Description

Technical Field

[0001] This utility model relates to the field of tube sheet technology for air drying equipment, specifically a tube sheet structure for the lower layer of air drying equipment. Background Technology

[0002] The lower perforated plate of the air drying equipment refers to the perforated plate located at the bottom of the air drying equipment. It is usually called a dust removal perforated plate or perforated plate. Its main function is to separate different areas of the equipment and provide holes for installing filter bags.

[0003] In traditional air-drying equipment, the lower tube sheet structure is usually connected to the air-drying equipment by welding and screws. Filter bags are fitted onto the inner wall of the tube sheet, and then the filter bag support is inserted into the inner wall of the tube sheet. However, in traditional devices, the external filter bag support needs to be inserted from the opposite direction of the filter bag to help limit and fix the filter bag, which affects the stable installation of the filter bag. Furthermore, when traditional air-drying equipment vibrates during operation, the slide plate tends to vibrate synchronously with the air-drying equipment, which can cause the filter bag to shake and affect its stable operation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lower tube sheet structure for an air-drying device, thereby solving the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a lower tube sheet structure for an air-drying device, comprising an outer sealing plate, an auxiliary plate fixedly mounted on the inner wall of the outer sealing plate near the bottom, a tube sheet body fixedly mounted on the inner wall of the auxiliary plate, a fixed cylinder fixedly mounted on the top of the tube sheet body, a threaded rod rotatably sleeved on the inner wall of the fixed cylinder, a limit wheel fixedly mounted on the side of the threaded rod, a groove formed on the outer edge of the limit wheel, an adjusting plate fixedly mounted on the side of the limit wheel, a clamping plate threadedly connected to the outer edge of the threaded rod, and the side of the clamping plate slidably connected to the inner wall of the fixed cylinder, an inner cylinder fixedly mounted on the top of the auxiliary plate, a sliding cylinder slidably sleeved on the outer edge of the inner cylinder, a top plate fixedly mounted on the top of the sliding cylinder, and a connecting plate fixedly mounted on the top of the top plate, and the side of the connecting plate slidably connected to the side of the inner wall of the outer sealing plate.

[0006] As a preferred embodiment of this utility model, a side plate is fixedly mounted on the side of the fixed cylinder, a cylinder is fixedly mounted on the side of the side plate, a spring is fixedly connected to the side of the inner wall of the cylinder, and a limit rod is fixedly connected to the end of the spring away from the inner wall of the cylinder, and the outer edge of the limit rod is slidably sleeved with the inner wall of the cylinder.

[0007] As a preferred embodiment of this utility model, the outer edge of the limiting wheel is provided with a groove, and the shape and size of the concave surface of the inner wall of the groove are adapted to the shape and size of the convex surface of the outer edge of the limiting rod.

[0008] As a preferred technical solution of this utility model, a positioning plate is fixedly assembled on the inner wall of the clamping plate near the bottom, and the shape and size of the outer edge of the positioning plate are adapted to the shape and size of the inner wall of the flower plate body.

[0009] As a preferred embodiment of this utility model, an outer cylinder is fixedly mounted on the top of the auxiliary plate, and the inner wall of the outer cylinder is slidably sleeved with the outer edge of the slide cylinder. A slide rod is fixedly sleeved on the inner wall of the slide cylinder near the top, and the outer edge of the slide rod is slidably sleeved with the inner wall of the inner cylinder.

[0010] As a preferred embodiment of this utility model, a magnet ring is fixedly mounted at the bottom of the slide cylinder, a coil is fixedly sleeved on the inner wall of the outer cylinder near the bottom, and the inner wall of the coil is slidably sleeved with the outer edge of the magnet ring. A second spring is fixedly connected to the top of the outer cylinder, and the top of the second spring is fixedly connected to the bottom of the top plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The lower tube sheet structure of this air-drying equipment utilizes the cooperation of an adjusting plate and a limiting wheel. The adjusting plate drives the limiting wheel to rotate, which in turn drives the threaded rod to rotate. The threaded rod then drives the side of the clamping plate to slide within the inner wall of the fixed cylinder. When the filter bag is installed onto the inner wall of the tube sheet, the clamping plate moves the positioning plate, which in turn assists the positioning plate and the inner wall of the tube sheet in limiting the filter bag. A spring pushes the limiting rod within the inner wall of the cylinder, allowing the convex surface of the limiting rod to engage with the concave inner wall, thus assisting the limiting wheel in limiting the filter bag.

