Description

Technical Field

[0001] This utility model belongs to the field of feed processing technology, specifically relating to a device for removing iron slag from feed raw materials. Background Technology

[0002] Common feeds consist of one or more types of coarsely ground straw as the main ingredient, with appropriate amounts of feed additives added. Since livestock cannot distinguish between different types of feed, the presence of iron in the feed will generally harm them.

[0003] Iron can enter feed in two ways. One is through the presence of iron filings in the raw materials themselves. For example, grain raw materials purchased in large quantities by feed production companies often contain a large amount of iron impurities, and various iron objects can easily be mixed in during the transportation and storage of grain raw materials. The other way is through the introduction of iron filings during feed production and processing (such as cutting, transshipment, and other steps involving the operation of metal machinery, or iron filings from dust). Once these iron filings are mixed into the final processed product, they will affect the health of livestock and thus harm the interests of farmers.

[0004] To prevent animals from ingesting iron slag, iron slag removal is necessary during feed production. However, existing methods for removing iron slag in feed often involve installing plate electromagnets on a conveyor belt. Straw-based feeds are relatively coarse, with varying lengths ranging from over ten centimeters to just a few millimeters. The iron slag mixed in with these feeds also varies in size. The material layer is thick during transport. While this method can easily remove larger iron filings, smaller ones are difficult to remove due to obstructions from straw and their small size. As a result, the iron slag removal effect is relatively poor, affecting the quality of the feed product. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a feed raw material iron slag removal device. This solves the problem that existing feed iron slag removal methods often use plate electromagnets mounted on a conveyor belt. For example, straw-based feeds are relatively coarse, with varying lengths (ranging from over ten centimeters to just a few millimeters), and the iron slag mixed within them also varies in size. Furthermore, the material layer during conveying is thick. While this method easily removes larger iron filings, smaller ones are difficult to remove due to obstructions from straw and their small size, resulting in relatively poor iron slag removal efficiency and impacting feed product quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a feed raw material iron slag removal device, comprising a screen box, wherein bottom rods are fixedly installed at the four lower corners of the screen box, support rods are installed at the lower ends of the bottom rods, and bottom plates are installed at the lower ends of the support rods; a screen plate is fixedly installed on the lower inner side of the screen box; vibrators are symmetrically fixedly installed on both sides of the screen box; a plate electromagnet is symmetrically fixedly installed in the middle of the upper side of the screen box; the upper side and one side of the screen box are open; a discharge port is opened on the lower side of the screen box near the opening; a plate electromagnet is installed on the lower side of the screen box corresponding to the discharge port; connecting rods are fixedly installed on both sides of the plate electromagnet; the upper side of the connecting rods is bolted to the side of the screen box; and the plate electromagnet is inclined downwards towards the side away from the bottom rods.

[0007] The beneficial effects of this invention are as follows: it can screen out fine feed and iron filings from straw feed, and use plate electromagnet one to adsorb larger iron filings that are easily adsorbed from the straw feed, and plate electromagnet two to adsorb fine iron filings separately. Through the grading adsorption method after screening, the adsorption effect of iron filings in straw feed is greatly increased. Compared with the current method of directly setting a single plate electromagnet on the conveyor belt, its adsorption and removal effect of iron filings in feed is better, and it greatly improves the product quality of feed processing.

[0008] To enhance vibration damping effect;

[0009] As a further improvement to the above technical solution: vibration damping springs are fixedly installed between the base rod and the support rod.

[0010] The beneficial effects of this improvement are: to increase the vibration buffering effect and reduce the downward spread of vibration.

[0011] To facilitate the disassembly and replacement of the screen plate according to the needs of screening;

[0012] As a further improvement to the above technical solution: a placement rod is fixedly installed on both sides of the inner side of the sieve box corresponding to the sieve plate, the sieve plate is placed on the upper side of the placement rod, and the sieve plate and the placement rod are bolted together.

[0013] The beneficial effect of this improvement is that by removing the bolts, the screen plate can be easily disassembled and replaced according to the needs of screening.

[0014] For protection when adsorbing iron filings;

[0015] As a further improvement to the above technical solution: the lower side of the plate electromagnet one is bolted to a first iron protective shell, and the upper side of the plate electromagnet two is bolted to a second iron protective shell.

[0016] The beneficial effects of this improvement are: it can protect the surface of plate electromagnet one and plate electromagnet two when adsorbing iron filings, and can be directly disassembled and replaced after the iron protective shell one and iron protective shell two are damaged.

