Description

Technical Field

[0001] This utility model relates to the field of fluidized bed furnace feeding platforms, specifically to a closed feeding belt platform for a fluidized bed furnace. Background Technology

[0002] As a crucial industrial roasting equipment, the fluidized bed furnace requires a continuous and stable conveyor belt to transport raw material pyrite into the furnace for roasting. Currently, the commonly used conveyor belt installation method has significant drawbacks: the conveyor belt is typically erected on an open, high-altitude loading platform, which easily generates large amounts of dust during material transport. This dust not only wastes raw materials but also severely pollutes the surrounding production environment and affects the health of operators. Especially when transporting dust-generating raw materials such as pyrite, open-air conveying methods can lead to severely excessive dust concentrations in the plant area. Furthermore, existing open conveyor platforms also face problems such as rainwater erosion and material moisture absorption, seriously affecting the stable operation of the conveying system. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a closed platform for the feeding belt of a fluidized bed furnace.

[0004] This utility model is achieved through the following technical solution:

[0005] This application provides a closed platform for a fluidized bed furnace feeding belt, including a feeding conveyor belt installed on the feeding platform of the fluidized bed furnace. A closed cover is installed on the upper part of the feeding platform. The closed cover includes several sets of support vertical rods arranged on the edge of the feeding platform. Multiple frame-shaped short sections assembled from bottom to top are snapped into the inner side of the several sets of support vertical rods. The top of the uppermost frame-shaped short section is connected to a cover plate.

[0006] Furthermore, this application also proposes that each set of support vertical rods includes two support vertical rods, one inner and one outer, with a snap-fit ​​gap between the two support vertical rods for a snap-fit ​​frame-type short section.

[0007] Furthermore, this application also proposes that an H-shaped connecting strip is provided between adjacent frame-shaped short sections, and the H-shaped connecting strip is sealed to the frame-shaped short sections through the slots at the upper and lower ends of the connecting strip.

[0008] Furthermore, this application also proposes that an outer frame is installed on the outer side of the frame-shaped short section at the lower part of the cover plate, and the outer frame and the frame-shaped short section have a slot for engaging the outer support vertical rod.

[0009] Furthermore, this application also proposes that a connection hole for connecting the fluidized bed furnace feed box is opened on one side of the enclosed cover, and the connection hole is directly opposite the discharge port of the feeding conveyor belt.

[0010] Compared with existing technologies, the advantages of this utility model are: by setting up a closed cover consisting of supporting vertical rods, frame-shaped short sections and cover plates on the feeding platform, a complete sealed space is formed, which effectively prevents dust diffusion during material transportation and avoids rainwater erosion, thus achieving significant environmental protection and raw material saving effects.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0017] like Figure 1-4 As shown, this application proposes a closed platform for a fluidized bed furnace feeding belt, including a feeding conveyor belt installed on the feeding platform of the fluidized bed furnace, a closed cover installed on the upper part of the feeding platform, the closed cover including several sets of support vertical rods set on the edge of the feeding platform, and several frame-shaped short sections spliced ​​and assembled from bottom to top on the inner side of the several sets of support vertical rods, and a cover plate connected to the top of the uppermost frame-shaped short section.

[0018] The feeding conveyor belt is used to transport the raw material, pyrite, into the fluidized bed furnace. The feeding platform provides the installation foundation for the conveyor belt and is typically a steel frame structure. The enclosed enclosure is fixed to the edge of the feeding platform by supporting vertical rods, which can be made of angle steel or square steel tubing. The number of supporting vertical rods in each set can be adjusted according to the platform dimensions. The frame-type short section has a rectangular frame structure. The cover plate can be made of steel plate and fixed to the top frame-type short section with bolts.

[0019] This technical solution effectively prevents dust diffusion during the conveying process by installing a closed enclosure on the loading platform. The combined structure of the supporting vertical rods and frame-type short sections allows for easy adjustment of the enclosure height according to actual needs and provides good structural stability. Furthermore, assembly and disassembly are more convenient and efficient, requiring only a crane for assembly, significantly reducing high-altitude welding work and improving safety. The modular design of the frame-type short sections makes installation and maintenance more convenient while reducing manufacturing costs. Therefore, this closed platform significantly improves the working environment while ensuring conveying functionality, solving the dust pollution problem caused by existing open-air conveying systems.

[0020] Furthermore, this application also proposes that each set of support vertical rods includes two support vertical rods, one inner and one outer, with a snap-fit ​​gap between the two support vertical rods for a snap-fit ​​frame-type short section.

