Description

Technical Field

[0001] This utility model belongs to the technical field of spraying equipment, specifically relating to a peripheral high-temperature nano-coating spraying equipment. Background Technology

[0002] In high-temperature industrial environments, circumferential high-temperature nano-coating spraying equipment plays a crucial role in protecting the inner walls of furnaces and kilns in high-temperature equipment. However, the inner wall diameters of different types of furnaces in industrial production vary significantly. Traditional equipment uses fixed-size annular spraying pipes, typically welded to the equipment, which limits its adaptability to furnaces of different diameters. It cannot easily replace the appropriate annular spraying pipe according to the furnace size to ensure the spraying distance and effectiveness with the furnace inner wall. Therefore, a circumferential high-temperature nano-coating spraying equipment is proposed to solve the aforementioned technical problems. Summary of the Invention

[0003] In existing spraying equipment, the annular spraying pipes are typically connected to the equipment by welding. This presents problems such as inconvenience in replacing the appropriate annular spraying pipes according to the furnace size, and difficulty in ensuring the spraying distance and effect with the furnace inner wall. This invention provides a circumferential high-temperature nano-coating spraying device. When spraying furnaces of different sizes, an adjustable-length lifting mechanism can accommodate the installation of annular spraying pipes of different sizes, facilitating replacement and ensuring the spraying distance and effect with the furnace inner wall. The replacement operation is simple; only the length of the lifting mechanism needs to be adjusted, and the annular spraying pipe can be fixed with bolt B and a limit clip. This effectively solves the problem of existing spraying equipment where the annular spraying pipes are typically connected to the equipment by welding, making it difficult to replace the appropriate annular spraying pipes according to the furnace size and ensuring the spraying distance and effect with the furnace inner wall. The specific technical solution is as follows:

[0004] A high-temperature nano-coating spraying device for a periphery includes a cover plate. A vertical lifting mechanism is installed on the lower surface of the cover plate. Lifting mechanisms capable of telescopic adjustment of lifting position are fixedly installed on both the front and rear sides of the vertical lifting mechanism. An annular spraying pipe is detachably installed between the outer ends of the two lifting mechanisms. A telescopic feeding block is installed between the feed end of the annular spraying pipe and the cover plate. The lower end of the telescopic feeding block is threadedly connected to the feed end of the annular spraying pipe. The upper end of the telescopic feeding block penetrates the upper surface of the cover plate. A hot air supply connection port is provided through the upper surface of the cover plate. An internal clamping positioning mechanism is fixedly installed on the lower surface of the cover plate.

[0005] In the above technical solution, both lifting mechanisms include fixed rods, which are respectively fixedly installed on the front and rear sides of the vertical lifting mechanism. Each fixed rod has a through groove, and a movable rod is slidably installed in each groove. Bolts A for abutting the movable rod are threaded through the upper surface of each fixed rod. Lifting grooves are opened on the upper surface of the outer end of each movable rod, and the annular spray tube is placed in the lifting groove. Limiting clips are rotatably installed on the outer end of each movable rod, and bolts B are threaded between the limiting clips and the corresponding movable rods.

[0006] In the above technical solution, an L-shaped bracket is slidably installed on the lower surface of each movable rod, and an annular scraper is installed between two L-shaped brackets. The upper surface of the annular scraper is in contact with the lower surface of the movable rod. Bolts C are screwed between each L-shaped bracket and the corresponding movable rod, and each bolt C passes through the mounting hole of the annular scraper.

[0007] In the above technical solution, the lower surface of the movable rod is provided with a T-shaped groove, and the upper surface of the L-shaped bracket is fixedly installed with a T-shaped slider. The T-shaped slider is slidably installed in the corresponding T-shaped groove to realize the sliding connection between the L-shaped bracket and the movable rod.

