Description

Technical Field

[0001] This application relates to the field of garden sewage treatment technology, and in particular to an environment-friendly garden sewage treatment device and treatment method. Background Technique

[0002] A garden refers to a natural environment and recreation area created by applying engineering techniques and artistic means in a certain area, and through ways such as transforming the terrain, planting trees and flowers, building buildings, and arranging garden roads. At this time, in order to ensure the environmental protection performance of the garden and improve the utilization rate of water resources, sewage treatment devices are often set up in the garden to treat sewage, so as to obtain water bodies with better water quality, which is convenient for subsequent reuse of water resources.

[0003] The sewage treatment device includes a treatment tank, the treatment tank is connected with a water inlet pipe and a water outlet pipe, a sedimentation area and a water body purification and disinfection mechanism are arranged inside the treatment tank, and a filter screen is installed at the water inlet of the treatment tank. When in use, sewage is introduced from the water inlet pipe, and the filter screen can filter sundries such as waste products, branches, and stones in the sewage. Subsequently, the sewage will enter the treatment tank, and after sedimentation and purification and disinfection, it will be discharged from the water outlet pipe, thereby achieving the purpose of purifying the sewage and obtaining a water body with better water quality.

[0004] However, after the sundries in the sewage are filtered by the filter screen, the sundries are likely to gradually accumulate at the filter screen, resulting in poor cleaning effect of the sundries. Furthermore, after long-term use, it is easy to cause blockage of the sewage flow due to the accumulation of a large amount of sundries, thus restricting the sewage treatment. Summary of the Invention

[0005] In order to improve the cleaning effect of the sundries at the filter screen and reduce the possibility of the sundries accumulating at the filter screen, this application provides an environment-friendly garden sewage treatment device and treatment method.

[0006] In a first aspect, this application provides an environment-friendly garden sewage treatment device, adopting the following technical solution:

[0007] An environment-friendly garden sewage treatment device includes a treatment tank, the treatment tank is connected with a water inlet pipe and a water outlet pipe, a sedimentation area and a water body purification and disinfection mechanism are arranged inside the treatment tank, a filter screen is arranged at the water inlet of the treatment tank, the filter screen is movably installed in the treatment tank and one end of the filter screen is inclined downward, and the treatment tank is provided with a vibration assembly for controlling the vibration of the filter screen, and a collection box for collecting sundries is arranged below the filter screen.

[0008] By adopting the above technical solution, during use, when water flows into the treatment tank from the water inlet pipe, the provided filter screen can block the sundries in the water flow. Subsequently, the sundries can slide into the collection box, thereby realizing the function of collecting the sundries, reducing the possibility of the sundries accumulating at the filter screen, and facilitating the subsequent cleaning of the sundries. Moreover, during the collection of the sundries, the vibration assembly can be used to control the vibration of the filter screen, thereby improving the sliding effect of the sundries on the filter screen, reducing the possibility of some sundries hanging on the filter screen, making the collection effect of the sundries better, and improving the environmental protection performance of the garden.

[0009] Optionally, the vibration assembly includes a motor, a rotating rod, and a push rod. The rotating rod is connected to the output end of the motor. The rotating rod is provided with a pushing portion. Both ends of the push rod are hinged to the pushing portion of the rotating rod and the filter screen respectively.

[0010] By adopting the above technical solution, during use, starting the motor can drive the rotating rod to rotate. Subsequently, under the transmission of the push rod, the filter screen can be pulled to vibrate, thereby increasing the sliding speed of the sundries on the filter screen, facilitating the sundries to enter the collection box, and improving the collection effect of the sundries.

[0011] Optionally, a plurality of reinforcing rods are fixedly connected to the filter screen. The reinforcing rods penetrate vertically and are slidably connected to the water inlet pipe.

[0012] By adopting the above technical solution, the provided reinforcing rods can guide and support the sliding of the filter screen, making the filter screen more stable during vibration and improving the vibration effect of the filter screen.

[0013] Optionally, the collection box includes an inner box and an outer box, both of which are of an upper-opening structure. The inner box is detachably installed inside the outer box. The outer box is slidably connected to the water inlet pipe. The water inlet pipe is provided with a swinging member for controlling the reciprocating swing of the outer box.

[0014] By adopting the above technical solution, when the sundries fall into the collection box, the sundries will be collected in the inner box. Subsequently, when cleaning the sundries, only the inner box needs to be taken out. The overall swing of the collection box can be controlled by the provided swinging member, so that the sundries in the inner box can be evenly spread out, reducing the possibility of uneven stacking of the sundries in the inner box and making the collection effect of the sundries better.

[0015] Optionally, a slide rail extending along the sliding direction of the outer box is installed on the water inlet pipe. The cross-section of the slide rail is in a dovetail shape structure. The outer box is clamped and slidably connected to the slide rail.

