Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice processing technology, specifically to a magnetic separator for the feed inlet of rice processing equipment. Background Technology
[0002] Rice is produced by processing paddy rice through a series of steps, including cleaning, hulling, milling, and final screening. These multiple processing steps make it easy for metal particles and iron filings to become mixed into the rice. The presence of these metal impurities reduces the quality of the final rice product and can even damage processing equipment. Magnetic separation equipment is typically used to remove these impurities. However, existing magnetic separation equipment often struggles to adsorb metal impurities from the rice, as some impurities are located at the bottom of the paddy and are difficult for the electromagnets to attract. This necessitates multiple magnetic separation processes, directly impacting the efficiency. Furthermore, the fixed position of the electromagnets in existing equipment means that when separating small amounts of paddy rice, the metal impurities at the top layer are relatively far from the electromagnets, affecting their adsorption and ultimately impacting the equipment's performance.

[0017] Reference Figures 1 to 4 As shown, this utility model provides a magnetic separator for the feed inlet of a rice processing equipment, comprising: a housing 2, which is fixedly connected to the feed inlet of the main body 1 of the rice processing equipment; a temporary storage box 13 is fixedly connected to the top of the inner cavity of the housing 2; a partition plate 12 is symmetrically connected to the discharge port opened on the lower surface of the temporary storage box 13; a positioning frame 8 is fixedly connected to the lower surface of the temporary storage box 13; an auxiliary shell 10 and a magnetic shielding plate 11 are fixedly connected to the positioning frame 8; a secondary electromagnet 9 is fixedly connected to the auxiliary shell 10; an auxiliary plate 7 is fixedly connected to the middle of the inner cavity of the housing 2; a main electromagnet 6 is fixedly connected to the lower surface of the auxiliary plate 7; a guide plate 3 is symmetrically connected to the bottom of the inner cavity of the housing 2; a through-hole is opened at the lower end of the inner cavity of the housing 2; a positioning plate 5 is fixedly connected to the outer side of the housing 2 near the through-hole; and a collection box 4 is movably connected to the through-hole through the positioning plate 5.
[0018] In this embodiment, when adding paddy rice into the main body 1 of the rice processing equipment, the paddy rice is first poured in through the inlet on the upper surface of the box 2. The paddy rice falls into the temporary storage box 13, and under the interference of the partition plate 12, the paddy rice is divided into four groups and continuously slides down in a waterfall shape within the binding frame 8. The paddy rice sliding out from the lower end of the binding frame 8 will hit the surface of the auxiliary plate 7 and slide along the inclined surface of the auxiliary plate 7 to both sides. Then, the paddy rice can smoothly fall into the inlet of the main body 1 of the rice processing equipment along the inclined surface of the guide plate 3. When the paddy rice slides down in the binding frame 8, the metal impurities mixed in with the paddy rice will be attracted and fixed on the surface of the auxiliary shell 10 by the secondary electromagnet 9, which has been activated, so that the paddy rice and metal impurities can be smoothly separated. The magnetic separator effectively separates the rice grains from the auxiliary plate 7. During the process of the rice grains impacting the auxiliary plate 7, a small amount of metal impurities mixed in with the rice grains are attracted and fixed on the surface of the auxiliary plate 7 by the main electromagnet 6, which has been activated. This allows for secondary magnetic separation between the rice grains and the metal impurities, thereby enhancing the magnetic separation effect of the magnetic separator on the rice grains, improving the magnetic separation efficiency of the rice grains, and ensuring the safety of subsequent processing equipment. When it is necessary to clean the metal impurities in the magnetic separator, first push the collection box 4 into the housing 2. After the collection box 4 is fully embedded in the housing 2, turn off the switches of the main electromagnet 6 and the auxiliary electromagnet 9, so that the metal impurities can naturally slide into the collection box 4 under the action of gravity. Then, remove the collection box 4 to complete the cleaning of the metal impurities.
[0019] In a preferred embodiment, the temporary storage box 13 has a square structure, the lower end of the temporary storage box 13 has an isosceles trapezoidal structure, and the discharge port on the lower surface of the temporary storage box 13 has a rectangular structure. At the same time, the outer side of the temporary storage box 13 and the upper part of the inner cavity of the box body 2 are matched.
[0020] In this embodiment, as Figure 1 and Figure 3 The structure at the bottom of the temporary storage box 13 can effectively prevent rice from remaining in the temporary storage box 13 and ensure that all rice can slide down through the discharge port.
