Description

Technical Field

[0001] The utility model relates to the technical field where magnets cannot move, and particularly relates to an iron removal device for raw materials in preparation. Background Art

[0002] The water stable layer is short for the cement stabilized macadam layer. Cement stabilized macadam uses graded crushed stone as aggregate, adopts a certain amount of cementitious materials and sufficient mortar volume to fill the voids of the aggregate, and is paved and compacted according to the interlocking principle. With the acceleration of the urbanization process and the continuous increase in traffic flow, the requirements for road infrastructure are getting higher and higher. As a reliable base material, the water stable layer can improve the bearing capacity and stability of the road surface, extend the service life of the road surface, and also has advantages such as environmental protection and energy conservation, meeting the requirements for safety and smoothness of traffic arteries such as highways. Therefore, it is widely used in road construction. After the graded crushed stone crushing operation is completed during the preparation of the water stable layer, the iron impurities doped in it will directly enter the production together with the crushed stone. During the preparation of cement stabilized macadam, on the one hand, the iron impurities will cause damage to relevant production equipment, and on the other hand, they will also affect the performance of the cement stabilized macadam after preparation.

[0003] The existing iron removal device in the preparation of water stable layer raw materials is usually during the conveying process after the graded crushed stone crushing operation. A large electromagnet is suspended above the conveyor belt to adsorb iron blocks. Since the position of this type of iron removal device is fixed, usually after the iron removal operation and the collection of crushed stone, the electromagnet is reversely magnetized to make the iron impurities fall and be output by the conveyor belt. Therefore, this type of iron removal device cannot clean the iron blocks adsorbed on the surface of the electromagnet in time. Long-term operation will cause a large amount of iron blocks to be adsorbed on the surface of the electromagnet, affecting the heat dissipation of the electromagnet and also reducing the magnetic force of the electromagnet, thus affecting the normal operation of the electromagnet and reducing the iron removal effect. Therefore, there is an urgent need to design an iron removal device that can clean the iron blocks adsorbed on the surface of the electromagnet in time. Content of the Utility Model

[0027] Please refer to Figures 1-5 , the present utility model provides a technical solution: a device for removing iron from raw materials in preparation, including a crushing material conveyor belt body 1, a crushing material conveyor belt 2, a crushing material conveyor belt receiving port 3, and a crushing material conveyor belt driving motor 4. The graded crushed stone in the preparation of the water-stable layer raw materials is transported to the next-level iron removal operation through the crushing material conveyor belt receiving port 3 and the crushing material conveyor belt body 1. A first iron slag collection box 6 is arranged on the left side of the crushing material conveyor belt body 1, and a second iron slag collection box 7 is arranged on the right side of the crushing material conveyor belt body 1;

[0028] Among them, four support blocks 8 are fixedly connected to the surface of the crushing material conveyor belt body 1, fixing plates 9 are fixedly connected to the upper surfaces of the four support blocks 8, sliding grooves 10 are formed on the surfaces of the fixing plates 9, an iron removal device is arranged on the top of the crushing material conveyor belt body 1, and a vibrating device is arranged inside the crushing material conveyor belt body 1.

[0029] Furthermore, the iron removal device includes an electric telescopic rod 11, the electric telescopic rod 11 is fixedly connected to the surface of the fixing plate 9, the output end of the electric telescopic rod 11 is fixedly connected to a first sliding block 12, a connecting block 13 is fixedly connected to the surface of the first sliding block 12, a second sliding block 14 is fixedly connected to the end of the connecting block 13 away from the first sliding block 12. Both the first sliding block 12 and the second sliding block 14 are slidably connected to the sliding groove 10. A first electromagnet 16 is fixedly connected to the end of the first sliding block 12 close to the crushing material conveyor belt body 1, and a second electromagnet 15 is fixedly connected to the end of the second sliding block 14 close to the crushing material conveyor belt body 1.

[0030] Further, the rapping device includes two rapping vibrators 17, which are respectively fixedly connected to both sides inside the main body 1 of the crushed material conveyor belt. Fixed rings 18 are fixedly connected to the output ends of the two rapping vibrators 17. Two fixed columns 19 are fixedly connected inside the fixed rings 18. Cylindrical sleeves 20 are rotatably sleeved on the surfaces of the two fixed columns 19, and the cylindrical sleeves 20 are in contact with the crushed material conveyor belt 2.

