DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Example

[0023] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0024] A mixing kettle for producing methyl methacrylate, comprising a mixing kettle body 1, support platforms 2 are arranged on both sides of the mixing kettle body 1, bases 3 are arranged at the bottoms of the two sets of support platforms 2, connecting components 4 are arranged on the inner sides of the two sets of support platforms 2 and at positions corresponding to the mixing kettle body 1, and a driving component 5 is arranged on the top of the base 3 and at a position corresponding to the connecting component 4;

[0025] A stirring motor 101 is disposed on the top of the mixing kettle body 1 , a stirring rod 102 is disposed inside the mixing kettle body 1 at a position corresponding to the stirring motor 101 , and a stirring blade 103 is fixedly connected to the outer side of the stirring rod 102 .

[0026] A support frame 301 is slidably connected to the top of the base 3 and located below one of the groups of support platforms 2. A support plate 302 is fixedly connected to the front of the support frame 301 and located below the driving assembly 5. A push handle 303 is fixedly connected to the top of the base 3. The outer side of the push handle 303 is provided with a plurality of anti-slip rings 304 made of rubber. Universal wheels are installed on all four sides of the bottom of the base 3.

[0027] Specifically, first, the base 3 is pushed by the push handle 303, and the anti-slip ring 304 increases the friction force on the surface of the push handle 303. After the base 3 is moved to the specified position, the support plate 302 supports the drive component 5, and the support frame 301 and the base 3 respectively support the two groups of support platforms 2. The support platform 2 is connected to the mixing kettle body 1 through the connecting component 4. When in use, the driving component 5 drives the mixing kettle body 1 to rotate between the two groups of support platforms 2. At the same time, the stirring motor 101 drives the stirring rod 102 to rotate in the mixing kettle body 1, and drives the stirring blade 103 to rotate through the stirring rod 102, and then the methyl methacrylate in the mixing kettle body 1 is stirred and mixed by the stirring blade 103, thereby improving the mixing efficiency and mixing effect.

[0028] Also, see Figure 1 and Figure 3 A connecting assembly 4 is disposed on the inner side of the two sets of support platforms 2 and at a position corresponding to the mixing kettle body 1, and a driving assembly 5 is disposed on the top of the base 3 and at a position corresponding to the connecting assembly 4;

[0029] The connecting assembly 4 is used to limit the installation of the mixing kettle, and the driving assembly 5 is used to drive the mixing kettle to rotate. The specific structures of the connecting assembly 4 and the driving assembly 5 are as follows:

[0030] The connecting assembly 4 includes two groups of connecting grooves 401, a hydraulic cylinder 402, a clamping plate 403 and a rolling wheel 404. The two groups of connecting grooves 401 are respectively opened inside the two groups of support platforms 2 and are located at positions corresponding to the mixing kettle body 1. Hydraulic cylinders 402 are installed on the outsides of the two groups of support platforms 2 and at positions corresponding to the connecting grooves 401. Clamping plates 403 are slidably connected inside the support platforms 2 and at positions corresponding to the hydraulic cylinders 402. Three groups of rolling wheels 404 are arranged inside the four groups of clamping plates 403. Roller grooves are opened on the inner sides of the four groups of clamping plates 403 and at positions corresponding to several rolling wheels 404.

[0031] The driving assembly 5 includes a mounting seat 501, a supporting seat 502, a driving motor 503 and a coupling 504. The mounting seat 501 is arranged on the top of the base 3, the supporting seat 502 and the driving motor 503 are arranged on the top of the mounting seat 501, and the coupling 504 is arranged on the top of the supporting seat 502.

[0032] Specifically, the support platform 2 is driven to move by the sliding support frame 301, and then the distance between the two groups of support platforms 2 is adjusted, and the mixing kettle body 1 is placed between the two groups of support platforms 2. The left and right sides of the mixing kettle body 1 and the corresponding positions of the two groups of connecting components 4 are fixedly connected with rotating shafts, and the rotating shafts on the left and right sides of the mixing kettle body 1 are limited by the connecting component 4, and the clamping plate 403 is driven to move in the connecting groove 401 by the hydraulic cylinder 402, and then the mixing kettle body is clamped by the clamping plate 403. The rotating shafts on the left and right sides of the body 1 are limited. At this time, the rolling wheels 404 reduce the friction between the rotating shaft and the clamping plate 403, so that the mixing kettle body 1 can rotate between the two groups of support platforms 2. When the rotating shaft is engaged with the coupling 504, the mounting seat 501 supports the driving motor 503, and the supporting seat 502 supports the coupling 504, so that the coupling 504 is driven to rotate through the driving motor 503, and the mixing kettle body 1 is driven to rotate between the two groups of support platforms 2 through the rotating shaft.

[0033] In this embodiment, the implementation scenario is specifically as follows: in actual use, the base 3 is first pushed by the push handle 303, and the anti-slip ring 304 increases the friction force on the surface of the push handle 303. After the base 3 is moved to the specified position, the support plate 302 supports the drive component 5, and the support frame 301 and the base 3 respectively support the two groups of support platforms 2. The support platform 2 is connected to the mixing kettle body 1 through the connecting component 4. When in use, the driving component 5 drives the mixing kettle body 1 to rotate between the two groups of support platforms 2. At the same time, the stirring motor 101 drives the stirring rod 102 to rotate in the mixing kettle body 1, and drives the stirring blade 103 to rotate through the stirring rod 102, and then the methyl methacrylate in the mixing kettle body 1 is stirred and mixed by the stirring blade 103, thereby improving the mixing efficiency and mixing effect. Compared with the existing mixing kettle for methyl methacrylate production, the utility model can improve the overall practicality of the mixing kettle for methyl methacrylate production through design.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
