Description

Technical Field

[0001] This invention belongs to the field of liquid soap preparation technology, specifically relating to an integrated cyclone separation liquid soap preparation device and its usage method. Background Technology

[0002] Hydrocyclone separation technology plays a crucial role in the efficient separation and purification of liquid soap. Its core principle is the rapid separation of multiphase mixtures through centrifugal force. The specific functions are analyzed below: 1) Raw material purification: In the liquid soap production process, hydrocyclones can perform liquid-solid separation on raw materials such as oils and alkali solutions, removing impurities (such as unreacted saponification residue) and ensuring raw material purity. 2) Post-reaction treatment: After the saponification reaction, hydrocyclone separation technology can quickly separate glycerol byproducts and unreacted oils from the product, improving the clarity of the liquid soap. Its conical structure design can extend the material residence time and enhance the separation effect. 3) Energy saving and efficiency advantages: Compared with traditional sedimentation methods, hydrocyclones have a larger processing capacity and smaller footprint, making them suitable for continuous production. However, attention should be paid to the high energy consumption of the feed pump. 4) Environmental applications: In wastewater treatment, this technology can recover suspended solids in saponification wastewater, achieving resource recycling.

[0003] Existing integrated hydrocyclone separation liquid soap preparation devices have shortcomings in use. First, their function is limited and cannot simultaneously meet the requirements of stirring and hydrocyclone separation in the liquid soap preparation process. Second, they cannot promptly scrape off the raw materials adhering to the inner wall of the stirring vessel to ensure their full participation in the reaction and improve the clarity of the liquid soap. Therefore, it is necessary to optimize and improve the existing integrated hydrocyclone separation liquid soap preparation devices. Summary of the Invention

[0004] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and to provide an integrated cyclone separation liquid soap preparation device and its usage method.

[0005] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution:

[0006] This invention provides an integrated liquid soap preparation device with hydrocyclone separation, including a mixing vessel. The top plate of the mixing vessel is equipped with a feed pipe, and the bottom plate of the mixing vessel is equipped with a discharge pipe. The mixing vessel is equipped with a suction component, a hydrocyclone separator, and a scraping component. The suction component can suction the liquid material and supply liquid to the hydrocyclone separator in the later stage of mixing, and supply liquid to the scraping component in the early stage of mixing.

[0007] Furthermore, in the aforementioned integrated liquid soap preparation device for hydrocyclone separation, the suction assembly includes a central vertical pipe, a suction pump, a first pumping pipe, a first opening valve, a second pumping pipe, and a second opening valve. The bottom end of the inner cavity of the central vertical pipe is connected to the output end of the suction pump via a flexible hose. The top two sides of the inner cavity of the central vertical pipe are respectively connected to a first pumping pipe connected to a hydrocyclone separator and a second pumping pipe connected to a scraping assembly. A first opening valve is installed on the first pumping pipe, and a second opening valve is installed on the second pumping pipe.

[0008] Furthermore, in the above-mentioned integrated liquid soap preparation device for hydrocyclone separation, the hydrocyclone separator includes a cylinder, an inlet pipe connected to the first pump pipe is provided on one side of the upper part of the cylinder, an overflow pipe located outside the mixing vessel is provided on the other side of the upper part of the cylinder, and a slag discharge pipe is provided at the bottom end of the cylinder.

[0009] Furthermore, in the aforementioned integrated cyclone separation liquid soap preparation device, the scraping assembly includes a lead screw motor, a lead screw, an annular carrier block, an annular spray pipe, nozzles, an annular scraper, and a liquid guide pipe. The lead screw motor is fixed to the outer wall of the top plate of the mixing vessel by a motor bracket. The output shaft of the lead screw motor is connected to a lead screw that extends into the mixing vessel. An annular carrier block is sleeved on the outer side of the lead screw. An annular spray pipe is embedded in the annular carrier block. Several nozzles are installed circumferentially on the outer side of the annular spray pipe. An annular scraper is installed near both ends on the outer side of the annular spray pipe. A liquid guide pipe for connecting the annular spray pipe and the second pumping pipe passes through the inner side of the annular spray pipe.

[0010] Furthermore, in the above-mentioned integrated liquid soap preparation device for hydrocyclone separation, the annular carrier block is provided with a screw groove that cooperates with the screw and a guide hole that facilitates the passage of the guide rod. The two ends of the guide rod are respectively fixed perpendicularly to the top plate and bottom plate of the mixing vessel.

[0011] Furthermore, in the above-mentioned integrated liquid soap preparation device for hydrocyclone separation, the two annular scrapers, the annular carrier block and the mixing vessel together form an annular scraping zone. The annular scrapers are made of flexible wear-resistant silicone material. When the nozzle sprays high-pressure liquid into the annular scraping zone, it can drive the annular scrapers on both sides to swing back and forth.

[0012] Furthermore, the aforementioned integrated liquid soap preparation device for hydrocyclone separation also includes a controller, which is connected to a suction pump, a first opening valve, a second opening valve, and a lead screw motor.

