Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of roller kiln, more particularly, to a roller kiln transmission cooling system and a roller kiln device. BACKGROUND

[0002] The roller kiln is widely used in the production of building, daily and sanitary ceramic products. The ceramic roller is a key component of the roller kiln, which plays a role in supporting and conveying ceramic products and completing the sintering process.

[0003] The traditional building ceramic roller kiln transmission system driving process is: transmission motor→gear reduction box→main shaft driving gear→main shaft→large gear→small gear→roller sleeve→roller→driven end support bearing. The firing temperature in the ceramic roller kiln is generally more than 1200℃. During the rotation of the roller, a certain gap is formed between the roller and the cotton at the hole brick, which leads to a higher temperature outside the hole brick. In order to avoid the deformation of the roller sleeve due to high temperature, the safe distance between the roller sleeve and the outermost side of the roller kiln frame is generally 100mm during installation of the roller kiln transmission system, and the safe distance between the driven end support and the outermost side of the roller kiln frame is generally 80mm, which further leads to large roller span, large bending deformation and large load deformation.

[0004] The curved ceramic roller will change the running route of the products in the kiln, and the products may be squeezed or collided with each other, which seriously affects the quality and yield of the fired products.

[0005] Therefore, the prior art needs to be improved. CONTENT OF THE UTILITY MODEL

[0063] Embodiment 1:

[0064] Please refer to Figure 1 The embodiment provides a roller kiln transmission cooling system, which comprises a kiln body 100, a transmission platform 200 composed of a plurality of ceramic roller bars 210, a hole brick 300 and a heat insulation sealing plate 400 Figure 4As shown in FIG. 1, the kiln body 100 includes left and right kiln walls 110, the transmission platform 200 is arranged on the left and right kiln walls 110, the hole brick 300 is arranged at a middle position of the kiln wall 110, the hole brick 300 is used for arranging the ceramic roller 210, so that the ceramic roller 210 is rotatably arranged on the kiln wall 110, the heat insulation sealing plate 400 is arranged outside the hole brick 300, and the ceramic roller 210 passes through the heat insulation sealing plate 400 and is rotatably arranged on the heat insulation sealing plate 400, and the heat insulation sealing plate 400 is used for forming a heat insulation layer outside the hole brick 300.

[0065] In the embodiment, the heat insulation sealing plate 400 is arranged outside the hole brick 300, the heat insulation sealing plate 400 can insulate the heat transfer of the hole brick 300 gap 310, so as to reduce the temperature outside the kiln at the hole brick 300, the driven end support distance and the active end support distance can be reduced, and the support span L of the ceramic roller 210 can be reduced. Figure 5 In the embodiment, the driven end support distance refers to the distance between the support distance of the driven end and the adjacent kiln wall 110, and the active end support distance refers to the distance between the support distance of the active end and the adjacent kiln wall 110. The heat insulation sealing plate 400 can block the gap 310 of the hole brick 300 while allowing the ceramic roller 210 to rotate freely, so as to reduce the high temperature of the outer wall caused by the overflow of the high temperature flue gas in the kiln from the gap between the hole brick 300 and the ceramic roller 210. That is, the temperature outside the kiln wall 110 at the hole brick 300 can be reduced, the safety distance of the ceramic roller 210 support can be reduced, and the support span L of the ceramic roller 210 can be reduced.

[0066] Therefore, the heat insulation sealing plate 400 is arranged outside the hole brick 300 to form a heat insulation layer outside the hole brick 300, so as to prevent the temperature outside the kiln at the hole brick 300 from being too high, the distance from the driven end support and the active end support to the kiln wall 110 can be reduced, the support span L of the ceramic roller 210 can be reduced, the high temperature deformation of the ceramic roller 210 can be improved, and the firing quality of the building ceramic product can be improved.

[0067] Specifically, referring to FIG. 4, Figure 4 The heat insulation sealing plate 400 includes a plurality of heat insulation unit plates, and the plurality of heat insulation unit plates are spliced to form the heat insulation sealing plate 400. The heat insulation unit plate includes a fiber unit plate 410 and a splicing groove 420 arranged on the side wall of the fiber unit plate 410, and the splicing groove 420 is used for splicing with another fiber unit plate 410.

