Description

Technical Field

[0001] This utility model relates to the field of material mixing technology, specifically to a mixing tank for real-time monitoring of liquid level. Background Technology

[0002] In the processing of Sichuan pepper oil (especially Sichuan pepper oil and Sichuan pepper essential oil prepared by extraction), the mixing tank is one of the key pieces of equipment. Its core function is to achieve thorough mixing of the Sichuan pepper oil raw material (or Sichuan pepper extraction raw material) and the extractant, providing a foundation for the subsequent material-liquid separation process. In existing technologies, mixing tanks are generally placed vertically to facilitate the discharge of the processed liquid, and each tank is equipped with an agitator. The operation of the agitator achieves uniform mixing of the liquid within the tank, and this structure has become a standard design in the industry.

[0003] However, in the actual feeding operation of the mixing tank, in order to ensure that the liquid in the tank achieves the ideal mixing effect during the agitation process, the feed rate needs to be controlled (too much feed rate can easily lead to overflow or insufficient agitation, while too little feed rate will reduce processing efficiency and affect the uniformity of mixing). Therefore, a liquid level monitor is usually installed on the mixing tank to guide the control of the feed rate by monitoring the liquid level in the tank in real time.

[0004] Currently, commonly used liquid level monitors in the industry (such as float-type liquid level detection devices based on the principle of buoyancy) all require insertion into the mixing tank and direct contact with the liquid. They rely on buoyancy to keep the detection component floating on the surface of the liquid, thus achieving real-time monitoring of the liquid level. While this monitoring method can meet the need for real-time liquid level feedback, it has significant drawbacks: because an agitator is already fixed inside the mixing tank, its agitating components are highly susceptible to collision with the liquid level monitor inserted into the tank during high-speed operation. This can not only damage the liquid level monitor and cause it to malfunction, but in severe cases, the mechanical failure caused by the collision can also affect the normal operation of the mixing tank. Furthermore, some mixing tanks, for ease of self-cleaning, typically have the agitator blades positioned close to the inner wall of the tank, making it impossible to install the liquid level monitor and thus preventing liquid level monitoring. Utility Model Content

[0005] Therefore, in order to solve the above-mentioned shortcomings, this utility model provides a mixing tank for real-time monitoring of liquid level. The mixing tank has an agitation mechanism inside the tank, which facilitates the agitation and mixing of the internal liquid. The liquid level detection rod is set at the center of the agitation mechanism in a liftable manner, which not only avoids the external stirring blades and facilitates real-time monitoring of the internal liquid, but also ensures that the blades are close to the inner wall of the tank, which facilitates the self-cleaning of the inner tank and effectively improves the practicality of the device.

[0006] This invention is achieved by a mixing tank for real-time liquid level monitoring, comprising an outer tank body, which is kept vertical by a column. The inner tank is placed inside the outer tank and has a feeding port at the top; The stirring mechanism is rotatably mounted inside the inner tank and remains coaxially aligned. The liquid level detection rod is raised and lowered and is located at the center of the agitation mechanism, with its top extending through the top of the agitation mechanism and its bottom extending through the bottom of the agitation mechanism and communicating with the inside of the inner tank. A buoyancy ball is installed at the bottom of the liquid level detection rod.

[0007] Preferably, the bottom of the inner tank is conical, and a discharge pipe is provided at the lowest point of the bottom. The discharge pipe extends to the outside of the outer tank and is equipped with a valve. A constant temperature medium coil is also provided on the outside of the inner tank. The constant temperature medium coil is located in the interlayer outside the inner tank and its two ends extend to the outside of the outer tank and are connected to the constant temperature medium source.

[0008] Preferably, the agitation mechanism includes, The stirring rod is coaxially mounted inside the inner tank and its top extends to the top of the inner tank, while its bottom is close to the inner bottom of the inner tank. Several stirring blades are evenly distributed on the stirring rod inside the inner tank and their ends are kept close to the inner wall of the inner tank. The drive motor is mounted on the top of the inner tank via a bracket and maintains a transmission connection with the agitator rod.

[0009] Preferably, the stirring rod is a hollow rod structure, and the upper part of the stirring rod is connected to the top of the inner tank and the support through a rotating connector. An inner cylinder is installed inside the stirring rod through the rotating connector, and the liquid level detection rod passes through the inner cylinder and slides up and down.

[0010] Preferably, the external dimensions of the buoyancy ball are smaller than the internal dimensions of the agitator.

[0011] Preferably, the drive motor and the agitator are connected by a belt drive mechanism.

[0012] Preferably, the inner cylinder is fixed to the bracket by a top support.

[0013] Compared with the prior art, the present invention has the following advantages: This mixing tank features a liquid level detection rod that can be raised and lowered to the center of the stirring mechanism, completely avoiding the stirring blades and preventing damage to traditional monitoring instruments due to collisions. This ensures real-time liquid level monitoring and provides reliable data for precise control of the feed rate.

[0014] Meanwhile, the stirring blades can be close to the inner wall of the tank, and can scrape and clean the inner wall during operation, reducing material residue; this avoids cross-contamination between different batches of pepper oil, and saves the manual disassembly and cleaning steps, reducing labor and time costs.

[0016] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for illustration and explanation of this utility model and are not intended to limit this utility model in any way. The accompanying drawings in this utility model are only for illustrative purposes and to facilitate understanding of the embodiments and are not intended to limit this utility model in any way.

