Description

A kind of spray dryer
Technical field
The utility model relates to drying machine technical field, especially a kind of spray dryer.
Background technology
Spraying dry is atomized by liquid stock solution, warp and hot blast exchange drying and form the program of powder granular products, its stoste mat high speed rotating plate or pressure nozzle in spray dryer are atomized and enter in thermal current, this drop moisture in hot blast evaporates rapidly, leave dry solid powder/particle, then be separated by air-flow.Be applicable to generate powdery, granular solid product from solution, emulsion, suspended emulsion and liquid/paste raw material.Therefore, when the particle size distribution of finished product, residual moisture content, bulk density and grain shape meet accurate standard, spraying dry is one very good technique.
CN202070178U discloses a kind of spray cooling drying machine, comprise drying, drying top has charging aperture, charging aperture place is provided with atomizer, and be circumscribed with high-pressure pump and feed liquid cylinder 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.Solve outside air only once to heat, heat uneven, affect the technical deficiency of the operating efficiency of drying machine, but also there is following problem: baking temperature is high, material is sticky wall easily, and atomizing effect is poor, ineffective technical deficiency.
Summary of the invention
The technical problems to be solved in the utility model is: overcome deficiency of the prior art, and provide a kind of drying efficiency high, material can not glue the spray dryer of wall.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of spray dryer, comprise the support of drying and support drying, atomizer is arranged at described drying top, and described atomizer is connected with material delivery system by pipeline, the bottom of described drying has air inlet, and described air inlet is connected with hot air supply device by intake stack; Be provided with the heat-resisting backgauge cloth of a circle in described drying, described heat-resisting backgauge cloth is connected by fixed bar with between drying, and there is an annulus on the top of described fixed bar, and described annulus is connected with material scraper, and described material scraper moves up and down along heat-resisting backgauge cloth; The bottom of described drying has discharging opening.
Further, in described intake stack, Electrothermal ring is installed.
Further, described discharging opening is connected with cyclone separator and sack cleaner in turn by pipeline.
Further, a circle thermal insulation clamp jacket layer is had outside described drying.
Further, between described intake stack and hot air supply device, air cleaner is installed.
Further, described material scraper is the scraper of a ring-type, and the width of described scraper is 1-1.5cm.
The beneficial effect of employing the technical solution of the utility model is: structure is simple, reasonable in design, the a part of material on heat-resisting backgauge cloth is bonded in dry run, under the movement of material scraper, the solid particle be bonded on heat-resisting backgauge cloth is scraped, the material completing drying process is discharged from the discharging opening bottom drying, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1 is drying, 2 is support, and 3 is atomizer, and 4 is intake stack, and 5 is hot air supply device, and 6 is air cleaner, and 7 is annulus, and 8 is scraper, and 9 is Electrothermal ring, and 10 is discharging opening, and 11 is cyclone separator, and 12 is sack cleaner, and 13 is heat-resisting backgauge cloth
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, a kind of spray dryer, comprise the support 2 of drying 1 and support drying, atomizer 3 is arranged at described drying top, described atomizer 3 is connected with material delivery system by pipeline, the bottom of described drying 1 has air inlet, and described air inlet is connected with hot air supply device 5 by intake stack 4; The heat-resisting backgauge cloth 13 of one circle is installed in described drying 1, described heat-resisting backgauge cloth 13 is connected by fixed bar with between drying 1, there is an annulus 7 on the top of described fixed bar, and described annulus 7 is connected with material scraper, and described material scraper moves up and down along heat-resisting backgauge cloth 13; The bottom of described drying 1 has discharging opening 10.
Operation principle: material to be dried is entered in drying 1 by atomizer 3, sprays from top to bottom, hot blast is up walked from the bottom of drying 1, and hot blast contacts with through being atomized the material to be dried processed, and carries out drying process to it; The heat-resisting backgauge cloth 13 of a circle is had in described drying 1, material is in the process of drying, a part can be bonded on heat-resisting backgauge cloth 13, then, under the movement of material scraper, scraped by the solid particle be bonded on heat-resisting backgauge cloth 13, the material completing drying process is discharged from the discharging opening 10 bottom drying 1.
In described intake stack 4, Electrothermal ring 9 is installed.Adopt this structure, again can heat air, guarantee that the temperature of hot blast is temperature required.
Described discharging opening 10 is connected with cyclone separator 11 and sack cleaner 12 in turn by pipeline.
A circle thermal insulation clamp jacket layer is had outside described drying 1.Adopt this structure, certain insulation effect can be played to the environment in drying 1, improve the utilization rate of hot-air, reduce drying cost.
Between described intake stack 4 and hot air supply device 5, air cleaner 6 is installed.Adopt this structure, filtration treatment can be carried out to the hot blast passed in drying 1, in order to avoid impurity in air or the drying of other compositions to material impacts, guarantee that dry environment is clean.
Described material scraper is the scraper 8 of a ring-type, and the width of described scraper 8 is 1-1.5cm.Adopt this structure, can be dry, while scraped by the solid material be bonded on heat-resisting backgauge cloth 13, thus avoid material to be bonded on drying 1 inwall, be difficult to cleaning; Also likely cause material cross influence.
The above; be only detailed description of the invention of the present utility model; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should define with claim is as the criterion.
