A split type ultrasonic sludge interface meter is used as the sludge interface meter and can be installed in a way that a probe is submerged, the top part faces upwards and the overhead height is adjusted until the upper surface of the probe is floated to the floating mud layer top. An ultrasonic solid suspended matter concentration meter is used as the sludge concentration meter, and can be installed in a way that the probe is submerged. The efficient automatic air-floating mud scraper control device of the air floating tank is suitable for separating mud and water of the air floating tank, capable of effectively controlling the air floating tank outlet mud concentration and capable of improving the efficiency for pumping the sludge by a sludge pump.
Description
Technical field
The invention belongs to a kind of sewage disposal mechanical automation control techniques, specifically in a kind of sewage disposal mud-water separation process, be used for striking off on the flat flow type air-float pool mud scraper operation automatic control device of mud scum.
Background technology
In the sewage treatment process method of mud-water separation have a variety of, as: gravitational settling method, By Bubble-floating Method, mechanical process etc., wherein By Bubble-floating Method is a kind of typical technique.Its method is to pass into a large amount of micro-bubbles in water, and the solid particulate in microbubble and the water is adhered to, and forms density less than the band gas flco of water, under the effect of buoyancy, floats to the water surface and finishes solid-liquid separation.The method is used for the history in existing more than 100 years of ore dressing, is used for the history in existing more than 80 years of water treatment, is used for concentrated existing more than the 50 years history of mud, replaces the research of second pond that the history in 20 years is also arranged.
Efficient air-floating (HeDAF, High-efficient Dissolved Air Flotation) belong to the improvement of traditional air-dissolving air-float (DAF), structure adopts utility model patent: ZL201120017942.2 " the activated sludge floatation concentrating unit of membrane biological reaction pool process ".This technology is with the gentle mixing pump that sucks simultaneously of water, finishing the solvability of gas-liquid two-phase in pump in the pressurization mixes, gas saturation can reach 100%, vapour-liquid ratio 10～30%, microbubble is less than 30 microns, daf efficiency is high, and energy-saving effect is remarkable, compares cost savings 30～40% with traditional air-dissolving air-float.This technology has been saved gas compressor, dissolving, the reflux pump of traditional air-dissolving air-float, molten gas release head and the complicated equipment such as Controlling System, and facility investment is few, and floor space is little, simple to operate, maintenance is few, and gas-solid ratio is low, and treatment capacity is large, reflux ratio is low, and dosage is few, cost savings.
Although have above-mentioned advantage, efficient air-floating does not still have to solve the at present operation control problem of all air supporting modes of all the time puzzlement, and namely existing air supporting mud scraper control method all can't satisfy the needs of automatically controlling air supporting mud extraction concentration by set(ting)value.In actual production, the pipeline of mud is carried needs the control sludge concentration, and the too high or too low pumping efficiency that all will cause of sludge concentration descends.The fairly large industrial experimentation in 1 year by a definite date finds that air supporting mud extraction concentration and Mud Layer thickness have preferably dependency.For present progress, efficient air-floating automatic control device of mud scraping machine and method need to be reformed.
The utility model content
The purpose of this utility model is in order to solve the problems of the technologies described above, to propose a kind of air flotation pool efficient air-floating automatic control device of mud scraping machine, by instrument monitoring Mud Layer thickness, thereby reaching the needs of automatically controlling air supporting mud extraction concentration by set(ting)value.
The purpose of this utility model is to realize by following technical scheme:
Air flotation pool efficient air-floating automatic control device of mud scraping machine, be provided with efficient air-floating pond and mud scraper electric operator, the air flotation pool flotation area is provided with the thickness of sludge interface meter monitoring Mud Layer, the air flotation pool mud-output trough is provided with sludge concentration meter monitoring mud extraction concentration, above-mentioned two kinds of instrument monitoring values are sent into PLC housing with Embedded Touch Screen by signal cable, the PLC housing be provided with the logical operation circuit module and mud scraper topworks sent open, the pilot circuit module of stop instruction.
Described sludge interface is counted split type ultrasonic sludge level meters, and mounting means is installed for the probe submerged, and the top is upwards adjusted outage and pushed up for probe upper surface to Mud Layer.
Described sludge concentration is counted ultrasonic solid concentration of suspension meter, and mounting means is installed for the probe submerged.
Advantage of the present utility model: can automatically control air flotation pool mud extraction concentration by set(ting)value, realize the effective control to air flotation pool mud extraction concentration, improve the efficient of sludge pumping mud, thereby greatly improved performance and the efficient of air flotation pool.
