Technical Field
[0001] This utility model relates to the field of rapeseed oil processing technology, and in particular to a rapeseed cleaning device for easy cleaning in rapeseed oil production. Background Technology
[0002] In rapeseed oil production, rapeseed washing is one of the key pretreatment steps. Existing rapeseed washing equipment often uses agitator blades or vibrating structures to disperse the accumulated rapeseed, but these structures have significant drawbacks: Firstly, the rotation speed and angle of traditional agitator blades are fixed, making it difficult to adapt to rapeseed with different moisture contents or particle sizes, easily leading to uneven dispersion or over-mixing that damages the rapeseed; secondly, although vibrating dispersion devices can initially disperse the rapeseed, the noise generated during vibration is relatively large, and long-term high-frequency vibration can easily cause equipment parts to loosen, increasing maintenance costs.
[0003] Existing technologies also include washing rapeseed with water. However, while traditional washing devices do not suffer from the aforementioned problems, they have structural flaws. For example, they often use a single water flow or simple agitation, which is insufficient to remove impurities such as mud and debris from the gaps between the rapeseed grains. This is especially true for oil stains or clumps of impurities attached to the rapeseed surface, resulting in poor cleaning and insufficient cleanliness of the raw materials for subsequent processing, thus affecting the quality of rapeseed oil. Most washing devices use a single-use water flow cleaning mode, discharging the cleaning solution directly after use without a circulating filtration system. This not only increases production costs but also fails to meet environmental and energy conservation requirements. While some devices have a circulating structure, they lack an effective impurity filtration mechanism, making the circulating water easily contaminated and affecting subsequent cleaning results. Existing devices typically only intercept some impurities through simple filtration, unable to classify impurities of different densities (such as mud, sand, and leaf debris), and the deposited impurities easily clog pipes or filter components. Furthermore, the cleaning process often requires manual disassembly of the main components, which is cumbersome, time-consuming, and labor-intensive, reducing production efficiency.
[0004] In summary, existing rapeseed washing devices have significant shortcomings in terms of washing efficiency, water resource utilization, impurity treatment, and ease of maintenance. A washing device with optimized structure, easy cleaning, and high efficiency and energy saving is needed to solve these problems.

Detailed Implementation
[0024] The following is a detailed explanation with reference to the accompanying drawings.
[0025] Example 1
[0026] This utility model provides a rapeseed cleaning device for easy cleaning in rapeseed oil production, such as... Figure 1 and Figure 2As shown, the invention includes a main body 100. A cleaning assembly 200 is disposed inside the main body 100. The cleaning assembly 200 is hollow, and a cleaning component 201 is disposed through it. The cleaning component 201 is rotatably disposed within the main body 100 and passes through both the cleaning assembly 200 and the main body 100 along the axis of the cleaning assembly 200 to connect to a drive assembly 202. A water outlet 101 is located at the vertical upper end of the main body 100 above the cleaning assembly 200. A water inlet 102 is located at the vertical lower end of the main body 100 above the cleaning assembly 200. A pump 103 is disposed between the water outlet 101 and the water inlet 102. This invention forms a power-driven cleaning structure by providing a rotatable cleaning component 201 inside the main body 100, which passes through the cleaning assembly 200 and connects to the drive assembly 202. When the drive component 202 rotates the cleaning component 201, it mechanically stirs and cleans the rapeseed inside the cleaning component 200. Combined with the water circulation system consisting of the outlet 101, inlet 102, and pump 103, it achieves directional circulation of the cleaning liquid. This structural design ensures the continuity of the cleaning process and significantly improves the cleaning efficiency of the rapeseed through the dual effects of mechanical rotation and water rinsing, while avoiding the problem of incomplete cleaning by unidirectional water flow in traditional cleaning devices. The water circulation design of this invention allows for the discharge of less dense leaves or residue from the rapeseed inside the cleaning component 200 from the outlet 101 into the return water tank 104, while impurities are filtered out by the filter screen 105. The denser mud and sand in the rapeseed inside the cleaning component 200 fall into the cleaning chamber 106, thus achieving differentiated treatment of impurities. Traditional impurity removal devices can only filter out one type of impurity.
