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 fiber oxidase composition for changing and improving fiber property, and a papermaking method and an application. The composition mainly comprises the following components: a bio-enzyme component with an oxidation function on fibers, and an auxiliary component for increasing catalytic activity on the fiber oxidase, wherein the bio-enzyme component is fiber oxidase for changing the surface property of the fiber by redox reaction; the auxiliary component is protein with catalytic action on the fiber oxidase; and the weight ratio of the bio-enzyme component to the auxiliary component is 1 to (0.4-50). When the composition is used for processing paper pulp, the strength of the prepared paper is significantly enhanced, and the drainage performance of the paper pulp is greatly 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.

The invention relates to a method for preparing paper pulp by using straws, which uses hydrogen peroxide to react violently with alkaline substances and release heat energy to prepare paper pulp. Crush wheat straw, rice straw, corn and other stalks, add caustic soda solution and stir to generate alkaline substances; then add hydrogen peroxide and stir to make hydrogen peroxide and alkaline substances decompose violently Fully decompose and separate the fiber and lignin, and then grind, beat and wash to remove the lignin, and then produce straw pulp for papermaking. The weight ratio of straw, caustic soda and hydrogen peroxide is: straw: caustic soda: hydrogen peroxide = 1: 0.03-0.12: 0.04-0.13; the reaction temperature is controlled at 70-100°C. If additives are added, the effect will be better. The whole process is simple, easy to operate, no black liquor and black water discharge, no pollution to the environment, the discharged water can be recycled after a little treatment, less water, electricity, coal, and energy are saved.

The present invention relates to the technical field of road construction, and specifically relates to a road surface compacting equipment for road construction, including a base frame, a connecting unit, a moving unit, a scraping unit, and a knocking unit. The right end of the base frame is provided with a connecting unit and a moving unit. Installed on the lower end of the base frame, the scraping unit is installed on the right side of the lower end of the base frame, and a knocking unit is arranged inside the base frame; the present invention can solve the following problems: 1. When the traditional foundation road surface is compacted, most of them are first passed through the existing Some scraping equipment scrapes it, and then uses the existing compaction equipment to compact it, thus adding unnecessary procedures and requiring workers to pick out the sundries on the road surface, thus affecting the working time; 2 .After the basic road is leveled, a vibratory compactor is generally used to tamp the basic road. The vibratory compactor usually performs single-point compaction on the basic road and requires a certain vibration time, so it cannot be processed continuously and affects the processing. Effect.
