Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, specifically a tubular magnetic separator for rice. Background Technology

[0002] In large-scale rice production, magnetic separation is a crucial step in ensuring product quality. During rice processing, iron impurities such as nails and iron filings introduced during harvesting and transportation can easily get mixed in. If not removed in time, these impurities can not only affect the taste and safety of the rice but may also damage subsequent rice milling and polishing equipment. Therefore, specialized tubular magnetic separators for rice have become one of the core pieces of equipment in the production line.

[0003] Traditional tubular magnetic separators for rice mainly consist of a conveying pipe, an internal magnetic block assembly, and a casing. During operation, rice flows through the pipe with airflow or a conveyor belt, and ferrous impurities are adsorbed and retained by the magnetic blocks, thus achieving purification. However, this type of equipment has a significant drawback: cleaning the magnetic blocks requires stopping the machine. Currently, the industry commonly uses manual wiping or cleaning with a small brush, which is a cumbersome process: the magnetic separator and related production lines must be shut down first, the power supply to the equipment must be cut off to ensure safety, then the casing must be disassembled to expose the magnetic block assembly, and after cleaning, it must be reassembled and tested before production can resume, affecting magnetic separation efficiency.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide a special tubular magnetic separator for rice to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a special tubular magnetic separator for rice, including a chute with a flow channel formed inside for rice to flow through. Multiple square tubes are integrally formed on the chute and are equidistantly arranged along the axial direction of the chute. A sliding plate is provided inside the square tube to allow the chute to slide radially. The sliding plate has a first circular hole and a second circular hole with the same diameter as the flow channel. Magnetic blocks are arranged inside the first circular hole and the second circular hole.

[0007] Furthermore, it also includes a positioning component disposed on the square tube for locking the sliding of the skateboard. The positioning component includes a positioning pin slidably mounted on the side wall of the square tube, and a positioning hole is provided on the side wall of the skateboard for the positioning pin to be inserted.

[0008] Furthermore, a return spring is sleeved on the outside of the positioning pin. One end of the return spring is connected to the positioning pin, and the other end of the return spring is connected to the side wall of the square tube. The initial elastic force of the return spring pulls the positioning pin into the positioning hole.

[0009] Furthermore, it also includes a locking component disposed inside the first and second circular holes. The magnetic block is fixed inside the first and second circular holes by the locking component. The locking component includes a threaded sleeve rotatably mounted on the inner wall of the first and second circular holes. Multiple threaded sleeves are provided and arranged in a circumferential array on the inner wall of the first and second circular holes. The internal threads of the threaded sleeves are connected to threaded posts. Each of the multiple threaded posts has a clamp installed at one end opposite to the other. The magnetic block is clamped between the multiple clamps.

[0010] Furthermore, guide posts are installed on the inner walls of the first and second circular holes. The guide posts are located inside the threaded sleeve, and the threaded posts are slidably connected to the guide posts.

[0011] Furthermore, connecting flanges are installed at both the top and bottom ports of the chute.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model constructs a dual-magnetic-block alternating working structure by using an integrally formed square tube on the chute, a radially sliding slide plate, and a first and second circular hole with a magnetic block on the slide plate; with the positioning component composed of a positioning pin and a return spring, the working magnetic block can be quickly switched. This design avoids the problem of traditional magnetic separators requiring shutdown for cleaning, avoids production interruptions caused by shutdown, increases effective operating time, and enhances the enterprise's large-scale production capacity.

[0013] 2. This utility model, through a locking assembly consisting of a threaded sleeve, a threaded post, and a clamp, combined with the positioning function of the guide post, allows for quick assembly and disassembly of the fixed magnetic block without disassembling the equipment casing, thereby reducing the overall cost of enterprises from multiple dimensions such as manpower, equipment wear and tear, and material waste.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 This utility model provides a technical solution: a special tubular magnetic separator for rice, including a chute 1, which has a flow channel formed inside for rice to flow through. Multiple square tubes 3 are integrally formed on the chute 1. The multiple square tubes 3 are equidistantly arranged along the axial direction of the chute 1. A sliding plate 4 is provided inside the square tube 3 to slide radially like the chute 1. The sliding plate 4 has a first circular hole 8 and a second circular hole 9 with the same diameter as the flow channel. Magnetic blocks 10 are provided inside the first circular hole 8 and the second circular hole 9.

[0018] Specifically, the system uses a chute 1 as the main body, with an internal flow channel for rice circulation. Multiple square tubes 3, equidistantly arranged along the axial direction of the chute 1, are integrally formed with the chute 1. Each square tube 3 contains a sliding plate 4 that can slide radially along the chute 1. The first circular hole 8 and the second circular hole 9 on the sliding plate 4 are of the same diameter as the flow channel and contain built-in magnetic blocks 10. By sliding the sliding plate 4, the first circular hole 8 or the second circular hole 9 can be switched and aligned with the flow channel, allowing one set of magnetic blocks 10 to work while the other set is cleaned. This dual-magnetic-block-10 alternating working structure overcomes the limitation of traditional magnetic separators where a single set of magnetic blocks 10 must be stopped for cleaning. It enables simultaneous magnetic separation and magnetic block 10 cleaning, solving the production interruption problem caused by downtime for cleaning and improving the continuous operation capability of the production line.

[0019] As a technical optimization of this utility model, it also includes a positioning component set on the square tube 3 for locking the sliding plate 4. The positioning component includes a positioning pin 5 slidably installed on the side wall of the square tube 3, and a positioning hole 7 is provided on the side wall of the sliding plate 4 for the positioning pin 5 to be inserted.

