Description

Technical Field

[0001] The utility model belongs to the technical field of drying equipment, and in particular relates to a friction belt for a drying unloading belt machine. Background Art

[0002] As an advanced industrial machine, the drying conveyor belt is specifically designed for both conveying and drying materials simultaneously. It cleverly utilizes the belt as a carrier for the material. As the material moves along the belt, specific conditions promote the evaporation of moisture from the material, achieving the drying goal. This technology has a wide range of applications, encompassing industries such as food, chemicals, and building materials. It effectively handles granular, powdered, and even flaky materials, significantly improving their storage stability and subsequent processing performance.

[0003] In practice, the conveyor belt's speed and drying conditions must be precisely controlled to ensure uniform drying of the material and meet the high standards of industrial production for material handling efficiency and quality. This precise control makes the conveyor belt an indispensable component of modern production lines, improving production efficiency while ensuring the quality of the final product.

[0004] However, even such sophisticated equipment can face challenges in certain production environments. For example, in high-humidity workshops or when handling materials with a high moisture content, the dryer conveyor belt may become damp. This condition typically occurs because the belt is not completely protected from moisture during transportation or is not adequately dried after cleaning. Once damp, material can adhere to the belt, hindering smooth material transfer and reducing production efficiency. In severe cases, it can even cause belt blockage, forcing the production line to temporarily shut down.

[0005] Furthermore, prolonged exposure to humidity can accelerate the aging of the belt material, altering its physical properties and reducing its strength and toughness. This shortens the belt's service life and increases maintenance and replacement costs. Therefore, to ensure the proper operation of drying and unloading belts, humidity control at the production site is crucial. Companies should implement measures such as installing dehumidification equipment to maintain an appropriate humidity level in the workshop; regularly inspecting the belt's dryness and thoroughly drying it when necessary; and pre-treating the material to minimize its initial moisture content to prevent and mitigate the adverse effects of moisture. Utility Model Content

[0006] In view of this, the utility model provides a friction belt for a drying and unloading belt machine, which can solve the problem that the material becomes damp again during transportation by the traditional drying and unloading machine, and improve the drying effect.

[0007] The utility model is achieved in this way:

[0008] The utility model provides a friction belt for a drying unloading belt machine, comprising a conveyor belt, wherein the conveyor belt comprises an outer belt and an inner belt, the inner belt is wrapped inside the outer belt, and a hollow structure is formed between the outer belt and the inner belt through a supporting component, and the hollow structure is used for ventilation and drying, and a dividing belt for separating materials is also provided above the outer belt, and the dividing belt is evenly distributed above the conveyor belt.

[0009] On the basis of the above technical solution, the friction belt for a drying and unloading belt conveyor of the utility model can also be improved as follows:

[0010] Wherein, the support component is a cylindrical tube, which is fixedly connected to the outer belt and the inner belt, and the thickness of the top and bottom of the support component is greater than the thickness of the middle of the support component.

[0011] The outer belt has ventilation holes on its surface.

[0012] Furthermore, the separation belt includes a first end face and a second end face, the first end face is arc-shaped and perpendicular to the surface of the outer belt, and the second end face is an arc-shaped segment for dividing materials.

[0013] Furthermore, the cross section of the second end face is 1 / 4 circle, and the second end face is tangent to the outer belt and tangent to the first end face.

[0014] The beneficial effects of adopting the above-mentioned improvement scheme are: First, the 1 / 4 circle geometry makes the contact surface between the dividing belt and the material softer, effectively reducing damage to the material, especially for those fragile or sensitive materials. This design can significantly improve the integrity of the material and reduce waste in the production process; secondly, the tangent design of the second end face and the outer belt ensures the formation of a stable contact point between the dividing belt and the belt, which not only helps to improve the positioning accuracy of the material on the belt, but also reduces the lateral displacement of the material during movement, thereby enhancing the stability and reliability of material transmission. At the same time, due to the reduction of the contact area between the dividing strip and the belt, the friction is moderately controlled, which can not only ensure that the material is properly guided, but also avoid energy loss caused by excessive friction, thereby improving the working efficiency of the system; furthermore, the tangent design with the first end face forms a natural material guide groove. When the material falls on the dividing strip, this guide groove can guide the material to move along the predetermined path, avoiding the material from being scattered or accumulated on the belt at will, thereby ensuring the uniform distribution of the material, which is crucial for production processes that require precise metering or uniform mixing; in addition, this design also takes into account the fluidity of the material. The 1 / 4 circle cross-section helps to reduce the retention of material at the edge of the dividing strip and speed up the flow of material. Especially when dealing with materials with high viscosity, it can effectively prevent the adhesion and accumulation of materials, improve the self-cleaning ability of the belt, reduce the downtime for cleaning, and thus improve the operating efficiency and production capacity of the entire production line.

