Description

Technical Field

[0001] The utility model relates to the technical field of ceramic product manufacturing, in particular to a porous mold cleaning device. Background Art

[0002] In the production of ceramic sanitary products, porous molds are mostly used for high-pressure grouting molding of the green bodies. During the production of high-pressure grouting ceramic green bodies, fine particles in the slurry are likely to penetrate into the pores of the porous mold, resulting in poor water permeability and air permeability. Higher pressure and pressure holding time are required to drain the water in the slurry from the capillary channels on the surface of the mold. This not only increases energy consumption but also reduces production efficiency, leading to unstable product quality. The existing cleaning technology is to set a capillary interface communicating with the internal channels of the porous mold, and inject chemical agents into the interior of the porous mold through high pressure using this interface, and use chemical corrosion to clean the blocked channels. However, the main substances blocking the high-pressure grouting mold are inorganic fine particles with a diameter of less than 5 microns in the slurry. These fine particles usually account for more than 30% of the slurry, and most of them cannot be dissolved by hydrochloric acid. Therefore, the cleaning effect by chemical corrosion is limited, and it will cause corrosion and aging of the porous mold to a certain extent. Summary of the Utility Model

[0003] The utility model aims to at least solve one of the above technical problems in the related art to some extent. For this purpose, the utility model provides a porous mold cleaning device.

[0004] The porous mold cleaning device according to an embodiment of the utility model includes an ultrasonic cleaning tank, an overflow tank, a cleaning solution tank, and a first pipeline. An ultrasonic vibrator is provided in the ultrasonic cleaning tank. A cleaning tank opening is provided at the top of the ultrasonic cleaning tank. An overflow port is opened on the side wall of the ultrasonic cleaning tank. The overflow port is communicated with the overflow tank through a second pipeline. The second pipeline has an inverted U-shaped pipe section, and the highest point of the inverted U-shaped pipe section is higher than the cleaning tank opening. One end of the first pipeline is communicated with the cleaning solution tank, and the other end can be communicated with the capillary interface of the porous mold.

[0005] The porous mold cleaning device according to an embodiment of the utility model has at least the following beneficial effects:

[0006] Since most of the high-pressure grouting porous molds are partially blocked, and the blocked parts are usually on the surface in direct contact with the slurry, the present utility model performs fixed-point cleaning on the partially blocked surface of the porous mold. During cleaning, first align the part to be cleaned of the porous mold with the cleaning tank opening and fix it. Connect the first pipeline to the capillary interface of the porous mold, pump the cleaning liquid into the porous mold from the capillary interface, and let the cleaning liquid seep out from the part to be cleaned into the ultrasonic cleaning tank until the cleaning liquid fills the ultrasonic cleaning tank and the liquid level reaches the cleaning tank opening. Then turn on the ultrasonic vibrator to clean the surface of the porous mold. During the cleaning process, the cleaning liquid is continuously injected and overflows through the overflow port into the overflow tank. The unclogging condition of the blocked part can be judged according to the overflow speed of the cleaning liquid. The present utility model utilizes the cavitation effect of ultrasonic waves to loosen or detach the fine particles blocking the porous mold, and then utilizes the permeability and wrapping property of the cleaning agent to make the inorganic fine particles detach from the porous mold under the action of water flow, thereby unclogging the blocked pores. The present utility model does not need to use corrosive cleaning agents, and a neutral cleaning agent or clean water can achieve a better cleaning effect.

[0008] According to some embodiments of the present utility model, a vacuum extraction pipe is connected to the overflow tank, and a sealing ring is sleeved around the cleaning tank opening.

[0021] Referring to Figure 1 , a porous mold cleaning device includes an ultrasonic cleaning tank 100, an overflow tank 200, a cleaning liquid tank 300, and a first pipeline 310. An ultrasonic vibration rod 110 is provided in the ultrasonic cleaning tank 100. A cleaning tank opening 120 is provided at the top of the ultrasonic cleaning tank 100.

During the cleaning process, the cleaning liquid is continuously injected and overflows to the overflow tank 200 through the overflow port 130. The unblocked condition of the blocked part can be judged according to the overflow speed of the cleaning liquid. The present utility model uses the cavitation effect of ultrasonic waves to loosen or shed the fine particles blocking the porous mold 500, and then uses the permeability and wrapping property of the cleaning agent to make the inorganic fine particles break away from the porous mold 500 under the action of water flow, thereby dredging the blocked pores.

[0025] In some embodiments of the present utility model, a booster pump 311 and a first solenoid valve 312 are provided on the first pipeline 310. The booster pump 311 is used to increase the pressure of the cleaning liquid injected into the porous mold 500.

[0032] The following is a cleaning method applying a specific embodiment of the present utility model:

[0033] (1) Before cleaning, add the cleaning liquid into the cleaning liquid tank 300, heat it to 40 °C and keep it warm. Fix the ultrasonic cleaning tank 100 on the part to be cleaned of the porous mold 500 with a sealing ring 600. At the same time, turn on the vacuum pump to evacuate so that a vacuum is formed inside the ultrasonic cleaning tank 100, and the vacuum degree is maintained at -0.08 ± 0.01 MPa. The cleaning liquid is a mixed cleaning liquid containing penetrant, surfactant and water;

[0034] (2) During cleaning, by turning on the booster pump 311 and adjusting the pressure regulating valve 710, keep the pressure of the cleaning liquid at 0.50 ± 0.05 MPa, pump the cleaning liquid into the porous mold 500 from the capillary interface 510, and the cleaning liquid oozes from the part to be cleaned into the ultrasonic cleaning tank 100 until the ultrasonic cleaning tank 100 is filled with the cleaning liquid and the liquid level reaches the cleaning tank opening 120. Then turn on the ultrasonic vibrator bar 110 to clean the surface of the porous mold 500. During the cleaning process, the cleaning liquid is continuously injected and overflows to the overflow tank 200 through the overflow port 130;

[0035] (3) During cleaning, measure the overflow speed of the overflow cleaning liquid through the liquid level gauge 210 of the overflow tank 200. When the target requirement value is reached, turn off the ultrasonic vibrator bar 110 and the booster pump 311, and drain the cleaning liquid in the overflow tank 200 through the waste liquid pipe 230. If the outflow speed of the cleaning liquid is lower than the target requirement value, the ultrasonic cleaning time needs to be extended until the outflow speed of the cleaning liquid reaches the target value;

[0036] After cleaning, empty the cleaning liquid in the cleaning liquid tank 300, replace it with clean water, and then import it into the porous mold 500 in the same importing manner as in step (2) to rinse the cleaning liquid in the mold body. Subsequently, turn off the vacuum and introduce high-pressure gas to drain the clean water in the porous mold 500, and the cleaning is completed.

[0037] The above cleaning method uses the ultrasonic vibration rod 110 to loosen or remove the fine particles blocking the porous mold 500 through strong cavitation, and unclog the blocked pores under the combined action of the penetrant and the surfactant.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
