Description

Technical Field

[0001] The present application relates to the technical field of gas heating and constant temperature technology, and specifically to an inert gas constant temperature device for a degasser. Background Art

[0002] A degasser is a device used to remove gas from liquids. It is mainly used for the purification of molten aluminum. During the production and processing of molten aluminum, it is inevitable that some impurities such as hydrogen and oxides will be contained in it. These impurities will affect the mechanical properties and surface quality of aluminum products. Therefore, a degasser is needed to separate the impurities in the molten aluminum.

[0003] When using a degasser to separate impurities from molten aluminum, inert gases (such as argon, nitrogen, etc.) are often required. Since the inert gas mixed with the molten aluminum needs to reach a certain temperature to achieve the best degassing effect, an inert gas constant temperature equipment is needed to heat and keep the inert gas warm.

[0004] Existing inert gas constant temperature equipment for degassing machines usually consists of a constant temperature box, in which a delivery pipe and a heating wire are installed. The heating wire is used to heat the delivery pipe and the inert gas in the delivery pipe at the same time. At the same time, a constant temperature water zone is also provided in the constant temperature box, and the inert gas in the delivery pipe is kept warm by the constant temperature water zone and the constant temperature box.

[0005] Although the above-mentioned device achieves heating and heat preservation of inert gas, since aluminum products are usually produced in batches, the amount of aluminum liquid processed by the degasser at one time will also be large, and the inert gas needs to wait for a certain period of time after entering the constant temperature equipment before it can reach the temperature required for production from room temperature. Therefore, the inert gas constant temperature equipment needs to heat enough inert gas at one time to meet production needs. For this reason, a large enough space is reserved in the constant temperature box to coil a long conveying pipe. When the space in the constant temperature box is large, the efficiency of the heating wire used for heating will decrease as the space increases. If the space in the constant temperature box is not adjusted, the cost of inert gas heating and heat preservation will be greatly increased.

DETAILED DESCRIPTION

[0032] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0034] Example 1: This example mainly introduces the basic structure and working principle of the inert gas constant temperature equipment for degassing machine, specifically:

[0035] like Figure 1-Figure 3 As shown, the present application provides an inert gas constant temperature device for a degasser, comprising a box 1, which is the main body of the constant temperature device. The heating and heat preservation of the inert gas are carried out in the box 1. An air inlet pipe 2 is fixedly installed at the bottom of one side of the box 1. One end of the air inlet pipe 2 extends into the box 1. The inert gas can enter the interior of the box 1 through the air inlet pipe 2.

[0036] A delivery pipe 3 is fixedly installed on one side of the air inlet pipe 2 extending into the box body 1. The delivery pipe 3 is coiled and installed in the box body 1, which saves space and makes the delivery pipe 3 as long as possible so as to store more inert gas. The delivery pipe 3 and the air inlet pipe 2 are of an integrated design. The inert gas can enter the delivery pipe 3 through the air inlet pipe 2 and then enter the box body 1. Moreover, due to the integrated design of the delivery pipe 3 and the air inlet pipe 2, the inert gas in the delivery pipe 3 will not overflow from the delivery pipe 3 and combine with the residual air in the box body 1, thereby affecting the purity of the inert gas.

[0037] Part of the delivery pipe 3 is coiled at the lower end of the box body 1, and the other part is coiled and installed at the upper end of the box body 1. For the convenience of explanation, the delivery pipe 3 coiled at the lower end is defined as the first pipe, and the delivery pipe 3 coiled at the upper end is positioned as the second pipe. In this embodiment, the first pipe and the second pipe are fixedly connected to the box body 1 by fixing parts such as clamps to ensure that they are coiled firmly.

