Description

Technical Field

[0001] This utility model relates to the field of industrial cleaning equipment technology, specifically an industrial vacuum cleaner with an anti-clogging air inlet. Background Technology

[0002] In industrial production scenarios, industrial vacuum cleaners, as key cleaning equipment, need to continuously handle impurities in various forms such as metal shavings, plastic particles, and dust. The unobstructedness of their air inlets and connected pipes directly determines the cleaning efficiency and equipment stability.

[0003] Most existing industrial vacuum cleaners rely on a single filter to intercept inhaled impurities, but this design has significant drawbacks: Firstly, a single filter cannot simultaneously meet the filtration needs of impurities of different particle sizes. Larger debris can easily get stuck in the filter pores or air inlet, while fine dust can easily penetrate the filter and accumulate in subsequent pipes and inside the suction components. Over time, this can lead to air inlet blockage, reduced suction power, and even motor overload damage. Secondly, traditional filters are often fixed inside the equipment with multiple bolts. Disassembly, cleaning, or replacement requires disassembling the air intake structure, which is cumbersome and time-consuming. Especially in scenarios requiring high-frequency cleaning, such as production lines, frequent downtime for maintenance can severely impact production progress.

[0004] In addition, although some vacuum cleaners have added primary filter components, they are not optimized for airflow direction. Impurities tend to accumulate disorderly on the surface of the filter components, which not only speeds up the clogging process, but also further reduces the vacuuming efficiency due to airflow turbulence.

[0005] Therefore, it is necessary to propose an industrial vacuum cleaner that prevents the air inlet from clogging. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an industrial vacuum cleaner with an anti-clogging air inlet, which has the advantages of [previous technology] and solves the problems mentioned in the background art.

[0007] This utility model provides the following technical solution: an industrial vacuum cleaner with an anti-clogging air inlet, comprising a vacuum cleaner body: The side of the vacuum cleaner body is connected to an air inlet pipe one, and the other end of the air inlet pipe one is connected to an air inlet pipe two by bolts. The other end of the air inlet pipe two is connected to an air inlet frame. A connecting arm is fixedly installed on the side of the air inlet frame, and the connecting arm is connected to the side of the vacuum cleaner body by bolts. A connecting slot is provided on the side of the air inlet frame. A filter screen is inserted into the connecting slot. The filter screen is directly opposite the connection position between the air inlet pipe and the air inlet frame. A conical air duct is fixedly installed inside the air inlet pipe. A supporting circular plate is provided inside the end of the air inlet pipe. A connecting circular plate is attached to the lower surface of the supporting circular plate. A conical filter is fixedly installed inside the connecting circular plate. The outer surface of the end of the conical filter is attached to the inside of the supporting circular plate.

[0008] Preferably, at least one set of docking grooves are provided at equal intervals on the end cavity wall of the second air inlet pipe, a portion of the outer surface of the supporting circular plate is docked with the inside of the docking groove, and the upper surface of the supporting circular plate is in contact with the end surface of the first air inlet pipe.

[0009] Preferably, a second magnet is fixedly installed on the lower surface of the supporting circular plate, a first magnet is fixedly installed on the upper surface of the connecting circular plate, the second magnet is magnetically connected to the first magnet, at least one set of insert rods are fixedly installed at equal intervals on the lower surface of the supporting circular plate, and at least one set of slots are opened at equal intervals on the upper surface of the connecting circular plate, and the insert rods are inserted into the slots.

[0010] Preferably, side grooves are provided on both sides of the second air inlet pipe, and a second dust collection box is connected to the inside of the side groove. A slot is provided at the adjacent end of the second dust collection box, and a U-shaped plug is inserted into the inside of the slot. A nut is threaded to the end of the U-shaped plug, and the upper surface of the nut is in contact with the lower surface of the second dust collection box.

[0011] Preferably, a drive telescopic component is fixedly installed at both ends of one side of the air inlet frame, and a pusher plate is fixedly installed at the output end of the drive telescopic component, with the upper surface of the pusher plate placed on the lower surface of the filter screen.

