Description

Technical Field

[0001] This utility model relates to the field of cleanroom exhaust devices, specifically a cleanroom exhaust treatment device. Background Technology

[0002] Cleanrooms are special enclosed spaces with precise environmental parameter control capabilities. Their core function is to strictly control airborne particles, harmful gases, and airflow organization through technologies such as air filtration, temperature and humidity regulation, and air pressure balancing to ensure that the room maintains a specific cleanliness level. These spaces are widely used in semiconductor manufacturing, pharmaceutical research and development and production, biological laboratories, precision electronic assembly, and other fields.

[0003] To prevent pollutants from leaking out of the cleanroom through the exhaust system, or to prevent outside air from flowing back into the cleanroom through the exhaust ducts and affecting the cleanliness of the room, the exhaust duct ports of cleanrooms are usually equipped with dedicated filter units. These filter units often use a combination structure of plateless high-efficiency filters, which can specifically intercept residual particles and harmful substances in the exhaust air. This not only meets environmental emission standards, but also prevents pollutants in the exhaust system from spreading back into the cleanroom, ensuring the stability of the overall cleanroom environment.

[0004] Currently, the installation method of filter units and exhaust duct ports is significantly inconvenient. Filter units typically weigh around 5kg, while exhaust duct ports are often installed at higher positions such as walls or ceilings. During installation, operators need to continuously lift the filter unit with one hand until it is flush with the inner wall of the duct port, while using the other hand to hold an electric wrench to bolt the filter unit frame to the inner wall of the duct. Prolonged lifting can easily cause arm pain, and the filter may also shift due to the operator's single-handed operation, affecting the accuracy of bolt tightening and thus impacting the installation of the high-efficiency filter. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a cleanroom exhaust air treatment device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cleanroom exhaust ventilation device, comprising an air duct, a duct compartment at the port of the air duct, two sets of support components and fixing components installed on the inner wall of the duct compartment, the support component including a first mounting plate, a support rod movably disposed inside the first mounting plate, a hanger and a first limiting block respectively fixed at both ends of the support rod, the fixing component including a lead screw, fasteners and fixing members movably disposed on the outer wall of the lead screw, a second mounting plate fixed at the end of the fixing member, a filter installed in the duct compartment, a frame plate fixed on the outer wall of the filter, and an air guide plate installed at the end of the duct compartment.

[0007] By adopting the above technical solution, the problem of arm pain caused by the long-term lifting of personnel due to the traditional bolt-fixing method of high-efficiency filters is solved. After the personnel lift the filter into the air duct, they rotate and adjust the two sets of brackets inside the duct compartment so that the two sets of brackets can support the filter when the personnel loosen the filter. Then, the personnel rotate the screw so that the two sets of fasteners inside the duct compartment can press the frame plate outside the filter to achieve the fixed installation of the filter.

[0008] The present invention is further configured such that both the first mounting plate and the second mounting plate are L-shaped, and the first mounting plate and the second mounting plate are welded and fixed to the inner wall of the tube compartment.

[0009] Preferably, one end of the L-shaped first mounting plate and the second mounting plate are fixedly welded to the inner wall of the tube compartment, and the other end is used to connect the support rod and the lead screw.

[0010] The present invention is further configured such that the interior of the tube compartment is provided with a groove, and the shape of the groove matches the shape of the frame plate, and the width of the groove is 5mm greater than the thickness of the frame plate.

[0011] Preferably, when a person lifts the filter with both hands, the person can visually adjust the filter by measuring the distance between the frame plate and the four walls of the tube compartment. Then, the frame plate can be pushed and slid slowly to make it fit into the groove. The tube compartment limits the frame plate through the groove, so that the filter will not be misaligned or shifted during the fixing process.

[0012] The present invention is further provided that a sealing gasket is fixedly disposed inside the groove, and the sealing gasket is made of silicone rubber.

[0013] Preferably, after the filter is fixedly installed, the outer frame of the filter fits tightly with the sealing gasket inside the groove, so that all the gas discharged from the air duct can be filtered by the filter.

[0014] The present invention is further provided that the top of the hanging piece is provided with a protruding plate, and the protruding plate is configured in an L-shape.

[0015] Preferably, after the personnel insert the filter frame into the groove, they can rotate the hanger. After the hanger rotates, the L-shaped protrusion on the hanger will contact the wall of the frame, thus indicating to the personnel that the hanger has been rotated to the position directly below the frame.

[0016] The present invention is further configured such that the distance between the hanger and the first mounting plate is 3mm greater than the height of the frame plate.

