Abstract
The utility model discloses an air floatation device capable of automatically controlling and regulating air dissolved water volume. The air floatation device comprises an air compressor, an air dissolving tank, an air floatation tank, an air dissolved water pump and a PLC (Programmable Logic Controller), wherein a turbidity meter is arranged in the air floatation tank, a driving motor of the air dissolved water pump is a variable-frequency and variable-speed motor, the turbidity meter transmits metered data to the PLC, and the PLC gives an instruction to regulate the rate of revolution of the variable-frequency and variable-speed motor of the air dissolved water pump. According to the air floatation device, the turbidity meter is mounted in the air floatation tank, so that the increase/decrease of the air dissolved water volume can be effectively controlled in time according to the turbidity of wastewater, the quality of outlet water can be basically kept consistent, the efficiency is increased, and the cost is reduced.
Description
Technical field
The utility model belongs to environment-protective water treatment and purification equipment technical field, is specifically related to a kind of air-floating apparatus of self controllable adjusting dissolved air water amount.
Background technology
At present, in the air supporting that environmental protection equipment uses, air supporting utilizes dissolved air water pump that 30% to 50% recirculation water is injected in dissolving and becomes dissolved air water with the air mixed of compressing into from air compressor machine.So the number of dissolved air water be fix or to pass through manually-operated gate regulating pondage size by rule of thumb.The water quality of sewage fluctuates often, and in the time that turbidity changes, we need to strengthen to reflux and strengthen dissolved air water amount.With manual regulation valve size control dissolved air water amount often do not catch up with water quality fluctuation change.
Summary of the invention
The utility model object is to overcome problems of the prior art, and the device of the molten tolerance size of a kind of self controllable increase is provided.
The purpose of this utility model is achieved by the following technical solution: a kind of air-floating apparatus of self controllable adjusting dissolved air water amount, comprise air compressor machine, dissolving, air flotation pool, dissolved air water pump, it is characterized in that: also comprise PLC controller, in air flotation pool, be provided with a turbidimeter, the drive-motor of dissolved air water pump is frequency control motor, turbidimeter is by the data transmission of surveying to PLC controller, and PLC controller sends instruction and regulates dissolved air water pump frequency converting speed regulating motor speed.
The beneficial effects of the utility model: the utility model is equipped with a turbidimeter in air flotation pool, can control according to the turbidity height of waste water the increase and decrease of dissolved air water amount, can control timely and effectively, effluent quality is consistent substantially, improve efficiency, reduced cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the air-floating apparatus of self controllable adjusting dissolved air water amount of the present utility model, comprise air compressor machine 1, dissolving 2, air flotation pool 3, slag scraper 4, dissolved air water pump 6, also comprise PLC controller, in air flotation pool 3, be provided with a turbidimeter 5, the drive-motor of dissolved air water pump 6 is frequency control motor, and turbidimeter 5 is by the data transmission of surveying to PLC controller, and PLC controller sends instruction and regulates dissolved air water pump 6 frequency control motor rotating speeds.
When work, be arranged on turbidimeter 8 in air flotation pool by the turbidity of sewage data transfer measuring to PLC controller, after PLC controller analysis contrast, send instruction and regulate the size of the dissolved air water pump 6 frequency control motor control water yields, thereby realize the increase and decrease of dissolved air water.
