Description

Technical Field

[0001] The utility model relates to the technical field of foam aluminum production, in particular to a cooling device for foam aluminum. Background Art

[0002] At present, the preparation process of foamed aluminum mostly adopts the melt foaming method. When using this method to prepare foamed aluminum, after the stirring process is completed, the foamed aluminum in the forming mold needs to be transferred to the insulation, cooling and demolding equipment in sequence. Among them, for the foamed aluminum after insulation and furnace, it is usually cooled by spraying cooling water. However, since foamed aluminum is made by adding additives to pure aluminum or aluminum alloy and then undergoing a foaming process, it has both metal characteristics and bubble characteristics, which makes it difficult for the sprayed cooling water to enter the pores on the foamed aluminum, which not only wastes water resources, but also reduces the cooling efficiency of the foamed aluminum. Utility Model Content

[0003] The utility model provides a cooling device for foamed aluminum to solve the problem that when foamed aluminum is sprayed with cooling water after being heat-insulated and taken out of the furnace, the cooling efficiency is low because the cooling water is difficult to enter the holes. The contact time and contact area between the foamed aluminum and the cooling water are increased, and a water film is applied on the surface of the foamed aluminum to take away the heat of the foamed aluminum itself by means of thin film evaporation, thereby greatly reducing the temperature of the foamed aluminum after being heat-insulated and taken out of the furnace.

[0004] The technical solution adopted by the utility model is:

[0005] A cooling device for foamed aluminum is provided, comprising:

[0006] A cooling pool, the bottom of which is provided with a feed port, the inner wall of the cooling pool is provided with a plurality of inclined plates inclined toward the top thereof, the plurality of inclined plates are cross-arranged, and a gap is provided between each inclined plate and the inner wall of the cooling pool for the foam aluminum to pass through;

[0007] A feed pipe is obliquely arranged on the outer wall of the cooling pool and is connected to the feed port;

[0008] A box body has an opening and an outlet, the box body is arranged on the outer side wall of the cooling pool and communicates with the top of the cooling pool through the opening;

[0009] A coating component is arranged on the inner top of the box body and is used to apply a water film to the surface of the foam aluminum;

[0010] Among them, the inside of the feed pipe, the inside of the box body and the top of the cooling pool are all provided with a conveying mechanism for conveying foam aluminum.

[0011] In some embodiments of the utility model, the conveying mechanism is a belt conveying mechanism, and a baffle with an L-shaped cross-section is vertically arranged on the belt used for conveying, and a water leakage hole is opened on the baffle.

[0012] In some embodiments of the utility model, a heat exchanger with a liquid inlet and a liquid outlet is provided on the outer wall of the cooling pool, the liquid inlet of the heat exchanger is connected to a liquid inlet pipe extending to the interior of the cooling pool, the liquid inlet pipe is provided with a water pump, and the liquid outlet of the heat exchanger is connected to a liquid outlet pipe extending to the interior of the cooling pool.

[0013] In some embodiments of the utility model, the coating assembly includes a fixed rod, a fixed block and a brush, the fixed rod is vertically arranged on the inner top of the box body, the fixed block is arranged on the free end of the fixed rod, the brush is arranged at the bottom of the fixed block, a liquid storage cavity is opened inside the fixed block, a water inlet is opened on the side wall of the fixed block, a water outlet is opened at the bottom of the fixed block, and a water pipe connected to the water inlet is penetrated through the side wall of the box body.

[0014] In some embodiments of the utility model, a reset ball valve with a handle is provided on the water pipe, and the handle of the reset ball valve is in periodic sliding contact with a baffle in the conveying mechanism located in the box body.

[0017] In some embodiments of the present invention, a liquid inlet channel extending to the interior of the cooling pool is opened on the side wall of the box body, and the liquid inlet channel is connected to a relatively lower side of the inner bottom of the box body.

