Summary Xinhai mechanical shaftless screw conveyor characteristics and performance
Zhengzhou Xinhai mechanical shaftless screw conveyor design, manufacture and installation to ensure that the transport equipment to meet the requirements of a high degree of work reliability and maintenance workload as little as possible to facilitate the use of inspection and maintenance features. Structure design of shaftless screw conveyor structure to ensure the circulation of materials handled, no blockage; in the course of their work with drainage. The shaftless screw conveyor mainly consists of a shaftless screw, a U-shaped spiral groove, a cover plate, a lining plate, an inlet and an outlet, a discharge port and a driving device. The material is input through a feed inlet, Outlet export. Driving device: The driving device is placed at one end of the screw conveyor. The motor reducer is directly connected with the screw driving shaft without the need of a coupling, which is convenient for disassembly and maintenance. The driving shaft can bear the load with simultaneous bending moment and axial pressing force . The drive (motor and reducer) adopts the structure of high-quality shaft-mounted reducer manufactured by SEW Corporation, which is flexible, stable and reliable, and has no abnormal noise. All gearbox joint surfaces and the input and output shaft seals will not leak . The drive motor is suitable for 380V, 3 phase, 50Hz, its protection grade is IP55 (outdoor type), insulation grade is F grade. The spiral blade of the shaftless screw conveyor is made of stainless steel cast by a special mold so that it has sufficient strength and rigidity and the surface of the blade is smooth and free from burrs and has a suitable rotation speed so as to effectively ensure that during feeding of the grid slag No entanglement of dirt and clogging occurs, and at the same time, the spiral blade will not deform under the condition of large conveying capacity. U-shaped spiral groove inside the wear-resistant lining is arranged in a semicircular shape, the arc is set to match the radius of the non-axis spiral body to reduce the excess gap to improve the delivery effect; wear-resistant lining with high wear-resistant nylon material for easy installation And replacement, long service life. U-shaped spiral groove made of stainless steel rolled, except for the feed opening, the rest along the spiral groove plus flat cover closed, the entire transmission process in a sealed tank to reduce noise and reduce odor emissions; in U-shaped groove at the bottom of the discharge port, and supporting drainage ball valve. Shaftless screw conveyor is not high-speed operation of the parts, so that transmission spiral wear low, energy-saving equipment, low noise. Shaftless screw conveyor easy to install, simply use expansion bolts to steel support can be fixed on the basis of the concrete, it can intermittent operation, but also 24 hours a day continuous operation. Shaftless screw conveyor with overload protection in the electrical design, to meet the shaft screw conveyor safe and effective operation. The electrical components that control the shaftless screw conveyor are included in the on-site electrical control box of the grille. The specific control requirements are found in the electrical control section of the grille. The signs on the equipment indicate the important parameters of the equipment such as the manufacturer's name, equipment name, model, date of manufacture and serial number in easy-to-read Chinese and fix it on the upper part of the equipment. The form, size and technical requirements of the product label conform to "Signs" (GB / T13306) requirements. Equipment parts anti-corrosion: stainless steel parts to clean up, and pickling passivation can be. Equipment Testing: Before the equipment is delivered from the factory, all parts of the equipment are accepted for inspection. The inspection items include appearance inspection, noise detection, reliability testing, testing of electrical equipment and testing of other items. Equipment at the factory to provide equipment factory inspection of qualified reports, product certification, the use of maintenance manuals, purchased parts of the warranty and certification. After the equipment is installed on site, it is run for 2 hours without load and with load. No-load operation for 2 hours: After the equipment is filled with lubricating oil (grease), it shall be manually operated and jogged at the same time to detect whether there is any obstacle in each space, and then to run continuously without any malfunction, without any abnormal vibration and noise during operation, The operation is over. With load operation: screw conveyor according to the actual delivery capacity with load operation, check the delivery effect to meet the requirements, after 2 days of continuous operation 24 hours a day without any mechanical failure as qualified.
