Description

Technical Field

[0001] This utility model relates to the field of material transportation technology, and in particular to a heat-resistant steel carrier for a vacuum industrial furnace. Background Technology

[0002] Products are loaded into a carrier during baking in a vacuum industrial furnace, and the carrier protects and supports the products.

[0003] Existing carriers are thicker to ensure their load-bearing capacity and improve structural strength, allowing them to support heavy products. However, increased thickness also increases the carrier's weight. Heavy carriers are difficult to handle manually and rely heavily on handling equipment. When used in industrial furnaces, the increased weight of the carrier also exceeds the furnace's load-bearing capacity, reducing the number of products the furnace can simultaneously support and impacting its efficiency. It should be noted that the information disclosed in the background section is for illustrative purposes only and may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a heat-resistant steel carrier for a vacuum industrial furnace to reduce the weight of the carrier.

[0005] The technical solution of this utility model is as follows:

[0006] The heat-resistant steel carrier for the vacuum industrial furnace includes:

[0007] The base plate is hollowed out; multiple polygonal frames are formed by the hollowed-out design on the base plate; the multiple polygonal frames are arranged side by side along the horizontal and radial directions of the base plate;

[0008] A baffle is connected to the outer edge of the base plate; the baffle is vertically arranged and circumferentially around the base plate.

[0009] The base plate is also hollowed out to form an elliptical frame; along the horizontal direction of the base plate, multiple polygonal frames are connected in sequence; along the vertical direction of the base plate, an elliptical frame is provided between adjacent polygonal frames; and a polygonal frame is connected to each end of the minor axis of the elliptical frame.

[0010] A further technical solution is that the baffle includes a column disposed on the base plate and a crossbar connecting adjacent columns.

[0011] A further technical solution is that the baffle is hollowed out to form a support rod; the support rod connects the crossbar and the base plate; the support rod is inclined at one end along the length of the crossbar, and an acute angle is formed between the support rod and the base plate; the inclination directions of adjacent support rods are opposite.

[0012] A further technical solution is that a groove is formed on the inner wall of the polygonal frame near the top corner of the polygonal frame; the groove is set perpendicular to the base plate.

[0013] A further technical solution is that a first extension portion is provided on the surface of the base plate away from the baffle; a notch is opened at the end of the baffle away from the base plate; when multiple base plates are stacked, the first extension portion on one base plate extends into the notch on another base plate.

[0014] A further technical solution is that a thin edge is formed on the baffle at the notch position; a second extension is also provided on the surface of the base plate away from the baffle; a gap is formed between the second extension and the first extension; when multiple base plates are stacked, the thin edge on one base plate extends into the gap on another base plate.

[0015] A further technical solution is that the thickness of the thin edge is reduced on the side away from the base plate, and the width of the gap is reduced on the side closer to the base plate.

[0016] A further technical solution includes a base; the base is disposed on an installation plane; the bottom plate is detachably disposed on the base; the bottom plate is disposed on the installation plane via the base.

[0017] A further technical solution is that, perpendicular to the base plate, a through hole and a limiting hole are formed on the base; the second extension extends into the limiting hole.

[0018] A further technical solution is that at least two limiting holes are symmetrically arranged on the base; a slotted sleeve is provided in the limiting hole; and the slotted sleeve is discontinuously provided with a gap along the axial direction of the slotted sleeve.

[0019] The beneficial technical effects of this utility model are as follows:

[0020] (1) The heat-resistant steel carrier for the vacuum industrial furnace in this utility model has a hollowed-out bottom plate. The hollowed-out structure significantly reduces the material used in the bottom plate and lightens its weight, thereby reducing the production and transportation costs of the heat-resistant steel carrier for the vacuum industrial furnace. In actual operation, the reduced weight of the heat-resistant steel carrier for the vacuum industrial furnace also reduces its occupancy of the load-bearing capacity of the vacuum industrial furnace. Oil and waste liquid on the components inside the carrier can flow out along the hollowed-out bottom plate, preventing the accumulation of oil and waste liquid. Baffles are installed on the bottom plate to block the components on the bottom plate and prevent them from sliding off the bottom plate. Furthermore, polygonal frames and elliptical frames are hollowed out on the bottom plate. The symmetrical structure of the polygonal frames facilitates uniform stress distribution, maintaining high strength while achieving lightweight design. The polygonal frames are connected and arranged sequentially along the transverse direction of the bottom plate. When the bottom plate is subjected to transverse compression or tension, the polygonal frames can undergo transverse deformation, providing support stiffness while dispersing impact. When the bottom plate is subjected to longitudinal compression or tension, the polygonal frames and elliptical frames together undergo longitudinal deformation, providing support stiffness and dispersing impact. The smooth edges of the elliptical frame effectively prevent stress concentration, ensuring uniform stress distribution when the base plate is subjected to longitudinal compression or tension, thus extending the service life of the vehicle.

