Abstract
Description
Technical Field
[0001] This utility model relates to the field of steam crosslinking technology, specifically to a steam crosslinking box for improving the uniformity of the internal temperature field. Background Technology
[0002] Steam crosslinking chambers are core equipment used in industrial production for the steam crosslinking process of polymer materials. They mainly provide a high-temperature and high-pressure saturated steam environment for polymer products such as cable insulation layers, pipes, and plates. By promoting the chemical crosslinking reaction of material molecules, their performance is optimized. The doors of traditional steam crosslinking chambers are usually hinged doors, which are then locked with latches.
[0003] In the existing technology, after long-term use, the hinges of hinged cabinet doors wear down, causing the door body and the door frame to become unable to be perfectly parallel and aligned. When the door body is heavy, the hinges are prone to slight deformation due to uneven force, causing the door body to sag and gaps to appear at the bottom or one side. For steam cross-linking cabinets, these gaps will cause high-temperature steam to leak continuously, forming a low-temperature zone near the door body and disrupting the uniformity of the internal temperature field. Utility Model Content
[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a steam crosslinking box that improves the uniformity of the internal temperature field, and solves the technical problem that hinged box doors are prone to gaps that damage the uniformity of the internal temperature field after long-term use.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.
[0018] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0019] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0021] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, 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.
[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0023] like Figures 1-6As shown, this invention illustrates a steam crosslinking chamber for improving the uniformity of the internal temperature field in one embodiment. Through the synergistic action of the chamber 1, the door mechanism 2, the locking assembly 3, and the clamping assembly 8, the sealing assembly 10, the locking assembly 3, and the clamping assembly 8 form a sealed and fixed structure. The double-door sliding and translational guide mechanism 7 makes operation easier and allows the door mechanism 2 to be moved easily, thereby sealing the chamber 1. Furthermore, the locking assembly 3 and the clamping assembly 8 better ensure the uniformity of the internal temperature field during operation.
[0024] The door mechanism 2 includes a first door 201 and a second door 202. The first door 201 and the second door 202 can be moved left and right to close or open the container 1. When the first door 201 and the second door 202 are close to each other, the locking component 3 and the clamping component 8 cooperate to lock the first door 201 and the second door 202.
[0025] The clamping component 8 can be adjusted up and down on the surface of the second door 202. When it moves downward to cooperate with the clamping component 8, the first door 201 can be locked by the locking component 3 to improve the uniformity of the internal temperature field.
[0026] This device is designed to prevent leakage by sealing, and through a positioning, moving, and sealing structural design, it ensures the uniformity of the internal temperature field of the steam crosslinking chamber.
[0027] See in some examples Figure 2 and Figure 3 The first T-shaped block 701 is fixed at the bottom of the door and forms a concave-convex fitting structure with the first T-shaped groove 702 at the bottom of the mounting groove 4, the connecting groove 11, and the receiving groove 5. At the same time, the lateral wing of the T-shape can restrict the displacement of the door from both the top and bottom and left and right directions. The mounting groove 4, the connecting groove 11, and the receiving groove 5 are connected. The door needs to slide from the mounting groove 4 to the connecting groove 11 and finally retract into the receiving groove 5. The first T-shaped groove 702 is continuously opened along the bottom of the three grooves. The first T-shaped block 701 can move with the door.
[0028] In some examples, such as Figure 2 , Figure 3 and Figure 4 As shown, the far ends of the first door 201 and the second door 202 will form a dynamic gap with the inner wall of the receiving groove 5 during the sliding process. High-temperature steam inside the box may overflow from this gap, causing a drop in pressure and a decrease in local temperature inside the box, which will disrupt the uniformity of the temperature field. The baffle 1001 slides synchronously with the box door. When the box door is in the closed state, the baffle 1001 and the second silicone rubber layer 1002 can fit against the inner wall of the receiving groove 5 to achieve a seal. The second silicone rubber layer 1002 is resistant to steam corrosion and will not be decomposed or swollen by high-temperature steam. After long-term use, the sealing effect is stable, reducing the maintenance cost of frequent replacement of seals.
