Description

Technical Field

[0001] The invention relates to the technical field of water treatment, in particular to rainwater garden recycling equipment with a flow self-adaptation function. Background Art

[0002] The rainwater garden reuse equipment is used to filter and collect rainwater, and then undergoes a series of filtration and purification to achieve the purpose of reuse. The reused rainwater can not only irrigate trees and wash roads, but also replenish groundwater resources, alleviating the problems of water shortage and ecological environment deterioration caused by urbanization.

[0003] However, the flow regulation modules of rainwater garden recycling systems currently available on the market are complex and require continuous power supply, resulting in high energy consumption and a high failure rate. Furthermore, the rainwater collection process generates a large number of bubbles, which, when burst, can cause cavitation in the recycling system's pipelines, thus shortening the overall service life of the recycling system. Therefore, a rainwater garden recycling system with flow adaptation is needed to address these issues. Summary of the Invention

[0004] The purpose of the present invention is to provide a rainwater garden recycling device with flow self-adaptation function to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] The reuse equipment includes a filter barrel, a connecting pipe and a water reservoir. The outlet of the filter barrel is connected to one end of the connecting pipe, and the other end of the connecting pipe is connected to the inlet of the water reservoir. A regulating pipe is provided at the inlet of the filter barrel, and the outlet end of the regulating pipe is connected to the inlet of the filter barrel. A garbage screening module, a bubble elimination module and a flow regulating module are provided in the regulating pipe. The garbage screening module is provided at the inlet of the regulating pipe, and the garbage screening module and the regulating pipe are rotatably connected. The flow regulating module is provided at the outlet of the regulating pipe, and the flow regulating module and the regulating pipe are slidably connected. The bubble elimination module is provided in the regulating pipe, and the bubble elimination module is located between the garbage screening module and the flow regulating module. The bubble elimination module and the flow regulating module are fixedly connected, and the bubble elimination module and the regulating pipe are slidably connected.

[0007] When it rains, large amounts of garbage will be mixed in the rainwater, and the garbage mixed with rainwater will enter from the entrance of the regulating pipe. The garbage screening module will screen out and collect the large amount of garbage from the regulating pipe, and then the rainwater will pass through the bubble elimination module, driving the bubble elimination module to converge the bubbles to the central axis of the regulating pipe, and then cooperate with the flow regulation module to eliminate most of the bubbles. When the rainwater flow becomes larger, the force of rainwater pushing the bubble elimination module and the flow regulation module will increase, and the flow regulation module will gradually open, so that the cross-sectional area of ​​the flow channel in the regulating pipe will increase, thereby increasing the flow rate of rainwater flowing into the filter barrel. After being filtered by the filter barrel, it will be collected by the reservoir, which improves the rainwater collection efficiency. At the same time, the force generated by the bubbles in the rainwater when they burst will also assist the regulation of the flow regulation module; when the rainwater flow becomes smaller, the bubble elimination module and the flow regulation module are pushed by less rainwater, and the bubble elimination module and the flow regulation module slide toward the entrance of the regulating pipe, and the cross-sectional area of ​​the flow channel in the regulating pipe is reduced, thereby realizing adaptive regulation of the flow.

[0008] Furthermore, diversion pipelines are provided on both sides of the regulating pipe in the horizontal direction, the inlets of the diversion pipelines on both sides are located between the garbage screening module and the bubble elimination module, and the outlets of the diversion pipelines on both sides are located between the bubble elimination module and the flow regulating module.

[0009] When the rainwater flow rate suddenly increases, the high-speed flowing rainwater will cause a large impact force on the bubble elimination module and the flow regulation module, thereby damaging the bubble elimination module and the flow regulation module, reducing the service life of the reuse equipment. By setting up a diversion pipeline, when the rainwater flow rate suddenly increases, the rainwater in the main channel of the regulation pipe will be diverted, reducing the impact force on the bubble elimination module and the flow regulation module, and improving the service life of the reuse equipment.

