Description
Technical Field
The utility model relates to an ore pass, in particular to an ore pass device.
Background
The draw shaft is widely used in mining as one of ore transportation methods. The ore is fed by the dead weight of the ore, so that the method has the advantages of low energy consumption and low cost, and transportation equipment can be saved; meanwhile, a certain amount of ores are stored in the ore pass, so that the balanced production of mines is facilitated. The bottom structure of present ore drop shaft is that heavy slat feeder directly sets up the opening part in ore storage storehouse below one side, therefore the thickness of frontal wall (storing the wall between ore storage storehouse and the breaker chamber promptly) generally only has 1 ~ 2m, nevertheless can lead to the wearing and tearing attenuation of the frontal wall in ore storage storehouse in the operation throughout the year of drop shaft to lead to the frontal wall to lose original intensity, produce the fracture, the potential safety hazard appears. Particularly, when the chute is blocked, a large amount of ores fall to the bottom of the chute from a high position of the chute instantly, and the generated shock waves easily cause damage to the frontal wall and safety accidents. Meanwhile, a large amount of ores in the ore storage bin are directly pressed on the heavy plate feeder by dead weight, so that the load of the heavy plate feeder is increased.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: in view of the above disadvantages, the present invention provides an ore pass device with increased safety.
The technical scheme is as follows: in order to solve the problems, the utility model adopts an ore chute device which comprises a main chute, a chute opening, a forehead wall and a crusher chamber and is characterized by further comprising a buffer ore bin, wherein the buffer ore bin is positioned below the main chute, the buffer ore bin is communicated with the main chute through the chute opening, the chute opening is obliquely arranged, a buffer ore bin is arranged in the horizontal extending direction of an outlet of the chute opening, an outlet of the buffer ore bin is arranged under the buffer ore bin, the crusher chamber is arranged on one side of the buffer ore bin, an inlet of the crusher chamber is communicated with an outlet of the buffer ore bin, the crusher chamber and the chute opening are respectively positioned on two sides of the buffer ore bin, the forehead wall is positioned between the crusher chamber and the main chute, the forehead wall is positioned above the buffer ore bin, and the thickness of the forehead wall is larger than the length of the top wall of the buffer ore bin.
Furthermore, the cross sectional area of the buffering ore bin is gradually reduced along the vertical direction.
Furthermore, steel plates are buried at two sides of the outlet of the buffer ore bin.
Further, ore storage bin is arranged below the main ore pass, the chute is arranged at the bottom of the ore storage bin, the ore storage bin is vertically arranged, and the vertical extending direction of the ore storage bin is parallel to the extending direction of the main ore pass.
And one end of the plate feeder is positioned below the outlet of the buffer ore bin, and the other end of the plate feeder is positioned in the crusher chamber.
Further, slat feeder level or slope setting, slat feeder extending direction and the contained angle of horizontal direction are 0 ~ 20 degrees, and when the slope set up, the vertical one end highly is less than the one end that slat feeder is located the breaker chamber of slat feeder in the buffering ore bin.
Furthermore, the included angle between the extending direction of the chute opening and the horizontal direction is 60 degrees.
Further, the ore storage bin, the chute opening and the buffering ore bin are formed by pouring reinforced concrete.
Has the advantages that: compared with the prior art, the utility model has the advantages that the thickness of the frontal wall can be effectively increased (generally to 7-8 m) by adding the buffer ore bin, the safety performance of the frontal wall is improved, and the potential safety hazard is reduced. Meanwhile, the buffer ore bin is additionally arranged, so that a large amount of ores in the main chute and the ore storage bin are prevented from being directly and heavily pressed on the heavy plate feeder, and the load of the heavy plate feeder is reduced.

Detailed Description
As shown in fig. 1 and 2, an ore chute device in this embodiment includes main chute 1, bellmouth 2, ore storage bin 3, chute 4, buffer ore bin 5, slat feeder 6, forehead wall 7 and breaker chamber 8, main chute 1 and ore storage bin 3 are hollow cylinders, and bellmouth 2, ore storage bin 3, chute 4, buffer ore bin 5 are formed by pouring reinforced concrete, main chute 1 extending direction is parallel to vertical direction, the export of main chute 1 is connected with the entry of bellmouth 2, bellmouth 2 is located main chute 1 below, the cross-sectional area of bellmouth 2 is crescent when entering by the mouth, then does not change, reduces gradually again, the cross-sectional area of bellmouth 2 exit is greater than the entrance cross-sectional area.
The export of horn mouth 2 and the entry linkage of ore storage storehouse 3, ore storage storehouse 3 is located horn mouth 2 below, and 3 extending direction in ore storage storehouse is on a parallel with vertical direction, and 3 bottoms in ore storage storehouse set up the slope, are favorable to the whereabouts of ore, and the export of ore storage storehouse 3 sets up in the bottom side, and with the entry linkage of swift current mouth 4, the setting of the slope of swift current mouth 4, in this embodiment, 4 extending direction in swift current mouth and horizontal direction contained angle are 60 degrees.
The outlet of the chute 4 is horizontally extended and provided with a buffering ore bin 5, the outlet of the chute 4 is connected with the inlet of the buffering ore bin 5, the buffering ore bin 5 is positioned below the ore storage bin 3, the outlet of the buffering ore bin 5 is arranged under the buffering ore bin 5, the cross sectional area of the buffering ore bin 5 in the direction from the inlet to the outlet is gradually reduced, the side wall of the buffering ore bin 5 can bear the weight of partial ore, the phenomenon that a large amount of ore of the ore storage bin is directly and heavily pressed on the heavy plate feeder is avoided, the load of the heavy plate feeder is reduced, and the potential safety hazard is reduced; and the steel plates are buried at the two sides of the outlet of the buffering ore bin 5, so that the abrasion of the ore to the two sides of the outlet can be reduced.
