Description

Technical Field

[0001] This utility model relates to the field of coal transportation technology, specifically to a metal removal device for material belt conveyors. Background Technology

[0002] Currently, magnetic iron separators are generally used in material belt conveyors. For example, a coal iron removal device described in utility model patent application CN201920982892.8 includes a conveyor consisting of a conveyor belt, a main shaft, and a motor, and further includes: a coarse iron removal component, which uses a magnetic conveyor belt to adsorb large iron particles in the coal and collects them in a collection box; a lifting component, used to intermittently lift the conveyor belt; a linkage component, which drives the magnetic conveyor belt to rotate and the moving bar to move up and down reciprocally during the rotation of the conveyor belt; a fine iron removal component, used to collect fine iron particles in the coal and collect them in the collection box; and a transmission component, used to drive the opposing rotation of separation roller one and separation roller two through the rotation of the magnetic conveyor belt.

[0003] However, iron separators can only remove magnetic metals. The conveyed materials, especially coal, often contain non-magnetic metals, such as tungsten carbide drill bits and high manganese steel. These types of iron separators are difficult to remove such non-magnetic metals. Therefore, this application proposes a metal removal device for material belt conveyors to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a metal removal device for material belt conveyors, in order to solve the problem mentioned in the background art that existing iron removers can only remove magnetic metals, while they are difficult to remove non-magnetic metals that are often mixed in with the conveyed materials, especially coal.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal removal device for material belt conveying, comprising a belt conveyor, a drive cover installed on the outer wall of one end of the belt conveyor, an asynchronous motor installed on the inner wall of the drive cover, frames installed on both sides of the belt conveyor, support feet installed at the lower end of the frames, a support frame installed on the outer wall of one side of the frame, an electrical distribution box installed on the outer wall of the support frame, an actuator installed on the inner wall of the support frame, and a vibrating screen mechanism installed on the outer wall of the other side of the frame.

[0006] Preferably, the actuator includes an L-shaped support plate, a motor base is provided above the L-shaped support plate, a servo motor is installed at the rear end of the motor base, the output end of the servo motor passes through and extends to the front end of the motor base, and a roller bushing is installed on the outer wall of the output end of the servo motor, and rollers are provided on the outer wall of the roller bushing, and three rollers are provided. A metal detector is installed below the L-shaped support plate.

[0007] Preferably, a guide plate bracket is installed at the upper end of the frame, and an arc-shaped guide plate is installed at the upper end of the guide plate bracket.

[0008] Preferably, the output end of the servo motor is equipped with a bearing housing, the lower end of the bearing housing is equipped with a bearing support plate, and both ends of the bearing support plate are connected to the arc-shaped guide plate by bolts.

[0009] Preferably, reinforcing rods are installed above both ends of the arc-shaped guide plate, and the reinforcing rods are connected to the arc-shaped guide plate by bolts.

[0010] Preferably, the vibrating screen mechanism includes a vibrating frame, a screen plate is installed inside the vibrating frame, a material storage box is provided below the screen plate, a metal foreign object collection box is provided at the front end of the material storage box, a vibrating motor is installed on the outer wall of one side of the vibrating frame, supports are installed at both ends of both sides of the vibrating frame, a spring mechanism is installed at the lower end of the support, and a support foot is provided below the spring mechanism.

[0011] Preferably, a pressure-sensing pad is installed between the support leg and the spring mechanism.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model uses a metal detector to detect metal bodies in the conveyed raw materials. If a metal body is detected, the servo motor in the actuator is driven to run. The output end of the servo motor is equipped with a roller bushing. Three rollers are evenly distributed at 120° on its outer wall. The roller head has a certain arc. When rotating, the material in the front detection section along with metal impurities can be pushed out of the belt. Through physical discharge, any metal foreign matter in the material can be effectively removed. This solves the problem that the existing iron remover can only remove magnetic metals. The conveyed material, especially coal, often contains non-magnetic metals such as tungsten carbide drill bits and high manganese steel. For such non-magnetic metals, this type of iron remover is difficult to remove.

