Description

Technical Field

[0001] This utility model relates to the field of ceramic tile production, and in particular to a ceramic tile blank glazing device. Background Technology

[0002] Glazing is a crucial step in the process of ceramic tile firing, involving the even application of a viscous liquid glaze onto the tile surface. Since glazes are typically emulsions, they are prone to separation after prolonged standing. Common glazing equipment places the glaze entirely within a large tank, controlling the flow rate through valves. Because the glaze remains stationary in the tank, it's essential to limit the amount of glaze added at once to minimize separation. This method results in frequent glazing during the tile application process, increasing the workload for manual labor. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a ceramic tile blank glazing device.

[0004] This utility model is achieved using the following technical solution: a ceramic tile blank glazing device, including a glaze hopper, with a glazing nozzle at the bottom of the glaze hopper, the glaze hopper including a main hopper and a distribution hopper, the distribution hopper being mounted on a frame and positioned above a conveyor belt, the conveyor belt being used to transport ceramic tiles sequentially through the distribution hopper, the main hopper and the distribution hopper being connected by a pipe, and the glazing nozzle being located at the bottom of the distribution hopper and facing the conveyor belt;

[0005] The material distribution bin is equipped with a bypass mixing component, which is located on one side of the material distribution bin and connected to it. The bypass mixing component and the material distribution bin are connected by a pipeline, and a delivery pump is provided on the pipeline to push the glaze to circulate between the material distribution bin and the bypass mixing component.

[0006] The bypass mixing assembly includes a mixing section and a stirring section. The mixing section is located on one side of the distribution bin and is connected to the distribution bin through the pipeline. The stirring section is located inside the mixing section and is used to stir the glaze inside the mixing section.

[0007] The mixing section includes a mixing tank, with a feed inlet at the top and a discharge outlet at the bottom. The discharge outlet of the mixing tank is connected to the top of the distribution bin via a pipeline, and the feed inlet of the mixing tank is connected to the bottom of the distribution bin via a pipeline.

[0008] The conveying pumps are respectively installed on the pipelines connected to the feed port and the discharge port.

[0009] The stirring unit includes a stirring shaft and stirring blades. The stirring shaft extends into the mixing tank, and the stirring blades extend into the mixing tank and rotate under the drive of the stirring shaft.

[0010] The stirring blade and the stirring shaft are hollow. The stirring blade has a vent hole. The stirring shaft is connected to an air supply hose, which delivers high-pressure air into the stirring blade.

[0011] Compared to existing technologies, in this invention, the glaze in the distribution bin continuously circulates between the bypass mixing component and the distribution bin during the glazing process due to the action of the delivery pump. This reduces the occurrence of sedimentation of glaze components. Simultaneously, the main silo supplies material to each distribution bin, ensuring the need for multiple glazing applications on the brick blanks and reducing labor intensity.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0018] Reference Figure 1-4A ceramic tile blank glazing device includes a glaze silo 1 with a glazing inlet 13 at its bottom. The glaze silo 1 includes a main silo 11 and a distribution silo 12. The distribution silo 12 is mounted on a frame and positioned above a conveyor belt, which transports the ceramic tiles sequentially through the distribution silo 12. The main silo 11 and the distribution silo 12 are connected by a pipe. The glazing inlet 13 is located at the bottom of the distribution silo 12 and faces the conveyor belt. In this embodiment, the distribution silo 12 is equipped with a bypass mixing component 2, which is located on one side of the distribution silo 12 and connected to it. The bypass mixing component 2 and the distribution silo 12 are connected by a pipeline, on which a delivery pump 23 is installed to circulate the glaze between the distribution silo 12 and the bypass mixing component 2. During the glazing process, the glaze in the distribution silo 12 continuously circulates between the bypass mixing component 2 and the distribution silo 12 due to the action of the delivery pump 23, thereby reducing the occurrence of sedimentation of components in the glaze. At the same time, the main material bin 11 supplies materials to each sub-bin 12 to ensure the need for multiple glazing of the brick blanks and reduce labor intensity.

