Drawings

Fig. 1 is a schematic view of the structure of a drying section of a paper machine with a simple and efficient paper fluff blowing device according to the present invention.

The specific implementation mode is as follows:

as shown in fig. 1, the present invention provides a paper machine drying section with a simple and efficient paper fluff blowing device. The drying part of the paper machine with the simple and efficient paper wool blowing device comprises a frame (not shown), a drying cylinder 10 and a paper wool absorbing device 20, wherein the drying cylinder 10 is arranged on the frame, and the paper wool absorbing device 20 is arranged on the outer side of the frame and extends to two ends of the drying cylinder 10.

The paper wool absorbing device 20 comprises a dust absorption pipe 21, an air blowing pipe 22, an air blowing device 23 and a dust collecting groove 24, wherein one end of the dust absorption pipe 21 extends to the outer side of the drying cylinder 10, the other end of the dust absorption pipe is connected into the dust collecting groove 24, and the air blowing pipe 22 is connected with the dust absorption pipe 21 and the air blowing device 23. Specifically, the dust suction pipe 21 includes a dust suction port (not shown) disposed at one side of the drying cylinder 10 and a dust outlet (not shown) disposed in the dust collection groove 24. The blowing pipe 22 is provided with a blowing opening at one side of the dust suction pipe 21, and the blowing opening is obliquely extended towards one side of the dust outlet, so that the air blown by the blowing pipe is discharged towards the dust outlet. The blowing device can blow air towards the blowing pipe 22 to form air flow in the dust suction pipe 21 at the front side of the blowing pipe 22.

In this embodiment, the dust suction pipe 22 includes a metal pipe 221 and a hose 222 installed on the metal pipe 221, the metal pipe 221 extends from the outside of the drying cylinder 10 to the inside of the machine frame, and the hose 222 is connected to the outside end of the metal pipe 221 and extends downward into the dust collecting groove 24. The metal pipe 221 is installed on the frame, and the design of the metal pipe 221 not only can play a supporting role, but also can adapt to the high-temperature and high-humidity environment in the equipment. The design of the hose 222 facilitates the placement of the dust collecting groove 24, cleaning of paper, and the like. An air inlet and an air outlet are arranged in the dust collecting groove 24, the bottom end of the hose 222 extends into the air inlet, the air outlet is provided with a detachable ground filter screen 25, and the air outlet and the air inlet are arranged on the top surface of the dust collecting box, so that paper wool can automatically fall into the dust collecting box under the action of gravity, and the filter screen can be prevented from being blocked by too much accumulated dust of the paper wool.

When the dryer is used, the blowing device is started to blow towards the dust absorption pipe 21 below the air blowing pipe 22, so that strong air flow is formed in the dust absorption pipe, paper wool on two sides of the drying cylinder can be absorbed into the dust collection box by utilizing the air flow principle, the paper wool is collected in the dust collection box after filtration, and air is discharged from the air outlet.

The above-mentioned embodiments only represent one embodiment of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
