Description

Technical Field

[0001] This utility model belongs to the field of rotary kilns, and specifically relates to a graphite lubrication device that can automatically adjust its position according to the heating changes of the rotary kiln. Background Technology

[0002] A rotary kiln is a piece of equipment used for firing materials, widely used in industries such as cement, metallurgy, chemicals, and building materials. Its main function is to process raw materials at high temperatures into finished products. The working principle of a rotary kiln is based on heat conduction and the movement of matter, employing either intermittent or continuous production. Due to its simple structure, ease of operation, and high processing capacity, the rotary kiln has become an indispensable piece of equipment in many industrial processes.

[0003] During the production process of a rotary kiln, considerable friction occurs between the rotary kiln tire and the support rollers. If proper lubrication is not performed, this friction can lead to problems such as accelerated tire wear and tire runout, thereby shortening the service life of the rotary kiln.

[0004] Currently, the method involves manually applying grease to the front and rear support rollers of each rotary kiln once per shift. This long lubrication interval negatively impacts the service life of the tires. However, controlling the amount of grease applied manually is difficult; insufficient application causes wear, while excessive application wastes grease. There is no standardized reference, making it uncontrollable. Existing patents only support graphite lubrication and cannot automatically adjust the lubrication device's position according to the thermal expansion and contraction of the rotary kiln. Utility Model Content

[0005] Purpose of the utility model: The present utility model aims to provide a graphite lubrication device that can automatically adjust its position according to the heating changes of the rotary kiln, ensuring that the graphite lubrication position always matches the friction contact area, improving the lubrication effect between the support roller and the tire, reducing maintenance costs, and extending the service life of the equipment.

[0006] Technical Solution: The graphite lubrication device of this utility model, which can automatically adjust its position according to the heating changes of the rotary kiln, includes a rotary kiln tire, a rotary kiln support roller, support roller bearings on both sides of the rotary kiln support roller, and a graphite lubrication device mounted on the support roller bearings. The graphite lubrication device includes a guide roller mechanism, a graphite box, a mounting assembly, and a guide roller assembly. The graphite box moves synchronously with the shaft on the rotary kiln tire through the guide roller mechanism. The graphite box is mounted on the guide roller assembly through the mounting assembly, and the graphite box and the mounting assembly are connected by a hole-shaft structure. The guide roller assembly is fixed on the support roller bearing.

[0007] Furthermore, the guide wheel mechanism includes a guide wheel, a guide wheel seat, a retaining ring, a guide wheel shaft, and a guide wheel plate. The guide wheel is mounted on the guide wheel seat via the guide wheel shaft. A retaining ring is provided on the outer side of the guide wheel shaft. The guide wheel seat is fixed to the top of the guide wheel plate, and the bottom of the guide wheel plate is mounted on the graphite box.

[0008] Furthermore, the guide wheel mechanism is distributed on both sides of the rotary kiln belt, the radial direction of the guide wheel in the guide wheel mechanism is perpendicular to the radial direction of the rotary kiln belt, and the rotation direction of the guide wheel is consistent with the tangential direction of the rotary kiln belt.

[0009] Furthermore, the graphite box is equipped with a counterweight ball and a graphite block inside. The counterweight ball is used to press the graphite block so that the graphite block extends out of the graphite box and comes into close contact with the rotary kiln support roller.

[0010] Furthermore, the mounting assembly includes a mounting bracket and a mounting base. The mounting bracket includes an upper bracket and a lower bracket. The upper bracket is an inclined bracket used to support the graphite box and adjust the contact area between the graphite block in the graphite box and the rotary kiln support roller. The lower bracket is a mounting panel used to be fixedly connected to the mounting base.

[0011] Furthermore, the mounting base is provided with several height adjustment holes, and the mounting panel is provided with connection holes that mate with the height adjustment holes.

[0012] Furthermore, the guide wheel assembly includes two sets of guide wheels and a guide wheel base plate, the two sets of guide wheels being symmetrically distributed on the guide wheel base plate; the guide wheel includes a slider and a sliding rod, the slider being used for fixing the mounting assembly, and the sliding rod being used for moving the slider.

[0013] Furthermore, the graphite box and the guide wheel mechanism are connected by a hole-shaft structure.

[0014] Furthermore, the connection between the guide wheel mechanism and the mounting assembly and the graphite box is a two-hole shaft structure, which can be adjusted separately.

[0015] Beneficial effects: Compared with the prior art, the present invention has the following advantages: (1) The tire and the lubrication device move synchronously in the axial direction through the linkage mechanism-guide wheel mechanism; (2) The graphite box can rotate around the shaft through the rotatable structure-hole shaft structure, and the contact area between the graphite and the support roller can be adjusted arbitrarily; (3) The lubrication device can slide in the axial direction with the tire when the rotary kiln is heated and elongated in the axial direction through the sliding mechanism-guide wheel assembly, ensuring that the lubrication surface is always the contact surface; (4) The graphite block is installed on the rotary kiln support roller, and the friction between the tire and the support roller is reduced through the lubrication effect of the graphite, thereby improving the production efficiency of the rotary kiln and reducing energy consumption.