[0012] Preferably, a second connecting slot is provided on the other side of the air inlet frame, and a dust collection box is connected inside the second connecting slot. The dust collection box is installed to the air inlet frame by bolts, and the filter is installed to the air inlet frame by bolts.

[0013] Preferably, the conical air duct and the conical filter are on the same central axis, and the conical air duct and the conical filter are arranged sequentially from bottom to top inside the air inlet pipe 2, and both the conical air duct and the conical filter are arranged to be wider at the bottom and narrower at the top.

[0014] Preferably, the side groove is located on the outer side of the conical air duct.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This type of industrial vacuum cleaner with an anti-clogging air inlet utilizes a dual filtration structure formed by the filter screen of the air inlet frame and the conical filter cartridge of the air inlet duct. Larger impurities are first intercepted by the filter screen, and then fine dust is filtered a second time by the conical filter cartridge. This significantly reduces the total amount of impurities entering the vacuum cleaner body, lowering the probability of clogging at the air inlet and internal pipes from the source. Furthermore, the coaxial design of the conical air duct and the conical filter cartridge, with a wider bottom and narrower top, optimizes airflow and prevents impurities from accumulating on the surface of the filter components, further enhancing the anti-clogging effect. 2. This type of industrial vacuum cleaner with an anti-clogging air inlet uses a filter screen that is inserted into a connecting slot and fixed with bolts. The conical filter cartridge is quickly assembled by magnetic adsorption between the connecting circular plate and the supporting circular plate, as well as by insertion of a rod. No complicated tools are required for disassembly, making it easy to clean or replace the filter components regularly. At the same time, the dust collection boxes on both sides of the air inlet pipe can collect some of the filtered impurities. They can be quickly removed for cleaning by using U-shaped blocks and nuts, reducing the frequency of overall disassembly and maintenance and lowering labor and time costs.

[0016] 3. This type of industrial vacuum cleaner with anti-clogging air inlet has a drive telescopic component on the side of the air inlet frame that can move the pusher plate along the lower surface of the filter screen. It can actively push the impurities accumulated on the filter screen into the dust collection box, avoiding the impurities from clogging the filter screen pores and affecting the air intake efficiency. It ensures that the vacuum cleaner maintains stable suction and cleaning ability during long-term operation, and is suitable for continuous and high-intensity cleaning needs in industrial scenarios.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Please see Figure 1-7 An industrial vacuum cleaner with an anti-clogging air inlet, comprising a vacuum cleaner body 1: The side of the vacuum cleaner body 1 is connected to an air inlet pipe 4. The other end of the air inlet pipe 4 is connected to an air inlet pipe 5 by bolts. The other end of the air inlet pipe 5 is connected to an air inlet frame 2. A connecting arm 3 is fixedly installed on the side of the air inlet frame 2. The connecting arm 3 is connected to the side of the vacuum cleaner body 1 by bolts. The vacuum cleaner body 1 generates negative pressure suction, drawing impurities in through the air inlet frame 2, and then sequentially through air inlet pipe 2 5 and air inlet pipe 1 4 into the vacuum cleaner body 1. The connecting arm 3 secures the air inlet frame 2 to the vacuum cleaner body 1 with bolts, preventing displacement of the air inlet frame 2 under negative pressure. Simultaneously, air inlet pipe 1 4 and air inlet pipe 2 5 are connected by bolts to ensure the piping is sealed. A connecting slot 221 is provided on the side of the air inlet frame 2. A filter screen 220 is inserted into the connecting slot 221. The filter screen 220 is directly opposite the connection position between the air inlet pipe 5 and the air inlet frame 2. A conical air duct 540 is fixedly installed inside the air inlet pipe 5. A supporting circular plate 560 is provided inside the end of the air inlet pipe 5. A connecting circular plate 551 is attached to the lower surface of the supporting circular plate 560. A conical filter cartridge 550 is fixedly installed inside the connecting circular plate 551. The outer surface of the end of the conical filter cartridge 550 is attached to the inside of the supporting circular plate 560. After impurities enter the air inlet frame 2, they are first intercepted by the filter screen 220, which intercepts larger particles such as metal shavings and plastic pieces. The airflow after preliminary filtration carries fine dust into the second air inlet pipe 5. The conical air duct 540 gathers the dispersed airflow and guides it to the surface of the conical filter cartridge 550, where the fine dust is filtered a second time. The supporting circular plate 560, through its cooperation with the second air inlet pipe 5, provides installation support for the connecting circular plate 551 and the conical filter cartridge 550. The end of the conical filter cartridge 550 is in contact with the supporting circular plate 560 to prevent unfiltered airflow from passing through the gaps.

