Description

Technical Field

[0001] The utility model belongs to the technical field of raw ore transportation, and specifically relates to an automatic iron removal and unloading device in the transportation process of crushed raw ore. Background Art

[0002] In the flow of crushed ore unloaded by the conveyor belt, there are inevitably various debris, especially some iron debris. If the iron debris is transported to the subsequent process together with the crushed ore, on the one hand, it will affect the quality of the crushed ore, making the subsequent processing of the crushed ore unable to proceed normally, and on the other hand, the iron debris entering the subsequent process may cause damage to the equipment of the subsequent process and affect normal production operations. Therefore, in the process of conveying the crushed ore, the iron debris mixed in it must be removed.

[0003] At present, electromagnetic iron removers are usually used to adsorb and remove iron debris in crushed ore. After the iron debris is adsorbed on the electromagnetic iron remover, it is necessary to manually remove the iron debris adsorbed on the electromagnetic iron remover. Since the electromagnetic iron remover is set above the conveyor belt, when unloading the iron debris, the iron debris may fall on the conveyor belt, and the operator has to pick it up and bag it again. The entire iron debris removal process is time-consuming and consumes a lot of human resources, which seriously affects production efficiency. The patent with patent number 202011018495.2 discloses a suspended self-unloading permanent magnetic iron remover, in which the excitation system is arranged inside the iron unloading belt and there is a lifting ring for hanging and lifting. Its working process is to adsorb iron debris to the iron unloading belt through the permanent magnetic unit, and then the iron unloading belt transports the iron debris to the discharge port. The iron debris is out of the magnetic range and falls into the discharge port to realize the self-unloading function. However, in the process of realizing the self-unloading function, the permanent magnetic unit adsorbs the iron debris to the iron unloading belt. If the adsorption force is too large, it may hinder the belt transportation, and the range of each iron debris out of the magnetic adsorption is also different. There are too many unstable factors in realizing the automatic iron unloading function by escaping the magnetic range.

[0004] Therefore, it is necessary to provide an automatic iron removal and unloading device during the transportation process of crushed ore, which can realize the automatic unloading of iron debris already adsorbed on the electromagnetic iron remover and the automatic re-adsorption effect of the electromagnetic iron remover after the iron debris is unloaded through different implementation methods, thereby reducing the time and human resource consumption of the iron debris unloading process and improving production efficiency.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technicians.

