Description

Technical Field

[0001] This utility model relates to the technical field of defoaming devices, specifically a vacuum defoaming device for ceramic glaze slurry. Background Technology

[0002] A ceramic glaze slurry vacuum defoaming device is a specialized piece of equipment designed for the processing of ceramic glaze slurries. Its core function is to effectively remove air bubbles from the glaze slurry using vacuum technology. Based on vacuum technology, the glaze slurry is placed in a container, the vacuum system is activated and creates a vacuum environment, causing the air bubbles in the glaze slurry to gradually expand and rise to the surface. As the air bubbles are expelled, the uniformity and density of the glaze slurry are improved, thereby ensuring the quality of ceramic products. It is widely used in various stages of ceramic production, including but not limited to the production of ceramic tiles, sanitary ware, and electrical ceramics.

[0003] Patent document CN220257226U discloses a vacuum defoaming device for ceramic glaze slurry. It discloses that the device includes a vacuum pump, a glaze pump, and a cylinder. A liquid level sensor is installed on the side of the cylinder. The cylinder is equipped with an inlet pipe, an outlet pipe, and an exhaust pipe. The liquid level sensor controls the working status of the inlet and outlet pumps through a controller. The end of the inlet pipe is formed into a waterfall-like structure. This structure consists of a cup with a diameter larger than the inlet pipe, which is connected to the end of the inlet pipe and is located in the upper part of the cylinder. The bottom of the cup is connected to the end of the inlet pipe. The glaze slurry is transported from bottom to top and flows to the bottom of the cylinder in a waterfall-like manner. Because the specific gravity of the bubbles is lower than that of the glaze slurry, when the glaze slurry is transported to the highest point in the cylinder and flows down in a waterfall-like manner, the bubbles rise to the surface of the glaze slurry and come into contact with the vacuum environment inside the cylinder. Because the internal pressure of the bubbles is greater than the vacuum environment pressure, the bubbles expand continuously until they burst, thus removing the bubbles from the glaze slurry. A glaze slurry outlet is provided at the bottom of the cylinder, and the ceramic glaze slurry after the bubbles are removed is discharged from the outlet pipe.

[0004] However, the ceramic glaze slurry vacuum defoaming devices mentioned in the above-mentioned publicly available literature mainly consider the ceramic glaze slurry vacuum defoaming device, which is not conducive to accelerating the rupture and dissolution of bubbles in the defoaming tank and improving the defoaming efficiency.

[0005] In view of this, it is necessary to develop an auxiliary defoaming mechanism to accelerate the breaking and dissolution of bubbles in the defoaming tank and improve defoaming efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a vacuum defoaming device for ceramic glaze slurry, so as to solve the technical problem of improving the defoaming efficiency of the vacuum defoaming device for ceramic glaze slurry mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a ceramic glaze slurry vacuum defoaming device, comprising: a base plate, a defoaming tank installed on the top of the base plate, and an auxiliary defoaming mechanism provided on the inner wall of the defoaming tank, the auxiliary defoaming mechanism being used to accelerate the breaking and dissolution of bubbles in the defoaming tank;

[0008] The auxiliary defoaming mechanism includes an electric slide rail, which is disposed on the inner wall of the defoaming tank. An installation plate is mounted on the output end of the electric slide rail. An ultrasonic generator is mounted on the bottom of the installation plate. A protective shell is mounted on the bottom of the installation plate. An electric telescopic rod is mounted on the inner wall of the protective shell. A transducer is mounted on the output end of the electric telescopic rod. An observation window is embedded in the inner wall of the defoaming tank. A scale plate is provided on the outer wall of the observation window. A hinge is provided on the outer wall of the defoaming tank. An inspection door is installed on the outer wall of the hinge.

[0009] Preferably, a vacuum pump is installed on the top of the defoaming tank, and the suction end of the vacuum pump extends into the interior of the defoaming tank. A glaze inlet pump is installed on the top of the bottom plate, and a glaze inlet pipe is installed on the inlet end of the glaze inlet pump. A glaze outlet pump is installed on the top of the bottom plate, and a glaze outlet pipe is installed on the outlet end of the glaze outlet pump.

[0010] Preferably, the outer wall of the mounting plate is provided with an observation mechanism, which is used to observe the changes in bubbles inside the defoaming tank.

[0011] Preferably, the observation mechanism includes a slot, which is disposed on the outer wall of the mounting plate.

[0012] Preferably, a storage rod is installed on the inner wall of the slot, and an observation plate is installed on the output end of the storage rod.

[0013] Preferably, the bottom of the observation plate is provided with an observation groove, an observation camera is installed on the inner wall of the observation groove, and a transparent protective plate is installed at the bottom of the observation groove.

[0014] Preferably, a sealing block is installed on the outer wall of the observation plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model accelerates the breaking and dissolving of bubbles in the defoaming tank by installing an auxiliary defoaming mechanism, thereby improving the defoaming efficiency. The existing vacuum defoaming efficiency is not high, so it needs to be improved. Ultrasonic waves are used to accelerate the breaking and dissolving of bubbles and improve the defoaming efficiency. First, the ultrasonic generator works and is converted into mechanical vibration through the transducer. Then, the electric slide rail drives the transducer to move left and right, and the electric telescopic rod drives the transducer to move up and down, which fully eliminates the liquid in the defoaming tank. Under the action of ultrasonic waves, the bubbles in the glaze slurry are subjected to strong impact and vibration, which quickly breaks and dissolves. The observation window can observe the approximate position of the liquid inside the defoaming tank, avoiding the situation where the liquid submerges the ultrasonic generator. At the same time, the maintenance door is opened by a hinge, which makes it convenient to inspect the inside of the defoaming tank.