[0017] It should be noted that the structures, proportions, sizes, etc. shown in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which the present invention can be implemented. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0018] As described in the background section, existing mixing tanks, due to the presence of an internal agitator, cannot allow the insertion of a liquid level detection rod to monitor the liquid level in real time. This results in the inability to monitor the internal liquid level in real time, which may affect the mixing effect.

[0019] For the reasons stated above, please refer to the appendix for solutions to these problems. Figure 1 ~Appendix Figure 3 This utility model provides a mixing tank for real-time monitoring of liquid level, including an outer tank body 1, which is kept vertical by a column; The inner tank 2 is placed inside the outer tank 1 and has a feeding port 3 on the top; The stirring mechanism is rotatably installed inside the inner tank 2 and remains coaxially aligned. The liquid level detection rod 7 is raised and lowered and is located at the center of the agitation mechanism, with its top extending through the top of the agitation mechanism and its bottom extending through the bottom of the agitation mechanism and communicating with the inside of the inner tank 2. A buoyancy ball 11 is provided at the bottom of the liquid level detection rod 7.

[0020] In this embodiment, the bottom of the inner tank 2 is conical, and a discharge pipe 4 is provided at the lowest point of the bottom. The discharge pipe 4 extends to the outside of the outer tank 1 and is equipped with a valve. A constant temperature medium coil 8 is also provided on the outside of the inner tank 2. The constant temperature medium coil 8 is located in the interlayer outside the inner tank 2 and its two ends extend to the outside of the outer tank 1 and are connected to the constant temperature medium source.

[0021] As mentioned above, setting up a constant temperature medium coil facilitates temperature control of the internal liquid, thereby effectively ensuring the mixing quality of the liquid.

[0022] Furthermore, the constant temperature medium coil is configured as a spiral tube structure, in which the constant temperature medium flowing inside transfers heat to the liquid inside the inner tank through heat conduction, thereby achieving temperature control of the liquid.

[0023] Please see the appendix Figure 5 In this embodiment, the agitation mechanism includes, The stirring rod 9 is coaxially mounted inside the inner tank 2 and its top extends above the inner tank 2, while its bottom is close to the inner bottom of the inner tank 2. Several stirring blades 10 are evenly distributed on the stirring rod 9 inside the inner tank 2 and their ends are kept close to the inner wall of the inner tank 2; The drive motor 6 is mounted on the top of the inner tank 2 via the bracket 5 and is connected to the agitator rod 9 for transmission.

[0024] Please refer to the appendix carefully. Figure 3 and attached Figure 4In this embodiment, the stirring rod 9 is a hollow rod structure. The upper part of the stirring rod 9 is connected to the top of the inner tank 2 and the bracket 5 through a rotating connector. An inner cylinder 13 is installed inside the stirring rod 9 through a rotating connector. The liquid level detection rod 7 passes through the inner cylinder 13 and slides up and down.

[0025] As mentioned above, the shape of the agitator rod facilitates the installation of the liquid level detection rod inside. By setting an inner cylinder, the rotation of the agitator rod during rotation can be prevented from affecting the real-time raising and lowering of the liquid level detection rod.

[0026] In this embodiment, the external dimensions of the buoyancy ball 11 are smaller than the internal dimensions of the agitator rod 9.

[0027] As mentioned above, the size of the buoyancy ball is set to ensure that it can rise and fall inside the agitator rod, thereby enabling real-time monitoring of the internal liquid level.

[0028] Please see the appendix Figure 6 In this embodiment, the drive motor 6 and the stirring rod 9 are connected by a belt transmission mechanism 12.

[0029] As described above, a belt drive mechanism can be used to drive the hollow agitator rod to rotate via a drive motor.

[0030] Please continue to refer to the appendix. Figure 6 In this embodiment, the inner cylinder 13 is fixed to the bracket 5 by a top support.

[0031] As mentioned above, the method of fixing the inner cylinder is to ensure that the liquid level lifting rod will not rotate with the inner cylinder, thus ensuring smooth lifting and lowering.

[0032] In this embodiment, a sensing probe is provided on the top of the liquid level detection rod 7, and a touch switch is provided at a preset height above the mixing tank. When the liquid level detection rod 7 rises to the corresponding height, its sensing probe contacts the touch switch, thereby achieving precise control of the internal liquid level.

[0033] In this embodiment, the liquid level detection rod 7 is provided with a scale line on the outside. When the internal liquid is drained, the liquid level detection rod 7 descends to the bottom and keeps the zero scale line flush with the support of the inner cylinder 13. The scale line allows external construction personnel to observe the liquid level inside in real time.

[0034] During use, the valve on the discharge pipe 4 is first closed, and the liquid is fed into the tank through the feed port 3. After the liquid enters the inner tank 2, the liquid level rises, causing the buoyancy ball 11 to rise and the liquid level detection rod 7 to rise until the appropriate liquid level is reached and feeding is stopped. Then, the drive motor 6 is started to drive the stirring rod 9 to rotate and stir the liquid inside. During the stirring process, the liquid in the center may drop a little due to the centrifugal force. This will not affect the monitoring of the liquid level. Just stop stirring to stop the liquid from being stirred.

[0035] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