[0021] (2) Furthermore, the baffle is a hollow structure composed of columns, crossbars and support rods, which further reduces the weight of the heat-resistant steel carrier of the vacuum industrial furnace. The support rods are inclined towards or away from each other to form a stable triangular structure, which effectively transmits the load in the vertical direction and ensures the structural strength of the baffle.

[0022] (3) Further, the base plate has a first extension and a second extension, and a gap is formed between the first extension and the second extension; a notch is made on the baffle of the base plate to form a thin edge. When multiple base plates are stacked, the thin edge is inserted into the gap, which improves the stability of the base plates when stacked and facilitates the storage and transportation of the base plates.

It should be noted that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the content disclosed herein.

Therefore, they should not be construed as limitations on this utility model.

[0032] Figure 1 A three-dimensional structural schematic diagram of a heat-resistant steel carrier for a vacuum industrial furnace according to an embodiment of the present disclosure is shown. Figure 2 A top view schematic diagram of a heat-resistant steel carrier for a vacuum industrial furnace according to an embodiment of this disclosure is shown. Please refer to... Figure 1 and Figure 2 The heat-resistant steel carrier for the vacuum industrial furnace includes a base plate 2, which is perforated. This perforated structure significantly reduces the material used in the base plate 2 and lightens its weight, lowering the production and transportation costs of the heat-resistant steel carrier for the vacuum industrial furnace. Multiple polygonal frames 21 are formed by the perforations on the base plate 2. These polygonal frames 21 are arranged side-by-side along the transverse and radial directions of the base plate 2. The symmetrical structure of the polygonal frames 21 facilitates uniform stress distribution, maintaining high strength while achieving lightweight construction. A baffle 3 connects to the outer edge of the base plate 2. The baffle 3 is vertically positioned and circumferentially surrounds the base plate 2. The baffle 3 blocks components on the base plate 2, preventing them from slipping off.

[0033] The base plate 2 features an elliptical frame 22 formed by cutouts. Multiple polygonal frames 21 are connected sequentially along the transverse direction of the base plate 2. When the base plate 2 is subjected to transverse compression or tension, the polygonal frames 21 can undergo transverse deformation, providing support stiffness while dispersing impact. Along the longitudinal direction of the base plate 2, elliptical frames 22 are positioned between adjacent polygonal frames 21. A polygonal frame 21 is connected to each end of the minor axis of the elliptical frame 22. When the base plate 2 is subjected to longitudinal compression or tension, the polygonal frames 21 and elliptical frames 22 together undergo longitudinal deformation, providing support stiffness and dispersing impact. The smooth edges of the elliptical frames 22 effectively prevent stress concentration, ensuring uniform stress distribution when the base plate 2 is subjected to longitudinal compression or tension, thus improving the service life of the vehicle.

[0034] Specifically, the internal temperature of the vacuum industrial furnace can reach up to 800°C during operation. The base plate 2 and baffle 3 can be made of heat-resistant steel, and the base 1 can be made of non-metallic refractory materials to withstand temperatures up to 1100°C and adapt to the high-temperature environment inside the vacuum industrial furnace.

[0035] Please refer to Figure 1 and Figure 2 The baffle 3 includes uprights 4 mounted on the base plate 2 and crossbars 5 connecting adjacent uprights 4. A separation guide groove 52 is formed on the surface of the crossbar 5 away from the base plate 2. When multiple base plates 2 are stacked, the separation guide groove 52 creates an opening between two base plates 2, allowing for easy separation of the stacked base plates 2. The baffle 3 is hollowed out to form support rods 51. Support rods 51 connect the crossbars 5 and the base plates 2. The hollowed-out structure of the baffle 3 further reduces the weight of the heat-resistant steel carrier of the vacuum industrial furnace. The support rods 51 are inclined at one end along the length of the crossbars 5, forming an acute angle with the base plates 2. Adjacent support rods 51 are inclined in opposite directions. The support rods 51 are inclined towards or away from each other to form a stable triangular structure, effectively transmitting vertical loads and ensuring the structural strength of the baffle 3. The support rods 51 enable the baffle 3 to withstand the pressure generated when multiple base plates 2 are stacked.

