The utility model provides a drive sour device for nitrocotton production, the flow and the colour of the acid nitrocotton of liquid can be monitored to the device, and then the operation of control centrifugal separator.
Description
Technical field
The utility model relate to a kind of for nitro-cotton produce drive sour device, belong to nitro-cotton production equipment field.
Background technology
In nitro-cotton production process, purified cotton and nitration mixture generation nitration reaction generate acid nitro-cotton, and acid nitro-cotton transports by driving sour device again.At present, drive sour device and comprise whizzer, conduction pipe, receiving tank, carry out solid-liquid separation after acid nitro-cotton enters whizzer, liquid is connected with conduction pipe by whizzer liquid exit, is transported to receiving tank, owing to there is no monitoring mechanism after whizzer, cannot monitor conduit running situation (flow), cause the running condition cannot understanding whizzer in time, cause the frequent putty of whizzer, fracture etc., and then cause the maintenance that stops production, affect the production of nitro-cotton.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of produce for nitro-cotton drive sour device, described device can the flow of the acid nitro-cotton of monitoring liquid and color, and then the operation of monitoring whizzer.
The utility model solve that its technical problem adopts a kind of produce for nitro-cotton drive sour device, comprise whizzer, conduction pipe group, receiving tank, described conduction pipe group comprises the first pipeline, second pipe, described first pipeline mates with whizzer liquid exit and is connected, described second pipe mates with receiving tank and is connected, also comprise corrosion resistant perspective pipeline, described corrosion resistant perspective pipeline one end is mated with the first pipeline and is connected, and the other end mates with second pipe and is connected.
Further, described corrosion resistant perspective pipeline is connected with the first pipeline and has an X-rayed the mode that pipeline is connected with second pipe with corrosion resistant and all adopt ring flange to connect.
Further, connect by strengthening keel between described ring flange.
Further, also comprise flexible connection structure, described flexible connection structure is arranged between the first pipeline and whizzer.
Further, described flexible connection structure is soft metal corrugated tube.
Further, also comprise flow control valve, described flow control valve is arranged between second pipe and receiving tank.
Further, described flow control valve is pneumatic flowrate variable valve.
The beneficial effects of the utility model are: corrosion resistant perspective pipeline one end is mated with the first pipeline and is connected, the other end mates with second pipe and is connected, be between the first pipeline and second pipe, arrange corrosion resistant have an X-rayed pipeline, that is to say that between whizzer and receiving tank, arrange corrosion resistant has an X-rayed pipeline, flow and the color of liquid acidic nitro-cotton conveniently can be monitored by corrosion resistant perspective pipeline, and then the running condition of whizzer can be learnt in time, reduce the failure rate of whizzer, thus reduce the maintenance cost of whizzer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Component, position and numbering in figure: whizzer 1, first pipeline 2, receiving tank 3, second pipe 4, corrosion resistant perspective pipeline 5, reinforcement keel 6, flexible connection structure 7, flow control valve 8.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model a kind of for nitro-cotton produce drive sour device, comprise whizzer 1, conduction pipe group, receiving tank 3, conduction pipe group comprises the first pipeline 2, second pipe 4, first pipeline 2 mates with whizzer 1 liquid exit and is connected, second pipe 4 mates with receiving tank 3 and is connected, also comprise corrosion resistant perspective pipeline 5, corrosion resistant perspective pipeline 5 one end is mated with the first pipeline 2 and is connected, the other end mates with second pipe 4 and is connected, be between the first pipe 2 road and second pipe 4, arrange corrosion resistant have an X-rayed pipeline 5, that is to say that between whizzer 1 and receiving tank 3, arrange corrosion resistant has an X-rayed pipeline 5.Because the material of conveying is acid nitro-cotton, there is severe corrosive, so select corrosion resistant to have an X-rayed pipeline 5, corrosion resistant perspective pipeline 5 is the material of photoscope can make pipe-like, has perspective function, conveniently can monitor flow and the color of liquid acidic nitro-cotton outside, and then the running condition of whizzer 1 can be learnt in time, reduce the failure rate of whizzer 1, thus reduce the maintenance cost of whizzer 1, ensure the normal operation of equipment.
Concrete, have an X-rayed pipeline 5 and the first pipeline 2 and corrosion resistant to make corrosion resistant and have an X-rayed pipeline 5 and to be connected with second pipe 4 and to have stronger intensity, they can adopt ring flange to connect at the mode of connection.Ring flange strength of joint is high, and stability is strong, and result of use is good.In order to further strengthen their strength of joint, also can connect by strengthening keel 6 between ring flange, strengthening keel 6 and can adopt the steel that intensity is high.
Concrete, owing to there is strong vibration when whizzer 1 runs, in order to reduce the vibration of whizzer 1 to the damage, particularly corrosion resistant perspective pipeline 5 of drawing together the first pipeline 2, second pipe 4, corrosion resistant perspective pipeline 5, due to material, easier due to whizzer 1 vibration cause damage.The utility model is also provided with flexible connection structure 7, flexible connection structure 7 is arranged between the first pipeline 2 and whizzer 1, flexible connection structure 7 is for absorbing the vibration of whizzer, flexible connection structure 7 can use metallic bellows, metallic bellows is usually used in connecting between pipeline, result of use is good, and spare parts is convenient, for ease of maintenaince.
Concrete, for the ease of regulating the flow of conduction pipe group, between second pipe 4 and receiving tank 3, be provided with flow control valve 8, flow control valve 8 is pneumatic flowrate variable valve.Pneumatic flowrate variable valve is convenient to Automated condtrol.
