For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] Combine the following Figures 1 to 6 , describing an embodiment of the utility model.

[0039] According to an embodiment of the utility model, a material iron removal device is provided, comprising:

[0040] The conveying device 2 includes a conveyor belt 22 and a magnetic member 7 fixedly connected to the conveyor belt 22. The conveyor belt 22 is suitable for transporting materials, and the magnetic member 7 is suitable for adsorbing iron parts in the materials onto the conveyor belt 22.

[0041] The conveyor belt 22 is suitable for driving the magnetic member 7 to move, and has a first station along its conveying path for adsorbing the iron member through the magnetic member 7, and a second station for stopping adsorbing the iron member. The iron member is suitable for detaching from the conveyor belt 22 at the second station.

[0042] In the material iron removal device provided in this embodiment, the conveyor belt 22 absorbs the iron pieces at the first station through the magnetic piece 7, and separates from the iron pieces at the second station, so that the surface of the conveyor belt 22 can be cleaned without stopping the iron removal operation, which is beneficial to improving the material iron removal efficiency.

[0043] Specifically, taking the removal of iron impurities in non-pyrophoric fine stone concrete aggregate as an example, the content of iron impurities in concrete aggregate is a key factor affecting its non-pyrophoric performance, and a lower iron impurity content can bring better non-pyrophoric performance. The conveying device 2 also includes a frame 23, and a drive motor 21 fixedly connected to the frame 23, and the drive motor 21 includes an electric motor, a hydraulic motor, and a pneumatic motor. At least one active roller and one driven roller are rotatably connected to the frame 23, and the conveyor belt 22 is sleeved on the active roller and the driven roller. The drive motor 21 is coaxially fixedly connected to the active roller to drive the active roller to rotate relative to the frame 23, so that the active roller drives the conveyor belt 22 to move relative to the frame 23. Preferably, the axis of the active roller and the axis of the driven roller are parallel and located in the same horizontal plane, so that the transportation direction of the conveyor belt 22 is parallel to the horizontal direction. Concrete aggregate is transported as material from the first end of the frame 23 to the second end on the conveyor belt 22. The second end of the frame 23 is fixedly connected with a discharge hopper 5, which is located below the transport plane of the conveyor belt 22 to be suitable for receiving the concrete aggregate transported via the conveyor belt 22.

[0044] Preferably, the magnetic member 7 extends along the width direction of the conveyor belt 22, the number of the magnetic members 7 is greater than one, and the magnetic members 7 are evenly distributed on the conveyor belt 22 along the length direction of the conveyor belt 22. The magnetic member 7 is suitable for adsorbing iron impurities in the concrete aggregate on the conveyor belt 22, so that when the concrete aggregate is transported to the second end of the frame 23 by the conveyor belt 22 and falls into the discharge hopper 5, the iron impurities are adsorbed on the conveyor belt 22 to be suitable for separation from the concrete aggregate body, thereby reducing the iron impurity content of the concrete aggregate falling into the discharge hopper 5, so as to improve the non-fireable performance of the concrete aggregate.

[0045] As the conveyor belt 22 rotates, any point of the conveyor belt 22 has a state where the conveying surface faces upward, and a state where the conveying surface faces downward. Preferably, the second station is arranged at least in a partial area where the conveying surface of the conveyor belt 22 faces downward. Figure 5 As shown, the area corresponding to the second station is area A, and the remaining areas are areas corresponding to the first station. When the magnetic member 7 moves to the second station with the conveyor belt 22, it stops adsorbing iron impurities, so that the iron impurities are separated from the conveyor belt 22 under the action of gravity, thereby avoiding the need to stop the iron removal operation and manually clean the iron impurities on the conveyor belt 22, thereby causing the problem of reduced iron removal efficiency.

[0046] In some embodiments, in combination Figures 1 to 6As shown, the magnetic member 7 includes an electromagnet, which has a power-on state when it moves to the first station to attract the iron member, and a power-off state when it moves to the second station to stop attracting the iron member.

[0047] The material iron removal device provided in this embodiment controls the switching between adsorbing iron parts and stopping adsorbing iron parts by turning the electromagnet on or off, which is easy to operate.

