Description
Technical field
The utility model relates to a kind of drying device, specifically the large-scale drying tower of air draft on the pressure type.
Background technology
At present, drying tower all is used widely in fields such as dairy products, beverage, starch sugar, fruit juice jam, biochemical pharmacy, honey refining, soybean deep processing, food additives, sewage disposals.Ordinary circumstance can be fan-drying tower on the tower body, tower body bottom expansion fan-drying tower, tower awl end mouth big syphon fan-drying tower according to drying tower air draft form branch.Current production devices exists efficient low, and the dust wall built-up is serious, and the uneven problem of bringing owing to atomizing effect is bad of finished particle.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and the large-scale drying tower of air draft on a kind of pressure type is provided, and has the efficient height, and dust wall built-up situation is light, the good characteristics of liquid material atomizing effect.
The technical scheme in the invention for solving the technical problem is: the large-scale drying tower of air draft on this pressure type, comprise drying tower, cyclone separator, sack cleaner, atomizer, rotary screen, sub-sieve and material storing box, it is characterized in that, described drying tower is small top and big bottom taper tower, there are import of liquid material and high-pressure hot wind import in the upper surface, there are branch wind apparatus that is connected with the high-pressure hot wind import and the many spray guns atomizer that is connected with the import of liquid material in inside, circumferential uniform a plurality of suction opeings on the wall, the lower end of drying tower is a discharging opening, and the awl of drying tower saves bottom that inside is provided with pneumatic hammer; Suction opeing on the drying tower wall connects cyclone separator through air exhauster, the awl joint mouth of cyclone separator is connected on the drying tower, the awl joint foot of cyclone separator is provided with pneumatic hammer, and the top outlet of cyclone separator is connected to sack cleaner, and the awl joint foot of sack cleaner is provided with pneumatic hammer; The discharging opening of drying tower is connected to rotary screen through delivery pump and cooling pipe, and the awl joint outlet of rotary screen is connected to material storing box through sub-sieve.
The beneficial effects of the utility model are: the large-scale drying tower of air draft adopts many spray gun structure designs on this pressure type, and the droplet of each spray gun ejection collides mutually, aggregates into the bulky grain of hollow, has improved the instant capacity of dusting.High-pressure fog, the droplet of each spray gun ejection collides mutually, aggregates into the bulky grain of hollow, and material fully atomizes, and fully contacts with hot blast, has increased heating surface area, has improved the thermal efficiency, the product wink-dry.Divide wind apparatus to adopt a plurality of adjustable air ducts, guarantee to enter the interior air-flow of tower vertically downward, not bias current, no eddy current.So just reduced the dust wall built-up to greatest extent.Air draft on the multiple spot is partly adopted in air draft, and wind arrives the bottom and forms big revolution, has increased the drying time of material, has effectively utilized hot-air.The equipment air draft is even, has reduced the dust wall built-up, and the dust folder amount that enters cyclone separator reduces, and improves the product yield.The fine powder of cyclone separator becomes larger particles through getting back to agglomeration in the tower from cat head again, has improved the solubility of dusting, and has protected environment simultaneously.Awl at drying tower saves, the awl of sack cleaner saves and the awl joint foot of cyclone separator is provided with pneumatic hammer, adopts pulse control instrument to make its intermittently sequence starting, and timely and effective shake falls to boring the accumulated powder that saves.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 drying tower, 11 liquid material imports, 12 high-pressure hot wind imports, 13 fens wind apparatus, 14 suction opeings, 15 pneumatic hammers, 2 cyclone separators, 21 times air exhausters, air exhauster on 22,3 sack cleaners, 4 atomizers, 5 delivery pumps, 6 cooling pipes, 7 rotary screens, 8 sub-sieves.
The specific embodiment
As shown in Figure 1, the large-scale drying tower of air draft on this pressure type comprises parts such as drying tower 1, cyclone separator 2, sack cleaner 3, atomizer 4, rotary screen 7, sub-sieve 8, material storing box.
The lower end of drying tower 1 is a discharging opening, and the awl of drying tower saves bottom that inside is provided with pneumatic hammer 15, and pneumatic hammer 15 adopts pulse control instruments to make its intermittently sequence starting, the fall accumulated powder of awl joint of timely and effective shake; The discharging opening of drying tower 1 is connected to rotary screen 7 through delivery pump 5 and cooling pipe 6, and cooling pipe has the effect of cooling material, and the awl joint outlet of rotary screen 7 is connected to material storing box through sub-sieve 8, can obtain the product of different grain size requirement.
Its course of work is, feed liquid becomes the bulky grain droplet of hollow through 4 dispersin polymerizations of many shower nozzles atomizer under the effect of extraneous power, droplet has very big surface area, when with when the hot blast air contacts, owing to divide wind apparatus 13 to adopt a plurality of adjustable air ducts, guarantee to enter the interior air-flow of tower vertically downward, not bias current, no eddy current, thus the rapid vaporization of the moisture in the droplet is dried to powder; Reduced simultaneously the dust wall built-up to greatest extent.Air draft on the multiple spot is partly adopted in air draft, and wind arrives drying tower 1 bottom and forms big revolution, has increased the drying time of material, has effectively utilized hot-air; Equipment air draft simultaneously is even, has reduced the dust wall built-up; The dust folder amount that enters cyclone separator 2 reduces, and improves the product yield.The part fine powder is entrained in the waste gas and arrives cyclone separator 2 by the suction opeing on the drying tower 1 through air exhauster, under the big rotating effect of annular air curtain 180 degree in cyclone separator 2, the fine powder product is separated from waste gas, enter in the drying tower 1 by awl joint mouth, realize the purpose of recovery, waste gas can allow compliance with emission standards carry out emptying through fiber bag precipitator 3 again behind cyclone separator 2.Under delivery pump 5 effects, enter rotary screen 7 after dry products comes out from drying tower 1 discharging opening, the particle of different-diameter can be separated by rotary screen 7 and sub-sieve 8, and enter in the corresponding material storing box through cooling pipe 6.
