[0027] It further includes: distributing assembly 3, distributing assembly 3 includes guide bend 31 connected on kettle cover 11 and connected with the bottom of feed inlet 12 and distributing cover 32 sleeved on stirring rod 23;
[0028] Specifically, a distribution funnel 33 is arranged in the port of the distribution cover 32, the outer wall surface of the distribution cover 32 is a conical surface, the bottom surface of the distribution funnel 33 and the conical surface are provided with a plurality of distribution grooves 331, the guide bend pipe 31 is divided into a guide section one 301 and a guide section two 302, the bottom port of the guide section one 301 is aligned with the distribution cover 32, the bottom port of the guide section two 302 is aligned with the distribution funnel 33, by uniquely dividing the guide bend pipe 31 into the guide section one 301 and the guide section two 302, the design ensures the distribution of the raw materials: part of the raw materials is guided to the outer wall conical surface of the distribution cover 32 through the guide section one 301, and the other part enters the distribution funnel 33 through the guide section two 302. Then, the direct-current servo motor 21 is started, which not only drives the stirring rod 23 to start rotating, but also synchronously drives the distribution cover 32 and the distribution funnel 33 in the distribution cover 32 to rotate. This action enables the raw materials falling into the distribution funnel 33 to be evenly distributed in the inside of the kettle body 1 by means of the plurality of distribution grooves 331 on the distribution funnel 33. At the same time, the raw materials falling on the outer wall conical surface of the distribution cover 32 are also evenly scattered into the kettle body 1.

[0033] As shown in Figures 1 to 3As shown in the embodiment, it should be noted that the hydrolysis kettle in the application file is also provided with a control unit, a steam pipe, a slag discharge port, an aldehyde vapor outlet and other auxiliary components for use; the hydrolysis kettle is a commercially available product of the prior art, and the working principle is disclosed, which is used in combination with other equipment in the production of 2-ethylanthraquinone. In addition, it should be noted that the application file only improves the disadvantages of the existing continuous hydrolysis kettle for 2-ethylanthraquinone production, that is, the raw materials are prone to accumulation or caking, which affects the uniformity of the mixture of the raw materials and reduces the production quality of 2-ethylanthraquinone, and does not involve other aspects; the working principle of the continuous hydrolysis kettle for 2-ethylanthraquinone production is introduced as follows:
[0034] When the new scheme is used, first, the electric control valve on the feeding port 12 is opened, so that the raw materials enter the guide elbow 31. The guide elbow 31 is uniquely divided into two parts, guide section one 301 and guide section two 302, which ensures the distribution of the raw materials: part of the raw materials is guided to the outer wall taper surface of the distribution cover 32 through the guide section one 301, and the other part enters the distribution funnel 33 through the guide section two 302.
[0035] Then, the direct current servo motor 21 is started, which not only drives the stirring rod 23 to start rotating, but also synchronously drives the distribution cover 32 and the distribution funnel 33 inside it to rotate. This action enables the raw materials falling into the distribution funnel 33 to be evenly distributed in the inside of the kettle body 1 by means of the plurality of distribution grooves 331 thereon. At the same time, the raw materials falling on the outer wall taper surface of the distribution cover 32 are also evenly scattered into the kettle body 1. This design effectively avoids the accumulation of materials, significantly improves the uniformity of the overall mixing of the raw materials, and further optimizes the production quality of 2-ethylanthraquinone.
[0036] In addition, the new type also designs a cleaning structure. When the stirring rod 23 rotates, it will synchronously drive the U-shaped cleaning frame rod 4 to rotate, so that the cleaning blade 41 on the U-shaped cleaning frame rod 4 scrapes the inner wall of the kettle body 1, prevents the material from adhering to the inner wall, avoids waste of materials, and effectively reduces the burden of subsequent cleaning personnel.
[0037] The above embodiments are only used to illustrate the technical method of the present application, not to limit it.
