Detailed Implementation

[0024] The following description, in conjunction with embodiments, provides a clear and complete explanation of the technical solution of this utility model, enabling those skilled in the art to fully understand it. Obviously, the described embodiments are merely some preferred embodiments of this utility model, and not all embodiments. Any equivalent modifications or substitutions made by those skilled in the art to the following embodiments without creative effort are within the protection scope of this utility model.

[0025] Please see Figures 1 to 5 As shown, this embodiment of the invention provides a super-clean cooled glove box, specifically including a glove box body 1, a super-clean component 2 connected to the top of the glove box body 1, an electrical control box 4 installed at the lower part or side of the glove box body 1 (in this embodiment, the electrical control box 4 is installed at the lower part of the glove box body 1), and a cooling system 3 connected to the outside of the glove box body 1. In this embodiment, by using the super-clean component 2 and the cooling system 3 connected to the glove box body 1, a glove box with ISO 4 cleanliness is provided to the customer, and the ambient temperature can be controlled at any constant temperature within the range of 0~25℃, with a temperature control accuracy of ±1℃.

[0026] Please see Figures 1 to 4As shown, the super-clean assembly 2 includes a super-clean housing 2.1 fixedly installed on the top of the glove box body 1. An FFU super-clean filter assembly 2.2, communicating with the glove box body 1, is installed inside the super-clean housing 2.1. A porous plate assembly 2.4 is fixedly installed at the bottom inside the glove box body 1. The porous plate assembly 2.4 and the FFU super-clean filter assembly 2.2 are connected via an FFU air duct 2.3. The FFU super-clean filter assembly includes a primary filter and a secondary filter. The primary filter has a diameter of 0.3 μm, and the secondary filter has a diameter of 0.12 μm.

[0027] Please see Figure 4 As shown, the perforated plate assembly 2.4 includes a first perforated plate 2.4.1, a second perforated plate 2.4.2, and a third perforated plate 2.4.3 connected in series. These three plates are fixedly installed to the bottom of the glove box body 1. A supporting angle steel assembly 2.5 is provided on the inner bottom wall of the glove box body 1, and the first, second, and third perforated plates 2.4.1, 2.4.2, and 2.4.3 are fixedly installed on the supporting angle steel assembly 2.5. The super-clean assembly 2, through the perforated plate assembly 2.4, divides the interior of the glove box body 1 into a double-layer structure, immersing the process equipment and operations in a super-clean atmosphere, ensuring thorough purification of the atmosphere within the box without any dead zones.

[0028] In this embodiment, the FFU ultra-clean filter assembly 2.2 is equipped with a two-stage filter. The first-stage filter has a diameter of 0.3μm and can filter particles larger than 0.3μm; the second-stage filter has a diameter of 0.12μm and can filter fine particles larger than 0.12μm, dust, and various pathogens, thereby achieving ISO Class 4 cleanliness for the atmosphere of the glove box body 1. The perforated plate assembly 2.4 is installed on the supporting angle steel assembly 2.5 at the bottom of the box 1.1. The product manufacturing equipment or experimental equipment built into the box 1.1 can be installed on the perforated plate assembly 2.4, so that the product manufacturing equipment or experimental equipment is completely immersed in a clean and dust-free atmosphere.

[0029] In this embodiment, the glove box body 1 and the super-clean assembly 2 form a complete circuit for water removal, oxygen removal, removal of organic gases, and multi-stage dust removal. The super-clean cover 2.1, the box body 1.1, and the perforated plate assembly 2.4 installed at the bottom of the box body 1.1 are interconnected to form a three-layer chamber, which is connected by an FFU air duct 2.3 and operated by the FFU super-clean filter assembly 2.2 to achieve circulating filtration of the atmosphere inside the chamber (see...). Figure 2 and Figure 3 (The direction of the loop is indicated by the middle arrow). The extra-large cross-section design of the FFU air duct 2.3 draws the air from the bottom chamber of the porous plate assembly 2.4 inside the housing 1.1 into the ultra-clean enclosure 2.1, and then filters it through the FFU ultra-clean filter assembly 2.2 before blowing it into the inner cavity of the housing to achieve full filtration of the air in the housing.

