[0055] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0056] See also Figures 1 to 4 The present embodiment provides a modular rural sewage resource utilization device, including a treatment box 1 and a top cover 2. The treatment box 1 is hollow inside and has an opening at the top. The internal space of the treatment box 1 is separated into a filter chamber 11, a reaction chamber 12, and a sedimentation chamber 13 by a first partition plate 10. The filter chamber 11 and the reaction chamber 12, and the reaction chamber 12 and the sedimentation chamber 13 are respectively connected through a connecting pipe 15, and a stop valve 16 is provided on the connecting pipe 15 between the reaction chamber 12 and the sedimentation chamber 13. The top cover 2 can be detachably mounted on the treatment box 1 and blocks the top opening. A water inlet pipe 5 and a drug inlet pipe 6 are penetrated on the top cover 2. The water inlet pipe 5 is connected to the filter chamber 11, and the drug inlet pipe 6 is connected to the reaction chamber 12. The treatment chamber 12 is connected, and a drain pipe 7 is connected to the sedimentation chamber 13. A water pump 8 is arranged on the drain pipe 7, and the drain pipe 7 is arranged higher than the inner bottom wall of the treatment box 1. A sewage outlet 9 connected to the outside is opened on the side wall of the treatment box 1 at the position of the filter chamber 11. A filter assembly is arranged in the filter chamber 11. The second filter plate 28 on the filter assembly is tilted in the filter chamber 11. The higher side of the second filter plate 28 is opposite to the side wall where the sewage outlet 9 is located, and the lower side is in contact with the side wall where the sewage outlet 9 is located. The second filter plate 28 can be driven by the driving assembly to move up and down along the top and bottom directions of the treatment box 1, and the second filter plate 28 is located at the sewage outlet 9 when it is raised to the limit position.

[0057] See also Figures 1 to 4When the modular rural sewage resource utilization device of this embodiment is in use, after the sewage to be treated is introduced from the water inlet pipe 5, it can first be filtered for impurities in the filter chamber 11, and then react with the medicine added from the medicine inlet pipe 6 in the reaction chamber 12, and then be statically precipitated in the sedimentation chamber 13, and finally discharged through the drain pipe 7, completing the purification and reuse of the sewage.

[0058] Also, see Figures 1 to 4 Since a filter assembly is arranged in the filter chamber 11, the filtered impurities are accumulated on the inclined second filter plate 28. As the driving assembly drives the second filter plate 28 to continuously move up and down, the impurities can automatically move to the lower side along the second filter plate 28 to complete the cleaning and collection of the impurities, and are discharged from the sewage outlet 9 when the second filter plate 28 is raised to the limit position. Therefore, the modular rural sewage resource utilization device of this embodiment has a periodic automatic cleaning function, which is beneficial to ensure the filtering effect and sufficient reaction.

[0059] It should be noted that the stop valve 16 is used to facilitate the control of the flow of sewage; the top cover 2 is used to close the treatment box 1, and after removing the top cover 2, the maintenance personnel can inspect and maintain the interior of the treatment box 1; the water pump 8 is used to discharge the treated sewage.

[0060] Preferably, see Figure 4 and Figure 5 The driving assembly includes a motor 26, a driving shaft 27 and a cam 30. The motor 26 and the driving shaft 27 are both arranged on the top outer wall of the processing box 1. The output shaft of the motor 26 is axially connected with the driving shaft 27 and drives the driving shaft 27 to rotate. The cam 30 is fixed on the driving shaft 27. The filtering assembly includes a connecting bracket 29 and a second filter plate 28. The connecting bracket 29 is an arched structure and is sleeved on the top side wall of the processing box 1. One side of the connecting bracket 29 is located inside the processing box 1 and is fixedly connected to the higher side of the second filter plate 28. The other side of the connecting bracket 29 is located outside the processing box 1 and vertically abuts against the cam 30 below. The top cover 2 is provided with an avoidance groove at the buckling position with the processing box 1. The connecting bracket 29 can be lifted and lowered in the avoidance groove. The motor 26 of the driving assembly drives the cam 30 to rotate, and the cam 30 can push the upper connecting bracket 29 to move up and down continuously, thereby driving the second filter plate 28 to move up and down, so as to achieve the effect of transporting and discharging impurities.

