[0006] This utility model discloses a pulp anti-clogging conveying device, comprising a conveying box and a one-way discharge valve, the one-way discharge valve being connected to the outer wall of the conveying box; it also includes a power unit, a conveying device, a crushing device, a conveying pipe, a one-way inlet valve, and a piston. A vent is provided at the top of the conveying box, the conveying pipe is connected to the outer wall of the conveying box, the one-way inlet valve is connected to the inlet end of the conveying pipe, the piston is slidably mounted inside the conveying box, a power unit is provided on the conveying box for driving the piston to move up and down, a crushing device is provided inside the conveying box for crushing the pulp, and the conveying device is located inside the conveying pipe for conveying the pulp. The pulp is conveyed into the conveying pipe through a one-way inlet valve, and then into the conveying box through the conveying pipe. The pulp in the conveying box is then discharged through a one-way outlet valve. A piston is driven by a power unit to move up and down. When the piston moves upward, it sucks the lower part of the conveying box, thus causing the one-way inlet valve to draw the pulp into the conveying box. When the piston moves downward, it squeezes the pulp in the conveying box out through the one-way outlet valve, improving the pressure conveying effect of the pulp and reducing the blockage of the device. At the same time, it works with the crushing device to crush the pulp in the conveying box, and works with the conveying device in the conveying pipe to convey the pulp, further improving the smoothness of the pulp conveying.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the pulp is conveyed to the inside of the conveying pipe through the one-way inlet valve, and then conveyed to the conveying box through the conveying pipe. After that, the pulp in the conveying box is discharged through the one-way outlet valve. The piston is driven to move up and down by the power device. When the piston moves upward, it sucks the lower part of the conveying box, so that the one-way inlet valve sucks the pulp into the conveying box. When the piston moves downward, it squeezes the pulp in the conveying box out through the one-way outlet valve, which improves the pressure conveying effect of the pulp and reduces the blockage of the device by the pulp. At the same time, it works with the crushing device to crush the pulp in the conveying box and works with the conveying device in the conveying pipe to convey the pulp, further improving the smoothness of pulp conveying.
