Description

Technical Field

[0001] This utility model relates to the field of electrical porcelain manufacturing technology, and in particular to a closed-loop glaze slurry control device for electrical porcelain glazing. Background Technology

[0002] In the field of electrical porcelain manufacturing, the glazing process for blanks places extremely high demands on the stability of the glaze slurry level, temperature uniformity, and anti-settling ability, which directly affects the quality of the glaze layer and production efficiency. In traditional rotary glazing machines, the glaze tank is usually a single container structure, with the glaze slurry stored directly inside. The slurry is replenished manually or mechanically, lacking an effective level control and circulation mechanism. During blank immersion, the glaze slurry in the tank is prone to sedimentation due to prolonged standing, resulting in uneven glaze thickness. Simultaneously, the glaze slurry level fluctuates significantly due to factors such as blank entry / exit and evaporation, making it difficult to ensure consistent glazing height across different blanks. Furthermore, some glaze tanks lack dedicated venting structures, allowing trapped air zones to form inside the blanks when immersed in the glaze slurry. This prevents sufficient glazing of the "inner eye" area near the central blind hole, leading to quality defects. Therefore, it is necessary to propose a closed-loop glaze slurry control device for electrical porcelain glazing to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide a closed-loop glaze slurry control device for glazing electric porcelain, so as to solve the problem that traditional glaze tanks are prone to quality defects in the glazing process of blanks.

[0004] This utility model provides a closed-loop glaze slurry control device for glazing electrical porcelain, including a small glaze tank, an overflow gate, an external glaze storage tank, a glaze slurry temperature controller, a U-shaped vent pipe, a glaze slurry delivery pump, a glaze slurry return pump, a working tank, an overflow tank, an overflow pump, and a stirring device. The working tank is located inside the small glaze tank, and the overflow tank is located inside the small glaze tank but outside the working tank. An overflow gate and a diaphragm pump are installed between the working tank and the overflow tank. The U-shaped vent pipe is located inside the working tank and its end extends to the outside of the small glaze tank. The glaze slurry temperature controller is located inside the external glaze storage tank, and a stirring device is installed inside the external glaze storage tank. The external glaze storage tank is connected to the small glaze tank via the glaze slurry delivery pump, and the bottom of the overflow tank is connected to the upper side of the small glaze tank via the overflow pump. The small glaze tank is connected to the external glaze storage tank via the glaze slurry return pump.

[0005] Furthermore, the small glazing tank can accommodate two 550kN electric porcelain blanks for glazing.

[0006] Furthermore, the glaze temperature is controlled by electric heating.

[0007] Furthermore, a glaze slurry delivery port is provided on the side plate of the small glaze tank, and the glaze slurry delivery port is connected to a glaze slurry pump.

[0008] Furthermore, a funnel-shaped glaze return port is provided at the bottom center of the small glaze tank, and the glaze return port is connected to the glaze return pump.

[0009] This utility model has the following beneficial effects: Through the separation design of the working tank and the overflow tank and the cooperation of the overflow gate, this utility model achieves stable control of the glaze slurry level. The circulation loop formed by the external glaze storage tank and the conveying and returning glaze slurry pump, combined with the stirring device, effectively avoids glaze slurry sedimentation and ensures temperature uniformity. The U-shaped vent pipe solves the problem of local unglazing caused by air trapped in the inner cavity of the blank. The overall structure realizes closed-loop control of glaze slurry supply through mechanical design, which significantly improves the accuracy and consistency of glazing of electric porcelain blanks and reduces the product defect rate caused by glaze slurry fluctuations or air trapped.

Detailed Implementation

[0014] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be pointed out that the following detailed description is illustrative and intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0015] Please see Figure 1 and Figure 2 This utility model provides a closed-loop glaze slurry control device for glazing electric porcelain, including a small glaze tank D1, an overflow gate D2, an external glaze storage tank D3, a glaze slurry temperature control D4, a U-shaped vent pipe D5, a glaze slurry conveying pump D6, a glaze slurry return pump D7, a working tank D8, an overflow tank D9, an overflow pump D10, and a stirring device D11.