[0061] Preferably, see Figure 6 and Figure 7, a stirring assembly is arranged in the reaction chamber 12, and the stirring assembly includes a first mounting plate 39, a second mounting plate 40 and a stirring shaft 36. The inner walls on both sides of the processing box 1 are provided with two sliding channels extending in the top and bottom directions by attaching second limiting strips 37. The first mounting plate 39 is located at the bottom of the processing box 1, and the two ends of the first mounting plate 39 are respectively accommodated in a sliding channel. The second mounting plate 40 is detachably mounted on the top of the processing box 1. The two stirring shafts 36 are arranged in parallel and spaced apart, and one end of the stirring shaft 36 is rotatably connected to the first mounting plate 39, and the other end can be rotatably axially penetrated from the second mounting plate 40. A plurality of protruding stirring rods 38 are evenly spaced on the outer wall of the stirring shaft 36. A third synchronous wheel 41 is installed at the protruding end of the stirring shaft 36. The third synchronous wheels 41 on the two stirring shafts 36 are connected by synchronous belt transmission. A second synchronous wheel 35 is installed at the protruding end of one stirring shaft 36, and the second synchronous wheel 35 is connected by synchronous belt transmission to the first synchronous wheel 34 on the driving assembly.

[0062] See also Figure 6 and Figure 7 When the first synchronous wheel 34 on the driving assembly rotates, it will drive the second synchronous wheel 35 to rotate synchronously, and then drive the third synchronous wheel 41 on the stirring shaft 36 installed with the second synchronous wheel 35 to rotate, and then drive another stirring shaft 36 to rotate synchronously with the stirring shaft 36 through the synchronous belt, and finally make the multiple stirring rods 38 on the two stirring shafts 36 fully stir the sewage in the reaction chamber 12, so that the sewage and the sewage treatment chemicals are fully mixed to ensure sufficient reaction.

[0063] It should be noted that in the present device, after the user removes the top cover 2, the second filter plate 28 and the two stirring shafts 36 can be removed. The second filter plate 28 can be pulled out by lifting it upwards, while the two stirring shafts 36 need to first release the connection between the second mounting plate 40 and the processing box 1, and then, after ensuring that there are no other parts connected, they can be pulled out upwards. They can be replaced accordingly after the equipment is worn or damaged, and the degree of modularity is high.

[0064] Preferably, see Figure 5 and Figure 6 The driving assembly includes a motor 26, a driving shaft 27 and a fixing plate. The motor 26, the driving shaft 27 and the fixing plate are all arranged on the top outer wall of the processing box 1. The output shaft of the motor 26 is axially connected with the driving shaft 27 and drives the driving shaft 27 to rotate. A first bevel gear 31 is fixed on the driving shaft 27. A rotatable connecting shaft 33 is arranged on the fixing plate. A second bevel gear 32 and a first synchronous wheel 34 are arranged on the connecting shaft 33. The second bevel gear 32 is meshed with the first bevel gear 31. The first synchronous wheel 34 is connected to the second synchronous wheel 35 through a synchronous belt.

[0065] See also Figure 5 and Figure 6When the motor 26 is working, it will drive the driving shaft 27 to rotate together with the first bevel gear 31, and then drive the second bevel gear 32 to rotate synchronously. Because the second bevel gear 32 and the first synchronous wheel 34 are also provided on the connecting shaft 33, as the second bevel gear 32 rotates, the first synchronous wheel 34 will rotate together with the connecting shaft 33, and finally the first synchronous wheel 34 and the second synchronous wheel 35 are rotated synchronously through the synchronous belt to realize the driving of the stirring assembly.

[0066] Preferably, see Figure 1 and Figure 5 In this embodiment, a side protective shell 3 is provided on the outer wall of one side of the processing box 1, and the motor 26 and the driving shaft 27 are both located in the side protective shell 3 to protect these components from the influence of the external environment and extend the service life of the device.

[0067] Preferably, see Figure 3 A second partition 14 is vertically extended from the inner bottom wall of the sedimentation chamber 13 to the top, and the second partition 14 is located on the side of the sedimentation chamber 13 close to the reaction chamber 12, and the top height of the second partition 14 is lower than the setting height of the sewage outlet 9. The setting of the second partition 14 can simply intercept and buffer the sewage entering the sedimentation chamber 13, reducing the impact on the sewage being statically treated in the sedimentation chamber 13.

[0068] It should be noted that, since the maximum level of the sewage injected into the filter chamber 11 will not be higher than the setting height of the sewage outlet 9, only when the top height of the second partition 14 is lower than the setting height of the sewage outlet 9 can it be ensured that the sewage entering the sedimentation chamber 13 can automatically overflow to the other side of the second partition 14 without additional interference and merge into the sewage undergoing static treatment.

