Description

Technical Field

[0001] This utility model belongs to the field of kiln construction technology, specifically relating to a refractory wet material dressing device for kiln construction. Background Technology

[0002] The refractory wet refractory coating device for kiln construction is a key piece of equipment in kiln construction. Its design must meet the requirements of the wet spraying process of refractory materials to ensure construction efficiency, quality and safety. Its main function is to transport the mixed refractory wet material through a conveying device and spray it onto the inner wall of the kiln through the refractory wet refractory coating device.

[0003] In the field of kiln construction, the traditional method of applying wet refractory coatings to vertical cylindrical kilns is still primarily manual. Operators must hold spray guns and work for extended periods in the confined and high-temperature environment inside the kiln. This method is not only inefficient and unsuitable for large-scale industrial production, but also poses significant occupational health and safety hazards because the wet refractory coating process generates a large amount of fine particulate matter. Long-term accumulation of these harmful substances can cause serious damage to the respiratory system and lungs. Utility Model Content

[0004] The purpose of this utility model is to provide a refractory wet material coating device for kiln construction, which aims to solve the problem that the current refractory wet material coating device for kiln construction usually adopts manual spraying when spraying refractory wet material on vertical cylindrical kilns. This not only leads to low efficiency, but also makes it easy for operators to inhale the refractory wet material and cause physical injury.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a refractory wet material application device for kiln construction, comprising a shell and a nozzle, wherein a first bearing is fitted and installed on the bottom side of the shell, a bent pipe inserted into the shell is connected through the interior of the first bearing, the nozzle is connected to the end of the bent pipe, a sealed bearing is sleeved on the surface of the bent pipe located inside the shell, a connecting pipe connected through the upper surface of the shell is sleeved on the surface of the sealed bearing, and a drive assembly connected to the bent pipe is installed through the interior of the shell.

[0006] As a refractory wet material dressing device for kiln construction according to the present invention, preferably, the driving component includes a first driving motor that is connected through to the upper surface of the shell, the output end of the first driving motor is connected to a driving gear, and the surface of the bent tube is connected to a driven gear that meshes with the driving gear.

[0007] As a refractory wet material covering device for kiln construction according to the present invention, preferably, a support component is connected to the side surface of the shell, and a walking component is installed at the end of the support component away from the shell. The support component and the walking component are arranged in three sets in a ring array on the side surface of the shell.

[0008] As a preferred embodiment of the refractory wet material covering device for kiln construction, the support assembly includes a support pipe, an extension pipe, and an electric telescopic rod. The support pipe is connected to the side surface of the shell, and an extension pipe of a suitable size is fitted onto the surface of the support pipe. An electric telescopic rod connected to the inner wall of the extension pipe is installed inside the support pipe.

[0009] As a refractory wet material covering device for kiln construction according to the present invention, preferably, the support component further includes a guide strip and a guide groove, the guide strip is connected to the inner wall of the extension tube, and the surface of the support tube is provided with a guide groove adapted to the size of the extension tube.

[0010] As a preferred embodiment of the refractory wet material covering device for kiln construction, the walking assembly includes a support, a second bearing, a horizontal shaft, and a walking wheel. The support is connected to the end of the extension tube. Two second bearings are fitted onto the surface of the support. A horizontal shaft passes through the interior of the two second bearings. A walking wheel is connected to each end of the horizontal shaft.

[0011] As a refractory wet material covering device for kiln construction according to the present invention, preferably, the walking component further includes a driven bevel gear, a second drive motor and a driving bevel gear. The driven bevel gear is connected to the surface of the horizontal shaft, the second drive motor is installed on the inner wall of the bracket, and the movable end of the second drive motor is connected to the driving bevel gear that meshes with the driven bevel gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, the second drive motor drives the active bevel gear to rotate during operation. When the active bevel gear rotates, it drives the driven bevel gear to rotate. When the driven bevel gear rotates, it drives the traveling wheel to rotate through the horizontal shaft. In this way, the traveling component can move longitudinally along the inner wall of the vertical cylindrical kiln through the rotation of the traveling wheel. At the same time, the drive component can achieve 360° rotation of the bent pipe. This can be combined with the nozzle to spray refractory wet material 360° to achieve full coverage of refractory wet material application on the inner wall of the vertical cylindrical kiln, thereby improving the efficiency of refractory wet material application on the inner wall of the vertical cylindrical kiln.

[0014] Furthermore, the position of the walking component can be adjusted by setting up the support components, so that the device can adapt to vertical cylindrical kilns with different inner wall diameters, thereby improving the applicability of the device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-8 The present invention provides the following technical solution: a refractory wet material application device for kiln construction, comprising a shell 1 and a nozzle 4, a first bearing 2 is fitted and installed on the bottom side of the shell 1, a bent pipe 3 inserted into the shell 1 is connected through the inside of the first bearing 2, the nozzle 4 is connected to the end of the bent pipe 3, a sealed bearing 6 is sleeved on the surface of the bent pipe 3 located inside the shell 1, a connecting pipe 7 is sleeved on the surface of the sealed bearing 6 and connected through the upper surface of the shell 1, and a drive assembly 5 connected to the bent pipe 3 is installed through the inside of the shell 1.

