Description

Technical Field

[0001] This invention relates to the field of crop cell wall breaking and dust removal, specifically a crop cell wall breaking and dust removal device. Background Technology

[0002] Crop cell wall breaking refers to the business activity of converting raw grains into semi-finished grains through processing. It is often used in the manufacture of yeast. Before the crop cell wall is broken, the crop often needs to be dried. During the drying process, the crop often contains impurities such as dust, stones or metal.

[0003] Existing technologies can effectively remove obvious stones or metal impurities from crops, but they often cannot completely remove small stones or metal impurities contained in crops. Secondly, the process of breaking down the cell walls of crops often leads to excessive dust, which affects the health of the personnel involved in the process. Furthermore, the degree of cell wall breaking often varies, and the entire batch of broken crops often needs to be reinforced due to incomplete cell wall breaking, which is time-consuming and labor-intensive. Summary of the Invention

The dust and impurities collected in the collection box 2 can be effectively cleaned by opening the sealing cover 3.

[0036] As an optimized technical solution of the present invention, a rolling chamber 19 is provided at the center of the inner top of the housing 1. Two rolling rollers 16 are rotatably connected inside the rolling chamber 19, located on both sides of the center of the rolling chamber 19. An electromagnet 27 is embedded in the center of the inner part of the rolling roller 16. The electromagnet 27 is electrically connected to a battery 12. The electromagnet 27 penetrates through one side wall of the housing 1. One end of the electromagnet 27 penetrating through the side wall of the housing 1 is fixedly connected to a mounting frustum 11. The battery 12 is embedded in the mounting frustum 11. An embedding groove is provided on the mounting frustum 11. A cover is provided at the end of the embedding groove away from the electromagnet 27 to seal the battery 12. The magnetic poles of the electromagnet 27 can be adjusted by reversing the positive and negative terminals of the battery 12 with the terminals of the electromagnet 27, thereby achieving the purpose of adjusting the magnetic direction of the electromagnet 27. This technology is common knowledge and will not be disclosed in detail here.

[0037] As a technical optimization of the present invention, the side wall of the rolling roller 16 is provided with multiple sliding grooves 26, which are equidistantly arranged on the rolling roller 16. A magnetic plate 32 is slidably connected within each sliding groove 26. The magnetic plate 32 is adapted to an electromagnet 27. A rolling block 25 is fixedly connected to the center of the side of the magnetic plate 32 away from the electromagnet 27. The rolling block 25 penetrates the side wall of the rolling roller 16 and is slidably sleeved with the side wall of the rolling roller 16. The rolling blocks 25 on two rolling rollers 16 mesh with each other. The output shaft of a drive motor 8 is fixedly connected to the end of one rolling roller 16 away from the mounting frustum 11. A mounting plate 13 is fixedly connected to the bottom of the drive motor 8 and is fixedly connected to the side wall of the housing 1. The magnetic poles of the magnetic plate 32 are fixed, while the magnetic poles of the electromagnet 27 can be adjusted via the terminals of the battery 12. Therefore, the magnetic plate 32 and the electromagnet 27 can switch between "like poles repel" and "opposite poles attract".

[0038] As a technical optimization of the present invention, the top center of the crushing chamber 19 is connected to the bottom of the feed hopper 9, and the bottom center of the crushing chamber 19 is connected to the receiving chamber 20. The bottom wall plate of the receiving chamber 20 is provided with an inclined groove for material discharge. The separating chamber 23 is opened on the bottom of the housing 1 near the dust collector bag 6. The receiving chamber 20 and the separating chamber 23 are connected, and the connection point is located at the top of the separating chamber 23. The top of the separating chamber 23 away from the receiving chamber 20 is connected to a rectangular air outlet pipe 18. The dust collector bag 6 is fixedly connected to the end of the rectangular air outlet pipe 18 away from the separating chamber 23. The rectangular air outlet pipe 18 is provided with a clamping groove, and the input end of the dust collector bag 6 is clamped in the clamping groove. The detachable dust collector bag 6 is a prior art feature, which can be achieved by clamping the dust collector bag 6 with high strength, and will not be disclosed in detail here.

