Further, the turnbarrel is fixed on inside drying by fixed mount.
Further, scraper is provided with inside the drying, the scraper includes fix bar and material scraping plate, institute State fix bar to be connected with drying inwall, the material scraping plate is connected parallel to the turnbarrel inwall and with the fix bar.
Further, the humidity-discharging device includes wet-emitting blower and some dehumidification tubes being connected with the wet-emitting blower Road, the wet-emitting blower be located at the drying outside, the dehumidifying pipelines be located at the turnbarrel inside and drying with Between turnbarrel.
Further, the turnbarrel bottom is higher than the drying bottom.
Further, the microwave generator is uniformly distributed in turnbarrel, and the microwave generator is respectively connected with Automatic current overload protection arrangement.
Beneficial effects of the present invention:Calcium carbonate drying device of the present invention is directly dried to calcium carbonate slurry, Eliminate the preprocessing process such as dehydration cake of press, extruding pelletization in traditional calcium carbonate drying technology, have the advantages that it is energy-efficient, And homogeneous heating, effectively increase the quality of calcium carbonate finished product.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to institute in embodiment The accompanying drawing for needing to use is briefly described, it should be apparent that, drawings in the following description are only some implementations of the invention Example, for those of ordinary skill in the art, on the premise of not paying creative work, can also obtain according to these accompanying drawings Obtain other accompanying drawings.
Fig. 1 is the structural representation of calcium carbonate drying device described according to embodiments of the present invention;
In figure:1st, feed device;2nd, high-pressure slurry flusher;3rd, drying;4th, turnbarrel;5th, rotating driving device;6、 Microwave generator;7th, high-pressure nozzle;8th, discharging opening;9th, fixed mount;10th, fix bar;11st, material scraping plate;12nd, wet-emitting blower;13rd, arrange Wet pipeline.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on Embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained belongs to present invention protection Scope.
As shown in figure 1, a kind of calcium carbonate drying device, including feed device 1, high-pressure slurry flusher 2, humidity-discharging device With drying 3, perpendicular to ground, inside is provided with a turnbarrel 4, the connection rotation driving of the turnbarrel 4 to the drying 3 Some microwave generators 6 are set in device 5, the turnbarrel 4, the upper end of the drying 3 connects the high-pressure slurry sprinkling Device 2, the high-pressure slurry flusher 2 connects the feed device 1, and the high-pressure slurry flusher 2 includes high pressure spray First 7, the high-pressure nozzle 7 is located at the upper end of the turnbarrel 4, and the bottom of the drying 3 is provided with discharging opening 8.
Further, the turnbarrel 4 is fixed on inside drying 3 by fixed mount 9.
Further, scraper is provided with inside the drying 3, the scraper includes fix bar 10 and material scraping plate 11, the fix bar 10 and the inwall of drying 3 are connected, the material scraping plate 11 parallel to the inwall of the turnbarrel 4 and with it is described Fix bar 10 is connected.
Further, the humidity-discharging device includes wet-emitting blower 12 and some hydrofuges being connected with the wet-emitting blower 12 Pipeline 13, the wet-emitting blower 12 is located at outside the drying 3, and the dehumidifying pipelines 13 are located inside the turnbarrel 4 And between drying 3 and turnbarrel 4.
