Description

Technical Field

[0001] This invention belongs to the technical field of auxiliary devices for belt conveyor equipment, and specifically relates to an automatic belt unloading device. Background Technology

[0002] In the crushing area of ​​mineral processing plants, belt conveyors are widely used for transporting various materials. However, magnetic iron objects often get mixed in with the materials. If these iron objects are not removed in time, they will not only affect the quality of the materials, but may also cause serious damage to the belt and subsequent production equipment, increasing equipment maintenance costs and downtime, and reducing production efficiency.

[0003] Currently, common methods for removing magnetic impurities from belt conveyors mainly involve fixed electromagnetic chucks, manual removal, or other methods. While fixed electromagnetic chucks can achieve a certain degree of automatic iron removal, manual unloading is required after magnetic impurities are adsorbed, making full automation impossible. This also results in low efficiency and high labor intensity. Furthermore, if magnetic impurities accumulate to a certain level and are not detected and dealt with in time, it will affect the iron removal effect and may even cause equipment malfunction due to excessive impurities.

[0004] Therefore, developing a belt conveyor for removing iron impurities that can automatically detect, remove, and unload ironware has become an urgent technical problem to be solved. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0019] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0020] Example 1 Combination Figure 1 , Figure 2 As shown, the present invention provides an automatic belt derailment device, including a slide rail 1, a derailment trolley 2, a control mechanism, a receiving box 3, and a guardrail 4.

[0021] In some embodiments, the magnetic chuck is an electromagnetic chuck 5, which is disc-shaped and positioned directly above the belt conveyor 6. It is connected to the magnetic separator trolley 2 by a steel wire rope 7 and reciprocates along the slide rail 1 following the trolley 2. The slide rail 1, made of H-beam steel, is positioned directly above the belt conveyor 6. The magnetic separator trolley 2 is a trolley using an electric hoist, connected to the control mechanism via a power line through a drive motor 8. Cables are used to connect both sides of the slide rail 1. The magnetic separator trolley 2 slides on the slide rail 1, and the control mechanism controls the start and stop of the magnetic separator trolley 2 and the magnetic chuck.

[0022] Specifically, in some embodiments, the first end of the slide rail 1 is provided with a first travel limit switch 9, the first end of the slide rail 1 is located directly above the belt conveyor 6, the first travel limit switch 9 is connected to the control mechanism, and is used to transmit the start and stop signals of the iron separator traveling trolley 2 and the start signal of the magnetic suction component to the control mechanism; the second end of the slide rail 1 is provided with a second travel limit switch 10, the second travel limit switch 10 is connected to the control mechanism, and is used to transmit the start and stop signals of the iron separator traveling trolley 2 and the stop signal of the magnetic suction component to the control mechanism.

[0023] In some embodiments, the receiving box 3 is located on one side of the belt conveyor 6 and directly below the second end of the slide rail 1. The receiving box 3 is made of metal, and can be made of low-carbon steel plate or other wear-resistant metals, without specific limitations. Its top opening size is larger than the adsorption surface size of the electromagnetic chuck 5 to ensure that iron impurities can completely fall into the receiving box 3. The bottom of the receiving box 3 is equipped with a forklift fork slot 11 for easy insertion and handling by forklifts. According to the site requirements, this application manufactures the receiving box 3 with a length, width and height of one meter each. Two sets of 140mm channel steel are welded to the bottom plate of the receiving box 3, with a spacing of 500mm between the channel steels. The forklift forks are inserted into both sides of the two channel steels to ensure the stability of the receiving box 3. The receiving box 3 adopts a bottom discharge method for easy cleaning and storage of ironware.

[0024] In some embodiments, combined with Figure 2 As shown, guardrails 4 are installed along the length of slide rail 1 on both sides of slide rail 1 and around the receiving box 3, isolating the travel route of the iron separator trolley 2. The guardrails 4 are no less than 1.2 meters high, made of high-strength steel, and the spacing between the guardrails is no more than 15 centimeters, forming a closed protective area to prevent personnel from accidentally entering the working area of ​​the automatic iron unloading device and causing safety hazards. The guardrails 4 adopt a one-way opening method, with one end fixed by a door hinge 12 and the other end equipped with a door lock that is always locked. The safety sensor 13 mainly consists of limit switches, installed inside the guardrails 4, and electrically connected to the control mechanism. The guardrails 4 are always locked to prevent personnel or objects from entering the vicinity of the iron unloader and causing safety hazards. When personnel enter the protective area and open the guardrail, a signal is immediately transmitted to the control mechanism, which then stops the iron separator trolley 2.

