[0026] This utility model provides a prefabricated aluminum water flow channel structure with a heat insulation layer. By adding a ceramic fiber board and a reflective film inside the flow channel and adding a top cover to the top of the flow channel, the heat insulation performance during the aluminum water transportation process can be significantly improved and oxidation and pollution can be reduced.

[0027] Figure 1-4 The diagram shown is a structural schematic of one embodiment of the prefabricated aluminum water channel with insulation layer according to this utility model. Please refer to [link / reference]. Figures 1-4 The prefabricated structure of an aluminum water flow channel with a heat insulation layer in this embodiment includes a base 100, a flow guide channel 200, a top cover 300, a limiting component 400, and a sealing plate 500.

[0028] The base 100 has a mounting groove 110 on its top. A flow guide 200 is located inside the mounting groove 110. The flow guide 200 includes a high-temperature contact plate 210 located inside the mounting groove 110, a ceramic fiber plate 220 connected to the outside of the high-temperature contact plate 210, a reflective film 230 connected to the outside of the ceramic fiber plate 220, and a protective shell 240 connected to the outside of the reflective film 230. The outer wall of the protective shell 240 is flush with the inner wall of the mounting groove 110. The ceramic fiber plate 220, reflective film 230, and protective shell 240 are at the same height. Top plates 210a are installed at both ends of the top of the high-temperature contact plate 210. The bottom of the top plate 210a is flush with the top of the base 100. The tops of the ceramic fiber plate 220, reflective film 230, and protective shell 240 all abut against the bottom of the top plate 210a and are flush with the top of the mounting groove 110. A protective shell 240 is installed at the inner edge of the top of the top plate 210a. The baffle 210a-1, not shown in the figure, is used in this embodiment. The high-temperature contact plate 210 is made of high-purity alumina refractory castable, and the reflective film 230 is made of aluminum foil or stainless steel foil, which is attached to the outer wall of the ceramic fiber board 220. Together with the ceramic fiber board 220, it can block heat transfer and reduce the temperature of the outer wall. The reflective film 230 reflects radiant heat, further improving the heat preservation efficiency. The protective shell 240 is made of 304 stainless steel, which fixes the heat preservation structure and prevents mechanical damage from affecting the reflective film 230 and the ceramic fiber board 220. In use, the ceramic fiber board 220, the reflective film 230 and the protective shell 240 abut against the bottom of the top plate 210a. The top plate 210a protects the ceramic fiber board 220, the reflective film 230 and the protective shell 240, and the baffle 210a-1 can prevent molten aluminum from splashing to a certain extent when the shell is open.

[0029] The top cover 300 is located on top of the guide channel 200. Vertical plates 310 are installed on both sides of the bottom of the top cover 300. The top of the baffle 210a-1 abuts against the bottom of the top cover 300. The inner wall of the vertical plate 310 is in contact with the outer wall of the baffle 210a-1. By connecting the top cover 300 to the top of the high temperature contact plate 210, the top of the high temperature contact plate 210 is sealed. A closed space is formed inside the high temperature contact plate 210 to reduce the radiative heat dissipation of the aluminum molten surface.

