2.4 The device consists of pushing means pushing the lever, pushing head, slipper, pushing rod support rollers, blowing graphite means riser roots purge means purging mechanism rack, pushing gear and emergency push return the zoom lever devices and other components. Transmission form of the device for the motor through reducer and open gears, gear reducer is a horizontal double gear input shaft, an input shaft and the motor is connected to the other input shaft and the emergency hydraulic motor reducer + connection; Pushing rack drive rod pushing lever forward and backward movement, in order to prevent accidents in the forward end, backward end have an accident emergency stop limit switch, tooth and mechanical stopper triple safety measures. Elevation consider pushing the lever to adjust the balance of the pre-stay. Pushing the drive with frequency control. Pushing the lever stroke using an encoder for real-time measurements. Emergency Function: In order to be completed under the power of the state will push the zoom lever to exit, close the door, set up a station emergency diesel systems. The system is consistent with the formal structure of coal loading drive emergency system. L The device is also provided electric winch, once the motor, reducer or coupling damaged, you can push the zoom lever return by the rope.
2.5 open and close the door means the door opening and closing means and clear frame means sharing a mobile trolley unit, open and close the door all functions are realized by hydraulically operated through the use of a hydraulic cylinder with a displacement control during operation each stroke of the cylinder to control the whole operation. At the same time, the measured data is stored to the PLC, and real-time detection and memory, to maintain uniform operation. By using this system, you can overcome the changes in the coke oven and the oven door after heat deformation phenomenon, allows each coke oven door operation is very stable and uniform. Take car door by moving the cylinder along the gantry trolley track forward, and rotate the pickup head hanging door frame, forward pressure bolt, Timon, the removal of the door, close the door after the completion of the reverse action programs. Take the first door rotation is set via the rotary cylinder trolley completed.
2.6 door door cleaning device cleaning device is removed when the opening and closing door after door retreat limit position by pushing time, automatically sealing knife edge and the door lining brick cleaned, sealing knife edge cleaning is done by high-pressure water cleaning, to ensure tightness between the door and the frame, the control run gas, smoke. Clear action by a PLC controlled automatic door complete with interlock protection, will not collide with each other, while the clear door action and other agencies has interlock protection. Door cleaning device made clear door machine, hanging device, trolley, cylinder, high-pressure water system components.Clean door by hanging device connected to the trolley, trolley driven by hydraulic cylinders running back and forth in a fixed orbit, clear door body height position by hanging device, can be adjusted appropriately. When clear door work, cleaning the side of the car in the hydraulic cylinder, both sides of the screw cutter open, rearward on the back door, then run up and down the role of traction chain, milling to tar brick slot, while the door at the bottom of the hydraulic cylinder sweeper driven back and forth along the track running, milling to tar and tar brick scraper edge on the groove. The bottom surface of the drive side rotary cutter screw driven by the motor oil, and run up and down the side of the car is cleaned with a motor and a planetary gear brake completed. The device is designed with high-pressure water cleaning door system, using high-pressure water cleaning knife edge door to protect the door seals are not damaged machinery, improving the sealing effect of the oven door. High pressure water cleaning door system consists of the following components: a stainless steel high pressure tanks, high pressure pumping, high-pressure valve stations on both sides of the door, top, bottom, rotating high-pressure water gun, the overall pressure water system piping. Using the medium for life clean water, pumping high-pressure water outlet pressure ≥60 MPa, Flow ≥22 L / min. Valve stations using semi-enclosed structure, valve stations all valves, piping and other contact with water part made of stainless steel, with a long-term dry corrosion function. Rotary hydraulic motor driven by a rotary spray gun, speed 100 revolutions / min ~ 200 rotation / min.