[0038] Continue to refer Figure 3 An exhaust pipe 5 is fixedly installed at the upper end of one side of the box body 1. One side of the exhaust pipe 5 extends into the box body 1 and is connected to the second pipe. Thus, the inert gas entering through the intake pipe 2 will enter the first pipe, then enter the second pipe through the first pipe, and finally pass through the second pipe and be discharged from the exhaust pipe 5 to be used for the degassing machine to process the aluminum liquid. Solenoid valves are provided in the exhaust pipe 5 and the intake pipe 2 to realize the closing or unblocking of the delivery pipe 3.

[0039] In order to achieve heating and constant temperature of the inert gas in the delivery pipe 3, a water immersion area (not shown in the figure) is provided at the lower end of the box body 1. The first pipe is located in the water immersion area. The water immersion area is used to store constant temperature water to heat the first pipe. Heaters 4 are also fixedly installed on both sides of the lower end of the box body 1. The heater 4 is provided with a heating end, which is located in the water immersion area. It should be noted that a water valve (not shown in the figure) is fixedly installed on the back of the box body 1 to facilitate the staff to inject constant temperature water into the box body 1.

[0040] Before the inert gas enters the delivery pipe 3, the staff can inject normal temperature water into the box 1 through the water valve, and then turn on the heater 4 to heat the constant temperature water. As the temperature of the constant temperature water increases, the temperature of the first pipe also increases, and at the same time, the inert gas in the delivery pipe 3 is heated. When the temperature of the inert gas used by the degasser does not need to be very high, the inert gas can be heated by the constant temperature water. When there are certain requirements for the temperature of the inert gas to be used, the inert gas needs to be further heated.

[0041] like Figure 3-Figure 4 As shown, a fixing plate (not shown) is fixedly installed at the upper end of the interior of the box 1, and a heating box 6 is fixedly installed at the bottom of the fixing plate. A heating wire is installed on the side of the bottom of the heating box 6 close to the second pipe. The heating wire is turned on or off by an electric control. When the heating wire is turned on, it will emit heat, thereby increasing the temperature inside the box 1. Since the second pipe is close to the heating box 6, the temperature of the inert gas in the second pipe will be increased more quickly.

[0042] Therefore, when a higher temperature inert gas is needed, the staff only needs to turn on the heating wire, and the heating wire emits heat to further increase the temperature in the box 1. Figure 3-Figure 4 At least two sets of fans 11 are fixedly installed on the top of the box body 1. At the same time, through holes corresponding to the positions and numbers of the fans 11 are opened on the fixing plate. When heating the inert gas, an external protective cover (not shown in the figure) needs to be put on the periphery of the fan 11. The external protective cover is fixedly connected to the box body 1 through a fixing piece, thereby preventing the hot air inside the box body 1 from escaping from the through holes. After the inert gas heating work is completed, the staff only needs to remove the external protective cover and then start the fan 11 to quickly discharge the hot air in the box body 1 through the through holes.

[0043] like Figure 4 As shown, a pump 12 is fixedly installed on one side of the box body 1, and one end of the pump 12 extends into the immersion area, and a circulating water pipe 13 is fixedly installed on the other end of the pump 12, and the other end of the circulating water pipe 13 extends to the upper end of the box body 1 and forms a circulation end. At the same time, a spray assembly 10 is fixedly installed on both sides of the upper end of the box body 1, and one end of the spray assembly 10 is connected to the circulation end. The spray assembly 10 is provided with multiple groups of spray heads, which are located on the side of the second pipe. When the pump 12 is started, it is suitable for extracting constant temperature water from the immersion area and pouring it into the spray assembly 10, and finally sprayed to the second pipe by the spray head of the spray assembly 10. Therefore, when the temperature of the second pipe is high, the second pipe can be cooled by the spray assembly 10, and the constant temperature water used for cooling can be recycled;

[0044] In this embodiment, if Figure 9 As shown, the second pipe is placed in the box body 1 along the horizontal direction, and is oval when viewed from the side of the box body 1. Figure 9 The area occupied by the second pipe (based on the perspective in the figure) is larger than the area occupied by the left and right sides of the second pipe. At the same time, the spray assembly 10 is also installed on the front and back sides of the second pipe. Therefore, when the spray assembly 10 cools the second pipe, it can spray constant temperature water to the second pipe over a large area, thereby cooling the second pipe as quickly as possible in a short time.

