Description

Technical Field

[0001] The present application relates to the field of separation mechanisms, and in particular to an automatic iron foreign body separation mechanism for a soybean meal crusher. Background Art

[0002] Soybean meal is a series of by-products produced during the soybean oil refining process. Since soybean meal is rich in nutrients such as protein and amino acids, it can be used as the main protein feed for animals after processing.

[0003] In the process of processing soybean meal into feed, the soybean meal needs to be crushed by a crusher (usually a hammer crusher). During the early stages of oil refining and transportation, soybean meal is inevitably mixed with iron foreign objects such as gaskets, wires or bolts due to wear of mechanical equipment or falling parts. In order to prevent iron foreign objects from entering the crusher with soybean meal and causing damage to the internal components of the crusher, strong magnetic plates are usually installed on both sides of the crusher's feed port to form a magnetic separation mechanism. The strong magnetic plates are used to adsorb iron foreign objects mixed in the soybean meal to limit the entry of iron foreign objects into the crusher.

[0004] Regarding the above-mentioned related technologies, although the setting of the strong magnetic plate can absorb and screen out the iron foreign matter mixed in the soybean meal, it is necessary to manually remove the strong magnetic plate from the crusher regularly to clean the iron foreign matter adsorbed by it. The operation is inconvenient and the efficiency is low. Therefore, there is room for improvement. Summary of the invention

[0005] In order to timely screen out and separate the iron foreign matter mixed in the soybean meal, limit the iron foreign matter from entering the crusher with the soybean meal, and facilitate the cleaning of the iron foreign matter; the present application provides an automatic iron foreign matter separation mechanism for a soybean meal crusher.

[0006] The present application provides an automatic iron foreign body separation mechanism for a soybean meal crusher, which adopts the following technical solution:

[0007] An automatic iron foreign body separation mechanism for a soybean meal crusher, comprising a separation box, a magnetic separation mechanism and a collection mechanism;

[0008] The top of the separation box is communicated with the discharge end of a soybean meal conveying device used in conjunction with the automatic iron foreign matter separation mechanism, and the bottom of the separation box is communicated with the feed end of a soybean meal crusher used in conjunction with the automatic iron foreign matter separation mechanism;

[0009] The magnetic separation mechanism comprises two electromagnet plates, which are respectively supported on opposite sides of the inner cavity of the separation box, and the two electromagnet plates are staggered, and both of the electromagnet plates extend downwardly and obliquely toward the bottom of the separation box;

[0010] The collecting mechanism is located below the magnetic separation mechanism, and includes a collecting trough and a sliding drive. The collecting trough is horizontally slidably plugged into the separation box, and the sliding drive is drivingly connected to the collecting trough to drive the collecting trough to slide in the horizontal direction.

[0011] By adopting the above technical solution, before the soybean meal conveying equipment inputs the material into the separation box, the sliding drive component drives the collecting tank to slide out of the separation box, so that the inner cavity of the separation box is connected with the soybean meal conveying equipment and the crusher respectively, and the electromagnetic iron plate is energized so that it can absorb iron foreign matter; subsequently, the soybean meal crusher inputs the soybean meal to be crushed into the separation box through the top of the separation box, and the soybean meal entering the separation box flows downward along the two electromagnetic iron plates, and flows into the crusher through the bottom of the separation box for crushing; during this period, when the soybean meal flows through the two electromagnetic iron plates, the electromagnetic iron plates are used to absorb the iron foreign matter mixed in the soybean meal, so as to achieve the purpose of removing the iron foreign matter. Separate from the soybean meal; when subsequently cleaning the iron foreign matter adsorbed on the electromagnet plate, first drive the collecting trough to slide into the inner cavity of the separation box and be located under the two electromagnet plates through the sliding drive component, and then cut off the power to the electromagnet so that the iron foreign matter originally adsorbed on the electromagnet plate can fall into the collecting trough, and finally drive the collecting trough to slide out of the separation box through the sliding drive component to clean the iron foreign matter out of the separation box, thereby realizing the cleaning of the iron foreign matter adsorbed on the electromagnet plate; compared with the traditional strong magnetic plate structure, it is conducive to timely separation of iron foreign matter mixed in the soybean meal, and it is convenient to clean the iron foreign matter adsorbed on the magnetic separation mechanism.

