Technical field
The utility model is related to a kind of CABLE MATERIALS process equipment, specifically a kind of to be used to produce low smoke and zero halogen reworked material
Batch mixing heater.
Background technology
When carrying out the production of low smoke and zero halogen reworked material, it is necessary first to which it is dry that block or particulate matter to crushing carry out heating
It is dry, the water content of block or particulate matter is reduced to less than 0.1%.Existing firing equipment is generally dryer or drying machine, this
The problems such as a little equipment generally existing heat time length, the efficiency of heating surface are low, material is heated uneven, causes the low smoke and zero halogen regeneration of production
Expect that product quality is poor.
Utility model content
The purpose of this utility model is just to provide a kind of batch mixing heater for being used to produce low smoke and zero halogen reworked material, to solve
The problem of certainly existing firing equipment efficiency is low, heating effect is poor.
What the utility model was realized in:A kind of batch mixing heater for being used to produce low smoke and zero halogen reworked material, including
Frame, the mixing machine and hot air apparatus being arranged in the frame;Exhaust duct and electricity are provided with the top of the mixing machine
Machine, is provided with discharge duct and loading hopper on the bottom cylinder of the mixing machine, cylinder is internally provided with the mixing machine
Shape sleeve, is internally provided with vertical type helical feed auger in the sleeve, is provided with the bottom of the helical feed auger
Charging aperture, in the top sidewall of the helical feed auger be provided with discharge nozzle, the top of the helical axis of helical feed auger with
The motor drive connection, the bottom of the helical axis of helical feed auger is connected to the bottom of mixing machine by bearing;The heat
Wind apparatus includes blower fan and the heater being connected with the air outlet of the blower fan, and the air outlet of the heater passes through pipeline and institute
State the inside connection of sleeve.
Extension straight down, the spiral shell of the helical feed auger are provided with the bottom of the mixing machine lower cylinder
The bottom of spin axis is connected in extension by bearing, and the loading hopper is arranged on the side wall of extension.
Screen pack is provided with the exhaust duct.
The utility model also include electric cabinet, the motor, the blower fan and the heater respectively with the electric cabinet
Electrical connection.
Operation principle of the present utility model is:
Motor provides driving force for helical feed auger, and driving helical feed auger will enter mixing machine bottom from loading hopper
At the top of the material lifting in portion to auger, the discharge nozzle for being promoted to material from the helical feed auger at top is discharged into the inner chamber of sleeve
In, and start to fall under gravity;Simultaneously, blower fan introduces extraneous cold wind in heater after heating, obtained heat
Wind enters in the inner chamber of sleeve;In sleeve, hot blast and the material-heat-exchanging fallen, to material heat drying, the wind folder after heat exchange
With moisture from the exhaust duct discharge at the top of mixing machine, and material then falls back to the bottom of mixing machine;Fall back to mixing machine bottom
Material again by helix transporting device lifting at the top of sleeve, and again with the hot air heat exchange from hot air apparatus in sleeve,
So repeatedly, until material is fully dried.After batch mixing heating is finished, motor, blower fan and heater are closed, treats that material is fallen after rise to material
Behind cylinder bottom, discharge duct is opened, material is discharged.
The beneficial effects of the utility model:
The utility model is simple in construction, easy to operate, material can be made multi-faceted heated, storeroom is heated evenly, heating effect
Rate is high, is substantially shorter the heat time, reduces heating cost, and it is heated after material moisture it is extremely low.

Embodiment
It is made up of as shown in figure 1, the utility model is main the part such as frame 1, mixing machine 2, hot air apparatus and electric cabinet.
Frame 1 is formed by connecting by some hack levers, is fixed on the ground, to support the other structures such as mixing machine 2, to ensure
The structural stability of whole device.
Mixing machine 2 is arranged in frame 1, and it includes top cylinder and lower cylinder, and its middle and upper part cylinder is cylindrical, under
Portion's cylinder is inverted coniform.The top of top cylinder is closed, and exhaust duct 3 is provided with the top of the cylinder of top,
Screen pack is provided with exhaust duct 3.Extension 12 straight down, the bottom of extension 12 are provided with the bottom of lower cylinder
On the hack lever for being connected to frame 1, dustpan type loading hopper 6 is provided with the side wall of extension 12.On the side wall of lower cylinder
Provided with discharge duct 5, discharge valve is provided with discharge duct 5.
Cylindrical sleeve 7 is internally provided with mixing machine 2, the central shaft of the sleeve 7 and the central shaft weight of mixing machine 2
Close, the inner chamber of sleeve 7 is the place of batch mixing heat drying.Vertical type helical feed auger 8 is internally provided with sleeve 7,
The bottom of the helical feed auger 8 is feed end, and top is discharge end.The feed end of helical feed auger 8 stretches into extension 12
It is interior, and the bottom of its helical axis is connected by bearing with extension 12, loading hopper 6 is connected with the feed end of helical feed auger 8,
Auger discharging pipe 9 is provided with the top sidewall of helical feed auger.The top of mixing machine 2 is provided with motor 4, helical feed
The top of the helical axis of auger 8 is connected with motor 4.Start motor 4, the helical axis rotation of helical feed auger 8, loading hopper
Material in 6 enters in extension 12, after auger top discharge end is arrived by helical axis lifting, is entered by auger discharging pipe 9
In sleeve 7, and fall under gravity.
Hot air apparatus includes blower fan 10 and heater 11, and the air inlet of blower fan 10 communicates with outside air, its air outlet and
The air inlet of heater 11 is connected, and the air outlet of heater 11 is connected by pipeline with the inside of sleeve 7.Blower fan 10 draws wind
Enter after being heated in heater 11, obtained hot blast enters inside sleeve 7, with the material-heat-exchanging slowly fallen in sleeve 7, heat exchange
Wind afterwards has been carried moisture secretly and discharged from the exhaust duct 3 at the top of mixing machine 2, and material is then fallen after rise to the bottom of mixing machine 2.The thing of falling
Material is promoted to the top of sleeve 7 by helical feed auger 8 again, and in sleeve 7 with the hot air heat exchange from hot air apparatus, so
Repeatedly, the purpose of batch mixing heating is reached.
Keying of the electric cabinet to control each part mentioned above, motor 4, blower fan 10 and heater 11 are electrically connected with electric cabinet respectively
