Description

Technical Field

[0001] The utility model relates to the technical field of painting workshops, in particular to a vehicle painting dynamic pressure chamber with a diffuser hood and a painting workshop. Background Art

[0002] In the design of the air supply system of the dynamic pressure chamber in the painting workshop of a painting booth, the air supply opening where the industrial air conditioning air duct is docked with the dynamic pressure chamber of the painting booth is usually equipped with a diffuser hood. Its main purpose is to better evenly disperse the air flow, so as to ensure the uniform distribution of the air flow in the painting booth and improve the painting quality.

[0003] However, the existing diffuser hood designs have many deficiencies. First of all, the traditional diffuser hood is usually composed of a single-sided perforated plate, with suspension rods for fixing around it. Although this structure can play a role in dispersing the air flow to a certain extent, its dispersion effect is often not ideal. Due to the design of the single-sided perforated plate, the effective cross-sectional area for dispersing the air flow is relatively limited, making it difficult to achieve the full diffusion and uniform distribution of the air flow.

[0004] Secondly, there are also obvious defects in the installation and maintenance of the existing diffuser hood. Due to the use of fixed suspension rods for installation, this design makes the diffuser hood not easy to disassemble. When cleaning, maintenance or replacement is required, operators often need to spend a lot of time and effort, and may even need to stop the operation of the entire painting booth, which will undoubtedly reduce production efficiency and increase maintenance costs.

[0005] In addition, the single perforated plate design also limits the adjustability of air flow dispersion. During different painting processes or the painting of workpieces of different specifications, it may be necessary to adjust the dispersion mode and intensity of the air flow. However, the existing diffuser hoods are difficult to meet this flexible adjustment requirement and cannot be optimized for different painting needs.

[0006] Finally, the structure of the traditional diffuser hood is relatively simple and difficult to cope with complex air flow distribution requirements. During the painting of large or complex-shaped workpieces, more refined and diversified air flow control may be required, while the single perforated plate design is difficult to meet these advanced requirements.

[0007] In summary, the existing diffuser hoods at the air supply openings of the dynamic pressure chambers in the painting booths of painting workshops have significant deficiencies in terms of air flow dispersion effect, installation and maintenance convenience, adjustability, and adaptability to complex painting requirements. There is an urgent need for technological innovation and improvement to meet the higher requirements of modern painting processes for precise air flow control. Content of the Utility Model

[0008] The technical problem to be solved by the present utility model is to provide a dynamic pressure chamber for vehicle painting with a diffuser cover aiming at the defects in the prior art, which can evenly disperse the air flow in the air conditioning air supply duct into the dynamic pressure chamber of the painting chamber.

[0009] The technical solution adopted by the present utility model to solve its technical problems is as follows: The present utility model provides a dynamic pressure chamber for vehicle painting with a diffuser cover, including an air supply duct and a dynamic pressure chamber. The diffuser cover is arranged in the dynamic pressure chamber, and the air outlet of the air supply duct is located inside the diffuser cover. The diffuser cover and the dynamic pressure chamber enclose a diffuser chamber, which includes an upper chamber and a lower chamber. The cross-sectional shape and longitudinal-sectional shape of the upper chamber are both rectangular. The cross-sectional shape of the lower chamber is an isosceles trapezoid and its longitudinal-sectional shape is rectangular. The air supply duct is communicated with the upper chamber, and the upper chamber is communicated with the lower chamber. The diffuser cover is provided with diversion holes for realizing the communication between the dynamic pressure chamber and the diffuser chamber.

[0010] In a preferred embodiment of the present utility model, the diffuser cover includes a bottom plate, and each of the two long sides of the bottom plate is connected with an inclined plate. The two inclined plates are arranged in mirror symmetry. Each inclined plate is connected with a side plate above it, and the side plate is perpendicular to the bottom plate. Each of the two wide sides of the bottom plate is connected with an end plate. Each end plate includes a hypotenuse corresponding to the wide side of the inclined plate and a straight side corresponding to the wide side of the side plate. A plurality of diversion holes arranged in an array are provided on the bottom plate, the inclined plates, the side plates and the end plates. Flanges are provided at the tops of the side plates and the end plates, and mounting holes for fixedly connecting with the dynamic pressure chamber are provided on the flanges. There is a hole on at least one inclined plate and a maintenance plate which is connected to the inclined plate and can be opened and closed. The maintenance plate corresponds to the arrangement position of the hole, and a plurality of diversion holes arranged in an array are provided on the maintenance plate.

[0011] In a preferred embodiment of the present utility model, the hole provided on the inclined plate is a rectangular hole.

[0012] In a preferred embodiment of the present utility model, a hinge is connected to the inclined plate, and the hinge is connected with the maintenance plate.

[0013] In a preferred embodiment of the present utility model, a movable bolt is connected to the inclined plate, and the bolt end of the movable bolt is arranged on the maintenance plate.