[0029] The present invention will now be further described in conjunction with specific embodiments and accompanying drawings.

[0030] Example 1: As Figure 1 As shown, the graphite lubrication device of this utility model that can automatically adjust its position according to the heating changes of the rotary kiln includes a rotary kiln belt 1, a rotary kiln support roller 2, support roller bearings 4 located on both sides of the rotary kiln support roller 2, and a graphite lubrication device 3 installed on the support roller bearings 4.

[0031] like Figure 2As shown, the graphite lubrication device 3 includes a guide wheel mechanism 31, a graphite box 32, a mounting assembly, and a guide wheel assembly. The graphite box 32 moves synchronously with the shaft on the rotary kiln belt 1 via the guide wheel mechanism 31. The graphite box 32 is mounted on the guide wheel assembly via the mounting assembly. The connection between the guide wheel mechanism 31, the mounting assembly, and the graphite box 32 is a two-hole shaft structure, which can be adjusted separately. The guide wheel assembly is fixed on the support roller bearing 4.

[0032] The graphite box 32 is equipped with a counterweight ball 37 and a graphite block 38 inside. The counterweight ball 37 is used to press the graphite block 38 so that the graphite block extends out of the graphite box 38 and comes into close contact with the rotary kiln support roller 2.

[0033] like Figure 3 As shown, the guide wheel mechanism 31 includes a guide wheel 311, a guide wheel seat 312, a retaining ring 313, a guide wheel shaft 314, and a guide wheel plate 315. The guide wheel 311 is mounted on the guide wheel seat 312 via the guide wheel shaft 314. A retaining ring 313 is provided on the outer side of the guide wheel shaft 314. The guide wheel seat 312 is fixed to the top of the guide wheel plate 315, and the bottom of the guide wheel plate 315 is mounted on the graphite box 32. The guide wheel mechanism 31 is distributed on both sides of the rotary kiln belt 1. The direction of movement of the guide wheel 311 in the guide wheel mechanism 31 is perpendicular to the direction of movement of the rotary kiln belt 1. The radial direction of the guide wheel 311 in the guide wheel mechanism 31 is perpendicular to the radial direction of the rotary kiln belt 1, and the rotation direction of the guide wheel 311 is consistent with the tangential direction of the rotary kiln belt 1.

[0034] The mounting assembly includes a mounting bracket 33 and a mounting base 34. The mounting bracket includes an upper bracket and a lower bracket. The upper bracket is an inclined bracket used to support the graphite box 32 and adjust the contact area between the graphite block 38 in the graphite box 32 and the rotary kiln support roller 2. The lower bracket is a mounting panel used to fix it to the mounting base 34. The mounting base 34 is provided with several height adjustment holes, and the mounting panel is provided with connection holes that mate with the height adjustment holes.

[0035] The guide wheel assembly includes two sets of guide wheels 35 and a guide wheel base plate 36. The two sets of guide wheels 35 are symmetrically distributed on the guide wheel base plate 36. The guide wheel includes a slider and a slide rod. The slider is used to fix the mounting base 34, and the slide rod is used to move the slider.

[0036] The structural diagrams of the parts of the guide wheel mechanism, graphite box, mounting components, and guide wheel assembly are shown below. Figures 4-13 As shown.

[0037] The working principle of the above device is as follows:

[0038] The graphite block 38 is placed in the graphite box 32, and a counterweight ball 37 is placed on top of the graphite block 38 to ensure that the graphite block 38 is always in close contact with the rotary kiln support roller 2.

[0039] Using the fixing holes of the roller bearing 4, the mounting base plate 34 is fixed to the roller bearing 4 through the guide rail assembly, and the mounting bracket 33 is fixed to the mounting base plate 34; the graphite box 32 is mounted on the mounting bracket 33, and the graphite box 32 and the mounting bracket 33 adopt a hole-shaft structure, so that the graphite box 32 can rotate around the shaft and the contact area between the graphite block 38 and the rotary kiln roller 2 can be adjusted arbitrarily.

[0040] One end of the guide wheel plate 315 in the guide wheel assembly 31 is mounted on the mounting bracket 33, and the other end is equipped with a guide wheel 311. The guide wheel 311 is in close contact with the rotary kiln belt 1. The rotation direction of the guide wheel 311 is consistent with the tangential direction of the belt 1. The guide wheel assembly 31 drives the guide rail assembly 34 to slide on the guide rail 35, which can realize the synchronous movement of the rotary kiln belt 1 and the graphite lubrication device 3 in the axial direction.
