Description

Technical Field

[0001] This utility model relates to the technical field of aluminum liquid vortex well systems, and in particular to an aluminum liquid conveying filling block. Background Technology

[0002] The aluminum vortex well system is a key component of a double-chamber aluminum furnace or a recycled aluminum smelting furnace. It is mainly used for the efficient and low-loss melting of aluminum scraps and other waste aluminum. Its core principle is to use the high-speed flow of molten aluminum to form a vortex, which allows the waste aluminum to be quickly immersed into the molten pool, reducing oxidation loss.

[0003] Generally, an aluminum molten metal vortex well system includes a drive unit, an impeller shaft, a pump chamber block, and a vortex well chamber block. However, existing aluminum molten metal vortex well systems often use separate pump chamber blocks and vortex well chamber blocks outside the smelting furnace to circulate and transport the aluminum molten metal. This results in a non-compact structure, excessively long flow channels, and is not conducive to increasing the aluminum molten metal flow rate. If the pump chamber block and vortex well chamber block are assembled together, it will be beneficial to shorten the flow channel and increase the aluminum molten metal flow rate. However, the pump chamber block and vortex well chamber block differ significantly in size, therefore, it is necessary to develop a filler block with a flow channel for assembly. Utility Model Content

[0004] The purpose of this invention is to provide an aluminum liquid conveying filling block, which, together with the pump chamber block and the vortex well chamber block, forms a rectangular block that provides stable support for the aluminum liquid vortex well system.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model relates to an aluminum liquid conveying filling block, which is assembled with a pump chamber block and a vortex well chamber block. It includes a filling block body, which is a rectangular refractory material block. The height of the filling block body is the same as that of the pump chamber block and the vortex well chamber block. The length of the filling block body is the same as the width of the pump chamber block, and the length of the vortex well chamber block is equal to the length of the pump chamber block plus the width of the filling block body. A flow channel connecting the dual-chamber furnace and the pump chamber block is provided at the bottom of the filling block body.

[0007] Furthermore, the flow channel is a square channel bent at a right angle at the bottom of the filler block body, the flow channel port is set as a liquid supply hole on the narrow side wall of the filler block body, and the flow channel port is set as a liquid outlet on the large side wall of the filler block body; an exhaust hole is provided on the top surface of the filler block body, and the bottom end of the exhaust hole is connected to the flow channel.

[0008] Furthermore, it also includes a grid block, with a grid mounting groove provided around the liquid outlet, and the grid block installed in the grid mounting groove; the grid area of ​​the grid block can intercept scum from the molten aluminum passing through the liquid outlet.

[0009] Furthermore, the grid area of ​​the grid block includes a first grid area and a second grid area. After the grid block is flipped up and down, the first grid area and the second grid area can alternately cover the liquid outlet.

[0010] Furthermore, rectangular sealing grooves are provided around the periphery of the first and second grid areas, and the sealing grooves are filled with rock wool strips.

[0011] Furthermore, threaded holes for disassembly are provided at the four corners of the grid block.

[0012] Furthermore, the top surface of the filling block body is provided with lifting holes at the four corners.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] This practical aluminum molten metal conveying filler block, by setting the outer dimensions of the filler block body to match the dimensions of the pump chamber block and the vortex well chamber block, allows the three to be assembled into a regular rectangular block, shortening the flow channel while maintaining good structural stability. A flow channel connecting the dual-chamber furnace and the pump chamber block is provided at the bottom of the filler block body, enabling pre-pumping drainage of the pump chamber block and facilitating slag removal of the aluminum molten metal before pumping. This new aluminum molten metal conveying filler block, assembled together with the pump chamber block and the vortex well chamber block into a rectangular block, provides stable support for the aluminum molten metal vortex well system.

[0015] Furthermore, by adding vents, the gas in the flow channel can be effectively discharged, and the slag on the surface of the molten aluminum can be easily observed by operators. A grid mounting groove is opened around the outlet, and grid blocks are installed in the groove to intercept slag flowing out of the outlet, preventing brittle slag from entering the pump chamber and rubbing against the impeller, thus avoiding impeller wear. The grid blocks are composed of symmetrically arranged first and second grid areas. Even if the first grid area is severely worn by the molten aluminum, the second grid area can be flipped over to intercept slag, improving the service life of the grid blocks. Sealing grooves are opened around the first and second grid areas, and rock wool strips are installed, avoiding the use of refractory cement for sealing and facilitating disassembly during maintenance and repair. Lifting holes are added at the four corners of the top surface of the filler block body, facilitating the transfer and installation of the filler block body. Attached Figure Description

Detailed Implementation

[0022] The core of this utility model is to provide an aluminum liquid conveying filling block, which is assembled together with the pump chamber block and the vortex well chamber block into a rectangular block, providing stable support for the aluminum liquid vortex well system.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Refer to the attached diagram. Figure 1 This is a three-dimensional structural diagram of the aluminum liquid conveying filling block of this utility model in use; Figure 2 This is a three-dimensional structural diagram of the aluminum liquid conveying filler block of this utility model; Figure 3 This is a schematic diagram of the three-dimensional structure of the filling block of this utility model; Figure 4 This is a three-dimensional structural diagram of the grid block of this utility model.