[0030] Please see Figures 1 to 4 As shown, the glove box body 1 includes a box body 1.1. A purification column 1.4 is fixedly installed at the bottom of the box body 1.1. An air inlet pipe 1.5 is connected between the FFU ultra-clean filter assembly 2.2 and the purification column 1.4, and an air outlet pipe 1.3 is connected between the box body 1.1 and the purification column 1.4. An air inlet filter element 1.6 is provided at the end of the air inlet pipe 1.5, and an air outlet filter element 1.2 is provided at the end of the air outlet pipe 1.3. In this embodiment, the specifications of the air inlet filter element 1.6 and the air outlet filter element 1.2 are 0.3μm. High-purity inert gas is filled into the box body and circulated to filter out active substances, mainly for the removal and filtration of O2, H2O, organic gases, and particles >0.3μm. The atmosphere inside chamber 1.1 flows through the glove box outlet filter element 1.2 and outlet pipe 1.3, passes through the purification column 2, and then through the inlet pipe 1.5 and inlet filter element 1.6 before being blown into the ultra-clean enclosure 2.1. This process removes O2, H2O, and organic gases from the chamber atmosphere. The ultra-clean filter assembly 2.2 then performs preliminary filtration and adsorption of particles >0.3μm in the atmosphere. The ultra-clean enclosure 2.1 is installed on the top of the glove box body 1 and is connected to the inner cavity of chamber 1.1 via the ultra-clean filter assembly 2.2. Both the ultra-clean enclosure 2.1 and the back of chamber 1.1 have square holes, which are connected through the FFU air duct 2.3 assembled on the back. The operation of the ultra-clean filter assembly 2.2 achieves circulating filtration of the atmosphere inside the chamber. After filtration by the primary 0.3μm filter and the secondary 0.12μm filter configured in the ultra-clean filter assembly 2.2, the air achieves ISO Class 4 cleanliness. The water-cooled pipe assembly 3.1 is installed in series inside the FFU air duct 2.3 (the four water-cooled pipe assemblies in the water-cooled pipe assembly 3.1 are integrated in series in the FFU air duct 2.3), and is connected to the chiller 3.5. The operation of the chiller 3.5 is controlled by the electrical control box 4 through the temperature sensor 3.2 to monitor and provide feedback, so as to achieve temperature control of the atmosphere inside the chamber.

[0031] Please see Figure 5As shown, the cooling system 3 specifically includes a water-cooled pipe assembly 3.1, which is installed in series inside the FFU duct 2.3. The water-cooled pipe assembly 3.1 is connected to an inlet pipe 3.3 and a return pipe 3.4, both of which are connected to an external chiller 3.5. A temperature sensor 3.2 is installed on the FFU duct 2.3 and is electrically connected to the electrical control box 4. The water-cooled pipe assembly 3.1, consisting of four sets of cooling water pipes integrated in series within the FFU duct 2.3, can efficiently reduce the temperature of the chamber atmosphere. The external chiller 3.5 reduces the impact of cooling system vibration on the internal product manufacturing process or experimental activities, and effectively controls the overall height of the glove box to suit customer locations with height restrictions. The temperature sensor 3.2 is preferably a PT100 temperature sensor. The PT100 temperature sensor 3.2 is installed in the cooling system 3 and connected to the electrical control box 4. The electrical control system controls the operation of the chiller 3.5 based on the feedback temperature information to control the temperature of the chamber atmosphere, maintaining it at a constant temperature within the range of 0~25℃ with a temperature control accuracy of ±1℃. In this embodiment, the cooling system 3 cools the heat generated by the FFU ultra-clean filter group 2.2 and the heat generated during product manufacturing or experimental activities, thus maintaining the temperature of the chamber atmosphere at a constant level.
