[0002] Hydroxy ester alkyl acid reaction apparatus is a specialized device used for chemical reactions such as the synthesis, modification, or degradation of hydroxy ester alkyl acids. Existing hydroxy ester alkyl acid reaction apparatuses are typically equipped with a stirring mechanism, which ensures sufficient contact between the input materials, avoids excessively high or low local concentrations, and reduces side reactions.
[0003] However, existing hydroxy ester alkyl acid reaction devices can only perform simple horizontal stirring of materials during use, and cannot stir materials vertically. This results in low material mixing and reaction efficiency, and after use, some material that is difficult to discharge will adhere to the inner wall, thus causing material waste.
[0004] Therefore, it is necessary to provide a hydroxy ester alkyl acid reaction apparatus to solve the above-mentioned technical problems. Utility Model Content

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0017] Please refer to the following: Figure 1-3 ,in, Figure 1 A schematic diagram of a preferred embodiment of the hydroxy ester alkyl acid reaction apparatus provided by this utility model; Figure 2 for Figure 1 An enlarged schematic diagram of part A is shown below; Figure 3 for Figure 1 The enlarged schematic diagram of part B is shown. The hydroxy ester alkyl acid reaction apparatus includes: a vessel body 1, a hollow shaft 2 rotatably mounted on the vessel body 1, a motor 3 fixedly mounted on the top of the vessel body 1, and the output shaft of the motor 3 fixedly connected to the top end of the hollow shaft 2; a support rod 4 rotatably mounted on the hollow shaft 2, the bottom end of the support rod 4 fixedly connected to the bottom inner wall of the vessel body 1; multiple first bevel gears 5 fixedly sleeved on the support rod 4; multiple material stirring mechanisms assembled on the hollow shaft 2 for reacting hydroxy ester alkyl acids; and two scraping mechanisms installed on the hollow shaft 2 for cleaning the inner wall of the vessel body 1.
[0018] The material stirring mechanism includes: a rotating shaft 6 rotatably mounted on the hollow shaft 2, a second bevel gear 7 fixedly mounted at one end of the rotating shaft 6, the second bevel gear 7 meshing with the first bevel gear 5; and stirring blades 8 welded to the rotating shaft 6.
[0019] The scraping mechanism includes: a plurality of sleeves 9 fixedly installed on the hollow shaft 2, and springs 10 fixedly installed on the inner walls of the plurality of sleeves 9; a plurality of sliding rods 11 respectively slidably installed on the plurality of sleeves 9, and one end of the plurality of sliding rods 11 is fixedly connected to the plurality of springs 10; and scrapers 12 fixedly installed on the plurality of sliding rods 11, the scrapers 12 being in contact with the inner wall of the vessel body 1.
[0020] The hydroxy ester alkyl acid reaction apparatus also includes a maintenance mechanism installed on the vessel body 1, which is used to inspect the interior of the vessel body 1.
[0021] The maintenance mechanism includes: an inspection port opened on the vessel body 1; a sealing door 13 hinged to the vessel body 1, the sealing door 13 being adapted to the inspection port, and a first triangular block 14 fixedly installed on the sealing door 13; an electric push rod 15 fixedly installed on the outer wall of the vessel body 1, and a second triangular block 16 fixedly installed on the output rod of the electric push rod 15, the second triangular block 16 being in contact with the first triangular block 14.
[0022] A feeding pipe 17 is fixedly installed on the top of the vessel body 1, and a sealing cap is threaded onto the feeding pipe 17.
[0023] A through pipe is fixedly installed on the top of the vessel body 1, and a safety valve 18 is fixedly installed on the through pipe. A discharge pipe 19 is fixedly installed on the bottom of the vessel body 1, and a valve is provided on the discharge pipe 19.
[0024] The working principle of the hydroxy ester alkyl acid reaction device provided by this utility model is as follows: During use, unscrew the sealing cap on the feeding pipe 17 and feed the materials required for the hydroxy ester alkyl acid reaction into the reactor body 1 through the feeding pipe 17. After feeding, tighten the sealing cap to seal the feeding pipe 17. At this time, the valve on the discharge pipe 19 remains closed. Then, start the motor 3. The output shaft of the motor 3 drives the hollow shaft 2 to rotate. When the hollow shaft 2 rotates, it simultaneously drives multiple material stirring mechanisms to rotate laterally, stirring the materials in the reactor body 1 laterally. During the lateral stirring process, the second bevel gear 7 on the material stirring mechanism will roll on the first bevel gear 5 on the support rod 4. The second bevel gear 7 will drive the rotating shaft 6 to rotate on the hollow shaft 2. The rotating shaft 6 will drive the stirring blade 8 to rotate, so that the stirring blade 8 can rotate laterally and longitudinally at the same time, realizing the lateral and longitudinal compound stirring of the materials in the reactor body 1, ensuring that the materials are fully contacted and reacted, which can effectively improve the mixing reaction efficiency between materials. If the pressure in the reactor body 1 rises abnormally during the reaction process, the safety valve 18 will automatically release pressure through the pipe to ensure the safe operation of the device. After the reaction is complete, the valve on the discharge pipe 19 can be opened to discharge the reacted hydroxy ester alkyl acid. During the discharge process, the motor 3 also needs to be started so that the hollow shaft 2 can drive multiple sleeves 9 to rotate. The spring 10 inside the sleeve 9 pushes the slide rod 11 through elastic force, so that the scraper 12 fixed on the slide rod 11 is always in close contact with the inner wall of the vessel body 1. Under the rotation of the sleeve 9, the slide rod 11 will also drive the scraper 12 to rotate at the same time, thereby scraping off the material attached to the inner wall of the vessel body 1, which can effectively avoid material residue and waste. When it is necessary to inspect the inside of the vessel body 1, the electric push rod 15 is activated. The output rod of the electric push rod 15 drives the second triangular block 16 to disengage from the first triangular block 14. After disengagement, the sealing door 13 hinged to the vessel body 1 can be opened, allowing the sealing door 13 to disengage from the inspection port. Then, the inside of the vessel body 1 can be inspected and maintained through the inspection port. After the inspection is completed, the sealing door 13 is closed, and the electric push rod 15 is activated to push the second triangular block 16 to make close contact with the first triangular block 14 again, so as to achieve the sealing and fixation of the sealing door 13. The operation is relatively simple.
[0025] Compared with related technologies, the hydroxy ester alkyl acid reaction apparatus provided by this utility model has the following beneficial effects: This invention provides a hydroxy ester alkyl acid reaction device. Using a motor 3, the hollow shaft 2 drives multiple material stirring mechanisms to rotate laterally, stirring the materials inside the vessel 1. Through the cooperation of a support rod 4 and multiple first bevel gears 5, the stirring blades 8 in the multiple material stirring mechanisms can rotate longitudinally while rotating laterally, achieving combined lateral and longitudinal stirring of the materials inside the vessel 1. This ensures sufficient contact and reaction of the materials, effectively improving the mixing efficiency. The use of two scraping mechanisms allows for the discharge of the reacted hydroxy ester alkyl acid while scraping off the material adhering to the inner wall of the vessel 1, effectively preventing material residue inside the vessel 1 and reducing material waste. The device exhibits good performance.