[0026] In one specific implementation, such as Figures 1-4As shown, this utility model of aluminum liquid conveying filler block is applied in an aluminum liquid vortex well system, assembled together with pump chamber block 3 and vortex well chamber block 4. This utility model of aluminum liquid conveying filler block includes a filler block body 1, which is a rectangular refractory material block, specifically cast from silicon nitride material. The height of the filler block body 1 is the same as that of pump chamber block 3 and vortex well chamber block 4, the length of the filler block body 1 is the same as the width of pump chamber block 3, and the length of vortex well chamber block 4 is equal to the length of pump chamber block 3 plus the width of filler block body 1. That is, the dimensions of the filler block body 1, pump chamber block 3, and vortex well chamber block 4 are matched to ensure that the assembled block forms a rectangular prism shape. Furthermore, the three are assembled on-site and bonded together using refractory cement. The bottom of the filler block body 1 is provided with a flow channel connecting the double-chamber furnace and pump chamber block 3, which guides the aluminum liquid from the insulation zone of the double-chamber furnace to the pump chamber of pump chamber block 3 for lifting and conveying.

[0027] By matching the dimensions of the main body 1 of the filling block with those of the pump chamber block 3 and the vortex well chamber block 4, the three can be assembled into a regular rectangular block, shortening the flow channel while maintaining good structural stability. A flow channel connecting the dual-chamber furnace and the pump chamber block 3 is provided at the bottom of the main body 1, allowing for pre-pumping drainage of the pump chamber block 3 and facilitating slag removal of the molten aluminum before pumping. This aluminum molten aluminum conveying filling block, assembled together with the pump chamber block and the vortex well chamber block into a rectangular block, provides stable support for the aluminum molten aluminum vortex well system.

[0028] In one specific embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the flow channel is a right-angled bend at the bottom of the filler block body 1, and the cross-section of the channel is square. The flow channel port is configured as a liquid supply hole 103 on the narrow side wall of the filler block body 1, and as a liquid outlet 104 on the large side wall of the filler block body 1. An exhaust hole 102 is provided on the top surface of the filler block body 1, and the bottom end of the exhaust hole 102 is connected to the flow channel.

[0029] Specifically, such as Figure 1 and Figure 3 As shown, the liquid supply hole 103 is centered in the width direction of the filling block body 1, and the liquid outlet 104 is centered in the length direction of the filling block body 1. The vent hole 102 is centered on the top surface of the filling block body 1 and is vertically opened.

[0030] By adding an exhaust port 102, the gas in the flow channel can be effectively discharged, and it also makes it easier for operators to observe the slag on the surface of the molten aluminum.

[0031] In one specific embodiment of this utility model, such as Figures 2-4As shown, the aluminum liquid conveying filling block of this utility model also includes a grid block 2. A grid mounting groove 105 is provided around the outlet 104. Both the grid block 2 and the grid mounting groove 105 are rectangular in shape. The grid block 2 is directly embedded in the grid mounting groove 105. The grid area of ​​the grid block 2 can intercept scum from the aluminum liquid passing through the outlet 104.

[0032] Specifically, such as Figure 2 and Figure 4 As shown, the grid area is a structure of multiple parallel vertical strip holes spaced at equal intervals.

[0033] Specifically, such as Figure 2 and Figure 4 As shown, the grid area of ​​the grid block 2 includes a first grid area 201 and a second grid area 202. After the grid block 2 is flipped up and down, the first grid area 201 and the second grid area 202 can alternately cover the liquid outlet 104. The first grid area 201 and the second grid area 202 are of equal size and have the same structure.

[0034] Specifically, such as Figure 2 and Figure 4 As shown, rectangular sealing grooves 203 are formed around the periphery of the first grid area 201 and the second grid area 202. The sealing grooves 203 are filled with rock wool strips, and their cross-section is also rectangular. Sealing grooves 203 are provided on both large side surfaces of the grid block 2. The rock wool strips are pressed tightly between the grid block 2 and the side walls of the pump chamber block 3, and between the grid block 2 and the bottom surface of the grid mounting groove 105, forming a seal.

[0035] Specifically, such as Figure 2 and Figure 4 As shown, threaded holes 204 for disassembly are provided at the four corners of the grid block 2. Set screws are used to connect the threaded holes 204. The inner end of the set screw presses against the bottom surface of the grid mounting groove 105. By alternately and evenly screwing in the four set screws, the grid block 2 can be slowly pushed out of the grid mounting groove 105, completing the disassembly.