[0018] The beneficial effects of the utility model are:

[0019] 1. Put the foamed aluminum that has been insulated and taken out of the furnace into the feed pipe. The conveying mechanism in the feed pipe conveys the foamed aluminum to the feed port at the bottom of the cooling pool. Since the cooling pool is filled with cooling water and the density of the foamed aluminum is less than that of water, the foamed aluminum entering from the bottom will float from the bottom of the cooling pool to the liquid surface of the cooling water in the cooling pool. In this process, the foamed aluminum can fully contact with the cooling water, and the water pressure at the bottom of the cooling pool is high, which can press the cooling water into the porous internal position of the foamed aluminum, so that the foamed aluminum and the cooling water are in contact for a long time and over a large area, and the cooling efficiency is obvious;

[0020] 2. A conveying mechanism is set at the position where the top of the cooling pool is connected to the opening of the box, which can convey the foam aluminum floating on the liquid surface in the cooling pool to the inside of the box. The foam aluminum entering the inside of the box will fall on the conveying mechanism located in the box for conveying foam aluminum. A coating component is set on the inner top of the box. When the conveying mechanism transports the foam aluminum, water can be applied to the surface of the foam aluminum to form a thin water film, and then the heat of the foam aluminum can be taken away by the evaporation of the water film, thereby realizing double cooling treatment.

[0028] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0029] The embodiments of the utility model are described in detail below with reference to the accompanying drawings. Example

[0030] like Figure 1 As shown, this embodiment provides a cooling device for foam aluminum, comprising:

[0031] A cooling pool 1 is provided with a feed port 10 at the bottom, and a plurality of inclined plates 11 inclined toward the top of the cooling pool 1 are provided on the inner wall thereof, wherein the plurality of inclined plates 11 are arranged crosswise, and a gap is provided between each inclined plate 11 and the inner wall of the cooling pool 1 for the foam aluminum to pass through;

[0032] The feed pipe 2 is obliquely arranged on the outer wall of the cooling pool 1 and is connected to the feed port 10;

[0033] The box body 3 has an opening 30 and an outlet 31. The box body 3 is arranged on the outer wall of the cooling pool 1 and communicates with the top of the cooling pool 1 through the opening 30;

[0034] The coating component is arranged at the inner top of the box body 3 and is used to apply a water film to the surface of the foam aluminum;

[0035] The inside of the feed pipe 2, the inside of the box 3 and the top of the cooling pool 1 are all provided with a conveying mechanism 20 for conveying foamed aluminum.

[0036] The feed pipe 2 is obliquely arranged on the outer wall of the cooling pool 1, one end of which is used to feed the foam aluminum, and the other end of which feeds the foam aluminum into the cooling pool 1. After the cooling pool 1 is filled with cooling water, since the feed pipe 2 and the cooling pool 1 are connected, according to the principle of communicating vessels, there will also be cooling water in the feed pipe 2, and the conveying mechanism 20 in the feed pipe 2 should have the function of being able to feed the foam aluminum with a density less than that of water to the bottom of the water. Therefore, in this embodiment, a chain conveying mechanism 20 can be selected, and the conveying chain has a vertical plate that can block the foam aluminum entering the cooling water to prevent it from floating. It is worth noting that the distance between the conveying mechanism 20 in the feed pipe 2 and the inner wall of the feed pipe 2 is smaller than the height of the foam aluminum to prevent the foam aluminum from running out from the gap between the conveying mechanism 20 and the feed pipe 2 when the foam aluminum enters the cooling pool 1 from the feed pipe 2. The conveying mechanism 20 at the top of the cooling pool 1 places its input end in the cooling water in the cooling pool 1, and the output end faces the side of the box 3, that is, after the conveying mechanism 20 at the top of the cooling pool 1 is in operation, the foam aluminum floating in the cooling water can be conveyed to the inside of the box 3. There are at least two inclined plates 11 in the cooling pool 1, and there is a gap between the inclined plate 11 and the inner wall for the foam aluminum to pass through.

