Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for industrial smelting equipment, and in particular to a casting chamber receiving plate, specifically a casting chamber receiving plate device for an equiaxed crystal vacuum precision casting furnace, used to receive leaked high-temperature molten metal and protect the equipment safety. Background Technology

[0002] In industrial smelting processes, especially in the field of equiaxed crystal vacuum precision casting, the mold chamber receiving tray is a critical safety component. Traditional mold chamber receiving trays typically employ a large, shallow, integrally welded steel structure, fixedly installed at the bottom of the mold chamber. Connection to the furnace body is usually achieved through welding or a large number of ordinary bolts.

[0003] This design has significant drawbacks under long-term high-temperature environments: First, if a section of the integral structure is burned through or severely deformed due to the impact of high-temperature molten metal, it cannot be repaired or replaced locally. The entire receiving tray must be disassembled and replaced, a time-consuming and labor-intensive process that typically requires downtime for hours or even days, severely impacting production efficiency. Second, traditional receiving trays have limited thermal insulation, allowing heat to easily transfer downwards, causing overheating and failure of equipment below, such as sensors or transmission mechanisms, increasing the risk of accidents. Furthermore, the fixed installation makes cleaning and maintenance difficult, requiring operators to use specialized tools, increasing labor intensity and safety hazards. Therefore, there is an urgent need for a receiving tray solution that combines replaceability, thermal insulation, and ease of operation. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model aims to solve the problems of high maintenance cost and poor heat insulation performance of traditional steel receiving trays, and provides a modular, quick-disassembly and assembly steel receiving tray for casting chambers.

[0005] The above-mentioned utility model objective is achieved through the following technical solution: This utility model provides a casting chamber receiving plate, comprising two identical plates, which are detachably connected as a whole by at least one U-shaped pin; a handle is fixedly provided on the upper part of the plate and a cylindrical welded part is provided on the bottom; the cylindrical welded part is used to raise the installation height of the plate to form a heat-insulating cavity.

[0006] According to one embodiment of the present invention, the U-shaped pin is made of high-temperature resistant alloy material, and its insertion direction is parallel to the side of the disc body. A wear-resistant bushing is provided at the connection between the U-shaped pin and the disc body.

[0007] According to one embodiment of the present invention, one side of the disc body is a rectangular shallow disc structure, and the other side is a fan-shaped shallow disc structure, with an edge height of 50-200mm, a thickness of 5-20mm, and the material is stainless steel or heat-resistant steel.

[0008] According to one embodiment of the present invention, the handle is an arc-shaped structure, welded to one side of the upper surface of the disc body, and the surface is coated with a heat-insulating coating.

[0009] According to one embodiment of the present invention, the cylindrical welded parts have a height of 100-300mm and a diameter of 50-150mm, and are arranged in multiples and welded evenly at intervals to the bottom of the disc.

[0010] According to one embodiment of the present invention, the height of the heat insulation cavity is 50-250mm, and the cavity can be filled with heat insulation material.

[0011] According to one embodiment of the present invention, the inner wall of the disc is provided with a high-temperature resistant ceramic coating with a coating thickness of 0.5-2mm.

[0012] According to one embodiment of the present invention, a temperature sensor is also included, which is embedded inside the disk body or at the bottom, for real-time temperature monitoring.

[0013] In summary, compared with the prior art, the present invention has at least one of the following beneficial technical effects: 1. This patented casting chamber receiving tray utilizes a modular, split design, improving upon the traditional integral receiving tray into a structure consisting of two identical trays connected by U-shaped pins. This enables rapid replacement in case of partial damage. When part of the tray is damaged due to the impact of high-temperature molten metal, it is not necessary to disassemble the entire device; only the damaged module needs to be replaced. This reduces maintenance time from several hours to tens of minutes, improving maintenance efficiency by over 50%, while significantly reducing spare parts costs and equipment downtime losses.

[0014] 2. In terms of safety protection, the cylindrical welded component at the bottom of the pan increases the installation height, forming an effective heat insulation cavity. This structure can significantly block the downward transfer of heat from the high-temperature molten metal. Actual measurements show that it can reduce the temperature of sensitive equipment below by about 40%, effectively avoiding equipment overheating failure caused by heat conduction, and improving the overall stability and safety of the casting chamber.

[0015] 3. Furthermore, the device excels in ease of operation and cost-effectiveness. The handle design on the upper part of the panel is ergonomic, and the simple connection method with U-shaped pins enables quick assembly and disassembly without special tools. The modular design not only reduces material waste, but its standardized components also facilitate mass production and storage, resulting in an overall cost reduction of approximately 30% compared to traditional structures. It is particularly suitable for high-temperature environments requiring frequent maintenance, such as equiaxed crystal vacuum precision casting furnaces.

[0016] 4. Improved maintenance efficiency: Modular design reduces partial replacement time from the traditional 2 hours to 10 minutes, and reduces costs by 35%; Enhanced thermal insulation: The thermal insulation cavity reduces the temperature of the equipment below by more than 40%, avoiding thermal damage; Improved safety: The handle and pin design reduces tool dependence and lowers operational risks; Wide applicability: It can be adapted to a variety of smelting equipment, and different capacity requirements can be met by adjusting the size.

[0017] This utility model discloses a casting chamber receiving tray, belonging to the field of safety protection technology for industrial smelting equipment. The device adopts a modular design, improving the traditional integral receiving tray into two identical trays that are detachably connected by a U-shaped pin. The upper part of the tray is equipped with a handle, and the bottom has a cylindrical welded component forming a heat-insulating cavity. Its innovations lie in: the split structure enabling rapid replacement in case of partial damage, reducing maintenance costs; the heat-insulating cavity effectively blocking heat transfer downwards, protecting equipment below; and the U-shaped pin connection method balancing stability and ease of assembly and disassembly. This utility model solves the problems of traditional receiving trays requiring complete replacement and resulting in low maintenance efficiency. Attached Figure Description
