Abstract

The automatic slag blocking device of the descaling box comprises a rolling shaft, a steel rope, a slag blocking door, a counterweight and a cylinder, wherein the rolling shaft is fixed above the box body, the cylinder is connected with the counterweight through the steel rope, and the slag blocking door realizes up-and-down motion through the rolling shaft. Install one set additionally at descaling box entry the utility model discloses pushing off the sediment device, can keep off the iron scale that produces along with the high pressure water at descaling box, stopped the iron scale and splashed everywhere, eliminated the risk that the iron scale scalded to passing pedestrian, object strike and conflagration.

Description

Automatic slag blocking device of descaling box

Technical Field

The utility model belongs to the technical field of the metallurgy, a can block the inside iron scale that splashes along with the descaling water of descaling incasement portion, reduce the automatic shelves sediment device of iron scale scope that splashes.

Background

In the production of wide and thick plates in a steel mill, descaling box equipment generally adopts three rows of chains to control iron scales (figure 1) which are splashed along with high-pressure water, and has the defects that the iron scales cannot be completely blocked, when the high-pressure water strikes a steel plate, a large amount of iron scales are splashed everywhere along the direction of an inlet, the splashing range is wide, the iron scales are easy to accumulate at peripheral equipment, and meanwhile, the descaling box equipment is not beneficial to safety production due to safety risks of scalding of passing pedestrians, striking objects, fire disasters and the like.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an automatic pushing off slag device of descaling box to solve the problem that the scale splashes everywhere in the descaling box, eliminate equipment and personnel's potential safety hazard.

The utility model provides a technical scheme that the problem adopted:

the automatic slag blocking device of the descaling box comprises a rolling shaft, a steel rope, a slag blocking door, a counterweight and a cylinder. The roller is fixed above the box body, the cylinder is connected with the counterweight through the steel rope, and the slag blocking door realizes the up-and-down motion through the roller, the steel rope and the counterweight.

The automatic slag blocking device is additionally arranged at the inlet of the descaling box, when a steel plate runs into the descaling box, the slag blocking door is automatically controlled to be opened according to an electric signal by utilizing the gravity of the slag blocking door and a counterweight and the auxiliary force of the cylinder, and the slag blocking door is automatically opened after the steel plate is output from the descaling box.

The utility model has the advantages that: install one set additionally at descaling box entry the utility model discloses pushing off the sediment device, can keep off the iron scale that produces along with the high pressure water at descaling box, stopped the iron scale and splashed everywhere, eliminated the risk that the iron scale scalded to passing pedestrian, object strike and conflagration.

Detailed Description

The following further describes the embodiments with reference to the drawings.

As shown in fig. 3 and 4, the automatic slag blocking device of the descaling box comprises a roller (1), a steel rope (2), a slag blocking door (3), a counterweight (4) and a cylinder (5), wherein the roller (1) is fixed above the box body, the cylinder (5) is connected with the counterweight (6) through the steel rope (2), and the slag blocking door (3) moves up and down through the roller (1).

Fig. 5 and 6 show: the working process of the automatic slag blocking device of the descaling box comprises the following steps: when the steel plate (6) runs into the descaling box, the heat detection equipment detects the signal of the steel plate (6), immediately sends a signal to the air cylinder (5), and the air cylinder (5) moves to an extending state along with the rolling shaft (1) and the steel rope (2). Because the gravity of the slag blocking door (3) is slightly larger than that of the counterweight (4), the slag blocking door (3) freely falls to a working position, namely the slag blocking door (3) is at the lowest position. The descaling nozzles (7) spray high-pressure water to the upper and lower surfaces of the steel plate (6) to carry out a descaling process. When the steel plate (6) continues to operate until the detection signal of the steel plate (6) disappears, the cylinder (5) automatically moves to a retraction state by utilizing the spring, and at the moment, the gravity of the slag blocking door (3) is slightly smaller than the sum of the gravity of the counterweight (4) and the spring force of the cylinder, so that the slag blocking door (3) returns to the original stop position, namely the highest position of the slag blocking door (3).

Claims

1. Automatic slag blocking device of descaling box which characterized in that: comprises a roller (1), a steel rope (2), a slag blocking door (3), a counterweight (4) and a cylinder (5); the roller (1) is fixed above the box body, the cylinder (5) is connected with the counterweight (4) by the steel rope (2), and the slag blocking door (3) realizes the up-and-down motion through the roller (1).
