Description

Technical Field

[0001] This utility model relates to the field of grinding and polishing technology for rotary kiln liner production, specifically to a grinding and polishing device for rotary kiln liner production. Background Technology

[0002] The inner liner of a rotary kiln typically refers to the refractory material structure inside the rotary kiln. It is an important component that protects the kiln shell from damage caused by high-temperature gases and materials. The material and structure of the inner liner directly affect the service life, energy efficiency, and production stability of the rotary kiln. The grinding and polishing device for rotary kiln inner liner production is a type of mechanical equipment specifically designed for precision grinding and polishing of the inner wall of the rotary kiln during the production process. This device is designed to ensure that the surface roughness of the rotary kiln inner liner meets specific industrial standards in order to optimize the heat exchange efficiency of materials, reduce wear, and extend equipment life.

[0003] In the existing rotary kiln inner liner production process, the polishing device can only polish the inner part of the inner liner locally, resulting in poor polishing uniformity.

[0004] Therefore, we propose a grinding and polishing device for rotary kiln liner production that can polish the interior of the rotary kiln liner from all directions to improve the polishing uniformity. Utility Model Content

[0005] The purpose of this invention is to provide a grinding and polishing device for the production of rotary kiln inner liner, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grinding and polishing device for producing rotary kiln liner, comprising a placement plate, a support plate hinged to the bottom of the placement plate, a base fixedly installed at the bottom of the support plate, an electric push rod hinged to the top surface of the base, a rotary kiln liner body disposed above the placement plate, and a processing assembly disposed above the placement plate, the processing assembly including a polishing assembly disposed above the placement plate, and an adjustment assembly disposed inside the polishing assembly.

[0007] Preferably, the polishing assembly includes a vertical plate fixedly installed on the top surface of the placement plate, an mounting plate fixedly installed on the outer wall of the vertical plate, a motor fixedly installed on the outer wall of the mounting plate, a rotating rod fixedly installed at the output end of the motor, a polishing plate disposed on the outer side of the rotating rod, a polishing brush fixedly installed on the outer wall of the polishing plate, a transmission mechanism fixedly sleeved on the outer wall of the rotating rod, a support ring fixedly installed on the top surface of the placement plate, a limit ring rotatably connected inside the support ring, a gear ring sleeved on the outer wall of the limit ring, a gear meshing with a gear, a rotating shaft sleeved inside the gear, and a cylinder fixedly installed on the inner wall of the limit ring.

[0008] Preferably, the adjusting assembly includes a sleeve fixedly installed on the outer wall of the rotating rod, a spring fixedly installed inside the sleeve, a limit plate fixedly installed at the end of the spring, and a slide rod fixedly installed on the side of the limit plate away from the spring.

[0009] Preferably, the outer wall of the rotating shaft is fixedly sleeved inside the transmission mechanism, and the rotating rod is rotatably connected to the rotating shaft through the transmission mechanism. Under the restriction of the transmission mechanism, the rotating rod can drive the rotating shaft to rotate.

[0010] Preferably, the outer wall of the rotating shaft is rotatably connected to the inside of the vertical plate, and the gear ring is rotatably connected to the support ring through a limiting ring. Under the support of the support ring, the rotating shaft drives the gear to rotate stably, and the gear ring meshing with the gear drives the limiting ring to rotate inside the support ring.

[0011] Preferably, one end of the spring is fixedly installed on the side of the limiting plate away from the slide rod, and the other end of the spring away from the limiting plate is fixedly installed inside the sleeve near the rotating rod. Under the elastic action of the spring, the polishing plate can be pushed by the limiting plate and the slide rod, so that the polishing plate and the polishing brush come into contact with the inner wall of the rotary kiln liner, without the need for the operator to change polishing plates of different sizes.

