Among them, the upper end side wall and the lower end side wall of the pulping barrel 1 are respectively provided with a slag outlet and a pulp outlet.

[0024] like Figure 2 As shown, the refining mechanism of the refiner includes a feed pipe 3, a filter screen 4 and a motor connecting plate 5 which are sequentially arranged in the refining barrel 1 from top to bottom, and the feed pipe 3, the filter screen 4, the motor connecting plate 5 and the refining barrel 1 are coaxially arranged.

[0025] The filter screen 4 is fixed on the motor connection plate 5, and a lower grinding disc 6 and an annular upper grinding disc 7 are arranged horizontally in the filter screen 4, and the lower grinding disc 6 and the upper grinding disc 7 are arranged side by side. The lower end of the feed pipe 3 is fixedly connected to the upper grinding disc 7, and the inner cavities of the two are connected. The upper end of the feed pipe 3 extends out of the refining barrel 1 and is fixedly connected to the above-mentioned hopper 2, and at this time, the inner cavities of the feed pipe 3 and the hopper 2 are connected. The upper end of the motor connection plate 5 extends into the filter screen 4 and is fixedly connected to the lower grinding disc 6. Figure 1 As shown, a straight rod-shaped stirring rod 8 is vertically disposed in the feed pipe 3, and the axes of the stirring rod 8 and the feed pipe 3 are arranged parallel to each other; the lower end of the stirring rod 8 extends into the upper grinding disc 7 and is fixedly connected to the lower grinding disc 6. Preferably, the stirring rod 8 and the feed pipe 3 are arranged coaxially.

[0026] In actual products, the refiner also includes a motor 9 vertically arranged below the refiner barrel 1. The main shaft of the motor 9 extends into the refiner barrel 1 and is connected to the motor connecting plate 5 to drive the lower grinding plate 6 and the stirring rod 8 to operate synchronously.

[0027] By vertically arranging a high-speed rotating stirring rod 8 in the feed pipe 3, the materials in the feed pipe 3 are dispersed to avoid blockage in the feed pipe 3, thereby greatly enhancing the operating stability of the refiner.

[0028] In this embodiment,

[0029] The connection mode of the feed pipe 3 and the upper grinding disc 7 is as follows: the lower end of the feed pipe 3 is flared, and the lower end of the feed pipe 3 is sleeved and fixed on the upper grinding disc 7. In the actual product, the feed pipe 3 is fixedly connected to the upper grinding disc 7 by a circle of screws.

[0030] The connection method of the lower grinding disc 6 and the motor connecting disc 5 is as follows: the lower grinding disc 6 has a central through hole coaxially arranged thereon, the upper end of the motor connecting disc 5 is a shaft body 5a matching the central through hole, and the shaft body 5a is inserted and fixed in the central through hole. The above design facilitates the connection of the motor connecting disc 5 and the lower grinding disc 6.
