The invention discloses a paper shredding device for a hydrapulper. The device comprises a cutter disc, wherein the external ring of the cutter disc is fixedly connected with three paper shredding cutters which are uniformly distributed along the circumferential direction; the inner and outer sides of the paper shredding cutters are arc; a sleeve cover is fixedly connected on the cutter disc; the central axes of the sleeve cover and the cutter disc are superposed; the external ring of the cutter disc is fixedly connected with three baffles which are uniformly distributed along the circumferential direction; parts, which are close to the sleeve cover, of the bottom end faces of the baffles are fixedly connected with the cutter disc, and the rest parts of the bottom end faces of the baffles are fixedly connected with the paper shredding cutters; and the heights of the ends, which are fixed with the sleeve cover, of the baffles are more than the heights of the other ends of the baffles. The paper shredding device for the hydrapulper has the advantages that under the condition of not changing the original power, the linear velocity is accelerated by 5-6m / second, and raw materials can be dragged towards the paper shredding cutters under a powerful vortex generated in the operation process and quickly shredded by the paper shredding cutters, so that the pulping velocity is accelerated, and the beating degree is improved.

The invention discloses a pulp refiner, which comprises a grinding disc part, a transmission part and a motor which are connected in sequence, the grinding disc part is installed in a casing, and both the casing and the transmission part are installed on a frame; the grinding disc part includes a rotating grinding disc and a The fixed grinding disc matched with the rotating grinding disc is installed on the main transmission shaft of the transmission part, and the fixed grinding disc is installed on the inner wall of the casing. The transmission part mainly includes the main shaft, bearing seat, driving coupling and driven coupling. The tooth surfaces of the rotating grinding disc and the fixed grinding disc are provided with concentric circular retaining dams. There is a section between every two concentric circular retaining dams. Each grinding disc is provided with 3 or more concentric circular intervals. The tooth depth of the grinding teeth also gradually decreases with the increase of the radius; the working surface of the first circle of grinding gears on the rotating grinding disc near the center of the circle forms an acute inclined angle with the plane of the grinding disc. The invention can overcome the disadvantages of the prior art, and can achieve the effect of high efficiency and low consumption.

The invention discloses a glass fiber blanket and a producing method thereof. The method comprises the steps of mixing the following components , by mass, 35-40 parts of silica flour, 5-12 parts of feldspar, 9-14 parts of borax, 1-3.5 parts of calcite, 6-8 parts of dolomite, 11-14 parts of soda ash, and 15-25 parts of sheet glass to form a mixture; melting the mixture to obtain glass metal; placing the glass metal in a centrifugal machine for spinning treatment to obtain glass fiber and spraying water and binders onto the surface of the glass fiber in a vaporific mode at the same time; placing the glass fiber coated with the binders in a cotton collecting machine to enable the glass fiber to evenly fall onto the cotton collecting machine under the action of a negative-pressure fan to form a glass cotton layer; and conveying the glass cotton layer well laid to a curing oven through a conveyer to be cured to obtain the glass fiber blanket.
