Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to a magnetic sealing structure and a belt conveyor. Background Art

[0002] When using tape to transport materials containing fine particles, when the speed of the conveying tape is relatively fast, or at the receiving and unloading points of the tape conveyor, the fine particles in the transported materials will flow with the air to generate dust. Generally, water spraying or sealing cover is used to suppress dust. Water has a bad effect on some transported materials, so it is not suitable to suppress dust by spraying water. Most of the sealing cover dust suppression methods use contact parts to contact the surface of the conveying tape to achieve sealing. The seals of the contact seal can be steel plates, wooden boards, rubber plates, polyurethane plates, canvas, hanging ropes, etc. These seals are in contact with the running tape surface and will wear the tape surface. Long-term use will cause the tape to wear and shorten the service life of the tape; at the same time, it will also wear the seals, and it is necessary to adjust the gap between the seal and the tape surface in time to maintain the sealing performance; whether it is the wear of the tape surface or the wear of the seal, it will increase the gap between the seal and the tape surface, reduce the sealing performance, and even generate dust and pollute the working environment.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0039] The utility model provides a magnetic sealing structure and a belt conveyor.

[0040] In the embodiment of the present utility model, Figures 1 to 4 As shown, a magnetic sealing structure 10 is provided, which includes a magnetic sealing component 100, a fixing component 200 and an adjusting component 300. The magnetic sealing component 100 is arranged above the conveying tape 20, and the magnetic sealing component 100 is located on both sides of the conveying tape 20 along the conveying direction. The magnetic sealing component 100 has a magnetic surface 111 opposite to and spaced from the material-carrying surface 21 of the conveying tape 20, and the magnetic surface 111 is used to absorb magnetite particles to form a magnetite sealing layer at the gap between the material-carrying surface 21 and the magnetic surface 111; the fixing component 200 is connected to the end of the magnetic sealing component 100 away from the conveying tape 20; the adjusting component 300 is connected to the fixing component 200, and the adjusting component 300 is used to adjust the distance between the magnetic surface 111 and the material-carrying surface 21.

[0041] The magnetic sealing assembly 100 is disposed above the transport tape 20 to ensure that the magnetic surface 111 of the magnetic sealing assembly 100 can partially cover the material carrying surface 21 of the transport tape 20 , thereby providing necessary space for forming a sealing layer.

[0042] The magnetic sealing components 100 are located on both sides of the transport tape 20 along the transport direction, and can fully cover both sides of the transport tape 20. After forming a magnetite sealing layer, it can effectively prevent material splashing and dust escape, while reducing material loss.

[0043] The magnetic sealing component 100 has a magnetic surface 111 opposite to and spaced from the carrying surface 21 of the transport tape 20. The magnetic surface 111 is the key to forming a sealing layer. It maintains a certain distance from the carrying surface 21 so that magnetite particles can be adsorbed and accumulated under the action of the magnetic field to form a stable and effective sealing layer.

[0044] The fixing component 200 is connected to the end of the magnetic sealing component 100 away from the transport tape 20. The fixing component 200 serves to suspend, fix and stabilize the magnetic sealing component 100 to ensure that it will not shift or fall off due to vibration or impact during the tape transportation process.

[0045] The fixing assembly 200 is connected to the adjusting assembly 300, so that the adjusting assembly 300 can accurately control the position and posture of the magnetic sealing assembly 100. The adjusting assembly 300 is used to adjust the gap between the magnetic surface 111 and the material loading surface 21. It can be flexibly adjusted according to different working conditions and material characteristics to ensure the best sealing effect.

[0046] Through the synergistic effect of the above technical features, the magnetic sealing structure 10 can form a stable and effective magnetite sealing layer on both sides of the conveying tape 20 along the conveying direction. It can not only effectively prevent material splashing and dust escape, reduce material loss and reduce environmental pollution, but also reduce the wear between the conveying tape 20 and the sealing component, and extend the service life of the conveying tape and the seal. At the same time, the addition of the adjustment component 300 makes the entire sealing structure more flexible and can be adjusted according to different working conditions to ensure that the sealing effect is always maintained in the best state.

[0047] The present application arranges a magnetic sealing component 100 on both sides of the conveying tape 20 along the conveying direction, wherein the magnetic sealing component 100 has a magnetic surface 111 opposite to and spaced from the carrying surface 21 of the conveying tape 20, and utilizes the magnetite particles to be adsorbed on the magnetic surface 111 under the action of the magnetic field force, and the magnetic surface 111 is adsorbed with fine-grained magnetite particles to form a magnetite sealing layer; the magnetite sealing layer and the carrying surface 21 of the conveying tape 20 are in contact to form an effective seal, and the friction generated between the magnetite sealing layer and the carrying surface 21 is dynamic friction (such as rolling friction), which is much smaller than the sliding friction between planes. Therefore, it can effectively prevent the splashing of transported materials and the escape of dust, and at the same time, it can effectively reduce the wear of the carrying surface 21 of the conveying tape 20 and the magnetic sealing component 100, stably maintain the sealing of the space of the belt conveyor cover, and can extend the service life of the conveying tape 20 and the magnetic sealing component 100.