[0025] like Figure 1-4As shown, the automatic iron removal and unloading device in the crushed ore transportation process includes a control system 1, a mobile system 2, a sling 3, an electromagnetic iron remover 4, and an iron unloading container 5. The control system 1 includes a first displacement sensor 101, a second displacement sensor 102, a weighing sensor 103, and a PLC controller 104. The first displacement sensor 101, the second displacement sensor 102, and the weighing sensor 103 are all fixedly arranged on the mobile system 2. The mobile system 2 is fixedly arranged above the conveying belt 6 and the iron unloading container 5. One end of the sling 3 is fixedly connected to the measuring end of the weighing sensor 103, and the other end is fixedly connected to the electromagnetic iron remover 4. The iron unloading container 5 is arranged on one side of the conveying belt 6 and is located at a corresponding position below the electromagnetic iron remover 4. The PLC controller 104 has multiple input ends and output ends, and the output end of the first displacement sensor 101 and the output end of the second displacement sensor 102 are fixedly connected. , the output end of the weighing sensor 103 is electrically connected to three different input ends of the PLC controller 104 respectively, the input end of the mobile system 2 and the input end of the electromagnetic iron remover 4 are electrically connected to two different output ends of the PLC controller 104 respectively; the mobile system 2 includes a track 201 and a power car 202, the track 201 is perpendicular to the material conveying direction of the conveying belt 6 and is arranged above the conveying belt 6 and the iron unloading container 5, the first displacement sensor 101 and the second displacement sensor 102 are fixedly arranged on the track 201, the power car 202 is slidably connected to the track 201 and moves on the track 201 between the first displacement sensor 101 and the second displacement sensor 102, the input end of the power car 202 is electrically connected to an output end of the PLC controller 104, and the weighing sensor 103 is fixedly arranged at the bottom of the power car 202; the track 201 is an I-beam. First, the preset values ​​of each sensor are set and input into the corresponding sensor, and then the preset program is edited and input into the PLC controller 104, so that the control system 1 can be controlled according to the preset parameters. When it is necessary to adsorb and remove iron debris, the PLC control 104 is manually controlled. The PLC control 104 controls the power car 202 to move along the track 201 to the position of the conveyor belt 6. The power car 202 drives the electromagnetic iron remover 4 to move to the position of the conveyor belt 6 through the driving action of the sling 3. Since the power car 202 moves synchronously with the electromagnetic iron remover 4, when the electromagnetic iron remover 4 moves to a suitable position, the power car 202 also reaches the preset position. The second displacement sensor 102 measures the preset value of the power car 202 reaching the preset position, and transmits the signal to the PLC controller 104. The PLC controller 104 receives the signal sent by the second displacement sensor 102, that is, automatically controls the power car 202 to stop and controls the electromagnetic iron remover 4 to start, and starts to adsorb iron debris.As the electromagnetic iron remover 4 absorbs more and more iron debris, its weight also increases. When the weight of the electromagnetic iron remover 4 reaches a preset value after absorbing the iron debris, the weighing sensor 103 measures that the weight of the electromagnetic iron remover 4 reaches a preset value after absorbing the iron debris, and then it transmits a signal to the PLC controller 104. The PLC controller 104 controls the power car 202 to move along the track 201 to the position of the iron unloading container 5. The power car 202 drives the electromagnetic iron remover 4 to move together. When the electromagnetic iron remover 4 moves to the top of the iron unloading container 5, the first displacement sensor 101 measures that the displacement of the power car 202 reaches the preset value, that is, it transmits a signal to the PLC controller 104. After receiving the signal, the PLC controller 104 controls the power car 202 stops and controls the electromagnetic iron remover 4 to be closed, and the iron debris loses its magnetic adsorption effect and falls into the iron unloading container 5 for unified treatment. When the residence time of the electromagnetic iron remover 4 reaches the preset time, the PLC controller 104 controls the power car 202 to move along the track 201 to the position of the conveyor belt 6, and repeats the above-mentioned iron debris adsorption and unloading process. During the whole process, it is only necessary to manually set the preset values ​​of all sensors and input the corresponding program into the PLC controller 104, and then manually start the PLC controller 104 and control the power car 202 to move when starting the iron debris adsorption. The rest of the operations can be completed automatically, which reduces the time of the iron debris unloading process and the consumption of human resources, and improves production efficiency.

[0026] The control system 1 further includes a DCS control system 105, an output end of the DCS control system 105 is electrically connected to an input end of the PLC controller 104, and an input end of the DCS control system 105 is electrically connected to an output end of the PLC controller 104. The PLC controller 104 is set at the crushed ore transportation site, and the operator can control it through the PLC controller 104 on site and connect to the DCS control system 105 at the same time, and can also remotely operate the on-site iron debris removal through the DCS control system 105, so that the operator can intervene in manual operation at different locations.

[0027] The lifting device 3 is a chain lifting device, which is composed of at least three chains, and the connection points between the lifting device 3 and the electromagnetic iron remover 4 are evenly distributed along the circumferential direction of the electromagnetic iron remover 4. The lifting device 3 makes the lifting and driving movement of the electromagnetic iron remover 4 more stable and firm.

[0028] The distance between the electromagnetic iron remover 4 and the conveyor belt 6 is 300 mm, which is most conducive to the electromagnetic iron remover 4 to adsorb iron debris.

[0029] The working process of the utility model is as follows: before removing iron debris, firstly, the circuits of various sensors and controllers are connected, and then the preset values ​​of various sensors are set and the control programs that meet the requirements are input into various controllers. After completion, the power car is controlled to move along the track toward the transport belt through the PLC controller or the DCS control system. Subsequently, the system can be automatically controlled, and the operator only needs to observe the operation of the system and timely intervene in manual operation when necessary.

[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
