[0001] The utility model relates to the technical field of sewage treatment, and particularly relates to a scum collection device suitable for municipal sewage treatment. Background Technique

[0002] In the process of municipal sewage treatment, scum in sewage such as grease and suspended substances are common pollutants. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, and energy. Therefore, it is necessary to set up a scum collection device suitable for municipal sewage treatment to collect the scum in sewage. However, the existing devices still have certain defects in use, such as:

[0003] A scum collection device for sewage treatment disclosed in the patent number "CN201920960203.3". When this device is in use, the floating structure provided on the outer side of the collection housing facilitates placement in sewage. Setting multiple such devices can achieve full coverage of the sewage surface. Using a solar water pump is more energy-saving and environmentally friendly. The filter plate is convenient for filtering and collecting the scum in sewage. However, during the use of the device, since the filter plate continuously filters the scum, when there is too much scum, the scum may accumulate at the holes of the filter plate, resulting in the problem of clogging the filter plate, and thus the problem that the device cannot continue to filter. Content of the Utility Model

[0004] The purpose of the utility model is to propose a scum collection device suitable for municipal sewage treatment to solve the above problems, and improve the problem of low filtration effect of the existing scum collection device suitable for municipal sewage treatment.

[0005] A scum collection device suitable for municipal sewage treatment includes a housing and a first waterproof housing: a first waterproof housing is arranged at the upper end of the housing, and a filtering structure is arranged inside the housing;

[0006] The filtering structure includes a motor, a threaded rod, and a filtering inclined plate. A motor is arranged inside the first waterproof housing, a threaded rod is arranged below the motor, and a filtering inclined plate is arranged on the surface of the threaded rod. The filtering inclined plate is threadedly connected to the threaded rod.

[0007] Preferably, the threaded rod penetrates through the first waterproof housing and the housing, and a water inlet is opened on the side surface of the housing.

[0008] Preferably, a water pump is arranged inside the first waterproof housing, a water outlet is arranged above the water pump, and the water outlet penetrates through the first waterproof housing.

[0009] Preferably, a collection bin is provided on the side of the outer shell, a water pipe is provided on the side of the first waterproof shell, one end of the water pipe is connected to the water pump, and the other end of the water pipe is connected to the outer shell and the collection bin.

[0010] Preferably, a floating block is provided on the side of the outer shell, a second waterproof shell is provided at the upper end of the collection bin, and a hydraulic rod is provided inside the second waterproof shell.

[0011] Preferably, a pressing plate is provided at the lower end of the hydraulic rod, the hydraulic rod penetrates through the collection bin, and a filter plate is provided inside the collection bin.

[0012] Preferably, the filter inclined plate is slidably connected to the outer shell, and the filter inclined plate is arranged with both sides inclined downward.

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

[0014] 1. Through the settings of the motor, threaded rod, and filter inclined plate, when the device is in use, first, the filter inclined plate is located at the opening of the collection bin of the outer shell and seals the collection bin. At this time, the device floats on the water surface through the floating block, and the water inlet is below the water level. Subsequently, water continuously enters the interior of the outer shell through the water inlet. At this time, the filter inclined plate filters the floating scum. When the floating scum accumulates too much, the motor is turned on at this time, so that the motor drives the threaded rod to rotate, and drives the filter inclined plate to move downward on the surface of the threaded rod, and opens the opening between the outer shell and the collection bin, so that the floating scum enters the interior of the collection bin through the angle of the filter inclined plate, so as to clean the floating scum on the surface of the filter inclined plate, to prevent the filter inclined plate from being blocked due to excessive accumulation of floating scum. In this way, not only is it prevented that the filter inclined plate is blocked and continues to filter, but also the storage capacity of the device for storing floating scum is increased, and the efficiency of the device for collecting floating scum is improved.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] During specific implementation: As Figures 1-4 shown, a scum collection device applicable to municipal sewage treatment includes an outer shell 1 and a first waterproof shell 3: A first waterproof shell 3 is provided at the upper end of the outer shell 1, and a filter structure 16 is provided inside the outer shell 1;

[0022] The filter structure 16 includes a motor 10, a threaded rod 11, and a filter inclined plate 12. A motor 10 is provided inside the first waterproof shell 3, a threaded rod 11 is provided below the motor 10, a filter inclined plate 12 is provided on the surface of the threaded rod 11, and the filter inclined plate 12 is threadedly connected to the threaded rod 11;

[0023] When the device is in use, first, both sides of the filter inclined plate 12 are located at the opening of the collection bin 2. At this time, the water inlet 4 is below the water level. Subsequently, water continuously enters the inside of the outer shell 1 through the water inlet 4 and is filtered by the filter inclined plate 12 to make the scum located on both sides of the filter inclined plate 12. At this time, when the scum accumulates too much, the motor 10 is turned on to drive the threaded rod 11 to rotate, so that the filter inclined plate 12 moves downward on the surface of the threaded rod 11, exposing the opening of the collection bin 2 and allowing the scum on both sides of the filter inclined plate 12 to enter the inside of the collection bin 2, thereby preventing the scum from accumulating on the surface of the filter inclined plate 12 and causing the filter inclined plate 12 to become blocked and unable to continue filtering.

