Description

Technical Field

[0001] The invention relates to the field of mining material conveyors, and in particular to a ferromagnetic material separation device for mining material conveyors. Background Art

[0002] Mining material conveyors are widely used in mines and mining production to transport materials such as ore and coal. However, these materials often contain ferromagnetic impurities, which not only affect the subsequent processing technology, but may also cause damage to the equipment. Therefore, it is necessary to use a ferromagnetic material separation device to separate the ferromagnetic impurities in the material.

[0003] The existing ferromagnetic material separation device for mining material conveyors is arranged above the mining material conveyors. The ferromagnetic impurities on the conveyor are adsorbed onto the conveyor belt by strong magnetic parts, and then the ferromagnetic impurities are moved to the collection frame through the conveyor belt for unloading. However, when the strong magnetic parts adsorb ferromagnetic impurities, non-ferromagnetic materials may be adsorbed on the conveyor belt and separated by mistake, which may easily affect the normal transportation of the conveyor belt and cause material loss.

[0004] Therefore, a ferromagnetic material separation device for a mining material conveyor has been developed, which can cause the conveyor belt to vibrate so as to facilitate the separation of non-ferromagnetic materials from the conveyor belt, reduce misseparation, and improve separation efficiency. Summary of the invention

DETAILED DESCRIPTION

[0033] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0034] A ferromagnetic material separation device for a mining material conveyor, such as Figure 1 and Figure 2 As shown, it includes a mounting plate 1, a first rotating shaft 2, a motor 3, a conveyor belt 4, a force-bearing frame 5, a sorting mechanism 6 and a reinforcing mechanism 7. The left and right parts of the mounting plate 1 are both rotatably connected to the first rotating shaft 2. The front side of the left part of the mounting plate 1 is connected to the motor 3. The output shaft of the motor 3 is connected to the first rotating shaft 2 on the left side. The conveyor belt 4 is wound around the first rotating shafts 2. Six force-bearing frames 5 are connected to the upper side of the mounting plate 1. The force-bearing frames 5 are all in contact with the conveyor belt 4. The mounting plate 1 is provided with a sorting mechanism 6, and the sorting mechanism 6 is provided with a reinforcing mechanism 7.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, the sorting mechanism 6 includes a fixed frame 61, a strong magnetic member 62, a conveyor belt 63, a second rotating shaft 64, a connecting shaft 65, a discharging frame 66, a first belt 67 and a gear 68. The front and rear sides of the mounting plate 1 are connected to the fixed frame 61, and the strong magnetic member 62 is connected between the fixed frames 61. The left and right parts of the fixed frame 61 are rotatably connected to the second rotating shaft 64, and the conveyor belt 63 is wound between the second rotating shafts 64. The strong magnetic member 62 is located inside the conveyor belt 63. The left part of the front fixed frame 61 is rotatably connected to the connecting shaft 65, and the right side of the fixed frame 61 is connected to the discharging frame 66. A baffle is provided on the discharging frame 66 to facilitate guiding the discharging. The discharging frame 66 is located below the conveyor belt 63. The first belt 67 is wound around the connecting shaft 65 and the output shaft of the motor 3 through a transmission wheel. A gear 68 is connected to the connecting shaft 65, and the front side of the second rotating shaft 64 on the left side is also connected to a gear 68, and the gears 68 are meshed with each other.

[0036] like Figure 1 , Figure 5 and Figure 6 As shown, the reinforcing mechanism 7 includes a support member 71, a limit frame 72, a rotating rod 73, a second belt 74, a cam 75, a lower pressure frame 76 and a first spring 77. The upper sides of the left and right parts of the fixed frame 61 are connected to the support members 71, and the limit frames 72 are connected between two laterally adjacent support members 71. The rotating rod 73 is rotatably connected between the middle parts of the limit frames 72. The second belt 74 is wound around the front and rear parts of the rotating rod 73 and the second rotating shaft 64 on the right side through a transmission wheel. The front and rear parts of the rotating rod 73 are connected to the cam 75. The lower pressure frame 76 is slidably connected between the limit frames 72. The lower pressure frame 76 passes through the conveyor belt 63. The left and right parts of the limit frame 72 are connected to the lower pressure frame 76 with a first spring 77.

