Description

Technical Field

[0001] The utility model relates to the technical field of sealing structures, in particular to a sealing structure for a rice slurry tank. Background Art

[0002] The rice slurry made by the grinding machine is discharged into the rice slurry tank for temporary storage. Because the amount of water added is controlled, the rice slurry in this link is relatively thick. In order to facilitate the secondary fine grinding and the feeding of rice slurry in the subsequent auxiliary material configuration link, a stirring device needs to be set in the rice slurry tank to continuously stir the slurry to prevent the solid-liquid stratification of the rice slurry and ensure the uniform addition of rice slurry in the subsequent links; the existing rice slurry tank is mainly a horizontal tank structure, with a stirring shaft arranged horizontally inside, and driven by a motor outside, so that the stirring shaft and the side wall of the rice slurry tank need to be sealed by a sealing structure.

[0003] For example, Chinese patent CN221525552U discloses a mechanical seal structure for an oil pump. The main body of the seal structure includes a dynamic ring on a rotating shaft and a static ring on an oil pump. The static ring and the dynamic ring are pressed tightly together by a spring, and the sealing is ensured during relative movement by the mirror-fitting sliding on the static ring and the dynamic ring.

[0004] However, rice slurry contains liquid and solid, and the solid in the rice slurry can easily enter between the sealing structures; the sealing mechanism is prone to sealing failure in a rice slurry environment with solid particles, requiring long-term maintenance and frequent observation to prevent leakage.

[0005] Based on this, the utility model designs a rice slurry tank sealing structure to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the utility model provides a rice slurry tank sealing structure.

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] The sealing structure of the rice slurry tank comprises:

[0009] Rice slurry tank;

[0010] A rotating shaft is located in the rice slurry groove, and two ends of the rotating shaft respectively pass through the outside of the rice slurry groove and are rotatably connected to the outer wall of the rice slurry groove through bearings;

[0011] A filter assembly, one of which is installed on each of the two inner side walls of the rice slurry tank where the rotating shaft passes through, and is covered on the outer side of the rotating shaft;

[0012] A sealing structure is installed in each of the two filter assemblies. The sealing structure includes a static sealing assembly and a dynamic sealing assembly. The static sealing assembly is installed on the inner wall of the rice slurry tank, and the dynamic sealing assembly is installed on the rotating shaft. The static sealing assembly is tightly fitted with the dynamic sealing assembly.

[0014] Furthermore, a second sealing ring is embedded in the connection between the inner wall of the rice slurry groove and the mounting ring plate.

[0015] Furthermore, the static sealing assembly includes an installation groove, a static ring and a first sealing ring. An installation groove is opened on the inner side of the rice slurry groove where the rotating shaft passes through. The static ring is fixedly installed in the installation groove and sleeved on the outer side of the rotating shaft. A first sealing ring is arranged between the static ring and the installation groove. One end of the static ring extends into the rice slurry groove and the end face is a mirror surface.

[0016] Furthermore, the dynamic sealing assembly includes a fixed cylinder, a receiving groove, a spring and a dynamic ring. The fixed cylinder is fixedly sleeved on the rotating shaft. The inner side of the end of the fixed cylinder close to the static ring is provided with a receiving groove. The dynamic ring is axially slidably inserted in the receiving groove and slidably sleeved on the rotating shaft. A spring is fixedly installed between the dynamic ring and the inner wall of the receiving groove. The end of the dynamic ring close to the static ring is a mirror surface and the mirror surface is tightly fitted with the mirror surface of the static ring.

The outer circumference of the moving ring is evenly provided with a plurality of blocking blocks, and each of the blocking blocks is slidably connected to the corresponding limiting groove.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. After the rice slurry in the rice slurry tank is filtered by the filter assembly, the liquid in the rice slurry enters the interior of the filter assembly; thereby preventing the solid in the rice slurry from contacting the static seal assembly and the dynamic seal assembly, thereby damaging the static seal assembly and the dynamic seal assembly; optimizing the environment where the static seal assembly and the dynamic seal assembly are located, increasing the service life, and avoiding frequent maintenance; at the same time, the liquid in the rice slurry enters the filter assembly and contacts the static seal assembly and the dynamic seal assembly, thereby cooling the static seal assembly and the dynamic seal assembly, thereby preventing the static seal assembly and the dynamic seal assembly from being damaged due to dry friction;

[0020] 2. The rotation of the shaft drives the dynamic seal assembly to rotate. At the same time, the dynamic seal assembly is squeezed toward the static seal assembly during the rotation process, so that the static seal assembly and the dynamic seal assembly are always in contact with each other; the static seal assembly and the inner wall of the rice slurry groove are sealed; the dynamic seal assembly and the static seal assembly are sealed by mirror friction during the rotation process to avoid leakage of liquid in the rice slurry.
