Description

Technical Field

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

[0002] In the process of conveying materials with conveyor belts, the skeleton material of conveyor belts is divided into steel wire core conveyor belts, fabric core conveyor belts and PVC / PVG skeleton conveyor belts according to different working conditions. Among them, the connection process of PVC / PVG conveyor belts is mostly a multi-group mechanical buckle connection method. The cleaning difficulty of the conveyor belt surface with multiple sets of mechanical buckles is higher than that of the vulcanized connection conveyor belt, and the adhesion problem between the conveyed materials and the conveyor belt surface and the joint area increases. If the materials on the surface of the PVC / PVG mechanical buckle conveyor belt cannot be effectively cleaned, the materials will definitely adhere to the rollers and rollers, wear the conveyor belt surface, and reduce the service life of the conveyor belts, rollers, and rollers; adhesion and agglomeration on the conveyor line will also cause the conveyor belt to deviate; the adhered materials will cause material spillage in the return section of the transmission, resulting in material waste and direct economic cost losses, environmental pollution problems, and increased labor intensity of on-site workers, which will have an adverse impact on environmental protection and civilized production. Since mechanical buckle conveyor belts have higher requirements for the impact resistance of the scraper blades, and as companies increase their requirements for on-site cleanliness, the development of excellent sweeping (cleaning) products for the collection of materials on PVC / PVG mechanical buckle conveyor belts is also an important guarantee for conveying operations.

[0003] Defects and shortcomings of the existing technology:

[0004] As the national environmental protection department has increased its environmental protection requirements for enterprises that use PVC / PVG mechanical buckles to transport materials at well sites, cleanliness of the conveying conditions is a prerequisite for normal production operations. Currently, the commonly used cleaning product structures for PVC / PVG mechanical buckle conveyor belts on the market include the following types:

[0005] 1. Use old belts with self-made fabric core to clean the surface of PVC / PVG mechanical buckle conveyor belts. Due to the properties of rubber materials, it can only be used in working conditions where the belt speed is less than 3m / s. If the belt speed increases significantly, the friction temperature with the conveyor belt will increase, causing the rubber properties to change, which can easily cause rubber carbonization and form hard particles, causing serious damage to the belt. The old belt cleaning product has a simple structure and the rubber wears quickly. It can only be adjusted and replaced frequently by workers, which is labor-intensive. If the adjustment is not timely, the cleaning effect will be worse.

[0006] 2. Polyurethane scraper cleaners mostly use a single compensation mechanism on the base of the cleaning frame. The compensation mechanism is not designed reasonably and cannot achieve a good automatic compensation function. Due to the performance of the scraper material, the applicable working conditions are mostly within 4.5m / s, and the product application range is limited.

[0007] 3. The product design structure of conventional alloy scraper cleaners is designed for PVC / PVG mechanical buckle conveyor belts and high-efficiency working environments. However, they have the following problems: short service life, poor impact resistance of the scraper blades, easy breakage, cleaning effect that cannot meet working conditions requirements, and the risk of scratching the conveyor belt.

Specific embodiments

[0066] like Figures 1 to 7 As shown, a device for cleaning the working surface of a conveyor belt includes all the contents of Example 3. In addition, the purpose is to address the problems of poor cleaning effect, short service life, and frequent adjustments by workers of the current PVC / PVG mechanical buckle conveyor belt working surface cleaning products. A device for cleaning the working surface of a conveyor belt specifically for PVC / PVG mechanical buckle is developed to meet the requirements of reliable cleaning and automatic compensation functions of PVC / PVG mechanical buckle conveyor belt working conditions.