[0010] Furthermore, a trash bin, a filter plate and a filter tube are provided on one side of the regulating tube in the horizontal direction. The inlet of the trash bin is connected to the regulating tube. The inlet of the trash bin is located between the inlet of the regulating tube and the garbage screening module. The outlet of the trash bin is connected to one end of the filter tube. A filter plate is provided in one end of the filter tube. The filter plate and the filter tube are fixedly connected. The outlet of the trash bin is connected to the inlet of the filter barrel.

[0011] The large volume of garbage mixed in the rainwater is blocked by the garbage screening module and carried into the garbage bin by the water flow for collection. The rainwater in the garbage bin is then filtered through the filter plate and enters the filter barrel through the filter pipe for filtration. The filter pipe connecting the garbage bin and the filter barrel is set to effectively prevent rainwater from being collected in the garbage bin and then backflowing, bringing the garbage in the garbage bin back into the regulating pipe and clogging the regulating pipe.

[0012] Furthermore, the garbage screening module includes multiple rollers, which are vertically arranged and rotatably connected to the adjustment pipe. The closer the multiple rollers are to the entrance of the garbage bin, the farther they are from the entrance of the adjustment pipe. The entrance of the garbage bin is located between the roller closest to the entrance of the garbage bin and the entrance of the adjustment pipe.

[0013] Driven by rain, large amounts of garbage hit the drum. With the continuous impact of rain, large amounts of garbage continue to flow along the drum to the entrance of the trash bin and eventually enter the trash bin. The drum is rotatably connected to the regulating pipe to facilitate the flow of large amounts of garbage along the drum to the trash bin when it hits the drum.

[0014] Furthermore, the bubble elimination module includes a bubble slide, a bubble rotating ring and an impeller. The bubble slide is located between the inlet of the diversion pipeline and the flow regulating module. The bubble slide is fixedly connected to the flow regulating module. The bubble slide is slidingly connected to the regulating tube. The bubble rotating ring is rotatably connected to the bubble slide. The outer edge of the impeller is fixedly connected to the bubble rotating ring. The central axis of the impeller coincides with the rotation axis of the bubble rotating ring.

[0015] When rainwater flows through the impeller, it drives the impeller and the bubble ring to rotate. When the impeller rotates, the bubbles in the rainwater will converge toward the central axis of the regulating tube under the influence of centrifugal force, preventing the bubbles from bursting at the wall of the regulating tube, causing cavitation on the wall of the regulating tube, and greatly reducing the service life of the regulating tube.

[0016] Furthermore, the impeller includes a central wheel shaft and blades, one end of the blade is fixedly connected to the central wheel shaft, and the other end of the blade is fixedly connected to the bubble rotating ring. One side of the blade extends beyond the inlet end of the central wheel shaft, the inlet aperture of the central wheel shaft is larger than the outlet aperture, and the central axis of the central wheel shaft coincides with the rotation axis of the bubble rotating ring.

[0017] One side of the blade extends beyond the inlet end of the center wheel shaft, generating a vortex before the inlet of the center wheel shaft, causing the bubbles to converge to the central axis of the regulating tube in advance, and thus enter the center wheel shaft. The inlet aperture of the center wheel shaft is larger than the outlet aperture. The closer to the outlet of the center wheel shaft, the greater the water flow pressure. The tiny bubbles merge near the outlet of the center wheel shaft, which facilitates the subsequent collapse of the bubbles.

[0018] Furthermore, a shear rod is provided at the outlet of the central wheel shaft. The shear rod passes through the central wheel shaft in the radial direction of the central wheel shaft. The shear rod is fixedly connected to the central wheel shaft.

[0019] The shear rod is responsible for initially collapsing the bubbles merged at the outlet of the central wheel shaft, thereby improving the bubble collapse efficiency.

[0020] Furthermore, the flow regulating module includes a defoaming rod, a sliding base, a return spring, a connecting rod, an adjusting plate and an adjusting spring. The sliding base is slidingly connected to the regulating tube, the sliding base is fixedly connected to the bubble slide, the defoaming rod is inserted into one end of the sliding base, the defoaming rod and the sliding base are slidably connected, the return spring is axially arranged along the regulating tube, one end of the return spring is fixedly connected to the defoaming rod, the other end of the return spring is fixedly connected to the sliding base, one end of the connecting rod is hinged to one end of the defoaming rod inserted into the sliding base, the other end of the connecting rod is hinged to one end of the adjusting plate, the other end of the adjusting plate passes through the sliding base radially along the sliding base, the adjusting plate is slidably connected to the sliding base, the adjusting spring is axially arranged along the regulating tube, one end of the adjusting spring is fixedly connected to the other end of the sliding base, and the other end of the adjusting spring is fixedly connected to the regulating tube.

