The sliding drive assembly is drivingly connected to the reactor body 11 to drive the reactor body 11 to slide in the horizontal direction. The lifting drive assembly is drivingly connected to the reactor cover 12 to drive the reactor cover 12 to rise and fall vertically.

[0035] The stirring head 133 includes a shaft sleeve 1331 and a plurality of stirring blades 1332 welded and fixed to the outer periphery of the shaft sleeve 1331 . The shaft sleeve 1331 is sleeved on the rear end of the stirring shaft 131 , and the outer periphery of the shaft sleeve 1331 is connected to the stirring shaft 131 via a plurality of fastening bolts.

[0036] Reference Figure 1 and Figure 3 When switching the stirring head 133 of the stirrer 13 with different blade shapes, the lifting drive assembly first drives the kettle cover 12 to drive the stirrer 13 to move upward and away from the kettle body 11, and then the sliding drive assembly drives the kettle body 11 to slide in the horizontal direction until the kettle body 11 and the kettle cover 12 are staggered in the horizontal direction, and then the lifting drive assembly drives the kettle cover 12 to drive the stirrer 13 to move downward, so that the operator can disassemble and replace the stirring head 133 at the tail end of the stirring shaft 131.

[0037] The sliding drive assembly includes a horizontally arranged electric screw module 2, which includes a slide 21. The outer periphery of the kettle body 11 is connected to the slide 21 through a plurality of legs 111, so that the sliding drive assembly is driven and connected to the kettle body 11. The lifting drive assembly includes two vertically arranged lifting cylinders 3, which are respectively located on opposite sides of the electric screw module 2, and the top ends of the piston rods of the two lifting cylinders 3 are connected to the outer periphery of the kettle cover 12 through a connecting block, so that the lifting drive assembly is driven and connected to the kettle cover 12.

[0038] Reference Figure 4 and Figure 5, an auxiliary disassembly and assembly mechanism 4 is also supported on the slide 21, and the auxiliary disassembly and assembly mechanism 4 and the kettle body 11 are respectively located at the two ends of the slide 21 of the electric screw module 2. The auxiliary disassembly and assembly mechanism 4 includes a support ring 41 and a first lifting drive member; the inner circumference contour of the support ring 41 matches the outer circumference contour of the stirring shaft 131, so that the support ring 41 allows the rear end of the stirring shaft 131 to penetrate, and a bracket 410 is connected to the bottom of the support ring 41. The first lifting drive member includes a first lifting cylinder 42 vertically supported on the slide 21, the first lifting cylinder 42 is located at the bottom of the support ring 41, and the piston rod of the first lifting cylinder 42 is connected to the bracket 410, so as to realize the driving connection between the first lifting drive member and the support ring 41, and the support ring 41 can be driven to rise and fall vertically by the first lifting cylinder 42 later.

[0039] Reference Figure 5 and Figure 6 A clamping assembly is also provided on the support ring 41, and the clamping assembly includes a plurality of clamping parts 43, and the plurality of clamping parts 43 are evenly distributed around the axial direction of the support ring 41. The clamping part 43 includes a clamping block 431 and a first sliding drive member. The clamping block 431 is protrudingly provided on the upper surface of the support ring 41, and the first sliding drive member is drivingly connected to the clamping block 431, and is used for driving the clamping block 431 to move toward or away from the axial direction of the support ring 41.

[0040] Specifically, the first sliding drive component includes a first sliding cylinder 432, and the support ring 41 is provided with a plurality of mounting grooves 411 corresponding to the first sliding cylinder 432. The first sliding cylinders 432 are all embedded and installed in the corresponding mounting grooves 411. The first sliding cylinders 432 are all axially arranged toward the support ring 41, and the piston rods of the first sliding cylinders 432 are all connected to the corresponding clamping blocks 431.

[0041] Through the setting of the auxiliary disassembly and assembly mechanism 4, the electric screw module 2 drives the slide 21 to drive the kettle body 11 to stagger the kettle cover 12, so that the auxiliary disassembly and assembly mechanism 4 is located below the agitator 13 of the kettle cover 12; when disassembling and replacing the stirring head 133 located on the stirring shaft 131, the first lifting cylinder 42 drives the support ring 41 to move up until the support ring 41 abuts against the bottom of the shaft sleeve 1331 of the stirring head 133 to be replaced, thereby temporarily limiting the stirring head 133 to be replaced; and then the first sliding cylinder 432 drives the corresponding stirring head 133 to be replaced. After the personnel unscrew the fastening bolts connecting the shaft sleeve 1331 of the stirring head 133 and the stirring shaft 131 from the shaft sleeve 1331, the support ring 41 is driven by the first lifting cylinder 42 to move the stirring head 133 to be replaced downward until the stirring head 133 to be replaced is separated from the stirring shaft 131, and the removal of the stirring head 133 is completed. This is conducive to the smooth separation of the stirring head 133 to be replaced from the stirring head 133, and reduces the situation where the stirring head 133 directly falls off from the stirring shaft 131 to the slide 21 after the fastening bolts on the shaft sleeve 1331 are unscrewed.

