Description

Technical Field

[0001] The invention belongs to the technical field of CBDV intermediate extraction, and particularly relates to a CBDV intermediate extraction device. Background Art

[0002] The CBDV intermediate extraction device is a device specially used to extract CBDV (cannabidiol valerate) intermediates from cannabis plants or their related raw materials. It uses a series of physical and chemical means such as extraction, separation and purification, and uses extraction units (such as Soxhlet extractors, supercritical CO2 extraction equipment, etc.) to dissolve CBDV from the raw materials, and then uses separation units (such as distillation towers, chromatography equipment), concentration units (such as rotary evaporators) and filtration units (such as filter paper, membrane filtration) to remove impurities, increase concentration and ensure product quality. It has the characteristics of high efficiency, selectivity, high degree of automation and safety, and provides relatively pure basic raw materials for the further processing and synthesis of subsequent CBDV related products.

[0003] At present, a Chinese patent with announcement number CN107311976B discloses an intermediate extraction device and method, including a crushing tower, an extraction tower, an extract collecting tower, and a distillation tower. A plurality of crushing rollers are arranged inside the crushing tower, and a sieve plate is arranged below the crushing roller. A stirring roller is arranged inside the extraction tower. A first liquid inlet pipe and a second liquid inlet pipe are arranged at the top of the extraction tower. A uniform box body is fixedly arranged inside the extract collecting tower, and the uniform box body is connected to an air inlet pipe. A filter screen is arranged below the uniform box body. The bottom of the extract collecting tower is connected to the top of the distillation tower through a feed pump; an intermediate extraction method, the waste tobacco is crushed by the crushing tower, and then sent to the extraction tower to mix with calcium hydroxide solution and ethanol, stirred and extracted for 20-60 hours, carbon dioxide gas is introduced into the mixed solution and filtered to obtain an extract, and the extract is fractionated to obtain nicotine and tobacco flavor. This invention can effectively extract nicotine and tobacco flavor intermediates from waste tobacco.

[0004] The existing CBDV intermediate extraction device has the following disadvantages when used:

[0005] 1. During the extraction of CBDV intermediates, the filter box structure is prone to clogging. Due to the diversity of raw materials and the complex chemical reactions during the extraction process, some tiny and sticky impurity particles are easy to adhere to the surface of the filter. Over time, they gradually accumulate and clog the pores of the filter. The outflow rate of the extract is significantly slowed down, causing the liquid level in the extraction tank to rise.

[0006] 2. Existing equipment often lacks an effective waste heat recovery mechanism. The heat is usually directly dissipated into the surrounding environment and is not fully utilized, resulting in a large waste of energy and making the energy consumption of the extraction process remain high. Summary of the invention

[0007] The purpose of the present invention is to target an existing CBDV intermediate extraction device, which has the advantage that a breaking mechanism linked to a rotating shaft is arranged in the extraction tank to solve the problem of easy clogging of the filtering mechanism, thereby ensuring smooth filtration and avoiding the reduced production efficiency, increased labor costs and potential safety hazards caused by clogging; at the same time, by adding a steam recovery structure and a waste heat recovery structure, the recovery and utilization of steam thermal energy and the effective utilization of waste heat in the extraction tank are realized, thereby solving the problems of energy waste and low energy utilization efficiency in the prior art and reducing energy costs.

[0008] The above technical purpose of the present invention is achieved through the following technical solutions: a CBDV intermediate extraction device, comprising an extraction tank, the inner wall of the extraction tank is rotatably connected to a rotating shaft, the surface of the rotating shaft is bolted with a mixing mechanism, the inner wall of the extraction tank is movably connected to a filtering mechanism, the bottom of the rotating shaft is bolted with a breaking mechanism, the inner wall of the extraction tank is provided with a steam pipe, the top of the steam pipe is fixedly connected to a steam recovery structure, the surface of the steam recovery structure is fixedly connected to a waste heat recovery structure, the right side of the steam recovery structure is fixedly connected to a condensation structure, the top of the condensation structure is fixedly connected to a discharge structure, and the surface of the extraction tank is bolted with an electric heating structure.

The filtering mechanism can effectively intercept impurities generated during the extraction process, ensure the purity of the extract, and avoid the adverse effects of impurities on subsequent processes and product quality.

The waste heat recovery structure recycles the heat carried by the steam for reuse, which is used to preheat the materials entering the extraction tank or maintain a suitable temperature in the extraction tank, thereby improving energy utilization and reducing the energy consumption of the entire extraction process. The condensation structure and the emission structure cooperate to ensure that the recovered gas can be discharged safely and environmentally friendly, ensuring the safety and environmental friendliness of the production process.

The knob is used to fix the rotating shaft to ensure the operating stability of the breaking up mechanism. The anti-clogging component can effectively prevent the material from agglomerating and accumulating above the filtering mechanism. The rotating block and the rotating plate continuously disturb the material during the rotation process to break up the agglomerates that may be formed, so that the material can pass through the filtering mechanism evenly, maintaining the smoothness and stability of the extraction process, further optimizing the extraction effect, and reducing the reduction in extraction efficiency and the risk of extraction tank failure due to material blockage.

The filter box provides a stable installation frame for the filter screen and is easy to disassemble and clean. The filter screen can accurately intercept various impurities generated during the extraction process, and can effectively block everything from fine particles to larger insoluble substances, ensuring that the extract entering the subsequent process has a high degree of purity, avoiding impurities from having adverse effects on subsequent refining, purification and other processes, thereby improving the quality of the final product, reducing the wear and corrosion of equipment by impurities, reducing the frequency of maintenance and replacement of extraction tanks, and ensuring the stable operation of the entire extraction production line.

[0021] By adopting the above technical solution, the steam recovery path and flow rate can be flexibly controlled by setting the first valve, the connecting pipe and the second valve. During the extraction process, by opening the first valve and the second valve and then closing the passage in the waste heat recovery structure, the steam in the steam pipe can be effectively introduced into the connecting pipe for recovery treatment, thereby avoiding the random loss of solvent vapor, reducing the waste of raw materials and pollution to the environment, making the steam recovery process more efficient and controllable, and reducing production costs.