[0024] The threaded rod 11 penetrates the first waterproof shell 3 and the outer shell 1, and a water inlet 4 is opened on the side of the outer shell 1;

[0025] A water pump 9 is provided inside the first waterproof shell 3, a water outlet 7 is provided above the water pump 9, and the water outlet 7 penetrates the first waterproof shell 3;

[0026] When the device is in use, first, the scum is filtered through the filtering structure 16, allowing the water flow to enter the interior of the outer shell 1. Subsequently, the water pump 9 is turned on, and the water pump 9 generates a current through the water pipe 8, so that the filtered water flow at the lower end inside the outer shell 1 is sucked into the interior of the water pump 9 through the water pipe 8, and the water flow is discharged from the water outlet 7 out of the interior of the outer shell 1, thereby achieving the effect of circulating and filtering the scum.

[0027] A collection bin 2 is provided on the side of the outer shell 1, a water pipe 8 is provided on the side of the first waterproof shell 3, one end of the water pipe 8 is connected to the water pump 9, and the other end of the water pipe 8 is connected to the outer shell 1 and the collection bin 2;

[0028] When the device is in use, when the filtering inclined plate 12 moves downward and opens the opening of the collection bin 2, at this time, the water flow carries the scum into the interior of the collection bin 2. At this time, the scum is filtered through the filter plate 15, allowing the water flow to enter the lower part inside the collection bin 2. At this time, the water pump 9 sucks and discharges the water flow below the interior of the collection bin 2 through the water pipe 8.

[0029] A floating block 6 is provided on the side of the outer shell 1, a second waterproof shell 5 is provided at the upper end of the collection bin 2, and a hydraulic rod 13 is provided inside the second waterproof shell 5;

[0030] When the device is in use, the device floats on the water surface through the floating blocks 6 provided around the outer shell 1, and the first waterproof shell 3 and the second waterproof shell 5 are used to waterproof the hydraulic rod 13, the motor 10, and the water pump 9 to prevent the water flow from damaging the components.

[0031] The lower end of the hydraulic rod 13 is provided with a pressing plate 14, the hydraulic rod 13 penetrates the collection bin 2, and a filter plate 15 is provided inside the collection bin 2;

[0032] The filtering inclined plate 12 is slidably connected to the outer shell 1, and the filtering inclined plate 12 is arranged with both sides inclined downward;

[0033] When the device is in use, the filtering inclined plate 12 moves downward to expose the opening of the collection bin 2. At this time, the water flow flushes the surface of the filtering inclined plate 12 into the interior of the collection bin 2. Subsequently, the filtering inclined plate 12 moves upward to block the opening of the collection bin 2. At this time, the filter plate 15 filters the scum, and the water flow inside the collection bin 2 is discharged through the water pump 9. Subsequently, the hydraulic rod 13 is opened to move downward, pushing the pressing plate 14, so that the pressing plate 14 moves downward to squeeze the scum, so as to compress the scum, reducing the occupied space of the scum and facilitating the subsequent centralized collection of the scum.

[0034] When the utility model is in use, first, the device floats on the surface of the water through the floating block 6. Subsequently, the water inlet 4 is located below the water surface, and water continuously enters the interior of the housing 1 and is filtered by the filter inclined plate 12 to filter the scum, so that the scum is located on both sides of the filter inclined plate 12. At this time, the water pump 9 is turned on, and the water pump 9 sucks the filtered water flow inside the housing 1 through the water pipe 8 and discharges it from the water outlet 7. When too much scum accumulates, the motor 10 is turned on at this time, so that the motor 10 drives the threaded rod 11 to rotate, causing the filter inclined plate 12 to move downward, exposing the opening of the collection bin 2. At this time, the water flow drives the scum into the interior of the collection bin 2, and then the filter inclined plate 12 moves upward to block the opening of the collection bin 2. At this time, the scum is filtered by the filter plate 15, and the water pump 9 discharges the filtered water flow inside the collection bin 2 through the water pipe 8, thereby not only preventing the filter inclined plate 12 from being blocked, but also increasing the collection capacity of the device for scum.

The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole, and 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.
