Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a tail shell of a bucket elevator specially used for light and complex materials. Background Art

[0002] At present, there are three main ways to dispose of urban waste: sanitary landfill, incineration and composting. Among them, incineration has gradually become the mainstream way of harmless waste treatment. Waste incineration technology is in its infancy in my country. Industrial kilns are used to co-dispose of RDF materials. RDF materials are light and complex materials. From the perspective of processing volume and application prospects, waste incineration power generation and cement kilns are currently the two largest and most concentrated areas for co-disposal of RDF materials. In these two fields, the transportation of light and complex materials is mainly carried out by conveying equipment such as grab buckets, large-angle belt conveyors, and tubular belt conveyors. However, belt conveyors have the disadvantages of large space occupation and inflexible process layout, and grab buckets have the disadvantages of low conveying efficiency and intermittent operation. Considering the factors of land occupation, civil engineering, safety, efficiency, continuity, energy saving, and economy, the wire belt bucket elevator is one of the more ideal conveying equipment.

[0003] However, the materials that traditional bucket elevators can transport are mostly dry powder granular materials or small granular materials, and the bulk density of the materials is generally above 0.5t / m3. Due to the complex material properties, harsh working environment, and difficulty in feeding and unloading of light and complex materials, ordinary bucket elevators are difficult to meet the above transportation requirements.

At least one group of flow-aiding nozzle assemblies is arranged on the outer wall of the bottom plate 8 of the feed port shell, and each group of flow-aiding nozzle assemblies includes a nozzle mounting base 4 and at least one nozzle 5. The nozzle mounting base 4 is fixed on the outer wall of the bottom plate 8 of the feed port shell, and the nozzle mounting base 4 is a hollow part with a cavity arranged therein. The bottom plate 8 of the feed port shell has an air port at a position corresponding to the nozzle mounting base 4, and the wear-resistant plate 3 has an avoidance port 6 at a position corresponding to the air port. The nozzle mounting base 4 has a mesh plate 7 at a position corresponding to the air port, and the mesh plate 7 and the nozzle mounting base 4, and the mesh plate 7 and the feed port shell 2 can be fixed together by welding. The nozzle 5 is installed on the side of the nozzle mounting base 4 away from the bottom plate 8 of the feed port shell, and a threaded mounting hole can be opened on the nozzle mounting base 4. The threaded mounting head of the nozzle 5 is installed on the nozzle mounting base 4 by threaded connection with the threaded mounting hole, and the nozzle 5 is connected to an external air source through an air pipe.

[0025] In this embodiment, three groups of flow-aiding nozzle assemblies are arranged on the outer wall of the bottom plate 8 of the feed inlet housing, and each group of flow-aiding nozzle assemblies includes a nozzle mounting base 4 and three nozzles 5 mounted on the nozzle mounting base 4. The bottom plate 8 of the feed inlet housing is an inclined bottom plate, and the three groups of flow-aiding nozzle assemblies are arranged in sequence along the inclined surface of the inclined bottom plate, and the three nozzles 5 of each group of flow-aiding nozzle assemblies are arranged in sequence in the front-rear direction of the nozzle mounting base 4.

[0026] The left and right sides of the feed port housing 2 are respectively provided with feed port inspection doors 9 that can be opened or closed. The feed port inspection door 9 can adopt a hinged door of a common structure. During the feeding process, due to the high adhesion of light and complex materials, feeding difficulties may occur. The feed port inspection door 9 can be easily opened to clear the materials.

[0027] Slag cleaning doors 10 that can be opened or closed are respectively provided near the bottom on the front and rear sides of the tail casing 1, so that the slag cleaning doors 10 can be opened conveniently to clean out the accumulated materials at the bottom of the tail casing 1 in time. The slag cleaning door 10 includes a slag cleaning door body 11, which is provided with a circle of sealing strip on the side facing the tail shell body 1, and the slag cleaning door body 11 and the tail shell body 1 are pressed and locked by two sets of upper and lower eccentric pressure rod assemblies 12. Each set of eccentric pressure rod assemblies 12 includes a pressure rod 13 and two sleeve rings 14. The tail shell body 1 is provided with a slag cleaning opening at a position corresponding to the slag cleaning door body 11. The two sleeve rings 14 are respectively fixed on the left and right sides of the slag cleaning opening of the tail shell body 1, and the left and right ends of the pressure rod 13 pass through the sleeve holes of the left and right sleeve rings 14 respectively. At least one eccentric convex ring 15 is provided in the middle section of the pressure rod 13. A pad 16 is provided on the outer side of the slag cleaning door body 11 at a position corresponding to the pressure rod 13. By rotating the pressure rod 13, the convex portion 17 of the eccentric convex ring 15 on the pressure rod 13 is pressed against the pad 16 on the outer side of the slag cleaning door body 11, so as to realize the pressing and locking of the slag cleaning door body 11 and the tail shell body 1. A pressure rod handle 18 is provided in the middle of the pressure rod 13 to facilitate the rotation of the pressure rod 13. Two door handles 19 are provided on the outside of the slag cleaning door body 11 to facilitate the installation and removal of the slag cleaning door body 11. In this embodiment, three eccentric convex rings 15 are provided in the middle of the pressure rod 13 to achieve multi-point compression of a single pressure rod 13 and the slag cleaning door body 11, thereby ensuring the compression effect of the slag cleaning door body 11.

[0028] When it is necessary to open the slag cleaning door 10, the pressure rod handle 18 is held and the pressure rod 13 is moved, so that the two ends of the pressure rod 13 rotate in the sleeve holes of the two rings 14, and the raised portion 17 of the eccentric convex ring 15 on the pressure rod 13 gradually moves away from the pad 16 on the outer side of the slag cleaning door body 11. When the raised portion 17 of the eccentric convex ring 15 on the pressure rod 13 is completely separated from the pad 16, there is a gap between the eccentric convex ring 15 on the pressure rod 13 and the pad 16.
