[0041] In a specific embodiment of the explosion-proof dust removal grinding workbench system, the working principle and advantages of the explosion-proof dust removal grinding workbench system are as follows:

[0042] Place the workpiece to be polished on the rotating table 13. When the polishing equipment is used to polish the workpiece, the two manual rotating tables 13 on the polishing table can easily realize the rotation of the heavier workpiece, reducing the work intensity of the workers. When polishing the workpiece, dust with sparks may be generated. Before entering the explosion-proof dust collector, the dust gas without sparks is filtered by the fire-blocking net in the air outlet 14, and enters the dust collector. Under the action of the explosion-proof dust removal fan, the four flame-retardant filter cartridges are responsible for filtering the dust-containing gas to achieve the dust removal function. The clean air is discharged after being silenced by the exhaust silencer 5 at the top to reduce noise. The explosion-proof dust collector is equipped with a compressed air back-blowing cleaning device, which can back-blow the filter cartridge 22 to clean the filter cartridge 22.

The network interface for connecting the communication line and other reserved information data interfaces set up in the main controller enable it to realize functions such as remote status monitoring, remote diagnosis and remote troubleshooting, and other system detection functions. At the same time, it meets the use requirements of maintenance-free components of the explosion-proof dust removal polishing workbench system and the application of intelligent inspection technology of components, and reserves interfaces for subsequent systematic management and integration of equipment. The connection cable of the control system of the explosion-proof dust removal polishing workbench system adopts the explosion-proof wiring method of explosion-proof hose + galvanized steel pipe. The explosion-proof touch screen set up in the main controller realizes human-computer communication, and the various control actions required for system operation (including the start and stop of the dust removal fan, the opening and closing of the filter cartridge back-blowing cleaning device, and other control logic) are realized by the written PLC control program.

[0044] In summary, compared with the fixed tabletop of the existing grinding workbench equipment, the explosion-proof dust removal grinding workbench system adopts a rotary grinding workbench + explosion-proof filter cartridge dust removal system, which solves the problems of workpiece rotation, spark capture, filter cartridge dust collection, explosion-proof control, and PLC main controller control program modification, remote diagnosis and remote troubleshooting, avoiding the risk of dust explosion and fire caused by sparks generated by electrical components, reducing property losses and the possibility of personal injury. And by designing functions such as remote diagnosis, remote troubleshooting and remote program modification, it effectively saves after-sales service time, improves the user's equipment utilization efficiency, and effectively improves economic benefits.
