Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a non-

The present invention relates to a non-product blocking device and a blocking method, and more particularly, to a non-product blocking device and a blocking method that effectively block non-products such as fine particles or gangue stones generated in a crushing and crushing process at a production site.

 The fine or gangue generated during the crushing process of the steel production site mainly occurs when the coke coking coal is crushed to the proper size in the coal process of the coke plant. Due to the wind pressure generated by the crusher for crushing the winchitan and the rotational force of the crusher, the fine grains and gangue are discharged to the raw material bulkhead, thereby polluting the periphery of the facility. For example, when a hammer crusher is used as a crusher, the crusher is crushed by a rebound plate provided on the inner wall of the hammer crusher and a hammer formed at an end of the shaft rotating at a high speed. That is, in the crushing process, the coke supplied from the crushing section is rotated by the hammer, and the repulsive process in which the coke is broken by the centrifugal force of the hammer and the collision with the rebound plate installed on the inner wall of the crusher is repeated. Shred. Here, the proper particle size means a particle size suitable for use in the steelmaking process. There arises a problem that the fine particles and gangue generated in the crushing process are scattered upward from the lower side of the crusher to the bulkhead due to wind pressure and rotational force of the crusher rotating. This causes pollution problems in the working environment, and the fine particles are dissipated into the air to cause air pollution, and the gangue has a difficulty to pollute the working environment and generate additional costs due to environmental management.

Prior to description of the embodiment of the present invention, a raw material feeding path will be briefly described with reference to Fig. 1 (a).

The raw material input path 100 has a predetermined length extending in a vertical direction in a tubular form and the inside thereof is vertically connected so that the raw material can move, and is divided into an inside and an outside by a wall having a predetermined thickness. In the embodiment of the present invention, a through hole 110 is formed on one side of the wall and a through hole 120 is formed on the other side of the wall opposite to the through hole 110 along the periphery of the wall. . Here, the thickness of the wall depends on the kind of the material to be moved. From the upper side to the lower side of the inside of the material feed path 100, the raw materials move and the non-products (for example, differentiation, gangue) generated in the crushing process from the lower side to the upper side can be raised.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a non-product insulation device according to an embodiment of the present invention will be described.

FIG. 1 is a perspective view of a raw material feeding path, (b) a sectional view of a raw material feeding path to which an obstacle obstructing device according to an embodiment of the present invention is applied, FIG. 2 is a sectional view of the obstacle obstructing device according to the embodiment of the present invention, It is an exploded view.

The non-product screening device is inserted into a plurality of through-holes 110 and 120 provided at positions opposite to each other in a wall of a path 100 in which a raw material is introduced, and is blown upward from the lower side of the inside of the path 100 Blocks non-products (eg, ginseng, gangue).

The non-product shielding device includes a shielding part 200 for shielding the non-product, and a connection part 300 for installing the shielding part 200 in the path 100.

The shielding part 200 includes a shielding plate 210 and a support protrusion 223 provided at the through holes 110 and 120 to be inserted into the through holes 110 and 120 of the path 100, And a support plate 220 for supporting the support plate 210.

The blocking plate 210 is a plate having a predetermined length and extending in one direction (X direction) and has a plurality of through holes 211 at one end thereof, And is fixed to the plurality of through holes 221. Here, the connecting member 212 may be a bolt, a nut, a rivet, or the like. The blocking plate 210 is divided into an insertion region where a part of the blocking plate 210 is inserted into the through holes 110 and 120 provided in the path 100 and a protruding region which protrudes outside the wall of the path 100. Portions of the insertion region abut against each other within the path 100 to form a blocking region 213 that blocks the interior of the path 100. The blocking area 213 will be described in detail in the following non-product blocking method. In addition, the barrier plate 210 has a self-restoring force and retains its original shape without being damaged even if it receives a force within an elastic limit. The blocking plate 210 is made of a flexible member or an elastic member. For example, materials with elasticity such as rubber can be used. The blocking plate 210 shown in FIGS. 1 and 2 is expressed in a streamlined shape in which a lower end portion forms a constant curve. This indicates that the shield plate 210 can be freely bent within a predetermined range. Here, the predetermined range is the range of the force that the blocking plate 210 is not damaged due to warping, that is, the range of the force that the elastic limit of the material can withstand.

The support plate 220 supports the shutoff plate 210 and is a member that is installed on the path 100 and a portion thereof is inserted into the path 100 and the rest is located outside the path 100.

