How to Debug the Chemical Sludge Dryer

Chemical sludge dryer can bake 90% water content materials to finished products at one time. For the sludge drying process is easy to unite the characteristics of the block, change the general single-channel dryer material plate structure form, using a combination of self-cleaning device, greatly expanding the scope of application of single-channel dryer, not only can dry all kinds of sludge, but also can dry a variety of high viscosity materials.

1,Before installation, check whether the parts are intact and clean up the interior.
2,After installation in position before debugging should check whether the bearing seat has been injected grease, otherwise it should be filled with the appropriate amount of grease, generally choose No. 2 molybdenum disulfide compound calcium base grease or other high temperature resistant and other applicable grease.
3,Before installing rotary joints, read the "Instruction Manual" of rotary joints carefully and install them correctly to prevent damage to the gasket.
4,Heating or cooling medium inlet piping. Pressure gauge and pressure stabilizing device should be installed on the inlet line. A safety valve must be installed in front of the inlet to prevent the equipment from working under overpressure. The temperature of the heating medium must not exceed the rated operating temperature.
5,For the single-end configuration of the shaft end of the rotary joint in the installation should be noted that the surface within 200 mm of the end of the receiver into its cavity should be smooth, no holes, no rust, no slag, no scars, to meet the requirements of the sealing of the heating (or cooling) medium, and the size is appropriate. The same as double-ended rotary joints, the whole machine can be commissioned only after the test pressure does not leak.
6,Check and debug the gear drive or chain drive, so that it meets the mechanical transmission requirements.
7,Check the safety of the motor and electrical appliances. Tap the power switch of the motor, the motor and transmission parts should be free of jamming, and make sure the spindle is turned correctly (the tip should face forward when the paddle is rotating).
8,Start the motor, so that the equipment no-load operation, operation should be smooth, no abnormal noise. For with speed control device should be adjustable range of speed control, acceleration should be carried out slowly to check whether the speed control characteristics meet the requirements. No-load operation should not be less than 30 minutes.
9,Gradually heating or cooling, observe the operation, so that the heat source or cooling source to achieve the use of parameters. Equipment with cooling protection device must open the cooling water valve before passing steam. Gradually add materials, observe and check the drying of materials, and constantly adjust the amount of material added, the amount of heat (cold) source, the amount of material discharged and the speed according to the needs, and put it into normal operation after it reaches the design requirements.
