Description

Technical Field

[0001] This utility model relates to the field of wheat processing technology, and in particular to a magnetic separation device for peach crisp wheat flour. Background Technology

[0002] In the production of baked goods such as peach shortbread, the purity of wheat flour directly affects product quality and safety. Impurities such as iron filings and metal particles may originate from raw material storage, wear and tear on processing equipment, or transportation. If mixed into flour, they can not only damage processing machinery (such as dough mixers and sheeters) but also pose food safety risks. Therefore, efficiently removing magnetic impurities (such as iron filings) from wheat flour is a key step in the flour processing industry.

[0003] Traditional equipment relies on the natural falling or horizontal conveying of flour, which makes it difficult for iron filings to be fully encapsulated by flour particles. This makes it difficult for the magnetic adsorption device to fully contact the impurities and adsorb the iron filings. In addition, wheat raw materials often contain non-magnetic impurities such as sand, broken wheat husks, and plant fibers. Existing magnetic separation equipment can only complete a single iron removal process, requiring additional equipment such as vibrating screens and air separators for secondary impurity removal. This not only increases equipment investment and energy consumption costs, but may also cause secondary contamination of flour due to multiple transfer links. Therefore, a magnetic separation device for peach crisp wheat flour is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a magnetic separation device for peach crisp wheat flour, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A magnetic separator for peach crisp wheat flour includes a tank. A through hole is provided on the bottom side of the tank, and a discharge pipe is installed within the through hole, connected to the tank. A sieve plate is installed inside the discharge pipe, and an elastic component is installed below the sieve plate. A protrusion is fixedly installed on the top side of the sieve plate. Two limiting plates are fixedly installed on the inner wall of the tank, with a portion of each limiting plate abutting against the top side of the sieve plate. A motor is fixedly installed on one side of the tank, with its output end rotating through the tank and rotatably connected to the inner wall of one side of the tank. Multiple lifting plates are fixedly installed on the outer side of the motor's output end. A pushing component and a removal component are respectively installed on both sides of the tank.

[0007] Preferably, the elastic component includes connecting plates fixedly installed on both inner walls of the discharge pipe, and a set of springs fixedly installed on the top side of each of the two connecting plates, with two springs in each set, and the other end of each set of springs being fixedly connected to the bottom side of the screen plate.

[0008] Preferably, inclined blocks are fixedly installed on the top sides of both connecting plates, and the two inclined blocks are symmetrically arranged and both are inclined.

[0009] Preferably, the pushing assembly includes multiple circular holes on both sides of the tank body, a side plate fixedly installed on one side of the tank body, the side plate being L-shaped, a first electric push rod fixedly installed on one side of the side plate, the output end of the first electric push rod passing through the side plate and fixedly connected to a fixing plate, and multiple magnetic pillars fixedly installed on the other side of the fixing plate, the multiple magnetic pillars being located in the multiple circular holes respectively, and the size of the multiple magnetic pillars being smaller than the size of the circular holes.

[0010] Preferably, the removal component includes a fixing frame fixedly installed on the other side of the tank. The fixing frame is U-shaped. A second electric push rod is fixedly installed on both the top and bottom sides of the fixing frame. The output ends of the two second electric push rods pass through the fixing frame and are fixedly connected to scrapers. Both scrapers have arc-shaped grooves that are the same as multiple round holes. The multiple arc-shaped grooves are respectively adapted to multiple magnetic columns. A collection box is fixedly installed on the other side of the fixing frame.

[0011] Preferably, the top side of the tank is provided with a feed inlet, which is connected to the tank body. A guide plate is fixedly installed inside the tank body, and the guide plate is V-shaped and located below the feed inlet.

[0012] Preferably, two support legs are fixedly installed on the outside of the tank, and a collection box is provided between the two support legs, with the discharge pipe facing the collection box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The motor drives the lifting plate to rotate and lift the wheat, fully exposing the iron filings. Combined with the magnetic pillars on both sides of the tank, the iron filings adsorption efficiency is significantly improved. The elastic component under the screen plate is linked with the protrusion on the top side of the screen plate. When the lifting plate rotates and squeezes the protrusion, the spring is compressed and drives the screen plate to move down. After the lifting plate leaves, the spring returns to its original position, causing the screen plate to vibrate back and forth, preventing the screen holes from clogging. Two limit plates limit the upward stroke of the screen plate to prevent the lifting plate from hitting the side of the screen plate, protecting the screen plate and the spring. The inclined block is set at an angle on the top side of the connecting plate, which can guide the wheat filtered by the screen plate to slide down the inclined surface, avoiding accumulation on the top of the connecting plate and ensuring that the wheat falls smoothly into the collection box.