[0029] In some examples, such as Figure 2 and Figure 3 As shown, during the long-term opening and closing of the double doors, the splicing surface will be worn due to hard contact collisions, which will lead to a decrease in the flatness of the splicing surface and an increase in the gap, thereby aggravating steam leakage. The silicone rubber layer can buffer the impact force when the door is closed, and its own wear does not affect the precision of the door splicing surface, thus extending the service life of the double door splicing surface and reducing the risk of seal failure due to wear. The second silicone rubber layer 1002 is set on the opposite side of the first box door 201 and the second box door 202. When the first box door 201 and the second box door 202 are closed together, the second silicone rubber layer 1002 is squeezed and undergoes elastic deformation, which can tightly fill the gap between the first box door 201 and the second box door 202, reducing the steam leakage rate.
[0030] In some examples, such as Figure 3 and Figure 5 As shown, the fixing block 301 is fixedly installed on the first door 201 by bolts 306. When the internal parts of the locking assembly 3 may age or be damaged after long-term use, it can be removed by bolts 306 and replaced with a new locking assembly 3. The fixing block 301 has a longitudinally opened slide groove 305 on its side. A moving block 304 is provided in the slide groove 305. The moving block 304 moves left and right in the slide groove 305. The position of the moving block 304 in the slide groove 305 can be controlled by pushing force.
[0031] A locking plate 307 is fixedly installed at one end of the movable block 304 near the second door 202, and a connecting rod 302 is fixedly installed at the other end of the movable block 304. When the movable block 304 moves in the slide 305, the locking plate 307 and the connecting rod 302 at both ends can limit the movable block 304 to prevent it from falling due to excessive movement.
[0032] In some examples, such as Figure 5 As shown, a spring 303 is provided between the connecting rod 302 and the fixing block 301. There are two springs 303. The two springs 303 make the spring force more balanced. A spring 303 on one side may cause uneven force or displacement and shaking, which will aggravate the friction between the parts. The springs 303 on both sides reduce unnecessary wear by stabilizing the movement.
[0033] The two ends of the spring 303 are fixed to the connecting rod 302 and the fixing block 301 respectively. Its elastic force is transmitted to the locking plate 307 through the moving block 304, forcing the locking plate 307 to always be tightly pressed against the locking component 8 of the second door 202, providing a stable locking force, avoiding locking failure due to environmental changes, and indirectly ensuring the continuous compression of the first silicone rubber layer 203.
[0034] In some examples, such as Figure 6As shown, a second T-shaped groove 9 is provided on the front side wall of the second door 202 near the first door 201. The second T-shaped groove 9 facilitates the sliding of the second T-shaped block 801 inside and adjusts its position up and down to ensure that the locking component 3 is locked and released.
[0035] A locking block 802 is fixedly installed on the front side of the second T-shaped block 801. When the locking block 802 moves up and down through the second T-shaped groove 9 and the second T-shaped block 801, when it moves to the upper end of the moving block 304, the locking plate 307 is limited and locked to the current position. At this time, the first box door 201 and the second box door 202 are tightly fitted on opposite sides, which reduces leakage to a certain extent and improves the uniformity of the temperature field.
[0036] In some examples, such as Figure 2 As shown, both the locking component 3 and the clamping component 8 are provided with three sets. The multiple locking components 3 can significantly improve the sealing performance and solve the defects of pressure concentration and uneven force on the sealing surface that may occur with a single locking component 3. At the same time, the clamping component 8 is provided to work in conjunction with it.
[0037] Near the first door 201, there are three placement slots 6 that cooperate with the locking component 3. When the first door 201 is moved, when the first door 201 is pushed to one side, the locking component 3 can move to the placement slot 6 on one side, so as to avoid the locking component 3 being blocked and to facilitate the first door 2051 being moved to one side.
[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
