Description

Technical Field

[0001] The invention relates to the technical field of air shower room dust removal, and in particular to a high-efficiency air shower room dust removal, purification and separation equipment and a separation and purification method. Background Art

[0002] Air showers are mainly used to remove dust or other impurities brought in by people or objects when they enter and leave clean rooms or other controlled environments. Air showers are usually installed at the entrance of clean rooms and are more common in dust-free workshops such as electronic products. That is, workers need to undergo air shower dust removal in the air shower before entering the dust-free workshop. Strong multi-directional airflow will blow away dust, fibers and other impurities attached to the surface to prevent impurities from entering the dust-free workshop and affecting the normal production of electronic products.

[0003] In the prior art, a large number of air shower room dust removal and corresponding devices are also disclosed. For a more accurate comparison, a Chinese patent with publication number CN108325943A discloses a high-efficiency purification air shower room, including a dust-free room, a ventilating port is provided on one side of the dust-free room, a transfer window is provided on the other side of the dust-free room, a door panel is provided on one side of the transfer window, an air shower room is provided on the outside of the door panel and the transfer window, a fan is provided on one side of the air shower room, an air inlet pipe is provided on one side of the fan, and the air inlet pipe runs through one side of the dust-free room, and an air outlet pipe is provided on the other side of the fan.

[0004] When the above-mentioned prior art is in use, a worker enters the air shower room, and fan 1 extracts the clean air in the clean room and sprays it to wash the clean clothes worn by the worker, blowing away the dust particles or fibers on the surface. Fan 2 extracts the dusty air after wind washing to the outside to prevent dust from being suspended in the air and entering the clean room with the workers or goods.

[0005] However, in the process of using the above-mentioned prior art to perform air shower dust removal on the staff entering the clean room, there are still the following shortcomings:

[0006] 1. Since the air contains a large amount of impurities such as dust, hair and fiber, the air shower room is prone to absorb impurities in the air when absorbing air. The above-mentioned prior art cannot filter and purify the air entering the clean room, which easily leads to impurities in the air in the clean room. When the air in the clean room is blown into the air shower room, it is easy to carry impurities, thus affecting the dust removal effect of the air shower.

[0007] 2. Although the air in the air shower room can be extracted by fan 2, the dust and other impurities on the workers are easily blown up and fly during the air shower dust removal process. Therefore, the impurities in the air shower room cannot be quickly removed by exhausting air, resulting in impurities remaining in the air shower room, affecting the air shower dust removal effect on the workers.

[0008] Therefore, based on the above-stated viewpoints, there is still room for improvement in the dust removal methods of air shower rooms in the prior art. Summary of the invention

DETAILED DESCRIPTION

[0046] The following is combined with Figure 1-Figure 10 Embodiments of the present invention are described in detail.

[0047] The embodiment of the present application discloses a high-efficiency air shower dust removal, purification and separation device. It should be noted that the high-efficiency air shower dust removal, purification and separation device of the present application is mainly used in the process of dust removal and purification of the air shower room 1. In terms of technical effect, the air entering the air shower room 1 can be filtered through the purification tank 7 in multiple stages to filter out dust and other impurities in the air, thereby ensuring that the air discharged into the air shower room 1 does not contain dust and other impurities, thereby ensuring the air shower effect. In particular, during the air shower process, the air outlet nozzle 4 can blow air downward and make the dust fly downward, so as to remove the dust in the air shower room 1. It can not only remove the dust on the staff, but also ensure that the air shower room 1 is in a dust-free state.

[0048] Reference Figure 1 As shown, a high-efficiency air shower dust removal, purification and separation equipment comprises an air shower room 1, inlet and outlet are provided on both sides of the width direction of the air shower room 1, doors 2 are installed at the inlet and outlet, an air storage chamber 3 of an inverted U-shaped structure is provided on the outer wall of the air shower room 1, a plurality of air outlet nozzles 4 are installed on the inner wall of the air storage chamber 3, the air outlet nozzles 4 are connected with the air storage chamber 3, and the air outlet nozzles 4 extend to the inside of the air shower room 1 and then tilt downward, a dust reduction unit 5 for discharging air carrying dust therein is installed at the bottom of the air shower room 1, the dust reduction unit 5 comprises an exhaust port opened at the bottom of the air shower room 1, an air pump 6 is installed on the outer wall of the air storage chamber 3, the output end of the air pump 6 is connected with the air storage chamber 3, and the input end of the air pump 6 is installed with a purification tank 7 for purifying and filtering the air entering the air shower room 1.