[0015] 2. The first electric push rod in the push assembly moves the fixed plate and the magnetic column, allowing the magnetic column that adsorbs iron filings to pass through the fixed frame. The two second electric push rods in the removal assembly drive the scrapers to move towards each other. Their arc-shaped grooves fit against the outside of the magnetic column. When the magnetic column moves in the opposite direction, the scrapers scrape the iron filings into the collection box, achieving centralized cleaning of iron filings. The V-shaped guide plate is located below the feed inlet, allowing the wheat to be diverted and contact the magnetic column below the guide plate, completing the initial magnetic separation. The screen plate in the discharge pipe can block non-magnetic impurities such as sand and gravel. Together with the magnetic column, it achieves dual filtration of magnetic separation and screening, eliminating the need for additional impurity removal equipment, reducing equipment investment and energy consumption, avoiding flour transfer contamination, and improving the overall magnetic separation efficiency.

[0021] 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.

[0022] Reference Figure 1-4A magnetic separation device for peach crisp wheat flour includes a tank 1. A through hole is provided on the bottom side of the tank 1, and a discharge pipe 4 is installed inside the through hole, connected to the tank 1. A screen plate 5 is installed inside the discharge pipe 4, and an elastic component is installed below the screen plate 5. A protrusion 9 is fixedly installed on the top side of the screen plate 5. Two limiting plates 10 are fixedly installed on the inner wall of the tank 1, with a portion of each limiting plate 10 abutting against the top side of the screen plate 5. A motor 11 is fixedly installed on one side of the tank 1, with its output end rotatably penetrating the tank 1 and rotatably connected to the inner wall of one side of the tank 1. Multiple lifting plates 12 are fixedly installed on the outer side of the output end of the motor 11. A pushing component and a removal component are respectively provided on both sides of the tank 1. The device utilizes multiple lifting plates... When all the wheat has flowed into the tank 1, the start motor 11 will drive the multiple lifting plates 12 fixedly connected to the outside of the output end to rotate. The multiple lifting plates 12 can lift the wheat accumulated at the bottom of the tank 1 during the rotation. The iron filings in the lifted wheat will be more easily attracted by the multiple magnetic columns 16. The upward movement of the screen plate 5 can be limited by the two limiting plates 10 set on the inner wall of the tank 1. When the screen plate 5 returns to its original position and moves upward under the elastic action of the spring 7, the bottom of the limiting plate 10 contacts the top side of the screen plate 5 to prevent it from moving too high. This prevents the lifting plates 12 from directly hitting the side of the screen plate 5 when rotating, thereby protecting the screen plate 5 and the two sets of springs 7 at the bottom from impact damage and ensuring the stability and durability of the equipment operation.

[0023] Specifically, the elastic component includes connecting plates 6 fixedly installed on both inner walls of the discharge pipe 4. A set of springs 7 is fixedly installed on the top side of each of the two connecting plates 6, with two springs in each set. The other ends of both sets of springs 7 are fixedly connected to the bottom side of the screen plate 5. Inclined blocks 8 are fixedly installed on the top side of each of the two connecting plates 6. The two inclined blocks 8 are symmetrically arranged and inclined. With the two sets of springs 7, when the lifting plate 12 rotates, it will squeeze the protrusions 9. The squeezed protrusions 9 will cause the screen plate 5 to move downwards. At this time, the bottom of the screen plate 5... The two sets of springs 7 fixed on the side will contract. When the lifting plate 12 passes the protrusion 9, the elastic force of the multiple springs 7 will be restored, thereby driving the sieve plate 5 to reset. During the reset and the process of the lifting plate 12 contacting the protrusion 9, the sieve plate 5 will generate a certain vibration, thereby preventing impurities from clogging the sieve holes. By setting two inclined blocks 8, the two inclined blocks 8 can prevent the wheat filtered by the sieve plate 5 from accumulating on the top side of the connecting plate 6, thereby guiding the falling wheat and making it fall accurately into the collection box 22.

