A three-roll inner cavity dirt cleaning system and treatment method

Abstract

The invention relates to a cleaning system and a processing method for a three-roller inner cavity. The cleaning system comprises a purification pool, a water supply pipeline, a booster pump, flow valves, scale cleaning steel balls, three rollers, temperature gauges, a return water pipeline, a stainless steel filter screen, a cooling tower, a precipitation tank and a water supplement pipeline in an assembling mode. The processing method using the system is combined with the processing system, according to the processing system, cooling can be performed, scale can be cleaned, so that the temperature of the three rollers is stable, the three rollers automatically clean the scale without machine halt and working stopping, time and labor are saved, meanwhile, using of chemical reagents and sewage discharge are avoided, and in addition the devices are effectively protected from being corroded by the chemical reagents and damaged.

Description

Technical field [0001] The invention relates to a three-roller inner cavity dirt cleaning system and a processing method. Background technique [0002] The sheet machine is mainly composed of material tube heating and screw extrusion device, extrusion die device, three-roll rolling cooling setting device, edge trimming and traction winding device. When the PP material is uniformly and continuously fed into the sheet machine, under the constant temperature of the material pipe (220℃±10), the extrusion screw extrudes the completely dissolved PP material to the die, and the extruded paste PP material passes through three rollers Rolling and cooling (60℃±10) at the same time to form a certain thickness of the sheet, and then according to the wide size of the cutting edge synchronously. [0003] The three rollers of the sheet machine are the key control points for sheet forming, and temperature changes directly affect the quality of the sheet. Due to the continuous work of the three r...

Problems solved by technology

[0004] At present, the principle of water-cooling exchange is generally used in the market to solve the temperature rise of the three rollers, but there is dirt in the water. With the increase of scale in the inner cavity of the three rollers, the cooling effect is difficult to meet the design requirements. To solve this problem, first The consideration is to clean the scale on the inner walls of the three rollers. However, the inner chambers of the three rollers only have a central external pipe connection with a diameter of 50mm on both ends, which cannot be seen or touched by the eyes, and the scale cannot be removed directly with an appliance. Usually, regular use of chemical Cleaning solution is used to clean, but the effect is not ideal; one has to shut down and stop cleaning, wasting production time, manpower and material resources

Second, flushing causes a large amount of sewage to pollute the environment

3 Due to the corrosion of chemical reagents, the equipment and pipelines are corroded and damaged