[0049] During the specific implementation process, the staff first enters the air shower room 1, then closes the door 2, and then starts the air pump 6. The air pump 6 transports air to the air storage chamber 3, and then sprays the air in the air storage chamber 3 at high speed through the air outlet nozzle 4, so as to air shower the staff. During this period, the staff raises their hands and slowly turns 360 degrees to achieve comprehensive air showering and dust removal; during the air shower process, the air outlet nozzle 4 blows air downward and makes the dust fly downward, so as to cooperate with the dust reduction unit 5 to remove the dust in the air shower room 1, which can not only remove the dust on the staff, but also ensure that the air shower room 1 is in a dust-free state, thereby preventing the flying dust in the air shower room 1 from falling on the staff and being carried into the dust-free workshop; in addition, the input end of the air pump 6 can be filtered and purified through the purification tank 7 to prevent dust from being contained in the air inhaled by the air pump 6.

[0050] Reference Figure 2 As shown, in order to prevent the dust blown down by the staff in the air shower room 1 from flying and easily entering the dust-free workshop during the air showering, the dust in the air shower room 1 can be removed in this embodiment. Based on this, a corresponding dust reduction unit 5 is provided in this embodiment. Specifically, the dust reduction unit 5 also includes a support frame 51 installed on the bottom wall of the air shower room 1 in a detachable manner. The support frame 51 is located above the exhaust port. A plurality of equally spaced top support bars 52 are installed on the upper end of the support frame 51. The support frame 51 and the plurality of top support bars 52 form a bracket for the staff to stand. A through hole is formed between two adjacent top support bars 52 to facilitate the downward discharge of air in the air shower room 1. A plurality of connecting rods 53 corresponding to the positions of the top support bars 52 are installed on the inner wall of the exhaust port. Support ribs 54 are installed between the top support bars 52 and the connecting rods 53 at corresponding positions. The connecting rods 53 and the support ribs 54 can provide an upward supporting force to the top support bars 52 to ensure the strength and stability of the top support bars 52 during use. It should be noted that the support ribs 54 are installed at the bottom of the top support bars 52, and the bottom of the support ribs 54 abut against the connecting plate.

[0051] Furthermore, in this embodiment, lifting blocks 55 are installed at the four corners of the bottom of the air shower room 1, and a mounting frame 56 is provided between the plurality of lifting blocks 55. A filter element 57 resting against the lower end of the exhaust port is detachably mounted on the mounting frame 56.

[0052] During the specific implementation process, when the air outlet nozzle 4 sprays air downward, the air carries the dust blown off the staff and is blown downward into the through hole, and then passes through the filter element 57 and is blown out to the outside of the air shower room 1. During this period, the dust in the air can be filtered out by the filter element 57, so that the dust is adsorbed on the filter element 57, thereby ensuring that the interior of the air shower room 1 is in a dust-free state after the air shower is completed, thereby preventing the staff from having dust on their bodies after the air shower is completed, which will cause adverse effects on the working environment of the dust-free workshop.

[0053] Reference Figure 1 and Figure 3 As shown, in order to further reduce the dust in the air shower room 1, the present application can perform corresponding purification and filtration when the air is sucked in at the input end of the air pump 6. Specifically, a fixing plate 11 is installed on one side wall of the air shower room 1 close to the air pump 6, and a purification tank 7 is arranged at the upper end of the fixing plate 11. The purification tank 7 consists of a top cover 71 and a positioning cylinder 72. The top cover 71 and the positioning cylinder 72 are rotatably connected by hinges. Mesh frames 73 are installed on the inner walls of the top cover 71 and the positioning cylinder 72. The two mesh frames 73 abut against each other, and a filter pad is arranged between the two mesh frames 73; the upper end of the top cover 71 is connected to the input end of the air pump 6, an air inlet 74 is opened at any point on the side wall of the positioning cylinder 72, and a dust removal mechanism 75 for intercepting and filtering the air entering the positioning cylinder 72 is installed inside the positioning cylinder 72.

[0054] During the specific implementation process, when the input end of the air pump 6 inhales air through the purification tank 7, the air enters the purification tank 7 from the air inlet 74 and then enters the input end of the air pump 6. During this period, the air entering the purification tank 7 is preliminarily filtered by the dust removal mechanism 75. Secondly, the air inside the purification tank 7 is sucked out upward. At this time, the air can be filtered for a second time through the filter pad to filter out the dust in the air in the purification tank 7, thereby ensuring that the air entering the air shower room 1 is also in a dust-free state, thereby maintaining the dust-free state in the air shower room 1 and the air shower dust removal effect on the staff.

