[0024] In order to more clearly understand the technical solutions shown in the embodiments of the present application, first, the structure and working principle of the existing automatic wet material spraying device for buried kiln refractory will be introduced.

The kiln refractory wet material automatic spraying device with this structure is used by first crossing the moving base frame at the mouth of the buried kiln, and under the action of the lifting mechanism, the spraying head and the rotating mechanism are extended into the kiln. Then, the spraying head is connected with the refractory wet material pumping pipe, and under the action of the rotating mechanism, the spraying head is rotated, so as to spray the refractory wet material into the inner wall of the buried kiln during the rotation of the spraying head.
[0026] Please refer to Figures 1-4The application discloses a kind of kiln refractory wet material automatic spraying device disclosed in the embodiment of the application, including chassis 2, the middle part of the upper end of chassis 2 is welded with a inverted U-shaped support 1, the top middle part of support 1 is equipped with lifting mechanism 6, lifting mechanism 6 includes motor one 61, screw one 62, linkage plate 63, slide rod 64 and lifting plate 65, the middle part of lifting plate 65 is equipped with inverted T-shaped connecting pipe 11, rotating mechanism 12 is installed on lifting plate 65 at connecting pipe 11, rotating mechanism 12 includes motor two 121, fixed frame 122, gear one 123 and gear two 124, two spray heads 4 are staggered arranged at the two ends of connecting pipe 11, a uniform material assembly 9 is installed on one side of each spray head 4 on connecting pipe 11, uniform material assembly 9 includes uniform material roller 91, roller frame 92, connecting rod 93, connecting plate 94, adjusting bolt 95 and adjusting sleeve 96, a discharge port 7 is formed in connecting pipe 11 opposite each spray head 4, linkage adjusting mechanism 8 is installed between two spray heads 4 on connecting pipe 11, linkage adjusting mechanism 8 includes block plug 81, hanger plate 82, linkage rod 83, motor three 84 and screw two 85, wherein connecting plate 94 is slidingly installed on spray head 4, adjusting sleeve 96 is welded with connecting plate 94, adjusting bolt 95 is installed on the peripheral sidewall of adjusting sleeve 96, connecting rod 93 is connected to the sidewall of connecting plate 94 away from adjusting sleeve 96, roller frame 92 is connected to one end of connecting rod 93 away from connecting plate 94, uniform material roller 91 is installed on roller frame 92;Two hanger plates 82 are symmetrically installed on the two sides of the bottom end of connecting pipe 11, screw two 85 is installed between hanger plate 82, motor three 84 is installed on the outer wall of one hanger plate 82, linkage rod 83 is installed on screw two 85, block plug 81 is installed on the two ends of linkage rod 83 matched with connecting pipe 11, rotating joint 10 is further installed on the top end of connecting pipe 11, wet material pumping pipe 5 is connected to the upper side of rotating joint 10.
[0027] Specifically, when spraying the refractory wet material inside the previous kiln, first, the base frame 2 is moved to the upper side of the embedded kiln, and the center of the connecting pipe 11 is aligned with the center of the kiln. Then, the position of the material uniformizing roller 91 is adjusted by sliding the adjusting sleeve 96 on the spraying head 4, to ensure that a certain gap for the adhesion of the refractory wet material is reserved between the material uniformizing roller 91 and the inner wall of the kiln. Then, the wet material pumping pipe 5 is connected to the external refractory wet material pumping equipment, and the gear one 123 and the gear two 124 are driven to rotate by the motor two 121 in the rotating mechanism 12, so that the connecting pipe 11 and the spraying head 4 rotate synchronously with the gear two 124, to ensure the rotation of the refractory wet material on the inner wall of the kiln. During the spraying process, the position of the spraying head 4 is adjusted layer by layer by the lifting mechanism 6, to realize the complete spraying of the refractory wet material to all parts of the inner wall of the kiln. During the spraying process, the material uniformizing roller 91 will smooth and flatten the refractory wet material sprayed on the inner wall of the kiln. When one spraying head 4 is blocked and cannot be used normally during the spraying process, the screw rod two 85 can be driven to rotate by the motor three 84, and the linkage rod 83 will slide along the connecting pipe 11 after the screw rod two 85 is rotated, so that the unused spraying head 4 is connected to the feeding end of the connecting pipe 11 under the action of the blockage 81, while the blocked spraying head 4 is separated from the feeding end of the connecting pipe 11 under the action of the corresponding blockage 81, to realize the alternate use of the two spraying heads 4, ensure the normal working time of the device, and facilitate the efficient spraying of the refractory wet material.
[0028] Please refer to Figure 1 and Figure 3 , the spraying head 4 penetrates the adjusting sleeve 96 and is in sliding fit with the adjusting sleeve 96, and the adjusting bolt 95 is in threaded connection with the adjusting sleeve 96.
[0029] As an embodiment, after the adjusting bolt 95 is loosened, the adjusting sleeve 96 can slide conveniently along the outer wall of the spraying head 4, to ensure that the material uniformizing roller 91 can be close to the inner wall of the kiln when in use.
[0030] Please refer to Figure 1 and Figure 3 , one end of the connecting rod 93 is bolted to the connecting plate 94, the other end of the connecting rod 93 is welded to the roller frame 92, and the material uniformizing roller 91 is in rotational fit with the roller frame 92.
