[0001] The invention relates to the technical field of aluminum alloy heat treatment, in particular to an aluminum rod cooling chamber. Background Art
[0002] The aluminum rod is heated to about 550°C in the homogenizing furnace and kept warm for a certain period of time, then quickly taken out of the furnace and quickly entered into the cooling chamber for cooling. The aluminum rod cooling chamber (or "aluminum rod cooling furnace" and other names) in the prior art is generally designed to supply air from the bottom and the top. Such a scheme has the following technical problems in actual production: the air flow direction in the furnace is fixed, and "dead corners" are prone to appear in the furnace. If a part of the aluminum rod is located at the "dead corner", the aluminum rod cannot be cooled evenly, and the internal structure of the aluminum rod is uneven, which affects the quality of the aluminum rod. In addition, the aluminum rod cooling chamber in the prior art uses a water curtain for spraying, which has a poor cooling effect and results in a long cooling time for the aluminum rod. In view of the above technical problems, the present application proposes a new aluminum rod cooling chamber that can avoid the "dead corners" in the furnace and can greatly improve the cooling speed and cooling effect. Summary of the invention
[0003] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide an aluminum rod cooling chamber, aiming to solve the technical problems in the prior art that the aluminum rod cooling chamber has "dead corners" during operation and the cooling speed is average.
[0004] In order to achieve the above object, the present invention adopts the following technical solutions: An aluminum rod cooling chamber comprises a furnace body, a furnace door and a spray device, wherein a first blower and an air outlet are arranged on the top of the furnace body, and a plurality of second blowers are arranged on both sides of the furnace body; the spray device comprises a water pump, and an outlet pipe of the water pump is connected with a plurality of horizontal spray pipes and a plurality of vertical spray pipes, each horizontal spray pipe is respectively provided with a plurality of first nozzles, and each vertical spray pipe is respectively provided with a plurality of second nozzles.
[0005] Furthermore, in the aluminum rod cooling chamber, the first nozzles on each horizontal spray pipe are arranged at equal intervals along the length direction of the horizontal spray pipe; and the second nozzles on each vertical spray pipe are arranged at equal intervals along the height direction.
[0006] Furthermore, in the aluminum rod cooling chamber, each first nozzle and each second nozzle have the same specifications.
[0007] Furthermore, in the aluminum rod cooling chamber, each first nozzle is arranged vertically downward; and each second nozzle is arranged horizontally.
[0008] Furthermore, in the aluminum rod cooling chamber, the first nozzles on any two adjacent horizontal spray pipes are staggered; and the second nozzles on any two adjacent vertical spray pipes are staggered.
[0009] Furthermore, in the aluminum rod cooling chamber, the outlet pipe of each first blower extends downward into the furnace body and is respectively connected to a guide assembly, and each guide assembly includes a shell, which is connected to the outlet pipe of the first blower; a plurality of guide plates are arranged in the shell, and an air outlet is respectively arranged at the end of each guide plate on the side of the shell facing the furnace body.
[0010] Furthermore, in the aluminum rod cooling chamber, each second blower is arranged at equal intervals.
[0011] Furthermore, in the aluminum rod cooling chamber, the number of second blowers on both sides of the furnace body is the same and is arranged one-to-one.

[0028] The present invention provides an aluminum rod cooling chamber. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0029] See also Figures 1 to 13 The present invention provides an aluminum rod cooling chamber. The attached drawings are only used to explain the structural principle and are not proportional to the actual product. The attached drawings only depict the structures related to the invention of this application, and some conventional structures are not specifically depicted. In order to facilitate observation of the internal structure, Figure 2 and Figure 4 The door panels and other structures are not drawn. In order to illustrate the relative relationship between the sprinkler pipe and the aluminum rod, Figure 1 and Figure 4 An aluminum rod is depicted (but the aluminum rod itself is not within the scope of protection of this application). Fig.13 The arrows in the figure indicate the direction of air flow.
[0030] The terms "first", "second", etc. described herein are merely different names for similar structures for the convenience of explanation and are not intended to limit the present application. For the convenience of explanation, some directional terms are inevitably used herein, but these directional terms are not intended to limit the present application, because they can be set to different directions in actual applications.