[0045] It should be noted that the box body 1 generally has a larger distance in the height direction and a smaller distance in the thickness direction. Therefore, if the coiled second pipe needs to be set to the maximum length, it can only be extended in the vertical direction. Therefore, in this embodiment, the second pipe is set to be an ellipse with the long axis in the vertical direction. Of course, it can also be set to be a rectangle with the long side in the vertical direction. Compared with the circular or square arrangement, the coiled second pipe can have a longer length, which is conducive to the second pipe being fully heated or cooled in the box body 1.

[0046] Further, such as Figure 3-Figure 4 As shown, a temperature sensor (not shown) and a pressure sensor (not shown) are respectively installed on the air inlet pipe 2. The temperature sensor and pressure sensor are located outside the box 1 to monitor the temperature and pressure of the inert gas when it enters the box 1. A temperature sensor is also installed on one side of the box 1, with one end of the temperature sensor extending into the immersion area to measure the temperature of the constant-temperature water in the immersion area. At the same time, a temperature sensor and a pressure sensor are also installed on the exhaust pipe 5 to monitor the temperature and pressure of the inert gas when it leaves the box 1.

[0047] When it is necessary to heat and keep the inert gas warm, the worker first needs to install an external protective cover on the box body 1 through the fixing parts, and then the worker transports the inert gas to the delivery pipe 3 through the air inlet pipe 2. At the same time, the worker starts the heater 4, and the heater 4 heats the constant temperature water in the immersion area, thereby heating the first pipe. If the temperature of the inert gas in the delivery pipe 3 is not high enough after being heated by the constant temperature water, the worker can start the heating box 6 again to heat the second pipe through the heating wire. After being heated by the constant temperature water and the heating wire, the temperature of the inert gas meets the use requirements of the degasser.

[0048] During this process, if it is necessary to dissipate heat from the delivery pipe 3, the staff starts the pump 12, the pump 12 pumps the constant temperature water in the immersion area into the circulating water pipe 13, the circulating water pipe 13 delivers the constant temperature water to the spray assembly 10, and finally sprays the constant temperature water to the delivery pipe 3 through the spray head to dissipate heat from the delivery pipe 3. After the work is completed, when the heat in the box 1 needs to be removed, the staff can manually remove the external protective cover and then start the fan 11. The fan 11 sucks the hot air in the box 1 out through the through hole to achieve rapid removal of the hot air in the box 1.

[0049] However, due to the large space inside the box 1, the delivery pipe 3 is divided into two parts, the upper and lower parts. When the heating wire heats the second pipe, the heating efficiency will inevitably decrease due to space reasons. In order to solve this problem, Figure 3 As shown, a partition 7 is fixedly installed in the middle of the box body 1. The partition 7 divides the box body 1 into two spaces, upper and lower. For the convenience of explanation, the upper and lower spaces are defined as an upper space and a lower space respectively. The second pipe is located in the upper space, and the first pipe is located in the lower space.

[0050] When the heating wire heats the delivery pipe 3, due to the effect of the partition 7, the volume of the upper space is smaller than that of the box body 1. As a result, the heat source of the heating wire can be dissipated into the upper space more quickly and better heat preservation is achieved, so that the temperature of the second pipe will rise faster, and the temperature of the inert gas in the second pipe will also rise faster.