[0016] By adopting the above technical solution, the provided slide rail can guide the sliding of the outer box, making the outer box more stable during sliding.

[0017] Optionally, the swinging member includes two swinging rods, a transmission gear, and a rack. The rack is installed on the reinforcing rod and extends along the length direction of the reinforcing rod. The transmission gear is rotatably installed on the water inlet pipe and meshes with the rack. The two swinging rods are rotatably connected to each other. One of the swinging rods is fixedly connected to the transmission gear, and the other swinging rod is hinged to the outer box.

[0018] By adopting the above technical solution, when the vibration assembly controls the sliding of the filter screen and the reinforcing rod, the reinforcing rod can not only guide and support the sliding of the filter screen, but also drive the transmission gear to rotate, thereby controlling the rotation and swinging of the two swinging rods, and then pulling the whole collection box to reciprocate and slide, so as to achieve the effect of spreading the sundries in the inner box, improve the collection effect of the sundries, and make the use effect of the reinforcing rod more abundant; moreover, only one power source is needed to control the swinging of the filter screen and the collection box at the same time, reducing energy loss.

[0019] Optionally, a transmission sleeve is sleeved on the reinforcing rod. The rack is fixedly connected to the transmission sleeve. The transmission sleeve is slidably connected with a bolt, and the reinforcing rod is provided with a jack for cooperating with the bolt.

[0020] By adopting the above technical solution, the bolt can be inserted into or away from the jack, so as to control whether the reinforcing rod and the transmission sleeve are connected to each other, thereby controlling the sliding of the rack, so as to control the swinging of the collection box according to needs. Then, when it is not necessary to spread the sundries, the sliding of the collection box can be reduced, thereby reducing wear and improving the service life.

[0021] Optionally, a top push spring for pushing the bolt to slide towards the jack is installed on the transmission sleeve. A control rod is slidably arranged on the water inlet pipe, and the control rod is connected to the bolt.

[0022] By adopting the above technical solution, when it is necessary to release the control of the rack, only need to slide the control rod away from the jack, and then the bolt can be pulled out of the jack, so as to release the connection between the transmission sleeve and the reinforcing rod, and then release the control of the sliding of the collection box; when it is necessary to control the swinging of the collection box, only need to slide the control rod close to the jack. At this time, the bolt will tend to slide towards the jack under the action of the top push spring. Then, when the jack corresponds to the bolt, the bolt can automatically penetrate into the jack under the action of the top push spring, so as to realize the connection between the reinforcing rod and the transmission sleeve, and then drive the collection box to swing reciprocally and spread the sundries.

[0023] Optionally, a positioning rod is hinged to the control rod, and a positioning groove for clamping the positioning rod is arranged on the water inlet pipe.

[0024] By adopting the above technical solution, when the control rod slides away from the jack and releases the control of the collection box, the positioning rod is rotated and clamped in the positioning groove, so as to lock the position of the control rod, ensure the stability of the plug pin in its position, and ensure that the collection box is in a state of sliding to a stop.

[0025] In a second aspect, the present application provides a sewage treatment method, including the following steps:

[0030] Debris leveling: If the debris is unevenly stacked in the inner tank, slide the control rod so that the plug pin is automatically inserted into the jack on the reinforcement rod under the action of the top push spring. Then the reinforcement rod will drive the transmission gear and the swing rod to rotate, and then push the outer tank and the inner tank to swing reciprocally to level the debris.

Detailed implementation manners

[0040] The following further describes the present application in detail with reference to the Figures 1-5 accompanying drawings.

[0041] An embodiment of the present application discloses an environment-friendly garden sewage treatment device. Referring to Figure 1 , an environment-friendly garden sewage treatment device includes a treatment tank 1, the treatment tank 1 is communicated with a water inlet pipe 2 and a water outlet pipe, a sedimentation area and a water body purification and disinfection mechanism are arranged inside the treatment tank 1, the water body purification and disinfection mechanism can be set as an ultraviolet germicidal lamp, and moreover, impurities in the water body can be sedimented by adding reagents, so that after the water flow enters the treatment tank 1 from the water inlet pipe 2, it can go through the processes of sedimentation, purification and disinfection, and finally obtain water with better quality and be output from the water outlet pipe. At the same time, a filter screen 3 is movably installed at the water inlet of the treatment tank 1, and one end of the filter screen 3 is inclined downward; a vibration assembly 4 is arranged on the treatment tank 1, so that the vibration assembly 4 can drive the filter screen 3 to vibrate, and a collection tank 5 is arranged below the filter screen 3.

