2. General Description

The furnace is devided into four major sections: Furnace Body, Atmosphere Control System, Temperature Control System and Drive System.  

2.1 Furnace Body Design

Please see Table 1 and Figure 1 for detailed layout of the furnace structure.

Figure 1:Furnace Layout Drawing

2.2 Atmosphere Control System Design

5 compressed air inlet pipes, mass flow control range 12 - 120L/min,Please see Table 2 and Figure 2 for detailed layout of air inlet pipes.

Figure 2: layout of air inlet pipes drawing

2.3 The Design of Temperature Control System

A. Temperature Measuring: use K-Type thermocouple independent measuring and control on the temperature control point of each zone.   

B. Control Instrument:high precision intelligent temperature controller, with PID parameter auto tuning, high temperature upper limit alarm, thermocouple failure and other protective alarm functions.

C. Heating Control System: for the heating control, grouped power supply by several alternating current contactors to reduce the instantaneous current impact to the electric fence to the equipment.

D. Control Mode:Solid State relay zero cross trigger mode.

E. Over Temperature Alarm: when over temperature occurred in some zones, over temperature alarm system in corresponding zones immediately send audible and visual alarm signal and meanwhile the heating of this zone is cut off, the buzzer sounds alarm.

2.4 Drive System Design

Drive Control uses the frequency converter drive frequency variable motor to control the speed by gear box. The speed is adjustable continually.

Belt conveyor device: to drive the driving and drived wheel through chain and sprocket wheel, and then generate the friction force by driving wheel and the belt drive the belt running. There is a belt deviation guide device on the both sides at the entrance and exit.

3. Optional Configure

3.1 Computer Control System

A.DCS control system, intelligent temperature controller, industrial computer monitor

Grading Login, Chinese and English UI

B. Multiple programs saving, easy to edit and application

C. Temperature display and alarm information in real time, data saving and printing

D. It also can provide the temperature calibration function in the chamber for adjusting process requirement.

3.2 Ultrasonic cleaning machine (cleaning mesh belt)

It can effectively clean the impurities and small particle on the belt to avoid product contamination.
