Differential pressure puffing machine operating procedures

Expanding machine operating procedures

Expanding machine operating procedures a. Before starting and after the shutdown of the precautions 1, check the parts, especially the sections of the expanding chamber of the connecting screws, ground bolts, motor seat and frame connecting bolts, expanding chamber and the frame of the bolt connection, there shall be no loosening phenomenon. 2, manually so that the spindle rotates, this time, there shall be no clinking sound in the expanding chamber. 3, start the feeding Start the feeder, check its stepless high-speed performance, require normal operation. 4, check and clean up the water and gas lines before starting the machine. All filters need to be cleaned. 5, before starting the machine, check whether the wiring of the electric control part is correct, whether the motors are steering correctly, and whether the control is reliable. 6, after stopping the machine, you must wear high temperature gloves, quickly unload the discharging mold and clean it up immediately while it is hot. 7, after starting the main motor, you can start the main motor and start the puffing cavity. And start the main motor will be puffing cavity of the accumulated material empty. Corn puffing, should increase the soybean meal will be rinsed out of the cavity of the material. 7, pay attention to safety when unloading the machine, can not stand in front of people, to avoid the danger caused by the residual pressure of the puffing machine cavity. 8, the equipment is running normally, shall not be stopped. Second, boot 1, before starting the machine, check the fasteners, there shall be no loose phenomenon. 2, to ensure that the steam and water can be supplied normally. 3, to ensure that the power supply and electrical normal. 4, open the steam valve, preheat the puffing chamber, the temperature of about 100 degrees Celsius. 5, start to start the equipment: start the tempering device, start the feeding winch, tempering device at the exit of the material outflow, begin to tempering device in the addition of steam, when the material tempering, when the material tempering, the main motor, to the puffing machine cavity. Turn on the main motor, add a small amount of water to the puffing chamber, while feeding the material into the puffing chamber, when the material is extruded, adjust the puffing effect of the product and moisture and so on. Third, stop 1, the end of production (i.e., raw material warehouse still have material) need to stop, stop the order of: feeding winch, tempering device. Then wait until the electrical control cabinet on the host current indicator value becomes no-load current value, will be the main motor, oil pump motor stop, (corn puffing, should be in the first section of the puffing chamber of the bypass feeding port feed about 25 kg of soybean meal to clean the puffing chamber of the residual corn material, and then only to stop the main motor, to prevent clogging), followed by the end of the section of the puffing chamber quickly disassembled to clean up, clean up, the spindle and the After cleaning, the main shaft and the screw head wall coated with grease (feed grease), reloaded waiting for the next boot. 2, when you see the bin on the material level indicator indicates that the material level has reached the lowest level, start to do the shutdown preparations, at this time, do not stop the feed winch, tempering device, to be the host current drops to no-load current, stop the feed winch, the tempering device. Fourth, the order of operation 1, puffing soybeans, puffing chamber inlet end of the two sections of a single screw head, the outlet end of the three sections configured double screw head. First to the jacket with steam preheating expansion chamber to about 100 degrees, and the tail section of the expansion chamber on the screw plug tightened back to loosen 3-4 turns. Tighten the screw plug tightening screws to fix the screw plug can be fed through the control of the feed winch stepless high-speed mechanism, from slow to fast, feeding speed from small to large, to be soybean powder from the screw plug holes in the spray plus the cover that is into the normal production, the configuration of different aperture screw plugs, you can get different yields and fineness of soybean powder, through the configuration of different diameters of the conical pressure ring so that the fourth section (out of the end of the puffing chamber of the indication of temperature 130-140 degrees. It is recommended that the crusher used to crush soybeans sieve, its sieve hole aperture to the diameter of 3-4 is appropriate.

2, puffed powdered feed, puffing chamber of the extrusion screw all for the single screw head. Add steam to the jacket to preheat the expansion chamber to about 80 degrees. Into the puffing machine and steam evenly tempered powder, containing about 18% water, which must be completed in the feed tempering device. Through the stepless speed control mechanism to control the amount of feed from small to large, pay attention to the main motor ammeter readings shall not exceed the rated current of the host, beware of overload burned motor, puffing powdered material, through the configuration of different diameters of the conical pressure ring, so that the temperature of the puffing chamber of the discharge end of the temperature control to the appropriate degree. V. Repair and maintenance 1, maintenance will be the machine site control switch to the stop state. 2, equipment operation after each shift to clean up inside and outside, especially the puffing chamber shall not retain material, so as not to cool the lumps after the difficult to clean up. 3, puffing cavity spindle pulley should pay attention to frequent cleaning, shall not be too much ash, otherwise it will make the pulley imbalance caused by the vibration of the puffing chamber. 4, puffing cavity main bearings are lubricated with lubricants, the feed tempering device and its lubrication, the main bearing is lubricated by lubricant. Lubrication, feed tempering device and its transmission device bearing and other bearing parts using grease lubrication. 5, the main bearing must be regularly replaced with new oil, work 250 hours, all new oil. 6, other bearing parts, every 48 hours of work, injection of grease. 7, steam tempering device on the chain drive mechanism should be lubricated regularly. 8, reducer oil should be controlled in the calibration of the oil surface, work 250 hours after a new oil. 9, the reducer should be controlled on the oil surface, work 250 hours after a new oil. 10, the main bearing should be lubricated with grease. 11, the main bearing should be lubricated with grease. After 250 hours for new oil. 9, disassemble the screw head, shall not be re-tapped. 10, to often keep the puffer and its surrounding clean.

Operating procedures

One, before the start and after shutdown of the precautions

1, check the various parts, in particular, the various segments of the Expansion chamber of the connecting screws, ground bolts, motor seat and frame connecting bolts, expansion chamber and the frame of the bolt joint, there shall be no loosening.

2, manually make the spindle rotation, at this time there shall not be any friction sound in the expansion chamber.

3, start the feed winch, check its stepless high-speed performance, requires normal operation.

4, check and clean the water and gas lines before starting. All filters need to be cleaned.

5, before starting the machine, check whether the wiring of the electric control part is correct, whether the motor steering is correct and whether the control is reliable.

6, after stopping the machine must wear anti-temperature gloves, quickly remove the discharge mold, and immediately clean up while hot. And start the main motor will be puffing cavity of the accumulated material empty. Corn puffing, should increase the soybean meal to rinse the cavity of the material.

7, pay attention to safety when unloading the machine, can not stand in front of people, to avoid the danger caused by the residual pressure of the puffing chamber.

8, the equipment is running normally, do not arbitrarily stop.

Two, start
