Technical Field
[0001] This utility model relates to the technical field of flushing and drainage devices, and in particular to a flushing and drainage anti-clogging device for lump coal product warehouses. Background Technology
[0002] In the field of coal washing and processing, lump coal product bins are key nodes for storage and transfer. The stable operation of their washing system directly affects production efficiency and equipment safety. Traditional washing and drainage treatment devices generally use fixed screen plates as the core filtration structure. This structure intercepts impurities such as coal slurry and broken coal in the washing water through metal screen plates with fixed apertures, preventing large particles from entering the drainage pipes and causing blockages. When the flushing and drainage device is in use, traditional devices generally use fixed screen plates and grates as the flushing and drainage filtration structure. The surface of the screen plate and grate usually has multiple sets of channels to achieve the screening function and intercept large particles of impurities in the flushing water. However, when the channels are blocked due to the accumulation of impurities, the existing technical solution requires the screen plate and grate to be disassembled for cleaning. This operation mode has a significant efficiency bottleneck in the case of frequent maintenance. The disassembly process involves multiple steps such as loosening bolts and repositioning the grate. Each cleaning takes a long time and requires professional maintenance personnel and special tools, which leads to the extended downtime of the flushing system and directly affects the continuous operation efficiency of the lump coal bunker.
[0003] Therefore, to address the issue of inconvenience in improving operational efficiency during maintenance, a flushing and drainage anti-clogging device for lump coal product bins can be designed. When using this device, flushing water enters the collection tank through multiple sets of channels perforated on the surface of the screen grate. The screening function of these channels intercepts large particles of impurities. When the channels need cleaning due to impurity accumulation, the operator rotates the lifting mechanism, which drives multiple sets of top plates to rise. The top plates penetrate the bottom of the screen grate corresponding to the channel positions, pushing the impurities clogging the channels upwards. When the upper surface of the top plate touches the screen... When the upper surface of the grate is flush, impurities are fully exposed and can be directly swept away with tools such as brooms. After cleaning, the reverse rotation lifting mechanism drives multiple sets of top plates to descend, and the device returns to the filtration state. This device uses a mechanical lifting structure to push out impurities, and cleaning can be completed without disassembling the screen grate, significantly improving operational efficiency. In summary, this device achieves the dual functions of anti-clogging of the flushing drainage and rapid cleaning through structural optimization, effectively improving the operating efficiency and maintenance convenience of the lump coal product silo flushing system, and has significant technical practicality and economic value.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0016] Please see Figure 1 and Figure 3 This utility model provides an embodiment: a flushing and drainage anti-clogging device for lump coal product storage, including a screen grate 1, which is installed at the ground opening in a low-lying area. A water collection trough is provided at the ground opening in the low-lying area, and a stepped groove is provided on the inner wall of the water collection trough. The bottom of the screen grate 1 is mounted on the upper surface of the stepped groove. It also includes a lifting mechanism and a top plate 2. The lifting mechanism is provided at the bottom of the screen grate 1, and multiple sets of top plates 2 are provided on the upper surface of the lifting mechanism. Multiple sets of through grooves 3 are opened through the inside of the screen grate 1, and the multiple sets of top plates 2 correspond one-to-one with the multiple sets of through grooves 3.
[0017] Please see Figure 4 and Figure 5 The lifting mechanism includes a handwheel 4, a threaded rod 5, and a limiting ring 6. The threaded rod 5 is rotatably mounted on the inner wall of the center of the screen grate 1. The handwheel 4 is fixedly mounted on the upper end of the threaded rod 5, and the limiting ring 6 is fixedly mounted on the lower end of the threaded rod 5. When the operator rotates the handwheel 4 in the center of the screen grate 1, the handwheel 4 drives the threaded rod 5 to rotate on the inner wall of the screen grate 1. The limiting ring 6 at the lower end of the threaded rod 5 ensures the stability of the rotation. The lifting mechanism also includes a lifting frame 7. The lifting frame 7 is set below the screen grate 1. The inner wall of the lifting frame 7 is sleeved on the side wall of the threaded rod 5 and threadedly connected to the side wall of the threaded rod 5. The rotation of the threaded rod 5 drives the lifting frame 7, which is threadedly connected to it, to rise.
[0018] Please see Figure 4 and Figure 5Guide columns 8 are fixedly installed at the four corners of the bottom surface of the sieve grate 1. Limiting plates 9 are fixedly installed at the lower end of the guide columns 8. The inner walls of the four corners of the lifting frame 7 are fitted onto the side walls of the guide columns 8 and are slidably connected to the side walls of the guide columns 8. The rotation of the threaded rod 5 drives the lifting frame 7, which is threadedly connected to it, to rise vertically along the four sets of guide columns 8. The four corners of the lifting frame 7 are precisely guided by the sliding cooperation between the guide columns 8 and the limiting plates 9 to avoid deviation. Multiple sets of support rods 10 are fixedly installed on the upper surface of the lifting frame 7. The bottom surfaces of multiple sets of top plates 2 are fixedly connected to the upper ends of multiple sets of support rods 10 respectively. During the rise of the lifting frame 7, the multiple sets of support rods 10 drive the multiple sets of top plates 2 fixed at the top to move upward synchronously. The top plates 2 penetrate from the bottom of the sieve grate 1 to the corresponding position of the through groove 3, pushing the impurities blocked in the through groove 3 upward.
