In order to increase production and reduce the energy consumption of the annealing furnace, a layer of heat-insulating refractory material is sprayed on the surface of the annealing furnace to improve its heat insulation performance.

[0003] For example, patent application number CN200510017988.3 discloses a high-temperature resistant composite thermal insulation spray coating suitable for high-temperature kilns or other irregularly shaped or rotating thermal equipment. It is made from sepiolite, brucite, crocidolite, basalt, andalusite, and quartz as base materials, and high-temperature resistant binder powder, pre-prepared into a dry powder form, and then mixed with water on-site. This thermal insulation spray coating has a low thermal conductivity, good thermal insulation performance, high bonding strength, can be applied both hot and cold, is easy to cure, has low overall cost, and is convenient to apply. However, this type of thermal insulation coating requires the use of spray guns, which are often handheld. On-site spraying requires operators to hold the gun around the kiln, which can lead to uneven coating thickness in overlapping areas, affecting the thermal insulation performance.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a thermal insulation material spraying device, including a rotating bracket. A movable arm 3 is rotatably provided at the lower end of the rotating bracket. An adjustment block 5 is provided at each of the left and right ends of the movable arm 3. The adjustment block 5 is slidably connected to the movable arm 3. A sliding control mechanism for adjusting the distance between the two adjustment blocks 5 is provided on the outside of the movable arm 3.

[0024] The lower end of the movable arm 3 is provided with a positioning rod 9, which is rotatably set at the center of the movable arm 3. A spraying rod 10 is provided below the adjusting block 5, and several spray nozzles 11 are provided on the side of the two spraying rods 10 facing the positioning rod 9.

[0025] The furnace body requiring insulation coating is placed below the movable arm 3. The positioning rod 9 is aligned with the furnace body's axis, serving as a centering point. An external pump draws paint into the spraying rod 10 via a hose, and then sprays it out from the nozzle 11 on the outside of the spraying rod 10. A rotating bracket controls the movable arm 3 to rotate forward and backward, spraying the furnace body surface. The hose connected to the spraying rod 10 is of a certain length, capable of supporting one full rotation of the movable arm 3. During the rotation of the movable arm 3, the hose will not become entangled with the movable arm 3 or the spraying rod 10. The specific structure will not be described in detail here.

[0026] A reciprocating transmission component 8 is provided between the adjusting block 5 and the spraying rod 10. The reciprocating transmission component 8 is fixedly installed at the lower end of the adjusting block 5, and the lower end of the reciprocating transmission component 8 is fixedly connected to the upper end of the spraying rod 10 to push the spraying rod 10 to swing vertically back and forth.

[0027] During the rotation of the movable arm 3, the distance between the two adjusting blocks 5 can be changed by the sliding control mechanism, thereby adjusting the distance between the spraying rod 10 and the furnace body to adapt to annealing furnaces of different sizes. While having a wide range of applications, the reciprocating transmission component 8 fixed at the lower end of the adjusting block 5 can push the spraying rod 10 to swing vertically back and forth during the spraying process. The spraying rod 10 then drives the spray head 11 to swing synchronously, improving the uniformity of paint spraying and improving heat preservation performance.

[0028] Regarding the rotating bracket:

[0029] The rotating support includes a mounting plate 1, with a reversible motor 2 mounted on the upper end of the mounting plate 1. The reversible motor 2 is fixedly connected to the mounting plate 1, and its output end passes through the mounting plate 1 and is fixedly connected to the movable arm 3. Several fixing bolts are fitted along the edge of the mounting plate 1. The mounting plate 1 is fixed to the external frame by the fixing bolts. During spraying, the furnace body to be coated with the insulation layer is placed below the movable arm 3, between the two spraying rods 10. The reversible motor 2 controls the movable arm 3 to rotate one revolution forward and then one revolution backward, repeating this process to complete the spraying of the furnace body insulation coating.

