Description
Technical field
The utility model relates to the device of the easy comminuting matter drying of solid, and specifically, it is a kind of pneumatic conveying drying and cylinder combination drying device of mud.
Background technology
Municipal sewage treatment is built up in each city, the whole nation and is put into operation; this has played positive role to the water pollution problems that prevents China; but the mud that forms in the sewage disposal process has brought environmental pollution again; therefore aspect the protection environment, the processing of municipal sludge is become a problem of needing solution badly again.The method of disposal of mud mainly contains soil utilization, landfill, burning, biochemical treatment and topples over and throw sea etc. at present.But the moisture percentage in sewage sludge height that in sewage disposal process, is produced, volume is big, and this brings great inconvenience for its transportation, final disposal and utilization, therefore must utilize the means of sludge dewatering, drying, and moisture is separated from mud.Practice both domestic and external shows, after traditional concentrated and shrink PROCESS FOR TREATMENT, the moisture content of mud is difficult to reach below 70%, and economic mechanical dehydration moisture content of the cake also is about 75%, this moment, the calorific value of mud was very low, also needed very big energy expenditure if adopt the means of burning to handle.So reach the deep dehydration of mud, comparatively Jing Ji method is exactly to use heated drying technology and equipment commonly used in the chemical industry operation.
The airflow drying tube of mud and roller drying have all obtained actual application at present, as Chinese utility model patent " drum-type sludge drier ", its application number is 99250619.0, notification number is CN2402986, but this drum-type sludge drier has its defective, drum dryer dry run mud lumps easily, and the drying tube length that airflow drying tube reaches necessarily required drying effect needs is longer.Therefore how to solve drum dryer easily caking and the long problem of pneumatic conveying drying length of tube simultaneously, become problem demanding prompt solution.
The utility model content
It is good that technical problem to be solved in the utility model provides a kind of drying effect, drying sludge evenly, do not lump, volume is little and the pneumatic conveying drying of mud and cylinder combination drying device with energy efficient function.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
The pneumatic conveying drying of mud of the present utility model and cylinder combination drying device, this device is made up of airflow drying tube and drum dryer, it is characterized in that: on described airflow drying tube, have hot-wind inlet and delivery outlet, between the hot-wind inlet of described airflow drying tube, delivery outlet, have charging aperture, between described charging aperture and delivery outlet, be provided with the beater that is used for broken mud, drum dryer one end is communicated with airflow drying tube by the delivery outlet of airflow drying tube, and its other end is provided with the dewatered sludge outlet.
On described airflow drying tube, be equipped with and be used to prevent the separator tube that stops up.
Owing to adopted said structure, at first, wet mud is by behind the airflow drying tube preliminarily dried, the water content of wet mud is reduced, thereby make the mud prevented from caking that enters drum dryer, drum dryer can remedy the dry halfway situation of airflow drying tube, so the utility model has guaranteed to be issued in the condition that shortens the pneumatic conveying drying length of tube Expected Results of drying sludge, so the utility model can shorten the length of airflow drying tube under same drying effect, also avoided simultaneously the roller drying pipe shortcoming of caking easily, therefore the utility model has solved effectively and has occurred caking and the long problem of pneumatic conveying drying drying tube length in traditional drying sludge process easily, thereby guaranteed the serialization of industrial process, the tranquilization operation, it is little to the utlity model has volume in addition, be fit to advantages such as mobile, its energy utilization is abundant, drying effect is good, has also satisfied environmental protection requirement simultaneously.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the pneumatic conveying drying of the utility model mud and the schematic diagram of cylinder combination drying device.
The specific embodiment
As shown in Figure 1, it is the pneumatic conveying drying of the utility model mud and the schematic diagram of cylinder combination drying device.A kind of pneumatic conveying drying of mud and cylinder combination drying device, this device is made up of airflow drying tube 7 and drum dryer 10.On described airflow drying tube 7, have hot-wind inlet 2 and delivery outlet 9, be connected to hot-blast stove 1 on the hot-wind inlet 2, hot-wind inlet 2 at described airflow drying tube 7, have charging aperture 5 between the delivery outlet 9, on charging aperture 5 next doors belt conveyor 4 and mud hopper 3 are installed, wherein mud is delivered on the belt conveyor 4 by mud hopper 3, belt conveyor 4 is sent into mud in the airflow drying tube 7 by charging aperture 5 more then, between this charging aperture 5 and delivery outlet 9, be provided with the beater 6 that is used for broken mud, on described airflow drying tube 7 separator tube 8 is installed, this separator tube 8 is used to prevent that the dry run obstruction from causing the accident; Drum dryer 10 1 ends are communicated with airflow drying tube 7 by the delivery outlet 9 of airflow drying tube 7, and its other end is provided with dewatered sludge outlet 12, and this dewatered sludge outlet 12 is communicated with gas-solid separating device 12.
When the utility model uses, mud enters airflow drying tube 7 by belt conveyor 4 by charging aperture 5 from mud hopper 3, the hot-air that hot-blast stove 1 produces is also sent into airflow drying tube 7 simultaneously, carry on granule mud top toward airflow drying tube 7 under the effect of hot blast, bulky grain mud drops to beater 6 in the gravity effect, broken under the effect of beater 6, the top of past airflow drying tube 7 conveying again under the effect of hot blast of broken good mud.Separator tube 8 is housed on airflow drying tube 7, it is used to prevent that the dry run obstruction from causing the accident, the mud that comes out from airflow drying tube 7 enters drum dryer 10, mud obtains further drying in drum dryer 10, reach the effect of required drying, wherein the mud of the water yield that contains 50-80% that enters by charging aperture 5 through the utility model drying after, the water content that makes mud is below 10%, so can deliver to gas-solid separating device 12 from the dewatered sludge that drum dryer 10 comes out, the mud after the separation just becomes dried sludge product.The technical program is owing to adopted the structure of airflow drying tube 7 and drum dryer 10 work in combination, so mud is difficult to caking in dry run, and can shorten the length that reaches the drying tube of same drying effect when using airflow drying tube 7 merely, on this external airflow drying tube 7 separator tube 8 is installed, it can guarantee this continuous even running of the present utility model.
In a word,, should illustrate that obviously those skilled in the art can carry out various variations and remodeling though the utility model has been enumerated above-mentioned preferred implementation.Therefore, unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included within the protection domain of the present utility model.
