Description

Technical Field

[0001] This utility model relates to a plastic powder filtration device, and more particularly to a novel plastic powder filtration device. Background Technology

[0002] Powder coating, also known as electrostatic powder coating, is a widely adopted decorative technique for metal surface treatment since the 1980s. Compared to ordinary spray painting, it offers advantages such as advanced technology, energy efficiency, safety, reliability, and vibrant colors. Therefore, it is frequently used in light industry and home decoration. Its working principle involves charging plastic powder through a high-voltage electrostatic device. Under the influence of the electric field, the coating is sprayed onto the workpiece surface, where the powder is evenly adsorbed, forming a powdery coating. After high-temperature baking, this powdery coating flows and solidifies, melting the plastic particles into a dense final protective coating with varying effects, firmly adhering to the workpiece surface. Powder recycling is a necessary step in the powder coating process to save on sealing materials and maintain a clean working environment. Current methods involve centralized collection, filtration, and reuse of powder, which is inefficient. In powder coating operations requiring frequent powder replacement, a rapid powder recycling and filtration device is needed. Utility Model Content

[0003] This utility model discloses a novel plastic powder filtration device, comprising: a movable feeding pipe section, a fixed receiving pipe section, a hinge, and a filter screen. The movable feeding pipe section and the fixed receiving pipe section are connected by the hinge. The filter screen is installed at the filter screen mounting position in the fixed receiving pipe section. The fixed receiving pipe section is provided with a back-blowing port, which is connected to an external high-pressure air pump. The high-pressure airflow from the back-blowing port flows from below the filter screen towards...

[0004] The filter screen is blown upwards. This utility model solves the problem of the lack of a fast-filtering plastic powder recycling device in existing plastic powder recycling work by setting a filter screen at the filter screen installation position in the fixed receiving pipe section, and using high-pressure airflow from the back blow port to blow away the impurities blocking the filter screen, so as to ensure that the plastic powder can be efficiently filtered by the filter screen and enter the fixed receiving pipe section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel plastic powder filtration device includes: a movable feeding pipe section, a fixed receiving pipe section, and a hinge.

[0007] The filter screen, the movable feeding pipe section, and the fixed receiving pipe section are connected by a hinge. The filter screen is installed at the filter screen mounting position of the fixed receiving pipe section. The fixed receiving pipe section is equipped with a back-blowing port, which is connected to an external high-pressure air pump. The high-pressure airflow from the back-blowing port blows from the bottom of the filter screen to the top of the filter screen.

[0008] Further, a feed pipe interface is provided at the upper end of the movable feed pipe section, which is connected to the feed pipe, and a feed hopper is provided at the upper end of the movable feed pipe section.

[0009] Further, a receiving hopper is provided at the upper end of the fixed receiving pipe section, and a receiving pipe interface is provided at the lower end of the fixed receiving pipe section, with the receiving pipe interface connected to the receiving pipe.

[0010] Further, the lower end face of the feed hopper is connected to the upper end face of the receiving hopper.

[0011] Further, the combination of the active feeding pipe section and the fixed receiving pipe section is spindle-shaped.

[0012] This invention solves the problem of the lack of a fast-filtering plastic powder recycling device in existing plastic powder recycling processes by installing a filter screen at the filter screen installation position in the fixed receiving pipe section, and using a high-pressure airflow from the back-blowing port to blow away impurities blocking the filter screen to ensure that the plastic powder can be efficiently filtered by the filter screen and enter the fixed receiving pipe section.

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

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.