[0037] When in use, the foamed aluminum enters from the relatively higher side of the feed pipe 2, and is transported to the bottom of the feed pipe 2 by the conveying mechanism 20 in the feed pipe 2. The bottom of the feed pipe 2 is connected to the feed port 10 at the bottom of the cooling pool 1, that is, the foamed aluminum entering the feed pipe 2 will be transported to the bottom of the cooling pool 1 by the conveying mechanism 20. In this process, due to the principle of communicating vessels, the foamed aluminum will be immersed in the cooling water in the feed pipe 2 in advance for cooling treatment. After entering the cooling pool 1, the foamed aluminum will float in the cooling water because its density is less than that of water. During the floating process, the foamed aluminum will touch the multiple inclined plates 11 arranged on the inner wall of the cooling pool 1. Compared with the foamed aluminum floating in a straight line in the cooling water, the setting of the inclined plates 11 can delay the time for the foamed aluminum to float to the cooling water surface, which can also make the foamed aluminum have a longer contact time with the cooling water to achieve cooling treatment. After the foam aluminum floats to the cooling water surface, the conveying mechanism 20 on the side of the connection between the cooling pool 1 and the opening 30 of the box 3 continues to convey the foam aluminum that floats to the top of the cooling water to the inside of the box 3, and continues the second cooling process. The foam aluminum that enters the box 3 will fall on the conveying mechanism 20 located in the box 3, and the conveying mechanism 20 in the box 3 will continue to convey the foam aluminum. At this time, the foam aluminum will contact the coating component on the top of the box 3. The coating component will apply water to the surface of the foam aluminum, so that a thin layer of water film is formed on the surface of the foam aluminum, and then the heat on the foam aluminum is driven by the evaporation of the water film to complete the cooling process of the foam aluminum.

[0038] Further, such as Figure 1and Figure 4 As shown, the conveying mechanism 20 is a belt conveying mechanism 20 , and a baffle 21 with an L-shaped cross section is vertically arranged on the belt used for conveying, and a water leakage hole 22 is opened on the baffle 21 .

[0039] The conveying mechanism 20 is a belt conveying mechanism 20, and the baffle 21 is arranged on the conveying belt. A part of the baffle 21 in the L-shaped baffle 21 is arranged along the length direction, and the other part of the baffle 21 is used to resist the foam aluminum.

[0040] When in use, the L-shaped baffle 21 arranged on the conveyor belt can hold up the foam aluminum to prevent it from entering the bottom of the cooling water when being transported in the feed pipe 2 because its own density is less than that of water; when being transported at the top of the cooling pool 1, it prevents the foam aluminum from sliding from the inclined belt into the water; and when being transported inside the box 3, it prevents relative displacement between the foam aluminum and the conveying mechanism 20 when the coating component is coating the surface of the foam aluminum. The through holes opened on the baffle 21 are convenient for filtering out cooling water when transporting the foam aluminum in the feed pipe 2 and the top of the cooling pool 1 respectively, so as to avoid accumulation and blockage of cooling water.

[0041] Further, such as Figure 3 As shown, a heat exchanger 12 with a liquid inlet and a liquid outlet is provided on the outer wall of the cooling pool 1, the liquid inlet of the heat exchanger 12 is connected to a liquid inlet pipe 13 extending to the interior of the cooling pool 1, the liquid inlet pipe 13 is provided with a water pump 15, and the liquid outlet of the heat exchanger 12 is connected to a liquid outlet extending to the interior of the cooling pool 1.

[0042] When in use, the heat exchanger 12 is arranged on the outer wall of the cooling pool 1, and is connected with the cooling water in the cooling pool 1 through the liquid inlet and the liquid outlet. Since the cooling water in the cooling pool 1 is in contact with the foam aluminum for a long time, the temperature of the cooling water will gradually increase. Therefore, the heat exchanger 12 can perform heat exchange treatment on the cooling water in the cooling pool 1, and finally pass the cooling water with a lower temperature after the heat exchange treatment into the cooling pool 1 to prevent the cooling water temperature from rising and being unfavorable to the cooling of the foam aluminum.

