Description

Technical Field

[0001] The utility model relates to the technical field of aluminum smelting and processing, in particular to a side well furnace pump room prefabricated part. Background Art

[0002] The side-well furnace is a crucial piece of equipment widely used in aluminum smelting and casting. It primarily consists of a main melting chamber and a side-well chamber. The side-well chamber is further divided into a charging area and a pumping area. The charging area is primarily used for feeding and initial processing of molten aluminum, while the pumping area is responsible for circulating and transporting the molten aluminum.

[0003] During the operation of a side-well furnace, the molten aluminum circulation pump installed in the pump area is the driving force behind the molten aluminum's movement, ensuring efficient flow between the main melting chamber and the side-well chamber. This molten aluminum circulation not only improves aluminum smelting efficiency but also ensures uniform temperature distribution, preventing overheating or undercooling in certain areas. Therefore, the design of the pump area directly impacts the efficiency of the entire aluminum smelting process and product quality.

[0004] However, the traditional pump room design has some shortcomings in practical applications. First, the structure of the pump room is usually made of cast-in-place concrete or metal materials, which has a long construction period and is difficult to ensure quality consistency. In addition, traditional pump rooms also face certain difficulties in transportation, especially in the transportation and installation of large equipment, which can easily cause delays in construction and increase costs. In order to overcome the above problems, the introduction of prefabricated technology provides a new idea for the design and manufacture of side-well furnace pump rooms. By adopting standardized and modular prefabricated parts, large-scale production can be carried out in the factory to ensure that the quality and performance of the pump room meet the design standards. At the same time, the use of prefabricated parts can effectively shorten on-site installation time, reduce construction costs, and improve engineering efficiency. To this end, we proposed a side-well furnace pump room prefabricated part. Utility Model Content

Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0026] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances. Example

[0027] The utility model provides a side well furnace pump room prefabricated part, please refer to Figures 1 to 3 , including a pump chamber 1, and a working chamber 2 arranged in the pump chamber 1, the working chamber 2 passes through the pump chamber 1, and is used to place the pumping equipment for circulating aluminum liquid; the pump chamber 1 includes a pumping passage 101, and a vent 102 arranged on one side of the pumping passage 101.

[0028] The pumping passage 101 is connected to the vortex chamber in the side well furnace; the pump chamber 1 also includes a plurality of lifting threaded holes 103 arranged on the top thereof; the working chamber 2 includes a power area 201, a mounting frame 202 arranged on one side of the power area 201, a transition area 203 arranged on one side of the mounting frame 202, and a circulation area 204 arranged on one side of the transition area 203; the pumping passage 101 is connected to the circulation area 204, and is used to drive the aluminum liquid to circulate; the vent hole 102 is connected to the power chamber 201, and is used to maintain the pressure balance inside the working chamber 2; the power chamber 201 is set to be cylindrical.

[0029] The other end of the pumping passage 101 is connected to the external side well furnace aluminum liquid flow area 3; the side well furnace aluminum liquid flow area 3 includes a vortex well preform 301, a side well furnace chamber 302 arranged on one side of the vortex well preform 301, and a side well furnace main chamber 303 connected to the side well furnace chamber 302.

[0030] It should be noted that the main body of the pump chamber 1 is composed of a special refractory castable with a certain proportion of stainless steel fiber. The power zone is a cylindrical chamber 2, which houses the circulating molten aluminum. The cylindrical structure has good strength and stability when subjected to internal pressure, effectively resisting the pressure of the fluid in the pump and reducing the risk of deformation. A channel 101 on one side of the pump chamber connects to the vortex chamber prefabricated part 301. The mechanical equipment of the pump chamber 1 rotates to deliver the molten aluminum to the vortex chamber, achieving the effect of molten aluminum circulation. Four lifting threaded holes 103 are opened on the top of the prefabricated part to facilitate the lifting and installation of the pump chamber prefabricated part.

[0031] Preferably, the mounting frame 202 is fixedly installed between the power zone 201 and the transition zone 203 by bolts, and is used to install the pumping device. In this embodiment, the pumping device uses a pumping motor, which is responsible for providing power to drive the rotation of the pump. A high-temperature resistant partition is provided between the pump and the aluminum liquid circulation zone 204 in the transition zone 203. The material is usually selected from refractory bricks, metal or high-temperature resistant plastic to prevent aluminum liquid from splashing and protect the pump equipment.

[0032] Preferably, the pump chamber preform is installed in the side well of the side well furnace and is used together with the vortex well preform 301. The flow of molten aluminum is ensured by the connecting channel of the two preforms. When the mechanical pump is installed in the pump chamber preform to stir the molten aluminum, the molten aluminum flows to the vortex well preform 301 and melts the aluminum chips thrown in here. The molten aluminum flows into the small chamber 302 of the side well through the vortex well preform, and continues to flow into the main chamber 303 of the side well furnace under the power of the aluminum liquid circulation. Finally, it recirculates into the pump chamber to realize the circulation of the aluminum liquid in the side well furnace. The circulation of the aluminum liquid can ensure the uniformity of the aluminum liquid temperature, avoid local overheating or overcooling, and more effectively utilize the heat in the furnace, making the aluminum liquid more efficient during the heating and insulation process and reducing energy consumption. Therefore, the circulation of the aluminum liquid in the side well furnace is an important link to ensure the smooth progress of the aluminum smelting and manufacturing process, and has a significant impact on the quality of the final product and production efficiency.

[0033] In summary, the side-well furnace pump chamber prefabricated parts of the present invention can be mass-produced in the factory by adopting standardized and modular prefabricated parts, ensuring that the quality and performance of the pump chamber meet the design standards, while also effectively shortening the on-site installation time, reducing construction costs, and improving engineering efficiency. In addition, the separation of the power zone and the circulation zone helps to enhance the circulation and pumping effect of the aluminum liquid, and the addition of vents helps to maintain the internal pressure balance of the working chamber, thereby enhancing the safety and stability of the pump chamber.

Any changes and modifications made by ordinary technicians in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