[0055] Reference Figure 4 and Figure 5 As shown, in order to ensure the dust-free state in the air shower room 1, it is necessary to prevent the air entering the air shower room 1 from containing dust. Based on this, in this embodiment, a dust removal mechanism 75 is provided that can filter the air sucked in by the input end of the air pump 6. Specifically, the dust removal mechanism 75 includes an annular groove provided on the inner side wall of the positioning cylinder 72, the annular groove is connected to the air inlet 74, and two annular filter screens 751 are rotatably installed inside the annular groove. Annular rotating frames 752 are installed on the upper and lower sides of the two annular filter screens 751, and the annular rotating frames 752 rotate against the inner wall of the annular groove.

[0056] Furthermore, in this embodiment, an annular gear ring 753 is installed on the inner walls of the two annular rotating frames 752, and two positioning plates 754 distributed up and down are provided on the inner wall of the positioning cylinder 72. A transmission shaft 755 is rotatably passed through the two positioning plates 754, and two gears 756 meshing with the annular gear ring 753 are fixedly sleeved on the outer wall of the transmission shaft 755. A connecting groove for accommodating the gear 756 is provided on the inner wall of the positioning cylinder 72, and a accommodating groove is provided on the inner bottom wall of the positioning cylinder 72. A driving motor 757 connected to the bottom of the transmission shaft 755 is provided inside the accommodating groove.

[0057] In the specific implementation process, when the air pump 6 inhales air, the drive motor 757 is started, and the drive motor 757 drives the transmission shaft 755 and the gear 756 to rotate. The mutual cooperation between the gear 756 and the annular gear ring 753 can drive the annular rotating frame 752 and the annular filter screen 751 to rotate as a whole, so that the annular filter screen 751 can intercept and filter the air entering the purification tank 7 through the air inlet 74, so as to filter out dust and other impurities in the air, and the two annular filter screens 751 can enhance the filtering effect, so that the air can be filtered in multiple stages in cooperation with the filter pad; in addition, the rotating annular filter screen 751 can circulate and filter the air inlet 74, which can not only increase the contact area between the annular filter screen 751 and the air inlet 74 and the contact area with the air entering the purification tank 7, so as to ensure the use effect and filtering performance of the annular filter screen 751, but also avoid the situation where the annular filter screen 751 is prone to blockage during static filtering, thereby further enhancing the filtering effect.

[0058] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in order to enhance the filtering effect of the annular filter 751 on the air inlet 74, the present application can also remove the dust attached to the annular filter 751. Based on this, in the present embodiment, an annular dust collecting hole 758 which is interconnected with the annular groove is provided at the lower end of the positioning cylinder 72, and an inclined guide port is provided on the bottom wall of the annular groove for guiding the dust at the bottom into the annular dust collecting hole 758. A plurality of annularly distributed dust scraping strips 759 are installed on the inner wall of the annular groove and on the opposite sides of the two annular filters 751, and the dust scraping strips 759 are gradually inclined from top to bottom toward one side of the rotation direction of the annular filter 751.

[0059] Furthermore, in this embodiment, a plurality of discharge ports 760 are evenly provided on the annular rotating frame 752 located at the lower side of the annular filter 751, and a plurality of stabilizing plates 761 slidably docked on the inner wall of the annular groove are evenly installed on the outer wall of the annular rotating frame 752. A discharge port for facilitating the falling of dust is formed between two adjacent stabilizing plates 761, and a brush 762 is provided at the lower end of the stabilizing plate 761 for sliding contact with the inner bottom wall of the annular frame.

[0060] During the specific implementation process, when the annular filter screen 751 filters and purifies the air entering the purification tank 7 through the air inlet 74 during the rotation process, part of the intercepted dust adheres to the surface of the annular filter screen 751, and part of it falls downward and passes through the discharge port 760 or the discharge port into the annular dust collection hole 758 and is discharged to the outside of the purification tank 7; during this period, the scraper bar 759 and the annular filter screen 751 are relatively rotated, so the dust attached to the surface of the annular filter screen 751 can be scraped off by the scraper bar 759, and the dust scraped off by the scraper bar 759 falls and is discharged to the outside of the purification tank 7, thereby ensuring that no dust will remain on the surface of the annular filter screen 751, avoiding the dust remaining on the surface of the annular filter screen 751 from penetrating into the interior of the purification tank 7 through the air inlet 74 and affecting the air shower effect, and preventing the dust from causing the annular filter screen 751 to be blocked, thereby ensuring that the filtering performance of the annular filter screen 751 on the air entering the purification tank 7 is not affected.

