Abstract
The utility model discloses a graphite crucible which comprises a crucible body and a dust-proof cover arranged at the top of the crucible body. The inner wall of the crucible body is covered with a stick-proof inner layer, a discharge port and a discharge nozzle are arranged in the bottom of the crucible body, the discharge port is connected with the discharge nozzle through a discharge channel, and ventilation holes are arranged in the dust-proof cover. Compared with the prior art, the graphite crucible has the advantages that smooth discharge of volatile matter in the crucible is guaranteed, inner pressure of the crucible is reduced in time, and superfine powder is prevented from overflowing. Meanwhile, due to the timely discharge of the volatile matter, a temperature curve of the crucible can be quickened, and effects of saving electricity and saving time are achieved.
Description
Technical field
The utility model relates to graphite crucible, especially a kind of graphite crucible of overflow preventable.
Background technology
It is to be container with the common graphite crucible that tradition superfine powder graphitization is produced, pack in the acheson furnace, finish following process by certain heating curve: 200 ℃ → 200 ~ 1000 ℃ of preheatings are got rid of fugitive constituent → 1000 ~ 1500 and ℃ are finished carbonization → 1500 ℃ ~ 2300 ℃ and be converted into graphite-structure → 3000 and ℃ further improve graphitizing process.If meet the superfine powder fugitive constituent more than 8%, the fugitive constituent discharge rate is large, voltage rise height in the crucible, and superfine powder can be overflowed outside the crucible together along with fugitive constituent sometimes, causes the superfine powder yield to reduce, and directly affects economic benefit.
Simultaneously, press too high also easy initiation safety problem in the crucible, and the rate of climb that affects temperature curve, increasing energy consumption.Existing graphite crucible also is to propose solution for the problems referred to above, and pot life is also had a strong impact on, and the situation that crucible breaks happens occasionally.
The utility model content
The purpose of this utility model is to provide a kind of graphite crucible for the defective of prior art and deficiency, solves the problem that superfine powder is overflowed and crucible life is short.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of graphite crucible, comprise crucible body and the dust cap that covers in this bodies top, described crucible inner body wall is coated with antiseized internal layer, and the bottom of described crucible body is provided with discharging opening and discharging gate, described discharging opening is connected with discharging gate by tapping channel, and described dust cap is provided with passage.
Preferably,
Further, described tapping channel comprises vertical tapping channel and horizontal tapping channel, and described vertical tapping channel is perpendicular to described crucible body, and described interconnection is positioned at described discharging gate side.
After adopting said structure, the utility model beneficial effect compared with prior art is: graphite crucible of the present utility model can guarantee the straightway eliminating of fugitive constituent in the crucible, in time reduce the interior pressure of crucible, prevent overflowing of superfine powder, in time discharge owing to fugitive constituent simultaneously, the temperature curve of crucible can be accelerated, and reaches economize on electricity, saves effect consuming time.
Description of drawings
Fig. 1 is the structural representation of the graphite boiler of the utility model specific embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of graphite crucible, comprise crucible body 1 and the dust cap 2 that covers in this bodies top, described crucible inner body wall is coated with antiseized internal layer 3, the bottom of described crucible body is provided with discharging opening 4 and discharging gate 5, described discharging opening 4 is connected with discharging gate 5 by tapping channel, and described dust cap 2 is provided with passage 8.
Described tapping channel comprises vertical tapping channel 6 and horizontal tapping channel 7, and described vertical tapping channel 6 is perpendicular to described crucible body 1, and described interconnection 7 is positioned at described discharging gate side.
Antiseized internal layer 3 can prevent effectively that segmentation is bonded on the sidewall of crucible, and the design of passage 8 can make fugitive constituent get rid of fast, reduces the humidity in the crucible, reduces energy consumption.
Contrast test shows: with traditional common this section of crucible heating-up time be 15h, power consumption is at 130,000 KWH.After using band steam vent crucible instead, reduce 5h conduction time, electricity can use 30000KWH less, benefit situation 30000KWH * 0.65 yuan/KWH=19500 unit, 5h * 0.5 ton/h=2.5T * 5000 yuan/T=12500 unit can be 32000 yuan of increase profits.
The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