[0012] Preferably, the magnetic separation mechanism also includes two first connecting plates; the two first connecting plates are detachably connected to the opposite sides of the separation box, and the two electromagnet plates are respectively connected to the opposite sides of the two first connecting plates. The opposite sides of the separation box are provided with first installation openings corresponding to the electromagnet plates, and the electromagnet plates extend into the inner cavity of the separation box through the corresponding first installation openings.

[0013] By adopting the above technical solution, the two electromagnetic plates can be firmly supported on the opposite sides of the inner cavity of the separation box; at the same time, they can be detachably installed on the separation box through the first connecting plate. When the electromagnetic plate fails or is damaged later, the first connecting plate can be removed from the separation box to facilitate the repair or replacement of the electromagnetic plate.

[0014] Preferably, one side of the electromagnet plate close to the corresponding first connecting plate is horizontally hinged to the corresponding first connecting plate, and the first connecting plate is provided with a plurality of flip cylinders corresponding to the electromagnet plate, and the opposite ends of the flip cylinders are horizontally hinged to the first connecting plate and the bottom of the electromagnet plate respectively.

[0015] By adopting the above technical solution, the corresponding electromagnet plate can be driven to swing by turning the cylinder to drive its own piston rod to extend and retract, which is beneficial to adjust the discharge gap between the two electromagnet plates through the swing of the two electromagnet plates, thereby realizing the adjustment of the soybean meal discharge speed at the bottom of the separation box.

[0016] Preferably, a dispersion mechanism is further provided in the separation box, and the dispersion mechanism is located above the magnetic separation mechanism; the dispersion mechanism includes a plurality of horizontally arranged impact rods.

[0017] By adopting the above technical solution, soybean meal is prone to agglomeration due to its own viscosity, resulting in the iron foreign matter being wrapped, which affects the subsequent adsorption of the iron foreign matter by the electromagnetic iron plate. Through the setting of a number of impact rods, the soybean meal that subsequently enters the separation box can first collide with the impact rods and disperse before continuing to flow downward. The impact rods are used to break up the soybean meal, so that some of the agglomerated soybean meal can be better separated, which is conducive to the subsequent electromagnetic iron plate to better adsorb the iron foreign matter mixed in the soybean meal.

[0018] Preferably, the dispersion mechanism also includes a second connecting plate, which is detachably connected to the outside of the separation box; one end of the impact rod is rotatably connected to the second connecting plate, and the second connecting plate is provided with a plurality of rotary driving members corresponding to the impact rods, and the rotary driving members are drivingly connected to the corresponding impact rods for driving the corresponding impact rods to rotate.

[0019] By adopting the above technical solution, the corresponding impact rod is driven to rotate by the rotary driving member of the second connecting plate. On the one hand, the rotating impact rod can better enter the soybean meal in the separation box for striking, which is beneficial for better dispersion of the agglomerated soybean meal. On the other hand, it is beneficial for buffering the impact of the continuously falling soybean meal on the impact rod, and reducing the wear of the impact rod due to the scouring of the soybean meal.

[0020] Preferably, a plurality of air knives are further provided in the separation box, wherein the air knives are located between the dispersion mechanism and the magnetic separation mechanism, and the air outlets of the air knives are vertically arranged downward.

[0021] By adopting the above technical solution and setting a plurality of wind knives, when the soybean meal flows through the separation box, the compressed airflow is continuously blown toward the two electromagnetic iron plates through the wind knives, thereby reducing the accumulation of the soybean meal flowing through the electromagnetic iron plates on the electromagnetic iron plates due to its own viscosity or being blocked by iron foreign matter adsorbed on the electromagnetic iron plates, which is conducive to the soybean meal flowing through the electromagnetic iron plates more smoothly.

[0022] Preferably, the plurality of wind knives correspond one-to-one to the plurality of impact rods, and the wind knives are all located below the corresponding impact rods.

[0023] By adopting the above technical solution, by supporting the wind knife at the bottom of the corresponding impact rod, the impact rod can be used to shield and protect the wind knife, which is helpful to reduce the situation where the wind knife is easily worn due to direct impact of soybean meal.

