Description

Technical Field

[0001] This utility model relates to the field of ceramic preparation technology, specifically to a homogenizing device for preparing ceramic glaze. Background Technology

[0002] Ceramic glaze is a thin, glassy layer applied to the surface of ceramics. It can improve the surface properties of the ceramic body and enhance the aesthetics of the product. Ceramic glaze is usually made by mixing natural mineral raw materials such as feldspar, quartz, and kaolin, as well as certain chemical raw materials in a certain proportion, and grinding them into a slurry or dry powder.

[0003] Homogenizing equipment for ceramic glaze preparation typically uses a ball mill. This mill utilizes the impact and shearing action of grinding balls to pulverize and mix the glaze raw materials evenly. As the mill rotates, the grinding balls are lifted to a certain height under centrifugal force and friction, then fall or roll, breaking down hard raw materials such as quartz and feldspar. Since the hardness, particle size, and mineral composition of the raw materials in a glaze formulation vary, a single number of grinding balls cannot meet the homogenization needs of different ceramic glazes. When the proportion of hard raw materials in the ceramic glaze is high, more balls are often needed to break down large particles. When soft raw materials are predominant, only a small number of grinding balls are needed to avoid over-grinding and particle agglomeration. Conversely, when hard raw materials are predominant, a large number of grinding balls are required. Generally, switching the number of grinding balls in a machine is based on manual operation, which is inconvenient when the number of grinding balls is large, reducing operational efficiency.

[0004] In view of this, we propose a homogenizing device for preparing ceramic glazes. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the number of grinding balls in the existing ceramic glaze homogenizing equipment needs to be varied according to the situation, but manual operation is time-consuming. Therefore, this invention proposes a ceramic glaze preparation homogenizing equipment.

Fixed frames are provided on both sides of the ball mill body. The ball mill is rotatably connected to the fixed frames via bearings. A base is fixedly installed below the ball mill body. A bracket is fixedly installed on the top of the base. A rotating rod is rotatably installed inside the bracket. An asynchronous motor is fixedly installed on the side wall of the bracket. The output end of the asynchronous motor is fixedly connected to the rotating rod. A driving gear is fixedly connected to the outer circumference of the rotating rod. A driven gear is fixedly connected to the center of the outer circumference of the ball mill. The driving gear and the driven gear mesh with each other. A material control assembly is provided on the ball mill. The material control assembly includes: A receiving chamber is fixedly connected to the outside of the ball mill. A feed pipe is fixedly connected to the side wall of the receiving chamber. A hydraulic cylinder is fixedly installed at the end of the receiving chamber away from the ball mill. The piston end push rod of the hydraulic cylinder passes through the receiving chamber. A lifting plate is fixedly connected to the piston end push rod of the hydraulic cylinder. The lifting plate is located inside the receiving chamber. An inclined plate is fixedly connected to the inside of the storage chamber. The storage chamber is connected to the inside of the ball mill through a pipe, and a solenoid valve is fixedly installed on the pipe.

[0008] Preferably, the size of the lifting plate is fitted to the inner wall of the storage chamber, thereby restricting the internal space of the storage chamber and thus controlling the number of grinding balls inside the storage chamber.

[0009] Preferably, the internal chamber of the receiving chamber can hold the grinding balls required for the ball mill to operate, and the grinding balls enter the receiving chamber through the feed pipe.

[0010] Preferably, a sealing cap is provided on the feed pipe to open and close the feed pipe, and the solenoid valve is used to control the opening and closing of the pipe.

[0011] Preferably, the filling layer is composed of an elastic material, which has a buffering effect on the grinding balls falling from a height.

[0012] This utility model has the following advantages compared with the prior art: 1. This ceramic glaze preparation homogenizing equipment, equipped with a material control component, allows the receiving chamber to be moved upwards when grinding balls need to be added.

When it is necessary to reduce the number of balls inside the ball mill, the receiving chamber is moved downwards, allowing the grinding balls to roll into the receiving chamber by gravity.

