in the lungs recycled aggregate concrete manufacturing equipment wash water neutralization device

摘要

The present invention relates to a device for neutralizing the waste wash water recycled aggregate concrete production apparatus, neutralizing the washing water (pH 7 0.5) by using a surface foreign matter greatly improves the cleaning and removal of the recycled aggregate additive effect is significantly increased as well as the water pollution prevention and characteristics such as excellent economic efficiency can greatly reduce the use of a coagulant have. ; [Configuration] ; 1 order settling chamber storing waste concrete playing the enemy discharged from a pipe connected to the raw water tank of aggregate production device (11) is provided with a first primary sedimentation chamber 11 from the overflow (over flow) that can be used as a secondary raw precipitation chamber 12, which is again a storage tank (10) and; PH measuring device 13 and check the pH value of the raw water to pass in the secondary sedimentation chamber (12) to a control unit 30; And a pump 14 for pumping raw water of the secondary settling chamber 12 in the neutralization tank (15); The pH measurement apparatus according to raw water pH value of the secondary sedimentation chamber (12) is checked by a 13 Heritage (H ₂ SO ₄ ) in the tank 16 by discharging the stored legacy q.s. solenoid valve 17 and the legacy tank 16 is controlled by the neutralization tank 15 to be fed into the control unit (30); Stirring the raw water supplied from the legacy and the secondary sedimentation chamber (12) supplied from the legacy tank 16 to neutralize to pH 7 0.5 neutralization tank levels 15 and; The neutralization tank 15. The inside of the raw water check whether the neutralization to the desired pH value to pass to the control unit 30. Control unit 30 is neutralized reaction tank 15 to maintain the interior of the raw water with a neutral pH value constant and pH measuring apparatus 18 from time to time to be able to control the solenoid valve 17 to control the input of the abortion; Pump 19 and for supplying the neutralized raw water to neutral with deionized water tank 20 in the neutralization tank (15); Neutralizing the reaction tank storing the deionized water supplied from the (15), and is characterized in that the pump of the waste recycled aggregate concrete production device (P2) is connected consisting of deionized water tank 20 to be neutral as to enable the delivery of each line.
