AI Technical Summary

⚠Technical Problem

During the sintering process of existing polytetrafluoroethylene (PTFE) pipes, lifting tools are required when removing and cooling the pipes at high temperatures. This operation is inconvenient and frequent, affecting the ease of use.

⚗Method used

The design employs a horizontal sintering furnace combined with a roller conveyor and a cooling tunnel. High-temperature sintering is carried out using guide wheels and resistance wires. During cooling, the temperature is gradually reduced through multiple sets of water tanks and spray heads to avoid sudden temperature drops and simplify the pipe movement process.

🎯Benefits of technology

This technology enables convenient removal and cooling of high-temperature pipes, avoids the hassle of hoisting, improves ease of use, prevents surface cracking caused by sudden temperature drops, and further enhances the convenience and safety of operation.

Abstract

This utility model discloses a sintering device for polytetrafluoroethylene (PTFE) pipes, including a sintering furnace and a roller conveyor. The roller conveyor is installed on one side of the sintering furnace, and a cooling tunnel is fixedly installed on the top surface of the roller conveyor. A water tank is fixedly installed on the top surface of the cooling tunnel. A water pump is connected to one side of the water tank via a pumping pipe, and a water delivery pipe is connected to the output end of the water pump, extending into the cooling tunnel. A branch pipe is connected to the surface of the water delivery pipe. Beneficial effects: This utility model features a horizontal sintering furnace. Workers can place the PTFE pipe blank between guide wheels. After closing the sintering furnace, the resistance wire can be activated, and the PTFE pipe blank is sintered using the heat from the resistance wire. After sintering, the furnace door can be opened to push the PTFE pipe out of the sintering furnace, facilitating the movement of the PTFE pipe, eliminating the hassle of hoisting, and improving ease of use.