[0018] Reference Figure 1 and 2A homogenizing device for preparing ceramic glaze includes a ball mill 1 for homogenizing and grinding ceramic glaze. Fixed frames are provided on both sides of the ball mill 1, and the ball mill 1 is rotatably connected to the fixed frames via bearings. A base 2 is fixedly installed below the ball mill 1, and a support 3 is fixedly installed on the top of the base 2. Two sets of supports 3 are provided, and a rotating rod 4 is rotatably installed between the two sets of supports 3. An asynchronous motor 5 is fixedly installed on the side wall of each set of supports 3. The output end of the asynchronous motor 5 is fixedly connected to the rotating rod 4 via the support 3. A driving gear 6 is fixedly connected to the outer circumferential surface of the rotating rod 4, and a driven gear 7 is fixedly connected to the center of the outer circumferential surface of the ball mill 1. The driving gear 6 and the driven gear 7 mesh with each other. Reference Figure 2-4 The ball mill 1 is equipped with a material control assembly 8, which includes a receiving chamber 81 fixedly connected to the outside of the ball mill 1. The receiving chamber 81 is an empty cavity. A feed pipe 82 is provided on the side wall of the receiving chamber 81. A sealing cover is provided on the feed pipe 82 to open and close the feed pipe 82. A hydraulic cylinder 83 is fixedly installed at the end of the receiving chamber 81 away from the ball mill 1. The piston rod of the hydraulic cylinder 83 passes through the receiving chamber 81. A lifting plate 84 is connected to the inside of the storage chamber 81, and the size of the lifting plate 84 fits the inner wall of the storage chamber 81. The internal cavity of the storage chamber 81 can hold the grinding balls required for the ball mill 1 to work. The grinding balls enter the storage chamber 81 through the feed pipe 82. An inclined plate 85 is fixedly connected inside the storage chamber 81. The storage chamber 81 is connected to the inside of the ball mill 1 through a through pipe 86. A solenoid valve 87 is fixedly installed on the through pipe 86. The solenoid valve 87 is used to control the opening and closing of the through pipe 86.

[0019] Reference Figure 3 The ball mill 1 has a protective structure 9 inside. The protective structure 9 includes a partition 91 on the inner wall of the ball mill 1. A support pad 92 is fixedly installed on the inner wall of the partition 91. The support pad 92 is filled with a filling layer 93, which is made of elastic material and has a buffering effect on grinding balls falling from a height. Multiple sets of support pads 92 are provided to cover the inner wall of the ball mill 1, and multiple sets of support pads 92 are connected to each other through a connecting frame 94.

[0020] Reference Figure 3 and 4There are two different working states for the ball mill 1. When it is necessary to add grinding balls to the inside of the ball mill 1, the ball mill 1 rotates and the receiving chamber 81 is positioned at the top. At this time, the sealing cover of the feed pipe 82 is opened, and grinding balls are added to the feed pipe 82. The grinding balls will roll into the receiving chamber 81. Then, the solenoid valve 87 is controlled to open the through pipe 86, and the grinding balls will fall into the ball mill 1 due to gravity. When it is necessary to reduce the number of grinding balls inside the ball mill 1, the ball mill 1 rotates and the receiving chamber 81 is positioned at the bottom. The solenoid valve 87 is controlled to open the through pipe 86, and the grinding balls will roll back into the receiving chamber 81 along the through pipe 86. It should be noted that after filling or reducing the number of grinding balls, both the feed pipe 82 and the through pipe 86 need to be kept closed.

[0021] The specific working principle of this utility model is as follows: The operator starts the asynchronous motor 5, which drives the rotating rod 4 and the driving gear 6 to rotate. Through gear meshing, the power is transmitted to the driven gear 7, which in turn drives the ball mill 1 to rotate around the bearing components on the fixed frame. Grinding balls are placed inside the ball mill 1, and then the ceramic glaze to be ground is added. When the cylinder rotates, the grinding balls are lifted to a certain height under the action of centrifugal force and friction, and then fall or roll down, achieving homogeneous grinding of the ceramic glaze. When the proportion of hard raw materials in the ceramic glaze is high, and it is necessary to break large particles through the impact of more balls, the hydraulic cylinder 83 is controlled to drive the lifting plate 84 to move up and down, changing the size of the space inside the receiving chamber 81, thereby controlling the number of grinding balls entering the ball mill 1. Then, the ball mill 1 rotates so that the receiving chamber 81 is at the top, the sealing cover of the feed pipe 82 is opened, and the grinding balls... The grinding balls enter the receiving chamber 81 through the feed pipe 82. The inclined plate 85 guides the balls as they roll down. Then, the solenoid valve 87 opens the through pipe 86, and the grinding balls fall into the ball mill 1 under gravity. When the raw material is mainly soft, only a small number of grinding balls are needed to avoid over-grinding. When it is necessary to reduce the number of grinding balls inside the ball mill 1, the ball mill 1 rotates so that the receiving chamber 81 is at the bottom. The solenoid valve 87 is then opened to open the through pipe 86. The grinding balls inside the ball mill 1 will then roll back into the receiving chamber 81 under gravity. After the operation is completed, the sealing cover of the feed pipe 82 and the solenoid valve 87 on the through pipe 86 are closed. When the grinding balls fall under gravity, the elastic material of the filling layer 93 can absorb the impact force and reduce the collision of the grinding balls with the inner wall of the ball mill 1, thereby protecting the machine body and extending the service life of the equipment.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