[0021] When no rainwater flows into the regulating pipe, the sliding base blocks part of the outlet of the diverter pipe. When the rainwater flow into the regulating pipe increases, the rainwater flow rate increases, and the impact force on the bubble elimination module and the flow regulating module as a whole increases. The regulating spring is compressed, and the sliding base slides toward the outlet of the regulating pipe. The outlet cross-sectional area of ​​the diverter pipe blocked by the sliding base becomes smaller, and the flow in the diverter pipe becomes larger, thereby realizing flow regulation of the diverter pipe; at the same time, under the impact force of the water flow and the impact force generated by the collapse of bubbles, the defoaming rod is pushed toward the outlet of the regulating pipe, the reset spring is compressed, and the defoaming rod drives the connecting rod, which then pushes the regulating plate to slide outward along the radial direction of the sliding base, thereby realizing an increase in the flow cross-sectional area of ​​the regulating pipe and increasing the rainwater flow in the regulating pipe; when the flow of rainwater flowing into the regulating pipe decreases, the reset spring and the regulating spring rebound, and the flow cross-sectional area of ​​the diverter pipe and the regulating pipe decreases.

[0022] Furthermore, a defoaming needle array is provided on the end surface of the defoaming rod facing the central wheel shaft, and the defoaming needle array points to the outlet of the central wheel shaft.

[0023] The bubbles flowing out from the outlet of the center wheel shaft hit the defoaming needle array, which collapses the bubbles. The impact force generated by the bubble collapse pushes the end face of the center wheel shaft at the same time, thereby generating a certain thrust on the center wheel shaft. When the rainwater flow rate increases, the bubble content in the rainwater increases, and the impact force generated when the bubbles collapse increases, thereby increasing the thrust on the center wheel shaft, thereby realizing rapid adjustment of the rainwater flow in the regulating pipe.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention is equipped with a garbage screening module. Driven by rainwater, large-volume garbage hits the drum. With the continuous impact of rainwater, the large-volume garbage flows along the drum to the entrance of the garbage bin and finally enters the garbage bin to be collected;

[0026] 2. The present invention is provided with a bubble elimination module. When rainwater flows through the impeller, it drives the impeller and the bubble ring to rotate. When the impeller rotates, the bubbles in the rainwater will converge to the central axis of the regulating tube under the influence of centrifugal force, preventing the bubbles from bursting at the tube wall of the regulating tube, causing cavitation of the regulating tube wall, and greatly reducing the service life of the regulating tube. One side of the blade exceeds the inlet end of the central wheel shaft, and a vortex is generated before the inlet of the central wheel shaft, so that the bubbles converge to the central axis of the regulating tube in advance, and then enter the central wheel shaft. The inlet aperture of the central wheel shaft is larger than the outlet aperture. The closer to the outlet of the central wheel shaft, the greater the water flow pressure. The tiny bubbles merge near the outlet of the central wheel shaft, which is convenient for the subsequent collapse of the bubbles.

[0027] 3. The present invention is provided with a flow regulating module. When the flow of rainwater flowing into the regulating pipe increases, the flow rate of rainwater increases, the impact force on the bubble elimination module and the flow regulating module as a whole increases, the regulating spring is compressed, and the sliding base slides toward the outlet of the regulating pipe. The outlet cross-sectional area of ​​the shunt pipe blocked by the sliding base becomes smaller, and the flow in the shunt pipe becomes larger, thereby realizing flow regulation of the shunt pipe; at the same time, under the impact force of the water flow and the impact force generated by the collapse of bubbles, the defoaming rod is pushed toward the outlet of the regulating pipe, the reset spring is compressed, and the defoaming rod drives the connecting rod, which then pushes the regulating plate to slide outward along the radial direction of the sliding base, thereby realizing an increase in the cross-sectional area of ​​the flow channel in the regulating pipe and increasing the rainwater flow in the regulating pipe; when the flow of rainwater flowing into the regulating pipe decreases, the reset spring and the regulating spring rebound, and the cross-sectional area of ​​the flow channel of the shunt pipe and the regulating pipe decreases.