[0013] 2. The lower tube sheet structure of this air-drying equipment uses a sliding rod and a sliding cylinder to connect the connecting plate to the air-drying equipment. When the air-drying equipment is in operation, the outer edge of the sliding rod slides in the inner wall of the inner cylinder, the outer edge of the sliding cylinder slides in the inner wall of the outer cylinder, and the inner wall of the sliding cylinder slides in the outer edge of the inner cylinder. In turn, the sliding cylinder drives the magnet ring to slide in the inner wall of the coil, and the spring pushes the top plate to move in the opposite direction, thereby reducing the vibration of the tube sheet body. The outer sealing plate assists in reducing the vibration of the tube sheet body while sealing it. Attached Figure Description

[0022] Please see Figures 1-6 A lower tube sheet structure for an air-drying device includes an outer sealing plate 1. An auxiliary plate 2 is fixedly mounted on the inner wall of the outer sealing plate 1 near its bottom. A tube sheet body 3 is fixedly mounted on the inner wall of the auxiliary plate 2. A fixing cylinder 4 is fixedly mounted on the top of the tube sheet body 3. A threaded rod 5 is rotatably sleeved on the inner wall of the fixing cylinder 4. A limit wheel 6 is fixedly mounted on the side of the threaded rod 5. A groove 7 is formed on the outer edge of the limit wheel 6. An adjusting plate 8 is fixedly mounted on the side of the limit wheel 6. A clamping plate 13 is threadedly connected to the outer edge of the threaded rod 5, and the side of the clamping plate 13 is slidably connected to the inner wall of the fixing cylinder 4. An inner cylinder 16 is fixedly mounted on the top of the auxiliary plate 2, and the outer edge of the inner cylinder 16 is slidably sleeved. A sliding cylinder 17 is connected, and a top plate 19 is fixedly mounted on the top of the sliding cylinder 17. A connecting plate 23 is fixedly mounted on the top of the top plate 19. The side of the connecting plate 23 is slidably connected to the side of the inner wall of the outer sealing plate 1. Through the cooperation of the threaded rod 5 and the limiting wheel 6, the adjusting plate 8 drives the limiting wheel 6 to rotate, and then the limiting wheel 6 drives the threaded rod 5 to rotate. Then the threaded rod 5 drives the side of the clamping plate 13 to slide in the inner wall of the fixed cylinder 4. Through the addition of the connecting plate 23, the connecting plate 23 is connected to the drying equipment. Then the inner wall of the sliding cylinder 17 slides on the outer edge of the inner cylinder 16, thereby assisting the limiting movement of the tube sheet body 3.

[0023] In a preferred embodiment, a side plate 9 is fixedly mounted on the side of the fixed cylinder 4, and a cylinder 10 is fixedly mounted on the side of the side plate 9. A spring 11 is fixedly connected to the side of the inner wall of the cylinder 10, and a limiting rod 12 is fixedly connected to the end of the spring 11 away from the inner wall of the cylinder 10. The outer edge of the limiting rod 12 is slidably sleeved with the inner wall of the cylinder 10. Through the cooperation of the cylinder 10 and the spring 11, the spring 11 pushes the limiting rod 12 to move in the inner wall of the cylinder 10, and then the convex surface of the limiting rod 12 is limited by the inner wall of the groove 7, which in turn helps the limiting wheel 6 to limit the movement.

