Description

TECHNICAL FIELD

[0002] The high-efficiency air supply port of a clean room is the core terminal equipment of the air purification system of the clean room, which is used to send the clean air purified by the high-efficiency filter into the working area of the clean room in the form of uniform and stable airflow, so as to ensure that the air sent into the room is free of particulate matter, microorganisms and other pollutants, and is the key component for maintaining the cleanliness level of the clean room and ensuring the high-quality standard of the production environment.

[0003] In the prior art, a square plate is usually fixedly connected inside the high-efficiency air supply port for mounting the filter. During the air flow process, most of the gas directly moves towards the filter, but a small amount of gas collides with the square plate, causing the dust and impurities carried to adhere to the plate surface. Therefore, when the filter is cleaned regularly, the windward surface (back surface) of the square plate also needs to be cleaned. However, during the cleaning process, the hand needs to be bent and stretched to the windward surface of the square plate for cleaning, which not only causes an awkward and uncomfortable cleaning posture, but also cannot observe the cleaning cleanliness, resulting in missed dead angles and causing the residual dust to be lifted by the airflow in the future, polluting the clean air and causing unnecessary burden to the filter.

[0004] Therefore, we propose an energy-saving large-temperature-difference low-temperature air supply terminal to solve the problems raised in the background art. SUMMARY

One end of a plurality of springs 224 is fixedly connected with one end of a plurality of T-shaped insertion rods 217, every three springs 224 transversely distributed form a group, the other ends of the eight groups of springs 224 are fixedly connected with the outer surfaces of the eight fixed plates 213, every two adjacent T-shaped insertion rods 217 form a group, the other ends of the plurality of groups of T-shaped insertion rods 217 are movably embedded in the interiors of a plurality of fixed holes 215, the interiors of a plurality of moving blocks 218 are provided with two supporting rods 222, one end of every two adjacent supporting rods 222 is movably penetrated to the outer surface of a plurality of wedge-shaped blocks 220, the other end of the plurality of supporting rods 222 is fixedly installed on the inner wall of the square cavity 232, the outer side surface of the eight fixed plates 213 is fixedly installed with a plurality of limiting rods 223, one end of every two adjacent limiting rods 223 is movably penetrated to the outer surface of a plurality of moving blocks 218. The low-temperature box body 301 is connected with the static pressure box body 101 through bolts, the outer surface of the sealing gasket 105 is attached to the other outer surface of the low-temperature box body 301, the high-efficiency filter body 103 is bolted to the other outer surface of the mounting plate 201, the outer surface of the sealing ring 106 is in contact with the other outer surface of the mounting plate 201, the outer surfaces of the four first rubber pads 204 and the four second rubber pads 205 are in contact with the inner wall of the static pressure box body 101, and the outer surface of the mounting plate 201 is fixedly installed in the interior of the static pressure box body 101.

[0041] In this embodiment, when in use, the cooling energy-saving assembly 3 is connected to the air supply assembly 1 by bolts. When cleaning the high-efficiency filter body 103, first remove the cooling energy-saving assembly 3, then remove the high-efficiency filter body 103 from the mounting plate 201, and replace or clean it. Then press the pressing plate 212 at the top position to move it towards the inside of the square cavity 232, and push the wedge block 220 towards the arc-shaped hole 214 through the connecting rod 221. When the wedge block 220 moves on the outer surface of the support rod 222 and inside the moving hole 219, the wedge surface of the wedge block 220 will generate a pushing force on the moving block 218, causing the moving block 218 to move towards the inner wall of the square cavity 232 on the outer surface of the limiting rod 223. In turn, it pulls the movable rod 216 and the T-shaped insertion rod 217 to move, while compressing the spring 224, and slowly pulling the T-shaped insertion rod 217 out of the fixed hole 215, at which time the arc-shaped rod 206 loses its fixation. At the same time that the pressing plate 212 moves, it pushes the top rod 229 to move together, thereby generating a pushing force on the protruding rod 225, causing the first magnet 227 to separate from the second magnet 231, at which time the protruding rod 225 loses its connection. The outer surface of the part where the air guide straight plate 202 is sleeved on the fixed rod 207 is provided with a plurality of tiny protrusions, which increase the resistance and facilitate the rotation of this part, driving the air guide straight plate 202 to rotate around the fixed rod 207 as the center axis. Gently push the bottom of the air guide straight plate 202 to make it rotate around the fixed rod 207 towards the square inside of the mounting plate 201, causing the corresponding first rubber pad 204 to separate from the inner wall of the static pressure tank body 101, and the rubber strips 208 on both sides to separate from the air guide angle plates 203 on both sides, so that the air guide straight plate 202 changes from the original upward inclination to downward inclination. Then pull out the air guide angle plates 203 at the top two corners, causing the protruding rod 225 to be pulled out of the protruding hole 228, so that the air guide angle plates 203 can be removed. Repeat the above operation process to rotate the air guide straight plate 202 at the lower position towards the inside of the mounting plate 201, and remove the air guide angle plates 203 at the lower two corners, then push the air guide straight plates 202 on both sides to the inside of the mounting plate 201. Under the action of the movable air guide assembly 2, the combined air guide straight plate 202 originally expanded in a conical shape can be pushed to the middle to become a concave and gathered structure, so that the windward surface of the side edge faces the staff, facilitating the staff to wipe directly, and the air guide angle plates 203 at the four corners can be quickly removed by a simple plug-in and plug-out method, so that the staff can clean the air guide angle plates 203 directly without bending the wrist, and the cleaning process is more comfortable and relaxed, avoiding the limitations of internal operation, and also allowing real-time observation of the cleaning status of dust and impurities, avoiding missed dead angles, which is conducive to improving the cleaning cleanliness, solving the problem that when the square plate inside the high-efficiency air supply port is regularly cleaned, the hand needs to be bent and stretched to the windward surface of the square plate for cleaning, which not only makes the cleaning posture awkward and uncomfortable, but also makes it impossible to observe the cleaning cleanliness, resulting in missed dead angles and dust residues, which is not conducive to subsequent clean air delivery.

