Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a de-icing device for belt conveyors. Background Technology

[0002] Belt conveyors are widely used in metallurgy, mining, and freight transportation, serving as crucial equipment for conveying bulk materials. In winter, especially in cold northern regions, the surface of the conveyor belt is prone to freezing due to the moisture content of the material or the ambient humidity, forming an ice layer. In severe cases, material can freeze solid onto the conveyor belt, causing slippage, misalignment, and even affecting the conveyor's lifespan. Current technology typically uses belt cleaners and brushes to remove the ice layer, but because frozen ice is smooth and hard, de-icing efficiency is low, resulting in unsatisfactory de-icing effects that hinder the normal operation of the belt conveyor and create safety hazards.

[0003] Therefore, this utility model proposes a de-icing device for belt conveyors to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a de-icing device for belt conveyors.

The axis connecting line of at least two of the de-icing rollers is parallel to the extension direction of the conveyor belt, and at least one of the de-icing rollers has a different axis height than the other de-icing rollers. A drive unit drives the multiple de-icing rollers to revolve around a common rotation axis, and the direction of the revolution is opposite to the running direction of the conveyor belt.

[0006] Furthermore, the de-icing assembly also includes a mounting plate, with both ends of the plurality of de-icing rollers respectively fixedly connected to the mounting plate, and the driving unit drives the plurality of de-icing rollers to rotate through the mounting plate.

[0007] Furthermore, the number of de-icing rollers is greater than or equal to three, the mounting plate is a polygonal plate, and the de-icing rollers are installed one-to-one between adjacent sides of the polygonal plate.

[0008] Furthermore, there are three de-icing rollers, and the axes of the de-icing rollers are connected to each other to form an equilateral triangle. The de-icing rollers are rotatably connected to the polygonal plate.

[0009] Furthermore, the outer surface of the pressure roller assembly and / or the de-icing roller is provided with raised ribs.

[0010] Furthermore, the outer surface of the pressure roller assembly is surrounded by a first rib segment and a second rib segment, the first rib segment and the second rib segment having different surrounding directions; the outer surface of the de-icing roller is surrounded by a third rib segment and a fourth rib segment, the third rib segment and the fourth rib segment having different surrounding directions.

[0011] Furthermore, the outer surface of the de-icing roller is provided with raised ribs, and at least one of the de-icing rollers has a rib whose circumferential direction is different from that of the other de-icing rollers.

[0012] Furthermore, the drive unit includes a coupling and a geared motor, with one end of the coupling fixedly connected to the geared motor and the other end fixedly connected to the drive shaft of the mounting plate.

[0013] Furthermore, the pressure roller assembly includes a first pressure roller and a second pressure roller, the first pressure roller forming a first contact point with the conveyor belt, the second pressure roller forming a second contact point with the conveyor belt, and the contact point between the de-icing assembly and the conveyor belt located between the first contact point and the second contact point.

[0014] Furthermore, the de-icing device for the belt conveyor also includes a collection bin, the lower part of which adopts a square funnel-shaped structure.

[0015] The beneficial effects of this utility model are: The de-icing device for belt conveyors provided by this utility model applies pressure to the conveyor belt by placing a pressure roller assembly above the conveyor belt and rolling it into contact with the inner side of the belt. The de-icing assembly is positioned below the conveyor belt and abuts against its outer side. The cooperation between the pressure roller assembly and the de-icing assembly peels off and removes the ice layer on the belt surface.

[0024] This utility model discloses a de-icing device for a belt conveyor, including a conveyor belt 100, a pressure roller assembly 200, and a de-icing assembly 300. The pressure roller assembly 200 is disposed above the conveyor belt 100 and rolls against the inner side of the conveyor belt 100. The de-icing assembly 300 is disposed below the conveyor belt 100 and abuts against the outer side of the conveyor belt 100. The de-icing assembly 300 includes a plurality of de-icing rollers 310. The axis connecting line of at least two of the de-icing rollers 310 is parallel to the extension direction of the conveyor belt 100, and at least one of the de-icing rollers 310 has a different axis height than the other de-icing rollers 310. A drive unit 400 drives the plurality of de-icing rollers 310 to revolve around a common rotation axis, and the direction of the revolution is opposite to the running direction of the conveyor belt 100.