[0037] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0038] Example: Figure 1 - Figure 8 As shown, the present invention provides a technical solution for a rainwater garden reuse device with a flow adaptive function:

[0039] like Figure 1-Figure 3 As shown, the reuse equipment includes a filter barrel 1, a connecting pipe 2 and a water reservoir 3. The outlet of the filter barrel 1 is connected to one end of the connecting pipe 2, and the other end of the connecting pipe 2 is connected to the inlet of the water reservoir 3. A regulating pipe 4 is provided at the inlet of the filter barrel 1, and the outlet end of the regulating pipe 4 is connected to the inlet of the filter barrel 1. A garbage screening module 5, a bubble elimination module 6 and a flow regulating module 7 are provided in the regulating pipe 4. The garbage screening module 5 is provided at the inlet of the regulating pipe 4, and the garbage screening module 5 and the regulating pipe 4 are rotatably connected. The flow regulating module 7 is provided at the outlet of the regulating pipe 4, and the flow regulating module 7 and the regulating pipe 4 are slidingly connected. The bubble elimination module 6 is provided in the regulating pipe 4, and the bubble elimination module 6 is located between the garbage screening module 5 and the flow regulating module 7. The bubble elimination module 6 and the flow regulating module 7 are fixedly connected, and the bubble elimination module 6 and the regulating pipe 4 are slidingly connected.

[0040] When it rains, large amounts of garbage will be mixed in the rainwater. The garbage mixed with rainwater enters from the inlet of the regulating pipe 4. The garbage screening module 5 will screen out and collect the large amount of garbage from the regulating pipe 4. Then the rainwater passes through the bubble elimination module 6, driving the bubble elimination module 6 to converge the bubbles to the central axis of the regulating pipe 4. Then, most of the bubbles are eliminated in cooperation with the flow regulating module 7. When the rainwater flow rate increases, the force of the rainwater pushing the bubble elimination module 6 and the flow regulating module 7 increases, and the flow regulating module 7 gradually opens, so that the cross-sectional area of ​​the flow channel in the regulating pipe 4 increases, thereby increasing the flow rate of rainwater flowing into the filter barrel 1. After being filtered by the filter barrel 1, it is collected by the water reservoir 3, thereby improving the rainwater collection efficiency. At the same time, the force generated by the bubbles in the rainwater when they burst will also assist the regulation of the flow regulating module 7; when the rainwater flow rate becomes smaller, the push of the bubble elimination module 6 and the flow regulating module 7 by the rainwater decreases, and the bubble elimination module 6 and the flow regulating module 7 slide toward the inlet of the regulating pipe 4, and the cross-sectional area of ​​the flow channel in the regulating pipe 4 decreases, thereby realizing adaptive regulation of the flow rate.

[0041] like Figure 2 and Figure 3 As shown, diversion pipes 41 are provided on both sides of the regulating pipe 4 in the horizontal direction, the inlets of the diversion pipes 41 on both sides are located between the garbage screening module 5 and the bubble elimination module 6, and the outlets of the diversion pipes 41 on both sides are located between the bubble elimination module 6 and the flow regulating module 7.

[0042] When the rainwater flow rate suddenly increases, the high-speed flowing rainwater will cause a large impact force on the bubble elimination module 6 and the flow regulation module 7, thereby damaging the bubble elimination module 6 and the flow regulation module 7, reducing the service life of the recycling equipment. By setting up a diversion pipeline 41, when the rainwater flow rate suddenly increases, the rainwater in the main channel of the regulating pipe 4 will be diverted, reducing the impact force on the bubble elimination module 6 and the flow regulation module 7, and improving the service life of the recycling equipment.

