Description

Technical Field

[0001] This utility model relates to the field of pipeline production technology, and in particular to a windproof and heat-insulating device. Background Technology

[0002] After quenching, steel pipes need to be tempered to enhance their performance. The tempering process is generally carried out in a tempering furnace, and wind protection and heat preservation are required after heating.

[0003] Most existing tempering furnaces with lifting door panels cannot achieve a completely gapless connection with the furnace opening due to factors such as mechanical structure and thermal expansion. An appropriate gap can prevent the furnace door from experiencing excessive resistance when lifting or closing, thus ensuring the smooth operation of the furnace door. However, the gap between the furnace door and the furnace opening may lead to the leakage of heat and atmosphere, which affects the stability of the furnace temperature and the uniformity of the atmosphere, thereby affecting the tempering effect. Utility Model Content

[0044] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0046] Given that most existing tempering furnaces with lifting door panels cannot achieve a completely gapless connection with the furnace opening due to factors such as mechanical structure and thermal expansion, an appropriate gap can prevent the furnace door from experiencing excessive resistance when lifting or closing, thus ensuring the smooth operation of the furnace door. However, the gap between the furnace door and the furnace opening may lead to the leakage of heat and atmosphere, which affects the stability of the furnace temperature and the uniformity of the atmosphere, thereby affecting the tempering effect.

[0047] like Figure 1-6As shown, this utility model embodiment provides a windproof and heat-insulating device, including: a tempering furnace 1, with a frame 2 installed on one side; a winding machine 3, installed on the top of the frame 2, and a rope 4 installed on the winding machine 3; a furnace door 5, installed at the bottom of the rope 4, and the furnace door 5 is slidably connected to the frame 2; an auxiliary component 6 is provided inside the furnace door 5 to enhance the sealing of the furnace door 5 to the tempering furnace 1, the auxiliary component 6 including: a first plate 61, slidably connected to the inside of the furnace door 5; and a second sealing gasket 62, fixedly connected to one side of the first plate 61, and... A through groove matching the size of the second sealing gasket 62 is opened on one side of the furnace door 5; the first guide rod 63 is fixedly connected to the inside of the furnace door 5, and the first plate 61 is slidably connected to the first guide rod 63; the first spring 64 is sleeved on the outside of the first guide rod 63, and the two ends of the first spring 64 abut against the first plate 61 and the furnace door 5 respectively; the second plate 65 is fixedly connected to one side of the first plate 61; the limiting mechanism 66 is set inside the second plate 65, and the second plate 65 is limited to one side of the furnace door 5 by the limiting mechanism 66.

[0048] In use, the quenched and cooled steel pipe is placed inside the tempering furnace 1, and then two winding machines 3 are started simultaneously to unwind the rope 4. Under the action of gravity, the furnace door 5 will descend along the frame 2 until it blocks the furnace opening of the tempering furnace 1. Then the tempering furnace 1 is started to heat and keep the steel pipe at a certain temperature to eliminate the internal stress of the material. While keeping it at a certain temperature, the furnace door also blocks the furnace opening to prevent wind (the principle of heating and keeping the tempering furnace 1 is existing technology and will not be described in detail here). It can support the heating of spiral steel pipes with a maximum diameter of 1600mm and a maximum length of 13.2 meters. The heating temperature can be flexibly set from 30 to 45 degrees. After heating is completed, the steel pipe is transferred to the spraying process for the next step of processing through a conveyor mechanism (the conveyor mechanism is generally a conveyor belt structure, which is existing technology and will not be described in detail here).

