Description

Dual-blade Belt Cleaner Capable of Automatically Controlling Tention Thereof}

The present invention relates to a belt cleaner (Belt Cleaner) used in the belt conveyor (Belt Conveyor). More specifically, two blades for installing two rubbers for removing dust adhering to the belt, and for installing a weight on the body of the belt cleaner to maintain a constant tension between the belts in contact with the rubber. Relates to a belt cleaner.

In general, the belt cleaner is an apparatus used to clean belt conveyors used for transporting raw materials and various transport products in steel mills, cement plants, mines, thermal power plants, chemical plants, and food plants. In the belt conveyor, due to the structural characteristics of carrying various transport materials, a phenomenon in which fine residues of the transport materials adhere to the belt according to the type of transport materials frequently occurs. In particular, when the transport carried by the belt conveyor is coal, a large amount of coal dust is attached to the belt surface of the belt conveyor, and some of the attached dust is transferred to the pulley and the idler and attached to the pulley and Irregularly increases the diameter of the intermediate car.

The dust attached to the pulley and the intermediate vehicle causes the belt of the belt conveyor to bend and rotate and move up and down, causing serious problems that can cause the belt conveyor to stop operating.

In addition, there is a risk of fire caused by the dust falling on the belt from time to time throughout the belt conveyor facility.In particular, the dust falling from the belt is carried by wind and spreads to residential areas, causing civil complaints and causing serious environmental pollution. It caused a big problem. In addition, there is a problem in that the components of the belt conveyor, such as pulleys, intermediate cars and belts are damaged, which is expensive to replace parts. In order to solve these environmental and economic problems, a belt cleaner has been developed for the purpose of always cleaning the belt side of the belt conveyor.

1 is a side view showing a state of use of a conventional belt cleaner.

Referring to FIG. 1, a conventional belt conveyor includes a pulley 102 and a pulley 102 which are installed inside a chute 100 and rotated around the transfer belt 108, the transfer belt 109, and the pulley 102. A belt cleaner 104 having a belt conveyor frame 110 fixed to the center to support the pulley 102, and having a blade 106 contacting the surface of the conveying belt 109, a belt cleaner 104 The belt cleaner support 107 for supporting the 104 is structured to be connected to the belt conveyor frame 110.

Here, the blade 106 has a rubber (Rubber) type of the rubber material and a tip (Tip) type of the light alloy material. The rubber type does not damage the belt due to the nature of the rubber blade, but the blade is badly worn and has to be frequently replaced. On the other hand, since the tip type is made of a light alloy material, the blade does not easily wear, but if the blade is damaged, the belt is broken or the surface is damaged.

Looking at the process of removing the dust 114 from the belt conveyor in the prior art, the belt conveyor is powered by an external power source (not shown) conveys the conveying belt 108 and the conveying belt 109. A transport 112 is placed on the transport belt 108, so that the transport 112 is transported along the moving direction of the transport belt 108. In general, the large particle transporter 112 accumulates in the trap 116 apart from the point where the pulley 102 is located. However, small particles and the like that do not fall down at the point where the pulley 102 is located are removed from the belt surface by the blade 106 attached to the surface of the conveying belt 109.

However, the belt cleaner 104 mounted on the belt conveyor of the related art has a problem that the blade 106 is not properly contacted with the belt surface due to the wear of the blade 106 due to long-term use, so that the cleaning efficiency is greatly reduced.

In addition, in the conventional belt conveyor equipment, two to four cemented carbide tips of the belt cleaner 104 for cleaning are installed at the lower portion of the conveying belt 109, but when the tip wears, the surface pressure of the conveying belt 109 is controlled. It was impossible to clean the dust and the like on the surface of the conveyance belt 109 efficiently. In order to increase the efficiency of cleaning, the belt cleaner 104 may be separately manufactured and installed separately at regular intervals under the conveyance belt 109. However, in this case, the manufacturing cost of the belt cleaner 104 is greatly increased. There is this.

