Description

Technical Field

[0001] This utility model relates to the field of sewage treatment devices, and in particular to a decentralized rural domestic sewage land infiltration treatment device. Background Technology

[0002] With the rapid development of my country's rural economy and the continuous improvement of residents' living standards, the discharge of rural domestic sewage has increased significantly, and its composition has become increasingly complex, including various pollutants such as organic matter, nitrogen and phosphorus nutrients, and suspended solids. Traditional centralized sewage treatment models are difficult to effectively promote and apply in rural areas due to reasons such as the dispersed population in rural areas, high pipeline construction costs, and difficulties in operation and maintenance.

[0003] Against this backdrop, decentralized wastewater treatment technology has become an effective way to solve rural domestic sewage problems due to its flexible construction, low operating costs, and simple maintenance. However, traditional land infiltration treatment devices still have obvious shortcomings in practical applications.

[0004] First, suspended solids in wastewater tend to accumulate on the surface of the filter layer, forming a filter cake layer, which leads to a decrease in permeability and a reduction in treatment efficiency. Second, traditional devices often use fixed filtration structures, which make the filter layer prone to caking and difficult to ensure filtration effectiveness.

[0005] Therefore, a decentralized rural domestic sewage land infiltration treatment device is proposed to solve the above problems. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a decentralized rural domestic sewage land infiltration treatment device, which aims to improve the problem that the filter layer is prone to clogging in the existing technology, making it difficult to maintain a stable filtration effect.

The output shaft of the motor is fixedly connected to a rotating shaft. A positioning rod is fixedly connected to the outer wall of the rotating shaft. An arc-shaped groove is formed on the outer wall of the positioning rod. A sliding plate is slidably connected to the inner wall of the right side of the treatment chamber. A round block is fixedly connected to the inner wall of the sliding plate. An annular plate is provided at the left end of the round block. An annular groove is formed on the right surface of the annular plate.

[0009] The percolation mechanism further includes a filter assembly, which includes a connecting ring fixedly connected to the inner surface of the annular plate. The top end of the connecting ring is fixedly mounted with a filter plate by bolts.

[0012] As a further description of the above technical solution:

[0013] The replacement assembly includes a slot located on the left surface of the processing compartment. A plug is inserted into the inner wall of the slot, and a sealing ring is fixedly connected to the left surface of the plug.

[0014] As a further description of the above technical solution:

[0015] The bottom of the inner wall of the processing chamber is designed to slope downwards from right to left, and the rotating shaft passes through and is rotatably connected to the lower surface of the processing chamber.

[0016] As a further description of the above technical solution:

[0017] The arc-shaped groove is designed as a wave shape with closed ends, and the arc-shaped groove is uniformly distributed in a ring on the outer wall of the positioning rod. The circular block is slidably connected to the inner wall of the arc-shaped groove.

[0024] This utility model has the following beneficial effects:

[0025] 1. In this utility model, the rotating shaft is driven by a motor, which causes the arc groove of the positioning rod to cooperate with the round block to drive the slide plate to move longitudinally back and forth, thereby causing the filter plate to fluctuate up and down.

[0035] 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.

[0036] Reference Figures 1-3 One embodiment of this utility model is a decentralized rural domestic sewage land infiltration treatment device, which includes a treatment chamber 1 for rural domestic sewage infiltration treatment. The lower section of the left surface of the treatment chamber 1 is connected to an outlet pipe 2 for discharging water that has been preliminarily filtered. The left end of the treatment chamber 1 is provided with a replacement component to facilitate the disassembly and assembly of the filter plate 42. The interior of the treatment chamber 1 is provided with an infiltration mechanism for infiltrating rural domestic sewage, and the infiltration mechanism can prevent impurities from accumulating and clogging.

[0037] Reference Figures 3-5 The percolation mechanism includes an anti-clogging component to prevent impurities from accumulating and forming a filter cake layer. The anti-clogging component includes a motor 31. The motor 31 is existing technology and can be implemented by those skilled in the art. As it is existing technology, it will not be described in detail in this case. The motor 31 is located on the lower surface of the treatment chamber 1. The output shaft of the motor 31 is fixedly connected to a rotating shaft 32. After the motor 31 is started, it can drive the rotating shaft 32 to rotate. A positioning rod 33 is fixedly connected to the outer wall of the rotating shaft 32. The rotating shaft 32 and the positioning rod 33 will rotate synchronously. An arc-shaped groove 34 is opened on the outer wall of the positioning rod 33. A sliding plate 35 is slidably connected to the inner wall of the right side of the treatment chamber 1. A round block 36 is fixedly connected to the inner wall of the sliding plate 35. The arc-shaped groove 34 and the round block 36 fit together. An annular plate 37 is provided at the left end of the round block 36. An annular groove 38 is opened on the right surface of the annular plate 37. The left end of the sliding plate 35 fits together with the annular groove 38.

