Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figures 1 to 4, a filter device for dust conveying pipeline, the filter device comprises a filter tube 2, both ends of the filter tube 2 are provided with flanges 3, and the filter tube 2 is connected to the conveying pipeline 1 through the flange 3 . The front end of the filter tube 2 is connected with a filter screen 11, the middle of the filter tube 2 is connected with a dust collection tube 4 extending vertically downward, the top of the dust collection tube 4 is open and communicated with the filter tube 2, and the bottom of the dust collection tube 4 closed. The bottom of the dust collecting pipe 4 forms a dust collecting chamber, and the dust collecting chamber is provided with a dust collecting groove 5, and the dust collecting groove 5 is connected with the dust collecting pipe 4 in a drawer type.

The top of the dust collecting pipe 4 is provided with a sealing plate 6, the end of the sealing plate 6 away from the filter screen 11 is hinged with the inner wall of the dust collecting pipe 4 through the rotating shaft. The rotating shaft is fixedly connected with the sealing plate 6, and the two ends of the rotating shaft respectively protrude out of the dust collecting pipe 4, and the two ends of the rotating shaft are respectively fixedly connected with a crank handle 7. When the crank handle 7 is turned to horizontal, the sealing plate 6 is also in a horizontal state. The top of the sealing plate 6 is also provided with a U-shaped limit stop 9, and the sealing plate 6 is in contact with the limit stop 9 when it is turned horizontal (as shown in FIG. 5).

The middle of the filter tube 2 is provided with a hook 8. When the crank handle 7 is turned to the horizontal, the hook 8 is hooked on the crank handle 7 to fix the crank handle 7. The upper part of the hook 8 is connected with a spring 10, which is convenient to elongate the hook 8.

The working principle of the present utility model is as follows:

When using, first turn the crank handle 7 to a horizontal state (as shown in Figure 3), and hang the hook 8 on the crank handle 7 to fix the position of the crank handle 7. At this time, the shaking handle 7 drives the sealing plate 6 to a horizontal state (as shown in Figure 1); the dust in the pipeline moves from the right side to the left side through the conveying pipeline 1, and the larger particles cannot pass through the filter screen 11. The trapped accumulation is above the sealing plate 6 . After a certain amount of debris is accumulated, remove the hook 8 and turn the crank handle 7 downward (as shown in Figure 4). At this time, the sealing plate 6 turns to the state shown in Figure 2, and the debris accumulated on the sealing plate 6 falls to the position of gravity. in the dust collection tank 5. Then turn the crank handle 7 to a horizontal state again, and hang the hook 8 on the crank handle 7 to fix the position of the crank handle 7 . After the debris in the dust collecting tank 5 has accumulated to a certain amount, the dust collecting tank 5 is taken out and the debris is cleaned.
