Description

Technical Field

[0001] This utility model relates to the field of menthol processing, and more specifically, to a menthol crude oil heating device. Background Technology

[0002] Currently, raising the temperature of menthol raw materials through water bath heating can maintain a constant temperature, effectively improving the crystallization effect of menthol. During the crystallization process, stirring the liquid raw materials can accelerate the purification of menthol raw materials. However, after crystallization, menthol forms long needle-like crystals that adhere to the inner wall of the crystallization tank. Currently, the menthol raw materials are stirred by stirring rods. After the upper layer of raw materials evaporates and crystallizes, the stirring rods collide with the already crystallized menthol crystals, causing the menthol crystals to break and fall back into the liquid menthol raw materials, affecting the efficiency of menthol crystallization and the shape of the crystallized product. Utility Model Content

A rotating mechanism is installed on the outer wall of the water bath heating tank and inside the water bath chamber to drive the concentration crystallization tank to rotate within the water bath chamber. The concentration crystallization tank rotates within the water bath chamber via the rotating mechanism. A stirring component for stirring the raw material is provided inside the concentration crystallization tank. The stirring component rotates synchronously with the rotation of the concentration crystallization tank. The stirring component is hollow inside and communicates with the inside of the water bath chamber. The heated fluid inside the water bath chamber enters the stirring component and stirs and heats the raw material as the concentration crystallization tank rotates.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0018] As shown in Figures 1-3, a menthol crude oil heating device includes a water bath heating tank 1 and a concentration crystallization tank 2. A water bath chamber 3 is formed between the water bath heating tank 1 and the concentration crystallization tank 2. A rotating mechanism 4 is installed on the outer wall of the water bath heating tank 1 and inside the water bath chamber 3 to drive the concentration crystallization tank 2 to rotate within the water bath chamber 3. The concentration crystallization tank 2 rotates within the water bath chamber 3 via the rotating mechanism 4. A stirring component 5 for stirring the raw material is provided inside the concentration crystallization tank 2. The stirring component 5 rotates synchronously with the rotation of the concentration crystallization tank 2. The stirring component 5 is hollow inside and communicates with the inside of the water bath chamber 3. The heated fluid in the water bath chamber 3 enters the stirring component 5 and stirs and heats the raw material as the concentration crystallization tank 2 rotates.

[0019] During operation, heating fluid is injected into the water bath chamber 3 to create a constant-temperature heating environment. The rotating mechanism 4 drives the concentration crystallization tank 2 to rotate as a whole within the water bath chamber 3. The stirring component 5 inside the tank rotates synchronously with the concentration crystallization tank 2, thereby stirring the raw materials. Simultaneously, the heating fluid in the water bath chamber 3 enters the hollow stirring component 5 through the connecting structure, transferring heat to the raw materials through the component wall during the stirring process. Unlike traditional devices where the stirring rod rotates independently of the concentration crystallization tank 2, in this device, the stirring component 5 rotates as a whole with the concentration crystallization tank 2, and its direction of movement is consistent with the overall flow trend of the raw materials inside the tank. This significantly reduces rigid collisions with the crystallized menthol and avoids the breakage problem caused by direct impact of the needle-shaped crystals due to the independent high-speed rotation of the traditional stirring rod.

[0020] Based on the above, this device achieves simultaneous heating and stirring, improving raw material processing efficiency; through the structural design of "tank body driving the stirring component 5 to rotate as a whole", it fundamentally reduces the impact on crystallization, protects the morphology of menthol crystals, and solves the problem of traditional stirring rods damaging crystals.

[0021] A mechanical sealing ring 6 is connected between the top of the concentration crystallization tank 2 and the water bath heating tank 1, and the concentration crystallization tank 2 is movably connected to the water bath heating tank 1 through the mechanical sealing ring 6; a number of support rods 7 facing the concentration crystallization tank 2 are installed on the inner wall of the water bath heating tank 1, and the ends of the support rods 7 are embedded with ball bearings 8 that fit against the outer wall of the concentration crystallization tank 2.

