Description

Technical Field

[0001] This utility model relates to the field of kiln furniture technology, specifically to a fixed support for the inside of a purple clay kiln. Background Technology

[0002] Zisha, a unique Chinese clay craft, places extremely high demands on the kiln environment and support conditions during its firing process. In the traditional Zisha firing process, in order to make full use of the limited space inside the kiln and ensure that the clay body is heated evenly and does not deform at high temperatures, it is usually necessary to use supports (commonly known as "saggers" or "sagger boards") to place the Zisha clay body in layers.

[0003] Traditional kiln supports often consist of simple refractory bricks or cylindrical support columns temporarily stacked with kiln shelves. This structure is relatively loosely connected, and during kiln loading, the placement of the support columns is not fixed. The entire structure is prone to tilting or even collapsing when stacked high, leading to damage to the purple clay products and posing a risk to personal safety. Furthermore, since the height of the purple clay blanks to be fired typically varies, traditional supports maintain a uniform stack height for each layer, suitable for placing blanks of the same height. However, when firing shorter blanks, a significant gap remains between the top surface and the upper shelf, wasting space and affecting the kiln's operational efficiency. Additionally, during high-temperature firing, the bottom or glaze of the purple clay blank can easily stick to the kiln shelves. To prevent this, kiln workers typically sprinkle a layer of quartz sand on the shelves. Quartz sand is a consumable (contaminated during firing) and requires regular or batch-wise replenishment and replacement, necessitating convenient replenishment.

[0004] Therefore, there is an urgent need to design a new type of fixed support for the inside of a purple clay kiln to meet the current needs of purple clay firing. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a fixed support for the inside of a purple clay kiln that is structurally stable, effectively prevents sticking, is easy to operate, and has a high degree of functional integration.

[0006] The technical solution adopted by this utility model to solve the above problems is: a fixed support for a purple clay kiln, including a support plate, a support column and a top plate. The support plate is stacked to form a multi-layer structure through the support columns and the top plate is set at the top. The upper and lower adjacent sets of support plates are connected by four sets of support columns. Insert columns are provided at the four corners of the upper surface of the support plate and the upper end of the support column. Support legs are provided at the four corners of the lower surface of the support plate and the top plate. Insert holes adapted to the insertion of the insert columns are opened at the lower ends of the support legs and the support columns.

[0007] Preferably, the upper surface of the insert is provided with a circular groove, and the outer periphery of the bottom end of the four sets of inserts located on the upper surface of the support plate is also provided with an annular groove. Both the circular groove and the groove are used to place quartz sand.

[0008] Preferably, the support column includes an upper support, a handle, and a lower support from top to bottom, wherein the insertion post is located at the end of the upper support, the insertion hole is opened in the lower support, and anti-slip protrusions are arranged at equal intervals around the outer surface of the handle.

[0009] Preferably, the upper surface of the upper support of the support column and the upper surface of the groove are both provided with anti-stick pads.

[0010] Preferably, the pallet is provided with a storage box for storing quartz sand at its center. The bottom of the outer periphery of the storage box has a through hole. The storage box is fitted with a box cover for sealing the through hole. The outer periphery of the box cover extends downward to form an extended edge that fits over the outer periphery of the storage box.

[0011] Preferably, the lid has a square structure, a button is provided at the top of the lid, and a serrated structure for smoothing the quartz sand is provided at the lower end of at least one extended edge of the lid, while the extended edges of the other sides are flat.

[0012] Preferably, the tray has a limiting groove on the outer periphery of the storage box that is adapted to the insertion of the extended edge, and the depth of the limiting groove is adapted to the length of the serrated structure at the lower end of the extended edge.

[0013] Preferably, the tray is rectangular, and a set of lifting handles is provided at the midpoint of each of the four sides of its outer edge.

[0014] Preferably, the four corners of the outer edge of the pallet are provided with notches to facilitate the pouring out of quartz sand.