In order to solve the above problems, the present invention comprises a rubber belt of the belt cleaner in two stages in order to remove the residual material adhered to the surface of the conveying belt, by connecting the weight body portion having a load on one side of the belt cleaner and the conveying belt and An object of the present invention is to provide a double-blade belt cleaner having a tension adjustment function for automatically adjusting the tension between rubbers.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

2 is a front view of the belt cleaner 200 to which the bracket 210 is attached according to an embodiment of the present invention.

Referring to FIG. 2, the belt cleaner 200 has the same shape as the shear support holder 208 and the shear support holder 208 having two parallel iron plates spaced at regular intervals, and the shear support holder 208. It has a rear end holder 209 is installed in parallel with a constant interval. The front and rear rubbers 202 and 204 are inserted between both steel plates of the front and rear support holders 208 and 209. The separation distance between two parallel steel plates constituting the front and rear support holders 208 and 209 is larger than the thickness of the front and rear rubbers 202 and 204 so that the front and rear rubbers 202 and 204 can be easily fitted. It is desirable to set it slightly wider.

In the embodiment of the present invention, as the material of the front and rear support holders 208 and 209, the belt cleaner 200 is lightened by changing the weight of the belt cleaner 200 from a conventional stainless steel material to an iron plate material. It was easy to handle. In addition, the horizontal length of the front end holder 208 and the rear end holder 209 changes in proportion to the change in the width of the conveyance belt 109.

On the other hand, in the belt cleaner 200 according to the present invention, both ends are bent toward the front and rear end holders 208 and 209, and portions bent on the respective outer steel plates of the front and rear end support holders 208 and 209. A belt cleaner body 206 attached by welding or the like. A bracket 210 bent at a right angle is attached to the belt cleaner body 206 that is bent at both ends of the rear support holder 209 and is attached in parallel with the rear support holder 209. Is attached. The bracket 210 is coupled to one end of the weight arm 302 to be described later with a bolt.

3 is a perspective view showing a weight portion 300 according to an embodiment of the present invention.

3, the weight part 300 according to the present invention includes a weight 301, a weight arm 305, a hinge hole 306, and a bracket hole 308.

The weight body 301 is in contact with the rear surface of the weight body A 302 and the weight body A 302 which are attached to the end of the weight arm 305 by welding or the like. The weight body B (303), the weight body C (304), and the like, which are bonded together. According to an embodiment of the present invention, the weight body 301 adjusts the tension of the rubber 106 relative to the conveying belt 109 via the weight body 305 so that the rubber 106 contacts the conveying belt 109. This will function well. The principle of automatically adjusting the tension of the weight body 301 will be described in more detail with reference to FIG. 5.

The weight A 302 is basically attached to the weight arm 305, but the weight B 303, the weight C 304, and the like are conveyed when the weight body 300 is first mounted to the belt conveyor facility. It is optionally used to set the contact sensitivity between the belt 109 and the rubber 106 to an optimal state. That is, when the weight part 300 is first installed in the belt conveyor facility, the front and rear rubbers 202 and 204 in contact with the conveying belt 109 can effectively remove dust and the like attached to the conveying belt 109 as efficiently as possible. The load of the weight body 301 is set so that it may be carried out. When the front and rear rubbers 202 and 204 remove dust and the like, and the front and rear rubbers 202 and 204 become in contact with the conveyance belt 109 due to abrasion due to the initial load of the weight 301. The weight unit 300 automatically adjusts the contact sensitivity. This will be described in more detail with reference to FIG. 5.

The hinge hole 306 is formed to couple the weight portion 300 to the belt conveyor facility using bolts.

The hole 308 for the bracket is formed to fix the bracket 210 described in FIG. 2 to the weight arm 305 using a bolt.

4 is a plan view showing a state in which the belt cleaner 200 and the weight body 300 are fastened according to an embodiment of the present invention.

Referring to FIGS. 2 to 4 simultaneously, the belt cleaner 200 and the weight body 300 are not bent and the weight body 300 of the bracket 210 is not attached to the belt cleaner body 206 One end of the weight arm 305 is connected. In more detail, two holes are formed in the bent portion of the bracket 210 not attached to the belt cleaner body 206 and the weight arm 305 to which the weight body 300 is not attached. have. After the weight body 302 and the bracket 210 are brought into close contact with each other so that the two holes formed in the bracket 210 and the two holes for the bracket 308 formed in the weight body 305 coincide with each other, the bolt 400 or the like. The belt cleaner 200 and the weight arm 302 are firmly fixed by tightening using the same.

