Technical Field

[0001] The utility model relates to a rural domestic sewage filtering device, belonging to the technical field of sewage treatment. Background Art

[0002] Domestic sewage is the wastewater discharged in residents' daily life, mainly from residential buildings and public buildings. In recent years, if the sewage generated in most rural areas is directly discharged into rivers, it will not only damage the environment, but also exacerbate the contradiction of water resource shortage due to a large amount of wasted water resources. Therefore, before discharging sewage, it is necessary to use a sewage treatment device to remove and degrade harmful substances and environmentally polluting components in domestic sewage and make harmless treatment of the sewage.

[0003] Existing sewage filtering devices need to separate various solid wastes in sewage from the sewage to avoid clogging of the sewage filtering device caused by solid wastes. However, when separating various solid wastes in sewage, the filter plates in the existing sewage filtering devices will be clogged by solid wastes after a long time of use, and thus the filtering effect of the filter plates will be reduced. Content of the Utility Model

The interior of the filtering box is divided into a coarse filtering area, a fine filtering area and a transfer area by a first filter plate and a second filter plate. The bottom end of the transfer area is communicated with the treatment box through a diversion pipe, and a solenoid valve is arranged on the diversion pipe. Two operating boxes are fixed on one side of the filtering box away from the treatment box, and a swinging mechanism cooperating with the first filter plate and the second filter plate is respectively arranged in the two operating boxes.

[0007] Furthermore, the swinging mechanism includes a first fixed seat fixed on the inner bottom of the operating box and two second fixed seats fixed on the inner side wall of the operating box. A first motor is arranged at the bottom end of the first fixed seat, and the output end of the first motor penetrates to the outside of the first fixed seat and is connected with a first conical half gear. A rotating rod is rotatably connected to the two second fixed seats. A second conical half gear and a third conical half gear are respectively fixed between the two second fixed seats at both ends of the rotating rod, and the second conical half gear and the third conical half gear are respectively meshed with the first conical half gear.

[0008] Further, one end of each of the two rotating rods penetrates to the outside of the operation box and is connected with a connecting rod, and the ends of the two connecting rods penetrate into the filter box and extend into the middle parts of the first filter plate and the second filter plate and are fixedly connected with the first filter plate and the second filter plate.

[0009] Further, a plurality of fixing blocks are symmetrically arranged on the inner walls of both sides of the filter box, a rubber pad is arranged on each of the left and right sides of each fixing block, and the first filter plate and the second filter plate are respectively in contact with the fixing blocks.

[0010] Further, an activity groove is respectively formed in the inner walls of both sides of the filter box, and the ends of the first filter plate and the second filter plate are movably connected in the activity grooves.

[0011] Further, a filter net is arranged at the inner bottom of the filter box, through holes matched with the first filter plate and the second filter plate are formed in the filter net, and a pull rod is arranged on each of the two sides of the top of the filter net.

[0012] Further, two rubber partitions are arranged on each of the two sides of the bottom ends of the first filter plate and the second filter plate, a plurality of filter holes are formed in the surfaces of the rubber partitions, the bottom ends of the rubber partitions are in contact with the inner bottom of the filter box, and a spring is connected between the middle parts of the bottom ends of the first filter plate and the second filter plate and the inner bottom of the filter box.

[0013] The beneficial effects of the utility model are as follows:

Two operation boxes 7 are fixed on one side of the filter box 2 away from the treatment box 3. Swing mechanisms that cooperate with both the first filter plate 5 and the second filter plate 6 are respectively provided in the two operation boxes 7. Through the arrangement of the first filter plate 5 and the second filter plate 6, sewage and solid waste enter the coarse filtration area 17 together. The sewage will flow through the mesh holes on the first filter plate 5 and the second filter plate 6 into the fine filtration area 18 and the transfer area 19. The solid waste in the sewage will be intercepted by the first filter plate 5 in the coarse filtration area 17. The solid waste smaller than the mesh holes of the first filter plate 5 will enter the fine filtration area 18 through the first filter plate 5 and be intercepted by the second filter plate 6. At this time, there is basically no solid waste in the sewage located in the transfer area 19, so as to achieve the effect of solid-liquid separation of solid waste and sewage.

[0029] Refer to Figure 3 , Figure 4, the swing mechanism includes a first fixed seat 8 fixed to the inner bottom of the operation box 7 and two second fixed seats 9 fixed to the inner side wall of the operation box 7. A first motor 10 is provided at the bottom end of the first fixed seat 8. The output end of the first motor 10 penetrates to the outside of the first fixed seat 8 and is connected to a first conical half gear 11. A rotating rod 12 is rotatably connected to the two second fixed seats 9. A second conical half gear 13 and a third conical half gear 14 are respectively fixed between the two ends of the rotating rod 12 and between the two second fixed seats 9. The second conical half gear 13 and the third conical half gear 14 are respectively meshed with the first conical half gear 11. One ends of the two rotating rods 12 respectively penetrate to the outside of the operation box 7 and are connected with connecting rods 15. The ends of the two connecting rods 15 both penetrate into the filter box 2 and extend into the middle parts of the first filter plate 5 and the second filter plate 6 and are fixedly connected to the first filter plate 5 and the second filter plate 6. Through the setting of the swing mechanism, when there is a lot of debris accumulated on the first filter plate 5 and the second filter plate 6, after the sewage in the filter box 2 is discharged, the swing mechanism can be started to drive the first filter plate 5 and the second filter plate 6 to swing in the filter box 2. While the first filter plate 5 and the second filter plate 6 are swinging, the two ends of the first filter plate 5 and the second filter plate 6 will repeatedly impact on the fixed blocks 16, so that the solid garbage on the first filter plate 5 and the second filter plate 6 can be detached.

