Description

Technical Field

[0001] This utility model relates to the field of high-efficiency mixing tank technology, and in particular to a sealing structure for a high-efficiency mixing tank used in a rubber manufacturing plant. Background Technology

[0002] A mixing tank is used for stirring, mixing, blending, and homogenizing materials. Stainless steel mixing tanks are designed with standardized and user-friendly structures and configurations according to production process requirements. During the mixing process, the mixing tank can realize feeding control, discharging control, stirring control, and other manual and automatic controls. High-efficiency mixing tanks, also known as high-efficiency mixing vessels, are industrial mixing equipment widely used in chemical, mining, and water treatment fields. Their core function is to achieve efficient mixing of materials through mechanical stirring.

[0003] However, the sealing of high-efficiency mixing tanks relies on the fit between the tank lid and the tank body to achieve a seal, or the addition of a sealing ring between the tank body and the tank lid. The sealing ring will lose its elasticity due to prolonged compression, thus causing the high-efficiency mixing tank to fail to seal. Utility Model Content

[0004] The technical problem this invention aims to solve is that the sealing of a high-efficiency mixing tank relies on the fit between the tank lid and the tank body, or the addition of a sealing ring between the tank body and the tank lid. However, prolonged compression of the sealing ring can lead to a decrease in its elasticity, resulting in the failure of the high-efficiency mixing tank's seal.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A sealing structure for a high-efficiency mixing tank used in a rubber manufacturing plant includes a mixing tank and a sealing cover. The top of the mixing tank is provided with a sealing groove. A sealing ring is provided between the mixing tank and the sealing cover. The outer side of the bottom end of the sealing ring is fixed to the inner wall of the mixing tank, and the sealing ring is snapped into the inner side of the sealing groove. An elastic inner support ring is installed on the inner side of the sealing ring. The cross-section of the elastic inner support ring is U-shaped, and multiple sets of elastic support members are fixed in an annular array inside the elastic inner support ring. The elastic support members include multiple reinforcing springs.

[0007] Preferably, the reinforcing spring is V-shaped and made of spring steel.

[0008] Preferably, two internal reinforcing rings are fixed inside the sealing ring. The internal reinforcing ring includes an inner ring, and a stirring shaft hole is provided through the center of the sealing cover. The inner diameter of the inner ring is larger than the diameter of the stirring shaft hole.

[0009] Preferably, the outer surface of the inner ring is provided with a plurality of elastic support rods arranged in a ring array, and the ends of the elastic support rods away from the inner ring are fixed with support rings.

[0010] Preferably, the support ring is fixed inside the sealing ring, and the length of the elastic support rod is greater than the distance between the inner ring and the support ring.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] The sealing ring located inside the sealing groove is compressed by the pressure between the sealing cap and the mixing tank when the sealing cap is closed. At the same time, the elastic inner support ring and the reinforcing spring sheet press the sealing ring outward from the inside of the sealing ring, so that the sealing ring fits tightly against the inner wall of the mixing tank and the sealing cap. This ensures that the sealing performance will not be reduced due to elastic failure during the repeated compression and recovery of the sealing ring, thus ensuring the sealing shape of the high-efficiency mixing tank.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] like Figure 1 and Figure 3As shown, a sealing structure for a high-efficiency mixing tank used in a rubber manufacturing plant includes a mixing tank 1 and a sealing cover 2. The top of the mixing tank 1 is provided with a sealing groove 3. A sealing ring 4 is provided between the mixing tank 1 and the sealing cover 2. The outer side of the bottom end of the sealing ring 4 is fixed to the inner wall of the mixing tank 1, and the sealing ring 4 is snapped into the inner side of the sealing groove 3. An elastic inner support ring 6 is installed on the inner side of the sealing ring 4. The cross-section of the elastic inner support ring 6 is U-shaped, and multiple sets of elastic support members are fixed in a ring array inside the elastic inner support ring 6. The elastic support members include multiple reinforcing springs 7. When the sealing cover 2 is closed, the compression between it and the mixing tank 1 compresses the sealing ring 4 located inside the sealing groove 3. At the same time, the elastic inner support ring 6 and the reinforcing springs 7 squeeze the sealing ring 4 outward from the inside of the sealing ring 4, so that the sealing ring 4 tightly fits the inner wall of the mixing tank 1 and the sealing cover 2, thereby achieving the sealing of the high-efficiency mixing tank.

[0019] The reinforcing spring 7 is V-shaped and made of spring steel. The reinforcing spring 7 increases the elasticity of the inner support ring 6, so that the inner support ring 6 can continuously support the sealing ring 4 from the inside.

[0020] As a preferred technical solution in this embodiment, such as Figure 1 and Figure 2 As shown, two internal reinforcing rings 5 ​​are fixed inside the sealing ring 4. The internal reinforcing ring 5 includes an inner ring 51. A stirring shaft hole is provided through the center of the sealing cover 2. The inner diameter of the inner ring 51 is larger than the diameter of the stirring shaft hole, which ensures that the stirring shaft can be installed smoothly and that the stirring shaft will not contact the internal reinforcing ring 5 when it is running.

[0021] Multiple elastic support rods 52 are distributed in a ring array on the outer surface of the inner ring 51. A support ring 53 is fixed to the end of the elastic support rod 52 away from the inner ring 51. The support ring 53 is fixed inside the sealing ring 4, and the length of the elastic support rod 52 is greater than the distance between the inner ring 51 and the support ring 53. The elastic support rod 52 applies pressure to the support ring 53 from the inside of the support ring 53, pointing towards the sealing ring 4, so that the sealing ring 4 is tightly attached to the inner surface of the mixing tank 1 and the sealing cover 2.

[0022] Working Principle: When using a high-efficiency mixing tank to mix adhesive products, the raw materials are first added into the mixing tank 1. Then, the sealing cap 2 is closed to the mixing tank 1. After the sealing cap 2 is closed, it compresses the sealing ring 4 inside the sealing groove 3. At this time, the elastic inner support ring 6 and reinforcing spring 7 inside the sealing ring 4 will elastically deform due to the compression of the sealing ring 4 by the sealing cap 2. The deformed elastic inner support ring 6 and reinforcing spring 7 apply a force to the sealing ring 4 pointing towards the mixing tank 1 and the inner wall of the sealing groove 3. At the same time, the elastic support rod 52 applies pressure to the support ring 53 from inside the support ring 53, pointing towards the sealing ring 4. This makes the sealing ring 4 tightly fit the inner surface of the mixing tank 1 and the sealing cap 2. The elastic inner support ring 6, reinforcing spring 7, and inner reinforcing ring 5 provide internal support for the sealing ring 4, thereby achieving the sealing of the high-efficiency mixing tank by the sealing ring 4. It also ensures that the sealing performance of the sealing ring 4 will not decrease due to elastic failure during repeated compression and recovery, thus ensuring the sealing shape of the high-efficiency mixing tank.

[0023] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
