Description
Technical Field
[0001] This utility model relates to the field of isoborneol acrylate production equipment, and in particular to an isoborneol acrylate preparation device. Background Technology
[0002] There are two main methods for synthesizing isobornyl acrylate. The first method primarily uses acrylic acid and olefins as raw materials, and organic acids, solid superacids, heteropolyacids, and cation exchange resins as catalysts. The process involves dissolution, catalytic reaction, and the addition of polymerization inhibitors to produce isobornyl acrylate. The advantages of this method are abundant raw materials, high product yield, and the ability to achieve continuous production. However, it also has disadvantages such as long reaction time and complex production process. When conducting the catalytic reaction in a reactor, a catalyst needs to be added inside the reactor, and the amount of catalyst added is difficult to adjust. Although some reactors currently use structures to fix the catalyst, thus facilitating catalyst dosage adjustment, these fixed catalyst structures are often not evenly distributed within the reactor, thus affecting the reaction efficiency.

[0027] Please see Figure 1 and Figure 2 This invention provides an apparatus for preparing isoborneol acrylate, including a reaction vessel 2 and a stirring mechanism disposed on the reaction vessel 2. The stirring mechanism includes a drive motor 11, a rotating shaft 12, and multiple stirring blades 13. Each stirring blade 13 includes a support frame 131 and multiple sub-supports 132 disposed on the support frame 131. The sub-supports 132 extend vertically along the height direction of the support frame 131 and are detachably connected to the support frame 131. Multiple catalyst mesh boxes 133 are vertically disposed on the sub-supports 132. Each catalyst mesh box 133 is detachably connected to the sub-support 132. Specifically, the sub-supports 132 can be removed from the top of the support frame 131, and the catalyst mesh boxes 133 within them can be further disassembled. The catalyst mesh boxes 133 are used to hold the catalyst. By placing the catalyst in multiple catalyst mesh boxes 133, the catalyst distribution in the reaction vessel 2 can be made more uniform. During operation, the stirring mechanism rotates, allowing the catalyst on the stirring blades 13 to fully contact the reaction substrate, promoting the reaction.
[0028] Please see Figure 3 In one embodiment, the support frame 131 includes a first outer frame 1311 and multiple bottom support rods 1312; the bottom support rods 1312 are fixed to the bottom of the first outer frame 1311 and are used to support the sub-support 132.

[0030] Please see Figure 4 In one embodiment, the sub-support 132 includes a second outer frame 1321 and a plurality of first rectangular supports 1322 disposed in the middle of the second outer frame 1321; the plurality of first rectangular supports 1322 are arranged equidistantly along the height direction of the second outer frame 1321; the first rectangular supports 1322 are used to place catalyst mesh boxes 133. In this embodiment, when it is necessary to reduce the amount of catalyst, a portion of the catalyst mesh boxes 133 located in the middle of the sub-support 132 can be selectively removed, so that the plurality of catalyst mesh boxes 133 are distributed at intervals, and the catalyst is not excessively concentrated at the top or bottom in the reactor 2, thereby helping to improve the reaction yield.
[0031] Please see Figure 4 In one embodiment, the sub-support 132 further includes a fixing assembly 3, through which multiple catalyst mesh boxes 133 are fixed to the sub-support 132. Specifically, in use, the catalyst mesh boxes 133 are first placed on the sub-support 132, then fixed using the fixing assembly 3, and then the sub-support 132 is placed into the support frame 131.
[0032] Please see Figure 4 In one embodiment, the fixing assembly 3 includes a plurality of first fixing members 31, second fixing members 32, and third fixing members 33; the catalyst mesh box 133 is inserted into the sub-support 132 from the front or rear side; the plurality of first fixing members are detachably connected to the top front or rear side of the sub-support 132 for fixing the catalyst mesh box 133 located at the top of the sub-support 132; the plurality of second fixing members 32 are detachably connected to the front or rear side of the first rectangular support 1322 for fixing the catalyst mesh box 133 above and below the first rectangular support 1322; the plurality of third fixing members are detachably connected to the bottom front or rear side of the sub-support 132 for fixing the catalyst mesh box 133 located at the bottom of the sub-support 132.

Specifically, the front and rear walls of the first groove 311 are provided with through holes. The first screw 312 passes through the two through holes to lock the first fixing member 31 onto the second rectangular support 1323, thereby preventing the first fixing member 31 and the catalyst mesh box 133 from falling off during the stirring process.

[0036] Specifically, after the catalyst mesh box 133 is placed on both adjacent first rectangular supports 1322, the second groove 321 of the second fixing member 32 can be aligned and inserted downwards into the first rectangular supports 1322 of the two adjacent catalyst mesh boxes 133. The depth of the second groove 321 is greater than the thickness of the first rectangular support 1322. After the second fixing member 32 is inserted into the first rectangular support 1322, the upper and lower parts of the multiple second fixing members 32 are respectively located on the front or rear side of the two adjacent catalyst mesh boxes 133, thereby clamping the bottom of the upper catalyst mesh box 133 and the top of the lower catalyst mesh box 133 respectively.
[0037] Please see Figure 4 and Figure 7 In one embodiment, a third rectangular support 1324 is provided at the bottom of the sub-support 132; a catalyst mesh box 133 is provided between the third rectangular support 1324 and the upper first rectangular support 1322; the distance between the third rectangular support 1324 and the upper first rectangular support 1322 is equal to the height of the catalyst mesh box 133; a third groove 331 is provided at the top of the third fixing member 33; at least two third fixing members 33 are respectively provided at the front or rear part of the third rectangular support; the front or rear part of the third rectangular support is engaged with the third groove 331; the upper parts of the plurality of third fixing members 33 are located at the front or rear side of the catalyst mesh box 133, clamping the bottom of the catalyst mesh box 133; the third fixing member 33 also includes a third screw 332, which passes through the front wall and the rear wall of the third groove 331, and is used to fix the third fixing member 33 to the third rectangular support.
[0038] Specifically, after the catalyst mesh box 133 is placed on the third rectangular support 1324, the third groove 331 of the third fixing member 33 can be inserted into the third rectangular support 1324 from the bottom upward. The depth of the third groove 331 is greater than the thickness of the third rectangular support 1324. After the third fixing member 33 is inserted into the third rectangular support 1324, the upper part of the catalyst mesh box 133 at the bottom front side of the multiple third fixing members 33 clamps the bottom of the upper catalyst mesh box 133.
[0039] Please see Figure 8 In one embodiment, a handle 1325 is provided on the top of the sub-support 132, which is used to facilitate the removal of the sub-support 132 from the outer frame.