[0024] Preferably, a material baffle plate is supported on one side of the first connecting plate toward the inner cavity of the separation box, the material baffle plate is located above the hinged side of the electromagnet plate and covers the hinged side of the electromagnet plate, and the material baffle plate extends obliquely downward in a direction away from the first connecting plate.

[0025] By adopting the above technical solution, the gap between the hinged side of the electromagnet plate and the first connecting plate is blocked by the material blocking plate, which is helpful to reduce the situation where some soybean meal entering the separation box later is stuck in the hinged side of the electromagnet plate, causing cleaning difficulties.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Through the arrangement of the magnetic separation mechanism and the collecting mechanism inside the separation box, when the soybean meal flows through the two electromagnet plates of the magnetic separation mechanism, the two electromagnet plates can adsorb and fix the iron foreign matter mixed in the soybean meal, so as to screen out the iron foreign matter from the soybean meal; when subsequently cleaning the iron foreign matter screened out by the magnetic separation mechanism, the sliding drive member at the collecting mechanism drives the collecting trough to slide into the air separator, and at the same time, the two electromagnet plates are powered off, so that the iron foreign matter on the two electromagnet plates can slide into the collecting trough, and then the sliding drive member drives the collecting trough to drive the iron foreign matter to slide out of the separation box, thereby realizing automatic cleaning of the iron foreign matter.

[0028] 2. Through the setting of the dispersion mechanism, when the soybean meal flows into the separation box, it can first contact with a number of rotating impact rods of the dispersion mechanism, and the rotating impact rods are used to drive the agglomerated soybean meal to disperse, so that the soybean meal can be spread more evenly on the electromagnet plate, which is conducive to the electromagnet plate to better adsorb the iron debris mixed in the soybean meal.

[0029] 3. By arranging a number of wind knives between the dispersion mechanism and the magnetic separation mechanism, and making the wind knives located under the corresponding impact rods, when the soybean meal flows through the separation box, the wind knives continuously blow compressed air toward the two electromagnetic plates, which is conducive to the soybean meal sliding off the electromagnetic plates quickly and reducing the accumulation of soybean meal on the electromagnetic plates due to the stickiness of the soybean meal or the iron foreign matter adsorbed on the electromagnetic plates.

[0038] The following is combined with Figure 1-6 This application is described in further detail.

[0039] The present application embodiment discloses an automatic iron foreign body separation mechanism for a soybean meal crusher, referring to Figure 1 and Figure 2 , including a separation box 2, the top of which is connected to a soybean meal conveying device for cooperating with an automatic separation mechanism for iron foreign matter; the bottom of the separation box 2 is connected to a feed port of a crusher 1 for cooperating with an automatic separation mechanism for iron foreign matter; a magnetic separation mechanism 3 and a collecting mechanism are sequentially arranged in the separation box 2 from top to bottom.

[0040] Reference Figure 2 and Figure 3 The magnetic separation mechanism 3 includes two electromagnetic plates 30 and two first connecting plates 31; the two electromagnetic plates 30 are respectively supported on opposite sides of the inner cavity of the separation box 2; the two electromagnetic plates 30 are staggered, and the two electromagnetic plates 30 are inclined downward toward the bottom of the separation box 2, and the projections of the two electromagnetic plates 30 on the horizontal plane are intersected, which is conducive to the subsequent soybean meal entering the separation box 2 to flow through the two electromagnetic plates 30 better, and then it is conducive to the two electromagnetic plates 30 to better adsorb and screen out iron foreign matter mixed in the soybean meal.

[0041] Reference Figure 2 and Figure 3 , the two first connecting plates 31 are connected to the opposite outer sides of the separation box 2 by bolts; the two electromagnetic iron plates 30 are respectively located on the opposite sides of the two first connecting plates 31; the corresponding electromagnetic iron plates 30 on the opposite sides of the separation box 2 are provided with first installation openings 21; the electromagnetic iron plates 30 are extended into the inner cavity of the separation box 2 through the corresponding first installation openings 21; through the above settings, the two electromagnetic iron plates 30 are firmly supported on the opposite sides of the inner cavity of the separation box 2; at the same time, when the electromagnetic iron plate 30 fails or needs to be replaced later, the first connecting plate 31 can be removed from the separation box 2 to move the electromagnetic iron plate 30 out of the inner cavity of the separation box 2, so as to facilitate the maintenance or replacement of the electromagnetic iron plate 30.

