Description

Technical Field

[0001] The utility model relates to the technical field of monitoring, in particular to a replaceable air supply outlet. Background Art

[0002] High-efficiency air supply outlets are ideal terminal filtration devices for thousand-level, ten-thousand-level, and one-hundred-thousand-level purification and air-conditioning systems, and can be widely used in purification and air-conditioning systems in the pharmaceutical, sanitary, electronic, chemical and other industries. High-efficiency air supply outlets are terminal filtration devices used for the renovation and construction of clean rooms of levels 1000-300000, and are key equipment to meet purification requirements. High-efficiency air supply outlets include static pressure boxes, diffuser plates, and high-efficiency filters. The interface with the air duct can be top-connected or side-connected. The sealing of the high-efficiency filter installation frame is the key to the high-efficiency air supply outlet. Frame sealing defects will cause leakage of the installation frame, which will affect the cleanliness of the clean room. Existing high-efficiency air outlets are usually not easy to replace, and are too complicated to clean and repair, which is not conducive to use.

[0003] For example, a replaceable high-efficiency air supply outlet (publication number: CN211424651U) disclosed in a Chinese patent document, although this patent can quickly disassemble and assemble the diffuser plate through an elastic locking device, and can quickly disassemble and assemble the filter through a quick locking device, the process does not require the aid of tools and the disassembly and assembly are fast, which can shorten the clean room downtime caused by the replacement operation and reduce unnecessary losses.

[0004] However, when disassembling the filter, one hand is required to hold the filter and the other hand to rotate the supporting block, which is a cumbersome operation. Although the quick lock device can quickly install the filter, the vibration generated during work during long-term use can easily cause the handle to loosen, thereby causing the filter to loosen.

A connecting block 9 is fixedly connected to the outer surface of the movable block 8. One end of the connecting block 9 passes through the through groove 7 and extends to the outer surface of the guide tube 5.

[0027] The lower surface of the movable block 8 is provided with a rotation fixing device, and the rotation fixing device includes a rotating rod 10, and the outer surface of one end of the rotating rod 10 is installed with the lower surface of the movable block 8 through a bearing.

[0028] The other end of the rotating rod 10 is fixedly connected to a driving rod 101, and the outer surface of the driving rod 101 is movably sleeved with the inner wall of the guide tube 5. The outer surface of the driving rod 101 is fixedly connected to a guide slide rod 102, and the outer surface of the guide slide rod 102 is slidably inserted into the inner wall of the curved slide groove 6. The guide slide rod 102 cooperates with the curved slide groove 6 to guide the rotation of the driving rod 101 when it is lifted and moved. One end of the driving rod 101 is fixedly connected to a fixed block 103, and the upper surfaces of the two fixed blocks 103 are both provided with a high-efficiency filter body 104. The lifting and rotation of the driving rod 101 drives The fixed block 103 moves synchronously, so that the fixed block 103 rotates when the high-efficiency filter body 104 is disassembled, which is convenient for disassembly and removal. The upper surface of the high-efficiency filter body 104 contacts the lower surface of the sealing frame 4. The inner walls on both sides of the box body 1 are fixedly installed with symmetrically distributed servo electric cylinders 105. One end of the piston rod of the servo electric cylinder 105 is fixedly connected to the lower surface of the connecting block 9. The servo electric cylinder 105 drives the connecting block 9 to upgrade and move. The upper surface of the diffuser plate 2 contacts the lower surface of the box body 1, and the two side surfaces of the diffuser plate 2 are provided with distributed installation grooves 106.

[0029] The inner wall of the mounting groove 106 is hinged with a pressure sleeve 107 through a pin shaft, and a movable rod 108 is movably sleeved on the inner wall of the pressure sleeve 107. A reset spring 109 is fixedly connected to the lower surface of the movable rod 108, and one end of the reset spring 109 is fixedly connected to the inner bottom wall of the pressure sleeve 107. A pull ring 1010 is fixedly connected to the upper surface of the movable rod 108. The pull ring 1010 facilitates the movement of the movable rod 108. The outer surface of the pressure sleeve 107 is provided with travel grooves 1011 distributed in a ring array. The outer surface of the movable rod 108 is fixedly connected with L-shaped pressure rods 1012 distributed in a circular array, one end of the L-shaped pressure rod 1012 passes through the stroke groove 1011 and extends to the outer surface of the pressure sleeve 107, and one end of the multiple L-shaped pressure rods 1012 is fixedly connected with an annular pressure plate 1013, and the lower surface of the annular pressure plate 1013 contacts the upper surface of the positioning plate 3. The elastic force of the reset spring 109 drives the annular pressure plate 1013 to contact and squeeze the positioning plate 3 through the movable rod 108 and the L-shaped pressure rod 1012.

[0030] By providing a rotating fixing device, it is easy to disassemble and assemble the high-efficiency filter body 104, reducing the difficulty of disassembly and assembly, and the stability during installation is high. The convenient disassembly and assembly makes subsequent maintenance, cleaning and replacement easier.

[0031] Working principle: Step 1, during disassembly, the movable rod 108 is driven to move upward through the pull ring 1010, and the upward movement of the movable rod 108 drives the annular pressure plate 1013 to separate from the positioning plate 3 through the L-shaped pressure rod 1012. At this time, the diffuser plate 2 can be disassembled and removed by rotating the pressure sleeve 107 with the cooperation of the pin shaft, and then the high-efficiency filter body 104 is supported by hand and the piston rod of the servo electric cylinder 105 is started to retract. The retraction of the piston rod of the servo electric cylinder 105 drives the movable block 8 to move downward through the connecting block 9, and the downward movement of the movable block 8 drives the driving rod 101 to move downward through the rotating rod 10. The downward movement of the driving rod 101 is rotated and descended through the cooperation of the guide slide bar 102 and the curved slide groove 6, thereby driving the fixed block 103 to rotate and descend to separate from the high-efficiency filter body 104 and then can be disassembled and removed;

[0032] Step 2: During installation, support the high-efficiency filter body 104 by hand until the upper end contacts the sealing frame 4, then start the servo electric cylinder 105 piston rod to extend and move, drive the movable block 8 to move upward through the connecting block 9, and the upward movement of the movable block 8 drives the driving rod 101 to move upward through the rotating rod 10, and the upward movement of the driving rod 101 is rotated and raised through the cooperation of the guide slide bar 102 and the curved slide groove 6, thereby driving the fixed block 103 to rotate and rise to stably support the high-efficiency filter body 104;

[0033] Step three, when installing the diffuser plate 2, first fit the diffuser plate 2 under the box body 1, and then drive the movable rod 108 to move through the pull ring 1010, and the movement of the movable rod 108 drives the annular pressure plate 1013 to move through the L-shaped pressure rod 1012. At this time, the reset spring 109 is stretched, and then the pressure sleeve 107 is rotated through the cooperation of the pin shaft to rotate the annular pressure plate 1013 to the top of the positioning plate 3. At this time, the pull ring 1010 is released, and the movable rod 108 is driven to reset and move by the pressure of the reset spring 109, thereby driving the annular pressure plate 1013 and the positioning plate 3 to be squeezed by the L-shaped pressure rod 1012, and the diffuser plate 2 and the lower end of the box body 1 are squeezed and sealed by elastic extrusion to improve the sealing performance.
