Description

Technical Field

[0001] This utility model belongs to the field of cleanroom air purification, and particularly relates to a cleanroom air intake purification unit. Background Technology

[0002] A cleanroom is a well-sealed space where parameters such as air cleanliness, temperature, humidity, pressure, and noise are controlled as needed. Maintaining a certain level of air cleanliness requires purifying the air entering the cleanroom.

[0003] When purifying the air entering the workshop, multiple filters are used to filter the air. Since these filter materials need to be replaced regularly, these purification units need to adopt a detachable structure design to facilitate the replacement of filter materials. The existing structural design is unreasonable in the process of filter material replacement, making replacement cumbersome and maintenance inefficient. Utility Model Content

[0004] This utility model provides a cleanroom air intake purification unit, which is implemented as follows: A cleanroom air intake purification unit includes: The box assembly includes a main box and a base plate assembled at the bottom of the main box. The main box has two sets of parallel loading frames inside, which divide the interior of the main box into a first cavity, a second cavity and a third cavity. The filter assembly consists of two sets, each assembled in a loading frame. One set of filter assemblies extends from the second cavity to the first cavity, and the other set extends from the second cavity to the third cavity.

[0005] Preferably, the base plate is provided with an assembly port communicating with the second cavity, and the base plate is also provided with a bottom sealing plate to seal the assembly port.

[0006] Preferably, both sets of loading frames are provided with sealing rings on their end faces facing the second cavity, and the filter assembly is sealed to the loading frame through the sealing rings.

[0007] Preferably, the first cavity has an air inlet for introducing airflow on one side, and the third cavity has an air outlet for discharging airflow on one side. The airflow introduced by the air inlet passes sequentially through the first cavity, the first set of filter components, the second cavity, and the second set of filter components to the third cavity. After reaching the third cavity, the airflow is discharged from the air outlet.

[0008] Preferably, the filter assembly includes a high-efficiency filter and a connecting frame connected to the high-efficiency filter. The connecting frame is fixedly assembled on the loading frame by bolts, and the sealing ring fills the gap between the connecting frame and the loading frame.

[0009] Preferably, the inner edge of the connecting frame is provided with an embedding cavity, and when the connecting frame is assembled into the loading frame, the sealing ring extends into the embedding cavity.

[0010] Compared with the prior art, the embodiments of this application have the following main advantages: In the cleanroom air intake purification unit provided by this utility model, the first filter element extends from the second cavity to the first cavity, and the second filter element extends from the second cavity to the third cavity. Both sets of filter components are assembled into the housing assembly through the second cavity. By embedding the entire cleanroom air intake purification unit into the ceiling, the bottom sealing plate at the bottom of the bottom plate of the cleanroom air intake purification unit can be disassembled separately during maintenance. The two sets of filter components can be maintained separately using the second cavity. The optimized structural design allows the secondary filtration system to be maintained through the same set of maintenance windows, reducing the complexity of the equipment structure and improving the maintenance efficiency of the equipment.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This utility model embodiment provides a cleanroom air intake purification unit, such as... Figures 1-5 As shown, the cleanroom air intake purification unit includes: The housing assembly 100 includes a main housing 110 and a base plate 120 assembled at the bottom of the main housing 110. The main housing 110 has two sets of parallel loading frames 140 inside, which divide the interior of the main housing 110 into a first cavity 103, a second cavity 104, and a third cavity 105. An air inlet 102 for introducing airflow is provided on one side of the first cavity 103, and an air outlet 101 for discharging airflow is provided on one side of the third cavity 105. Airflow enters through the air inlet 102 and passes sequentially through the first cavity 103, the second cavity 104, and the third cavity 105. The air inlet 102 and the air outlet 101 are connected to a negative pressure pipe, guiding the airflow with the help of a fan or other equipment. This application does not provide a detailed description of the airflow guiding device for the purification unit. The filter assembly 200 consists of two sets, namely a first filter element and a second filter element, which are assembled on the loading frame 140. The filter assemblies 200 on the loading frame 140 are all fed into the main box 110 from the assembly port 106 provided at the bottom of the second cavity 104. The first filter element extends from the second cavity 104 to the first cavity 103, and the second filter element extends from the second cavity 104 to the third cavity 105; both sets of filter components 200 are assembled into the housing component 100 through the second cavity 104. The optimized design of the structure allows the secondary filtration system to be maintained through the same set of inspection windows, reducing the complexity of the equipment structure and improving the maintenance efficiency of the equipment.

[0020] The outer edge of the main housing 110 can be equipped with a buckle plate assembly that is compatible with the buckle plate. By embedding the cleanroom air intake purification unit into the ceiling, the bottom sealing plate 130 at the bottom of the bottom plate 120 can be disassembled separately during maintenance. The two sets of filter components 200 can be maintained separately using the second cavity 104. It should be noted that the insertion directions of the first filter element and the second filter element are different. Therefore, the filtration directions of the first filter element and the second filter element are opposite. Alternatively, when the first filter element and the second filter element are arranged symmetrically, the filtration directions of the filter elements in the first filter element and the second filter element are the same. In a preferred embodiment of this invention, both sets of loading frames 140 are provided with sealing rings 150 on their end faces facing the second cavity 104. The filter assembly 200 includes a high-efficiency filter 210 and a connecting frame 220 connected to the high-efficiency filter 210. The connecting frame 220 is fixedly assembled on the loading frame 140 by bolts, and the sealing rings 150 fill the gap between the connecting frame 220 and the loading frame 140. In this embodiment, the loading frame 140 needs to be connected to the inner wall of the main housing 110 using a sealing welding technique to prevent airflow gaps between the loading frame 140 and the main housing 110; while the inner edge of the connecting frame 220 is provided with an embedded cavity 201. When the connecting frame 220 is assembled on the loading frame 140, the sealing ring 150 extends into the cavity and fills the entire embedded cavity 201 to achieve a seal. It is also important to note that the high-efficiency filter 210 and the connecting frame 220 in the filter assembly 200 are sealed by welding, and the airflow direction of the high-efficiency filter 210 in the filter assembly 200, which is the first filter and the second filter, needs to be designed to be opposite. In practical applications, the airflow direction needs to be marked on the filter assembly 200 to avoid it being installed backwards during use. In a preferred embodiment of this invention, the base plate 120 has an assembly port 106 that communicates with the second cavity 104; the size of the filter assembly 200 is smaller than the assembly port 106, especially the cross-section of the width and depth of the filter assembly 200 is smaller than the assembly port 106, to ensure that the filter assembly 200 can be installed into the assembly port 106. In this embodiment, a bottom sealing plate 130 is provided at the assembly port 106 for sealing. The fixed connection is still achieved by relying on the sealing ring and bolt fixing method. The structure here can refer to the existing technology. When cleaning and maintaining the filter component 200, attention should also be paid to the maintenance of the sealing ring of the assembly port 106 to avoid damage to the sealing ring caused by disassembly, which could lead to airflow entering.