[0049] After lowering the furnace door 5 to its lowest position, the seal is insufficient due to the movable connection between the furnace door 5 and one side of the tempering furnace 1. Since steel is more prone to oxidation during high-temperature tempering, insufficient sealing increases the formation of oxide scale, causing a decline in the surface quality of the steel pipe. To improve the seal, the operator simply pushes the second plate 65, which in turn pushes the first plate 61 and the second sealing gasket 62 towards the interior of the tempering furnace 1. During the movement of the second sealing gasket 62, it gradually adheres to the junction of the furnace opening and the furnace door 5 in the tempering furnace 1, thereby enhancing the seal between the furnace door 5 and the tempering furnace 1. After pushing the second plate 65 to one side... When the second plate 65 is flush with one side of the furnace door 5, the limiting mechanism 66 will limit the second plate 65 and keep the first spring 64 in a compressed state. The operator does not need to hold the second plate 65 at all times, which is convenient and quick. After the tempering is completed, the limiting mechanism 66 will release the second plate 65. The first plate 61 and the second sealing gasket 62 will move away from the interior of the tempering furnace 1 under the push of the first spring 64 until the second sealing gasket 62 retracts into the interior of the furnace door 5. At this time, the two winding machines 3 will be started at the same time to wind up the rope 4, thereby pulling the furnace door 5 upward along the frame 2. After the furnace opening of the tempering furnace 1 is exposed, the steel pipe can be taken out.

[0050] Furthermore, the limiting mechanism 66 includes: a slider 661, slidably connected to the inside of the second plate 65, with the top of the slider 661 extending from the inside of the second plate 65; a second guide rod 662, fixedly connected to the inside of the second plate 65, with the slider 661 slidably connected to the second guide rod 662; a second spring 663, sleeved on the outside of the second guide rod 662, with the top and bottom of the second spring 663 abutting against the slider 661 and the second plate 65 respectively; a handle 664, fixedly connected to one side of the slider 661, with the handle 664 slidably connected to the second plate 65; the portion of the slider 661 extending from the inside of the second plate 65 is provided with an inclined surface; and the inside of the furnace door 5 has a groove 51 that matches the extended portion of the slider 661.

[0051] When the second plate 65 is pushed toward the tempering furnace 1, the inclined surface of the slider 661 will first be pressed by the edge of the furnace door 5, retracting into the interior of the second plate 65, and compressing the second spring 663 outside the second guide rod 662. When the slider 661 moves to the groove 51, it will be pushed into the interior of the groove 51 by the second spring 663, thus limiting the second plate 65. When tempering is completed, the operator only needs to pull down the handle 664. The handle 664 will drive the slider 661 to slide out from the interior of the groove 51, thereby releasing the connection between the second plate 65 and the furnace door 5, and thus releasing the limitation on the second plate 65, which is convenient and quick.

[0052] Furthermore, the furnace door 5 is also equipped with an installation component 7, which facilitates the disassembly and replacement of the furnace door 5. The installation component 7 includes: a base 71, which is fixedly connected to the top of the furnace door 5, and one end of the rope 4 is tied to the base 71; screws 72, which are threaded to the side of the furnace door 5; and a slide groove 73, which is opened inside the frame 2, and the furnace door 5 is slidably connected to the slide groove 73 through the screws 72. When the second sealing gasket 62 on the furnace door 5 is damaged and the furnace door 5 needs to be removed to replace the second sealing gasket 62, first unscrew the screws 72 on both sides of the furnace door 5, and then simultaneously turn on the winding machine 3 to unwind the rope 4, so that the furnace door 5 moves down until the bottom of the furnace door 5 contacts the ground. Then, untie the rope 4 tied to the base 71, and the furnace door 5 can be removed. The operation is simple.

[0053] Furthermore, when the bottom screw 72 moves to the bottom of the slide 73, the second sealing gasket 62 is just aligned with the furnace opening of the tempering furnace 1, which makes it easy to align the second sealing gasket 62 with the furnace opening of the tempering furnace 1 when installing the furnace door 5.

[0054] Furthermore, a first sealing gasket 611 is also provided on the side of the first plate 61 near the second sealing gasket 62. Both the first sealing gasket 611 and the second sealing gasket 62 are high-temperature resistant silicone sealing strips that can withstand extreme temperatures up to 350°C, ensuring the normal use of the sealing gaskets during the tempering process.

[0055] Furthermore, the size of the second sealing gasket 62 is matched with the size of the furnace opening of the tempering furnace 1, which facilitates the enhancement of the sealing between the furnace door 5 and the tempering furnace 1.

[0056] Furthermore, the first guide rod 63 and the first spring 64 are a set, and multiple sets are installed inside the furnace door 5 to enhance the stability of the first plate 61 when it is reset.

[0057] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