[0008] In the above technical solution, the vertical lifting mechanism includes two vertical rods, a base, a lead screw, a lead screw motor, and a lead screw slide. The two vertical rods are symmetrically fixedly installed on the lower surface of the cover plate. The base is fixedly installed between the lower surfaces of the two vertical rods. The lead screw is rotatably installed between the base and the cover plate. The lead screw motor is fixedly installed on the upper surface of the cover plate, and the output end of the lead screw motor is fixedly connected to the top end of the lead screw. The lead screw slide is sleeved on the outer surface of the lead screw, and the lead screw slide is vertically slidably installed between the two vertical rods. The two fixed rods are respectively fixedly connected to the front and rear surfaces of the lead screw slide.

[0009] In the above technical solution, the inner clamping positioning mechanism includes two electric telescopic rods. The two electric telescopic rods are fixedly installed symmetrically on the lower surface of the cover plate with the center of the cover plate as the central axis, and rubber contact blocks are fixedly installed on the opposite ends of the two electric telescopic rods.

[0010] In the above technical solution, handles are symmetrically fixedly installed on the upper surface of the cover plate.

[0011] In the above technical solution, the annular scraper is made of tungsten steel.

[0012] The peripheral high-temperature nano-coating spraying equipment of this utility model has the following advantages compared with the prior art:

[0013] When performing spraying operations on furnaces of different sizes, this utility model can adapt to the installation of annular spraying pipes of different sizes through an adjustable length lifting mechanism, making it convenient to replace and ensuring the spraying distance and effect with the inner wall of the furnace. Moreover, the replacement operation is simple, only requiring adjustment of the length of the lifting mechanism and then fixing the annular spraying pipe with bolt B and limit clip.

[0014] This invention involves sliding an L-shaped bracket onto the lower surface of a movable rod, and mounting a ring scraper between the two L-shaped brackets via bolt C. Before spraying, the ring scraper can be driven by a vertical lifting mechanism to pre-scrape impurities from the inner wall of the annular furnace, preventing impurities from adversely affecting the spraying effect. Furthermore, the ring scraper can be easily replaced by sliding the L-shaped bracket inward after removing bolt C. Combined with the adjustment of the lifting mechanism, an appropriately sized ring scraper can be selected according to different furnace sizes, thus meeting diverse application needs.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-7 This utility model provides a technical solution:

[0025] A high-temperature nano-coating spraying device includes a cover plate 1. A vertical lifting mechanism is installed on the lower surface of the cover plate 1. Lifting mechanisms 3, which can be telescopically adjusted, are fixedly installed on both the front and rear sides of the vertical lifting mechanism. An annular spraying pipe 4 is detachably installed between the outer ends of the two lifting mechanisms 3. A telescopic feeding pipe 41 is installed between the feed end of the annular spraying pipe 4 and the cover plate 1. The lower end of the telescopic feeding pipe 41 is threadedly connected to the feed end of the annular spraying pipe 4. The upper end of the telescopic feeding pipe 41 penetrates the upper surface of the cover plate 1. A hot air supply connection port 6 is provided through the upper surface of the cover plate 1. An internal clamping positioning mechanism 7 is fixedly installed on the lower surface of the cover plate 1. Before using this spraying device, it is necessary to connect an external hot air blower through the hot air supply connection port 6 via an external air guide pipe, and to connect a high-pressure feeder of an external collection box through the feed end of the telescopic feeding pipe 41.

[0026] It should be noted that both lifting mechanisms 3 include fixed rods 31, which are fixedly installed on the front and rear sides of the vertical lifting mechanism respectively. Each fixed rod 31 has a through groove 311, and a movable rod 32 is slidably installed in each groove 311. The upper surface of each fixed rod 31 is threaded with a bolt A312 for pressing against the movable rod 32. The upper surface of the outer end of each movable rod 32 has a lifting groove 321, and the annular spray tube 4 is placed in the lifting groove 321. The outer end of each movable rod 32 is rotatably installed with a limit card 33. The limit card 33 and the corresponding movable rod 32 are threaded with a bolt B331. After the limit card 33 is fastened above the lifting groove 321 and fixed with the bolt B331, the annular spray tube 4 is clamped and fixed.

