Description

Sand blasting device for production and processing and early warning method thereof Technical Field The invention relates to the technical field of metal surface sand blasting, in particular to a sand blasting device for production and processing and an early warning method thereof. Background The traditional rotary disc type sand blasting device is widely applied to the field of surface treatment of heavy materials, and realizes uniform sand blasting on round or regular workpieces by rotating a rotary table for bearing the workpieces and matching with a fixed or simply movable sand blasting nozzle. However, when such devices are used to process square sheet materials, the inherent mode of operation exposes significant drawbacks. Since the sandblasting track is generally annular or spiral with the center of rotation as the center, for square plates with protruding four corners, to ensure the processing quality of edges, especially corner areas, the sandblasting flow to the outside of the plate boundaries where it is required to cover, resulting in direct and continuous erosion of the circular rotating base below by the high-speed abrasive. The long-term unexpected erosion not only can seriously damage the surface precision and structural integrity of the rotating base, shorten the service life of the rotating base and increase the maintenance cost of equipment, but also can influence the stability of the placement of the plate due to the surface damage of the base, thereby leading to uneven processing quality. Therefore, a technical solution that can be intelligently adapted to square plate processing and effectively prevent the rotating base from being eroded by sand blasting is needed. Disclosure of Invention The invention aims to provide a sand blasting system for production and processing, which is used for solving the problem that the emission does not reach the standard due to no desulfurization and denitrification treatment link in the existing emission treatment of the flue gas of an ore smelting furnace.

On the other hand, the embodiment of the application provides an early warning method of a sand blasting device for production and processing, which comprises the following steps: Under the condition that the sand-blasted plate is a square plate, acquiring a square plate size parameter input by an operator on a control panel, wherein the size parameter comprises a length value, a width value and a thickness value; calculating a height value between the upper surface of the square plate and the nozzle based on the thickness value, and scheduling a corresponding first effective sand blasting diameter and overlapping degree threshold range in an operation parameter comparison table based on the height value and the initial pressure value; If any overlapping degree value does not exist in the overlapping degree threshold range so as to meet the single air pressure sand blasting requirement, and the sand blasting pressure supply value needs to be increased, triggering excessive sand blasting early warning of the edge so as to prompt an operator that the edge of the square plate has an overpressure sand blasting risk; And generating a corresponding sand blasting path based on the square plate size parameter after the operator confirms that the overpressure sand blasting operation is performed. Optionally, when no overlapping degree value within the overlapping degree threshold value meets the requirement of single air pressure sand blasting and needs to increase the sand blasting pressure supply value, the method includes: Calculating the difference between the length value and the width value, recording the 50% difference as a first difference, and calculating the diagonal length of the square plate; Determining a first coverage amount of a first effective blasting diameter based on the first difference and the first effective blasting diameter, wherein the first coverage amount is a minimum value that the lengths of the plurality of first effective blasting diameters after being transversely arranged are larger than the first difference under the condition that the plurality of first effective blasting diameters are not overlapped; Correcting the transverse arrangement length of a plurality of first effective sand blasting diameters based on the minimum overlapping degre