[0042] During use, when water flows into the treatment tank 1 from the water inlet pipe 2, the provided filter screen 3 can block sundries in the water flow, such as branches, waste products, stones, etc. Subsequently, the sundries can slide down along the inclined direction of the filter screen 3 into the collection box 5, thereby realizing the function of collecting sundries, reducing the possibility of sundries accumulating at the filter screen 3, and facilitating the subsequent cleaning of sundries. Moreover, during the collection of sundries, the vibration assembly 4 can be used to control the vibration of the filter screen 3, thereby improving the sliding effect of the sundries on the filter screen 3, reducing the possibility of some sundries hanging on the filter screen 3, and making the collection effect of sundries better.

[0043] Refer to Figure 2 and Figure 3 At this time, the filter screen 3 is slidably connected to the water inlet pipe 2 in the vertical direction, and the vibration assembly 4 is arranged below the filter screen 3. The vibration assembly 4 includes a motor 41, a rotating rod 42, and a push rod 43. The motor 41 is installed on the water inlet pipe 2, the rotating rod 42 is coaxially and fixedly connected to the output end of the motor 41, a pushing portion is formed by bending the rotating rod 42, and both ends of the push rod 43 are hinged to the pushing portion of the rotating rod 42 and the filter screen 3 respectively. The filter screen 3 is fixedly connected with a plurality of vertically extending reinforcing rods 31, and the reinforcing rods 31 pass through and are slidably connected to the water inlet pipe 2 in the vertical direction.

[0044] During use, starting the motor 41 can drive the rotating rod 42 to rotate. Subsequently, under the transmission of the push rod 43, the filter screen 3 can be pulled to vibrate, thereby increasing the sliding speed of the sundries on the filter screen 3, facilitating the sundries to enter the collection box 5, and improving the collection effect of the sundries. Moreover, the provided reinforcing rods 31 can guide and support the sliding of the filter screen 3, making the filter screen 3 more stable when vibrating and improving the vibration effect of the filter screen 3.

[0045] In other embodiments, the vibration assembly 4 can also be set as a cylinder or a vibration motor for pushing the filter screen 3 to reciprocally slide.

[0046] Refer to Figure 4 and Figure 5 At this time, in order to further facilitate the cleaning of sundries and further improve the collection effect of sundries. The collection box 5 includes an inner box 51 and an outer box 52. Both the inner box 51 and the outer box 52 are of an upper-open structure. At this time, the water inlet pipe 2 is fixedly connected with a slide rail 521, and the cross-section of the slide rail 521 is arranged in a dovetail shape. The bottom of the outer box 52 is clamped and slidably connected to the slide rail 521, and the inner box 51 is detachably installed inside the outer box 52. The water inlet pipe 2 is provided with a swinging member 6, such that the swinging member 6 can push the entire collection box 5 to swing.

[0047] When sundries fall into the collection box 5, the sundries will be collected in the inner box 51. Subsequently, when cleaning the sundries, only the inner box 51 needs to be taken out. Moreover, during the process of the sundries falling into the inner box 51, since the sundries only fall into the inner box 51 from a single area, it is easy for sundries to accumulate in the area of the inner box 51 corresponding to the discharge end of the filter screen 3, and thus the possibility of sundries overflowing is relatively large. At this time, the overall swing of the collection box 5 can be controlled by the provided swing member 6, so that the sundries in the inner box 51 can be evenly spread, reducing the possibility of uneven stacking of sundries in the inner box 51 and making the collection effect of the sundries better. At the same time, the provided slide rail 521 can guide the sliding of the collection box 5, making the collection box 5 more stable when sliding.

[0048] Refer to Figure 4 and Figure 5 , the swing member 6 includes two swing rods 61, a transmission gear 62 and a rack 63. The rack 63 is connected to the reinforcement rod 31 and extends along the length direction of the reinforcement rod 31; the transmission gear 62 is rotatably installed on the water inlet pipe 2 and meshes with the rack 63. The two swing rods 61 are rotatably connected to each other. One of the swing rods 61 is fixedly connected to the transmission gear 62, and the other swing rod 61 is rotatably connected to the outer box 52.

[0049] When the vibration assembly 4 controls the sliding of the filter screen 3 and the reinforcement rod 31, the reinforcement rod 31 can, while guiding and supporting the sliding of the filter screen 3, also drive the transmission gear 62 to rotate, thereby controlling the rotation and swing of the two swing rods 61, and then pulling the collection box 5 to reciprocate and slide, realizing the function of spreading the sundries in the inner box 51, improving the collection effect of the sundries, and making the use effect of the reinforcement rod 31 relatively rich. Moreover, only one power source can control the swing of the filter screen 3 and the collection box 5 at the same time, reducing energy loss.

