Description

Technical Field

[0001] This utility model relates to the field of adjustable concentration pulping technology, and in particular to an adjustable concentration pulping machine for papermaking. Background Technology

[0002] Paper, made from plant fibers, is a sheet of paper that can be folded at will for writing. It is a medium for writing and printing, and can also be used for other purposes such as packaging and hygiene, such as printing paper, carbon paper, toilet paper, facial tissue, etc. The invention of paper with irregularly cross-arranged fibers originated in China. Existing pulp refiners typically consist of two opposing discs: a fixed disc and a rotating disc. The gap between the discs is adjustable to accommodate different grinding requirements. The equipment is equipped with feeding and discharging devices for conveying and discharging the pulp, and a pressurization system to control the grinding intensity. During operation, the pulp enters the gap between the two discs through the feed inlet. The rotating disc, driven by the drive system, rotates at high speed, working in conjunction with the fixed disc. Through shearing, squeezing, and friction, the fibers are separated, bristled, or cut. The processed pulp is discharged from the discharge outlet, significantly improving fiber fineness and uniformity, thus meeting the requirements of subsequent production processes. Existing pulp refiners have significant technical drawbacks. When the production line requires pulp of different concentrations, existing technologies often require disassembling the entire machine to replace the molds, resulting in long downtime of the production line and wasting time. To address this issue, a pulp refiner with adjustable concentration for papermaking is proposed. Utility Model Content

[0005] This utility model has the following beneficial effects: 1. In this utility model, the pulping mechanism of the equipment is driven by a motor to rotate the turntable. The turntable drives the pusher block to move axially in the pulping chamber. The pusher block and the clamping plate adopt an inclined surface fit structure, which converts the rotational motion of the turntable into the radial displacement of the clamping plate, thereby accurately adjusting the working gap between the pulping disc and the fixed block. The motor in the shredding assembly drives the rotating rod to rotate the shredding disc at high speed to perform preliminary crushing of the raw materials. The screen controls the particle size of the shredded material. The auger evenly transports the pre-treated material to the pulping chamber. The linkage design of pipe one and pipe two realizes the seamless connection of material between the pulping and grinding processes. This multi-mechanism collaborative working mode ensures the accurate control of pulp concentration.

[0006] 2. In this utility model, the motor of the filtration mechanism drives the cylindrical rotation, which in turn drives the connecting columns on both sides to move synchronously through the connecting sleeve. The cleaning plate at the end of the connecting column, buffered by springs and protective tubes, maintains appropriate contact pressure with the filter screen. The elastic design of the telescopic column automatically compensates for unevenness on the filter screen surface, preventing over-cleaning and damage. The support column adopts a double-column structure, providing stable support for the filter tank and ensuring stability during high-speed operation. The storage chamber and the filter tank are connected movably for easy maintenance and cleaning. This innovative self-cleaning filtration system effectively solves the problem of easy clogging of filters in traditional equipment, ensuring continuous production. Attached Figure Description

[0013] Working principle: Raw materials enter the tank 31 of the shredding assembly 3 through the feed inlet 38. Motor 2 32 drives the rotating rod 33 to rotate the shredding disc 34 at high speed. The specially designed blades on its surface powerfully crush the raw materials. The screen 35 is installed below the shredding disc 34 to separate the shredded material that meets the particle size requirements to the lower layer. The material that does not meet the requirements continues to be circulated for crushing. The auger 36 is driven by the motor to rotate at the bottom of the tank 31.

In this stage, the synergistic action of the shredding disc 34, screen 35 and auger 36 ensures that the raw materials achieve the ideal pretreatment effect. When different concentrations of pulp are required, the motor drives the turntable 23 to rotate, which causes the pusher block 24 to move backward, releasing the grinding disc 26. When a different model of grinding disc 26 is replaced, the pusher block 24 moves forward, causing the clamping plate 25 to clamp the mold, completing the replacement.

[0014] Pipeline 28 transports the ground slurry to filter tank 41. Motor 42 drives cylinder 43 to rotate, which in turn moves connecting sleeve 44 and connecting column 45, causing cleaning plate 49 to perform reciprocating cleaning motion along the surface of filter screen 410. The buffer system composed of spring 47 and protective tube 48 ensures that the cleaning force is moderate and avoids damage to the filter screen. Support column 411 provides stable support for the entire filtration mechanism 4. The processed slurry finally enters storage chamber 412 for temporary storage. The entire process, through the precise coordination of various mechanisms, realizes the fully automated production process from raw material processing to finished slurry.