[0013] (2) The material pushed out by this utility model can fall into the vibrating screen mechanism on the side. During the vibration process, the material vibrates and moves along the screen plate. Because the coal raw material has a small particle size, it falls down along the screen plate to the material storage box under the vibration action. The tungsten carbide drill bit and high manganese steel mixed in it fall into the metal receiver below along the end of the screen plate to complete the screening and collection.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figure 1-4This utility model provides an embodiment of a metal removal device for a material belt conveyor, comprising a belt conveyor 1, a drive cover 4 mounted on the outer wall of one end of the belt conveyor 1, an asynchronous motor 401 mounted on the inner wall of the drive cover 4, frames 2 mounted on both sides of the belt conveyor 1, support feet 3 mounted on the lower end of the frames 2, a support frame 8 mounted on the outer wall of one side of the frame 2, a distribution box 9 mounted on the outer wall of the support frame 8, an actuator 10 mounted on the inner wall of the support frame 8, and a vibrating screen mechanism 11 mounted on the outer wall of the other side of the frame 2. The actuator 10 includes an L-shaped support plate 101, a motor base 102 disposed above the L-shaped support plate 101, a servo motor 103 mounted at the rear end of the motor base 102, the output end of the servo motor 103 penetrating and extending to the front end of the motor base 102, and a support foot 3 mounted on the outer wall of the output end of the servo motor 103. There is a roller bushing 104, and rollers 105 are provided on the outer wall of the roller bushing 104. There are three rollers 105. A metal detector 108 is installed below the L-shaped support plate 101. A guide plate bracket 5 is installed at the upper end of the frame 2. An arc-shaped guide plate 6 is installed at the upper end of the guide plate bracket 5. The vibrating screen mechanism 11 includes a vibrating frame 111. A screen plate 112 is installed inside the vibrating frame 111. A material storage box 12 is provided below the screen plate 112. A metal foreign object collection box 13 is provided at the front end of the material storage box 12. A vibrating motor 113 is installed on the outer wall of one side of the vibrating frame 111. Supports 114 are installed at both ends of both sides of the vibrating frame 111. A spring mechanism 115 is installed at the lower end of the support 114. A support foot 117 is provided below the spring mechanism 115. A pressure sensing pad 116 is installed between the support foot 117 and the spring mechanism 115. In operation, the coal is conveyed by the belt conveyor 1. When the material reaches the actuator 10, the metal detector 108 below the actuator 10 scans the material to detect whether it contains metal objects. If a metal object is detected, the servo motor 103 is further driven to run. The output end of the servo motor 103 is equipped with a roller bushing 104, on which three rollers 105 are evenly distributed at 120° on the outer wall. The head of the rollers 105 has a certain curvature, and when rotating, it can push the material from the previous detection section along with metal impurities out of the belt. The material is pushed into the vibrating screen mechanism 11 on the side. At this time, the pressure sensing pad 116 of the vibrating screen mechanism 11 detects the pressure change and drives the vibrating motor 113 to run. Because the vibrating screen mechanism 11 has an inclined screen plate 112, the material vibrates and moves along the screen plate 112 during the vibration process. Because the coal raw material has a small particle size, it falls down along the screen plate 112 to the material storage box 12 under the action of vibration. The tungsten carbide drill bit and high manganese steel mixed in fall into the metal collector 5 below along the end of the screen plate 112 to complete the screening and collection.

[0017] Please see Figure 2The output end of the servo motor 103 is equipped with a bearing housing 106, and the lower end of the bearing housing 106 is equipped with a bearing support plate 107. The two ends of the bearing support plate 107 are connected to the arc-shaped guide plate 6 by bolts.

[0018] Please see Figure 1 A reinforcing rod 7 is installed above both ends of the arc-shaped guide plate 6, and the reinforcing rod 7 is connected to the arc-shaped guide plate 6 by bolts. The arc-shaped guide plate 6 can prevent the material from sliding down the sides during the conveying process, and it fits the shape of the roller 105. When pushing the material, it can guide the material into the vibrating screen mechanism 11.

[0019] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
