[0029] Example

[0030] like Figures 1-5 As shown, this utility model provides a technical solution: an environmentally friendly garden wastewater treatment device, including a treatment cylinder 1 and several water collection cylinders 5 connected to the treatment cylinder 1. The treatment cylinder 1 is made of high-strength, corrosion-resistant engineering plastic material, which can stably withstand the pressure impact when garden wastewater flows in. In addition, this material has good resistance to acid and alkali components in wastewater, which can effectively prevent the cylinder wall from being corroded and ensure the long-term reliable operation of the device. Several water collection cylinders 5 are arranged in a circumferential array on the outer wall of the treatment cylinder 1. The water collection cylinders 5 are also made of high-quality engineering plastic and are precision injection molded to match the material characteristics of the treatment cylinder 1, ensuring overall durability. The drain pipe 52 connected to the lower part of the water collection cylinder 5 is made of flexible rubber material with a smooth inner wall. This not only ensures the smooth discharge of treated water, but also prevents leakage due to good sealing, so that the water can be used smoothly for non-potable purposes such as garden irrigation, achieving water resource recycling. The inner wall of the treatment cylinder 1 is layered with filter elements 2 and filter screens 3 in sequence. Filter elements 2 are in contact with the inner wall of the treatment cylinder 1, and filter screens 3 are in contact with the inner wall of filter elements 2. Filter elements 2 are composed of multiple layers of composite filter materials. These materials are treated with a special process and work synergistically to significantly filter fine particles and some organic matter in wastewater.

[0031] The filter screen 3 is woven from stainless steel wire. The mesh is scientifically designed according to the interception requirements, which can effectively block larger debris such as fallen leaves and plastic fragments, playing a key role in the initial filtration. The treatment cylinder 1 is also equipped with a cleaning mechanism, which includes a lifting component set inside the treatment cylinder 1 and a servo motor 4 that drives the lifting component to move up and down. The lifting component consists of a lifting sleeve 6 and an annular lifting plate 61 fixedly connected to its lower edge. The outer wall of the annular lifting plate 61 is tightly fitted with the inner wall of the filter screen 3. When moving, it can clean up the accumulated debris along the inner wall of the filter screen 3. The servo motor 4 is installed at the bottom of the treatment cylinder 1, and its output shaft is connected to the lifting sleeve 6 through a transmission structure to provide power for the cleaning operation.

[0032] The transmission structure includes a lead screw 7 and a threaded sleeve 71. One end of the lead screw 7 is precisely mounted on the output shaft of the servo motor 4 via a high-strength coupling, ensuring accurate synchronous rotation. The other end of the lead screw 7 passes through the processing cylinder 1 and engages with the threaded sleeve 71. The upper end of the threaded sleeve 71 is tightly connected to the lifting sleeve 6. When the servo motor 4 starts and drives the lead screw 7 to rotate, due to the precise thread engagement between the lead screw 7 and the threaded sleeve 71, the threaded sleeve 71 will move linearly up and down along the lead screw 7, thereby driving the lifting sleeve 6 and the annular lifting plate 61 to move up and down, thus initiating the debris cleaning process.

[0033] The cleaning mechanism is also equipped with a protective pipe 8. The lower edge of the protective pipe 8 is fixedly connected to the bottom wall of the treatment cylinder 1 by a strong welding process, and is sleeved around the lead screw 7 and the threaded sleeve 71. The protective pipe 8 is made of corrosion-resistant plastic material, which can effectively isolate the lead screw 7 from the sewage in the treatment cylinder 1, prevent corrosive substances in the sewage from contacting the lead screw 7, extend the service life of the lead screw 7, and reduce the risk of failures such as jamming and seizure caused by corrosion.

[0034] The outer wall of the protective pipe 8 is provided with at least one limiting sleeve 81, and the inner top wall of the lifting sleeve 6 is provided with at least one downwardly extending limiting rod 62. The limiting rod 62 cooperates with the limiting sleeve 81. The combination of the limiting sleeve 81 and the limiting rod 62 plays a guiding role, restricting the rotation of the lifting sleeve 6 and ensuring that it can only rise and fall in the vertical direction, thus ensuring that the annular lifting plate 61 can smoothly clean up debris.

[0035] Two limiting sleeves 81 are symmetrically arranged on the protective pipe 8, and two symmetrically distributed limiting rods 62 are arranged on the lifting sleeve 6 corresponding to the two limiting sleeves 81. This symmetrical layout further optimizes the guiding and stabilizing effect of the lifting sleeve 6, making the cleaning process more precise and efficient.

