Description

Technical Field

[0001] This utility model relates to the field of rapeseed oil processing technology, and in particular to a rapeseed oil hydration and dephosphorization equipment. Background Technology

[0002] In the edible oil processing industry, hydration dephosphorization of rapeseed oil is one of the key processes in crude oil refining. The principle is based on the hydrophilic nature of impurities such as phospholipids. By adding a certain amount of water or electrolyte solution (such as hydration solution) to the crude oil, the phospholipids absorb water and swell to form micelles, which then separate from the oil, thus removing phosphorus impurities and improving oil quality. The main factors affecting hydration dephosphorization include the amount of water added, temperature, and mixing efficiency. Existing hydration dephosphorization equipment typically includes a hydration container, a stirring device, and a separation structure. However, traditional equipment has the following shortcomings in practical applications:

[0003] Conventional mixing devices often use single-stage mixing blades or fixed spraying structures, which makes it difficult to achieve sufficient mixing of oil and water (or hydrated liquid) at different heights and in different areas. This results in insufficient contact between phospholipids and water, affecting dephosphorization efficiency. Some equipment improves the mixing effect by increasing the complexity of the mixing components, but this can easily cause the mixing structure to shake or be damaged due to centrifugal force when rotating at high speed. Furthermore, due to the lag in the time between material mixing and the addition of water and oil, the subsequent mixing efficiency is still problematic.

[0004] Therefore, there is a need for a rapeseed oil hydration dephosphorization equipment with a reasonable structural design, high mixing efficiency, good separation effect, and stable operation, in order to solve the problems of uneven mixing and structural stability in the existing technology.

[0005] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this utility model, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that this utility model does not have the features of these prior art.

Detailed Implementation

[0021] The following is a detailed explanation with reference to the accompanying drawings.

[0022] Example 1

[0023] This utility model provides a rapeseed oil hydration dephosphorization device, such as... Figure 1 and Figure 2 As shown, the system includes a hydration tank 100. A hydration assembly 200 is housed inside the hydration tank 100. The hydration assembly 200 includes a rotating shaft 201 located at the vertical top of the hydration tank 100 and a drive motor 202 cooperating with the rotating shaft 201. The rotating shaft 201 is connected to the output shaft of the drive motor 202 via a transmission belt 203. A spray pipe 204 is connected to the portion of the rotating shaft 201 that extends into the hydration tank 100 and is located inside the hydration tank 100. The spray pipe 204 has several spray heads 205 arranged at different height levels. Reinforcing ribs 206 are also provided on the spray pipe 204 and are fixedly connected to it. The reinforcing ribs 206 can be used to agitate the fluid. This invention uses a drive motor 202 to drive a rotating shaft 201 via a transmission belt 203, causing the spray pipe 204 connected to the rotating shaft 201 to rotate synchronously. With the help of spray heads 205 at different height levels, water (or hydration liquid) can be sprayed from multiple heights into the rapeseed oil in the hydration tank 100, achieving initial uniform contact between water and oil. The reinforcing ribs 206 disturb the fluid as the spray pipe 204 rotates, further enhancing the mixing effect of oil and water and improving the sufficiency and efficiency of the hydration dephosphorization reaction.

[0024] According to a preferred embodiment, such as Figure 3As shown, at least one reinforcing rib 206 is fixedly connected to the rotating shaft 201 and the spray pipe 204 in a straight line. At least one reinforcing rib 206 is fixedly connected to the spray pipe 204 in a curved line but not connected to the rotating shaft 201. The straight-lined reinforcing rib 206 connects both the rotating shaft 201 and the spray pipe 204, enhancing the connection strength between the spray pipe 204 and the rotating shaft 201, preventing the spray pipe 204 from shaking or being damaged due to centrifugal force during rotation, and improving structural stability. The straight-lined reinforcing rib 206 also serves to connect the spray pipe 204 to the rotating shaft 201 as a fluid channel. The curved-lined reinforcing rib 206 only connects to the spray pipe 204 and not to the rotating shaft 201, resulting in gentler and wider-ranging disturbance to the fluid during rotation, reducing the impact on the already formed fluid mixture, while also ensuring mixing uniformity and balancing structural strength and mixing effect.

[0025] According to a preferred embodiment, the reinforcing rib 206 is fixedly fitted onto the vertical end face of the spray pipe 204 and is higher than the spray pipe 204. The reinforcing rib 206 is fixedly fitted onto the spray pipe 204 in a streamlined curve at different height levels. Because the reinforcing rib 206 is fitted onto the vertical end face of the spray pipe 204 and is higher than the spray pipe 204, it can more directly agitate the fluid during rotation, enhancing the agitation effect. The streamlined curve design at different height levels reduces fluid resistance and lowers driving energy consumption, while ensuring that the fluid at different heights is sufficiently agitated, further improving the uniformity of oil-water mixing. Furthermore, the fitted and fixed method enhances the connection stability between the reinforcing rib 206 and the spray pipe 204.

