Description

Technical Field

[0001] This utility model relates to the field of ceramic firing technology, specifically to an embedded support ring firing component for ceramic production. Background Technology

[0002] Ceramic teapots, due to their unique taste when boiling water, have always been an indispensable part of life, especially in the tea ceremony. However, from the perspective of the limitations of traditional ceramic firing techniques, it is impossible to achieve 100% glazing of the bottom during actual production. If fully glazed, the bottom of the teapot will stick to the kiln shelf during high-temperature firing. Therefore, it is necessary to leave unglazed contact support points. Currently, ceramic teapots are generally fired with the bottom unglazed, resulting in drawbacks such as an unsightly unglazed bottom, easy leakage, and difficulty in cleaning. Furthermore, firing a flat-bottomed unglazed teapot directly can easily cause the middle of the bottom to bulge during the firing process. When using an electric ceramic stove to boil water, the bottom contact surface is suspended between the stove panel and the stove, causing the water to boil too slowly. The support method of traditional Ru ware full-glaze firing has obvious defects. Ru ware uses spurs for firing, and after the porcelain is fired, the spurs need to be broken off. The remaining broken pieces make it difficult for the bottom of the ceramic teapot to be aesthetically pleasing and flat, and it will have a rough feel during daily use. To address this, an embedded support ring firing component is designed. Utility Model Content

[0003] The purpose of this utility model is to provide an embedded support ring firing component for ceramic production, so as to solve the problem that the support method of traditional Ru kiln ceramic firing process requires breaking the support nails after the ceramic is fired, which makes it difficult for the bottom surface of the ceramic pot to be beautiful and flat.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An embedded support ring firing assembly for ceramic production includes a ceramic pot body and a support ring. A convex ring is coaxially fixedly connected to the bottom of the ceramic pot body, and an embedding groove is formed in the middle of the bottom of the convex ring. An embedding ring is coaxially fixedly connected to the top of the support ring. The size of the embedding groove matches the size of the embedding ring. An alumina cake is placed at the bottom of the support ring, and multiple raised feet arranged in a ring array are provided at the bottom end of the alumina cake.

[0006] Preferably, the bottom of the ceramic pot blank is flat, and its bottom edge adopts an arc-shaped transition structure.

[0007] Preferably, the center of the support ring is a circular hole, and the top surface of the support ring is divided into two inclined regions. One inclined region extends from the bottom edge of the embedded ring to the top edge of the circular hole, and is inclined downwards. The other inclined region extends from the bottom edge of the embedded ring to the top edge of the outer ring of the support ring, and is inclined downwards.

[0008] Preferably, the cross-section of the embedded ring is an isosceles triangle, and its top corners are curved, and the groove shape of the embedded groove is adapted to the shape of the embedded ring.

[0009] Preferably, the alumina cake has uniformly distributed through holes on its surface.

[0010] Preferably, the support ring is made of the same clay as the ceramic teapot blank, and the support ring has a flat bottom.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The embedded support ring firing assembly uses a detachable support ring as a temporary support, eliminating the damage to the appearance caused by traditional unglazed support points. Secondly, the support ring is an embedded design, which can be directly removed after firing and can maintain a basic level. This not only eliminates the rough feel of traditional nail firing, making daily use more comfortable, but also ensures that the bottom of the kettle is completely in contact with the heating plate of the electric ceramic stove.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution.

[0020] An embedded support ring firing assembly for ceramic production includes a ceramic pot blank 1 and a support ring 5. A convex ring 2 is coaxially fixedly connected to the bottom of the ceramic pot blank 1. An embedding groove 3 is opened in the middle of the bottom of the convex ring 2. An embedding ring 4 is coaxially fixedly connected to the top of the support ring 5. The size of the embedding groove 3 matches the embedding ring 4, so that the embedding ring 4 can be embedded, thereby completing the assembly of the pot blank and the support ring. An alumina cake 6 is placed at the bottom of the support ring 5. The alumina cake 6 adopts a hollow structure. Multiple raised feet 7 arranged in a ring array are provided at the bottom end of the alumina cake 6, wherein the number of raised feet 7 is preferably three.

[0021] The bottom of the ceramic teapot blank 1 is flat, and its bottom edge is transitioned by an arc structure.

[0022] The center of the support ring 5 is a circular hole. The top surface of the support ring 5 is divided into two inclined areas. One inclined area is from the bottom edge of the embedded ring 4 to the top edge of the circular hole, which is inclined downwards. The other inclined area is from the bottom edge of the embedded ring 4 to the top edge of the outer ring of the support ring 5, which is inclined downwards. At the same time, the outer ring of the support ring 5 retains a certain thickness to ensure the overall support strength. The inclined surface design of the support ring 5 can also prevent it from directly contacting the glaze of the ceramic pot body 1, completely eliminating the problem of adhesion during firing.

