Description

Technical Field

[0001] This utility model relates to the field of plastic particle processing technology, and in particular to a plastic particle powder dust removal device. Background Technology

[0002] Plastic particles, also known as plastic granules, refer to granular plastics, generally classified into more than 200 types, with further subdivisions reaching thousands. Common plastic particles include general-purpose plastics, engineering plastics, and specialty plastics. General-purpose plastics include polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, and polyurethane, while engineering plastics include nylon, polytetrafluoroethylene, polyoxymethylene, and polycarbonate.

[0003] Before packaging, a dust removal process is usually required to ensure the cleanliness and quality of the product. Currently, the commonly used dust removal method is to use an air blowing valve, which discharges the dust to the outside. Existing technology uses a cyclone separator to treat the dust-containing air. However, since the dust discharge point of the cyclone separator continuously discharges dust, the dust collection box is prone to becoming full during continuous processing. At this time, it is necessary to shut down the entire dust removal section and clean it, which obviously reduces the actual efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dust removal device for plastic particles and powders. In actual use, this dust removal device effectively improves the efficiency of mechanical dust removal. In addition, it is equipped with a stirring mechanism to further enhance the comprehensiveness of dust removal.

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

[0006] A plastic particle powder dust removal device includes a processing box with a feed inlet at the top and a discharge outlet at the bottom; an agitation mechanism for agitating the plastic particles, the agitation mechanism including a drive motor mounted on the upper end of the processing box, the output shaft of the drive motor extending into the processing box and having multiple agitation shafts mounted thereon; and a dust removal mechanism that cooperates with the agitation mechanism.

[0007] Preferably, a base frame is installed at the lower end of the processing box.

[0008] Preferably, both the feed inlet and the discharge outlet are equipped with sealing plates.

[0009] Preferably, the dust removal mechanism includes a hollow plate fixedly connected to the inside of the right side of the processing box, with multiple exhaust vents on the left side wall of the hollow plate, and a high-pressure air pump installed on the right side of the processing box, the exhaust end of the high-pressure air pump being connected to the inside of the hollow plate.

[0010] Preferably, a cyclone separator is installed at the upper end of the processing box, and the air inlet pipe of the cyclone separator is connected to the inside of the processing box.

[0011] Preferably, the upper end of the processing box is provided with a chute, and two slidable rectangular collection boxes are placed in the chute. Each rectangular collection box has a collection port on its inner top, and the rectangular collection box on the right side abuts against the ash discharge port of the cyclone separator.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By combining the high-pressure airflow generated by the high-pressure air pump with the rotational motion of the agitator shaft, efficient removal of dust from the surface of plastic particles is achieved. The high-pressure airflow is evenly discharged from multiple exhaust ports inside the hollow plate, effectively dispersing and carrying dust particles. The particles are then separated by the cyclone separator through the air inlet pipe, and finally, the clean air is discharged to the outside, while the dust is effectively collected, greatly improving dust removal efficiency and the integrity of dust collection.

[0014] 2. If the collection box is full of dust during a continuous dust removal operation, the rectangular collection box on the left can be pushed to the right until the rectangular collection box on the right contacts the right side wall of the slide, thus replacing the rectangular collection box without stopping the machine, which improves the overall efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-3A plastic particle powder dust removal device includes a processing box 1, a base frame 2 installed at the lower end of the processing box 1, a feed inlet 4 provided at the top inside the processing box 1, a discharge outlet 8 provided at the bottom inside the processing box 1, and a sealing plate installed on both the feed inlet 4 and the discharge outlet 8.

[0021] It also includes an agitation mechanism for agitating plastic particles. The agitation mechanism includes a drive motor 7 mounted on the upper end of the processing tank 1. The output shaft of the drive motor 7 extends into the processing tank 1 and is equipped with multiple agitation shafts 9.

[0022] The system also includes a dust removal mechanism that works in conjunction with a stirring mechanism. The dust removal mechanism includes a hollow plate 10 fixedly connected to the inside of the right side of the processing box 1. Multiple exhaust ports 11 are provided on the left side wall of the hollow plate 10. The diameter of the exhaust ports 11 is small to prevent dust from entering the interior of the hollow plate 10. A high-pressure air pump 3 is installed on the right side of the processing box 1. The exhaust end of the high-pressure air pump 3 is connected to the interior of the hollow plate 10. A cyclone separator 5 is installed at the top of the processing box 1. An annular sealing gasket is installed at the ash discharge port of the cyclone separator 5. The air inlet pipe 6 of the cyclone separator 5 is connected to the interior of the processing box 1.

[0023] The upper end of the processing box 1 is provided with a chute 12, and two sliding rectangular collection boxes 13 are placed in the chute 12. Each rectangular collection box 13 has a collection port 14 on its inner top. The rectangular collection box 13 on the right side abuts against the ash discharge port of the cyclone separator 5.

[0024] In this invention, during use, plastic particles to be dusted are placed into the feed inlet 4 (the amount of plastic particles is one-quarter of the filling volume of the processing box 1), and then the feed inlet 4 is sealed. At the same time as starting the drive motor 7, the high-pressure air pump 3 is started. After the high-pressure air pump 3 starts, the high-pressure airflow enters the hollow plate 10 and is discharged from multiple exhaust ports 11, blowing off the dust on the plastic particles. The dust particles move with the airflow and enter the cyclone separator 5 through the air inlet pipe 6. Finally, the dust particles are discharged to the outside from the air outlet of the cyclone separator 5. The start of the drive motor 7 drives multiple stirring shafts 9 to rotate, thereby making the plastic particles move and the gaps between the plastic particles change continuously, so that the dust removal is more comprehensive. After the dust removal is completed, the discharge port 8 is opened to discharge the plastic particles.

[0025] It should be noted that during the above process, the dust discharged by the cyclone separator 5 will fall into the rectangular collection box 13 on the right. If the rectangular collection box 13 is full of dust during a continuous dust removal operation, the rectangular collection box 13 on the left can be pushed to the right until the rectangular collection box 13 on the right contacts the right side wall of the slide 12 to complete the replacement of the rectangular collection box 13. No machine shutdown is required, which improves the overall efficiency.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
