Abstract

The invention relates to the technical field of spray drying, in particular to a spray cooling dryer, which comprises a drying barrel. A feed inlet is arranged at the top of the drying barrel, a sprayer is arranged at the feed inlet, a high-pressure pump and a liquid feed barrel are sequentially connected to the outside of the feed inlet, a feeder is arranged at the bottom of the drying barrel, a cyclone separator, a dust collector and fan are sequentially arranged with an air outlet of the drying barrel, and an electric heater, a steam heater and an air filter are sequentially connected to an air inlet of the drying barrel. The spray cooling dryer has the advantages of high drying speed, wide application range, operational simplicity and stability and convenience in control. Due to the steam heater additionally arranged at the air inlet of the dryer, secondary heating can be performed, external air can be heated more uniformly, and drying effect of the spray cooling dryer is improved greatly.

Description

Spraying cool drying machine
Technical field
The present invention relates to the spray drying technology field, relate in particular to a kind of spraying cool drying machine.
Background technology
Spray-drying is that feed liquid (solution, emulsion, suspension or slurries) is dispersed into vaporific droplet with atomizer, makes it dry and a kind of dry run acquisition powder state product with this vaporific drop of energy heating again.Be mainly used in industries such as chemical industry, food, pharmacy, pottery, mist projection granulating, spraying cooling granulation.
The air inlet of existing drying machine generally is connected with electric heater and air cleaner in turn, and outside air forms hot gas and gets into drying after air cleaner filtration and electric heater heating.Because it is even inadequately sometimes that outside air just through once heating, heats, can influence the operating efficiency of drying machine greatly.
Summary of the invention
The technical problem that the present invention will solve is: in order to improve the operating efficiency of drying machine, address the aforementioned drawbacks, the present invention provides a kind of spraying cool drying machine.
The technical solution adopted for the present invention to solve the technical problems is: a kind of spraying cool drying machine; Comprise drying, the drying top has charging aperture, and the charging aperture place is provided with atomizer; And be circumscribed with high-pressure pump and feed liquid tube successively; The bottom of drying is provided with blanking device, and the gas outlet of drying is connected with cyclone separator, deduster and blower fan in turn, and the air inlet of described drying is connected with electric heater, steam heater and air cleaner in turn.
The invention has the beneficial effects as follows, the present invention's cool drying machine of spraying, rate of drying is fast, applied range, simple to operate stable, control is convenient.Because the air inlet of drying machine has been set up steam heater, can carry out post bake to air, make that the outside air heating is more even, thereby improved the drying efficiency of spraying cool drying machine greatly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the spray structural representation of the optimum embodiment of cool drying machine of the present invention.
Among the figure 1, drying, 2, atomizer, 3, high-pressure pump, 4, the feed liquid tube, 5, blanking device, 6, cyclone separator, 7, deduster, 8, blower fan, 9, electric heater, 10, steam heater, 11, air cleaner.
The specific embodiment
Combine accompanying drawing that the present invention is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, be the spray optimum embodiment of cool drying machine of the present invention, comprise drying 1; Drying 1 top has charging aperture; The charging aperture place is provided with atomizer 2, and is circumscribed with high-pressure pump 3 and feed liquid tube 4 successively, and the bottom of drying 1 is provided with blanking device 5; The gas outlet of drying 1 is connected with cyclone separator 6, deduster 7 and blower fan 8 in turn, and the air inlet of drying 1 is connected with electric heater 9, steam heater 10 and air cleaner 11 in turn.
Operation principle of the present invention is: outside air is after air cleaner 11 filters; Through steam heater 10, electric heater 9 preheatings, the feed liquid in the feed liquid tube 4 is through high-pressure pump 3 input dryings 1, through the vaporific drop of atomizer 2 ejections again; Then with hot-air and flow down and fall; Most of powder is collected by the blanking device 5 of drying 1 bottom, and waste gas and micro powder thereof separate through cyclone separator 6, and waste gas is discharged by blower fan 8 through deduster 7 dedustings.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
