Annular grooves are arranged at two ends of the hanging bearing body, and sealing bodies are arranged corresponding to the positions of the annular grooves. Bosses corresponding to the annular grooves are arranged on the sealing bodies, embedded into the annular grooves, and tightly fixed at the two ends of the hanging bearing body through pressing rings. Sealing dustproof rings are arranged on the contact surfaces of the sealing bodies and the shaft body. The temperature-resistance dustproof intermediate bearing can effectively achieve material conveying of the tubular spiral conveying device, has compact structure, and effectively ensures a circulation section of materials. A temperature-resistance corrosion-resistance dustproof sealing structure is adopted between the bearing and an external pressing ring, bearing loss can be effectively reduced, sealing is tight, performance is reliable, and no material is blocked. The temperature-resistance dustproof intermediate bearing is simple in structure, reliable in sealing and capable of effectively prolonging service life.

Background technology
Catalyst plant is because the restriction of locus and the characteristic of material generally adopt small-sized tubular type helix transporting device.When the short range convey materials, the spiral middle part can not add underslung bearing, can guarantee that material transmits, and the phenomenon that gets stuck do not occur.When fed distance is long slightly, add under the temperature of charge condition with higher, be easy to generate screw shaft distortion etc., underslung bearing generally will be set up in the spiral middle part, can guarantee that material transmits, and the phenomenon that gets stuck do not occur.
Summary of the invention
The purpose of the utility model is to improve and innovate to defective that exists in the background technology and problem, provides a kind of width narrower, and spiral interrupts apart from little; Can effectively guarantee the circulation of material; The material latch up phenomenon can not take place, and adopt plain bearing, according to the catalyst feed characteristic; Can select the end seal and the side seal of different materials; The hermetically-sealed construction that adopts make material not with the bearing direct contact, seal perfect, reliable, the tubular type helix transporting device heatproof that guarantees the transmission shaft normal operation middle bearing that prevents dust.
The technical scheme of the utility model is a kind of bearing that is arranged on tubular type helix transporting device spiral middle part of structure; Comprise the axis body that is connected between two conveyor screws; The suspension bearing body that is used to support and be located on the axis body and be fixed into the unitary whole plain bearing with the suspension bearing body, wherein:
Suspension bearing body two ends have annular groove, and corresponding annular groove place is provided with sealing member, and sealing member is provided with the boss of corresponding annular groove, and boss embeds in the annular groove and through pressure ring and is anchored on suspension bearing body two ends;
Described sealing member and axis body contact surface are provided with the sealing and dustproof circle.
Advantage of the utility model and beneficial effect:
The utility model can be realized the transmission of helix transporting device material effectively, and compact conformation effectively guarantees the material stream passed section.Adopt heatproof, withstanding corrosion, dust-proof sealing structure between bearing and the outside pressure ring, can reduce the loss to bearing effectively, sealing is strict, dependable performance.The utility model can effectively guarantee the circulation of material in the catalyst plant remote course of conveying of material little to powder and tempering property, the material latch up phenomenon can not take place, and is simple in structure, sealing is reliable, the service life of effectively improving bearing.
