Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, specifically to an integrated magnetic separation and iron removal device. Background Technology

[0002] In the soybean meal feed production industry, product quality is of paramount importance. However, during the production process, soybean meal is easily mixed with iron slag and other iron impurities, which not only affect feed quality but may also harm the health of farmed animals. Currently, magnetic removal of iron is commonly used to remove iron impurities from feed, which can effectively remove iron impurities and ensure the purity and safety of soybean meal feed.

[0003] Utility model patent CN202321487444.3 discloses a magnetic separation device for feed production. This device includes a vibrating screen, a diversion mechanism, and several magnetic separation screen plates. The vibrating screen is connected to a first vibration mechanism to drive it to vibrate horizontally. The diversion mechanism is positioned below the vibrating screen and below each diversion channel of the several magnetic separation screen plates. Each magnetic separation screen plate is inclined and contains an electromagnet. This magnetic separation device for feed production uses the vibrating screen to remove large particles. Simultaneously, the vibrating screen, through vibration, separates agglomerated coarse powdery materials into bulk materials, which then enter the diversion mechanism below. After being divided into multiple material flows, these flows enter multiple magnetic separation screen plates, reducing the workload of individual magnetic separation screen plates. This device is suitable for magnetic separation of large flow rates of materials.

[0004] Due to the long-term effect of the magnetic field, the magnetic separator screen plate will become magnetic, resulting in some iron impurities remaining on the magnetic separator screen plate. This makes it difficult to clean these iron impurities, making it easy for the iron impurities on the magnetic separator screen plate to mix into the feed after demagnetization, and also making it inconvenient to clean the magnetic separator screen plate. In view of this, we propose an integrated magnetic separation iron removal device. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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. Example

[0028] Please see Figures 1-4 and Figure 6 This utility model provides a technical solution:

[0029] The integrated magnetic separation and iron removal device includes a body 1, which is inclined at the front and high at the back. A hopper 2 for feeding materials is set at the top of the inclined body 1. Connecting plates 22 are fixed to the left and right end faces of the hopper 2. The bottom end of the connecting plates 22 is fixed to the body 1, thereby fixing the hopper 2 to the body 1. A slag collection plate 3 is placed on the top of the body 1. The bottom end of the hopper 2 is provided with a discharge end 21, with the bottom end of the discharge end 21 facing the top surface of the slag collection plate 3. This design allows the material to slide naturally from the hopper 2 onto the slag collection plate 3 by means of the inclined slope of the body 1, realizing automatic material conveying and preparing for the subsequent magnetic separation and iron removal process, effectively improving the convenience and continuity of material processing.

[0030] Furthermore, the space between the body 1 and the slag collection plate 3 is filled with several magnetic strips 13, and the bottom surface of the slag collection plate 3 abuts against the top surface of the magnetic strips 13. Under the action of the magnetic strips 13, the material falling onto the slag collection plate 3 can be drawn out by the magnetic force and the iron slag is attached to the surface of the slag collection plate 3, thereby achieving the purpose of magnetic separation and iron removal.

[0031] In addition, the top surface of the body 1 is provided with several grooves 11 with V-shaped cross sections that pass through the front and rear ends of the body 1. The bottom of the groove 11 is provided with a slot 111, and the magnetic strip 13 is embedded and fixed in the slot 111. The magnetic strip 13 is installed on the body by embedding it in the slot 111. This structure ensures the stability of the magnetic strip 13 installation, prevents it from shifting or shaking during operation, maintains a stable magnetic field, and ensures the stability of the iron removal effect.

[0032] It is worth noting that several grooves 11 are horizontally distributed along the top surface of the machine body 1. The V-shaped design of the grooves 11 increases the bottom area of ​​the grooves 11, thereby increasing the number of magnetic strips 13 that can be installed and improving the adsorption effect of iron slag. The top of the slag collecting plate 3 is provided with several guide grooves 31. The cross-section of the slag collecting plate 3 is also V-shaped. The number and position of the guide grooves 31 correspond one-to-one with the number and position of the grooves 11. This ensures that when the slag collecting plate 3 is placed on the machine body 1, the protruding bottom surface of the slag collecting plate 3 can fully contact the magnetic strips 13, increasing the magnetic attraction effect and significantly increasing the contact area between the material and the slag collecting plate 3. As a result, under the action of the magnetic strips 13, the iron slag in the material is efficiently adsorbed onto the surface of the slag collecting plate 3, improving the iron removal efficiency.

