Description

Technical Field

[0001] The utility model relates to the technical field of stone material iron removal, in particular to a stone material conveyor belt iron removal device. Background Art

[0002] The stone conveyor belt is mainly used to transport the stone after initial crushing in order to facilitate the subsequent crushing or other processing. There are often some iron materials mixed in the stone, so an iron removal device is needed to absorb the mixed iron materials.

[0003] The China Patent Network discloses an iron removal device for garbage pretreatment (Announcement No.: CN 113967534A), which belongs to the field of garbage treatment technology. The key points of its technical solution include a conveyor belt, an iron removal device and a collection box. The iron removal device is located above the end of the conveyor belt, and the collection box is located on the right side of the end of the conveyor belt. The iron removal device includes a frame. When the wire rope is wound, the iron removal device is driven to rise, and conversely, when the wire rope is slowly released, the iron removal device is driven to descend. When the iron removal device descends, the closer the distance to the conveyor belt is, the higher the magnetic force of the excitation system is. When the iron removal device rises, the magnetic force of the excitation system is reduced, thereby facilitating the control of the overall adsorption capacity of the iron removal device, facilitating adjustment according to actual conditions, improving the iron removal rate, and making the incinerator run stably. The existing iron removal device is usually fixedly installed, in which the height adjustment of the suspended iron remover is inconvenient, resulting in the inability to effectively remove some magnetic metals at the upper end of the conveyor belt, thereby affecting the stable operation of the boiler.

[0004] It can be seen from the above technology that the existing self-unloading iron removal device adsorbs iron impurities on the surface of the conveyor belt through magnetic force. As the conveyor belt moves, when the iron impurities leave the magnetic range, they fall directly into the collection box. There are the following defects in use: 1. After the conveyor belt has been transporting the adsorbed iron impurities for a long time, due to the collision and friction between the iron impurities on the conveyor belt, the iron powder that falls due to the collision of the iron impurities is easy to produce magnetism and adhere to the surface of the conveyor belt. If it is not cleaned, it is easy to reduce the iron removal efficiency; 2. The above technology can adjust the height, but it is not convenient to adjust the angle of the iron removal device. When used in inclined transportation, it is not convenient to keep it parallel to the conveyor belt, which affects the iron removal efficiency; therefore, there is room for improvement. Utility Model Content

[0005] The utility model provides a stone conveyor belt iron removal device to solve the problems raised in the background technology.

[0006] In order to solve the above problems, the utility model provides a stone conveyor belt iron removal device, comprising a conveyor belt body and an iron removal device, wherein the iron removal device is horizontally arranged above the conveyor belt body, and the iron removal device is composed of a mounting frame, a motor, a conveyor belt, and a magnetic disk. A roller shaft is rotatably provided in the left and right ends of the mounting frame respectively, and the conveyor belt is sleeved on the two roller shafts in the mounting frame. One end of the roller shaft located on the left side of the mounting frame rotates through the rotating shaft to the outside of the mounting frame, and a first flywheel is installed at the end of the rotating shaft. The motor is arranged on the upper part of the left end of the mounting frame, and is connected to the conveyor belt through the belt. The first flywheel is connected, the magnetic disk is installed in the mounting frame through the support frame, and is located in the conveyor belt and conflicts with the inner side surface of the lower part of the conveyor belt. The magnetic disk is located directly above the conveyor belt body and has the same width as the conveyor belt body. A roller with a hollow interior is rotated on the right side of the roller shaft at the right end of the mounting frame. One end of the roller rotates through the shaft to the outside of the mounting frame, and a second flywheel is installed on the end of the shaft. The second flywheel is connected to the first flywheel through a belt, and a plurality of groups of bristles are provided on the surface of the roller, and the top of the bristles conflicts with the surface of the conveyor belt.

[0007] Preferably: the bottom of the mounting frame in the iron removal device is provided with four supporting legs, and a hydraulic telescopic rod is installed at the bottom of each supporting leg, and the hydraulic telescopic rod is fixedly installed on the conveyor belt body.

[0008] Preferably: the end of the drum rotating away from the second flywheel is provided with a connecting pipe connected to the inside of the drum, and the connecting pipe is connected to a high-pressure fan, and the outer surface of the drum is provided with a plurality of groups of air jets connected to the inside, and each group of air jets is located between two groups of bristles.

[0009] The beneficial effects of adopting the above technical solution are:

[0010] 1. The iron removal device can be installed in the conveyor belt body through the hydraulic telescopic rod and the supporting legs of the mounting frame, and the iron removal device and the conveyor belt body are parallel. The parallel height between the iron removal device and the conveyor belt body can be adjusted by lifting and lowering the hydraulic telescopic rod, thereby ensuring the iron removal efficiency.

[0011] 2. Through the horizontal setting of the iron removal device, the first flywheel can be driven by the belt driven by the motor to rotate, thereby driving the roller on the left side of the mounting frame to rotate, so that the conveyor belt moves. The iron impurities are adsorbed to the conveyor shaft through the movement of the conveyor belt and the suction of the magnetic disk. As the conveyor belt moves, they are discharged from the conveyor belt body. Since the magnetic disk has the same width as the conveyor belt body, when the iron impurities move to the outside of the conveyor belt body, the magnetic force disappears and the iron impurities adsorbed on the conveyor belt fall off.

[0012] 3. The drum rotates through the second flywheel and the belt when the first flywheel rotates. The high-pressure fan is used to send air into the drum, and the air jet is used to blow air to the surface of the transmission belt to blow away the iron filings adhering to the surface of the conveyor belt. Then, the surface of the conveyor belt is cleaned with a brush to sweep away the blown iron filings, so that the surface of the conveyor belt of the iron removal device is always kept clean to improve the iron removal efficiency. At the same time, the surface of the conveyor belt can be cleaned without stopping the machine, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
