Description

Technical Field

[0001] This utility model relates to the field of hot melt furnace lifting tools, specifically a lifting tool device for replacing copper alloy hot melt furnaces. Background Technology

[0002] The copper alloy melting furnace is a new type of high-efficiency and energy-saving furnace with a melting point as high as 1400℃. It is used for melting and processing aluminum ingots and copper granules (silver-copper alloy). When the copper alloy furnace is shut down for furnace body replacement, the furnace wall temperature is very high immediately after the furnace stops running. It is necessary to continuously supply water to the furnace heating coils to cool them down and prevent coil damage. The water supply can only be stopped and the furnace body replaced when the furnace wall temperature drops below 100℃. The furnace body cooling time is generally 12-15 hours. Then the furnace is replaced by gantry crane and lifting equipment. However, the fact that the furnace can only be replaced after the furnace heating coils have cooled down greatly prolongs the furnace replacement time and reduces production efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0013] Please see Figure 1-2 This utility model provides a technical solution: a lifting device for replacing a copper alloy hot melt furnace, including a lifting ring 3 on a lifting plate 1, a lifting hook 2 on the bottom surface of the lifting plate 1, a cooling water tank 4 fixedly mounted on the top surface of the lifting plate 1, a water supply pipe 7 and a return pipe 8 on one side wall of the cooling water tank 4, a high-pressure water pump 5 fixedly mounted on the top surface of the lifting plate 1, and the inlet of the high-pressure water pump 5 connected to the water supply pipe 7; a water radiator 9 is also provided on one side of the top surface of the lifting plate 1 located in the cooling water tank 4.

[0014] The water radiator 9 includes two vertically arranged manifolds 91, with multiple horizontally arranged flat tubes 92 between the manifolds 91 and heat dissipation fins 93 between the flat tubes 92. One side of the manifold 91 has a water inlet, and the other side of the manifold 91 has a water outlet. Multiple cooling fans 10 are fixedly installed on the water radiator 9, and the outlet of the high-pressure water pump 5 is connected to the inlet of the water radiator 9 through a connecting pipe. The outlet of the water radiator 9 is connected to an inlet pipe 6.

[0015] The return water pipe 8 is equipped with a temperature sensor 14, and the hanging plate 1 is equipped with a digital display controller 13; both the inlet water pipe 6 and the return water pipe 8 are connected to high temperature resistant hoses 11, and the hanging plate 1 is equipped with heat insulation baffles 12 at the positions corresponding to the high temperature resistant hoses 11.

[0016] Working principle:

[0017] When the copper alloy furnace needs to be replaced after shutdown, the external gantry crane is engaged with the lifting ring 3 on the lifting plate 1, and the lifting device is lifted onto the furnace using the external gantry crane. The high-temperature resistant hose 11 connected to the inlet pipe 6 is connected to the cold water inlet on the furnace, and the high-temperature resistant hose 11 connected to the return pipe 8 is connected to the cold water outlet on the furnace. The high-temperature resistant hose 11 is insulated and protected by the heat insulation baffle 12. The cooling fan 10 and high-pressure water pump 5 are started by the digital display controller 13. The high-pressure water pump 5 delivers the cooling water in the water radiator 9 to the cooling chamber of the furnace through the inlet pipe 6, thereby cooling the heating coils of the furnace. The water in the cooling chamber of the furnace flows back to the cooling water tank 4 through the return pipe 8, cooling the furnace. Water in water tank 4 is delivered to water radiator 9 through water pipe 7 and high-pressure water pump 5, and the water in water radiator 9 is cooled by cooling fan 10, thereby achieving continuous cooling of furnace heating coil; after the cooling pipe of furnace and lifting device is connected, hook 2 is connected to furnace hook, and furnace is lifted to the furnace offline storage area by external gantry crane, thereby completing the rapid replacement of furnace; the water temperature in return water pipe 8 is detected by temperature sensor 14 and displayed on digital display controller 13, so that the approximate temperature of furnace heating coil can be roughly determined; when the water temperature in return water pipe 8 is lower than the set value, cooling fan 10 and high-pressure water pump 5 stop working, and gantry crane detaches lifting device from furnace;

[0018] The lifting device disclosed in this embodiment for replacing copper alloy hot melting furnace continuously cools the heating coil of the furnace through a water radiator 9, a water inlet pipe 6, a water return pipe 8, a high-pressure water pump 5, and a cooling fan 10 installed on the lifting device.