[0068] In the embodiment, the several heat insulation unit plates are spliced to form the heat insulation sealing plate 400, which is equivalent to laying the spliced heat insulation unit plates outside the hole brick 300, and the structure is simple and easy to realize. The heat insulation unit plate comprises a fiber unit plate 410 and a splicing groove 420. The fiber unit plate 410, i.e. the heat insulation unit plate, is made of a fiber plate, for example, a zirconium-containing fiber plate, to achieve heat insulation. The fiber unit plate 410 can be provided with a via hole for mounting the ceramic roller bar 210, and the ceramic roller bar 210 can rotate in the via hole. The ceramic roller bar 210 can be tightly attached to the fiber unit plate 410, and the ceramic roller bar 210 and the hole brick 300 need to be kept a certain gap 310 to ensure free rotation. The fiber unit plate 410 can block the gap 310 between the ceramic roller bar 210 and the hole brick 300, effectively reducing the temperature outside the kiln wall 110 at the hole brick 300. The splicing groove 420 can be arranged on the left and right sides of the heat insulation unit plate, so that two heat insulation unit plates can be spliced with each other through the splicing groove 420, firmly connected and sealed and heat-insulated.

[0069] Specifically, the roller kiln transmission and cooling system further comprises a kiln frame 120, a driving end support assembly 130 and a driven end support assembly 140. The kiln frame 120 comprises a left side frame 121 and a right side frame 122. The driving end support assembly 130 is arranged on the inner side of the right side frame 122 and is used to support the driving end of the ceramic roller bar 210. The driven end support assembly 140 is arranged on the inner side of the left side frame 121 and is used to support the driven end of the ceramic roller bar 210. The driven end support assembly 140 cooperates with the driving end support assembly 130 to reduce the support span L of the ceramic roller bar 210.

[0070] In the prior art, please refer to Figure 2 and Figure 3, the hole brick 300 and the gap 310 of the ceramic roller 210 are filled with heat insulation cotton. Due to the rotation of the ceramic roller 210 and the high temperature environment, the gap of the heat insulation cotton at the gap 310 will gradually expand, resulting in heat escaping from the gap 310 of the rotating hole. Therefore, in order to avoid deformation of the roller support due to high temperature, the distance between the ceramic roller 210 and the outermost side of the roller kiln frame is generally 100mm during installation of the driving end support, and the distance between the ceramic roller 210 and the outermost side of the roller kiln frame is generally 80mm during installation of the driven end support. Therefore, the driving end support is installed on the outside of the right side frame 122, and the driven end support is installed on the outside of the left side frame 121, so that the ceramic roller 210 has a large span, a large bending deformation and a large load deformation. In the embodiment, the driving end support assembly 130 is arranged on the inside of the right side frame 122 of the kiln frame 120, and the driven end support assembly 140 is arranged on the inside of the left side frame 121 of the kiln frame 120, so that the support span L of the ceramic roller 210 is greatly reduced, thereby reducing the deformation of the ceramic roller 210.

[0071] Specifically, referring to Figure 6 The driving end support assembly 130 comprises a first support frame 131 and a plurality of first bearings 132. The first support frame 131 is arranged on the inside of the right side frame 122 and is located on the outside of the right side heat sealing plate 400. The plurality of first bearings 132 are arranged on the first support frame 131 and are used to support the driving end of the ceramic roller 210.

[0072] In the embodiment, the driving end support assembly 130 comprises a first support frame 131 and a plurality of first bearings 132. The first support frame 131 is arranged on the inside of the right side frame 122, i.e. the first support frame 131 is arranged on the side of the right side frame 122 close to the hole brick 300. The first bearings 132 are installed on the first support frame 131 and are used to support the driving end of the ceramic roller 210. Since the hole brick 300 is provided with the heat sealing plate 400 on the outside, the temperature at the gap 310 of the hole brick 300 can be reduced, so that the first support frame 131 can be installed on the inside of the right side frame 122 to reduce the span of the ceramic roller 210.