[0061] While the annular filter 751 and the annular rotating frame 752 are rotating, the annular rotating frame 752 located at the lower side of the annular filter 751 can sweep away the dust remaining on the bottom wall of the annular groove through the brush 762, so that the dust enters the annular dust collecting hole 758 and is discharged to the outside, thereby ensuring that the annular groove remains dust-free, and further ensuring the dust-free state of the air entering the purification tank 7.

[0062] It should be noted that by installing a connecting pipe (not shown in the figure) between the exhaust port at the bottom of the air shower room 1 and the air inlet 74 on the outer wall of the purification tank 7, the purified air discharged from the air shower room 1 can directly enter the purification tank 7 for recycling, thereby using air that is close to dust-free to perform air shower dust removal on the staff, which can further improve the air shower effect.

[0063] Reference Figure 8 and Fig. 9 As shown, in order to further ensure that the air blown into the air shower room 1 does not contain dust, it is necessary to further filter and purify the air entering the purification tank 7. In this embodiment, the dust removal mechanism 75 also includes an air guide pipe 81 installed on the inner wall of the air inlet 74. One end of the air guide pipe 81 is in sliding contact with the inner wall of the annular filter screen 751, and the other end extends to the inside of the positioning cylinder 72. A linkage shaft 83 is rotatably provided on the inner bottom wall of the positioning cylinder 72 through two support plates 82. A circular filter cover 84 is fixedly sleeved on the outer wall of the linkage shaft 83 through an annular sleeve. One end of the air guide pipe 81 away from the air inlet 74 is in sliding contact with the circular filter cover 84; a positioning shaft 85 located below the linkage shaft 83 is installed on the inner bottom wall of the positioning cylinder 72, and mutually meshing bevel gears 86 are sleeved between the linkage shaft 83 and the positioning shaft 85. The positioning shaft 85 is connected to the transmission shaft 755 through a belt drive.

[0064] During the specific implementation process, when the driving motor 757 drives the gear 756 to rotate through the transmission shaft 755 to drive the annular filter screen 751 to rotate through the annular ring gear 753, the air pump 6 sucks air into the purification tank 7, and the air passes through the air inlet 74 and the air duct 81 into the interior of the purification tank 7. The air discharged from the air duct 81 can be further filtered through the circular filter cover 84 to ensure that the air entering the purification tank 7 is in a dust-free state, so that the dust and other impurities entering the air inside the purification tank 7 can be completely removed through multi-stage filtration.

[0065] At the same time, the transmission shaft 755 drives the positioning shaft 85 to rotate synchronously, and the positioning shaft 85 drives the linkage shaft 83 and the circular filter cover 84 to rotate synchronously through the bevel gear 86, so that different positions of the circular filter cover 84 can filter the air discharged from the air duct 81, so as to increase the use area of ​​the circular filter cover 84 and ensure the filtering effect.

[0066] Reference Fig. 9 and Fig.10 As shown, in order to prevent the residual dust on the circular filter cover 84 from flying in the purification tank 7 and causing the air shower room 1 to be unable to be used normally, it is necessary to clean the circular filter cover 84 in time. Based on this, in the present embodiment, a dust removal hole connected to the outside is opened on the inner bottom wall of the positioning cylinder 72, and the upper half of the circular filter cover 84 is located inside the positioning cylinder 72, and the lower half of the circular filter cover 84 extends to the outside after passing through the dust removal hole. A sealing cover 87 is installed at the upper end of the dust removal hole, and the sealing cover 87 is slidably arranged on the outer wall of the circular filter cover 84; mounting plates 88 are installed on both inner walls of the dust removal hole relative to the circular filter cover 84, and a plurality of equidistantly distributed dust removal brushes 89 are arranged on the side of the mounting plate 88 close to the circular filter cover 84.

[0067] During the specific implementation process, when the circular filter cover 84 rotates to filter the air discharged from the air duct 81, since the large particles of dust and impurities in the air have been filtered out under the action of the annular filter mesh 751, the air entering the purification tank 7 contains only small particles of dust, which are easy to adhere to the circular filter cover 84 and are not easy to fall off, so that the circular filter cover 84 can carry the dust and rotate to the dust removal hole; during this period, the circular filter cover 84 and the dust removal brush 89 rotate relative to each other, so the dust removal brush 89 can perform dust removal on both sides of the circular filter cover 84, so as to brush off the dust attached to the circular filter cover 84, thereby ensuring that the circular filter cover 84 is in a dust-free state when it rotates to the inside of the purification tank 7, thereby ensuring the filtering effect of the circular filter cover 84 on the air discharged into the purification tank 7.

