15 1 groups on per 2 rollers are installed in respectively wheel shaft 28 two ends with baffle plate 27, and roller 15 spacings are corresponding with slide rail 7 spacings arranged side by side.
Fig. 6 is the perspective view of the utility model hanger support, as shown in Figure 6, the deep cooling paint removal equipment of described spraying hanging tool, the rectangle frame of its hanger frame 6 are formed with for 16 times and land the framework 18 of leg 17, and framework 18 1 side right angles connect and prevent the side rack 19 that hanger tumbles.The cross bar of side rack 19 is consistent with the length of rectangle frame 16 and framework 18, and the vertical rod bottom of side rack 19 forms lands leg.
Fig. 5 is that the utility model is in conjunction with the perspective view of chamber door rear box, as shown in Figure 5, the deep cooling paint removal equipment of described spraying hanging tool, case mouth two lateral walls of its casing 1 are provided with the screw 21 with the corresponding combination of chamber door 2 both sides bolts, 20 1 ends, and the other end of chamber door 2 both sides bolts 20 is combined in the center of handle panel 22.
Fig. 3 is the perspective view of the utility model casing, and Fig. 4 is the planar structure schematic diagram of the utility model box mouth, and Fig. 9 is the utility model box inside wall liquid nitrogen pipe distribution schematic diagram.
As shown in the figure, the deep cooling paint removal equipment of described spraying hanging tool, its liquid nitrogen spraying pipe 4 is communicated with on 1 liang of madial wall of casing and interior rear wall in same level, and arranges at least 2 at a certain distance, is formed with most spray apertures (not shown) on the liquid nitrogen spraying pipe 4.Casing 1 outer pipeline 3 connects liquid nitrogen storage tank (not shown) through valve.
The deep cooling paint removal equipment of described spraying hanging tool, its casing 1 and chamber door 2 are that thermal insulation plate 23 consists of in conjunction with reinforced bulkhead 24 one.
What the deep cooling paint removal equipment of described spraying hanging tool, 2 arranged side by side of slide rail 7 same planes of its support skid 5 and hanger frame 6,7 of slide rails were formed with keeping parallelism arranges pole 25, and slide rail is formed with the support 26 fixing with the 1 interior end of casing for 7 times.
The depth of described casing 1 is greater than box height and casing width.
The utility model sample, the housing 3000*1600*1900mm of casing 1, inwall are 2800*1200*1400mm,
Spray apertures DN2.5MM on the liquid nitrogen spraying pipe 4, pitch of holes: 200mm, liquid nitrogen spraying pipe 4 shape of bowing is U-shaped, spray apertures quantity: 64 holes.
When the utility model of design uses like this, chamber door 2 is opening, the spraying hanging tool that is covered with residual paint, superimposed code is placed on the outer hanger frame 6 of case, with the slide plate 5 on the case external slide rail (not shown) push to casing 1 in slide rail 7 on, slide plate 5, hanger frame 6 and on spraying hanging tool enter casing 1.Mobile chamber door 2 is to the case mouth of correspondence, and pulley 10 travels to the propelling chute 13 that advances slideway 11 along the chutes 12 under slideway 9, and the handle panel 22 of turn chamber door 2 both sides makes the screw 21 corresponding combinations of bolt 22 and case mouth both sides, chamber door 2 hermetically closing case mouths; Open the valve of casing 1 outer pipeline 3, most the spray apertures of liquid nitrogen gas on liquid nitrogen spraying pipe 4 are cooled off the casing 1 interior space of sealing to casing 1 interior ejection;
By the chilling temperature in the control of the controller (not shown) outside the casing 1 and the monitoring box body 1, chilling temperature is cooled to-189 degree from normal temperature, afterwards gradually along with the injection of liquid nitrogen (LN2) mist, keeping this state of temperature more than 10 minutes, finish subzero treatment again.Outward winding handle panel 22 and bolt 22 affect chamber door 2, make to advance slideway to advance for 11 times the pulley 10 of 13 li of chutes to shift to slideway 9, and chamber door 2 is opened, from slide rail 7 pulling slide plates 5, hanger frame 6 and on spraying hanging tool go out casing 1, get place's spraying hanging tool.
At this moment, residual lacquer on the spraying hanging tool ftractures, even some drops, the spraying hanging tool that takes out, put into hook type shot-blasting machine cavity through suspension hook again, the steel ball that ejects by the shot-blasting machine side impacts through overcooled spraying hanging tool, thereby the residual lacquer that has broken on the spraying hanging tool is destroyed by the steel ball that high velocity jet goes out, realized that finally spraying hanging tool removes the purpose of skin of paint.
Hook type shot-blasting machine (not shown) by Chinese Yancheng dawn machine-building Co., Ltd produces mainly is comprised of projectile cycling system, ventilating and purifying air system, workpiece carrying system, ball blast and sealing system, control system five major parts.The operation principle of shot-blasting machine: bullet enters shot wheel by importing cylinder, is sent on the blade through the orienting cover window, under the effect of high speed centrifugation power, form fan-shaped bullet bundle, impelling is peeled off the oxide skin of surface of the work, iron rust etc. to workpiece, thereby reaches the purpose of cleaning workpiece.
Like this, through the utility model subzero treatment, the spraying hanging tool after shot-blasting machine is processed again, the paint removal effect is very obvious, does not basically see the vestige what residual paint is arranged, and is very clean, and to the original form of suspension member also without any variation.After on probation, check, spraying hanging tool hanger distortion minimizing+/-5mm, the spraying hanging tool material is unchanged, and the spraying hanging tool quality is guaranteed, spraying hanging tool fraction defective 300ppm.