[0012] Preferably, the end of the slide rod away from the limiting plate is fixedly installed on the side of the polishing plate away from the polishing brush. The outer wall of the slide rod is slidably disposed inside the sleeve. Under the restriction of the slide rod, the polishing plate is pushed by the spring, so that the polishing plate is in close contact with the polishing brush and the inner wall of the rotary kiln liner body, so as to polish the rotary kiln liner body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This grinding and polishing device for rotary kiln liner production comprises a polishing assembly. When polishing the rotary kiln liner body is required, the liner body is placed inside the limiting ring, and the cylinder is activated to clamp the liner body. At this time, the motor is started, and the rotating rod fixed at its output end rotates accordingly. The rotating rod, through a sleeve and a sliding rod, drives the polishing plate to rotate. The polishing plate and polishing brush polish the interior of the rotary kiln liner body. Grinding balls are added to the interior of the liner body. The rotating rod, through a transmission mechanism, drives the rotating shaft to rotate accordingly. The gear sleeved on the outer wall of the rotating shaft rotates accordingly. Because the limiting ring sleeved inside the gear ring is rotatably connected to the support ring, under its constraint, the rotating gear can drive the gear ring to rotate stably, causing the gear ring to drive the limiting ring to rotate. The rotation of the limiting ring causes the rotary kiln inner body, which is held inside the limiting ring, to rotate accordingly. The grinding balls inside the rotary kiln inner body come into contact with the inner wall of the rotary kiln inner body for grinding. This structure can polish the inside of the rotary kiln inner body by rotating the polishing brush and polishing plate. When the limiting ring drives the rotary kiln inner body to rotate, the rotary kiln inner body comes into contact with the grinding balls inside it for grinding. The rotation direction of the rotary kiln inner body is opposite to the rotation direction of the polishing brush. Under this restriction, the grinding effect can be improved, so that the inside of the rotary kiln inner body can be ground evenly. After grinding is completed, the electric push rod is activated to push the placement plate, so that the hinge point between the placement plate and the support plate is the rotation center, and the grinding balls inside the rotary kiln inner body are unloaded.

[0015] 2. The grinding and polishing device for rotary kiln liner production consists of an adjustment component. When polishing rotary kiln liner bodies of different sizes is required, when the rotary kiln liner body is sleeved outside the rotating rod, the limiting plate is pushed under the elastic action of the spring, causing the limiting plate to drive the sliding rod to slide outward of the sleeve. This allows the polishing plate, which is fixedly installed at the end of the sliding rod, to contact the polishing brush and the inner wall of the rotary kiln liner body. Under the elastic action of the spring, the position of the polishing plate can be flexibly adjusted according to the size of the rotary kiln liner body, so as to polish the interior of the rotary kiln liner body of different sizes.

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] Example 1: A preferred embodiment of the grinding and polishing device for rotary kiln liner production provided by this utility model is as follows: Figures 1 to 6 As shown: A grinding and polishing device for producing rotary kiln liner, including a placement plate 1;

[0025] The bottom of the placement plate 1 is hinged to a support plate 2;

[0026] The base 3 is fixedly installed at the bottom of the support plate 2;

[0027] An electric push rod 5 is hinged to the top surface of the base 3;

[0028] The rotary kiln inner body 6 is installed above the placement plate 1;

[0029] The processing assembly 4 is disposed above the placement plate 1. The processing assembly 4 includes a polishing assembly 41 disposed above the placement plate 1. The polishing assembly 41 includes a vertical plate 417 fixedly installed on the top surface of the placement plate 1. A mounting plate 411 is fixedly installed on the outer wall of the vertical plate 417. A motor 412 is fixedly installed on the outer wall of the mounting plate 411. A rotating rod 413 is fixedly installed at the output end of the motor 412. A polishing plate 414 is disposed on the outer side of the rotating rod 413. A polishing brush 415 is fixedly installed on the outer wall of the polishing plate 414. A transmission mechanism 416 is fixedly sleeved on the outer wall of the rotating rod 413. A support ring 418 is fixedly installed on the top surface of the placement plate 1. A limit ring 419 is rotatably connected inside the support ring 418. A gear ring 420 is sleeved on the outer wall of the limit ring 419. A gear 421 meshes with the gear ring 420. A rotating shaft 422 is sleeved inside the gear 421. A cylinder 423 is fixedly installed on the inner wall of the limit ring 419.