[0037] When using the present invention, first place the mounting plate 1 in the mining material conveying area, then pour the material to be conveyed onto the conveyor belt 4, then start the motor 3 to drive the first rotating shaft 2 to rotate, so that the conveyor belt 4 rotates to convey the material, and the force frame 5 supports the conveyor belt 4. When the motor 3 is started, it drives the first belt 67 to rotate, so that the connecting shaft 65 rotates to drive the gear 68 to rotate, and the gear 68 meshes and moves, so that the second rotating shaft 64 and the conveyor belt 63 rotate. After the conveyor belt 4 conveys the material to the bottom of the fixed frame 61, the ferromagnetic material is adsorbed on the conveyor belt 63 through the strong magnetic part 62. After the conveyor belt 63 conveys the ferromagnetic material to the right to the discharge rack 66, the ferromagnetic material detaches from the conveyor belt 63 and falls onto the discharge rack 66, thereby separating the ferromagnetic material from the non-ferromagnetic material. When the second rotating shaft 64 rotates, the rotating rod 73 is driven to rotate through the second belt 74, so that the cam 75 rotates to squeeze the lower pressure frame 76, and the lower pressure frame 76 is moved up and down in a small range in the limit frame 72 through the force of the first spring 77, so that the lower pressure frame 76 pushes the conveyor belt 63 to move up and down, thereby causing the conveyor belt 63 to vibrate, so as to facilitate the separation of non-ferromagnetic materials from the conveyor belt 63, reduce erroneous separation, and improve separation efficiency.

[0038] like Figure 1 , Figure 7 and Figure 8 As shown, a vibration mechanism 8 is also included, and the vibration mechanism 8 includes a telescopic rod 81, a second spring 82, a vibration frame 83 and a rotating frame 84. The front and rear parts of the mounting plate 1 are connected with three telescopic rods 81, and the vibration frame 83 is connected between the telescopic ends of the telescopic rods 81. The vibration frame 83 is located below the conveyor belt 4. The second spring 82 is connected between the telescopic rods 81 and the vibration frame 83. The front and rear sides of the second rotating shaft 64 are connected with the rotating frame 84, and the rotating frame 84 is squeezed and matched with the vibration frame 83.

[0039] By using the vibration mechanism 8 of the device, the conveyor belt 4 can be vibrated. When the second rotating shaft 64 rotates, the rotating frame 84 is driven to rotate, so that the rotating frame 84 squeezes the vibration frame 83. Under the action of the second spring 82, the vibration frame 83 moves up and down to squeeze the conveyor belt 4, thereby making the conveyor belt 4 vibrate, facilitating the separation of materials and improving the separation efficiency and accuracy.

[0040] like Figure 1 and Fig. 9 As shown, it also includes a regulating mechanism 9, which includes a support frame 91, a lifting frame 92 and an adjusting rod 93. The support frame 91 is connected to the upper left side of the mounting plate 1, and the lifting frame 92 is slidably connected to the support frame 91. The lifting frame 92 is trapezoidal, which is convenient for fitting the conveyor belt 4. The middle part of the lifting frame 92 is rotatably connected to the adjusting rod 93. The adjusting rod 93 is threadedly connected to the support frame 91, and a knob is provided on the upper side of the adjusting rod 93 for easy grasping.

[0041] By using the regulating mechanism 9 of the device, the flow rate of the material can be regulated. The regulating rod 93 can be rotated to move the regulating rod 93 up and down to adjust the distance between the lifting frame 92 and the conveyor belt 4, thereby regulating the flow rate of the material and ensuring complete separation of the material.

[0042] like Figure 1 and Fig.10 As shown, a scraper mechanism 10 is also included, and the scraper mechanism 10 includes a fixing member 101, a scraper 102 and a third spring 103. The front and rear sides of the discharge rack 66 are connected with fixing members 101, and the scraper 102 is slidably connected between the fixing members 101. The third spring 103 is connected between the fixing members 101 and the scraper 102.

[0043] By using the scraper mechanism 10 of the device, ferromagnetic materials can be scraped off the conveyor belt 63. The scraper 102 is always kept in contact with the conveyor belt 63 through the force of the third spring 103. When the conveyor belt 63 rotates, the scraper 102 scrapes the ferromagnetic materials from the conveyor belt 63 to the discharge rack 66, thereby ensuring that the ferromagnetic materials are separated from the conveyor belt 63.

[0044] like Figure 1 and Fig.11 As shown, the ejection mechanism 11 is also included, and the ejection mechanism 11 includes a fixed seat 111, an electric push rod 112 and a push plate 113. The fixed seat 111 is connected to the right side of the discharge rack 66, and the electric push rod 112 is connected to the fixed seat 111. The push plate 113 is connected to the telescopic end of the electric push rod 112, and the push plate 113 is in contact with the discharge rack 66.

[0045] The ejection mechanism 11 of the device can be used to clean the discharge rack 66, and the electric push rod 112 on the fixed seat 111 is started to move the push plate 113 forward, thereby automatically cleaning the discharge rack 66 and saving manpower.