[0015] Compared with the prior art, this utility model has the following advantages and effects:

[0016] This utility model features interlocking posts and holes on the tray and support columns. The entire support structure is built vertically and horizontally through these interlocking structures, connecting the tray and support components into a stable overall frame. This effectively prevents collapse during kiln loading. Furthermore, the number of support column layers can be flexibly adjusted according to the height of the purple clay blanks to be fired, improving the vertical space utilization of the kiln and allowing for a larger quantity to be accommodated per firing batch, thereby increasing the kiln's turnover efficiency. A storage box stores and discharges quartz sand, and the serrated structure of the box lid facilitates smoothing the quartz sand. Anti-stick pads are placed on the main contact surfaces of each component to enhance the anti-stick effect. In addition, the design of a lifting handle and a convenient pouring notch on the tray facilitates easy replacement of the quartz sand by the operator. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0027] Example:

[0028] See Figure 1 - Figure 8 This embodiment relates to a fixed support for a purple clay kiln, specifically used for layering and stably supporting the purple clay blanks during the firing process. The support specifically includes a support plate 1, support columns 2, and a top plate 3. The support plates 1 are stacked to form a multi-layer structure via the support columns 2, with the top plate 3 positioned at the top. Adjacent sets of support plates 1 are connected by four sets of support columns 2. Inserted posts 11 are provided at the four corners of the upper surface of the support plates 1 and the upper ends of the support columns 2. Support legs 12 are provided at the four corners of the lower surfaces of the support plates 1 and the top plate 3. Insertion holes 121, adapted for insertion into the inserted posts 11, are provided at the lower ends of the support legs 12 and the support columns 2. In this embodiment, the support plates 1 and the top plate 3 are both made of refractory ceramic material, while the support columns 2 are made of corundum mullite material.

[0029] Specifically, in this embodiment, during the actual kiln loading operation, the bottommost support plate 1 is first placed at the bottom of the kiln, with its four supporting legs 12 resting on the kiln floor. Then, based on the required height of the purple clay body, the appropriate number of support columns 2 are selected (see...). Figure 4 Each layer has 4 sets of support columns 2, therefore the required number of support columns 2 should be an integer multiple of 4. Then stack the upper tray 1 on top. See Figure 5 When stacking, align and insert the insertion holes 121 at the lower end of the support column 2 with the insertion columns 11 at the four corners of the upper surface of the lower support plate 1 (or, for multiple layers, with the insertion columns 11 at the upper end of the lower support column 2). In this embodiment, the insertion columns 11 and insertion holes 121 can be fitted with a clearance fit. Stack the supports layer by layer until the required height is reached. The entire support is constructed by interlocking structures, connecting the support plate 1 and the support components into a stable overall frame, which can prevent collapse during kiln loading. The number of layers of support columns 2 can be flexibly adjusted according to the height of the purple clay body to be fired (see attached diagram). Figure 1 To showcase the upper surface structure of the support plate 1, the overall number of layers was reduced accordingly. At the same time, the height of the support column 2 was appropriately stretched. In actual use, the distance between the top surface of the purple clay blank and the bottom surface of the support plate 1 or top plate 3 above it is small, making it more compact in use. This allows a single support to accommodate purple clay blanks of different heights, which can improve the vertical space utilization of the kiln and enable the kiln to accommodate more batches of single firings, thereby improving the turnover efficiency of the kiln.

[0030] See Figure 3 and Figure 6 In this embodiment, the upper surface of the insert post 11 is provided with a circular groove 111, and the outer circumferential surface of the bottom end of the four sets of insert posts 11 located on the upper surface of the support plate 1 is also provided with annular grooves 112. Both the circular groove 111 and the groove 112 are used to place quartz sand. Before placing the support post 2, an appropriate amount of quartz sand can be filled into the annular groove 112 to isolate the support post 2 from the ground. When stacking the next layer of brackets, quartz sand can be filled into the circular groove 111 on the top surface of the insert post 11, which can effectively prevent the insert posts 11 from sticking together.

