Novel drying unit
Technical field
The utility model relates to the drying unit that is used to dry carborundum, is more particularly to novel drying unit, belongs to the apparatus field of drying carborundum.
Background technology
In commercial production and life, need oven dry carborundum.Carborundum uses the hollow blade drying machine drying, and a hollow blade dryer can not reach drying requirement in the practice, generally two hollow blade dryer series connection is used.The device of present existing oven dry carborundum is that two hollow blade dryer series connection are used; Fig. 2 is the structural representation of the device of present existing oven dry carborundum.The structure of the device of present existing oven dry carborundum is: be made up of with following dryer 2 last dryer 1; Last dryer 1 comprises the oven dry body, go up drive motors 3, go up charging aperture 4 holds concurrently and goes up air inlets 4, top discharge mouth 6, top discharge pipe 7, goes up air outlet 5; Oven dry body, following drive motors 10, following charging aperture 8, following air inlet 11, lower discharge port 13, following air outlet 12, bottom discharge pipe 14 under following dryer 2 comprises; The top discharge mouth 6 of last dryer 1 is connected with the following charging aperture 8 of following dryer 2 through top discharge pipe 7; On top discharge pipe 7, be provided with top discharge Blowing stopper 9, on bottom discharge pipe 14, be provided with bottom discharge Blowing stopper 15.When using single drying machine drying carborundum; After being evaporated, water in the material accumulates in the dryer of material top; Dry air gets into from the charging aperture or the air inlet of dryer one end, extracts out from the air outlet of the other end, takes the water that material is evaporated out of dryer in the lump; Discharging Blowing stopper on the discharge nozzle can be emitted the material of dryer discharging opening and prevented that simultaneously dry air from getting into dryer from discharging opening; If do not have the discharging Blowing stopper on the discharge nozzle, have air in the time of the dryer discharging and get into from discharging opening, directly discharge again from air outlet, can not the steam in the dryer be taken out of.So, in the time will going up dryer and following dryer series connection use, also need on top discharge pipe 7, be provided with top discharge Blowing stopper 9, on bottom discharge pipe 14, be provided with bottom discharge Blowing stopper 15; But during series connection, last dryer 1 discharging carborundum moisture content is 1 ~ 5%, again by dryer 2 oven dry back dischargings down; The carborundum moisture content was at 1 ~ 5% o'clock, and the top discharge Blowing stopper 9 of last dryer 1 stops up 7 with the top discharge pipe through regular meeting.
The utility model content
The purpose of the utility model is to overcome above deficiency, and a kind of novel drying unit is provided, and it prevents that the dryer discharge nozzle from stopping up.
A kind of novel drying unit comprises dryer and following dryer, and the top discharge mouth of last dryer is connected with the following charging aperture of following dryer through the top discharge pipe of last dryer; Be fixed with deep bead on the upper wall in the housing of last dryer, last deep bead is on top discharge mouth and the last dryer between the air outlet; Be fixed with deep bead down on the upper wall in the housing that descends dryer, following deep bead is between the following charging aperture of following air inlet that descends dryer and following dryer.
The beneficial effect of the utility model is:
Because: a kind of novel drying unit, comprise dryer and following dryer, the top discharge mouth of last dryer is connected with the following charging aperture of following dryer through the top discharge pipe of last dryer; Thereby on the top discharge pipe, cancelled the discharging Blowing stopper; So can prevent top discharge pipe plug plug;
Because: be fixed with deep bead on the upper wall in the housing of last dryer, last deep bead is on top discharge mouth and the last dryer between the air outlet; Be fixed with deep bead down on the upper wall in the housing that descends dryer, following deep bead is between the following charging aperture of following air inlet that descends dryer and following dryer; Thereby: when using the utility model oven dry carborundum, can stop from the dry air of air inlet entering down and discharge from last air outlet through the top discharge pipe; Accumulate in the material top after water in the material is evaporated and go up in the dryer, dry air is held concurrently from last charging aperture and is gone up the air inlet entering, extracts out from last air outlet, takes the water that material is evaporated out of dryer in the lump; In addition, accumulate in the material top after the water in the following dryer in the material is evaporated down in the dryer, dry air gets into from air inlet down, extracts out from air outlet down, takes down the water that material is evaporated out of dryer in the lump; So can prevent the dry air air inlet phase mutual interference of two dryers.
In sum, the utility model prevents the top discharge pipe plug plug of dryer, and the drying efficiency of two dryers is not influenced with using, and continuous service has reduced personnel operation for a long time, has improved production efficiency.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated
A kind of novel drying unit comprises dryer 1 and following dryer 2, and the top discharge mouth 6 of last dryer 1 is connected with the following charging aperture 8 of following dryer 2 through the top discharge pipe 7 of last dryer 1; Be fixed with deep bead 16 on the upper wall in the housing of last dryer 1, last deep bead 16 is on top discharge mouth 6 and the last dryer 1 between the air outlet 5; Be fixed with deep bead 17 down on the upper wall in the housing that descends dryer 2, following deep bead 17 is between the following charging aperture 8 of following air inlet 11 that descends dryer 2 and following dryer 2.
The beneficial effect of the utility model is:
Because: a kind of novel drying unit, comprise dryer 1 and following dryer 2, the top discharge mouth 6 of last dryer 1 is connected with the following charging aperture 8 of following dryer 2 through the top discharge pipe 7 of last dryer 1; Thereby on top discharge pipe 7, cancelled top discharge Blowing stopper 9; So can prevent top discharge pipe 7 stops up;
Because: be fixed with deep bead 16 on the upper wall in the housing of last dryer 1, last deep bead 16 is on top discharge mouth 6 and the last dryer 1 between the air outlet 5; Be fixed with deep bead 17 down on the upper wall in the housing that descends dryer 2, following deep bead 17 is between the following charging aperture 8 of following air inlet 11 that descends dryer 2 and following dryer 2; Thereby: when using the utility model oven dry carborundum, can stop from the dry air of air inlet 11 entering down and discharge from last air outlet 5 through top discharge pipe 7; Accumulate in the material top after water in the material is evaporated and go up in the dryer 1, dry air is held concurrently from last charging aperture 4 and is gone up air inlet 4 entering, extracts out from last air outlet 5, takes the water that material is evaporated out of dryer 1 in the lump; In addition, accumulate in the material top after the water in the following dryer 2 in the materials is evaporated down in the dryer 2, dry air gets into from air inlet 11 down, extracts out from air outlet 12 down, takes down the water that material is evaporated out of dryer 2 in the lump; So can prevent the dry air air inlet phase mutual interference of two dryers.
In sum, the utility model prevents that the top discharge pipe 7 of dryer 1 from stopping up, and the drying efficiency of two dryers is not influenced with using, and continuous service has reduced personnel operation for a long time, has improved production efficiency.
