The automatic scale cleaning device can be used for cleaning a cooler for a hood type annealing furnace in cold rolling mills.
Description
The utility model belongs to cooler incrustation scale automatic on-line cleaning device, is specially adapted to the clear line of automatic on-line of cold-strip steel bell type annealing furnace cooler incrustation scale.
Present many water-cooled cooling effect of cooler are good, but at high temperature all can tie very thick incrustation scale at the inside pipe wall of cooler, not only influence cooling effect, and reduced the flow of water, reduce cooling velocity, influence the normal operation of equipment, for example in by computer-controlled full-hydrogen hood-type annealing furnace, because behind the cooler tube wall scaling, cooling water inflow reduces, and cooling velocity is reduced, and just produces the high and little alarm signal of flow of water temperature this moment, and stop to shunt accelerate cooling system automatically, cause the bell furnace underproduction even stopping production.Conventional treating method is to change cooler.It is long that but the replacing cooler not only takies the production time, and will expend substantial contribution.One six type cold rolling mill is used to change loss that cooler causes every year up to more than 3,000,000 yuan.
The purpose of this utility model provides a kind of cooler incrustation scale automatic flushing device of being made up of scale remover storage bin, water pump, non-return valve, ball valve, magnetic valve, Pressure gauge, flowmeter, water level controller, is used for the efficient cooler incrustation scale of removing automatically.
Another purpose of the present utility model provides a kind of control system of cooler incrustation scale automatic flushing device.
According to cooler incrustation scale automatic flushing device of the present utility model, the water pump that is connected with this scale remover storage bin by a scale remover storage bin, be connected on non-return valve, ball valve, Pressure gauge on the water pump, be connected with the cooler inlet by pipeline, cooler outlet connects a ball valve, and magnetic valve and flowmeter connect to the scale remover storage bin with pipeline, also is provided with water level controller on the storage bin, top is provided with water inlet pipe, and the bottom is provided with the outlet pipe of charged magnet valve.
According to cooler incrustation scale automatic flushing device of the present utility model, operation automatically under the control of the control system that a cover is made up of a series of switches and relay.
According to the utility model, when reaching useful life or cooling water flow, cooler do not reach when requiring less than setting or cooling effect, unload cooler intake-outlet joint, connect water inlet pipe and water outlet pipe of the present invention, a certain amount of quick descaling liquid is injected in the cleaning mixture storage bin, start pump, make cleaning mixture via non-return valve, ball valve and Pressure gauge, enter in the cooler by water inlet pipe, when flowing through cooling tube in the cooler incrustation scale of knot on tube wall cleaned, flow in the storage bin through ball valve, electric contact flowmeter and magnetic valve by cooler outlet then.
At the cleaning initial stage, because incrustation scale is serious in the cooler, therefore flow is less, prolongation along with scavenging period, flow increases gradually, when flow reaches the former design discharge of cooler, the circulatory system stops automatically, opens the discharge solenoid valve of scale remover storing box simultaneously automatically, and the cleaning mixture that will give up is discharged, the new water solenoid valve of the automatic connection of fluid level controller injects new water when having arranged in storage bin, when new water reach a certain height, fluid level controller stopped to inject new water automatically and starts pump simultaneously, new water is injected in the cooler wash, automatically stop after a few minutes cleaning, finish cleaning process.