[0042] Furthermore, after cleaning, the pressing plate 212 is pushed first, and then the top air guide plate 202 is pushed to rotate in the opposite direction, making contact with the inner wall of the static pressure box 101 again, so that the arc rod 206 passes through the arc hole 214 and enters the square cavity 232 again. Then, the protruding rods 225 of the two upper air guide angle plates 203 are inserted into the protruding holes 228 again and fitted onto the end of the top rod 229. As the air guide angle plates 203 continue to be pushed, the protruding rods 225 push the top rod 229 to move, and at the same time push the pressing plate 212 to move in the opposite direction, pulling the wedge block 220 to move in the opposite direction. Under the rebound action of the spring 224, the T-shaped insert rod 217 is pushed into the fixing hole 215, thereby fixing the arc rod 206 and the air guide plate 202. At the same time, the first magnet 227 is magnetically attracted to the second magnet 231 again, fixing the two top air guide angle plates 203. Repeat the above method to install the lower air guide plate 202 and air guide angle plate 203. Then push the air guide plates 202 on both sides back to their original positions. The outer surface of the side pressing plate 212 has hook holes. With the help of the hook rod, the side pressing plate 212 can be hooked and moved back to its original position.

[0043] Furthermore, the reset air guide plate 202 and the air guide angle plate 203 form a conical hood structure. The first rubber pad 204 and the second rubber pad 205 seal the edge of the conical hood, improving the sealing between the conical hood and the inner wall of the static pressure box 101. The inclined edge of the conical hood helps to concentrate the airflow and guide it towards the direction of the high-efficiency filter body 103 for better filtration. It can also prevent the airflow from directly colliding with the mounting plate 201, disperse the impact force of the airflow, reduce the risk of deformation and wear of the mounting plate 201, and extend its service life.

One end of one of the fixed pipes 305 is connected with an electric three-way valve 309 through a flange plate. The two ends of the electric three-way valve 309 are connected with connecting pipes 310 through flange plates. A plurality of drainage plates 311 are fixedly installed in the inside of the low-temperature box 301 close to the condensing pipe 304.

The insides of the two water collecting pipes 308 are respectively communicated with the insides of the two water collecting grooves 307. One end of each of the two fixed pipes 305 is fixedly penetrated through the front surface and the rear surface of the low-temperature box 301. The outer surfaces of the two air baffle plates 306 are respectively fixedly connected with the front surface wall and the rear surface wall in the inside of the low-temperature box 301.

[0045] In use, the air delivered by the air conditioning system is adjusted in air volume by the air volume adjusting valve 102, and then uniformly delivered into the static pressure box 101 by the flow uniformizing plate 104, and then guided to the high-efficiency filter body 103 by the movable air guide assembly 2 for air treatment, and then enters the low-temperature box 301. The two connecting pipes 310 are respectively connected with cold water supply equipment and normal-temperature water supply equipment. Cooling medium is injected into the condensing pipe 304 through one of the fixed pipes 305. The filtered gas flows into the air ducts of the condensing pipe 304 through the drainage plates 311, exchanges heat with the cooling medium, reduces the temperature of the gas, and is finally delivered at a large temperature difference and low temperature by the flow diffuser 302. When the temperature difference between the air supply temperature and the indoor temperature is small, large-flow air supply is required, which causes the equipment to be operated at high load for a long time, and the energy consumption is high. By reducing the air supply temperature and increasing the temperature difference, the air supply volume can be greatly reduced, the energy consumption of the fan operation is reduced, and energy-saving large-temperature-difference low-temperature air supply is realized.