[0024] Specifically, the pushing component includes multiple circular holes on both sides of the tank body 1. A side plate 13, L-shaped, is fixedly installed on one side of the tank body 1. A first electric push rod 14 is fixedly installed on one side of the side plate 13. The output end of the first electric push rod 14 passes through the side plate 13 and is fixedly connected to a fixing plate 15. Multiple magnetic pillars 16 are fixedly installed on the other side of the fixing plate 15. The multiple magnetic pillars 16 are located in the multiple circular holes, and the size of the multiple magnetic pillars 16 is smaller than the size of the circular holes. The removal component includes a fixing frame 17, U-shaped, fixedly installed on the other side of the tank body 1. Second electric push rods 18 are fixedly installed on the top and bottom sides of the fixing frame 17. The output ends of the two second electric push rods 18 pass through the fixing frame 17 and are fixedly connected to scrapers 19. The two scrapers 19 are provided with arc-shaped grooves identical to the multiple circular holes, and the multiple arc-shaped grooves are respectively adapted to the multiple magnetic pillars 16. A collection box 20 is fixedly installed on the other side of the fixing frame 17. When it is necessary to clean the iron filings on the magnetic posts 16, the first electric push rod 14 is activated to drive multiple magnetic posts 16 on one side of the fixing plate 15 toward the fixing frame 17. Then, the area where the multiple magnetic posts 16 have attracted iron filings will pass through two scrapers 19. Then, the two second electric push rods 18 are activated simultaneously to bring the two scrapers 19 closer together. Then, the arc-shaped grooves opened on both scrapers 19 will form a circle when they are put together. The arc-shaped grooves that form a circle are just in contact with the outer side of the magnetic posts 16. After they are put together, the first electric push rod 14 is activated again to drive the fixing plate 15 to reset. At this time, during the synchronous reset process of multiple magnetic posts 16, the iron filings attached to their surfaces will be scraped off by the two scrapers 19. The scraped iron filings will fall into the collection box 20 for storage due to inertia, which will facilitate subsequent unified processing.

[0025] Specifically, a feed inlet 3 is provided on the top side of the tank body 1, and the feed inlet 3 is connected to the tank body 1. A guide plate 21 is fixedly installed inside the tank body 1. The guide plate 21 is V-shaped and located below the feed inlet 3. Two support legs 2 are fixedly installed on the outside of the tank body 1. A collection box 22 is provided between the two support legs 2. The discharge pipe 4 faces the collection box 22. The feed inlet 3 is used for feeding wheat. The guide plate 21 can guide the wheat falling into the tank body 1 so that it is initially attracted by the two magnetic columns 16. The collection box 22 can collect the wheat filtered by the sieve plate 5.

[0026] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0027] In operation: Wheat to be magnetically separated is poured into tank 1 through inlet 3. The wheat flows to both sides along V-shaped guide plate 21. Since multiple round holes on the side wall of tank 1 are equipped with magnetic pillars 16, and the two farthest magnetic pillars 16 are located below guide plate 21, the wheat after being diverted comes into contact with these two magnetic pillars 16 during its fall, achieving initial adsorption of iron filings. After all the wheat has fallen to the bottom of tank 1, motor 11 is started to drive lifting plate 12 to rotate. Lifting plate 12 lifts the accumulated wheat to form a powder mist, fully exposing the iron filings, which facilitates further adsorption by the multiple magnetic pillars 16 in tank 1. At the same time, sieve plate 5 in discharge pipe 4 filters the falling wheat. Sieve plate 5 can also block non-magnetic impurities such as sand and broken shells, allowing only qualified flour to pass through. Through the protrusions 9 on the top side of sieve plate 5, lifting plate 12 will squeeze protrusions 9 when rotating, thereby compressing the bottom of sieve plate 5. Spring 7 moves downwards. After lifting plate 12 rotates past protrusion 9, spring 7 elastically resets and pushes screen plate 5 upwards. This reciprocating motion causes screen plate 5 to vibrate at high frequency, effectively preventing screen hole blockage and improving screening efficiency. After the wheat is basically processed, the first electric push rod 14 is activated, pushing fixed plate 15 to move magnet column 16 towards fixed frame 17. When magnet column 16 adsorbs iron filings and passes through two scrapers 19, the second electric push rods 18 on the top and bottom sides are activated simultaneously, driving scrapers 19 to move towards each other until they are in contact. At this time, the first electric push rod 14 is activated again in the opposite direction. During the reset process of magnet column 16, scraper 19 can scrape off the iron filings adsorbed on its surface. The iron filings fall into collection box 20 for centralized processing due to inertia. The pure wheat filtered by screen plate 5 falls into collection box 22 through discharge pipe 4. Non-magnetic impurities remaining in tank 1 can be manually cleaned by opening the tank door. The magnetic separation process of wheat is thus completed.
