Abstract

The shaped carbon processing apparatus with heat conducting oil as heating carrier consists of a heat conducting oil heating furnace, a heat conducting oil circulating pump, a high place heat conducting oil expanding tank, a screw extruder or straight stroke press, and a shaping and heating part. The heat conducting oil heated in the heating furnace before flowing out, and the outflow heat conducting oil is pumped with the circulating pump back to the furnace. During the processing, the damaged shaped carbon and other solid fuel are used as fuel to lower the power consumption.

Description

Type carbon processing device with heat conductive oil as heating carrier

What the present invention relates to is the type carbon processing device, here said type carbon is meant with the broken particle of plant and makes it become that have certain cross sectional shape and article surface and inner all or part of carbonization as raw material through extruding, heating, can be used for industry, civilian raw material or fuel.

The structure (see figure 1) of the at present widely used device that is used for processing type carbon mainly is made up of the profiled part 13 that screw extruder 12, outside with motor 11 drives are with electric heating element 14, the 15th, charging aperture, this apparatus structure is compact, and control ratio is more convenient.

But the disadvantage of this device is to need to consume a large amount of heating electric energy, make large-scale production be subjected to restriction, this shortcoming has also hindered the large-scale popularization of this technology on the other hand, because the raw material that is used to process extremely disperses, be present in vast rural area and forest products district in large quantities, the raw material that disperses transported to transport back after the processing stand processing again make land used, will certainly increase cost, reasonable method is that this device is made movably pattern, processing on the spot to each raw material production, is maximum obstacle but use electrically heated method.

The purpose of this invention is to provide a kind of type carbon processing device with heat conductive oil as heating carrier, come heater block or the incorporate moulding heater block of heating jacket outside profiled part with conduction oil through the heat transfer oil heater heating, be positioned at high-order outlet outflow through the high temperature heat conductive oil after the heating by it and enter heater block or the incorporate moulding heater block that is enclosed within outside the profiled part, the conduction oil of the lower temperature of outflow is sent heating again in the stove back to through circulating pump.

The carbonization of type carbon requires temperature about 250C °～300C °, and the maximum operating temperature of conduction oil relatively is fit to this use occasion at 350～420C °.Utilizing produce in the production process broken, residual type carbon and part finished product type carbon or other solid fuel is both economical way as the fuel of heat transfer oil heater, because the flue gas that produces when broken, residual type carbon and the carbon burning of finished product type is relatively cleaner, so making the air of the burner hearth that enters heat transfer oil heater give heat and utilization flue gas as air being given hot device heat this flue gas gives oven dry to raw material and handles, good energy-saving effect is arranged.

Technical characterstic of the present invention is: a kind of structural shape (see figure 2) with the type carbon processing device of heat conductive oil as heating carrier is the screw extruder 12 that drives by with motor 11, the profiled part 13 outer heater blocks 24 that are with, make the heat transfer oil heater 25 of fuel with solid fuel, chimney 80, place the drawer type raw material of exhaust gases passes 26 to give drying unit 27 and air gives hot device 28, conduction oil circulating pump 29, the high-order expansion slot 30 of conduction oil, tube connector 31,32 compositions such as grade, conduction oil circulation passage 22 is arranged in the heater block 24, the outlet that air gives hot device 28 has air exhauster 36 will give the burner hearth that air after the heat blasts heat transfer oil heater, above screw extruder 12, be equipped with the waste gas recovering device of forming by suction turbine machine 34 and water washing device 35 36, be recovered in the waste gas that produces in the raw material carbonisation and be used and do not pollute the environment.

The another kind of structural shape (see figure 3) of the type carbon processing device with heat conductive oil as heating carrier of the present invention is the forcing press 41 by the craspedodrome formula; be positioned at press base 60 and can go up; board-like moulding heater block 42 between the mobile down pressing plate 61; 43; make the heat transfer oil heater 25 of fuel with solid fuel; chimney 80; place the drawer type raw material of exhaust gases passes 26 to give drying unit 27 and air gives hot device 28; conduction oil circulating pump 29; the high-order expansion slot 30 of conduction oil; flexible connection pipe 51; 52; 53; 54 form; board-like moulding heater block 42; conduction oil circulation passage 44 is arranged in 43; 45; the outlet that air gives hot device has air exhauster 36 will give the burner hearth that air after the heat blasts heat transfer oil heater; press base 60 and can going up; down the pressing plate 61 that moves respectively with board-like moulding heater block 42; 43 link to each other and the centre is provided with heat insulation layer 62; 63 to reduce energy loss and to protect forcing press can not be operated in the too high temperature operating mode; the type of drive of the forcing press 41 of craspedodrome formula can be directly to drive or driven indirectly by the motor drives oil pump with manual mode or by motor, is equipped with the waste gas recovering device of being made up of suction turbine machine 34 and water washing device 35 36 above the forcing press 41 of craspedodrome formula.

Because the thermal coefficient of expansion of conduction oil is bigger, and the moulding heater block is placed on than the higher place of high temperature oil outlet, heat transfer oil heater top, can form Natural Circulation, conduction oil circulating pump 29 can.

When the chimney 80 of heat transfer oil heater had enough height, its draft effect was very strong, at this moment air give the air exhauster 36 of the outlet of hot device can.

Advantage of the present invention is that the broken particle of plant in farming, forestry and the city is made full use of, and reduces requirement, reduction power consumption to processing the required electric energy energy.
