Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment, in particular to a storage and conveying equipment for grain processing. Background Art

[0002] Grain processing is the process of processing grains harvested from the field through processing equipment. When processing rice, the rice husk on the surface of the rice needs to be processed to retain the plump rice grains, and then the rice grains are stored and wait for subsequent filling and use;

[0003] The invention of the existing publication number CN113120638 A discloses a grain processing equipment including a feeding device, a grain separation device and a connecting device. The scheme points out that when the grain separation device fails and needs to be repaired, the grain separation device can be better separated from the feeding hopper, thereby bringing positive significance to the rice grain and bran powder separation device. When rice is continuously produced and processed, the rice grains need to be transported and stored after being separated from the bran powder. The transportation methods are mainly conveyor belts, screw conveyors and negative pressure lifting and conveying equipment. Since the rice grains are relatively easy to break and shatter after shelling, the screw conveyor is easy to cause damage to the rice grains during transportation. When the conveyor belt method is used to transport the rice grains, it is impossible to perform a large-angle lifting operation. When the negative pressure lifting and conveying equipment is used to store and use the rice grains, since the rice grains still contain a large amount of rice powder after grinding, the filtering mechanism in the existing equipment is relatively simple during negative pressure transportation, which is easy to cause pollution and damage to the negative pressure suction mechanism, and it is impossible to effectively deal with a large amount of rice dust. During the subsequent transfer and transportation, it still brings negative effects to each link. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Please refer to the attached Figure 1-13 , this application provides the following technical solutions.

[0037] Embodiment 1: A storage and conveying equipment for grain processing, comprising a conveyor housing 1, a top cover 2 is provided at the upper end of the conveyor housing 1, a conveying joint 3 is connected to one side of the conveyor housing 1, and negative pressure joints 4 and back-blowing air bags 5 are respectively connected to the two sides of the top cover 2. When in use, the negative pressure joint 4 is connected to the negative pressure suction equipment, and negative pressure is generated in the top cover 2 through the negative pressure joint 4. Similarly, the air in the conveyor housing 1 will also be sucked and lifted. At this time, after the air in the conveyor housing 1 is negatively pressurized, the rice grains after shelling and separation will be lifted through the conveying joint 3 and the connected transport pipe. When the rice grains reach the conveyor housing 1, they will naturally fall to the bottom of the conveyor housing 1 under the action of their own gravity and wait for discharge, or they will be continuously discharged through the self-closing discharger to realize the safe and anti-fragmentation lifting and transportation of the rice grains.

[0038] A filtering component is provided to filter the gas entering the top cover 2 from the conveyor housing 1 to prevent dust in the rice from being sucked into the negative pressure equipment and affecting the service life. A building partition 6 is horizontally provided on one side of the conveyor housing 1 close to the top cover 2. The filtering component is provided on the building partition 6. The filtering component includes a plurality of filter support cylinders 8 and a plurality of filter bags 10. A plurality of fixed circular grooves 7 are provided on the top cover 2. The upper end of the filter support cylinder 8 is plugged into the fixed circular groove 7 and is provided with a fixed disk. The lower end of the filter support cylinder 8 is plugged into the conveyor housing 1, and the lower end of the filter support cylinder 8 placed in the conveyor housing 1 is higher than the horizontal height of the conveying joint 3. A bag installation groove 9 is horizontally provided at the lower end of the filter support cylinder 8. The bag opening of the cloth bag 10 is expanded outward and inserted into the cloth bag installation groove 9. The cloth bag installation groove 9 is provided with a cloth bag pressing ring 11 through a threaded insertion, and one side of the cloth bag pressing ring 11 is pressed and contacted with the side of the filter cloth bag 10 inserted into the cloth bag installation groove 9. When the rice enters the conveyor housing 1 through the conveying joint 3, it will not directly contact the filter support cylinder 8. At this time, the filter cloth bag 10 installed under the filter support cylinder 8 can filter the rice dust raised in the air. At the same time, the installation method of the filter cloth bag 10 through the cloth bag pressing ring 11 is convenient for the replacement and maintenance of the filter cloth bag 10. The side of the filter cloth bag 10 inserted into the cloth bag installation groove 9 can be a metal ring structure, which is pressed tightly to maintain the stability of the connection.

