Description
Technical field
The present invention relates to a kind of heating power drying equipment, particularly a kind of numerically controlled fluidized rotary floating drying machine that is suitable for dry cake shape, high humidity and thermal sensitivity powder body material.It is mainly used in the dehydrating of accessory substance of agricultural product such as pomace, dish slag, soybean residue and vinasse, so that as the be mixed raw material of feed of processing.Also can be used for the dry precipitation of deep processing powder material and the dehydrating of the Chinese medicine preparation extract through concentrating of potato, Chinese yam, pumpkin and other fresh fruit of vegetables etc. of agricultural product.
Background technology
In recent years, along with the develop rapidly of China's economic construction, need dry material more and more; Inter-trade field is more and more deep; The kind that relates to more and more widely; Equipment quality requires more and more stricter; Material baking back quality required precision is more and more higher.The defective that heat waste is big, energy consumption is high, accident rate is many, maintenance difficulty is big that " the tray drying method " of traditional baking room, drying baker, steam-boiler steaming etc., old-fashioned flash drying equipment etc. exist is suddenly waited to improve to improve.
Existing a lot of Chinese medicine preparations are to follow traditional technology, with the extract of producing, form through concentrated, dry, pulverizing, screening.Wherein toast and generally want more than 10 hour even more than 20 hour drying time, heat loss is very big, the cost height, and efficient is low.At present, the accessory substance pomace after the deep processing of farm products, dish juice slag, soybean residue, vinasse etc. wherein are rich in compositions such as a large amount of crude protein, crude fibre, crude fat, calcium, starch, magnesium, potassium, sodium, iron, phosphorus, are free of contamination natural green article.They all are the raw materials that is mixed of the first-class feed of livestocks such as ox, sheep, pig.But why fruit and vegetable dreg, resource such as poor go out of use mostly for a long time, main cause just is that these byproducts are difficult to storage when fresh, if handle untimely will go rotten rotten, livestock has eaten rotten byproduct and then has been harmful to health, it is thrown away not only wastes natural ecological resources, and serious environment pollution, make the ecological resources that have high added value originally but therefore become pollution sources.In recent years, began industrial crops such as large-area plantation corn, sweet wheat, potato, pachyrhizus, pumpkin, capsicum, often be subjected to all multifactor restrictions such as selling market, though having got bumper crops of having just do not have rich extra earning but can not be sold.If these products are suitably handled, become ecological raw material with high added value, then the potentiality of Sheng Zhiing will show at once.
China falls behind the treatment technology means of pomace at present, mainly takes ensiling way to handle.Be preferred first-class pomace, remove impurity, in the kiln that digs in advance of packing into, will cover polybag, soil and straw after compacting installs, treat to enable after 40 days.Because this method is in practice, the possibility that pomace goes mouldy is very big, so, must arrange every day the special messenger to observe situation in the kiln, subside in case seal to break or cheat the cellar for storing things, will cause damage.Once there was the people that this method is improved, and added active bacterium and adopt the method for many kilns microbiological treatment to apply.This improvement is the preservation that short-term prolongs pomace, still has the defective that can't overcome, and perishable as storage in the cellar for storing things, materials quality can't guarantee; Material buries in the cellar for storing things for a long time, and the effect of enzyme and active bacterium can change organic principle in the material, reduces original quality, reduces resource utilization; The material proportion of resources such as pomace is little, volume is big, and it is many that occupation of land is buried at the cellar for storing things, not suitable for the area that cultivated area is few relatively.Therefore, this method far can not adapt to the needs of China's ecological agriculture development.As everyone knows, fruit and vegetable dreg is handled through super-dry, can prevent enzymatic browning, but long term storage keeping again, convenient transportation.Significantly increase economic efficiency than the horizontal silo method of hiding, and reduce occupation of land, alleviate labor strength, reduce cost of transportation, increase the storage sense of security.Practical experience shows, pomace, dish slag have only through low temperature rapid draing to be handled, could be economical, effectively keep its organic matter and nutritional labeling, promote its added value.What general wet method was sold is 4～25 yuan/ton, and the fruit and vegetable dreg dry product that adopts low temperature rapid draing to handle, its price can reach 800-1200 unit/ton.Because fruit and vegetable dreg, poor special substance characteristics determined that its attribute is a thermal sensitivity, and common hot drying plant are difficult to guarantee that its nutritional labeling is not destroyed, also difficulty reaches above-mentioned drying effect and obtains favorable economic benefit.
For this reason, all at the various flash drying equipments of research, their structure is basic identical, all exists the equipment failure rate height in the home and abroad, problems such as maintenance difficulty.Mainly be that its design is unreasonable, parts matching requirements precision is too high, big, time-consuming, the effort of assembly dismounting difficulty, and reasons such as the high-temperature area parts are very easily aging, bearing leakage of oil, bearing shell seize cause.