[0027] Preferably, the drive assembly 5 includes a first drive motor 501 that is connected through to the upper surface of the housing 1, the output end of the first drive motor 501 is connected to a drive gear 502, and the surface of the bent tube 3 is connected to a driven gear 503 that meshes with the drive gear 502.

[0028] In practical use, when the first drive motor 501 is running, it can drive the active gear disk 502 to rotate. When the active gear disk 502 rotates, it can drive the driven gear disk 503 to rotate through the meshing structure. When the driven gear disk 503 rotates, it can drive the bent pipe 3 to rotate inside the first bearing 2. When the bent pipe 3 rotates, it can drive the nozzle 4 to rotate.

[0029] Preferably, a support assembly 8 is connected to the side surface of the housing 1, and a walking assembly 9 is installed at the end of the support assembly 8 away from the housing 1. The support assembly 8 and the walking assembly 9 are arranged in three sets in a ring array on the side surface of the housing 1.

[0030] Preferably, the support assembly 8 includes a support tube 801, an extension tube 802 and an electric telescopic rod 805. The support tube 801 is connected to the side surface of the housing 1. The surface of the support tube 801 is fitted with an extension tube 802 that is adapted to its size. The inside of the support tube 801 is equipped with an electric telescopic rod 805 that is connected to the inner wall of the extension tube 802.

[0031] In practical use, when the electric telescopic rod 805 is running, it can squeeze the extension tube 802. When the extension tube 802 is squeezed, it can move away from the support tube 801, which can adjust the overall length of the support assembly 8.

[0032] Preferably, the support assembly 8 further includes a guide bar 803 and a guide groove 804. The guide bar 803 is connected to the inner wall of the extension tube 802, and the surface of the support tube 801 is provided with a guide groove 804 that is adapted to the size of the extension tube 802.

[0033] In practical use, when the extension tube 802 extends, it can drive the guide strip 803 to slide on the surface of the guide groove 804. This can limit the extension direction of the extension tube 802, thereby maintaining the stability of the extension tube 802 during movement.

[0034] Preferably, the walking assembly 9 includes a bracket 901, a second bearing 902, a horizontal shaft 903, and a walking wheel 904. The bracket 901 is connected to the end of the extension tube 802. Two second bearings 902 are fitted onto the surface of the bracket 901. A horizontal shaft 903 passes through the interior of the two second bearings 902. A walking wheel 904 is connected to each end of the horizontal shaft 903.

[0035] Preferably, the walking assembly 9 also includes a driven bevel gear 905, a second drive motor 906 and a driving bevel gear 907. The driven bevel gear 905 is connected to the surface of the horizontal shaft 903. The second drive motor 906 is installed on the inner wall of the bracket 901. The movable end of the second drive motor 906 is connected to the driving bevel gear 907 that meshes with the driven bevel gear 905.

[0036] In practical use, when the second drive motor 906 is running, it can drive the active bevel gear 907 to rotate. When the active bevel gear 907 rotates, it can drive the driven bevel gear 905 to rotate through the meshing structure. When the driven bevel gear 905 rotates, it can drive the horizontal shaft 903 to rotate. When the horizontal shaft 903 rotates, it can drive the traveling wheel 904 to rotate.

[0037] The working principle of this utility model in specific use is as follows: When using this device, first suspend it to the bottom of the vertical cylindrical kiln. Then, the electric telescopic rod 805 can be operated. When the electric telescopic rod 805 is running, it can squeeze the extension tube 802 to move away from the support tube 801. When the support tube 801 drives the walking wheel 904 of the walking component 9 to move to the inner wall of the kiln, the pipe of the external spraying device can be connected to the connecting pipe 7. The refractory wet material is entered into the bent pipe 3 through the connecting pipe 7 and sprayed out from the nozzle 4 through the spraying device, thereby realizing the spraying of refractory wet material on the inner wall of the kiln.

[0038] Next, the first drive motor 501 can be run. When the first drive motor 501 is running, it can drive the active gear disk 502 to rotate. When the active gear disk 502 rotates, it drives the bent pipe 3 to rotate through the driven gear disk 503. When the bent pipe 3 rotates, it can drive the spray head 4 to rotate, thus realizing 360° spraying of refractory wet material.

[0039] At the same time, the second drive motor 906 can be operated. When the second drive motor 906 is running, it can drive the active bevel gear 907 to rotate. When the active bevel gear 907 rotates, it drives the driven bevel gear 905 to rotate. When the driven bevel gear 905 rotates, it drives the traveling wheel 904 to rotate through the horizontal shaft 903. In this way, the traveling component 9 can move longitudinally on the inner wall of the vertical cylindrical kiln through the rotation of the traveling wheel 904. In combination with the 360° spraying of the spray nozzle 4, the refractory wet material covering the entire vertical cylindrical kiln can be achieved.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
