Description

Technical Field

[0001] This utility model relates to the field of grain processing technology, and in particular to a dust removal device for grain processing. Background Technology

[0002] Grain processing refers to the industrial process of systematically treating grains through physical, chemical, or biological methods to change their original form, improve their edible quality, extend their shelf life, or extract functional components. Among these processes, dust removal equipment for grain processing is used to capture, filter, and remove dust generated during the handling and processing of grains, such as cleaning, screening, milling, and packaging, in order to ensure a clean production environment, safe equipment operation, and the health of personnel.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Since the filter plates inside the existing dust removal equipment for grain processing are all connected to the equipment by welding, it is impossible to replace the filter plates according to the different grains being processed. The filter plates with fixed pore sizes can only optimize the filtration effect of a single grain. When switching grain types, if the filter plate pore size is too small, it will affect the wind speed and will not be able to collect large dust particles, resulting in a reduction in dust collection effect. If the filter plate pore size is too large, it is easy for small-volume grains to be accidentally sucked into the dust collection equipment. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that the existing dust removal equipment for grain processing has the disadvantage that the filter plate is welded to the equipment and cannot be replaced according to the grain being processed, resulting in poor dust collection effect. Therefore, we propose a dust removal equipment for grain processing.

[0005] To achieve the above objectives, this application adopts the following technical solution: a dust removal device for grain processing, comprising a grain processing device, a cover plate installed at the top of the grain processing device, a ventilation groove formed at the top of the cover plate, a feed inlet provided at the top of the cover plate, a ventilation pipe installed inside the ventilation groove, a dust collection box installed at the other end of the ventilation pipe, a filter plate installed inside the ventilation groove, two fixing blocks fixedly connected to the top of the filter plate, a through groove formed inside the fixing block, a push rod slidably connected inside the through groove, structural grooves formed on both sides of the inner wall of the ventilation groove, a first spring fixedly connected inside the structural groove, a connecting block fixedly connected to the other end of the first spring, and the surface of the connecting block slidably connected to the inside of the through groove.

[0006] Preferably, a limiting ring is fixedly connected to the surface of the connecting block, and the surface of the limiting ring is slidably connected to the interior of the structural groove.

[0007] Preferably, two locking blocks are fixedly connected inside the ventilation groove, and two locking slots are opened on the surface of the filter plate, with the surface of the locking blocks engaging with the inside of the locking slots.

[0008] Preferably, a second spring is slidably connected to the surface of the push rod, one end of the second spring is fixedly connected to one side of the push rod, and the other end of the second spring is fixedly connected to one side of the groove.

[0009] Preferably, a second spring is slidably connected to the surface of the push rod, one end of the second spring is fixedly connected to one side of the push rod, and the other end of the second spring is fixedly connected to one side of the groove.

[0010] Preferably, the bottom of the cover plate is threadedly connected to a receiving plate.

[0011] Preferably, a rubber pad is installed on the top of the receiving plate, and the top of the rubber pad is in contact with the bottom of the filter plate.

[0012] The technical effects and advantages of this utility model are as follows: In this invention, when the filter plate is installed inside the ventilation groove, the filter plate is placed on top of the ventilation groove and pressed down so that the bottom of the filter plate contacts the top of the connecting block. The arc at the bottom of the filter plate presses down on the connecting block, causing the connecting block to automatically move into the interior of the structural groove. When the filter plate is pressed down to the appropriate position, the first spring automatically abuts against the connecting block and enters the interior of the groove, thus limiting the filter plate inside the ventilation groove. When the grain processing equipment screens the grain, dust is generated. The dust collection box generates suction to draw the dust from the ventilation groove through the ventilation pipe into the dust collection box. The filter plate prevents grains from being accidentally sucked into the dust collection box. When it is necessary to separate and replace the filter plate from the inside of the ventilation slot, press the push rod to push the connecting block out of the slot, thereby releasing the locking between the connecting block and the slot. The filter plate can then be separated from the inside of the ventilation slot for maintenance or replacement. This feature allows for flexible replacement of filter screens with different pore sizes or materials to suit the dust characteristics of different grains such as wheat, corn, and soybeans. At the same time, adjusting the pore size according to the size of the grains prevents grains from being sucked into the dust collection box along with gravel. Attached Figure Description

