AI Technical Summary

Technical Problem

In traditional medium-frequency melting furnace smelting slag recovery devices, the bolt connection of the moving jaw plate is prone to loosening, which leads to an increase in the gap between the moving jaw plate and the moving jaw body, affecting the stability and service life of the equipment, and the installation method is cumbersome and time-consuming.

Method used

The design employs a tapered insertion fit between the locking pin and the positioning groove, combined with multi-dimensional fixation of the sliding pin and positioning components. The stable connection of the moving jaw plate is achieved through the meshing transmission of gears and toothed plates, preventing loosening and detachment, and simplifying the installation process.

Benefits of technology

Maintaining a stable connection between the moving jaw plate and the toggle plate seat in high-frequency vibration environments reduces the risk of detachment, simplifies the installation process, extends the service life of the equipment, and reduces maintenance costs.

Abstract

This utility model relates to the field of smelting slag recycling technology and discloses a medium-frequency smelting furnace slag recycling device, including a jaw crusher body and an elbow plate seat movably installed inside the jaw crusher body. The elbow plate seat has a sliding groove and a placement groove on its surface, and a positioning groove at the bottom of the sliding groove. A movable jaw plate is fitted to the surface of the elbow plate seat, and a slot is provided on the back of the movable jaw plate. A sliding column is inserted into the slot, and a locking pin is fixedly connected to the surface of the sliding column. This utility model uses the conical insertion of the locking pin into the positioning groove, the limiting of the sliding column, and the gear meshing transmission of the positioning component to allow the positioning plate to synchronously and in reverse engage with the locking groove. Combined with the longitudinal limiting of the square column, a multi-dimensional fixing system is formed, improving the connection strength between the movable jaw plate and the elbow plate seat, reducing the risk of detachment. It eliminates the need for bolt clamps, saving time and effort during installation. The protective plate prevents wear from slag, and the modular design facilitates parts replacement, reducing maintenance costs.
