Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum packaging, and in particular relates to a multi-stage filtering and anti-clogging device for packaging small-grain seeds. Background Art

[0002] Seed packaging refers to placing seeds in a container or packaging for transportation, storage and sale. Most existing seed packaging is sealed, leaving some air in the packaging bag during packaging, which is prone to breeding microorganisms.

[0003] Therefore, seed vacuum packaging has appeared on the market. During the seed packaging process, the air in the packaging bag is extracted to maintain the bag in a highly reduced pressure state. The scarce air is equivalent to the low oxygen effect, which makes it impossible for microorganisms to survive. However, in the actual packaging process, small particles of seeds are often sucked into the air extraction holes, causing blockage, affecting the packaging work and reducing work efficiency.

[0012] 1. The larger seeds are filtered through the primary filter holes by setting an inner filter cylinder, and the smaller seeds are filtered through the secondary filter holes by setting an outer filter cylinder outside the inner filter cylinder.

During the suction process of the vacuum packaging machine, the seed packaging bag mouth is put on the suction nozzle plug 30 and the suction nozzle 10, and air is inhaled through the suction nozzle 10 and the suction port 31 on the suction nozzle plug 30. The multi-stage filtering structure comprises an inner filter cartridge 40 for the first filtration and an outer filter cartridge 50 for the second filtration. The inner filter cartridge 40 is arranged on one side of the suction nozzle plug 30, located between the inner side of the suction nozzle 10 and the suction nozzle 10, and can be detachably installed. The inner filter cartridge 40 and the air inlet 31 are connected to each other. During the suction process of the vacuum packaging machine, the seed bag is filtered through the inner filter cartridge 40 The gas of the seeds carried in the bag is filtered once, and the outer filter cartridge 50 is arranged on the outside of the inner filter cartridge 40. The air that has been filtered once is then filtered twice through the outer filter cartridge 50, and the air that has been filtered twice is then input into the vacuum machine through the suction nozzle 10, so as to prevent the vacuum machine from being blocked by seeds. The outer filter cartridge 50 and the suction nozzle plug 30 are sealed and detachably connected to ensure that the suction nozzle 10 inhales air through the suction port 31, the inner filter cartridge 40 and the outer filter cartridge 50 in sequence, and a gap is left between the inner filter cartridge 40 and the outer filter cartridge 50. By not fitting between the inner filter cartridge 40 and the outer filter cartridge 50, the outer filter cartridge 50 is effectively prevented from clogging the through holes on the inner filter cartridge 40, and the inner filter cartridge 40 is prevented from clogging the through holes on the outer filter cartridge 50, so as to ensure that the inner filter cartridge 40 performs a high-efficiency filtration of the air once and the outer filter cartridge 50 performs a high-efficiency filtration of the air twice.

[0025] In this embodiment, buckles 20 are fixedly provided on both sides of the port of the suction nozzle 10, and the buckles 20 include a support block 21 fixedly connected to the suction nozzle 10, and a pressure rod 22 is fixedly provided on the side of the support block 21 away from the suction nozzle 10, and the middle position of the pressure rod 22 is fixedly connected to the support block 21, and a claw 23 is fixedly provided at one end of the pressure rod 22 close to the suction nozzle plug 30.

[0026] In this embodiment, the side wall of the inner filter cartridge 40 is penetrated with a plurality of evenly distributed primary filter holes 41 for primary filtration, and the side wall of the outer filter cartridge 50 is penetrated with a plurality of evenly distributed secondary filter holes 51 for secondary filtration, and the aperture of the secondary filter holes 51 is smaller than the aperture of the primary filter holes 41. When the seed particles in the seed packaging bag pass through the primary filter holes 41 on the inner filter cartridge 40 with the flow of air, the larger seeds are filtered out through the primary filter holes 41, and the smaller seed particles are filtered out when passing through the secondary filter holes 51 on the outer filter cartridge 50. When the gas filtered twice is collected into the vacuum packaging machine, the inner side of the vacuum packaging machine can be prevented from being blocked.

[0027] It is worth noting that by setting the primary filter hole 41 on the wall of the inner filter cylinder 40 and the secondary filter hole 51 on the wall of the outer filter cylinder 50, the filter holes are set on the wall to increase the filtering area and improve the filtering effect.

[0028] In this embodiment, fixing rods 36 are fixed on both sides of the suction nozzle plug 30, and the fixing rods 36 are located on both sides of the claws 37. The fixing rods 36 are fixed with claws 37 away from the port of the suction nozzle plug 30. The claws 37 are clamped on the end of the outer filter cartridge 50, and the inner wall of the end of the outer filter cartridge 50 is squeezed on the outer wall of the end of the inner filter cartridge 40. The claws 37 hook the end of the outer filter cartridge 50, so that the outer filter cartridge 50 and the inner filter cartridge 40 can be stably fixed to the suction nozzle plug 30, preventing the outer filter cartridge 50 and the inner filter cartridge 40 from falling off the inner side of the suction nozzle 10 when the outer filter cartridge 50 and the inner filter cartridge 40 are inserted into the suction nozzle 10, thereby ensuring stable filtering operation of the device.