[0039] A plurality of filter bags 10 are respectively arranged in a plurality of filter support cylinders 8 through recovery components, and the recovery components include a central control rod 14 and a blocking collection plate 13. The upper end of the central control rod 14 is vertically movable and arranged in the center of the filter support cylinder 8.

The first clamping support plate 15 is fixedly connected to the central control rod 14, and the second clamping support plate 16 is fixedly connected to the central control rod 14 by threads. The diameter is equal to the inner diameter of the filter bag 10, and the diameters of the first clamping support plate 15 and the second clamping support plate 16 are smaller than the inner diameter of the filter support tube 8. The central control rod 14 is fixedly connected to the bottom of the filter bag 10. When the central control rod 14 is pressed downward, the filter bag 10 will be pulled downward to keep the filter bag 10 taut, thereby achieving a good filtering effect and preventing the wrinkles of the filter bag 10 from affecting the airflow. In addition, when the central control rod 14 drives the first clamping support plate 15 and the second clamping support plate 16 to rise, the bottom of the filter bag 10 will move upward, and at this time the inner and outer sides of the filter bag 10 will be swapped.

[0040] A constraint ring is provided at the lower end of the filter support cylinder 8, and a plurality of guide slide rods 12 are vertically symmetrically provided at the lower end of the constraint ring. A plurality of guide holes are opened on the blocking collection plate 13, and the plurality of guide holes of the blocking collection plate 13 are respectively movably sleeved with the plurality of guide slide rods 12. An arc-shaped collecting groove 26 is opened at the center of the upper end of the blocking collection plate 13, and a connecting bracket 27 is welded at the upper end of the arc-shaped collecting groove 26. The lower end of the central control rod 14 is fixed to the center of the connecting bracket 27 by bolt insertion. A central groove 24 is opened through the center of the central control rod 14, and the lower end of the central groove 24 passes through the connecting bracket 27 and is connected to the arc-shaped collecting groove 26. The arc-shaped collecting groove 26 is used to collect rice dust falling on the surface of the filter bag 10.

[0041] A control component is provided to control the upward and downward movement of the central control rod 14, and to realize the exchange of the inner and outer sides of the filter bag 10. The control component is arranged at the upper end of the filter support cylinder 8. The control component includes a flange mounting plate 20 and a self-rotating screw sleeve 21, and the upper end of the central control rod 14 passes through the self-rotating screw sleeve 21. The fixed plate of the filter support cylinder 8 is located on one side inside the top cover 2 and is provided with an assembly seat 18. The flange mounting plate 20 is horizontally fixed to the upper end of the assembly seat 18 by a plurality of bolts. A plurality of strip-shaped air-permeable grooves 19 are symmetrically penetrated on the guide slide rod 12. A reinforced filter element 34 is vertically provided in the assembly seat 18. The upper and lower ends of the reinforced filter element 34 are respectively abutted against the lower end of the flange mounting plate 20 and the upper end of the fixed plate. The center of the flange mounting plate 20 is rotatably plugged with a self-rotating screw sleeve 21 through a sealed bearing. The upper ends of the self-rotating screw sleeves 21 are horizontally provided with synchronous gears 22. The synchronous gears 22 are connected by a toothed synchronous belt. A control internal thread 23 is vertically penetrated through the center of the self-rotating screw sleeve 21. A control external thread 17 is provided at the upper end of the central control rod 14. The upper end of the central control rod 14 is threadedly inserted into the control internal thread 23 of the self-rotating screw sleeve 21 through the control external thread 17. The upper end of the central control rod 14 placed in the control internal thread 23 is connected and plugged with a powder discharge hose 25. The powder discharge hose 25 penetrates the synchronous gear 22. A centralized suction pipe 33 is provided at the upper center of the top cover 2. Since the blocking collection plate 13 is connected to a number of vertically fixed guide slide rods 12, the blocking collection plate 13 can only move up and down when the synchronous gear 22 rotates. When the central control rod 14 rises to the maximum extent, the upper end of the blocking collection plate 13 abuts against the lower end of the filter support tube 8. At this time, the inner and outer sides of the filter bag 10 will be swapped.