[0013] Furthermore, the above-mentioned integrated hydrocyclone separation liquid soap preparation device is used in the following manner:

[0014] S1. Add liquid and solid materials for preparing liquid soap into the mixing vessel through the feed pipe;

[0015] S2. Start the suction pump of the suction assembly. The suction pump draws the liquid material and sends it into the annular spray pipe of the scraping assembly through the central vertical pipe and the second pumping pipe. The annular spray pipe sprays high-pressure liquid into the annular scraping area through the nozzle. The high-pressure liquid drives the annular scrapers on both sides to swing back and forth, realizing the circulation and mixing of the liquid material.

[0016] S3. Start the suction pump of the suction assembly. The suction pump draws the liquid material and sends it into the hydrocyclone separator through the central vertical pipe and the first pumping pipe. The hydrocyclone separator separates the glycerol byproduct and unreacted oil in the product. The liquid soap is transferred outward through the overflow pipe of the hydrocyclone separator.

[0017] The beneficial effects of this invention are:

[0018] 1. High-efficiency integrated design for mixing and separation

[0019] Seamless integration of mixing and separation processes: The device achieves automatic switching between supplying liquid to the scraping component in the early stage of mixing and supplying liquid to the hydrocyclone separator in the later stage through the suction components (central vertical pipe, dual pump pipes and valves), which simplifies the cumbersome steps of transferring materials in traditional processes and improves efficiency.

[0020] Dynamic scraping enhances mixing: The annular spray pipe and flexible scraper of the scraping component oscillate back and forth under high-pressure liquid jet, which not only promotes material circulation and mixing, but also prevents scale buildup on the reactor wall, making it especially suitable for the uniform dispersion of high-viscosity liquid soap raw materials.

[0021] 2. Precise application of cyclone separation technology

[0022] Highly efficient separation of glycerol and unreacted oils: The hydrocyclone separator utilizes the principle of centrifugal force and, through the synergistic action of the feed pipe, overflow pipe, and slag discharge pipe, quickly separates components with different densities (such as glycerol byproducts and oils). It has high separation efficiency and does not require a filter, reducing the risk of clogging.

[0023] Compact structure and automated control: The hydrocyclone separator is integrated into the mixing vessel, saving space; together with the controller, the valve opening and pump speed are adjusted to achieve precise control of the separation process and adapt to different working conditions.

[0024] 3. Innovative scraping and spraying synergy mechanism

[0025] Flexible scraper and high-pressure spray linkage: The ring scraper is made of wear-resistant silicone material and swings under the high pressure liquid of the nozzle, which has the functions of scraping the wall and stirring. It effectively solves the problem of adhesion of high viscosity materials and enhances the uniformity of mixing.

[0026] Modular design facilitates maintenance: The screw motor and guide rod structure of the scraper assembly ensures stable lifting and lowering of the annular block, and the detachable design of the spray pipe and liquid guide pipe facilitates cleaning and maintenance.

[0027] 4. Safety and process adaptability

[0028] The closed system reduces the risk of contamination: the mixing vessel and the cyclone separator form a closed environment, reducing external contamination and making it suitable for the production of food-grade liquid soap.

[0029] Flexible response to different process stages: By adjusting the suction pump and valves through the controller, the mixing and separation modes can be flexibly switched to adapt to the needs of small-batch or continuous production.

[0030] 5. Energy-saving and environmental protection advantages

[0031] Reduced energy consumption and waste generation: Cyclone separation technology eliminates the need for additional filter media, thus reducing energy consumption; the impurity discharge pipe and slag discharge pipe handle solid impurities and separated waste materials respectively, reducing waste liquid treatment costs.

[0032] Resource recycling: The separated glycerol byproducts can be recycled through subsequent processes, improving resource utilization and conforming to the concept of green chemical industry.

[0033] Of course, any product implementing this invention does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] like Figures 1-6 As shown, this embodiment provides an integrated liquid soap preparation device with hydrocyclone separation, including a mixing vessel 1. A feed pipe 2 is installed on the top plate of the mixing vessel 1, and a waste discharge pipe 3 is installed on the bottom plate of the mixing vessel 1. The mixing vessel 1 is equipped with a suction assembly 4, a hydrocyclone separator 5, and a scraping assembly 6. The suction assembly 4 can suction the liquid material and can supply liquid to the hydrocyclone separator 5 in the later stage of mixing, and supply liquid to the scraping assembly 6 in the early stage of mixing.

[0045] In this embodiment, the suction assembly 4 includes a central vertical pipe 401, a suction pump 402, a first pumping pipe 403, a first opening valve 404, a second pumping pipe 405, and a second opening valve 406. The bottom end of the inner cavity of the central vertical pipe 401 is connected to the output end of the suction pump 402 via a flexible hose. The top two sides of the inner cavity of the central vertical pipe 401 are respectively connected to the first pumping pipe 403, which is connected to the cyclone separator 5, and the second pumping pipe 405, which is connected to the scraper assembly 6. The first opening valve 404 is installed on the first pumping pipe 403, and the second opening valve 406 is installed on the second pumping pipe 405.