[0019] Please see Figure 2 and Figure 3 The screen grate 1 has countersunk holes 11 through all four sides of its inner wall, and threaded holes are opened on the bottom wall of the stepped groove. Multiple sets of threaded holes correspond one-to-one with multiple sets of countersunk holes 11. Countersunk studs 12 are installed through the countersunk holes 11 and are threadedly connected to the threaded holes. The device achieves basic positioning by fitting the screen grate 1 into the stepped groove of the water collection tank. The bottom of the screen grate 1 is mounted on the stepped groove, and a stable connection is achieved by using the countersunk studs 12 through the correspondence between the countersunk holes 11 and the threaded holes on the bottom wall of the stepped groove.
[0020] When using this flushing and drainage device, the working principle of the flushing and drainage anti-clogging device for lump coal product silos of this utility model is as follows: The device achieves basic positioning by fitting the screen plate grate 1 into the stepped groove of the water collection tank. The bottom surface of the screen plate grate 1 is mounted on the stepped groove, and a stable connection is achieved by using countersunk studs 12 through the correspondence between the countersunk hole 11 and the threaded hole on the bottom wall of the stepped groove.
[0021] When the flushing water in the chamber flows to the opening in the low-lying area, the water flows through the multiple sets of channels 3 opened on the surface of the screen plate grating 1 and enters the water collection tank. The screening function of the channels 3 can intercept large particles of impurities and prevent them from entering the water collection tank and clogging the subsequent pumping equipment.
[0022] When the channel 3 needs to be cleaned due to the accumulation of impurities, the operator rotates the handwheel 4 in the center of the screen grate 1. The handwheel 4 drives the threaded rod 5 to rotate on the inner wall of the screen grate 1. The limiting ring 6 at the lower end of the threaded rod 5 ensures the stability of the rotation. The rotation of the threaded rod 5 drives the lifting frame 7, which is connected to it by threads, to rise vertically along the four sets of guide columns 8. The four corners of the lifting frame 7 are precisely guided by the sliding cooperation between the guide columns 8 and the limiting plate 9 to avoid deviation.
[0023] During the lifting process of the lifting frame 7, multiple sets of support rods 10 drive multiple sets of top plates 2 fixed at the top to move upward synchronously. The top plates 2 pass through the corresponding slots 3 at the bottom of the screen grates 1, pushing the impurities blocked in the slots 3 upward. When the upper surface of the top plate 2 is flush with the upper surface of the screen grates 1, the impurities are fully exposed and can be directly cleaned and removed with brooms or other tools.
[0024] After cleaning is completed, the handwheel 4 is rotated in the opposite direction to reverse the threaded rod 5. The lifting frame 7 descends along the guide column 8 under the influence of gravity and the threaded drive. The top plate 2 then returns to the bottom of the through groove 3, and the device resumes the filtration state. This device achieves the removal of impurities through a mechanical lifting structure, and can complete the cleaning without disassembling the screen plate grate 1, which significantly improves the operating efficiency.
[0025] In summary, firstly, the filtration function of the screen grate 1 effectively intercepts large particles of impurities, preventing blockage of the water collection tank and subsequent equipment from the source, and ensuring the continuous and stable operation of the flushing system. Secondly, the linkage design between the lifting mechanism and the top plate 2 allows for precise lifting and lowering of the top plate 2 via the handwheel 4, enabling impurities in the channel 3 to be quickly ejected and exposed, making the cleaning process simple and efficient, avoiding the tedious steps of traditional grate disassembly and cleaning, and significantly shortening maintenance time. Thirdly, the sliding cooperation between the guide column 8 and the limiting plate 9 ensures the smooth operation of the lifting frame 7, preventing misalignment between the top plate 2 and the channel 3, and improving the reliability of the device. Finally, the concealed installation of the countersunk stud 12 ensures a stable connection of the screen grate 1 while preventing the stud from being exposed and affecting the cleaning operation. The overall structure is compact and highly practical. In conclusion, this device achieves the dual functions of anti-blockage of the flushing drainage and rapid cleaning through structural optimization, effectively improving the operating efficiency and maintenance convenience of the lump coal product bin flushing system, and has significant technical practicality and economic value.
[0026] Through the above steps, when using this flushing and drainage device, the flushing water in the silo enters the water collection tank through multiple sets of channels 3 that penetrate the surface of the screen grate 1. The screening function of the channels 3 can intercept large particles of impurities. When the channels 3 need to be cleaned due to the accumulation of impurities, the operator can rotate the lifting mechanism to drive multiple sets of top plates 2 to rise. The top plates 2 penetrate from the bottom of the screen grate 1 to the corresponding position of the channels 3, pushing the impurities blocking the channels 3 upward. When the upper surface of the top plate 2 is flush with the upper surface of the screen grate 1, the impurities are fully exposed. At this time, they can be directly swept away with brooms or other tools. After cleaning, the lifting mechanism is rotated in the opposite direction to drive multiple sets of top plates 2 to fall, and the device returns to the filtration state. This device achieves the removal of impurities through a mechanical lifting structure, and can complete the cleaning without disassembling the screen grate 1, significantly improving the operating efficiency.
