A clean working environment maintenance device

Abstract

This invention provides a clean working environment maintenance device, including a dust collector cylinder, a filter cabinet at one end of the dust collector cylinder, and a top cover on the top of the dust collector cylinder. An air pump is located at the center of the top cover, and the output end of the air pump is connected to the top of the filter cabinet via an air guide pipe. Compared with the prior art, this invention has the following advantages: the dust collector cylinder and filter cabinet are combined, and dust-laden air undergoes coarse filtration in the dust collector cylinder, where dust is intercepted, reducing the dust concentration in the air. Subsequently, the pre-filtered air enters the filter cabinet, where three stages of filters progressively filter and adsorb pollutants and harmful gases of different particle sizes. An ultraviolet sterilization lamp then kills residual microorganisms. This staged filtration method avoids high-concentration dust directly impacting the filter cabinet screens, reducing the risk of filter clogging, while ensuring the cleanliness of the output air, meeting the stringent requirements for a high-cleanliness environment in the production of powder cakes and loose powders.

Description

Technical Field

[0001] This utility model is a clean working environment maintenance device, belonging to the field of working environment maintenance devices. Background Technology

[0002] During the production of pressed powder and loose powder, a large amount of fine dust is generated in the workshop. This dust not only affects the quality and stability of the products, but also poses a serious threat to the health of workers if they are exposed to the dusty environment for a long time. Therefore, it is particularly important to carry out efficient dust collection and air purification in the production space.

[0003] Commonly available vacuum cleaners only have a single vacuuming function. Their working principle usually relies on the negative pressure generated by a fan to suck dust into the dust collection box. They cannot purify the air they draw in. When these ordinary vacuum cleaners are used in powder and loose powder production workshops, although they can collect some dust, some fine dust will be released back into the air during the vacuuming process. As a result, the air quality in the workshop still cannot meet the production requirements, and the dust pollution problem cannot be fundamentally solved. Directly using air purifiers for vacuuming and purification also has many drawbacks. Air purifiers mainly focus on circulating and purifying indoor air. Their suction power is limited, and their vacuuming efficiency is far lower than that of professional vacuum cleaners. Powder and loose powder production workshops generate a large amount of dust with a high concentration. During the vacuuming process, the air purifier filter is easily clogged by a large amount of dust. Once the filter is clogged, it will not only reduce the purification efficiency of the air purifier, but also significantly shorten the life of the filter, increase equipment maintenance costs, and increase the frequency of filter replacement.

[0004] Furthermore, neither ordinary vacuum cleaners nor air purifiers can accurately remove dust from multiple specific dust-generating points in the production workshop of pressed powder and loose powder. In the production workshop, the dust generation locations of different production stages are relatively fixed and dispersed. For example, processes such as raw material mixing and pressing will continuously generate dust. Ordinary equipment cannot efficiently remove dust from these multiple points, resulting in serious dust accumulation in some areas, which further affects product quality and the production environment. Therefore, it is necessary to design a clean working environment maintenance device. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a clean working environment maintenance device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clean working environment maintenance device, comprising a dust collection cylinder, a filter cabinet at one end of the dust collection cylinder, and a top cover at the top of the dust collection cylinder. An air pump is located at the center of the top cover, and the output end of the air pump is connected to the top of the filter cabinet via an air guide pipe. Dust inlets are provided on both sides of the dust collection cylinder, and dust collection components are connected to the dust inlets. A filter cartridge is installed at the bottom of the top cover, and a cleaning rack is provided around the outer periphery of the filter cartridge. The filter cabinet is internally configured from top to bottom as a filter chamber, a sterilization chamber, and an exhaust chamber. A filter screen is installed inside the filter chamber. Ultraviolet sterilization lamps are installed on both sides inside the sterilization chamber, and an exhaust fan is embedded in the top of the exhaust chamber.