[0030] The base 100 has a first slot 120 on its top and a second slot 130 on its top, which is located between the first slot 120 and the mounting slot 110. The first slot 120 has a first limiting hole 130a on its side wall, which communicates with the second slot 130. The limiting assembly 400 includes a sliding plate 410 slidably connected inside the first slot 120, a spring 420 mounted on the side wall of the sliding plate 410, and a limiting rod 430 mounted on the other side wall of the sliding plate 410. The limiting rod 430 passes through the first limiting hole 130a and extends into the second slot 130. A first pull plate 410a is mounted on the top of the sliding plate 410. 10a extends from the top of the first slot 120. A fixing plate 210b is installed at the bottom of the top plate 210a. The fixing plate 210b is located inside the second slot 130. A T-slot 210b-1 is formed at the top of the fixing plate 210b. A second limiting hole 210b-2 is formed on the side wall of the fixing plate 210b at the position corresponding to the first limiting hole 130a. A horizontal plate 320 is installed at the bottom of the vertical plate 310. The bottom of the horizontal plate 320 abuts against the top of the top plate 210a. A T-shaped plate 320a is installed at the bottom of the horizontal plate 320. The T-shaped plate 320a extends into the T-slot 210b-1. A third limiting hole 320a is formed on the side wall of the T-shaped plate 320a at the position corresponding to the second limiting hole 210b-2. -1. When it is necessary to replace the ceramic fiber board 220 and the reflective film 230, pull the sliding plate 410 into the first slot 120 and squeeze the spring 420. The limiting rod 430 slides into the first slot 120 along with the sliding plate 410. The limiting rod 430 is then pulled out from the second limiting hole 210b-2 and the third limiting hole 320a-1. At this time, push the top cover 300 to drive the T-shaped plate 320a to separate from the T-shaped groove 210b-1. Pull the high-temperature contact plate 210 to separate from the top of the base 100. The high-temperature contact plate 210 separates from the ceramic fiber board 220. The fixing plate 210b separates from the second slot 130. At this time, the ceramic fiber board 220 and the reflective film 230 are... Replacement is performed by replacing the outer wall. After replacing the outer wall, push the high-temperature contact plate 210 downwards. The outer wall of the high-temperature contact plate 210 abuts against the inner wall of the ceramic fiber plate 220. The fixing plate 210b extends into the second slot 130. At the same time, push the top cover 300 to slide in the direction of the guide channel 200. The T-shaped plate 320a extends into the T-shaped groove 210b-1. Release the slide plate 410. The spring 420 rebounds and pushes the slide plate 410 and the limiting rod 430 to move in the direction of the second slot 130. The limiting rod 430 passes through the third limiting hole 320a-1 and the second limiting hole 210b-2, connecting and fixing the high-temperature contact plate 210 inside the mounting groove 110. The top cover 300 is fixed on the top of the guide channel 200.

[0031] The top cover 300 has multiple pressure relief holes 330 extending to the bottom of the top cover 300. Two guide grooves 340 are symmetrically formed on the top of the top cover 300 around the pressure relief holes 330, but do not extend to the bottom of the top cover 300. A sealing plate 500 is slidably connected to the top of the top cover 300. Two guide plates 510 are symmetrically installed on the bottom of the sealing plate 500, located inside the guide grooves 340. A sealing sheet 520 is installed on the bottom of the sealing plate 500, positioned between the two guide plates 510 and above the pressure relief holes 330. A second pull is installed on the top of the sealing plate 500. In the initial state, the sealing plate 500 and the guide plate 510 block multiple pressure relief holes 330. At this time, the high-temperature contact plate 210 and the top cover 300 are sealed. However, the molten aluminum may release gases such as flux volatiles and hydrogen at high temperatures. The completely sealed cover may cause the internal pressure to rise, affecting the flow rate of the molten aluminum or causing splashing. At this time, the second pull plate 530 is pulled to make the sealing plate 500 slide on the top of the top cover 300, and the guide plate 510 slides inside the guide groove 340, exposing a sufficient number of pressure relief holes 330. Pressure relief and exhaust operations are performed inside the high-temperature contact plate 210 through the pressure relief holes 330.

[0032] Combination Figures 1-4 In this embodiment, a prefabricated aluminum water trough structure with a heat insulation layer is used. First, the protective shell 240 is installed inside the mounting groove 110. Then, a reflective film 230 and a ceramic fiber board 220 are attached to the inner wall of the protective shell 240 in sequence. Pulling the sliding plate 410 causes the limiting rod 430 to slide into the first slot 120 and compress the spring 420. The high-temperature contact plate 210 is inserted into the mounting groove 110, and the outer wall of the high-temperature contact plate 210 abuts against the inner wall of the ceramic fiber board 220. The fixing plate 210b extends into the second slot 130. At the same time, the top cover 300 is pushed to slide to the top plate. At the top of 210a, the T-shaped plate 320a extends into the T-shaped groove 210b-1. At this time, the sliding plate 410 is released, and the spring 420 rebounds, pushing the sliding plate 410 and the limiting rod 430 to move towards the second slot 130. The limiting rod 430 passes through the second limiting hole 210b-2 and the third limiting hole 320a-1, completing the installation of the guide groove 200 and the top cover 300. During use, the sealing plate 500 is slid by pulling the second pull plate 530, exposing or closing the pressure relief hole 330 to prevent the high-temperature contact plate 210 from affecting the flow rate of molten aluminum due to increased pressure.
