Description
Technical field
The present invention relates to a kind of pulverizing drying equipment, belong to pulverizing, drying device field, be mainly used in coal washery the drying of coal slime, brown coal and pulverizing.
Background technology
In coal industry now, the market share of coal slime, brown coal is comparatively large, but due to its water content higher, affect its Thermogenesis, therefore price is extremely low.Although coal slime treating apparatus is commercially various informative, is all the change just on pattern after all, highly effective drying dehydration truly can not be accomplished.In the coal washery of majority, filter press and dryer are adopted mostly to the process of coal slime, filter press is the object being reached coal slime dewatering by extruding, its shortcoming is the outside dehydration that can only reach coal slime, brown coal etc., helpless for interior water, and dryer dries coal slime by introducing heat, the heat that this equipment needs is very big, easily blasts and dust atmosphere pollution, and need heat source generator, belong to backward drying device.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of compact conformation, safety, reliable, and can the pulverizing drying equipment of economize energy.
The technical scheme that the present invention adopts for its technical problem of solution is: described pulverizing drying equipment, it is characterized in that: comprise high-speed electric expreess locomotive and muffler, high-speed electric expreess locomotive is arranged on electric machine support, centrifugal high pressure fan is connected with in turn between high-speed electric expreess locomotive and muffler, fluidic generator and admission line, the top of admission line arranges feeding mouth, fluidic generator is placed on fluidic generator support, fluidic generator inside comprises compression section and extension mouth, compression section place connects admission line, extension mouth place connects centrifugal high pressure fan, admission line is arranged on admission line support.
High-speed electric expreess locomotive can be centrifugal high pressure fan and provides power; Centrifugal high pressure fan produces high pressure suction, can suck in fluidic generator by needing to pulverize dry coal slime material; Fluidic generator can be pulverized the coal slime material sucked; Muffler can weaken the noise in the course of work.
Arrange trunnion between described compression section and extension mouth, compression section, trunnion and extension mouth form jet mill district, and fluidic generator comprises the first jet mill district and the second jet mill district, arranges region of no pressure between the first jet mill district and the second jet mill district.Coal slime material can produce high-speed impact and speed-raising with high speed in the compression section in the first jet mill district, and produce high-speed jet state at trunnion place, then region of no pressure is entered through extension mouth, material after fragmentation dehydration enters in the compression section in the second jet mill district, the process of same generation high-speed impact and speed-raising, second time high-speed jet state is reached at trunnion place, whole crushing process does not need to introduce external heat source, the wind-force that the change of the pressure in whole fluidic generator and centrifugal high pressure fan produce, realize the pulverizing to coal slime material and drying, can economize energy, and use safety.Under the prerequisite that the pressure energy provided at centrifugal high pressure fan meets, also can increase the crushed zone such as the 3rd jet mill district and the 4th jet mill district.
Described fluidic generator housing arranges cleaning interface, the casing of centrifugal high pressure fan arranges magnetic valve, one end of magnetic valve connects the blade of centrifugal high pressure fan by flexible pipe, the other end connects air compressor machine.During use, cleaning interface can be connected water pump, start centrifugal high pressure fan, use water to clean fluidic generator and centrifugal high pressure fan; When the wheel backface accumulation in centrifugal high pressure fan has the coal slime of more difficult cleaning, can air compressor machine be started, open magnetic valve, use high velocity air post to clear up impeller.
Described high-speed electric expreess locomotive connects PLC control system, is connected gearbox between high-speed electric expreess locomotive with centrifugal high pressure fan.Employing PLC system controls, and can improve automaticity, increase work efficiency; There is gearbox between high-speed electric expreess locomotive and centrifugal high pressure fan, the object that centrifugal high pressure fan reaches different rotating speeds can be realized.
This equipment has good treatment effect to coal slime, brown coal etc., and single treatment can reach the dehydrating effect of coal slime 10%-15%, brown coal about 9%, and after single treatment, most of granularity can be controlled within 1000 μm.
In addition, this equipment also can add detecting instrument and realize the operating on-line checkingi of equipment.
The invention has the beneficial effects as follows:
By the setting of fluidic generator and centrifugal high pressure fan, make the whole course of work by the change of the high pressure wind-force that produces and pressure, complete the pulverizing to coal slime, brown coal material, high safety, there are not the hazards such as blast, and without the need to introducing thermal source, economize energy; The course of work of package unit controls by PLC control system, and automaticity improves, and can increase work efficiency; Have gearbox between high-speed electric expreess locomotive and centrifugal high pressure fan, can control centrifugal high pressure fan and realize different rotating speeds, when making work, according to needing, the water content of dried material is how many, selects rotating speed, makes system cloud gray model steady, can long time continuous working; The setting of muffler, effectively can reduce the noise produced when equipment runs.
