Description

Ore chute of horizontal unloading system

Technical Field

The invention relates to a chute of a horizontal unloading system.

Background

The ore chute is an indispensable facility in the mine production process, and is an intermediate facility for ores to enter an ore storage bin in the production process so as to meet the requirement of continuous operation of subsequent process equipment; the conventional ore working platform pushes out a skip bucket from a lifted ore through a hydraulic station for ore unloading, and the ore enters a lower conveying belt through an ore chute for continuous transportation; for the ore chutes, the service life is required to be long, the maintenance amount is small, and the structure is simple and durable as much as possible; the influence of the hardness of the ore, the size of an ore block, the ore unloading height of the ore and other factors on the bottom plate of the ore chute and the impact and abrasion of the bottom plate is very serious, so that the concrete poured at the bottom of the ore chute is perforated to break a hole, the structure of the ore chute is damaged, the ore flows into a shaft to damage a shaft facility, the production cannot be continued, and the production process is greatly influenced.

At present, two ways of improvement are adopted in mines, one way is to additionally arrange a wear-resistant lining plate on a bottom plate at a rock falling position of an ore chute, but the impact force is large in the production process, maintenance or replacement is needed for a period of time, and excessive wear and perforation or falling caused by ore impact force are avoided, so that the due effect cannot be achieved; the other one is through closing ore drawing machine of chute below for the ore piles up upper portion, keeps high material level operation always, this can reach the purpose of buffering, but because the ironware of source can't all be examined out, the ironware probably punctures the conveyer belt when falling the conveyer belt, and then tears the conveyer belt, must close the ore drawing machine and maintain, because the ore is close full storehouse in the chute this moment, so the ore that must stop of front end promotes and stops to unload the ore, wait to maintain the back and just can continue to go on, influence production speed.

Detailed Description

In order to make the purpose and technical solution of the present invention clearer, the present invention is further described with reference to the accompanying drawings and embodiments:

the chute of the horizontal unloading system shown in fig. 1 comprises a chute body 1, wherein a feeding port 2 for feeding materials is arranged at the upper end of the chute body, and an ore drawing machine (not shown in the figure) is connected to the tail end of the chute body; the bottom plate 3 of the tank body is a wear-resistant lining plate; a material blocking body 4 is arranged on the groove body at the feeding port; the material blocking body 4 is used for stacking materials with a certain height at the feeding port to form a protective layer, and after the materials are fully stacked, the materials overflow from the upper part of the material blocking body 3 and fall into the middle section of the groove body 1.

Preferably, the blocking bodies 4 are poured into the side walls on two sides of the groove body by using concrete and are connected with the side walls of the groove body into a whole, so that the overall impact strength of the blocking bodies 4 is improved.

Preferably, the material blocking body 4 is formed by welding and overlapping a plurality of section steels or I-shaped steels;

preferably, as shown in fig. 2, a plurality of reinforcing ribs 5 are arranged on the side surface of the material blocking body 4; the reinforcing ribs connect a plurality of section steels or I-shaped steels into a whole, so that the overall impact strength of the material blocking body 4 is further improved.

Preferably, keep off the material body 4 top and be equipped with guard plate 6, avoid the material to keep off the wearing and tearing of material body 4 top, after using for a long time, only need change guard plate 6 can.

Preferably, the protection plate 6 is made of wear-resistant steel and is welded above the material blocking body.

Preferably, guard plate 6 is the rail, through the bolt fastening in keep off material body top, and ore enterprise has a lot of abandonment rails, to its make full use of, saves the cost, and the rail only needs to keep off material body upper end opening from taking the bolt hole, can be fixed in the rail through the screw bolt and keep off material body top, and change more easily for the welding after the damage.

Preferably, as shown in fig. 3, a protection plate 6 is arranged above the material blocking body; a plurality of baffles 7 are arranged above the protection plate, and a flash port 8 is formed between two adjacent baffles; so that the ores can be uniformly dispersed and transferred in the transferring process to play a role in protecting the tank body.

Preferably, the protection plate 6 is made of wear-resistant steel and is welded above the material blocking body 4; the baffles 7 are made of wear-resistant steel and are welded above the protection plate 6.

The principle of the invention is as follows:

the ore promotes to unloading platform 9 from pit shaft 8, release skip 91 through hydraulic pressure station (not shown in the figure) and unload the ore, the ore gets into the cell body from dog-house 2, it makes the ore pile up until reaching fender material body 4 height to keep off material body 4, form the protective layer, afterwards, the ore that skip 91 lifted off all strikes the protective layer formation, can not destroy the production of the bottom plate of cell body, avoided the ore consequently and flowed into the pit shaft and damaged the pit shaft facility, make production unable continuation go on, cause the problem of very big influence to the production flow.

Meanwhile, as the protective layer is formed above, the ore chute can operate at a low material level, when an iron part pierces the conveyer belt and needs to be maintained, the ore drawing machine is only needed to be closed, and the front end can continue to work (the maintenance time is generally 10-15 minutes, the ore chute keeps the low material level operation to enable the chute body 1 to have enough containing space to contain ores thrown in during the maintenance), so that the business volume of 944 ten thousand yuan-1228 yuan of a company can be increased every month, and the effect is very good.