[0031] See Figure 3 In this embodiment, the support column 2 comprises, from top to bottom, an upper support 21, a handle 22, and a lower support 23. The insertion post 11 is located at the end of the upper support 21, and the insertion hole 121 is located in the lower support 23. The outer surface of the handle 22 is circumferentially distributed with anti-slip protrusions 221 at equal intervals. This allows operators to easily grip the handle 22 with the anti-slip protrusions 221 during installation or disassembly, increasing friction and effectively preventing the support column 2 from falling due to slippage, thus improving operational safety during kiln loading and unloading.

[0032] In this embodiment, both the upper surface of the upper support 21 of the support column 2 and the upper surface of the groove 112 are provided with anti-sticking gaskets 4. These anti-sticking gaskets 4 can be made of high-temperature resistant and chemically stable materials such as cordierite and mullite. After filling with quartz sand, an additional layer of anti-sticking gasket 4 is applied to further reduce the probability of adhesion. In this embodiment, the anti-sticking gasket 4 can be replaced to maintain the anti-sticking effect.

[0033] See Figure 7 In this embodiment, a storage box 16 for storing quartz sand is provided at the center of the pallet 1. A through hole 161 is opened at the bottom of the outer peripheral surface of the storage box 16. The storage box 16 is fitted with a box cover 17 for sealing the through hole 161. The outer peripheral edge of the box cover 17 extends downward to form an extended edge 172 that fits over the outer periphery of the storage box 16. This design integrates the consumable quartz sand directly into the storage box 1, eliminating the need for operators to carry additional sand containers. When quartz sand needs to be replenished, simply lift the box cover 17 upwards, disengaging the extended edge 172 and exposing the through hole 161. The quartz sand in the storage box 16 can then flow out through the through hole 161 at the bottom, replenishing the quartz sand on the upper surface of the pallet 1.

[0034] In this embodiment, the lid 17 adopts a square structure. The upper end of the lid 17 is provided with a knob 171, and the lower end of at least one extended edge 172 of the lid 17 is provided with a serrated structure 173 for smoothing the quartz sand. The other extended edges 172 are flat. The knob 171 makes it easy for the operator to grab and lift the lid 17. After the quartz sand is spread, the operator does not need to find additional tools and can directly use the lid 17 itself to perform the smoothing operation: using the side with the serrated structure 173, the accumulated quartz sand can be initially scraped and evenly distributed; then using the flat side, fine smoothing can be performed, so that a relatively flat quartz sand layer is formed on the upper surface of the tray 1.

[0035] See Figure 8 In this embodiment, the tray 1 has a limiting groove 18 on the outer periphery of the storage box 16, which is adapted to fit the extended edge 172. The depth of the limiting groove 18 is adapted to the length of the serrated structure 173 at the lower end of the extended edge 172 of the lid 17. When the lid 17 is closed, the end of its extended edge 172 can fall into the limiting groove 18, thereby limiting the extended edge 172 of the lid 17. On the one hand, this ensures the stability of the lid 17 during the transportation of the tray 1, reducing the possibility of the storage box 16 being damaged due to the displacement of the lid 17 and collision with the outer wall of the storage box 16, resulting in the overall scrapping of the tray 1. On the other hand, the limiting groove 18 cooperates with the end of the extended edge 172 to further prevent the leakage of quartz sand from the bottom end of the extended edge 172, improving the sealing performance of the storage box 16.

[0036] In this embodiment, the pallet 1 is rectangular, and a set of lifting handles 15 is provided at the midpoint of each of its four outer sides. Regardless of how the pallet 1 is positioned, the operator can always find two sets of lifting handles 15 for easy gripping from any side, facilitating the handling of the pallet 1. Furthermore, see... Figure 6 The pallet 1 has four notches 19 at the four corners of its outer edge to facilitate the pouring out of quartz sand. Quartz sand is a consumable and needs to be replaced regularly. During cleaning, the operator only needs to tilt the pallet 1 to any corner, and with the help of the broom on the extended edge 172 of the cover 17, the contaminated quartz sand flows out through the notches 19 along the surface of the pallet 1 and is poured directly into the recycling container, making it easy to replace the quartz sand.

[0037] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