[0017] 2. This utility model uses an observation mechanism to observe the changes in bubbles inside the debubbling tank. However, when bubbles are being eliminated inside the debubbling tank, it is impossible for staff to observe the changes in bubbles. Therefore, this needs to be improved. First, the operation of the retractable pole moves the observation plate out of the slot, and then the observation camera takes pictures of the bubbles inside the debubbling tank. A transparent protective plate protects the observation camera, and the pictures taken by the observation camera are transmitted to the display screen on the base plate, thus making it convenient for staff to observe the elimination of bubbles inside the tank.

First, the glaze inlet pipe 5 is added to the liquid, then the glaze inlet pump 4 operates to draw the liquid into the defoaming tank 2, then the vacuum pump 3 evacuates the air in the defoaming tank 2 to eliminate the bubbles, and after elimination, the glaze outlet pump 6 operates to discharge the treated liquid.

[0027] Please see Figure 2 and Figure 3The inner wall of the defoaming tank 2 is equipped with an auxiliary defoaming mechanism to accelerate the breaking and dissolution of bubbles in the defoaming tank 2 and improve defoaming efficiency. The auxiliary defoaming mechanism includes an electric slide rail 8, which is set on the inner wall of the defoaming tank 2. An installation plate 9 is installed at the output end of the electric slide rail 8. An ultrasonic generator 10 is installed at the bottom of the installation plate 9. A protective shell 11 is installed at the bottom of the installation plate 9. An electric telescopic rod 12 is installed on the inner wall of the protective shell 11. A transducer 13 is installed at the output end of the electric telescopic rod 12. An observation window 14 is embedded in the inner wall of the defoaming tank 2. A scale plate 15 is provided on the outer wall of the observation window 14. A hinge 16 is provided on the outer wall of the defoaming tank 2. An inspection door 17 is installed on the outer wall of the hinge 16. Some vacuum degassing processes are not very efficient, so improvements are needed. Ultrasonic waves are used to accelerate the breaking and dissolving of bubbles, thereby improving degassing efficiency. First, the ultrasonic generator 10 works and converts the sound into mechanical vibration through the transducer 13. Then, the electric slide rail 8 drives the transducer 13 to move left and right, and the electric telescopic rod 12 drives the transducer 13 to move up and down, which fully eliminates the liquid in the degassing tank 2. Under the action of ultrasonic waves, the bubbles in the glaze slurry are subjected to strong impact and vibration, which quickly break and dissolve. The observation window 14 allows observation of the approximate position of the liquid inside the degassing tank 2, preventing the liquid from submerging the ultrasonic generator 10. At the same time, the maintenance door 17 is opened by the hinge 16, making it convenient to inspect the inside of the degassing tank 2.

[0028] Please see Figure 2 and Figure 4 An observation mechanism is provided on the outer wall of the mounting plate 9 to observe the changes in bubbles inside the debubbling tank 2. The observation mechanism includes a slot 18, which is located on the outer wall of the mounting plate 9. A storage rod 19 is installed on the inner wall of the slot 18, and an observation plate 20 is installed at the output end of the storage rod 19. An observation groove 21 is provided at the bottom of the observation plate 20, and an observation camera 22 is installed on the inner wall of the observation groove 21. A transparent protective plate 23 is installed at the bottom of the observation groove 21, and a sealing block 24 is installed on the outer wall of the observation plate 20. When bubbles are being eliminated inside the debubbling tank 2, it is impossible for the staff to observe the changes in bubbles inside the debubbling tank 2. Therefore, this needs to be improved. First, the storage rod 19 moves the observation plate 20 out of the slot 18, and then the observation camera 22 takes pictures of the bubbles inside the debubbling tank 2. The transparent protective plate 23 protects the observation camera 22, and the pictures taken by the observation camera 22 are transmitted to the display screen on the base plate 1, so that the staff can easily observe the elimination of bubbles inside.

[0029] The working principle is as follows: First, the glaze inlet pipe 5 is added to the liquid. Then, the glaze inlet pump 4 operates to draw the liquid into the defoaming tank 2. Subsequently, the vacuum pump 3 evacuates the air from the defoaming tank 2 to eliminate the bubbles. After elimination, the glaze outlet pump 6 operates to discharge the treated liquid. The existing vacuum defoaming efficiency is not high, so it needs to be improved. Ultrasonic waves are used to accelerate bubble breakage and dissolution, improving defoaming efficiency. First, the ultrasonic generator 10 operates, converting the ultrasonic waves into mechanical vibrations through the transducer 13. Then, the electric slide rail 8 operates, driving the transducer 13 to move left and right, while the electric telescopic rod 12 drives the transducer 13 to move up and down, thoroughly eliminating bubbles in the liquid in the defoaming tank 2. Under the action of ultrasonic waves, the bubbles in the glaze slurry are subjected to strong impact and vibration, rapidly... The liquid inside the debubbling tank 2 is broken and dissolved, and the observation window 14 allows observation of the approximate position of the liquid inside the debubbling tank 2, preventing the liquid from submerging the ultrasonic generator 10. At the same time, the maintenance door 17 is opened via the hinge 16, making it convenient to inspect the inside of the debubbling tank 2. However, when bubbles are being eliminated inside the debubbling tank 2, it is impossible for staff to observe the changes in the bubbles inside the debubbling tank 2. Therefore, this needs to be improved. First, the operation of the storage pole 19 causes the observation plate 20 to move out of the slot 18, and then the observation camera 22 takes pictures of the bubble situation inside the debubbling tank 2. The transparent protective plate 23 protects the observation camera 22, and the pictures taken by the observation camera 22 are transmitted to the display screen on the base plate 1, thus making it convenient for staff to observe the bubble elimination situation inside.
