Description

Technical Field

[0001] This invention relates to the technical field of waste gum collection in the production of cellulose fibers using a novel solvent method, specifically a method for the rapid cooling and pulverization of high-temperature, high-viscosity waste gum. Background Technology

[0002] Aqueous solutions of N-methylmorpholine oxide (NMMO) are a high-quality solvent in the manufacturing process of green fibers. In the new solvent-based cellulose dope production process, to achieve circular and green production and reduce production costs, the NMMO solvent is diluted from a higher concentration to a lower concentration during fiber production. Therefore, a large amount of NMMO remains in the low-concentration solvent, making it valuable for recovery, concentration, and recycling. Thus, solvent recovery is a crucial step in the production of cellulose fibers using the new solvent method. In actual production, when the state or properties of the material do not meet the requirements for spinning quality, waste glue is generated. Generally, a waste glue discharge device is installed at the beginning of the conveying system to promptly discharge the waste glue, cool it, and collect it, laying a good foundation for improving solvent recovery and utilization efficiency in the future.

[0003] However, existing waste adhesive discharge devices typically cool the discharged liquid by first air and then by cold water. The new solvent-based cellulose liquor, on the other hand, is a heat-sensitive, high-temperature, and high-viscosity material. Short-term natural cooling followed by water cooling is far from sufficient to collect the waste adhesive and recover the solvent quickly. Furthermore, cold water cannot effectively cool the internal components of the high-temperature, high-viscosity fluid in a short time, leading to a large accumulation of waste adhesive that becomes increasingly time-consuming, labor-intensive, and costly to collect manually later. Summary of the Invention

[0004] This invention addresses the aforementioned shortcomings by proposing a method for the rapid cooling and pulverization of high-temperature, high-viscosity waste adhesive. The method significantly accelerates the cooling rate of high-temperature, high-viscosity waste adhesive, and when combined with waste adhesive cutting and pulverization, it greatly improves the recycling efficiency of high-temperature, high-viscosity waste adhesive, laying the foundation for improved subsequent solvent recovery efficiency. This solves the technical problem that traditional processes cannot collect waste adhesive and recover solvents from high-temperature, high-viscosity materials in a short time.

[0005] The objective of this invention can be achieved through the following technical solutions: The steps of a method for rapid cooling and pulverizing high-temperature, high-viscosity waste adhesive according to the present invention are as follows: A. Waste adhesive discharge: High-temperature, high-viscosity fluid waste adhesive flows out evenly in a linear fashion along the bottom of the discharge pipe, through a row of discharge holes evenly distributed along the length. B. Waste adhesive cooling: The linear fluid waste adhesive flowing out in step A falls downwards and vertically penetrates the inner cavity of the cooling box arranged directly below the discharge pipe. During this penetration process, the linear fluid waste adhesive is sprayed and cooled from the outside to the inside by cooling water sprayed by several sets of spray components located on the front and back sides of the inner cavity of the cooling box in an alternating manner. After being rapidly cooled, the linear fluid waste adhesive becomes linear solid waste adhesive and falls onto the inclined slide plate of the chute connected to the outlet end of the cooling box after passing through the inner cavity of the cooling box. C. Waste Glue Segmentation: The linear solid waste glue that fell onto the inclined slide in step B is swept down the inclined slide by the cooling water. It passes through a cutting mechanism arranged in the inner cavity of the chute, which rotates and is tangent to the inclined slide during rotation. When the fan-shaped protruding cutter rotates to the position tangent to the inclined slide, it cuts the linear solid waste glue at this point. The process is repeated until the linear solid waste glue is cut into waste glue segments of uniform length. D. Waste Glue Crushing: After the waste glue segments obtained in step C slide out of the inclined slide, they fall parabolically into the inlet chamber of the crushing mechanism connected to the outlet end of the chute under the action of inertia and gravity. They gradually gather in the triangular area formed by two crushing rollers that are symmetrically arranged in front and behind below the inlet chamber and rotate at high speed in opposite directions. Then, the waste glue segments in the triangular area are squeezed and crushed into waste glue particles of uniform size as the two crushing rollers rotate in opposite directions. The resulting waste glue particles are output from the outlet end of the crushing chamber and then transferred to the next solvent recovery station.