[0042] In this embodiment: when negative pressure is generated in the top cover 2, after the air in the conveyor housing 1 is evacuated, the rice and air are sucked into the conveyor housing 1 from the conveying joint 3. The rice will fall into the lower part of the conveyor housing 1 under the action of its own weight. When the filter bag 10 is in normal use, the filter support cylinder 8 is extended through the central control rod 14 and is in a taut posture. When the gas containing rice dust passes through the filter bag 10, it is fully filtered. After filtration, the gas enters the filter support cylinder 8 and continues to rise. At this time, it is filtered twice through the enhanced filter element 34, and then enters the top cover 2, and is finally sucked away by the negative pressure equipment connected to the negative pressure joint 4. When there is a lot of rice dust adhering to the surface of the filter bag 10, the synchronous gear 22 rotates and moves to control the central control rod 14 to vertically lift the filter bag 1 During the rising process of the central control rod 14, it is placed in the filter support tube 8, and then the sealing collection plate 13 is used to seal the bottom of the filter support tube 8. At this time, the high-pressure gas stored in the back-blowing air bag 5 is filled with high-pressure gas in the top cover 2, and then the high-pressure gas enters the filter support tube 8 through the enhanced filter element 34, and then is back-blown to the surface originally inside the filter bag 10. At this time, the outer side of the filter bag 10 with a large amount of dust accumulated is inside, and the high-pressure gas is back-blown, and the rice dust is blown into the arc-shaped collection groove 26 of the sealing collection plate 13, and then is sucked out through the central groove 24 of the central control rod 14. At this time, the upper end of the powder discharge hose 25 is connected to the centralized suction pipe 33, and the centralized suction pipe 33 can be connected to the environmentally friendly negative pressure suction equipment to perform green environmental protection treatment in the later stage.

[0043] Embodiment 2: On the basis of embodiment 1, a containment assembly is provided to collect more rice dust on the surface of the filter bag 10 and gather it on the blocking collection plate 13. The containment assembly includes a first matching filter cartridge 28 and a second matching filter cartridge 30. The flange mounting plate 20 is movably sleeved with the filter support cylinder 8. The second matching filter cartridge 30 is arranged on the outer peripheral side of the blocking collection plate 13, and the second matching filter cartridge 30 is arranged corresponding to the first matching filter cartridge 28. The first matching filter cartridge 28 is movably prevented from falling off by the constraint ring of the filter support cylinder 8. A downward pressure spring 29 is provided at the upper end of the first matching filter cartridge 28. The downward pressure spring 29 is sleeved with the filter support cylinder 8. The upper end of the downward pressure spring 29 abuts against the lower end of the fixed plate. The diameter of the second matching filter cartridge 30 is larger than the diameter of the first matching filter cartridge 28. The upper end of the second matching filter cartridge 30 The lower end of the first matching filter cartridge 28 is movably sleeved, and a plurality of retention holes 31 are penetrated and opened on the first matching filter cartridge 28 and the second matching filter cartridge 30. The plurality of retention holes 31 are all inclined from the outside to the inside. When the conveyor housing 1 is in the operation of continuously conveying rice, the filter bag 10 can be backblown with gas through the backblowing air bag 5 when it is not retracted into the filter support cylinder 8. At this time, a small amount of rice dust on the surface of the filter bag 10 can be in the first matching filter cartridge 28 and the second matching filter cartridge 30 after backblowing, and then under the action of the downwardly inclined retention holes 31, more dust will fall on the upper end of the blocking collection plate 13. At this time, the powder discharge hose 25 generates negative pressure suction, which can form a negative pressure state in the arc-shaped collection groove 26, accelerate the suction treatment of rice dust, and avoid the continuous influence of rice dust in the later stage of rice conveying.