[0046] In this embodiment, the cyclone separator 5 includes a cylinder 501. The upper side of the cylinder 501 is provided with an inlet pipe 502 connected to the first pumping pipe 403, the other upper side of the cylinder 501 is provided with an overflow pipe 504 located outside the mixing vessel 1, and the bottom end of the cylinder 501 is provided with a slag discharge pipe 503.

[0047] In this embodiment, the scraping assembly 6 includes a lead screw motor 601, a lead screw 602, an annular carrier block 603, an annular spray pipe 604, nozzles 605, an annular scraper 606, and a liquid guide pipe 607. The lead screw motor 601 is fixed to the outer wall of the top plate of the mixing vessel 1 by a motor bracket. The output shaft of the lead screw motor 601 is connected to the lead screw 602, which extends into the mixing vessel 1. The annular carrier block 603 is sleeved on the outer side of the lead screw 602. The annular spray pipe 604 is embedded in the annular carrier block 603. Several nozzles 605 are installed circumferentially on the outer side of the annular spray pipe 604. The annular scraper 606 is installed near both ends on the outer side of the annular spray pipe 604. A liquid guide pipe for connecting the annular spray pipe 604 and the second pumping pipe 405 passes through the inner side of the annular spray pipe 604.

[0048] In this embodiment, the annular carrier block 603 is provided with a screw groove 608 that cooperates with the screw 602 and a guide hole 609 that facilitates the passage of the guide rod. The two ends of the guide rod are respectively fixed perpendicularly to the top plate and the bottom plate of the mixing vessel 1.

[0049] In this embodiment, two annular scrapers 606, annular carrier block 603 and mixing vessel 1 together form an annular scraping area. The annular scrapers 606 are made of flexible wear-resistant silicone material. When the nozzle 605 sprays high-pressure liquid into the annular scraping area, it can drive the annular scrapers 606 on both sides to swing back and forth.

[0050] In this embodiment, a controller is also included, which is connected to the suction pump 402, the first opening valve 404, the second opening valve 406 and the lead screw motor 601 respectively.

[0051] In this embodiment, the method of using the integrated hydrocyclone separation liquid soap preparation device includes the following steps:

[0052] S1. Add liquid and solid materials for preparing liquid soap to mixing vessel 1 through feed pipe 2;

[0053] S2. Start the suction pump 402 of the suction assembly 4. The suction pump 402 draws the liquid material and sends it into the annular spray pipe 604 of the scraping assembly 6 through the central vertical pipe 401 and the second pumping pipe 405. The annular spray pipe 604 sprays high-pressure liquid into the annular scraping area through the nozzle 605. The high-pressure liquid drives the annular scrapers 606 on both sides to swing back and forth, realizing the circulation and mixing of the liquid material.

[0054] S3. Start the suction pump 402 of the suction assembly 4. The suction pump 402 draws the liquid material and sends it into the hydrocyclone 5 through the central vertical pipe 401 and the first pumping pipe 403. The hydrocyclone 5 separates the glycerol byproduct and unreacted oil in the product. The liquid soap is transferred outward through the overflow pipe 502 of the hydrocyclone 5.

[0055] One specific application of this embodiment is as follows: the device automatically switches between supplying liquid to the scraping assembly in the early stage of mixing and supplying liquid to the hydrocyclone separator in the later stage through a suction component (central vertical pipe, dual pumping pipes, and valves). This simplifies the cumbersome steps of transferring materials in traditional processes and improves efficiency. The annular spray pipe and flexible scraper of the scraping assembly oscillate back and forth under high-pressure liquid jets, which not only promotes material circulation and mixing but also prevents scaling on the vessel wall, making it particularly suitable for the uniform dispersion of high-viscosity liquid soap raw materials. The hydrocyclone separator utilizes the principle of centrifugal force and, through the synergistic action of the feed pipe, overflow pipe, and slag discharge pipe, quickly separates components with different densities (such as glycerol byproducts and oils). It has high separation efficiency and eliminates the need for filters, reducing the risk of clogging. The hydrocyclone separator is integrated into the mixing vessel, saving space; with the controller, the valve opening and pump speed can be adjusted to achieve precise control of the separation process and adapt to different working conditions. The annular scraper is made of wear-resistant silicone material and oscillates under the high-pressure liquid drive of the nozzle, combining scraping and stirring functions to effectively solve the adhesion problem of high-viscosity materials and enhance mixing uniformity. The screw motor and guide rod structure of the scraper assembly ensure stable lifting and lowering of the annular carrier block, while the detachable design of the spray pipe and liquid guide pipe facilitates cleaning and maintenance. The mixing vessel and hydrocyclone separator form a closed environment, reducing external contamination and making it suitable for food-grade liquid soap production. The controller allows for flexible switching between mixing and separation modes by adjusting the suction pump and valves, adapting to small-batch or continuous production needs. Hydrocyclone separation technology eliminates the need for additional filter media, reducing energy consumption; the impurity discharge pipe and slag discharge pipe separately handle solid impurities and separation waste, reducing wastewater treatment costs. The separated glycerol byproduct can be recovered through subsequent processes, improving resource utilization and aligning with green chemical engineering principles.
