Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical engineering lubrication technology, and in particular to an automatic adjustment lubrication device for graphite blocks. Background Technology
[0002] Automatic graphite block lubrication devices, as a crucial component of rotary equipment lubrication systems, are primarily used to address malfunctions in large equipment caused by improper lubrication. They achieve automatic lubrication by using spring preload to drive graphite blocks, and utilize adjusting screws, guide shafts, and other components to ensure precise and stable lubrication. They hold key application value in rotary kiln equipment in metallurgy, building materials, and other fields. In practical applications, this type of lubrication device typically includes the following core structure:
[0003] 1. Housing assembly: Serves as the mounting base for the device, used to fix components such as the adjusting spring device and guide bushing, and also contains graphite blocks to provide lubrication medium.
[0004] 2. Elastic adjustment mechanism: It consists of spring, adjusting screw, adjusting nut, etc. The graphite block is automatically pushed by adjusting the spring preload to ensure continuous lubrication.
[0005] 3. Guiding and positioning components: including guide shaft, guide shaft sleeve and spring sleeve, used to ensure uniform distribution of spring force, prevent spring torsion, and ensure the accuracy of the push plate movement trajectory.
[0006] 4. Actuating component: The push plate pushes the graphite block toward the working surface under the action of spring force, so as to achieve direct lubrication of the friction parts of the equipment.
[0007] Currently, the industry primarily employs the following methods for lubricating rotary equipment: some equipment uses time-controlled oil lubrication systems, which reduce wear by forming an oil film on the friction surfaces; others rely on manual, periodic application of solid lubricant, with operators manually replenishing the lubricating medium; a few high-end machines are equipped with automatic grease injection systems, which use pressure pumps to spray grease to the lubrication points. To optimize lubrication, some manufacturers have adopted improved oil lubrication devices, adding impurity filtration structures. Others have developed intelligent grease distribution systems that monitor lubrication status using sensors and automatically adjust the oil supply. Still others are experimenting with composite lubricating materials, mixing solid lubricants with grease to enhance lubrication performance.
[0008] However, the above-mentioned implementation methods still have the following problems: In terms of lubrication safety, oil lubrication systems pose a risk of fire caused by molten copper splashing under high-temperature conditions such as metallurgy, threatening the safe operation of equipment. In terms of lubrication reliability, manual lubrication methods suffer from problems such as untimely replenishment and uneven dosage, which can easily lead to increased equipment wear. Traditional automatic lubrication devices are difficult to dynamically adjust the amount of lubrication according to the wear of the equipment, resulting in unstable lubrication effects. In terms of application adaptability, most lubrication devices cannot work normally in extreme high-temperature, low-temperature, or humid environments, limiting their applicability. In terms of economic cost, oil lubrication systems require regular replacement of lubricating oil and filter elements, resulting in high maintenance costs. When equipment fails due to improper lubrication, it can cause huge repair and manpower losses. To address this problem, this application proposes a solution: designing a safe, reliable, automatically adjustable graphite block lubrication device that is adaptable to various working conditions. This device replaces traditional lubricating oil with graphite blocks, eliminating the risk of fire. It uses an elastic automatic adjustment mechanism to achieve dynamic compensation of the amount of lubrication, enabling stable operation in harsh environments and effectively reducing equipment maintenance costs and failure losses.
