Description

Screen eye cleaning apparature for sorting become a taoist}

The present invention relates to a screen eye cleaning device for screening particle size, and more particularly, by screening the screen mat by a rolling roll with a rubber ball to prevent clogging of the mat to increase screen efficiency and reduce manpower consumption. It relates to a screen snow cleaning device.

In general, sintered coke (COKES) screens are spun during the digestion of imported anthracite coals and bituminous coals. It is a facility that shreds the size, so that the rubber mat hole in the bottom of the coke screen is completely blocked due to the addition of moisture to prevent dust scattering during the shredding, and it does not sift the coal that enters the screen, and only serves to transport it to the rod mill.

The screening defect of the screen is caused by the suction power of the main blower (BLOWER), which is mixed into the raw material limestone, coke and anthracite coal in the sintering operation, passes through a charging igniter on the sinterer bogie, and ignites downward to be sucked downward. As sintering progresses, coke or anthracite is not maintained at the proper particle size of coke or anthracite, and crushed coke or anthracite is concentrated only in the upper part of the sintering machine trolley and inhibits the sintering process. Blocks the inflow of, and in the lower part of the bogie to produce a poor sintered ore due to the lack of fuel, which causes a huge obstacle to the operation of the blast furnace, resulting in a decrease in productivity and a decrease in the quality of the molten iron.

In addition, as shown in Figure 6 to stop the blockage 50 of the coke screen rubber mat hole, using a non-proprietary hand tool wire brush 51 or awl 52 is stopped and clogged with manpower at the top of the screen However, this not only consumes a lot of manpower and time, but also poses a very high risk of industrial safety accidents, causing secondary problems due to BIN inventory down during long hours of operation, and clogging again upon startup.

Therefore, the present invention was devised to solve the conventional problems as described above, by using a wire brush or auger at the top of the screen when the sintering coke screen rubber mat life-blocking phenomenon occurs by removing the blockage by manpower and industrial safety Problems such as the operation rate of the sintering equipment, the productivity of the accident occurs, the purpose is to improve the stability and productivity of the sintering operation by removing the blockage of the screen rubber mat hole automatically and automatically during the start-up of the equipment before the screen clogging occurs.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

A preferred embodiment of the screen eye cleaning device according to the present invention,

A plurality of rubber balls 32 are attached to the rotary roll 30, and the rubber balls 32 are connected by a rubber string 33 so that the rotary roll 30 reciprocates along the rail on the coke and the lower side. It is preferable that the rubber ball 32 taps the screen mat by the rotation of the roll 30.

As described with reference to this as follows.

When the screen rubber mat is clogged, a plurality of rubber balls 32 and a resilient rubber strap 33 are attached to the roll ROLL 30 and a driving device and a rotating roll for rotating the screen. A sensing sensor is provided at the lower end of the traveling device traveling rail for reciprocating compression and exit.

The rotary roll 30 is attached to the rubber ball 32 made of a plurality of rubber balls 32 and a good elastic rubber strap 33 to the body, and drilled a hole in the rotary roll 30 and thereon a female screw ( 42), align the center hole (HOLE) of the rubber strap 33 with the rubber balls 32 attached to both sides over the female screw 42, and attach the support plate 40 to the male screw (41). ) Is produced by tightening.

In addition, the rotary roll 30 is the screen mat (1) by the starter motor 35, the reduction gear 36, the drive sprocket kit (SPOR KET) 37, the drive chain 38, the driven sprocket kit 39 The rubber ball 32 beats the screen mat while rotating the phase to prevent screen clogging.

The up and down running of the screen of the rotary roll 30 is composed of a drive shaft 7 and a rope adjustment wheel (WHEEL) 6a, 6b of the reducer 8 and a shaft support bearing 10 connected to the shaft at an upper portion thereof. The device is installed at the screen inlet and is started like a screen so that the rotary roll 30 moves up and down along the travel rails 3a and 3b, and is sensed by the screen end sensor 4a and the entrance sensor 4b. The sequence is input so that the drive motor 7 is started with the forward rotation and the reverse rotation.

As shown in FIG. 5, the sintered coke screen is a device that automatically cleans a blockage when a hole in a rubber base having good elasticity is clogged by moisture, and when a coke crushing group is activated, a predetermined time input to a program is provided. When the starter 35, 36, 37, 38 of the rotary roll 30 is activated by the rubber ball 32 attached to the rotary roll 30 by tapping the coke bottom, the screen mat 1 Remove the coal stuck in the hole.

In addition, a program is inputted so that the coke screen rubber mat (1) can be cleaned alone when the hole is excessively clogged.In addition, when the coke incorporated in the COKES BREEZE BIN contains excessive moisture or particle size conditions are inappropriate. When doing so, it prevents the coke screen mat 1 from being blocked and manages it to a certain particle size required by the sintering operation, thereby contributing to productivity and stability of the product.

As described above, according to the present invention, when crushing coke dust collected from anthracite coal or dust collector containing a large amount of water, sedimentation paper during coking hydration, etc. Automatically and continuously cleans the mat hole blockage so that fuel of any condition is sieved on the screen mat to maintain the coke particle size of the volume required in the sintering operation. In this case, the effect of improving the sintering productivity is obtained.
