The embodiments of the present invention will be described in detail below with reference to Figures 1-11, but the present invention can be implemented in many different ways as defined and covered by the claims.

The embodiment of the present application discloses a wastewater recycling and reusing device. It is explained that the wastewater recycling and reusing device is mainly used in the process of recycling and reusing domestic wastewater. In terms of technical effect, it can recycle domestic wastewater twice. Filtration processing is used to filter out impurities in the water, during which organic matter and odorous substances in the water can be removed. Especially during the filtration process, the filter plate 3 can be dredged during the process of filtering out impurities in the wastewater, thereby avoiding The filter holes are clogged, which affects the filtration efficiency, and impurities can be collected and filtered again to filter out impurities with smaller diameters in the water, thereby further enhancing the filtration effect of wastewater; further, this wastewater recycling device It can also disinfect and purify the filtered water to kill bacteria, viruses and other pathogens to ensure the safety of water quality.

A sterilization unit 8 is also installed on the inner wall of the recovery cylinder 1 .

In practical applications, firstly, the wastewater is poured into the recovery cylinder 1 through the water inlet 2, and then the wastewater is filtered twice through the filter plate 3 and the reinforced filter plate 4 in order to filter out impurities, organic matter and odorous substances in the water. , and then the wastewater is disinfected and purified through the disinfection unit 8, thereby disinfecting the filtered water to kill bacteria, viruses and other pathogens and ensure the safety of water quality.

Continuing to refer to Figure 2, the filter plate 3 can only filter impurities in the water, and it is difficult to remove organic matter and odorous substances in the water. Based on this, in this embodiment, the reinforced filter plate 4 is composed of a circular frame 41 and an activated carbon filter plate. 42, wherein the circular frame 41 is installed on the inner wall of the recycling barrel 1 and is located below the filter plate 3. The circular frame 41 is provided with a plurality of water holes, and a cavity is provided inside the circular frame 41. Inside the cavity An activated carbon filter plate 42 is provided.

During the specific implementation process, the water filtered by the filter plate 3 flows downward and passes through the activated carbon filter plate 42. The activated carbon filter plate 42 can absorb organic matter and odor substances in the water to ensure the filtration effect of waste water.

Referring to Figures 2 and 3, since the wastewater contains a large amount of impurities, when the wastewater is filtered through the filter plate 3, it is easy for the impurities to block the filter holes, thereby affecting the filtration efficiency of the wastewater; in order to avoid this To solve the problem, in this embodiment, a plurality of fixed rods 5 distributed annularly and located between the filter plate 3 and the reinforced filter plate 4 are evenly arranged on the inner wall of the recycling cylinder 1. The plurality of fixed rods 5 are close to the axis of the recycling cylinder 1. One end of the two sides is jointly provided with a supporting bracket 6, and a bidirectional motor 7 is provided in the middle of the supporting bracket 6 through the motor base. The output shaft of the upper end of the bidirectional motor 7 is connected to the lower end of the filter plate 3.

Furthermore, in this embodiment, the filter plate 3 is in the shape of a cone-shaped cylinder with a diameter that gradually increases from top to bottom. When the waste water is poured into the upper end of the filter plate 3, the waste water can be discharged through the conical-cylindrical filter plate 3. The impurities in the filter roll down in turn, thereby increasing the use area of the filter plate 3, which can effectively prevent impurities from stacking, thereby improving the filtration efficiency of wastewater; a horizontally arranged annular plate 31 is installed on the outer edge of the filter plate 3 , there is a rotational fit between the annular plate 31 and the inner wall of the recycling cylinder 1, and the output shaft at the upper end of the two-way motor 7 is connected to the filter plate 3 through a telescopic shaft. The inner wall of the recycling cylinder 1 is provided with two annular positioning plates symmetrically up and down along the annular plate 31 32; The output shaft at the upper end of the bidirectional motor 7 can drive the filter plate 3 to rotate and perform preliminary filtration of the waste water.

Furthermore, in this embodiment, a plurality of annularly distributed extrusion spring rods 33 are evenly arranged between the bottom of the upper annular positioning plate 32 and the annular plate 31, and the extrusion spring rods 33 are rotationally connected to the annular plate 31, so that The rotation of the annular plate 31 is not affected. A plurality of annularly distributed and staggered resistance blocks 34 are provided between the annular plate 31 and the lower annular positioning plate 32; the extrusion spring rod 33 always exerts a downward force on the annular plate 31. The extrusion force of the moving trend causes the annular plate 31 to drive the filter plate 3 downward to the lowest position in the initial state.

