Description
Technical Field
[0001] This utility model relates to the field of drying tank covers, and in particular to a novel drying tank cover. Background Technology
[0002] As a crucial component in industrial production, drying tank covers are widely used in drying systems across various industries, including chemical, food, and pharmaceutical. Their primary function is to protect and seal the drying tank, ensuring airflow and temperature control within a reasonable range. This improves drying efficiency, reduces energy consumption, and guarantees the quality of dried materials. However, with increasing demands for production efficiency and environmental protection across industries, traditional drying equipment has gradually revealed shortcomings such as poor sealing performance, low energy efficiency, and complex operation. Therefore, the technology of drying tank covers is constantly being innovated to meet the needs of modern production processes.
[0003] Existing technologies, such as the utility model patent with publication number CN216770007U, disclose a synchronous opening mechanism for drying tank covers. This patent includes a synchronous opening mechanism for drying tank covers, with movable tank covers slidably connected to both sides of the top of the drying tank body. The synchronous opening mechanism body is installed on the front and rear sides of the drying tank body. The drying tank body includes a slide rail, connecting sliders, a drive cylinder, and a synchronous belt. The connecting sliders are slidably connected to the outer surface of the slide rail. The top ends of two sets of connecting sliders are fixedly installed to two sets of movable tank covers, and the bottom ends of the two sets of connecting sliders are fixedly connected to the upper and lower sides of the synchronous belt, respectively. The output end of the drive cylinder is fixedly connected to one set of connecting sliders. This synchronous opening mechanism for drying tank covers reduces the switching stroke, ensures the synchronicity of the opening and closing of the two tank covers, saves costs, and reduces the overall size of the drying tank.
[0004] In the prior art, when using a drying tank cover to protect and seal the cleaned baskets and silicon wafers, the drying tank cover mainly serves to keep warm and prevent dust. It often cannot effectively prevent the residue of the chemical solution on the wet baskets and pressure rods. This residue of chemical solution can easily drip onto the surface of the silicon wafers, causing defects such as watermarks, wafer sticking, or fragmentation, which affects the surface quality of the silicon wafers and the subsequent processing effect. Utility Model Content
[0005] The purpose of this invention is to address the problem in the existing technology where, when using a drying tank cover to protect and seal cleaned baskets and silicon wafers, the cover primarily serves to insulate and prevent dust, often failing to effectively prevent residual chemicals from the wet baskets and pressure rods. These residual chemicals can easily drip onto the silicon wafer surface, causing watermarks, wafer sticking, or fragmentation, thus affecting the surface quality of the silicon wafers and subsequent processing effects. Therefore, a novel drying tank cover is proposed.

[0029] In the embodiments of this utility model, please refer to Figures 2 to 5The adjustment structure 5 includes a first air duct 501, which is fixedly connected to a reinforcing rib 3. An air inlet 502 is fixedly connected to one side of the first air duct 501. A second air duct 503 is fixedly connected to the arc surface of the first air duct 501. A positioning block 504 is installed on the arc surface of the second air duct 503. The positioning block 504 is fixedly connected to a carbon fiber channel cover 4. A fixing sleeve 505 is fixedly connected to the arc surface of the second air duct 503. A nozzle 506 is slidably connected to the inner wall of the fixing sleeve 505. Two telescopic rods 507 are fixedly connected to the arc surface of the fixing sleeve 505. A connecting block 508 is fixedly connected to the other end of each telescopic rod 507. A spring 509 is fitted onto the arc surface of each telescopic rod 507, and both ends of the spring 509 are respectively connected to the connecting block 508. The nozzle 506 is fixedly connected to the fixed sleeve 505. An auxiliary block 510 is fixedly connected to one side of the connecting block 508, and a fixed plate 511 is fixedly connected to one side of the auxiliary block 510. Several positioning rods 512 are fixedly connected to the arc surface of the nozzle 506, with two positioning rods forming a group. Each group of positioning rods 512 is slidably connected to the fixed plate 511. Two limiting blocks 513 are fixedly connected to the arc surface of the nozzle 506. An insert block 514 is slidably connected to the inner wall of the limiting block 513. The insert block 514 is fixedly connected to the fixed sleeve 505. A fixed rod 517 is fixedly connected to the arc surface of the fixed sleeve 505. A ball bearing 516 is fixedly connected to the other end of the fixed rod 517. A welding block 515 is movably connected to the arc surface of the ball bearing 516. A screw 518 is threaded onto one side of the nozzle 506. An adjustment structure 5 can be used to enhance the drying function of the carbon fiber trough cover 4, aligning it with the contact point