[0022] Based on the above, the mechanical seal ring 6 forms a seal at the top connection between the concentration crystallization tank 2 and the water bath heating tank 1, which allows the concentration crystallization tank 2 to rotate freely (movable connection) and prevents the heating fluid in the water bath chamber 3 from leaking; the support rod 7 and the end ball bearing 8 on the inner wall of the water bath heating tank 1 fit against the outer wall of the concentration crystallization tank 2, providing radial support for the rotation of the concentration crystallization tank 2, reducing the shaking of the concentration crystallization tank 2 during rotation, ensuring that the stirring assembly 5 inside the tank rotates smoothly with the concentration crystallization tank 2, and avoiding additional collisions between the stirring assembly 5 and the crystal inside the tank due to the shaking of the concentration crystallization tank 2.

[0023] The rotating mechanism 4 includes a toothed ring 9 located in the water bath chamber 3, a crown tooth 10 meshing with the toothed ring 9, and a servo motor 11 installed on the outer wall of the water bath heating tank 1. The output shaft end of the servo motor 11 is connected to a reducer 12, and the output shaft of the reducer 12 extends through the tank body of the water bath heating tank 1 into the interior of the water bath chamber 3.

[0024] Based on the above, the servo motor 11 provides power, which is reduced in speed by the reducer 12 and drives the output shaft to rotate. The crown tooth 10 at the end of the output shaft meshes with the gear ring 9 fixed on the outer wall of the concentration crystallization tank 2, transmitting power to the concentration crystallization tank 2 and driving the concentration crystallization tank 2 and the internal stirring assembly 5 to rotate synchronously. Through gear meshing transmission, the rotation speed of the concentration crystallization tank 2 can be precisely controlled, so that the stirring intensity of the stirring assembly 5 matches the state of the raw material (such as viscosity and degree of crystallization), avoiding violent collision between the stirring assembly 5 and the crystals due to excessive speed, or uneven stirring of the raw material due to excessively slow speed.

[0025] Furthermore, the rotation speed of the concentration crystallizer 2 can be precisely adjusted by the servo motor 11 to adapt to different process requirements, further reducing the risk of rigid collision between the stirring component 5 and the crystallizer, while ensuring the uniformity of raw material mixing.

[0026] The crown gear 10 is installed at the end of the output shaft of the reducer 12, and the gear ring 9 is fixed on the outer wall of the concentration crystallization tank 2. A mechanical seal 13 is provided at the connection between the output shaft of the reducer 12 and the outer wall of the water bath heating tank 1. The crown gear 10 and the gear ring 9 directly mesh to ensure that the power is efficiently transmitted to the concentration crystallization tank 2, driving the concentration crystallization tank 2 and the internal stirring assembly 5 to rotate stably. The mechanical seal 13 at the connection between the output shaft of the reducer 12 and the outer wall of the water bath heating tank 1 can prevent the heating fluid in the water bath chamber 3 from leaking through the shaft, ensuring the sealing of the device during rotation, so that the heating fluid can be stably retained in the water bath chamber 3 and the stirring assembly 5 to continuously heat the raw materials.

[0027] The stirring assembly 5 includes a stirring tube 14 that extends spirally inside the concentration crystallization tank 2. The top end of the stirring tube 14 is connected to a first external threaded connector tube 15 that extends toward the inner wall of the concentration crystallization tank 2, and the bottom end of the stirring tube 14 is connected to a second external threaded connector tube 16 that extends upward to the height of the first external threaded connector tube 15 and then toward the inner wall of the concentration crystallization tank 2.

