A kind of novel thermosensitive material spray of the utility model drying machine, its technological process is:
Feed liquid in batch can 12 pumps into pipeline by screw pump 13, arrive in atomizer 15, feed liquid is become to minimum vaporific drop feed liquid main drying 11 is interior, with hot-air stream, contact, moisture evaporates rapidly, become dry powder and hot and humid waste gas, the lower end discharge hole for discharge of dry powder arrival main drying 11 enters in dehumidifying wind blast system swirl valve 42 mostly, the part fine powder enters cyclone separator with hot and humid air, separate with secondary cyclone 192 by primary cyclone 191, also entered in dehumidifying wind blast system pipeline by two flap valve 43 dischargings.From secondary whirlwind 192, hot and humid waste gas out is drawn out to water dust scrubber 20 by air-introduced machine 182, after purifying by water film dedusting, waste gas is discharged.
Imitate filter and filter 21 and filter the junior middle school of air before by dehumidifier, entering cooled dehumidifier unit 41 is dehumidified, be blown in high efficiency particulate air filter 23 and filter by air curtain air blast 22 again, then be divided into three tunnels by pipeline, the air curtain mouth of the straight bucket top and bottom of main drying 11 is led in its Zhong Second Road, coolingly with the straight bucket of main drying 11, with the cone inwall, contacts dry powder, makes dry powder because of hot mastication, not glue wall, can smooth discharging, the air curtain air force can be regulated by air register 24; Third Road connects the dehumidifying wind blast system except clammy dry-air blast, be connected to swirl valve 42 air inlets at the discharging opening place, lower end of main drying 11 by air delivery pipe, the lower end discharging opening dry powder out of main drying 11 being separated to lower pair of flap valve 43 dry powder out with secondary cyclone 192 with primary cyclone 191 carries out cooling, wind is delivered to rewinding whirly 45 simultaneously, enter 46 rewindings of rewinding bucket, from rewinding whirly 45, the air-supply of wind out sends in tower by backflow blower fan 44 dry powder that falls in cooling tower.Ventilating air cool drying main frame 11 Inner bucket walls in cold wind chuck in main drying 11, make Inner bucket wall keep the non-caked dry powder of lower temperature, imitate in filter 161 junior middle school that chuck blower fan 31 is delivered to the drying machine main air inlet by the extraction of the hot blast in the cold wind chuck, as dry wind, enter in tower, take full advantage of chuck wind-heat amount, reduce energy consumption.
After spray-drying finishes, main drying 11, primary cyclone 191, secondary cyclone 192, two flap valve 43, pipeline 52, swirl valve 42 and air-introduced machine 182 will clean up.Warm water tank 56, buck tank 57 are connected to scavenging pump 55 with the water in clean water tank 58 by pipeline valve, scavenging pump 55 pumps into the water pressurization in pipe blow-through, cleaning by multichannel cleaning head and 51 pairs of dryer system multi-rounds of the interior rotating wash bowl of main drying 11, reach the purpose cleaned up.Clean backwater in surge tank 53, be pumped back to respectively in warm water tank 56, buck tank 57 and clean water tank 58 by circulating pump 54, reach the purpose that recycles water saving.After having cleaned, whole flow process finishes.
A kind of novel thermosensitive material spray of the utility model drying machine, the function of each system is as follows:
Cold wind chuck system: the inner barrel wall of main drying 11 is forced cooling, made powder should not glue wall.
Main drying 11 minutes straight bucket dryer section and cone cooling section: the pattern that the break the normal procedure straight bucket of main drying 11 and cone complete machine are the heated-air drying district, make main drying 11 set up epimere heated-air drying district, stage casing wind outlet area and hypomere cooling zone separately, be equipped with suitable main frame diameter, air curtain cooling system and cold wind chuck system, heat sensitive material is cooled to below melt temperature point afterwards in the short time drying at once, dried dry powder directly falls into the cooling section cooling discharging, does not glue wall, does not lump.
The air curtain cooling system: the position of easily piling up material at main drying 11 arranges ring wind air curtain, forces to purge cooling powder, makes that it is not piled up, easily discharging.
Dehumidifying wind wind send cooling system: material out all enters the cold wind blast system at the bottom of drying tower and at the bottom of whirlwind, rapid, thorough cooling dry powder, and be transported to clean room and a bit concentrate rewinding.Wind after the rewinding cooling dry powder of cooling section in tower of blowing back guarantees that the tail powder reclaims again simultaneously.
Discharge method: master's rewinding at the bottom of the employing tower, the rewinding of series connection whirlwind secondary, three grades of rewindings of water film dedusting, before the raising water film dedusting, capture rate >=95% of dry powder, also improve total capture rate and reach 99% simultaneously.
Water dust scrubber 20: main drying 11 air-out, by the wet trapping tail of water dust scrubber 20 powder, are discharged after udst separation.
This main drying 11 has solved the difficult problem of the disposable spraying drying powder-forming of heat sensitive material; the continuous drying time is long, and (conventional dryer needs the clear tower of the shutdown of discontinuity; then operation is dry again), output is high, and the one-pass finished rate is high; the color and luster of finished product, quality all are better than the product of conventional dryer; omit the operation of pulverizing again after the conventional dryer drying, saved cost and personnel, avoided the secondary pollution of finished product; greatly reduce labour intensity, avoided the clear tower work of conventional dryer able-bodied labour.The product energy primary drying that makes some conventional dryer can not be dried to powder becomes powder, to the user, brings considerable economic benefit, successively in FOS industry, yeast industry and Chinese herbal medicine industry successful Application, is subject to user's consistent favorable comment.
The foregoing is only the preferred case study on implementation of the utility model drying machine, be not limited to the utility model patented technology.Although with reference to previous embodiment, the utility model technology is had been described in detail, for the technical staff of our factory, its technical scheme that still can put down in writing aforementioned each embodiment is improved, or part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in the protection domain of the utility model technology.
