Belt conveyor cleaner abnormal state detection device

The present invention relates to a device for detecting an abnormal state of a cleaner for removing dust remaining on the belt surface of a conveyor system for transporting raw materials. The present invention relates to a belt conveyor cleaner abnormality detection device that operates to immediately detect abnormalities of the belt and the cleaner itself, thereby enabling facility protection.

In general, various industrial facilities install and operate a large number of conveyor systems to transfer and transport raw materials. The conveyor system quickly transports large quantities of raw materials (iron ore, coal, limestone, coke, sintered ore, and various parts). It is intended to be composed of many mechanical devices and continuously operated. Especially in large conveyor systems installed outdoors, raw materials are transported through a series of connected conveyors. The raw materials are temporarily stored in chute, hopper, bin, etc. at each conveyor end and then transported to the next conveyor. . In the transportation process of these raw materials, the raw materials attached to the belt should be removed by dust or moisture on the belt of the conveyor to minimize the falling light during operation of the conveyor line to prevent environmental pollution. The additional cost can be reduced.

In order to efficiently remove the dust and raw materials on the belt of the conveyor, a tip cleaner is installed at the lower part of the head pulley that drives the belt to clean the belt. There is a need for a sensing device that can immediately stop the conveyor in the event of a belt abnormality in the conveyor system or an abnormality of the tip cleaner itself, and the sensing device must be reliable to operate correctly at any time.

Conventionally used tip cleaners are configured as shown in Figs. 1 and 2 so that the operation of the tip cleaner is composed of weights 45 to improve the tight contact of the belt 51 of the tip 31, Spring 41 is installed to absorb some splashing during the operation of the belt 51, and it is designed to act as a buffer, and an adjustment lever for managing close contact by wear of the tip 31 and replacement timing of the tip 31 ( 36) is configured to maintain a distance from the attachment stopper bolt 38 to be adjustable by inspection by the inspector.

However, in the situation where a large number of conveyors are installed and operated, and the inspector is not checked at any time due to lack of personnel, accurate tip state management is impossible. 51) Cleaner damage due to tip cleaner jamming due to exposure of steel cord 54 due to abrasion, total length loss of belt 51 due to suspension part 34, suspension liner, etc. The large number of accidents such as the tip cleaner, the belt is damaged, or broken, while being caught by the head pulley, there is a problem that a huge economic loss and equipment shutdown occurs.

The present invention has been made to solve the problems of the conventional tip cleaner in view of the above situation, by using the principle of magnetic proximity switch non-contact belt conveyor that can operate accurately without being affected by the surrounding environment such as rainwater or dust at all It is an object of the present invention to provide a cleaner abnormality detection device.

4 is an operation principle of the belt conveyor cleaner abnormal state detection device of the present invention, Figure 5 is a sectional view of the belt conveyor cleaner abnormal state detection device of the present invention, Figure 6 is a perspective view of the belt conveyor cleaner abnormal state detection device of the present invention, Figure 4 As shown in Fig. 5, the main cover part 8 has a vibrating glass tube in the center and a fully molded conductor 1 having a lead made of two magnetic alloys. And the magnet 2 having permanent magnets N and S built therein is fixed to the base 3 so as to be within the operating region of the magnetic proximity switch. In the magnetic proximity switch, when there is an external magnetic field (magnet) 2, the two leads (conductors) 1 have a magnetic field so that the ends of the leads are opposite to each other, and suction force inversely proportional to the square of the distance is generated. This force causes the two leads in the vacuum tube to contact the contacts by the snap action.

The moving board 11 made of a magnetic material capable of breaking the magnetic field between the conductor 1 and the magnet 2 is configured as follows so that the contact of the magnetic proximity switch can be frequently opened and closed.

A “□” shaped hole is formed in the center of the movable keyboard 11 so that the conductor 1 and the magnet 2 are disposed at the center so as to be in a straight line, and the sensing device can accurately move the movable keyboard 11 up and down. U uneven type movable keyboard guides 19 and 20 are installed on the left and right sides of the main body 7, and the left guide 19 has a structure that can be mounted and taken out to facilitate insertion and withdrawal of the movable keyboard 11. .

On the other hand, after the movable plate 11 is operated up and down, the movable plate 11 is fixed by magnetic force by the magnets 2, which are permanent magnets (N) and (S), but is prevented from moving to the original position due to factors such as external force. In order to form the movable plate fixing groove (16 '), (17') and the sensing device body (7) is pressed to move up and down when moving the moving plate 11, the moving plate fixing device (16) , Install (17).

If a very large external force is applied to the cleaner part due to abnormal conditions such as wear of the tip cleaner of the tip cleaner, bending of the suspension part 34, damage of the cleaner set, and exposure of the steel cord 54 of the belt 51, 45 is up and down oscillation, and the vibration change is transmitted to the adjustment lever 36, so that the adjustment lever 36 is fixed to one side of the movable plate operating lever 14 for moving the movable plate 11 up and down. And a fixing groove 21, 21 'which can be made, and a rotating part 22 capable of freely moving the movable keyboard 11 up and down on the other side, and sensing of which the movable keyboard operating lever 14 is connected. The packing member 15 is inserted into the apparatus main body 7 so that the movable keyboard operating lever 14 can be operated up and down smoothly.

7 is a diagram illustrating the use of the belt conveyor cleaner abnormal state detection device of the present invention. When an abnormal state occurs in the tip cleaner set and the belt, the vertical vibration range of the weight 45 is generated by an external force, and the vibration displacement is adjusted. Since the movable keyboard 11 is moved up or down in the sensing device body 7 through the movable keyboard operating lever 14, the conductor 1 and the magnet 2 are blocked.

As a result, the magnetic field generated from the magnet 2 is not transmitted to the conductor 1, so that the lead contact in the glass tube inside the conductor 1 falls, so that the sensing device is turned off and the driving motor of the conveyor system is turned off. Stopped.

After that, when the movable plate 11 is moved to the center position by the movable plate operating lever 14 to return to the normal state, the lead contact in the glass tube in the conductor 1 is connected by the magnetic field generated by the magnet, and the sensing device is As it is turned on, the conveyor system is running again.

The present invention, which works as described above, is installed in a vacuum tube inside a fully molded conductor so that accurate operation is possible without being influenced by external environment such as rainwater or dust, and a large amount of conveyor is installed and lack of personnel. As a result, early detection of tip cleaner wear, breakage, and electric power loss caused by belts due to the inability to check at any time has the advantage of minimizing enormous economic loss and equipment downtime.