[0016] The working tank D8 is located inside the small glazing tank D1, serving as the area for direct glazing of the blanks, ensuring that the glaze evenly covers the target area after immersion. The overflow tank D9 is located inside the small glazing tank D1 and outside the working tank D8, collecting excess glaze from the working tank D8 to prevent spillage and equipment contamination. Simultaneously, the overflow pump D10 pumps the glaze from the overflow tank D9 back to the upper side of the small glazing tank D1, achieving glaze recycling and reducing waste. An overflow gate D2 and a diaphragm pump are installed between the working tank D8 and the overflow tank D9. The overflow gate D2 can be mechanically adjusted to precisely control the glaze level in the working tank D8, ensuring level fluctuations are <±1.5mm and guaranteeing consistent glazing heights for different blanks. The diaphragm pump assists in adjusting the overflow speed, further improving level stability.

[0017] The U-shaped vent pipe D5 is installed inside the working tank D8 and extends to the outside of the small glaze tank D1. One end of it extends into the vicinity of the blind hole in the center of the blank, and the other end is connected to the atmosphere. It can effectively discharge the trapped air formed in the inner cavity when the blank is immersed in the glaze slurry, avoid the defect of unglazed "inner eye" area caused by air blockage, and ensure complete glaze coverage.

[0018] The glaze slurry temperature control D4 is located inside the external glaze storage tank D3. It uses electric heating to stably control the glaze slurry temperature at 30±5℃. The temperature is adjustable to avoid temperature fluctuations affecting the glaze slurry viscosity, thereby ensuring uniform glaze layer thickness. The external glaze storage tank D3 is also equipped with a stirring device D11, which continuously stirs to prevent glaze slurry sedimentation and ensure uniform glaze slurry composition. The external glaze storage tank D3 is connected to the small glaze tank D1 via a glaze slurry pump D6. A glaze slurry delivery port is located on the side plate of the small glaze tank D1, connected to the glaze slurry pump D6. The pump D6 quantitatively delivers the temperature-controlled and stirred glaze slurry from the external glaze storage tank D3 to the working tank D8, continuously replenishing the working tank D8 with fresh glaze slurry. The small glaze tank D1 is connected to the external glaze storage tank D3 via a return glaze slurry pump D7. A funnel-shaped glaze slurry return port is located at the bottom center of the small glaze tank D1, connected to the return glaze slurry pump D7. The return glaze slurry pump D7 draws the glaze slurry from the bottom of the small glaze tank D1 back to the external glaze storage tank D3, forming a closed-loop cycle of "glaze storage-transportation-return," ensuring the glaze slurry remains in a flowing state, further preventing sedimentation and maintaining temperature uniformity. The small glaze tank D1 can accommodate two 550kN electrical porcelain blanks for glazing. The dual-station design allows for simultaneous processing of two blanks, significantly improving production efficiency.

[0019] The working process of the device is as follows: First, the glaze slurry in the external glaze storage tank D3 is kept at a stable temperature and has a uniform composition under the heating of the glaze slurry temperature control device D4 and the stirring of the stirring device. Then, the glaze slurry pump D6 pumps the glaze slurry in the external glaze storage tank D3 into the working tank D8 of the small glaze tank D1 through the glaze slurry delivery port. When the glaze slurry in the working tank D8 reaches the set height, the excess glaze slurry overflows through the overflow gate D2 to the overflow tank D9, and is then pumped back to the small glaze tank D1 by the overflow pump D10. The blank is held by the robot and immersed in the glaze slurry in the working tank D8. The U-shaped vent pipe D5 discharges the air from the inner cavity of the blank to ensure that the glaze slurry fully covers it. After the glazing is completed, the return glaze slurry pump D7 pumps the glaze slurry in the small glaze tank D1 back to the external glaze storage tank D3 through the funnel-shaped glaze slurry return port to achieve recycling.

[0020] This utility model achieves precise control of glaze slurry level, temperature, and composition, as well as air venting function in the blank cavity through optimized mechanical structure design. It effectively solves problems such as large fluctuations in glaze slurry level, easy sedimentation of glaze slurry, and air trapping in blanks without glazing, thus improving the glazing accuracy and consistency of electric porcelain blanks, reducing product defect rate, and reducing material waste and improving production efficiency through glaze slurry recycling.