[0048] According to a magnetic sealing structure 10 provided by the utility model, the particle size of magnetite particles in the magnetite sealing layer is less than or equal to 10 mm.

[0049] It is understandable that when the conveying material of the belt conveyor is magnetite, the magnetite particles in the magnetite are adsorbed on the magnetic surface under the action of the magnetic field force. After the belt conveyor has been in production and operation for several hours, the magnetic surface 111 of the magnetic sealing component 100 is adsorbed with fine-grained magnetite particles to form a magnetite sealing layer with uniform thickness; the sealing layer adsorbed with fine-grained magnetite rubs against the surface of the conveying belt 20, but the friction is very small, and the wear of the surface of the belt transporting the ore is also very small, thereby extending the service life of the conveying belt; if the belt conveyor does not convey magnetite ore, but the magnetite particles have no pollution or destructive effect or other effects on the conveying material, magnetite particles can also be added to the magnetic surface 111 of the magnetic sealing component 100 in advance, so that the magnetic surface 111 is adsorbed with fine-grained magnetite particles to form a magnetite sealing layer with uniform thickness, and the particle size of the magnetite particles in the magnetite sealing layer is less than or equal to 10 mm. Smaller particle size helps to arrange particles more closely, reduce pores, and thus improve sealing performance. At the same time, the moderate particle size makes the magnetite particles have better fluidity during the filling process, and can be more evenly distributed in the sealing area, effectively filling various tiny gaps. In addition, smaller particles are not easy to move or fall off when subjected to external forces, which enhances the long-term stability of the sealing structure.

[0050] Preferably, the particle size of the magnetite particles in the magnetite sealing layer is 0.1 mm-1 mm.

[0051] According to a magnetic sealing structure 10 provided by the utility model, the distance between the magnetic surface 111 and the material-carrying surface 21 is greater than or equal to 1 mm and less than or equal to 20 mm.

[0052] It is understandable that the setting of the distance between the magnetic surface 111 and the material-carrying surface 21 directly affects the sealing effect. Too small a distance may increase the friction between the sealing surface and the material-carrying surface 21, increase wear and energy consumption; while too large a distance may reduce the sealing performance, causing the transported material to splash and dust to escape. Within the range of 1 mm to 20 mm, the sealing effect and operating stability can be better balanced to ensure that the sealing structure can maintain good sealing performance under different working conditions.

[0053] Reference Figure 7 According to a magnetic sealing structure 10 provided by the utility model, the spacing between the magnetic sealing components 100 located on both sides of the extending direction of the transport tape 20 is less than or equal to the width of the transport tape 20.

[0054] It is understood that the entire width of the transport tape 20 is effectively blocked by the magnetic sealing assembly 100 during operation, thereby preventing the transported material from splashing and dust from escaping from both sides of the tape. The tightly fitting magnetic sealing assembly 100 reduces potential leakage points caused by unsealed areas within the width of the tape, thereby improving the overall sealing effect.

[0055] Reference Figures 1 to 3 According to a magnetic sealing structure 10 provided by the utility model, the magnetic sealing assembly 100 includes an outer shell 110 and a magnetic system 120, the outer shell 110 is formed with a accommodating cavity 112, a magnetic surface 111 is formed on the bottom end surface of the outer shell 110, the magnetic system 120 is arranged in the accommodating cavity 112, and the magnetic system 120 includes N magnetic blocks 121 stacked in a direction away from the magnetic surface 111, wherein N is greater than or equal to 1.

[0056] It is understandable that, in the present embodiment, the exterior of the magnetic sealing assembly 100 is a U-shaped outer shell 110 made of a non-magnetic material. An accommodating cavity 112 is designed inside the outer shell 110 for placing the magnetic system 120. The magnetic system 120 is composed of N magnetic blocks 121 stacked in a direction away from the magnetic surface 111, where N is greater than or equal to 1. This stacked structure enables the magnetic system 120 to generate a stronger magnetic field, thereby improving the sealing effect. The magnetic blocks 121, through their magnetic attraction, tightly adsorb the magnetite particles or other magnetic materials in the magnetite transported by the conveying tape 20 on the magnetic surface 111, forming an effective seal. The stacked arrangement of the magnetic blocks 121 can also adjust the strength and distribution of the magnetic field according to actual needs to adapt to different sealing requirements. The upper part is made of carbon steel plate as the magnetic conductive bottom plate and the load-bearing bottom plate, and a magnetic plane is formed at the lower part of the magnetic sealing component 100; the magnetic block 121 is preferably a strontium ferrite magnetic block. If it is desired to obtain a stronger magnetic surface 111 or the thickness of the magnetic component is required to be thinner, the magnetic block 121 can be a neodymium iron boron magnetic block, and no special limitation is made here.