The support plate 220 includes a plate having a predetermined length and a plurality of through holes 221 at one end of the plate and extending in one direction (X direction) And is fixed to the through hole 211. That is, the support plate 220 has the same or similar size as the cutoff plate 210 in one direction (X direction) and a size smaller than the cutoff plate 210 in the direction (Y direction) intersecting the direction. Thereby reliably supporting the upper region of the shield plate 210 and allowing the lower region of the shield plate 210 to flex and bend freely. A protruding support protrusion 223 having a length extending in one direction (X direction) is formed on one side lower side of the plate, and is installed at the lower end of the through holes 110 and 120 provided in the material supply path 100. The description of the mounting of the support jaw 223 will be described in detail in the lower guide 340 of the connection portion 300, which will be described in detail later. Angle adjusting joints 222 (222a, 222b) are formed on both ends of one surface of the support plate 220 in the other direction (Y direction). Each angle adjustment connector 222 (222a, 222b) is rotatably connected with the angle adjustment bolt (320: 320a, 320b) to be described later.

The connection part 300 is fixed to the outside of the wall of the path 100 and is connected to the support plate 220. That is, the connection portion 300 allows the support plate 220 to be installed at a position where the support plate 220 is placed on the path 100. This prevents the non-product isolator from leaving the initial installation position from self-vibrating and external shocks generated during operation of the crusher or crusher. In addition, the space between the blocking portion 200 and the wall of the material feed path 100 is blocked to block the non-produced material that can be discharged to the outside of the path 100.

The connection unit 300 includes a pedestal 310 fixed to the outside of the wall of the path 100 at the lower side of the through holes 110 and 120 provided in the path 100, Angle adjusting bolts 320 and 320a and 320b connecting between the connecting portions 222 and 222a and 222b and an upper guide 330 disposed in a space between the upper side of the blocking portion 200 and the outside of the wall of the path 100, And a lower guide 340 disposed at the lower end of the through-holes 110 and 120.

The pedestal 310 (310a, 310b) has a through hole 311 (311a, 311b) extending in one direction (X direction) and one end of which an angle adjusting bolt 320 (320a, 320b) And a vertical plate connected to one end of the horizontal plate and extending in the vertical direction and fixed to the wall of the path 100. Further, a reinforcing plate formed by joining one surface of the horizontal plate and the lower surface of the horizontal plate in an oblique line is provided to support a load received by the horizontal plate. The overall shape is a '?' Shaped frame of Hangul having a reinforcing plate on the inside. The pedestal 310 (310a, 310b) includes a vertical plate fixed to the wall of the path 100, and a horizontal plate connected to the angle adjusting bolts 320, 320a, 320b to support the load of the blocking portion 200. Here, bolts, nuts, rivets, welding, etc. may be used to fix the vertical plate of the pedestal 310 (310a, 310b) and the wall of the path 100. Also, the path 100 may include a pedestal 310 (310a, 310b) formed by protruding outside the wall. The size of the horizontal and vertical plate areas of the pedestal 310 (310a, 310b) varies with the load received by the horizontal plate.

The angle adjusting bolts 320 are formed in the shape of a circular ring corresponding to the shape of the angle regulating connection portion 222 (222a, 222b) provided in the support plate 220, the length of which is increased in the vertical direction. The round bolt head on the upper side of the angle adjusting bolts 320 (320a, 320b) is rotatably connected to the angle adjusting joints 222 (222a, 222b). For example, the center can be connected by bolts and nuts with no thread and threaded only at one end. The lower side of the angle adjusting bolts 320 is inserted through the through holes 311a and 311b provided in the horizontal plates of the pedestals 310a and 310b and is inserted into the first 322a, 322b disposed on the lower surface of the nut 321 (321a, 321b). Adjusting the first and second nuts 321 and 322 adjusts the length H of the angle adjusting bolts 320 and 320a and 320b and adjusts the distance between the barrier plate 210 and the wall 100 of the path 100, The angle &thetas; the length L of the blocking region 213 in which a part of the insertion region of the blocking plate 210 abuts is changed in accordance with the change of?. For example, when the length of H of the angle adjusting bolts 320 (320a, 320b) is increased by adjusting the first and second nuts 321, 322, the angle between the shield plate 210 and the wall of the path 100, And the length L of the shielding region 213 in which a portion of the insertion region of the shielding plate 210 is abutted is formed becomes longer. That is, the angle at which the interrupting plate 210 is inserted into the path 100 becomes steep and the contact portion of the insertion region increases. On the contrary, when the length of H of the angle adjusting bolts 320 (320a, 320b) is reduced by adjusting the first and second nuts 321, 322, the angle between the shield plate 210 and the wall of the path 100, And the length L of the blocking region 213 in which a part of the insertion region of the blocking plate 210 is abutted is shortened. Here, the length L of the blocking region 213 can be determined according to the weight of the material to be charged and the amount of the charged material. If the amount of the raw material is large, the length of L is shortened so that the raw material does not stagnate at the upper portion of the blocking region 213 and can pass through easily, and if the solid raw material can not pass through the blocking region 213 by the force of gravity, The length of L can be shortened so that it passes through. The length L of the blocking region 213 can be adjusted so that the crushing or crushing operation can proceed without stagnation in consideration of the weight of the raw material and the input amount.