[0025] like Figures 1 to 5As shown in the figure, the de-icing device for belt conveyors disclosed in this utility model embodiment achieves efficient removal of ice adhering to the conveyor belt 100 by setting up a pressure roller assembly 200 and a de-icing assembly 300 to work together. Specifically, the pressure roller assembly 200 is located above the conveyor belt 100 and rolls in contact with its inner side, thereby applying a certain pressure to the conveyor belt 100 during operation to ensure its tension and improve the de-icing effect; while the de-icing assembly 300 is arranged below the conveyor belt 100 and abuts against its outer side, mainly responsible for peeling and removing the ice layer on the belt surface.

[0026] Furthermore, the de-icing assembly 300 includes a plurality of de-icing rollers 310, with at least two of the de-icing rollers 310 having their axial connecting lines parallel to the extension direction of the conveyor belt 100, and at least one of the de-icing rollers 310 having an axial height different from the others. This structural design creates a height difference between the contact points of each de-icing roller 310 and the conveyor belt 100. As the de-icing rollers 310 revolve around a common rotation axis with the drive unit 400, periodically changing contact pressure and angle are formed, thereby enhancing the shearing force and peeling effect on the ice layer and effectively preventing ice residue on the conveyor belt 100. Simultaneously, since the extension direction of the axial connecting lines of at least two de-icing rollers 310 is the same as the extension direction of the conveyor belt 100, it is not necessary to provide a certain pre-tension force to the conveyor belt 100 to make it bulge during the installation of this de-icing device. Installation can be completed simply by tightly attaching the de-icing rollers 310 and the pressure roller assembly 200 to the tape. By setting the positional distribution relationship between the de-icing rollers 310, installation is time-saving, labor-saving, and maintenance-free.

[0027] Furthermore, the drive unit 400 drives multiple de-icing rollers 310 to revolve around a common axis of rotation, and this revolving direction is opposite to the running direction of the conveyor belt 100. This reverse revolving design increases the relative speed between the de-icing rollers 310 and the conveyor belt 100, increasing the number of times the ice layer is acted upon per unit time, thereby significantly improving de-icing efficiency. At the same time, the friction generated by the reverse motion also helps to break the adhesion between the ice layer and the belt, further promoting the shedding of ice.

[0028] The drive unit 400 is connected to the mounting plate 320 via a transmission mechanism (such as a coupling 410, gear set, sprocket chain, or synchronous belt), driving the entire mounting plate 320 and the de-icing rollers 310 on it to revolve around a set common axis of rotation. By centrally fixing multiple de-icing rollers 310 onto the mounting plate 320, a modular design is formed, simplifying the on-site installation process and facilitating unified debugging and subsequent replacement and maintenance.

[0029] In summary, this technical solution not only solves the problems of low efficiency, high energy consumption, and poor applicability of traditional de-icing methods, but also provides a reliable guarantee for the stable operation of belt conveyors in cold environments. The de-icing device for belt conveyors provided by this utility model effectively improves the ice removal efficiency through the coordinated operation of the pressure roller assembly 200 and the de-icing assembly 300, combined with the height difference arrangement and reverse revolution design of the de-icing roller 310. The rolling contact method between components reduces wear, extends service life, and facilitates daily maintenance and replacement.

[0030] In one embodiment of the present invention, the de-icing assembly 300 further includes a mounting plate 320, and the two ends of the plurality of de-icing rollers 310 are respectively fixedly connected to the mounting plate 320. The driving unit 400 drives the plurality of de-icing rollers 310 to rotate through the mounting plate 320.