[0023] The cross-section of the embedded ring 4 is an isosceles triangle, and its top corner is rounded. The groove shape of the embedded groove 3 is adapted to the shape of the embedded ring 4. Before loading into the kiln, anti-stick powder such as alumina should be applied to the surface of the embedded ring 4. Then, the embedded ring 4 at the top of the support ring 5 is inserted into the embedded groove 3 at the bottom of the glazed ceramic teapot blank 1, thus completing the assembly of the teapot body and the support ring 5. The embedded fit of the isosceles triangle cross-section utilizes the stability of the triangular structure to provide sufficient support for the teapot body. At the same time, compared with other cross-sectional shapes, the contact area of ​​the isosceles triangle is smaller, which can minimize the risk of adhesion between the support ring 5 and the ceramic teapot blank 1, while taking into account the aesthetics of the bottom of the teapot after firing. In addition, the wide support ring 5 also provides a stable support when the entire component is placed.

[0024] The alumina cake 6 has evenly distributed through holes on its surface. When loading the kiln, the alumina cake 6 is placed with the side with the raised feet 7 facing down and placed stably on the kiln shelf. Then, the ceramic pot assembly with the support rings 5 ​​assembled is placed directly on top of the alumina cake 6. This completes all the preparations before firing. When the raised feet 7 are placed facing down, they provide stable support for the alumina cake 6 and the ceramic pot assembly above it. The through holes on the alumina cake 6 can form ventilation channels, which can assist in heat transfer under high temperature conditions and effectively avoid the problem of the bottom of the pot bulging upward due to local heat accumulation and inability to dissipate.

[0025] The support ring 5 is made of the same clay as the ceramic teapot body 1. This ensures that the support ring 5 shrinks synchronously with the teapot body during firing, effectively preventing deformation and sticking. After firing, the support ring can be removed without affecting the appearance of the teapot bottom and ensuring the quality of the finished product. The support ring 5 has a flat bottom, which provides a foundation for stable placement with the alumina cake 6.

[0026] When glazing the ceramic teapot blank 1, the outer side of the support ring 5 is the natural extension of the teapot body, and the inner side is the teapot bottom body. Both of these parts are glazed normally. The raised ring 2 and the embedded groove 3 are not glazed. After firing, the raised ring 2 no longer protrudes, but forms a nearly flat surface with the glaze layers on both sides, which is ideal. At this time, the support ring 5 is removed, which can not damage the appearance of the teapot bottom, but also ensure the overall quality of the finished product.

[0027] The specific solution is as follows: On the bottom of the ceramic teapot body 1, use a trimming tool to trim a ring 2. Control the width of the ring 2 to be about 4.5mm and the thickness to be about 0.7mm. Ensure that the ring 2 has a regular shape and a natural transition with the bottom of the ceramic teapot body 1. Avoid the ring being too thick, which will affect the flatness of the subsequent glaze, or too thin, which will result in insufficient support.

[0028] At the center of the plane of the convex ring 2, use a special grooving tool to dig out the embedding groove 3. Control the width of the embedding groove 3 to be 1.0mm and the depth to be 0.8mm. During the grooving process, it is necessary to ensure that the groove shape is symmetrical and the depth is uniform, while also taking into account the aesthetics, and avoid the groove being too deep, which would result in insufficient thickness at the bottom of the ceramic pot body 1.

[0029] Glaze the ceramic teapot body 1, but leave the raised ring 2 and the embedded groove 3 unglazed. Apply the glaze by spraying or dipping. Based on the characteristics of the heat-resistant glaze and the firing shrinkage rate, control the glaze thickness to ensure uniformity and avoid excessive glaze thickness leading to drips or excessive thinness affecting the gloss of the finished product. After glazing, wait for the glaze surface to be semi-dry, and then gently trim the glaze edges with a knife or sponge to ensure that the glaze layer on the edge of the raised ring 2 is neat and free of excess glaze accumulation. This lays the foundation for subsequent assembly with the support ring 5 and a smooth glaze surface after firing.

[0030] Check the material of the support ring 5. It must be the same as that of the ceramic pot body 1. Before loading the kiln, take alumina anti-sticking powder and brush it onto the surface of the embedded ring 4 at the top of the support ring 5. Ensure that the powder covers the surface evenly and without omissions to prevent the support ring 5 from sticking to the ceramic pot body 1 during high-temperature firing.

[0031] Hold the glazed ceramic teapot blank 1 with both hands and align the inlay groove 3 on the bottom convex ring 2 with the inlay ring 4 on the top of the support ring 5. Slowly lower and gently press down so that the inlay ring 4 is snapped into the inlay groove 3.

[0032] Select an alumina cake 6 with a diameter greater than that of the support ring 5, confirm that there are several 10mm diameter through holes on its surface, and that one side has a ring array of raised feet 7 sintered around its periphery. Place the alumina cake 6 with the raised feet 7 facing down on the kiln shelf, ensuring that the raised feet 7 are evenly stressed.

[0033] Hold the assembled ceramic teapot blank 1 and support ring 5 with both hands, and place the flat bottom of support ring 5 steadily on top of alumina cake 6.

[0034] Close the kiln, set the temperature, heating rate and holding time according to the ceramic firing process, start firing, and wait for the kiln to cool down to a safe temperature after firing. Take out the components, cool them to room temperature, and gently pry the support ring 5 to separate it from the ceramic pot body 1.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
