Abstract
The invention discloses an anti-feedback device of a central chain elevator. The anti-feedback device comprises a sleeve (1), a connection rack (6) and an external roller (8); and the sleeve (1) is sleeved outside a driving shaft of a head pulley assembly of the central chain elevator, and the connection rack (6) is arranged on the sleeve (1), and is connected with the external roller (8). The sleeve (1) is composed of two semi-circular sleeves (2) which are fixed through a butt-joint bolt (5). The anti-feedback device is novel in structure, practical, reliable, convenient to use, firm and durable, and suitable for conveying powder materials in large tonnage and large height, and can be used for effectively preventing the materials from falling in the bottom of the shell to cause the feed back while discharging the materials, and preventing the materials from infiltrating into a transmission component, therefore, the service life of the transmission component can be prolonged, the normal production of an enterprise can be guaranteed, the energy and resource are saved, and the economic benefit is obvious.
Description
Technical field
The present invention relates to a kind of block construction of conveying machinery, especially a kind of central chain gig is prevented feeding back device.
Background technology
Central authorities' chain bucket elevator adopts with transmission gear and drives plate chain, hopper at binary channel, the enclosed construction load transfer device in the circulating motion mode.The hopper that is fixed in the plate chain back side is equipped with material, and material is generally powder, piece material or mixture, and hopper runs to overturn behind the top of transmission gear material is drawn off.Because the characteristic difference of material, as powdery, small particles material, can't all fall into the designated area during discharging, having partial material is inhaled under the air-flow effect in zero load (backhaul) passage, and the hopper back, fall into gig afterbody (bottom) at last, increase the power that takes of motor on the one hand, repeat acting, the waste resource.On the other hand, feed back can produce acceleration/accel by by gravity, housing is worn and torn, can be worn out in a week, the dust contaminated environment that leaks causes housing wearing and tearing, worn out, weakens compressive strength, need to carry out repair welding increases labor strength for this reason, and outdoor work lacks the insecurity that protection increases the workman.Infiltrate the drive disk assembly inner structure, strengthen the plate abrasion of chain.For a long time operation will make and drive disk assembly reduction of service life reduce its value of service.Hopper shell is easy to worn out loss or produces gross distortion, influences ordinary production.
Moreover, change chain and can cause enterprise to stop production on the one hand, bring economic loss to enterprise.The opposing party's panel chain cost is higher, increases the operation expense of equipment, the resource of waste enterprise.
Therefore, need a kind of device that can prevent feed back badly, overcome above-mentioned drawback.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective; provide a kind of later-model central chain gig to prevent feeding back device; can accomplish the discharging smoothness for carrying the superfine powder material; anti-feed back; the drive disk assembly of preventive device is injury-free effectively, reduces the wasting of resources, guarantees that equipment normally moves; ensure enterprise's ordinary production effectively, for the user economizes on resources.
Technical scheme of the present invention is:
A kind of central chain gig is prevented feeding back device, comprises sleeve pipe, hitch and outer cylinder, and described sleeve pipe is nested with the imput shaft outside at central chain gig great wheel assembly, and sleeve pipe is provided with hitch, and hitch is connected with outer cylinder.
Described sleeve pipe is made up of two semicircle sleeve pipes, and two semicircle sleeve pipes are by the butt joint bolt.
Three hitch of described outside of sleeve welding, each hitch is provided with the hitch stay bearing plate, and the hitch stay bearing plate is connected with outer cylinder.
Described outer cylinder is made up of three outer cylinder tiles, and three outer cylinder tiles and hitch stay bearing plate pass through bolted connection.
Described outer cylinder edge is provided with the dust-break side plate.
Be provided with inner shield ring in the described sleeve pipe.
The anti-feeding back device of central chain gig of the present invention comprises: sleeve pipe, hitch, outer cylinder.Sleeve pipe is hemisected, wrap in the outside of the imput shaft of great wheel assembly, with the butt joint Bolt Connection.Sleeve outer wall is divided into trisection, welds three supports, again three supports are connected firmly with outer cylinder.
The beneficial effect of practicality of the present invention is:
Structure of the present invention is novel, and is practical reliable, easy to use, sturdy and durable, is fit to the conveying of the granular material of the big height of large-tonnage, and material falls into housing bottom and causes feed back when effectively preventing the material discharging, and reduces the inside that material infiltrates drive disk assembly.Thereby can prolong service life of biography portion parts, and guarantee enterprise's ordinary production, be enterprise's energy savings and resource, remarkable in economical benefits.
The anti-feeding back device of central chain gig of the present invention is by the mating reaction of sleeve pipe, hitch and outer cylinder, produce eddy flow systemicly, utilize the motion of aerodynamic force control powder, powder is concentrated to blow targetedly, avoided the random series of malpractice of bringing of flying upward of powder everywhere.Simultaneously, avoid the wearing and tearing of hopper shell, improved the service life of gig.
Description of drawings
Fig. 1 is an inner structure scheme drawing of the present invention.
Fig. 2 is an external structure scheme drawing of the present invention.
Among the figure: 1 be sleeve pipe, 2 for the semicircle sleeve pipe, 3 for outer cylinder tile, 4 for inner shield ring, 5 for to connecting bolt, 6 for hitch, 7 for the hitch stay bearing plate, 8 for outer cylinder, 9 for the dust-break side plate.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described:
As Fig. 1, Fig. 2, a kind of central chain gig is prevented feeding back device, comprises sleeve pipe 1, hitch 6 and outer cylinder 8, and described sleeve pipe 1 is nested with the imput shaft outside at central chain gig great wheel assembly, and sleeve pipe 1 is provided with hitch 6, and hitch 6 is connected with outer cylinder 8.
Sleeve pipe 1 is made up of two semicircle sleeve pipes 2, and two semicircle sleeve pipes 2 are by fixing to connecting bolt 5.The sleeve pipe 1 of two semicircle sleeve pipe 2 compositions wraps in the imput shaft outside of central chain gig great wheel assembly.
Three hitch 6 of sleeve pipe 1 outside welding, each hitch 6 is provided with hitch stay bearing plate 7, and hitch stay bearing plate 7 is connected with outer cylinder 8.
Be provided with inner shield ring 4 in the sleeve pipe 1.Be convenient to be connected cooperation with the imput shaft of central chain gig great wheel assembly.
Embodiment recited above is described preferred implementation of the present invention; be not that design of the present invention and scope are limited; do not breaking away under the design concept prerequisite of the present invention; common engineering staff make technical scheme of the present invention in this area various modification and improvement; all should fall into protection scope of the present invention, the technology contents that the present invention asks for protection all is documented in claims.
