DETAILED DESCRIPTION

[0023] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0024] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a chemical reaction kettle with graded uniform stirring, comprising a kettle body 1, a kettle cover 2 is installed on the top of the kettle body 1 by bolts, a feed pipe 3 is integrally formed on the kettle cover 2, and a mounting seat 4 is fixed by welding in the middle of the kettle cover 2, a rotating connecting shaft 5 is arranged in the middle of the kettle cover 2, the connecting shaft 5 extends into the interior of the kettle body 1, and the connecting shaft 5 is located in the mounting seat 4, when a driver is installed on the mounting seat 4, the driver output shaft is connected to the connecting shaft 5, a discharge pipe 6 is welded at the bottom of the kettle body 1, a graded stirring structure 7 is arranged inside the kettle body 1, and the graded stirring structure 7 is connected and fixed to the connecting shaft 5;

[0025] The chemical raw materials are put into the kettle body 1 through the feed pipe 3, and then the driver is turned on to rotate the connecting shaft 5, and then the graded stirring structure 7 is driven to rotate, so that the chemical raw materials in the kettle body 1 are mixed and stirred.

[0026] See also Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The utility model provides a chemical reactor with graded uniform stirring. The graded stirring structure 7 includes a connecting rotating rod 71. The upper end surface of the connecting rotating rod 71 is integrally formed with an insert block 701. The upper end of the connecting rotating rod 71 is connected and fixed to the connecting shaft 5 through a flange. At the same time, the insert block 701 will be inserted into the connecting shaft 5. After the insert block 701 is inserted into the interior of the connecting shaft 5, the connecting rotating rod 71 can be spliced ​​with the connecting shaft 5 in a vertical state, and when the connecting rotating rod 71 rotates, the stability of the connection is improved by the inhibition of the insert block 701, which effectively inhibits the rotating rod 71 from tilting during rotation and reduces jitter. A connecting sleeve 72 is assembled on the connecting rotating rod 71. Two connecting sleeves 72 are provided and are both arranged on the connecting rotating rod 71, and are respectively located in the middle and lower ends of the connecting rotating rod 71. A propulsion stirring blade 73 is integrally formed on the middle connecting sleeve 72. The propulsion stirring blade When rotating, 73 can push the chemical raw materials in the middle of the kettle body 1 downward, so that the chemical raw materials in the middle of the kettle body 1 are mixed with the chemical raw materials in the lower part. At the same time, when the propulsion stirring blade 73 rotates, the chemical raw materials are also mixed and stirred. The propulsion stirring blade 73 has a primary mixing effect. The lower end connecting sleeve 72 is integrally formed with a mixing stirring blade 74. The mixing stirring blade 74 can mix and stir the chemical raw materials at the bottom of the kettle body 1 during rotation. The mixing stirring blade 74 has a secondary mixing effect. When the propulsion stirring blade 73 pushes the chemical raw materials into the lower part of the kettle body 1, the mixing stirring blade 74 mixes and stirs them again, thereby improving the mixing and stirring effect, reducing the mixing and stirring time and improving the work efficiency. Since the propulsion stirring blade 73 and the mixing stirring blade 74 are both fixed on the connecting rotating rod 71, they will rotate synchronously, and there will be no uneven stirring effect, so as to achieve graded uniform stirring.

[0027] The connecting sleeve 72 is composed of a first clamping sleeve 721 and a second clamping sleeve 722. The surfaces where the first clamping sleeve 721 and the second clamping sleeve 722 fit together are integrally formed with a second clamping block 729. The second clamping block 729 will be inserted into the second clamping sleeve 722 to avoid the problem of misalignment after the first clamping sleeve 721 and the second clamping sleeve 722 are spliced. Bolt positioning holes 723 are provided on the first clamping sleeve 721 and the second clamping sleeve 722. Bolts 724 threadedly connected to the bolt positioning holes 723, and the bolts 724 pass through the connecting plate 725. The bolts 724 pass through the connecting plate 725 and are threadedly connected to the bolt positioning holes 723. The connecting plate 725 is fixed on the first ferrule 721 and the second ferrule 722, and connected by the connecting plate 725, so that the first ferrule 721 and the second ferrule 722 can be fixed after being spliced, and the lower end of the bolt positioning hole 723 is connected with a docking column 726, and the docking column 726 is arranged on the second connecting plate 727, and the bolt 724 is threadedly connected with the end of the docking column 726. When the bolt 724 is threadedly connected with the docking column 726, the second connecting plate 727 will be connected to the bottom of the first ferrule 721 and the second ferrule 722, so as to avoid the phenomenon of unstable connection at the lower ends of the first ferrule 721 and the second ferrule 722;

[0028] A clamping block 728 is provided on the surface where the first clamping sleeve 721 and the second clamping sleeve 722 are combined with the connecting rotating rod 71, and the clamping block 728 is connected to the connecting rotating rod 71, thereby improving the transmission effect;

[0029] When it is necessary to disassemble the first ferrule 721 or the second ferrule 722 separately, turn the bolt 724 to separate it from the bolt positioning hole 723, and then take it out of the connecting plate 725, so that the connecting plate 725 releases the splicing and fixation of the first ferrule 721 and the second ferrule 722. Then the staff can remove the first ferrule 721 and the second ferrule 722 for disassembly, so as to achieve the beneficial effect of being able to disassemble separately when the propulsion stirring blade 73 or the mixing stirring blade 74 is damaged.
