[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] See Figure 1 This embodiment discloses a screen cleaning device, including a settling platform 1, a settling tank disposed on top of the settling platform 1, an auxiliary cleaning assembly connected to the top of the settling platform 1, and a matching screen cleaning basket 2. The settling platform 1 serves as the supporting structure of the entire device, and its top surface has multiple sets of settling tanks arranged side-by-side to hold cleaning fluid, spraying fluid, and condensate from the drying process. The settling platform 1 is made of corrosion-resistant material to ensure structural stability during long-term use.

[0025] Combination Figure 3In this embodiment, the screen cleaning basket 2 is constructed as a square basket-shaped structure formed by multiple sets of railings 21 hinged together. Multiple sets of spaced-apart partitions 22 are provided inside the basket-shaped cavity, dividing the cavity into multiple equidistant spaces to simultaneously support multiple sets of screens and prevent the screens from colliding and being damaged during the cleaning process. At least one side of the screen cleaning basket 2 is constructed as an openable door structure for easy and quick loading and unloading of the screens. Multiple sets of lifting rings 23 are fixedly connected to the top of the screen cleaning basket 2 for connection to auxiliary cleaning components; its bottom is also equipped with casters 24 with braking function for easy movement by workers.

[0026] See Figure 2 Furthermore, the settling tanks on the top surface of the settling platform 1 include at least a washing tank 3, a spray tank 4, and a drying tank 5. These settling tanks are arranged side-by-side on one side of the settling platform 1 to facilitate smooth transitions between processes and form a continuous cleaning flow. Each settling tank is equipped with walking steps 6 to allow personnel to enter the tank for equipment maintenance and cleaning. A unified water inlet pipe 7 is connected to the upper end of each settling tank, and a unified drainage pipe 8 is connected to the lower end.

[0027] An ultrasonic vibrator 9 is connected to the inner wall of the cleaning tank 3. The ultrasonic vibrator 9 converts electrical energy into high-frequency mechanical vibration, generating ultrasonic waves that propagate in the cleaning fluid. These ultrasonic waves form air bubbles in the liquid; these bubbles are compressed in the high-pressure phase and expanded in the low-pressure phase of the sound waves, eventually bursting. The strong shock waves and high-speed microjets released when the bubbles burst effectively penetrate the pores of the screen, peeling off the attached powder and achieving deep cleaning. In this embodiment, the ultrasonic vibrator 9 uses existing technology, and its frequency and power can be adjusted according to the screen material and the degree of contamination.

[0028] Spray tank 4 is used to assist in spraying operations and collect the spray liquid generated during the spraying process. The specific spraying structure is integrated into the auxiliary cleaning components, and its function is to rinse away the fine particles and cleaning agents remaining after ultrasonic cleaning, thereby improving the cleanliness. Its specific structure will be described below.

[0029] The drying tank 5 is used to assist in the drying operation and collect water droplets that fall during the drying process. The specific drying structure is integrated into the auxiliary cleaning component, which is used to accelerate the drying of the screen and prevent water stains from remaining. Its specific structure will be described below.

[0030] In other embodiments not shown, to accommodate space constraints or simplify the structure, the spray tank 4 and the drying tank 5 can be combined into a single multi-functional settling tank. Under this design, the spraying and drying periods must be rationally arranged to avoid mutual interference.

[0031] See you again Figure 1The auxiliary cleaning components include a support truss 10 fixedly connected to the top of the settling platform 1 and a cleaning basket drive mechanism 11 connected to the support truss 10. The output end of the cleaning basket drive mechanism 11 is fixedly connected to a hanger 12 for suspending the screen cleaning basket 2. Specifically, the hanger 12 includes a horizontally arranged suspension plate 121, with heavy-duty chains 122 fixedly connected to the four corners of the bottom end of the suspension plate 121. These heavy-duty chains 122 connect to the lifting rings 23 at the top of the screen cleaning basket 2, thereby driving the screen cleaning basket 2 to move in the X, Y, and Z directions, achieving automated transfer. The cleaning basket drive mechanism 11 adopts a linear drive structure in the prior art, such as a synchronous belt drive structure, a gear and rack drive structure, or a ball screw drive structure, etc. The specific structure will not be described in detail in this embodiment.

[0032] See Figure 3 The suspension plate 121 integrates a spray structure. Specifically, the spray structure includes shower heads 13 fixedly embedded in the suspension plate 121. In this embodiment, at least four sets of shower heads 13 are provided, corresponding to the four corners of the suspension plate 121, to cover a larger cleaning area and ensure uniform spraying without dead angles. The top of the shower heads 13 is provided with interconnected water pipes 14, which are connected to an external water source. A booster pump and valve control structure can be added to the water source to adjust water pressure and flow. After the ultrasonic cleaning operation is completed, the cleaning basket drive mechanism 11 moves the screen cleaning basket 2 above the spray tank 4, at which point the spray structure is activated for spray rinsing. It is understood that in this embodiment, the water pipe 14 should be a flexible hose to accommodate the movement of the hanger 12.

[0033] In a preferred embodiment, to prevent liquid from splashing into adjacent settling tanks during spraying operations, a partition 15 is also connected between each settling tank, combined with... Figure 4 In this embodiment, the partition 15 adopts a telescopic structure to prevent interference with the movement of the screen washing basket 2 between sedimentation tanks. For example, the partition 15 adopts an accordion-style protective cover 151 structure, which is automatically extended and retracted by a rolling motor 152 fixedly connected to its front end. Specifically, a support frame 153 is fixedly connected to the front end of the accordion-style protective cover 151, and a hub 154 is rotatably connected to the inner side of the support frame 153. The hub 154 is driven by a rolling motor 152 fixedly installed on the side of the support frame 153 and rolls in cooperation with a preset guide rail 155 at the bottom of the accordion-style protective cover 151. To enhance telescopic stability and balance, auxiliary wheels 156 are also connected to both ends of the support frame 153 via welded support plates.

[0034] The drying structure includes multiple sets of dryers 16 fixedly connected to the support truss 10, which are positioned above the drying tank 5, and rapidly dry the sprayed screen by jetting hot air.

[0035] In practical applications, workers use forklifts to place the screen cleaning basket 2, which contains the screens to be cleaned, in the designated area of ​​the settling platform 1. Then, workers attach the lifting ring 23 of the screen cleaning basket 2 to the chain of the hanger 12 for gradual cleaning. The cleaning process includes ultrasonic cleaning, spray cleaning, and drying and blowing in sequence. After the entire process is completed, workers use forklifts to transfer the clean screens back to the production line for rapid recycling.

[0036] The screen cleaning device provided in this embodiment achieves automatic movement of the screen cleaning basket 2 between multiple processes through the cooperation of the supporting truss 10, the cleaning basket driving mechanism 11, and the hanger 12. The entire cleaning process is completed within a relatively closed system formed by the settling platform 1 and the settling tank. This not only enables batch automated processing of multiple sets of screens, significantly improving cleaning efficiency, but also improves the working environment and ensures the occupational health and safety of operators. At the same time, this embodiment directly integrates the spray structure onto the hanger 12 responsible for transfer, eliminating the complexity of separately installing and fixing the spray mechanism in the spray tank 4, and greatly optimizing space utilization.