[0031] like Figures 1 to 5 As shown, the de-icing assembly 300 also includes a mounting plate 320. Both ends of multiple de-icing rollers 310 are fixedly connected to the mounting plate 320. The drive unit 400 drives the multiple de-icing rollers 310 to revolve around a common axis of rotation via the mounting plate 320. This structural design allows the multiple de-icing rollers 310 to form a unified, interconnected de-icing module, which not only facilitates assembly, adjustment, and maintenance, enhancing the structural stability and functionality of the de-icing device, but also significantly improves its applicability and de-icing efficiency in complex environments.

[0032] Specifically, the mounting plate 320, as a key component for support and transmission, has high structural strength and good stability, effectively bearing the weight of multiple de-icing rollers 310 and the dynamic loads generated during operation. Multiple de-icing rollers 310 are evenly or asymmetrically distributed on the mounting plate 320, arranged according to the height difference requirements in the aforementioned technical solution. This ensures that each de-icing roller 310 forms different contact angles and pressures with the outer surface of the conveyor belt 100, avoiding problems such as poor synchronization and uneven force distribution that may occur when driving a single de-icing roller 310, thus improving the stability and reliability of the overall transmission system.

[0033] Furthermore, the mounting plate 320 may be provided with multiple mounting holes so that the de-icing roller 310 can be installed at different positions through the mounting holes, so that the installation height of the de-icing roller 310 relative to the mounting plate 320 and the conveyor housing can be adjusted, thereby adapting to conveyor belts 100 of different thicknesses and tensions, and improving the versatility and on-site adaptability of the device.

[0034] In one embodiment of this utility model, the number of the de-icing rollers 310 is greater than or equal to 3, the mounting plate 320 is a polygonal plate, and the de-icing rollers 310 are installed one-to-one between adjacent sides of the polygonal plate.

[0035] By using a polygonal mounting plate 320 to rationally distribute multiple de-icing rollers 310 between the corners, installation space is effectively saved, making the entire de-icing assembly 300 more compact and facilitating efficient de-icing operations within a limited space. This also further enhances the overall structural stability and functionality of the de-icing assembly 300. Specifically, the polygonal mounting plate 320 can be a regular or polygonal structure such as a triangle, quadrilateral, or hexagon, and its shape should be matched to the width of the conveyor belt 100 and the de-icing requirements. Each de-icing roller 310 is positioned between two adjacent sides of the polygonal plate, forming a de-icing unit distributed around a common axis of rotation. This arrangement ensures that each de-icing roller 310 maintains a stable geometric relationship as it revolves with the mounting plate 320, guaranteeing the continuity and uniformity of the de-icing process.

[0036] In addition, this embodiment adopts a coordinated arrangement of polygonal mounting plate 320 and multiple de-icing rollers 310. Due to the good mechanical properties of the polygonal structure, it can effectively disperse and transmit the stress generated during operation, improve the rigidity and deformation resistance of the mounting plate 320, and thus enhance the overall structural strength of the de-icing assembly 300.

[0037] In one embodiment of this utility model, there are three de-icing rollers 310, and the axis connecting lines of the de-icing rollers 310 are connected to each other to form an equilateral triangle. The de-icing rollers 310 are rotatably connected to the polygonal plate.

[0038] like Figure 3 As shown, there are three de-icing rollers 310, whose axes are connected to form an equilateral triangle structure. Each de-icing roller 310 is rotatably connected to the polygonal mounting plate 320. This specific geometric layout not only enhances the overall structural symmetry and operational stability of the device but also further optimizes the distribution of de-icing forces, improving de-icing efficiency. Specifically, the three de-icing rollers 310 are arranged on the polygonal mounting plate 320 at the vertices of the equilateral triangle and are connected to the mounting plate 320 via bearings or other rotating connectors to ensure that they can only revolve around the mounting plate 320 and also rotate freely around their own axes as the conveyor belt 100 moves. This equilateral triangle layout ensures that the forces among the three rollers are evenly distributed and rationally balanced, forming a stable three-point contact area during the operation of the conveyor belt 100, thereby improving the continuity and consistency of the de-icing process.

