Description

Xun Huan clean moulded coal drying machine in a kind of

Technical field

The utility model is related to clean moulded coals to dry field, is specifically Xun Huan clean moulded coal drying machine in a kind of.

Background technology

Filter Tuber For Clean Coal is uniformly mixed together with dry powder or liquid additive by coke powder or anchracite duff, using forming machine by its Flat ball type shape coal is made, because " wet bulb " intensity is low, flexible type crushes, it is therefore desirable to just have its moisture control within 3% Received shipment is defeated, preserves, the requirement of burning, so the drying of clean moulded coal becomes one of crucial process.

Existing drying machine includes several parts such as distributing device, preheating cavity, drying chamber, cooling chamber and forms, by cloth in drying chamber The air passage composition that air holes plate surrounds, after " wet bulb " enters drying chamber, slowly moves down, hot wind and material under gravity The way of contact using multistage guide plate mode, existing drying machine has the following problems in use：1st, solid accumulation angle and stove The gap that inner guide plate is formed can all make cloth wind uneven, cause hot wind insufficient contact with material, drying effect is poor；2nd, moulded coal is dry Slowly moved down with coal briquette during dry, coal briquette and stove inner wall, phase mutual friction between coal briquette and generate substantial amounts of fine dust, dust External environment is polluted from furnace roof spilling with the rising of flue gas, in vollyball, dust can together be discharged with coal briquette so that Production site flue dust diffuses, on the one hand these dust have an impact production environment, and the substantial amounts of coal dust of another aspect is in air Floating also has the hidden danger of coal-dust explosion；3rd, there are contradictions between drying efficiency and safety in production：Using low temperature Wind Volume（Dry wind Generally 90 DEG C ~ 100 DEG C of temperature）Mode drying efficiency is relatively low, if improving dry wind-warm syndrome, coal briquette can catch fire in stove pacifies Full accident.

The content of the invention

The purpose of this utility model is exactly poor in order to solve existing drying machine drying effect, and dust emission pollutes environment and has Security risk, there are the problems such as contradiction, provide Xun Huan clean moulded coal drying machine in one kind between drying efficiency and safety in production.

The concrete scheme of the utility model is：Xun Huan clean moulded coal drying machine in a kind of, there are one sides for the drying machine tool Shape shell, the enclosure left and right sides are arranged with several mutually independent drying chambers, one are formed between two row drying chambers Perforative passageway is equipped with enterprising air passage in the passageway successively along overall length from top to bottom, middle air -return duct, lower air inlet duct, it is described on Air inlet duct, middle air -return duct, lower air inlet duct are designed with a point air holes with the one side that each drying chamber contacts, and drying chamber divides wind by described Hole is communicated with air passage；Distributing trough is equipped with along overall length at the top of drying machine, corresponding each drying chamber is designed with deflector chute below distributing trough, It is equipped with to collect the upper dust gathering arrester for discharging flue gas at the top of drying chamber below deflector chute；Dry motor spindle is located at dress below drying chamber There is a discharge bucket being connected with drying chamber, equipped with discharger below each discharge bucket, equipped with sieving plate below discharger, under sieving plate For side's connection equipped with demarcation strip, demarcation strip lower section is equipped with belt conveyer, is located in passageway below discharge bucket and edge is gone back above sieving plate Overall length is equipped with next part dust hood, and dry motor spindle is equipped with supporting rack.

Enterprising air passage described in the utility model and/or lower air inlet duct are to be divided into drying machine both sides in by a total air passage Between three air passages form.

Discharge bucket and discharger described in the utility model are flexible sealing structure.

It is additionally provided with to detect the level detector of material position in drying chamber at the top of drying chamber described in the utility model.

Operation principle：Wet molding materials are sent into the distributing trough at the top of the utility model by conveyer, pass through deflector chute It is evenly dispersed in each drying chamber, is unloaded after material is covered with entire drying chamber by controlling below the utility model discharge bucket The withdrawal rate of glassware makes material slowly move down under gravity, is sent quenched good flue gas simultaneously by wind turbine Enter in enterprising air passage and lower air inlet duct, flue gas is by dividing air holes to enter each drying chamber；Enterprising air passage and lower air inlet duct flue gas temperature Degree and flow can be adjusted, and by the temperature and flow that adjust flue gas the material in drying chamber be made to be divided into rapid draing and slow Dry two processes of rapid-curing cutback：Part more than wherein enterprising air passage is flash drying process, and flue gas flow direction herein is from upper air inlet Road flows up after entering drying chamber, and last flue gas is discharged by upper dust gathering arrester；Part between lower air inlet duct and enterprising air passage For drying process at a slow speed, flue gas flow direction herein is flowed up after entering drying chamber from lower air inlet duct, then passes through middle return air It is handled after road discharge by air distribution heating system and again acts as dry flue gas into upper and lower air inlet duct；Drying is completed by drying chamber Material afterwards includes powder and molding materials, is sent into sieving plate screening by the discharger below discharge bucket, molding materials are from screening It is fallen on above plate among demarcation strip, powder falls on demarcation strip both sides below sieving plate, so that molding materials fall into conveying skin On the inside of band machine, powder is fallen on the outside of belt conveyer, and the flue gas containing powder is discharged under suction function by next part dust hood, on The ash-laden gas that dust gathering arrester is discharged with next part dust hood is collected and drains after treatment or recycle.

The utility model has the advantages that：1st, the utility model is led to flue gas using interior air passage bilateral cloth wind mode It crosses cloth wind structure to come into full contact with material, drying effect is good；2nd, material is carried out by air -return duct in setting and lower air inlet duct slow Rapid-curing cutback is dry, and by material evenly drying, the heat for avoiding existing drying machine is damaged, improves molding materials yield rate；3rd, middle return air is passed through Road is participated in road flue gas recirculation again after the low humidity flue gas of dryer section at a slow speed is extracted out by handling, and has been saved the energy, has been reduced Flue gas oxygen content improves security；4th, the utility model is utilized and had by the low temperature wind of next part dust hood to the material of discharge The function of cooling down and gather dust；5th, by setting sieving plate and powder and molding materials are separated when demarcation strip makes discharging, avoid existing Environmental pollution is individually sieved after having drying machine discharge.