[0027] According to a preferred embodiment, such as Figure 3 As shown, the outlet 101 and inlet 102 are connected to the return water tank 104 adjacent to the main body 100. The outlet 101 is located at the vertical end of the return water tank 104. The inlet 102 is located at the vertical lower end of the return water tank 104. Figure 6As shown, a filter screen 105 is installed inside the return water tank 104, between the outlet 101 and the inlet 102. Preferably, the return water tank is also equipped with a switch cover to facilitate cleaning impurities from the filter screen 105. Connecting the outlet 101 and the inlet 102 to the return water tank 104 and installing the filter screen 105 within it constructs a cleaning fluid circulation filtration system. The layout of the outlet 101 located at the upper end of the return water tank and the inlet 102 located at the lower end forms an upward water flow path, allowing the cleaning fluid carrying impurities to pass through the filter screen 105 in the return water tank for impurity interception. The filter screen 105 can effectively intercept lighter impurities in the cleaning fluid, such as rapeseed fragments and leaf debris. This design not only reduces water waste and lowers production costs but also avoids the risk of impurities clogging the pump 103 and cleaning components 200 during circulation, ensuring the long-term stable operation of the entire cleaning system.
[0028] According to a preferred embodiment, a check valve is provided at the connection between the inlet 102 and the return water tank 104. The check valve is designed to prevent the cleaning water inside the main body 100 from flowing back into the return water tank 104. This design, which prevents the cleaning water inside the main body 100 from flowing back into the return water tank 104, establishes a one-way flow protection mechanism. When the pump 103 stops working, the check valve prevents the cleaning fluid inside the main body 100 from flowing back into the return water tank, ensuring that the cleaning fluid always circulates in a one-way flow: "main body 100 cleaning → return water tank → main body re-cleaning," maintaining the cleanliness of the cleaning fluid, indirectly improving the cleaning quality of the rapeseed, and preventing damage to the pump impeller due to reverse rotation caused by backflow.
[0029] According to a preferred embodiment, such as Figure 4 and Figure 5 As shown, the cleaning component 201 extends radially toward the cleaning assembly 200, and a cleaning brush 203 is provided at one end of the cleaning component 201 near the inner wall of the cleaning assembly 200. The length of the cleaning brush 203 is set so as to be close to the inner wall of the cleaning assembly 200. The radial extension of the cleaning component 201 and the cleaning brush 203 at its end close to the inner wall of the cleaning assembly 200 form an inner wall-fitting cleaning structure. When the cleaning component 201 rotates, the cleaning brush 203 can continuously wipe the inner wall of the cleaning assembly, effectively removing stains attached to the wall surface, such as residual rapeseed oil stains, mud clumps, etc. The cleaning brush 203 can also scrub rapeseed. The design of the cleaning brush 203 being close to the inner wall ensures thorough cleaning without dead angles, avoiding the problem of traditional cleaning devices affecting the subsequent cleaning effect due to the accumulation of dirt on the inner wall. At the same time, it reduces the frequency of manual disassembly for cleaning the inner wall, reduces equipment maintenance costs, and improves the automated cleaning capability of the device.
[0030] According to a preferred embodiment, a plurality of cleaning holes 204 are provided through the side of the cleaning component 201. These cleaning holes 204 create a rapeseed flow channel. When the cleaning component 201 rotates, the rapeseed flows through the cleaning holes 204, agitating the accumulated rapeseed and improving its cleanliness. Combined with the mechanical friction of the cleaning brush, this achieves a "rinsing + friction" composite cleaning of the rapeseed. This design can penetrate deep into the rapeseed pile, removing tiny impurities hidden within, solving the problem that traditional single mechanical stirring or water rinsing is insufficient for handling fine impurities. This significantly improves the cleanliness of the rapeseed, providing high-quality raw materials for subsequent processing steps.
