Technical requirements of platinum drying furnace and motor stator pre heated wire tunnel furnace

Date: August 17, 2020 [return]

1. Main structure: l8000 * w800 * h1800 ± 50 (mm) adjustable. High temperature resistant (200 ℃) double speed chain is adopted for conveying. The height of conveying roller surface is 800mm from the ground, the heating zone is 7000mm long, and 500mm is reserved for inlet and outlet respectively. Install the thermal insulation liftgate. The liftgate should be soft sealed. There should be no leakage of hot gas in the closed state. The liftgate is equipped with safety protection. The shell of the whole machine is made of cold plate with solid thickness of 2.0 mm. The surface is sprayed with plastic, and the bottom is equipped with adjustable foot cup and mobile foot cup. The sealing plate at the bottom of the equipment is detachable.

2. Heating part: the heating area is 7000mm, which is divided into five temperature zones, each section is 1400mm. One set of 0.37kw wind motor with 9-inch wind wheel is installed for each. The motor is directly connected with the flat key of the wind wheel. The material of the wind wheel is 304L, and the wind wheel is convenient for maintenance. The temperature sensor adopts double loop control (2 sensors), adopts l-u stainless steel fin electric heating tube, and adopts nichrome wire. Finally, the four air outlets are combined into one outlet.

 Tunnel drying furnace

3. Transmission part: 1 set of 750W gear reducer motor, motor brand: sew. The rated conveying speed is 400mm / min, the frequency conversion is adjustable, and the frequency converter is Siemens. A tray is sent out from the discharge port within 20 minutes. It has the function of frequency conversion and speed regulation, with digital display speed control panel. The height of double speed chain rib is 20 mm, and the width is 350.5-352.5 mm.

4. Electrical part: power supply 380V, three-phase five wire system. Siemens touch screen and Siemens PLC control system are used to support S7 communication to meet our communication needs. The furnace cover is equipped with independent control system, with Japanese Omron microcomputer intelligent temperature controller, with p.i.d self-tuning function; equipped with SSR solid-state relay output, the temperature range is adjustable from room temperature to 200 ℃, the instrument display error is ± 0.5 ℃, the furnace temperature difference is ± 5 ℃, the actual use temperature is 149 ~ 160 ℃, and other control appliances are imported Schneider Electric appliances or Omron Electrical control.

5. Action flow: start up and run double speed chain (400mm / min) drying channel heating - photoelectric detection at feed inlet - lifting of liftgate - closing of liftgate after feeding - repeated feeding - photoelectric detection in front of discharge door - lifting of liftgate - closing of liftgate after discharging - photoelectric detection of rear stop stop stop of rear stop photoelectric detection of front stop The follow-up control of front stop is one out and one in (continuous feeding if no discharge).

6. Surface treatment: hard chromium plating for machining parts, plastic spraying treatment for sheet metal parts and welding frame, color code: ral9002, Natural Color Anodizing of aluminum products.

7. PNP output of docking signal.
