Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand filters, in particular to a sewage filtering device. Background Technique

[0002] In order to purify turbid water, sewage is usually filtered. Common ones include quartz sand filters. The quartz sand filter is a filter that forms a sand bed with homogeneous quartz sand of the same particle size as the filtering carrier for three-dimensional deep filtration. It is often used for primary filtration. Water with a higher turbidity is filtered through a certain thickness of granular or non-granular quartz sand, effectively intercepting and removing suspended solids, organic matter, colloidal particles, microorganisms, chlorine, odor and some heavy metal ions in the water. It has a strong ability to intercept dirt, and is suitable for deep well water filtration, agricultural water treatment, pre-treatment of various water treatment processes, etc. It can be used in various places such as factories, rural areas, hotels, schools, horticultural farms, water plants, etc. Among all filters, the quartz sand filter is the most effective in treating organic and inorganic impurities in water. This filter has a strong ability to filter out and retain impurities and can supply water continuously.

[0003] Nowadays, during the use of quartz sand filters, in the filtration of water sources with a large amount of organic matter, the sand bed often becomes caked, resulting in low filtration efficiency. Moreover, when the caking is serious, bacteria are likely to grow in the organic caking area, polluting the water source. At this time, it is often necessary to replace the sand bed for maintenance. However, the existing quartz sand filter tank is only provided with one discharge port and cannot quickly complete the replacement of the sand bed. In related technologies, a quick-release structure is set up to achieve the quick replacement of the sand bed, solving the problem that it takes a long time to replace the sand bed in the original quartz sand filter. However, it is found in actual use that due to the small distance between several layers of sand beds, it is inconvenient to replace and clean the middle sand bed when cleaning the sand bed, affecting the practicability.

[0034] The working principle of the quartz sand filter is to filter water with a relatively high turbidity through a certain thickness of granular or non-granular quartz sand, effectively intercepting and removing suspended solids, organic matter, colloidal particles, microorganisms, chlorine, odor, and some heavy metal ions, etc. It has a strong ability to intercept dirt.

[0035] In the related art, for a quartz sand filter that can quickly replace the sand bed, when replacing the sand bed, it does not have a good function of replacing the middle sand bed. During use, the middle sand bed cannot be quickly and conveniently replaced, which has certain limitations.

[0036] To solve the problems in the related art to a certain extent, an embodiment of the present application provides a sewage filtration device. When the middle sand bed needs to be replaced, first close the water inlet pipe 12, then completely open the outer shell baffle 21 through the hinge. After observing the sand bed to be replaced, start the motor inside the driving device 22. Drive the gear inside the driving device 22 to rotate, drive the slider 23 with a rack at the bottom to move horizontally, and push the filter media bearing platform 25 out of the quartz sand filter along the trough 24. Then open the first plate 28 and push the baffle 27 along the first rotating shaft 26 to complete the disassembly of the sand bed of one unit. After the filter media bearing platform 25 is rinsed and the baffle 27 is reset and the first plate 28 is fixed, pour the sand bed to be replaced into the filter media bearing platform 25. Start the driving device 22 to drive the slider 23 to fix the filter media bearing platform 25 in place along the trough 24 to complete the replacement task of the sand bed. This solves the problem that the middle sand bed cannot be replaced quickly and conveniently.

[0037] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0038] Combined with Figures 1 - 5 , an embodiment of the present application provides a sewage filtration device, including a main body assembly 1; the main body assembly 1 includes: an outer shell main body 11, with a water inlet pipe 12 fixedly connected to its top; a water collector 13, arranged inside the outer shell main body 11; a water outlet pipe 14, fixedly connected to the bottom of the outer shell main body 11; characterized in that: a moving assembly 2 is arranged inside the outer shell main body 11, and the moving assembly 2 includes: an outer shell baffle 21, rotatably connected to the outside of the outer shell main body 11; a driving device 22, arranged outside the outer shell main body 11 and there are two of them; a slider 23, slidably connected inside the driving device 22; a trough 24, opened inside the outer shell main body 11; a filter media bearing platform 25, slidably connected inside the trough 24 and fixedly connected to the slider 23; a first rotating shaft 26, rotatably connected inside the filter media bearing platform 25; a baffle 27, fixedly connected to the outside of the first rotating shaft 26 and rotatably connected to the filter media bearing platform 25 through the first rotating shaft 26; a first plate 28, fixedly connected to the outside of the filter media bearing platform 25.

