Description

Technical Field

[0001] The present invention relates to the technical field of fiber product beating, in particular to a chemical mechanical pulp beating device and a beating method thereof. Background Art

[0002] Due to the lack of high-quality long-fiber raw materials, our raw materials are mainly domestic waste paper. However, after repeated recycling and reuse, the fiber quality of domestic waste paper has declined, and it is difficult to meet the production requirements of high-end kraft linerboard. Commercial chemical wood pulp and chemical bamboo pulp can meet the requirements of high-end kraft linerboard, but the price is too expensive. In order to expand the channel of high-quality raw materials, we began to use non-mainstream pulp types such as chemical mechanical bamboo pulp. However, chemical mechanical bamboo pulp has a high lignin content and poor fiber bonding strength. If it is not processed, it is difficult to meet the requirements of producing high-end paper.

[0003] However, the existing pulping equipment is unable to process impurities during use, so that the impurities will melt when encountering high temperatures during operation, and will not only adhere to the pulping rod of the pulping machine, but also affect the quality of the final pulping.

[0004] In order to solve the above-mentioned defects, in the prior art, Chinese patent publication number CN217579486U discloses an environmentally friendly fully automatic waste paper beating machine, which includes a support frame, a fixed box, a beating cylinder, a feed port, and a motor group. Support frames are provided at the four corners of the bottom of the fixed box, and the support frames are fixedly connected to the fixed box. A beating cylinder is provided inside the fixed box, and both ends of the beating cylinder are fixedly connected to the fixed box. A feed port is provided on the top of the beating cylinder, and the feed port is fixedly connected to the beating cylinder. A motor group is provided on one side of the fixed box, and the output shaft of the motor group passes through the fixed box and is fixedly connected to the beating cylinder. The motor drives the stirring blades on the two groups of stirring groups to stir and beat the waste paper, and then the grinding plates rotate together with the stirring blades to grind the waste paper. At the same time, the centrifugal force generated by the rotation of the stirring group can drive the waste paper to be crushed by the crushing group, which can make the waste paper more evenly crushed, and no waste paper with a larger specific gravity will entangle the stirring blades, making the beating faster, effectively improving the efficiency and speed of waste paper beating, and improving work efficiency.

[0005] In the prior art, a Chinese patent with publication number CN213447836U discloses a fiber beater, including a fiber beater, including a fixing device, a beating device, a filtering device, a control device and a collecting device. The fixing device includes a working box, a bearing and a limit block. The beating device includes a first rotating shaft, a second rotating shaft and a bushing. The upper surfaces of several bearings are provided with openings. One end of the first rotating shaft and the second rotating shaft rotates with the openings respectively. The control device includes a control panel, an electrical box and a motor. The collecting device includes a collecting pipe and a box cover. The collecting pipe is installed on one side surface of the working box, and the box cover is installed on the upper surface of the working box. The bearing is provided so that the rotating shaft is not easy to wear. The coarse crushing knife and the fine crushing knife are used to make the fiber beating more thorough. The bushing makes the rotating shaft rotate more efficiently. The establishment of multiple layers of filter plates makes the filtrate more pure.

[0006] During use, the above-mentioned device utilizes a filter plate to make the filtrate more refined, thereby preventing impurities from affecting the quality of pulping. However, in the above-mentioned device, during the process of the equipment beating the fibers, workers manually deliver the raw materials to the device. This feeding method cannot effectively control the average delivery volume of the raw materials, resulting in a low brooming efficiency of the bamboo pulp, thereby affecting the quality of the pulp.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The output shaft is driven to rotate by the stepper motor, and the output shaft drives the beating assembly to rotate. The beating assembly beats the fallen bamboo cellulose pulp, and hot water is added during beating to keep the temperature of the pulp at 50°C. The stepper motor is adjusted to 30,000 rpm for decomposition. The pulp is then discharged through the automatic unloading mechanism.

[0020] (2) The bamboo raw materials to be processed are fed in through the feed port, the servo motor drives the output shaft to drive the crushing roller 1 to rotate, and the belt drives the crushing roller 2 to rotate, the belt pulley increases the friction of the belt to reduce the probability of slipping, and the crushing roller 1 and the crushing roller 2 cooperate with each other to crush the fed bamboo raw materials, thereby achieving efficient processing of the bamboo raw materials;

[0021] (3) The crushed bamboo raw materials fall into the storage cavity inside the shell, and the stepper motor drives the beating assembly to rotate, thereby beating the fallen bamboo raw materials, and the beating assembly includes a linkage shaft connected to the output shaft, a beating roller for beating, and hot water is added during beating to keep the temperature of the pulp at 50°C. The pulped pulp is transferred to the grinding chamber through a conveying pipe, and the driving motor drives the grinding disc to rotate, and the grinding disc grinds the transferred pulp, thereby facilitating the pulp to be fully ground and mixed with the added softening enzyme and beating enzyme, ensuring better mixing effect with the recycled pulp;

[0022] (4) By starting the hydraulic pump, the hydraulic pump drives the telescopic rod to drive the mounting seat to move, the mounting seat drives the driving rod to drive the fixed seat to move, and the fixed seat moves the baffle horizontally along the inside of the base, so that the two sets of symmetrical baffles are opened, which facilitates the transmission of the pulp after beating;

[0023] (5) By starting the synchronous motor, the synchronous motor drives the spiral push rod to rotate, and the softening and beating compound enzyme JX-510 in the storage cylinder is transferred to the spiral push rod through the connecting pipe, thereby mixing with the pulp.
