Drive protection type intelligent dosing system for sewage treatment

Abstract

The invention discloses a drive protection type intelligent dosing system for sewage treatment. The system comprises a control chip U1, a capacitor C4, a capacitor C5, a drive circuit, a signal input circuit, a power input circuit, a chip two-stage drive circuit, and a drive protection circuit. To be specific, a positive electrode of the capacitor C4 is connected with a THRES pin of the control chip U1 and a negative electrode of the capacitor C4 is connected with a GND pin of the control chip U1; a positive electrode of the capacitor C5 is connected with a CONT pin of the control chip U1 and a negative electrode of the capacitor C5 is connected with a GND pin of the control chip U1; the drive circuit is connected with the control chip U1; the signal input circuit is connected with the control chip U1; the power input circuit is connected with the signal input circuit; the chip two-stage drive circuit is connected with the control chip U1 and the power input circuit; and the drive protection circuit is connected with the drive circuit. The type of the control chip U1 is NE555. According to the system, the using effect and the intelligent level of the product can be improved; frequent manual operation is avoided; the manpower resource looses are reduced; and the sewage processing effect of the enterprise is improved further.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and specifically refers to a sewage treatment protection-driven intelligent dosing system. Background technique [0002] With the development of society and the deterioration of the environment, environmental protection has reached the point of no delay. In order to reduce the impact on the environment, today's enterprises will set up matching sewage treatment tanks to treat the sewage generated in the production process. In the process of sewage treatment, it is necessary to frequently add chemicals to the sewage treatment tank to improve the effect and efficiency of sewage treatment. In order to reduce the difficulty of adding medicine, most enterprises choose to use the medicine adding device to realize it. Pumped into the sewage treatment tank. However, the dosing mode of the existing dosing device is relatively simple, and its intelligence is poor. In actual use, it is necessary to pre-set...

Problems solved by technology

However, the dosing mode of the existing dosing device is relatively simple, and its intelligence is poor. In actual use, it is necessary to pre-set the dosing amount and the adding interval time, and it will work strictly according to the preset dosing amount and dosing time. Working at intervals, it is impossible to adjust the amount and time of adding chemicals according to the specific sewage conditions. When it is necessary to adjust the amount and time of adding chemicals, the operator needs to adjust the equipment on site. Adjust the equipment 5-7 times a day, which greatly wastes human resources