[0036] By creating a grid mounting groove 105 around the outlet 104, and installing grid blocks 2 within the groove 105, the molten aluminum flowing out of the outlet 104 is intercepted to prevent brittle scum from entering the pump chamber of the pump chamber block 3 and rubbing against the impeller, thus avoiding impeller wear. The grid blocks 2 are composed of symmetrically arranged first grid areas 201 and second grid areas 202. Even after the first grid area 201 is severely worn by the molten aluminum, it can be flipped over and the second grid area 202 can be used to intercept scum, thus improving the service life of the grid blocks 2. By creating sealing grooves 203 around the first grid area 201 and second grid area 202 and installing the rock wool strips, the use of refractory cement for sealing is avoided, facilitating disassembly during maintenance and repair.

[0037] In one specific embodiment of this utility model, such as Figures 1-3 As shown, the top surface of the filler block body 1 is provided with lifting holes 101 at the four corners. The lifting holes 101 are threaded holes, which can be used to install lifting rings.

[0038] By adding lifting holes 101 at the four corners of the top surface of the filling block body 1, it is convenient to transfer and install the filling block body 1.

[0039] The working process of this utility model aluminum liquid conveying filler block is as follows: The aluminum liquid conveyed from the insulation zone of the double-chamber furnace first enters the bottom flow channel of the filler block body 1 through the liquid supply hole 103. If the aluminum liquid contains gas, the gas can be discharged from the exhaust hole 102. When the aluminum liquid flows out from the liquid outlet 104, it needs to pass through the vertical bars of the first grid area 201 and the second grid area 202, where scum is intercepted. The aluminum liquid conveyed from the insulation zone is generally relatively clean with less scum. After long-term operation, it is found that the flow rate of aluminum liquid entering the pump chamber of the pump chamber block 3 gradually decreases. At the same time, when the operator observes from the exhaust hole 102 that the flow channel is severely blocked by scum, it is necessary to disassemble the filler block body 1 for inspection and maintenance. During inspection and maintenance, it is necessary to first stop the aluminum liquid pumping, shut off the plug rod of the aluminum liquid flow channel, and drain the residual aluminum liquid. Carefully pry open the refractory cement surface of the filler block body 1 from the pump chamber block 3 and the vortex well chamber block 4 with a cutter, and install the lifting ring onto the lifting hole 101. Using an overhead crane, lift the main body 1 of the filler block from the combined block to the maintenance site, and disassemble the grid block 2. Connect the threaded hole 204 with a set screw, ensuring the inner end of the set screw is pressed against the bottom surface of the grid mounting groove 105. Alternately and evenly screw in the four set screws to slowly push the grid block 2 out of the grid mounting groove 105, completing the disassembly of the grid block 2. Remove any remaining scum and impurities from the two ports, the supply port 103 and the outlet port 104. Observe the wear condition of the first grid area 201 of the grid block 2. If the vertical bars are severely worn and widened, the second grid area 202 needs to be flipped and swapped to the outlet port 104 position and reinstalled. Observe whether the rock wool strips in the sealing groove 203 are damaged; if damaged, they need to be replaced. Reapply refractory cement to the bonding surface of the main body 1 of the filler block. After hoisting into place and curing, it can be put back into operation.

[0040] In summary, this utility model of an aluminum molten metal conveying filler block, by setting the external dimensions of the filler block body 1 to match the dimensions of the pump chamber block 3 and the vortex well chamber block 4, allows the three to be assembled into a regular rectangular block, shortening the flow channel while maintaining good structural stability. The flow channel at the bottom of the filler block body 1, connecting the dual-chamber furnace and the pump chamber block 3, allows for pre-pumping drainage of the pump chamber block 3, facilitating aluminum molten metal slag removal before pumping. This utility model of an aluminum molten metal conveying filler block, assembled together with the pump chamber block and the vortex well chamber block into a rectangular block, provides stable support for the aluminum molten metal vortex well system. Furthermore, the addition of an exhaust port 102 effectively discharges gas from the flow channel and also facilitates observation of slag on the surface of the aluminum molten metal by operators. By creating a grid mounting groove 105 around the outlet 104, and installing grid blocks 2 within the groove 105, the molten aluminum flowing out of the outlet 104 is intercepted to prevent brittle scum from entering the pump chamber of the pump chamber block 3 and rubbing against the impeller, thus avoiding impeller wear. The grid area of ​​the grid block 2 is composed of a first grid area 201 and a second grid area 202 arranged symmetrically. After the first grid area 201 is severely worn by the molten aluminum, it can be flipped over and the second grid area 202 can be used to intercept scum, thus improving the service life of the grid block 2. By creating sealing grooves 203 around the first grid area 201 and the second grid area 202 and installing the rock wool strips, the use of refractory cement for sealing is avoided, facilitating disassembly during maintenance and repair. By adding lifting holes 101 at the four corners of the top surface of the filling block body 1, the transfer and installation of the filling block body 1 are facilitated.
