Abstract
The utility model discloses a washing water-diversion automatic control device for dinonyl naphthalene sulfonate production, which comprises a controller and an automatic water-diversion mechanism arranged on a water outlet of a washing kettle; the automatic water distribution mechanism comprises a glass sight glass connected with a water outlet of the washing kettle, a spectrophotometer arranged on the side of the glass lens, a water discharge pipe arranged at the lower end of the glass lens and a water discharge branch communicated with the water discharge pipe through a joint; the automatic valve is arranged on the drain pipe, and the manual valve is arranged on the drain branch; the controller is in communication with the spectrophotometer and the automated valve. The utility model adopts the spectrophotometer to monitor the drainage condition in the glass lens, judges and controls through the change of transmittance or absorbance, and automatically opens and closes through the automatic valve, thus having high intelligent degree and good accuracy; meanwhile, the water distributor is also provided with a manual valve so as to avoid water distribution operation when power failure or other conditions occur.
Description
Technical Field
The utility model relates to a water washing and water dividing automatic control device for dinonyl naphthalene sulfonate production, and belongs to the field of chemical industry.
Background
In the production of dinonyl naphthalene sulfonate, water washing is an important process, and inorganic salt components in sulfonic acid are removed through multiple times of water washing, so that the product purity is improved. In the prior art, water diversion operation of washing generally comprises that a worker controls a water diversion end point through a sight glass, an obvious boundary or an emulsion layer is arranged between sulfonic acid and water, the worker observes the water flow condition through a glass sight glass, and a water diversion valve is closed immediately after clear water in the glass sight glass is converted into dark brown sulfonic acid or a milky emulsion layer, so that the water diversion operation is completed.
This kind of water diversion control mode needs the workman to continuously observe judgement and manual switching valve, has not only occupied the human cost, and appears easily that the operation untimely leads to the material to leak. Especially need the inspection of workman cauldron when having many cauldron materials to divide simultaneously, waste time and energy, and the untimely or misoperation that appears more easily leads to the material leakage problem of operation.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects, the utility model provides a water washing and water dividing automatic control device for dinonyl naphthalene sulfonate production, which adopts the technical scheme that:
a water washing water-dividing automatic control device for dinonyl naphthalene sulfonate production comprises a controller and an automatic water-dividing mechanism arranged on a water outlet of a water washing kettle; the automatic water distribution mechanism comprises a glass sight glass connected with a water outlet of the washing kettle, a spectrophotometer arranged on the side of the glass lens, a water discharge pipe arranged at the lower end of the glass lens and a water discharge branch communicated with the water discharge pipe through a joint; the automatic valve is arranged on the drain pipe, and the manual valve is arranged on the drain branch; the main body of the spectrophotometer is arranged on one side of the glass lens, and the light source of the spectrophotometer is arranged on the other side of the glass lens; the controller is in communication with the spectrophotometer and the automated valve.
Further, the light source of the spectrophotometer is a sodium lamp.
Further, the automatic valve is an electric valve or a pneumatic valve.
Further, the electric valve is an electromagnetic valve.
Compared with the prior art, the utility model has the beneficial effects that: the utility model adopts the spectrophotometer to monitor the drainage condition in the glass lens, judges and controls through the change of transmittance or absorbance, and automatically opens and closes through the automatic valve, thus having high intelligent degree and good accuracy. Meanwhile, the utility model is also provided with a manual valve to avoid water diversion operation when power failure or other conditions occur.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solution of the present invention is further described below with reference to the accompanying drawings and examples.
Example (b):
referring to fig. 1, a water washing and water dividing automatic control device for dinonyl naphthalene sulfonate production comprises a controller (not shown) and an automatic water dividing mechanism installed on a water outlet of a water washing kettle; the automatic water distribution mechanism comprises a glass sight glass 2 connected with a water outlet 1 of the washing kettle, a spectrophotometer 3 arranged on the side of the glass lens 2, a water discharge pipe 4 arranged at the lower end of the glass lens 2 and a water discharge branch 5 communicated with the water discharge pipe 4 through a joint; the drain pipe 4 is provided with an electromagnetic valve 6, and the drain branch 5 is provided with a manual valve 7; the main body of the spectrophotometer 3 is arranged on one side of the glass lens 2, and a light source sodium lamp 30 of the spectrophotometer 3 is arranged on the other side of the glass lens 2; the controller is connected and communicated with the spectrophotometer 3 and the electromagnetic valve 6.
The working principle of the utility model is that the water flow in the glass lens is monitored by a spectrophotometer by utilizing the difference of transmittance and absorbance among clear water, dark brown sulfonic acid and milky emulsion layers, and the water diversion completion condition is judged by utilizing the change of the transmittance or the absorbance so as to realize automatic and accurate water diversion control.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the utility model.
