Technical Field
The invention relates to the technical field of mineral separation, in particular to a buffer device and a structure for roughly crushing large ores.
Background
In the process of ore dressing and feeding, the lump size of the fed ore is generally required to be 800mm x 800mm or 1000mm x 1000mm, but due to the fact that the blasting control difference and the product process required granularity are large or large ore is mixed in during shovel loading, the lump size of the ore often exceeds the standard, the processing capacity of a crusher is exceeded, and equipment is damaged. The proportion of large ore blocks is reduced in various mines by adopting various methods, such as secondary crushing by using an oil hammer, arrangement of a grid screen in a raw ore bin and the like. And a method for protecting equipment, enhancing equipment structure and arranging a steel chain curtain is adopted in part of mines.
But has the problems that:
1. the method of adopting a grizzly screen and an oil hammer to crush the large ores is reduced, so that the conventional production efficiency is seriously reduced, and the investment is large;
2. the equipment structure is enhanced from the equipment protection angle, and needs to be transformed according to the property test of each mine, so that the universality is poor, and the investment is large. The method for setting the steel chain curtain is universal, and has a good buffering effect on feeding of general lump ores, but has a poor buffering effect on large ores. In addition, the chain is easy to damage a single chain, so that the chain falls into the crusher, and accident potential is caused.

Drawings
FIG. 1 is a schematic view of the structure of the present invention.
In the figure: 1. a feeder; 2. a connection shield; 3. a crusher; 4. a cross bar; 5. shackle dismounting; 6. a buffer plate.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1: the most basic unit for realizing the functions of the invention
A buffer device for roughly crushing large ores comprises a cross rod 4, and a buffer plate 6 is hung on the cross rod 4. The cross bar 4 is usually a seamless steel tube.
Example 2: to facilitate replacement of the buffer plate 6
On the basis of embodiment 1, the cross bar 4 suspends the cushion plate 6 by means of the shackle 5.
Example 3: detailed description of example 1 or example 2
A coarse crushing large ore buffer structure comprises a feeder 1, an outlet of the feeder 1 is connected with an inlet of a crusher 3, and a coarse crushing large ore buffer device of claim 1 or 2 is arranged between the outlet of the feeder 1 and the inlet of the crusher 3.
The buffer plate 6 is fixed above the outlet of the feeder 1 in a suspension mode, the distance from the buffer plate to the lower inner wall of the machine head of the feeder 1 is determined according to the requirement of each mine on the feeding lumpiness, and the distance of 500mm can be selected by taking the ore requirement lumpiness of 800mm x 800mm as an example. When feeding ore lump degree is less than this section distance, the ore directly falls, when feeding ore lump degree is greater than this section distance, buffer board 6 is pushed away to the bold ore, extrudees, collides between buffer board 6 and unloading chute, 3 feed inlets of breaker, and the falling of resistance to play ore buffering effect.
Example 4:
a connecting shield 2 is arranged between the outlet of the feeder 1 and the inlet of the crusher 3, a coarse crushing large ore buffer device is arranged on the connecting shield 2, and a cross rod 4 is erected on the inner wall of the connecting shield 2.
Set up buffer board and linkage on connecting shield 2, trompil on connecting shield 2 both sides, the trompil position bears the position according to the buffer board plan and sets up directly over, guarantees more than 300mm according to connecting shield 2, prevents that connecting shield 2 from bearing inadequately.
And (3) inserting a seamless steel pipe into the hole opening position, wherein the size of the seamless steel pipe is determined according to the weight of the buffer plate and the loading condition, and the seamless steel pipe with the diameter of 120mm can be selected.
Three shackles 5 are cooperated to form a suspension mechanism, the first shackles 5 need to penetrate in advance when seamless steel pipes enter a connecting shield, and the shackles are selected according to the diameter and the bearing condition of the seamless steel pipes and can be selected to be 25T shackles.
The buffer plate 6 is a whole steel plate, the thickness of the steel plate can be 40mm-50mm, and the top of the buffer plate is provided with a hole to be connected with the shackle 5. The height of the buffer plate 6 is calculated and determined according to the distance from the required buffer plate 6 to the inlet chute plate of the crusher 3, and the distance of 500mm can be selected. The width of the buffer plate 6 is calculated and determined according to the diameter of the inlet of the crusher 3, the impact area of the large ore is mainly in the middle, the two sides of the crusher 3 are provided with guard plates, comprehensive consideration is given to the guard plates, and the distance between the two ends of the buffer plate 6 and the two sides of the inlet of the crusher 3 can be 500mm
Under normal conditions, the ore material is carried to the batcher aircraft nose through the batcher and gets into breaker 3 through connecting 2 chutes in the shield bottom.
Allowing the lumpy ore to directly enter the crusher 3 from a chute plate at the feed inlet of the crusher 3; when the lump degree of the ore exceeds the standard, the large ore extrudes the buffer plate 6 to enter the crusher.
By adopting the large ore buffer device, the crusher rotor and related accessories can be effectively protected, and the service life of the crusher is greatly prolonged. The service life of the crusher, particularly the rotor and related accessories is prolonged, and the hidden trouble is effectively reduced.
