Pigment special belt drier is designed by our plant developed products, professional for a variety of material drying paint industry, successful instead of using oven drying process. The application range of this machine is wide, the quality indexes of the product higher drying, but also greatly save manpower, material and energy, dry pigment automation, continuous stepped pace, is a novel efficient. Energy saving type dryer.
Material by screw extrusion mechanism into strips, even into the pigment special belt dryer mesh belt. Network with 16~20 stainless steel net, the adjustable frequency and rotating device driver network with mobile box is uniform in the dryer, the, two road cycling wind on the material stream through. Air circulation through the fan, heater, composed of a hot air distribution plate materials on heat exchange drying. In the cycle process, the air wet gas content of the wet discharging port, regulating valve, exhaust fan exhaust. On the other part of the gas is heated circularly by the circulation fan, in order to fully utilize the heat, a small amount of leakage to the bottom material, by cleaning up the system to the spiral discharging exhaust, to ensure that the dryer running.
Paint drying generally adopt two belt dryer used in series, which is divided into feeding and discharging. The feeding section as the materials with a high moisture, poor permeability, so the material thickness, fast running speed, drying temperature is high. According to the material properties, temperature, in general about 120 because the material most of the water in the feeding section off, into the outlet section of the material moisture permeability or teach less, material, and moisture content of material property is mainly the internal moisture required dry for some time, so the net belt running should be put in the position of the material layer is slow, thickening. According to the material properties, drying temperature should not exceed the material bearing temperature. Drying cabinet temperature measuring point control the vapor passes through the electromagnetic valve of quantity, so as to achieve the purpose of controlling the temperature. The two section drying, better play to the performance of belt type dryer. Higher moisture after drying material uniformity, color, luster, strength and drying equipment drying product quality
Pigment special belt dryer before the inspection work:
Before starting, check the fan power supply connection is reliable, the fan is turned to the right. Heater air intake before, should first steam drain valve on the manifold open, drain the condensed water in the pipeline, and the bypass valve is open, direct steam pipeline rust away impurities, and then close the bypass valve, then let the trap began to work, and shall check the heater, steam trap, the electromagnetic valve is working properly. Check whether the extruding machine speed to meet the requirements, the material box has no other impurities. Especially the extruding machine after use if a plurality of residue buildup in the machine, must rinse with water after starting, there may not be any metal objects into the body material box to avoid rolling bad drum.
All of the above all meet the requirements can be formally feeding operation
Boot
Open the power to make all parts of the machine in normal operation. General running for 10 minutes after the start of feeding, boot time by following the sequence of operation.
1 open the steam inlet valve (oven temperature measuring electromagnetic valve control)
2 open the circulating fan (note the motor in normal operation by station opened)
3 open the wet exhaust fan (note the motor in normal operation by station opened)
4 open the drying chamber belt conveyor frequency controller button, turn to normal (when the temperature reaches the specified requirements)
5 open the extruding machine, the speed from slow to fast (according to the test material thickness setting speed)
6 open the bottom cleaning system (discharging screw conveying mechanism)
7 open the pulse controller (set the pulse times and should always clean up the material box material)
8 open finished charging system (to ensure smooth feeding)
Stop
Shutdown according to the following sequence of operation:
1 closed feeder, material feeding machine shutdown to clean up.
2 close the steam valve, should in general be in feeding, discharging network no material is then off steam.
3 closed circulating fan: start from feeding by station shutdown.
4 close the wet exhaust fan: start from feeding by station closed.
5 close the mesh belt drive variable frequency controller.
Close the valve at the bottom of the cleaning device 6.
7 the material all cleaned up, turn off the power. |
