Description

Technical Field

[0001] The invention relates to the technical field of down fluffiness detection, and in particular to a dust removal device for pre-processing the fluffiness of down. Background Art

[0002] Down fluff is one of the important indicators of feather quality, and is an important manifestation of elasticity and warmth retention in its inherent quality. Down fluff testing is one of the most important items in feather testing. It is the volume occupied by a certain amount of down feather sample under a specified pressure in a container of a certain diameter.

[0003] The down fluffiness pretreatment process is also called the fluffiness sample preparation process. Its specific content is to put 40g of sample into the pretreatment box and gently break it up with a wooden stick. Use the nozzle of the steam generator to blow steam into the pretreatment box at a distance of 10cm-15cm from the gauze of the pretreatment box, blow for 15s on each side, and blow for 60s on all four sides. After placing the sample for 5min-10min, use a hair dryer to blow dry the sample at a distance of 1cm-2cm from the gauze of the pretreatment box, blow for at least 30s on each side, and blow for more than 2min on all four sides. Check by hand whether the sample is dry. If it is not dry, continue to blow until it is completely dry. This fluffiness pretreatment method is also called the steam reduction method. During the treatment process, a large amount of down, feather, dust, etc. will be generated. These fine fibers and particles seriously damage human health and pollute the test environment.

[0004] The dust removal process of the above method in the prior art has the following defects: 1. Unable to vacuum accurately The suction port of the prior art is located at the top, which cannot accurately suck dust. In addition, the design of the upper suction port often requires raising the machine or lowering the suction port in order to improve the dust collection efficiency. If the machine is raised, it will cause inconvenience to the experimenter to operate, and if the air port is lowered, the whole device will be visually unsightly.

[0005] 2. Easy to clog the pipe After being used for a period of time, the existing technology often causes the precipitation of lint, impurities, etc., which makes the pipeline easily blocked and extremely difficult to clean.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present 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.

[0025] like Figure 1 - Figure 8 As shown, the present invention provides a dust removal device for pre-processing down fluffiness, comprising a sealed box 1, two visible doors hinged on one side of the sealed box 1, a base 2 is arranged inside the sealed box 1, a pre-processing box 3 and an electric heating blower 4 are arranged on the base 2, a rotating device for driving the pre-processing box 3 to rotate is arranged on the base 2, a partition plate 5 and a dust removal hopper 6 are arranged in sequence in the sealed box 1, the partition plate 5 and the dust removal hopper 6 are fixed in sequence in the sealed box 1, and the partition plate 5 and the dust removal hopper 6 divide the sealed box 1 into a purification chamber 11, a filter chamber 13 and a processing chamber 12, and the base 2 is arranged in the processing chamber 12 Inside, a filtering mechanism 7 for adsorbing and filtering fine fibers and particles generated in the processing chamber 12 is provided in the filtering chamber 13, a dust bag 8 is provided in the purification chamber 11, and an air suction port 61 is provided in the dust hopper 6, the air suction port 61 and the output end of the electric hot blower 4 are arranged opposite to each other, and the pre-treatment box 3 is located between the air suction port 61 and the electric hot blower 4, an air inlet pipe 9 is provided on one side of the filtering mechanism 7, the air inlet pipe 9 is fixedly connected to the dust hopper 6 and is communicated with the air suction port 61, and an exhaust pipe 10 is provided on the other side of the filtering mechanism 7, and the other end of the exhaust pipe 10 passes through the partition plate 5 and is connected to the dust bag 8.

[0026] During the pre-treatment process of the down fluffiness experiment, the present invention opens the visual door, places the down sample in the pre-treatment box 3, and then closes the visual door to keep the sealed box 1 in a sealed state. The setting of the visual door can observe the dynamics of the down sample in real time and achieve secondary isolation of down and feather fibers. Then, the electric hot air blower 4 is started. When the electric hot air blower 4 is working, the rotating device is started synchronously, so that the hot air blown by the electric hot air blower 4 can evenly act on the side wall of the pre-treatment box 3 (the pre-treatment box 3 is surrounded by mesh), thereby drying the down sample inside the pre-treatment box 3. Figure 1-Figure 2 As shown, a bracket for fixing the electric hot air blower 4 is provided on the base 2, and the staff can add a steam generator and other equipment for pre-treating the down according to the usage. The down pre-treatment box and related devices are prior art and will not be described in detail here.

