Description

Technical Field

[0001] The utility model relates to the technical field of sealing strips, in particular to a sealing strip for a sulfur filter. Background Art

[0002] Most of my country's natural ores, especially zinc ore and phosphate ore, contain corresponding minerals and are accompanied by sulfur ore. Therefore, extracting sulfur from tailings is an important step for major smelters. Sulfur filter is the key equipment for sulfur extraction. Sulfur filter is the equipment used for liquid sulfur filtration in industry. In the sulfur melting section of sulfur acid production, after filtering the liquid sulfur, there is a large amount of slag in the filter that needs to be cleaned. Liquid sulfur will produce rust, sulfur slag and other debris, which may cause the filter to be blocked. Therefore, the design of the filter is very important, and the sealing strip used in the sulfur filter is the prerequisite for ensuring the normal operation of the sulfur filter.

[0003] The traditional sealing strip is square and installed in the sealing groove of the sulfur filter. When the sulfur filter is working, the pressure will reach 6MPa and the temperature will reach 200C. The service life of the traditional sealing strip is very short and it is very inconvenient to replace it. The temperature on site is too high. It is easy to cause safety accidents if it relies entirely on manual replacement. Therefore, the sulfur filter sealing strip is proposed to solve the above-mentioned problems. Utility Model Content

Since the pressure of the sulfur filter will reach 6MPa and the temperature will reach 200C when the sulfur filter is working, the service life of the traditional sealing strip is very short and it is very inconvenient to replace it. The temperature on site is too high, and it is easy to cause safety accidents if it relies entirely on manual replacement.

[0005] To achieve the above object, the utility model provides the following technical solution: a sulfur filter sealing strip, comprising a rubber sealing body, on which a dustproof lip, an inner sealing lip and an outer sealing lip are sequentially arranged, and a groove is provided inside the rubber sealing body;

[0006] The rubber sealing body comprises an inner layer, a core body and an outer layer located inside the rubber sealing body;

[0007] The outer layer comprises a composite layer installed on the outer surface of the core, a wear-resistant layer installed on the outer surface of the composite layer, an antibacterial layer installed on the outer surface of the wear-resistant layer, and a high-temperature resistant layer installed on the inner wall of the inner layer.

[0008] Preferably, the rubber sealing body is composed of an inner layer, a core body, an outer layer and a high temperature resistant layer.

[0009] Preferably, the inner layer is made of natural rubber and has a thickness of 0.5 cm.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figure 1-3 The sulfur filter sealing strip in this embodiment includes a rubber sealing body 1, on which a dustproof lip 3, an inner sealing lip 4 and an outer sealing lip 2 are sequentially arranged, and a groove 5 is opened inside the rubber sealing body 1.

[0024] It should be noted that most of my country's natural ores, especially zinc ore and phosphate ore, contain corresponding minerals and are accompanied by sulfur ore. Therefore, extracting sulfur from tailings is an important process for major smelters. Sulfur filter is a key equipment for sulfur extraction. The sealing strip used in the sulfur filter is a prerequisite for ensuring the normal operation of the sulfur filter. The rubber sealing body 1, dustproof lip 3, inner sealing lip 4, outer sealing lip 2 and groove 5 arranged above can form a rubber strip with high temperature resistance, high elasticity and wear resistance.

[0025] A dustproof lip 3, an inner sealing lip 4 and an outer sealing lip 2 are arranged in sequence on the rubber sealing body 1. The dustproof lip 3 is mainly used to prevent external dust, dirt, etc. from entering the sealing body and protect the inner sealing lip from damage; the inner sealing lip 4 is the part that directly contacts the sealed medium and is responsible for the main sealing task. It relies on the preload force filled in the sealing cavity and its lip edge close to the surface of the sealing cavity to prevent leakage channels and obtain a sealing effect; the outer sealing lip 2 is mainly used to enhance the sealing effect, provide additional protection, and ensure the stability and reliability of the entire sealing system.

[0026] The rubber sealing body 1 includes an inner layer 101, a core body 102 and an outer layer 103 located inside the rubber sealing body 1. The inner layer 101, the core body 102 and the outer layer 103 form the rubber sealing body 1, so as to avoid the rubber sealing body 1 being made of a whole material. The rubber sealing body 1 is made in a circular shape. Due to its own elasticity, the circular rubber sealing body 1 can produce a greater deformation when the pressure increases.

It has good wear resistance and fatigue resistance, thereby extending the service life of the rubber seal body 1.

Nitrile rubber has excellent wear resistance and can work under high friction and high pressure, reducing the possibility of wear and damage to the seal; the antibacterial layer 1033 uses nano-scale silver ions with a thickness of 0.3CM. Nano-scale silver ions can effectively inhibit the growth of bacteria and achieve excellent antibacterial effects.

[0032] The composite layer 1031 is made of composite material with a thickness of 0.3CM. The composite layer 1031 is made of composite material. The rubber sealing ring made of composite material combines the advantages of multiple materials and has excellent performance. It not only has the elasticity of rubber, but also has the high strength and wear resistance of metal.

[0033] The high temperature resistant layer 104 is made of high temperature resistant material and has a thickness of 0.3CM. Its main purpose is to increase the operating temperature range of the rubber seal 1 so that it can maintain good sealing performance in a high temperature environment, avoid being too hot, and improve the safety of operators.

[0034] In summary, the sulfur filter sealing strip is provided with a rubber sealing body 1, on which a dustproof lip 3, an inner sealing lip 4 and an outer sealing lip 2 are sequentially provided.
