Description
Technical field
The utility model relates to a kind of vacuum jet drying device, belongs to dry, field of crushing equipment.
Background technology
Dehydration equipment in the market for water-containing materials such as coal slime, mud, industrial hazard discarded objects is varied, but all can not reach highly effective drying dehydration truly.High-moisture percentage can reduce coal slime calorific value, greatly increases cost of transportation, is also unfavorable for that mud and the useless Subsequent secure of sticky wet class industry danger are disposed, and therefore, dehydrating is that coal slime utilizes and mud, danger are given up the key issue of safe disposal.Use more drying equipment to be filter press and dryer in present coal washery, filter press is that the water content of its finished product coal slime is mostly more than 20%, and dewatering efficiency is lower by dewatering to the extruding of coal slime.Dryer is dried by introducing external heat source, and energy waste is higher, easily produces blast and dust pollution.Although also have many vacuum equipments can complete oven dry crushed work at present, its structure major part is more complicated, and drying effect is poor.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of high integrated, high efficiency, safe, reliable, energy-conservation, the vacuum jet drying device of compact conformation.
Vacuum jet drying device described in the utility model, comprise drive unit, drive unit connects centrifugal high pressure fan, centrifugal high pressure fan connects wear-resistant bend, wear-resistant bend connects fluidic generator discharge end, fluidic generator is supported by support, and fluidic generator feeding end connects feed pipe, and the angle between the axis of centrifugal high pressure fan and the axis of fluidic generator is more than or equal to 90 ° and is less than 180 °.
The drying and crushing of material mainly completes in fluidic generator.Material produces with high speed and clashes into and speed-raising in fluidic generator, and produces jet state, then enters wear-resistant bend.The shock of material in fluidic generator and speed-raising produce crushing effect, and produce second time pulverize because the change of pressure produces explosive effect, and reach velocity of sound when material produces jet state hourly velocity in fluidic generator, now water is separated from material.Introduce without any external heat source in whole pulverizing dry run.Pressure change in fluidic generator and the generation of jet effect are that the wind-force produced by centrifugal high pressure fan realizes completely.It is safe and reliable that this pulverizes dry run, and energy utilization rate is higher.By practical for fluidic generator series connection, jet effect can be produced repeatedly to increase pulverizing and the degree of drying of material under the condition that power of fan meets.Angle between the axis and the axis of fluidic generator of centrifugal high pressure fan is more than or equal to the acceleration that 90 ° are more conducive to material when being less than 180 °, simultaneously can be better to the process of viscous material.
Described feed pipe is distributed with entrance, wherein an entrance joint noise reduction device, all the other are charging aperture.Feed pipe interface respectively as charging aperture and muffler interface, and can increase entry number.
Described feed pipe is arranged two entrances, comprise top entry and side entry, top entry joint noise reduction device, side entry is charging aperture.
Described drive unit comprises high-speed electric expreess locomotive, high-speed electric expreess locomotive connection for transmission case, and transmission case connects centrifugal high pressure fan, and high-speed electric expreess locomotive, transmission case, centrifugal high pressure fan are installed on fan supporter.
The casing of described centrifugal high pressure fan arranges magnetic valve, and magnetic valve one end connects the blade of centrifugal high pressure fan by flexible pipe, and the other end connects air compressor machine.Air compressor machine can be started for the material of the more difficult cleaning of wheel backface accumulation in centrifugal high pressure fan and open magnetic valve, use high velocity air to clear up impeller.
Whole system is controlled by PLC control system, and can realize automated production, and simultaneously high-speed electric expreess locomotive can be furnished with frequency converter, by the speed of Frequency Converter Control high-speed electric expreess locomotive to realize different production requirements.This equipment to coal slime, brown coal etc. have good treatment effect, single treatment can reach the dehydrating effect of coal slime 10%-15%, brown coal about 9%, within after single treatment, most of granularity can be controlled in 1000um.In addition, the configurable various kinds of sensors of this equipment is to realize the operating on-line monitoring of equipment.
The beneficial effects of the utility model are:
By the setting of fluidic generator and centrifugal high pressure fan, make the whole course of work by the change of the high pressure positive blower that produces and pressure, complete the pulverizing of the material to coal slime, brown coal., without the need to introducing thermal source, there are not the hazards such as blast in the high safety of this equipment.The course of work of package unit is controlled by PLC control system, and can realize Automated condtrol by various sensor, operating efficiency is high.Separately according to the requirement to dry materials degree, by the rotating speed of Frequency Converter Control centrifugal high pressure fan, the work of system continuous and stable can be made; And the utility model is applicable to other moisture field such as mud, industrial hazard discarded object needing drying similar.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, silencing means 2, feed pipe 3, fluidic generator 4, support 5, wear-resistant bend 6, magnetic valve 7, flexible pipe 8, centrifugal high pressure fan 9, transmission case 10, high-speed electric expreess locomotive 11, fan supporter 12, charging aperture.