[0051] like Figure 3-Figure 4 、 Figure 9 As shown, a first outlet 71 is provided on the partition 7, and a second outlet 72 is provided at the bottom of the partition 7. The interior of the partition 7 is hollow and forms a hollow chamber. The first outlet 71 is connected to the hollow chamber and the second outlet 72. For the convenience of explanation, when the first outlet 71 is connected to the hollow chamber and the second outlet 72, the partition 7 is defined as being in an open state. At this time, the upper space is connected to the lower space, and the hot air between the upper space and the lower space is communicated. At the same time, the constant temperature water sprayed by the spray assembly 10 will flow through the partition 7 to the lower space.

[0052] A slide plate 73 is slidably mounted in the hollow chamber of the partition plate 7. Figure 9 Taking the perspective in the figure as the standard, in the initial state, the slide plate 73 is located on the side close to the back of the box body 1. When the slide plate 73 is subjected to an external force, the slide plate 73 is suitable for sliding toward the front of the box body 1. At least two sets of first springs 74 are fixedly installed at one end of the slide plate 73. The other side of the first spring 74 is fixedly connected to the inner wall of the hollow chamber. When the slide plate 73 slides in the hollow chamber, the first spring 74 is compressed. It should be noted that the area of ​​the slide plate 73 is larger than the area of ​​the first outlet 71 and the second outlet 72, and is suitable for completely covering them.

[0053] In the initial state, the slide plate 73 is located at the first outlet 71 and the second outlet 72. For the convenience of explanation, the state of the partition 7 at this time is defined as the closed state. At this time, since the first outlet 71 and the second outlet 72 on the partition 7 are covered and closed by the slide plate 73, the upper space and the lower space are not connected to each other under the action of the partition 7, which can improve the heating efficiency of the electric heating wire in the upper space. However, when the delivery pipe 3 needs to be cooled by constant temperature water, the constant temperature water entering the upper space will accumulate on the partition 7. The partition 7 needs to be adjusted to the open state to allow the constant temperature water to flow to the lower space.

[0054] To this end, electromagnets are installed on the slide 73 and the inner wall of the hollow chamber. The electromagnets attract each other with opposite charges. In the initial state, the electromagnet is in a de-energized state. The slide 73 is located at the first outlet 71 and the second outlet 72 under the action of the first spring 74, and the partition 7 is in a closed state. When the partition 7 needs to be opened, the staff only needs to control the electromagnet to energize the slide 73. Under the action of the electromagnet, the slide 73 slides in the direction away from the back of the box 1, and the first spring 74 is compressed. At this time, the first outlet 71 and the second outlet 72 are no longer restricted by the slide 73, and the partition 7 is in an open state. In this application, a PLC control system is provided outside the box 1 to facilitate the alternating opening or closing of the electrical components in the box 1.

[0055] In summary, the staff is suitable for controlling the electromagnet to lose power or gain power, so as to adjust the partition 7 from the initial closed state to the open state, thereby adjusting the connection state between the upper space and the lower space.

[0056] Second embodiment: The above embodiment controls the communication between the upper space and the lower space in the box body 1 by sliding the partition 7 and the slide plate 73, thereby achieving the separation of the space in the box body 1 and retaining its own circulation of constant temperature water. However, since the second pipe is fixed, the coiled position of the second pipe cannot be changed. When the heating wire heats the second pipe, due to its arrangement (described in detail in the first embodiment), the second pipe located at the bottom is far away from the heating wire and cannot be heated quickly.

[0057] In order to solve this problem, this embodiment improves the installation method of the second pipeline on the basis of the first embodiment. Specifically: Figure 3-Figure 7 As shown, a motor 8 is fixedly mounted on one side of the housing 1. The output end of the motor 8 extends into the housing 1 and is fixedly mounted with a main shaft 81. One side of the main shaft 81 is movably connected to the inner wall of the housing 1 via a bearing, so that the main shaft 81 is suitable for rotating in the housing 1 under the drive of the motor 8. It should be noted that in this embodiment, the second pipe is coiled and wound around the main shaft 81 and is not fixedly connected to the inner wall of the housing 1.

