Description

Technical Field

[0001] This utility model relates to an improvement in the structure of belt idlers for belt conveyors, and more specifically to a belt idler bearing device. Background Technology

[0002] The microwave dryer for removing copper anode mud has multiple rotating shafts on its conveyor belt. The shafts typically have stainless steel protective layers on both sides, with a plastic microwave-insulating layer on the outside. The rotating bearings at the shaft ends are located within a closed area inside the protective layer (difficult to lubricate), and are connected to the oven shell by bolts at both ends. During use, under the weight of the material, the bolt holes in the shell are prone to deformation, making it difficult for the rubber-coated rollers to maintain a level surface for extended periods. Uneven friction between the microwave-insulating layer on the outside of the rollers and the conveyor belt easily causes localized wear and increases resistance. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned technical problems by providing a belt idler roller bearing device. By improving the bearing by placing it externally, it is easier to maintain and ensures that the idler roller moves synchronously with the belt.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a belt roller bearing device, comprising a microwave dryer frame, a bearing seat fixedly installed on the outer side of the microwave dryer frame, a positioning shaft installed on the inner side of the bearing in the bearing seat, a roller shaft fixedly connected to one end of the positioning shaft, a bushing movably fitted on the outer side of the connection between the roller shaft and the positioning shaft, and a bearing installed between the bushing and the positioning shaft.

[0005] Preferably, the bottom of the bearing housing is fixedly connected to the microwave dryer frame by bolts.

[0006] The beneficial effects of this invention are as follows: Before the improvement, the rotating bearings of the conveyor belt idlers in the copper-removing anode mud removal process suffered from slippage due to heat conduction. This caused the bearings to become sluggish, and the rolling friction between the idlers and the belt transformed into sliding friction, leading to belt slippage and accelerated conveyor belt wear. This invention, through localized improvements to the conveyor belt idlers and changes to the connection method between the idlers and the frame, minimizes the flatness deviation of all idler surfaces, ensuring uniform friction between the conveyor belt and idlers. It also facilitates regular lubrication of the idler rotating bearings, thus improving the service life of the conveyor belt. Attached Figure Description

[0010] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0011] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0012] Please see Figure 1 In the original microwave dryer for removing copper anode mud, the conveyor belt rollers had a support base 6 fixedly installed on the outside of the microwave desiccant frame 11. A rotating shaft 7 was fixedly connected to the side of the support base 6 via fixing bolts 8. A roller shaft cylinder 9 was movably sleeved on the outside of the rotating shaft 7, and a bearing 10 was installed between the roller shaft cylinder 9 and the rotating shaft 7. In this technical solution, the bearing 10 was located within a closed area inside the protective layer roller shaft cylinder 9, making manual lubrication impossible. The rotating shaft 7 was connected to the oven shell at both ends via fixing bolts 8 and the support base 6. Under the weight of the material, the bolt holes in the shell were prone to deformation, making it difficult for the rubber-coated rollers to maintain the same horizontal plane for extended periods. The uneven friction between the microwave isolation layer surface outside the rollers and the conveyor belt easily caused localized wear of the conveyor belt, increasing resistance.

[0013] Please see Figure 2 The present invention provides the following technical solution: an improved belt roller bearing device, including a microwave dryer frame 11, a bearing seat 1 fixedly installed on the outer side of the microwave dryer frame 11, a positioning shaft 2 installed on the inner side of the bearing of the bearing seat 1, a roller shaft 3 fixedly connected to one end of the positioning shaft 2, a bushing 4 movably fitted on the outer side of the connection between the roller shaft 3 and the positioning shaft 2, a bearing 5 installed between the bushing 4 and the positioning shaft 2, and the bottom of the bearing seat 1 fixedly connected to the microwave dryer frame 11 by bolts.

[0014] The working principle and usage process of this utility model are as follows: By setting the shaft end sleeve (i.e., roller shaft 9) and positioning shaft 2 of the material conveyor belt of the microwave dryer, the positioning shaft 2 is connected to the bearing seat (i.e., bearing 5), and the bearing seat 1 is fixed to the microwave dryer frame 11 by bolts, thereby changing the connection method between the roller and the frame, minimizing the flatness deviation of the upper surface of all rollers, keeping the friction between the conveyor belt and the rollers uniform, and by placing the bearing externally, it is easy to maintain and can be lubricated regularly, ensuring that the rollers and belt move synchronously and improving the service life of the conveyor belt.

[0015] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