[0039] As a technical optimization of the present invention, the blower assembly includes an "L"-shaped rectangular inner tube 17 formed inside the housing 1. The top of the vertical end of the rectangular inner tube 17 penetrates the top wall panel of the housing 1. The top wall panel of the vertical end of the rectangular inner tube 17 is on the same horizontal plane as the top wall panel of the feed hopper 9. The horizontal end of the rectangular inner tube 17 communicates with the partition cavity 23 and is located below the receiving cavity 20. A mesh plate 22 is fixedly connected to the horizontal end port of the rectangular inner tube 17, and a blower 21 is fixedly connected to the center of the horizontal end of the rectangular inner tube 17. The rectangular inner tube 17, through the auxiliary telescopic rod 10 of the rectangular sleeve 4, limits the position of the dust cover 5, allowing the dust cover 5 to effectively cover the top of the feed hopper 9.

[0040] As a technical optimization of the present invention, an inclined guide groove is provided on one side of the housing 1. This guide groove is connected to the center of the vertical end of the rectangular inner tube 17. A filter plate 24 is fixedly connected in the guide groove. A collection box 2 is fixedly connected to the side of the guide groove away from the rectangular inner tube 17. A sealing cover 3 is provided at the bottom of the side of the collection box 2 away from the filter plate 24. The width of the guide groove is greater than the thickness of the filter plate 24. The collection box 2 is connected to the rectangular inner tube 17 through the space above the filter plate 24 in the guide groove. An installation sleeve is fixedly connected to the outer side of the filter plate 24. A vibration rod 33 is fixedly connected to one side of the installation sleeve. A rectangular platform is provided on one side of the mounting plate 13. The end of the vibration rod 33 away from the installation sleeve is fixedly connected to the rectangular platform on the side of the mounting plate 13. The filter plate 24 is similar to the filter element of a car air conditioner, which can be cleaned to maintain the ventilation efficiency of the filter plate 24. The filter plate 24 is a prior art, commonly found in air conditioning filters and vacuum cleaner filters, and will not be disclosed in detail here.

[0041] As a technical optimization of the present invention, an extension plate is fixedly connected to the center of both sides of the top of the dust cover 5. The telescopic end of the telescopic rod 10 is fixedly connected to the bottom of the extension plate. The fixed end of the telescopic rod 10 is fixedly connected to the top wall panel of the housing 1. A one-way valve is provided on one side of the top of the dust cover 5. A rectangular sleeve 4 is connected to the side of the top of the dust cover 5 away from the one-way valve. The rectangular sleeve 4 is "L"-shaped and its vertical end is slidably sleeved on the outside of the rectangular inner tube 17. A right-angled trapezoidal abutment push plate 29 is fixedly connected to the bottom of the vertical end of the rectangular sleeve 4. The abutment push plate 29 is in movable contact with the mounting box 28. The abutment push plate 29 can effectively reinforce the mounting box 28, so that the mounting box 28 will not move from the bottom of the feed hopper 9. The positioning plate 31 can effectively position the mounting box 28.

[0042] As a technical optimization of the present invention, a rectangular groove 34 is provided at the bottom of one end of the feeding hopper 9. A positioning plate 31 is fixedly connected to the center of the bottom of the feeding hopper 9. The positioning plate 31 abuts against the mounting box 28. Multiple inclined rods 35 are fixedly connected to the bottom of the feeding hopper 9 away from the rectangular groove 34. The lowest end of the inclined rods 35 faces the rectangular groove 34. The mounting box 28 is slidably connected in the rectangular groove 34. A reciprocating slider 30 is slidably connected inside the mounting box 28. Multiple unclogging rods 36 are fixedly connected to one side of the reciprocating slider 30. Multiple grooves are provided on the side of the mounting box 28 away from the push plate 29. The multiple unclogging rods 36 are slidably connected in the multiple grooves. The multiple unclogging rods 36 and the multiple inclined rods 35 are intersected but do not abut against each other. A guide slope 38 is provided at the top of the reciprocating slider 30. The lowest end of the guide slope 38 is located at the end of the reciprocating slider 30 away from the push plate 29. The reciprocating slider 30 performs a cyclical lifting and lowering motion. The configuration of the reciprocating slider 30 is existing technology and will not be disclosed in detail here.