[0030] Regarding reciprocating transmission component 8:

[0031] The reciprocating transmission component 8 includes a mounting base 81, which is fixedly mounted on the lower end of the adjusting block 5. A movable plate 84 is provided on one side of the mounting base 81, and the movable plate 84 is slidably connected to the mounting base 81. An eccentric wheel 86 is provided at the lower end of the movable plate 84, and the eccentric wheel 86 is fixedly mounted on the upper end of the spraying rod 10. An eccentric wheel groove 85 is formed in the center of the movable plate 84, and the eccentric wheel 86 is rotatably mounted within the eccentric wheel groove 85. A second motor 87 for controlling the rotation of the eccentric wheel 86 is provided on the side of the mounting base 81 away from the movable plate 84. The reciprocating transmission component 8 uses an eccentric wheel transmission method to drive the spraying rod 10 to reciprocate. Specifically, the second motor 87 controls the eccentric wheel 86 to rotate within the eccentric wheel groove 85. The eccentric wheel 86, in cooperation with the eccentric wheel groove 85, pushes the movable plate 84 up and down from the inside of the movable plate 84. During this oscillation, the movable plate 84 drives the spraying rod 10 to oscillate synchronously via the eccentric wheel 86.

[0032] It is worth explaining in detail that a guide rail 83 is laid on the outer side of the mounting base 81, and a slider 82 is slidably mounted on the guide rail 83. The slider 82 is fixedly connected to the movable plate 84. The guide rail 83 guides the movable plate 84 by cooperating with the slider 82.

[0033] It is worth explaining in detail that the lower end of the movable arm 3 is provided with an adjustment groove 4, and the adjustment block 5 is slidably disposed inside the adjustment groove 4. The adjustment groove 4 guides the adjustment block 5 by cooperating with it.

[0034] Regarding the slip control mechanism:

[0035] The sliding control mechanism includes a double-headed screw 6, which is rotatably mounted inside the adjusting groove 4. The left and right ends of the double-headed screw 6 are threadedly connected to two adjusting blocks 5 respectively. A first motor 7 is fixedly mounted on the outside of the movable arm 3, and the output shaft of the first motor 7 is fixedly connected to the double-headed screw 6.

[0036] The first motor 7 starts and controls the double-headed screw 6 to rotate. As the double-headed screw 6 rotates, it cooperates with two adjusting blocks 5, causing the two adjusting blocks 5 to slide along the adjusting groove 4. The double-headed screw 6 has two threads on the outside of the shaft, and the two threads cooperate. Since the threads are in opposite directions, when the double-headed screw 6 rotates, the two adjusting blocks 5 will move in opposite directions along the shaft of the double-headed screw 6.

[0037] To prevent paint from seeping through the adjustment groove 4 at the bottom of the movable arm 3 and falling onto the surface of the double-ended screw 6 during the spraying process, thus affecting the movement of the adjustment block 5, the lower end of the movable arm 3 is equipped with multiple accordion-style covers 12. The accordion-style covers 12 are fixedly installed at both ends of the adjustment block 5, with the end of the accordion-style cover 12 furthest from the adjustment block 5 fixedly installed on the lower end face of the movable arm 3. The accordion-style covers 12 have several pleats, allowing them to move in sync with the adjustment block 5, unfolding and retracting. During this unfolding and retraction process, the accordion-style covers 12 completely cover the adjustment groove 4, protecting the double-ended screw 6.

[0038] How this application works:

[0039] The furnace body requiring insulation coating is placed below the movable arm 3. An external pump draws paint into the spraying rod 10 through a hose, and then sprays it out from the nozzle 11 on the outside of the spraying rod 10. The rotating bracket controls the forward and reverse rotation of the movable arm 3 to spray the furnace surface. During the rotation of the movable arm 3, the distance between the two adjusting blocks 5 is changed through the sliding control mechanism, adjusting the distance between the spraying rod 10 and the furnace body to adapt to annealing furnaces of different sizes. While having wide applicability, the reciprocating transmission component 8 fixed at the lower end of the adjusting block 5 can push the spraying rod 10 to swing vertically back and forth during the spraying process. The spraying rod 10 then drives the nozzle 11 to swing synchronously, improving the uniformity of paint spraying and improving insulation performance.