[0073] Specifically, referring to Figure 7 The driven end support assembly 140 comprises a second support frame 141 and a plurality of second bearings 142. The second support frame 141 is arranged on the inside of the left side frame 121 and is located on the outside of the left side heat sealing plate 400. The plurality of second bearings 142 are arranged on the second support frame 141 and are used to support the driving end of the ceramic roller 210.

[0074] In the embodiment, the driven end support assembly 140 comprises a second support frame 141 and a plurality of second bearings 142. The second support frame 141 is arranged on the left side frame 121 near the hole brick 300, and the second bearings 142 are installed on the second support frame 141 to support the driven end of the ceramic roller 210. Since the heat insulation sealing plate 400 is arranged outside the hole brick 300, the temperature at the gap 310 of the hole brick 300 can be reduced, and thus the second support frame 141 can be installed on the inner side of the left side frame 121 to reduce the span of the ceramic roller 210.

[0075] Specifically, referring to Figure 8 The roller kiln transmission and cooling system further comprises a driving assembly 500 and a cross shaft universal joint 600, and the driving assembly 500 is drivingly connected with the ceramic roller 210 through the cross shaft universal joint 600. The cross shaft universal joint 600 can ensure that power is stably transmitted from the driving assembly 500 to the ceramic roller 210, reduce the twisting and breaking of the ceramic roller 210 under high-temperature load, and make the ceramic roller 210 run smoothly.

[0076] Referring to Figure 9 The cross shaft universal joint 600 comprises a cross shaft assembly 610, a first universal joint fork 620, and a second universal joint fork 630. One end of the first universal joint fork 620 is rotatably connected with the cross shaft assembly 610, and the other end of the first universal joint fork 620 is fixedly connected with the driving assembly 500. One end of the second universal joint fork 630 is rotatably connected with the cross shaft assembly 610, and the other end of the second universal joint fork 630 is fixedly connected with the ceramic roller 210. The cross shaft universal joint 600 is used for power transmission, and can effectively transmit power between shafts at different angles and flexibly adapt to the change of the included angle between shafts within a certain range. During the operation of the transmission system, the ceramic roller 210 may appear axial displacement due to factors such as temperature change, manufacturing and assembly error of parts, etc. The cross shaft universal joint can compensate for this axial displacement to a certain extent. The driving assembly 500 can be understood as prior art, and the specific structure of the driving assembly 500 will not be described here.

[0077] Specifically, referring to Figure 9The cross shaft assembly 610 comprises a cross shaft sleeve 611, a transverse rotating shaft 612, a longitudinal rotating shaft 613 and a knuckle bearing 614. The cross shaft sleeve 611 has a transverse through hole, a longitudinal through hole, a pair of transverse horizontal planes and a pair of longitudinal horizontal planes. The transverse horizontal planes are used to be embedded in the first knuckle 620 and are in sliding connection with the first knuckle 620. The longitudinal horizontal planes are used to be embedded in the second knuckle 630 and are in sliding connection with the second knuckle 630. The transverse rotating shaft 612 is arranged in the transverse through hole and is used to be in rotational connection with the first knuckle 620. The longitudinal rotating shaft 613 is arranged in the transverse through hole and penetrates the transverse rotating shaft 612. The longitudinal rotating shaft 613 is connected with the transverse rotating shaft 612 to form a cross shaft. The longitudinal rotating shaft 613 is used to be in rotational connection with the second knuckle 630. The knuckle bearing 614 is located between the longitudinal rotating shaft 613 and the second knuckle 630 and is used to realize the rotational connection between the longitudinal rotating shaft 613 and the second knuckle 630.

[0078] In the embodiment, the cross shaft sleeve 611 can provide support and positioning for the transverse rotating shaft 612 and the longitudinal rotating shaft 613, so that the transverse rotating shaft 612 and the longitudinal rotating shaft 613 can better play their roles. Meanwhile, the cross shaft sleeve 611 also plays a role of protecting the transverse rotating shaft 612 and the longitudinal rotating shaft 613 and reducing the wear of the transverse rotating shaft 612 and the longitudinal rotating shaft 613. The knuckle bearing 614 can reduce the friction between the longitudinal rotating shaft 613 and the second knuckle 630, improve the transmission efficiency, and bear the axial and radial loads to ensure the smooth operation of the universal joint during power transmission.

