Background

In the field of tobacco manufacture, high-temperature steam is an indispensable production element, and can be used in the production processes of tobacco shred drying, tobacco leaf heating and the like. After the steam is generated, the steam is usually conveyed to the sub-cylinders by using steam pipelines and then conveyed to each tobacco production link by the sub-cylinders. After the existing sub-cylinder is used and stopped, steam in the pipeline can be liquefied into condensed water on the inner wall of the pipeline, and if the condensed water is not removed, the condensed water is easily collected in the pipeline, so that a water hammer is formed and the loss of the pipeline is accelerated. The conventional means is to open the drain valve at the bottom end of the gas dividing cylinder to drain liquid water after stopping use, and close the drain valve to continue use before starting use, however, because the steam pipeline for transportation is longer and because the pipeline is mostly horizontally arranged, condensed water does not flow into the gas dividing cylinder to be drained, the draining effect is poor, and operators are required to manually operate the drain valve, and the pressure of the operators is high, especially in some spaces where pipelines are densely arranged.

As shown in fig. 1-2, the present utility model provides an air dividing apparatus for automatically discharging condensed water, comprising a dividing cylinder 1, an air inlet pipe 2 and an air outlet pipe 3. The air inlet pipeline 2 and the air outlet pipeline 3 are communicated with the sub-cylinder 1. After the air inlet pipeline 2 supplies hot steam to the sub-cylinders 1, the steam is transported to each tobacco manufacturing process by the air outlet pipeline 3. The bottom of the split cylinder 1 is provided with a drainage pipeline 4, and the drainage pipeline 4 is used for draining condensed water generated in the split cylinder 1, the air inlet pipeline 2 and the air outlet pipeline 3. The drainage pipeline 4 is also provided with a stop valve 5 and an electric valve 6 in sequence. The stop valve 5 is arranged between the electric valve 6 and the sub-cylinder 1, and the stop valve 5 and the electric valve 6 are used for controlling the opening and closing of the drainage pipeline 4, and the drainage pipeline 4 can drain condensed water generated in the sub-cylinder 1 only when the stop valve and the electric valve are opened. It is worth noting that the stop valve 5 in the device is kept in a normally open state when in use, and can be closed only when the equipment is overhauled. The drain pipe 4 is further provided with a temperature sensor 7 and a pressure sensor 8 for detecting the temperature and pressure in the drain pipe 4. The temperature sensor 7 and the pressure sensor 8 may be provided between the shutoff valve 5 and the electric valve 6, or may be provided before the shutoff valve 5. The temperature sensor 7 and the pressure sensor 8 can detect parameters in the drainage pipeline 4 and parameters in the sub-cylinder 1, and the part of the air outlet pipeline 3 positioned in front of the electric valve 6 can be regarded as a whole body of the sub-cylinder 1 because the stop valve 5 is kept in a normally open state.

The temperature sensor 7 and the pressure sensor 8 are both in communication connection with the electric valve 6 for simultaneously controlling the opening and closing of the electric valve 6. In particular, the apparatus further comprises a processor 9. The input of the processor 9 is communicatively connected to the temperature sensor 7 and the pressure sensor 8, and the output of the processor 9 is communicatively connected to the electrically operated valve 6. The processor 9 receives the steam parameters sent by the pressure sensor 8 and the temperature sensor 7, and outputs a control signal for the electric valve 6 based on a preset processing mode. The electric valve 6 may be an electric ball valve, an electric gate valve, an electric butterfly valve, or the like.

