Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic iron removal, in particular to an intelligent iron removal system for conveying materials. Background Art

[0002] Iron remover is an iron removal device that can generate a strong magnetic field attraction. It is widely used in metallurgy, electricity, mining, chemical industry, glass, cement, building materials, food and other industries. Its function is to remove ferromagnetic impurities mixed in non-magnetic materials. Installing an iron remover on the production line can ensure the safe and smooth operation of mechanical equipment such as crushers and grinders in the material conveying system, and effectively prevent accidents such as iron parts scratching the conveyor belt. Ensure the personal safety of production line workers and improve production efficiency at the same time.

[0003] According to the different magnetic sources, the iron remover can be divided into two categories: electromagnetic iron remover and permanent magnetic iron remover. For the bulk materials transported by the belt conveyor, by installing the iron remover above the belt conveyor, the ferromagnetic debris in the material can be sucked out to achieve the purpose of automatic iron removal.

[0004] According to different iron unloading methods, the iron remover can be divided into manual unloading, automatic unloading and program-controlled unloading. When the ferromagnetic impurities on the surface of the iron remover accumulate to a certain amount, the iron remover stops working and the on-site personnel manually clean the ferromagnetic impurities on the surface of the iron remover. This method has high labor intensity, high labor costs, low conveying efficiency, and it is easy for the ferromagnetic impurities to return to the conveyed materials during the cleaning process, affecting the product quality and the safe operation of the equipment. Automatic unloading iron removers are usually heavy, complex in structure, high in operating energy consumption, and high in later maintenance costs.

[0005] The Chinese patent application with application publication number CN 113333332 A discloses an "intelligent iron removal system and process", which includes a detection component, a measuring component and a controller. The detection component includes a conveyor belt for conveying the material to be ironed, and a metal detector is arranged on the conveyor belt. The measuring component includes an iron remover and a weighing sensor, and the weighing sensor is used to detect the real-time weight of the iron remover when it is in working state. The controller is respectively connected to the metal detector, the weighing sensor and the iron remover signal. The intelligent iron removal system and process solve the problems of manual monitoring, high power consumption and potential safety hazards in production work in the prior art. However, the iron remover is arranged on a rail trolley. When unloading iron, the conveyor belt needs to stop conveying. It can only be restarted when the rail trolley carries the iron remover to the unloading point to complete the unloading and return to the top of the conveyor belt. If the unloading point is far away, it will seriously affect the working efficiency of the conveyor belt. If the unloading point is located on one side of the conveyor belt, although the moving distance of the rail trolley is short, it needs to be transported twice to recover the unloaded ferromagnetic material to the designated location. In addition, the rail trolley occupies a large upper space and is not suitable for certain production operation environments. Summary of the invention

[0006] The utility model provides an intelligent material conveying and iron removal system, which adopts a fixed electromagnetic iron remover in conjunction with a lifting tray AGV trolley to realize online rapid iron unloading of the electromagnetic iron remover.

[0026] Furthermore, the weighing sensor 1 and the electromagnetic iron remover 2 are detachably connected via a hanging device.

[0027] Furthermore, an iron unloading position is provided on one side of the belt conveyor 3 corresponding to the electromagnetic iron remover 1; a limit device 1 8 and a limit device 2 9 are provided on both sides above the belt conveyor 3 and below the electromagnetic iron remover 2, and the signal output ends of the limit device 1 8 and the limit device 2 9 are connected to the control system 5.

[0028] Furthermore, the lifting mechanism 42 is a hydraulic lifting mechanism, which is composed of a base, a hydraulic cylinder and a scissor support, and the base is connected to the pallet mechanism 43 through the hydraulic cylinder and the scissor support.

[0029] Furthermore, the base is detachably connected to the AGV chassis 41 .

[0030] Furthermore, the tray mechanism 43 is composed of a guide rail base, a tray and a tray driving device; guide rails are arranged on both sides of the guide rail base, and sliders are correspondingly arranged on both sides of the tray to cooperate with the guide rails to achieve a sliding connection; the tray driving device is a pulley, which is embedded in the guide rail and is used to drive the tray to move along the guide rail.

[0031] Furthermore, the guide rail base is detachably connected to the lifting mechanism 42 .