[0022] Specifically, the dual-filtration structure of filter screen 220 and conical filter cartridge 550 reduces the entry of impurities of different particle sizes into the vacuum cleaner body 1 from the source, reducing the risk of blockage in the air inlet and internal pipes; the conical air duct 540 improves filtration efficiency by concentrating air, and the cooperation between the supporting circular plate 560 and the connecting circular plate 551 ensures stable installation of the filter components and no airflow leakage.

[0023] like Figure 7 As shown, in this embodiment, at least one set of mating grooves 570 are equidistantly provided on the end cavity wall of the second air inlet pipe 5. Part of the outer surface of the supporting circular plate 560 is mated with the inside of the mating groove 570, and the upper surface of the supporting circular plate 560 is in contact with the end surface of the first air inlet pipe 4. When installing the bearing circular plate 560, its outer surface is aligned with the mating groove 570 of the second air inlet pipe 5 to achieve radial positioning; when installing the first air inlet pipe 4, its end surface is attached to the upper surface of the bearing circular plate 560, and the bearing circular plate 560 is axially compressed and fixed by bolt connection between the first air inlet pipe 4 and the second air inlet pipe 5.

[0024] Specifically, the positioning and fixing of the bearing circular plate 560 can be completed without additional fasteners, simplifying the assembly process; at the same time, it ensures that the bearing circular plate 560 does not shift under the impact of airflow, ensuring the stability of the filtration position of the conical filter cartridge 550.

[0025] like Figure 5-6 As shown, in this embodiment, a second magnet 561 is fixedly installed on the lower surface of the supporting circular plate 560, and a first magnet 552 is fixedly installed on the upper surface of the connecting circular plate 551. The second magnet 561 and the first magnet 552 are magnetically connected. At least one set of insert rods 562 are fixedly installed at equal intervals on the lower surface of the supporting circular plate 560, and at least one set of slots 553 are opened at equal intervals on the upper surface of the connecting circular plate 551. The insert rods 562 are inserted into the slots 553. When assembling the conical filter cartridge 550, the slot 553 of the connecting circular plate 551 is aligned with the insertion rod 562 of the supporting circular plate 560 and inserted to achieve circumferential anti-rotation positioning; during the insertion process, magnet one 552 and magnet two 561 are magnetically attracted and adhered, completing the rapid fixation of the connecting circular plate 551 and the supporting circular plate 560.

[0026] Specifically, the insertion rod 562 and the slot 553 work together to prevent the conical filter cartridge 550 from rotating with the airflow and avoid wear on the filter surface; the magnetic adsorption design allows the conical filter cartridge 550 to be disassembled and assembled without tools, which is convenient for regular cleaning or replacement and reduces maintenance costs.

[0027] like Figure 3-4 As shown, in this embodiment, side grooves 510 are provided on both sides of the air inlet pipe 5. A dust collection box 520 is connected to the inside of the side grooves 510. A slot 521 is provided at the adjacent end of the dust collection box 520. A U-shaped plug 530 is inserted into the slot 521. A nut 531 is threaded to the end of the U-shaped plug 530. The upper surface of the nut 531 is in contact with the lower surface of the dust collection box 520. In the airflow gathered by the conical air duct 540, some heavier impurities are separated from the airflow trajectory and fall into the dust collection boxes 520 on both sides due to gravity and centrifugal force of the airflow. The dust collection boxes 520 are connected to the air inlet pipe 5 through the side groove 510. The U-shaped insert 530 passes through the slots 521 of the two dust collection boxes 520. Tightening the nut 531 can fix the dust collection boxes 520 in the side groove 510.