[0021] Specifically, the inner and outer support vertical rods are arranged in parallel to form a clamping structure. The width of the snap-fit ​​gap is slightly larger than the thickness of the frame-type short section, allowing the frame-type short section to be securely clamped between the two support vertical rods. Furthermore, the width of the snap-fit ​​gap can be adjusted within the range of 2-5mm to accommodate frame-type short sections of different thicknesses. This allows for quick installation and removal of the frame-type short section while ensuring connection stability.

[0022] This technical solution effectively solves the problem of a single support rod failing to securely fix the frame-type short section by using a double-support vertical rod structure. Compared with existing technologies, this clamping connection method is not only easier to install but also can withstand greater lateral loads, preventing the frame-type short section from shifting under wind or vibration. Simultaneously, the double-support structure enhances the rigidity of the overall frame, which helps maintain the structural stability of the enclosed enclosure. By adjusting the width of the clamping gap, it can also accommodate frame-type short sections of different specifications, improving the versatility of the device.

[0023] Furthermore, this application also proposes that an H-shaped connecting strip is provided between adjacent frame-type short sections, and the H-shaped connecting strip is sealed to the frame-type short sections through the slots at the upper and lower ends of the connecting strip.

[0024] The H-type connecting strip uses a metal or plastic profile with an H-shaped cross-section, and has inwardly recessed grooves on both the top and bottom sides. Specifically, the vertical web thickness of the H-type connecting strip is 3-5mm, the width of the top and bottom flanges is 20-30mm, and the groove depth is 8-12mm. As a preferred embodiment, the H-type connecting strip can be made of aluminum alloy with an anodized surface to improve corrosion resistance. During assembly, the edge of the frame-type short section can be inserted into the corresponding groove of the H-type connecting strip, and a sealing connection is achieved through a sealing strip. Furthermore, the length of the H-type connecting strip can be customized according to the dimensions of the frame-type short section.

[0025] This technical solution achieves rapid assembly and reliable sealing between adjacent frame sections using an H-type connecting strip. Specifically, the double-sided slot design of the H-type connecting strip can simultaneously secure two frame sections, ensuring the stability of the connection. The sealed connection structure effectively prevents dust leakage from the connection gaps, solving the problem of insufficient sealing at the connection points of conveyor belt enclosures in existing technologies. Compared to traditional bolted connections, this design offers advantages such as simple assembly and superior sealing performance.

[0026] Furthermore, this application also proposes that an outer frame is installed on the outer side of the frame-shaped short section at the bottom of the cover plate, and the outer frame and the frame-shaped short section have a slot for engaging the outer support vertical rod.

[0027] The outer frame can be made of metal profiles or engineering plastics. The width of the slot is slightly larger than the thickness of the support vertical rod, usually controlled within a gap range of 2-5mm. As a preferred embodiment, the outer frame is fixed to the outside of the frame section by bolts, and the depth of the slot is set to 1 / 3-1 / 2 of the height of the support vertical rod.

[0028] This technical solution achieves dual positioning of the supporting vertical rod and the cover structure by adding an outer frame with a slot to the outside of the frame-shaped short section. The outer frame not only strengthens the edge of the frame-shaped short section but also forms a plug-in fit with the supporting vertical rod through the pre-reserved slot. This simplifies the on-site installation process while ensuring the overall rigidity of the cover. Compared with existing technologies, this structure effectively solves the problem of difficult positioning of cover components during high-altitude operations, and the slot design allows for self-alignment between components, improving assembly accuracy and sealing performance.

[0029] Furthermore, this application also proposes that a connection hole for connecting the fluidized bed furnace feed box is opened on one side of the enclosed cover, and the connection hole is directly opposite the discharge port of the feeding conveyor belt.

[0030] This technical solution, by setting a precisely aligned connection interface at the end of the feeding conveyor belt, allows materials to directly enter the fluidized bed furnace's discharge box from the conveyor belt inside the enclosed enclosure, completely avoiding the dust spillage problem caused by traditional open conveyor terminals. Specifically, after the material is transported to the discharge port by the conveyor belt, it falls directly into the discharge box through a sealed connection channel, and the entire transmission process is in a fully enclosed state. This not only solves the dust pollution problem caused by high-altitude open-air conveying but also reduces material loss during transmission and improves raw material utilization. Compared with existing technologies, this structure achieves significant dust prevention effects through simple interface modifications while maintaining the original functions of the conveying system.