[0019] The bypass mixing assembly 2 in this embodiment includes a mixing section 21 and a stirring section 22. The mixing section 21 is located on one side of the distribution bin 12 and is connected to the distribution bin 12 via a pipeline. The stirring section 22 is located inside the mixing section 21 and is used to stir the glaze within the mixing section 21. The mixing section 21 includes a mixing tank 211. The upper part of the mixing tank 211 has a feed port 212, and the lower part of the mixing tank 211 has a discharge port 213. The discharge port 213 of the mixing tank 211 is connected to the upper part of the distribution bin 12 via a pipeline, and the feed port 212 of the mixing tank 211 is connected to the lower part of the distribution bin 12 via a pipeline. Furthermore, a delivery pump 23 is installed in the pipeline at the feed port 212 and the discharge port 213 to ensure the stability of the glaze circulation between the mixing tank 211 and the distribution bin 12.

[0020] In addition to using circulation to mitigate glaze stratification, stirring can also be performed simultaneously with circulation. Specifically, the stirring unit 22 in this application includes a stirring shaft 221 and stirring blades 222. The stirring shaft 221 extends into the mixing tank 211, and the stirring blades 222 extend into the mixing tank 211 and rotate under the drive of the stirring shaft 221. By using circulation and stirring, the glaze in the distribution bin 12 is always in a dynamic state. That is, the materials in the glaze are always in a state of stirring and mixing, which can reduce the occurrence of stratification caused by the glaze being left to stand in the distribution bin 12 for a long time. As a result, the amount of glaze that can be added at one time can be increased, reducing the frequency of adding glaze during the production process. Therefore, the workload of manual labor can be reduced.

[0021] Based on this, high-pressure air can be introduced into the distribution bin 12 to further enhance the mixing effect and reduce stratification. Specifically, in this embodiment, the stirring blade 222 and the stirring shaft 221 are hollow, and the stirring blade 222 has a vent hole 223. The vent hole 223 communicates with the hollow part of the stirring shaft 221 to form an air delivery channel 224. The vent hole 223 and the stirring shaft 221 are connected to an air delivery hose, which delivers high-pressure air into the stirring blade 222. The air delivery hose is inserted into the centrally controlled stirring shaft 221 from the central axis direction. During the stirring process, the air delivery hose is kept as entangled as possible. The specific connection method is as follows: a connector 24 is inserted into the end of the air supply hose. Several steel balls 241 are spaced apart along the circumferential direction on the outer edge of the connector 24. Correspondingly, an annular groove 243 is opened at the end of the stirring shaft 221. The annular groove 243 is opened on the inner wall of the hollow part. When the connector 24 is inserted into the hollow part of the stirring shaft 221, the steel balls 241 are locked in the annular groove 243. A receiving hole is opened on the outer edge of the connector 24 to hold the steel balls 241. A vent hole is opened along the axial direction of the connector 24. The vent hole is used to communicate with the air supply hose. The receiving hole is on the outer wall of the vent hole and surrounds the vent hole. An elastic element 242 is fixed on the inner wall of the vent hole at the position corresponding to each receiving hole. The steel balls 241 are placed between the elastic element 242 and the receiving hole, so that the steel balls 241 can be pushed by the elastic element 242 and pressed against the receiving hole. When inserted, the outer edge of the annular groove 243 will squeeze the steel ball 241, which will cause the elastic element 242 to deform. When the connector 24 is inserted into place, the steel ball 241 will return to its original position, and the edge of the steel ball 241 will be pressed against the annular groove 243. This will not affect the rotation of the stirring shaft 221, and will also reduce the possibility of the air delivery hose getting tangled.

[0022] Compared to existing technologies, in this invention, during the glazing process, the glaze in the distribution bin 12 continuously circulates between the bypass mixing component 2 and the distribution bin 12 due to the action of the delivery pump 23. This reduces the occurrence of sedimentation of glaze components. Simultaneously, the main hopper 11 supplies material to each distribution bin 12, ensuring the need for multiple glazing applications on the brick blanks and reducing labor intensity.

[0023] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