5 is a side view showing a state of use of the belt cleaner 200 according to an embodiment of the present invention.

Referring to FIG. 5, one side of the bracket 210 and the weight arm 305 is tightened with two bolts 400 so that the weight part 300 coupled with the belt cleaner 200 is a portion of the weight arm 305. Is fixed to the chute outer wall 500 by inserting and tightening a bolt 502 or the like into the hinge hole 306 formed in the weight arm 305 in a bent state. In more detail, in order for the weight part 300 having the weight body 301 having a constant thickness to be installed on the chute outer wall 500, the reference numeral 504 should be bent to have a constant angle with the chute outer wall 500. Sieve 301 is not in contact with chute outer wall 500.

On the other hand, the principle of automatic tension adjustment between the front and rear rubbers 202 and 204 and the conveyance belt 109 according to the embodiment of the present invention is the same as that of the lever.

In more detail, one side on which the weight body 301 is mounted has more load than one side on which the belt cleaner 200 is mounted. Therefore, when a certain point of the weight arm 305 connecting the belt cleaner 200 and the weight body 301 is made a central axis, the weight body 301 is mounted so that one side of the load that is heavier than the other side goes down. , The belt cleaner 200 is mounted so that one side of the lighter load than the opposite side rises up.

That is, even if the front and rear rubbers 202 and 204 wear out over time, smooth contact is continued by the force which continuously acts between the conveyance belt 109 and the front and rear rubbers 202 and 204. Referring to FIG. 5, the point where the bolt 502 is fitted serves as a kind of central axis in view of the principle of the lever.

On the other hand, applying the principle of the lever with the bolt 502 as the central axis, it can be seen that the tension acting on the front rubber 202 is greater than the tension acting on the rear rubber 204. Therefore, in order to smoothly clean the rear rubber 204, the tension applied to the rear rubber 204 is preferably equal to or greater than the tension applied to the front rubber 202.

For this purpose, it is preferable to produce the rear rubber 204 such that the height h 'of the rear rubber 204 is slightly higher than the height h of the front rubber 205. However, if the height of the rear rubber 204 is too high so that the front rubber 202 does not contact the conveying belt 109 properly, the cleaning work such as dust 114 may not be properly performed at the front rubber 202. The height of the rear rubber 204 should be appropriately determined.

Reference numeral 505 denotes a tension acting between the conveyance belt 109 and the front end rubber 202, and reference numeral 506 denotes a tension acting between the conveyance belt 109 and the rear end rubber 204.

On the other hand, in order for the point where the bolt 502 is fitted to function as a central axis, one side on which the weight body 301 is mounted is lowered little by little, and one side on which the belt cleaner 200 is mounted is slightly raised upward by a bolt ( 502) should be properly tightened. That is, if the bolt 502 is too tightly tightened so that one side on which the weight body 301 is mounted does not move at all, the tension between the transport belt 109 and the front and rear rubbers 202 and 204 is not achieved at all. When the rear rubbers 202 and 204 are worn out, cleaning is not performed efficiently.

On the other hand, when the bolt 502 is tightened so weakly that one side on which the weight body 301 is mounted falls down too severely, the tension between the conveying belt 109 and the front and rear rubbers 202 and 204 is too strong. The front and rear rubbers 202 and 204 may damage the conveyance belt 109 or the front and rear rubbers 202 and 204 may bend, which may cause a risk that the cleaning operation itself becomes impossible.

As described above, the belt cleaner according to the present invention has two rubber cleaners to remove dust and dust at the front and rear stages, so that the belt cleaner is installed twice, so that two belt cleaners are installed by installing one belt cleaner. Can be obtained.

In addition, by connecting the weight portion having the weight to the belt cleaner automatically adjusts the tension between the belt and the rubber to prevent the contact between the belt and the rubber due to the wear of the rubber at the source to ensure efficient cleaning at all times It works.