[0048] Specifically, the magnetic member 7 includes an electromagnet and a magnet. Preferably, the magnetic member 7 is an electromagnet, which has a stronger adsorption capacity than a magnet. When the electromagnet is powered on, the iron impurities in the concrete aggregate can be adsorbed on the conveyor belt 22, thereby preventing the iron impurities from following the concrete aggregate into the discharge hopper 5. When the second station is set in the area where the conveyor belt 22 transport surface faces downward, when the electromagnet moves to the second station, the electromagnet is powered off and stops adsorbing the iron impurities, so as to allow the iron impurities to separate from the conveyor belt 22 under the action of gravity, thereby preventing the iron impurities from accumulating on the conveyor belt 22.

[0049] In some embodiments, in combination Figures 1 to 6 As shown, the conveyor belt 22 has a receiving cavity 8 inside, and the electromagnet is located inside the receiving cavity 8 so as to be suitable for moving with the conveyor belt 22 .

[0050] The material iron removal device provided in this embodiment arranges the electromagnet inside the conveyor belt 22 so that the electromagnet moves with the conveyor belt 22 and can avoid direct contact between the electromagnet and iron to increase the cleaning difficulty.

[0051] Specifically, the magnetic member 7 can be arranged on the transport surface of the conveyor belt 22, or on the side of the conveyor belt 22 away from the transport surface, or inside the conveyor belt 22. Preferably, the conveyor belt 22 has a plurality of accommodating chambers 8 inside, the number of accommodating chambers 8 matches the number of electromagnets, each accommodating chamber 8 is provided with an electromagnet, and the size of the accommodating chamber 8 matches the size of the electromagnet, so that the inner wall of the accommodating chamber 8 abuts against the outer wall of the electromagnet, thereby facilitating the formation of a fixed connection between the electromagnet and the conveyor belt 22, and improving the overall stability of the iron removal device. Since the conveyor belt 22 has a plurality of accommodating chambers 8 inside, it is suitable for forming the transport surface of the conveyor belt 22 into a corrugated type, so that the contact between the conveyor belt 22 and the concrete aggregate is more sufficient, the adsorption effect of iron impurities is improved, and the quality of the non-pyrophoric fine stone concrete aggregate produced is better.

[0052] In some embodiments, in combination Figures 1 to 6 As shown, the material iron removal device also includes an electric control device 6, which is electrically connected to the electromagnet so as to control the electromagnet to be powered off when the electromagnet moves to the second working position.

[0053] The material iron removal device provided in this embodiment controls the electromagnet to be powered on or off through the electric control device 6, so as to improve the convenience of operation.

[0054] Specifically, the electric control device 6 is fixedly connected to the frame 23. The electric control device 6 detects whether the electromagnet is in the second working position and controls the power on or off of the electromagnet. The specific position monitoring method and the procedure for controlling the power on and off of the electromagnet are conventional technical means of those skilled in the art, and are not the protection points of the present utility model, and will not be repeated here.

[0055] In some embodiments, in combination Figures 1 to 6 As shown, the material iron removal device also includes a cleaning member 3, which is located at the second station and contacts the surface of the conveyor belt 22 transporting the material, so as to be suitable for cleaning the surface of the conveyor belt 22.

[0056] The material iron removal device provided in this embodiment cleans the conveyor belt 22 through the cleaning member 3 so as to clean off the iron attached to the surface of the conveyor belt 22, thereby improving the cleanliness of the conveyor belt 22 after passing through the second station and reducing labor costs.

[0057] Specifically, the cleaning member 3 contacts the transport surface of the conveyor belt 22 to remove iron impurities attached to the conveyor belt 22, which is beneficial to improving the cleanliness of the conveyor belt 22 after passing through the second station and reducing labor costs. Preferably, the number of cleaning members 3 is greater than one, so as to further improve the cleaning effect.

[0058] In some embodiments, in combination Figures 1 to 6 As shown, the cleaning member 3 comprises a brush.

[0059] Specifically, the cleaning member 3 includes a brush, a cloth, and a flexible plate. The cleaning member 3 is fixedly connected to the frame 23 and contacts the transport surface of the conveyor belt 22. When the conveyor belt 22 passes through the cleaning member 3, the iron impurities attached to the surface of the conveyor belt 22 are swept away by the cleaning member 3, so that the iron impurities on the conveyor belt 22 can be cleaned without stopping the iron removal operation, which is beneficial to improving the iron removal efficiency and reducing labor costs.