[0043] like Figure 2 As shown, a trash bin 42, a filter plate 43 and a filter tube 44 are provided on one side of the regulating tube 4 in the horizontal direction. The inlet of the trash bin 42 is connected to the regulating tube 4. The inlet of the trash bin 42 is located between the inlet of the regulating tube 4 and the garbage screening module 5. The outlet of the trash bin 42 is connected to one end of the filter tube 44. A filter plate 43 is provided in one end of the filter tube 44. The filter plate 43 and the filter tube 44 are fixedly connected. The outlet of the trash bin 42 is connected to the inlet of the filter barrel 1.

[0044] The large volume of garbage mixed in the rainwater is blocked by the garbage screening module 5 and carried into the garbage bin 42 by the water flow for collection. The rainwater in the garbage bin 42 is then filtered through the filter plate 43 and enters the filter barrel 1 for filtration through the filter pipe 44. The filter pipe 44 connecting the garbage bin 42 and the filter barrel 1 is provided, which effectively prevents the rainwater from being collected in the garbage bin 42 and then backflowing, bringing the garbage in the garbage bin 42 back into the regulating pipe 4 and clogging the regulating pipe 4.

[0045] like Figure 2 and Figure 3 As shown, the garbage screening module 5 includes multiple rollers 51, which are vertically arranged and rotatably connected to the regulating pipe 4. The closer the multiple rollers 51 are to the entrance of the garbage bin 42, the farther they are from the entrance of the regulating pipe 4. The entrance of the garbage bin 42 is located between the roller 51 closest to the entrance of the garbage bin 42 and the entrance of the regulating pipe 4.

[0046] Driven by the rain, large-volume garbage hits the drum 51. With the continuous impact of the rain, the large-volume garbage flows along the drum 51 to the entrance of the garbage bin 42 and finally enters the garbage bin 42. The drum 51 is rotatably connected to the regulating pipe 4, so that when the large-volume garbage hits the drum 51, it flows along the drum 51 to the garbage bin 42.

[0047] like Figure 4 、 Figure 6 and Figure 7 As shown, the bubble elimination module 6 includes a bubble slide 61, a bubble rotating ring 62 and an impeller 63. The bubble slide 61 is located between the inlet of the diversion pipeline 41 and the flow regulating module 7. The bubble slide 61 and the flow regulating module 7 are fixedly connected. The bubble slide 61 and the regulating tube 4 are slidingly connected. The bubble rotating ring 62 and the bubble slide 61 are rotatably connected. The outer edge of the impeller 63 is fixedly connected to the bubble rotating ring 62. The central axis of the impeller 63 coincides with the rotation axis of the bubble rotating ring 62.

[0048] When rainwater flows through the impeller 63, it drives the impeller 63 and the bubble ring 62 to rotate. When the impeller 63 rotates, the bubbles in the rainwater will converge toward the central axis of the regulating tube 4 under the influence of centrifugal force, preventing the bubbles from bursting at the wall of the regulating tube 4, causing cavitation on the wall of the regulating tube 4, and greatly reducing the service life of the regulating tube 4.

[0049] like Figure 4 、 Figure 6 and Figure 7As shown, the impeller 63 includes a central wheel shaft 64 and blades 65, one end of the blade 65 is fixedly connected to the central wheel shaft 64, and the other end of the blade 65 is fixedly connected to the bubble rotating ring 62. One side of the blade 65 extends beyond the inlet end of the central wheel shaft 64, the inlet aperture of the central wheel shaft 64 is larger than the outlet aperture, and the central axis of the central wheel shaft 64 coincides with the rotation axis of the bubble rotating ring 62.

[0050] One side of the blade 65 extends beyond the inlet end of the center wheel shaft 64, generating a vortex before the inlet of the center wheel shaft 64, causing the bubbles to converge toward the central axis of the regulating tube 4 in advance, thereby entering the center wheel shaft 64. The inlet aperture of the center wheel shaft 64 is larger than the outlet aperture. The closer to the outlet of the center wheel shaft 64, the greater the water flow pressure. The tiny bubbles merge near the outlet of the center wheel shaft 64, which facilitates the subsequent collapse of the bubbles.

[0051] like Figure 4 As shown, a shear rod 66 is provided at the outlet of the central wheel shaft 64 . The shear rod 66 passes through the central wheel shaft 64 along the radial direction of the central wheel shaft 64 . The shear rod 66 and the central wheel shaft 64 are fixedly connected.

