Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment equipment, and in particular to a sewage treatment sedimentation device. Background Technology

[0002] In daily life, wastewater is often generated, and a large amount of large particles of sediment accumulate in the wastewater.

[0003] In existing technologies, it is common to use filter plates to intercept particulate sand in sewage and separate the particulate sand from the sewage. However, particulate sand will accumulate on the filter plates, which need to be cleaned manually every time to ensure that the filter plates can filter normally. This consumes a certain amount of manual labor and increases labor costs. Utility Model Content

[0004] In view of the above problems, this utility model provides a sewage treatment sedimentation device, the purpose of which is to achieve self-cleaning of the filter cartridge and reduce manual labor.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A wastewater treatment sedimentation device is provided, comprising: a water tank; a filter cylinder having a plurality of filter holes and horizontally fixedly installed in the water tank; an inlet and an outlet, both axially located on the filter cylinder, with the inlet at a higher level than the outlet; a water supply pipe located on one side of the inlet for feeding wastewater into the filter cylinder; a rotating shaft rotatably installed inside the filter cylinder; a scraper installed along the axial direction of the filter cylinder, one end fixedly mounted on the rotating shaft and the other end slidably contacting the inner wall of the filter cylinder for hanging and transporting granular sediment; a drive motor for driving the rotating shaft to rotate; and a discharge assembly located on one side of the discharge outlet for receiving and transporting granular sediment.

[0007] Furthermore, the device also includes: a water supply trough located below the water supply pipe and extending toward the feed inlet; and a baffle plate located at a fixed distance from the bottom of the water supply trough, inside the water supply trough, at one end of the water supply pipe.

[0008] Furthermore, the device also includes two end caps, which are respectively installed at both ends of the filter cylinder, and the end caps are fixed to the inner wall of the water tank by support rods.

[0009] Furthermore, four scrapers are arranged in a circular array on a rotating shaft.

[0010] Furthermore, the discharge component is a U-shaped screw conveyor with an opening at the top for the particles and sand to fall into; one end of the U-shaped screw conveyor extends parallel to the axial direction of the filter cylinder into the water tank, and the screw auger built into the U-shaped screw conveyor is used to hang and transport the particles and sand.

[0011] Furthermore, the shaft of the U-shaped screw conveyor is connected by a belt drive.

[0012] The beneficial effects of this utility model are as follows: by using this utility model, the cleaning of the inner wall of the filter cylinder can be completed automatically, preventing particles and sand from accumulating inside the filter cylinder, ensuring that the filter cylinder can continuously intercept and filter particles and sand from sewage, reducing the amount of manual cleaning of the filter cylinder, and effectively reducing labor costs.

[0016] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0017] Reference Figure 1 and Figure 2 As shown in the embodiment of this application, a wastewater treatment sedimentation device is disclosed, comprising: a water tank 1; a filter cylinder 2, which has a plurality of filter holes and is horizontally fixed in the water tank 1; an inlet 21 and an outlet 22, both axially opened on the filter cylinder 2, with the inlet 21 being higher than the outlet 22; a water supply pipe 3, located on one side of the inlet 21, for feeding wastewater into the filter cylinder 2; a rotating shaft 23, rotatably disposed inside the filter cylinder 2; a scraper 24, installed along the axial direction of the filter cylinder 2, with one end fixedly disposed on the rotating shaft 23 and the other end slidably contacting the inner wall of the filter cylinder 2, for hanging and transporting granular sediment; a drive motor 25, for driving the rotating shaft 23 to rotate; and a discharge assembly, disposed on one side of the outlet 22, for receiving and transporting granular sediment.

[0018] In practical use, sewage is fed into the filter cylinder 2 through the water supply pipe 3. The filter holes in the filter cylinder 2 allow the sewage to pass through, while the particles and sand in the sewage are intercepted inside the filter cylinder 2. The drive motor 25 starts intermittently, and the drive motor 25 drives the rotating shaft 23 to rotate, which in turn drives the scraper 24 to rotate. The scraper 24 scrapes the particles and sand intercepted in the filter cylinder 2 toward the discharge port 22. Under the action of gravity, the particles and sand fall into the discharge assembly, which then transfers the particles and sand.

[0019] By using this utility model, the cleaning of the inner wall of the filter cylinder 2 can be completed automatically, preventing the accumulation of particles and sand inside the filter cylinder 2, ensuring that the filter cylinder 2 can continuously intercept and filter particles and sand from sewage, reducing the amount of manual cleaning of the filter cylinder 2, and effectively reducing labor costs.

[0020] Preferably, both the filter cartridge 2 and the scraper 24 can be made of stainless steel.

[0021] Specifically, the device also includes: a water supply trough 31, located below the water supply pipe 3 and extending toward the feed inlet 21; and a baffle 32, located at a fixed distance from the bottom surface of the water supply trough 31, inside the water supply trough 31, at one end of the water supply pipe 3.

[0022] In this embodiment, the baffle 32 is arranged parallel to the axial direction of the filter cylinder 2. The baffle 32 disperses the sewage transported by the water supply pipe 3 along the axial direction of the filter cylinder 2, thereby improving the uniformity of the sewage being fed into the filter cylinder 2 along the axial direction.

[0023] Preferably, the device further includes two end caps 26, which are respectively disposed at both ends of the filter cylinder 2, and the end caps 26 are fixedly disposed on the inner wall surface of the water tank 1 by means of support rods.

[0024] In this embodiment, four scrapers 24 are arranged in a circumferential array on a rotating shaft 23.

[0025] Specifically, the discharge component is a U-shaped screw conveyor 4, with an opening at the top for the particles to fall into; one end of the U-shaped screw conveyor 4 extends parallel to the axial direction of the filter cylinder 2 to the water tank 1, and the spiral auger 41 built into the U-shaped screw conveyor 4 is used to hang and transport the particles.

[0026] It is worth mentioning that the U-shaped screw conveyor 4 that is already available on the market can be used; by driving the central shaft 42 of the U-shaped screw conveyor 4 to rotate, the screw auger 41 on the central shaft 42 can be driven to rotate, and the particles and sand in the U-shaped screw conveyor 4 can be scraped and transported along the axial direction of the filter cylinder 2.

[0027] Preferably, the U-shaped screw conveyor 4 and the rotating shaft 23 are connected by belt drive; specifically, the output shaft of the drive motor 25 is connected to the rotating shaft 23 by a coupling, and the rotating shaft 23 and the central shaft 42 are connected by belt drive; when the output shaft of the drive motor 25 rotates, it can drive the U-shaped screw conveyor 4 and the scraper 24 to work.

[0028] It is worth mentioning that the filtered wastewater is temporarily stored in pool 1, and can be sent to the next process by the transfer pump 5.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if these modifications and modifications of the present invention fall within the scope of the machine equivalents of the claims of the present invention, the present invention also intends to include these modifications and modifications.
