Description

Technical Field

[0001] This utility model relates to the field of rapeseed oil processing technology, and in particular to a raw material metering device for rapeseed oil production that is easy to adjust. Background Technology

[0002] In the oil processing industry, accurate metering of raw oil is a core element in ensuring the stability of rapeseed oil quality and production efficiency. Traditional rapeseed oil metering devices mainly rely on the following typical technical solutions, which have inherent drawbacks:

[0003] 1. Limitations of the application of weighing-based quantitative methods

[0004] When oil is injected into the weighing container through a pipeline, the fluid momentum generates an impact force. According to the momentum theorem, this impact force fluctuation causes oscillations in the load cell output value. Especially at high flow rates, the dynamic error severely affects measurement accuracy. Changes in ambient air humidity can easily cause condensation on the load cell surface, resulting in zero-point drift. Weighing control relies on a closed-loop "detection-comparison-adjustment" process. Its sampling period leads to high overshoot during small-range quantitative measurements, failing to meet the metrological accuracy requirements of precise proportioning.

[0005] 2. Inherent defects of flow meter quantitative technology

[0006] Flow meters based on throttling or velocity principles face the following challenges in rapeseed oil metering: the instrument coefficient of turbine flow meters is inversely proportional to fluid viscosity. A straight pipe section of 10D upstream and 5D downstream (D being the pipe diameter) is required to stabilize the flow, but space is limited in actual production lines, and vortex flows caused by bends and valves increase measurement uncertainty by 2-3 times. Oily substances form scale on the flow meter's surface, altering the flow cross-sectional area and requiring periodic disassembly and cleaning, affecting production continuity.

[0007] With consumers demanding higher quality rapeseed oil, the rapeseed oil industry shifting towards "high value-added products (such as cold-pressed oil and functional oils)," and the development of large-scale and automated production, traditional quantitative measuring devices can no longer meet the needs of modern rapeseed oil production. This is especially true in the production of high-end pressed rapeseed oil and low-erucic acid rapeseed oil, where high precision in raw material proportioning is required, along with strict hygiene standards. Therefore, developing a high-precision, easily adjustable, and highly reliable raw material quantitative device for rapeseed oil production is of significant practical importance.

[0008] 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

[0027] The following is a detailed explanation with reference to the accompanying drawings.

[0028] Example 1

[0029] This utility model provides a raw material metering device for rapeseed oil production that is easy to adjust, such as... Figure 1 and Figure 2 As shown, the device includes a support body 100. An oil inlet tank 101 and an oil outlet tank 102 are mounted on the support body 100. The oil inlet tank 101 and the oil outlet tank 102 are arranged adjacently but not connected. A metering tank 103, connecting the oil inlet tank 101 and the oil outlet tank 102, is arranged vertically below them. A metering mechanism 300 is installed inside the metering tank 103. The metering mechanism 300 includes a sealing element 301 and a sealing pusher 302. The sealing pusher 302 penetrates the vertical bottom surface of the metering tank 103 and is connected to a drive assembly 400 mounted on the support body 100. The raw material metering device for rapeseed oil production provided by this utility model achieves precise metering control through a multi-component collaborative design. The oil inlet tank 101 and oil outlet tank 102, which are arranged side by side on the support body 100, adopt an adjacent but non-connected structure. They are completely independent through physical separation, and are connected only through the metering tank 103 to achieve fluid communication, forming a three-level processing architecture of "top inlet - middle stop - bottom outlet". The metering mechanism 300 inside the metering tank 103 adopts a coaxially designed seal 301 and a sealing pusher 302. The outer edge of the seal 301 forms an annular sealing surface with the inner wall of the metering tank. The horizontal sliding divides the tank into upper and lower cavities. With the vertical axial movement of the sealing pusher 302, the precise adjustment of the metering volume is achieved.

[0030] The coaxial design and high-precision sealing structure of the metering mechanism 300 in this invention effectively prevent oil leakage and ensure the accuracy of the metering process. The precise control of the gear and rack meshing clearance through the modified gear design ensures stable metering accuracy, meeting the high-precision requirements for raw material metering in rapeseed oil production.

[0031] According to a preferred embodiment, such as Figure 3 As shown, the sealing pusher 302 is slidably connected to the metering tank 103. The sealing member 301 is disposed vertically above the sealing pusher 302. The outer edge of the sealing member 301 is in sealing contact with the metering tank 103 to separate the metering tank 103 in the horizontal direction. Preferably, the outer edge of the sealing member 301 can be provided with several layers of sealing rings in the circumferential direction to ensure that the extracted fluid does not leak.