[0024] In a preferred embodiment, the outer edge of the limiting wheel 6 is provided with a groove 7, and the shape and size of the concave surface of the inner wall of the groove 7 are adapted to the shape and size of the convex surface of the outer edge of the limiting rod 12. Through the cooperation of the limiting wheel 6 and the groove 7, there are several grooves 7. As the limiting wheel 6 rotates, the grooves 7 adjacent to the limiting rod 12 fit with the convex surface of the limiting rod 12, thereby assisting the limiting wheel 6 to stabilize and limit the position.

[0025] In a preferred embodiment, a positioning plate 14 is fixedly mounted on the inner wall of the clamping plate 13 near the bottom, and the shape and size of the outer edge of the positioning plate 14 are adapted to the shape and size of the inner wall of the tube sheet body 3. Through the cooperation of the positioning plate 14 and the clamping plate 13, the clamping plate 13 drives the positioning plate 14 to move under the drive of the threaded rod 5, thereby using the outer edge of the positioning plate 14 and the inner wall of the tube sheet body 3 to clamp the filter bag, thereby assisting in the stable clamping and limiting of the filter bag.

[0026] In a preferred embodiment, an outer cylinder 15 is fixedly mounted on the top of the auxiliary plate 2, and the inner wall of the outer cylinder 15 is slidably sleeved with the outer edge of the slide cylinder 17. A slide rod 18 is fixedly sleeved on the inner wall of the slide cylinder 17 near the top, and the outer edge of the slide rod 18 is slidably sleeved with the inner wall of the inner cylinder 16. Through the cooperation of the outer cylinder 15 and the slide cylinder 17, the outer edge of the slide cylinder 17 slides in the inner wall of the outer cylinder 15, and drives the outer edge of the slide rod 18 to slide in the inner wall of the inner cylinder 16, thereby further limiting the movement of the flower plate body 3 through the auxiliary plate 2.

[0027] In a preferred embodiment, a magnet ring 21 is fixedly mounted on the bottom of the slide cylinder 17, and a coil 22 is fixedly sleeved on the inner wall of the outer cylinder 15 near the bottom. The inner wall of the coil 22 is slidably sleeved with the outer edge of the magnet ring 21. A spring 20 is fixedly connected to the top of the outer cylinder 15, and the top of the spring 20 is fixedly connected to the bottom of the top plate 19. Through the cooperation of the magnet ring 21 and the coil 22, the magnet ring 21 moves with the slide cylinder 17. When the outer edge of the magnet ring 21 slides in the inner wall of the coil 22, the coil 22 generates electromagnetic damping on the magnet ring 21. The spring 20 assists in pushing the outer cylinder 15 downward, thereby assisting in the shock absorption of the tube sheet body 3 and preventing the filter bag from becoming loose when it is mounted on the inner wall of the tube sheet body 3.

[0028] Working principle: When the device is in use, the adjusting plate 8 drives the limiting wheel 6 to rotate, which in turn drives the threaded rod 5 to rotate. The threaded rod 5 then drives the side of the clamping plate 13 to slide within the inner wall of the fixed cylinder 4. When the filter bag is installed on the inner wall of the tube sheet body 3, the clamping plate 13 drives the positioning plate 14 to move, thus assisting the positioning plate 14 and the inner wall of the tube sheet body 3 in limiting the filter bag. A spring 11 pushes the limiting rod 12 within the inner wall of the cylinder 10, thereby utilizing the convex and concave surfaces of the limiting rod 12... The inner walls are fitted together, and the auxiliary limiting wheel 6 limits the connection. The connecting plate 23 is connected to the drying equipment. When the drying equipment is in operation, the outer edge of the slide rod 18 slides in the inner wall of the inner cylinder 16, the outer edge of the slide cylinder 17 slides in the inner wall of the outer cylinder 15, and the inner wall of the slide cylinder 17 slides in the outer edge of the inner cylinder 16. Then, the slide cylinder 17 drives the magnet ring 21 to slide in the inner wall of the coil 22, and the spring 20 pushes the top plate 19 to move in the opposite direction, thereby reducing the vibration of the tube sheet body 3. The outer sealing plate 1 assists in reducing the vibration of the tube sheet body 3 and seals it at the same time.