[0025] In some embodiments, the control mechanism consists of a PLC system and an electrical control box. The start and stop of the iron removal trolley 2 and the electromagnetic chuck 5 can be directly controlled by the control buttons on the electrical control box, or they can be remotely controlled by the PLC.

[0026] When using the automatic belt unloading device provided in the embodiments of this application for automated control, the main steps are as follows: Step S1: Start the device. The iron removal trolley 2 is in the starting position, that is, the first end of the slide rail 1. At this time, the belt conveyor 6 starts to transport materials. The belt running sensor starts to record the belt running time. When the belt running signal is detected, it is transmitted to the PLC system. Through the interlocking electrical control box, the PLC system sends a start command to the electrical control box. The electrical control box immediately controls the electromagnetic chuck 5 to be energized and start working to adsorb the iron on the belt.

[0027] Step S2: Adjust the unloading time according to the amount of iron adsorbed. When the belt runs for the preset time (e.g., one hour), the adsorption stage is completed. The PLC issues a start command, and the electrical control box controls the drive motor 8 to work, driving the iron remover trolley 2 to move the electromagnetic chuck 5 assembly to the second end of the slide rail 1.

[0028] Step S3: When the iron removal trolley 2 moves to the iron unloading reference point and triggers the second stroke limit switch, the second stroke limit switch transmits a signal to the PLC system. The PLC system issues a stop command, and the electrical control box controls the drive mechanism to stop working, so that the electromagnetic chuck 5 stops precisely at the iron unloading position. At the same time, the electrical control box controls the electromagnetic chuck 5 to automatically cut off the power, and the iron adsorbed is directly discharged into the receiving box 3 below under the action of gravity.

[0029] Step S4: After unloading is completed, the PLC issues a return command. The electrical control box controls the drive motor 8 to drive the iron separator trolley 2 in reverse along the slide rail 1 to the top of the belt conveyor. When the electromagnetic chuck 5 returns to its initial position and triggers the first travel limit switch, the first travel limit switch transmits a signal to the PLC system. The PLC system issues a stop command, the electrical control box controls the drive mechanism to stop working, the iron separator trolley 2 stops, and at the same time immediately controls the electromagnetic chuck 5 to be powered on and start working to begin the next iron removal operation.

[0030] Step S5: Periodically use a forklift to insert into the forklift fork slot at the bottom of the receiving box 3 to transport the receiving box 3 to a designated location for recycling of iron impurities.

[0031] Combination Figure 3 As shown in the embodiment of this application, the control principle of the electrical control box in the automatic belt de-iron removal device is as follows: The electrical control box mainly consists of a power supply box, circuit breaker, contactor, intermediate relay, time relay, button, indicator light, universal changeover switch, etc. The power supply circuit of the electromagnetic chuck 5 (via contactor KM1) and the de-iron removal start are interlocked by the belt running signal and the contacts of the time relay. After being triggered by the time relay, the intermediate relay controls the forward contactor KM2 of the drive motor 8 to engage, causing the de-iron removal trolley 2 to move towards the de-iron removal position.

[0032] First travel limit switch: Triggered when the iron remover trolley returns to the initial position, its normally open contact closes to stop the return motor (KM2).

[0033] Moving towards the unloading position (forward rotation): KT1 reaches the set time → KT1 delay-closed normally open contact closes → intermediate relay KA2 coil is energized. KA2 normally open contact closes → contactor KM1 coil is energized → drive motor M1 rotates forward, and the iron separator trolley moves towards the unloading position. KA2 normally closed contact opens → ensuring KM2 cannot be energized (interlock).

[0034] Iron removal stop and iron removal: The iron remover trolley reaches the iron removal position → the second travel limit switch is pressed (normally open contact closes) → the intermediate relay KA3 coil is energized → the normally closed contact of KA3 opens → the contactor KM1 coil is de-energized → the drive motor stops, and the iron remover trolley stops. The normally closed contact of KA3 opens → the contactor KM3 coil is de-energized → the electromagnetic chuck EM is de-energized and demagnetized, and the iron falls. The normally open contact of KA3 closes → the time relay KT2 coil is energized (delay after iron removal begins).

[0035] Return to initial position (reverse): KT2 reaches short-time setting → KT2 delay-closed normally open contact closes → contactor KM2 coil is energized → KM2 main contact closes → drive motor M1 reverses, and the iron remover trolley returns to the initial position.

[0036] The normally closed auxiliary contact of KM2 is open (interlocked with KM1).

[0039] 3. In this embodiment of the application, through the structural design of the protective mechanism, the protective railing 4 forms a closed protective area and is always locked.