The upper guide 330 has a length extending in one direction (X direction), the outer surface has three surfaces, and the cross section has a triangular shape. At this time, the length is made to correspond to the horizontal length of the cut-off plate 210 and the support plate 220. The upper guide 330 is disposed in the space between the upper side of the shield plate 210 and the wall outer side of the path 100. A space or a clearance is formed between the upper side of the barrier plate 210 inserted into the through holes 110 and 120 provided in the wall of the path 100 and the outer side of the wall of the path 100. The space is increased or decreased as the angle? Between the shield plate 210 that increases or decreases in accordance with the length H of the angle adjusting bolts 320 (320a, 320b) and the wall of the path 100. Since the size of the space or gap is variable, the upper guide 330 uses an elastic member. For example, a soft rubber material having good self-restoring force is used. The upper guide 330, which is disposed in the space, prevents the non-object processing apparatus due to self vibration caused in the crushing or crushing process from being detached from the initial installation position, and the space between the blocking plate 210 and the path 100 wall The gap is covered by the upper guide 330, thereby preventing the risk that the non-product can be discharged into the space or the gap. In addition, direct contact between the barrier plate 210 and the wall of the path 100 is prevented, thereby preventing abrasion and breakage of the barrier plate 210 due to vibration friction generated during operation.

The lower guide 340 has two plates extending in one direction (X direction) perpendicular to each other. Overall, it is in the form of Hangul. The lower guide 340 is disposed between the lower ends of the through holes 110 and 120 and the lower side of the support step 223 provided on the support plate 220. That is, the lower side of the lower guide 340 is disposed above the lower end of the through holes 110 and 120, and the upper side of the lower guide 340 is disposed below the support tabs 223 provided on the support plate 220 do. So that the support plate 220 does not come into direct contact with the through holes 110 and 120. The lower guide 340 is disposed on the lower side of the through holes 110 and 120 to support the support tabs 223 of the support plates 220. The material of the lower guide 340 uses an elastic member so as to perform a buffer function. For example, a soft rubber material having good self-restoring force is used. In addition, it prevents the non-product processing apparatus due to the self-oscillation occurring during the crushing or crushing process from deviating from the initial installation position. In addition, direct contact between the support plate 220 and the wall of the path 100 is prevented, thereby preventing abrasion and breakage of the support plate 220 due to vibration friction generated during operation.

Hereinafter, the non-product blocking method will be described.

FIG. 3 is a flow chart of the non-product blocking method according to an embodiment of the present invention, FIG. 4 is a cross-sectional view of the non-product blocking device at the time of inputting a raw material according to an embodiment of the present invention, Sectional view of the non-product insulation device when the input of the raw material is completed.

A raw material to be used in the production process is prepared (S100). The raw material 500 is a raw material of a solid which can be crushed or crushed to be processed into a proper particle size. For example, it is a solid state raw material such as raw coal in a cocos process.

The raw material is introduced into the raw material feeding path located above the crusher through the moving means (S200). For example, the raw material 500 transferred to the belt conveyor 400 is introduced into the raw material feed path located above the hammer crusher. Referring to FIG. 4, the raw material 500 is introduced into the hammer crusher through the space between the insertion areas 213a and 231b spaced apart from each other by the force of gravity. At this time, the space between the inserting regions 213a and 231b separates the blocking region 213 formed by contacting the blocking plates 210 located inside the path by the gravitational force of the raw material 500, And moves to the inside of the hammer crusher located at the bottom. As shown in FIG. 5, before the raw material 500 is inserted, the blocking plates 210 located inside the path are in contact with each other to form the blocking region 213. Therefore, the blocking region 213 must be adjusted so that the raw material 500 can pass through the blocking region 213 easily. This is accomplished by adjusting the angle between the barrier plate 210 and the walls of the path according to the weight or amount of the charged raw material 500 so that at least a portion of the barrier plates 210 are in contact with each other, The length (length)

Through the above process, the introduction of the raw material 500 is completed (S300). 5, a hammer 730 provided at the end of the hammer shaft 740 connected to the shaft 710 of the hammer crusher 700 and the shaft 710 of the hammer shaft 740 is inserted into the shaft (not shown) 710), and the struck material is repeatedly collided with the rebound plate 750 to be crushed to a proper particle size. During this process, some of the raw materials 600 migrate from the bottom of the hammer crusher to the upstream side, that is, toward the raw material input port. The blocking region 213 provided inside the path blocks movement of the non-produced materials 600. The non-products 600 whose movement is blocked move downward again and move into the hammer crusher and are crushed to a proper particle size.
