Description

A kind of wet molybdenum concentrate is dry and miberal powder collection system
Technical field
The utility model relates to a kind of wet molybdenum concentrate drying and miberal powder collection systems.
Background technique
The molybdenum concentrate obtained by flotation, although have passed through certain filtering, filters pressing, moisture content therein, kerosene contain It measures still very high.Traditional deoiling, dewatering technique be concentration-filtering-drying process, with equipment be mostly center drive concentrator, Outside filtering type drum vacuumfilter and steam helicoid screw dryer, due to the limitation of dewatering process and appointed condition, the molybdenum essence of production Dormant oil water content is higher, has balling, caking phenomenon after mixing pack, causes roasting process half-cooked, molybdenum oxide sulfur-bearing is exceeded.Tradition In operating process, feed intake, splicing, charging are manual operation, dust from flying, environmental pollution, and mineral leakage is serious.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of wet molybdenum concentrate drying and miberal powder collection system, the systems Wet molybdenum concentrate can be made to reach dehydration deoiling effect well, crush dough, improve the dispersibility of molybdenum concentrate, calcination procedure is improved and produce Product index;And the system automation degree is high, saves manpower, improves production efficiency, protects environment.
The utility model is realized in this way:
A kind of wet molybdenum concentrate it is dry and and miberal powder collection system, be characterized in that, including three drum driers, three are dry The feed inlet of dry machine is connect with screw(-type) feeder, and the feed inlet of screw(-type) feeder is connect with feed bin a, the heat of three drum drier Wind entrance and combustion chamber, the air-vent and air inlet of the combustion chamber are connected separately with air blower and natural gas air inlet pipe Road;The discharge port of three drum drier is connected with vibrating screen in turn by pipeline, bucket mentions, feed bin b, storehouse pumps and loading head, institute The material outlet for stating loading head connects feed bin c by pipeline;The upper end feed bin c is equipped with bagroom, and the powder of bagroom Material outlet is connected with the powder entrance of feed bin c by pipeline, and the dust outlet of the loading head passes through pipeline and bag collection The powder entrance of device is connected.
Further, it is equipped with air compressor in storehouse pump steam inlet, air compressor provides power, the material after making drying Feed bin c is remotely delivered to by pipeline by storehouse pump.
Further, valve is equipped on the pipeline between the powder outlet of bagroom and the powder entrance of feed bin c, In waiting bin after material sedimentation, opens valve and transfer the material in bagroom to feed bin c.
The beneficial effects of the utility model are:
Wet molybdenum concentrate enters the drying of three drum driers after being heated by screw(-type) feeder, wet molybdenum concentrate can be made to reach good It is dehydrated deoiling effect, is sent into Vibration Screen sub-material group later, improves the dispersibility of molybdenum concentrate, improves roasting technique technical indicator; System automation degree is high, it is dry after molybdenum concentrate can by struggle against mention, storehouse pumps the feeding warehouse-of automatic transportation to rotary kiln Feed bin c saves manpower, makes the equipment integration such as dry molybdenum concentrate de-oiling, screening, transport, is not necessarily to hand haulage's material, reduces Manpower improves production efficiency, and environmental-friendly, and loss of material rate is low.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: the combustion chamber 1- feed bin a, 2-, 3- air blower, 4- screw(-type) feeder, tri- drum drier of 5-, 6- vibrating screen, 7- Bucket mentions, the 8- feed bin storehouse b, 9- pump, 10- air compressor, 11- feed bin c, 12- bagroom, 13- natural gas air inlet pipe road, 14- valve, 15- loading head, 1501- dust outlet, 1502- material outlet.
Specific embodiment
As shown in Figure 1, the wet molybdenum concentrate is dry and conveys efficient joint device, including three drum driers 5, three drum driers 5 feed inlet is connect with screw(-type) feeder 4 by pipeline, and the feed inlet of screw(-type) feeder 4 is connect with feed bin a1 by pipeline, institute The hot-wind inlet for stating three drum driers 5 is connected with combustion chamber 2 by pipeline, the air-vent and air inlet point of the combustion chamber 2 It is not connected with air blower 3 and natural gas air inlet pipe road 13;Fresh air is conveyed from air blower 3 from air-vent to combustion chamber 2, by day Right gas air inlet pipeline 13 conveys natural gas to combustion chamber 2 by air inlet, and fresh air mixes combustion with natural gas by a certain percentage It burns, heat is delivered to screw(-type) feeder 4, heats to material.
The discharge port of three drum driers 5 is connected with vibrating screen 6 in turn by pipeline, bucket mentions 7, feed bin b8, storehouse pumps 9 and gathers materials The material outlet 1502 of device 15, the loading head 15 connects feed bin c11 by pipeline;The upper end feed bin c11 is equipped with bagroom 12, and the powder outlet of bagroom 12 is connected with the powder entrance 1102 of feed bin c11 by pipeline, the loading head 15 Dust outlet 1501 be connected by pipeline with the powder entrance of bagroom.Go out in the powder of the bagroom 12 Pipeline between mouth and the powder entrance of feed bin c11 is equipped with valve 14
9 air inlets are pumped in storehouse, air compressor 10 is connected by pipeline, power is provided by air compressor 10, after dry Material loading head 15 9 is delivered to through the material inlet of loading head 15 by pipeline by storehouse pump;Dust is flown upward in loading head 15 (the lesser material of particle) enters bagroom 12 through dust outlet 1501 with air, settles to material in bagroom 12 Afterwards, valve 14 is opened to transfer the material powder of the collection in bagroom 12 to feed bin c11;The biggish material of particle sinks to collection After glassware 15, the material outlet 1502 through loading head 15 is sent into storehouse c11, and the material in feed bin c11 is sent by discharge port to rotary kiln It is produced.
