Detailed description of the invention
As shown in Fig. 1, Fig. 3, Fig. 4, a kind of paint line solidification equipment efficient return air structure, comprise exterior wall 1 and interior wall 2, in the middle of exterior wall 1 and interior wall 2, form return air chamber 3, described exterior wall 1 top is provided with air inlet 4 and air inlet 4 is communicated with interior wall 2 inside, described interior wall 2 sidewalls are provided with return air inlet 5 and return air inlet 5 is communicated with return air chamber 3, described 3 bottoms, return air chamber are recessed to form precipitum collecting region 6 downwards, claim by after powder concentrate on precipitum collecting region 6, be convenient to process, in described return air chamber 3, be also provided with a powder sedimentation mechanism 8 that can make powder sedimentation.
Precipitum collecting region 6 comprises expansion chamber 61, and expansion chamber 61 is provided with some window mechanisms that can open or close 62.Window mechanism 62 is transparent visual window, can observe directly the amount of powder in window mechanism 62, and opens in time window mechanism 62 powder is taken out.
On return air inlet 5 and air inlet 4, be provided with filter screen, and aperture of filter screen on return air inlet 5 is greater than the aperture of filter screen on air inlet 4, filter screen the air quality that can improve air intake or return air is set.
Return air inlet 5 is positioned at the bottom of interior wall 2 sidewalls, and the horizontal level of return air inlet 5 is higher than the horizontal level of precipitum collecting region 6, therefore, enters air-flow in return air inlet 5 and can not confuse the powder of precipitum collecting region 6.
Exterior wall 1 bottom is provided with some adjustable for height legs 7, can be used for regulating the height of total, as raised whole height of the present utility model by raising exterior wall 1, and with in actual production process, adjust.
Powder sedimentation mechanism 8 comprises fixed head 81, and described fixed head 81 tilts and is provided with some deep beads 82, and described deep bead 82 is provided with some discharging openings 83 with the junction of fixed head 81, discharging opening 83 can be poroid can be also strip.
Because deep bead 82 is inclined on fixed head 81, therefore there is an angle between the two, in the present embodiment, the angle between fixed head 81 and deep bead 82 is 30 °-60 °.As the preferred scheme of one, the angle between fixed head 81 and deep bead 82 is 50 °, and according to inclined plate sedimentation principle, in the time of this angle, powder particle is sedimentation to greatest extent.
Deep bead 82 outsides are coated with one deck insulating coating, and insulating barrier can prevent that deep bead 82 is electrically charged, thereby the powder adherence that prevents static is on deep bead 82.
Operation principle of the present utility model is as follows: hot blast enters into interior wall 2 inside from air inlet 4, section bar to interior wall 2 inside heats, make the powder smelting of Surface of profile and solidify, return air enters into return air chamber 3 from return air inlet 5, be back to again in hot air heating apparatus (not shown) and continue to heat, after heating, enter from air inlet 4, thereby form hot air circulation.Because the air inlet 4 of this air return structure is at top, return air inlet 5, at sidepiece, therefore at the inner air-flow that forms " top send side to return " of interior wall 2, thereby makes the temperature at whole interior wall 2 inner each positions keep stable, make the powder smelting of Surface of profile even, reach good solidification effect.
Because the powder of Surface of profile can come off, therefore in return air inevitably with impurity such as powder, if these powder impurity directly enter hot air heating apparatus with return air, can have a negative impact to heater, conventionally need to filter entering before heater, the operations such as screening, and this air return structure is owing to being provided with precipitum collecting region 6, most powder is deposited in precipitum collecting region 6, can directly take out utilization by opening window mechanism 62, very economical material benefit, and because the content of powder in return air reduces, can greatly reduce filtration, the pressure of the operations such as screening.
Powder sedimentation mechanism 8 can fix by fixed head 81 and the metope of exterior wall 1 or interior wall 2, powder in return air is after deep bead 82 stops, form inclined plate sedimentation, and be back to return air chamber 3 bottom depositions along deep bead 82 or discharging opening 83, thereby the particle in return air is significantly reduced, improve the air quality of return air, reduced the subsequent processing steps of return air.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendments or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although more used the terms such as exterior wall 1, interior wall 2, return air chamber 3, air inlet 4, return air inlet 5, precipitum collecting region 6, expansion chamber 61, window mechanism 62, leg 7, powder sedimentation mechanism 8, fixed head 81, deep bead 82, discharging opening 83 herein, do not got rid of the possibility that uses other term.Use these terms to be only used to describe more easily and explain essence of the present utility model, they are construed to any additional restriction is all contrary with the utility model spirit.