[0014] In a preferred embodiment of the present utility model, the shape of the end plate includes an isosceles trapezoid and a rectangle, and the long side of the isosceles trapezoid corresponds to the long side of the rectangle.

[0015] In a preferred embodiment of the present utility model, the bottom plate is rectangular.

[0016] In a preferred embodiment of the present utility model, the inclined plate is rectangular.

[0017] In a preferred embodiment of the present utility model, the side plate is rectangular.

[0018] The present utility model also discloses a painting workshop including a vehicle painting dynamic pressure chamber with a diffuser hood.

[0019] The beneficial effects of the present utility model are as follows: The vehicle painting dynamic pressure chamber with a diffuser hood provided by the present utility model not only solves the problems of poor air flow dispersion effect and difficult maintenance of traditional diffuser devices, but also significantly improves the uniformity and efficiency of air flow dispersion through innovative structural design. It has the advantages of reasonable structure, convenient use, easy maintenance, and strong adaptability. The application of this device will significantly improve the working efficiency and spraying quality of the vehicle painting chamber, providing an advanced, economical and practical technical solution for the painting process in the automotive manufacturing industry, and is expected to promote the technological progress and production efficiency improvement of the entire industry;

[0020] Specifically, first of all, the device innovatively designs a diffuser chamber structure composed of an upper chamber and a lower chamber. The upper chamber is designed as a rectangle, while the lower chamber has an isosceles trapezoidal cross-section. This unique combination not only increases the effective space for air flow dispersion, but also better guides the uniform distribution of air flow. Especially the design of the isosceles trapezoidal lower chamber can effectively reduce air flow dead zones and ensure the consistency of air flow distribution in the dynamic pressure chamber.

[0021] Secondly, the multi-faceted structure of the diffuser hood (including the bottom plate, inclined plate, side plate and end plate) greatly increases the effective area of air flow dispersion. A plurality of diversion holes arranged in an array are provided on each surface. This all-round porous design significantly improves the uniformity and efficiency of air flow dispersion, ensuring a more ideal air flow distribution in the painting chamber.

[0022] Furthermore, the maintenance design of the device greatly improves the maintainability of the equipment. By setting an openable and closable maintenance plate on the inclined plate and cooperating with the use of hinges and movable bolts, the maintenance and cleaning work become extremely convenient. This not only reduces the maintenance cost, but also reduces the downtime caused by maintenance and improves the overall production efficiency.

[0023] In addition, the geometric shape design of each component of the diffuser hood (bottom plate, inclined plate, side plate, end plate) is simple and reasonable, mostly using rectangles or isosceles trapezoids. This not only facilitates processing and manufacturing, but also ensures the structural stability and the uniformity of air flow distribution. The flanging design and the setting of installation holes greatly simplify the installation process and improve the installation efficiency.

[0024] Finally, the design of this device fully considers the actual usage requirements and flexibility. Through the adjustable maintenance panel, operators can adjust or clean the internal structure as needed. This flexibility enables the device to adapt to different spray painting process requirements, improving the applicability and practical value of the equipment. Brief Description of the Drawings

[0030] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not used to limit the present utility model.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of the present utility model.

[0032] Embodiment 1

[0033] As Figures 1-4 shown, the present utility model provides a vehicle spray painting dynamic pressure chamber with a diffuser hood, mainly composed of an air supply pipe 1 and a dynamic pressure chamber 2. A diffuser hood 3 is arranged in the dynamic pressure chamber 2, and the air outlet of the air supply pipe 1 is located inside the diffuser hood 3. The diffuser hood 3 and the dynamic pressure chamber 2 ingeniously enclose a diffuser chamber, which is further divided into an upper chamber and a lower chamber. The upper chamber is designed as a rectangle, and its cross-section and longitudinal section are both rectangular. The lower chamber has a unique isosceles trapezoidal cross-section, and its longitudinal section remains rectangular. This design enables the air supply pipe 1 to be directly connected to the upper chamber, and at the same time, the upper chamber is connected to the lower chamber, forming a complete air flow channel.

[0034] The structure of the air diffuser 3 is exquisitely designed and practical. It mainly consists of a bottom plate 3.1, inclined plates 3.2, side plates 3.3 and end plates 3.4. The bottom plate 3.1 is designed as a rectangle and serves as the foundation of the entire structure. The two inclined plates 3.2 are arranged in mirror symmetry and are respectively connected to the two long sides of the bottom plate 3.1. Above each inclined plate 3.2, a side plate 3.3 is connected, and the side plate is perpendicular to the bottom plate 3.1. The end plates 3.4 are connected to the two wide sides of the bottom plate 3.1, and their shapes include hypotenuses corresponding to the wide sides of the inclined plates 3.2 and straight sides corresponding to the wide sides of the side plates 3.3. In order to effectively connect the dynamic pressure chamber 2 and the air diffuser chamber, a plurality of flow guiding holes 3.5 arranged in an array are provided on the bottom plate 3.1, inclined plates 3.2, side plates 3.3 and end plates 3.4. In addition, flanges 3.6 are designed on the tops of the side plates 3.3 and end plates 3.4, and mounting holes 3.7 are also provided on the flanges for fixed connection with the dynamic pressure chamber 2.

