Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a sewage treatment recovery device. Background Art

[0002] Reusing wastewater or sewage after secondary treatment and deep treatment in production systems or for daily life is called sewage reuse. The scope of sewage reuse is very wide, from industrial reuse to water replenishment and domestic water use. Sewage reuse can not only effectively save and utilize limited and precious freshwater resources, but also reduce the discharge of sewage or wastewater, reduce water pollution, and alleviate the overload of urban drainage pipes, with obvious social, environmental and economic benefits.

[0003] Although there are many sewage treatment technologies, their basic principles mainly include separation, transformation and utilization. Among them, sewage separation treatment refers to the use of various technical methods to separate suspended matter or colloidal particles in sewage, so as to purify sewage or reduce pollutants in sewage to a minimum; by separating different components in sewage, different treatment methods can be used in a targeted manner to improve the overall treatment efficiency. Therefore, sewage separation is an important step in sewage treatment.

[0004] After searching, the Chinese invention patent with publication number CN108191124B discloses a sewage treatment and recovery device, including an impurity cleaning barrel, a cover plate is provided on the impurity cleaning barrel, a feed pipe and a water inlet pipe are connected to the cover plate, the feed pipe and the water inlet pipe are provided with through grooves on the opposite sides thereof, a plug plate for blocking the feed pipe and the water inlet pipe is slidably connected in the through groove, two diametrically opposite pole plates are provided on the inner wall of the impurity cleaning barrel, and a power supply connected to the pole plates is also provided, two diametrically opposite vibration plates are provided on the inner wall of the impurity cleaning barrel, arc-shaped protrusions are provided on the inner sides of the vibration plates, and the vibration plates and the inner wall of the impurity cleaning barrel are connected by springs; the bottom of the impurity cleaning barrel is located below the vibration plate and is connected to a collecting box, a connecting rod is connected to the outer side of the vibration plate, and the end of the connecting rod away from the vibration plate is respectively connected to the plug plate; a rotating drum is coaxially connected in the impurity cleaning barrel.

[0029] Example 1

[0030] Refer to the attached Figure 1-3The present application provides a sewage treatment and recovery device, including a sewage tank 1 and an impeller string 3. The impeller string 3 is commonly used in deep well pumps and is composed of multiple impellers connected in series. Each impeller has its own separate water inlet and outlet. This structure allows water to pass through the impellers multiple times, increasing the head and flow rate of the water body. The sewage tank 1 is provided with a pumping mechanism, a filtering mechanism and several cleaning mechanisms. The pumping mechanism is used for extracting and reusing sewage, the filtering mechanism is used for separating and treating sewage, and the cleaning mechanism is used for cleaning the filtering mechanism;

[0032] When the sewage is separated and treated, it can be injected into the sewage tank 1 from the feed hopper 19, and then the motor 11 is started. The motor 11 drives the impeller string 3 to rotate through the rotating shaft 10 to draw the water in the sewage tank 1 into the material barrel 2, and then transport it to the material pipe 21 through the cover shell 20 for discharge, thereby achieving the effect of extraction and reuse.

[0033] Preferably, the material barrel 2 is fixedly connected to the top inner wall of the sewage tank 1, and the top inner wall of the sewage tank 1 is rotatably connected with a rotating shaft 10 at the inner side of the material barrel 2, and a through groove is opened at the bottom end of the sewage tank 1, and the bottom end of the rotating shaft 10 extends to the outside of the sewage tank 1 at the through groove, and the impeller string 3 is key-connected to the outside of the shaft body of the rotating shaft 10 in the material barrel 2, and a rotating sealing ring is used to realize a rotating seal between the rotating shaft 10 and the sewage tank 1 at the through groove.