[0031] Further, a controller 5 is fixedly connected to the right surface of the main body 1 of the crushed material conveyor belt. The driving motor 4 of the crushed material conveyor belt is electrically connected to the controller 5. The electric telescopic rod 11, the two rapping vibrators 17, the first electromagnet 16, and the second electromagnet 15 are all electrically connected to the controller 5.

[0032] Further, when using this device, during the iron removal operation, the two rapping vibrators 17 are started through the controller 5. When the amount of iron filings adsorbed on the surface of the second electromagnet 15 reaches a certain amount, the electric telescopic rod 11 is started to contract through the controller 5. Through the first sliding block 12, the connecting block 13, and the second sliding block 14, finally the second electromagnet 15 is moved to the top of the first iron slag collection box 6, and the first electromagnet 16 is moved above the conveyor belt for iron absorption operation. Then, the controller 5 controls the second electromagnet 15 to demagnetize to release and recycle the iron filings. After the release and recycling of the iron filings are completed, the controller 5 controls the second electromagnet 15 to be magnetized. When the amount of iron filings adsorbed on the surface of the first electromagnet 16 reaches a certain amount, the electric telescopic rod 11 is started to extend through the controller 5. Through the first sliding block 12, the connecting block 13, and the second sliding block 14, finally the second electromagnet 15 is moved above the conveyor belt for iron absorption operation, and the first electromagnet 16 is moved to the top of the second iron slag collection box 7 for the release and recycling operation of the iron filings. In this way, the first electromagnet 16 and the second electromagnet 15 alternate reciprocally. The use of this device can effectively perform iron removal operation on the crushed material on the conveyor belt, and can also effectively clean the iron blocks adsorbed on the surface of the electromagnet in a timely manner, avoiding the situation that a large amount of iron blocks are adsorbed on the surface of the electromagnet during long-term operation, which affects the heat dissipation of the electromagnet, reduces the magnetic force of the electromagnet, affects the normal operation of the electromagnet, and reduces the iron removal effect, ensuring the iron removal rate of the electromagnet and reducing the failure rate of the iron removal equipment.

[0033] Further, when using this device, during the iron removal operation, the two rapping vibrators 17 are started through the controller 5. Through the mutual cooperation of the fixed rings 18, the fixed columns 19, and the cylindrical sleeves 20, the two rapping vibrators 17 can effectively vibrate the conveyor belt, and then the crushed materials vibrate accordingly. The use of this device can make the iron filings doped in the crushed materials at the bottom of the conveyor belt be fully adsorbed by the electromagnet, improving the iron removal rate of the electromagnet and enhancing the practicability.

[0034] Further, when using this device, the cylinder sleeve 20 is circular, and the cylinder sleeve 20 is rotatably sleeved on the fixed column 19. The use of this circular cylinder sleeve 20 and the fixed column 19 can effectively reduce the friction between the cylinder sleeve 20 and the conveyor belt, avoiding the situation that when the vibrator 17 vibrates the conveyor belt through the fixing ring 18, the fixed column 19 and the cylinder sleeve 20, the cylinder sleeve 20 generates a large friction force on the conveyor belt, wearing the conveyor belt or even hindering the movement of the conveyor belt. This improves the practicability, extends the service life of the conveyor belt, and reduces the failure rate of the conveyor belt.

[0035] Working principle: When performing the iron removal operation, the two vibrators 17 are started through the controller 5. When the amount of iron filings adsorbed on the surface of the second electromagnet 15 reaches a certain amount, the electric telescopic rod 11 is started to contract through the controller 5. Through the first sliding block 12, the connecting block 13 and the second sliding block 14, the second electromagnet 15 is finally moved to the top of the first iron slag collection box 6, and the first electromagnet 16 is moved above the conveyor belt to perform the iron absorption operation. Then, the controller 5 controls the demagnetization of the second electromagnet 15 to release and recycle the iron filings. After the release and recycling of the iron filings are completed, the controller 5 controls the magnetization of the second electromagnet 15. When the amount of iron filings adsorbed on the surface of the first electromagnet 16 reaches a certain amount, the electric telescopic rod 11 is started to extend through the controller 5. Through the first sliding block 12, the connecting block 13 and the second sliding block 14, the second electromagnet 15 is finally moved above the conveyor belt to perform the iron absorption operation, and the first electromagnet 16 is moved to the top of the second iron slag collection box 7 to perform the release and recycling operation of the iron filings. In this way, the first electromagnet 16 and the second electromagnet 15 can perform reciprocating and alternating operations.

[0036] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the gist of the present invention.
