Description

Technical Field

[0001] This utility model relates to the field of pneumatic conveying technology, and in particular to a pneumatic conveying device for powder coatings. Background Art

[0002] Powder coatings are solid powdered synthetic resin coatings composed of solid resin, pigments, fillers, and additives. Powder coatings are completely different from ordinary coatings. They exist in the form of fine powder and can be conveyed by pneumatic conveying, also known as airflow conveying. Pneumatic conveying utilizes the energy of airflow to transport granular materials along the airflow direction in a closed pipeline.

[0003] In existing technologies, during pneumatic conveying, the conveying pipe can become damp due to external weather conditions over time. During the conveying process, powder coating can stick to the inside of the conveying pipe, resulting in incomplete conveying. It is difficult to clean the powder coating stuck inside the conveying pipe, which makes the conveying effect of the device less than ideal. In addition, the inside of the conveying pipe needs to be kept dry in rainy weather. Therefore, we need to innovate the existing pneumatic conveying device. Utility Model Content

[0024] Specifically: The material tank 4 is fixed by the support frame 3, so that the support frame 3 can transport the powder coating more stably. The inner tube 6 is embedded inside the outer tube 5, so that the powder coating can be transported better.

[0025] In one embodiment, the output end of the fan 2 is fixedly installed with a first connection port 201 and a second connection port 202. The surface of one end of the outer tube 5 is embedded in the inner wall of the first connection port 201, and the inner wall of one end of the inner tube 6 is sleeved on the surface of the second connection port 202.

[0026] Specifically: the outer tube 5 is embedded in the inner wall of the first connection port 201, and the inner wall of the inner tube 6 is fitted onto the surface of the second connection port 202, so that the outer tube 5 and the inner tube 6 can be better connected to the output end of the fan 2, making the airflow of the fan 2 more stable when it blows air.

[0027] In one embodiment, a threaded block 7 is fixedly installed on the surface of one end of the inner tube 6, and a threaded groove 501 is opened on the inner wall of the outer tube 5. The threaded surface of the threaded block 7 is threaded into the inner wall of the threaded groove 501. A threaded groove 10 is opened on the inner wall of the connecting block 9, and a connecting block 11 is threaded into the inner wall of the threaded groove 10.

[0028] Specifically: the threaded connection between threaded groove 501 and threaded block 7 allows the inner tube 6 to be more stably connected to the inside of the outer tube 5; the threaded connection between threaded groove 10 and connecting block 11 allows the two sections of inner tube 6 to be better connected together.

[0029] In one embodiment, a sealing ring 8 is fitted on the surface of the threaded block 7, and a sealing ring 12 is fitted on the surface of the connecting block 11.

[0030] Specifically: the connection between the outer tube 5 and the inner tube 6 is made more airtight by sealing ring 8, and the connection between the threaded groove 10 and the connecting block 11 is made more airtight by sealing ring 12.

[0031] In one embodiment, a controller 13 is fixedly installed on one side of the support frame 3, buttons 14 are fixedly installed at equal intervals on the surface of the controller 13, and connecting wires 15 are fixedly installed on the bottom of the controller 13.

[0032] Specifically: By pressing the button 14 fixedly installed on the controller 13, some data on the device can be adjusted to make the device more perfect.

One end of the outer tube 5 is embedded in the inner wall of connection port 201, and the inner wall of one end of the inner tube 6 is fitted onto the surface of connection port 202, allowing the outer tube 5 and inner tube 6 to connect better to the output end of the blower 2. By turning the knob 16, the powder coating inside the material tank 4 falls into the inner tube 6, and the air blown by the blower 2 transports the powder coating. After the device is used, the connecting blocks 1 and 2 are separated by rotating them, and a section of the inner tube 6 is unscrewed from inside the outer tube 5 by rotating the connecting block 1. Rotating the connecting block 11 causes the other inner tube 6 to unscrew, making it easier to clean the inner tube 6 and ensuring its interior is clean and tidy. After cleaning, the inner tube 6 is screwed back into the outer tube 5, making the device cleaner and facilitating the cleaning of the conveying pipe. When using the device, the two ends of the connecting wire 15 are respectively installed on the controller 13 and the heating block 502. By pressing the button 14 fixedly installed on the controller 13, the temperature of the heating block 502 is adjusted to a suitable temperature, thus keeping the inside of the conveying pipe dry during the use of the device and making the conveying effect more stable.
