The specific embodiment
As shown in Figure 1; The casing 6 of decontamination box of long workpieces of the present invention is divided into three independently operation intervals by two dismountable dividing plates 9; The a pair of heating tube 1 that coils into s shape is all arranged at the bottom of each operation interval; On heating tube, be provided with a work rest 4, between work rest 4 and the heating tube 1 certain distance arranged, six and seven ultrasonic vibration boxes 8 are set respectively in casing 6 both sides; Each operation interval all has one independently to open an air vent 7 on case lid 5, the case lid 5; Arranged outside at casing 6 has ventilation interlock 12, and it is connected with switch cover device 10 through connecting rod 11, and casing 6 outsides of each operation interval also are provided with feed tube 2, intake valve 3 simultaneously.
As shown in Figures 2 and 3; Dividing plate 9 outsides are screwed an air seal circle 16; Air seal circle 16 is taken over 17 through gas and is linked to each other with the intake valve 3 that is arranged on casing 6 outsides, and two guide grooves 15 are arranged in the inboard of decontamination tank, fixes dividing plate 9 gentle body sealing rings 16.The pressing plate 13 that dividing plate 9 quilts are connected with axle 18 compresses, and the pressing plate baffle plate 19 of pressing plate 13 just is stuck in to be arranged at fixes pressing plate 13 below the inboard locating piece 14 of casing 6.
When practical operation, with pressing plate 13 translations one segment distance, pressing plate block 19 and casing 6 inboard locating pieces 14 are staggered along axle 18; Pressing plate 13 is with axle 18 rotations, and pressing plate 13 is opened, and the dividing plate 9 that will have air seal circle 16 inserts in the guide groove 15; Connect gas and take over 17; Pressing plate 13 is rotated to level, move to locating piece 14 positions, pressing plate 13 is able to fix.Open intake valve 3, sealing ring 16 is inflated, and has so just realized the physical isolation of decontamination box of long workpieces casing 6, and the program of removing dividing plate realizes according to reverse procedure.
As shown in Figure 4; Case lid 5 links to each other with crank mechanism 20 through bolt, and crank mechanism 20 serves as that axle links to each other with the airduct bearing 33 that is fixed on casing 6 outsides with connecting rod 11, and the other end of crank mechanism 20 links to each other with screw thread Y-piece 21; Screw thread Y-piece 21 be connected piston pulling 22 and connect; Pull bar 22 passes a spring 23, and spring 23 is fixed on the cylinder base 24, and the upper and lower of cylinder 25 respectively connects a Compressed Gas and takes over 26.
When practical operation, Compressed Gas is taken over 26 from Compressed Gas and is got into cylinder 25, promotes piston and drives pull bar 22, and drive crank mechanism 20 opens case lid 5 or cuts out.If in the cleaning workpiece process, break down, the compressed air in the cylinder 25 disappears, and spring 23 loses constraint, makes screw thread Y-piece 21 drive crank mechanism 20 immediately and closes case lid 5, prevents outside radgas or the liquid.Guarantee the security of operating process.
As shown in Figure 5, the air vent 7 of a circle is opened on case lid 5 tops, and sealing gasket of air vent 7 usefulness 30 and sealing plate 28 sealings compress sealing plate 28 with a general active grab 27 above, and active grab 27 is fixed by bolts on the hold-down support 29 of case lid 5.
In the practical operation, before cleaning decontamination, active grab 27 is opened with equipment; Remove sealing plate 28 and sealing gasket 30, the circular air vent 7 on case lid 5 just is in opening like this, when equipment is worked; Ventilating system is in opening, and air flows to casing 6 inside from air vent 7.The unlatching of air vent 7 has avoided forming in the casing 6 negative pressure.When equipment out of use, sealing plate 28 and sealing gasket 30 to be put well, active grab 27 is in place.Equipment ventilates when stopping like this, and device interior and isolate from outer air can guarantee that gas can not leak yet in the case.
As shown in Figure 6; Case lid 5 is connected with crank mechanism 20 through bolt; Crank mechanism 20 is connected with rotating shaft member 31 on the airduct bearing 33 that is fixed on airduct 35 tops, and the air-valve pull bar 38 of rotating shaft member 31 through being in casing 6 outsides is connected with air-valve switch 36 from airduct 35 bottoms, and air-valve switch 36 links to each other with air-valve baffle plate 37; Air-valve switch 36 and 60 ° of air-valve baffle plate 37 written treaties, airduct 35 inside upper part have been opened an air port 34.
When uncapping, through 38 motions of air-valve pull bar, promote 36 actions of air-valve switch, air-valve baffle plate 37 is opened gradually, arrives the upright position, airduct 35 smooth and easy air drafts.When the pass was covered, principle was identical, and final air-valve baffle plate 37 arrives obliquities.
The course of work of decontamination box of long workpieces of the present invention: before the cleaning workpiece, open ventilating system earlier, prevent that radgas from leaking from casing.Through the switch cover system, open case lid 5, be placed on workpiece on the work rest 4, close case lid 5, feed the chemical solution that configures through feed tube 2, start supersonic oscillations box 8, the heating chemical solution cleans.If cleaning part is less, insert dividing plate 9, can clean three parts simultaneously.After cleaning finished, the emptying cleaning fluid was opened case lid 5, took out parts.