[0069] Preferably, see Figure 3 and Figure 8The modular rural sewage resource utilization device of this embodiment also includes a second filter component, which includes a fixed frame 20, an activated carbon adsorption plate 21 and a mounting frame 22. A first filter plate 23 is provided in the middle position of the mounting frame 22. The fixed frame 20 is installed with an opening in the middle between the second partition plate 14 and the inner wall of the sedimentation chamber 13 away from the reaction chamber 12, and the fixed frame 20 is located above the drain pipe 7. The activated carbon adsorption plate 21 and the mounting frame 22 are stacked on the top of the fixed frame 20 from low to high. The inner walls on both sides of the sedimentation chamber 13 are respectively provided with first limit strips 25 extending along the top and bottom directions. The mounting frame 22 and the activated carbon adsorption plate 21 are slidably matched with the first limit strips 25 on the inner walls on both sides through slide grooves. The first filter plate 23 and the activated carbon adsorption plate 21 are respectively used for secondary filtration and adsorption purification of the sewage after the reaction treatment. After the secondary filtration and adsorption purification are completed, the sewage is left to settle in the sedimentation chamber 13; at the same time, the installation frame 22 and the activated carbon adsorption plate 21 are slidably matched with the first limit strips 25 on the inner walls on both sides through the slide groove, which can ensure the installation stability of each component in the second filter assembly.

[0070] Preferably, see Figure 3 and Figure 8 A fixing block 24 is respectively installed at the top position on both sides of the mounting frame 22. A groove 17 is provided on one side wall of the second partition plate 14 and the inner side wall of the precipitation chamber 13 away from the reaction chamber 12. A spring 19 and a clamping column 18 are provided in the groove 17. One end of the spring 19 abuts against the bottom of the groove 17 and the other end abuts against the clamping column 18. The protruding end of the clamping column 18 is hemispherical. A hemispherical limiting groove cooperating with the clamping column 18 is provided on the fixing block 24. The two fixing blocks 24 are respectively engaged with one clamping column 18.

[0071] See also Figure 3 and Figure 8 When the installation frame 22 is moved and placed on the top of the activated carbon adsorption plate 21, the fixing blocks 24 on both sides are respectively engaged with the hemispherical protruding ends of the clamping column 18 through their respective hemispherical limiting grooves, so as to fix the installation frame 22 and better ensure the installation stability of various components in the second filter assembly; and when the second filter assembly needs to be replaced, since the fixing block 24 and the clamping column 18 are an arc-surface matching structure, the installation frame 22 can be removed by simply pressing or pulling up the installation frame 22.

[0072] It should be noted that the spring 19 is used to provide a restoring force for the clamping column 18 , and the fixing effect of the mounting frame 22 and the force required for assembly and disassembly of the mounting frame 22 are all related to the spring 19 .

[0073] Preferably, two handles are fixedly provided on the top of the installation frame 22 , so that the user can take out the installation frame 22 from the precipitation chamber 13 .

[0074] Specifically, see Figure 3 and Figure 8 When disassembling the second filter component, the user only needs to use the handle to lift the installation frame 22 to make the fixing blocks 24 on both sides break away from the limit of the card column 18, and then take out the installation frame 22 and the activated carbon adsorption plate 21 in turn; when installing the second filter component, the user needs to first slide the activated carbon adsorption plate 21 into the sedimentation chamber 13 and place it on the fixing frame 20, and then place the installation frame 22 on the activated carbon adsorption plate 21, and slightly press the installation frame 22 to make the card column 18 under the action of the spring 19. The hemispherical limit groove of the corresponding fixing block 24 is inserted, thereby completing the fixation.

[0075] Preferably, see Figure 1 The treatment box 1 is provided with an observation window 4 on one side outer wall of the filter chamber 11, so that the operator of the device can more intuitively see the water level inside the filter chamber 11, to prevent the sewage level from being higher than the sewage outlet 9 and causing sewage outflow.

[0076] This embodiment also provides a method for using the modular rural sewage resource utilization device, comprising the following steps: Figures 1 to 8 :

[0077] S1: The sewage to be treated is sent from the water inlet pipe 5 to the filter chamber 11, and the driving component is started to drive the second filter plate 28 to perform a continuous shaking lifting movement. The sewage entering the filter chamber 11 falls into the bottom of the filter chamber 11 after being filtered by the second filter plate 28 and enters the reaction chamber 12 through the connecting pipe 15, while the filtered impurities automatically move to the lower side along the second filter plate 28 to complete the cleaning and collection of the impurities, and are discharged from the sewage outlet 9 when the second filter plate 28 is raised to the limit position. The user collects the discharged impurities outside the treatment box 1 for subsequent treatment or reuse;

[0078] S2: The sewage treatment chemicals are then delivered to the reaction chamber 12 through the drug inlet pipe 6 to treat the sewage, and then the stop valve 16 is opened to allow the treated sewage in the reaction chamber 12 to enter the sedimentation chamber 13 and complete static sedimentation in the sedimentation chamber 13. Finally, the treated sewage in the sedimentation chamber 13 is discharged from the drain pipe 7 through the water pump 8 to complete the reuse of the sewage.

[0079] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