[0007] Furthermore, the dust collector is provided with wheels evenly distributed at the bottom edge of the dust collector, and a dust removal door is provided at the bottom of the dust collector away from the filter cabinet. A control panel is provided on the dust collector above the dust removal door, and push handles are installed on the dust collector on both sides of the control panel.

[0008] Furthermore, a drive motor is installed on the top of the dust collector at the end away from the filter cabinet. A limit ring is fixed on the top of the inner wall of the dust collector, and a turntable is rotatably connected to the limit ring. A gear plate is provided at the bottom of the turntable, and a cleaning frame is fixedly connected to the gear plate. A bevel gear is provided on one side of the bottom of the gear plate to mesh with it, and the output end of the drive motor passes through the side wall of the dust collector and is connected to the bevel gear.

[0009] Furthermore, the air outlet chamber is provided with an air outlet at one end away from the dust collector and on both sides, and the sterilization chamber is hinged with an inspection door at one end away from the dust collector.

[0010] Furthermore, the vacuuming assembly includes a vacuum bucket, a gooseneck tube, a vacuum suction cup, and a vacuum hose. The vacuum bucket has a long rectangular suction port. The vacuum bucket is threadedly connected to the vacuum hose via a snap-fit ​​part, and a retainer is fitted on the snap-fit ​​part. The retainer is connected to the gooseneck tube, and a vacuum suction cup is fixed to the end of the gooseneck tube away from the retainer. A threaded connector that matches the dust inlet is provided at the end of the vacuum hose away from the vacuum bucket.

[0011] Furthermore, the inner diameter of the turntable and the toothed disc is larger than the outer diameter of the filter cartridge, and the central axes of the turntable, the toothed disc and the filter cartridge coincide. The cleaning frame is designed in a "U" shape, and the inner sidewall of the cleaning frame is in contact with the outer wall of the filter cartridge.

[0012] Furthermore, the filter screen is provided in three equally spaced sections, and all three filter screens are inserted into the filter chamber. The three filter screens are arranged from top to bottom as a pre-filter, an activated carbon filter, and a HEPA filter.

[0013] The beneficial effects of this utility model are:

[0014] 1. By combining the dust collector and the filter cabinet, the dust-laden air first undergoes coarse filtration in the dust collector, where larger dust particles settle and fine dust particles are intercepted by the filter cartridge, reducing the dust concentration in the air. Subsequently, the air that has undergone preliminary filtration enters the filter cabinet, where three layers of filters work in a progressive manner to specifically filter and adsorb pollutants and harmful gases of different particle sizes. Ultraviolet sterilization lamps then kill any remaining microorganisms. This multi-stage filtration method avoids high-concentration dust directly impacting the filter cabinet screens, reducing the risk of filter clogging, while ensuring the cleanliness of the output air and meeting the stringent requirements for a high-cleanliness environment in the production of powder cakes and loose powders.

[0015] 2. The dust collection unit features a long rectangular suction port, enabling precise dust collection from multiple specific dust-generating points in powder and loose powder production workshops. Compared to ordinary dust collection equipment, cleaning efficiency is significantly improved. Furthermore, the combination of the vacuum suction cup and the gooseneck tube, which can be freely bent and shaped, allows the dust collection unit to adapt to dust-generating points at different heights, angles, and positions, enhancing the device's applicability in complex production environments. It also allows for flexible fixation of the dust collection position, resulting in better dust collection performance.