[0017] To increase the screening effect of straw feed and facilitate the removal of iron filings by plate electromagnets;

[0018] As a further improvement to the above technical solution: the inner side of the screen box is provided with a lever interleaved with the plate electromagnet one. The levers are respectively located on the side of the plate electromagnet one away from the plate electromagnet two. Each lever includes a shaft and a lever plate. The shaft is rotatably connected to the screen box. A motor is fixedly installed on one side of the screen box corresponding to each lever. The output end of each motor passes through the inner side of the screen box and is fixedly connected to the shaft. Lever plates are fixedly arranged equidistantly around the outer side of the shaft. When the lever plates rotate, they are close to the upper side of the screen plate.

[0019] The beneficial effects of this improvement are as follows: when the motor is started, the output end of the motor drives the agitator plate to rotate through the shaft. When the agitator plate rotates, it will turn the straw feed, which will increase the screening effect of the straw feed and make it easier for iron filings to be attracted away by the plate electromagnet.

[0020] In order to improve the stability of the device operation;

[0021] As a further improvement to the above technical solution: the bottom surface of the base plate is a rough, non-slip textured surface.

[0022] The beneficial effects of this improvement are as follows: the rough anti-slip texture on the bottom surface of the base plate increases the contact friction with the ground, effectively preventing horizontal displacement caused by vibration when the vibrator is working, thus improving the stability of the device operation.

[0023] To reduce hard scratches and wear on the surface of the screen plate;

[0024] As a further improvement to the above technical solution: the side of the actuating plate away from the shaft is made of rubber strips, and the rubber strips adhere to the upper side of the screen plate when rotating.

[0025] The beneficial effects of this improvement are as follows: the rubber strips of the agitator are soft and elastic, which can reduce the hard scratching and wear on the screen plate surface when rotating and turning the feed, thus extending the service life of the screen plate. The design of sticking to the screen plate can more fully turn the feed layer close to the screen, making it easier for fine iron filings to be exposed and fall through the screen, further improving the screening and iron filings separation effect.

[0026] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0034] like Figures 1-5As shown: A feed raw material iron slag removal device includes a screen box 1. Base rods 2 are fixedly installed at the four lower corners of the screen box 1. Support rods 3 are installed at the lower ends of the base rods 2, and a base plate 4 is installed at the lower ends of the support rods 3. A screen plate 5 is fixedly installed on the lower inner side of the screen box 1. Vibrators 6 are symmetrically fixedly installed on both sides of the screen box 1. A plate electromagnet 7 is symmetrically fixedly installed in the middle of the upper side of the screen box 1. The upper side and one side of the screen box 1 are open. A discharge port 8 is opened on the lower side of the screen box 1 near the opening. A plate electromagnet 10 is installed on the lower side of the screen box 1 corresponding to the discharge port 8. Connecting rods 9 are fixedly installed on both sides of the plate electromagnet 10. The upper side of the connecting rods 9 is screwed to the side of the screen box 1. The plate electromagnet 210 is fixedly connected and tilted downwards away from the bottom rod 2. This allows it to screen out fine feed and iron filings from the straw feed. The plate electromagnet 17 adsorbs larger, easily removable iron filings from the straw feed, while the plate electromagnet 210 separately adsorbs fine iron filings. This grading adsorption method after screening significantly increases the adsorption effect on iron filings from the straw feed. Compared to the current method of directly installing a single plate electromagnet on the conveyor belt, this method has a better adsorption and removal effect on iron filings in the feed, greatly improving the quality of the processed feed. Vibration damping springs 11 are fixedly installed between the bottom rod 2 and the support rod 3 to increase vibration buffering and reduce the downward spread of vibration. The inner sides of the screen box 1 are corresponding to... A screen plate 5 is fixedly provided with a placement rod 51. The screen plate 5 is placed on the upper side of the placement rod 51. The screen plate 5 and the placement rod 51 are bolted together. By removing the bolts, the screen plate 5 can be easily disassembled and replaced according to the needs of screening. The lower side of the plate electromagnet 1 7 is bolted with an iron protective shell 71, and the upper side of the plate electromagnet 2 10 is bolted with an iron protective shell 2 101. This is used to protect the plates when adsorbing iron filings and to prevent the iron filings from directly scratching the surfaces of the plate electromagnet 1 7 and the plate electromagnet 2 10. The iron protective shells 71 and 2 101 can be directly disassembled and replaced if damaged. The inner side of the screen box 1 is provided with a lever 13, which is staggered with the plate electromagnet 1 7. The lever 13 is divided into... The actuating rod 13 is located on the side of the plate electromagnet 7 away from the plate electromagnet 10. The actuating rod 13 includes a shaft 131 and an actuating plate 132. The shaft 131 is rotatably connected to the screen box 1. A motor 12 is fixedly mounted on one side of the screen box 1 corresponding to the actuating rod 13. The output end of each motor 12 passes through the inside of the screen box 1 and is fixedly connected to the shaft 131. The actuating plates 132 are equidistantly fixed around the outer side of the shaft 131. When the actuating plates 132 rotate, they are close to the upper side of the screen plate 5. The bottom surface of the base plate 4 is a rough, anti-slip textured surface. This rough, anti-slip textured surface increases the contact friction with the ground, effectively preventing horizontal displacement caused by vibration during the operation of the vibrator 6, thus improving the stability of the device's operation.The side of the actuating plate 132 away from the shaft 131 is made of rubber strips. When the rubber strips rotate, they adhere to the upper side of the screen plate 5. The rubber strips of the actuating plate 132 are soft and elastic, reducing hard scraping and wear on the surface of the screen plate 5 when rotating and turning the feed, thus extending the service life of the screen plate. The design of adhering to the screen plate 5 allows for more thorough turning of the feed layer close to the screen, making it easier for fine iron filings to be exposed and fall through the screen, further improving the screening and iron filings separation effect.

