The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0029] This application provides a solid suspended matter recovery system, such as... Figure 1 and Figure 2 As shown, the solid suspended matter recovery system includes: a substrate 1, a separation mechanism 2, and a recovery mechanism 3; wherein, the substrate 1 has a containment space; the separation mechanism 2 is installed in the substrate 1 and communicates with the containment space, the separation mechanism 2 has a separation structure, through which wastewater is separated into solid and liquid, and the separated liquid is transported to the containment space; the recovery mechanism 3 is communicated with the separation mechanism 2 and the substrate 1; the solid-liquid mixture separated by the separation mechanism 2 enters the recovery mechanism 3, and the recovery mechanism 3 transports the liquid in the solid-liquid mixture to the containment space.

[0030] In some embodiments of this application, the substrate 1 includes a sewage tank 11, which has a accommodating space and is provided with a first inlet 12.

[0031] For example, the base 1 can be a sewage tank 11, with a first inlet 12 on the top of the sewage tank 11. Sewage is added to the sewage tank 11 or other components in the sewage tank 11 through the first inlet 12, and the treated sewage can flow into the sewage tank 11 for collection.

[0032] As another example, a baffle, such as a flip-up cover, can be installed on the top of the sewage tank 11 to protect the contents inside the sewage tank 11 and reduce the probability of spillage or leakage.

[0033] In the above embodiments, the base 1 is provided to store the treated wastewater and to provide an installation environment for other structures.

[0034] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the separation mechanism 2 includes a housing 21, which is installed in the sewage tank 11. The housing 21 has a second inlet 22, the direction of which is the same as or nearly the same as the direction of the first inlet 12. A separation element 23 is installed inside the housing 21. The separation element 23 has a separation mechanism 2. The separation element 23 separates the solids in the sewage to the bottom of the housing 21 and separates the liquids in the sewage to the upper area inside the housing 21.

[0035] For example, the separation component can be configured to include a housing 21, which can be installed inside the wastewater tank 11. For instance, the housing 21 can be a receiving tank, which can be installed in the top region inside the wastewater tank 11. The housing 21 has a second inlet 22. For instance, a first inlet 12 can be located at the top of the housing 21, and the second inlet 22 can be located at the top of the wastewater tank 11.

[0036] In another example, a separator 23 can be installed inside the tank 21. For example, the separator 23 can be a solid-liquid hydrocyclone. The solid-liquid hydrocyclone can be installed at the top of the tank 21. The sewage inlet of the solid-liquid hydrocyclone is duckbill-shaped to guide the sewage to generate a certain centrifugal force inside the solid-liquid hydrocyclone. The mixed sewage that generates centrifugal force moves downward along the edge of the solid-liquid hydrocyclone. During the downward movement, the denser particles generate higher gravity, and the solid particles fall at a higher speed than the liquid. Under the action of the gravity of the solid particles, the solid particles enter the bottom of the tank 21.

[0037] It should be explained that the bottom of the solid-liquid hydrocyclone can be provided with a discharge port, which can be shaped like a trumpet, that is, narrow at the top and wide at the bottom, to facilitate the discharge of the solid-liquid mixture. The bottom of the box 21 can be set as a "V" shape, so that the solid-liquid mixture can be discharged from the discharge port at the bottom of the solid-liquid hydrocyclone to the bottom of the box 21; and the bottom of the box 21 is provided with an opening to facilitate the discharge of the solid-liquid mixture in the box 21 to the recovery mechanism 3.

[0038] In another example, the top of the tank 21 may be connected to a drain pipe 24. The end of the drain pipe 24 away from the top of the tank 21 may be placed in the sewage tank 11. For example, the drain pipe 24 may be installed in the tank 21 by means of bolts or other connections to reduce the probability of the drain pipe 24 shaking during sewage treatment.

[0039] The wastewater level in the receiving tank can be higher than the wastewater level in the wastewater tank 11, while the wastewater level in the wastewater tank 11 can be controlled to be two meters lower than the receiving tank. This ensures that the pressure difference between the receiving tank and the wastewater tank 11 is two kilopascals, which can improve the recovery efficiency of suspended solids in wastewater and reduce the wastewater content of suspended solids, thus facilitating subsequent treatment.