[0042] At the same time, when a new stirring head 133 is replaced later, the shaft sleeve 1331 of the new stirring head 133 can be placed between several clamping blocks 431 on the support ring 41, and the corresponding clamping blocks 431 can be driven by the first sliding cylinder 432 to press against the outer periphery of the shaft sleeve 1331 of the new stirring head 133, so that the shaft sleeve 1331 at the new stirring head 133 is opposite to the stirring shaft 131, so as to realize the rapid positioning of the new stirring head 133, and then the first lifting cylinder 42 drives the support ring 41 to drive the new stirring head 133 to move upward until the shaft sleeve 1331 of the new stirring head 133 is inserted into the stirring shaft 131, and the support ring 41 is used to cooperate with the clamping assembly to insert the new stirring head 133 into the rear end of the stirring shaft 131 and temporarily limit it, so that the operator can fix the shaft sleeve 1331 of the new stirring head 133 on the stirring shaft 131 by tightening the bolts.

[0043] By embedding the first sliding cylinder 432 in the corresponding installation groove 411 on the support ring 41, it is helpful to limit the interference between the first sliding cylinder 432 and the stirring blade 1332 of the stirring head 133 during the subsequent upward movement of the support ring 41.

[0044] Reference Figure 5 and Figure 6 The slide 21 is also provided with a shaft clamping assembly for clamping the stirring shaft 131. The shaft clamping assembly includes two shaft clamping parts 5. The two shaft clamping parts 5 are respectively located on opposite sides of the outer circumference of the support ring 41, and the shaft clamping parts 5 are arranged higher than the support ring 41. The shaft clamping parts 5 are all arranged axially toward the support ring 41. The shaft clamping part 5 includes a shaft clamping frame 51. A shaft clamping block 52 is supported on the shaft clamping frame 51. The shaft clamping block 52 is provided with a semicircular arc groove 521 on one side of the shaft clamping block 52 facing the axial direction of the support ring 41. The semicircular arc groove 521 is used for the stirring shaft 131 to be embedded. The shaft clamping frame 51 is also provided with a second sliding drive member for driving the shaft clamping block 52 to move toward or away from the axial direction of the stirring shaft 131. Specifically, the second sliding drive member includes a second sliding cylinder 53. The second sliding cylinder 53 is arranged axially toward the support ring 41 and the piston rod of the second sliding cylinder 53 is connected to the shaft clamping block 52, so as to realize the driving connection between the second sliding drive member and the shaft clamping block 52.

[0045] Through the setting of the clamping shaft assembly, when the stirring head 133 located at the tail end of the stirring shaft 131 is subsequently removed, the second sliding cylinders 53 of the two clamping shaft parts 5 first drive the corresponding clamping shaft block 52 to move in the axial direction close to the support ring 41 until the semicircular arc groove 521 at the clamping shaft block 52 is fitted to the outer periphery of the stirring shaft 131. The two clamping shaft blocks 52 are used to cooperate to support and limit the stirring shaft 131, which is beneficial to limit the deformation of the stirring shaft 131 caused by force when the stirring head 133 located at the tail end of the stirring shaft 131 is subsequently disassembled and assembled.

[0046] Two second lifting driving members are supported on the brackets 410 of the two clamping shaft parts 5 of the slide 21. The second lifting driving member includes a second lifting cylinder 6 vertically supported on the slide 21. The second lifting cylinder 6 is located below the clamping shaft frame 51 of the corresponding clamping shaft part 5. The piston rod of the second lifting cylinder 6 is connected to the bottom of the clamping shaft frame 51. When the first lifting cylinder 42 drives the support ring 41 to drive the stirring head 133 to move downward, the two second lifting cylinders 6 drive the clamping shaft frame 51 to drive the clamping shaft block 52 to move downward synchronously, so that the two clamping shaft blocks 52 can be used to scrape off the debris adhering to the installation position of the sleeve 1331 of the stirring shaft 131 from the stirring shaft 131, so as to facilitate the subsequent insertion of the sleeve 1331 of the new stirring head 133 into the stirring shaft 131.

[0047] The implementation principle of the embodiment of the present application is as follows: when switching the stirring head 133 of the stirrer 13 with different blades, firstly, the kettle cover 12 is driven by two lifting cylinders 3 to drive the stirrer 13 upwardly away from the kettle body 11, and then the kettle body 11 is driven by the electric screw module 2 to slide horizontally to be staggered with the kettle cover 12, and at the same time, the auxiliary disassembly and assembly mechanism 4 is located below the kettle cover 12, and after the kettle cover 12 is driven by two lifting cylinders 3 to drive the stirrer 13 to approach the auxiliary disassembly and assembly mechanism 4, the auxiliary disassembly and assembly mechanism 4 cooperates with manual work to complete the disassembly and assembly of the stirring head 133 at the tail end of the stirring shaft 131, so as to realize the switching of the stirring heads 133 of different blades of the stirrer 13. There is no need for the operator to enter the reactor to perform the operation, which makes the switching operation of the stirring heads 133 of different blades of the reactor stirrer 13 simpler and more convenient.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
