DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0040] like Figure 1-Figure 5 As shown, it is a structural diagram of a sewage treatment device with multiple purification functions provided by an embodiment of the present invention, comprising a treatment box 1, a bottom cover 7, a scraper and impurity removal mechanism 100, a periodic discharge mechanism 200, a filter layer, a two-way mixing mechanism 300 and an elastic quick release mechanism 400, wherein the scraper and impurity removal mechanism 100 is arranged at the top of the treatment box 1, and filters and removes impurities from the sewage entering the treatment box 1; the periodic discharge mechanism 200 is arranged inside the rotating shaft 4 in the scraper and impurity removal mechanism 100, and discharges impurities outward when opened; the filter layer is arranged in the middle of the treatment box 1, and is used to filter the mixed sewage; the two-way mixing mechanism 300 is rotatably installed on the treatment box 1, and the two-way mixing mechanism 300 is transmission-connected with the rotating shaft 4, so as to fully stir the sewage and the added agent; the elastic quick release mechanism 400 is installed on the treatment box 1 and the bottom cover 7, and the closing or opening action of the treatment box 1 and the bottom cover 7 is achieved by adjusting the position of the free end of the elastic quick release mechanism 400.

[0041] In one example of the present invention, a water injection pipe can be added to the treatment box 1 as needed to add sewage into the treatment box 1. In addition, a medicine storage box should be arranged on the outside of the treatment box 1 to add reagents to the space between the sieve plate 2 3 and the filter layer 1 17. At the same time, the bottom end of the treatment box 1 is also connected to a drain pipe 31 for discharging the treated water to the outside.

[0042] like Figure 1As shown, as a preferred embodiment of the present invention, the scraping and impurity removing mechanism 100 includes a sieve plate 1 2, a sieve plate 2 3, a rotating shaft 4, a scraping rod 5 and a telescopic member 16;

[0043] The sieve plate 1 2 and the sieve plate 2 3 are fixedly mounted on the inner wall of the processing box 1, and sieve holes are formed on the sieve plate 1 2 and the sieve plate 2 3, and the hole diameter of the sieve plate 1 2 is larger than the hole diameter of the sieve plate 2 3;

[0044] The rotating shaft 4 is rotatably mounted on the processing box 1, and the rotating shaft 4 is driven by a driving motor 6 external to the processing box 1;

[0045] Two scraping rods 5 are fixedly mounted on the rotating shaft 4 , one scraping rod 5 abuts against the sieve plate 1 2 , and the other scraping rod 5 abuts against the sieve plate 2 3 .

[0046] In one example of the present invention, sewage passes through sieve plate 1 2 and sieve plate 2 3 in sequence when moving downward, and large particles of debris in the sewage are intercepted by the arranged sieve plates 1 2 and 2 3. At the same time, the driving motor 6 drives the rotating shaft 4 to rotate along the treatment box 1 when working, and the rotating shaft 4 drives the scraper rod 5 to rotate along the sieve plates 1 2 and 2 3. The scraper rod 5 scrapes off the debris attached to the sieve plates 1 2 and 2 3 to prevent the debris from clogging the sieve holes.

[0047] like Figure 1 and Figure 2 As shown, as another preferred embodiment of the present invention, the periodic discharge mechanism 200 includes a guide hole 8, a gasket 9, a collection shell 14 and a discharge hole 15;

[0048] The outlet hole 8 is provided on the bottom cover 7 and communicates with the space inside the rotating shaft 4, and a gasket 9 is also installed in the outlet hole 8;

[0049] The collecting shell 14 is installed at the bottom end of the bottom cover 7 and arranged corresponding to the outlet hole 8 , and a discharge hole 15 is opened on the side of the collecting shell 14 .

[0050] In one embodiment of the present invention, when the rotating shaft 4 is connected, the water-containing debris moves along the inner cavity of the rotating shaft 4 under the action of gravity, passes through the outlet hole 8 and falls into the collecting shell 14, and is finally discharged outward through the discharge hole 15 arranged on the side.

