Description
Technical field
The utility model provides a kind of device that is used for the remaining coating cleaning of thermodyn process heavy caliber ductile iron pipe pipe die inwall--dull and stereotyped cleaning brush of lift of efficient, environmental protection.
Background technology
There are three kinds on the inner wall cleaning technology tradition of thermodyn process heavy caliber ductile iron pipe:
1) folding wheeled cleaning brush.
The structure of this cleaning brush is seen Fig. 1.It comprises steel wire 01, and on the skeleton 02 in the middle of being fixed on, the skeleton 02 of cleaning brush by the centre is fixed on (see figure 2) on the folding stand 03 of front end of casting car 04, before the work protective cover on the brush body taken off, and manually folding stand 03 opened.Casting car 04 moves reciprocatingly during work, pipe die A low speed rotation, and the outer surface of cleaning brush steel wire 01 contacts with pipe die A inwall retention wire, and steel wire 01 is cleaned the remaining coating of pipe die A inwall totally with water.Work finishes manually cleaning brush to be folded and restores, and protective cover is playbacked.Whole process is lasted 12～17 minutes under the normal condition.Course of work signal is seen shown in Figure 2.There is following drawback in this working method: 1, brush body serious wear.Because this device is worked under hot environment for a long time, hardening after wire brush is heated.Add and be subjected to forceful action, bristle very easily lodges.Cause the brush body needs often to be changed.2, guarantee very difficulty of line contact.The influence of cantilever thermal deformation of car folding stand 03 of being cast, and be subjected to the cleaning plant influence of mounting accuracy, this cleaning plant often can not guarantee the line contact.Cause cleaning effect poor, need to prolong clearance time to guarantee cleaning effect.Because clearance time is long, cleaning effect is not good, and comprehensive cost is too high.
2) removable wheeled pipe die cleaning brush.
This cleaning plant when work hang with electric hoist casting car 04 cantilever front end above, adopt the fast-assembling mode to fix, work finishes and hangs assigned address after the dismounting.About the position relative fixed of 2 groups of cleaning brush 05, make different cleaning brush groups respectively at the pipe die of different size.The work schematic diagram is seen Fig. 3.Relative first kind of this cleaning plant, it is good to have a cleaning effect, clears up advantage rapidly.But also have following drawback: 1, brush wearing and tearing back cleaning effect weakens, and the later stage clearance time is long, clears up unclean.2, the be heated influence of back deformation of car cantilever of being cast often causes the stressed excessive damage of an end brush, the contact of other end discord pipe die inwall.Cleaning plant lost efficacy.
3) pipe die inner wall cleaning mode changes the residual core cleaning of artificial throwing into.
Pipe die inner wall cleaning mode changes the labor cleaning into.Fig. 4 is seen in the work signal.The concrete operations mode is: the bell of pipe core of remaining one-tenth piece kept after cast molding was finished, and manually with spade remaining bellmouth core was thrown away tube wall behind the pipe die tube drawing, the rotation of pipe die middling speed.Centrifugal force makes the residual core 06 of bellmouth be adjacent to pipe die A inwall, utilizes friction that the remaining coating of pipe die inwall is come off.Centrifugal rotation finishes the back and adopts pneumatics wind that the powder-type coating ash of pipe die inwall is blown away.Residues such as the block residual core that the pneumatics wind is not walked, sand grains, the hand-held big besom of operator gets into pipe die inside it is scanned out.Utilizing pneumatics wind will clean the residual trickle residues such as dust in back once more blows out.Whole scale removal process finishes.Key points for operation are the selection of pipe die rotating speed.Can not be too high, make residual core under the effect of centrifuge with pipe die rotation, do not reach the purpose of cleaning, again can not rotating speed low excessively, cleaning efficiency be too low, influences productive temp.The advantage of this manner of cleaning up is: 1, cleaning efficiency height.Whole scale removal process only needs about 8 minutes.2, cleaning effect is good.If rotational time and pipe die rotating speed are selected correct, just the dope layer full scale clearance of remnants can be exposed the body of pipe die inwall in the short period of time.3, comprehensive cost is extremely low.This manner of cleaning up is substantially without special equipment, and required residual core belongs to twice laid, only needs a spot of big besom and pneumatics wind just can satisfy instructions for use.When possessing above-mentioned advantage, its drawback is also apparent: 1, labor strength is big.No matter be to throw away residual core inward or clean residual core outward, still the cleaning of twice pair of pipe die inwall all needs to adopt the pure handwork of manpower.2, work under bad environment.It at first is high-temperature operation.Thermodyn process technology, as its name suggests, the pipe die inwall will keep higher temperature all the time.Under normal circumstances, the serviceability temperature of pipe die is 180～250 ℃.The workman need get out in inner frequent the creeping into of the pipe die of high temperature when operation, very easily causes the workman to suffer heatstroke.Next is the dust work of high concentration.The discarded coating ash of clearing up piles up that density is little, light specific gravity, quantity are many, flies upward all over the sky under the purging of pneumatics wind.The workman works long hours in this working environment, and the infringement of health is well imagined.3, working stamndard disunity.The coating of pipe die inwall is if thoroughly remove, and the time that then needs is longer, average out to 20 minutes.For keeping higher rhythm of production, the operator often reduces quality standard, causes the coating cleaning of pipe die inwall unclean.The coating of inwall remnants directly has a negative impact to the outward appearance of pipe, and when situation was the most serious, part pipe even the same outward appearance of map occurs had a strong impact on the product external image.4, can not adapt to high-intensity production needs.Pipe of this every production needs at least 15 minutes time that the production technology of pipe die inner wall cleaning is become impassable obstacle, and the lifting of output has been constituted restriction.