[0068] It should be noted that both side walls of the circular filter cover 84 are provided with a plurality of dust collecting holes for collecting dust, and when the circular filter cover 84 carries the dust and rotates into the dust removal hole, the sealing cover 87 is mainly used to isolate the air circulation between the dust removal hole and the purification tank 7, but the sealing cover 87 cannot remove the dust in the dust collecting hole, thereby facilitating the dust to be carried to the outside of the purification tank 7 and removed in time; in addition, the dust removal brushes 89 on the two mounting plates 88 are staggeredly distributed, and when the dust removal brushes 89 brush off the dust on the surface of the circular filter cover 84, the bristles of the dust removal brushes 89 can pass through the circular filter cover 84 and push out the dust on the other side of the surface, and then the dust on the surface of the circular filter cover 84 can be completely removed through the cooperation of the dust removal brushes 89 on both sides.

[0069] In addition, the present invention also provides a high-efficiency air shower dust removal, separation and purification method, comprising the following steps:

[0070] S1: Air shower dust removal: First, the staff enters the air shower room 1, then closes the door 2, and then starts the air pump 6, which transports air to the air storage chamber 3. Then, the air in the air storage chamber 3 is ejected at high speed through the air outlet nozzle 4 to perform air shower on the staff. During this period, the staff raises their hands and slowly turns 360 degrees to achieve comprehensive air shower dust removal.

[0071] S2: Dust removal: During the air shower process, the air outlet nozzle 4 blows air downward and causes the dust to fly downward. The air carries the dust blown off the staff and blows downward into the through hole, and then passes through the filter element 57 and is blown out to the outside of the air shower room 1. During this period, the dust in the air can be filtered out by the filter element 57, so that the dust is adsorbed on the filter element 57, thereby ensuring that the interior of the air shower room 1 is in a dust-free state after the air shower is completed, thereby preventing the staff from having dust on their bodies after the air shower is completed and causing adverse effects on the working environment of the dust-free workshop.

[0072] S3: Air purification: When the input end of the air pump 6 inhales air through the purification tank 7, the air enters the purification tank 7 from the air inlet 74 and then enters the input end of the air pump 6. During this period, the drive motor 757 is started, and the drive motor 757 drives the transmission shaft 755 and the gear 756 to rotate. The gear 756 and the annular gear ring 753 cooperate with each other to drive the annular rotating frame 752 and the annular filter screen 751 to rotate as a whole, so that the annular filter screen 751 can intercept and filter the air entering the purification tank 7 through the air inlet 74, so as to filter out dust and other impurities in the air; in addition, the rotating annular filter screen 751 can circulate and filter the air inlet 74, which can not only increase the contact area between the annular filter screen 751 and the air inlet 74 and the contact area with the air entering the purification tank 7, so as to ensure the use effect and filtering performance of the annular filter screen 751, but also avoid the situation where the annular filter screen 751 is prone to blockage during static filtering, thereby further enhancing the filtering effect.

[0073] During the rotation of the annular filter 751, part of the intercepted dust adheres to the surface of the annular filter 751, and part of it falls downward and enters the annular dust collection hole 758 after passing through the discharge port 760 or the discharge port and is discharged to the outside of the purification tank 7; during this period, the scraping strip 759 and the annular filter 751 rotate relatively to each other and scrape off the dust attached to the surface of the annular filter 751 and discharge it to the outside of the purification tank 7, so as to prevent the dust remaining on the surface of the annular filter 751 from penetrating into the interior of the purification tank 7 through the air inlet 74 and affecting the air shower effect.

[0074] When the air pump 6 sucks air into the purification tank 7, the air passes through the air inlet 74 and the air duct 81 into the interior of the purification tank 7. The air discharged from the air duct 81 can be further filtered through the circular filter cover 84 to ensure that the air entering the purification tank 7 is in a dust-free state, so that the dust and other impurities entering the air inside the purification tank 7 can be completely removed through multi-stage filtration.

[0075] At the same time, the transmission shaft 755 drives the positioning shaft 85 to rotate synchronously, and the positioning shaft 85 drives the linkage shaft 83 and the circular filter cover 84 to rotate synchronously through the bevel gear 86, so that different positions of the circular filter cover 84 can filter the air discharged from the air duct 81, so as to increase the use area of ​​the circular filter cover 84 and ensure the filtering effect; during this period, the circular filter cover 84 and the dust removal brush 89 rotate relative to each other, so the dust removal brush 89 can perform dust removal on both sides of the circular filter cover 84, so as to brush off the dust attached to the circular filter cover 84, thereby ensuring the filtering effect of the circular filter cover 84 on the air discharged into the purification tank 7.

[0076] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.

[0077] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