[0017] Preferably, when the filter can be released, the filter will fall downwards due to its own weight, and the two sets of hangers will support the filter under force. When the filter falls to the lowest position, the top of the outer frame plate of the filter is still inside the groove.

[0018] The present invention is further configured such that the thread structure of the lead screw is a trapezoidal thread, the thread structure of the inner wall of the fixing member matches the lead screw, the outer wall of the lead screw is fitted with a compression ring, and the two ends of the lead screw are respectively provided with a rotating lug and a second limiting block.

[0019] Preferably, the thread helix angle provided on the outer wall of the lead screw and the inner wall of the fastener is smaller than the equivalent friction angle of its thread surface, so that the lead screw can press and fix the fastener by pushing the compression ring.

[0020] The present invention is further configured such that the inner wall size of the fastener and the extrusion ring is larger than the outer wall size of the lead screw, and a retaining plate is provided at one end of the fastener.

[0021] Preferably, after the filter is fixedly installed, the two sets of fasteners limit the inner wall of the frame plate through the clamping plates set at their ends, so that the filter will not move horizontally inside the pipe compartment.

[0022] In summary, the present invention has the following main advantages: 1. This utility model solves the problem of arm pain caused by the traditional bolt-fixed high-efficiency filter method, which requires personnel to lift it for a long time, by setting up an air duct, support components, fixing components, filter, frame plate and groove. After the personnel lift the filter into the air duct, they rotate and adjust the two sets of brackets inside the duct compartment so that when the personnel release the filter, the two sets of brackets can support the filter. Then, the personnel rotate the screw so that the two sets of fasteners inside the duct compartment can press the frame plate outside the filter to fix the filter in place.

[0023] 2. This utility model solves the problem of misalignment that easily occurs during the installation of high-efficiency filters by setting up hangers, protruding plates, grooves, filters, and frame plates. The inside of the tube compartment has a groove that matches the shape of the frame plate on the outside of the filter. When the personnel lift the filter with both hands, they can make preliminary adjustments to the filter by visually judging the distance between the frame plate and the four walls of the tube compartment. Then, the frame plate can be pushed and slid slowly to make the frame plate fit into the groove. The tube compartment limits the frame plate through the groove, so that the filter will not be misaligned or shifted during the fixing process. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] Please see Figure 1 — Figure 7The system includes a duct 1, with a duct housing 101 at its port. Two sets of support and fixing components are installed on the inner wall of the duct housing 101. The support components include a first mounting plate 304, with a support rod 302 movably mounted inside the first mounting plate 304. Hangers 3 and first limiting blocks 303 are fixed to both ends of the support rod 302, respectively. The fixing components include a lead screw 402, with fasteners 4 and fixing members 407 movably mounted on the outer wall of the lead screw 402. A second mounting plate 406 is fixed to the end of the fixing member 407. A filter 5 is installed in the duct housing 101. A frame plate 501 is fixed to the wall, and an air guide plate 2 is installed at the end of the duct 101. This solves the problem of arm pain caused by the traditional bolt-fixed high-efficiency filter requiring long-term lifting. After the personnel lift the filter 5 into the air duct 1, they rotate and adjust the two sets of hangers 3 inside the duct 101 so that the two sets of hangers 3 can support the filter 5 when the personnel release it. Then, by rotating the screw 402, the personnel make the two sets of fasteners 4 inside the duct 101 press against the frame plate 501 outside the filter 5 to achieve the fixed installation of the filter 5.

[0029] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 , Figure 4 and Figure 6 The first mounting plate 304 and the second mounting plate 406 are both L-shaped. The first mounting plate 304 and the second mounting plate 406 are welded and fixed to the inner wall of the tube compartment 101. One end of the L-shaped first mounting plate 304 and the second mounting plate 406 is fixedly welded to the inner wall of the tube compartment 101, and the other end is used to connect the support rod 302 and the lead screw 402.

[0030] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 3 The interior of the tube compartment 101 is provided with a groove 102, and the shape of the groove 102 matches the shape of the frame plate 501. The width of the groove 102 is 5mm larger than the thickness of the frame plate 501. When the personnel lift the filter 5 with both hands, they can visually adjust the filter 5 by judging the distance between the frame plate 501 and the four walls of the tube compartment 101. Then, the frame plate 501 can be pushed and slid slowly to make the frame plate 501 fit into the groove 102. The tube compartment 101 limits the frame plate 501 through the groove 102, so that the filter 5 will not be misaligned or shifted during the fixing process.