Further, in this embodiment, a plurality of annularly distributed vertical rods 61 are installed on the supporting bracket 6. A plurality of dredge posts 63 corresponding to the positions of the filter holes are installed on the upper ends of the vertical rods 61 through the top plate 62.

During the specific implementation process, the bidirectional motor 7 is started, and the output shaft at the upper end of the bidirectional motor 7 drives the filter plate 3 to rotate, and the filter plate 3 drives the resistance block 34 at the bottom thereof to rotate circumferentially as a whole through the annular plate 31; when the resistance block 34 between the annular plate 31 and the annular positioning plate 32 below it conflicts with each other, the annular plate 31 is controlled to drive the filter plate 3 to move upward, and then the annular plate 31 drives the filter plate 3 to move downward and reset under the action of the extrusion spring rod 33 and controls the resistance block 34 to collide, so as to realize the up and down reciprocating movement of the filter plate 3 during the rotation process, during which the filter plate 3 can vibrate under the impact of the resistance block 34, thereby accelerating the rolling speed of impurities at the upper end of the filter plate 3.

At the same time, when the filter plate 3 moves up, it is located above the dredging column 63. When the filter plate 3 moves down, the dredging column 63 passes through the filter hole, so that the impurities remaining in the filter hole can be poked out to the upper end of the filter plate 3, thereby avoiding clogging of the filter hole and affecting the filtration efficiency, and can effectively prevent impurities from passing through the filter hole and falling into the water, thereby achieving separation between water and impurities.

Referring to Figures 3, 4 and 5, since the filtered impurities accumulate on the upper end of the filter plate 3 and easily block the filter holes, the impurities need to be discharged regularly. Based on this, in this embodiment, the filter plate 3 is close to the annular plate A plurality of annularly distributed through holes 35 are evenly provided on one side of the filter plate 3. An annular guide plate 37 is installed at the lower end of the filter plate 3 through an annular telescopic plate 36. The annular guide plate 37 is provided with water holes. The annular telescopic plate 36 and the through holes 35 The side wall close to the axis of the recycling cylinder 1 is flush; in this embodiment, a collection area for collecting impurities can be formed between the annular telescopic plate 36, the annular guide plate 37 and the recycling cylinder 1, thereby preventing impurities from accumulating in the filter. The upper end of plate 3.

Through the arrangement of the torsion spring, the water baffle 301 always has the ability to move closer to the recovery tube 1 The tendency of one side of the axis to rotate, so that the water baffle 301 remains vertical in the initial state and blocks the discharge port 39 to prevent the water inside the recovery tube 1 from flowing out; the outer wall of the recovery tube 1 is evenly provided with multiple discharge holes The supporting plate 302 is corresponding to the position of the material opening 39 and located below it. The upper end of the supporting plate 302 is equipped with a guide post 303. The outer walls of the multiple guide posts 303 are jointly covered with an annular pressure plate 304. The upper end of the annular pressure plate 304 is equipped with a plurality of The drawstring 305 is connected to the water baffle 301.

During the specific implementation process, the filter plate 3 drives the annular guide plate 37 to rotate synchronously through the annular telescopic plate 36. During this period, the impurities at the upper end of the filter plate 3 fall into the collection area through the through holes 35 and accumulate on the upper end of the annular guide plate 37. Through the annular The guide plate 37 can further filter impurities to filter out impurities with smaller diameters in the waste water, and the filtered water flows downward through the water holes.

When a certain amount of impurities are collected in the collection area, the annular pressure plate 304 is pressed downward, and the annular pressure plate 304 drives the water baffle plate 301 to rotate to the side away from the axis of the recovery tube 1 through the pull rope 305 and opens the discharge port 39. At the same time, the filter plate 3 always drives the annular guide plate 37 to rotate through the annular telescopic plate 36, and the support rod and the material-moving rod 38 are in a fixed state. Therefore, there is a relative circumferential movement between the annular guide plate 37 and the material-moving rod 38. When the annular guide plate 37 drives the impurities at its upper end to rotate to the discharge port 39, the impurities can be moved to the discharge port 39 and discharged to the outside of the recovery tube 1 under the action of the material-moving rod 38, so that the impurities in the recovery tube 1 can be discharged at any time, avoiding the accumulation of impurities at the upper end of the filter plate 3 to cause the filter holes to be blocked and affect the filtering effect of the wastewater.

