Description

Technical Field

[0001] This utility model relates to the field of ceramic glazing equipment technology, and more specifically, to a glaze supply funnel. Background Technology

[0002] With the continuous development of ceramic production technology, the bell-shaped glazing device has become an important glazing equipment in ceramic production. Due to its simple structure, convenient operation, and stable glazing quality, the bell-shaped glazing device is widely used in the production of ceramic products such as ceramic tiles, slabs, and daily-use porcelain. The equipment mainly consists of a mounting bracket, a glaze tank, a glazing bell, a glaze supply funnel, and a glaze collection tray. During operation, the ceramic blank is conveyed by a conveyor and passes under the glazing device. The glaze flows into the surface of the glazing device through the glaze supply funnel. Utilizing the surface tension of the liquid, a uniform glaze curtain is formed at the glazing device's cutting edge, thus forming a continuous and uniform glaze film on the surface of the ceramic blank, completing the glazing operation.

[0003] However, in existing glazing funnels, the glaze slurry is affected by temperature rise during long-term glazing, causing the water in the glaze slurry to evaporate. This leads to an increase in the glaze slurry's specific gravity, decreased fluidity, and even glazing defects such as glaze bubbles and branching, seriously affecting the glazing quality. This is because the traditional funnel design fails to effectively address the issues of temperature rise and fluidity changes in the glaze slurry, resulting in unstable quality during the glazing process. Utility Model Content

[0004] The present invention provides a glaze supply funnel that can solve the above-mentioned problems.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides a glaze supply funnel, including a funnel body. The bottom opening of the funnel body is connected to a glaze outlet pipe through a glaze flow rate adjustment control valve. The funnel body is provided with a glaze inlet buffer tank and an overflow pipe. The glaze inlet buffer tank is located inside the funnel body, and a screen is provided at the opening of the tank. One end of the overflow pipe is connected to the glaze slurry area of ​​the funnel body, and the other end is connected to the outside of the funnel body. The funnel body wall is provided with a cooling water circulation jacket with a circulating water inlet and a circulating water outlet.

[0007] As a further description of the above technical solution: the glaze inlet buffer tank is coaxially arranged at the center of the funnel body.

[0008] As a further description of the above technical solution: the glaze inlet buffer tank is fixedly connected to the inner wall of the funnel body by a support rod.

[0009] As a further description of the above technical solution: the screen is a cylindrical structure with several screen holes on the side wall, which is coaxially arranged with the glaze inlet buffer tank, and its lower end is inserted into the opening of the glaze inlet buffer tank.

[0010] As a further description of the above technical solution: the circulating water inlet is located at the bottom of the funnel body, and the circulating water outlet is located at the top of the funnel body.

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

[0012] 1) A glaze inlet buffer tank is set inside the glaze supply funnel, and a screen is installed at the inlet of the glaze inlet buffer tank. This can effectively filter larger particles, reduce impurities entering the funnel body, and break the air bubbles inside the glaze slurry to achieve the purpose of defoaming. By controlling the flow rate in the glaze inlet buffer tank, the direct impact and surge of the fluid at the glaze outlet are avoided. At the same time, sufficient residence time is provided to effectively eliminate air bubbles, ensure the smooth flow of the glaze slurry, and achieve a uniform glazing effect without air bubbles.

[0013] 2) The funnel body is equipped with a cooling water circulation jacket. Cooling water enters the jacket through the inlet and flows out through the outlet, carrying away the heat of the glaze slurry. This ensures that the temperature of the glaze slurry inside the funnel is low, reduces the evaporation of glaze slurry moisture, prevents the increase of glaze slurry specific gravity and the reduction of fluidity, thereby maintaining the good fluidity and stability of the glaze slurry, reducing the generation of glaze bubbles, and ensuring the quality of glazing.

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, embodiments of this utility model are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0021] Please refer to Figure 1 , Figure 2 and Figure 3 This embodiment provides a glaze supply funnel, including a funnel body 4 with a hanging ear 10. The hanging ear 10 is disposed on the outer wall of the funnel body 4. The bottom opening of the funnel body 4 is connected to the glaze outlet pipe 6 through a glaze flow rate adjustment control valve 5. The funnel body 4 is provided with a glaze inlet buffer tank 1 and an overflow pipe 7. The glaze inlet buffer tank 1 is located inside the funnel body 4, and a screen 3 is provided at the opening of the tank. One end of the overflow pipe 7 is connected to the glaze slurry area of ​​the funnel body 4, and the other end is connected to the outside of the funnel body 4. The funnel body 4 is provided with a cooling water circulation jacket 11 having a circulation inlet 8 and a circulation outlet 9.

[0022] The glaze inlet buffer tank 1 is coaxially arranged at the center of the funnel body 4 and fixedly connected to the inner wall of the funnel body 4 by a support rod 2. The screen 3 is a cylindrical structure with several screen holes on its side wall, coaxially arranged with the glaze inlet buffer tank 1, and its lower end is inserted into the opening of the glaze inlet buffer tank 1. The circulating water inlet 8 is located at the bottom of the funnel body 4, and the circulating water outlet 9 is located at the top of the funnel body 4, which to a certain extent realizes the reverse movement of glaze slurry and cooling water, thereby improving cooling efficiency.

[0023] When the above-mentioned glaze supply funnel is used, the glaze slurry pumped from the external glaze tank first enters the glaze inlet buffer tank 1 from the top of the glaze supply funnel, and overflows from the sieve holes of the mesh screen 3 at the tank opening, so as to achieve stable flow and defoaming, and retain any larger particles that may exist in the glaze inlet buffer tank 1.

[0024] The overflowing glaze slurry enters the funnel body 4. The flow rate of the glaze slurry can be controlled by the glaze discharge rate adjustment control valve 5, so that the top surface of the glaze slurry in the funnel body 4 gradually rises. After reaching the overflow pipe 7, a small amount of glaze slurry can overflow from the overflow pipe 7 and flow back to the glaze bucket.

[0025] In the above process, the glaze slurry achieves stable flow and defoaming in the glaze inlet buffer tank 1, avoiding direct impact and surge of the fluid at the glaze outlet. In addition, since the glaze slurry surface is roughly flush with the overflow outlet, a certain amount of glaze slurry is ensured to remain in the funnel body 4 for a certain period of time, allowing the air bubbles in the glaze slurry to fully overflow. Finally, a stable and uniform flow rate of bubble-free glaze is obtained at the outlet of the glaze pipe 6, which then flows to the surface of the glazing device, thereby obtaining a high-quality glazing effect.

[0026] Cooling water enters the cooling water circulation jacket 11 through the circulation inlet 8 and flows out through the circulation outlet 9, carrying away the heat from the glaze slurry. Traditional glaze funnels are single-layered structures without a cooling jacket. During continuous glazing operations, the temperature rises, causing glaze slurry moisture to evaporate, leading to increased specific gravity, decreased fluidity, and potentially glaze bubbles, thus affecting glazing quality. In this embodiment, a cooling water circulation jacket 11 with a circulation inlet 8 and a circulation outlet 9 is provided in the funnel body 4 to cool the glaze slurry, thereby maintaining stable temperature, specific gravity, and fluidity of the glaze slurry within the funnel, reducing glaze bubbles, and ensuring glazing quality.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
