Description

Technical Field

[0001] This utility model belongs to the field of spraying technology, and in particular to a portable polyurea spraying device for industrial energy-saving furnaces. Background Technology

[0002] Polyurea is a high-performance elastomeric coating material with excellent physical properties and chemical stability. When applied to the surface of industrial energy-saving furnaces, it can impart properties such as high-temperature resistance, wear resistance, and chemical corrosion resistance to the furnace body.

[0003] However, many traditional industrial energy-saving furnaces suffer from poor surface treatment, and the protective layer gradually fails over time. In such cases, polyurea spraying technology can significantly improve their protective performance. However, since existing industrial energy-saving furnaces are usually surrounded by related equipment, the space available for polyurea spraying equipment is very limited. Therefore, a portable polyurea spraying device is needed to meet the operational requirements within such limited space. Utility Model Content

[0004] Purpose of the utility model: To provide a portable polyurea spraying device for industrial energy-saving furnaces, so as to solve the above-mentioned problems existing in the prior art.

[0005] Technical solution: A portable polyurea spraying device for industrial energy-saving furnaces includes a frame, a dual-station moving wheel system, an air compressor assembly, and a material box. The air compressor assembly is mounted on the frame, and its output end is connected to the material box. The material box is hinged to the frame, and its output end is connected to the sprayed part through a hose. The dual-station moving wheel system is mounted on the frame and is used to move the frame in an upright or horizontal position.

[0006] Furthermore, the dual-station moving wheel system includes a horizontal wheel set, a vertical wheel set, and a dual-station wheel set distributed in a right-angled triangle on the frame, with the dual-station wheel set located at the right-angle end.

[0007] Furthermore, the dual-station wheel set includes casters and brakes, with the casters mounted on the frame and the brakes mounted on the casters.

[0008] Furthermore, the hose between the sprayed part and the material box is wound around a take-up reel, which is hinged to the frame.

[0009] Furthermore, the frame is provided with a snap-fit ​​structure, and the spraying parts are mounted on the snap-fit ​​structure.

[0010] Furthermore, the material box is equipped with a counterweight to maintain the material box outlet vertically downward in the upright or horizontal state of the frame.

[0019] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0020] like Figures 1-4 As shown, a portable polyurea spraying device for an industrial energy-saving furnace includes a frame 2, a dual-station moving wheel system, an air compressor assembly 6, and a material box 7. The air compressor assembly 6 is mounted on the frame 2, and its output end is connected to the material box 7. The material box 7 is hinged to the frame 2, and its output end is connected to the sprayed part 8 through a hose. The dual-station moving wheel system is mounted on the frame 2 for moving the frame 2 in an upright or horizontal position.

[0021] The portable polyurea spraying device 1 provided by this utility model has flexible mobility and can adapt to the operational needs of different positions. It is equipped with a dual-station moving wheel system, which allows the frame 2 to move in an upright or horizontal position, thereby enabling convenient position adjustment in confined spaces and adapting to various working environments. The material bin 7 of the device is designed to be hinged to the frame 2, ensuring that the output port of the material bin 7 remains vertically downward regardless of whether it is in an upright or horizontal position. This ensures smooth flow of the spraying material, improving spraying efficiency and quality.

[0022] In summary, the portable polyurea spraying device 1 provided by this utility model effectively solves the inconvenience of traditional spraying equipment when operating in confined spaces, improves the flexibility and efficiency of spraying work, and also improves the working conditions of operators.

[0023] like Figure 2 and Figure 3 As shown, the dual-station moving wheel system includes a horizontal wheel set 4, a vertical wheel set 5, and a dual-station wheel set 3 arranged in a right-angled triangle on the frame 2. The dual-station wheel set 3 is located at the right-angle end. The dual-station wheel set 3 includes casters and brakes. The casters are mounted on the frame 2, and the brakes are mounted on the casters.

[0024] The advantage of the right-angled triangle layout of the dual-station mobile wheel system lies in its improved stability and flexibility. Specifically, the right-angled triangle layout allows for easier directional changes. In particular, the omnidirectional wheels included in the dual-station wheel set can rotate freely in all directions, and with the added function of the brakes, the operator can easily control the movement of the equipment, whether forward, backward, or lateral. Furthermore, this design considers that the frame can be switched between upright and horizontal positions, meaning that the equipment can be placed stably whether upright or flat, and movement can be achieved by adjusting different wheel sets. This further enhances the versatility and practicality of the portable polyurea spraying device, making it more suitable for applications in various scenarios.

[0025] The flexible hose between the sprayed part 8 and the material bin 7 is wound around a take-up reel 9, which is hinged to the frame 2. The take-up reel 9 is designed to facilitate hose management and use. Specifically, when the hose is not fully extended, it can be neatly wound around the take-up reel 9, preventing it from dragging haphazardly on the ground and causing safety hazards or hindering operator movement. Furthermore, the take-up reel 9 itself is hinged to the frame 2, meaning its position can be adjusted as needed to prevent the hose from colliding with other objects during operation.

