Description

Technical Field

[0002] Municipal wastewater treatment is essential to maintaining urban environmental sanitation and protecting human health. With the acceleration of urbanization, the amount of wastewater discharged has increased significantly, posing severe challenges to the natural water environment.

[0003] Traditional municipal sewage treatment equipment has certain limitations in terms of efficiency, maintenance cost and adaptability. Common methods such as grid filtration and grille filtration are prone to clogging when dealing with high-concentration, large-particle dirt, resulting in unstable equipment operation and frequent maintenance. Therefore, in the sewage purification process, it is crucial to pre-filter impurities (such as hair, cotton wool, sand, plastic fragments, animal dander, etc.) in the sewage to prevent these small particles from entering the purification system and causing equipment clogging.

[0004] Sewage treatment equipment in related technologies generally adopts a combination of fine grids and filters, but as the filtration continues, dirt gradually accumulates and eventually clogs the filter, forcing the sewage treatment work to be suspended. This not only increases the maintenance frequency and cost, reduces work efficiency, but may also have a negative impact on the sewage treatment effect. Summary of the invention

DETAILED DESCRIPTION

[0023] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0024] The sewage treatment equipment according to the embodiment of the present application is described below with reference to the accompanying drawings.

[0025] like Figure 1-Figure 4 As shown, the sewage treatment equipment of the embodiment of the present application may include a support frame 10, a box body 20, a first filtering mechanism 30, a second filtering mechanism 40, a first impurity removal mechanism 50, a second impurity removal mechanism 60, a cleaning mechanism 70 and a driving device 80.

[0026] The box body 20 is arranged on the support frame 10, a water inlet 21 is provided on the top wall of the box body 20, a drain pipe 22 is provided on the bottom of the box body 20, and a debris removal box 23 with an opening at the bottom is provided on one side wall of the box body 20. It should be noted that the drain pipe 22 described in this embodiment is arranged obliquely downward.

[0027] The first filter mechanism 30 and the second filter mechanism 40 are longitudinally distributed in the housing 20 in sequence, and the first impurity removal mechanism 50 is rotatably disposed in the first filter mechanism 30, wherein the first filter mechanism 30 is disposed close to the impurity removal box 23, and the first filter mechanism 30 is used to filter the primary impurities (large particle impurities) in the sewage. The second filter mechanism 40 is used to filter the secondary impurities (small particle impurities) in the sewage.

[0028] The second impurity removing mechanism 60 is rotatably disposed in the second filtering mechanism 40 , and the cleaning mechanism 70 is rotatably disposed in the impurity removing box 23 , and the cleaning mechanism 70 cooperates with the first impurity removing mechanism 50 .

[0029] The driving device 80 is disposed on the box body 20 , and the driving device 80 is connected to the first impurity removing mechanism 50 , the second impurity removing mechanism 60 and the cleaning mechanism 70 respectively.

[0030] In the embodiment of the present application, the cleaning mechanism 70 may be a brush roller.

[0031] Specifically, when sewage needs to be treated, the relevant staff first needs to connect the sewage outlet with the water inlet 21 of the box 20 through a pipeline.

[0032] At this time, the sewage entering the box 20 is first filtered by the first filter mechanism 30, and the primary impurities in the sewage are filtered out, and the sewage with the primary impurities filtered out directly enters the second filter mechanism 40. At this time, the second filter mechanism 40 filters out the secondary impurities in the sewage, and the sewage with the secondary impurities filtered out is discharged through the drain pipe 22.

[0033] When it is necessary to clean the filtered impurities, the staff can control the driving device 80 to drive the first impurity removal mechanism 50, the second impurity removal mechanism 60 and the cleaning mechanism 70 to rotate synchronously. The rotating first impurity removal mechanism 50 salvages the primary impurities filtered by the first filtering mechanism 30, and the rotating cleaning mechanism 70 cleans the salvaged primary impurities into the impurity discharge box 23 and discharges them through the impurity discharge box 23.

[0034] At the same time, the rotating second impurity removal mechanism 60 discharges the secondary impurities filtered by the second filtering mechanism 40 from the box body 20. The filtered impurities can be cleaned without stopping the machine, which can not only reduce the occurrence of blockage and failure, but also reduce the maintenance frequency and cost of the equipment, effectively ensuring the filtering efficiency of sewage.

[0035] In order to clearly explain the above embodiment, in one embodiment of the present application, as Figure 3 and Figure 4 As shown, the first filtering mechanism 30 may include a first semicircular filter screen 31 and a plurality of semicircular partitions 32 , wherein the first semicircular filter screen 31 is fixedly disposed in the box body 20 .

[0036] A plurality of semicircular partitions 32 are equidistantly arranged side by side and fixedly arranged on the inner wall of the first semicircular filter screen 31. For example, the plurality of semicircular partitions 32 can be 6, 7, 8, 9, 10, 11 semicircular partitions 32, etc. The specific number of use can be selected according to actual conditions and is not limited here.

[0037] Further, in one embodiment of the present application, Figure 3 and Figure 4 As shown, the second filtering mechanism 40 may include a second semicircular filtering screen 41 and two guide plates 42 .