[0031] First see Figures 1 to 9The aluminum rod cooling chamber includes a furnace body 1, a furnace door 11 and a spraying device. A first blower 21 and an air outlet 19 are arranged on the top of the furnace body, and a plurality of second blowers 22 are arranged on both sides of the furnace body; the spraying device includes a water pump 4, and the outlet pipe 41 of the water pump is connected to a plurality of horizontal spray pipes 61 and a plurality of vertical spray pipes 62, each horizontal spray pipe is respectively provided with a plurality of first nozzles 71, and each vertical spray pipe is respectively provided with a plurality of second nozzles 72. The above-mentioned "blowers" are used to blow air into the furnace body. Compared with the prior art, the technical solution provided by this application does not have an exhaust fan.
[0032] It should be noted that the above-mentioned "horizontal spray pipe" and "vertical spray pipe" are named only according to the general shape of the two spray pipes for easy distinction. In actual application, it is not required that the "vertical spray pipe" must be absolutely perpendicular to the horizontal plane at 90°, nor is it required that the "horizontal spray pipe" must be absolutely parallel to the horizontal plane. The above-mentioned "several" refers to an indefinite number greater than or equal to 1, because the horizontal spray pipe and the several vertical spray pipes themselves are not the invention points of this application, and in actual application, their specific number varies with the size of the furnace body, so no specific limitation is made.
[0033] As a preferred option, the outlet pipe 41 of the water pump 4 is connected to two branch pipes 52 after extending into the furnace body, and the two branch pipes 52 are respectively arranged on both sides of the furnace body. Each vertical spray pipe 62 is respectively connected to the branch pipe 52 on the same side, and both ends of each horizontal spray pipe 61 are respectively connected to the corresponding branch pipe 52 (i.e., the horizontal spray pipe is arranged between the two branch pipes). This arrangement enables the vertical spray pipes to be arranged on both sides of the furnace body without interfering with the aluminum rod, and the water delivered by the water pump can be evenly delivered to each vertical spray pipe and horizontal spray pipe, ensuring that the amount of water sprayed by each nozzle is basically the same.
[0034] like Figure 7 and Figure 8 As shown, further, two water pumps 4 are provided, and the outlet pipe 41 of each water pump is connected to two branch pipes 52. Specifically, it can be achieved by the following method: the inlet ends of the two branch pipes are connected to a transverse branch pipe 51, and the outlet pipe 41 of each water pump is respectively connected to the transverse branch pipe 51, so that each water pump can normally deliver water to the branch pipe and spray it from each nozzle. By providing two water pumps, the spraying amount can be increased, and one water pump can also be in a standby state to ensure that the spraying can always be carried out normally.
[0035] Preferably, a filter 49 is provided on the outlet pipe of each water pump to prevent the impurities that may exist in the water from clogging the nozzle.
[0036] like Figure 8 and Fig.10As shown, each horizontal spray pipe 61 is arranged at equal intervals. Fig.11 As shown, the vertical spray pipes 62 on the same side are arranged at equal intervals, and the vertical spray pipes on both sides are arranged at the same intervals. Since the horizontal spray pipes have the same intervals, the vertical spray pipes have the same intervals, so the aluminum bars in the furnace can be sprayed evenly.
[0037] Furthermore, the first nozzles on each horizontal spray pipe are arranged at equal intervals along the length direction of the horizontal spray pipe; the second nozzles on each vertical spray pipe are arranged at equal intervals along the height direction. This arrangement further limits the arrangement of each nozzle, so that in the same spray pipe, each nozzle is evenly arranged, thereby further ensuring that the aluminum rods in the furnace are evenly sprayed.
[0038] Preferably, each spray pipe has the same specification, and each first nozzle and second nozzle have the same specification. Since the nozzles have the same specifications, interchangeability is improved and the water mist sprayed by each nozzle is ensured to be the same in size, so that the spray effect at each location in the furnace is the same.
[0039] Preferably, if Figure 4 and Fig. 9 As shown, each first nozzle is arranged vertically downward, and each second nozzle is arranged horizontally. This arrangement enables the spray of each nozzle to be directly aimed at the aluminum rod in the furnace, thereby improving the cooling effect.
[0040] See also Fig.10 and Fig.11 Preferably, the first nozzles 71 on any two adjacent horizontal spray pipes are staggered; the second nozzles 72 on any two adjacent vertical spray pipes are staggered. The above staggered arrangement can make the water mist sprayed by the first nozzle and the second nozzle cover a larger and more uniform area, further improving the cooling effect.