[0028] Specifically, some impurities are collected in advance to reduce the filtration load of the conical filter cartridge 550 and extend its cleaning cycle; the dust collection box 520 is quickly fixed to the nut 531 by the U-shaped plug 530, and can be pulled out by simply unscrewing the nut 531 when disassembling and cleaning, which is convenient and does not require disassembling the air inlet pipe 5.

[0029] like Figure 1-2 As shown, in this embodiment, drive telescopic components 210 are fixedly installed at both ends of one side of the air inlet frame 2. A pusher plate 211 is fixedly installed at the output end of the drive telescopic component 210, and the upper surface of the pusher plate 211 is placed on the lower surface of the filter screen 220. When a lot of impurities accumulate on the surface of the filter screen 220, the drive telescopic component 210 is energized to extend and retract, causing the pusher plate 211 to move horizontally along the lower surface of the filter screen 220, pushing the accumulated impurities on the filter screen 220 to one side.

[0030] Specifically, it actively cleans impurities from the surface of filter 220 to prevent impurities from clogging the pores of filter 220 and causing a decrease in air intake efficiency, ensuring that the vacuum cleaner maintains stable suction power continuously; there is no need to stop the machine to manually clean filter 220, which is suitable for the needs of long-term continuous operation in industrial scenarios.

[0031] like Figure 1-2 As shown, in this embodiment, a connecting slot 231 is provided on the other side of the air inlet frame 2. A dust collection box 230 is connected inside the connecting slot 231. The dust collection box 230 is installed to the air inlet frame 2 by bolts. The filter screen 220 is installed to the air inlet frame 2 by bolts. The impurities pushed by the pusher plate 211 move along the surface of the filter screen 220 and eventually fall into the dust collection box 230. The filter screen 220 is fixed to the connecting slot 221 by bolts, and the dust collection box 230 is fixed to the connecting slot 231 by bolts to ensure that the two do not loosen during equipment operation.

[0032] Specifically, the dust collection box 230 collects large particles of impurities intercepted by the filter 220, preventing impurities from scattering and causing secondary pollution; the bolt-fixed filter 220 and dust collection box 230 not only ensure stable installation, but can also be disassembled for deep cleaning or replacement when needed.

[0033] like Figure 5 As shown, in this embodiment, the conical air duct 540 and the conical filter cartridge 550 are located on the same central axis. The conical air duct 540 and the conical filter cartridge 550 are arranged sequentially from bottom to top inside the air inlet pipe 5. Both the conical air duct 540 and the conical filter cartridge 550 are arranged with a wider bottom and a narrower top. Airflow enters from the lower part of the air inlet duct 2 5, and is guided by the conical air duct 540 which is wider at the bottom and narrower at the top. The airflow cross-section gradually decreases and the flow velocity increases, forming a stable columnar airflow that is transported upward. The columnar airflow acts precisely on the coaxial conical filter cartridge 550. Impurities adhere to the lower wide and upper narrow surface of the conical filter cartridge 550 due to inertia, while the clean airflow passes through the filter cartridge and enters the air inlet duct 1 4.

[0034] Specifically, the coaxial design and conical structure optimize the airflow direction, avoiding airflow turbulence that causes impurities to accumulate on the inner wall of the air inlet duct 25; at the same time, the difference in airflow velocity is used to improve the impurity separation efficiency and reduce the clogging speed of the conical filter cartridge 550.

[0035] like Figure 4-5 As shown, in this embodiment, the side groove 510 is located on the outer side of the conical air duct 540. The inner wall of the air inlet pipe 2 5 on the outer side of the conical air duct 540 forms an annular space. Heavier impurities in the airflow move into the annular space under the action of centrifugal force and eventually fall into the dust collection box 2 520 through the side groove 510, thus achieving the separation of impurities from the airflow.

[0036] Specifically, the side groove 510 is positioned to maximize the collection of heavier impurities, further reducing the filtration pressure on the conical filter cartridge 550 and extending the overall maintenance cycle of the equipment.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