[0042] Reference Figure 3 and Figure 4 , the side of the electromagnet plate 30 close to the corresponding first connecting plate 31 is horizontally hinged on the first connecting plate 31; the side of the first connecting plate 31 facing the inner cavity of the separation box 2 is also provided with a plurality of flip cylinders 32 corresponding to the electromagnet plate 30, one end of the flip cylinder 32 is horizontally hinged to the first connecting plate 31, and the other end of the flip cylinder 32 is horizontally hinged to the bottom of the electromagnet plate 30, and the rotation axis at both ends of the flip cylinder 32 is arranged parallel to the rotation axis of the hinged side of the electromagnet plate 30. Through the above arrangement, in the subsequent actual use process, the electromagnet plate 30 can be driven to swing by the flip cylinder 32 to adjust the inclination angle of the two electromagnet plates 30, thereby realizing the adjustment of the soybean meal discharge speed at the bottom of the separation box 2.

[0043] The first connecting plate 31 is also connected to a baffle plate 311 on the side facing the separation box 2. In the present embodiment, the baffle plate 311 is made of iron sheet. The baffle plate 311 is located above the hinged side of the electromagnet plate 30 and covers the hinged side of the electromagnet plate 30. The baffle plate 311 is used to shield and protect the hinged side of the electromagnet plate 30, so as to limit the subsequent soybean meal entering the separation box 2 from being stuck in the hinged side of the electromagnet plate 30, and reduce the situation that the soybean meal is easy to rot and mildew after being stuck in the hinged side of the electromagnet plate 30 due to difficulty in cleaning. The baffle plate 311 is tilted downward in a direction away from the corresponding first connecting plate 31, so as to facilitate the soybean meal that falls on the baffle plate 311 to slide from the baffle plate 311 to the electromagnet plate 30.

[0044] Reference Figure 2 and Figure 5The collecting mechanism includes a collecting tank 4 and a sliding drive member, and the separation box 2 is provided with a socket 23 corresponding to the collecting tank 4; the collecting tank 4 is slidably plugged into the separation box 2 through the socket 23; the sliding drive member includes two sliding cylinders 41 arranged horizontally, and the two sliding cylinders 41 are respectively supported at both ends of the separation box 2; the piston rods of the two sliding cylinders 41 are connected to the side of the collecting tank 4 away from the separation box 2 through the connecting block, so that the sliding drive member is driven to be connected to the collecting tank 4, and then the sliding cylinder 41 drives its own piston rod to extend and retract, so as to drive the collecting tank 4 to slide in the horizontal direction.

[0045] Before the soybean meal conveying device conveys the soybean meal to the separation box 2, the two sliding cylinders 41 drive the collecting trough 4 to slide out of the separation box 2 and block the socket 23, so that the soybean meal subsequently output by the soybean meal conveying device can fall into the crusher 1 through the separation box 2. When it is necessary to clean the iron foreign matter adsorbed on the electromagnet plate 30, the two sliding cylinders 41 drive the collecting trough 4 to slide into the separation box 2 to block the inner cavity of the separation box 2, and then the two electromagnets are powered off, so that the iron foreign matter originally adsorbed on the electromagnet can slide into the collecting trough 4 located below the two electromagnet plates 30, so as to realize the cleaning and automatic collection of the iron foreign matter adsorbed on the electromagnet plate 30.

[0046] Reference Figure 5 and Figure 6 The inner cavity of the separation box 2 is also provided with a dispersion mechanism 5, which is located above the magnetic separation mechanism 3, and the dispersion mechanism 5 includes a second connecting plate 52; the separation box 2 is provided with a second installation port 22 corresponding to the second connecting plate 52, and the second connecting plate 52 is connected to the outer side of the separation box 2 by bolts, and the second connecting plate 52 blocks the second installation port 22; a plurality of impact rods 51 are horizontally arranged on the side of the second connecting plate 52 facing the separation box 2; one end of the impact rod 51 away from the second connecting plate 52 extends to the inner cavity of the separation box 2 through the second installation port 22; a plurality of rotary driving members are also arranged on the side of the second connecting plate 52 away from the separation box 2 corresponding to the plurality of impact rods 51, specifically, the rotary driving member is a rotary motor 54, the rotary motor 54 is installed on the second connecting plate 52 through a bracket 53, and the output end of the rotary motor 54 is coaxially connected to the corresponding end of the impact rod 51 through a coupling, so that the rotary driving member is driven and connected to the corresponding impact rod 51.

