[0031] As Figures 1 to 4As shown, a heat-insulating furnace for aluminum-based composite materials includes a furnace body 1, and further includes:
[0032] The liquid filling chamber 2, the first degassing chamber 3, the second degassing chamber 4, and the liquid outlet chamber 5 are arranged in parallel inside the furnace body 1. The liquid filling chamber 2 and the first degassing chamber 3, the first degassing chamber 3 and the second degassing chamber 4, and the second degassing chamber 4 and the liquid outlet chamber 5 are all connected by a connecting port 6, which is located near the bottom of the furnace body 1.
[0033] The filter plate 7, which is located inside the connection port 6, is used to filter and purify the molten aluminum.
[0034] The liquid inlet 13 is located between the outside of the furnace body 1 and the liquid filling chamber 2, and the liquid inlet 13 is close to the top of the furnace body 1.
[0035] A first liquid outlet 14 and a second liquid outlet 15 are provided between the outside of the furnace body 1 and the liquid outlet chamber 5. The first liquid outlet 14 is used to release aluminum liquid normally, and the second liquid outlet 15 is used to drain the aluminum liquid.
[0036] Two sealing valves 16 are respectively installed inside the first liquid outlet 14 and the second liquid outlet 15.
[0037] Four heat-insulating covers 9 are respectively installed on the top of the liquid addition chamber 2, the first degassing chamber 3, the second degassing chamber 4, and the liquid outlet chamber 5.
[0038] The cleaning cover 18, located on the heat preservation cover 9, can be opened after the aluminum liquid has been drained, making it convenient for cleaning personnel to clean the interior of the liquid filling chamber 2, the first degassing chamber 3, the second degassing chamber 4, and the liquid outlet chamber 5.
[0039] By placing the connecting port between the bottoms of two adjacent chambers, airflow between adjacent chambers can be greatly reduced, oxygen in the furnace can be reduced, thereby reducing oxides generated in the molten aluminum, improving the cleanliness of the molten aluminum, and reducing the amount of cleaning work.
[0040] like Figures 2 to 4 As shown, the heat preservation furnace for aluminum-based composite materials also includes a drain slide 17 fixedly disposed outside the furnace body 1, and one end of the drain slide 17 is connected to the second liquid outlet 15.
[0041] The bottom of the inside of the liquid outlet chamber 5 and the bottom of the inside of the second liquid outlet 15 are flush, and when the liquid aluminum is exhausted, the second liquid outlet 15 is opened, so that the liquid aluminum in the liquid adding chamber 2, the first degassing chamber 3, the second degassing chamber 4 and the liquid outlet chamber 5 can be completely discharged, avoiding the problem of residual cooling and solidification, which is difficult to clean. The height of the second liquid outlet 15 is lower than the height of the first liquid outlet 14. Due to the close distance between the first liquid outlet 14 and the liquid surface of the liquid aluminum, the liquid pressure of the liquid aluminum near the first liquid outlet 14 is relatively small, and the impact force when the liquid aluminum is discharged is also relatively small, which is convenient for taking the liquid aluminum in a certain amount, avoids the splashing of the liquid aluminum when the liquid aluminum is taken, and improves the safety of taking the liquid aluminum.
[0042] As shown in Figure 1 , the bottoms of the inside of the liquid adding chamber 2, the first degassing chamber 3, the second degassing chamber 4 and the liquid outlet chamber 5 are flush.
[0043] The bottoms of the inside of the three communication openings 6 are flush, and the bottoms of the inside of the communication openings 6 are flush with the bottom of the inside of the liquid adding chamber 2. This design can make the liquid aluminum flow from the bottoms of the inside of the liquid adding chamber 2, the first degassing chamber 3, the second degassing chamber 4 and the liquid outlet chamber 5, effectively avoiding the flow of gas between the inside of the liquid adding chamber 2, the first degassing chamber 3, the second degassing chamber 4 and the liquid outlet chamber 5, reducing the oxides generated by the liquid aluminum in the liquid adding chamber 2, the first degassing chamber 3, the second degassing chamber 4 and the liquid outlet chamber 5, and improving the purification efficiency of the liquid aluminum.
