Description

Technical Field

[0001] The utility model relates to the technical field of heat insulation devices, in particular to a high-temperature protection device for a rotary kiln motor. Background Art

[0002] Rotary kilns are widely used in many production industries, including building materials, metallurgy, chemicals, and environmental protection. Rotary kilns are widely used to mechanically, physically, or chemically process solid materials. This type of equipment is called a rotary kiln. A rotary kiln is a rotating calcining kiln (commonly known as a rotary kiln) and belongs to the category of building materials equipment.

[0003] Rotary kilns typically operate at high temperatures. Despite certain insulation measures, the high temperature of the kiln body inevitably affects surrounding equipment. The motor driving the kiln is driven by rollers, meaning the motor is relatively close to the kiln. This makes the motor susceptible to the kiln's high temperature, causing it to overheat and affecting its efficiency. Therefore, a device is needed to effectively protect the motor from high temperatures. Utility Model Content

[0004] The purpose of the utility model is to provide a high-temperature protection device for a rotary kiln motor, which not only can play a role in heat insulation for the motor, but also can be conveniently moved to carry out maintenance on the motor.

[0005] The utility model is implemented through the following technical solutions: the high-temperature protection device for a rotary kiln motor of the utility model includes a motor, a base plate for supporting the motor, a slide rail arranged on the base plate, a slider sliding in the slide rail, and a protection plate arranged on the slider; the protection plate is arranged between the motor and the rotary kiln, and the length direction of the slide rail is perpendicular to the axial direction of the motor.

[0006] Furthermore, the slide rail includes a fixing bar, a first sliding groove of the fixing bar is opened along the length direction of the fixing bar, and the first sliding groove is an inverted T-shape; a horizontally arranged slide is provided at the lower end of the slider; the slider and the slide are both slidably arranged in the first sliding groove.

[0007] Furthermore, a connecting pipe is provided on the slide plate, and a fastening bolt is threadedly connected to the connecting pipe. A pressure plate is provided above the first slide groove, and the fastening bolt passes through the pressure plate and is threadedly connected to the connecting pipe.

[0008] Furthermore, a second inverted T-shaped sliding groove is provided on the side of the fixing bar, and the second sliding groove is connected to the first sliding groove; the second sliding groove is used for the sliding block and the sliding plate to pass through.

[0011] The technical solution of the present invention has at least the following advantages and beneficial effects: During installation, the slide rail is first installed on the base plate, and then the slider is clamped into the slide rail. A protective plate is placed between the motor and the rotary kiln. The protective plate blocks the high temperature of the rotary kiln from affecting the motor, significantly reducing the operating temperature of the motor and improving the stability of the motor.

DETAILED DESCRIPTION

[0020] Example

[0021] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 6 As shown, the rotary kiln motor high-temperature protection device of this embodiment includes a motor 12, a base plate 11 for supporting the motor 12, a slide rail 20 provided on the base plate 11, a slider 31 slidably provided in the slide rail 20, and a protective plate 36 provided on the slider 31. The protective plate 36 is provided between the motor 12 and the rotary kiln 13, and the length direction of the slide rail 20 is perpendicular to the axial direction of the motor 12. Specifically, during installation, the slide rail 20 is first installed on the base plate 11, and then the slider 31 is inserted into the slide rail 20. The protective plate 36 is provided between the motor 12 and the rotary kiln 13. The protective plate 36 blocks the influence of the high temperature of the rotary kiln 13 on the motor 12, significantly reducing the operating temperature of the motor 12 and improving the operating stability of the motor 12. When the motor 12 needs to be inspected or maintained, the protective plate 36 and the slider 31 can be moved to the side close to the rotary kiln 13 before the motor 12 is operated. In this way, the presence of the protective plate 36 will not affect the operator's operation of the motor 12, and there is no need to completely remove the protective plate 36, which makes the operation more convenient and efficient.

[0022] The slide rail 20 in this embodiment includes a fixed bar 21, a first slide groove 22 extending along the length of the fixed bar 21, and an inverted T-shaped first slide groove 22. A horizontally disposed slide plate 32 is disposed at the lower end of a slider 31. Both the slider 31 and the slide plate 32 slide in the first slide groove 22. Specifically, the slider 31 and the slide plate 32 are stably secured in the first slide groove 22, preventing the protective plate 36 from tilting or shaking.

[0023] In this embodiment, the slide plate 32 is provided with a connecting tube 33, which is threadedly connected to a fastening bolt 34. A pressure plate 35 is provided above the first chute 22, and the fastening bolt 34 passes through the pressure plate 35 and is threadedly connected to the connecting tube 33. Specifically, by tightening the fastening bolt 34, the slide plate 32 and the slider 31 can be completely fixed by the pressure plate 35 and the connecting tube 33, preventing them from shaking or displacement during use.

[0024] In this embodiment, the fixing bar 21 is provided with an inverted T-shaped second slot 23 on its side. The second slot 23 is connected to the first slot 22 and is used to pass through the slider 31 and the plate 32. Specifically, during installation, the slider 31 and the plate 32 are inserted into the first slot 22 through the second slot 23. After adjusting their positions, tighten the fastening bolts 34. During disassembly, they can be directly removed from the second slot 23, making both installation and disassembly very convenient.

[0025] The protective plate 36 in this embodiment includes a support plate 361 connected to the slider 31, and an arc-shaped heat insulation plate 362 provided on the support plate 361; the support plate 361 is vertically arranged. The heat insulation plate 362 is a hollow structure, and a heat insulation layer 363 is provided inside the heat insulation plate 362. Specifically, during use, the heat insulation plate 362 not only has to withstand the high temperature of the rotary kiln 13, but also has to withstand the high-frequency vibration generated by the motor 12. Therefore, the durability of the heat insulation layer 363 is not high and it is easily damaged. After damage, it can be directly removed and replaced with a new heat insulation plate 362. There is no need to replace the entire protective plate 36. In addition, the heat insulation plate 362 itself is made of stainless steel, and the heat insulation layer 363 is made of materials such as heat insulation cotton. While ensuring the mechanical strength of the protective plate 36, it also has a better heat insulation effect.

[0026] In summary, during installation, the rotary kiln motor high-temperature protection device of this embodiment first installs the slide rail 20 on the base plate 11, then inserts the slider 31 into the slide rail 20, and places the protective plate 36 between the motor 12 and the rotary kiln 13. The protective plate 36 blocks the high temperature of the rotary kiln 13 from affecting the motor 12, significantly reducing the operating temperature of the motor 12 and improving the operational stability of the motor 12. When the motor 12 needs to be inspected or maintained, the protective plate 36 and slider 31 can be moved closer to the rotary kiln 13 before operating the motor 12. In this way, the presence of the protective plate 36 will not affect the operator's operation of the motor 12, and there is no need to completely remove the protective plate 36, making operation more convenient and efficient.

[0027] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
