Embodiment
Shown in Fig. 1 to 3, according to the heat treatment furnace of present embodiment with the jet flow refrigerating unit comprise recirculation blower 2 with blast inlet 21 and air outlet 22, air-cooling chamber 1 that top is connected with the blast inlet 21 of recirculation blower 2, be arranged on the plummer 8 that is used for place work piece in the air-cooling chamber 1, be arranged on the heat exchanger 6 that is positioned at plummer 8 tops in the air-cooling chamber 1, be arranged on spray wind body 3 that air-cooling chamber 1 is positioned at plummer 8 tops, two ends are respectively with the air outlet 22 of recirculation blower 2 with spray the second passage 5 that first channel 4 that wind body 3 is connected, two ends are connected with the bottom of the air outlet 22 of recirculation blower 2 and air-cooling chamber 1 respectively.
Referring to Fig. 3 and Fig. 4, spray wind body 3 comprises that lower plate 33, lid are located at upper plate 34 on the lower plate 33, are opened in a plurality of on the lower plate 33 spray wind hole 31 and having towards plummer 8 and are positioned at both sides and a plurality of return air channels 35 that distribute along the length direction of said lower plate 33.Carry the wind of coming to be ejected into the top of workpiece downwards from spray wind hole 31 from first channel 4; Afterwards; Come back to the upper space of air-cooling chamber 1 with hot blast after the workpiece generation heat exchange from the return air channel 35 of both sides, after over-heat-exchanger 6 heat exchange, convert cold wind into and get into recirculation blower 2.Spray wind body 3 is divided into a plurality of spray wind zone 32 of arranging along its length direction; The arrangement of embarking on journey of spray wind holes 31 in the spray wind zone 32 of each spray wind body 3; Spacing between the two adjacent spray wind holes 31 in each row equates; Stagger each other between the spray wind hole 31 of adjacent two row, the distribution density in spray wind hole 31 is successively decreased towards the direction of discharge end from feed end successively.Thereby the spray air quantity that layout like this can improve feeding side improves the speed of cooling of the workpiece of this side, to reach the requirements at the higher level of thermal treatment process to the leading portion speed of cooling of workpiece.The direction of axis line of return air channel 35 and the angle between the vertical direction can be between 0 °～45 °, and the angle of a plurality of return air channels 35 can be identical or different, in this example; Direction of axis line and the angle between the vertical direction near the return air channel 35 of feed end are 0 °; Direction of axis line and the angle between the vertical direction near the return air channel 35 of discharge end are 45 °, so, can strengthen the return air amount of feeding side; Form the air-flow of contrary feedstock direction, accelerate the speed of cooling of workpiece leading portion.
In addition, can on first channel 4 and second passage 5, establish valve 11 to regulate the flow of wind.
It is following to take present embodiment that workpiece is carried out the refrigerative working process:
At first; Shielding gas gets in the lower space of spray wind body 3 and air-cooling chamber 1 respectively through the recirculation blower 2 of sealing along first channel 4 and second passage 5; Can regulate the air quantity that gets into spray wind body 3 and lower air chamber 10 this moment through control air-valve 11; To guarantee that the jet flow refrigerative is balanced up and down in the air-cooling chamber 1, avoid workpiece to be out of shape because of inhomogeneous cooling.Along with conveying belt 7 gets into the workpiece in the air-cooling chambers 1, when moving between spray wind body 3 and the plummer 8, can be by from cooling off in the spray wind hole 31 of spray wind body 3 with from the refrigerative shielding gas that the through hole 81 of plummer 8 sprays; These fast cold wind will be sprayed on the upper and lower surface of workpiece, formed efficiently convective heat exchange on the workpiece surface this moment, cold wind is taken away the heat on the workpiece fast; Make the workpiece fast cooling, cold wind becomes hot blast owing to having absorbed the heat on the workpiece, after water wall 9 coolings; Get into upper space from return air channel 35; After heat exchanger 6 further coolings, change cold wind into, get into recirculation blower 2; Recirculation blower 2 is sent to this part cold wind in first channel 4 and the second passage 5 through air outlet 22 again, and cold wind carries out recycling.Because it is big than the discharge end place that the distribution density of spray wind hole 31 and through hole 81 is the feed end place; And return air channel 35 and workpiece feedstock direction are at an angle, changed the wind direction in the turnover air-cooling chamber 1, thereby change the distribution of air quantity in the air-cooling chamber 1; After guaranteeing that workpiece gets into the jet flow refrigerating unit; Have rational cooling curve, have enough cooling intensity, guarantee that it is the requirement of required best speed of cooling technology that workpiece is heat-treated.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