[0043] As a technical optimization of the present invention, a discharge port 37 is provided on one side of the housing 1, which communicates with the partition cavity 23. The conveyor belt 15 extends through the discharge port 37 to the outside of the housing 1. One of the rotating shafts of the conveyor belt 15 is rotatably sleeved in one end wall plate of the partition cavity 23, and the other rotating shaft of the conveyor belt 15 is located on the outside of the housing 1. The width of the conveyor belt 15 is the same as the width of the partition cavity 23. Multiple "L"-shaped partitions 7 are provided on the top of the conveyor belt 15. The partitions 7 are fixedly connected to the wall plate of the housing 1. The horizontal end of the partition 7 passes through the discharge port 37, and the wall plate at the horizontal end of the partition 7 is fixedly connected to the top wall plate of the discharge port 37. The vertical end of the partition 7 is located at the end of the conveyor belt 15 in the conveying direction. The partitions 7 can effectively restrict the space for the crops to fall, thereby effectively separating the fully broken, incompletely broken, and metal or stone impurities contained in the crops.

[0044] In use, the dust cover 5 is first raised by the telescopic rod 10. When the dust cover 5 rises, it will also raise the rectangular sleeve 4. When the rectangular sleeve 4 rises, it will slide relative to the rectangular inner tube 17, thereby opening the feed hopper 9. At this time, crops are added to the feed hopper 9. During the process of adding crops, the fan 21 is turned on. After the fan 21 is turned on, it will draw air from the bottom of the dust cover 5 through the rectangular inner tube 17 and the rectangular sleeve 4, thereby removing the dust contained in the crops due to drying, preventing large-scale dust from occurring during the process of adding crops to the feed hopper 9, and reducing the dust generated during the crushing and pulverizing of crops.

[0045] After the crops are added to the feed hopper 9, the dust cover 5 is lowered by the retraction of the telescopic rod 10, effectively sealing the feed hopper 9. Then, the drive motor 8 is turned on and the electromagnet 27 is energized by the battery 12. After the electromagnet 27 is energized, it applies a magnetic force to the crushing block 25 through the magnetic plate 32, causing the magnetic plate 32 to push the crushing block 25 away from the electromagnet 27. This allows the crushing block 25 to effectively crush the crops that have entered the crushing chamber 19, thus achieving effective cell wall breaking. When the compaction block 25 is used to break down the cell walls of crops, if hard impurities such as metal or stones are mixed into the crops due to drying, the compaction block 25 can rebound through the sliding groove 26 when it comes into contact with the metal or stones. This allows the compaction block 25 to float to a certain extent, preventing the compaction block 25 from being damaged due to contact with the metal or stones, which would otherwise result in insufficient compaction and cell wall breaking of the crops.

[0046] When crops fall from the feed hopper 9 into the crushing chamber 19, the crushing roller 16 effectively crushes the crops. After crushing, the crops fall into the receiving chamber 20 through the crushing chamber 19. The receiving chamber 20 guides the crops to disperse effectively. After dispersing, the crops are guided along the inclined groove at the bottom of the receiving chamber 20, making the crushed crops thinner when they fall into the separating chamber 23, thus enabling the crops to disperse effectively. The air blown by the blower 21 blows on the crushed crops, blowing the smaller crushed crops away from the collection box 2. This allows the well-crushed crops to fall in a parabolic motion under the blowing of the blower 21, so that the smaller crushed crop particles fall onto the conveyor belt 15 away from the collection box 2. The partition 7 can effectively separate the crops at this time, preventing the mixing of crops with different crushing degrees.