[0034] Preferably, a circular opening is provided in the middle of the top of the disc cover 1401, and the disc cover 1401 is fixedly connected to the material barrel 2 at the circular opening, a circular through hole is provided at the bottom end of the disc 1403, the rotating shaft 10 passes through the disc 1403 at the circular through hole, and the rotating shaft 10 and the disc 1403 achieve rotational sealing at the circular through hole by rotating the sealing ring, the disc cover 1401 and the disc 1403 are both truncated cone-shaped, and the number of spring pieces 15 located outside the disc body 1402 is several.

[0035] When the sewage enters the material barrel 2, the filter disc 14 can filter the sewage before it enters the material barrel 2, and because the disc cover 1401 and the disc plate 1403 of the filter disc 14 are both truncated cone-shaped, the external inclined surfaces of the two can prevent excessive accumulation of dirt, thereby preventing the dirt from clogging the filter disc 14 and ensuring the separation and treatment effect of the sewage;

[0036] In addition, the rotation of the rotating shaft 10 can also drive the connecting plate 18 to rotate through the collar 9, and the connecting plate 18 can drive the cleaning brush 17 and the connecting piece 16 to rotate. The rotation of the cleaning brush 17 outside the filter disc 14 can clean it in real time, thereby further avoiding the filter disc 14 from being blocked, thereby further ensuring the separation and treatment effect of sewage.

[0038] At the same time, the rotation of the connecting piece 16 can drive the spring piece 15 on its side to contact the spring piece 15 on the disc body 1402 of the filter disc 14, and as the connecting piece 16 continues to rotate, the two spring pieces 15 will squeeze each other and undergo elastic deformation, and after moving relatively to separate, they will both vibrate due to their own elastic force, thereby causing the filter disc 14 and the connecting piece 16 to vibrate. The vibration of the filter disc 14 can shake off dirt to prevent clogging, and the vibration of the connecting piece 16 can also vibrate the cleaning brush 17 through the connecting plate 18, thereby enhancing its cleaning effect on the filter disc 14 and achieving the effect of preventing the filter disc 14 from being blocked.

[0039] Preferably, a plurality of liquid outlets 101 are equidistantly provided at the top of the sewage tank 1 on the inner side of the material barrel 2, and a cover shell 20 is fixedly connected to the top of the sewage tank 1 on the outside of the liquid outlet 101, a material pipe 21 is fixedly connected to the top of the cover shell 20, a drain valve can be provided at one end of the material pipe 21 to facilitate control of water discharge, a feed port is provided on one side of the top of the sewage tank 1, and a feed hopper 19 is fixedly connected to the feed port.

The outside of the connecting sleeve 5 and the inner top of the material tank 8 are provided with threaded grooves, and the material tank 8 is threadedly connected to the outside of the connecting sleeve 5 through the threaded grooves. A number of supporting legs 13 are equidistantly fixedly connected to the outside of the bottom end of the material tank 8.

[0042] After the liquid in the sewage is pumped away, the remaining solid dirt will fall into the material tank 8 from the discharge port 102 due to its own gravity. Therefore, the material tank 8 can collect dirt. After each use period of the device, the material tank 8 can be rotated by moving the support feet 13 to remove it from the connecting sleeve 5, and the support feet 13 can be used to support the material tank 8 to facilitate the treatment of the dirt accumulated in the material tank 8.

A strip opening is provided at the top of the base 7, and the top ends of the two support rods 22 extend to the outside of the base 7 at the strip opening, and the top ends of the two support rods 22 are rotatably connected to the material tank 8.

[0046] When the material tank 8 needs to be removed, the motor 23 can be started. The motor 23 can drive the two-way threaded rod 26 to rotate so that the two threaded sleeves 25 can move simultaneously and in opposite directions in the horizontal direction. Therefore, the two threaded sleeves 25 can be controlled to move away from each other by the motor 23. At this time, the two threaded sleeves 25 can respectively pull the material tank 8 through the two support rods 22, and then adjust it to descend, so as to handle the dirt collected in the material tank 8; conversely, the material tank 8 can also be adjusted to rise to facilitate its installation.
