Description

Novel atomizing drying machine

Technical field

This utility model relates to chemical industry technique with the apparatus field, particularly relates to a kind of novel atomizing drying machine.

Background technology

In the production process of auxiliary chemicals, finally need be dried by auxiliary agent and make granular structure, at this time need to use to process to spray dryer, and spray dryer is susceptible to the situation of viscous wall, drying tower wall is persistently blown by conventional processing mode for using air jet pipe, make material will not be bonded in Ta Bishang, but this mode needs an extra aerator, consume too much resource, and the drying regime in persistently air blowing influences whether drying tower, the crystallization to material has certain negative effect.

Utility model content

For above-mentioned situation, for overcoming the defect of prior art, the purpose of this utility model is just to provide a kind of novel atomizing drying machine, effectively solves the problem that in dry run, material glues wall.

Its technical scheme solved is, this utility model includes drying tower, it is characterized in that, drying tower top is provided with centrifugal atomizer, centrifugal atomizer connects feed pipe and blast pipe, drying tower includes inner and outer wall, ventilating layer it is provided with between inner and outer wall, inwall is mobilizable soft material, inner wall is hothouse, hothouse is communicated with cyclone separator, cyclone separator lower end is provided with discharging opening, cyclone separator side forms loop through other return pipe connection, on other return pipe, the first check valve is installed, constituting other return pipe can only be to the structure in formation loop, a direction, the air outlet of cyclone separator connects ventilating layer through ventilation duct, second check valve and compression pump are installed on ventilation duct, ventilating layer connects cleaner unit.

This utility model simple in construction, recycling energy, and reduce the input of equipment, the generation of viscous wall can be significantly reduced so that being dried of material is more thorough, better.

Accompanying drawing explanation

Fig. 1 is schematic diagram of the present utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.

nullBe given by Fig. 1，This utility model includes drying tower，It is characterized in that，Drying tower top is provided with centrifugal atomizer 5，Centrifugal atomizer 5 connects feed pipe 7 and blast pipe 8，Drying tower includes inwall 2 and outer wall 1，Ventilating layer 3 it is provided with between inwall 2 and outer wall 1，Inwall 2 is mobilizable soft material，It it is hothouse 4 inside inwall 2，Hothouse 4 is communicated with cyclone separator 17，Cyclone separator 17 lower end is provided with discharging opening 20，Cyclone separator 17 side forms loop through other return pipe 18 connection，On other return pipe 18, first check valve 19 is installed，Constituting other return pipe 18 can only be to the structure in formation loop, a direction，The air outlet of cyclone separator 17 connects ventilating layer 3 through ventilation duct 14，Second check valve 16 and the first compression pump 15 is installed on ventilation duct 14，Ventilating layer 3 connects cleaner unit 21.

Filter 10 and the second compression pump 9 it is sequentially provided with on described feed pipe 7.

Air filter 13, aerator 12 and heater 11 it is sequentially provided with on described blast pipe 8.

Multiple shower nozzle 6 it is provided with below described centrifugal atomizer 5.

Described drying tower lower end is provided with discharge gate 23.

Air-introduced machine 22 it is provided with between described drying tower and cleaner unit 21.

This utility model in use,

nullFeed pipe 7 connects storage tank，Blast pipe 8 connects outside air，It is then turn on device power supply (DPS)，Start working，The material of liquid enters in centrifugal atomizer 5 through filter 10 and the second compression pump 9，Effect through centrifugal atomizer 5，The material of liquid is formed fine spray be injected in hothouse 4，Outside air under the effect of aerator 12 through air filter 13 and the effect of heater 11，The gas forming high temperature and high speed moves downward in hothouse 4 with spraying，Owing to spraying increases the contact area with air，High temperature air is easy to evaporate totally the moisture in material，Dried material is discharged from discharge gate 23，Air with molecule material enters in cyclone separator 17 from the side of hothouse 4，In the separation through cyclone separator 17，Fine particle thing in air is separated from air，Discharge from discharging opening 20，Remaining air turns again in cyclone separator 17 from other return pipe 18，Through secondary separation，The material particles in air is made to be totally separated out，Air then enters ventilation duct 14，Under the effect of the first compression pump 15，Change air pressure，Enter in ventilating layer 3，Owing to hothouse 4 is different with the atmospheric pressure in ventilating layer 3，Inwall 2 can produce different shapes according to the difference of both sides pressure，The pressure of the first compression pump 15 is continually changing，The shape of inwall 2 the most constantly changes，So that inwall is continuously in motion，Material particles in hothouse 4 is difficult to be attached on inwall 2，Play the effect of antiseized wall.

Air in ventilating layer 3 enters in dust removal machine 21 under the effect of air-introduced machine 22, the dust in air and the material particles that cannot separate is separated with air, is discharged in air by clean air, does not results in the pollution of air.

This utility model is compared to traditional spray dryer, it is double-deck that hothouse is divided into inner and outer wall, ventilating layer is set between the inner walls and the outer, inwall takes soft mobilizable material, by changing the pressure differential between ventilating layer and hothouse, inwall is in constantly vibration, avoid the attachment of particulate matter, and in traditional drying tower, must be equipped with gas sweeping device, and gas sweeping device is set in drying tower and easily makes particulate matter be attached on gas sweeping device, and easily have influence on dry process, and this utility model is not added with any equipment in hothouse, dry run is the most at all affected, the effect of antiseized wall can be played again.
