[0002] Non-ferrous metals generally refer to all metals other than iron and iron-based alloys, such as light metals like aluminum, magnesium, aluminum alloys, and magnesium alloys; heavy metals like copper, zinc, copper alloys, and zinc alloys; and rare metals. Non-ferrous metals are fundamental materials for national economic development. Most industries, including aviation, aerospace, automotive, machinery manufacturing, power, communications, construction, and home appliances, rely on non-ferrous metal materials for production. With the rapid advancement of modern chemical, agricultural, and scientific technologies, the role of non-ferrous metals in human development is becoming increasingly important. They are not only important strategic resources and essential means of production worldwide, but also indispensable materials for consumer goods in human life.

[0003] During the manufacturing process of non-ferrous metal alloys, such as casting or forging, further grinding, polishing, and finishing are required. These processes generate a significant amount of debris and dust, especially the airborne dust, which can be inhaled by workers, causing serious harm. Even with masks on, the environment still poses a considerable hazard. Existing dust collection devices typically use baghouse dust collectors, but these are expensive, require a large footprint, are prone to clogging, and are unsuitable for high-temperature, sticky, or highly hygroscopic dust. Furthermore, they require frequent filter bag replacements, making them inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide a dust treatment device for non-ferrous metal alloy manufacturing, so as to solve the technical problems existing in the prior art, such as large footprint, easy clogging, and inconvenience of use.

[0017] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0018] It should be noted that, unless otherwise defined, the technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The use of "belonging" in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this invention.

[0019] An embodiment of the dust treatment device for non-ferrous metal alloy manufacturing according to this utility model is as follows: Figures 1-3 As shown, the device includes a housing 1. A transverse partition 2 divides the housing cavity into an upper processing chamber 3 and a lower collection chamber 4. A suction pipe 5 and an exhaust pipe 8 are mounted on the wall of the upper processing chamber. The exhaust pipe is connected to an air pump, and the suction pipe 5 is connected to a dust collection hood 7 via a corrugated pipe 6. A filter screen 9 is installed vertically between the suction pipe and the exhaust pipe in the upper processing chamber to filter metal dust. To prevent metal dust from clogging the filter screen, a drive mechanism 10 is provided on the housing. The drive mechanism has a movable end that extends into the upper processing chamber and can move up and down. The movable end is located upstream of the filter screen and has a cleaning brush 11 mounted on it. The cleaning brush is used to brush the filter screen to remove the metal dust adhering to it, preventing it from clogging the filter screen. A dust discharge port is provided on the transverse partition below the cleaning brush. A movable plate 13 is elastically hinged to the dust discharge port. Here, elastic hinge means that a torsion spring is fitted on the hinge shaft. The movable plate keeps the dust discharge port sealed under the action of the torsion spring, and can automatically reset under the action of the torsion spring even if it is opened. A push rod 12 is provided at the lower end of the cleaning brush 11. The movable plate has an open position where it can be pushed open by the push rod to allow dust to fall, and a closed position where it can be reset to seal the dust discharge port.

[0020] In this embodiment, a vertical partition 19 is provided inside the upper processing chamber, and there is only one vertical partition in this embodiment, which divides the upper processing chamber into two sub-processing chambers. Each sub-processing chamber has a suction pipe, an exhaust pipe, and a drive mechanism on its wall, and each sub-processing chamber has a filter screen, a cleaning brush, and a top rod. In this embodiment, the drive mechanism is an electric push rod. In other embodiments, the drive mechanism can also be a hydraulic cylinder. Each sub-processing chamber has a dust drop outlet and a movable plate on its bottom wall. The advantage of this arrangement is that the dust treatment device of this invention can simultaneously perform dust removal treatment on two devices. In other embodiments, the number of vertical partitions can be selected according to actual needs, or vertical partitions can be omitted, in which case dust removal treatment can be performed on only one device.

[0021] A dust cylinder 14 is installed in the lower collection chamber, located below each dust drop outlet, ensuring that all metal dust falling from the dust drop outlets can fall into the lower dust cylinder for collection. Rollers 15 are installed on the dust cylinder, and a movable door 18 is hinged to the wall of the lower collection chamber 4. Specifically, the lower end of the movable door is hinged to the wall of the lower collection chamber, and a limiting structure is provided between its upper end and the wall of the lower collection chamber. In this embodiment, the limiting structure includes an elastic lock 16 installed on the wall of the lower collection chamber. The elastic lock includes two opposing elastic plates. A latch 17 is provided on the movable door, with a latching part for opening and engaging with the two elastic plates for limiting and locking. When the upper end of the movable door 18 is opened, it contacts the ground to form a ramp supporting the dust cylinder, facilitating the entry and exit of the dust cylinder into the lower collection chamber. To facilitate opening the movable door, a groove is provided on the movable door to act as a handle for easy application of force. In other embodiments, the limiting structure can also be a magnetic adsorption structure. Simply put, a permanent magnet is provided on the housing, and an adsorption component is provided on the movable door for the permanent magnet to magnetically attract. Alternatively, it can be an existing lock lug and latch structure.

[0022] During use, the dust hoods can be fixed in the appropriate positions as needed. This embodiment has two dust hoods, allowing simultaneous dust removal from two manufacturing devices, or either one can be selected for use as needed. When dust removal is required, the air pump is activated, and the metal dust in the air is sucked into the corresponding sub-processing chamber by the vacuum cleaner and trapped by the filter screen. A fixed time can be set for brushing the filter screen, or a fixed time can be set for opening the movable plate via the push rod to allow the dust to fall. Each time the movable plate is opened, it also brushes the filter screen, ensuring that it does not become clogged. The fallen metal dust falls into the dust cylinder in the lower collection chamber. The dust cylinder can be easily pulled out of the lower collection chamber by opening the movable door, or an empty dust cylinder can be pushed into the lower collection chamber, making it convenient to use.
