Description

Technical Field

[0001] This invention relates to the field of wastewater reuse technology, specifically to an ecological reuse device for domestic wastewater based on soil infiltration. Background Technology

[0002] With the acceleration of urbanization and the improvement of residents' living standards, the discharge of domestic sewage continues to increase. If not properly treated, it can easily lead to environmental problems such as eutrophication of water bodies and soil pollution, while exacerbating the contradiction of water shortage. Traditional domestic sewage treatment technologies, such as the activated sludge process, have problems such as high infrastructure costs, high energy consumption, and the need for professional operation and maintenance, making it difficult to be widely used in small and medium-sized towns and rural areas. Moreover, the treated sewage is mostly discharged directly, without fully exploring its resource value.

[0003] Common domestic sewage ecological reuse devices have fixed and unadjustable infiltration layers, and sewage can only be treated in a single soil layer. This can easily lead to fluctuations in purification effect due to the adsorption saturation of that soil layer, and it also cannot allow multiple soil layers to obtain nutrients evenly, resulting in uneven soil improvement. Furthermore, the resource utilization efficiency is low, and water resources are mostly reused or discharged in a crude manner, rather than being directed to meet the water needs of each soil layer, resulting in serious waste of supporting resources. Therefore, we propose a domestic sewage ecological reuse device based on soil infiltration. Summary of the Invention

The outer walls of the three rotating rods are connected to the upper lifting plate, and the three lifting control frames are connected by a linkage frame.

[0009] As a further embodiment of the present invention: the outer wall of the small wetland box is connected to a layer stabilizing plate for fixing the position of the layer fixing plate. The upper end of the layer stabilizing plate is provided with a support groove. The rear wall of the support groove is rotatably connected to a lifting rotating shaft. The outer wall of the lifting rotating shaft is connected to the layer fixing plate. The layer fixing plate is connected to the side wall of the support groove through a return spring, and the return spring is sleeved on the outside of the lifting rotating shaft.

[0010] As a further aspect of the present invention: the outer wall of the small wetland box is provided with a release groove, the bottom wall of the release groove is connected to a lifting shaft, the inside of the release groove is slidably connected to a release plate for pushing the layer fixing plate to rotate, and the lower end of the release plate is provided with a hollow hole, the inner wall of the hollow hole is slidably connected to the outer wall of the lifting shaft.

[0011] As a further embodiment of the present invention: a control shaft is connected to the side of the release plate near the layer fixing plate, and a translation groove is provided on the side of the layer fixing plate near the release plate. The outer wall of the control shaft is slidably connected to the inner wall of the translation groove.

[0012] As a further aspect of the present invention: a translational slide groove is provided on the side of the lifting control frame near the small wetland box, a movable slider is slidably connected inside the translational slide groove, and a lead screw is rotatably connected to the left side wall of the translational slide groove for driving the movable slider to move by being helically connected to it.

[0013] As a further aspect of the present invention: the outer wall of the small wetland box is provided with a movable slide groove, and the movable slider extends into the interior of the movable slide groove from the side away from the lifting control frame and is slidably connected to the inner wall of the movable slide groove. The outer wall of the small wetland box is connected to a mounting frame, and the upper end of the mounting frame is connected to a lifting pump. The output end of the lifting pump is connected to the lower end of the lifting control frame.

[0014] Compared with the prior art, the beneficial effects of the present invention by adopting the above technical solution are as follows:

[0015] 1. This invention utilizes the principle of soil infiltration to purify wastewater through soil and microorganisms within a small wetland tank, achieving a high standard of effluent quality. By operating the lifting plate on the outside of the small wetland tank, the infiltration layer control plate can be moved up and down, allowing wastewater to be distributed to different soil layers as needed, thereby improving soil fertility. The layer fixing plate can fix the position of the lifting plate after the infiltration layer control plate is adjusted to the target height, ensuring that the infiltration layer control plate is stable at the set height. It can be discharged to a designated soil layer as needed, realizing the reuse of water resources and improving the efficiency of water resource utilization.

[0016] 2. The lifting control frame of this invention achieves synchronous movement through the linkage frame. With the transmission structure of the anti-reverse groove and the rotating rod, it ensures that the lifting plate is evenly stressed and avoids tilting or jamming of the percolation layer control plate during the lifting process. The anti-reverse groove design of the lifting control frame, combined with the rotation characteristics of the rotating rod, can effectively prevent the lifting plate from sliding down due to sewage pressure or its own weight when there is no power drive, thus avoiding accidental changes in the percolation layer. The connecting frame passes through the reuse transfer box and the small wetland box through the lifting slide, organically combining the internal percolation layer control plate with the external lifting control mechanism, realizing precise linkage between internal and external actions.