[0051] like Figure 1 , Figure 2 and Figure 3 As shown, as another preferred embodiment of the present invention, the periodic discharging mechanism 200 further includes a guide rod 10, a connecting rod 11, a sealing block 12, a limiting groove 13 and a telescopic member 16;

[0052] The guide rod 10 is slidably mounted in the rotating shaft 4, and the guide rod 10 is driven by a telescopic member 16 mounted on the collecting shell 14;

[0053] Connecting rods 11 are hinged on both sides of the guide rod 10 . The connecting rod 11 is hinged to a sealing block 12 mounted on the rotating shaft 4 , and a limiting groove 13 is provided on the inner side of the rotating shaft 4 for the sealing block 12 to move.

[0054] In one example of the present invention, the telescopic member 16 described in the present application selects linear drive devices such as air cylinders, hydraulic cylinders, electric cylinders and electric telescopic rods. When the telescopic member 16 is working, it pulls the guide rod 10 to move. On the one hand, the guide rod 10 drives the gasket 9 to disengage from the outlet hole 8. On the other hand, the guide rod 10 pushes the connecting rod 11 to move, so that the sealing block 12 moves along the limiting groove 13 to ensure that the debris on the sieve plate 1 2 and the sieve plate 2 3 can pass through the holes on the side of the rotating shaft 4 into the rotating shaft 4 and move downward through the outlet hole 8.

[0055] like Figure 1 As shown, as another preferred embodiment of the present invention, the filter layer includes a filter layer 17, a filter layer 2 18 and a filter layer 3 19;

[0056] The filter layer 1 17, the filter layer 2 18 and the filter layer 3 19 are arranged from top to bottom, and a drainage pipe 31 is connected to the bottom of the filter layer 3 19 on the side of the treatment box 1;

[0057] The filtering accuracies of the filtering layer 1 17 , the filtering layer 2 18 and the filtering layer 3 18 are successively improved so as to improve the purity of the filtered water flow.

[0058] In one example of the present invention, the filter layer 1 17, the filter layer 2 18 and the filter layer 3 19 can be processed with quartz sand, activated carbon and the like as raw materials when actually used, so as to facilitate graded filtration when the water flows downward step by step.

[0059] like Figure 1 and Figure 4 As shown, as another preferred embodiment of the present invention, the bidirectional mixing mechanism 300 includes a driving screw 20, a bevel gear set 21, a movable block 22, a stirring shaft 23, a stirring rod 24, a spur gear portion 25 and a driven gear 26;

[0060] The driving screw 20 is rotatably mounted on the processing box 1, and the driving screw 20 is transmission-connected to the rotating shaft 4 through the bevel gear set 21;

[0061] The driving screw 20 is provided with a movable block 22, a stirring shaft 23 is rotatably provided at the bottom of the movable block 22, and a plurality of stirring rods 24 are arranged on the stirring shaft 23;

[0062] A driven gear 26 is also installed at the bottom end of the stirring shaft 23 , and the driven gear 26 meshes with the spur gear portion 25 arranged on the filter layer to drive the stirring shaft 23 to rotate along the movable block 22 .

[0063] In one example of the present invention, when the rotating shaft 4 rotates, it drives the driving screws 20 on both sides to rotate along the processing box 1 through the bevel gear set 21. The driving screws 20 push the movable block 22 to move in the horizontal direction. The movable block 22 pushes the stirring shaft 23, the stirring rod 24 and the driven gear 26 to move in the horizontal direction. Since the driven gear 26 is engaged with the spur gear portion 25, it can rotate when the stirring shaft 23 and the stirring rod 24 move, so as to fully stir the water flow and the medicine; in addition, the two-way mixing mechanism 300 is arranged at equal angles in the radial direction of the rotating shaft 4, and the number of its arrangements can be adjusted as needed.

