Description
Technical Field
The utility model relates to the technical field of decanter control, and particularly discloses a control device of a decanter of a sewage treatment device.
Background
With the national emphasis on ecological environment, the requirements on environmental protection are more and more strict. If the production sewage of an enterprise can not be discharged according to the standard regularly, the life and death of the enterprise and whether the water treatment facilities of the enterprise operate normally are directly related, and the survival and development of the enterprise are directly influenced. The water decanter is a device for removing clarified water regularly adopted by SBR technology, and has the main working principle that the electric push rod drives the water discharging device up and down to decant water, when the electric push rod moves downwards to a water discharging position, the electric push rod rotates the screw rod to cut off the lower limit cam control switch, the control power supply is cut off, and the electric push rod motor stops running. When the process allowable time is reached, the DCS gives a starting signal to lift and decant water to the upper limit, the cam control switch acts to disconnect the control loop, and the water decanter stops working. And starting a new cycle when the process allowable time is reached.
The conventional HYBS rotary decanter usually has faults, and researches show that the cam control switch in the decanter must be ensured to work to ensure the long-period safe and normal operation of the decanter. Because the cam control switch drives a plurality of groups of gears to carry out variable speed limit by rotating the screw rod through the electric push rod, the limit distance is not well adjusted, the gears are easy to damage, the limit switches of the upper cam and the lower cam are disabled, the motor drives the electric push rod to rotate all the time, the screw rod is worn out, and the decanter is scrapped. The main reasons for causing the water decanter to be damaged are the following four points: firstly, the quality of a limit switch is poor, and the action is not acted; secondly, a cam controller for controlling the limit switch is in contact with the limit switch for a long time to cause overlarge gaps and poor contact; thirdly, the speed-changing gear driving the cam controller is easy to break down; fourthly, the telescopic distance of the electric push rod is improperly adjusted, so that the limit switch does not act. Therefore, aiming at the defects that the traditional HYBS rotary decanter controls the upper position and the lower position of an electric push rod through a cam control switch, the application provides the control device of the decanter, which can effectively solve the technical problems.
