Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0025] See also Figure 1-4 The present embodiment provides the following technical solution: a hydrolysis kettle for processing uniformly mixed chemical products, comprising a kettle body 1 and a kettle cover 2 movably arranged on the top of the kettle body 1. In the present embodiment, the kettle cover 2 is fixedly connected to the kettle body 1 by a lock, so that the kettle cover 2 can cover the kettle body 1.

[0026] A bottom stirring mechanism 3 is arranged at the bottom of the kettle body 1, and is used to mix and stir the materials at the bottom of the kettle body 1; a middle stirring mechanism 4 is arranged above the bottom stirring mechanism 3, and the middle stirring mechanism 4 is transmission-connected to the bottom stirring mechanism 3, and the middle stirring mechanism 4 is driven by a driving mechanism 5 arranged on the kettle cover 2. Through the bottom stirring mechanism 3 and the middle stirring mechanism 4, the materials in the kettle body 1 can be mixed and stirred by cooperating with each other.

[0027] The driving mechanism 5 includes an upper shaft 51 and a motor 52. The upper shaft 51 is rotatably connected to the kettle cover 2. The upper shaft 51 and the middle shaft 41 are fixedly connected via a first connecting flange. The motor 52 is fixedly arranged on the kettle cover 2 and is transmission-connected to the upper shaft 51. Through the motor 52, the middle stirring mechanism 4 and the bottom stirring mechanism 3 can be rotated at the same time, so as to better mix and stir the materials in the kettle body 1.

[0028] The central stirring mechanism 4 includes a central shaft 41, on which a sliding frame 42 is slidably connected, and a slide groove 43 is provided on the central shaft 41 for the sliding frame 42 to move in the vertical direction; a sliding sleeve 44, which is slidably sleeved on the outer wall of the central shaft 41, and the sliding sleeve 44 is fixedly connected to the sliding frame 42, and a central stirring blade 45 is fixedly provided on the side wall of the sliding sleeve 44; a telescopic component, which is used to pull the sliding frame 42 to reciprocate along the slide groove 43, and the telescopic component is connected to the sliding frame 42. Through the telescopic component, the central stirring mechanism 4 can stir the material while pulling the central stirring mechanism 4 to reciprocate in the vertical direction, thereby changing the stirring range of the central stirring mechanism 4, so that the material mixing and stirring can be more uniform, thereby overcoming the problem of insufficient reaction, thereby improving the mixing effect of the material.

[0029] The telescopic assembly includes a top plate 46 and a cylinder 47. The top plate 46 is fixedly arranged on the upper shaft 51. Cylinders 47 are fixedly arranged on both sides of the top plate 46 on the upper shaft 51. The piston rod of the cylinder 47 is fixedly connected to the sliding frame 42. Through the cylinder 47, while the top plate 46 and the sliding frame 42 rotate with the middle shaft 41, the sliding frame 42 can be pulled to reciprocate along the axial direction of the middle shaft 41.

[0030] The bottom stirring mechanism 3 includes a bottom shaft 31, which is fixedly connected to the middle shaft 41 through a second connecting flange. A first bottom stirring blade 32 is fixedly arranged at the lower part of the bottom shaft 31, and a second bottom stirring blade 33 is fixedly arranged on the bottom shaft 31 above the first bottom stirring blade 32. Through the bottom shaft 31, the first bottom stirring blade 32 and the second bottom stirring blade 33 can stir the material at the bottom of the kettle body 1 under the drive of the upper shaft 51 and the middle shaft 41.

[0031] It also includes a limiting mechanism 6 arranged on the upper shaft 51 and the bottom shaft 31, which is used to limit the upper shaft 51 and the bottom shaft 31, wherein the first limiting mechanism 6 on the upper shaft 51 includes a limiting plate 61, and the limiting plate 61 is rotatably arranged on the upper shaft 51, and a plurality of spaced limiting rods 62 are fixedly arranged on the side wall of the limiting plate 61, and the other end of the limiting rod 62 is connected to the inner wall of the kettle body 1 through a positioning assembly. Through the limiting rod 62 and the positioning assembly, the stability of the middle stirring mechanism 4 and the bottom mechanism when stirring materials inside the kettle body 1 can be increased, thereby avoiding the shaking phenomenon of the middle stirring mechanism 4 and the bottom stirring mechanism 3 when stirring materials.

[0032] It also includes a limiting mechanism 6 arranged on the upper shaft 51 and the bottom shaft 31, which is used to limit the upper shaft 51 and the bottom shaft 31, wherein the first limiting mechanism 6 on the upper shaft 51 includes a limiting plate 61, and the limiting plate 61 is rotatably arranged on the upper shaft 51, and a plurality of spaced limiting rods 62 are fixedly arranged on the side wall of the limiting plate 61, and the other end of the limiting rod 62 is connected to the inner wall of the kettle body 1 through a positioning assembly. Through the limiting rod 62 and the positioning assembly, the stability of the middle stirring mechanism 4 and the bottom mechanism when stirring materials inside the kettle body 1 can be increased, thereby avoiding the shaking phenomenon of the middle stirring mechanism 4 and the bottom stirring mechanism 3 when stirring materials.

[0033] In this embodiment, the upper limiting rod 62 and the lower limiting rod 62 are staggered with each other to avoid the middle stirring mechanism 4 and the lower stirring mechanism being unable to be placed into the kettle body 1 due to obstruction by the positioning component when the middle stirring mechanism 4 and the lower stirring mechanism are vertically placed into the middle part of the kettle body 1. This makes it convenient to position the middle stirring mechanism 4 and the lower stirring mechanism and to take and place the middle stirring mechanism 4 and the lower mechanism.

[0034] The positioning assembly includes an insert plate 63 and a positioning plate 64. The insert plate 63 is fixedly arranged on the limiting rod 62, and the positioning plate 64 is fixedly arranged on the inner wall of the kettle body 1. The other end of the positioning plate 64 is provided with a slot 65 adapted to the insert plate 63. Through the positioning plate 64 and the slot 65, after the limiting rod 62 enters the interior of the kettle body 1, the insert plate 63 can be inserted into the corresponding slot 65, so that the positioning plate 64 limits the limiting rod 62 in the vertical and horizontal directions, and when taking and placing the middle stirring mechanism 4 and the bottom stirring mechanism 3, it is easy to pull out or insert the insert plate 63 into the positioning groove.

[0035] The working principle of the utility model is as follows: after the material is added into the kettle body 1, the motor 52 is started, so that the upper shaft 51 drives the middle shaft 41 and the bottom shaft 31 to rotate, so that the middle stirring blade 45 and the bottom stirring blade mix and stir the material in the kettle body 1;

[0036] At the same time, the cylinder 47 is started, so that the cylinder 47 reciprocates and expands, and the sliding frame 42 pulls the middle shaft 41 to reciprocate vertically along the slide groove 43, so that the middle stirring blade 45 can reciprocate vertically while rotating, thereby changing the stirring range of the middle stirring blade 45.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
