Description

Technical Field

[0001] The utility model relates to a soft flow trough for casting molten aluminum. Background Art

[0002] The soft flow trough is a flexible structure device connected to the end moving equipment of the aluminum water metal tank cabinet production line, and can withstand the flow of 800℃ aluminum water solution. The soft flow trough must be able to withstand the high temperature and the weight flow, and withstand the pulling and tearing action caused by the up and down movement of the machine.

[0003] For a long time, the industry has used soft metal structure chutes for flowing and pouring. The soft metal structure chutes are inconvenient to disassemble and assemble, and the disassembly and assembly precision is relatively high, so professional personnel are required for disassembly and assembly. After two or three furnaces in the early stage of use, the flow is not smooth and aluminum liquid is stained. The more it is stained, the more aluminum liquid is stained. When pouring, the overall structure is distorted after the up and down movement, and the connection parts are torn and damaged to leak aluminum liquid. It is very difficult to clean the inner wall of the chute after each furnace. The service life of the soft metal chute is very short, generally not more than 15 furnaces. Utility Model Content

[0006] In some embodiments, the Secka fiber material layers located inside and outside the silicate needle felt are sewn into a quilt shape.

[0007] In some embodiments, the gasket is U-shaped.

[0008] In some embodiments, it also includes a device flange clamped inside and outside the gasket, and the gasket and the device flange are connected by bolts and nuts.

[0009] In some embodiments, a buffer support plate is provided on the bottom of the equipment flange located on the outside.

[0010] In some embodiments, the soft flow channel body is tapered in the longitudinal direction.

[0019] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0020] like Figure 1-5 The aluminum casting soft flow trough shown comprises a soft flow trough body 1 and gaskets 2 sewn to both ends of the soft flow trough body 1. Four towing straps 5 are sewn to the soft flow trough body 1 for bearing the weight of the soft flow trough body 1. The towing straps 5 are pre-perforated with buckles for easy connection.

[0021] The soft flow trough body 1 comprises a silicate needle felt 12 and a Secka fiber material layer 11 and a Secka fiber material layer 13 located inside and outside the silicate needle felt 12. The Secka fiber material layer 11 and the Secka fiber material layer 13 are sewn into a quilt shape, and the silicate needle felt 12 is filled therein, so that the soft flow trough body 1 has elasticity, thereby having excellent anti-scouring and anti-impact capabilities.

[0022] The soft flow tank body 1 can withstand the flow of 800°C aluminum solution and has a strong load-bearing capacity. The gasket 2 is made of three layers of Secka fiber material 22, and the suture line 21 is as follows. Figure 2 As shown, it can withstand temperatures above 800 degrees.

[0023] The gasket 2 is formed by sewing three layers of Secka fiber material layers 22, and is sewn at both ends of the soft flow channel body 1, thereby improving the load-bearing capacity and the tensile and tearing resistance of the soft flow channel. In addition, the silicate needle felt 12, the Secka fiber material layer 11, the Secka fiber material layer 13 and the Secka fiber material layer 22 are sewn together, and are easy to disassemble and assemble.

[0024] The silicate needle felt 12, the Secka fiber material layer 11, the Secka fiber material layer 13 and the Secka fiber material layer 22 can withstand a high temperature of 800 degrees, and have excellent characteristics of anti-scouring, anti-impact, resistance to rapid cooling and heating, non-sticking to aluminum, no chemical reaction with aluminum, and a small thermal expansion coefficient. At the working temperature, the aluminum solution can be kept at a constant temperature, and it does not absorb moisture, does not pollute the aluminum solution, has a firm structure, and the continuous working service life of the soft flow trough structure is not less than 25 furnaces.

[0025] The soft flow trough body 1 is tapered in the longitudinal direction, so that the aluminum liquid can pour and flow smoothly. The inner side of the soft flow trough body 1 is coated with lubricating powder, so that the aluminum liquid pours and flows more smoothly, and there is no need to clean the inner wall of the soft flow trough after work.

[0026] The gasket 2 is U-shaped. It also includes a device flange 31 and a device flange 32 clamped inside and outside the gasket 2, and the device flange 31 and the device flange 32 are also U-shaped. The gasket 2 is provided with a mounting hole 20, the device flange 31 is provided with a mounting hole 310, and the device flange 32 is provided with a mounting hole 320. The gasket 2 and the device flange 31 and the device flange 32 are connected by bolts and nuts 4. A buffer support plate 321 is provided at the bottom of the device flange 32 located on the outside.

[0027] The connection parts between the soft flow trough body 1 and the equipment flanges 31 and 32 are sewn and reinforced with multiple layers of Secka fiber material layers 22, thereby ensuring the tensile and tearing resistance and load-bearing capacity of the soft flow trough.
