Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, a kind of heated-air drying screening plant, including feed inlet 2, screen box 3, pedestal 1, sieve plate 4, vibration electricity
Machine 5, screen box 3 are in hollow box body shape, are fixed on pedestal 1, and feed inlet 2 is arranged in the side of the top of screen box 3, and material is from screen box 3
The opening discharging of other side setting.Optimal, feed inlet 2 totally three, in shape is distributed side by side, multiple feed inlets 2, which are arranged, to be had
The reduction of effect charging when because put into it is excessive caused by clogging, increase multiple feed inlets 2, material can be made by multiple roads
Diameter enters screen box 3, effectively avoids blocking, and increases powder feeding efficiency.Meanwhile it is close in discharge port side setting shelves dirt curtain sealing strip
Envelope, can effectively reduce dust leakage.
The inside of screen box 3 is obliquely arranged in sieve plate 4, and is higher than discharging one close to the horizontal position of 2 side of feed inlet
Side is connected with the vibrating motor 5 that 3 top of screen box is arranged in.3 two sides of screen box are fixed using reinforcing rib 12, can increase screen box 3
Rigidity, reduce the screen box 3 because of caused by the shaking of sieve plate 4 when screening materials carrying and rock, significantly increase safety.Reinforcing
The lower section of muscle 12, it is fixed with pedestal 1 using damping spring 13, cushioning effect can be played, screen box 3 is avoided when screen box 3 vibrates
Collision between pedestal 1 and screen box 3 is caused to damage.
Further include screenings transmission belt 6, oversize transmission belt 7, sack cleaner 8, expand air port 9, gas pipeline 10, air draught
Machine 11, the screenings transmission belt 6 is horizontal, is through to its opposite discharging side, and horizontal position from 3 pan feeding side of screen box
It sets and is set lower than sieve plate 4, sieve plate 4 is oblique, it is ensured that material can pass through vibrating motor 5 when falling on sieve plate 4
Effect of vibration and it is constantly mobile to lower side.The oversize transmission belt 73 discharge port one end of screen box outside in sieve
The top of lower object transmission belt 6 is vertically arranged with screenings transmission belt 6, and the horizontal position of oversize transmission belt 7 lower than sieve plate 4 compared with
Low one end, material can be fallen in oversize transmission belt 7 by the lower side of sieve plate 4.Do not have to filter sieve plate 4 above sieve plate 4
Material is transported collection by oversize transmission belt 7, falls in screenings transmission belt 6 across the material of sieve plate 4 and is transported receipts
Collection, the different material of granule size divide two-way to be transported, and avoid and separate insufficient phenomenon.
The gas pipeline 10 penetrates box house by 3 top of screen box, introduces hot wind outside screen box 3, using air blower, adds
Hot device and drying box introduce dry hot wind, enter screen box 3 by pipeline and are connected with the expansion air port 9, and gas pipeline 10
It will not be vibrated therewith because of the vibration of screen box 3.Expand 9 air-out direction of air port perpendicular to sieve plate 4 and expands 9 position of air port on sieve plate 4
Side expands the contact area that air port 9 can make the hot wind being sent into expand it with material, improves the efficiency of dry materials.Appendix
Multiple groups are arranged in road 10 and expansion air port 9, and expand air port 9 and be evenly distributed above sieve plate 4, setting multiple groups gas pipeline 10 and expansion air port
9 can more be passed through dry hot wind, and each position on sieve plate 4 is blown to by hot wind simultaneously, is further speeded up
The uniformity coefficient of dry materials.
The suction ventilator 11 is fixed at the 3 internal side wall position of screen box between sieve plate 4 and screenings transmission belt 6, then
It extends to 3 outside of screen box by pipeline to be connected with the sack cleaner 8 being fixed on pedestal 1, thus position outlet.Suction ventilator
11 the humid air in screen box 3 is sucked out, and by the processing of sack cleaner 8, further speeds up the rate of drying of material.Pocket type
The junction of deduster 8 and sieve plate 4 is flexible coupling using high temperature resistant canvas, also plays the function of shock insulation and heat insulation.
The course of work of apparatus of the present invention are as follows: the material that moist and needs sieve is put by feed inlet 2, falls to sieve plate
The higher side in 4 horizontal positions, simultaneously as the effect of vibrating motor 5 so that material is shaken and is spread out, and to horizontal position compared with
Low side is slowly moved, and the large granular materials stayed on sieve plate 4 are fallen in oversize transmission belt 7 along inclined sieve plate 4, warp
The small particles material for being sieved through sieve plate 4 is fallen in screenings transmission belt 6, and two paths is divided to be transported collection.Meanwhile defeated
Feed channel 10 introduces dry-heat air, and into inside screen box 3, by the absorption of suction ventilator 11, the air for being mingled with moisture is absorbed into
In sack cleaner 8 outside screen box 3, it is then exhausted from device, so that drying efficiency is accelerated.