[0079] Specifically, referring to Figure 9 The first knuckle 620 comprises a first connecting base 621 and a first ear holder 622. The first connecting base 621 is used to be fixedly connected with the driving assembly 500. The first ear holder 622 is arranged on the first connecting base 621 and has a first fork hole 623 used to be in rotational connection with the transverse rotating shaft 612.

[0080] In the embodiment, the first fork hole 623 of the first ear holder 622 is sleeved on the journal of the transverse rotating shaft 612 and rotates with the rotation of the transverse rotating shaft 612. This allows the ceramic roller 210 to swing in different directions to adapt to various complex transmissions and ensures the stability of the transmission.

[0081] Specifically, referring to Figure 9The second universal joint fork 630 comprises a second connecting base 631 and a second ear holder 632, the second connecting base 631 is used for fixed connection with the ceramic roller bar 210, and the second ear holder 632 is arranged on the second connecting base 631 and has a second fork hole 633 used for rotation connection with the longitudinal rotation shaft 613.

[0082] In the embodiment, the second fork hole 633 of the second ear holder 632 is sleeved on the shaft neck of the longitudinal rotation shaft 613 and rotates with the rotation of the longitudinal rotation shaft 613, so that the ceramic roller bar 210 can swing in different directions to adapt to various complex transmissions and ensure the stability of the transmission.

[0083] The second universal joint fork 630 and the ceramic roller bar 210 are provided with a roller sleeve 640, and the roller sleeve 640 is integrally formed with the second universal joint fork 630. The structure is simple, easy to realize, can transmit power in the case of changing the angle between the two shafts, and ensures the stable operation of the ceramic roller bar 210.

[0084] Please refer to Figure 8 and Figure 9 The roller sleeve 640 comprises a sleeve body 641, a main roller shaft core 642 and a circlip 643, the sleeve body 641 is integrally formed with the second connecting base 631 of the second universal joint fork 630, the main roller shaft core 642 extends outward from the sleeve body 641 and is used for being embedded in the ceramic roller bar 210, and the circlip 643 is arranged on the outer wall of the sleeve body 641 and extends to one side of the main roller shaft core 642 and is used for abutting against the ceramic roller bar 210.

[0085] In the prior art, the end of the ceramic roller bar 210 is fixed in the inner side of the roller sleeve 640 after being machined, and the ceramic roller bar 210 will deform under the condition of high temperature and heavy load. If the cooperation tolerance between the end of the ceramic roller bar 210 and the roller sleeve 640 is too small, the roller head will be broken, and if the cooperation tolerance cannot be machined, the gap between the end of the ceramic roller bar 210 and the roller sleeve 640 is large, so that the ceramic roller bar 210 is driven to rotate to the high position by the circlip 643 during the transmission operation, and the roller falls, resulting in unstable operation.

[0086] In the embodiment, the main roller shaft core 642 is embedded in the ceramic roller bar 210, which is equivalent to that the ceramic roller bar 210 is sleeved on the main roller shaft core 642 and is clamped by the circlip 643. The circlip 643 plays a connecting and fixing role, is clamped at the end of the ceramic roller bar 210, prevents the displacement of the roller in the axial direction, makes the ceramic roller bar 210 always abut against the main roller shaft core 642, and ensures the stable operation of the ceramic roller bar 210.

[0087] The ceramic roller bar 210 in the embodiment has stable transmission operation, and compared with the transmission system of the traditional building ceramic roller kiln, the span of the ceramic roller bar 210 can be reduced by at least 400 mm under the condition of the same kiln width, the selection range of the ceramic roller bar 210 is widened, the load deformation of the ceramic roller bar 210 is greatly reduced, the product deformation range is reduced, and the product quality is improved.