[0017] 3. This invention drives the layer fixing plate to rotate and disengage from the connecting frame through a simple upward pull action, quickly releasing the lock on the percolation layer control plate and allowing it to smoothly descend to the bottom of the recycling transfer box. Operators can precisely adjust the position of the components according to actual needs, avoiding structural damage caused by excessive operation and enhancing the reliability of the device operation. The cooperation between the trough structure such as the release chute, the translation chute, and the moving chute and the corresponding shaft components forms a complete locking-release-avoidance linkage system, enabling the lifting and lowering adjustment of the percolation layer control plate to form a closed-loop operation from rising to locking to falling to resetting.

[0018] Other advantages, objectives and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be learned from the practice of the invention.

[0028] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0029] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Example 1

[0031] This invention relates to an ecological reuse device for domestic sewage based on soil infiltration. In densely populated residential areas of small and medium-sized towns or rural villages, domestic sewage is often directly discharged into surrounding ditches or soil, which easily leads to eutrophication of water bodies and soil pollution. At the same time, local crop irrigation and green space maintenance face the contradiction of water resource shortage. Traditional sewage treatment technologies such as activated sludge process are difficult to promote in these areas due to high infrastructure costs and the need for professional operation and maintenance personnel. As a result, the value of sewage resources is not fully explored, which pollutes the environment and wastes water resources. At this time, an ecological reuse device for domestic sewage based on soil infiltration can be installed around densely populated residential areas or on the edge of villages. After collecting the domestic sewage discharged from residents' homes, it is transported to a small wetland tank through the reuse transfer pipe of the device.

[0032] Therefore, in order to effectively solve the above problems, this application proposes a device for the ecological reuse of domestic sewage based on soil infiltration, as shown in the attached drawings of the specification. Figure 1-8 As shown, the device includes a reuse device 1, a small wetland tank 2 for reusing wastewater installed on one side of the reuse device 1, a reuse transfer pipe 11 for transferring wastewater into the small wetland tank 2 installed inside the reuse device 1, a percolation pipe 21 for discharging wastewater installed inside the small wetland tank 2, a reuse transfer box 22 for transferring wastewater installed inside the small wetland tank 2, and a percolation layer control plate 23 for controlling the discharge of wastewater from different percolation pipes 21 installed inside the reuse transfer box 22. A lifting plate 24 for controlling the height of the percolation layer control plate 23 is installed on the outside of the small wetland tank 2, and a layer fixing plate 25 for stabilizing the height position of the lifting plate 24 is installed inside the small wetland tank 2.

[0033] The interior of the small wetland tank 2 is arranged from bottom to top as a layer of large gravel, a layer of small gravel, a layer of sand, and a layer of soil.

[0034] The reuse device 1 first collects the wastewater to be treated, and then through the conveying function of the reuse transfer pipe 11, the wastewater is directionally transferred to the small wetland tank 2 on one side to provide water for the subsequent purification steps. After the wastewater enters the small wetland tank 2, it first flows into the reuse transfer tank 22. The transfer tank plays the role of temporarily storing and buffering the wastewater to prevent the wastewater from directly impacting the internal structure of the wetland.

[0035] If it is necessary to control the infiltration level of wastewater, the lifting plate 24 on the outside of the small wetland tank 2 can be operated. The lifting plate 24 will drive the infiltration level control plate 23 inside the transfer tank to move up and down, changing the outflow height of wastewater in the transfer tank. When the infiltration level control plate 23 is adjusted to the target height, the level fixing plate 25 will fix the position of the lifting plate 24 to ensure that the infiltration level control plate 23 is stable at the set height, thereby controlling the depth of wastewater flowing from the reuse transfer tank 22 into the small wetland tank 2.

[0036] Wastewater that has undergone tiered control will enter the interior of the small wetland tank 2 as needed. The purified wastewater will then leak out through the infiltration pipe 21 inside the small wetland tank 2. The infiltration pipe 21 can guide the purified water to the designated tier.

[0037] Example 2

[0038] The top of the recycling transfer box 22 is equipped with a sealing plate 31 for sealing the recycling transfer box 22, and the upper end of the percolation layer control plate 23 is connected to a connecting frame 3, the upper end of the connecting frame 3 extending to the outside of the recycling transfer box 22.

