Description

Circulation tank for inhibiting foam of cleaning agent of strip steel continuous cleaning unit

Technical Field

The utility model relates to continuous strip steel cleaning equipment, in particular to a circulating tank for inhibiting foam of a cleaning agent of a continuous strip steel cleaning unit.

Background

Production units such as continuous annealing, hot galvanizing and the like are equipped with a pre-cleaning function, and rolling oil and residual iron powder on the surface of a cold-rolled steel sheet are cleaned, so that good conditions are created for subsequent annealing and galvanizing procedures.

The main component of the cleaning agent is NaOH, the cleaning agent has a stirring effect in the processes of heating, high-pressure spraying, circulating and the like, the cleaning agent can generate a large amount of foam along with strong stirring, the foam can influence the cleaning effect of a product in production, and simultaneously, a large amount of foam overflows from groove bodies such as a working groove and a circulating groove, the phenomenon can cause the pollution of peripheral equipment at a cleaning section and the deterioration of the working environment due to the long-term existence of the phenomenon, the consumption of the cleaning agent is increased, and the production cost is increased.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a circulating tank for inhibiting the foam of a cleaning agent of a strip steel continuous cleaning unit, so that the foam of the cleaning agent is broken in the circulating tank, and the foam of the cleaning agent is inhibited from being generated.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides an restrain circulation groove of belted steel continuous cleaning unit cleaner foam, includes cell body, outlet conduit, circulating pump, return water pipe, and the return water pipe is vertical to be stretched into to the bottom of cell body, and the bottom of return water pipe is equipped with the ascending water outlet return pipe of delivery port, and the water outlet return pipe stretches into to the water pressure cover in, and the bottom fixed connection of water pressure cover goes out on the bottom surface of cell body, and the top of water pressure cover is the arc and seals the top, is equipped with the square play water pressure release hole of a plurality of on the arc and seals the top.

The bending angle of the water outlet bent pipe is 150-180 degrees.

The water outlet pressure relief hole is square or rectangular.

The height of the water outlet pressure cover is 1000-1200 mm.

The top of the tank body is provided with a manhole.

Compared with the prior art, the utility model has the beneficial effects that:

1) defoaming is realized through physical action, and foam is controlled in the circulating tank, so that external environment pollution caused by overflow is avoided.

2) Other media are not added in the defoaming process, and the technological parameters of the cleaning agent are not changed, so that the stability of the production line process is realized, and the cleaning effect of the strip steel is ensured.

Drawings

FIG. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a cross-sectional view of the water discharge pressure cap.

Fig. 3 is a top view of the water outlet pressure cap.

In the figure: the device comprises a tank body 1, a water outlet pipeline 2, a circulating pump 3, a water return pipeline 4, a water outlet bent pipe 5, a water outlet pressure cover 6, an arc-shaped capping 7, a water outlet pressure relief hole 8 and a manhole 9.

Detailed Description

The following further describes embodiments of the present invention with reference to the accompanying drawings:

referring to fig. 1-3, a circulating tank for inhibiting foam of a cleaning agent for a strip steel continuous cleaning unit comprises a tank body 1, a water outlet pipeline 2, a circulating pump 3 and a water return pipeline 4, wherein a manhole 9 is arranged at the top of the tank body 1.

The water return pipeline 4 vertically extends into the bottom of the tank body 1, the bottom end of the water return pipeline 4 is provided with a water outlet bent pipe 5 with an upward water outlet, and the bending angle of the water outlet bent pipe 5 is 150-180 degrees.

The water outlet bent pipe 5 extends into the water outlet pressure cover 6, the bottom of the water outlet pressure cover 6 is fixedly connected to the bottom surface of the tank body 1, and the height of the water outlet cover is 1000-1200 mm. The top of the water outlet pressure cover 6 is an arc-shaped capping 7, and a plurality of square water outlet pressure relief holes 8 are formed in the arc-shaped capping 7. The water outlet pressure relief hole 8 is square or rectangular.

The device utilizes the action of external force to give certain pressure to the foam, so that the foam is broken under the action of pressure extrusion. The water outlet bent pipe changes the water flow direction from top to bottom into from bottom to top, so that the stirring effect of high-speed descending of liquid is reduced. Be equipped with out water pressure cover at return water pipe outlet, the effect of play water pressure cover is inside a water pressure cover with the foam control, and the foam can take place to break under the effect of pressure after internal pressure increases. When the foam is gathered and overflows through the water outlet pressure relief hole, the foam is damaged again due to the fact that the square hole is extruded in a shape different from the shape of the foam. Fundamentally reduces the problem of a large amount of foam generated in the circulating process of the cleaning agent.

In the above embodiments, it is obvious to those skilled in the art that the present invention can be modified and modified without departing from the principle of the present invention, and the modified and modified embodiments also fall within the protection scope of the appended claims. The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and their concepts should be equivalent or changed within the technical scope of the present invention.
