Description

Technical Field

[0001] This utility model relates to the field of grain and oil production technology, and in particular to a grain and oil purification and extraction device. Background Technology

[0002] Grain and oil purification and extraction equipment is a specialized device used to remove impurities and separate effective components during grain and oil processing. It mainly falls into two technical categories: physical purification and chemical extraction. Grain and oil pressing uses physical pressure to directly separate oil from oilseeds. The entire process involves no chemical additives, ensuring product safety, hygiene, and no pollution, while preserving natural nutrients.

[0003] Chinese Patent No. CN221275713U discloses an intelligent purification and extraction device for grains and oils. The device includes a feeding box with an inlet and an outlet. A guide pipe connects to the outlet, and an oil storage tank is connected to the end of the guide pipe furthest from the outlet. The oil storage tank is at a lower level than the feeding box. A first valve and a second valve are respectively installed at the ends of the guide pipes on the feeding box and oil storage tank sides. A filter structure is installed inside the guide pipe between the first and second valves. A slag discharge pipe connects to the guide pipe between the first valve and the filter structure, and a detachable sealing cap is installed at the outlet of the slag discharge pipe. An air pump connects to the guide pipe between the second valve and the filter structure, and a fourth valve is installed between the air pump and the guide pipe. This invention achieves pneumatic flushing of the filter structure, removing impurities, and has the advantages of simple structure and good sealing performance.

[0004] In existing grain and oil purification and extraction devices, after the grain and oil are purified, they are transported to the oil storage tank through a guide pipe. After the oil reaches a certain level, the purified and extracted grain and oil are discharged through the oil drain pipe and valve. However, after the grain and oil are discharged, residual grain and oil adheres to the inner wall of the oil storage tank. If this residual oil is not discharged, it can easily remain on the inner wall, increasing the risk of biological contamination, affecting the device's ability to purify and extract new oil, and reducing the functionality of the purification and extraction device.

[0016] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0017] Example 1 like Figure 1 - Figure 3 As shown, the present invention proposes a grain and oil purification and extraction device, comprising: a base plate 1, a feeding box 2, an oil storage tank 3, an extrusion assembly a4, an extrusion assembly b5, an oil discharge pipe 6, a valve a7, a conveying pipe 8, a valve b9, a guide pipe 10, a filter pipe 11, an air conveying pipe 12, an air pump 13, a connecting pipe 14, a water pipe 15, a sewage discharge pipe 16, an oil guide pipe 17, and an oil pump 18; the feeding box 2 is connected to the base plate 1; the oil storage tank 3 is connected to the base plate 1; the extrusion assembly a4 is connected to the base plate 1; and the oil discharge assembly b5 is connected to the oil discharge assembly b5. On the oil storage tank 3; the extrusion assembly a4 includes a mounting cover 401, a mounting frame 402, a cylinder 403, a drive rod 404, an extrusion plate 405, and connecting parts; the mounting cover 401 is connected to the oil storage tank 3, the mounting frame 402 is connected to the mounting cover 401, the cylinder 403 is connected to the mounting frame 402, the drive end of the cylinder 403 is connected to the drive rod 404, and the drive rod 404 is connected to the extrusion plate 405; the extrusion assembly b5 is connected to the feeding box 2 and has the same structure as the extrusion assembly a4. The extrusion assembly a4 removes residual grain and oil from the oil storage tank 3, and the extrusion assembly b5 discharges residual grain and oil from the feeding box 2, facilitating the secondary use of the grain and oil purification and extraction device, improving the efficiency of grain and oil purification and extraction, and increasing grain and oil production efficiency.

[0018] Further explanation: the connectors include sealing sleeve a406, sealing sleeve b407, and liquid level sensor 408; sealing sleeve a406 is connected to the upper surface of mounting cover 401, and sealing sleeve b407 is connected to the inner surface of mounting cover 401; liquid level sensor 408 is connected below extrusion plate 405. The sealing sleeves a406 and b407 facilitate improved sealing of mounting cover 401, preventing interference with grain and oil purification and extraction due to the connection between mounting cover 401 and drive rod 404, and improving the ease of connection and use of the components of the grain and oil purification and extraction device.