[0031] As an embodiment, the connecting rod 93 is a bending type mechanism, which is mainly used to realize the convenient connection of the roller frame 92 and the connecting plate 94, and at the same time, the roller frame 92 is staggered with the spraying head 4, to avoid blocking the normal spraying of the spraying head 4.
[0032] Please refer to Figures 1-2 , the screw rod two 85 penetrates the boss in the middle of the linkage rod 83 and is in threaded connection with the boss on the linkage rod 83.
[0033] In one implementation, after the screw 85 rotates, the linkage 83 will slide along the bottom of the connecting pipe 11 under the action of the threaded transmission.
[0034] Please see Figures 1-2 The two ends of the linkage rod 83 are bonded to the sealing plug 81, and the sealing plug 81 is in sliding fit with the connecting pipe 11.
[0035] As one implementation, the sealing plug 81 can slide relative to the connecting pipe 11, and can also seal the connecting pipe 11 after it stops moving, so as to ensure that the two nozzles 4 can be connected as needed.
[0036] Please see Figures 1-2 Motor 3 84 is connected to screw 2 85 by a coupling, and screw 2 85 is rotatably engaged with hanging plate 82.
[0037] In one implementation method, motor 3 84 is mainly used to provide power for the rotation of screw 2 85. The rotational installation method can ensure convenient rotational adjustment of screw 2 85 relative to hanging plate 82.
[0038] Please see Figure 1 Motor 61 is installed at the top center of bracket 1. Screw 62 is connected to the power output end of motor 61. Linkage plate 63 is installed on screw 62. There are two slide rods 64, and the two slide rods 64 are symmetrically installed at the bottom of linkage plate 63. Lifting plate 65 is connected to the bottom of slide rod 64.
[0039] In one implementation, after the motor 61 drives the screw 62 to rotate, the linkage plate 63 will move down under the action of the screw drive. After the linkage plate 63 moves down, the lifting plate 65 will move down with the help of the slide rod 64. After the lifting plate 65 moves down, the height of the spray head 4 will be adjusted layer by layer, so that the spray head 4 will rotate and descend layer by layer to completely spray the inner wall of the kiln.
[0040] Please see Figure 1 and Figure 1 The fixed frame 122 has an inverted L-shaped structure. The fixed frame 122 is installed on the upper end of the lifting plate 65. The second motor 121 is installed on one side of the top of the fixed frame 122. The first gear 123 is connected to the power output end of the second motor 121. The second gear 124 is installed on the upper part of the connecting pipe 11. The first gear 123 meshes with the second gear 124.
[0041] In one implementation, the motor 121 drives the gear 123 to rotate, which in turn causes the gear 124 to rotate. The rotation of the gear 124 then drives the connecting pipe 11 to rotate, which in turn drives the spray head 4 to rotate, thereby achieving automatic rotation of the spray head 4 during spraying.
[0042] Please see Figure 1Each of the four corners of the bottom of the base frame 2 is equipped with a brakeable universal wheel 3.
[0043] As one implementation method, the casters 3 enable the base frame 2 to move flexibly, ensuring that the device can be easily moved to the upper side of different pre-embedded kilns.
[0044] The specific working principle is as follows: When spraying refractory wet material inside the kiln, the base frame 2 is first moved to the upper side of the pre-embedded kiln, and the center of the connecting pipe 11 is aligned with the center of the kiln. Then, the position of the uniform roller 91 is adjusted by sliding the adjusting sleeve 96 on the spray head 4 to ensure that a certain gap for the adhesion of the refractory wet material is left between the uniform roller 91 and the inner wall of the kiln. Next, the wet material pumping pipe 5 is connected to the external refractory wet material pumping equipment, and the gear 1 is driven by the motor 121 in the rotating mechanism 12. The rotation of gears 123 and 124 ensures the synchronous rotation of connecting pipe 11 and spray head 4 with gear 124, guaranteeing the rotational spraying of wet refractory material onto the kiln wall. During the spraying process, the position of spray head 4 is adjusted layer by layer under the action of lifting mechanism 6, thereby achieving complete spraying of wet refractory material onto all parts of the kiln wall. During the spraying process, the leveling roller 91 evenly smooths the wet refractory material sprayed onto the kiln wall. However, if one spray head 4 becomes blocked and cannot function properly during the spraying process... In use, the screw 85 can be rotated by the motor 84. After the screw 85 rotates, the linkage rod 83 will slide along the connecting pipe 11, thereby connecting the unused spray head 4 to the feed end of the connecting pipe 11 under the action of the sealing plug 81. The blocked spray head 4 will be separated from the feed end of the connecting pipe 11 under the action of the corresponding sealing plug 81, thereby realizing the alternating use of the two spray heads 4, ensuring the normal working time of the device, and facilitating the efficient spraying of refractory wet material. During the above spraying process, the uniform material component 9 realizes the uniform smoothing of the refractory wet material sprayed on the inner wall of the kiln, thereby ensuring that the thickness of the refractory wet material is consistent in all places on the inner wall of the kiln, and ensuring the spraying quality of the refractory wet material. At the same time, the two spray heads 4 on the connecting pipe 11 can be used alternately through the linkage adjustment mechanism 8. When one spray head is blocked, the other intact spray head can be used normally through the linkage adjustment, thereby effectively extending the normal working time of the equipment and improving the spraying efficiency of the refractory wet material on the inner wall of the kiln.
[0045] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