[0016] 3. The filter cartridge is equipped with an automatic cleaning mechanism, which can remove surface dust in a timely manner, avoid the problem of decreased filtration efficiency and filter screen clogging caused by dust accumulation, reduce the frequency of manual maintenance, extend the service life of the filter cartridge and other filter screens, and reduce equipment maintenance costs.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a clean working environment maintenance device, including a dust collection cylinder 1, a filter cabinet 2 at one end of the dust collection cylinder 1, and a top cover 4 installed on the top of the dust collection cylinder 1. An air pump 5 is installed at the center of the top cover 4, and the output end of the air pump 5 is connected to the top of the filter cabinet 2 via an air guide pipe 11. Dust inlets 12 are provided on both sides of the dust collection cylinder 1, and dust collection components 6 are connected to the dust inlets 12. A filter cylinder 16 is installed at the bottom of the top cover 4, and a cleaning rack 17 is provided on the outer periphery of the filter cylinder 16. The filter cabinet 2 is configured from top to bottom as a filter chamber 201, a sterilization chamber 202, and an air outlet chamber 203. A filter screen 19 is installed inside the filter chamber 201, and air outlet chambers 203 are provided on both sides inside the sterilization chamber 202. Equipped with an ultraviolet sterilization lamp 20 and an exhaust fan 21 embedded in the top of the air outlet chamber 203, the dust collection cylinder 1 and the filter cabinet 2 are brought together. The dust-laden air is first coarsely filtered in the dust collection cylinder 1, where larger dust particles settle and fine dust particles are intercepted by the filter cartridge 16, reducing the dust concentration in the air. Subsequently, the air that has passed the preliminary filtration enters the filter cabinet 2, where the three-stage filter screen 19 filters the pollutants and harmful gases of different particle sizes in a progressive manner. The ultraviolet sterilization lamp 20 then kills any remaining microorganisms. This graded filtration method avoids high-concentration dust directly impacting the filter screen 19 of the filter cabinet 2, reducing the risk of filter screen 19 clogging, while ensuring the cleanliness of the output air and meeting the stringent requirements of high-cleanliness environment for the production of powder cakes and loose powders.

[0026] For example, the dust collector 1 is provided with wheels 3 evenly distributed at the bottom edge, and a dust removal door 7 is provided at the bottom of the dust collector 1 away from the filter cabinet 2. A control panel 8 is provided on the dust collector 1 above the dust removal door 7, and push handles 9 are installed on the dust collector 1 on both sides of the control panel 8. The design of the wheels 3 and push handles 9 makes it easy for the device to move flexibly in the workshop.

[0027] For example, a drive motor 10 is installed on the top of the end of the dust collector 1 away from the filter cabinet 2. A limit ring 13 is fixed on the top of the inner wall of the dust collector 1, and a turntable 14 is rotatably connected to the limit ring 13. A toothed disc 15 is provided at the bottom of the turntable 14, and a cleaning frame 17 is fixedly connected to the toothed disc 15. A bevel gear 18 that meshes with the bottom of the toothed disc 15 is provided on one side of the bottom of the toothed disc 15, and the output end of the drive motor 10 passes through the side wall of the dust collector 1 and is connected to the bevel gear 18. When it is necessary to clean the dust attached to the surface of the filter cartridge 16, the drive motor 10 is started, and its output end drives the bevel gear 18 to rotate, thereby driving the toothed disc 15 that meshes with it, so that the cleaning frame 17 makes a circular motion around the filter cartridge 16, scraping the dust on the surface of the filter cartridge 16 to the bottom of the dust collector 1, and periodically discharged through the dust removal door 7.

[0028] Please see Figure 1 and Figure 4 The air outlet chamber 203 has an air outlet at one end away from the dust collector 1 and on both sides. The sterilization chamber 202 is hinged to an inspection door at one end away from the dust collector 1. The inspection door design facilitates the inspection and maintenance of the ultraviolet sterilization lamp 20 inside the sterilization chamber 202 and the exhaust fan 21 on the top of the air outlet chamber 203.