[0039] A lifting slide 42 is provided on one side of the small wetland box 2, and the connecting frame 3 extends to the outside of the small wetland box 2 through the lifting slide 42. Three lifting control frames 4 for driving the upper lifting plate 24 to rise and fall are slidably connected to the outer wall of the small wetland box 2.

[0040] Each of the three lifting control frames 4 has an anti-reverse groove 41 on the side near the small wetland box 2, and the left end of each of the three anti-reverse grooves 41 is rotatably connected to a rotating rod. The outer wall of each of the three rotating rods is connected to the upper lifting plate 24, and the three lifting control frames 4 are connected by a linkage frame 46.

[0041] The outer wall of the small wetland box 2 is connected to a layer stabilizing plate 43 for fixing the position of the layer fixing plate 25. The upper end of the layer stabilizing plate 43 is provided with a support groove. The rear wall of the support groove is rotatably connected to a lifting rotating shaft 44. The outer wall of the lifting rotating shaft 44 is connected to the layer fixing plate 25. The layer fixing plate 25 is connected to the side wall of the support groove through a return spring 45, and the return spring 45 is sleeved on the outside of the lifting rotating shaft 44.

[0042] Start the lifting pump and use the lifting pump to push the lifting control frame 4 to move upward. At this time, the lifting control frame 4 will push the upper lifting plate 24 to move upward, which in turn pushes the connecting frame 3 on the upper lifting plate 24 and the infiltration layer control plate 23 connected to the connecting frame 3 to move upward, so that the connecting frame 3 is placed on the layer fixing plate 25. The upward movement of the infiltration layer control plate 23 will control the infiltration pipe 21 that sewage can enter, thereby controlling the sewage to seep into different layers of the soil.

[0043] When the lifting pump retracts, the lower end of the upper lifting plate 24 will contact the connecting frame 3. At this time, the connecting frame 3 will push the upper lifting plate 24 to rotate, thereby moving the connecting frame 3 below the upper lifting plate 24, which facilitates the lifting operation of the connecting frame 3 from the lower side.

[0044] Example 3

[0045] The outer wall of the small wetland box 2 is provided with a release groove 5. The bottom wall of the release groove 5 is connected to a lifting shaft. The release plate 51 for pushing the layer fixing plate 25 to rotate is slidably connected inside the release groove 5. The lower end of the release plate 51 is provided with a hollow hole. The inner wall of the hollow hole is slidably connected to the outer wall of the lifting shaft.

[0046] A control shaft is connected to the side of the release plate 51 near the layer fixing plate 25. A translation groove 52 is provided on the side of the layer fixing plate 25 near the release plate 51. The outer wall of the control shaft is slidably connected to the inner wall of the translation groove 52.

[0047] The lifting control frame 4 has a translational slide 61 on the side near the small wetland box 2. The translational slide 61 is slidably connected to the inside of the translational slide 61, and the left side wall of the translational slide 61 is rotatably connected to a lead screw 62 for spirally connecting with the moving slider 63 to drive the moving slider 63 to move.

[0048] The outer wall of the small wetland box 2 is provided with a movable slide 64, and the movable slider 63 extends into the interior of the movable slide 64 on the side away from the lifting control frame 4 and is slidably connected to the inner wall of the movable slide 64. The outer wall of the small wetland box 2 is connected to a mounting frame, and the upper end of the mounting frame is connected to a lifting pump. The output end of the lifting pump is connected to the lower end of the lifting control frame 4.

[0049] When it is necessary to move the percolation layer control plate 23 to the bottom of the reuse transfer box 22, pull the release plate 51 to move it upward. At this time, the release plate 51 will pull the lifting shaft upward, which will then cooperate with the release slide 5 to pull the layer fixing plate 25 to rotate. The rotation of the layer fixing plate 25 will move it to a position where it does not contact the connecting frame 3. At this time, the connecting frame 3 and the percolation layer control plate 23 can be controlled to move downward.

[0050] At the same time, the lead screw 62 is rotated, and the rotation of the lead screw 62 causes the moving slider 63 to move horizontally. However, since the left and right sides of the moving slider 63 are fixed, the lifting control frame 4 will be driven to move horizontally until the lifting plate 24 moves to a position where it will not contact the connecting frame 3. At this time, the height of the connecting frame 3 and the percolation layer control plate 23 can be controlled to decrease.
