[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. At the same time, it should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0015] like Figure 1As shown, the utility model provides a toilet black water treatment and recovery system, which includes a crushing box body 1 and a filtering box body 2, wherein the feed end of the crushing box body 1 is provided with a black water feed port 11 for receiving black water, and the crushing box body 1 is provided with a material crushing component for crushing large particles in the black water into small particles; the filtering box body 2 is provided with an impeller 21, a filtering component 23 and a grey water collection tank 24 in sequence along the forward direction of the water flow; the discharge end of the grey water collection tank 24 is connected to the circulating water tank 4 through a first pipeline 31, and the feed end of the impeller 21 is connected to the discharge end of the crushing box body 1 through a second pipeline 32.

[0016] It should be noted that, for the convenience of description, the wastewater in the crushing box 1 (toilet flushing water containing large particles of feces) is called black water, and the wastewater in the filter box 2 (toilet flushing water containing small particles of feces) is called sewage. The solute space where the impeller 21 in the filter box 2 is located can also be called a sewage treatment tank 22 (that is, the solute space between the filter component 23 and the sewage feed port 25). People can salvage the feces in the sewage tank into the feces collection room to recycle and reuse the feces (such as as biological fertilizer).

[0017] During actual operation, the crushing box 1 is provided with a black water feed port 11 and a black water discharge port 12, and the filtering box 2 is provided with a sewage feed port 25 and a sewage discharge port 26. The material crushing component is mainly used for crushing large particles (such as feces) in the black water, and the impeller 21 is mainly used for introducing the black water discharged from the crushing box 1 into the sewage treatment tank 22 and the filtering component 23 in sequence, so that the filtering component 23 can filter the sewage to obtain grey water (i.e. recycled water).

[0018] In actual operation, the crushing box 1 is used to receive black water and crush the large particles (such as feces) in the black water into small particles (also known as feces residue), and finally discharge the mixture of small particles and black water (referred to as sewage) and introduce it into the sewage treatment tank 22 and the filter component 23 in turn; the filter box 2 is mainly used to filter the sewage to form grey water, which can be used for secondary flushing of the material crushing components in the crushing box 1, and can also be reused by the external circulating water tank 4 to save water.

[0019] The material crushing component is a grille 13 disposed in the crushing box 1. In this way, the present application also realizes the arrangement of the material crushing component. Under the impact of the water flow, the grille 13 can cut the feces in the black water, thereby cutting the feces with a longer length into feces residue, so as to facilitate the introduction of the black water (sewage) containing the feces residue into the sewage treatment tank 22.

[0020] The grid net 13 has multiple layers, and the mesh area of ​​the multiple layers of the grid net 13 decreases successively along the advancing direction of the material. In this way, under the joint action of the multiple layers of the grid net 13, the feces with a longer length will be gradually cut into feces residue.

[0021] The mesh area of ​​the grid net 13 is 1 to 10 cm 2 , so that the size of the feces residue can be as small as possible, making it easier for people to recycle and reuse the feces in the sewage treatment tank 22.

[0022] The filter assembly 23 includes an electrolytic filter box 231 and an iron-carbon filler layer 232, and the iron-carbon filler layer 232 is located between the electrolytic filter box 231 and the impeller 21. In this way, the present application also realizes the layout of the filter assembly 23 structure, the iron-carbon filler layer 232 can perform primary filtration on the sewage, and the electrolytic filter box 231 can perform electrolytic filtration on the sewage after primary filtration to reduce the bacterial content in the sewage, thereby turning the sewage into medium water.

[0023] The discharge end of the reclaimed water collection tank 24 is connected to the black water feed port 11 through a third pipeline 33, and a water diversion pump 5 is provided on the third pipeline 33. Under the action of the water diversion pump 5, the present application allows the filtered reclaimed water to flush the material crushing assembly, thereby reducing the adhesion of materials on the grid net 13 and preventing the grid net 13 from being blocked.

[0024] During actual operation, the impeller 21 will attract the black water (sewage) in the crushing box into the sewage treatment tank 22, and guide the sewage in the sewage treatment tank 22 into the filter assembly 23 to obtain reclaimed water.

[0025] In actual operation, the working principle of this application is:

[0026] The black water inlet 11 of the crushing box 1 introduces black water (containing feces), and the black water gradually falls downward in the crushing box 1 under the action of gravity. When the feces in the black water passes through the multi-layer grid mesh 13, under the action of its own gravity and the impact force of the water flow, it will be gradually divided into feces residue (that is, small particles) by the grid mesh 13. Finally, the black water and feces residue will be discharged from the black water outlet 12 of the crushing box 1.

[0027] When the impeller 21 is in working state, it will attract the black water in the crushing box into the sewage treatment tank 22, and introduce the sewage in the sewage treatment tank 22 into the filter component 23. After the sewage is filtered by the filter component 23, it will obtain grey water, which can be used for secondary flushing of the material crushing components in the crushing box 1, and can also be reused by the external circulating water tank 4 to save water, so that the present application realizes the recycling and reuse of water resources.

[0028] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
