Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belt cleaners, in particular to a secondary alloy cleaner for the working surface of a conveyor belt. Background Art

[0002] During the process of a conveyor belt transporting materials, due to the characteristics of the transported materials, there is inevitably a bonding problem with the surface of the conveyor belt. If the materials on the surface of the conveyor belt cannot be efficiently cleaned, it will definitely cause the materials to adhere and wear on the rollers and idlers, reducing the service life of the conveyor belt, rollers, and idlers; the adhesion and caking on the conveyor line will also cause the conveyor belt to deviate; the adhered materials will cause spillage in the return section of the conveyor, resulting in material waste and direct economic cost losses, causing environmental pollution problems, increasing the labor intensity of on-site workers, and having an adverse impact on environmental protection and civilized production. With the improvement of the enterprise's requirements for production efficiency, the research and development of excellent cleaning products for conveyor belt materials is an important guarantee for conveying operations.

[0003] Defects and deficiencies of the prior art:

[0004] With the improvement of the environmental protection requirements of the environmental protection department for enterprises transporting materials, efficient cleaning of the conveying working conditions is a prerequisite for normal production operations. The commonly used cleaning product structures on the market are of the following types:

[0005] 1. Using a self-made fabric old belt for cleaning the conveyor belt surface. Due to the performance of the rubber material, it can only be applied to the working condition environment with a belt speed lower than 3 m / s. If the belt speed increases significantly, the friction temperature with the conveyor belt rises, causing the rubber performance to change, easily resulting in rubber carbonization and forming hard particles, which will cause serious damage to the belt. The old belt cleaning product has a simple structure, fast rubber wear, and can only be adjusted and replaced frequently by workers, with a large labor intensity. If the adjustment is not timely, the cleaning effect will be worse.

[0006] 2. Polyurethane scraper cleaners, mostly with a single compensation mechanism for the cleaning frame base, have an unreasonable compensation mechanism design and cannot achieve a good automatic compensation function. Due to the performance of the scraper material, they are mostly applicable to working conditions within 4.5 m / s, with limited application scope of the product.

[0007] 3. Conventional secondary alloy blade cleaners have a large product design structure, complicated installation and maintenance, and for the working condition environment with a narrow on-site space, there are problems such as short service life, limited by on-site installation, and inability to achieve good cleaning effect requirements.

[0008] 4. For the case of conveying by the load belt conveyor, the traditional secondary alloy cleaner has a certain cleaning effect with a single-row scraper under normal working conditions. However, when operating under load and requiring efficient composite cleaning, there are very large deficiencies and limitations. Moreover, there are other risks brought by the alloy cleaning scraper, and its cleaning effect is extremely poor, unable to achieve the cleaning function. Summary of the Invention