[0043] Further, such as Figure 1 and Figure 2 As shown, the coating assembly includes a fixed rod 32, a fixed block 33 and a brush 37. The fixed rod 32 is vertically arranged on the inner top of the box body 3, the fixed block 33 is arranged on the free end of the fixed rod 32, the brush 37 is arranged at the bottom of the fixed block 33, a liquid storage chamber 34 is opened inside the fixed block 33, a water inlet 35 is opened on the side wall of the fixed block 33, a water outlet 36 is opened at the bottom of the fixed block 33, and a water pipe 38 connected with the water inlet 35 is penetrated through the side wall of the box body 3.

[0044] The distance between the brush 37 on the fixed block 33 and the conveying mechanism 20 is sufficient for the foam aluminum to pass through, and the brush 37 will be squeezed after touching the foam aluminum, causing the brush 37 to bend and deform. The water outlet 36 on the fixed block 33 has a small diameter, which is convenient for forming a water film on the foam aluminum. If the water output is too large, it will make it difficult to form a water film and waste water resources. A driving mechanism is set on the side wall of the box body 3 to drive the conveying mechanism 20 inside the box body 3 to operate.

[0045] When in use, the conveying mechanism 20 conveys the foam aluminum that falls from the opening 30 of the box body 3. During the conveying, the foam aluminum will contact the brush 37 on the fixed block 33 and squeeze the brush 37. The water pipe 38 releases water and enters the liquid storage chamber 34 in the fixed block 33 through the water inlet 35 on the fixed block 33, and then flows out through the water outlet 36 opened on the fixed block 33. The water flowing out from the water outlet 36 will flow through the brush 37 to the foam aluminum and form a water film.

[0046] Further, such as Figure 2 As shown, a reset ball valve 39 with a handle is provided on the water pipe 38 , and the handle of the reset ball valve 39 is in periodic sliding contact with the baffle 21 in the conveying mechanism 20 located in the box body 3 .

[0047] The ball valve can control the drainage of the water pipe 38, the reset ball valve 39 can automatically reset the switch, and the reset ball valve 39 with a handle can make the handle and the baffle 21 contact periodically, so that when the conveying mechanism 20 in the box body 3 conveys the foam aluminum, the baffle 21 is in periodic contact with the reset ball valve 39 with a handle, so that the water pipe 38 is opened to drain water only when a water film is needed, and it is automatically reset and closed when not in use, thereby avoiding waste of water resources.

[0048] Further, such as Figure 1 As shown, a drying box 4 is provided on the outer side wall of the box body 3 and is connected thereto, and is used for drying the foamed aluminum.

[0049] When in use, the drying box 4 connected to the outer wall of the other side of the box body 3 is used to dry the foam aluminum to avoid too much residual moisture accumulating on the foam aluminum, which makes it inconvenient to transport and store.

[0050] Further, such as Figure 1 As shown, the inner bottom of the box body 3 is provided with an inclined surface inclined toward one side of the cooling pool 1 .

[0051] When in use, the bottom of the box body 3 is an inclined surface, which can collect the water dropped when the coating component applies the water film to one side, avoiding the waste of water resources caused by the weak fluidity of the residual water in the box body 3.

[0052] Further, such as Figure 1As shown, a liquid inlet channel 16 extending to the interior of the cooling pool 1 is provided on the side wall of the box body 3 , and the liquid inlet channel 16 is connected to a relatively lower side of the inner bottom of the box body 3 .

[0053] When in use, the liquid inlet channel 16 is located at the position where the inner bottom of the box body 3 is connected to the cooling pool 1, and can collect the water that falls to the bottom of the box body 3 and transport it to the cooling pool 1, thereby realizing the recycling of resources.

[0054] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. In the absence of conflicts, the embodiments of the present application and the features in the embodiments may be arbitrarily combined with each other.
