Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The vibrating screen is a common screening device, and the main principle of the vibrating screen is to screen out materials with required particle sizes from a large number of materials with different particle sizes by utilizing the vibration and screen holes of the vibrating screen. For example, vibrating screens are widely used in the field of coal dust screening.

Coal is an important energy source and also an important raw material in metallurgy and chemical industry. The method is mainly used for combustion, coking, gasification, low-temperature dry distillation, hydrogenation liquefaction and the like. 1. The coal is used for combustion, is an important energy resource for human beings, and can be used as industrial and civil fuel. 2. And (2) coking, namely, putting coal into a dry distillation furnace, heating the coal in an isolated manner, gradually decomposing organic matters in the coal along with the rise of temperature, wherein volatile substances escape in a gaseous state or a steam state to form coke oven gas and coal tar, and the non-volatile solid residue is coke. Coke oven gas is a fuel and also an important chemical raw material.

The blast furnace smelting needs coke, and the coke has the function of providing heat required by the smelting process in the blast furnace; a reducing agent required for reducing iron ore; and a framework for maintaining the air permeability of the blast furnace material column (especially the reflow zone and the part below the reflow zone). The blast furnace injection coal powder is pulverized anthracite powder or bituminous coal powder or mixed coal powder of the two which is directly injected into the furnace from a blast furnace tuyere so as to replace coke and play a role in providing heat and reducing agent.

In blast furnace smelting, when a coal powder preparation system operates, raw coal is ground and dried to form coal powder, then the coal powder is settled in a cloth bag ash hopper of a powder collection system, falls down along a lower coal pipeline at the bottom of the lower ash hopper, enters a coal powder bin through a lower coal valve group and a vibrating screen, and is finally split-packaged into each injection tank from the coal powder bin. In the production process, the vibrating screen is a device with higher failure rate in a blast furnace coal powder preparation system, once the vibrating screen fails, a lower coal pipeline on the upper part of the vibrating screen is blocked by coal powder, so that the coal powder cannot be conveyed to a coal powder bin, and the smooth production is influenced.

In the shale shaker, the higher part of fault frequency generally is the motor, and high-efficient maintenance, the change of motor are very important to going on smoothly of blast furnace smelting production, and traditional motor is generally installed in the below of screen frame, and this mounted position is very inconvenient to the maintenance of motor, seriously influences the maintenance of motor and the ageing of changing, and then influences the smooth going on of blast furnace smelting.

To the above problem, the embodiment of the utility model provides a vibrating screen can make the maintenance of motor and screen frame, change more convenient.

In order to make the technical solutions and advantages of the present invention clearer, the following will describe the embodiments of the present invention in further detail with reference to the accompanying drawings.

On the basis of guaranteeing the maintenance space of the side circumference and the top of the vibrating screen, the maintenance space of the lower part of the vibrating screen is further increased through the hollow part 320, so that the vibrating screen is more convenient to maintain and replace.

An electric cabinet 800 for controlling the motor 200 and the screen body 100 is attached to a panel of a side of the frame 300.

Since the screen body 100 needs to be driven by the motor 200 to vibrate and thus to drive the screen mesh in the screen body 100 to vibrate for the purpose of performing vibratory screening on the material, the screen body 100 needs to be movably connected to the frame 300, and in this exemplary embodiment, the screen body 100 is movably connected to the top plate portion 310.

As shown in fig. 1 and 4, according to an exemplary embodiment of the present invention, the screen body 100 is movably connected with the frame 300 by the elastic member 122.

Optionally, elastic member 122 may be a coil spring, the bottom of screen frame 100 is connected with top plate 310 of frame 300 through a plurality of coil springs, when motor 200 drives screen frame 100 to vibrate, because screen frame 100 is connected at top plate 310 through coil spring, therefore screen frame 100 all has the degree of freedom in horizontal direction and vertical direction, make screen frame 100 can vibrate in a plurality of directions, the combined action of a plurality of directions vibration, make the screening effect of screen cloth better, in addition, because the vibration of screen frame 100 is diversified, can avoid the jam of screen hole to a certain extent.

For example, the lower portion of the screen body 100 is provided with a discharging chamber 121 formed of a funnel-shaped member, and the discharging hole 150 is provided at the bottom of the discharging chamber 121.

The material to be screened enters the screen cavity of the screen body 100 through the feed port 140, the required material is screened out through the screen by the vibration of the screen body 100, and the required material leaves the screen cavity from the discharge port 150 and enters the collection barrel 700 through the flexible pipe 600.

The pipe for transferring the material connected to the discharge hole 150 needs to accommodate the vibration of the screen body 100, and thus, the pipe is a flexible pipe 600, for example, the flexible pipe 600 may be a corrugated pipe. The flexible pipe 600 can better adapt to the vibration of the screen body 100, and when the screen body 100 vibrates, the flexible pipe 600 can swing along with the vibration, so that the problem that the vibration of the screen body 100 is influenced due to poor adaptability of a pipeline is avoided.

When the material is screened, large particles or materials with the size equivalent to that of the screen holes are often blocked in the screen holes, and the screening efficiency is seriously influenced.