[0019] Example 2 like Figure 1 As shown, the present invention proposes a grain and oil purification and extraction device. Based on the above embodiments, this embodiment also details the specific components of the feeding box 2 and the oil storage box 3, as well as their cooperation method.

[0020] Further explanation: The oil storage tank 3 is connected to a drain pipe 6 below, which is connected to valve a7; the feeding box 2 is connected to a conveying pipe 8 below, which is connected to valve b9, which is connected to a guide pipe 10, which is connected to a filter pipe 11, which is connected to an air supply pipe 12, which is connected to an air pump 13. The air pump 13 and the feeding box 2 are connected to the base plate 1 via a bracket; the inner wall of the filter pipe 11 is sequentially connected to three filter screens, which is connected to a connecting pipe 14 and a water pipe 15; the guide pipe 10 is connected to a drain pipe 16; the feeding box 2 is connected to an oil guide pipe 17 above, which is connected to an oil pump 18. The oil to be purified and extracted is pumped by oil pump 18 into oil guide pipe 17. The oil outlet of oil guide pipe 17 is connected to the top of feeding box 2 and communicates with the inner wall, thus conveying the grain and oil to feeding box 2. The bottom of feeding box 2 is connected to conveying pipe 8. Valve b9 is opened, allowing the grain and oil to be conveyed through conveying pipe 8 into guide pipe 10. Guide pipe 10 is connected to filter pipe 11. Filter pipe 11 is connected with three filter screens in sequence. The filter holes of the three filter screens are arranged such that, from guide pipe 10 to connecting pipe 14, the filter holes of the first filter screen are larger than those of the second filter screen, and the filter holes of the second filter screen are larger than those of the third filter screen, thus filtering and removing impurities from the grain and oil in sequence. The cleaned grain and oil is then conveyed to oil storage tank 3 through connecting pipe 14. The oil outlet of the connecting pipe 14 is connected to the oil storage tank 3, so that the grain and oil are stored in the oil storage tank 3. The oil drain pipe 6 is connected to the bottom of the oil storage tank 3 and the oil inlet is connected to the oil storage tank 3. It is used in conjunction with valve a7 to facilitate the discharge of grain and oil in the oil storage tank 3, so as to complete the grain and oil purification and extraction work. After the grain and oil are purified and extracted, the air pump 13 and the air supply pipe 12 pressurize the guide pipe 10, so that the gas pressure flushes out the blockage in the filter structure. Then the water pipe 15 is connected to the water pump, and the water pump is connected to the water supply equipment to achieve the water flushing device. At the same time, the guide pipe 10 is connected to the sewage pipe 16 through valve c. By activating valve c, the oil is discharged. Then the connecting pipe 14 is connected to the filter pipe 11 through valve d, so that the components of the grain and oil purification and extraction device can be used together.

[0021] The working principle of this utility model is as follows: The feeding box 2 is connected to the oil guide pipe 17 and the conveying pipe 8, so that the grain and oil are stored in it and then transported for purification and extraction. After the grain and oil purification and extraction is completed, the inner wall of the feeding box 2 is covered with residual grain and oil. By starting the cylinder 403, the driving end of the cylinder 403 causes the driving rod 404 to pass through the through hole and the sealing sleeves a406 and b407 and move downward in the feeding box 2. The driving rod 404 drives the extrusion plate 405, which moves downward along the inner surface of the feeding box 2, so as to squeeze the residual grain and oil on the inner wall of the feeding box 2 downward into the conveying pipe 8 and discharge it. Meanwhile, after the grain and oil in the oil storage tank 3 are discharged, the remaining grain and oil in the oil storage tank 3 are squeezed out by the extrusion component a4. By connecting the liquid level sensor 408 to the extrusion plate 405, the extrusion plate 405 is located above the inner wall of the oil storage tank 3 and higher than the inner wall of the connecting pipe 14 when not in use. At the same time, the extrusion plate 405 in the feeding box 2 is higher than the inner wall of the conveying pipe 8. The liquid level sensor 408 detects the grain and oil level in the feeding box 2 and the oil storage tank 3, so as to open the valves a7 and b9 in time to transport or discharge the grain and oil, which facilitates the operation of the grain and oil purification and extraction device.

[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