[0040] In the above embodiment, the presence of the housing 21 facilitates the installation of the separator 23 and allows for the containment of the separated liquid. The separator 23 separates the suspended solids and liquid in the wastewater. The presence of the drain pipe 24 allows the liquid separated from the housing 21 to be drained into the wastewater tank 11 for further treatment, making the process flexible and convenient.

[0041] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the recycling mechanism 3 includes a filter device 31, which is located at the bottom of the sewage tank 11. A discharge pipe 32 is provided between the filter device 31 and the tank body 21. The discharge pipe 32 is inserted into the sewage tank 11, with one end connected to the bottom of the tank body 21 and the other end connected to the filter device 31. The filter device 31 is provided with a filter structure 35, which filters the solid-liquid mixture flowing out from the bottom of the tank body 21.

[0042] For example, the recycling mechanism 3 may include a filter device 31, which may be placed on one side of the wastewater tank 11, and a discharge pipe 32 may be provided between the filter device 31 and the housing 21. The discharge pipe 32 extends into the wastewater tank 11, with one end of the discharge pipe 32 connected to the opening at the bottom of the housing 21 and the other end connected to the inlet of the filter device 31.

[0043] The filter device 31 is equipped with a filter structure 35, such as a filter membrane, which can be used to further filter the solid substances in the solid-liquid mixture. In this embodiment, the type of filter membrane is not specifically limited, and it is selected according to the diameter of the fixed suspended solids with different characteristics in the wastewater.

[0044] Understandably, the discharge pipe 32 can be set at a 45° angle, meaning the angle between the discharge pipe 32 and the vertical direction can be 45°. This setting facilitates the discharge of suspended solids from the housing 21 into the filter device 31. Valves can be installed on the discharge pipe 32 or at the bottom of the housing 21 to control the working progress, depending on actual needs.

[0045] In another example, a return pipe 33 is provided between the bottom outlet of the filter device 31 and the sewage tank 11. One end of the return pipe 33 can be connected to the bottom outlet of the filter device 31, and the other end can be connected to the sewage tank 11. Furthermore, a one-way valve is installed on the return pipe 33. The one-way valve is not shown in the figure. The liquid that has passed through the filter membrane is returned to the sewage tank 11 through the one-way valve and the return pipe 33.

[0046] It should be explained that the diameter of the return pipe 33 can be smaller than the diameter of the discharge pipe 32. For example, the diameter of the return pipe 33 can be two-fifths of the diameter of the discharge pipe 32.

[0047] In another example, the recycling mechanism 3 also includes a collection component 34. For example, the collection component 34 can be a collection box, which can be placed on the side of the filter device 31. The side of the filter device 31 can be provided with an outlet, and a baffle is provided at the location of the outlet. The opening and closing of the outlet is controlled by the baffle, and the solid sediment in the filter device 31 is scraped out into the collection box by the scraping structure in the filter device 31 (not shown).

[0048] Furthermore, a water outlet 13 is provided on the side of the sewage tank 11 away from the filter device 31. A valve is installed at the location of the water outlet 13. The opening and closing of the water outlet 13 is controlled by the valve, and the liquid separated from the sewage tank 11 is discharged to a designated location through the water outlet 13.

[0049] In the above embodiment, since a filter device 31 is provided, the solid and liquid in the solid suspension in the tank 21 can be separated again; since a return pipe 33 is provided, the liquid filtered by the filter device 31 can be returned to the sewage tank 11 for reuse; since a collection device 34 is provided, the sediment filtered by the filter device 31 can be collected.

[0050] The following describes the usage process of the solid suspended matter recovery system provided in this application.

[0051] First, mixed wastewater at a pressure of 30 kPa is transported to the separator 23 through the water supply pipe 4. The wastewater undergoes centrifugal force within the separator 23, separating solid sediment and some liquid, which remain at the bottom of the separator 23. The separated liquid remains at the top of the separator 23. When the separator 23 is full, it overflows to the top of the tank 21. The separated solid-liquid mixture is discharged from the bottom outlet of the tank 21 through the discharge pipe 32 into the filter device 31. The liquid in the upper part of the tank 21 is guided to the wastewater tank 11 through the diversion pipe 24. The liquid filtered by the filter device 31 flows back to the wastewater tank 11 through the return pipe 33. When the liquid level in the wastewater tank 11 rises to the designated position, the liquid is discharged from the bottom outlet of the wastewater tank 11. The solids filtered by the filter device 31 are discharged to the collection unit 34 for further processing.

[0052] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