[0030] In this embodiment, when polishing of the rotary kiln inner liner body 6 is required, the rotary kiln inner liner body 6 is placed inside the limiting ring 419, and the cylinder 423 is started, which clamps the rotary kiln inner liner body 6. At this time, the motor 412 is started, and the rotating rod 413 fixed at its output end rotates accordingly. The rotating rod 413 drives the polishing plate 414 to rotate through the sleeve 431 and the slide rod 434. The polishing plate 414 and the polishing brush 415 polish the inside of the rotary kiln inner liner body 6. Grinding balls are added to the inside of the rotary kiln inner liner body 6. The rotating rod 413 drives the rotating shaft 422 to rotate accordingly through the transmission mechanism 416. The gear 421 sleeved on the outer wall of the rotating shaft 422 rotates accordingly. Since the limiting ring 419 sleeved inside the gear ring 420 is rotatably connected to the support ring 418, under its restriction, the rotating gear 421 can drive the gear ring 420 to rotate stably, so that the gear ring 420 The limiting ring 419 rotates accordingly, causing the rotary kiln inner liner body 6 clamped inside the limiting ring 419 to rotate as well. The grinding balls inside the rotary kiln inner liner body 6 come into contact with the inner wall of the rotary kiln inner liner body 6 for grinding treatment. This structure can polish the inside of the rotary kiln inner liner body 6 by rotating the polishing brush 415 and the polishing plate 414. When the limiting ring 419 drives the rotary kiln inner liner body 6 to rotate, the rotary kiln inner liner body 6 comes into contact with the grinding balls inside it for grinding. Moreover, the rotation direction of the rotary kiln inner liner body 6 is opposite to the rotation direction of the polishing brush 415. Under its restriction, the grinding effect can be improved, so that the inside of the rotary kiln inner liner body 6 can be ground comprehensively, making the grinding and polishing more uniform. After the grinding is completed, the electric push rod 5 is activated to push the placement plate 1, so that the hinge point between the placement plate 1 and the support plate 2 is the rotation center, and the grinding balls inside the rotary kiln inner liner body 6 are unloaded.

[0031] Furthermore, the outer wall of the rotating shaft 422 is fixedly sleeved inside the transmission mechanism 416, and the rotating rod 413 is rotatably connected to the rotating shaft 422 through the transmission mechanism 416. Under the restriction of the transmission mechanism 416, the rotating rod 413 can drive the rotating shaft 422 to rotate.

[0032] Furthermore, the outer wall of the rotating shaft 422 is rotatably connected to the inside of the upright plate 417, and the gear ring 420 is rotatably connected to the support ring 418 through the limiting ring 419. Under the support of the support ring 418, the rotating shaft 422 drives the gear 421 to rotate stably, and the gear ring 420 meshing with the gear 421 drives the limiting ring 419 to rotate inside the support ring 418.

A slide rod 434 is fixedly installed on the side of the limit plate 433 away from the spring 432.

[0034] In this embodiment, when it is necessary to polish the rotary kiln inner body 6 of different sizes, when the rotary kiln inner body 6 is sleeved outside the rotating rod 413, the limiting plate 433 is pushed by the elastic action of the spring 432, so that the limiting plate 433 drives the sliding rod 434 to slide towards the outside of the sleeve 431, so that the polishing plate 414 fixedly installed at the end of the sliding rod 434 contacts the polishing brush 415 and the inner wall of the rotary kiln inner body 6. Under the elastic action of the spring 432, the polishing plate 414 can be flexibly adjusted according to the size of the rotary kiln inner body 6, so as to polish the inside of the rotary kiln inner body 6 of different sizes.

[0035] Furthermore, one end of the spring 432 is fixedly installed on the side of the limiting plate 433 away from the slide rod 434, and the other end of the spring 432 away from the limiting plate 433 is fixedly installed inside the sleeve 431 near the rotating rod 413.

[0036] In addition, the end of the slide rod 434 away from the limiting plate 433 is fixedly installed on the side of the polishing plate 414 away from the polishing brush 415. The outer wall of the slide rod 434 is slidably set inside the sleeve 431. Under the restriction of the slide rod 434, the polishing plate 414 is pushed by the spring 432, so that the polishing plate 414 is in close contact with the polishing brush 415 and the inner wall of the rotary kiln inner liner body 6, so as to perform polishing work on the rotary kiln inner liner body 6.
