Description

Technical Field

[0001] This application relates to the field of fluidized bed furnaces, and in particular to a fluidized bed furnace with a slag removal mechanism. Background Technology

[0002] Currently, fluidized bed furnaces are widely used as key equipment in the gypsum powder production industry for material heating and processing. With the continuous growth of industry demand and technological advancements, improving equipment operating efficiency, reducing maintenance costs, and minimizing environmental pollution have become important research directions in this field. However, in actual production, the accumulation of ash and slag after long-term operation of the fluidized bed furnace remains a critical factor affecting equipment performance and the working environment. In severe cases, it can even lead to equipment failure or secondary pollution, hindering the further development of the industry.

[0003] In related technologies, a common method is to add an inclined ramp to the bottom of the storage silo, along with a manual inspection port, to allow professional personnel to enter the confined space to carry out manual removal operations.

[0004] The aforementioned technologies have the following drawbacks: manual cleaning is extremely labor-intensive. Utility Model Content

[0005] To reduce the labor intensity of workers, this application provides a fluidized bed furnace with a slag removal mechanism.

[0006] The fluidized bed furnace with a slag removal mechanism provided in this application adopts the following technical solution:

[0007] A fluidized bed furnace with a slag removal mechanism includes a furnace body, a blower, multiple cover plate units and a dust collection unit, wherein the bottom of the furnace body is connected to the air outlet of the blower.

[0008] The furnace wall is provided with multiple dust removal holes;

[0009] Multiple cover plate units are correspondingly provided with multiple dust removal holes. The cover plate units are installed on the furnace wall and are used to control the opening and closing of the corresponding dust removal holes.

[0010] The vacuuming unit includes a vacuum cleaner and multiple vacuum hoods, the vacuum cleaner being detachably connected to the multiple vacuum hoods;

[0011] Multiple dust suction hoods are correspondingly arranged with multiple cover plate units. The dust suction hoods are detachably installed on the furnace wall and are used to suck up the ash and slag discharged from the dust removal hole.

[0012] By adopting the above technical solution, during dust removal, the cover plate units are opened in sequence, and the vacuum cleaner is connected to the corresponding dust hood of the opened cover plate unit in sequence. Then, the vacuum cleaner sucks away the ash and slag that need to be discharged from multiple dust removal holes in sequence, realizing the automatic collection of ash and slag, thereby reducing the labor intensity of workers.

[0013] Preferably, the furnace body has multiple waste troughs at the bottom;

[0014] The furnace bottom is also provided with a mesh plate mounted on multiple waste troughs, and the mesh plate is detachably connected to the furnace body.

[0015] The air outlet of the blower is connected to the bottom of the waste trough.

[0016] By adopting the above technical solution, multiple waste troughs are set at the bottom of the furnace, and the mesh plate is connected to the blower, allowing hot air to be blown in from the bottom of the waste troughs. This effectively promotes the boiling effect of the materials inside the furnace, while also facilitating the temporary storage of ash and slag in the waste troughs, preventing them from accumulating directly at the bottom of the furnace and affecting the normal operation of the equipment. This design significantly improves the working efficiency and stability of the fluidized bed furnace and reduces the difficulty of ash and slag cleaning.

[0017] Preferably, the dust removal holes are located at one end of the furnace wall near the furnace bottom, and a plurality of the dust removal holes are distributed circumferentially along the furnace bottom.

[0018] By adopting the above technical solution, the dust removal holes are located at one end of the furnace wall near the furnace bottom, and multiple dust removal holes are distributed circumferentially along the furnace bottom. This allows ash and slag to be discharged from the furnace more evenly, avoiding blockage problems that may be caused by localized concentrated dust discharge. At the same time, this layout helps to improve the working efficiency of the dust collection unit, ensuring a more thorough and efficient ash and slag cleaning process.