[0020] Specifically, a positioning component is provided on the square tube 3, consisting of a positioning pin 5 slidably installed on the side wall of the square tube 3 and a positioning hole 7 on the side wall of the slide plate 4. When the slide plate 4 slides to the working position, the positioning pin 5 is inserted into the positioning hole 7 to lock and fix the slide plate 4.

[0021] As a technical optimization of this utility model, a return spring 6 is sleeved on the outside of the positioning pin 5. One end of the return spring 6 is connected to the positioning pin 5, and the other end of the return spring 6 is connected to the side wall of the square tube 3. The initial elastic force of the return spring 6 pulls the positioning pin 5 into the positioning hole 7.

[0022] Specifically, a return spring 6 is sleeved on the outside of the positioning pin 5, with its two ends connected to the positioning pin 5 and the side wall of the square tube 3, respectively. Under the action of the initial elastic force, the positioning pin 5 is always pulled into the positioning hole 7. When the slide plate 4 needs to be switched, the external force pulls the positioning pin 5 to compress the spring. After cleaning, it is released and automatically resets and locks, realizing the automatic locking function of the positioning pin 5 and simplifying the operation process.

[0023] As a technical optimization of this utility model, it also includes a locking component disposed inside the first circular hole 8 and the second circular hole 9. The magnetic block 10 is fixed inside the first circular hole 8 and the second circular hole 9 by the locking component. The locking component includes a threaded sleeve 14 rotatably installed on the inner wall of the first circular hole 8 and the second circular hole 9. Multiple threaded sleeves 14 are provided, and multiple threaded sleeves 14 are arranged in a circumferential array on the inner wall of the first circular hole 8 and the second circular hole 9. The threaded sleeve 14 is internally threaded with a threaded post 12. Each of the multiple threaded posts 12 has a clamp 13 installed at one end opposite to the other. The magnetic block 10 is clamped between the multiple clamps 13.

[0024] Specifically, multiple rotatably mounted threaded sleeves 14 are arranged in a circumferential array on the inner wall of the first circular hole 8 and the second circular hole 9. The threaded column 12 with internal thread connection is equipped with a clamp 13. Rotating the threaded sleeve 14 can drive the threaded column 12 to move, so that the multiple clamps 13 can simultaneously clamp or loosen the magnetic block 10, thereby realizing the rapid assembly and disassembly of the magnetic block 10.

[0025] As a technical optimization of this utility model, a guide post 11 is also installed on the inner wall of the first circular hole 8 and the second circular hole 9. The guide post 11 is located inside the threaded sleeve 14, and the threaded post 12 is slidably connected to the guide post 11.

[0026] Specifically, the guide post 11 on the inner wall of the first circular hole 8 and the second circular hole 9 passes through the inside of the threaded sleeve 14, and the threaded post 12 is slidably connected to the guide post 11, providing guiding constraints for the movement of the threaded post 12, preventing the threaded post 12 from rotating synchronously with the threaded sleeve 14, and ensuring that the clamp 13 moves smoothly.

[0027] As a technical optimization of this utility model, a connecting flange 2 is installed at both the top and bottom ports of the chute 1.

[0028] Specifically, the connecting flanges 2 installed at the top and bottom ports of the chute 1 are connected to other equipment in the production line by bolts to achieve a sealed connection, which improves the convenience and sealing of the connection between the equipment and the production line, solves the problems of time-consuming equipment docking and possible material leakage in the background technology, and reduces installation and commissioning time and material loss.

[0029] This utility model discloses a rice-specific tubular magnetic separator that achieves the function of cleaning the magnetic block 10 without stopping the machine through structural innovation. Its overall working principle is as follows: The core component of this magnetic separator is the chute 1, which has a formed flow channel inside for the normal flow of rice. The connecting flanges 2 at the top and bottom of the chute 1 are used to connect with other equipment in the production line. The multiple square tubes 3 arranged equidistantly along the axial direction of the chute 1 are a key innovative structure. Each square tube 3 is equipped with a sliding plate 4 that can slide radially along the chute 1. The first circular hole 8 and the second circular hole 9 on the sliding plate 4 are equipped with magnetic blocks 10, and the two circular holes are equal in diameter to the flow channel. During normal operation, the sliding plate 4 is used to align the first round hole 8 with the flow channel of the chute 1. At this time, the positioning pin 5 in the positioning component is inserted into the positioning hole 7 of the sliding plate 4 under the action of the return spring 6 to complete the locking. When the rice flows through the channel, iron impurities are attracted by the magnetic block 10 in the first round hole 8. When it is necessary to clean the magnetic block 10, the positioning pin 5 is pulled outward to disengage it from the positioning hole 7. The sliding plate 4 is switched to align the second round hole 9 with the flow channel. After re-locking the positioning pin 5, the magnetic separation operation can continue. At this time, the magnetic block 10 in the first round hole 8 can be cleaned offline. The magnetic block 10 is fixed by a locking assembly. Rotating the threaded sleeve 14 can drive the threaded column 12 to slide along the guide column 11, so that multiple clamps 13 can clamp or release the magnetic block 10 simultaneously, which facilitates the replacement and maintenance of the magnetic block 10. This design of alternating operation of the two magnetic blocks 10 solves the problem that traditional equipment must be stopped for cleaning, and significantly improves production efficiency.
