Description

A kind of coal charge conveying dryer structure
Technical field
The utility model relates to ceramic machinery technical field, more particularly to a kind of coal charge conveying dryer structure.
Background technology
Existing ceramic hot-blast furnace uses ground coal charge, is burnt again after being ground into coal dust, its high combustion efficiency, fuel availability Height, the purpose of energy-conservation can be played, but the moisture of south coal is left in 10-11% in 11-12% or so, the moisture of north coal The right side, after coal charge is ground into powder, if the moisture in coal charge is too high, the easy slagging of coal dust, block pipeline, fault rate compared with Height, investigate trouble, affect the efficiency of production.
The content of the invention
In order to solve prior art problem, the utility model provides a kind of coal charge conveying dryer structure, reduces the water of coal charge Divide content, environmental protection, ensure production efficiency.
To achieve the above object, technical scheme provided by the utility model is:A kind of coal charge conveying dryer structure, including There is conveyer belt, the conveying end of tape is connected to coal bunker, and the coal bunker is connected to spiral screw rod machine by hopper, and its feature exists In:Covered above the conveyer belt provided with a fan housing, the fan housing is respectively equipped with air inlet and air outlet, outside the conveyer belt Side is additionally provided with a protection canopy and covered, and the fan housing is located in the protection canopy, and the protection canopy bottom is provided with more coal ash Collecting pipe is used to collect coal ash, and the outer wall of the spiral screw rod machine is provided with heater.
Preferably, a homogenating plate is additionally provided with the fan housing, on the homogenating plate along its length compartment of terrain be provided with it is multiple Through hole is used for air-out.
Preferably, the heater controls its temperature by temperature controller.
Preferably, the weight that electronic scale is used to measure coal charge is provided with the hopper.
The utility model has the advantages that:
The utility model is easy to be passed through hot blast, to dry coal charge, can to subtract using increasing fan housing on the conveyor belt The water content of few coal charge, also is provided with heater on spiral screw rod machine outer wall in addition, further carries out heating, drying to coal charge, makes Either southern coal or northern coal are obtained, can be carried out being burnt after being ground into coal dust, coal charge is not easy slagging with blocking Pipeline.Fan housing can prevent coal dust from floaing everywhere to spread, and fan housing periphery is additionally provided with protection canopy so that conveyer belt is closed with other equipment Separate so that coal ash does not fly out protection canopy, and protection canopy lower end is provided with coal ash collecting pipe by coal ash collecting.It is provided with other fan housing equal Aerofoil, hot blast can be equably blown in the upper surface of conveyer belt, so as to be dried to coal charge, the utility model drying efficiency Height, good drying effect.
Brief description of the drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is the structural representation of fan housing 2 of the present utility model;
Fig. 3 is the structural representation of homogenating plate 23 of the present utility model;
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model will be further described:
Referring to figs. 1 to Fig. 3, a kind of coal charge conveying dryer structure includes conveyer belt 1, and the end of conveyer belt 1 is connected to Coal bunker 7, the coal bunker 7 is connected to spiral screw rod machine 5 by hopper 4, here in order to improve feeding efficiency, can set up Duo Tai The feeding of spiral screw rod machine 5, the weight that electronic scale is used to measure coal charge is each provided with the hopper 4.The top of conveyer belt 1 Covered provided with a fan housing 2, the fan housing 2 is respectively equipped with air inlet 21 and air outlet 22, and hot blast enters from air inlet 21, from going out Air port comes out, and here in order to make hot blast uniform, can be provided with a homogenating plate 23 in the fan housing 2, the homogenating plate 23 is located at institute State between air inlet 21 and air outlet 22, compartment of terrain is used to provided with multiple through hole 23a along its length on the homogenating plate 23 Wind, multiple through hole 23a face the upper surface of conveyer belt 1, for drying coal charge.The outside of conveyer belt 1 is additionally provided with a protection Canopy 3 is covered, the sealed set of protection canopy 3, and the fan housing 2 is located in the protection canopy 3, and the bottom of protection canopy 3 is set There are more coal ash collecting pipes 31 to be used to collect coal ash, the outer wall of the spiral screw rod machine 5 is provided with heater 6, and the heater 6 is logical Cross temperature control instrument control system its temperature.
During utility model works:Conveyer belt 1 transports coal charge, and hot blast enters from air inlet 21, is homogenized by homogenating plate 23 After-blow is dried, hot blast comes out from air outlet 22 again, the coal dust quilt outside the fan housing 2 to the upper surface of conveyer belt 1 to coal charge Protection canopy 3 is covered, and coal dust is collected by coal ash collecting pipe 31 reuses again, and spiral screw rod machine 5 is additionally provided with and added Hot device 6 carries out heating, drying to coal charge, further reduces the moisture in coal so that when coal charge carries out the process of next grinding again, It is not easy to block pipeline.
The utility model examples of implementation described above are only the preferred embodiment of the utility model, not limit this with this The practical range of utility model, therefore the change that all shape, principles according to the utility model are made, all should cover in the utility model Protection domain in.