[0064] like Figure 1 and Figure 5 As shown, as another preferred embodiment of the present invention, the elastic quick release mechanism 400 includes a limiting rod 27, a limiting column 28, a positioning column 29 and an elastic support member 30;

[0065] The limiting rod 27 is rotatably mounted on the bottom of the processing box 1, and a limiting column 28 is installed on the free end of the limiting rod 27, and the limiting column 28 is slidably connected with the arc groove opened on the bottom cover 7;

[0066] Positioning posts 29 are symmetrically mounted on the bottom cover 7 . The positioning posts 29 are slidably connected to the processing box 1 . An elastic supporting member 30 is sleeved on the positioning posts 29 .

[0067] In one embodiment of the present invention, a sealing ring can be arranged between the processing box 1 and the bottom cover 7 as needed to improve the sealing performance of the device. Figure 1 When the filter layer 1 17, the filter layer 2 18 and the filter layer 3 19 are in the filter box, the limit rod 27 is pushed outward, and the limit rod 27 drives the limit column 28 to slide along the arc groove provided on the bottom cover 7. After the limit column 28 is separated from the bottom cover 7, the bottom cover 7 and the positioning column 29 pop outward under the action of the elastic support member 30. In this state, the bottom cover 7 is separated from the processing box 1. After the internal parts are replaced, the process is reversed to re-install the bottom cover 7 tightly on the processing box 1.

[0068] In summary, after the components are sequentially installed inside the treatment box 1, the positioning column 29 on the bottom cover 7 is aligned with the hole on the treatment box 1, and the bottom cover 7 is pressed. The elastic support member 30 is compressed by force and fluctuates inwardly to the limit rod 27. The limit column 28 slides along the arc groove provided on the bottom cover 7, thereby fixing the bottom cover 7 on the treatment box 1. The sewage enters the treatment box 1 along the external water injection pipe. When the sewage moves downward, it passes through the sieve plate 1 2 and the sieve plate 2 3 in sequence. The large particles of debris in the sewage are intercepted by the arranged sieve plates 1 2 and 2 3. At the same time, the drive motor 6 is in the working state. Under the condition, the rotating shaft 4 is driven to rotate along the processing box 1, and the rotating shaft 4 drives the scraper 5 to rotate along the sieve plate 1 2 and the sieve plate 2 3. The scraper 5 scrapes the debris attached to the sieve plate 1 2 and the sieve plate 2 3, and the water flow after filtering the large particles of debris falls on the filter layer 1 17. The external medicine storage box adds medicine to the inside. When the rotating shaft 4 rotates, the driving screws 20 on both sides are driven by the bevel gear set 21 to rotate along the processing box 1. The driving screw 20 drives the movable block 22 to move in the horizontal direction. The movable block 22 drives the stirring shaft 23, the stirring rod 24 and the driven gear 26 to move in the horizontal direction. , and because the driven gear 26 is meshed with the spur gear portion 25, it can rotate when the stirring shaft 23 and the stirring rod 24 move, so as to fully stir the water flow and the medicine. The water flow mixed with the medicine passes through the filter layer 1 17, the filter layer 2 18 and the filter layer 3 19 downward in turn for filtration, and the filtered water flow is discharged downward along the drain pipe 31. When a single filtration is completed, the telescopic member 16 pulls the guide rod 10 to move when working. On the one hand, the guide rod 10 drives the gasket 9 to disengage from the outlet hole 8, and on the other hand, the guide rod 10 pushes the connecting rod 11 to move, so that the sealing block 12 moves along the limiting groove 13 to ensure that the debris on the sieve plate 1 2 and the sieve plate 2 3 can enter the rotating shaft 4 through the hole on the side of the rotating shaft 4, and move downward through the outlet hole 8, and finally pass through the discharge hole 15 to be discharged outward; the device has the characteristics of high purification effect. While intercepting large-volume particles during the purification process, blockage can be avoided, and the debris can be discharged outward regularly. The reagent and the water flow can be stirred more fully in a short time, which greatly improves the mixing efficiency. At the same time, the processing box 1 and the bottom cover 7 can be quickly disassembled, which is convenient for completing the maintenance of internal parts in a short time.

[0069] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

[0070] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