[0029] Please see Figure 5 The dust collection assembly 6 includes a dust collection bucket 22, a gooseneck tube 24, a vacuum suction cup 25, and a dust collection hose 26. The suction port of the dust collection bucket 22 is rectangular. The dust collection bucket 22 is threadedly connected to the dust collection hose 26 via a snap-fit ​​part 2201. A snap-fit ​​sleeve 23 is fitted on the snap-fit ​​part 2201. The snap-fit ​​sleeve 23 is connected to the gooseneck tube 24. The vacuum suction cup 25 is fixed to the end of the gooseneck tube 24 away from the snap-fit ​​sleeve 23. The end of the dust collection hose 26 away from the dust collection bucket 22 is provided with a threaded connector 27 that matches the dust inlet 12. The combination of the vacuum suction cup 25 and the gooseneck tube 24 allows the gooseneck tube 24 to be freely bent and shaped, enabling the dust collection assembly 6 to adapt to dust-generating points of different heights, angles, and positions. This enhances the applicability of the device in complex production environments and allows for flexible fixation of the dust collection position.

[0030] Please see Figure 3 The inner diameters of the turntable 14 and the toothed disc 15 are larger than the outer diameter of the filter cartridge 16, and the central axes of the turntable 14, the toothed disc 15 and the filter cartridge 16 coincide. The cleaning frame 17 has a "U" shape design, and the inner side wall of the cleaning frame 17 is in close contact with the outer wall of the filter cartridge 16. The "U" shape and the close contact design between the inner side wall and the outer wall of the filter cartridge 16 allow the cleaning frame 17 to fit tightly against the surface of the filter cartridge 16. Whether it is the front, side or corner of the filter cartridge 16, the cleaning frame 17 can scrape off the attached dust without dead angles, avoid cleaning blind spots, ensure that the dust on the surface of the filter cartridge 16 is efficiently cleaned, and continuously maintain the good filtration performance of the filter cartridge 16.

[0031] Please see Figure 1 and Figure 4Three filter screens 19 are evenly spaced and are inserted into the filter chamber 201. The three filter screens 19 are arranged from top to bottom as a pre-filter, an activated carbon filter, and a HEPA filter. The insertion design greatly simplifies the replacement process of the filter screens 19. In practical applications, the type of filter screen 19 can be flexibly adjusted or different specifications of filter screen 19 can be replaced according to the specific pollution situation and purification needs of the powder cake and loose powder production workshop.

[0032] Detailed Implementation: In use, the vacuum hopper 22, with its elongated rectangular suction port design, can efficiently cover large flat areas and easily reach into narrow crevices, precisely fitting various dust-generating points in the powder and loose powder production workshop. Through the flexible bending characteristics of the gooseneck tube 24, the vacuum suction cup 25 can be fixed at specific dust-generating locations, forming a stable adsorption point. After the air pump 5 is turned on, the negative pressure generated is transmitted to the vacuum hopper 22 through the suction hose 26, drawing dust into the dust collection cylinder 1 through the dust inlet 12. The dust-laden air then enters the dust collection cylinder 1. Afterwards, larger dust particles naturally settle to the bottom of the cylinder under gravity, while finer dust rises with the airflow and is intercepted and filtered by the filter cartridge 16. When it is necessary to clean the dust adhering to the surface of the filter cartridge 16, the drive motor 10 is started, and its output end drives the bevel gear 18 to rotate, which in turn drives the gear disc 15 meshing with it, causing the cleaning frame 17 to move in a circular motion around the filter cartridge 16, scraping the dust on the surface of the filter cartridge 16 to the bottom of the dust collector cylinder 1, and then discharging it through the dust removal door 7. The air, after preliminary filtration by the filter cartridge 16, enters the filter cabinet 2 through the air guide pipe 11. Inside the filter chamber 201, the air passes through the pre-filter, activated carbon filter, and HEPA filter in sequence, filtering large particulate impurities, adsorbing harmful gases and odors, and intercepting fine particulate matter, respectively. Then it enters the sterilization chamber 202, where it is irradiated by ultraviolet sterilization lamps 20 on both sides to kill any remaining bacteria and viruses in the air. Finally, under the action of the exhaust fan 21, the purified air is discharged from the exhaust port of the exhaust chamber 203 and re-enters the workshop environment.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