[0039] When the utility model is in use, first move the outer shell main body 11 to a designated position, and then start the machine. The sewage to be filtered flows into the quartz sand filter from the water inlet pipe 12. After that, the sewage to be filtered is sprinkled on the filter sand bed through the water distributor installed inside the outer shell main body 11. After being filtered by a certain thickness of granular or non-granular quartz sand, the suspended solids, organic matters, colloidal particles, microorganisms, chlorine, odor and some heavy metal ions in the water are effectively intercepted and removed. Then, the filtered water passes through the water collector 13 at the bottom of the structure, converges together and flows out from the water outlet pipe 14 to the next filtration step. When filtering some water sources with a large organic matter content, the sand bed is often compacted, resulting in low filtration efficiency. Moreover, when the compaction is serious, bacteria are likely to grow at the organic matter compaction part, polluting the water source. At this time, it is often necessary to replace the sand bed for maintenance. First, close the water inlet pipe 12, and then completely open the outer shell baffle 21 through the hinge. After observing the sand bed to be replaced, start the motor inside the driving device 22. The motor drives the gear inside the driving device 22 to rotate, driving the slider 23 with a rack at the bottom to move horizontally, and pushing the filter media bearing platform 25 out of the quartz sand filter along the groove body 24. Then, open the first plate 28, and push the baffle 27 along the rotating shaft 26 to complete the disassembly of the sand bed. Subsequently, after flushing the filter media bearing platform 25 and resetting the baffle 27 and fixing the first plate 28, pour the sand bed to be replaced into the filter media bearing platform 25. Start the driving device 22 to drive the slider 23 to fix the filter media bearing platform 25 in place along the groove body 24 to complete the replacement task of the sand bed. After the replacement is completed, if other sand beds need to be replaced, repeat the above operation steps to complete.

[0040] In some embodiments, it is characterized in that: the moving component 2 further includes: a sealing rubber strip 29, which is bonded to one side of the outer shell baffle 21. By setting the sealing rubber strip 29, the sealing performance of the outer shell baffle 21 is better when it is connected to the outer shell main body 11, preventing water from seeping out of the equipment during normal operation.

[0041] In some embodiments, it is characterized in that: a rotating assembly 3 is arranged inside the filter media bearing platform 25, and the rotating assembly 3 includes: a second plate body 31 fixedly connected inside the baffle 27; a second rotating shaft 33 rotatably connected inside the second plate body 31; a third plate body 32 fixedly connected to the outside of the second rotating shaft 33 and rotatably connected to the second plate body 31 through the second rotating shaft 33; a fourth plate body 34 fixedly connected below the third plate body 32; a fifth plate body 35 fixedly connected below the second plate body 31, and the fifth plate body 35 is connected to the fourth plate body 34 through a bolt 36. After the baffle 27 finishes rotating, there is still part of the sand bed remaining inside the baffle 27. First, pull out the bolt 36 from the fourth plate body 34 and the fifth plate body 35, and then the third plate body 32 rotates along the second rotating shaft 33. The third plate body 32 changes from being in the same plane as the second plate body 31 to being perpendicular to the second plate body 31, so that the remaining part of the sand bed inside the baffle 27 can be completely shaken out. When the sand bed is completely cleaned, rotate the third plate body 32 along the second rotating shaft 33 to align the third plate body 32 with the second plate body 31, and then insert the bolt 36 into the hole in the middle of the fourth plate body 34 and the fifth plate body 35, and the restoration of the baffle 27 can be completed.

[0042] In some embodiments, it is characterized in that: a limiter is arranged inside the bolt 36. By providing the bolt 36 with a limiter inside, when installing the bolt 36, it only needs to align with the hole in the middle of the fourth plate body 34 and the fifth plate body 35, insert the bolt 36, and then rotate the bolt 36. When a click sound is heard, it means that the limiter has been snapped into the slot, and the installation can be completed. When disassembly is required, just rotate the bolt 36 to pull out the bolt 36 to complete the disassembly, which reduces the complexity of installation and disassembly while taking into account the fixation.

[0043] In some embodiments, it is characterized in that: the fourth plate body 34, the fifth plate body 35 and the bolt 36 form a group, and multiple groups are provided. By providing multiple groups, the supporting force between the second plate body 31 and the third plate body 32 is increased, and the stability of the structure is improved.

[0044] In some embodiments, it is characterized in that: the second rotating shaft 33 is arranged on one side of the second plate body 31. By arranging the second rotating shaft on one side of the second plate body 31, when all the bolts 36 are pulled out, the third plate body 32 will quickly fall downward under the action of gravity, shaking off all the remaining sand bed on the filter screen, reducing the workload during cleaning.

[0045] In some embodiments, it is characterized in that: the height of the tank body 24 is equal to the height of the filter media bearing platform 25. This enables the filter media bearing platform 25 to completely slide into the tank body 24 during fixation, improving the stability of the structure.

[0046] In some embodiments, it is characterized in that: a wing nut 4 is provided on the first plate body 28, and the first plate body 28 is connected through the wing nut 4. By providing the wing nut 4, when disassembling, only the protruding part of the wing nut 4 needs to be screwed by hand, so as to achieve the rapid disassembly of the first plate body 28 without tools.

[0047] In the description of this specification, the descriptions referring to the terms "one embodiment", "some embodiments", "example", "specific example", "some examples", etc. mean that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine the different embodiments or examples described in this specification.

[0048] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0049] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