[0039] Furthermore, when the drive unit 400 drives the mounting plate 320 and the de-icing rollers 310 on it to revolve around the common axis of rotation, since the three de-icing rollers 310 are distributed in an equilateral triangle, their contact points with the conveyor belt 100 will change periodically. Combined with the reverse rotation design, the shearing and peeling forces on different parts of the ice layer can be effectively enhanced, avoiding the phenomenon of incomplete local de-icing.

[0040] In one embodiment of the present invention, the outer surface of the pressure roller assembly 200 and / or the de-icing roller 310 is provided with raised ribs 500.

[0041] like Figures 1 to 2 As shown, by setting ribs 500 with a certain height and distribution pattern on the outer surface of the pressure roller assembly 200 and / or the de-icing roller 310, the contact performance and effect between them and the conveyor belt 100 are further enhanced, thereby improving the working efficiency and adaptability of the entire de-icing device. Specifically, the rib structure 500 can effectively increase the friction coefficient between the pressure roller assembly 200, the de-icing roller 310 and the conveyor belt 100, preventing slippage; at the same time, during the de-icing process, it can also break the ice layer structure through the local stress concentration effect, improving the ice-breaking efficiency. The raised rib structure 500 forms a discontinuous contact surface when in contact with the ice layer, reducing the adhesion area between the ice and the roller surface, helping to reduce the risk of ice block adhesion and avoiding the impact of ice accumulation on the normal operation of the equipment.

[0042] It should be noted that this utility model does not limit the winding type of the ribs 500 on the de-icing roller 310 and the pressure roller assembly 200. The ribs 500 can be in different forms such as ring, spiral, and diagonal, and their shape, height, spacing, and other parameters can be optimized according to the actual application scenario. For example, in cases of severe low-temperature icing and thick ice layers, taller ribs 500 with moderate spacing can be used to enhance the ice-breaking shearing force; while in cases of thinner ice layers or higher requirements for belt protection, a low and densely distributed rib structure can be selected to balance the de-icing effect with belt wear control.

[0043] In one embodiment of the present invention, the outer surface of the pressure roller assembly 200 is surrounded by a first rib segment 510 and a second rib segment 520, the first rib segment 510 and the second rib segment 520 having different surrounding directions; the outer surface of the de-icing roller 310 is surrounded by a third rib segment 530 and a fourth rib segment 540, the third rib segment 530 and the fourth rib segment 540 having different surrounding directions.

[0044] like Figures 1 to 2As shown, this technical solution further optimizes the contact characteristics with the conveyor belt 100 by setting a multi-directionally arranged rib structure 500 on the roller surface, enhancing ice-breaking, anti-slip, and self-cleaning capabilities. Specifically, the first rib segment 510 and the second rib segment 520 are spirally wound on the outer peripheral surface of the pressure roller assembly 200 in different directions, and the third rib segment 530 and the fourth rib segment 540 are also spirally distributed on the surface of the de-icing roller 310 in different directions. This layout not only increases the friction between the roller surface and the belt, but also creates a dynamic shearing action during operation, making it easier for the ice layer on the conveyor belt 100 to break and peel off, effectively improving ice-breaking efficiency and preventing ice layer from accumulating on the roller surface or belt.

[0045] In one embodiment of the present invention, the outer surface of the de-icing roller 310 is provided with raised ribs 500, and at least one of the de-icing rollers 310 has a different circumferential direction of ribs 500 than the circumferential direction of ribs 500 of the other de-icing rollers 310.