[0015] In summary, by designing the second end face of the dividing belt to have a 1 / 4 circle cross-section and making it tangent to the outer belt and the first end face, not only the accuracy and efficiency of material handling are improved, but also the stability and durability of the system are enhanced. This is an important innovation in modern material handling technology.

[0016] Furthermore, the second end face includes a first curved surface and a second curved surface, the centers of the first curved surface and the second curved surface are located on both sides of the second end face, the first curved surface is tangent to the second curved surface, the first curved surface is tangent to the outer belt, and the tangent line at the junction of the second curved surface and the second end face is perpendicular to the second end face.

[0017] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: First, this special combination of curved surfaces can more effectively guide and control the flow direction of the material. The large radius of the first curved surface provides a smooth transition area for the material, allowing the material to slide smoothly on the separation belt, avoiding jumping or splashing due to sudden changes in direction, helping to maintain the uniform distribution of the material and improving the accuracy and efficiency of material processing; secondly, the sharpness of the second curved surface with a smaller radius is effectively controlled when it comes into contact with the material, which is especially critical when handling fragile or sensitive materials. Compared with traditional right-angle or sharp edge designs, the rounded transition of the second curved surface significantly reduces the physical impact on the material and reduces the possible breakage and wear of the material during the separation process, which is crucial to maintaining the integrity and quality of the material; thirdly, the first curved surface is tangent to the outer belt, and the tangent line at the junction of the second curved surface and the second end surface is perpendicular to the second end surface. Together, they create a contact interface that can effectively separate the material without causing additional pressure on the material. This design ensures that materials are separated while avoiding deformation or breakage caused by excessive local pressure. This is particularly true when processing flaky, granular, or fibrous materials, significantly reducing material damage and improving production yields. Furthermore, this geometric design helps reduce material retention time on the separator belt, promoting rapid material flow, which is crucial for improving production efficiency and reducing material blockages. The combination of the first and second curved surfaces creates a natural material guide path on the belt, effectively preventing material from adhering to the separator belt even when handling highly humid or sticky materials, maintaining the belt in good operating condition and reducing the need for maintenance.

[0018] Furthermore, the radius of the first arc-shaped surface is greater than the radius of the second arc-shaped surface.

[0019] Furthermore, the surface of the outer belt is rough, and the surface of the dividing belt is smooth.

[0020] Furthermore, the height of the dividing belt is less than twice the height of the conveyor belt.

[0021] Furthermore, the width of the dividing strip is 1 / 2 or 1 times the width of the conveyor belt.

[0022] Furthermore, the outer belt is made of rubber or polyurethane.

[0023] Compared with the prior art, the friction belt for a drying and unloading belt conveyor provided by the utility model has the following beneficial effects:

[0024] Improved material handling accuracy and efficiency: The special geometry of the separator, especially the design of the second end surface consisting of the first and second curved surfaces, effectively controls the flow direction and speed of the material, reduces material jumping and splashing, and ensures uniform material distribution and accurate metering, which is crucial for production processes that require strict control of material ratios;

[0025] Material Protection and Integrity: The combination of a large-radius first curved surface and a smaller-radius second curved surface, as well as the gentle contact with the outer belt, significantly reduces the risk of physical damage to materials during transportation. This design can significantly improve material integrity, reduce waste during production, and ensure product quality, especially for fragile or sensitive materials.

