Technical Field

[0001] This invention relates to the field of spraying equipment technology, specifically to a spraying device for a nano-aerogel thermal insulation coating with a gradient pore structure. Background Technology

[0002] Gradient porous nano-aerogel thermal insulation coating is a cutting-edge thermal management material. It achieves excellent thermal insulation and heat preservation performance by combining aerogel particles with a polymer substrate material and constructing a gradient porous structure composed of micron- and nano-sized pores inside.

[0003] The patent application with application number CN202121469594.2 mentions "an aerogel spraying device for heat insulation of the outer wall of a grain warehouse". The operation of the nozzle lifting mechanism of the device makes the aerogel sprayed evenly on the outer wall. At the same time, the high pressure formed by the gas storage mechanism is conducive to the spraying of aerogel, avoiding pipeline blockage and improving spraying efficiency and spraying quality.

[0004] However, the aerogel thermal insulation coating spraying equipment currently on the market has a fixed spraying range and a small spraying movement range, resulting in poor spraying efficiency. In addition, it is easy to exceed the spraying range during spraying, which will cause inconvenience to subsequent cleaning and lead to waste of raw materials. Summary of the Invention

[0005] This invention provides a nano-aerogel thermal insulation coating spraying device with a gradient pore structure, which can effectively solve the problems mentioned in the background art, such as fixed spraying range, small spraying movement range, poor spraying efficiency, and easy to exceed the spraying range during spraying, which will cause inconvenience to subsequent cleaning and lead to waste of raw materials.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a nano-aerogel thermal insulation coating spraying device with a gradient pore structure, comprising a spraying machine body, characterized in that: an adjusting spraying component is installed at one end of the spraying machine body, the adjusting spraying component comprising a vertical slide rail; The spraying machine body is equipped with vertical slide rails at one end, and a spraying rail is installed on the slider in the middle of the vertical slide rail. Both ends of the spraying rail are equipped with drive motors, and the output shaft of the drive motor is connected to a drive screw. A spraying rod is threadedly connected to the middle of the drive screw.

[0007] According to the above technical solution, an electric push rod is installed at the end of the spraying rail. One end of the electric push rod is connected to a horizontally moving baffle. A vertical groove is opened on one side of the horizontally moving baffle. A middle plate is welded in the middle of the vertical groove. A guide rod is symmetrically welded through the top surface of the middle plate.

[0008] According to the above technical solution, a vertical baffle is slidably installed inside the vertical groove, the guide rod moves through one side of the vertical baffle, and a return spring is movably sleeved on the guide rod near the middle plate.

[0009] According to the above technical solution, an L-shaped plate is installed at the corresponding guide rod position of the vertical baffle, and the guide rod moves through the L-shaped plate.

[0010] According to the above technical solution, a fixed tube is installed at the position of the electric push rod corresponding to the spraying rail, and a movable rod is slidably installed inside the fixed tube. A horizontally movable baffle is welded to one end of the movable rod.

[0011] According to the above technical solution, the input terminals of the drive motor and the electric push rod are electrically connected to the output terminal of the external controller, and the input terminal of the external controller is electrically connected to the output terminal of the external power supply.

[0012] According to the above technical solution, the horizontally moving baffle is equipped with a cleaning and scraping component, which includes a scraping slide plate; A scraping slide is installed on one side of the horizontally movable baffle. End hook plates are welded to both ends of the scraping slide plate at the corresponding positions of the vertical baffle. A guide rod is welded to the top of the end hook plate.

[0013] According to the above technical solution, a fixed sleeve is welded to one side of the middle part of the scraping slide, a fixed inner rod is welded to the spraying rail corresponding to the fixed sleeve, and a magnetic ring is fixedly sleeved on the fixed inner rod near the fixed sleeve. An air pump is installed on the other side of the middle of the scraping slide. The output end of the air pump is connected to an air delivery pipe, and a jet nozzle is opened on one side of the air delivery pipe.

[0014] According to the above technical solution, the air supply pipe and the scraping slide end face are parallel, and the air pump input end and the external controller output end are electrically connected.

[0015] Compared with the prior art, the advantages of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use; 1. Equipped with an adjustable spraying component, the electric actuator pushes the horizontal moving baffle to move closer to the spraying surface. Under the push of the return spring and the guidance of the guide rod, the vertical baffle slides along the vertical groove to expand the coverage area. When the equipment is started, raw materials are added inside the spraying machine body, and the nano aerogel heat insulation coating is sprayed out through the spraying rod. During this process, the edge of the spray is always blocked by the horizontal moving baffle and the vertical baffle, and moves with the vertical slide rail, always blocking the spraying edge to prevent it from exceeding the spraying range. This avoids material waste and simplifies subsequent cleaning, making it more convenient to use. During the spraying process, the vertical slide rail controls the up and down movement of the spraying rod, while the drive screw is driven by the drive motor to rotate, controlling the left and right movement of the spraying rod. The range of movement is large, and the drive motor drives the spraying, resulting in more uniform spraying and better spraying effect.