[0046] like Figures 1 to 5 As shown, by differentiating the spiral direction of the ribs 500 on the surface of each de-icing roller 310, a dynamic and staggered force distribution is formed during the revolution of multiple de-icing rollers 310, thereby further optimizing the removal effect of ice layer on the surface of the conveyor belt 100. Specifically, multiple de-icing rollers 310 are arranged along the polygonal mounting plate 320 and are all connected to the drive unit 400 to achieve revolution around a common rotation axis. Among them, the ribs 500 of at least one de-icing roller 310 are arranged in a left-handed or right-handed spiral, while the remaining de-icing rollers 310 adopt a spiral structure or straight stripe form in the opposite direction. This differentiated rib 500 layout can generate shearing force and friction force in different directions when the de-icing rollers 310 revolve with the mounting plate 320 and come into contact with the conveyor belt 100, enhancing the ice layer breaking effect and improving the discharge efficiency of ice and snow debris.

[0047] In one embodiment of the present invention, the drive unit 400 includes a coupling 410 and a geared motor 420. One end of the coupling 410 is fixedly connected to the geared motor 420, and the other end is fixedly connected to the drive shaft of the mounting plate 320.

[0048] like Figure 1 , Figure 2As shown, to achieve synchronous drive of the entire de-icing module, the technical solution of this utility model uses a geared motor 420 to provide stable power output, and a coupling 410 to efficiently transmit the power to the mounting plate 320 and the de-icing roller 310 assembly on it. Specifically, the geared motor 420, as the drive core, has the characteristics of large output torque, controllable speed, and smooth operation, and is suitable for de-icing operation scenarios that require precise control of rotation angle and speed. The coupling 410 is used to connect the output shaft of the geared motor 420 and the drive shaft of the mounting plate 320, ensuring coaxiality and stability during power transmission and avoiding vibration and wear caused by eccentricity or looseness. The drive shaft passes through the center of the mounting plate 320 or is located on one side of it, driving the entire mounting plate 320 and the multiple de-icing rollers 310 fixed on it to revolve around a common axis of rotation.

[0049] Furthermore, the drive unit 400 can also integrate a frequency converter or a servo control system to achieve precise adjustment of the speed and direction of the geared motor 420, so as to meet the de-icing requirements under different conveying speeds, ice thicknesses and ambient temperatures.

[0050] In one embodiment of the present invention, the pressure roller assembly 200 includes a first pressure roller 210 and a second pressure roller 220. The first pressure roller 210 forms a first contact point with the conveyor belt 100, and the second pressure roller 220 forms a second contact point with the conveyor belt 100. The contact point between the de-icing assembly 300 and the conveyor belt 100 is located between the first contact point and the second contact point.

[0051] like Figure 2 , Figure 3 As shown, the first pressure roller 210 and the second pressure roller 220 are respectively positioned above the conveyor belt 100 and distributed back and forth along the belt's running direction to ensure that the belt maintains good tension and fit during operation. The de-icing assembly 300 is located below the conveyor belt 100 and forms one or more contact points on its outer surface. These contact points are precisely between the contact points of the two pressure rollers, thus ensuring that the de-icing operation occurs in the belt area that is tensioned and stabilized by the pressure rollers, effectively improving de-icing efficiency and stability. This layout, through the rational arrangement of the relative positions of the pressure rollers and the de-icing assembly 300, achieves a synergistic effect of effective tensioning, stable support, and efficient de-icing of the conveyor belt 100.

[0052] In one embodiment of the present invention, the de-icing device for the belt conveyor further includes a collection bin 600, the lower part of which adopts a square funnel-shaped structure.

[0053] like Figure 3As shown, a collection chamber 600 is provided below the de-icing assembly 300. The collection chamber 600 corresponds to the working area of ​​the de-icing roller 310 to ensure that the stripped ice and snow flakes can fall directly into the chamber, thereby achieving effective collection and centralized treatment of the removed ice and snow debris. The lower part adopts a square funnel-shaped structure, which is conducive to the smooth discharge of ice and snow debris and avoids the accumulation of ice and snow from affecting the operation of the equipment or causing on-site environmental safety hazards.

[0054] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
