The specific meaning of the terms described above will be understood by those of ordinary skill in the art as the case may be.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, but the present utility model may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the utility model.
Specific embodiments of the present utility model are described in detail below.
The utility model provides a concrete embodiment of a chute buffer device, which comprises a chute main body, wherein the chute main body comprises a feeding vertical section 11 and a discharging inclined section 12, the discharging end of the feeding vertical section 11 is in butt joint with the feeding end of the discharging inclined section 12, one side of the inner wall of the feeding vertical section 11 at the impact position of a logistics is respectively provided with a first buffer backing plate 111 and a second buffer backing plate 112 along the vertical direction, the bottom plate of the discharging inclined section 12 at the rolling position of the materials is provided with three protection backing plates 121 along the inclined direction, the outlet end of the discharging inclined section 12 is surrounded with an outlet baffle 122, the coverage area of the outlet baffle 122 is positioned in a belt of a lower belt conveyor 2, and a gap is reserved between the outlet baffle 122 and the belt of the lower belt conveyor 2; a travel switch 124 is arranged on the inner wall of the discharging inclined section 12 opposite to the bottom plate of the discharging inclined section 12, a vibrator 123 is arranged on the outer wall of the discharging inclined section 12, and the travel switch 124 is electrically connected with the vibrator 123 and the motor of the upper belt conveyor 3.
When the coke feeding device is particularly used, the roller of the upper layer belt conveyor 3 runs, the belt conveys coke forwards, the coke is impacted onto the first buffer backing plate 111 or the second buffer backing plate 112 of the opposite feeding vertical section 11 in a parabolic manner from the discharge end of the upper layer belt conveyor 3, and the buffer backing plate in the embodiment reduces the impact of materials on the side wall of the feeding vertical section 11; the materials falling onto the first buffer backing plate 111 or the second buffer backing plate 112 slide onto the protection backing plates 121 of the discharging inclined section 12, coke is filled between all the protection backing plates 121, the protection backing plates 121 filled with coke form a protection buffer layer of the discharging inclined section 12, the subsequent coke slides on the protection buffer layer, the coke cannot directly contact with the chute bottom plate, abrasion of the coke and the chute bottom plate is reduced, and the outlet baffle 122 limits the coke at the discharging end of the discharging inclined section 12 to slide onto a belt of the lower belt conveyor 2. The outlet baffle 122 in this embodiment plays a limiting role, and prevents the coke at the discharge end of the discharge inclined section 12 from falling to the outer side of the belt of the lower belt conveyor 2. And the outlet baffle 122 in the embodiment is made of rubber materials, so that the effect of limiting can be achieved, meanwhile, the coke conveying effect of the lower belt conveyor 2 is not influenced, and the smoothness of conveying materials by the lower belt conveyor 2 is ensured. The oblique orientation of the discharge chute 12 in this embodiment facilitates buffering of the material.
When a large amount of coking coal is poured into the feeding vertical section 11, the conveying speed of the lower belt conveyor 2 may not meet the requirement of coking coal pouring, a blocking phenomenon may occur in the discharging inclined section 12, after the blocking of the discharging inclined section 12 is accumulated to a certain extent, the coking coal which is conveyed subsequently impacts and touches the travel switch 124, the normally closed contact of the travel switch 124 is opened, the normally open contact of the travel switch 124 is closed, the normally closed contact of the travel switch 124 in the embodiment is connected in series in a motor power supply circuit of the roller of the upper belt conveyor 3, and the normally open contact of the travel switch 124 in the embodiment is connected in series in a power supply circuit of the vibrator 123; when the normally closed contact of the travel switch 124 is opened, the normally open contact of the travel switch 124 is closed, the upper belt conveyor 3 stops running, the vibrator 3 is started to vibrate materials in the chute, dredges in time, and prevents the materials from continuously accumulating. When the materials in the chute are completely dredged, the travel switch 124 returns to the original position, the normally-closed contact of the travel switch 124 is closed, the normally-open contact of the travel switch 124 is opened, the upper belt conveyor 3 continues to run, and the vibrator 3 is closed.
In this embodiment, the plate body directions of the first cushion plate 111 and the second cushion plate 112 are located in the vertical direction. The direction of the plate body of the buffer backing plate is positioned in the vertical direction, so that coke can be prevented from directly striking the feeding vertical section 11 to a large extent.
In one embodiment of the present utility model, the plate body direction of the protection pad 121 is perpendicular to the bottom plate of the discharging inclined section 12. The direction of the plate body of the protective backing plate 121 can thicken the protective buffer layer to a large extent, so that abrasion of coke to the chute bottom plate is reduced.
In particular, in one embodiment, the second cushioning pad 112 located below is closer to the middle of the feed vertical section 11 than the first cushioning pad 111 located above. After the coke at the discharge end of the upper belt conveyor 3 is parabolic and impacted to the first buffer backing plate 111 of the opposite feeding vertical section 11, the coke can pass through the buffer of the second buffer backing plate 112 again, so that the impact force of the coke on the bottom plate of the discharging inclined section 12 is reduced, and the chute transportation realizes segmented layered discharge, so that the normal production of a coke conveying system is ensured.
Preferably, the first cushion pad 111, the second cushion pad 112 and the protection pad 121 are all made of i-steel. The buffer backing plate and the protection backing plate made of I-steel have higher strength and better wear resistance.
