Abstract
The utility model discloses an automatic furnace stopping device which consists of a programmable logic controller (1), a middle relay (2) and an alternating current contactor (3), wherein a signal output end of the programmable logic controller (1) is electrically connected with the alternating current contactor (3) of a furnace body through the middle relay (2). The automatic furnace stopping device has the advantages that the program can automatically switch off a main load power supply (electric heating), a main gas valve (gas heating) or a fuel main valve (oil heating) after a temperature control process is finished, so that energy consumption and energy loss are reduced, and the operation process is simplified.
Description
Technical field
The utility model relates to a kind of automatic blowing out device.
Background technology
At present, in gas furnace and heat-treatment furnace work engineering, gas furnace or heat-treatment furnace are quit work need to be by manually closing main power source or main air valve, and this process is more loaded down with trivial details.
The utility model content
The purpose of this utility model is exactly at present in gas furnace and heat-treatment furnace work engineering, gas furnace or heat-treatment furnace are quit work need to be by manually closing main power source or main air valve, the deficiency that this process is more loaded down with trivial details, and a kind of automatic blowing out device is provided.
The utility model is comprised of programmable logic controller (PLC), auxiliary reclay and A.C. contactor, and the signal output part of programmable logic controller (PLC) is electrically connected with the A.C. contactor of body of heater by auxiliary reclay.
The utility model has the advantages that: this device can finish rear autoshutdown master load power source (electrical heating), main main gas valve (gas heating) or fuel oil main valve (oil heating) in the temperature control process, thereby has reduced energy loss, has simplified operating process.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model is comprised of programmable logic controller (PLC) 1, auxiliary reclay 2 and A.C. contactor 3, and the signal output part of programmable logic controller (PLC) 1 is electrically connected with the A.C. contactor 3 of body of heater by auxiliary reclay 2.
The heat-treatment furnace type mainly is divided three classes, i.e. electric furnace, gas heating furnace and oily heating furnace.
The course of work: before the use, for dissimilar heat-treatment furnace, the signal output part of A.C. contactor 3 is electrically connected with the electromagnetic valve of gas circuit of electrically heated power switch, gas heating furnace and the pump switch signal input part of oily heating furnace, programmable logic controller (PLC) 1 inputs to A.C. contactor 3 by auxiliary reclay 2 with signal, the electromagnetic valve of gas circuit of electrically heated power switch, gas heating furnace and the pump switch of oily heating furnace are controlled, namely finished the furnace shutting down process of heat-treatment furnace.
