Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical environmental protection mechanical equipment, in particular to a belt conveyor for a rotary hearth furnace with a fence protection system. Background Art

[0002] Belt conveyor is the abbreviation of belt conveyor. It is a continuous conveying machine with fixed and mobile types, simple structure, high efficiency, and flexible conveyor belt as material carrying and traction component. An endless conveyor belt surrounds the driving drum and the redirecting drum. The upper and lower branches between the two drums are supported by several rollers. The material is placed on the upper branch. The friction between the driving drum and the belt is used to drag the conveyor belt and the material to run. It is suitable for conveying bulk materials and finished items in horizontal and inclined directions, and can also be used in assembly lines for certain process operations.

[0003] The normal operation of the rotary hearth furnace process includes processes such as mixing, pelletizing, and discharging, in which belt conveyors are required to transport materials in many stages. There are many safety hazards in the operation of belt conveyors, mainly including fires caused by frictional heat generated by roller jamming and injuries caused by people accidentally entering rotating machinery. In order to prevent on-site workers from accidentally entering the running belt conveyor equipment and getting injured during work, safety devices such as pull ropes, fences, and protective covers are designed and installed on each belt conveyor.

[0004] However, such protective measures as fences and protective covers can only serve as warnings or prevent people from entering the running conveyor belt, and the pull-rope switch can only protect workers from accidentally starting the equipment when the machine is shut down for maintenance, thereby preventing casualties. When a safety accident occurs on site, it is still necessary to press the emergency stop button of the equipment on site, or notify the central control to stop the equipment, and the accompanying personnel cannot take effective measures in the first time to prevent the further expansion of the injury. Therefore, this application proposes a conveyor belt for a rotary hearth furnace with a fence protection system. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a belt conveyor for a rotary hearth furnace with a fence protection system. When the protective body of the belt conveyor leaves its original position to a large extent, the electronic fence pulse host installed on the electronic fence can send out an alarm signal and control the switch of the belt conveyor to cut off the power and stop urgently, thereby preventing further injury to personnel and the occurrence of production accidents, and reducing the probability of safety accidents.

[0006] The rotary hearth furnace belt conveyor with a fence protection system in this scheme includes a belt conveyor main body placed on the ground, a protective body is arranged on one side or both sides of the belt conveyor main body in the width direction, an electronic fence is also arranged on the side of the protective body away from the belt conveyor main body, a gap is arranged between the electronic fence and the protective body, and the height of the electronic fence is adapted to the height of the protective body, wherein an electronic fence pulse host is installed on the electronic fence, and a switch for controlling its start and stop is installed on the belt conveyor main body and is electrically connected to the electronic fence pulse host.

[0007] The technical solution further defined in the utility model is:

[0008] Furthermore, the protective body includes a protective fence arranged on one side or both sides of the belt conveyor body, and there is a gap between the protective fence and the belt conveyor body.

[0009] Furthermore, the protective body includes a protective cover arranged outside the belt conveyor body, and a gap is provided between the protective cover and the belt conveyor body.

[0010] Furthermore, the top of the protective cover is arched.

[0011] Furthermore, the protective cover is composed of a plurality of protective sub-cover bodies assembled in the transmission direction of the belt conveyor body.

[0012] Furthermore, the protective sub-covers are connected by bolts.

[0013] Furthermore, the belt conveyor body includes a fixed belt conveyor or a mobile belt conveyor.

[0014] The beneficial effect of the utility model is that when the utility model is applied in the rotary hearth furnace process, when the protective body of the belt conveyor leaves its original position to a large extent, the electronic fence pulse host installed on the electronic fence can send out an alarm signal and control the switch of the belt conveyor to cut off power and stop urgently, thereby preventing further injury to personnel and the occurrence of production accidents, reducing the probability of safety accidents and improving production safety.

[0020] like Figure 1 and Figure 2 As shown, there are respectively a three-dimensional structural diagram and a front structural diagram of a belt conveyor for a rotary hearth furnace provided in an embodiment of the present application, comprising a belt conveyor body 10 placed on the ground. The belt conveyor body 10 can be a fixed belt conveyor or a mobile belt conveyor. Protective fences 20 are vertically installed on the ground on both sides of the width direction of the belt conveyor body 10, and electronic fences 30 are vertically installed outside the two protective fences 20. There is a certain gap between the protective fences 20 and the belt conveyor body 10, and there is also a certain gap between the protective fences 20 and the electronic fences 30. The height of the electronic fence 30 is adapted to the height of the protective fence 20, and an electronic fence pulse host 31 is installed on one of the electronic fences 30. A switch 11 for controlling its start and stop is installed on the belt conveyor body 10 and is electrically connected to the electronic fence pulse host 31.

[0021] In some specific embodiments, the electronic fence pulse host 31 can integrate functions such as alarm and intelligent display. When the protective cover or fence of the on-site belt conveyor is far away from its original position, for example, a worker accidentally falls and hits the protective cover and fence, or subjectively removes or moves the protective cover of the running belt conveyor privately, the electronic fence 30 can automatically send out an alarm signal, and cut off the power to stop the belt and related equipment at this stage, which can not only prevent the injured employee from being further injured, but also ensure the chain start and stop of the overall process equipment without production accidents. At the same time, the interface fed back by the electronic fence 30 to the central control monitoring can clearly observe whether the security facilities such as the protective cover are in the normal position. When looseness or deviation occurs, it can promptly notify professionals to make adjustments to reduce the probability of safety accidents.

[0022] It should be noted that the protective body in the present application refers to a protective device used in the past for the belt conveyor of the rotary hearth furnace, which can be a device such as a protective cover or a fence. In the above embodiment, the protective body is composed of a protective fence 20. In another embodiment, as shown in FIG. Figure 3 As shown, the protective body is specifically a protective cover 40 with an arched top, and there is a certain gap between the protective cover 40 and the belt conveyor body 10.

[0023] like Figure 4As shown, the aforementioned protective cover 40 can be an integrally formed cover body, or it can be composed of multiple protective sub-cover bodies 41 assembled in the transmission direction of the belt conveyor body 10. The assembly method can be mortise and tenon, welding or bolts. In this embodiment, bolt connection is used to achieve relative fixation between the protective sub-cover bodies 41.

[0024] In addition to the above embodiments, the present invention may also have other implementation modes; any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
