Technical field

Nickel minerals production kind equipment field is the utility model is related to, is specifically exactly matching used a kind of dry with combustion furnace Dry stove.

Background technology

, it is necessary to which extension bar carries out operation in coal drilling process, need to be attached between extension bar and extension bar, realize deep layer The exploitation of coal, in extension bar connection procedure, the connective stability between two extension bars has influence on operating efficiency and the use in later stage Life-span, connected between extension bar and extension bar it is unstable extension bar can be caused to loosen in later stage drilling process, connected between extension bar and extension bar Power is excessive, occurs extension bar phenomenon of rupture in drilling process, therefore when to ensure effective connection between extension bar be coal drilling well Important step.

China's nickel minerals type is mainly copper nickel sulfide mineral and lateritic nickel ore, with the world's economic development nineties in last century, It is quick to account for the stainless steel demand growth of nickel purposes 65%, before nickel demand 5 years it is flat it is about annual increase by more than 4%, prediction from now on 5~10 Year, growth rate 3.5% one 4%, the nickel growth rate of demand in wherein Asia will be 7%, and the whole world is about visited obtain 70,000,000 tons of nickel amounts of metal so far Resource, wherein, about 30,000,000 tons of nickel sulfide, account for 42%, remaining is Lateritic Soil nickel, develops the strong point of laterite-type nickel ore It is：Lateritic Soil nickel resources enrich, and there are 41,000,000 tons of nickel amounts of metal in the whole world, reconnoitres that cost is low, and laterite-type nickel ore mainly uses Hydrometallurgy.

Nickel minerals raw material needs to use in production to be dried, and the supporting combustion furnace of drying machine uses, and utilizes the heat of combustion furnace Wind carries out raw material drying, but the fiting effect of existing drying oven and combustion furnace is poor, and drying time length, efficiency is low to cause resource The shortcomings that wasting, and easily producing dust.

The content of the invention

The purpose of this utility model is to provide a kind of drying oven, and the drying oven can be well using remaining caused by combustion furnace Heat is dried, and drying efficiency is high, can realize continuous production, drying process does not produce dust, green.

The technical scheme in the invention for solving the technical problem is：A kind of drying oven, including drying device, company Connection device, exhaust drawing mechanism, hot air apparatus, feed arrangement, drive device, described drying device 1 are horizontally or diagonally placed, Described drying device both ends are connected by attachment means with exhaust drawing mechanism, hot air apparatus, and described feed arrangement is set At the top of hot air apparatus, described drive device driving drying device rotates, and described drive device is by motor and drive gear Composition.

As optimization, described drying device is made up of drying tube, drying tube gear, blade, described drying tube appearance Face, which is provided with drying tube gear inner surface setting, inclined blade, and drying device is transported raw material by the blade that is rotatably assorted It is defeated.

As optimization, described blade, which often encloses, is uniformly distributed individual, often 30 ° of circle blade relative rotation, positioned at dry tube end Described blade have one side with dry end surfaces in the same plane, blade can not only transport raw material, moreover it is possible to by raw material kick up into Row fully drying.

As optimization, described exhaust drawing mechanism includes discharging opening, side plate, filter, blast pipe, exhaust discharge nozzle Body, described exhaust discharging its bottom are provided with discharging opening, filter, described exhaust are provided with described blast pipe Discharging body is connected with inclined side plate, and the filter at top can Chalk-dust filtering well.

As optimization, described filter discharges body left side in the same plane with exhaust, when exhaust discharging dress Put when being connected with drying device, the rotation of blade can strike off the dust on filter surface.

As optimization, described hot air apparatus includes hot blast body, blast pipe, swash plate, described hot blast body right side With blast pipe right side in the same plane, swash plate is connected with the left of described hot blast body, the design of warm-air pipe makes raw material not Warm-air pipe can be entered.

As optimization, described feed arrangement includes feed hopper, storage bin hopper, rotary body, and described feed hopper is connected to pipe On shape storage bin hopper, rotary body is provided with described storage bin hopper, the plate body that described rotary body is 120 ° by three angles forms, Described plate body length is less than storage bin hopper radius, and warm-air pipe blows air into drying device by blower fan, because plate body does not contact Dust caused by filler is drawn onto in drying tube by storage bin hopper, negative pressure caused by the feed arrangement, while is also avoided that a large amount of Gas enter drying tube influence drying efficiency.

The beneficial effects of the utility model are：Compared with prior art, a kind of drying oven of the present utility model, passes through outside Drive drying device to rotate, service life of equipment length, raw material is kicked up by transport of blades, by combustion furnace waste heat dry feedstock, Energy-conserving and environment-protective, it is green by filter Chalk-dust filtering, dust is inhaled by the setting of feed arrangement.