[0041] Preferably, each second blower is arranged at equal intervals. When the number of the first blower is 1, it is in the middle of the furnace roof in the width direction; when the number of the first blower is 2, they are symmetrically arranged on the furnace roof with the width direction as the symmetry axis. The advantage of this arrangement is that the air in the furnace is blown evenly, and the water mist will flow with the air flow, so the water mist will also be blown away evenly, thereby ensuring that the aluminum rods in the furnace are evenly cooled. Of course, according to actual conditions, the number of first blowers may be greater than 2.
[0042] See also Figure 2 , 4, 12 and 13, further, the outlet pipe 211 of each first blower 21 extends downward into the furnace body and is respectively connected to a guide assembly, each guide assembly comprises a shell 3, the shell is connected to the outlet pipe of the first blower; a plurality of guide plates 32 are arranged in the shell, and an air outlet 302 is respectively arranged at the end of each guide plate corresponding to the side of the shell facing the furnace body; this arrangement makes the air volume discharged from each air outlet roughly equal, so that the air delivered by the first blower is evenly distributed along the length direction in the furnace body.
[0043] Preferably, the housing 3 is rectangular, including a box body 30, and a cover plate 31 detachably arranged on the top of the box body 30, the cover plate 31 is provided with an air inlet 301 for connecting with the outlet duct 211 of the first blower. Each guide plate 32 includes a straight plate 321 and an arc plate 321, for guiding the airflow to the air outlet 302.
[0044] Preferably, the number of second fans 22 on both sides of the furnace body is the same and they are arranged one by one. This arrangement further ensures that the outside air enters the furnace evenly.
[0045] Preferably, the second blowers 22 are installed at the same height. Since the second blowers on both sides of the furnace body are installed at the same height, the outside air enters the furnace from both sides of the furnace body and follows basically the same trajectory, so that the aluminum bars on both sides of the furnace are evenly cooled.
[0046] Preferably, each second blower is installed at the bottom of both sides of the furnace body, and each second blower is located below the guide assembly. This makes the air outlet 302 of the guide assembly located above the air outlet of the second blower (corresponding to the position of the shutter 221), so that the air outlet of the first blower and the air outlet of the second blower will not interfere with each other, and can cover a larger range in the vertical direction.
[0047] Furthermore, if Figure 2 and Figure 6 As shown, the outlet side (ie, the side facing the furnace body) of each second blower is respectively provided with a shutter 221 to facilitate the adjustment of wind direction and to prevent small animals and foreign objects from entering the furnace body.
[0048] Preferably, the first blower is close to the furnace door, and the air outlet is far away from the furnace door. Figure 5 It can be observed that, in the top view, the first blower is located in the front half of the top of the furnace body, and the air outlet is arranged in the rear half of the top of the furnace body. This arrangement makes the distance between the first blower and the air outlet as large as possible, and the air delivered by the first blower can travel a longer distance in the furnace body before leaving from the air outlet.
[0049] It can also be observed from the attached figure that the second blowers are distributed along the length direction of the furnace body, the second blowers are arranged below the first blowers, and the blowers are also arranged below the air outlet. Such an arrangement enables the air outlets of multiple second blowers to cover a wider range, and the airflow is fully circulated in the furnace, which can evenly and quickly take away the heat of the aluminum bars.
[0050] like Figure 4 and Figure 6 As shown, two support frames 81 and at least one slide rail 82 are arranged in parallel on the bottom plate of the furnace body, and each support frame and slide rail are arranged in parallel (i.e., parallel to the length direction of the furnace body). This arrangement is convenient for loading aluminum bars. In practical applications, the aluminum bars to be processed are placed on a slide seat, and a slide groove is arranged at the bottom of the slide seat to connect with the slide rail, so that the aluminum bars to be processed can be conveniently fed into the furnace body.
[0051] In actual applications, the water inlet pipe of the above-mentioned spray device is connected to the factory water source, and a water pump and a regulating valve are arranged on the water inlet pipe. The regulating valve is used to adjust the water flow rate, thereby controlling the size of the spray.
[0052] When in use, put the aluminum rod to be cooled into the furnace and close the furnace door. Turn on the water pump and regulating valve, turn on the first blower and the second blower, and the outside air enters the furnace to blow away the spray and take away the heat of the aluminum rod, thereby achieving the effect of cooling the aluminum rod. In practical applications, the aluminum rod cooling chamber provided by this application can cool the aluminum rod at 500-600°C to room temperature within one hour, greatly improving the cooling speed.
[0053] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all these changes or substitutions should fall within the protection scope of the present invention.