[0035] Working principle and usage process of this utility model:

[0036] In use, straw feed is fed into the upper side of the sieve box 1, away from the side of the plate electromagnet 2 10. After the straw feed is fed into the upper side of the screen plate 5, the vibrator 6 drives the screen plate 5 to vibrate continuously through the sieve box 1, continuously vibrating the side of the straw feed with the opening facing the side. Fine feed and fine iron filings in the straw feed will fall through the screen plate 5 to the bottom of the inner side of the sieve box 1. When the straw feed passes under the plate electromagnet 7 on the upper side of the screen plate 5, larger iron filings will be attracted to the surface of the plate electromagnet 7. The loose feed will fall onto the upper side of the plate electromagnet 2 10 when it is discharged through the discharge port 8. The fine iron filings will be directly attracted and left by the plate electromagnet 2 10. The fine feed will follow the plate electromagnet 2 10. As the straw falls, it is discharged from the side opening of the sieve box 1, mixing with the fine feed below. At this time, a conveyor belt device is set below the plate electromagnet 2 10 to convey it out together. Through the above structure, the fine feed and fine iron filings in the straw feed can be screened out downwards. The plate electromagnet 1 7 adsorbs the larger iron filings in the straw feed that are easily adsorbed, while the plate electromagnet 2 10 is used to adsorb the fine iron filings separately. Through the grading adsorption after screening, the adsorption effect of iron filings in the straw feed is greatly increased. Compared with the current method of directly setting a single plate electromagnet on the conveyor belt, its adsorption and removal effect of iron filings in the feed is better, which greatly improves the product quality of feed processing.

[0037] In addition, damping springs 11 are fixedly installed between the bottom rod 2 and the support rod 3. These damping springs 11 are used to increase vibration buffering and reduce the downward spread of vibration. Furthermore, placement rods 51 are fixedly installed on both sides of the inner side of the screen box 1 corresponding to the screen plate 5. The screen plate 5 is placed on the upper side of the placement rods 51, and the screen plate 5 and placement rods 51 are bolted together. The screen plate 5 can be easily disassembled and replaced according to the needs of screening by removing the bolts. Additionally, an iron protective shell 71 is bolted to the lower side of the plate electromagnet 7. The upper side of magnet 210 is bolted with an iron protective shell 2101, which is used to protect the surface of plate electromagnet 17 and plate electromagnet 210 when adsorbing iron filings. The iron protective shell 171 and iron protective shell 2101 can be directly disassembled and replaced after damage. In addition, when the motor 12 is started, the output end of the motor 12 drives the agitator plate 132 to rotate through the shaft 131. When the agitator plate 132 rotates, it will turn the straw feed, increase the screening effect of the straw feed and make it easier for the iron filings to be attracted away by plate electromagnet 17.