[0027] When the electric hot air blower 4 is in the process of drying the down sample, the down fibers, feather fibers, dust, etc. will fly out from the side of the pre-treatment box 3. Therefore, the effect of dust collection on the side of the pre-treatment box 3 is the most ideal. However, if the blowing speed and position are not well controlled, it will often affect the samples inside the fluffy box, such as sucking part of the down sample out of the pre-treatment box 3. Therefore, the prior art before this all adopted the top suction mode, but the top suction mode cannot achieve accurate dust collection and requires greater suction force. Therefore, if the suction force increases, the noise generated will also be greater. In addition, the existing top suction mode is often accompanied by a pipeline, and in the process of drying the down sample, the down fibers, feather fibers, dust, etc. "dust" will easily block the pipeline, making it difficult to clean. In addition, the prior art does not achieve effective collection of "dust", and often uses the characteristics of down fibers and feather fibers that are easy to float to discharge directly to the outside like smoke, which will pollute the environment.

[0028] In order to solve the above problems, the present invention provides a filtering mechanism 7 and a dust removal hopper 6, connects the filter cartridge 71 and the dust removal hopper 6 to the air inlet 9, and at the same time, the air inlet 61 is designed to be parallel to the pre-treatment box 3, so that the air flow is effectively formed to process the "dust" such as down filaments, feather filaments, and dust generated in the process of drying the down sample. The filtering mechanism 7 includes a filter cartridge 71, a down cleaning cartridge 72, a dust suction fan 73, a filter cartridge 74, a driving assembly 75 for driving the filter cartridge 74 to rotate, and a cleaning assembly 76 for scraping and cleaning the down on the periphery of the filter cartridge 74. The down cleaning cartridge 72 A filter chamber 13 is arranged inside the sealed box 1, a filter cartridge 71 is arranged on the top of the down washing cartridge 72, a dust suction fan 73 is installed on the outer top wall of the filter cartridge 71, a ventilation pipe 78 is arranged at the output end of the dust suction fan 73, the ventilation pipe 78 passes through the filter cartridge 71 and the filter screen cartridge 74 in sequence and then extends to the inside of the filter screen cartridge 74, an annular plate 79 is fixedly connected to one side of the inside of the filter cartridge, the filter screen cartridge 74 is rotatably connected in the annular plate 79, a driving assembly 75 is arranged on the filter cartridge 71 and is transmission-connected to the filter screen cartridge 74, a cleaning assembly 76 is arranged inside the filter cartridge 71 and conflicts with the filter screen cartridge 74.

[0029] The driving assembly 75 includes a driving gear 751, a gear ring 752 and a driving motor 753. The gear ring 752 is fixedly mounted on the outer wall of the top of the filter cylinder 74. The driving gear 751 is rotatably set on the annular plate 79, and the driving gear 751 is meshed with the gear ring 752. The driving motor 753 is installed on the outer top wall of the filter cylinder 71, and the output shaft of the driving motor 753 passes through the filter cylinder 71 and is fixedly connected to the rotating shaft of the driving gear 751.

[0030] After the dust suction fan 73 is started, the gas containing the escaped down, feather and light dust in the processing chamber 12 is sucked out from the air suction port 61. After passing through the air suction port 61, the gas enters the filter cartridge 71 through the air inlet pipe 9 and is filtered for the first time to separate the dust and down feathers in the gas. The down feathers are filtered on the outer wall of the filter screen cartridge 74. The gas with dust enters the filter cartridge 71 and is transported to the exhaust pipe 10 through the ventilation pipe 78, so that the separated dust-containing gas is discharged into the dust collecting bag 8 for secondary filtration. Through the setting of the filtering mechanism 7, the impurities such as down, feather and light dust in the processing chamber 12 enter the filter cartridge 71 and are filtered, which not only reduces environmental pollution, but also can further separate and filter the down and dust in the gas. The down feathers collected and filtered can be used after secondary treatment.