[0027] When applying high-temperature nano-coatings to furnace inner walls of different sizes, bolt A312 can be loosened, and the position of the sliding adjustment rod 32 within the slide groove 311 can be adjusted. The lifting groove 321 can then be positioned below the corresponding annular spray pipe 4. After placing the annular spray pipe 4 within the lifting grooves 321 on both sides, the limiting clip 33 can be flipped and fastened above the annular spray pipe 4. Finally, bolt B331 can be used to secure the annular spray pipe 4, clamping it between the limiting clip 33 and the lifting groove 321 to complete the installation. Compared to existing technologies, this spraying equipment, through its adjustable-length lifting mechanism 3, can adapt to the installation of annular spray pipes 4 of different sizes when spraying furnaces of different sizes, facilitating replacement and ensuring the optimal spraying distance and effect to the furnace inner wall.

[0028] Before the spraying operation, in order to prevent impurities adhering to the inner wall of the furnace from affecting the spraying effect of the high-temperature nano-coating, L-shaped brackets 34 are slidably installed on the lower surface of the movable rod 32. An annular scraper 5 is installed between the two L-shaped brackets 34. The upper surface of the annular scraper 5 is in contact with the lower surface of the movable rod 32. Bolts C341 are screwed between the L-shaped brackets 34 and the corresponding movable rods 32. The bolts C341 pass through the mounting holes of the annular scraper 5. Before the spraying operation, the vertical lifting mechanism can be used to drive the annular scraper 5 to move down and scrape off the impurities on the inner wall of the annular furnace in advance to prevent the impurities from having an adverse effect on the spraying effect.

[0029] like Figure 4 As shown, the lower surface of the movable rod 32 is provided with T-shaped grooves 322, and the upper surface of the L-shaped bracket 34 is fixedly installed with T-shaped sliders 342. The T-shaped sliders 342 are slidably installed in the corresponding T-shaped grooves 322 to realize the sliding connection between the L-shaped bracket 34 and the movable rod 32.

[0030] like Figure 2 As shown, the vertical lifting mechanism includes two vertical rods 11, a base 12, a lead screw 2, a lead screw motor 21, and a lead screw slide 22. The two vertical rods 11 are symmetrically fixedly installed on the lower surface of the cover plate 1. The base 12 is fixedly installed between the lower surfaces of the two vertical rods 11. The lead screw 2 is rotatably installed between the base 12 and the cover plate 1. The lead screw motor 21 is fixedly installed on the upper surface of the cover plate 1, and the output end of the lead screw motor 21 is fixedly connected to the top end of the lead screw 2. The lead screw slide 22 is sleeved on the outer surface of the lead screw 2, and the lead screw slide 22 is vertically slidably installed between the two vertical rods 11. Two fixed rods 31 are fixedly connected to the front and rear surfaces of the lead screw slide 22, respectively.

[0031] When the lead screw motor 21 rotates, it can drive the lead screw 2 to rotate, thereby driving the lead screw slide 22 to move vertically up and down under the action of the vertical rod 11. Then, through the lifting mechanism 3, it drives the annular spray pipe 4 to move vertically up and down to spray the inner wall of the furnace.

[0032] like Figure 2 As shown, the inner clamping positioning mechanism 7 includes two electric telescopic rods 71. The two electric telescopic rods 71 ​​are symmetrically fixedly installed on the lower surface of the cover plate 1 with the center of the cover plate 1 as the central axis, and rubber contact blocks 72 are fixedly installed on the opposite ends of the two electric telescopic rods 71. When the equipment is in use, the cover plate 1 is fastened to the top of the furnace, and then the two electric telescopic rods 71 ​​are started to extend together. The rubber contact blocks 72 can be used to clamp from the inside of the furnace, thereby fixing the position of the cover plate 1. Since the two electric telescopic rods 71 ​​are symmetrically arranged and move synchronously, after fixing, the center of the inner cavity of the furnace can be in the same position as the center of the annular spray pipe 4, thereby ensuring the uniformity of material spraying.

[0033] Finally, to facilitate the movement of the cover plate 1, handles are symmetrically fixed on the upper surface of the cover plate 1. To ensure the service life of the annular scraper 5, the annular scraper 5 is made of tungsten steel, which has high wear resistance and corrosion resistance.