At present, the same category of device that can handle filter cake shape, high humidity, thermal sensitivity powder body material in the external dry technology mainly is a Rotatingandflashstreamingdrier, and it is used in chemical field the eighties in 20th century.Spray dryer is bulky though this equipment has effectively overcome, the defective of high energy consumption, has remedied the uneven deficiency of existing fluidized drying machine precipitation.But still have certain problem on structural design: first main shaft bracketed part is long, and axle suspension arm length overall is 5: 3 with the ratio that axle supports brachium, presents the unreasonable situation of " head greatly, neck is long, body is short ".Be the length that two spring bearing spacings of main shaft are far smaller than the axle suspension arm.In order to prevent the head swing, set up a place's bearing shell and a stent support at the reverse taper place, be difficult to guarantee by the stirring head of bearing shell and support location and concentricity, the axiality of spring bearing; Head is high load capacity work in addition, therefore, increase power source, and this is an excessive factor of power configuration.Simultaneously, under 300 ℃ high-temperature condition, be easy to occur thermal deformation, the seize accident takes place.It two is combinations that main axis transmission system mostly is scattered parts, and the allowable tolerance in some component processing processes has formed accumulated tolerance with the fit tolerance of some bolts in the combination assembling process; Motor adopts orthogonal and by the troughed belt transmission in addition, and the tension of troughed belt has made above-mentioned stirring head move to side is biased under the situation of high capacity in the transmission process, and leaf fin one side that causes head to drive is scraped barrel.For addressing this problem, having only increases power source again, and the phenomenon that the head rotation is obstructed for this reason, troughed belt is broken or solid accumulation crashes happens occasionally.It three is positions that the bottom of reverse taper promptly contacts with bearing, is the high-temperature medium operation area.This place had not both had heat preserving and insulating material, also without any the measure condition of cooling bearing, high temperature heat source continuously passes through bearing shell and the outside high-speed transfer of support thereof, leakage, can cause the leakage of oil of bearing high temperature, components aging, damage of bearings, bearing shell seize or increase unnecessary serious consequences such as heat loss.It four is that the leaf fin structure of stirring head is unreasonable, do not have scrape, broken, throw three kinds of functions.The gusset of this leaf fin is the parallel construction of horizontal, only scrape, broken effect, run into the material of the big moisture of high thickness, centrifugal the rotatablely moving of stirring head high speed water flat, material is getting rid of to wall along the gusset level just, high temperature moment of 300 ℃ is passed to wall in the air compartment, and material just is bonded on the wall firmly.The leaf fin does not stop scrapes wall, and the sticking wall that material does not stop again certainly will increase power again.The material gelatinization will appear in the lighter like this, and weight person's buildup is built wall, will cause the serious consequence of stopping production.It five is in view of above-mentioned all multifactor reasons, is to improve device start efficient, occurs the phenomenon of unnecessary low load with strong power on the power configuration, causes energy waste.It six is because of transmission system mostly is loose mail combination, so cause the loading, unloading difficulty, the drawback of maintenance difficulty.Therefore, the structure of this device is anxious waits to improve.
The Rotatingandflashstreamingdrier great majority of domestic production are to introduce technology, and all have the problems referred to above basically.For example, report according to Chinese patent literature, the patent No. is 94231479.4 " injection flash dryers ", be to be improved on the basis of vertical helical flash dryer of 91222567.X in the patent No., this machine has overcome its existence, and " mechanical transmissioning piece processing request precision height occurs leakage of oil easily, leaks the material problem.With high temperature (more than 300 ℃ time) heated-air drying the time, the lubricating oil in the bearing holder (housing, cover), seals etc. can be rotten aging, defectives such as seize occur.In addition, this patent is owing to still adopt the method for the dry precipitation of traditional high-pressure hot wind, and material and air-flow in it are parallel type, drying efficiency is reduced, so energy consumption is bigger.The patent No. is 98227314.2 " Rotatingandflashstreamingdrier ", is provided with spinning disk in the main tower of this device, adopts the air intake volute with pressure stabilizing cavity, can improve the utilization rate of hot blast.In main tower charging place, be provided with water-cooling jacket, the tower wall temperature reduces, and is difficult for gluing wall by the humidity material after pulverizing, can coking yet, solved the problem of sticking wall coking.But this device not only will increase the power for water recirculation facility, also will increase equipment manufacturing cost, has also wasted the energy simultaneously.As you know, under certain environmental condition, the high temperature material is fastest to the transfer of cryogenic substance heat, dried material and water-cooling jacket all are under same environmental condition, drum dryer inner drying material needs the heat of higher temperature, the recirculated water of cryogenic media is wanted the available heat of absorption dehydration material, and dried material takes the production that did not stop in 24 hours in one day, the heat supply that does not stop.So, cooling circulating water also takes one day 24 hours absorption heat of not stopping, and adds up, and the loss and waste number of heat is surprising.This water-cooling wall chuck is the great cost with the great number heat loss, solves the minor issue of the sticking wall of coking and loses more than gain.Therefore, existing drying equipment need improve the effective rate of utilization of heat, to reduce operating cost, reduces heat loss to greatest extent, cuts down the consumption of energy.
