2.The chamber is composed of insulation board assembly structure, can minimize heat wastage,and eliminate thermal stress
3.The panel material is galvanized steel plate, and the outer wall is painted with color steel plate
4.The total thermal insulation layer of curing drying chamber is 100mm, and the end of drying chamber is equipped with maintenance door, so as to facilitate the maintenance of the equipment in the future
5.The heating system adopts the indirect heating method of gas. 
6.The gas in the furnace is continuously heated by the external heat exchanger under the guidance of the high temperature fan, so that the temperature in the furnace rises or keeps constant temperature
7.In the circulating heating system engineering, a new air supply air outlet and exhaust gas pipeline are set up to keep the moisture content and exhaust gas content below the standard requirements, so as to ensure the drying quality of the products
8.The hot air circulation fan adopts the air cooling built-in type, the circulation fan adopts the special high temperature and low noise centrifugal fan, and the fan impeller, the main shaft and the bearing are all specially processed
9.The furnace temperature is controlled by PID digital display, automatic temperature control,and temperature alarm function
10.In order to prevent the exterior surface of the cracking fume pollution chamber generated during the powder curing process, the inlet and outlet of the drying chamber are closed to set the workpiece into and out the profiling door

Overhead chain conveyor:
The suspension conveyer includes driving device,tensioning device,chain,straight rail,bending rail with various angles,inspection rail,telescopic joint,lubricating device,various kinds of rack and hanger
The driving device adopts linear drive,and it is equipped with overload protection mechanism
The tensioning mechanism adopts the heavy hammer tensioning,and the load can be adjusted arbitrarily by the heavy hammer
The chain adopts universal bearing wheel chain
The conveyor is equipped with inspection track,temperature expansion joint and automatic lubrication device
The conveyor runs smoothly, reliably, without crawling and clamping,meeting the requirements of the smoothness of the conveying device when the powder is sprayed

Electronic control system:
The temperature control in the drying line of the production by digital display instrument
All low voltage components are either Schneider or Siemens to ensure their reliability and sensitivity
All motors are equipped with air switch,thermal relay protection system,which can effectively overload,short circuit,open circuit and other automatic protection
The design, manufacture and installation of electrical equipment are in line with the requirements of the relevant national standards
The electric control system includes: control cabinet, wire, cable, threading pipe
