Description

Technical Field

[0001] This utility model relates to the technical field of anthracene oil crystallization, and in particular to an anthracene oil crystallization tank. Background Technology

[0002] Anthracene oil, a product of coal dry distillation, is a complex mixture containing various valuable organic compounds. Crystallization of anthracene oil can effectively separate important chemical raw materials such as anthracene, phenanthrene, and carbazole, which are indispensable in industries such as synthetic fibers, plastics, pharmaceuticals, pesticides, and dyes. For example, anthracene is used to produce anthraquinone dyes, and carbazole is an important intermediate in the synthesis of plastics and pesticides.

[0003] In existing technologies, anthracene oil crystallizers are typically equipped with a stirring device, driven by a motor to rotate the stirring shaft and the stirring blades on the shaft, thereby agitating the anthracene oil. However, during the crystallization process, the initial state of the anthracene oil, such as its composition, viscosity, and impurity content, varies considerably. In existing anthracene oil crystallizers, the angle between adjacent stirring blades is usually fixed, which cannot adapt to these different initial states of the anthracene oil. For example, when the anthracene oil has a high viscosity, the fixed-angle stirring blades cannot generate sufficient shear force and turbulence, resulting in uneven mixing of the material and localized oversaturation or undersaturation, affecting the quality and efficiency of crystallization. On the other hand, the relatively thin anthracene oil itself has good fluidity, and stirring with fixed-angle stirring blades in a conventional manner may lead to over-stirring, which not only wastes energy and increases production costs but may also damage the already formed microcrystalline structures, hindering the normal progress of the crystallization process. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, this utility model proposes an anthracene oil crystallizer that can adaptively adjust the angle between adjacent stirring blades, so as to flexibly adjust according to different initial states of anthracene oil, thereby achieving effective crystallization stirring of anthracene oil under different initial states, improving product quality and production efficiency.

[0006] To achieve the above objectives, this utility model proposes an anthracene oil crystallization tank, comprising a tank body, a stirring shaft, multiple stirring devices, a heating and cooling device, and a feeding and discharging device. The tank body is cylindrical, and the stirring devices, heating and cooling device, and feeding and discharging device are all connected to the tank body. The stirring shaft is vertically arranged along the central axis of the tank body, with its top end passing through the top of the tank body and connected to a drive motor, and its other end extending into the interior of the tank body. Multiple stirring devices are respectively installed on the portion of the stirring shaft located within the tank body, and are evenly distributed from top to bottom. Each stirring device includes multiple stirring blades and an angle adjustment mechanism, wherein the multiple stirring blades are respectively mounted on the stirring shaft via the angle adjustment mechanism.

[0007] The anthracene oil crystallizing tank of this invention can adaptively adjust the angle between adjacent stirring blades, so as to flexibly adjust according to different initial states of anthracene oil, thereby achieving effective crystallization stirring of anthracene oil under different initial states, improving product quality and production efficiency.

[0008] In addition, the anthracene oil crystallizer proposed in this application may also have the following additional technical features:

[0009] Specifically, the angle adjustment mechanism includes a fixed base, multiple adjusting rods, and multiple locking nuts. The fixed base is sleeved on the stirring shaft, and the fixed base is circular, with its center coinciding with the axis of the stirring shaft. A fixing groove adapted to the root of the stirring blade is formed on the outer circumference of the fixed base. Multiple insertion holes are formed along the circumference of the top and bottom of the fixed base, with one end of each insertion hole communicating with the fixing groove, and the insertion holes at the top and bottom of the fixed base corresponding one-to-one. At least two fixing holes corresponding to the insertion holes are formed at the root of the stirring blade. The multiple adjusting rods pass through the insertion holes and the fixing holes and are threadedly connected to the locking nuts.

[0010] Specifically, the fixed base is fixed to the stirring shaft by bolts.

[0011] Specifically, the heating and cooling device adopts a coil structure, and the coil is located on the inner wall of the tank.

Detailed Implementation

[0022] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0023] The anthracene oil crystallizing tank of this utility model embodiment will be described below with reference to the accompanying drawings.

[0024] The anthracene oil crystallizing tank provided by this utility model is mainly used in the crystallization process of anthracene oil. It can adaptively adjust the angle between adjacent stirring blades so as to flexibly adjust according to different initial states of anthracene oil, thereby achieving effective crystallization stirring of anthracene oil under different initial states, improving product quality and production efficiency.

[0025] like Figures 1-5 As shown, the anthracene oil crystallizing tank of this utility model embodiment may include a tank body 1, a stirring shaft 2, multiple stirring devices 3, a heating and cooling device 4, and a feeding and discharging device 5.

[0026] The tank 1 is cylindrical. The stirring device 3, the heating and cooling device 4, and the feeding and discharging device 5 are all connected to the tank 1. The stirring shaft 2 is vertically arranged along the central axis of the tank 1. The top end of the stirring shaft 2 passes through the top of the tank 1 and is connected to the drive motor 6. The other end of the stirring shaft 2 extends into the interior of the tank 1. Multiple stirring devices 3 are respectively installed in the part of the stirring shaft 2 located inside the tank 1, and the multiple stirring devices 3 are evenly distributed from top to bottom.

