Description

Technical Field

[0001] This utility model relates to the field of laminar flow air supply technology, and more specifically to a laminar flow air supply box. Background Technology

[0002] In many industrial and scientific research fields, such as biopharmaceuticals, precision instrument assembly, food processing, and medical operating environments, there are extremely high requirements for airflow stability. Laminar flow air supply technology is one of the important means to achieve these requirements. Its principle is to use a specific air supply device to allow air to enter the working area in a uniform and parallel streamline, avoiding airflow turbulence.

[0003] Existing laminar flow air supply boxes typically adjust airflow through internal structures, such as flow equalization plates and diffusers, to achieve a better laminar flow effect. However, these existing technologies still have some shortcomings in practical applications. For example, some air supply boxes still have room for improvement in airflow organization.

[0004] Therefore, it is necessary to propose a laminar flow air supply box to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the issue that there is still room for improvement in the airflow organization of some air supply boxes.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A laminar flow air supply box includes a box body with an air inlet and an air outlet respectively opened on the upper and lower sides of the box body. A partition is fixedly connected to the inner side of the box body at the lower end of the air inlet, and ventilation holes are opened on the partition. Obtuse-angled plates are symmetrically fixedly connected to the two sides of the box body at the upper end of the air outlet. A support platform is placed in the box body below the two obtuse-angled plates, and an air outlet channel is formed between the two ends of the support platform and the obtuse-angled plates.

[0008] Furthermore, a support leg is fixedly connected to the lower end of the box.

[0009] Furthermore, an insulation layer is fixedly connected to the outer surface of the box.

[0010] Furthermore, right-angled plates are fixedly connected to both ends of the support platform, and an air outlet channel is formed between the right-angled plates and the obtuse-angled plates.

[0011] Furthermore, the end of the partition is fixedly connected to the inside of the box by angle steel.

[0012] Furthermore, the air inlet is symmetrically provided with guide vanes.

[0013] Furthermore, multiple adjusting plates for partially blocking the air outlet channel are slidably connected to the right-angle plate.

[0014] Furthermore, an air outlet channel is formed between the two separated adjustment plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting a partition located below the air inlet and ventilation holes on the partition, can perform preliminary flow equalization and stabilization of the airflow entering the box, effectively reducing airflow turbulence and creating favorable conditions for subsequent laminar flow air supply.

[0017] 2. The obtuse angle plate design of this utility model has an inclination angle that helps guide the airflow to transition smoothly and avoids the airflow from generating eddies or impacts at the air outlet, thereby ensuring that the airflow leaving the box has better laminar flow characteristics.

[0018] 3. In this utility model, the position of the air outlet channel can be adjusted by sliding the baffle through the setting of the adjustment plate. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1 This invention provides a laminar flow air supply box, including a main box 1, which is typically used for uniform spraying, drying, and film formation applications. To facilitate the installation and fixation of the box 1, a support leg 2 is fixedly connected to its lower end. The support leg 2 supports the box 1 at the required height, facilitating equipment connection and maintenance. To reduce energy loss and prevent heat loss due to temperature differences on the outer wall of the box 1, an insulation layer 3 is typically fixedly connected to the outer surface of the box 1. The insulation layer 3 effectively isolates heat exchange between the inside and outside.

[0024] Air inlets 4 and air outlets 10 are respectively provided on the upper and lower sides of the housing 1. Air inlets 4 are the channels through which outside air enters the housing 1, and are usually connected to air supply ducts or pre-filters. Air outlets 10 are the channels through which treated laminar air leaves the housing 1.

[0025] To perform preliminary airflow equalization and stabilization treatment on the air entering the housing 1, a partition 5 is fixedly connected to the inner side of the housing 1 at the lower end of the air inlet 4. For example... Figure 2 As shown, symmetrically arranged arc-shaped guide plates 12 are provided in the air inlet 4. Each guide plate 12 includes a base plate and multiple pairs of arc-shaped guide vanes fixedly connected to the base plate. These guide plates direct airflow into the space above the baffle 5, dispersing and guiding the incoming airflow and reducing turbulence caused by direct impact. To allow air to pass smoothly through the baffle 5 and be further dispersed, evenly distributed ventilation holes 6 are provided on the baffle 5. This can subdivide large airflows into multiple smaller airflows, thereby achieving initial airflow homogenization and laying the foundation for laminar flow. The ends of the baffle 5 are securely fixed to the inside of the housing 1 by angle steel 11, ensuring its structural stability under airflow impact.

[0026] At the lower part of the housing 1, obtuse-angled plates 9 are symmetrically fixedly connected to both sides of the housing 1 above the air outlet 10. These plates serve a guiding function. Their inclination smoothly guides the airflow downwards and prevents abrupt changes in airflow direction near the air outlet 10, which is crucial for maintaining laminar flow and preventing upward movement of the airflow during exhaust. Below the obtuse-angled plates 9, a support platform 7 is placed inside the housing 1 to hold biscuits, flatbreads, soy milk, or other volatile substances produced through spraying or scraping processes. Right-angled plates 8 are fixedly connected to both ends of the support platform 7, forming an exhaust channel together with the obtuse-angled plates 9. During cleaning, the obtuse-angled plates 9 and 8 also prevent air from entering the exhaust channel. This ensures that after passing over the support platform 7, the airflow is smoothly collected and guided to the air outlet 10, contributing to a uniform velocity profile and stable laminar flow characteristics before leaving the housing 1. Finally, the air is exhausted through the air outlet 10.

[0027] Multiple adjusting plates 13 for partially blocking the air outlet channel are slidably connected to the right-angle plate 8. That is, a row of adjusting plates 13 are slidably connected to the right-angle plate 8. When one part of the adjusting plates 13 is slid apart from another part of the adjusting plates 13, an air outlet channel is formed between the two separated adjusting plates 13. The two parts of the adjusting plates 13 that are in contact with each other can block the wind from coming out from the corresponding position.

[0028] The adjusting plate 13 mainly includes an n-shaped plate and an L-shaped plate fixedly connected to one side of the n-shaped plate. The n-shaped plate is slidably connected to the longitudinal surface of the right-angle plate 8, and the end of the L-shaped plate away from the n-shaped plate is attached to the end of the obtuse-angle plate 9.

[0029] In summary, the present invention performs initial flow equalization through partition 5 and ventilation holes 6, and performs final flow guidance and stabilization through the air outlet channel formed by obtuse-angled plate 9 and right-angled plate 8, thereby effectively improving the uniformity and stability of laminar air supply.

The scope of patent protection of this utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of this utility model shall also be included within the scope of protection of this utility model.