[0047] When the soybean meal to be crushed is subsequently input into the separation box 2 through the soybean meal conveying equipment, the corresponding impact rod 51 is driven to rotate by the rotary motor 54. On the one hand, the rotating impact rod 51 is used to hit the soybean meal that subsequently enters the separation box 2, which is conducive to better dispersion of the soybean meal that adheres to the block, and then helps the soybean meal that enters the separation box 2 to be more evenly scattered onto the electromagnetic plate 30, so that the electromagnetic plate 30 can better adsorb the iron foreign matter wrapped in the soybean meal; on the other hand, the rotation of the impact rod 51 is conducive to buffering the impact of the soybean meal on the impact rod 51, and then helps to reduce the wear of the impact rod 51 due to the continuous impact of the soybean meal.

[0048] The second connecting plate 52 is also horizontally mounted with a plurality of wind knives 6, which are all extended to the inner cavity of the separation box 2 through the second mounting opening 22; the wind knives 6 are located between the magnetic separation mechanism 3 and the impact rod 51, and the air outlets of the wind knives 6 are all vertically arranged downward. By setting a plurality of wind knives 6, the wind knives 6 are subsequently used to continuously blow compressed air toward the two electromagnetic plates 30 to accelerate the downward sliding of the soybean meal on the electromagnetic plates 30, and reduce the situation where the soybean meal is accumulated on the electromagnetic plates 30 due to its own viscosity or being blocked by iron foreign matter adsorbed on the electromagnetic plates 30. In other embodiments, the wind knives 6 can also be replaced by air ducts.

[0049] The plurality of wind knives 6 are respectively located under the plurality of impact rods 51 , and the impact rods 51 are used to shield and protect the wind knives 6 , which is helpful to reduce the situation where the wind knives 6 are easily damaged by direct impact of soybean meal when the soybean meal is continuously input into the separation box 2 .

[0050] The implementation principle of the embodiment of the present application is:

[0051] Before the soybean meal to be processed is crushed by the crusher 1, the electromagnet plate 30 is energized so that it can absorb iron foreign matter; the collecting tank 4 is driven to slide out of the separation box 2 and the socket 23 on the outside of the separation box 2 is blocked by two sliding cylinders 41; the corresponding impact rod 51 is driven to rotate by the rotary motor 54; and at the same time, the compressed air flow is continuously blown toward the two electromagnet plates 30 of the magnetic separation mechanism 3 through the wind knife 6.

[0052] When the soybean meal to be processed is processed by the crusher 1, the soybean meal is continuously fed into the separation box 2 through the soybean meal conveying equipment. After entering the separation box 2, the soybean meal first contacts the rotating impact rod 51, then falls onto the two electromagnet plates 30 of the magnetic separation mechanism 3, and then continues to slide downward through the two electromagnet plates 30, and finally flows into the crusher 1 through the bottom of the separation box 2 for crushing. When the soybean meal flows through the two electromagnet plates 30, the two electromagnet plates 30 adsorb the iron foreign matter wrapped in the soybean meal, so as to automatically separate the iron foreign matter from the soybean meal, and limit the subsequent iron foreign matter from entering the crusher 1 together with the soybean meal.

[0053] When cleaning the iron foreign matter adsorbed on the electromagnetic plate 30, the two sliding cylinders 41 are used to drive the collecting trough 4 to slide into the separation box 2 and seal the inner cavity of the separation box 2, and then the two electromagnetic plates 30 are powered off so that the iron foreign matter originally adsorbed on the electromagnetic plate 30 can slide into the collecting trough 4; finally, the two sliding cylinders 41 are used to drive the collecting trough 4 to drive the iron foreign matter to slide out of the separation box 2, thereby realizing automatic cleaning of the iron foreign matter.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