[0036] The limiting sleeve 81 has a limiting hole 82 that cooperates with the limiting rod 62. The diameter of the limiting hole 82 is larger than the diameter of the limiting rod 62. This design can ensure that the limiting rod 62 slides smoothly in the limiting hole 82 and effectively restrain the rotation of the lifting sleeve 6, maintaining the stability of the cleaning operation.

[0037] The side wall of the processing cylinder 1 is provided with a plurality of through holes 11, and the water collecting cylinder 5 is connected with the processing cylinder 1 through the through holes 11, which provide an outflow channel for the cleaned water, so that the water can smoothly enter the water collecting cylinder 5.

[0038] The plurality of through holes 11 are arranged in a linear array, which makes the cleaning water more uniform when penetrating into the water collecting cylinder 5, improves the water collecting efficiency, and ensures that the water resources are fully utilized.

[0039] The upper opening of the water collecting cylinder 5 is provided with a sealing cover 51, which can be opened when necessary for cleaning a small amount of impurities that may be left in the water collecting cylinder 5, or for maintenance and other operations, so as to ensure the normal use of the water collecting cylinder 5.

[0040] The bottom of the processing cylinder 1 is fixedly connected with a mounting shell 41, which is used for mounting the servo motor 4 and provides stable support for the servo motor 4, so as to ensure the smooth operation of the motor, reduce the influence of vibration on other parts of the device, and ensure the reliable operation of the entire sewage treatment device.

[0041] The working process of the utility model is as follows:

[0042] Step one, the garden sewage enters the cylinder from the water inlet of the processing cylinder 1, because the filter core 2 and the filter screen 3 are arranged in the processing cylinder 1, and the filter screen 3 is located inside the filter core 2, the sewage first impacts on the filter screen 3, the filter screen 3 intercepts larger size impurities such as larger leaves, plastic fragments and the like by virtue of the structure woven by stainless steel wires and the scientifically designed mesh, and the preliminarily filtered sewage penetrates into the filter core 2 through the filter screen 3, the filter core 2 further filters the fine particles, part of organic matters and the like impurities in the sewage by virtue of the fine structure made of multi-layer composite filter material, so that the relatively clean water after double filtration penetrates towards the inner wall direction of the processing cylinder 1.

[0043] Step two, when it is necessary to clean the sundries accumulated on the filter screen 3 and the annular lifting plate 61, the servo motor 4 in the mounting shell 41 is started, the servo motor 4 drives the lead screw 7 to rotate synchronously, under the rotating action of the lead screw 7, the threaded sleeve 71 will do linear lifting motion along the lead screw 7, when the threaded sleeve 71 rises, the lifting sleeve 6 at the upper end of the threaded sleeve 71 also rises, further drives the annular lifting plate 61 fixedly sleeved outside the lifting sleeve 6 to rise, the annular lifting plate 61 slides upwards along the inner wall of the filter screen 3, pushes the sundries previously intercepted on the filter screen 3 upwards, at the same time, the limiting rods 62 symmetrically distributed and fixedly connected to the inner top wall of the lifting sleeve 6 will move together with the lifting sleeve 6, the limiting sleeve 81 slidingly sleeved outside the limiting rods 62 plays a role of guiding and limiting the rotation of the lifting sleeve 6, ensures that the lifting sleeve 6 can only do vertical lifting motion, makes the annular lifting plate 61 stably clean the sundries, in the whole process, the protection pipe 8 plays a key role, the protection pipe 8 separates the lead screw 7 from the sewage in the treatment cylinder 1, the sewage is blocked outside the protection pipe 8 and cannot contact the lead screw 7, avoids that the corrosive substances in the sewage erode the lead screw 7, thereby effectively protecting the lead screw 7, improving the service life of the lead screw 7 and reducing the probability of faults such as jamming and locking caused by corrosion.

[0044] Step three, the clean water filtered will penetrate into the water collecting cylinder 5 through the through holes 11 on the cylinder wall of the treatment cylinder 1, then can be used for garden irrigation and other non-drinking purposes through the drain pipe 52, realizes secondary utilization of water resources, and the sealing cover 51 arranged on the inner wall of the upper end of the water collecting cylinder 5 can be opened when necessary, for cleaning a small amount of impurities possibly remaining in the water collecting cylinder 5 or performing maintenance work.

[0045] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to the embodiments without departing from the principles and spirits of the present application, the scope of the present application is defined by the appended claims and their equivalents.