[0030] Refer to Figure 1 , Figure 2 , Figure 3 , a number of fixed blocks 16 are symmetrically arranged on the inner side walls of both sides of the filter box 2. A rubber pad is respectively arranged on the left and right sides of the fixed block 16. The first filter plate 5 and the second filter plate 6 are respectively in contact with the fixed block 16. An activity groove 20 is respectively opened on the inner side walls of both sides of the filter box 2. The ends of the first filter plate 5 and the second filter plate 6 are both movably connected in the activity groove 20. Through the setting of the rubber pad, the rubber pad is located on both sides of the fixed block 16. When the first filter plate 5 and the second filter plate 6 impact on the fixed block 16, the rubber pad can buffer and protect the first filter plate 5 and the second filter plate 6 to avoid damage caused by repeated impacts and affect the filtering effect.

[0031] Refer to Figure 2 and Figure 5, a filter screen 23 is provided at the inner bottom of the filter box 2. Through holes 24 that cooperate with both the first filter plate 5 and the second filter plate 6 are formed in the filter screen 23. At both sides of the top of the filter screen 23, a pull rod 25 is provided respectively. Through the arrangement of the filter screen 23, driven by the swing mechanism, the first filter plate 5 and the second filter plate 6 swing, and then can strike the fixing block 16, so that the sundries on the swing mechanism can be cleaned off and fall onto the filter screen 23 at the inner bottom of the filter box 2. When it is necessary to clean the solid garbage on the filter screen 23, the filter screen 23 is lifted upward to the middle of the filter box 2, and then the garbage on the surface of the filter screen 23 can be cleaned.

[0032] Refer to Figure 6 , at both sides of the bottom ends of both the first filter plate 5 and the second filter plate 6, two rubber partitions 21 are provided. A plurality of filter holes are formed in the surface of the rubber partition 21. The bottom end of the rubber partition 21 is in contact with the inner bottom of the filter box 2. Between the middle of the bottom ends of both the first filter plate 5 and the second filter plate 6 and the inner bottom of the filter box 2, a spring 22 is connected. Through the arrangement of the rubber partition 21 and the spring 22, the rubber partition 21 is arranged at both sides of the first filter plate 5 and the second filter plate 6, and a plurality of filter holes are formed in the surface of the rubber partition 21, and the filter holes can enable the sewage to pass through smoothly.

[0033] During use, the sewage and solid garbage enter the coarse filtration area 17 together. Since the first filter plate 5 and the second filter plate 6 are provided in the filter box 2, the sewage will flow through the mesh holes on the first filter plate 5 and the second filter plate 6 into the fine filtration area 18 and the transfer area 19. The solid garbage in the sewage will be intercepted by the first filter plate 5 in the coarse filtration area 17. The solid garbage smaller than the mesh holes of the first filter plate 5 will enter the fine filtration area 18 through the first filter plate 5 and be intercepted by the second filter plate 6 in the fine filtration area 18. At this time, there is basically no solid garbage in the sewage in the transfer area 19. Subsequently, the solenoid valve on the diversion pipe 4 is started, and the sewage in the transfer area 19 flows into the treatment box 3 through the diversion pipe 4, which is convenient for its treatment;

[0034] When there is a lot of debris accumulated on the first filter plate 5 and the second filter plate 6, after the sewage in the filter tank 2 is drained, the swing mechanism can be started to drive the first filter plate 5 and the second filter plate 6 to swing in the filter tank 2. While the first filter plate 5 and the second filter plate 6 are swinging, both ends of the first filter plate 5 and the second filter plate 6 will repeatedly impact on the fixed block 16, thereby cleaning the solid waste on the first filter plate 5 and the second filter plate 6. That is, start the motor 10, the motor 10 drives the first conical gear 11 to rotate. The first conical gear 11 is previously engaged with the second conical gear 13, thereby driving the second conical gear 13 to rotate clockwise. The second conical gear 13 drives the rotating rod 12 to rotate clockwise. When the rotating rod 12 rotates clockwise, it will drive the connecting rod 15, the first filter plate 5 and the second filter plate 6 to rotate clockwise. At this time, one end of the first filter plate 5 and the second filter plate 6 will gradually rotate until it impacts on the fixed block 16 on one side. At this time, the third conical gear 14 is not engaged with the first conical gear 11, and the third conical gear 14 idles. When the first conical gear 11 continues to rotate and gradually disengages from the second conical gear 13 and engages with the third conical gear 14, at this time, the rotation of the first conical gear 11 will drive the third conical gear 14 to rotate counterclockwise. The rotating rod 12 driven by the third conical gear 14 rotates counterclockwise synchronously. At this time, the second conical gear 13 idles. When the rotating rod 12 rotates counterclockwise, it will drive the connecting rod 15, the first filter plate 5 and the second filter plate 6 to rotate counterclockwise. At this time, the ends of the first filter plate 5 and the second filter plate 6 rotate in the reverse direction and gradually impact on the fixed block 16 on the other side. Under the repeated rotation of the connecting rod 15, it will drive the first filter plate 5 and the second filter plate 6 to swing repeatedly, thereby being able to repeatedly contact the fixed block 16. With the continuous swinging and impact of the first filter plate 5 and the second filter plate 6, the debris on the first filter plate 5 and the second filter plate 6 can be cleaned and dropped onto the filter screen 23 at the bottom of the filter tank 2;

[0035] When it is necessary to clean the solid waste on the filter screen 23, lift the pull rod 25 upward to drive the filter screen 23 to move upward, and lift the filter screen 23 to the middle of the filter tank 2, then the garbage on the surface of the filter screen 23 can be cleaned.

[0036] Although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