[0058] At least two sets of connecting components are fixedly installed at the bottom of the main shaft 81, and the other end of the connecting component is fixedly installed with an auxiliary shaft 82. Sliding grooves are provided on both sides of the inner wall of the box body 1. The sliding grooves are arranged in a circle with the main shaft 81 as the center. The two sides of the auxiliary shaft 82 are slidably installed in the sliding grooves, so that the auxiliary shaft 82 is suitable for circumferential movement with the main shaft 81 as the center. It should be noted that the other end of the second pipe is wound around the auxiliary shaft 82. When the main shaft 81 rotates under the drive of the motor 8, the connecting component rotates synchronously, so that the auxiliary shaft 82 rotates synchronously, and drives the second pipe wound around the main shaft 81 and the auxiliary shaft 82 to rotate synchronously, thereby changing the angular position of the second pipe.

[0059] In the initial state, refer to Figure 9 The second pipe is vertically wound around the main shaft 81 and the auxiliary shaft 82. At this time, the pump 12 and the spray assembly 10 are turned on, and the constant temperature water sprayed by the spray head will be sprayed on the front and back sides of the second pipe (with Figure 9 The second pipe is in contact with the heating wire, but if the second pipe does not need to be cooled but heated at this time, since the second pipe is placed along the horizontal direction, the top of the second pipe is close to the electric heating wire, but the pipe below the top cannot be heated in time. Therefore, the staff can start the motor 8 at this time. The motor 8 starts to drive the main shaft 81 to rotate. The rotation of the main shaft 81 drives the connecting component and the auxiliary shaft 82 to rotate. The rotation of the auxiliary shaft 82 drives the top of the second pipe to rotate synchronously. The bottom end of the second pipe starts to deflect from the initial position directly below the top of the second pipe and is staggered with the top of the second pipe. In this way, the heat source of the electric heating wire can be directly dissipated to the front of the second pipe, and the heating area of ​​the second pipe is wider.

[0060] It should be noted that in order to adapt to the change of the position of the second pipe, the second pipe is configured as a hose, and a foldable hose is integrally provided between the first pipe and the second pipe to accommodate the flipping of the second pipe;

[0061] In summary, the position of the second pipe can be flipped by driving the main shaft 81 and the auxiliary shaft 82 to rotate by the motor 8. When the delivery pipe 3 needs to be heated, the staff can start the motor 8 to drive the second pipe to flip. The front and rear sides of the second pipe (with Figure 9 The second pipe is flipped from a vertical state to a horizontal state, and then the heating wire is started. The heating surface of the second pipe is wider. If the second pipe needs to be cooled, the motor 8 can be started to drive the main shaft 81 and the auxiliary shaft 82 to rotate, and the second pipe is flipped back to the initial state. At this time, the pump 12 and the spray assembly 10 are started again, and the front and back sides of the second pipe can be sprayed with constant temperature water, so that the second pipe can be cooled more quickly.

[0062] Embodiment 3: In the above embodiment, the motor 8 drives the main shaft 81 and the auxiliary shaft 82 to drive the second pipe to flip. However, when spraying and cooling the second pipe, if the second pipe is long and coiled densely (the pipes are in contact with each other and wound around the main shaft 81 and the auxiliary shaft 82), when the spray assembly 10 sprays the second pipe again, the surface of the second pipe can be sprayed with constant temperature water, but the contact area between the pipes cannot be sprayed with constant temperature water, and the heat in this area is difficult to release.

[0063] In order to solve this problem, this embodiment improves the discharge method and deflection method of the second pipe on the basis of the above embodiment. Specifically: Figure 6-Figure 7As shown, in this embodiment, the discharge mode of the second pipe is changed to a staggered arrangement. At the same time, in the initial state, the bottom end of the second pipe is not wound around the auxiliary shaft 82, but is a certain distance away from the auxiliary shaft 82. Due to the characteristics of the second pipe as a hose, its bottom end forms an overhanging end, and the overhanging end has a first end 31 and a second end 32 arranged in a staggered manner. It should be noted that the first end 31 is closer to the partition 7, and the horizontal height of the second end 32 is higher than the horizontal height of the first end 31.