[0032] The working process of the intelligent material conveying and iron removal system described in the utility model is as follows:

[0033] 1) When the belt conveyor 3 carries the material 6 mixed with ferromagnetic impurities 7 and passes under the electromagnetic iron remover 2, the electromagnetic iron remover 2 is in an excitation state and absorbs the ferromagnetic impurities 7 in the material 6; the weighing sensor 1 monitors the weight of the ferromagnetic impurities 7 absorbed by the electromagnetic iron remover 2 in real time, and when the measured weight value reaches the set weight upper limit, the lifting pallet AGV trolley 4 is started through the control system 5;

[0034] 2) The lifting pallet AGV trolley 4 moves along the set route. When the lifting pallet AGV trolley 4 reaches the unloading position and the limit device 8 detects that the pallet is at the initial position, it transmits a signal to the control system 5. The control system 5 controls the belt conveyor 3 to stop running. At the same time, the pallet on the lifting pallet AGV trolley 4 moves along the guide rail and extends to one side of the belt conveyor 3;

[0035] 3) When the limiting device 2 9 detects that the tray is in the iron receiving position, the control system 5 controls the tray to stop moving and controls the electromagnetic iron remover 2 to be powered off, that is, to be switched to a non-excitation state;

[0036] 4) When the electromagnetic iron remover 2 is in a non-excitation state, the ferromagnetic impurities 7 adsorbed thereon automatically detach and fall into the tray below. When the weighing sensor 1 monitors that the weight of the electromagnetic iron remover 2 reaches the set weight lower limit, a signal is sent to the lifting tray AGV trolley 4 through the control system 5, and the tray carrying the ferromagnetic impurities 7 returns to its original position along the guide rail;

[0037] 5) When the limit device 8 detects that the tray returns to its original position, a signal is sent to the control system 5, and the control system 5 controls the belt conveyor 3 and the electromagnetic iron remover 2 to restart;

[0038] 6) The lifting pallet AGV 4 carries the ferromagnetic impurities 7 back to the parking space and recycles the ferromagnetic impurities 7 .

[0039] In the intelligent material conveying and iron removal system described in the utility model, the functions and effects of each component are as follows:

[0040] The electromagnetic iron remover 2 is kept in an excited state when the belt conveyor 3 is operating normally to transport the material 6, so as to absorb the ferromagnetic impurities 7 mixed in the material 6; the electromagnetic iron remover 2 is kept in a non-excited state when the belt conveyor 3 is stopped to unload iron, at which time the ferromagnetic impurities 7 absorbed thereon automatically fall off due to their own weight; the electromagnetic iron remover 2 is controlled by the control system 5 to switch between the excited state and the non-excited state.

[0041] The weighing sensor 1 is connected to the electromagnetic iron remover 2 via a hanging device, and is used to continuously monitor the total weight of the electromagnetic iron remover 2 and the ferromagnetic impurities 7 absorbed thereon, and the measured weight data is transmitted to the control system 5.

[0042] The AGV chassis of the lifting pallet AGV trolley 4 can receive the control signal of the control system 5, and run back and forth between the parking space and the iron unloading space, and is used to receive the ferromagnetic impurities 7 unloaded by the electromagnetic iron remover 2, and transport the ferromagnetic impurities 7 to the recycling and processing area for centralized recycling and processing.

[0043] The lifting mechanism 42 in the lifting pallet AGV 4 is used to drive the pallet mechanism 43 to move up and down in the vertical direction to adjust the height of the pallet to adapt to different types of belt conveyors; the lifting mechanism 42 is preferably a hydraulic lifting mechanism, which has a stable action and a fast response speed. A scissor support is also provided between the base and the pallet mechanism 43 to play an auxiliary support role.

[0044] The tray mechanism 43 in the lifting tray AGV 4 is provided with a guide rail base, through which the horizontal movement of the tray is achieved; a pulley is embedded in the guide rail and powered by a busbar.

[0045] The limit device 1 8 and the limit device 2 9 are preferably proximity switches, which are located on both sides above the belt conveyor 3 and below the electromagnetic iron remover 2, and are used to monitor whether the pallet on the lifting pallet AGV trolley 4 reaches the initial position or the iron unloading position, so as to perform the iron unloading operation, and the detection signal is sent to the control system 5.