[0019] Preferably, the cover plate unit includes a connecting ring, a sealing cover, and a guide plate, with one end of the connecting ring installed on the furnace wall;

[0020] The sealing cap is located at the other end of the connecting ring;

[0022] By adopting the above technical solutions, the connecting ring in the cover plate unit achieves a stable connection with the furnace wall, ensuring structural reliability; the sealing cover effectively seals the dust removal hole, preventing ash and slag from leaking when not in operation, and improving the sealing performance of the equipment; the guide plate is set at an inclination to guide the ash and slag to flow smoothly from the bottom of the furnace to the dust removal hole, optimizing the cleaning path and improving the slag removal efficiency.

[0023] Preferably, the connecting ring is detachably connected to the furnace wall.

[0024] By adopting the above technical solution, the design of the detachable connection between the connecting ring and the furnace wall makes the installation and disassembly of the cover plate unit more convenient. This structure facilitates regular maintenance, replacement, or cleaning of the cover plate unit, thereby ensuring the long-term stable operation of the fluidized bed furnace slag removal mechanism, while reducing maintenance costs and time consumption caused by component damage or blockage.

[0025] Preferably, the dust suction hood is positioned above the corresponding cover plate unit and is slidably connected to the furnace wall in the vertical direction.

[0026] By adopting the above technical solution, and adjusting the height of the dust hood, it can be lowered to cover the open cover unit when vacuuming is needed. When the cover unit requires maintenance, the dust hood can be moved upwards away from the cover unit, without interfering with maintenance.

[0027] Preferably, the dust extraction hood includes a conical hood and a U-shaped plate, wherein the conical hood is slidably connected to the furnace wall in the vertical direction;

[0028] The U-shaped plate is vertically positioned below the conical cover to cover the cover plate unit, and one end is connected to the dust suction port of the conical cover.

[0029] The suction port of the vacuum cleaner is detachably connected to the dust outlet of the conical hood.

[0030] Preferably, the dust collection unit further includes a slide rail, a first slider, and a second slider, wherein the slide rail is vertically mounted on the furnace wall;

[0031] Both the first slider and the second slider are slidably connected to the slide rail, and the first slider is located above the second slider;

[0032] The vacuum cleaner is mounted on the first slider;

[0033] The conical cover is mounted on the second slider.

[0034] By adopting the above technical solution, the slide rail in the dust collection unit is vertically installed on the furnace wall, and the first and second sliders are slidably connected to the slide rail, allowing the vacuum cleaner and the conical hood to be installed on the first and second sliders respectively and move up and down. This design allows for flexible adjustment of the positions of the vacuum cleaner and the conical hood, ensuring that the vacuum cleaner's suction port can be accurately aligned with the cover plate unit, improving dust collection efficiency. It also facilitates the disassembly and maintenance of the vacuum cleaner and the conical hood, allowing the vacuum cleaner to be moved on the ground or mounted on the furnace wall for dust collection, depending on the actual situation, facilitating the switching of the vacuum cleaner's working position.

[0035] Preferably, the vacuum cleaner's suction port is equipped with a suction hose that is detachably connected to the dust outlet of the conical hood.

[0036] By adopting the above technical solution, the vacuum cleaner and the cone are detachably connected using a vacuum hose, ensuring reliable airflow transmission between the two, enhancing the adaptability and stability of the vacuum unit, facilitating independent maintenance, replacement or position adjustment of the vacuum cleaner and the cone, and improving the flexibility and service life of the equipment.

[0037] In summary, this application includes at least one of the following beneficial technical effects:

[0038] 1. In this application, by setting multiple dust removal holes in the furnace wall and cooperating with a detachable cover plate unit and a dust collection unit, the ash and slag cleaning operation is automated, which significantly reduces the degree of manual intervention and reduces labor intensity and cost.

[0039] 2. The modular design of the cover plate unit and dust collection unit adopted in this application makes it easy to adjust and maintain according to actual needs, avoiding the problem that traditional integrated structures cannot easily remove residues when severely clogged, thus improving the operating efficiency and stability of the equipment.
