AI Technical Summary

Technical Problem

In the existing railway tunnel coal powder cleaning device, the filter replacement process relies on manual or mechanical arms, resulting in a slow replacement rate, high cost and susceptible to sensor signals in an electromagnetic interference environment, affecting the accuracy and response speed of the system.

Method used

An adaptive railway tunnel coal powder cleaning filter replacement device is designed, including an automatic replacement mechanism and a cleaning and recycling mechanism. The automatic replacement mechanism cooperates with the special-shaped groove and the S-shaped rotary plate to achieve accurate positioning and replacement of the filter; the cleaning and recycling mechanism cleans the mesh plate by double air flushing and brushing to realize the recycling of the filter.

Benefits of technology

It improves the accuracy and speed of filter replacement, reduces the overall cost of the device, avoids the risk of manual operation, and effectively avoids signal attenuation and misjudgment in an electromagnetic interference environment, improving the applicability of the device.

Abstract

The invention discloses a self-adaptive railway tunnel pulverized coal cleaning filter screen replacement device, which relates to the technical field of filter screen replacement, and comprises a cleaning box, an automatic replacement mechanism, a filter screen replacement mechanism and a control system, the device is used for self-adaptively triggering the replacement process in the pulverized coal cleaning process and automatically overturning and replacing a screen plate, through arrangement of an automatic replacement mechanism and mutual cooperation of a special-shaped groove and an S-shaped rotating plate, a new filter screen body and an old filter screen body are replaced, accurate positioning is achieved through a mother magnet ring and a son magnet ring, and the replacement efficiency is improved. A U-shaped groove in the special-shaped groove extrudes a convex block of a convex block rotating disc, the convex block rotating disc and a rotating rod can be driven to rotate by a half circle, so that an S-shaped rotating plate rotates by a half circle, a servo motor is turned off in the rotating process, the convex block rotating disc is prevented from generating displacement due to rotation inertia, and the replacement accuracy can be further improved; therefore, the replacement accuracy and speed are ensured while the cost is reduced.
