Description

Technical Field

[0001] This utility model relates to the field of silicon carbide product drying technology, and in particular to a material rack assembly for drying silicon carbide product blanks. Background Technology

[0002] Silicon carbide products mainly refer to silicon carbide ceramic bolts. The processing of silicon carbide ceramic bolts involves batching, mixing, extruding into cylindrical blanks, drying, and shaping before subsequent operations such as sintering and machining can be performed. Because the drying oven dries multiple silicon carbide ceramic bolt blanks at once, racks are needed to support the blanks to be dried.

[0003] In actual processing, for large-volume loading, multi-layer racks are generally selected, with silicon carbide ceramic bolt blanks placed on each shelf. To avoid ineffective drying of the internal silicon carbide ceramic bolt blanks due to stacking, and to ensure each blank is dried as thoroughly as possible, each blank is placed vertically upside down on the shelf with the bolt head at the bottom and the shank at the top. However, this placement can easily cause the blanks to tip over during loading and unloading from the drying oven due to vibrations or shaking from the rack movement. Especially when loading into the oven, tipping requires realignment, which is time-consuming and disrupts the workflow. Utility Model Content

[0004] The purpose of this utility model is to provide a rack assembly for drying silicon carbide product blanks, so as to solve the problem that when silicon carbide ceramic bolt blanks are placed vertically on multi-layer racks, the vibration or shaking when the racks are moved can easily cause the silicon carbide ceramic bolt blanks to tip over.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A drying rack assembly for silicon carbide product preforms includes a movable base and multiple shelf units, wherein the multiple shelf units are detachably mounted on the movable base in a vertical direction; wherein...

[0007] The shelf unit includes a load-bearing plate, a spring-loaded shelf, support legs, springs, and a hook assembly. The support legs are distributed at four corners and are vertically installed on the bottom surface of the load-bearing plate. The spring-loaded shelf is slidably connected to the four support legs and is located below the load-bearing plate. The two ends of the spring are respectively connected to the load-bearing plate and the spring-loaded shelf. The upper and lower hooks of at least one hook assembly are mutually adapted and respectively installed on the load-bearing plate and the spring-loaded shelf. The top surface of the load-bearing plate has positioning protrusions distributed at four corners, and the support legs are provided with grooves that are adapted to the positioning protrusions.

[0008] A further technical solution is to install a stop bar between adjacent legs.

[0009] A further technical solution is that the movable base includes casters and a spring-loaded base plate, and the bottom surface of the spring-loaded base plate is rotatably connected to at least three of the casters.

[0010] A further technical solution is that the omnidirectional wheel has an annular groove on its surface.

[0011] A further technical solution is: the elastic pressing layer plate and the elastic pressing base plate have the same structure but are arranged in opposite directions, both including a perforated plate, a metal mesh and a flexible high-temperature resistant layer, the metal mesh is stretched on the perforated plate, and the flexible high-temperature resistant layer is installed on the outer surface of the metal mesh.

[0012] A further technical solution is: the flexible high-temperature resistant aluminum silicate cotton felt.

[0013] A further technical solution is that there is a gap between the perforated plate and the metal mesh.

[0014] A further technical solution is that the head of the silicon carbide product blank on the material rack assembly faces downwards.

[0029] This implementation example Figure 1 , Figure 2 and Figure 3 As shown, the assembly for drying silicon carbide product blanks includes a movable base 1 and multiple shelf units 2, which are detachably mounted on the movable base 1 along the vertical direction; wherein,

[0030] The shelf unit 2 includes a load-bearing plate 3, a spring-loaded shelf 4, support legs 5, springs 6, and a hook assembly 7. The support legs 5 are distributed at four corners and are vertically installed on the bottom surface of the load-bearing plate 3. The spring-loaded shelf 4 is slidably connected to the four support legs 5 and is located below the load-bearing plate 3. The two ends of the springs 6 are connected to the load-bearing plate 3 and the spring-loaded shelf 4, respectively. The upper hook and lower hook of at least one hook assembly 7 are mutually adapted and installed on the load-bearing plate 3 and the spring-loaded shelf 4, respectively. The top surface of the load-bearing plate 3 has positioning protrusions 8 distributed at four corners, and the support legs 5 are provided with grooves that are adapted to the positioning protrusions 8.

