Description

TECHNICAL FIELD

[0001] The utility model is suitable for material anti -blocking technical field, provide a kind of bin pulse discharging device. BACKGROUND

[0002] The ore produced by mine is often temporarily stored in storage bin before being sent to the next processing procedure. For example, the coal mined needs to be temporarily stored in kiloton material storage bin, and then the delivery quantity is controlled according to market demand, transportation conditions and other restrictions.

[0003] However, due to the influence of gravity, the lump coal is easy to be extruded into a group, which can cause arching and blocking of the coal in the storage bin, and further cause the problem of no discharging.

[0004] For the above problems, the Chinese patent with application number "202322295877.5" discloses "a bulk material storage silo dredging equipment", and its technical solution is: "the dredging structure is fixedly arranged inside the silo, and the condensed part of the stored material is removed and dispersed by elastic vibration; the dredging structure includes a belt, an oil cylinder, a fixer, a first steel wire rope and a second steel wire rope; the belt is arranged inside the silo; the oil cylinder is fixedly arranged at the bottom of the silo; the fixer is fixed above the silo; the two ends of the first steel wire rope are fixedly connected with the belt and the oil cylinder respectively; the two ends of the second steel wire rope are fixedly connected with the belt and the fixer respectively; the equipment can solve the problems of the current material silo dredging equipment, such as ineffective dredging, small action coverage area and dangerous dredging process".

[0005] However, the above-mentioned scheme has the disadvantage that the steel wire rope and belt structure recorded therein is extremely easy to break, and once the above-mentioned structure breaks, it is still difficult to play the role of dredging the material.

[0006] In order to solve the above problems, the prior art also uses an air cannon for coal mine dredging, such as the Chinese patent with application number "CN202322191536.3", which discloses "a boiler coal bunker structure with a clear block air cannon", the technical solution of which is: "including a coal bunker pipeline and an air cannon assembly, one side of the air cannon assembly is fixedly penetrated by an impact pipeline, the left and right ends of the outer surface of the impact pipeline are movably penetrated by two connecting ropes. The utility model is fixedly connected through the connecting rope, the linkage ring and the closure plate. When the air cannon assembly discharges the air shock wave through the impact pipeline, it can simultaneously drive the linkage ring to move downward. When the linkage ring moves downward, the closure plate is in an open state through the connecting rope. After the impact wave is released, the telescopic rod pushes the closure plate, so that the bottom of the closure plate is always in a state of adhesion with the bottom of the impact pipeline, so that the coal scattered by the impact wave cannot splash into the inside of the impact pipeline and cause blockage, thereby affecting the intensity of the next impact and the performance of the air cannon assembly next time. The time of later maintenance is reduced".

[0007] However, the air cannon in the above scheme is installed on the side wall of the coal bunker converging port, which needs to be additionally punched in the side wall of the coal bunker and erected during installation, and the installation process is too cumbersome.

[0008] Therefore, how to more simply dredge the blocked coal mine and improve the coal mine feeding speed is a difficult problem currently faced. Utility model content

[0034] In order to facilitate the fixation of pulse air pipe 2, a plurality of fixed holes 12 are formed on support table 11, pulse air pipe 2 is installed in fixed hole 12, and one end of pulse air pipe 2 extends towards the bottom of coal bunker 1.

[0035] Preferably, fixed hole 12 includes first through hole 121 and second through hole 122, one end of first through hole 121 and second through hole 122 towards the bottom of coal bunker 1 is connected, the inner diameter of first through hole 121 is smaller than the inner diameter of second through hole 122, and fixed disc 21 cooperating with second through hole 122 is installed on the side wall of pulse air pipe 2.Fixed disc 21 is installed in second through hole 122, which increases the contact area of pulse air pipe 2 and support table 11, further increases the stability of pulse air pipe 2, and reduces the probability of pulse air pipe 2 falling off.

[0036] In order to further fix the pulse air pipe 2, the second through hole 122 is provided with a third through hole 123 away from one end of the first through hole 121, the inner diameter of the third through hole 123 is larger than that of the second through hole 122, a positioning ring 23 is arranged in the third through hole 123, the positioning ring 23 is arranged around the pulse air pipe 2, a plurality of positioning holes 232 are arranged on the positioning ring 23, a threaded hole 22 matched with the positioning hole 232 is arranged on the fixing disc 21, and the positioning hole 232 is bolted with the threaded hole 22. The positioning ring 23 limits the fixing disc 21 in the second through hole 122, avoiding displacement problem.

[0037] In order to facilitate the fixation of the fixing disc 21 in the second through hole 122, an external thread can be arranged on the outer wall of the fixing disc 21, and an internal thread is arranged on the inner wall of the second through hole 122, and the two are threadedly connected.

[0038] The pulse air pipe 2 will vibrate violently when it sprays high-speed airflow, in order to avoid the influence of vibration on the stability of the pulse air pipe 2, the first elastic layer 231 is arranged at one end of the positioning ring 23 towards the fixing disc 21.

[0039] In order to further fix the pulse air pipe 2, a limiting ring 24 is installed in the second through hole 122, the limiting ring 24 is located between the fixing disc 21 and the first through hole 121, and the limiting ring 24 is arranged around the pulse air pipe 2, and the limiting ring 24 is provided with a limiting hole 241 matched with the threaded hole 22. The positioning ring 23, the fixing disc 21, the limiting ring 24 and the support table 11 are connected by bolts, which firmly fix the pulse air pipe 2 on the support table 11, and also can buffer the pulse air pipe 2 to a certain extent.

[0040] Preferably, the top and bottom of the limiting ring 24 are respectively provided with the second elastic layer 244 and the third elastic layer 243.

[0041] The length of the pulse air pipe 2 in the scheme is not strictly uniform, and pulse air pipes 2 with different lengths can be randomly buried, which can solve the problem of different heights of coal mine blockage.

[0043] When the coal bunker 1 stores the coal mine, the coal in the coal bunker 1 is difficult to rise smoothly due to the position of the feeding, which causes the coal mine to extrude one side of the pulse air pipe 2, which is easy to cause the pulse air pipe 2 to bend and even break. Therefore, the pulse air pipe 2 needs to be reinforced. Figures 7-8 As shown in the figure, the bottom of the support table 11 is provided with a support assembly 3, the support assembly 3 includes a support ring 31 connected with the support table 11, a support cylinder 33 and a plurality of support arms 32 are installed at the end of the support ring 31 away from the support table 11, the plurality of support arms 32 are arranged around the support cylinder 33, and the pulse air pipe 2 passes through the support ring 31 and the support cylinder 33 in sequence. The support arm 32 connects the support ring 31 and the support cylinder 33, when the pulse air pipe 2 is laterally extruded, the support cylinder 33, the support arm 32 and the support ring 31 will all share a part of the pressure, thereby increasing the pressure bearing capacity of the pulse air pipe 2 and reducing the probability of its breakage.