[0027] The stirring device 3 may include a plurality of stirring blades 31 and an angle adjustment mechanism 32, wherein the plurality of stirring blades 31 are respectively mounted on the stirring shaft 2 through the angle adjustment mechanism 32.

[0028] It should be noted that the tank 1 described in this embodiment adopts a cylindrical design and is welded from steel plates with certain strength and sealing performance. The tank 1 serves as the main body of the entire crystallization tank and provides an installation base for other components. The stirring device 3, heating and cooling device 4, and feeding and discharging device 5 are all connected to the tank 1, together forming the working system for anthracene oil crystallization.

[0029] In one embodiment of the present invention, the drive motor 6 is fixedly mounted on the top of the tank 1, and the output shaft of the drive motor 6 is coaxially connected to one end of the stirring shaft 2 via a coupling.

[0030] In one embodiment of the present invention, the angle adjustment mechanism 32 may include a fixed base 321, a plurality of adjusting rods 322 and a plurality of locking nuts 323.

[0031] The fixing seat 321 is sleeved on the stirring shaft 2. The fixing seat 321 is circular, and the center of the fixing seat 321 coincides with the axis of the stirring shaft 2. The outer circumferential surface of the fixing seat 321 is provided with a fixing groove 325 that is adapted to the root of the stirring blade 31. Multiple insertion holes 324 are provided on the top and bottom of the fixing seat 321 along its circumferential direction. One end of each insertion hole 324 is connected to the fixing groove 325, and the insertion holes 324 on the top and bottom of the fixing seat 321 correspond one-to-one. At least two fixing holes 326 corresponding to the insertion holes 324 are provided at the root of the stirring blade 31. Multiple adjusting rods 322 pass through the insertion holes 324 and the fixing holes 326 respectively and are threadedly connected to the locking nut 323.

[0032] Specifically, by loosening or tightening the locking nut 323, the adjusting rod 322 can be moved along the insertion hole 324, thereby changing the included angle between adjacent stirring blades 31. The included angle adjustment range is 30°-60°, realizing flexible adjustment of the angle of the stirring blades 31.

[0033] In one embodiment of this utility model, the fixed base 321 is fixed to the stirring shaft 2 by bolts.

[0034] In one embodiment of this utility model, the heating and cooling device 4 adopts a coil structure, and the coil is disposed on the inner wall of the tank 1.

[0035] Specifically, by introducing a heating or cooling medium into the coil, the temperature of the anthracene oil material in tank 1 is controlled to meet the temperature requirements at different stages of the anthracene oil crystallization process.

[0036] In one embodiment of the present invention, the feeding and discharging device 5 includes a feeding port 51 and a discharging port 52. The feeding port 51 is located on the side of the upper part of the tank body 1, and the discharging port 52 is located at the center of the bottom of the tank body 1. The feeding port 51 and the discharging port 52 are respectively connected to the tank body 1 through pipes 53, and valves and flow meters are respectively installed on the pipes 53.

[0037] Specifically, valves are used to control the inflow and outflow of materials, while flow meters can monitor the material flow rate in real time, ensuring precise control of the material inflow and outflow process.

[0038] Specifically, in a certain anthracene oil crystallization production scenario, using the anthracene oil crystallization tank of this utility model, relevant personnel first install and fix the tank body 1 according to the design requirements to ensure its stability. Then, based on the initial state of the anthracene oil, such as viscosity and composition, if the viscosity of the anthracene oil is found to be high, the locking nut 323 can be loosened, and the adjusting rod 322 can be moved within the insertion hole 324 to increase the included angle between adjacent stirring blades 31. Then, the locking nut 323 is tightened to enhance the stirring effect. Subsequently, a certain amount of anthracene oil is transported into the tank body 1 through the feed port 51, and the drive motor 6 is turned on to drive the stirring shaft 2 and stirring blades 31 to rotate. During the stirring process, at the same time, according to the anthracene oil crystallization process requirements, a suitable hot or cold medium is introduced through the coil of the heating and cooling device 4 to control the temperature of the anthracene oil in the tank body 1. For example, in the early stage of crystallization, a higher temperature hot medium is introduced to make the anthracene oil reach a suitable dissolution temperature. During the crystallization process, the temperature is gradually reduced to allow the target components in the anthracene oil to crystallize and precipitate.

[0039] Once crystallization is complete, open the valve at the discharge port 52. The crystallized material flows out through the discharge port 52 and then through the pipe 53 under the influence of gravity. The discharge volume is monitored by a flow meter to ensure the smooth discharge process.

[0040] The twisted cross-section design and spiral distribution of the stirring blades 31 enable the blades to exert forces on the material in different directions during the stirring process, causing the material to form a complex three-dimensional flow in the tank and enhancing the stirring effect.

[0041] As a possible alternative, a conical anti-clogging funnel and internally rotatable crushing blades can also be installed at the discharge port 52 to prevent material from clogging the discharge port 52 and ensure the continuity of the production process.

[0042] In summary, the anthracene oil crystallizer of this utility model embodiment can adaptively adjust the angle between adjacent stirring blades, so as to flexibly adjust according to different initial states of anthracene oil, thereby achieving effective crystallization stirring of anthracene oil under different initial states, improving product quality and production efficiency.
