Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device. Background Technology

[0002] Wastewater treatment refers to the purification process of treating wastewater to meet the requirements of a certain water body or making it reusable. In cities, people's lives and various industrial productions generate a large amount of wastewater. If this wastewater is discharged directly without treatment, it will cause serious pollution to the environment. At present, the commonly used wastewater treatment method is to filter the wastewater through filtration equipment. The wastewater is transported to the filtration equipment through a conveying channel, which is usually laid underground or along the ground. The wastewater is pumped to the filtration equipment for filtration treatment. Filtration equipment is prone to damage after long-term use and requires frequent maintenance. Therefore, this invention designs a wastewater treatment equipment that is easy to maintain. Summary of the Invention

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0029] like Figures 1 to 3As shown, a wastewater treatment device includes a top cover assembly 1, a housing 2, and a filter assembly 3. The top cover assembly 1 is detachably mounted on the upper end of the housing 2 via an installation assembly. The filter assembly 3 is mounted on the lower end of the top cover assembly 1, and the housing 2 is disposed on the outer side of the filter assembly 3. The installation assembly includes a connecting port 171 on the outer side of the top cover assembly 1 and an insert 21 that matches the connecting port 171. The insert 21 is disposed on the housing 2. The connecting port 171 includes an insert 1711 and a locking interface 1712 communicating with the insert 1711. The upper end of the locking interface 1712 is provided with a limiting protrusion 1712a. The insert 21 is provided with a limiting recess 21a that matches the limiting protrusion 1712a.

[0030] Please refer to Figures 2 to 3 As shown, the mounting assembly also includes a strip-shaped opening 173, which is formed on the annular connecting piece 17 and located above the connecting opening 171. The strip-shaped opening 173 extends from one end of the insertion opening 1711 to the other end of the locking interface 1712. The sidewall between the strip-shaped opening 173 and the connecting opening 171 forms a deformable piece 174. When the upper cover assembly 1 is placed on the upper end of the housing 2, the insert 21 is inserted into the insertion opening 1711. Rotating the upper cover assembly 1 causes the annular connecting piece 17 to rotate, and the insert 21 pushes against the deformable piece 174 and deforms upward, causing the limiting protrusion 1712a to engage in the limiting recess, thereby locking the upper cover assembly 1 and the housing 2. When disassembling, the knob is turned in the opposite direction to disengage the limiting protrusion 1712a from the limiting recess, thereby separating the upper cover assembly 1 from the housing 2.

[0031] Please refer to Figure 4 and 5 The upper cover assembly 1 includes an upper cover body 11, a sewage inlet pipe (not shown in the figure), and a filtered water outlet pipe (not shown in the figure). The upper cover body 11 is generally circular, with an inlet 12 on one side and an outlet 13 on the other side. The sewage inlet pipe is connected to the inlet 12, and the filtered water outlet pipe is connected to the filtered water outlet pipe. Sewage is input into the device of the present invention through the sewage inlet pipe, filtered by the device, and flows out from the filtered water outlet pipe. The device of the present invention is provided with a sewage inlet pipe and a filtered water outlet pipe to facilitate connection between the device and other devices. The specific connection method will not be described in detail here.

[0032] A connecting pipe 16 is provided in the upper cover 11, and the lower end of the connecting pipe 16 extends into the housing 2. The inlet 12 is connected to the upper end of the connecting pipe 16. A first connecting cavity 14 is formed on the upper cover 11 outside the connecting pipe 16. A second connecting cavity 15 extends upward from the side of the first connecting cavity 14 near the outlet 13, and the outlet 13 is connected to the second connecting cavity 15. Wastewater enters directly into the connecting pipe 16 from the inlet 12, then enters the filter assembly 3. The filtered water flows into the housing 2 after being filtered by the filter assembly 3, extends upward to the first connecting cavity 14 and the second connecting cavity 15, and then flows out from the outlet 13.

[0033] Please refer to Figure 6 As shown, the filter assembly 3 includes a filter screen 31 and a cylindrical support frame 32. The upper end of the cylindrical support frame 32 is disposed on the lower side of the connecting channel. The cylindrical support frame 32 has several through holes 321. The filter screen 31 is attached to the outer surface of the cylindrical support frame 32. Filtered water enters the cylindrical support frame 32 through the connecting pipe 16, then flows through the through holes 321 to the filter screen 31 for filtration, and finally flows out from the outlet 13.

[0034] Please refer to Figure 7As shown, the cylindrical support frame 32 is installed at the lower end of the connecting pipe 16 via a quick-installation assembly. The quick-installation assembly includes a first strip 161, a second strip 162, and a third strip 163. The end of the connecting channel is split by several slits 168 to form an elastic component 164 and a connecting component 165. The first strip 161 is disposed inside the connecting channel and located on the elastic component 164. The second strip 162 is disposed on the connecting component 165 and located on the inner wall of the connecting channel, serving to limit and block the fourth strip 322. The third strip 163 is disposed between the first strip 161 and the second strip 162 and located on the inner wall of the connecting channel. An annular protrusion 166 is disposed on the inner wall of the connecting channel and above the second strip 162. The upper end of the cylindrical support frame 32 is provided with a fourth strip 322 and a fifth strip 323. The fourth strip 322 and the fifth strip 323 are arranged sequentially along the outer surface of the cylindrical support frame 32, and the width of the fourth strip 322 is greater than that of the fifth strip 323. During installation, the upper end of the cylindrical support frame 32 is aligned with the lower end of the connecting channel. The fourth strip 322 is aligned with the sliding channel 167 formed by the first strip 161 and the second strip 162 (the side away from the third strip 163). The cylindrical support frame 32 is pushed into the inner cavity of the connecting channel along the sliding channel 167. The annular protrusion 166 at the top acts as a barrier, allowing the fourth strip 322 and the fifth strip 323 to reach the expected position, with the fourth strip 322 above the first strip 161 and the fifth strip 323 in the sliding channel 167. The first strip 161 and the second strip 162 are located on its two sides. Rotating the cylindrical support frame 32 causes the fifth strip 323 to push against the first strip 161, and the elastic component 164 deforms outward, so that the fifth strip 323 can bypass the first strip 161 and reach its other side. At the same time, the fourth strip 322 is positioned above the first strip 161 and the third strip 163, and the lower end of the fourth strip 322 is exactly against the upper end of the first strip 161 and the upper end of the third strip 163, thereby locking the upper end of the circular support frame in the connecting channel.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