[0021] As a preferred embodiment, there are three sets of partition plates 12. All three sets of partition plates 12 are semi-cylindrical structures, and the upper surface of all three sets of partition plates 12 is arc-shaped protrusion. At the same time, the partition plates 12 and the discharge port are combined to form a shaped structure.
[0022] In this embodiment, as Figure 1 and Figure 3 The structure of the partition plate 12 allows the rice grains in the temporary storage box 13 to slide down in multiple groups, thereby effectively reducing the overall thickness of the rice grains during the sliding process. This helps to enhance the adsorption and fixation effect of the auxiliary electromagnet 9 and the main electromagnet 6 on the metallic impurities mixed in the rice grains.
[0023] In a preferred embodiment, the beam positioning frame 8 has a square cylindrical structure. The dimensions of the inner cavity of the beam positioning frame 8 and the discharge port are matched. The inner cavity of the beam positioning frame 8 is fixedly connected to two sets of auxiliary shells 10 and one set of magnetic shielding plates 11 relative to the position of the partition plate 12. At the same time, the magnetic shielding plate 11 is located between the two sets of auxiliary shells 10, and the thickness of the magnetic shielding plate 11 and the auxiliary shells 10 is smaller than the diameter of the partition plate 12.
[0024] In this embodiment, as Figure 1 and Figure 3 The setting of the beam frame 8 can help limit the range of rice falling, thereby helping to improve the adsorption and fixation effect of the auxiliary electromagnet 9 and the main electromagnet 6 on metal impurities. At the same time, the magnetic shielding plate 11 is made of magnetic shielding material, which can effectively reduce the probability of mutual interference between the two sets of auxiliary electromagnets 9 and ensure that both sets of auxiliary electromagnets 9 can work normally.
[0025] In a preferred embodiment, the auxiliary shell 10 has a square cylindrical structure, the auxiliary electromagnet 9 is fixedly connected inside the auxiliary shell 10, and the magnetic shielding plate 11 has a rectangular structure. The outer side of the auxiliary shell 10 and the magnetic shielding plate 11 are matched in size. At the same time, the cross section formed by the combination of the beam frame 8, the auxiliary shell 10 and the magnetic shielding plate 11 has a V-shaped structure.
[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3The auxiliary shell 10 can effectively reduce the chance of accidental damage to the auxiliary electromagnet 9, and can also improve the efficiency of the adsorbed and fixed metal impurities falling back down after the auxiliary electromagnet 9 is turned off.
[0027] In a preferred embodiment, the two sets of guide plates 3 fixedly connected to the inner cavity of the housing 2 are both right-angled triangular prism structures, and the auxiliary plate 7 fixedly connected to the inner cavity of the housing 2 is rectangular in structure. The end face of the auxiliary plate 7 is fan-shaped, and the size of the upper surface of the auxiliary plate 7 is larger than the size of the lower opening of the beam frame 8.
[0028] In this embodiment, as Figure 1 and Figure 2 The guide plate 3 can effectively reduce the chance of rice residue inside the box 2, ensuring that the rice after magnetic separation can fall smoothly into the feed inlet of the main body 1 of the rice processing equipment. At the same time, the auxiliary plate 7 allows the falling rice to undergo a second magnetic separation process, thereby further enhancing the separation effect of the magnetic separator on the metal impurities mixed in the rice.
[0029] As a preferred embodiment, the positioning plate 5 has a cuboid structure, the end face of the positioning plate 5 has a C-shaped structure, and the collection box 4 connected to the inner cavity of the positioning plate 5 has a frustum-shaped structure. At the same time, the inclined surface of the outer side of the collection box 4 is in contact with the inclined surface of the guide plate 3.
[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 4 The positioning plate 5 helps to enhance the stability of the movable connection between the collection box 4 and the housing 2. The upper opening of the collection box 4 has a frustum-shaped structure, which ensures that metal impurities can fall smoothly along the guide plate 3 and the inclined surface of the collection box 4, thereby improving the cleaning efficiency of the magnetic separator.
[0031] The magnetic separator for the rice processing equipment inlet of this utility model, through the cooperation of temporary storage box 13, separator plate 12, auxiliary electromagnet 9, auxiliary plate 7 and main electromagnet 6, enables the magnetic separator to perform multiple magnetic separation processes on rice, thereby improving the magnetic separation efficiency of the rice. At the same time, it can also perform comprehensive magnetic separation of metal impurities in different locations within the rice, enhancing the magnetic separation effect of the rice. Furthermore, the auxiliary shell 10 and auxiliary plate 7 can generate temporary magnetic force through the cooperation of auxiliary electromagnet 9 and main electromagnet 6, respectively.
