Kitech Machinery Announces Successful Testing of Auto Self-Cleaning Laser Filter System Featuring Melt Pum

I. Efficiently deal with complex impurities, suitable for a wide range of plastic types

This week, Kitech Machinery successfully tested the automatic laser filter system with integrated melt pump. The system is designed for efficient filtration of various stubborn impurities in plastic recycling materials (such as PP, PE, LDPE, HDPE, PS, EPS, ABS, PVB, PVC, etc.). It can effectively filter a variety of pollutants including iron, steel, wood chips, paper, textile fibers, unmelted plastics, aluminum, sand, copper, stones, etc., and significantly improve the quality of recycled pellets.

II. Core advantages of laser filtration:

Reduced labor costs:

Farewell to the frequent shutdown of traditional manual screen changers for screen changing! The self-cleaning laser filter automatically removes filter impurities, significantly reduces labor costs, ensures continuous production, and greatly improves overall efficiency.

Ultra-long service life:

The core component-the laser screen plate is made of high-strength chromium-molybdenum steel and has excellent wear resistance and toughness. Its 1.5 mm thickened design ensures an ultra-long service life and significantly reduces the frequency and cost of filter replacement.

Excellent filtration accuracy:

Thousands of precision laser drilled holes are distributed on the laser screen to achieve efficient impurity interception. Thanks to advanced laser technology, the filtration accuracy can reach 80 to 800 microns.

High-frequency self-cleaning function:

The system is equipped with six high-efficiency scrapers to form a continuous cleaning mechanism that can quickly scrape impurities on the surface of the filter. This high-frequency cleaning ensures that the filter holes are quickly restored and unobstructed, and high production can be maintained even in the granulation process of highly polluted raw materials.

Stable constant pressure intelligent operation:

The speed of the scraper and the discharge screw is automatically adjusted in real time according to the melt pressure to ensure that the entire filtration process operates at a constant pressure. This "constant pressure operation" mode enables the system to stably and efficiently handle highly polluted materials.

Extremely low melt loss:

When impurities are discharged, only a very small amount of melt is taken away, and the melt loss rate can be controlled at an extremely low level of 1%-3%. Compared with traditional filters, it greatly reduces raw material waste and improves production efficiency.

III. Melt Pump: The Power Core of Stable Output

Core Function: Melt Pump (Melt Pump), its main function is to pressurize and stabilize the high-temperature plastic melt from the extruder, and deliver the melt with stable flow to the extruder head at constant pressure and uniform speed.

Working Principle: The core is a pair of precision meshing gears made of high-strength alloy steel or special materials. The motor drives the active gear to rotate, driving the driven gear, and the melt is sucked into the gear gap from the inlet and forced to be pushed to the outlet. This process achieves stable delivery and pressure increase of the melt.

Application Range: Widely used in the field of plastic extrusion molding, including granulation, film, pipe, plate, sheet, etc.

Core Advantages of Melt Pump

Significantly increase output (about 20%):

The melt pump is superior to various extruders in stabilizing melt pressure and flow. Using it in series with a single-screw or co-rotating twin-screw extruder can significantly increase the output of the entire production line by about 20%.

Effective energy saving (about 25%):

Configuring a melt pump on a single/twin screw extruder can significantly improve the performance of the main machine and achieve higher quality and output. The energy consumption per kilogram of material processed can be reduced by about 25%.

Precise process control:

Key parameters such as melt flow, pressure and temperature can be accurately controlled to meet the strict requirements of different production processes for melt delivery.

IV. Maintenance and care:

• Regular cleaning: Regularly clean the internal pipes and devices of the melt pump to prevent molten material residue from causing blockage or poor operation.
• Lubrication maintenance: Regularly lubricate and maintain the mechanical parts of the melt pump to ensure smooth operation of the equipment and extend its service life.
• Seal inspection: Regularly check the status of the melt pump seal to ensure good sealing performance, prevent leakage, and ensure equipment safety and personnel safety.