[0052] The shear rod 66 is responsible for initially collapsing the bubbles merged at the outlet of the central wheel shaft 64, thereby improving the bubble collapse efficiency.

[0053] like Figure 3-Figure 6 and Figure 7 When the locking cam 75 is in the unlocking state, the locking cam 73 is in the unlocking state, and the locking cam 73 is in the unlocking state, and the locking cam 73 is in the unlocking state.

[0054] When no rainwater flows into the regulating pipe 4, the sliding base 72 blocks part of the outlet of the shunt pipe 41. When the flow of rainwater flowing into the regulating pipe 4 increases, the flow rate of rainwater increases, the impact force on the bubble elimination module 6 and the flow regulating module 7 as a whole increases, the regulating spring 76 is compressed, and the sliding base 72 slides toward the outlet of the regulating pipe 4. The outlet cross-sectional area of ​​the shunt pipe 41 blocked by the sliding base 72 becomes smaller, and the flow in the shunt pipe 41 becomes larger, thereby realizing the flow regulation of the shunt pipe 41. At the same time, when the water flow is full, the shunt pipe 41 is opened. Under the impact force and the impact force generated by the collapse of bubbles, the defoaming rod 71 is pushed toward the outlet of the regulating pipe 4, the reset spring 73 is compressed, the defoaming rod 71 drives the connecting rod 74, and the connecting rod 74 pushes the regulating plate 75 to slide radially outward along the sliding base 72, thereby increasing the cross-sectional area of ​​the flow channel in the regulating pipe 4 and increasing the rainwater flow in the regulating pipe 4; when the flow rate of rainwater flowing into the regulating pipe 4 decreases, the reset spring 73 and the regulating spring 76 rebound, and the cross-sectional area of ​​the flow channel of the shunt pipe 41 and the regulating pipe 4 decreases.

[0055] like Figure 4 、 Figure 5 and Figure 7 As shown, a defoaming needle array 77 is provided on the end surface of the defoaming rod 71 facing the central wheel shaft 64 , and the defoaming needle array 77 points to the outlet of the central wheel shaft 64 .

[0056] The bubbles flowing out from the outlet of the center wheel shaft 64 collide with the defoaming needle array 77, and the defoaming needle array 77 collapses the bubbles. The impact force generated by the collapse of the bubbles simultaneously pushes the end face of the center wheel shaft 64, thereby generating a certain thrust on the center wheel shaft 64. When the rainwater flow rate increases, the bubble content in the rainwater increases, and the impact force generated when the bubbles collapse increases, thereby increasing the thrust on the center wheel shaft 64, thereby realizing rapid adjustment of the rainwater flow in the regulating pipe 4.

[0057] The working principle of the present invention is as follows: when it rains, large amounts of garbage will be mixed in the rainwater. The garbage mixed with rainwater enters from the inlet of the regulating pipe 4. The garbage screening module 5 screens out and collects the large amount of garbage from the regulating pipe 4. Then the rainwater passes through the bubble elimination module 6, driving the bubble elimination module 6 to converge the bubbles to the central axis of the regulating pipe 4. Then, most of the bubbles are eliminated in cooperation with the flow regulating module 7. When the rainwater flow rate increases, the force of the rainwater pushing the bubble elimination module 6 and the flow regulating module 7 increases, and the flow regulating module 7 gradually opens, increasing the cross-sectional area of ​​the flow channel in the regulating pipe 4, thereby increasing the flow rate of rainwater flowing into the filter barrel 1. After being filtered by the filter barrel 1, it is collected by the water reservoir 3, thereby improving the rainwater collection efficiency. At the same time, the force generated by the bubbles in the rainwater when they burst will also assist the regulation of the flow regulating module 7; when the rainwater flow rate becomes smaller, the push of the bubble elimination module 6 and the flow regulating module 7 by the rainwater decreases, and the bubble elimination module 6 and the flow regulating module 7 slide toward the inlet of the regulating pipe 4, and the cross-sectional area of ​​the flow channel in the regulating pipe 4 decreases, thereby realizing adaptive regulation of the flow rate.

[0058] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