[0031] According to a preferred embodiment, the washing assembly 200 has an opening 205 at its vertical end. An inclined plate 206 is connected to the opening 205. A plurality of filter holes 207 are provided at the vertical lower end of the washing assembly 200. The upper opening 205 of the washing assembly 200 is connected to the inclined plate 206, and the lower end has filter holes 207, forming an integrated structure of "feeding-washing-solid-liquid separation". The inclined plate 206 facilitates the smooth flow of rapeseed from the feed inlet into the washing assembly 200, avoiding spillage during manual pouring and preventing rapeseed from being swept out of the washing assembly 200 when the washing component 201 rotates. Furthermore, the inclined plate 206 can also block the flow direction of water, allowing it to flow only through the filter holes 207 on the washing assembly 200, improving the washing efficiency of the rapeseed. The lower filter holes 207 are also used to discharge heavier impurities such as mud and sand, while retaining particles such as rapeseed, achieving preliminary impurity separation. The pore size of the filter holes 207 is smaller than the size of the rapeseed. Therefore, this design optimizes the feeding process and improves operational convenience. At the same time, the aperture design of the filter hole 207 can be adjusted according to the size of the rapeseed particles to ensure that rapeseed is not lost while removing impurities, thus ensuring the integrity of the material during the washing process.
[0032] According to a preferred embodiment, a cleaning chamber 106 for accommodating impurities that have passed through a plurality of filter holes 207 is provided at the vertically bottom end of the main body 100. The cleaning chamber 106 is arranged in a direction that is vertically downward relative to the plurality of filter holes 207. The cleaning chamber 106, which is provided at the bottom end of the main body 100 in a gradient manner, is located directly below the filter holes 207, forming an impurity sedimentation and collection structure. The gradient design allows impurities with higher density (such as silt, metal particles, etc.) to naturally settle to the bottom of the cleaning chamber 106 under the action of gravity, avoiding the problem of impurities circulating and clogging the filter holes 207 within the main body, and also preventing these higher density impurities from clogging the water inlet 102. The gradient structure facilitates the centralized collection of impurities, providing convenience for subsequent impurity treatment (such as sorting and recycling, environmentally friendly discharge), and improving the environmental performance of the device.
[0033] According to a preferred embodiment, a debris outlet 107 connected to the cleaning chamber 106 is provided vertically downwards on the main body 100. The debris outlet 107 directly connects to the cleaning chamber 106, creating a rapid debris discharge channel. When debris needs to be cleaned, simply opening the debris outlet 107 allows the precipitated debris in the cleaning chamber to be discharged all at once, without disassembling the main body 100, significantly shortening cleaning time and improving equipment maintenance efficiency. This design avoids the tedious operation of manually digging deep into the main body to remove debris, reducing the labor intensity of operators and minimizing equipment wear caused by frequent disassembly, thus extending the service life of the device.
[0034] According to a preferred embodiment, a water inlet 108 is provided on the side of the main body 100, located vertically above the cleaning assembly 200. A water pump is connected to the water inlet 108. The water inlet 108 on the side of the main body, located above the cleaning assembly and connected to a water pump, forms a high-pressure water replenishment cleaning structure. Water flows into the cleaning assembly 200 from above, forming convection with the circulating water below, enhancing the impact cleaning effect on the rapeseed. The position design of the water inlet 108 ensures that the replenished water can be evenly distributed within the cleaning assembly, avoiding problems of excessive or insufficient water volume in certain areas, making the entire cleaning process more flexible and controllable, and adapting to production needs with different impurity contents and cleaning precision.
[0035] According to a preferred embodiment, the main body 100 also includes a cover 109 located at the vertical upper end of the main body 100. The cover 109 is snap-fitted to the main body 100. The cover 109 at the upper end of the main body adopts a snap-fit connection, creating a convenient disassembly and maintenance structure. Operators can also put in and take out the washed rapeseed through the cover 109. Compared with traditional bolt connections, the snap-fit connection has the advantages of quick disassembly and convenient installation. Operators can complete the opening and closing of the cover in a short time, facilitating the inspection, maintenance, and deep cleaning of the internal components of the cleaning assembly. This design solves the problem of cleaning dead corners caused by inconvenient maintenance in traditional devices, ensuring the maintainability of each component inside the device. At the same time, the sealing structure of the snap-fit effectively prevents liquid splashing during the cleaning process, ensuring a clean and safe operating environment.