[0064] In order to adapt to the staggered arrangement of the second pipeline, the auxiliary shaft 82 is arranged in a wave-shaped staggered manner. Figure 7 The auxiliary shaft 82 is provided with wavy peaks and valleys. The peaks are continuously arranged, and the bottom of the peaks is lower than the bottom of the valleys. In this embodiment, the peaks are protruding ends 821, and their positions and number correspond to the first end 31, while the number and positions of the valleys correspond to the second end 32. In the initial state, the distance between the protruding ends 821 and the first end 31 is the same as the distance between the second end 32 and the peak valleys.

[0065] like Figure 4-Figure 5 As shown, in the second embodiment, only the sliding connection between the auxiliary shaft 82 and the inner wall of the box body 1 is described. In this embodiment, sliding plates 83 are rotatably installed on both sides of the auxiliary shaft 82. At the same time, arc-shaped grooves 14 are opened on both sides of the inner wall of the box body 1. The sliding plates 83 are slidably installed in the arc-shaped grooves 14. The two ends of the arc-shaped grooves 14 are respectively provided with a first stationary point 141 and a second stationary point 142. The horizontal position of the first stationary point 141 is lower than the horizontal position of the second stationary point 142. It should be noted that the arc-shaped grooves 14 in the embodiment are the sliding grooves in the second embodiment, which are used to limit the movement trajectory of the auxiliary shaft 82. When the auxiliary shaft 82 is subjected to external force, it is suitable for rotating with the sliding plate 83 as the center of the circle, but the sliding plate 83 remains stationary. However, when the main shaft 81 rotates, it will drive the auxiliary shaft 82 to move synchronously.

[0066] In the initial state, when the auxiliary shaft 82 is located directly below the main shaft 81, the sliding plate 83 is located at the first stationary point 141. When the second pipe needs to be heated, the main shaft 81 needs to drive the auxiliary shaft 82 to move to change the position of the second pipe. As a result, driven by the auxiliary shaft 82, the sliding plate 83 rotates in the arc groove 14 and finally slides to the second stationary point 142. It should be noted that the arc groove 14 is not arranged with the main shaft 81 as the center. The distance between the first stationary point 141 and the main shaft 81 is shorter than the distance between the second stationary point 142 and the main shaft 81. Therefore, when the sliding plate 83 is at the second stationary point 142, the auxiliary shaft 82 is farther away from the main shaft 81.

[0067] In order to adapt to this change, in this embodiment, reference Figure 7-Figure 8The connecting assembly between the auxiliary shaft 82 and the main shaft 81 is a telescopic assembly 9, which includes a shell 91 fixedly mounted on the bottom of the main shaft 81. The interior of the shell 91 is hollow, and a second spring 92 is fixedly mounted on the bottom of the main shaft 81. The second spring 92 is located in the chamber of the shell 91. At the same time, a limit chamber 95 is provided in the shell 91. The inner diameter of the limit chamber 95 is larger than the inner diameter of the shell 91 and forms a limit step. A limit portion 93 is slidably mounted in the limit chamber 95. The top end of the limit portion 93 is fixedly connected to the second spring 92. Due to the limitation of the limit step, the limit portion 93 can only slide in the limit chamber 95.

