Description

Technical Field

[0001] The utility model relates to the technical field of liquid aluminum conveying equipment, in particular to a pure liquid aluminum conveying trough. Background Art

[0002] When recycling recycled aluminum, the scrap aluminum that has been initially freed of mud and sand impurities is usually placed in a smelting furnace and heated to 700 degrees Celsius. The scrap aluminum becomes liquid aluminum, and a small amount of heavier impurities fall to the bottom, while most of the lighter impurities are suspended on the surface of the liquid aluminum. The liquid aluminum containing suspended matter is discharged through the impurity discharge port to a designated device for solid-liquid separation. The impurity discharge port is closed, and the liquid aluminum outlet of the smelting furnace is opened through a sealing device to discharge the liquid aluminum into subsequent molds.

[0003] Currently, after the liquid aluminum is transported, the existing liquid aluminum conveyor troughs need to be cleaned of impurities and residues, as well as maintained. In order to reduce heat loss during the liquid aluminum transportation, most conveyor troughs are equipped with insulation covers on the top.

[0004] However, right after the conveying is completed, if the internal temperature is allowed to drop completely, the impurities and residual liquid aluminum inside will easily solidify, increasing the difficulty of cleaning. If the internal temperature has not dropped completely before operation, a large amount of heat will surge out when the insulation cover is just opened, which may easily cause certain harm to the staff and pose a safety hazard. For this reason, we propose to design a pure liquid aluminum conveying trough. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.

[0022] Secondly, the present application is described in detail in combination with the schematic view. In order to facilitate the description, the sectional view of the device structure will be partially enlarged without the general proportion, and the schematic view is only an example, which should not limit the scope of protection of the present application. In addition, the three-dimensional spatial dimensions of length, width and depth should be included in the actual manufacture.

[0023] In order to make the purposes, technical schemes and advantages of the present application more clear, the embodiments of the present application will be described in further detail below with reference to the drawings.

[0024] Please refer to Figure 1-3 The present application provides a kind of pure liquid aluminum conveying groove, including conveying groove 1 and blanking groove 2, conveying groove 1 end and blanking groove 2 inside are connected, conveying groove 1 and blanking groove 2 inner top are inclined downward from conveying groove 1 to blanking groove 2, compared with traditional flat bottom conveying groove, more convenient for liquid aluminum to flow blanking.

[0025] A discharge port 3 is provided on one side of the outer wall of the feeding trough 2, and a partition 4 is provided in the middle of the feeding trough 2. A through-hole 401 is provided in the middle of the partition 4, located near the bottom of the partition 4. This hole 401 facilitates the diversion and discharge of liquid aluminum that has just entered the feeding trough 2 from the transport trough 1. The opening height of the through-hole 401 can block some of the residual lighter impurities floating on the top of the liquid aluminum, while the bottom can also block some of the residual heavier impurities that sink to the bottom of the liquid aluminum, thus providing terminal filtration.

[0026] Discharge pipes are provided at both ends of the bottom of the feed chute 2 and are located on both sides of the partition 4, so as to completely discharge the liquid aluminum in the feed chute 2 and prevent the internal residue from solidifying when the conveying chute is not in use.

[0027] A heat-insulating cover 5 is provided on the top of the transport trough 1 , observation ports 6 are provided on both sides of the heat-insulating cover 5 , and movable doors 7 are provided outside the observation ports 6 .

[0028] In this embodiment, a high-temperature resistant glass 601 is fixedly connected to one side of the observation port 6 close to the center of the transport trough 1. The high-temperature resistant glass 601 is arranged to be concave toward the middle of the transport trough 1, so as to block the hot air released by the liquid aluminum at the top of the transport trough 1 and facilitate the staff to open the movable door 7 at the observation port 6 to observe the transport trough 1.

[0029] An insulation cover 8 is provided on the top of the discharge chute 2, and the sides of the transport chute 1 and the insulation cover 5 are fixed by bolts. The sides of the discharge chute 2 and the insulation cover 8 are fixed by bolts, which facilitates the fixation between the transport chute 1 and the insulation shell on the top of the discharge chute 2.

[0030] An inspection box 9 is fixedly connected to the top of the insulation cover 8, and an inspection door 10 is provided on the side of the inspection box 9 away from the transport trough 1. The top of the inspection door 10 is fixedly connected to an air intake bin 11, and a pump body 12 is fixedly connected to one side of the outer wall of the air intake bin 11, and an air pipe 13 is fixedly connected to the exhaust end of the pump body 12.

[0031] The bottom of the air inlet bin 11 is connected to the top of the inspection door 10, and the nozzle at the bottom end of the air pipe 13 is facing the top of the discharge port 3, so that the hot air discharged from the air inlet bin 11 is blown to the discharge port 3, so as to ensure the temperature of the liquid aluminum when it is discharged from the discharge port 3 and prevent the liquid aluminum from solidifying.

[0032] During use, the liquid aluminum flows along the transport trough 1 to the discharge trough 2. As the liquid aluminum flows, the liquid level in the discharge trough 2 rises, and the liquid aluminum flows from the through hole 401 to the other side of the partition 4 and is discharged from the discharge port 3.

[0033] During the discharge process, the pump body 12 is started to pump the high-temperature gas in the discharge chute 2 upward into the air inlet bin 11 , so that the heated gas flows toward the discharge port 3 through the air pipe 13 .

[0034] During the specific processing process, in order to ensure the safety of the workers, protective covers should be installed around the discharge port 3 to prevent high-temperature gas from causing harm to the safety of the workers.

[0035] When the staff checks the transport chute 1 and the discharge chute 2, the movable door 7 can be opened. Since the observation port 6 is blocked by the high-temperature resistant glass 601, the overflow of high-temperature gas is effectively avoided, making it easier for the staff to intuitively control the discharge of liquid aluminum.

[0036] When the liquid aluminum is discharged, the inspection box 9 is set on the top of the discharge chute 2, and the pump body 12 can accelerate the discharge of the internal high-temperature gas, so that the equipment can be cooled down quickly and convenient for maintenance.

[0037] At the same time, since the pump body 12 extracts the gas, the air flow can move upward along the inspection box 9. When the staff opens the inspection door 10, the hot gas can be prevented from being ejected from the inspection door 10, thereby protecting the personal safety of the staff.

[0038] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