[0038] Reference Figures 3-5 The bottom of the inner wall of the treatment chamber 1 is designed to slope downwards from right to left, allowing water to flow along the slope. The lowest point of the slope is aligned with the outlet pipe 2, and the water that has been preliminarily filtered can be discharged from the outlet pipe 2 to the subsequent filtration device or the ground. The rotating shaft 32 passes through and is rotatably connected to the lower surface of the treatment chamber 1. The arc-shaped groove 34 is designed to be wavy with both ends closed, and the arc-shaped groove 34 is evenly distributed in a ring on the outer wall of the positioning rod 33. The round block 36 is slidably connected to the inner wall of the arc-shaped groove 34. When the arc-shaped groove 34 rotates with the positioning rod 33, it will squeeze the round block 36, which will then drive the round block 36 and the slide plate 35 to move longitudinally back and forth. The left end of the slide plate 35 is slidably connected to the inner wall of the annular groove 38, which is opened in a semi-circular shape.

[0039] Reference Figure 3 , Figure 4 , Figure 6The percolation mechanism also includes a filter assembly, which includes a connecting ring 41. The connecting ring 41 is fixedly connected to the inner surface of the annular plate 37. A filter plate 42 is fixedly installed on the top of the connecting ring 41 by bolts. The filter plate 42 is detachable. Different types of filter layers are filled in the filter plate 42 from top to bottom to achieve multi-layer filtration. When the filter plate 42 moves up and down and rotates, the filter layers can be shaken to ensure the filtration effect and avoid clogging. The filter assembly also includes a fixing ring 43, which is fixedly connected to the inner surface of the treatment chamber 1. A groove 44 is provided on the inner wall of the left side of the fixing ring 43. A protrusion 45 is fixedly connected to the left surface of the annular plate 37. The protrusion 45 and the groove 44 fit together.

[0040] Reference Figure 3 , Figure 4 , Figure 6 The slide 44 is wavy and semi-circular. The protrusion 45 is slidably connected to the inner wall of the slide 44. When the protrusion 45 moves longitudinally back and forth with the annular plate 37, it will squeeze the inner wall of the slide 44, and the annular plate 37 will rotate. The slide plate 35 passes through and is slidably connected to the right surface of the fixed ring 43. The slide plate 35 moves longitudinally back and forth.

[0041] Reference Figures 1-3 The replacement component includes a slot 61, which is located on the left surface of the processing chamber 1. A plug 62 is inserted into the inner wall of the slot 61. A sealing ring 63 is fixedly connected to the left surface of the plug 62. The upper and lower ends of the right surface of the plug 62 are set as bevels to facilitate the insertion of the plug 62 and the slot 61. The plug 62 is fixedly installed to the processing chamber 1 by bolts to ensure the stability of the fixation. Both the plug 62 and the processing chamber 1 are provided with mounting holes to facilitate the use of bolts to fix the plug 62. The sealing ring 63 and the processing chamber 1 are interference fit to maintain a seal and prevent leakage.

[0042] Working principle: Rural domestic sewage first enters treatment chamber 1 and is filtered through filter plate 42 in the filtration assembly. Filter plate 42 is filled with multiple layers of different types of filter media (such as sand, activated carbon, etc.), which can effectively intercept suspended solids, organic matter and other pollutants in the sewage.

[0043] Then, the motor 31 is started, which drives the rotating shaft 32 and the positioning rod 33 to rotate synchronously. The wavy arc groove 34 on the outer wall of the positioning rod 33 cooperates with the round block 36 to push the slide plate 35 to move longitudinally back and forth along the inner wall of the treatment chamber 1. The slide plate 35 drives the annular plate 37 to fluctuate up and down through the annular groove 38. At the same time, the protrusion 45 cooperates with the wavy sliding groove 44 on the fixed ring 43 to make the annular plate 37 rotate. The fluctuation and rotation of the annular plate 37 drive the filter plate 42 to shake, preventing the filter material from caking or clogging and ensuring filtration efficiency.

[0044] Wastewater is filtered step by step through the multi-layer filter media of filter plate 42 to remove pollutants. The shaking of filter plate 42 keeps the filter media loose, preventing impurities from accumulating and forming a filter cake layer. At the same time, it promotes full contact between wastewater and filter media, improving the treatment effect.

[0045] The filtered water flows along the inclined surface at the bottom of the treatment chamber 1 to the outlet pipe 2, and is eventually discharged to the land or subsequent treatment unit. When the filter plate 42 needs to be replaced or cleaned, the bolts on the insert 62 are removed, and the insert 62 and sealing ring 63 are taken out. The left side of the treatment chamber 1 can then be opened for maintenance. The filter plate 42 is fixed by the bolts of the connecting ring 41, which makes disassembly and assembly convenient and facilitates the replacement of filter media or cleaning.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
