Description

Technical Field

[0001] This utility model relates to the field of gas-fired crucible furnace technology, and more specifically, to a large gas-fired crucible furnace that is easy to clean. Background Technology

[0002] A crucible furnace is the simplest type of smelting equipment, mainly used for melting non-ferrous metals with relatively low melting points, such as copper, aluminum, and their alloys. In this type of furnace, the alloy melts inside the crucible, and heat is transferred to the furnace charge through the crucible. The furnace charge and combustion products do not come into direct contact, therefore the chemical composition of the alloy is almost unaffected by the furnace atmosphere, and the temperature of the molten alloy is relatively uniform—this is its main advantage. Its disadvantages include lower thermal efficiency, higher fuel consumption, smaller crucible capacity, and poorer working conditions.

[0003] According to Chinese Patent CN202222715049.8, an energy-saving gas-fired crucible furnace that is easy to clean is included. This application comprises an outer layer of the energy-saving gas-fired crucible furnace, with an inner layer fixedly disposed inside the outer layer. A fixed support is fixedly disposed on the surface of the outer layer, and a movable impurity removal component is disposed at the bottom of the inner wall of the fixed support to facilitate the removal of cleaning impurities by workers. A cleaning component is disposed on the surface of the fixed support to facilitate cleaning the interior of the energy-saving gas-fired crucible furnace. A lower electric push rod drives the output end to extend, allowing the cleaning scraper and cleaning brush to contact the inner layer of the energy-saving gas-fired crucible furnace. A drive motor then drives the output end to rotate, causing the cleaning scraper and cleaning brush to clean the inner layer of the energy-saving gas-fired crucible furnace. This achieves the goal of easy cleaning of the interior of the energy-saving gas-fired crucible furnace and avoids the blockage of the temperature measuring holes caused by impurities adhering to the interior of the energy-saving gas-fired crucible. Existing gas-fired crucible furnaces have bottom moving plates that are only adjusted by hydraulic push rods, resulting in poor stability and a lack of limiting structures, leading to lower safety.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a large gas-fired crucible furnace that is easy to clean, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A large, easy-to-clean gas-fired crucible furnace includes a furnace body. The outer wall of the furnace body has several evenly distributed connecting blocks. Each connecting block has a support column at its bottom end. The bottom end of the furnace body has a lifting plate connected to the support column via a height adjustment assembly. The top end of the lifting plate has an isolation plate extending into the furnace body. One side of the top end of the furnace body has an L-shaped mounting base. The top end of the mounting base has a rotating plate connected to the L-shaped mounting base via a rotating shaft. One side of the top end of the rotating plate has a cylinder.

The bottom end of the fixed frame has a connecting column connected to the fixed frame via a rotating shaft. One side of the connecting column has a brush connected to the connecting column via an electric push rod. The side of the connecting column away from the brush has a scraper connected to the connecting column via an electric push rod.

[0008] Preferably, the bottom end of the first rotating shaft passes through the L-shaped mounting base and is connected to the drive end of the first servo motor, and the top end of the second rotating shaft extends into the fixed frame and is connected to the drive end of the second servo motor.

[0009] Preferably, the height adjustment assembly includes a fixed plate at the bottom of the furnace body, the fixed plate being connected to the support column, a support frame at the top of the fixed plate, a worm gear in the support frame, and symmetrically arranged hollow rotating shafts at the top of the fixed plate and on both sides of the worm gear. A worm wheel matching the worm gear is fixedly sleeved on the outer wall of the hollow rotating shaft, and a lead screw is provided in the hollow rotating shaft. The top of the lead screw extends out of the hollow rotating shaft and connects to the lifting plate.

[0010] Preferably, the worm gear is connected to the upright frame via a bearing, and one side of the worm gear extends outside the upright frame and is connected to the three drive ends of the servo motor.

[0011] Preferably, the hollow rotating shaft has a threaded groove on its inner wall that matches the lead screw.

[0012] Preferably, the lead screw is welded to the lifting plate.

[0013] The beneficial effects of this utility model are as follows: by setting a height adjustment component, it is easy to raise and lower the isolation plate and fix it, which makes it convenient for personnel to clean the isolation plate. At the same time, the height adjustment component, through the cooperation of multiple sets of hollow rotating shafts, lead screws, worm gears and worm wheels, makes the raising and lowering of the isolation plate stable. In addition, the worm gear and worm wheel have a self-locking effect, which makes the isolation plate have a limit effect after the raising and lowering is completed, preventing the isolation plate from automatically descending, making it safer and more reliable.
