Abstract
The utility model provides a pressure type spraying drier, comprising a drying column, a sirocco distributor mechanism and an atomiser, the sirocco distributor mechanism is arranged on the top of the drying column, the atomiser is arranged on the feed liquid ingress of the drying column, the atomiser comprises a nozzle boss, a nozzle, a spray core, a spray piece, a vane and a stuffiness piece, the nozzle is arranged on the nozzle boss, and the spray core, the stuffiness piece, the vane and the spray piece are arranged on the nozzle in turn. The utility model speeds up the drying rate of the feed liquid though arrangement of the atomiser, the temperature of the liquid drop is low in the process of drying, the drying quality of the products is better, so the products have favorable dispersiveness, fluidness, dissolvability, simple use, easy operation, adapting for the mass production.
Description
(1) technical field
The utility model relates to and is used for spray-dired equipment, belongs to the drying machine technical field.
(2) background technology
Liquid material is dried to flowable, as to have certain particle size low-density powder product with spray dryer usually, spray-dired basic principle is that the liquid material atomizing is desired granularity and size distribution, contact with high temperature unsaturation gas, drop by gas carry secretly, dry and be transported to the product gathering-device.The volume of spray dryer will make droplet have the sufficiently long holdup time, even maximum droplet also can be dried to desired final moisture content.Therefore the volume of spray dryer is often very big, and its material saturation is low, the power consumption height, and investment is big, makes energy utilization rate low because of a large amount of dry air of need sometimes.For high tonnage operation, need with expensive turn up 40, the rotating disk sprayer of 000rpm, this just means high power consumption and easy to wear.Develop slow-speed of revolution sprayer at present and remedying these shortcomings.Spray dryer reduces pressure operation sometimes so that improve rate of drying under cryogenic conditions, to handle high-thermosensitive material.
Aspect large-tonnage spray-drying, the most significant development is the employing of multilevel drying.Wherein the first order is a spray-drying output moderate amount of moisture product, it is sent into very little fluid bed or Vibratingfluidbeddrier again, takes off inner moisture so that obtain the long time of staying.The second level or the third level can be belt or percolation circulation dryer.It is original 30%～50% that this method can make the volume of spray dryer be reduced to, the corresponding drying cost that also reduced.The second level or the third level can be used for product " instant processing ", condense the rehydration and the dissolubility of promoting product by control.Therefore this technology is considered to a mature technique usually.But leeway still is significantly improved at aspects such as production efficiency and dry mass (particle size distribution uniformity, reduce or eliminate wall sticking phenomenon).
(3) summary of the invention
The utility model provides a kind of rate of drying fast, easy to operate at the deficiencies in the prior art, is suitable for large-scale production, the better pressure spray dryer of dry mass.
The technical solution adopted in the utility model is:
Pressure spray dryer is made up of drying tower, hot-air distributor and sprayer, and hot-air distributor is installed in the drying tower top, and sprayer is installed in the feed liquid porch on the drying tower.
Sprayer is made up of nozzle boss, nozzle, spray core, spray sheet, blade and vexed, and nozzle is installed on the nozzle boss, and spray core, vexed, blade and spray sheet are installed in the nozzle successively.
Be provided with the shaped form bend in the blade of sprayer.
The utility model accelerates the feed liquid rate of drying by sprayer is set, the temperature of drop is not high in the dry run, and the product drying quality is better, can make product have good dispersiveness, flowability and dissolubility, use simply, easy to operate, be suitable for large-scale production.

(5) specific embodiment
Fig. 1 has provided the structural representation of the utility model pressure spray dryer.Be made up of drying tower 1, hot-air distributor 2 and sprayer 3, hot-air distributor 2 is installed in drying tower 1 top, and sprayer 3 is installed in the feed liquid porch on the drying tower 1.Feed liquid is dried in drying tower 1, and in drying tower 1, sprayer 3 is atomized into droplet with feed liquid and fully contacts with hot blast in drying tower 1 hot blast air devider 2 with hot blast cloth, carries out the caloic exchange.
Fig. 2 has provided the structure chart of sprayer 3.The effect of sprayer 3 is that feed liquid is changed into vaporific drop, with the contact area of increase with hot blast, is made up of nozzle boss 4, nozzle 5, spray core 6, spray sheet 7, blade 8 and vexed 9, nozzle 5 is installed on the nozzle boss 4, spray core 6, vexed 9, blade 8 and spray sheet 7 and be installed in successively in the nozzle 5.Feed liquid enters sprayer 3, pass through the spray core 6 of sprayer then, shape flows into blade 8 in the shape of a spiral under vexed 9 guide effect, produce centrifugal action, rotation direction spray sheet 7, the shape with the hollow cone body sprays in the drying tower 1 from nozzle 5 then, realizes spraying, thereby contact with hot blast with bigger surface area, carry out sufficient caloic exchange.Fig. 3 has provided the structure chart of blade 8, is a complex-shaped special construction, and feed liquid produces centrifugal action by its shaped form bend, rotation is flowed out, change its thickness and can obtain different feed liquid flow velocitys, thereby can change the size of droplet, obtain different product granularities.Sprayer 3 is simple in structure, noiseless during operation, and the internal structure of change nozzle can obtain needed spray shapes.
Claims (3)
1. a pressure spray dryer is made up of drying tower, hot-air distributor and sprayer, it is characterized in that: hot-air distributor is installed in the drying tower top, and sprayer is installed in the feed liquid porch on the drying tower.
2. pressure spray dryer according to claim 1, it is characterized in that: described sprayer is made up of nozzle boss, nozzle, spray core, spray sheet, blade and vexed, nozzle is installed on the nozzle boss, and spray core, vexed, blade and spray sheet are installed in the nozzle successively.
