Abstract
The invention discloses a physical method for cleaning an inner cavity of a power coating extruder. The cleaning process is performed after the production is ended. 1-2 kg of granular grains or a rag cloth which has a thickness less than 0.8mm and a total width of 0.5-1.0m2 are/is used as a cleaning material. The physical method comprises the following steps: after the extruder is emptied and is at an idle state, adding the prepared cleaning material from a feeding port; after discharging the material from a discharge port in sequence, blowing compressed air towards the feeding port for 1-5 minutes; at a stopped state, cleaning the inner cavity by filling water from the feeding port of the extruder till clean water flows from the discharge port of the extruder; and finally, blowing the compressed air towards the feeding port for 1-5 minutes. By performing the cleaning steps of the physical method, the power coating maintained in the inner cavity of the extruder can be completely removed. The inner cavity is cleaned by using the physical method provided by the invention, so that the inner cavity is free from the cross-linking solidifying reaction and the inner cavity does not need to be heated when the extruder is reused. The physical method has the advantages that the cleaning cost is low, the cleaning degree is high, the efficiency is high, and the energy and the working hours are saved.
Description
Technical field
The present invention relates to a kind of cleaning method of removing product residue thing in the extrusion equipment, particularly a kind of inner chamber that adopts Physical to clean powder coating extruder.
Background technology
Powdery paints has another name called molding powder, and it is a kind of novel surface anti-corrosion material, and this material can be mixed with different colors as required.Extruder is the key equipment that powdery paints is produced, will be by forming preparation and mixing and stirring into the paste compound with selected color and insert extruder in the production, and the compound of extruding is ground into powder in subsequent handling.Conventional extruder is screw, and extruder uses still residual a certain amount of compound of rear its inner chamber.Because containing cure component in the compound, if just cross-linking and curing reaction occurs in untimely removing, with the extruder inner chamber and screw rod is cementing can not normally use together.For fear of the problems referred to above occurring, the production scene is usually adopted and is immediately poured into low viscosity resin in extruder, utilize its repeatedly pre-arcing characterisitics carry out necessary cleaning.This technology is simple, can effectively clean.But prior art must consume resin, because the resin price height must cause the cleaning cost large.And before next time start residual resin also will clean by heat fused the time, otherwise extruder can not run well.In addition, because of reasons such as prior art cleaning cost are large, and scavenging period is long, easily cause cleaning thorough not, when particularly product is changed color, if the extruder inner cavity cleaning is unclean, must cause the product colour contamination to bring certain economic loss.
Summary of the invention
The present invention proposes a kind of Rapid Cleaning mainly for the deficiencies in the prior art, and it is low to clean cost, and cleanliness factor is high after cleaning, and non-environmental-pollution, the physical method of the cleaning powder coating extruder inner chamber that need not heat when again starting shooting.
The present invention is achieved through the following technical solutions technical goal.
Clean the physical method of powder coating extruder inner chamber, clean producing and immediately carry out after finishing, its improvements are: cleaning with material is that granularity 1～5mm and gross weight are that the grain of 1～2kg or thickness are less than 0.8mm and total breadth 0.5m
2～1.0m
2The cloth waste material, the concrete cleaning follows these steps to carry out:
(1) extruder is in the idle running situation after emptying;
(2) add standby cleaning of institute from the charging aperture of extruder and use a material, to be cleanedly discharge from the discharging opening order with material;
(3) compressed air with 1～5Mpa blew 1～5 minute facing to the extruder charging aperture;
(4) shut down;
(5) from the cleaning of pouring water of extruder charging aperture, waterflood injection rate is controlled at water and does not flow out from extruder institute gas-distributing motor end and be limited, and is washed to the extruder discharging mouth and flows out till the clear water;
(6) again blew 1～5 minute facing to charging aperture with the compressed air of 1～5Mpa.Clean and use
Material is grain, and its kind is wheat or barley, also can be corn.
The present invention compared with prior art has following good effect:
1, used cleaning material is easy to get, and consumption is few, the cleaning cost is low;
2, granular material rotates at random, mechanically washes away each position of extruder inner chamber, and cleaning quality is good, efficient is high;
3, used cleaning material is natural wheat, barley, corn or artificial woven cloth, paper, cleans the sorrow of non-environmental-pollution;
4, the extruder after the cleaning reuses the Shi Buxu heating, and both energy savings was also saved man-hour.
The specific embodiment
The invention will be further described below in conjunction with embodiment.
Embodiment 1
The physical method that cleans the powder coating extruder inner chamber is immediately to carry out after each production or the end of crowded sample, the extruder model that present embodiment cleans is 60E, because of its cavity volume less, the wheat of selecting market easily to purchase is used material as cleaning, wheat is dry shape, get gross weight 1.2kg wheat, the concrete cleaning follows these steps to carry out:
1, extruder is in the idle running situation after emptying;
2, the charging aperture from extruder adds standby wheat, and along with the bolt rotary of extruder, wheat is discharged from the discharging opening order;
3, the compressed air with 1Mpa blew 2 minutes facing to the extruder discharging mouth;
4, shut down;
5, from the cleaning of pouring water of extruder charging aperture, waterflood injection rate is controlled at water and does not flow out from extruder institute gas-distributing motor end and be limited, and is washed to the extruder discharging mouth and flows out till the clear water;
6, again blew 3 minutes facing to charging aperture with 1Mpa compressed air.
Clean through above-mentioned steps, the residual powdery paints of extruder inner chamber all is eliminated.Clean because the present invention is Physical, the extruder inner chamber does not have the cross-linking and curing reaction condition after cleaning, so reuse the Shi Buxu heating.It is low that the present invention cleans cost, and cleannes are good, and efficient is high, and has both saved the energy and also saved man-hour.
Embodiment 2
Present embodiment is identical with embodiment 1 cleaning machine model, and the cleaning material of only selecting is barley, and its cleaning step is identical with embodiment 1 with effect.
Embodiment 3
The extruder model that present embodiment cleans is APV70, and its cavity volume is larger, and the cleaning material of selecting is granular corn, and corn is dry shape, gets its 2kg, and concrete cleaning step is identical with embodiment 1, and its cleaning performance is similar.
Embodiment 4