[0046] Further, in the low-temperature air supply process, the temperature of the gas is detected by the temperature sensor 303, and the detection result is transmitted to the external control system in the form of an electric signal for identification and analysis. When the air supply temperature is lower than the set temperature target, the control system triggers the electric three-way valve 309 to increase the bypass flow and reduce the amount of cold water injection, thereby increasing the temperature of the cooling medium and the air supply temperature; when the air supply temperature is higher than the set temperature target, the electric three-way valve 309 reduces the bypass flow and increases the amount of cold water injection, thereby reducing the temperature of the cooling medium and the air supply temperature, and intelligently adjusting the low-temperature air supply temperature.

[0047] Further, the condensing pipe 304 is composed of a plurality of special-shaped pipe fittings, such as Figure 3 As shown, the special-shaped pipe fittings are composed of an inclined sharp pipe and a square flat pipe. During cooling, the gas is forced to change the flow direction by the flow guide plate 311, flows to the inclined sharp pipe, and then flows upward along the inclined surface of the inclined sharp pipe, and then enters the air duct of the square flat pipe. The flow guide plate 311 ensures that the gas is in full contact with the condensing pipe 304. The composition of the inclined sharp pipe and the square flat pipe effectively expands the contact area of the gas and the cooling cutoff, improving the cooling effect. The "wedge" structure of the inclined sharp pipe is conducive to smooth transition of the airflow into the air duct of the flat pipe, avoiding resistance and noise caused by airflow sudden change; the rigidity of the square flat pipe is stronger than that of the circular pipe, and it can withstand higher airflow pressure, which is suitable for large air volume air supply port scenes, and the cross-sectional size of the air duct inside the square flat pipe is consistent, and the airflow velocity is uniform, which is conducive to ensuring the consistency of the heat exchange intensity of each area of the flat pipe and improving the uniformity of the gas cooling.

[0048] The overall effect and working principle of the mechanism are as follows: After the air volume is regulated by the air volume regulating valve 102, the air is evenly delivered to the static pressure box 101 by the flow equalization plate 104. The gas is then guided to the high-efficiency filter body 103 for air treatment by the movable air guide assembly 2, and then enters the low-temperature box 301. One of the fixed pipes 305 injects cooling medium into the condenser fitting 304. The filtered gas flows into the air duct of the condenser fitting 304 through the guide plate 311, exchanges heat with the cooling medium, reduces the gas temperature, and finally is delivered by the diffuser 302 for low-temperature air supply with a large temperature difference. Temperature sensor 303 detects the gas temperature and transmits the detection result to the external control system for identification and analysis via an electrical signal. When the supply air temperature is lower than the set temperature target, the control system triggers electric three-way valve 309 to increase the bypass flow and reduce the cold water injection, thereby increasing the cooling medium temperature and the supply air temperature. When the supply air temperature is higher than the set temperature target, electric three-way valve 309 reduces the bypass flow and increases the cold water injection, thereby decreasing the cooling medium temperature and the supply air temperature. The cooling and energy-saving component 3 and the high-efficiency filter body 103 are removed sequentially. Pressing the upper pressing plate 212 pushes the wedge block 220 to move via the connecting rod 221. The wedge surface exerts a thrust on the moving block 218, causing the moving block 218 to pull the movable rod 216 and the T-shaped insert 217 to move. Simultaneously, the spring 224 is compressed, and the T-shaped insert 217 is pulled out of the fixing hole 215. At the same time, the top rod 229 moves along with it, pushing the protruding rod 225 to move, causing the first magnet 227 to separate from the second magnet 231. Move the air guide plate 202 so that it rotates around the fixing rod 207 into the square inward of the mounting plate 201, changing its tilt from upward to downward. Then, pull out the air guide corner plates 203 at the top two corners and remove them. Repeat the above operation, moving the lower air guide plate 202 and removing the air guide corner plates 203. Then, move the air guide plates 202 on both sides into the mounting plate 201. You do not need to bend your wrist; clean with your backhand to avoid missing any corners.

[0049] Among them, the air volume regulating valve 102, the high-efficiency filter body 103, the temperature sensor 303 and the electric three-way valve 309 are all existing technologies, and their components and operating principles are all publicly available technologies, so they will not be explained in detail here.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
