaniline that facilitates the filtration of raw materials: it includes a vessel body 1 and a cover body 2. The cover body 2 is located at the top of the vessel body 1. A drive motor 3 is fixedly installed on the upper surface of the cover body 2.

[0032] By configuring a reactor body 1, a cover 2, a drive motor 3, a rotating rod 4, a stirring component 5, a filter box 6, a filter screen 7, a feed pipe 8, a discharge pipe 9, a groove 10, a frame 11, a slider 12, a positioning rod 13, a pressure plate 14, a nut 15, a limiting plate 16, a fixing block 17, a reciprocating screw 18, a throttle 19, a sliding rod 20, and a brush block 21, the function of filtering raw materials before adding them to the reactor is realized.

[0033] The vessel body 1 is equipped with a fixing component, which includes a connecting ring 22 and a connecting groove 23. The connecting ring 22 is fixedly installed on the lower surface of the cover body 2. The connecting groove 23 is opened on the inner wall of the top of the vessel body 1. The connecting ring 22 is located inside the connecting groove 23. A sealing sleeve 24 is slidably connected to the inner wall of the connecting groove 23. A positioning block 25 is fixedly installed on the outer surface of the sealing sleeve 24.

Two positioning plates 26 are fixedly installed on the outer surface of the cover body 2. Two positioning frames 27 are fixedly installed on the outer surface of the vessel body 1. The outer surfaces of the two positioning frames 27 are threaded with fixing bolts 28. The two positioning plates 26 are respectively inserted into the two positioning frames 27. The fixing bolts 28 penetrate the outer surface of the positioning frames 27 and are inserted into the positioning plates 26.
[0034] By setting up a connecting ring 22, a connecting groove 23, a sealing sleeve 24, a positioning block 25, a positioning plate 26, a positioning frame 27, and a fixing bolt 28, the function of quickly and conveniently opening and closing the reactor is realized. This improves the connection method between the reactor body 1 and the cover 2 in the prior art, making it faster and more convenient to connect the cover 2 to the reactor body 1, saving time and effort, and enhancing the practicality of the reactor.
[0035] Working principle: When using the reactor to produce products, the raw materials are introduced into the feed pipe 8, allowing them to enter the filter box 6. After passing through the filter screen 7, the filter screen 7 filters out impurities in the raw materials. The filtered raw materials continue downwards into the reactor body 1, where the reactor can then be used to produce products. During this process, the drive motor 3 is turned on. When the drive motor 3 is running, it drives the rotating rod 4 to rotate inside the reactor body 1, thereby causing the stirring element 5 to rotate inside the reactor body 1, thus accelerating the reaction. After the product is produced, the valve on the discharge pipe 9 is opened to allow the discharge pipe 9 to flow freely, and the product is discharged from the reactor body 1 through the discharge pipe 9.
[0036] When the filter screen 7 is clogged and needs to be cleaned, turn the handle 19. When the handle 19 turns, it drives the reciprocating screw 18 to rotate inside the filter box 6, thereby driving the brush block 21 to move. Under the action of the slide rod 20, the brush block 21 moves back and forth along the outer surface of the slide rod 20 and the outer surface of the reciprocating screw 18. During this process, the bristles on the brush block 21 brush and clean the filter screen 7.
[0037] When the filter screen 7 needs to be replaced, rotate the limiting plate 16 upwards so that the limiting plate 16 rotates out of the inside of the fixing block 17, releasing the restriction on the frame 11. Then pull the frame 11 so that the frame 11 slides out of the inside of the filter box 6 through the groove 10. The slider 12 slides inside the slide groove. After the frame 11 slides out of the inside of the filter box 6, turn the nut 15 so that the nut 15 disengages from the positioning rod 13, releasing the pressure on the pressure plate 14. At this time, the pressure plate 14 and the filter screen 7 can be removed from the positioning rod 13. Then, take the removed filter screen 7 and reverse the above operation to install the new filter screen 7 into the filter box 6, completing the replacement of the filter screen 7. During the replacement of the filter screen 7, the raw material impurities accumulated inside the frame 11 can also be removed.
[0038] When it is necessary to separate the reactor body 1 and the cover 2, tighten the two fixing bolts 28 so that the fixing bolts 28 extend away from the positioning frame 27. After the fixing bolts 28 separate from the positioning plate 26, the restriction on the positioning plate 26 is released, thereby releasing the fixation on the cover 2. At this time, lift the cover 2 upward so that the connecting ring 22 moves upward inside the connecting groove 23 and the positioning plate 26 moves upward inside the positioning frame 27. During the lifting of the cover 2, the stirring component 5 is also removed from the inside of the reactor body 1 by the drive motor 3. After the cover 2 is separated from the reactor body 1, the sealing sleeve 24 is removed from the connecting groove 23. At this time, the inside of the reactor body 1 can be cleaned or repaired. After the cleaning or repair is completed, the above operation is reversed to reinstall the cover 2 onto the reactor body 1.
[0039] 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.