[0006] The discharge pipe described in this invention is a jacketed heating structure formed by nesting an inner pipe and an outer pipe, and the left and right ends of the discharge pipe are closed ends; the diameter of the discharge hole is 15-20mm, and the number of discharge holes is 40-90.

[0007] The number of spray components described in this invention is 6 to 10 sets; each set of spray components consists of a longitudinal cooling water main pipe connected to the cooling water source, a horizontal branch pipe vertically connected to the longitudinal cooling water main pipe in parallel, and a fan-shaped nozzle installed at the end of the horizontal branch pipe; in each set of spray components, the number of fan-shaped nozzles is equal to the number of discharge holes.

[0008] The temperature range of the cooling water described in this invention is 27–32°C.

[0009] In this invention, the length of the waste glue segment is equal to the circumference of the tip of the fan-shaped protruding cutter.

[0010] In this invention, the open end of the chute directly opposite the inclined slide is covered with a glass sealing plate.

[0011] The angle between the inclined slide and the horizontal plane in this invention is in the range of 45 to 60 degrees.

[0012] In this invention, the distance between the roller surfaces at the closest position of the two crushing rollers is less than the diameter of the discharge hole at the bottom of the discharge pipe.

[0013] The rotational speed of the crushing rollers described in this invention is ≥1050 rpm.

[0014] In this invention, scrapers are fixed on the bottom inner walls of both sides of the crushing chamber; the distance between the scraping end of the scraper and the roller surface of the crushing roller is less than the minimum cross-sectional size of the waste rubber particles.

[0015] The design principle of this invention is as follows: First, this invention features a jacketed heating structure and a discharge pipe with a row of discharge holes along its length at the bottom. This design keeps the waste adhesive in a molten state, facilitating rapid discharge, and allows the molten waste adhesive to flow out of the discharge holes in a linear fashion, forming a downward-falling linear fluid waste adhesive. Next, as the linear fluid waste adhesive vertically penetrates the cooling chamber, cooling water sprayed from fan-shaped nozzles in several sets of staggered spray assemblies on both sides cools it circumferentially from the outside in. This rapidly cools the linear fluid waste adhesive into a linear solid waste adhesive, significantly accelerating the cooling speed of high-temperature, high-viscosity waste adhesive and solving the technical problem of traditional processes being unable to cool the interior of high-temperature, high-viscosity fluids in a short time. Then, the linear solid waste adhesive slides down the inclined slide under the flushing action of cooling water, passing through a cutting mechanism arranged inside the chute cavity. During rotation, a fan-shaped protruding cutter is tangential to the inclined slide. When the fan-shaped protruding cutter rotates to the position tangential to the inclined slide, it cuts the linear solid waste adhesive at this point, cutting the sliding linear solid waste adhesive into waste adhesive segments of uniform length, preparing for waste adhesive crushing. Subsequently, after sliding out of the inclined slide, the waste adhesive segments fall parabolically under the action of inertia and gravity into the crushing mechanism, where they are crushed into uniformly sized waste adhesive particles by two high-speed, oppositely rotating crushing rollers. The resulting waste adhesive particles are then transferred to the next solvent recovery station, preparing for solvent recovery. In summary, the method of this invention can greatly accelerate the cooling rate of high-temperature, high-viscosity waste adhesive, and, combined with waste adhesive cutting and crushing, can significantly improve the recovery efficiency of high-temperature, high-viscosity waste adhesive, laying the foundation for improving subsequent solvent recovery efficiency. This solves the technical problem that traditional processes cannot collect waste adhesive and recover solvents from high-temperature, high-viscosity materials in a short time.

[0016] The beneficial technical effects of the present invention are as follows: The method of this invention can greatly accelerate the cooling rate of high-temperature, high-viscosity waste adhesive, and when combined with waste adhesive cutting and crushing, it can greatly improve the recycling efficiency of high-temperature, high-viscosity waste adhesive, laying the foundation for improving the subsequent solvent recovery efficiency. It solves the technical problem that traditional processes cannot collect waste adhesive and recover solvents from high-temperature, high-viscosity materials in a short time.
