Description

Technical Field

[0001] This utility model relates to a portable dust collector. Background Technology

[0002] A brush machine is typically used to remove burrs from wheel hub spokes. Brushing off the burrs generates a lot of aluminum powder. Although the brush machine has an area for collecting aluminum powder, dust still accumulates significantly at the brush machine, requiring regular cleaning by a dedicated person.

[0003] Portable dust collectors are typically used to remove dust from the brush machine. These collectors consist of a frame with wheels underneath and a fan mounted on the frame. To prevent aluminum powder and other dust from entering the fan, a filter is usually installed at the fan location. This filter needs to be replaced or cleaned regularly, which is quite inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a portable dust collector that is easy to use and reduces the frequency of filter cleaning and replacement.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable dust collector, comprising a frame and wheels disposed on the lower side of the frame, a filter element disposed on the frame, and three independent chambers disposed from top to bottom in the frame, wherein a power component, a filter component, and a dust collection component are disposed sequentially from top to bottom in the three chambers, an air inlet disposed in the chamber corresponding to the filter component, the air inlet disposed of a pipe joint, and an air outlet disposed in the chamber corresponding to the power component, the filter component comprising the filter element disposed vertically, the upper and lower ends of the filter element being connected to the chamber of the power component and the chamber of the dust collection component respectively, and the power component comprising a pulse backflushing mechanism.

[0006] The frame is divided into three independent chambers from top to bottom: a power component chamber, a filter component chamber, and a dust collection component chamber. This layered structure allows each functional component to operate independently without interference, facilitating maintenance and management, and also improving dust collection efficiency. The filter element is vertically arranged, with its upper and lower ends connected to the chambers of the power component and the dust collection component, respectively. This design allows air to pass smoothly through the filter element for filtration, while also facilitating the falling of dust into the dust collection component under gravity, thus improving filtration efficiency and dust collection effect. The power component includes a pulse backflushing mechanism, which periodically backflushes the filter element, removing dust from its surface, thereby extending its service life, reducing the frequency of filter element cleaning and replacement, and improving the operating efficiency and economy of the equipment.

[0007] Preferably, the power assembly further includes a fan and a duct that cooperate with each other. The air outlet is located at one end of the duct, and the other end of the duct is connected to the chamber where the power assembly is located. The fan provides power to discharge filtered air through the duct. This structure ensures smooth air discharge, and by rationally designing the layout of the duct, the airflow path can be optimized, thereby improving the performance of the dust collector of this invention.

[0008] Preferably, the chamber at the power assembly is divided into a first chamber and a second chamber. The fan and duct are located in the first chamber, and the pulse backflushing mechanism is located in the second chamber. The second chamber is directly connected to the inner cavity of the filter element, and the end of the duct away from the air outlet is connected to the second chamber. This separation and connection method allows the fan and pulse backflushing mechanism to operate independently without interfering with each other, while ensuring that the airflow can pass smoothly through the filter element and the pulse backflushing mechanism, thus improving the stability and reliability of this invention.

[0009] Preferably, the number of filter elements is at least two, with one filter element offset from the air inlet and the other filter element located in the air inlet direction. This arrangement increases the filtration area and improves filtration efficiency. Furthermore, by rationally arranging the filter elements, excessive dust concentration on a single filter element can be avoided, extending the filter element's lifespan.

[0010] Preferably, the frame has an explosion-proof plate on the side wall corresponding to the filter assembly. This plate can automatically rupture and release pressure when the internal pressure of the dust collector becomes too high, preventing explosions and other safety accidents caused by excessive pressure, thus improving the safety of the invention during use.

[0011] Preferably, the dust collection assembly includes a dust collection box, and the lower end of the filter element extends into the chamber of the dust collection assembly. The dust collection box facilitates dust collection and cleaning.

[0012] Preferably, the lower end of the frame is provided with an openable / closable window, and the dust collection box is slidably disposed within the chamber of the dust collection component of the frame. The openable / closable window facilitates the operator to open and close the chamber of the dust collection component, making it convenient for maintenance and cleaning of the dust collection component. The sliding arrangement of the dust collection box allows for easy removal and placement, facilitating cleaning and replacement, and improving the convenience of using this invention.

[0013] This invention has the advantages of better stability and safety in use, and can reduce the frequency of filter cleaning and replacement. Attached Figure Description