[0016] 2. Equipped with a cleaning and scraping component, after spraying, the electric push rod resets, pulling the horizontal moving baffle closer to the scraping slide plate. At this time, the top corner of the vertical baffle slides along the guide bar, pushing the vertical baffle into the vertical groove. The reset spring is compressed until the top of the vertical baffle is engaged inside the end hook plate. During the above process, the material adhering to the side of the vertical baffle is scraped off by the top of the vertical groove. Then, the scraping slide plate is pulled back and forth along the horizontal moving baffle, using the scraping slide plate and end hook plate to scrape off the adhering coating material. During the pulling process, the air pump is activated, and air is ejected through the jet nozzle of the air supply pipe to remove some of the material adhering to the horizontal moving baffle, improving the cleaning effect. Cleaning is simple and convenient, further improving the ease of operation.

[0017] 3. This invention, by setting up a collaborative structure of vertical slide rail, drive screw and spraying rod, makes the spraying range adjustable in two dimensions, thereby significantly expanding the construction coverage of the nano aerogel heat insulation coating and improving the overall spraying efficiency. At the same time, through the linkage shielding mechanism of horizontal moving baffle and vertical baffle, dynamic sealing control of the spraying edge is achieved, effectively avoiding over-spraying of the coating, reducing material waste and reducing the difficulty of subsequent cleaning.

[0018] In addition, through the coordinated design of the cleaning and scraping components, guide rods and end hook plates, this device can mechanically scrape off residual coatings and perform structural repositioning after spraying. Combined with the air pump jet-assisted cleaning method, it further improves the cleaning effect, ensures the stability and cleanliness of the equipment for repeated use, and the magnetic positioning structure also improves the convenience of assembling and disassembling the cleaning components.

[0019] In summary, this invention improves spray uniformity and construction efficiency while achieving synergistic optimization of precise control of spray range and efficient cleaning of residues. The overall structure is scientific and reasonable, and it has good engineering application value and promotion significance. Attached Figure Description

One end of the electric actuator 206 is connected to... A horizontally movable baffle 207 is provided, and a vertical groove 208 is provided on one side of the horizontally movable baffle 207. A middle plate 209 is welded to the middle of the vertical groove 208. A guide rod 210 is symmetrically welded through the top surface of the middle plate 209. A vertical baffle 211 is slidably installed inside the vertical groove 208. The guide rod 210 moves through one side of the vertical baffle 211. An L-shaped plate is installed on the vertical baffle 211 corresponding to the guide rod 210. The guide rod 210 moves through the L-shaped plate, making the movement of the vertical baffle 211 more stable. A return spring 212 is movably sleeved on the guide rod 210 near the middle plate 209.

[0024] The horizontally moving baffle 207 is equipped with a cleaning and scraping assembly 3, which includes a scraping slide plate 301, an end hook plate 302, a guide bar 303, a fixing sleeve 304, a fixing inner rod 305, a magnetic ring 306, an air pump 307, an air delivery pipe 308, and an air jet orifice 309. A scraping slide plate 301 is installed on one side of the horizontal moving baffle 207. At both ends of the scraping slide plate 301, corresponding to the vertical baffle 211, end hook plates 302 are welded. At the top of the end hook plate 302, a guide diagonal rod 303 is welded.

An air jet slit 309 is opened on one side of the air supply pipe 308.

[0025] The working principle and usage process of this invention are as follows: Before spraying, the spraying machine body 1 is moved to the spraying position, and the spraying distance is controlled as needed. Then, the electric push rod 206 is started. The electric push rod 206 pushes the horizontal moving baffle 207 to move closer to the spraying surface. Under the push of the return spring 212 and the guidance of the guide rod 210, the vertical baffle 211 slides along the vertical groove 208 to expand the shielding range. The equipment is started, and raw materials are added inside the spraying machine body 1. The nano aerogel heat insulation coating is sprayed out through the spraying rod 205. During this process, the edge of the spray is always blocked by the horizontal moving baffle 207 and the vertical baffle 211, and moves with the vertical slide rail 201, always shielding the spraying edge to prevent it from exceeding the spraying range. This avoids waste of raw materials and simplifies subsequent cleaning, making it more convenient to use. During the spraying process, the vertical slide rail 201 controls the spraying rod 205 to move up and down, while the drive screw 204 is driven by the drive motor 203 to rotate, controlling the spraying rod 205 to move left and right. The range of movement is large, and the drive motor 203 drives the spraying, making the spraying more uniform and the spraying effect better. During spraying, the fixing sleeve 304 of the scraping slide plate 301 is fitted onto the fixing inner rod 305, and the magnetic ring 306 temporarily fixes the fixing sleeve 304. After spraying is completed, the electric push rod 206 resets, pulling the horizontal moving baffle 207 closer to the scraping slide plate 301. At this time, the top corner of the vertical baffle 211 slides along the guide rod 303, pushing the vertical baffle 211 into the vertical groove 208. The return spring 212 is compressed until the top of the vertical baffle 211 is engaged inside the end hook plate 302. In the above process, the material adhering to the side of the vertical baffle 211 is scraped off by the top of the vertical groove 208. Then, the scraping slide 301 is pulled back and forth along the horizontal moving baffle 207. The scraping slide 301 and the end hook plate 302 are used to scrape off the adhering coating material. During the pulling process, the air pump 307 is started, and air is sprayed out through the jet hole 309 of the air supply pipe 308 to remove some of the material adhering to the horizontal moving baffle 207, thereby improving the cleaning effect, making cleaning simple and convenient, and further improving the ease of operation.
