Abstract
The utility model discloses a nitrogen introducing oxygen-resistance device of carbonization furnaces, which comprises two nitrogen gas cylinders and a breather pipe fixedly arranged on a sealing furnace mouth; the tail ends of the breather pipe are respectively communicated with a reservoir which is provided with valves; the valve is communicated with the two nitrogen gas cylinders; and the two valves are arranged on the reservoir and respectively communicated with the two nitrogen gas cylinders by a pipeline. When the device is used, the nitrogen gas is introduced into the breather pipe and the nitrogen introducing oxygen-resistance process is carried out on raw material and gas enter the carbonization furnace. As the nitrogen gas is simultaneously introduced into the sealing furnace mouth by the same nitrogen gas cylinder, the nitrogen gas spouting from the tail ends of the breather pipe on the sealing furnace mouth is uniform, thus being convenient for the nitrogen introducing oxygen-resistance sealing of the sealing furnace mouth.
Description
Technical field
The utility model relates to the logical nitrogen resistance oxygen device that uses on a kind of carbide furnace.
Background technology
At present, carbide furnace is a nucleus equipment with the fiber carbonization in the carbon fiber production equipment.Fiber is before entering carbide furnace, and (about 0.5-4min) is exposed in the air for some time, thereby can absorb more airborne oxygen-containing molecules, and the effect of logical nitrogen resistance oxygen device will enter the incidental oxygen-containing molecules of fiber of carbide furnace exactly and remove.Existing logical nitrogen resistance oxygen device comprises the air jet pipe that is installed in the sealing converter nose, and the air jet pipe of two three way types generally is installed, and two air jet pipes form four spouts above fiber, the other end of two air jet pipes respectively with two nitrogen cylinders (A bottle and B bottle are connected).The shortcoming of this version is, when the nitrogen in the nitrogen cylinder wherein uses up when needing to change nitrogen cylinder, need another nitrogen cylinder to supply with two air jet pipes simultaneously for some time, cause the nitrogen of spout ejection of two air jet pipe ends inhomogeneous easily, be unfavorable for logical nitrogen resistance oxygen sealing, influence the carbonization of fiber and the service life of equipment carbide furnace.
The utility model content
The technical problems to be solved in the utility model provides a kind of even and logical nitrogen resistance of carbide furnace that be convenient to control oxygen device of nitrogen that sprays.
For solving the problems of the technologies described above, the logical nitrogen resistance of the carbide furnace that is provided oxygen device comprises nitrogen cylinder, its design feature is also to comprise the breather pipe that is packed in the sealing converter nose, the end of breather pipe is connected with holder respectively, and holder is provided with valve, and valve is communicated with described nitrogen cylinder.
After adopting said structure, because breather pipe is packed in the top of sealing converter nose, the end of breather pipe is connected with holder respectively, holder is provided with valve, valve is communicated with described nitrogen cylinder, during use, in breather pipe, feed nitrogen, raw material and the gas that enters carbide furnace is led to the processing of nitrogen resistance oxygen.Owing to feed nitrogen simultaneously in the sealing converter nose by same nitrogen cylinder, the nitrogen of the terminal ejection of air jet pipe on the sealing converter nose is even, is convenient to seal the logical nitrogen resistance oxygen sealing of converter nose.
As improvement of the present utility model, described nitrogen cylinder is established two altogether, and holder is provided with two valves, and two valves are communicated with two nitrogen cylinders by pipeline respectively.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The logical nitrogen of carbide furnace hinders the oxygen device as shown in drawings, comprise two nitrogen cylinders 1 (can be provided with a plurality of as required), two nitrogen cylinders 1 are respectively equipped with Pressure gauge and switch, two nitrogen cylinders 1 link to each other with memory 3 by pipeline respectively, be respectively equipped with valve 5 (comprising valve A and valve B) on two pipelines, be communicated with four breather pipes 2 on the memory 3, the other end of breather pipe 2 is connected with the tracheae of sealing on the converter nose 4.Above sealing converter nose 4, also be provided with exhaust steam passage, by air exhauster with nitrogen with and the gas that blows out extract out.
During use, the valve-off A (perhaps valve B) of elder generation, open the pairing nitrogen cylinder 1 of valve B (perhaps valve A), in breather pipe 2, feed nitrogen by memory 3, owing to use same nitrogen cylinder 1, so in sealing converter nose 4 outlet side of each tracheae to go out atmospheric pressure consistent with flow, nitrogen is evenly distributed; After using one bottle of nitrogen cylinder 1, valve B (perhaps valve A) is closed, open valve A (perhaps valve B), open another bottle nitrogen cylinder 1, again by memory 3 in breather pipe 2, feeding nitrogen, when changing nitrogen cylinder 1, can not cause the nitrogen of each tracheae outlet side in sealing converter nose 4 to spray non-uniform phenomenon so yet.
Claims (2)
1. the logical nitrogen of carbide furnace hinders the oxygen device, comprise nitrogen cylinder (1), it is characterized in that also comprising the breather pipe (2) that is packed in sealing converter nose (4), the end of breather pipe (2) is connected with holder (3) respectively, holder (3) is provided with valve (5), and valve (5) is communicated with described nitrogen cylinder (1).
2. the logical nitrogen resistance of carbide furnace according to claim 1 oxygen device, it is characterized in that: described nitrogen cylinder (1) is established two altogether, and holder (3) is provided with two valves (5), and two valves (5) are communicated with two nitrogen cylinders (1) by pipeline (6) respectively.