[0026] According to a preferred embodiment, the spray pipe 204 is spirally extended around the axis of the rotating shaft 201. A plurality of reinforcing ribs 206 are arranged along the spiral extension of the spray pipe 204. The spiral extension of the spray pipe 204 around the axis of the rotating shaft 201 expands the spraying range, allowing water (or hydration liquid) to cover a larger space within the hydration tank 100 during rotation, thus increasing the spray coverage area. The reinforcing ribs 206, arranged in a spiral direction, create a spiral disturbance in the fluid as the spiral spray pipe 204 rotates, promoting the convection mixing of oil and water, further improving mixing efficiency and uniformity, and enhancing the hydration dephosphorization effect.

[0027] According to a preferred embodiment, a water inlet chamber 101 is provided at the vertical end of the rotating shaft 201. The rotating shaft 201 is rotatably connected to the water inlet chamber 101, and the vertical end of the rotating shaft 201 is connected to the interior of the water inlet chamber 101. The rotating shaft 201 is hollow, and the hollow interior of the rotating shaft 201 is connected to the spray pipe 204. The hollow rotating shaft 201 connects the water inlet chamber 101 and the spray pipe 204, realizing stable water supply in the rotating state. It eliminates the need for additional water supply pipelines to rotate synchronously with the spray pipe 204, simplifies the equipment structure, avoids pipeline entanglement problems, ensures the continuity and stability of water (or hydrated liquid) supply, and improves the reliability of equipment operation.

[0028] According to a preferred embodiment, sealing elements are provided at the connection between the rotating shaft 201 and the water inlet chamber 101, and at the connection between the rotating shaft 201 and the hydration tank 100, to prevent fluid leakage. The sealing elements effectively prevent rapeseed oil and water (or hydration liquid) in the hydration tank 100 from leaking from the connection between the rotating shaft 201 and the water inlet chamber 101, and between the rotating shaft 201 and the hydration tank 100. Simultaneously, they prevent water from leaking out of the water inlet chamber 101, ensuring the equipment's airtightness, reducing material loss, maintaining stable internal pressure, preventing environmental pollution or equipment malfunction due to leakage, and improving operational safety.

[0029] According to a preferred embodiment, the vertical end of the hydration tank 100 is further provided with a drive cavity 105 for accommodating the drive motor 202 and the transmission belt 203. A water inlet cavity 101 is located vertically above the drive cavity 105, and a rotating shaft 201 sequentially passes through the hydration tank 100, the drive cavity 105, and the water inlet cavity 101. The drive cavity 105 accommodates the drive motor 202 and the transmission belt 203, which can isolate the motor and transmission belt 203 from the corrosion of oil and water (or hydration liquid) in the hydration tank 100, extending their service life. The water inlet cavity 101 is located above the drive cavity 105, and the rotating shaft 201 sequentially passes through the hydration tank 100, the drive cavity 105, and the water inlet cavity 101, making the equipment structure compact, reducing space occupation, and facilitating the coordinated work of various components, thus improving the equipment integration.

[0030] According to a preferred embodiment, a sedimentation chamber 102 is provided on the vertical bottom surface of the hydration tank 100. The bottom surface of the sedimentation chamber 102 is set as an inclined surface. An oil outlet 103 is provided at the lowest point of the inclined surface of the sedimentation chamber 102. An oil inlet 104 is provided at the vertical upper end of the hydration tank 100. The inclined surface design causes the sediment to gather at the lowest point, which is convenient for cleaning; the oil outlet 103 is located at the lowest point, which facilitates the concentrated discharge of dephosphorized rapeseed oil; the oil inlet 104 is located at the upper end of the hydration tank 100, so that the rapeseed oil enters from the top and forms a counter-current contact with the water (or hydration liquid) sprayed by the spray pipe 204, which improves the mixing effect and enhances the dephosphorization efficiency.

[0031] According to a preferred embodiment, a heating component for heating the interior of the hydration tank 100 is provided on the circumferential side wall of the hydration tank 100. The heating component can regulate the temperature inside the hydration tank 100, so that rapeseed oil and water (or hydration liquid) can undergo a hydration reaction under suitable temperature conditions, promote the coagulation and precipitation of impurities such as phospholipids, improve the dephosphorization effect and efficiency, adapt to the temperature requirements of different processes, and enhance the applicability of the equipment.

[0032] According to a preferred embodiment, a pump is connected to the water inlet chamber 101. A one-way valve is installed between the water inlet chamber 101 and the pump. The pump provides a stable water pressure to the water inlet chamber 101, ensuring the spraying pressure and flow rate of the spray pipe 204, and ensuring that the water (or hydrated liquid) is in full contact with the rapeseed oil; the one-way valve can prevent the water (or hydrated liquid) from flowing back due to pressure fluctuations, ensuring a stable water supply direction, avoiding insufficient water supply or unstable spraying effect caused by backflow, and maintaining the continuity of the hydration and dephosphorization process.