In the utility model, the temperature and pressure of steam in the split cylinder 1 are detected in real time, and the opening and closing of the electric valve 6 are automatically controlled by the steam parameters changed during the steam opening and closing. For example, when the production is stopped, the air inlet pipeline 2 is not used, or the steam is gradually reduced to be delivered to the sub-cylinders 1, the temperature and the pressure in the sub-cylinders 1 are reduced to a certain extent, the processor 9 judges that the sub-cylinders 1 are not operated at this time based on the preset temperature threshold value and the preset pressure threshold value, and then sends a control command to the electric valve 6 to control the electric valve 6 to be kept open, so that condensed water is discharged, and at the moment, the condensed water and part of steam in the pipeline are discharged from the electric valve 6. When production begins, steam generated by the boiler is gradually transmitted to the sub-cylinder 1, when the temperature and the pressure of the steam do not reach the threshold value, the processor 9 does not control the electric valve 6 to be closed, at least condensed water which cannot be reserved in the sub-cylinder 1 in the air inlet pipeline 2 can be gathered to the sub-cylinder 1 under the purging of the steam, and then is discharged from the electric valve 6, when the temperature and the pressure of the steam are both raised to exceed the threshold value, the processor 9 judges that the condensed water is discharged, controls the electric valve 6 to be closed, and finishes the automatic discharging of the condensed water. Notably, the temperature and pressure thresholds may be set empirically or after multiple experiments.

In order to facilitate the smooth condensation of the steam in the sub-cylinder 1 after the production is stopped, a plurality of vertically placed deflectors 10 are arranged at the top in the sub-cylinder 1. As shown in fig. 3, the baffle 10 is an arcuate plate. The length of the baffle 10 in the height direction of the sub-cylinder 1 is smaller than the inner diameter of the sub-cylinder 1. The baffle 10 is vertically placed so as to be perpendicular to the transport direction of the steam so that the steam can sufficiently contact the baffle 10 for condensation. Preferably, a material having a lower specific heat capacity is selected as the material for manufacturing the baffle 10, so that when the production is stopped, there is no heating of the steam, the temperature of the baffle 10 can be rapidly lowered, and the steam can be more rapidly condensed on the baffle 10; conversely, at the beginning of production, the baffle 10 can be heated up quickly under the heating of the steam, so as to reduce the loss of steam when the steam passes normally. The length of the baffle 10 is set smaller than the inner diameter of the split cylinder 1 in order to avoid the baffle 10 from affecting the discharge of condensed water at the bottom of the split cylinder 1. The guide plate 10 can also be set to be a rotatable structure, and the rotation axis is the diameter in the vertical direction of the sub-cylinder 1, so, when the sub-cylinder 1 works, the guide plate 10 is parallel to the gas flow direction, the contact area between steam and the guide plate 10 is smaller, the influence on the steam transportation is avoided, and when the sub-cylinder 1 stops working, the guide plate 10 rotates to be perpendicular to the residual steam transportation direction and fully contacts with the steam. Specifically, the top of the baffle 10 is provided with a rotating shaft 11. One end of the rotating shaft 11 is connected with the guide plate 10, and the other end of the rotating shaft penetrates out of the split cylinder 1 to be connected with an external driving motor. The rotation of the baffle 10 is controlled by a driving motor.

The baffle 10 is provided with a flow guide groove 12 extending along the height of the baffle 10. In the utility model, the diversion trench 12 is arranged so that liquid water formed by condensation on the diversion plate 10 can fall into the bottom of the sub-cylinder 1 to be discharged.

The device further comprises a leg 13. The legs 13 are used for mounting the sub-cylinder 1 to a specified height to facilitate the arrangement of the drain pipe 4 and the like.

The application method of the utility model is as follows:

after production is stopped, the deflector 10 is controlled to rotate to fully contact steam, so that the condensation of the steam is accelerated, and when the steam pressure and the temperature in the sub-cylinder 1 are lower than the threshold values, the electric valve 6 is controlled to be opened, and the condensed water is automatically discharged; when the starting equipment is used for production, the guide plate 10 rotates to be parallel to the steam transportation direction, the loss of steam is reduced, when the steam pressure and the temperature in the split cylinders 1 are higher than the threshold value, the processor controls the electric valve 6 to be closed, the condensed water discharge is completed, and normal production is continued, so that automatic discharge control of the condensed water is realized, and the work load of operators is lightened.

The above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present utility model, which is intended to be covered by the scope of the claims of the present utility model.