[0033] It is worth noting that positioning holes 32 are provided on both the left and right sides of the front end of the slag collection plate 3, and blocking columns 12 are fixed on both the left and right sides of the front end of the top of the machine body 1. When the slag collection plate 3 is placed on the machine body 1, the blocking columns 12 pass through the positioning holes 32, so that the slag collection plate 3 is stopped at the top of the machine body 1 by the blocking columns 12, preventing the slag collection plate 3 from sliding off along the inclined top surface of the machine body 1.

[0034] Furthermore, support legs 14 are fixedly installed at the four corners of the bottom of the machine body 1. The support legs 14 make the device stable. A material discharge guide plate 15 is provided at the front end of the machine body 1. The material discharge guide plate 15 is inclined with the left side lower and the right side higher. The cross-section of the material discharge guide plate 15 is U-shaped. The material discharge guide plate 15 is fixed between the two support legs 14 located at the front end of the machine body 1. The material discharge guide plate 15 can guide the material that slides down to the front end of the slag collection plate 3 into the material discharge guide plate 15 for collection, which is convenient for subsequent collection and processing.

[0035] Furthermore, the longitudinal length of the slag collection plate 3 is greater than that of the machine body 1, and the front end of the slag collection plate 3 protrudes beyond the front end of the machine body 1. This prevents the material after magnetic separation from falling onto the machine body 1 from the front end of the slag collection plate 3, thus avoiding material contamination of the machine body 1 and reducing the cleaning operations required by the operators. Handles 33 are fixed to both the left and right edges of the top surface of the slag collection plate 3. The handles 33 facilitate the movement and cleaning of the slag collection plate 3 by the operators, improving the ease of maintenance.

[0036] In this embodiment, the integrated magnetic separation and iron removal device first pours the feed material to be magnetically separated into the hopper 2, allowing the material to fall along the discharge end 21 to the rear end of the slag collection plate 3. Then, under the action of gravity, the material slides down along multiple guide grooves 31 on the surface of the slag collection plate 3. At this time, under the action of the magnetic strips 13, the iron slag in the material is attracted by the magnetic strips 13 to the bottom surface of the guide grooves 31, achieving the purpose of magnetic separation and iron removal. Due to the setting of multiple guide grooves 31, the number of magnetic strips 13 is increased, thereby increasing the magnetic attraction efficiency. Finally, when it is necessary to process the iron slag adsorbed on the surface of the slag collection plate 3, the operator can lift the slag collection plate 3 upward by the handle 33 to detach the slag collection plate 3 from the machine body 1, so that the iron slag can be easily removed, preventing the accumulated iron slag from affecting the subsequent magnetic separation and iron removal of the material. Example

[0037] like Figure 5 As shown, a material-pushing flap 23 is provided inside the discharge end 21. The material-pushing flap 23 is mounted on a rotating shaft 231. The material-pushing flap 23 is composed of multiple rectangular thin plates, which are fixed to a shaft in a centrally symmetrical manner. By allowing the rotating shaft 231 to pass through the shaft, the discharge end 21 can be penetrated by the rotating shaft 231, allowing the material-pushing flap 23 to be installed inside the discharge end 21. A speed-adjustable motor 232 is provided at the end of the rotating shaft 231. By adjusting the rotation speed of the motor 232, the rotation speed of the material-pushing flap 23 can be adjusted, thereby flexibly controlling the falling speed of the material from the hopper 2 to the slag collection plate 3. By precisely controlling the rotation speed of the material-pushing flap 23, the production process requirements of different materials can be effectively met, enhancing the versatility and adaptability of the equipment.

[0038] It is worth noting that the electric motor 232 involved in this utility model is a conventional technology and will not be described in detail here.