[0038] Among them, the second semicircular filter screen 41 is fixedly set in the box body 20 and is located below the first semicircular filter screen 31, wherein the mesh aperture of the second semicircular filter screen 41 is smaller than the mesh aperture of the first semicircular filter screen 31, and a sewage pipe 401 connected to one end of the second semicircular filter screen 41 is provided on the outer wall of the box body 20.

[0039] In the embodiment of the present application, in order to seal the outlet end of the sewage pipe 401, a sealing cover (not shown in the figure) can also be set at the outlet end of the sewage pipe 401, and one side of the sealing cover can be pivotally connected to the sewage pipe 401 through a hinge or a pin, and the other side can be adsorbed and connected to the sewage pipe by setting a magnet block (not shown in the figure).

[0040] The two guide plates 42 are respectively located on both sides of the second semicircular filter screen 41 and are fixedly arranged in the box body 20, and the two guide plates 42 are integrally connected with the second semicircular filter screen 41, wherein one end of the guide plate 42 connected to the box body 20 is higher than the other end.

[0041] It is understandable that when sewage enters the box 20, the first semicircular filter 31 first filters the primary impurities in the sewage, and the filtered sewage flows to the bottom of the box 20 through the first semicircular filter 31. At this time, the sewage passes through the second semicircular filter 41, and the second semicircular filter 41 filters the secondary impurities in the sewage. The sewage filtered by the second semicircular filter 41 enters the bottom of the box 20 and is discharged through the drain pipe 22.

[0042] In one embodiment of the present application, Figure 3 and Figure 4 As shown, the first debris removing mechanism 50 may include two rotating disks 51 , a supporting shaft 52 and two fishing rakes 53 .

[0043] The two rotating disks 51 are respectively located on both sides of the plurality of semicircular partitions 32 and are rotatably disposed in the first semicircular filter screen 31 .

[0044] The support shaft 52 is rotatably disposed in the box body 20 , and the support shaft 52 is fixedly connected to the two turntables 51 respectively.

[0045] Two salvaging rakes 53 are fixedly disposed between the two rotating disks 51 around the supporting shaft 52 , and the rake claws of the salvaging rakes 53 and the semicircular partitions 32 are alternately distributed.

[0046] Further, in one embodiment of the present application, Figure 2 and Figure 3 As shown, the second impurity removing mechanism 60 may include a driving shaft 61 and a spiral blade 62 , wherein the driving shaft 61 is coaxial with the second semicircular filter screen 41 and is rotatably disposed in the housing 20 .

[0047] The spiral blade 62 is fixedly disposed on the driving shaft 61 , and the spiral blade 62 is in contact with the inner wall of the second semicircular filter screen 41 .

[0048] Further, in one embodiment of the present application, Figure 1 and Figure 2 As shown, the driving device 80 may include a driving mechanism 81 and two belt transmission mechanisms 82, wherein the driving mechanism 81 is arranged on the box body 20, and the output end of the driving mechanism 81 is fixedly connected to one end of the support shaft 52, and the other end of the support shaft 52 is respectively connected to the driving shaft 61 and one end of the cleaning mechanism 70 through the two belt transmission mechanisms 82.

[0049] It should be noted that the driving mechanism 81 described in this embodiment can be a driving motor, and the belt transmission mechanism 82 can be composed of two pulleys and a belt, wherein the two pulleys in one belt transmission mechanism 82 are respectively connected to one end of the support shaft 52 and one end of the cleaning mechanism 70, and the belt is sleeved on the two pulleys; the two pulleys in the other belt transmission mechanism 82 are respectively connected to one end of the drive shaft 61 and one end of the drive shaft 61, and the belt is sleeved on the two pulleys. Then, the support shaft 52, the drive shaft 61 and the cleaning mechanism 70 are connected in series through the two belt transmission mechanisms 82.

[0050] Specifically, when it is necessary to clean the impurities filtered by the first semicircular filter screen 31 and the second semicircular filter screen 41, the staff can control the driving mechanism 81 to drive the support shaft 52 to rotate, and the rotating support shaft 52 drives the driving shaft 61 and the cleaning mechanism 70 to rotate synchronously through two belt transmission mechanisms 82.

[0051] At this time, the rotating support shaft 52 drives the two rotating disks 51 to drive the two salvaging rakes 53 to rotate, and the rotating salvaging rakes 53 salvage the primary impurities filtered between any two adjacent semicircular partitions 32. When the rotating salvaging rakes 53 transport the salvaged primary impurities to the entrance of the impurity removal box 23, the rotating cleaning mechanism 70 transports the primary impurities salvaged by the salvaging rakes 53 into the impurity removal box 23 and discharges them through the bottom opening of the impurity removal box 23.

[0052] At the same time, the driving shaft 61 drives the spiral blade 62 to rotate, and the rotating spiral blade 62 transports the secondary impurities filtered on the second semicircular filter screen 41 to the sewage pipe 401 and discharges them through the outlet of the sewage pipe 401.

[0053] In summary, the sewage treatment equipment of the embodiment of the present application can clean filtered impurities without stopping, which can not only reduce the occurrence of blockages and failures, but also reduce the maintenance frequency and cost of the equipment, effectively ensuring the filtration efficiency of sewage.
