Description

Technical Field

[0001] This utility model relates to the field of mixer flange technology, specifically a high-precision mixer transmission flange. Background Technology

[0002] The drive flange is mainly used to transmit the torque generated by the motor or other power source to the mixing shaft of the mixer. It acts like a "bridge" to ensure that power can be efficiently transmitted from the drive unit to the mixing components, allowing the mixing paddle to rotate normally and thus achieving the mixing operation of materials.

[0003] The existing mixer drive flanges are under constant vibration, which can cause the bolts between the two flanges to loosen. This makes it difficult to ensure the coaxiality between the flanges, bushings, and mixing shaft. Long-term operation can easily lead to vibration and uneven loading, resulting in accelerated wear of the equipment. Furthermore, the sealing rings inside the flanges suffer from material wear due to long-term friction, which reduces their sealing performance. They are also prone to hardening or softening due to temperature and media erosion, shortening their service life and causing permanent deformation, thus affecting the sealing effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-precision mixer transmission flange, which has advantages such as high accuracy and solves the problems mentioned in the background technology.

[0005] To achieve the aforementioned high precision, this utility model provides the following technical solution: a high-precision mixer transmission flange, comprising a first flange body and a second flange body, both the first flange body and the second flange body being made of high-strength alloy steel, and connecting sleeves being installed at the outer ends of both the first flange body and the second flange body.

[0006] The front wall of the first flange body is provided with four countersunk bolt holes, and each countersunk bolt hole is provided with an expansion bolt. The outer wall of the first flange body is provided with four connecting rods, each of which is provided with a carbon steel bolt in the middle. Each of the four carbon steel bolts is threaded with a nut at its rear end.

[0007] As a further improvement of this utility model: the front end of the connecting sleeve is provided with an annular groove, the inside of the annular groove is provided with a second sealing ring, and the connection between the first flange body and the second flange body is provided with a first sealing ring. The first sealing ring and the second sealing ring can improve the sealing performance of the connection.

[0008] As a further improvement of this utility model, both the first sealing ring and the second sealing ring are provided with a fluoroplastic layer on their outer surface. The fluoroplastic layer can resist the corrosion of chemical media and improve the service life of the first sealing ring and the second sealing ring.

[0009] As a further improvement of this utility model: the inner layer of the fluoroplastic layer is provided with an elastic layer, which is made of fluororubber, thereby improving the elasticity of the first sealing ring and the second sealing ring and avoiding damage caused by long-term compression.

[0010] As a further improvement of this utility model, the inner layer of the elastic layer is provided with a ceramic coating, which can resist friction and wear and improve the sealing performance.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, four expansion bolts are screwed into the countersunk bolt holes using a tool to fix the first flange body and the second flange body. Then, four carbon steel bolts are screwed into the connecting rod, and four nuts are tightened to achieve secondary tightening of the two first flange bodies and the second flange body. This avoids the first flange body and the second flange body from shifting due to vibration, thereby improving accuracy and ensuring the coaxiality between the flange, the bushing, and the stirring shaft.

[0013] 2. In this utility model, the fluoroplastic layer can resist the corrosion of chemical media, which improves the service life of the first sealing ring and the second sealing ring. The elastic layer is made of fluororubber, which improves the elasticity of the first sealing ring and the second sealing ring and avoids damage caused by long-term compression. The ceramic coating can resist friction and wear, improve the sealing performance, and prevent deformation. Attached Figure Description