[0044] As shown in Figure 1 and Figure 4 , the aluminum-based composite material holding furnace further comprises three gas permeable bricks 12 arranged in a triangular shape in the first degassing chamber 3. The gas permeable bricks 12 can remove the gas and inclusions in the liquid aluminum flowing into the first degassing chamber 3, purify the liquid aluminum, and avoid the problem of bubbles and pores in the liquid aluminum after the liquid aluminum is cooled and shaped. One of the heat preservation covers 9 is provided with a perforation 11, which communicates between the outside of the heat preservation cover 9 and the second degassing chamber 4. The outside of the furnace body 1 is provided with a degassing machine 10, and the output end of the degassing machine 10 extends into the inside of the second degassing chamber 4 through the inside of the perforation 11. The degassing machine 10 is used to stir the liquid aluminum and remove the gas in the liquid aluminum, and can also add the required powder material to the liquid aluminum synchronously, and improve the mixing uniformity of the added material through stirring.
[0045] As shown in Figure 1 , the aluminum-based composite material holding furnace further comprises three heaters 8 arranged horizontally and side by side in the liquid adding chamber 2. The first degassing chamber 3, the second degassing chamber 4 and the liquid outlet chamber 5 are also provided with three heaters 8. This design uses the horizontal immersion type heater 8 in combination with the degassing machine 10 and the gas permeable brick 12, which not only can directly transfer heat, but also can make the internal thermal convection of the liquid aluminum, improve the heating efficiency of the liquid aluminum, improve the thermal efficiency and reduce the heat loss, and also can reduce the burning loss of aluminum.
[0046] Working principle: first start the heater 8, then add the liquid from the liquid inlet 13 to the inside of the liquid chamber 2, because the liquid chamber 2, the first degassing chamber 3, the second degassing chamber 4 and the liquid outlet chamber 5 are communicated through the communication port 6, the liquid can flow into the liquid chamber 2, the first degassing chamber 3, the second degassing chamber 4 and the liquid outlet chamber 5 in turn, after the liquid level is higher than the bottom of the communication port 6, because the inside of the first degassing chamber 3 and the liquid outlet chamber 5 forms a relatively sealed state, open the cleaning cover 18, so that the liquid level inside the four is kept flush, until the liquid level reaches the standard, stop adding liquid and close the cleaning cover 18, then control the degassing machine 10, make its output end drop and pass through the perforated hole 11 on the heat preservation cover 9 at the top of the second degassing chamber 4, until it is deep into the liquid to a certain depth, then start the degassing machine 10 and the air brick 12, the air brick 12 blows inert gas or active gas into the liquid in the first degassing chamber 3, the gas is combined with the gas in the liquid and then discharged, so as to achieve the effect of degassing, at the same time, the gas combined with the gas in the liquid rises out of the liquid, which will drive the heat synchronously, improve the uniformity of the liquid heating, through the operation of the degassing machine 10 and the agitation of the liquid in the second degassing chamber 4, the degassing effect of the liquid is further improved, and powder material is added into the liquid at the same time, the agitated liquid can accelerate the addition of the material to be melted into uniformity and efficiency, at the same time, the hot convection is formed in the liquid, which further improves the uniformity and efficiency of the liquid heating, and greatly reduces the contact between the liquid and the outside air, so as to reduce the oxide produced in the furnace body 1, and when the liquid passes through all the communication ports 6 in turn, it will be filtered and purified by the filter plate step by step, improving the purification effect of the liquid; when the appropriate amount of liquid is needed, open the sealing valve 16 in the first liquid outlet 14, because the distance between the first liquid outlet 14 and the liquid level is relatively small, the impact force of the liquid when it is released is relatively small, which can avoid the problem of splashing liquid to cause injury to personnel or equipment, improving the safety of liquid taking; when the liquid needs to be discharged, open the sealing valve 16 in the second liquid outlet 15, because the distance between the second liquid outlet 15 and the liquid level is relatively large, the impact force of the liquid when it is released is large, which can bind the liquid through the liquid discharge slide 17, avoid the situation that the liquid splashes everywhere to cause injury to personnel and equipment, improve the safety of liquid discharge operation, and also facilitate the concentrated collection of precise collection of liquid, avoid waste.