[0047] Hard objects such as metal or stones present in the crops will fall almost vertically under the influence of gravity, causing them to land on the conveyor belt 15 near the collection box 2. There, they are blocked by the partition 7. Crops that are not fully broken will fall onto the conveyor belt 15 in the middle. The partition 7 effectively separates the impurities such as metal or stones, allowing them to be separated by the action of the conveyor belt 15 and the partition 7. The crops can be collected by placing a box for collecting crops or impurities at the bottom of the vertical end of the partition 7. After sorting and recycling the incompletely cell-wall-breaking crops, the incompletely cell-wall-breaking crops can be poured into the feed hopper 9 during the next cell-wall-breaking process, so that the crops can be effectively and completely broken down. During the blowing process, the air blown into the partition chamber 23 by the blower 21 will leave the partition chamber 23 through the rectangular air outlet pipe 18. The starch and other substances produced after the crop cell-wall breaking can be blown into the rectangular air outlet pipe 18 by the wind, and then effectively collected by the dust collector bag 6. After collection, the dust collector bag 6 can be disassembled and recycled.

[0048] After the dust cover 5 is fitted onto the feed hopper 9, the blower 21 draws air from the dust cover 5 through the rectangular inner tube 17. The airflow enters the dust cover 5 through the one-way valve on the side of the dust cover 5, and then passes through the rectangular sleeve 4 and the rectangular inner tube 17 before being drawn by the blower 21. The air drawn by the blower 21 carries the dust and impurities contained in the crops in the feed hopper 9. The dust and impurities enter the rectangular inner tube 17 with the airflow, and then fall onto the filter plate 24 through the guide of the rectangular inner tube 17. The filter plate 24 blocks the dust and impurities, causing the dust and impurities to change their trajectory under the action of the inclined filter plate 24, so that the dust can fall into the collection box 2 under the action of inertia. The dust adhering to the filter plate 24 can be shaken off by the action of the vibration rod 33, so that the dust can enter the collection box 2. When the drive motor 8 is working, the vibration generated by the rotation of the drive motor 8 will be transmitted to the vibration transmission rod 33 through the mounting plate 13, and then transmitted to the filter plate 24 through the vibration transmission rod 33. The vibration will shake off the dust on the filter plate 24 and make the dust fall into the collection box 2, thereby ensuring the ventilation efficiency of the filter plate 24 and enabling the fan 21 to effectively blow away the crops.

[0049] After the crops fall into the feed hopper 9, they will fall down along the feed hopper 9. When the crops fall onto the inclined bar 35, larger stones or metal impurities in the crops will be guided by the inclined bar 35 and fall onto the top of the guide inclined surface 38 inside the mounting box 28. After the stones or metal impurities fall onto the guide inclined surface 38, they will also carry the crops onto the guide inclined surface 38. Through the setting of the reciprocating slider 30, when the drive motor 8 is working, the reciprocating slider 30 performs a cyclical lifting and lowering motion, thereby causing the guide inclined surface 38 to collect the crops, stones, and... Metal impurities are pushed to the top of the mounting box 28, allowing crops to fall into the compaction chamber 19 through the gap between the unblocking rod 36 and the inclined rod 35. Stones or metal impurities will fall back into the mounting box 28 under the protection of the unblocking rod 36 and the inclined rod 35. After compaction, the extension of the telescopic rod 10 causes the dust cover 5 to rise through the rectangular sleeve 4, causing the abutting push plate 29 to separate from the mounting box 28. At this time, the technician can pull the mounting box 28 out of the feed hopper 9 and then remove the stones or metal impurities.

[0050] The inclined bar 35 effectively limits the amount of crops falling, thus limiting the amount of crops. The unblocking bar 36 moves up and down under the action of the reciprocating slider 30. The unblocking bar 36 slides in the space between adjacent inclined bars 35, thus unblocking the space between the inclined bars 35 and preventing crops from getting stuck at the connection between the feed hopper 9 and the crushing chamber 19.

[0051] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