[0057] Reference Figure 1 , Figure 4 , Figure 6 and Figure 7 According to a magnetic sealing structure 10 provided by the utility model, the fixing assembly 200 includes a fixing plate 210 and a fixing frame 220 arranged on the fixing plate 210, the magnetic sealing assembly 100 is connected to the fixing frame 220, and the fixing frame 220 is connected to the hood top plate of the belt conveyor through the fixing plate 210.

[0058] It is understandable that the fixing plate 210 is the basic part of the fixing assembly 200, and is used to install and support the fixing frame 220 and the magnetic sealing assembly 100. The fixing plate 210 is connected to the hood top plate or the supporting frame of the belt conveyor through the adjustment assembly to ensure the stability and reliability of the entire magnetic sealing structure 10. The fixing frame 220 is used to connect the magnetic sealing assembly 100 and the fixing plate 210. The fixing frame 220 can be designed according to the shape and size of the magnetic sealing assembly 100 to ensure that the magnetic sealing assembly 100 can be accurately and firmly installed on the fixing plate 210. The fixing frame 220 is connected to the fixing plate 210 by bolts, slots or other connection methods, and the magnetic sealing assembly 100 can be accurately installed and positioned by adjusting the position and angle of the fixing plate 210.

[0059] Reference Figure 3 According to a magnetic sealing structure 10 provided by the present invention, the magnetic sealing assembly 100 further includes a first connecting member 130 , and the magnetic sealing assembly 100 is connected to the fixing frame 220 via the first connecting member 130 .

[0060] It is understood that the first connector 130 ensures that the magnetic seal assembly 100 can be stably and accurately mounted on the fixing frame 220. The first connector 130 can be a bolt, a buckle, a pin, a flange or other special connectors, depending on the shape, weight, installation requirements and working environment of the magnetic seal assembly 100. The first connector 130 connects the magnetic seal assembly 100 to the fixing frame 220, which can be bolted, clamped, pinned or welded. During the connection process, it is necessary to ensure that the connection is tight and not loose, so as to withstand the vibration and impact force when the belt conveyor is running.

[0061] Reference Figure 1 or Figure 6 According to a magnetic sealing structure 10 provided by the present invention, the adjusting component 300 is disposed at one end of the fixing plate 210 away from the magnetic seal, and the adjusting component 300 is used to adjust the distance between the magnetic surface 111 and the loading surface 21 .

[0062] It is understood that the setting of the adjustment component 300 allows the user to adjust the distance between the magnetic surface 111 and the upper surface of the belt conveyor as needed to ensure that the magnetic sealing structure 10 can effectively seal. The adjustment of the distance can ensure that the magnetic sealing structure 10 can achieve the best effect when processing different materials.

[0063] Reference Figure 5 , Figure 8 and Fig. 9According to a magnetic sealing structure 10 provided by the utility model, the adjustment component 300 includes an adjustment seat 310, an adjustment rod 320 and a second connecting member 330. Part of the adjustment rod 320 is movably arranged in the adjustment seat 310. The adjustment seat 310 is provided with an adjustment hole 311 extending along the height. The second connecting member 330 is passed through the adjustment hole 311. The second connecting member 330 is used to connect and fix the fixing plate 210 to the lower end of the adjustment rod 320, and the upper end of the adjustment rod 320 is movably connected to the adjustment seat 310.

[0064] It is understandable that the adjustment seat 310 is the basic supporting component of the entire adjustment assembly 300. The adjustment seat 310 not only provides a platform for installing and fixing other components, but also allows the adjustment rod 320 to move up and down through its internal structure design, making the adjustment of the sealing structure more flexible and convenient.

[0065] The adjusting rod 320 is a component connecting the adjusting seat 310 and the fixing plate 210, and is movably arranged in the adjusting seat 310. The adjusting rod 320 can move within a certain range, thereby driving the fixing plate 210 connected thereto to make corresponding position adjustments. The adjusting seat 310 is provided with an adjusting hole 311 extending along the height, and the adjusting hole 311 is a channel for the adjusting rod 320 and the second connecting member 330 to realize the lifting and fixing. The second connecting member 330 is penetrated in the adjusting hole 311, and its main function is to connect and fix the fixing plate 210 to the lower end of the adjusting rod 320. The upper end of the adjusting rod 320 is movably connected to the adjusting seat 310, allowing the adjusting rod 320 to move or rotate relative to the adjusting seat 310 when subjected to external force. In this way, the position of the fixing plate 210 can be flexibly adjusted and firmly fixed through the coordination and cooperation of the adjustment seat 310 , the adjustment rod 320 , the adjustment hole 311 , and the second connecting member 330 , thereby achieving adjustment of the distance between the magnetic surface 111 and the loading surface 21 .