between the wet basket and the pressure rod to accelerate air circulation within the trough, increasing the drying effect and preventing residual chemicals from dripping onto the silicon wafers, thus preventing watermarks, wafer sticking, or fragmentation. A connecting frame 522 is fixedly connected to one side of the nozzle 506. A rotating rod 523 is rotatably connected to the inner wall of the connecting frame 522. A connecting plate 524 is fixedly connected to the arc surface of the rotating rod 523. Two coil springs 525 are sleeved on the arc surface of the rotating rod 523. The two ends of the coil springs 525 are fixedly connected to the connecting plate 524 and the connecting frame 522, respectively. A cover plate 526 is fixedly connected to the lower surface of the connecting plate 524. A connecting block 527 is fixedly connected to one side of the nozzle 506. The connecting block 527 and the inner wall of the cover plate 526 are slidably connected to the same fixing frame 528. When the nozzle 506 needs to be protected, the cover plate 526 is rotated first, causing the connecting plate 524 to rotate. The connecting plate 524 then drives the rotating rod 523 to rotate inside the connecting frame 522. While rotating, the connecting plate 524 also drives the coil spring 525 to rotate. When the cover plate 526 is in contact with the nozzle 506, the fixing frame 528 is moved so that the fixing frame 528 is inserted into the interior of the connecting block 527 and the cover plate 526. At this time, the cover plate 526 is fixed, effectively preventing the nozzle 506 from becoming clogged due to dust accumulation during static placement. A limit rope 529 is fixedly connected to one side of the fixing frame 528.The other end of the limiting rope 529 is fixedly connected to the nozzle 506.

The two ends of the bellows 519 are fixedly connected to the connecting block 508 and the fixing sleeve 505, respectively. The bellows 519 can protect the spring 509 to prevent foreign objects from getting stuck. An auxiliary ring 520 is fixedly connected to one side of the connecting block 508. The auxiliary ring 520 has a circular cross-section and can move the connecting block 508, achieving convenient control of the connecting block 508. A soft pad 521 is fixedly connected to the inner wall of the fixing plate 511. The soft pad 521 is a rubber pad. The soft pad 521 can prevent the fixing plate 511 from directly contacting the nozzle 506, preventing damage to the nozzle 506.
[0030] The working principle of the novel drying tank cover provided by this utility model is as follows: By setting the adjustment structure 5, the connecting block 508 is first moved with the help of the auxiliary ring 520, so that the connecting block 508 drives the spring 509 and the telescopic rod 507 to stretch. When the connecting block 508 moves, it will drive the auxiliary block 510 to move. The auxiliary block 510 will then drive the fixed plate 511 to move. Next, the nozzle 506 is moved and inserted into the fixed sleeve 505. When the nozzle 506 moves, it will also drive the limiting block 513 to move, so that the limiting block 513 is inserted into the insert block 514. Then, the auxiliary ring 520 is released. When the auxiliary ring 520 is released, due to the action of the spring 509, the auxiliary ring 520 will be released. The connecting block 508 will move, and at the same time, the connecting block 508 will drive the fixing plate 511 to move, so that the fixing plate 511 is inserted into the positioning rod 512. At this time, the nozzle 506 is fixed to the fixing sleeve 505 on the second air duct 503. Then, the nozzle 506 is rotated to drive the fixing rod 517 to rotate. The fixing rod 517 drives the ball 516 to rotate inside the welding block 515. When the nozzle 506 rotates to the appropriate position, the screw 518 inside the welding block 515 is rotated to fix the screw 518 to the ball 516. At the same time, the positioning block 504 can position the second air duct 503. Then, the carbon fiber trough cover 4 is covered on the assembly. Position the device appropriately and connect it to the air inlet 502. Nitrogen gas is then blown into the first duct 501 through the device. The nitrogen then enters the second duct 503 from the first duct 501 until it is sprayed from the nozzle 506, aiming at the contact point between the wet basket and the pressure rod. When protection of the nozzle 506 is required, first rotate the cover plate 526 to rotate the connecting plate 524. The connecting plate 524 then rotates the rotating rod 523 inside the connecting frame 522. Simultaneously, the rotating plate 524 also rotates the coil spring 525. When the cover plate 526 is in contact with the nozzle 506, move the fixing frame 528 to secure it. The fixed frame 528 is inserted into the interior of the connecting block 527 and the cover plate 526. At this time, the cover plate 526 is fixed, which effectively prevents the nozzle 506 from being blocked due to dust accumulation during the static process. The limiting rope 529 can limit the fixed frame 528 to prevent it from being lost. The corrugated pipe 519 can protect the spring 509 to prevent foreign objects from getting stuck in it. The auxiliary ring 520 can drive the connecting block 508 to move, which facilitates the control of the connecting block 508. The soft pad 521 can prevent the fixed plate 511 from directly contacting the nozzle 506, thus preventing damage to the nozzle 506.
