Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, powder flow heat exchanger, comprise the feeding warehouse 1 set gradually from top to bottom, heat exchanger plates case 2, discharging bin 3, heat exchanger plates case 2 comprises multiple heat exchange plate, separating screen device is provided with in feeding warehouse 1, feeding warehouse 1 sidewall is provided with clean-up port 11, separating screen device comprises floor group 12, floor group 12 comprises the consistent floor of multiple incline direction 121, the comparatively low side of floor 121 is located in clean-up port 11, the lower limb of clean-up port 11 is not higher than the top edge compared with low side of floor 121, maximal clearance between adjacent floor 121 is less than the minimum clearance between adjacent heat exchange plate.
This powder flow heat exchanger, powder material enters the sub-sieve first through separating screen device between heat exchanger plates case 2, because the maximal clearance between adjacent floor 121 is less than the minimum clearance between adjacent heat exchange plate, block so can not cause between heat exchange plate, thus improve heat exchange efficiency.
The angle of inclination of floor 121 is all consistent, and floor 121 is greater than the angle of repose of the powder material treating heat exchange with the angle of horizontal direction, ensures that the powder material of caking drops down onto clean-up port 11 along floor 121.
Heat exchange plate is the ripple struction of two sides symmetry, increases heat transfer area, ensures higher heat transfer efficiency.
As shown in Figure 4, purging structure is provided with in heat exchanger plates case 2, purge structure and be located at the top of heat exchange plate, purge structure and comprise multiple main pipeline 21 be arranged in parallel, the axis horizontal of main pipeline 21 and one end are closed the other end and are communicated with dry air, main pipeline 21 is provided with multiple aperture towards the side of heat exchange plate, dry air flows out from aperture, blows to heat exchange plate, takes away the moisture in powder material, prevent from scabbing, extend cleaning period.
As shown in Figure 5, being provided with many group relative tilts in discharging bin 3 is reverse V-shaped screen 31, between screen 31, there is gap, discharging bin 3 both sides are respectively equipped with two vibrating motors 32, powder material flows out from the gap bottom screen 31, as explanation, another vibrating motor 32 in accompanying drawing 5 is blocked by visible this.
When two vibrating motors 32 reversely rotate, producing vibration, by regulating vibration frequency, making powder material uniform speed slow flowing in heat exchanger as much as possible.
Reach best for making heat transfer effect, the discharging actual internal area of powder flow is 1.2 to 1.5 times of charging actual internal area, wherein, the discharging circulation area of powder flow, being exactly powder material from the discharge area flowed to next workshop section between the screen 31 of discharging bin 3, drawing by calculating the area sum of enclosing between all adjacent screen 31 of material outlet position; The charging actual internal area of powder flow, the area that the mouth of pipe being positioned at the charging adapter 4 at feeding warehouse 1 top exactly encloses.
Water supply connector 22 and the water out adapter 23 of heat exchange plate are equipped with Taper Pipe internal thread, and arranging internal thread is screw thread in order to not damage during dismounting on joint, effectively prevent because screw thread damages the product rejection caused, and adopts taper pipe thread structure to be in order to good sealing effect.