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] Reference Figures 1-4As shown, this utility model provides a technical solution: a dust removal device for grain processing, including a grain processing device 1. A cover plate 2 is installed on the top of the grain processing device 1. A ventilation groove 3 is opened on the top of the cover plate 2. A feed inlet 4 is provided on the top of the cover plate 2. A ventilation pipe 5 is installed inside the ventilation groove 3. A dust collection box 6 is installed at the other end of the ventilation pipe 5. A filter plate 7 is installed inside the ventilation groove 3. Two fixing blocks 8 are fixedly connected to the top of the filter plate 7. A through groove 9 is opened inside the fixing block 8. A push rod 10 is slidably connected inside the through groove 9. Structural grooves 11 are opened on both sides of the inner wall of the ventilation groove 3. A first spring 12 is fixedly connected inside the structural groove 11. A connecting block 13 is fixedly connected to the other end of the first spring 12. The surface of the connecting block 13 is slidably connected to the inside of the through groove 9. When the filter plate 7 is installed inside the ventilation groove 3, the filter plate 7 is placed on the top of the ventilation groove 3 and pressed down so that the bottom of the filter plate 7 is connected to the top of the connecting block 13. The arc of the bottom of the filter plate 7 is pressed down. Block 13 automatically moves into the interior of the structural groove 11. When the filter plate 7 is pressed down to the appropriate position, the first spring 12 automatically abuts against the connecting block 13 and enters the interior of the through groove 9, so that the filter plate 7 is limited inside the ventilation groove 3. When the grain processing equipment 1 screens the grain, dust is generated. The dust collection box 6 generates suction to draw the dust from the ventilation groove 3 into the interior of the dust collection box 6 through the ventilation pipe 5. The filter plate 7 can prevent grain from being accidentally sucked into the interior of the dust collection box 6. When it is necessary to separate and replace the filter plate 7 from the interior of the ventilation groove 3, press the push rod 10 to push the connecting block 13 out of the interior of the through groove 9, so that the locking between the connecting block 13 and the through groove 9 is released, and the filter plate 7 can be separated from the interior of the ventilation groove 3 for maintenance or replacement. Through this setting, different pore sizes or materials of filter screens can be flexibly replaced to adapt to the dust characteristics of different grains such as wheat, corn, and soybeans. At the same time, the appropriate pore size can be adjusted according to the size of the grain to prevent the grain and gravel from being sucked into the interior of the dust collection box 6 together.

[0017] Reference Figure 4 As shown in this embodiment: a limiting ring 14 is fixedly connected to the surface of the connecting block 13. The surface of the limiting ring 14 is slidably connected to the inside of the structural groove 11. By setting the limiting ring 14, the movement position of the connecting block 13 can be restricted, preventing the connecting block 13 from coming out of the inside of the structural groove 11 due to the excessive elasticity of the first spring 12, and ensuring the stability of the filter plate 7 in the ventilation groove 3.

[0018] Reference Figure 3 and Figure 4As shown in this embodiment: two locking blocks 15 are fixedly connected inside the ventilation groove 3, and two locking slots 16 are opened on the surface of the filter plate 7. The surface of the locking block 15 and the inside of the locking slot 16 are engaged with each other. By setting the locking slot 16 and the locking block 15, the filter plate 7 can be stably placed inside the ventilation groove 3 to avoid shaking, and at the same time, it can play a preliminary positioning role during installation.

[0019] Reference Figure 3 As shown in this embodiment: a second spring 17 is slidably connected to the surface of the push rod 10. One end of the second spring 17 is fixedly connected to one side of the push rod 10, and the other end of the second spring 17 is fixedly connected to one side inside the through groove 9. By setting the second spring 17, the elasticity of the second spring 17 abuts against the push rod 10, which can make the push rod 10 automatically reset, and at the same time restrict the movement of the push rod 10.