[0067] Tiptop HM-U13-B mechanical buckle alloy cleaner is an impact-resistant secondary alloy cleaner. It is a secondary cleaning product installed behind the tangent point of the drum wrap angle. It is particularly suitable for cleaning the belt surface under impact conditions such as PVC / PVG belt mechanical buckles. Its structural design is novel, simple and reasonable, and easy to install and maintain. The middle bracket, the mounting adjustment seats on both sides and the special scraper assembly are all independent units, making it easy and simple to replace each unit module. The segmented high-wear-resistant and impact-resistant alloy and elastic modules located on the upper part of the scraper assembly work independently. For mechanical buckle PVC / PVG type conveyor belt systems, its excellent special scraper and automatic compensation mechanism combination unit can ensure the best contact state with the conveyor belt surface, achieve efficient and highly applicable cleaning effects, and has the characteristics of impact resistance, high wear resistance, corrosion resistance, easy adjustment, etc., and also has the advantages of long service life and high reliability.

[0068] Tiptop HM-U13-B mechanical buckle secondary alloy cleaner consists of 6 types of product components, including left and right side mounting adjustment seat components, HM-U13-B left, middle and right scraper components, scraper bracket components, etc. The scraper bracket component consists of three types of components: the middle bracket component, the extension pipe component, and the two side connecting plates.

[0069] The assembly sequence is as follows: the left, middle and right scraper blade assemblies of HM-U13-B are respectively assembled on the scraper blade bracket assembly, and the left and right side mounting adjustment seat assemblies are assembled on the extension tube component of the scraper blade bracket assembly.

[0070] The left, middle and right scraper blade assemblies of HM-U13-B are in contact with the working surface of the PVC / PVG belt mechanical buckle conveyor belt. As the main cleaning material components, in order to meet the working conditions of the mechanical buckle PVC / PVG type conveyor belt, the thickness of the alloy sheet of a single alloy assembly is selected to be thickened and widened impact-resistant and wear-resistant tungsten carbide alloy sheet, and the length of a single scraper blade assembly is 145mm. The HM-U13-B scraper blade assembly is distributed independently in sections to ensure the effective cleaning function of each scraper blade assembly in the process of cleaning the surface of the PVC / PVG belt mechanical buckle conveyor belt. In order to achieve the best cleaning function, the alloy sheet of the middle scraper blade assembly is two 72.5mm long right-angle alloy sheets. The left and right side scraper blade assemblies are on both sides of the cleaner. In order to avoid affecting the edge of the PVC / PVG belt mechanical buckle conveyor belt, the left and right scraper blade assemblies are composed of a right-angle alloy sheet and a rounded alloy sheet. The elastic module in the scraper assembly serves as an automatic elastic compensation unit, providing independent elastic compensation functions for independent scraper assemblies, ensuring the impact resistance automatic compensation effect under good cleaning of PVC / PVG belt mechanical buckle conveyor belts. The PE plate guide plates on both sides are installed on the lateral sides of the scraper assembly, so that the cleaned materials can be discharged smoothly without accumulation.

[0071] The scraper bracket assembly is the main part of the cleaning frame, and is composed of three types of components: the middle bracket component, the extension pipe component, and the two side connecting plates. This enables the left, middle, and right scraper assemblies to rotate and support on the left and right side mounting adjustment seat components. Its strength design is reliable. The extension pipe component of the scraper bracket assembly is designed into three specifications through force analysis, B500-B800 for small diameter specifications, B1000-B1400 for medium diameter specifications, and B1600-B2400 for large diameter specifications. The two side connecting plates of the scraper bracket assembly are designed to achieve limited space cleaning installation without interfering with the function.

[0072] The left and right side mounting adjustment seat components serve as the connection support between the entire cleaner and the on-site foundation and the secondary automatic elastic compensation adjustment function. The connection method with the foundation is flexible and can be connected by welding or bolting. The stroke and specifications of the M30 trapezoidal screw on the left and right side mounting adjustment seat components are designed through force analysis. The specifications and models of the left and right side mounting adjustment seat components are developed and designed into three specifications and models according to the working conditions parameters, B500-B800 for small specifications, B1000-B1400 for medium specifications, and B1600-B2400 for large specifications. Ensure that the HM-U13-B mechanical buckle secondary alloy cleaner cleans the PVC / PVG belt mechanical buckle conveyor belt in the process of excellent cleaning effect.