[0031] To facilitate the quick and easy upright placement of silicon carbide product blanks 15, generally, after placing one layer of silicon carbide product blanks 15, the next shelf unit 2 is added, and this process continues until all shelf units 2 on a material rack assembly are installed. When placing shelf units 2, the spring-loaded shelf 4 above one layer of silicon carbide product blank 15, under the action of spring 6, works together with the load-bearing plate 3 below it or with the movable base 1 below it to clamp the upright silicon carbide product blank 15, preventing it from tipping over due to vibration or shaking when the material rack assembly moves, thus ensuring the smooth progress of the drying process.

[0032] It is worth noting that the elastic layer 4 itself has a certain degree of elasticity. For example, a layer of high-temperature resistant silicone is provided on its surface. First, it serves as a buffer to prevent damage to the silicon carbide product blank 15. Second, when it is pressed by the silicon carbide product blank 15, it will form a depression to prevent the silicon carbide product blank 15 from moving and improve the effect of the stable and upright silicon carbide product blank 15.

[0033] Preferably, a stop bar 9 is provided between adjacent support legs 5.

[0034] The lever 9 can be arranged in a circle around the perimeter to prevent the silicon carbide product blank 15 from actually tipping over and falling.

[0035] Preferably, the movable base 1 includes casters 10 and a spring-loaded base plate 11, with the bottom surface of the spring-loaded base plate 11 rotatably connected to at least three casters 10.

[0036] The casters 10 facilitate the movement of the material rack, and the spring-loaded base plate 11 is used to support the bottom silicon carbide product blank 15.

[0037] It is worth noting that the spring-loaded base plate 11 has a certain degree of elasticity. For example, a layer of high-temperature resistant silicone is provided on its surface. This serves two purposes: first, to act as a buffer to prevent damage to the silicon carbide product blank 15; and second, to form a depression when pressed by the silicon carbide product blank 15, preventing the silicon carbide product blank 15 from moving and improving the stability and uprightness of the silicon carbide product blank 15.

[0038] Preferably, the caster wheel 10 has an annular groove on its surface.

[0039] Generally, in order to facilitate the positioning and movement of the material rack, a track is set inside the drying oven, and the annular groove on the universal wheel 10 is just right to match the track. Example

[0040] Based on the above embodiments, this embodiment, for example Figure 4 and Figure 5 As shown, the elastic layer plate 4 and the elastic base plate 11 have the same structure but are arranged in opposite directions. Both include a perforated plate 12, a metal mesh 13 and a flexible high-temperature resistant layer 14. The metal mesh 13 is stretched on the perforated plate 12, and the flexible high-temperature resistant layer 14 is installed on the outer surface of the metal mesh 13.

[0041] The perforated plate 12 and the metal mesh 13 can ensure the permeability of airflow; the metal mesh 13 has a certain tension elasticity, which, together with the flexible high-temperature resistant layer 14, serves two purposes: first, to act as a buffer to prevent damage to the silicon carbide product blank 15; and second, when subjected to pressure from the silicon carbide product blank 15, it will form a depression to prevent the silicon carbide product blank 15 from moving, thereby improving the effect of stabilizing and keeping the silicon carbide product blank 15 upright.

[0042] Preferably, the flexible high-temperature resistant layer is 14 aluminum silicate cotton felt.

[0043] Preferably, there is a gap between the perforated plate 12 and the metal mesh 13.

[0044] The gap serves two purposes: firstly, as a ventilation channel, and secondly, to accommodate the deformation of the metal mesh 13.

[0045] Preferably, the silicon carbide product blank 15 on the material rack assembly has its head facing downwards.

[0046] The silicon carbide product blank 15 is placed with its head facing down because its center of gravity is close to its head. This placement helps to ensure the stability of the silicon carbide product blank 15 when it is upright.

[0047] The working process of this utility model is as follows: First, a batch of silicon carbide product blanks 15 are placed vertically on the moving base 1 with their heads facing down until all the silicon carbide product blanks 15 in the current layer are placed. Then, the shelf unit 2 is placed on the moving base 1, and then silicon carbide product blanks 15 are placed on the shelf unit 2 until it is full. Then, the shelf unit 2 is placed again, and so on until the material rack is fully loaded.

[0048] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