Then the downward pressure on the annular pressure plate 304 is released. At this time, the water blocking plate 301 is reset under the action of the torsion spring and the pull rope 305 drives the annular pressure plate 304 to move upward and reset.

Referring to Figures 4 and 6, since the wastewater can only be filtered once through the filter plate 3, there may be impurities with smaller diameters in the filtered wastewater. Based on this, in this embodiment, the wastewater can also be guided to The upper end of the annular guide plate 37 is filtered again; specifically, the outer wall of the output shaft at the upper end of the two-way motor 7 is covered with an annular frame 71 located below the filter plate 3.

During the specific implementation process, when the hollow shaft 89 drives the support rod 82 to rotate through the sleeve 81, the support rod 82 rotates under the action of the gear 100 and the positioning tooth 99, so that the support rod 82 revolves along the hollow shaft 89 while driving the stirring plate 84 and the extension plate 85 to rotate, thereby increasing the mixing speed of the disinfectant and water, so as to enhance the disinfection effect on water.

In addition, the present invention also provides a wastewater recycling and reuse method, which includes the following steps:

S1: Wastewater recovery: First, pour the wastewater into the recycling cylinder 1 through the water inlet 2.

S2: Preliminary filtration: start the bidirectional motor 7. The bidirectional motor 7 drives the filter plate 3 to rotate. When the filter plate 3 drives the annular plate 31 to rotate, the filter plate 3 is controlled to reciprocate up and down through the cooperation between the conflict block 34 and the extruded spring rod 33. Move and generate vibration, so that the impurities at the upper end of the filter plate 3 roll down into the through hole 35 and accumulate on the upper end of the annular guide plate 37. The impurities can be further filtered through the annular guide plate 37 to facilitate the filtering of smaller diameter particles in the wastewater. Impurities, filtered water flows down through the water hole.

During this period, when the filter plate 3 moves downward, the dredge posts 63 pass through the filter holes, so that the impurities remaining in the filter holes can be pushed out to the upper end of the filter plate 3, thereby avoiding clogging of the filter holes.

When the impurities in the collection area are collected to a certain amount, the annular pressure plate 304 is pressed downward, and the annular pressure plate 304 drives the water baffle 301 to rotate to the side away from the axis of the recovery barrel 1 through the pull rope 305 and opens the discharge port 39; this At this time, there is relative circumferential movement between the annular guide plate 37 and the material stirring rod 38, and the impurities are moved to the discharge port 39 through the material stirring rod 38 and discharged to the outside of the recovery tube 1; then the downward pressure on the annular pressure plate 304 is released, At this time, the water blocking plate 301 is reset under the action of the torsion spring and drives the annular pressure plate 304 to move upward and reset through the pull rope 305.

In addition, the water filtered by the filter plate 3 flows downward to the upper ends of the plurality of fan-shaped plates 72. The fan-shaped plates 72 vibrate under the up and down movement of the filter plate 3 and the annular telescopic plate 36 and remove the waste water and residual impurities at their upper ends. It is discharged through the discharge chute 74 to the upper end of the annular guide plate 37, so that the annular guide plate 37 filters the waste water again to filter out impurities with smaller diameters in the waste water.

S3: Secondary filtration: The water filtered by the filter plate 3 flows downward and passes through the activated carbon filter plate 42. The activated carbon filter plate 42 can absorb organic matter and odor substances in the water to ensure the filtration effect of waste water.

S4: Disinfection: Pour the disinfectant used for wastewater disinfection into the storage cartridge 91, so that the disinfectant passes through the liquid inlet pipe 92, the storage chamber 93, the conversion hole 94, the spoiler hole 95 and the branch hole 96 and then passes through the seepage The liquid hole 97 slowly seeps out to the outside of the extension plate 85 and dissolves in the water at the bottom of the recovery tube 1; then the bidirectional motor 7 drives the support rod 82 to move circumferentially through the sleeve 81, so that the support rod 82 drives the mixing plate 84 and the extension plate 85 to pair The filtered wastewater and disinfectant in the recovery cylinder 1 are stirred so that the wastewater and the disinfectant are evenly mixed, thereby disinfecting and purifying the wastewater; then the disinfected water flows downward through the semipermeable membrane 86 to the bottom of the recovery cylinder 1 and passes through The semipermeable membrane 86 can further filter out residual particles in the water.

S5: Discharge: start the water pump 87, pump out the treated water through the water pump 87 and use it for non-drinking water purposes such as toilet flushing, irrigation, laundry, cleaning, etc., so as to realize the recycling and reuse of domestic waste water.