[0026] Enhanced system stability and durability: The stable contact point design between the separator belt and the outer belt, as well as the moderately controlled friction, not only ensures reliable material guidance, but also reduces unnecessary energy loss and improves system efficiency. At the same time, this design also enhances the self-cleaning ability of the belt, reduces maintenance requirements, and extends the service life of the equipment.

[0027] Material flowability and anti-blocking performance: The second end surface of the 1 / 4 circular cross-section helps reduce the retention of materials at the edge of the dividing zone, speeding up the flow of materials. Especially when processing highly viscous or high-humidity materials, it can effectively prevent material adhesion and accumulation, reduce the number of shutdowns for cleaning, and improve the overall operating efficiency and production capacity of the production line;

[0028] Adaptability and flexibility: The reasonable setting of the height and width of the dividing belt, as well as the selection of the outer belt material (such as rubber or polyurethane), enable the friction belt of the utility model to adapt to the characteristics of various materials and different production environment requirements, thereby improving the adaptability and flexibility of the equipment;

[0029] Ventilation and drying efficiency: The hollow structure and the vent holes on the outer belt enhance the ventilation and drying effects. For materials that need to be dried during transportation, such as wet sand and clay, they can effectively prevent material agglomeration and improve the efficiency and quality of material handling.

[0030] In summary, the friction belt for the drying unloading belt conveyor of the utility model significantly improves the accuracy, efficiency and safety of material handling through its innovative structural design and detail optimization, while also enhancing the stability and durability of the system. It is an important technological advancement in the field of modern material handling. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] Specifically, the principle of the present utility model is:

[0056] Ventilation and Drying Principle: The hollow structure of the inner and outer double belts and support components creates ventilation channels. When hot or dry air flows through these channels, it accelerates the evaporation of moisture on the material surface, achieving a drying effect. This design utilizes the principles of aerodynamics to ensure smooth air flow and improve drying efficiency.

[0057] Material Separation and Guidance Principle: The separator strip is introduced to evenly distribute the material along the belt, preventing material concentration or accumulation that could affect subsequent processing or metering. The separator strip's unique geometry, such as the curved design of its first and second end faces, guides the material smoothly along the length of the belt, minimizing material skipping and splashing, and maintaining uniform material distribution. The quarter-circular cross-section of the second end face, tangent to both the outer belt and the first end face, forms a smooth material guide trough, ensuring material movement along the pre-set path, minimizing lateral displacement, and improving material transmission stability and positioning accuracy.

[0058] Material protection and fluidity principle: The coordinated use of the first curved surface and the second curved surface, especially the large radius of the first curved surface and the small radius design of the second curved surface, can provide conditions for the material to slide smoothly on the dividing strip, avoiding physical damage to the material, while maintaining the fluidity of the material and reducing adhesion and accumulation; when the material passes through the dividing strip, it will be subject to the smooth transition of the first curved surface, reducing jumping and splashing, while the sharpness of the second curved surface is effectively controlled to avoid unnecessary pressure on the material and ensure the integrity and quality of the material.

[0059] Friction and wear control principle: The rough design of the outer belt surface increases the friction with the material, which helps to ensure the stable transmission of the material, while the smooth surface of the separator belt reduces the friction between the material and the separator belt, avoids excessive wear and extends the service life of the equipment; by controlling the height and width of the separator belt, as well as the contact area between the separator belt and the material, the friction can be appropriately adjusted to ensure the guidance and separation of the material while reducing unnecessary energy loss.

[0060] Material selection principle: The choice of outer belt material, such as rubber or polyurethane, is based on its excellent wear resistance, temperature resistance and chemical stability. It can adapt to high temperature, humid or chemical-containing production environments, ensuring the long-term stable operation of the belt.

[0061] In summary, the utility model achieves high precision, high efficiency and low loss in material processing by cleverly combining the principles of ventilation drying, material separation, material protection and fluidity control, friction and wear control, and material selection. It is an important innovation in material handling and drying technology in modern industrial production.

[0062] When in use, the material falls on the conveyor belt 1, and the dividing belt 2 divides the material into multiple units, reducing the area of the wet material affecting the surrounding materials; the fan or desiccant in the conveyor belt 1 further dries the material on the outer belt 11.