[0060] In some embodiments, in combination Figures 1 to 6 As shown, the material iron removal device also includes a collecting box 4, which is located below the second workstation and is suitable for collecting iron pieces swept down by the cleaning piece 3.

[0061] The material iron removal device provided in this embodiment collects the iron pieces separated from the conveyor belt 22 through the collecting box 4, so as to keep the working area of ​​the material iron removal device clean and tidy.

[0062] Specifically, the collection box 4 can be fixedly connected to the frame 23, or it can be placed only under the second station to collect the iron impurities detached at the second station, thereby keeping the working area of ​​the material iron removal device clean and tidy, which is suitable for production occasions with high environmental and civilization requirements.

[0063] In some embodiments, in combination Figures 1 to 6 As shown, the material iron removal device also includes a screening device 1, which is suitable for screening materials. The screening device 1 includes a hopper 11 and a screen 12. The hopper 11 has openings at both ends along the gravity direction. The screen 12 is located at the bottom of the hopper 11 and above the conveyor belt 22, so as to prevent materials with a particle size exceeding a preset value from falling onto the conveyor belt 22.

[0064] The material iron removal device provided in this embodiment screens the material through the screen 12 to prevent the material with a particle size exceeding a preset value from passing through.

[0065] Specifically, the screening device 1 is located above the first end of the frame 23 away from the discharge hopper 5, and the concrete aggregate is poured into the inside through the upper opening of the pouring hopper 11, and falls onto the conveyor belt 22 through the screen 12, wherein the specification of the screen 12 is selected according to the particle size requirement of the required concrete aggregate. As a feasible implementation form, the aperture of the screen 12 is 15 mm. A support frame 14 is fixedly connected between the pouring hopper 11 and the frame 23, and the support frame 14 is suitable for supporting the pouring hopper 11. The material iron removal device provided in this embodiment can screen the aggregate particle size while removing iron from the concrete aggregate, so as to facilitate the aggregate processing work.

[0066] In some embodiments, in combination Figures 1 to 6 As shown, the screen 12 is movably fixedly connected to the pouring hopper 11, and is fixedly connected to the vibrator 13. The vibrator 13 is suitable for driving the screen 12 to vibrate.

[0067] The material iron removal device provided in this embodiment enables the vibrator 13 to drive the screen 12 to vibrate, so as to improve the screening efficiency of the screen 12.

[0068] Specifically, the movable fixed connection between the screen 12 and the dump hopper 11 is a slot-type sliding connection, and the screen 12 can be shaken in the horizontal direction, and the upper end surface of the screen 12 contacts the lower end surface of the dump hopper 11 to prevent the concrete aggregate from leaking from the gap between the screen 12 and the dump hopper 11 to the conveyor belt 22; or, the screen 12 can be shaken in the gravity direction, and the side surface of the screen 12 contacts the bottom of the side wall of the dump hopper 11 to prevent the concrete aggregate from leaking from the gap between the screen 12 and the dump hopper 11 to the conveyor belt 22. The vibrator 13 includes an electric vibrator, a hydraulic vibrator, and a pneumatic vibrator.

[0069] In some embodiments, in combination Figures 1 to 6 As shown, a discharge port 111 is partially formed in the area of ​​the side wall of the hopper 11 near the bottom thereof, and materials with a particle size exceeding a preset value are suitable for leaving the material iron removal device through the discharge port 111 .

[0070] The material iron removal device provided in this embodiment provides a discharge port 111 at the bottom of the side wall of the hopper 11 to prevent materials exceeding a preset particle size from gathering inside the hopper 11 , thereby reducing the screening efficiency of the screen 12 .

[0071] Specifically, concrete aggregates exceeding the preset particle size value can be separated from the screening device 1 through the discharge port 111 under the shaking action of the screen 12, thereby preventing concrete aggregates with too large particle size from accumulating in the hopper 11 and blocking the mesh of the screen 12, thereby affecting the screening efficiency of the screen 12.
