Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and more specifically, to a mobile filtration and dust removal device. Background Technology

[0002] Dust pollution is prevalent and poses serious risks in numerous scenarios, including industrial production, construction, and daily life. It not only affects air quality and harms human health but can also damage precision equipment, reducing production efficiency and product quality. Therefore, efficient and convenient dust removal equipment is urgently needed. While various dust removal devices exist on the market, they suffer from several shortcomings. Some devices rely solely on a single filter cartridge for dust removal, resulting in limited airflow filtration and failing to meet ideal dust removal standards. Furthermore, dust easily accumulates on the filter surface during filtration, clogging the pores, increasing equipment resistance, energy consumption, and shortening filter lifespan, thus increasing operating costs. In addition, existing dust removal equipment is poorly designed for cleaning filter dust, allowing cleaned dust to be easily carried back to the filter surface by the airflow, causing secondary pollution. Simultaneously, some devices have unreasonable structural designs and poor stability, easily wobbling or even tipping over during movement, affecting user experience and safety, requiring urgent improvement. Therefore, we propose a portable dust removal filtration device. Utility Model Content

[0003] In view of the above-mentioned technical problems in related technologies, this utility model provides a mobile filtration and dust removal device that can solve the above problems.

[0004] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:

[0005] A portable dust removal and filtration device includes an outer shell, a lower sealing plate and an upper sealing plate fixed inside the outer shell. A primary filter element is bolted to the left side of the lower sealing plate, and a high-efficiency filter element is bolted to the right side of the upper sealing plate. A bushing is rotatably mounted in the middle of both the primary and high-efficiency filter elements. The bottom of the bushing is connected to a brush body by screws. A micro motor that drives the bushing to rotate is mounted above the lower and upper sealing plates. A dust collection tray is mounted below both the primary and high-efficiency filter elements. A negative pressure fan is mounted at the top inside the outer shell. Dust suction ports are opened around the bottom of the outer shell. Stainless steel filter screens are bolted to the surface of the dust suction ports. Several casters are bolted to the bottom of the outer shell.

[0006] Furthermore, both the pre-filter assembly and the high-efficiency filter assembly include a circular frame, a support frame fixed inside the circular frame, a bearing body located in the middle of the support frame, and a filter element fixed inside the circular frame.

[0007] Furthermore, an annular seat is fitted around the outside of the ash receiving tray, and the annular seat is fixed to the inner wall surface of the outer shell.

[0008] Furthermore, both sides of the bottom of the outer shell are integrally formed with sloping surfaces, and the corners of the sloping surfaces are integrally formed with rounded chamfers.

[0009] Furthermore, a window is bolted to one side of the outer casing, located 5cm below the high-efficiency filter core assembly, and a sealing plate is installed outside the window.

[0010] Furthermore, a handrail is provided on the surface of the outer shell, an anti-collision rubber ring is fixedly installed on the top edge of the outer shell, and an exhaust mesh cover is installed at the center of the top of the outer shell by bolts.

[0011] The beneficial effects of this utility model are as follows: The negative pressure fan and the primary and high efficiency filter cores of this application perform airflow circulation filtration to achieve the dust removal effect. Through structural design, the brush body is assembled on the air inlet end surface of the filter core. The brush body brushes away the dust on the surface of the filter core, and the dust collection tray catches the brushed dust, preventing the subsequent airflow from carrying the dust to the surface of the filter core. The structure of the dust collection tray, which is wide at the top and narrow at the bottom, is conducive to concentrating the dust at the bottom of the dust collection tray.

[0012] The outer casing has a narrow top and a wide ramp at the bottom, which helps to stabilize the chassis when the lifting device is moved. Attached Figure Description
