Abstract
The invention relates to drying equipment, in particular to a flash dryer. The flash dryer comprises a barrel body, wherein a feeding port is formed in the lower end of the barrel body, a discharging port is formed in the upper end of the barrel body, a fan is installed under the feeding port, the fan and the barrel body are connected through an air inlet pipe, and a heating resistor wire is installed in the air inlet pipe. A smashing device is installed in the barrel body and located under the feeding port. A particle grading device is installed at the upper end of the barrel body, the discharging port is connected with a material collecting chamber, and the material collecting chamber is connected with a dust removal chamber. The flash dryer has the advantages that wet materials enter from the feeding port and smashed by the smashing device, the fan provides hot air into the barrel body through the air inlet pipe, a strong smashing area is formed, the hot air can heat the wet materials, and the drying speed is increased. The particle grading device is installed in the barrel body, the revolution number of the particle grading device can be adjusted as needed, and therefore the fineness and water content of products are controlled.
Description
Technical field
The present invention relates to drying equipment, especially a kind of pneumatic conveyer dryer.
Background technology
Pneumatic conveying drying is a kind of continuous efficient fluidization of solid drying means.It is sent into the wet stock in pureed, granular or bulk in thermal current, with it and flow, thus obtains being dispersed into granular dry products.Dry object is moisture in some raw material of removing, semi-finished product or solvent, and with regard to chemical industry, object is to make material be convenient to packaging, transport, storage, processing and use.
Pneumatic conveyer dryer has that structure is simple, small investment, drying time are short and do not change the advantage of heat sensitive material, is therefore widely used in the industrial production.Traditional pneumatic conveyer dryer complex structure, drying effect is poor.And wet product is blown as in cutter pipeline, causes bonding, stick the inwall at drying duct, be not easy cleaning, reduce drying efficiency, also cannot ensure the quality of dried material.
Summary of the invention
The technical problem to be solved in the present invention is: overcome deficiency of the prior art, and provide a kind of drying efficiency high, wet product can not be bonded in the pneumatic conveyer dryer in drying duct.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of pneumatic conveyer dryer, comprise cylindrical shell, there is charging aperture the lower end of described cylindrical shell, and there is discharging opening the upper end of cylindrical shell, is provided with blower fan below described charging aperture, and described blower fan is connected by blast pipe with between cylindrical shell, is provided with resistive heater in described blast pipe; Be provided with reducing mechanism in described cylindrical shell, described reducing mechanism is positioned at below charging aperture; The upper end of described cylindrical shell is provided with particle grading device, and described discharging opening is connected with material collection room, and described material collection room is connected with dirt pocket.
Further, described reducing mechanism comprises grating disk and pulverizes hammer, and pulverize hammer and be fixed by screws on grating disk, grating disk is connected with turning cylinder.
Further, described particle grading device is taper Multi-vane type welded structure, and described particle grading device is connected with motor and speed changer.
Further, described particle grading device is back taper squirrel-cage.
Further, described dirt pocket is sack cleaner, and covering material selected by described cloth bag.
Employing the invention has the beneficial effects as follows: wet stock enters from charging aperture, and after reducing mechanism is pulverized, blower fan provides hot blast by blast pipe to inner barrel, form strong crushed zone on the one hand, on the other hand, hot blast heats wet stock, accelerates rate of drying.In cylindrical shell, particle grading device is installed, the revolution of particle grading device can be regulated as required, thus reach the fineness and water content that control product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, 1 is cylindrical shell, and 2 is discharging opening, and 3 is blower fan, and 4 is blast pipe, and 5 is resistive heater, and 6 is grating disk, and 7 for pulverizing hammer, and 8 is material collection room, and 9 is dirt pocket, and 10 is particle grading device, and 11 is charging aperture
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, a kind of pneumatic conveyer dryer, comprises cylindrical shell 1, there is charging aperture 11 lower end of described cylindrical shell 1, and there is discharging opening 2 upper end of cylindrical shell, is provided with blower fan 3 below described charging aperture 11, described blower fan 3 is connected by blast pipe 4 with between cylindrical shell 1, is provided with resistive heater 5 in described blast pipe 4; Be provided with reducing mechanism in described cylindrical shell 1, described reducing mechanism is positioned at below charging aperture 11; The upper end of described cylindrical shell 1 is provided with particle grading device 10, and described discharging opening 2 is connected with material collection room 8, and described material collection room 8 is connected with dirt pocket 9.
Operation principle: wet stock enters from charging aperture 11, after reducing mechanism is pulverized, blower fan 3 provides hot blast to cylindrical shell 1 inside by blast pipe 4, and form strong crushed zone on the one hand, on the other hand, hot blast heats wet stock, accelerates rate of drying.
Described reducing mechanism comprises grating disk 6 and pulverizes hammer 7, and pulverize hammer 7 and be fixed by screws on grating disk 6, grating disk 6 is connected with turning cylinder.Adopt this structure, after adding wet stock, after reducing mechanism is pulverized, then by heated-air drying, effective.
Described particle grading device 10 is taper Multi-vane type welded structure, and described particle grading device 10 is connected with motor and speed changer.Adopt this structure, the revolution of particle grading device 10 can be regulated as required, thus reach the fineness and water content that control product.
Described particle grading device 10 is in back taper squirrel-cage.Adopt this structure, grading effect is good, and efficiency is high.
Described dirt pocket 9 is sack cleaner, and covering material selected by described cloth bag.Adopt this structure, gas permeability, resistance to pressure, service life are all more satisfactory, and dust removal efficiency can reach 99.7%.
The above; be only the specific embodiment of the present invention, protection scope of the present invention is not limited thereto, and is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should define with claim is as the criterion.
