Continuous heat treatment device for fastener

Abstract

The invention discloses a continuous heat treatment device for a fastener. The continuous heat treatment device comprises a box body, wherein a heater is fixedly installed on one side in the box body,a heat exchanger is fixedly installed on one side of the heater, a water tank is installed on the side, away from the heater, of the heat exchanger, a water pump is fixedly installed on the side, away from the heat exchanger, of the water tank, a heat insulation plate is fixedly installed on the side, close to the top of the water pump, of the box body, a heating groove is fixedly formed in the top of the heat insulation plate, first telescopic rods are fixedly installed on the bottom side in the heating groove, a filter screen is fixedly installed on the top of the first telescopic rods, a conveying belt is fixedly mounted at the top of the filter screen, fans are fixedly mounted at the top of the conveying belt, through holes are formed in the two sides, close to the conveying belt, ofthe box body, and the through holes include a feeding port and a discharging port. The continuous heat treatment device for the fastener is simple and reasonable in structure and convenient to use, effectively solves the problems that most existing heat treatment devices are low in energy utilization rate and lack of cleaning of internal dirt, and has wide application and popularization value.

Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to a continuous heat treatment device for fasteners. Background technique [0002] Thermal treatment process generally comprises heating, insulation, three processes of cooling, has only two processes of heating and cooling sometimes. These processes are connected with each other and cannot be interrupted. Heating is one of the important processes of heat treatment. The heating means of metal heat treatmet are a lot, are the earliest to adopt charcoal and coal as thermal source, and then using liquid and geseous fuel. The application of electricity makes the heating easy to control without environmental pollution. These heat sources can be used for direct heating, but also for indirect heating through molten salt or metal, or even floating particles. When the metal is heated, the workpiece is exposed to the air, and oxidation and decarburization often occur (that is, the ...

AI Technical Summary

Problems solved by technology

[0003] Fasteners need to be heat treated during processing, and most of the existing heat treatment devices for fasteners still have the following deficiencies: 1. Lack of devices for utilizing waste heat in the heat treatment process, resulting in low energy utilization efficiency; 2. Lack of automatic cleaning of dirt The dirty device makes cleaning inconvenient and increases the labor intensity of the staff; therefore, we improve this and propose a continuous heat treatment device for fasteners