[0031] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 A sealing gasket 103 is fixedly installed inside the groove 102, and the sealing gasket 103 is made of silicone rubber. After the filter 5 is fixedly installed, the frame plate 501 outside the filter 5 fits tightly with the sealing gasket 103 inside the groove 102, so that the gas discharged from the air duct 1 can be filtered by the filter 5.

[0032] For details regarding the above embodiments, please refer to [link / reference]. Figure 6 The top of the hanger 3 is provided with a protruding plate 301, which is L-shaped. When the personnel insert the frame plate 501 of the filter 5 into the groove 102, the personnel can rotate the hanger 3. When the hanger 3 is rotated 90 degrees, the L-shaped protruding plate 301 on the hanger 3 will contact the wall surface of the frame plate 501, thereby indicating to the personnel that the hanger 3 has been rotated to the position directly below the frame plate 501.

[0033] For details regarding the above embodiments, please refer to [link / reference]. Figure 6 and Figure 7 The distance between the hanger 3 and the first mounting plate 304 is 3mm greater than the height of the frame plate 501. When the personnel can loosen the filter 5, the filter 5 will fall downward due to its own weight. The two sets of hangers 3 support the filter 5. When the filter 5 falls to the lowest position, the top of the outer frame plate 501 of the filter 5 is still inside the groove 102.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 and Figure 5 The thread structure of the lead screw 405 is set as a trapezoidal thread. The thread structure of the inner wall of the fastener 407 matches that of the lead screw 405. The outer wall of the lead screw 405 is fitted with a compression ring 405. The two ends of the lead screw 405 are respectively provided with a rotating lug 404 and a second limiting block 403. The thread helix angle on the outer wall of the lead screw 405 and the inner wall of the fastener 407 is smaller than the equivalent friction angle of its thread surface, so that the lead screw 405 can compress and fix the fastener 4 by pushing the compression ring 405.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The inner wall dimensions of fastener 4 and extrusion ring 405 are larger than the outer wall dimensions of screw 402. One end of fastener 4 is provided with a clamping plate 401. After the filter 5 is fixedly installed, the two sets of fasteners 4 limit the inner wall of frame plate 501 through the clamping plate 401 at their ends, so that the filter 5 will not move horizontally inside the tube compartment 101.

[0036] In practical operation, when the filter 5 is fixedly installed at the air outlet end of the duct 1, the operator first rotates and adjusts the two sets of hangers 3 and two sets of fasteners 4 inside the end compartment 101 of the duct 1 so that the hangers 3 and fasteners 4 are parallel to the first mounting plate 304 and the second mounting plate 406 at their ends in the vertical plane. Then, the operator lifts the filter 5 upwards into the compartment 101 with both hands and inserts the frame plate 501 fitted on one side of the filter 5 into the groove 1 of the compartment 101. In step 02, the filter 5 covers the pipe opening inside the pipe compartment 101. After the frame plate 501 is inserted into the groove 102, the operator supports and fixes the filter 5 with one hand and rotates the two sets of hangers 3 with the other hand so that the two sets of hangers 3 are perpendicular to the first mounting plate 304 on the top in the vertical plane. After the two sets of hangers 3 have been rotated and adjusted, the operator can release the filter 5. The filter 5 falls downward due to its own weight, and the two sets of hangers 3 support the filter 5. The L-shaped brackets on one side of the outer wall of the hangers 3 provide support. The protruding plate 301 is secured to the outer wall of the outer frame plate 501 of the filter 5. Then, the operator rotates the two sets of fasteners 4 by 90 degrees to adjust them so that the retaining plate 401 at the end of the fastener 4 corresponds to the inner wall of the frame plate 501. Then, the operator holds the direction of the fastener 4 with one hand and rotates the rotating lug 404 with the other hand. The lug 404 drives the lead screw 402 to rotate. Since the lead screw 402 is connected to the inner wall of the fixing part 407 through a threaded structure, the lug 404 slowly pushes the fastener 4 through the compression ring 405. Moving the fastener 4 towards the frame plate 501, the fastener 4 can lift the filter 5 upward, so that the frame plate 501 outside the filter 5 fits tightly with the sealing gasket 103 inside the groove 102, so that the two sets of fasteners 4 can fix the filter 5 by pressing the frame plate 501. Finally, align the arc-shaped protrusions on the four sides of the air guide plate 2 with the outer wall of the air duct 1 port, and fix the arc-shaped protrusions of the air guide plate 2 to the air duct 1 port by pressing and pushing, thus completing the installation and fixing of the filter 5.