[0068] Continue to refer Figure 8 A connecting rod 94 is fixedly installed at one end of the limiting portion 93 away from the second spring 92. The outer diameter of the connecting rod 94 is adapted to the inner diameter of the housing 91, and the other end of the connecting rod 94 is fixedly connected to the top of the auxiliary shaft 82. In the initial state, when the auxiliary shaft 82 is located directly below the main shaft 81, the sliding plate 83 is located at the first stationary point 141. At this time, the second spring 92 is in a normal state, and the limiting portion 93 is close to the main shaft 81. When the second pipe needs to be heated by the heating wire, the auxiliary shaft 82 is located directly below the main shaft 81. The shaft 82 deflects, and the sliding plate 83 slides to the second stationary point 142. During the deflection process, since the sliding plate 83 is restricted by the arc groove 14, the auxiliary shaft 82 gradually moves away from the main shaft 81. At the same time, the telescopic assembly 9 stretches, and the limit portion 93 slides in a direction away from the main shaft 81. The second spring 92 is stretched from the normal state. When the sliding plate 83 slides to the second stationary point 142, the auxiliary shaft 82 is farther away from the main shaft 81 and cannot continue to deflect.

[0069] It should be noted that initially, when the lower auxiliary shaft 82 is not deflected, there is a certain distance between the overhanging end of the second pipe and the auxiliary shaft 82. When the auxiliary shaft 82 is deflected by the main shaft 81, due to the arrangement of the arc-shaped groove 14, the auxiliary shaft 82 will gradually move away from the main shaft 81, and thus gradually move closer to the overhanging end. When the sliding plate 83 slides to the second stationary point 142, the auxiliary shaft 82 contacts the overhanging end, which does not affect the heating of the second pipe by the heating wire.

[0070] During the above deflection process, not only the distance between the auxiliary shaft 82 and the main shaft 81 changes, but also the angle changes. The telescopic assembly 9 adapts to the distance change. At the same time, the rotational connection between the auxiliary shaft 82 and the sliding plate 83 can adapt to the angle change between the auxiliary shaft 82 and the main shaft 81, thereby preventing the auxiliary shaft 82 from getting stuck during the deflection process.

[0071] However, in order to solve the problem that the second pipes on the main shaft 81 and the auxiliary shaft 82 are closely attached to each other, resulting in poor heat dissipation effect, such as Figure 9As shown, a vertical plate 75 is fixedly mounted on the slide 73. The vertical plate 75 is located at the first outlet 71. When the slide 73 slides under the action of the electromagnet, the vertical plate 75 will slide synchronously. It should be noted that the horizontal height of the top of the vertical plate 75 is greater than the horizontal height of the first end 31 but lower than the horizontal height of the second end 32. Therefore, when the vertical plate 75 slides, it will contact the first end 31 but will not affect the second end 32.

[0072] When the vertical plate 75 slides under the drive of the slide plate 73, the vertical plate 75 contacts the first end 31 and moves the first end 31. The first end 31 is tilted away from the main shaft 81 under the drive of the vertical plate 75, so that the second pipes are staggered with each other to prevent the pipes from being stuck to each other. Then, the spray assembly 10 is activated to cool the second pipes that have been separated. Constant temperature water is sprayed onto the pipe surface and the side where the pipes are in contact with each other, which has a better cooling effect on the second pipes.

[0073] In summary, in this embodiment, the staggered setting of the second pipe enables the second pipe to have an overhanging end when the temperature is being reduced. At the same time, by turning on the electromagnet, the slide plate 73 slides and drives the vertical plate 75 to slide. The slide plate 73 moves the first end 31 of the overhanging end, so that the adjacent pipes are staggered with each other, and the spray water can be sprayed between the pipes, thereby improving the cooling efficiency of the second pipe. At the same time, the partition 7 is opened, and the constant temperature water in the upper space flows to the lower space.

[0074] At the same time, an arc-shaped groove 14 is provided to limit the movement trajectory of the auxiliary shaft 82. When the second pipe needs to be sprayed, there is a certain distance between the auxiliary shaft 82 and the lower end of the second pipe, and the overhanging end can be moved by the vertical plate 75. When the second pipe needs to be heated, the auxiliary shaft 82 contacts the second pipe to play a certain supporting role and will not affect the heating of the second pipe.

[0075] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
