Advantageous effect：
The utility model structure novel, practical function, due to the valve in installing the utility model in valve output
Drainage device still can be used normally in the case where flashboard or spool damage not serious situation, effectively prevent caused by leakage
Data exception is monitored online in waste water；So that the replacement frequency of valve is greatly reduced, by replace the original 2-3 months it is primary till now almost
Without replacing, only environmentally friendly process saves about 100,000 yuan of purchase gate valve expense every year, and greatly reduces maintenance employee workload, protects
The smooth operation of production and environmental protection is demonstrate,proved；
Further set the drainage cavity of drainage mechanism to the cone to stand upside down, the top surface diameter 40- of the back taper
60mm, this set, which is more advantageous to, to be leaked out waste water and collects downwards, and capacity is sufficient, can effectively reduce waste water around drainage
The probability that mechanism directly flows out from the lower end of elbow and then causes waste water that data exception is monitored online；
It further uses drainage control mechanism instead solenoid valve, and is provided with valve opening and closing test section above elbow,
It realizes valve and drains the function of control mechanism self interlocking, not only reduce cost of labor, also precisely control drainage machine
The working condition of structure avoids the problem of untreated effluent caused by being delayed by manual operation cannot drain in time, can also be
Effectively drainage device is kept to be closed when processed waste water is normally discharged, keeps protecting drainage dress while normal production
It sets, and then extends the service life of drainage device；
It, can very easily control valve opening and closing inspection since one end of valve opening and closing testing agency is connected with height regulating rod
The height of mechanism is surveyed, and then the valve of various different heights can be suitable for, substantially increases the relevance grade of drainage device.
Due to being added to auxiliary purification portion, the waste water of drainage mechanism Small Amount simply can be individually handled, is avoided another
The process that waste water is drawn back wastewater disposal basin processing by outer addition drainage pump, can according to the level detection mechanism being arranged in drainage mechanism
The amount for implementing to grasp the degree and waste water to be drained of valve leakage further passes through the acid-base value being arranged in drainage mechanism
Testing agency is able to record the acid-base value of each waste water when leaking, and is convenient for big data analysis, can either grasp gate valve and exist
The probability leaked when soda acid difference, and the ingredient of tungsten ore waste water can be facilitated deciding on according to the waste water acid-base value of real-time display,
Elbow lower end can be imported again by assisting purification portion to minor amounts of waste water processing, after processing by drainage tube to discharge will not cause together
Data exception is monitored online in existing waste water, enormously simplifies program, further reduce due to valve leak influence production and
, also there is environmental protection in the problem of cost positive meaning.
