Abstract
Description
Technical Field
[0001] This utility model relates to the field of edible oil processing technology, and in particular to an edible oil screening and impurity removal device. Background Technology
[0002] Existing edible oil particle screening and impurity removal devices typically include a frame, a feed cylinder, a coarse screen, and a fine screen. The coarse screen removes large particles such as stalks from the oil, while the fine screen works in conjunction with an air separation mechanism to remove dust, thus separating the oil from the impurities.
[0003] During the coarse screening process, a sludge collection trough is usually set at the discharge end of the coarse screen plate to collect large particles of debris such as stalks that are screened out, so that they can be discharged smoothly. Usually, the length of the coarse screen plate is shorter than that of the fine screen plate. As a result, during the screening process, due to the short screening distance, some oil enters the sludge collection trough along with the large particles of debris and is discharged with them, which leads to waste of oil and increases processing costs. If the oil screening distance is extended by increasing the coarse screen plate to reduce the probability of oil being discharged with large particles of debris, the overall length of the equipment will increase, requiring a larger floor space.
[0004] Therefore, there is an urgent need for an edible oil screening and impurity removal device that can reduce the probability of oil being discharged with large particles of impurities without increasing the equipment's floor space. Utility Model Content
[0005] The purpose of this invention is to provide an edible oil screening and impurity removal device that can reduce the probability of oil being discharged with large particles of impurities during the coarse screening process, while not excessively increasing the equipment's floor space. It has a compact structure and strong practicality.

A fine screen plate is installed on the frame below the guide cylinder and the first coarse screen plate, and a vibration motor is installed at the bottom of the fine screen plate.
[0007] Preferably, the inside of the feed cylinder is a rectangular cavity.
[0008] Preferably, the first coarse screen plate has an inverted V-shaped structure, and the second coarse screen plate is provided on both sides of the guide cylinder, and the second coarse screen plate is inclined downward from the end away from the discharge port to the end closer to the discharge port.

[0011] Preferably, the feed cylinder and the fine screen plate are connected by a connecting plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are: by setting the first coarse screen plate inclined inside the guide cylinder and setting the second coarse screen plate outside the guide cylinder, this utility model can extend the path of the oil coarse screen without increasing the area occupied by the device, improve the coarse screen effect of the oil, reduce the probability of oil entering the sludge receiving tank with large particles, reduce oil waste, and has a simple structure and strong practicality. Attached Figure Description
[0017] Figure 1 This is a schematic diagram of the structure of an embodiment of this application; Figure 2 This is a cross-sectional view of the feed tube according to an embodiment of this application. Detailed Implementation
[0018] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments: like Figures 1-2As shown, the edible oilseed screening and impurity removal device of this utility model includes a frame 1. An air separation mechanism 2 is provided on the side of the frame 1 near the discharge port. The air separation mechanism 2 is a conventional technology commonly used in rapeseed screening machines in the prior art. Its lower dust removal inlet is located above the fine screen plate 3. This is a conventional setting in the prior art. Those skilled in the art can clearly understand this in combination with the structure of the rapeseed screening machine. In addition, this part is not part of the improved technology of this application, so it will not be described in detail.
