Specific implementation mode
The utility model is further described below in conjunction with attached drawing and specific embodiment.
It is a kind of efficient alloy baking device isometric drawing as shown in Figure 1.
The device include alloy feed bin 1, alloy bin bottom intermediate arrangement have feed bin cutting plate 4, alloy feed bin 1 two
It is provided with shut-off valve 14 on 3 pipeline of gas three-way of burner 2, burner 2 there are two side is symmetrical, shut-off valve 14 can facilitate
Overhaul of the equipments.Two-way coal gas branch converges to main gas pipe road 5.What main gas pipe road 5 connected has gas proportion regulating valve, cut-out
The devices such as valve, pressure transmitter, flowmeter, these devices Hui Ju be connected in PLC control cabinet.The 1 inside installation of alloy feed bin
Have temperature measuring equipment.That is installed on burner 2 has igniter 13 and flame detector.Burner 2 is by gas three-way 3 and branch's coal
Air pipe connects, and the combustion tube upper surface of the other end and burner 2 is attached.Ring flange, a ring flange is arranged in combustion tube
It is docked with 1 bolt of alloy feed bin.It is provided with several automatic Air Adjusting holes 11 on burning tube wall.
The connection of 3 upper end of gas three-way is a set of path transfer device.The path transfer device includes being set on gas three-way 3
The path transfer nut 6 of end cap is arranged intermediate sealing nut 7, through the path transfer screw rod 8 among path transfer nut 6, and screw rod upper end connects
It is connected to path transfer handwheel 9, lower end is connected with stabilizer 10.
1 arranged beneath of alloy feed bin, one vibrating screen 12.
The stop valve of coal gas main line, power grid goes offline, gas pressure fluctuates big situation, chain control cabinet can play
Quick defencive function.
, there is flame-out, cutoff in flame detecting device, the case where can detecting flame combustion in real time, and alarm at once is sent out
Feedback signal executes defencive function to switch board and closes coal gas fast cut valve.
What is be arranged inside the apparatus for baking is made of thermocouple, compensating wire, digital display, thermometer, is capable of the inspection of overall process
Survey the temperature in stove.