[0031] Specifically, when the gas enters the filter cartridge 71, the drive motor 753 on the annular plate 79 is started, and the drive motor 753 drives the drive gear 751 to rotate, thereby driving the gear ring 752 meshing with the drive gear 751 to rotate. When the gear ring 752 rotates, it drives the filter cartridge 74 fixedly connected thereto to rotate, thereby increasing the contact area between the filter cartridge 74 and the gas. When the filter cartridge 74 rotates, it cooperates with the cleaning assembly 76 to scrape off the down and feathers on the outer surface of the filter cartridge 74, thereby avoiding excessive down and feathers adhering to the outer surface of the filter cartridge 74, thereby avoiding affecting the filtering effect of the filter cartridge 74.

[0032] The cleaning assembly 76 includes a positioning plate 761, a fixing rod 762, two fixing plates 763, two scrapers 764 and a blowing structure 765 for assisting the scrapers 764 in scraping down. The positioning plate 761 is rotatably arranged at the bottom of the filter cylinder 74, the two fixing plates 763 are symmetrically fixed on both sides of the positioning plate 761, and the other ends of the two fixing plates 763 are fixedly connected to the inner wall of the filter cylinder 71, the two scrapers 764 are symmetrically arranged on both sides of the outside of the filter cylinder 74, and the upper and lower ends of the two scrapers 764 are respectively fixedly connected to the annular plate 79 and the positioning plate 761, and the two scrapers 764 are in conflict with the outer wall of the filter cylinder 74, the fixing rod 762 is fixedly arranged in the middle of the positioning plate 761, and one end of the fixing rod 762 extends into the filter cylinder 74 after passing through the positioning plate 761, and the other end of the fixing rod 762 extends into the down cleaning cylinder 72, and the blowing structure 765 is located outside the filter cylinder 74 and is fixedly connected to the fixing rod 762.

[0033] The blowing structure 765 includes two contact plates 766 and two pairs of connecting rods 767 which are respectively slidably connected to the two contact plates 766. The two contact plates 766 are respectively arranged inside the filter cylinder 74 and are respectively arranged opposite to the two scrapers 764. The two pairs of connecting rods 767 are respectively fixedly connected to both sides of the fixed rod 762 and are respectively slidably connected to the two contact plates 766. A cavity 768 is provided in the fixed rod 762. An air pump 769 is installed at the bottom of the positioning plate 761. The output end of the air pump 769 passes through the fixed rod 762 and extends into the cavity 768. The air pump A down filter tube is connected to the input end of 769, and a notch 810 communicating with the cavity 768 is provided inside all the connecting rods 767. A bellows 811 is connected between the contact plate 766 and the notch 810. A buffer spring 812 is movably sleeved outside the bellows 811, and both ends of the buffer spring 812 are respectively connected to the contact plate 766 and the connecting rod 767. An air storage cavity 813 communicating with the bellows 811 is provided inside all the contact plates 766, and a plurality of air outlet holes 814 communicating with all the air storage cavities 813 are provided on all the contact plates 766.

[0034] When the filter drum 74 rotates, the two scrapers 764 that abut against the outer wall of the filter drum 74 can scrape off the down feathers adhered to the surface after filtering. In addition, in order to prevent the filter drum 74 from being blocked due to the insertion of down feathers into the mesh of the filter drum 74, which will affect the cleaning effect of the scrapers 764, when the filter drum 74 rotates, the air pump 769 is started, and the air pump 769 filters the external air through the down filter tube and then transmits it to the cavity 768 inside the connecting rod 767. The air passes through the cavity 768 and enters the notch 810 inside the connecting rod 767. The gas entering the notch 810 passes through the bellows 81 1 enters the air storage cavity 813 inside the abutment plate 766, and is blown out to the inner surface of the filter cylinder 74 through the multiple air outlet holes 814, so as to blow out the down feathers attached to the outer surface of the filter cylinder 74 and inserted into the mesh of the filter cylinder 74. With the use of the scraper 764, the down feathers and dust attached to the surface of the filter cylinder 74 can be quickly cleaned, so that the dust removal of the down is realized, and the filter screen is avoided from being blocked by the down dust during the treatment process, so as to ensure the overall dust removal effect and efficiency. The setting of the buffer spring 812 can make the abutment plate 766 always abut against the inner wall of the filter cylinder 74 to prevent the filter cylinder 74 from being concave.