[0050] Refer to Figure 5 , a transmission sleeve 64 is coaxially sleeved and slidably connected to one of the reinforcement rods 31, and the rack 63 is fixedly connected to the outer wall of the transmission sleeve 64. The transmission sleeve 64 is radially penetrated and slidably connected with a pin 641, and the reinforcement rod 31 is provided with a jack 311. So that the pin 641 can be inserted into or away from the jack 311, thereby being able to control whether the reinforcement rod 31 and the transmission sleeve 64 are connected to each other, and thus controlling the sliding of the rack 63, so as to control the swing of the collection box 5 according to needs. Furthermore, when it is not necessary to spread the sundries, the sliding of the collection box 5 can be reduced, thereby reducing wear and increasing the service life.

[0051] The transmission sleeve 64 is provided with a pushing spring 642. The pushing spring 642 is sleeved on the bolt 641, and both ends of the pushing spring 642 are respectively connected to the bolt 641 and the transmission sleeve 64; a limiting portion 6411 is formed at one end of the bolt 641 away from the jack 311. A control rod 643 is slidably arranged on the water inlet pipe 2. The control rod 643 is provided with a connection hole 6431. The connection hole 6431 is set as a long strip groove and extends along the sliding direction of the rack 63. The bolt 641 is clamped in the connection hole 6431, and the control rod 643 is located on the side of the limiting portion 6411 facing the jack 311. The control rod 643 is hinged with a positioning rod 644, and the water inlet pipe 2 is provided with a positioning groove 645, so that the positioning rod 644 can be clamped in the positioning groove 645 after rotation.

[0052] When it is necessary to release the control of the rack 63, only need to slide the control rod 643 away from the jack 311, and then it can pull the bolt 641 out of the jack 311, so as to release the connection between the transmission sleeve 64 and the reinforcing rod 31, and then release the control of the sliding of the collection box 5. Subsequently, rotate the positioning rod 644 and clamp it in the positioning groove 645, so as to lock the position of the control rod 643 and ensure the stability of the bolt 641 when it is in the position.

[0053] When it is necessary to control the swing of the collection box 5, only need to release the restriction of the positioning rod 644 on the control rod 643, and then slide the control rod 643 close to the jack 311, and then release the restriction on the bolt 641. At this time, the bolt 641 will tend to slide towards the jack 311 under the action of the pushing spring 642. Subsequently, when the reinforcing rod 31 slides to a position where the jack 311 corresponds to the bolt 641, the bolt 641 can automatically penetrate into the jack 311 under the action of the pushing spring 642, so as to realize the connection between the reinforcing rod 31 and the transmission sleeve 64, and then control the swing member 6 to act, push the collection box 5 to swing reciprocally and spread the sundries.

[0054] In other embodiments, the swing member 6 can also be set as a cylinder, an electric push rod or a hydraulic cylinder for controlling the swing of the collection box 5.

[0055] The implementation principle of an environmental protection type garden sewage treatment device in an embodiment of the present application is as follows: during use, when water flows into the treatment tank 1 from the water inlet pipe 2, the provided filter net 3 can block sundries in the water flow, such as branches, waste products, stones, etc., and the vibration assembly 4 can control the vibration of the filter net 3. Subsequently, the sundries can slide along the inclined direction of the filter net 3 into the inner box 51 of the collection box 5, so as to realize the function of collecting the sundries, reduce the possibility of sundries accumulating at the filter net 3, and at the same time facilitate the subsequent cleaning of the sundries, improving the environmental protection performance of the garden.

[0056] Moreover, during the sundry collection process, the swing of the collection box 5 can also be controlled by sliding the control rod 643, so that sundries can be spread in the inner box 51, thereby improving the collection effect of sundries.

[0057] The embodiment of the present application also discloses a sewage treatment method. A sewage treatment method includes the following steps:

[0058] Vibrating filter screen 3: Turn on the motor 41 to control the swing of the rotating rod 42 and the push rod 43, thereby driving the filter screen 3 to vibrate;

[0059] Feeding sewage: Input sewage into the treatment tank 1 from the water inlet pipe 2 on the treatment tank 1;

[0060] Sewage purification and output: Impurities in the sewage settle and are purified and disinfected in the treatment tank 1, and finally are output from the water outlet pipe;

[0061] Sundry cleaning: The sundries on the filter screen 3 will gradually fall into the inner box 51. Take out the inner box 51 from the outer box 52 and then clean it;

[0062] Sundry leveling: If the sundries are unevenly stacked in the inner box 51, slide the control rod 643 so that the bolt 641 is automatically inserted into the jack 311 under the action of the top push spring 642, so that the reinforcement rod 31 will drive the transmission gear 62 and the swing rod 61 to rotate, and then push the outer box 52 and the inner box 51 to swing back and forth to level the sundries.

[0063] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