[0036] Preferably, a groove 211 is formed on the inner wall of the polygonal frame 21, near the apex corner of the polygonal frame 21. The groove 211 is perpendicular to the base plate 2. During casting, local heat concentration during the solidification process of the base plate 2 can easily lead to cracks. The groove 211 is formed to reduce geometric hot spots on the base plate 2, thereby reducing the risk of defects such as cracks on the base plate 2 during casting.

[0037] Figure 3 A partial cross-sectional view at point A is shown of a heat-resistant steel carrier for a vacuum industrial furnace according to an embodiment of this disclosure. Please refer to... Figure 1 and Figure 3A first extension 41 is provided on the surface of the base plate 2 away from the baffle 3. A notch 44 is provided at the end of the baffle 3 away from the base plate 2. When multiple base plates 2 are stacked, the first extension 41 on one base plate 2 extends into the notch 44 on another base plate 2. This improves the stability of the base plates 2 when stacked and facilitates the storage and transportation of the base plates 2.

[0038] Preferably, a thin edge 45 is formed on the baffle 3 at the notch 44. A second extension 43 is also provided on the surface of the base plate 2 away from the baffle 3. A gap 42 is formed between the second extension 43 and the first extension 41. When multiple base plates 2 are stacked, the thin edge 45 on one base plate 2 extends into the gap 42 on another base plate 2. This further improves the stability of the base plates 2 when stacked.

[0039] More preferably, the thickness of the thin edge 45 decreases towards the side away from the base plate 2. The width of the gap 42 decreases towards the side closer to the base plate 2. This facilitates the insertion between the thin edge 45 and the gap 42.

[0040] Figure 4 A three-dimensional structural schematic diagram of the base of a heat-resistant steel carrier for a vacuum industrial furnace according to an embodiment of the present disclosure is shown. Figure 5 A partial cross-sectional view at point B is shown of a heat-resistant steel carrier for a vacuum industrial furnace according to an embodiment of this disclosure. Please refer to... Figure 1 , Figure 3 , Figure 4 and Figure 5 It also includes a base 1. The base 1 is mounted on a mounting surface. A base plate 2 is detachably mounted on the base 1. The base plate 2 is mounted on the mounting surface via the base 1. This prevents foreign objects on the mounting surface from affecting the components on the base 1.

[0041] Preferably, a through hole 11 and a limiting hole 12 are provided on the base 1 perpendicular to the base plate 2. The through hole 11 facilitates the drainage of oily waste liquid flowing down the base plate 2, preventing oily waste liquid from accumulating on the base 1. The length of the first extension 41 extending out of the base plate 2 is shorter than the length of the second extension 43 extending out of the base plate 2. The second extension 43 extends into the limiting hole 12, restricting the relative position of the base plate 2 and the base 1, and improving the stability of the base plate 2 fixed on the base 1.

[0042] More preferably, at least two limiting holes 12 are symmetrically arranged on the base 1. A slotted sleeve 121 is provided in the limiting hole 12. A gap 122 is provided in the slotted sleeve 121 along its axial direction. The gap 122 enhances the radial deformation capability of the slotted sleeve 121, thereby enhancing the elasticity of the slotted sleeve 121. When the second extension 43 extends into the slotted sleeve 121, the slotted sleeve 121 can adapt to the second extension 43 of different sizes through elastic deformation, and the clamping force of the slotted sleeve 121 on the second extension 43 is evenly distributed, ensuring the stability of the connection between the base 1 and the base plate 2.

[0043] The specific workflow of this utility model is as follows:

[0044] Inserting the second extension 43 into the limiting hole 12 allows the base plate 2 to be quickly installed on the base 1. Connecting the thin edge 45 and gap 42 between two base plates 2 allows for rapid stacking of the two base plates 2. When subjected to lateral compression or tension, the polygonal frame 21 can undergo lateral deformation, providing support stiffness while dispersing impact. When the base plate 2 is subjected to longitudinal compression or tension, the polygonal frame 21 and the elliptical frame 22 together undergo longitudinal deformation, providing support stiffness and dispersing impact. When multiple base plates 2 are stacked, the upper base plate 2 exerts compressive stress on the lower base plate 2. The triangular stabilizing structure formed between the support rods 51, which are inclined towards or away from each other, effectively transmits the vertical load.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