[0032] According to a preferred embodiment, the sealing element 301 and the sealing pusher 302 are coaxially arranged with the metering tank 103. The sealing pusher 302 moves axially in the vertical direction to push the sealing element 301. The drive assembly 400 uses a servo motor as its power source. When the drive assembly 400 drives the sealing pusher 302 upward, the volume of the upper chamber of the metering tank 103 expands, the oil inlet check valve opens, and the raw material oil fills the upper chamber under gravity; when moving downward, the sealing element 301 pushes the oil to compress, the oil outlet check valve opens, and a constant volume output is achieved. The entire metering process is controlled by the precise transmission of the gear 401 and rack 303 to control the vertical stroke of the sealing element 301. Combined with real-time calibration through the observation window, high-precision control of oil volume can be achieved within the metering range. Compared with traditional volumetric metering devices, this improves oil control efficiency and reduces energy consumption, effectively solving the technical problems of insufficient metering accuracy and inconvenient adjustment in existing equipment. It is particularly suitable for the raw material proportioning of large-scale rapeseed oil production lines.

[0033] According to a preferred embodiment, the vertically downward end of the sealing pusher 302 is configured as a rack 303 with a plurality of teeth. The drive assembly 400 is mounted on the support body 100 with its output shaft perpendicular to the sealing pusher 302. The output shaft of the drive assembly 400 is provided with a gear 401 that meshes with the rack 303, and the gear 401 and rack 303 form a gear pair. The rack 303 at the lower end of the sealing pusher 302 and the gear 401 of the drive assembly 400 form a gear pair. This vertical transmission structure drives the gear to rotate via a motor, converting circular motion into linear motion of the rack. Compared with traditional screw drives, it has higher transmission efficiency and smoother motion, and the meshing clearance of the gear and rack can be precisely controlled through a modified gear design to ensure quantitative accuracy.

[0034] According to a preferred embodiment, the system further includes a valve assembly 200, with the inlet tank 101 and the metering tank 103 connected via at least one valve assembly 200. The outlet tank 102 and the metering tank 103 are also connected via at least one valve assembly 200. The valve assembly 200 is configured as a check valve. This dual check valve configuration effectively prevents oil backflow and interference, ensuring the stability and accuracy of the metering process.

[0035] According to a preferred embodiment, at least one valve assembly 200 is configured to prevent fluid in the metering tank 103 from flowing back into the inlet tank 101. At least one valve assembly 200 is also configured to prevent fluid in the outlet tank 102 from flowing into the metering tank 103. The valve assembly 200 employs a dual check valve configuration. The check valve between the inlet tank 101 and the metering tank 103 is configured with an upward inlet and downward outlet flow direction to prevent backflow of oil from the metering tank 103 and contamination of the raw materials. The check valve between the outlet tank 102 and the metering tank 103 is configured with a downward inlet and upward outlet flow direction to avoid interference from the outlet pipeline pressure on the metering process.

[0036] According to a preferred embodiment, such as Figure 4 and Figure 5 The diagram illustrates a preferred embodiment where the valve assembly 200 is located at the outlet tank 102. Preferably, the valve assembly 200 includes an inlet valve 201, an outlet valve 202, a valve seat 203, and a valve core 204. The inlet valve 201 is connected to the tank where fluid enters, and the outlet valve 202 is connected to the tank where fluid exits. Thus, the valve assembly 200 can control the unidirectional flow of fluid, preventing backflow. Figure 6 As shown, this is a preferred embodiment in which the valve assembly 200 is located at the oil inlet tank 101.

[0037] According to a preferred embodiment, the valve seat 203 and the valve core 204 are disposed in the channel between the inlet valve 201 and the outlet valve 202. A step is provided in the channel between the inlet valve 201 and the outlet valve 202 to engage the valve core 203. An elastic element 205 is provided between the valve seat 203 and the valve core 204. Specifically, the valve core 204 is pressed against the step by the elastic element 205, thereby achieving a reliable seal. The oil inlet 104 at the top of the oil tank 101 and the oil outlet 105 at the bottom of the oil tank 102 adopt a quick-connect flange structure, which, together with an O-ring seal, enables quick assembly and disassembly, meeting the rapid changeover requirements of the production line.

[0038] According to a preferred embodiment, an oil inlet 104 is connected vertically upward to the oil inlet tank 101, and an oil outlet 105 is connected vertically downward to the oil outlet tank 102. The oil inlet 104 is used to add fluid into the oil inlet tank 101. The oil outlet 105 is used to discharge the fluid extracted after metering to the oil outlet tank 102 to complete the collection process. It should be noted that the fluid in this invention refers to raw oil or other fluid substances used in the rapeseed oil production process, and can also refer to the metering process of rapeseed oil itself.

[0039] According to a preferred embodiment, the metering chamber 103 is provided with an observation window on its circumference for observing the fluid volume inside the metering chamber 103. The observation window is made of oil-resistant tempered glass, and the glass surface is treated with an anti-fog coating to ensure clear observation. A scale is provided on the outside of the observation window. The observation window enables visual monitoring of the fluid volume inside the metering chamber, allowing operators to observe the metering process in real time and perform precise calibration using the scale, further improving the accuracy of metering.