[0029] In this embodiment, a sealing gasket 38 is provided between the nozzle plug 30 and the nozzle 10 for sealing. The sealing gasket 38 effectively prevents air leakage between the nozzle plug 30 and the nozzle 10, ensuring that the vacuum pump sucks air out of the seed packaging bag through the suction port 31 and the nozzle 10 in turn, so that the air containing the seeds is filtered through the outer filter cartridge 50 and the inner filter cartridge 40.

[0030] In this embodiment, an inner connection slot 34 is fixedly provided inside the suction nozzle plug 30 near one end of the suction nozzle 10, and the inner connection slot 34 and the air intake port 31 are interconnected. The inner filter cartridge 40 is sealably and detachably plugged into the inner connection slot 34 to ensure a sealed connection between the suction nozzle plug 30 and the inner filter cartridge 40. An outer connection slot 35 is fixedly provided outside the inner connection slot 34, and the outer filter cartridge 50 is sealably and detachably plugged into the outer connection slot 35 to ensure a sealed connection between the suction nozzle plug 30 and the outer filter cartridge 50. When the vacuum packaging machine is inhaling air, the air in the seed packaging bag is drawn into the vacuum machine through the air intake port 31, the inner filter cartridge 40 and the outer filter cartridge 50 in sequence.

[0031] Specific use method of the utility model: During the use of the multi-stage filtering and anti-clogging device for small-particle seed packaging of the utility model, firstly, the bag mouth of the packaging bag containing seeds is put on the suction nozzle 10 and the suction nozzle plug 30, and the air in the seed packaging bag is extracted by the vacuum packaging machine. The air in the seed vacuum packaging bag is filtered out by the vacuum packaging machine through the suction port 31, the inner filter cylinder 40, the outer filter cylinder 50 and the suction nozzle 10 in turn. When the seed particles in the seed packaging bag pass through the first-level filter hole 41 on the inner filter cylinder 40 with the flow of air, the larger seeds are filtered out through the first-level filter hole 41, and the smaller seed particles are filtered out when passing through the second-level filter hole 51 on the outer filter cylinder 50. When the gas filtered twice is collected into the vacuum packaging machine, the inner side of the vacuum packaging machine can be prevented from being blocked.

[0032] When disassembling the multi-stage filtering anti-clogging device for small-particle seed packaging, first press the end of the pressure rod 22 away from the claw 23 with two fingers, so that the end of the claw 23 on the pressure rod 22 is tilted toward the end away from the suction nozzle plug 30, so that the claw 23 extends from the inner side of the suction hole 32, and the other hand can pinch the suction nozzle plug 30 to pull the suction nozzle plug 30, the inner filter cartridge 40 and the outer filter cartridge 50 out of the suction nozzle 10. After the suction nozzle plug 30, the inner filter cartridge 40 and the outer filter cartridge 50 are pulled out of the suction nozzle 10, hold the outer filter cartridge 50 with one hand. The outer filter cartridge 50 is held in one hand, and the suction nozzle plug 30 is held in the other hand. A pulling force is applied to the outer filter cartridge 50 and the suction nozzle plug 30 in the relative directions. The outer filter cartridge 50 can be shaken left and right to be released from the engagement state between the outer filter cartridge 50 and the second clamping claw 37, so that the outer filter cartridge 50 can be pulled out from the outer connection slot 35. After the outer filter cartridge 50 is pulled out from the outer connection slot 35, the inner filter cartridge 40 can be pulled out from the air inlet 31. The inner filter cartridge 40 and the outer filter cartridge 50 are turned upside down, and the seeds in the inner filter cartridge 40 and the outer filter cartridge 50 can be poured out.

It is worth mentioning that the inner side of the second claw 37 away from the end of the fixing rod 36 is chamfered. When the outer filter cartridge 50 is inserted into the outer connection slot 35, the outer filter cartridge 50 will pass through the two claws 37 to push the two claws 37 apart through the chamfer, so that the fixing rod 36 is squeezed and deformed, and the outer filter cartridge 50 can be made to pass through the two claws 37 to push the two claws 37 apart through the chamfer, so that the fixing rod 36 is squeezed and deformed, so that ... and the outer filter cartridge 50 can be made to pass through the two claws 37 to push the two claws 37 apart through the chamfer, and the fixing rod 36 is squeezed and deform The filter cartridge 50 is inserted into the external connection slot 35. After the external filter cartridge 50 is fully inserted into the external connection slot 35, the second clamping claw 37 disengages and squeezes the external filter cartridge 50, and the fixing rod 36 recovers its deformation. The second clamping claw 37 hooks the end of the external filter cartridge 50, so that the external filter cartridge 50 and the internal filter cartridge 40 are stably fixed to the suction nozzle plug 30, preventing the external filter cartridge 50 and the internal filter cartridge 40 from falling off the inner side of the suction nozzle 10 when the external filter cartridge 50 and the internal filter cartridge 40 are inserted into the suction nozzle 10. After the internal filter cartridge 40 and the external filter cartridge 50 are fixed to the suction nozzle plug 30, the internal filter cartridge 40, the external filter cartridge 50 and the suction nozzle plug 30 can be inserted into the suction nozzle 10, so that the suction nozzle plug 30 and the suction nozzle 10 are plugged in and matched, and the sealing gasket 38 and the suction nozzle 10 are sealed and fixed.
