Description
Technical field
The invention belongs to use resistance furnace technical field of smelting, it is related to a kind of resistance furnace and comes out of the stove scheme, be specifically designed
A kind of resistance furnace of silicon carbide smelting is come out of the stove scheme.
Background technique
Resistance furnace is usually made of headwall, side wall, siege, when the side wall of smelting furnace is mounted on smelting furnace, headwall, side
Wall, siege just constitute the cabinet of a uncovered.
The tradition scheme of coming out of the stove is: when product, which is smelted, completes come out of the stove work, the nothing that is made of headwall, side wall, siege
The intracorporal charge-temperature of top box is up to several thousand degrees celsius, disassembly side wall come out of the stove the resistance furnace of operation, scene is usually all
Be first to disassemble side wall, go out furnace charge and large area is exposed in environment, by natural cooling and water it is cooling after, with grabbing
Bucket, loading machine etc. complete furnace charge and come out of the stove operation；And resistance furnace non-detachable for side wall, work of coming out of the stove usually all are natures
It is cooling and the furnace charge in furnace is caught into resistance furnace after largely watering is cooling, it completes furnace charge and comes out of the stove work.
Aforementioned work of coming out of the stove is intermittent operation scheme, and working efficiency is low and fugitive dust is very serious, is unfavorable for cleaning, efficiently life
It produces.
For silicon carbide smelting resistance furnace, work of coming out of the stove is come out of the stove other than work in addition to completing furnace charge, and there are also product crystallization cylinders
It comes out of the stove.Come out of the stove rooting out including crystallization cylinder outer cover skin and the work of coming out of the stove of crystallization cylinder, rooting out for conventional method lid skin is all artificial
It completes, labor intensity of workers is big, operating environment is very poor.
Summary of the invention
The purpose of the present invention is for existing resistance furnace come out of the stove scheme the shortcomings that, the high-efficiency environment friendly for providing a kind of resistance furnace goes out
Furnace scheme.
The technical scheme is that such: a kind of resistance furnace discharging device, by cart, trolley, lifting device, conveying
Device composition.
The cart is exactly that can realize the running gear that back and forth run along resistance furnace length direction on resistance furnace, on cart
Trolley and conveying device be set, sets carriage walking track along cart span direction on cart, runs trolley back and forth on cart.
According to field condition, cart can select gate-type or bridge-type framework, and this programme schematic diagram show gate-type framework.
The trolley is mounted on cart, is back and forth run in orbit along cart span direction.Promotion dress is set on trolley
It sets, and move up and down lifting device can on trolley.
The lifting device is installed on trolley, for promoting the furnace charge in resistance furnace, endfeed upper end under lifting device
Discharging, lifting device itself can also move back and forth above and below other than it can run with large and small vehicle, with the operation of large and small vehicle
And lifting device itself moves up and down, and runs lifting device lower end to any space of resistance furnace, realizes to resistance
The operation of coming out of the stove of any spatial position furnace charge in furnace.
The usually mating discharging slip pipe in the upper end of lifting device, slides the furnace charge from lifting device to conveying device.It mentions
The lower end for rising device usually sets running gear, running gear auxiliary lifting apparatus self-operating, when running gear is walked and big garage
It walks and keeps same step.Lifting device feeding is given for convenience, usually sets drawing-in device in its lower end.
According to field condition, lifting device usually selects bucket elevator class but is not limited only to select bucket elevator class.Tradition bucket mentions
Machine is all pedestal installation and its position is fixed, and is arranged to what its fuselage moved up and down on trolley here,
Its lower end is typically provided with running gear and drawing-in device.
In order to effectively control the dust of operating environment or accelerate the cooling velocity of furnace charge, spray is set usually on lifting device
Shower device is used for spray cooling or dust suppression.
The conveying device is set on cart, and length direction will be from promotion with cart span direction, conveying device
The furnace charge of device is sent to target position, completes operation of coming out of the stove.
Conveying device usually selects belt conveyor but is not limited only to select belt conveyor.
In this way, lifting device itself moves up and down and with trolley travelling, trolley is run with cart, is operated the resistance furnace and is gone out
Furnace apparatus makes the drawing-in device of lifting device lower end reach target position, and furnace charge in furnace is divided from top to bottom, along furnace superintendent direction
Layer, line by line continuous " shovel is cut " make furnace charge enter lifting device, and boosted device slides to conveying again through discharging slip pipe after being promoted and fills
It sets, is sent by conveying device to target position, complete furnace charge and come out of the stove operation.
Candidate device: special, a kind of silicon carbide resistance furnace crystallization cover skin shoveling device by cart and is mounted on cart
On excavator excavate arm assembly constitute.Cart is run to target position, arm assembly work is excavated in operation, with the shovel on assembly
The lid skin being wrapped in outside silicon carbide crystallization cylinder is continuously rooted out as tooth arable land, that completes lid skin roots out work.Shoveling lid skin is exactly to be commonly called as
Shovel Calusena lansium.Lid skin, ingot, graphite can select scraper bowl to complete work of coming out of the stove.
Optional: a kind of resistance furnace shove charge device sets feeding device on trolley, feed device is set on cart, constitutes
Resistance furnace shove charge device.Endfeed lower end discharges on feeding device.Feed device gives feeding device feeding.Feeding device is with trolley
Operation, trolley are run with cart, and operating the resistance furnace shove charge device makes the lower end of feeding device reach target position, will be to shove charge
Material first send on feed device and by feed device and feeds feeding device, flow in resistance furnace through feeding device, makes furnace charge under
Upwards along in furnace superintendent the direction successively continuous loading resistance furnace of branch, shove charge operation is completed.The feeding device is exactly one in fact
Flow tube, flow tube lower end are usually scalable to change length for adjusting the height of flow tube lower end.The feed device is usually selected
Belt conveyor but be not limited only to select belt conveyor.Traditional Method shove charge is with a pipeful of interrupted dress of crane for hoisting suspension bucket
Furnace, effect is extremely low.
Aforementioned, lifting device and feeding device can be located on same trolley, trolley can also be divided to be arranged；It can be on cart
It is that single crab is also possible to double trolley or without trolley；Can choose cart also can choose across a resistance furnace across two resistance
Furnace.
The present invention has following remarkable result:
1, the configuration of the present invention is simple, cheap, assembly are easy.