[0028] Based on the above, when the spiral stirring tube 14 rotates as a whole with the concentration crystallization tank 2, its spiral structure can guide the raw material to flow up and down along the tank wall, achieving uniform stirring. Compared with the traditional independently set stirring rod, the spiral stirring tube 14 rotates synchronously with the tank body, and its direction of movement is consistent with the flow direction of the raw material in the tank due to centrifugal force. The relative speed between the two is low, which can significantly reduce the collision force and frequency with the crystallized menthol, avoiding crystal breakage. The first external threaded connector tube 15 and the second external threaded connector tube 16 fix the spiral stirring tube 14 to the inner wall of the concentration crystallization tank 2, ensuring the structural stability of the stirring tube 14 when it rotates with the tank body.

[0029] The inner wall of the concentration crystallization tank 2 is equipped with a third external threaded connector 17 that mates with the first external threaded connector 15 and a fourth external threaded connector 18 that mates with the second external threaded connector 16. Both the third external threaded connector 17 and the fourth external threaded connector 18 are connected to the inside of the water bath chamber 3. A first internal threaded tube 19 is sleeved on the outside of the connection between the first external threaded connector 15 and the third external threaded connector 17, and a second internal threaded tube 20 is sleeved on the outside of the connection between the second external threaded connector 16 and the fourth external threaded connector 18.

[0030] Based on the above, the first external threaded connector 15 and the third external threaded connector 17 are fitted together, and the second external threaded connector 16 and the fourth external threaded connector 18 are fitted together, forming a communication channel between the spiral stirring tube 14 and the water bath chamber 3. The externally fitted first internal threaded tube 19 and the second internal threaded tube 20 are sealed by threaded connection, ensuring that the heating fluid in the water bath chamber 3 can enter the first external threaded connector 15 through the third external threaded connector 17, then flow into the spiral stirring tube 14, and finally return to the water bath chamber 3 through the second external threaded connector 16 and the fourth external threaded connector 18, forming a closed loop circulation. During the rotation of the spiral stirring tube 14 with the tank, this sealing structure ensures that the heating fluid does not leak, so that the stirring tube 14 is always filled with high-temperature fluid, continuously transferring heat to the raw material, while avoiding fluid leakage and contamination of the raw material.

[0031] Furthermore, the combination of the external threaded connector and the internal threaded connector enables a detachable connection, facilitating the separate disassembly of the spiral stirring tube 14 for cleaning or replacement, thus reducing maintenance difficulty; the reliable sealing structure ensures stable circulation of the heating fluid and improves heat transfer efficiency; the structural design is adapted to the tank rotation condition and does not affect the coordination of the spiral stirring tube 14 with the tank rotation.

[0032] The water bath chamber 3 is also equipped with a miniature water pump 21, and the output end of the miniature water pump 21 is connected to the third external threaded connector pipe 17 through a pipeline.

[0033] Based on the above, the micro water pump 21 provides power to the heating fluid in the water bath chamber 3, driving the fluid through the pipeline, the third external threaded connector 17, and the first external threaded connector 15 into the spiral stirring tube 14, and then back to the water bath chamber 3 through the second external threaded connector 16 and the fourth external threaded connector 18, accelerating the circulation speed of the heating fluid in the stirring tube 14. While the spiral stirring tube 14 rotates with the tank to stir the raw material, the rapidly circulating high-temperature fluid fully exchanges heat with the raw material through the tube wall, improving heating efficiency; and the fluid circulation speed can be adjusted by the water pump power to match the stirring intensity (tank rotation speed), ensuring uniform heating of the raw material and reducing abnormal crystallization caused by local overheating.

[0034] Furthermore, the micro water pump 21 accelerates the circulation of the heating fluid, improves heat transfer efficiency, and shortens the heating time of the raw materials; the fluid circulation speed is controllable and adapts to different process requirements in conjunction with the stirring intensity, further ensuring the crystallization quality; it avoids the problem of uneven temperature in the stirring tube 14 caused by fluid stagnation, and the liquid outlet pipe 22 and liquid inlet pipe 23 are used to replace the heating fluid in the water bath chamber 3.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