[0019] A vertically connected guide cylinder 4 is provided on the frame 1. The interior of the guide cylinder 4 is preferably a rectangular cavity. A first coarse screen plate 5 is inclined downwards inside the guide cylinder 4 and extends through a discharge hole 6 on the guide cylinder 4. A second coarse screen plate 7 is inclined downwards below the first coarse screen plate 5. A sludge receiving trough 8 is provided at the outlet end of the second coarse screen plate 7. The sludge receiving trough 8 is arranged along the width direction of the frame 1 and is inclined from high to low to facilitate the smooth discharge of large particles using the height difference. The sludge receiving trough 8 extends from one side of the frame 1 from its outlet end, so that the large particles can be discharged smoothly using the height difference. 1. An external receiving container is placed to receive the debris discharged from the sludge receiving trough 8; a fine screen plate 3 is installed on the frame 1 below the guide cylinder 4 and the first coarse screen plate 5. The second coarse screen plate 7 is connected to the fine screen plate 3 by a connecting rod 9 to ensure that the second coarse screen plate 7 vibrates with the fine screen plate 3 during the screening process, wherein the second coarse screen does not contact the frame 1; in addition, the fine screen plate 3 is set on the frame 1 by a spring 11, which is a conventional setting in the existing screening structure to improve screening efficiency and reduce the probability of clogging; a vibration motor is installed at the bottom of the fine screen plate 3. During operation, the oil is poured into the feed cylinder 4, and the vibrating motor is turned on. The oil first passes through the first coarse screen plate 5 for filtration. At this time, some of the oil will fall onto the fine screen plate 3 below. The large particles and some oil that are screened out will be discharged from the feed cylinder 4 into the second coarse screen plate 7, where it will continue to be screened. This improves the coarse screening effect of the oil by extending the screening path in three-dimensional space, reducing the probability that the oil will fall into the sludge collection tank 8 along with the large particles during the coarse screening process, and reducing the waste of oil.
[0020] Furthermore, the first coarse screen plate 5 has an inverted V-shaped structure, and second coarse screen plates 7 are provided on both sides of the feed cylinder 4. The second coarse screen plates 7 are inclined downwards from the end away from the discharge port to the end closer to the discharge port, with an inclination angle of no more than 30 degrees. This facilitates the flow of material to the outlet, accelerates the dispersion and uniform distribution of material, reduces the probability of material clogging the mesh, and also reduces the impact and friction of material on the second coarse screen plate 7, extending its service life. The inverted V-shaped structure of the first coarse screen plate 5 enables simultaneous screening operations on both sides of the feed cylinder 4, improving screening efficiency and preventing the accumulation of oil on the first coarse screen plate 5.
[0021] Furthermore, the guide cylinder 4 is elastically mounted on the frame 1, such as... Figure 1 As shown, the guide cylinder 4 is surrounded by support rods 10, which are connected to the top of the frame 1 via springs 11. A limiting hole is provided at the top of the frame 1, and a limiting rod is provided at the bottom of the support rods 10. The limiting rod passes through the middle of the spring 11 and is located within the limiting hole. The elastic design of the guide cylinder 4 increases the vibration amplitude of the guide cylinder 4 during operation, enhancing the screening efficiency of the first coarse screen plate 5. The limiting rod and limiting hole limit the guide cylinder 4, allowing it to move only vertically. Furthermore, the guide cylinder 4 and the fine screen plate 3 are connected by a connecting plate 14, enabling them to be integrated. This allows the guide cylinder 4 to vibrate synchronously with the fine screen plate 3, improving the efficiency of oil screening.
[0022] Furthermore, a sealing plate 12 is adjustablely installed on the guide cylinder 4 above the discharge hole 6. By adjusting the up and down movement of the sealing plate 12, the opening size of the discharge hole 6 can be adjusted, thereby adjusting the discharge efficiency of the oil from the first coarse screen plate 5 to the second coarse screen plate 7. Specifically, mounting plates are provided at both the upper and lower ends of the guide cylinder 4, and an adjusting screw 13 is rotatably installed between the two mounting plates. One end of the sealing plate 12 has a threaded hole that is threadedly connected to the adjusting screw 13, and the other end of the sealing plate 12 is slidably connected to a guide rod provided on the guide cylinder 4. When the sealing plate 12 needs to be adjusted, the adjusting screw 13 can be rotated.
[0023] In use, the device is activated, and the oil to be screened is poured into the feed cylinder 4. The oil first passes through the first coarse screen plate 5 for filtration. At this time, some oil will fall onto the fine screen plate 3 below. Large particles and some oil that have been screened out will be discharged from the feed cylinder 4 and enter the second coarse screen plate 7 for further screening. By extending the screening path in three-dimensional space, the coarse screening effect of the oil is improved, and the probability of oil falling into the sludge collection tank 8 along with large particles during the coarse screening process is reduced, thus reducing oil waste. Finally, the oil that falls onto the fine screen plate 3 is discharged after fine screening and dust removal.
