Abstract
The utility model discloses a profenofos condensation PH detection and adjustment automatic control device, which comprises a condensation kettle, an alkali dropwise adding tank, a PH online tester, a control cabinet and an automatic feeding valve, wherein the PH online tester is arranged in the condensation kettle, the PH online tester is connected onto the control cabinet, the automatic feeding valve is further connected and controlled by the control cabinet, and two ends of the automatic feeding valve are respectively connected with the condensation kettle and the alkali dropwise adding tank; and a control valve is connected between the alkali dropwise adding tank and the automatic feeding valve. The device adopts the combined control of online PH value measurement and automatic liquid alkali supplementing device, improves production conditions, changes the current situation of overlarge differences between manually controlled batches, and makes the condensation production more stable.
Description
Technical field
The utility model relates to a kind of chemical production device, and specifically a kind of PH detects and adjusts automaton.
Background technology
What the detection of Profenofos condensation reaction pH value adopted is artificial extensively PH detection paper, and adjusting is also manually to mend the alkali mode.This mode is produced the people for adjusting frequency greatly, and testing result and benefit alkali are subject to man's activity larger, and labor strength is high, and the efficiency of production is low.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of Profenofos condensation PH and detects the adjustment automaton, and this apparatus structure is simple, can realize that PH detects adjustment and automatically controls, and the minimizing labor strength, enhance productivity.
For solving the problems of the technologies described above, a kind of Profenofos condensation PH of the present utility model detects and adjusts automaton, comprise that condensation kettle, alkali drip tank, PH on-line determination instrument, switch board and auto feed valve, be provided with PH on-line determination instrument in described condensation kettle, described PH on-line determination instrument is connected on switch board, described switch board also connects and controls the auto feed valve, and the two ends of described auto feed valve connect respectively condensation kettle, alkali drips tank.
As the further improvement to the technical program, described alkali drips tank and goes out to be connected with by-pass valve control.
As the further improvement to the technical program, described by-pass valve control is connected to described alkali and drips between tank and described auto feed valve.The valve increased can be realized the emergency control in the chemical reaction process.
The course of work of this equipment is as follows: when reaction mass reacts at condensation kettle, at automatic control cabinet, set the PH range of control, PH on-line determination instrument is measured PH within area requirement the time, and switch board is controlled automatic valve in closed condition; When pH value, during lower than desired numerical value, PH on-line determination instrument is measured and is fed back to switch board, and switch board is controlled automatic valve and added liquid caustic soda, add on pH value in limited time, automatically stop adding.The use of this device greatly improves processing safety, stability and automatization level.And adopt online pH value to measure and automatic makeup adds the liquid caustic soda device and jointly controls, improved working condition, changed the people for the time control batch between mistake big-difference present situation, condensation production is more stable.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of reference numerals:
The 1-condensation kettle; 2-alkali drips tank; 3-PH on-line determination instrument; The 4-switch board; 5-auto feed valve; The 6-by-pass valve control.
Embodiment
Below engaging accompanying drawing is described in further detail the utility model.Known in conjunction with Fig. 1, Profenofos condensation PH of the present utility model detects and adjusts automaton, comprise that condensation kettle 1, alkali drip tank 2, PH on-line determination instrument 3, switch board 4 and auto feed valve 5, be provided with PH on-line determination instrument 3 in condensation kettle 1, PH on-line determination instrument 3 is connected on switch board 4, switch board 4 also connects and controls auto feed valve 5, and the two ends of auto feed valve 5 connect respectively condensation kettle 1, alkali drips tank 2.By-pass valve control 6 is connected to alkali and drips between tank 2 and auto feed valve 5.
The course of work of this equipment is as follows: reaction mass, when condensation kettle 1 reaction, sets the PH range of control at automatic control cabinet 4, and PH on-line determination instrument 3 is measured PH within area requirement the time, and switch board 4 is controlled automatic valves in closed condition; When pH value, during lower than desired numerical value, PH on-line determination instrument 3 is measured and is fed back to switch board 4, and switch board 4 is controlled automatic valves and added liquid caustic soda, add on pH value in limited time, automatically stop adding.The use of this device greatly improves processing safety, stability and automatization level.And adopt online pH value to measure and automatic makeup adds the liquid caustic soda device and jointly controls, improved working condition, changed the people for the time control batch between mistake big-difference present situation, condensation production is more stable.