[0020] Reference Figure 3 As shown in this embodiment: sliding grooves 18 are provided at the top and bottom of the push rod 10, and sliding blocks 19 are fixedly connected to the top and bottom of the through groove 9 side. The surface of the sliding block 19 is slidably connected to the inside of the sliding groove 18. By moving the sliding block 19 inside the sliding groove 18, the movement of the push rod 10 can be guided, so that the push rod 10 will not produce unnecessary displacement when moving inside the through groove 9.

[0021] Reference Figure 5 As shown in this embodiment: the bottom of the cover plate 2 is threadedly connected to the support plate 20. By setting the support plate 20, the filter plate 7 can be installed on the top of the support plate 20, which can make the filter plate 7 more stable inside the ventilation groove 3, and at the same time disperse the local stress when the filter plate 7 is under pressure.

[0022] Reference Figure 5 As shown in this embodiment: a rubber pad 21 is installed on the top of the receiving plate 20. The top of the rubber pad 21 is in contact with the bottom of the filter plate 7. By setting the rubber pad 21, the rubber pad 21 can serve as a flexible buffer layer, effectively isolating the vibration generated during the operation of the grain processing equipment 1 and the dust collection box 6, and preventing the vibration from being directly transmitted to the filter screen.

[0023] Working principle: When the filter plate 7 is installed inside the ventilation groove 3, the filter plate 7 is placed on top of the ventilation groove 3 and pressed down so that the bottom of the filter plate 7 contacts the top of the connecting block 13. The arc at the bottom of the filter plate 7 presses down on the connecting block 13, causing the connecting block 13 to automatically move into the interior of the structural groove 11. When the filter plate 7 is pressed down to the appropriate position, the first spring 12 automatically abuts against the connecting block 13 and enters the interior of the through groove 9, so that the filter plate 7 is limited inside the ventilation groove 3. When the grain processing equipment 1 screens the grain, dust is generated. The dust collection box 6 generates suction to draw the dust out of the ventilation groove. 3. Grains are drawn into the dust collection box 6 through the vent pipe 5. The filter plate 7 prevents grains from being accidentally drawn into the dust collection box 6. When it is necessary to separate and replace the filter plate 7 from the vent 3, press the push rod 10 to push the connecting block 13 out of the through groove 9, thereby releasing the engagement between the connecting block 13 and the through groove 9. The filter plate 7 can then be separated from the vent 3 for maintenance or replacement. This setting allows for flexible replacement of filter screens with different pore sizes or materials to adapt to the dust characteristics of different grains such as wheat, corn, and soybeans. At the same time, the appropriate pore size can be adjusted according to the size of the grain to avoid... Grain-free materials, along with crushed sand and gravel, are sucked into the dust collection box 6. A limiting ring 14 restricts the movement of the connecting block 13, preventing it from detaching from the structural groove 11 due to excessive elasticity of the first spring 12. This ensures the stability of the filter plate 7 within the ventilation groove 3. The slot 16 and locking block 15 stabilize the filter plate 7 within the ventilation groove 3, preventing shaking and providing initial positioning during installation. A second spring 17, with its elasticity, abuts against the push rod 10, allowing it to automatically reset. To limit the movement of push rod 10, the movement of push rod 10 can be guided by the sliding block 19 moving inside the sliding groove 18, so that push rod 10 will not make unnecessary displacement when moving inside the groove 9. By setting the support plate 20 and installing the filter plate 7 on the top of the support plate 20, the filter plate 7 can be more stable inside the ventilation groove 3, and the local stress of the filter plate 7 under pressure can be dispersed. By setting the rubber pad 21, the rubber pad 21 can act as a flexible buffer layer, which can effectively isolate the vibration generated by the operation of grain processing equipment 1 and dust collection box 6, and prevent the vibration from being directly transmitted to the filter screen.

[0024] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