[0035] Embodiment 2

[0036] On the basis of Embodiment 1, this embodiment further optimizes the structure and function of the air diffuser. For the convenience of equipment maintenance and cleaning, a rectangular hole is ingeniously provided on at least one inclined plate 3.2, and a detachable inspection plate 4 is equipped. The position of this inspection plate 4 corresponds to the rectangular hole, and at the same time, a plurality of flow guiding holes 3.5 arranged in an array are also provided on its surface to ensure the continuity of air flow distribution. In order to realize the flexible opening and closing of the inspection plate, hinges 5 are installed on the inclined plate 3.2 to connect the inspection plate 4 to the inclined plate. At the same time, in order to ensure the stability of the inspection plate in the closed state, a movable bolt 6 is also designed on the inclined plate 3.2, and its bolt end exactly corresponds to the jack on the inspection plate 4.

[0037] In terms of material selection, all components are made of galvanized steel plates with a thickness of 1.5 mm, which not only ensures the durability of the structure but also improves its corrosion resistance. The entire air diffuser device 4.2 is firmly installed on the top plate 4.3 of the dynamic pressure chamber through M8 standard bolt and nut fasteners 5.1, ensuring the stability during use.

[0038] Embodiment 3

[0039] In response to the special requirements of large vehicle painting booths, this embodiment further optimizes and adjusts on the basis of the first two embodiments. First of all, the overall size of the air diffuser 3 has been significantly increased. The length of the bottom plate 3.1 is extended to 3000 mm and the width is increased to 1500 mm to meet the painting requirements of large vehicles. Secondly, an intermediate chamber is ingeniously added between the original upper chamber and lower chamber. This newly added intermediate chamber has a rectangular cross-section design with a height of 300 mm. This three-layer design not only optimizes the air flow distribution but also is particularly suitable for the painting requirements of large vehicles.

[0040] In order to further improve the uniformity of air flow distribution, this embodiment has made an innovative design for the air guiding holes 3.5. The air guiding holes on the bottom plate 3.1, the inclined plate 3.2 and the side plate 3.3 adopt a design with a gradually changing diameter. In the area close to the air supply duct 1, the diameter of the air guiding holes is relatively small, about 15 mm, and then gradually increases towards the distal end, reaching a maximum of 30 mm. This ingenious design effectively balances the air flow pressure and ensures a high degree of uniformity in the air flow distribution in the painting chamber of large vehicles.

[0041] Considering the special requirements of the painting chamber for large vehicles, this embodiment has also been upgraded in terms of material selection. All components are made of 2-mm-thick stainless steel plates, which not only improves the structural strength but also further enhances the corrosion resistance. At the same time, in order to facilitate the overall maintenance and cleaning of large equipment, an inspection plate 4 is provided on each of the two inclined plates 3.2, greatly improving the convenience of maintenance.

[0042] Embodiment 4

[0043] This embodiment focuses on the design of an intelligent painting chamber and introduces a number of intelligent functions on the basis of the foregoing embodiments. First, a plurality of air flow sensors are installed on the diffuser hood 3. These sensors are connected to an external control system and can monitor the air flow state in the diffuser chamber in real time and automatically adjust the air supply volume and speed of the air supply duct 1 according to the actual situation. Second, some of the air guiding holes 3.5 on the bottom plate 3.1 and the inclined plate 3.2 are designed to have an adjustable opening structure. These adjustable air guiding holes are controlled by an electric actuator and can automatically adjust the opening according to different vehicle models and painting requirements to achieve more precise air flow control.

[0044] In order to improve the flexibility and maintainability of the system, the diffuser hood 3 adopts a modular design. The size of each module is 500 mm x 500 mm and they are connected by snap connections, and can be quickly assembled or replaced according to the requirements of different painting chambers. In addition, the surfaces of all components have been subjected to special anti-static treatment, effectively reducing dust adsorption and improving the painting quality.

[0045] In terms of data collection and analysis, in this embodiment, a plurality of temperature and humidity sensors are installed on the air diffuser hood 3. The spray painting environment data collected by these sensors is transmitted to the central control system in real time through Internet of Things technology for optimizing spray painting parameters and predicting maintenance requirements. Finally, by installing a micro camera and combining artificial intelligence image analysis technology, remote monitoring of the working state of the air diffuser hood 3 is achieved, and potential problems can be detected and solved in a timely manner. The design of the air diffuser hood of the present utility model not only improves the uniformity and efficiency of air flow dispersion, but also greatly simplifies the installation and maintenance process. The design of the inspection plate makes internal cleaning and adjustment extremely convenient, while the all-round porous design ensures a more ideal air flow distribution in the spray painting room. This innovative structural design provides an efficient, economical and practical technical solution for the vehicle spray painting process, and is expected to significantly improve the painting quality and production efficiency.