[0026] Both the dual-station moving wheel system and the take-up tray 9 can be mounted inside the frame 2, providing better protection and reducing the chance of collisions with external obstacles during movement. This design is particularly important for portable polyurea spraying equipment 1 operating in narrow or congested environments. For example, in an industrial site filled with pipes, supports, and other fixed equipment, the operator may need to frequently adjust the position of the spraying equipment to cover the entire surface of the industrial energy-saving furnace 0. In this case, if the moving wheel system and take-up tray of the spraying equipment are designed inside the frame, unnecessary contact with these fixed devices during movement can be effectively prevented, reducing the risk of damage. Simultaneously, this allows the operator to focus more on the spraying work without worrying about equipment parts accidentally colliding with surrounding facilities. This design makes the portable polyurea spraying equipment 1 not only safer and more reliable but also improves work efficiency.

[0027] The frame 2 is equipped with a snap-fit ​​structure on which the paint sprayer 8 is mounted. The snap-fit ​​structure on the frame 2 provides a quick way to connect and release the paint sprayer 8. The snap-fit ​​structure is a slot with a spring-loaded locking mechanism, and the paint sprayer 8 has a corresponding protrusion or hook, allowing the paint sprayer to be quickly installed onto the frame and securely fixed. The snap-fit ​​structure not only makes the installation and removal of the paint sprayer 8 simple and quick, but also provides reliable fixation during operation, avoiding safety hazards caused by accidental loosening. Furthermore, because the snap-fit ​​structure is typically compact, it also helps reduce shaking of the paint sprayer during transportation or movement, thus protecting the equipment from damage.

[0028] The material box 7 is equipped with a counterweight to keep the output port of the material box 7 vertically downward in the upright or horizontal state of the frame 2. The frame 2 is equipped with a limit pin, which cooperates with the material box 7 to limit the hinged posture of the material box 7.

[0029] The main purpose of the counterweight on the material bin 7 is to ensure that the output port of the material bin 7 always remains vertically downward, regardless of whether the frame 2 is in an upright or horizontal position. This is achieved by adding appropriate weight to the material bin, allowing gravity to help the bin hang naturally, thus ensuring the smooth flow of the coating material. The counterweight design takes into account the changes in the center of gravity of the material bin under different postures, enabling the material bin 7 to automatically adjust to the optimal discharge angle. The limiting pin installed on the frame 2 cooperates with the material bin 7 to limit the hinged posture of the material bin 7. When the frame 2 changes posture, the material bin 7 can rotate accordingly, but this rotation is limited. The function of the limiting pin is to prevent the material bin from rotating further when it reaches a certain angle, thus ensuring that the output port of the material bin 7 is always in the correct direction. This avoids the situation where the coating material cannot flow out normally due to excessive rotation of the material bin 7, ensuring the continuity and efficiency of the spraying operation.

[0030] like Figure 4 As shown, the spraying component 8 includes a bending rod 81, a shut-off valve 82, a nozzle 83, a handle 84, and a guide wheel 85. One end of the bending rod 81 is connected to a hose connected to the material box 7, and the other end is equipped with the nozzle 83. The guide wheel 85 is installed at the bend of the bending rod 81. The shut-off valve 82 is installed at the end of the bending rod 81 away from the nozzle 83. The handle 84 is installed on the bending rod 81 and is located between the shut-off valve 82 and the guide wheel 85.

[0031] The design of spray coating part 8 makes it ideal for spraying in small crevices or hard-to-reach areas within industrial energy-saving furnaces. The following is a detailed description of the usage process for spray coating part 8:

[0032] First, ensure that the air compressor assembly 6 is started and providing sufficient air pressure. Then, connect the spray nozzle 8 to the material tank 7 via a hose. The operator must check that the shut-off valve 82 is closed to prevent paint leakage during the preparation phase.

[0033] Then, the operator grasps the handle 84, which is the operating handle part of the spraying part 8. The position of the handle 84 is designed precisely between the shut-off valve 82 and the guide wheel 85, so that the operator can control the shut-off valve 82 with one hand while the other hand can move the spraying part 8 freely.

[0034] Next, depending on the area to be sprayed, the operator can bend the bending rod 81 so that the nozzle 83 can reach into the small gaps or corners of the industrial energy-saving furnace 0. The guide wheel 85 is installed at the bend of the bending rod 81, which can help the sprayed part 8 move smoothly along the furnace wall or other obstacles, reduce frictional resistance, and make the operation smoother.

[0035] When the nozzle 83 is accurately positioned at the location to be sprayed, the operator opens the shut-off valve 82, and the paint is delivered from the hopper 7 to the nozzle 83 through the hose, and then evenly sprayed onto the target surface under the action of compressed air.

[0036] In this way, the sprayed part 8 can not only effectively deal with the small gaps and hard-to-reach corners on the industrial energy-saving furnace 0, but also ensure the accuracy and efficiency of the spraying operation. This design allows operators to flexibly adapt to different spraying needs, improving the applicability and operational efficiency of the portable polyurea spraying device.

However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