[0035] It is worth noting that in order to avoid conflicts between the use of the dust suction fan 73 and the air pump 769, the start time of the dust suction fan 73 can be set to be intermittent, and the air pump 769 can be started when the dust suction fan 73 is stopped, so that the working times of the two can be staggered.

[0036] A booster assembly 77 for pushing down floating on the water surface of the down cleaning cylinder 72 into the water is arranged inside the down cleaning cylinder 72, and the booster assembly 77 is connected to the bottom of the fixed rod 762. The booster assembly 77 includes a movable rod 771, a sealing member 772 for sealing the bottom of the filter cylinder 71, and a plurality of push plates 773. The top end of the movable rod 771 axially seals and slides on the bottom of the fixed rod 762. A return spring 774 is connected between the movable rod 771 and the fixed rod 762. A valve is arranged on the fixed rod 762. The sealing member 772 is fixedly arranged on the outer wall of the movable rod 771 and is adapted to the bottom outlet of the filter cylinder 71. A plurality of push plates 773 are evenly arranged on the outer wall of the movable rod 771 along the circumferential direction. When the valve is opened, the gas in the cavity 768 pushes the movable rod 771 downward, so that the sealing member 772 opens the bottom of the filter cartridge 71 and pushes the down floating on the water surface into the water.

[0037] In the initial state, in the cavity 768 of the fixed rod 762, the valve located above the output end of the air pump 769 is in the open state, and the valve located below the output end of the air pump 769 is in the closed state. At this time, when the gas enters the cavity 768, it is transported to the contact plate 766, and the blocking member seals the bottom of the filter cartridge 71 to a sealed state. After the filter cartridge 74 has been cleaned for a period of time, the valve located above the output end of the air pump 769 is closed, and the valve located below the output end of the air pump 769 is opened, so that the gas enters the cavity 768 and pushes the movable rod 771 downward, thereby compressing the reset spring 774. In the initial state, the closing member 772 is located at the bottom end of the filter cartridge 72 and closes the bottom of the filter cartridge 71. When the movable rod 771 moves downward, it can drive the closing member 772 and multiple The push plates 773 move downward synchronously, and when the closure member 772 moves downward, the channel at the bottom of the filter cylinder 71 can be opened, so that the down feathers that fall above the closure member 772 after scraping fall into the down cleaning cylinder 72. Clean water is provided inside the down cleaning cylinder 72, and the down feathers float on the water surface. When the movable rod 771 moves downward, the down feathers floating on the water surface can be pushed into the water for cleaning, so as to wash away the dust attached to the surface of the down feathers. Furthermore, the valve located above the output end of the air pump 769 can perform intermittent switching actions, so that the push plate 773 can move back and forth up and down, thereby improving the efficiency of pushing the down into the water, so as to increase the speed at which the down contacts the clean water, improve the effect of cleaning the down, and remove impurities in the down more thoroughly, thereby realizing the collection and utilization of the down.

[0038] It is worth noting that the setting of the filter cylinder 74 can not only filter the down feathers, but also the gas entering the filter cylinder 71, if there are large particles of dust and impurities, will also be filtered out of the filter cylinder 71. When the down feathers scraped by the cleaning component 76 fall into the down cleaning cylinder 72, since the down feathers are light in material, when the down feathers fall onto the water surface in the down cleaning cylinder 72, the down feathers float on the water surface, and the large particles of dust in the gas and the dust on the down feathers increase in weight when they fall into the water, and then settle in the water.

[0039] The down washing cylinder 72 is provided with a drainage pipe 721 and a down discharge pipe 722, and a water injection pipe is also provided on the top of the down washing cylinder 72. Clean water can be added to the down washing cylinder 72 through the water injection pipe. In the initial state, the capacity of the clean water is lower than the position of the down discharge pipe 722. When the down is washed, clean water can be added from the water injection pipe to discharge the down floating on the water surface from the down discharge pipe 722. When the down is discharged, the drainage pipe 721 is opened to discharge the sewage in the down washing cylinder 72.

[0040] All push plates 773 are arranged in an arc-shaped and inclined manner, and the closing member 772 is arranged in a cone shape.

[0041] The arc-shaped inclined setting of the push plate 773 can wrap the down floating on the water surface and push it into the water, thereby increasing the contact area between the down and the water.
