[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse in drinking water. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people.

[0003] Traditional septic tank sewage treatment devices typically use multiple sedimentation tanks to settle sewage at each level before directly discharging it into the sedimentation tanks for treatment. However, during the traditional sewage discharge process, the sewage contains a large amount of debris, which is often discharged directly into the sedimentation tanks without filtration. This debris accumulates continuously in the sedimentation tanks, causing the space within the tanks to shrink and thus affecting the sedimentation effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a concrete septic tank sewage treatment device, which has the advantages of filtering sewage and automatically collecting and discharging debris, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a concrete septic tank sewage treatment device, including a sedimentation tank, a collection chamber installed at the top of the sedimentation tank, a discharge pipe fixedly mounted on the outer wall of the collection chamber, a discharge trough fixedly mounted at the bottom of the collection chamber, a rotating plate rotatably connected in the inner cavity of the collection chamber, a driven gear fixedly mounted at the bottom of the rotating plate, a drive motor fixedly mounted at the top of the sedimentation tank, a drive gear fixedly mounted on the power output shaft of the drive motor, an inlet pipe fixedly mounted at the bottom of the collection chamber, a filter chamber installed in the inner cavity of the collection chamber, and the bottom of the filter chamber... The filter chamber is fixedly equipped with a closed plate. A drop chamber is located at the bottom of the collection chamber, and a drop opening is located at the bottom of the filter chamber. A limit rod is fixedly installed on the inner wall of the filter chamber. A movable plate is movably sleeved on the outer wall of the limit rod. A drive spring is movably sleeved on the outer wall of the limit rod. A connecting hole is provided on the outer wall of the filter chamber. A filter plate is rotatably connected to the inner cavity of the filter chamber. A rotary motor is fixedly installed on the outer wall of the filter chamber. A drive screw is fixedly installed on the power output shaft of the rotary motor. A lifting block is threadedly connected to the outer wall of the drive screw. A connecting plate is rotatably connected to the outer wall of the lifting block.

[0006] As a preferred technical solution of this utility model: the outer wall of the driving gear meshes with the outer wall of the driven gear, and the outer wall of the rotating plate is connected to the outer wall of the filter chamber.

[0007] As a preferred technical solution of this utility model: the two ends of the outer wall of the drive spring are in contact with the outer wall of the moving plate and the outer wall of the limiting rod, respectively, and the drive spring is made of high carbon steel.

[0008] As a preferred technical solution of this utility model: the outer wall of the connecting plate at the end away from the lifting block is fixedly connected to the outer wall of the filter plate, and the outer wall shape of the moving plate is larger than the inner wall shape of the connecting hole.

[0009] As a preferred technical solution of this utility model: the number of filter chambers is four, and the four filter chambers are respectively installed on the outer wall of the rotating plate.

[0010] As a preferred technical solution of this utility model: the inner cavity of the inlet pipe is connected to the inner cavity of the sedimentation tank, and the outer wall diameter of the sealing plate is equal to the inner wall diameter of the collection chamber.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This concrete septic tank sewage treatment device, through the filter chamber set in the inner cavity of the collection chamber, can perform preliminary filtration of sewage under the action of the filter plate in the filter chamber, so that the impurities are retained on the top of the filter plate, and the sewage can pass through the filter plate into the sedimentation tank, where it settles. This avoids the direct discharge of unfiltered sewage into the sedimentation tank in traditional equipment, which would cause excessive accumulation in the sedimentation tank and thus affect the capacity of the sedimentation tank.

[0013] 2. This concrete septic tank sewage treatment device uses a filter plate installed in the inner cavity of the filter chamber and a connecting plate installed on the outer wall of the filter plate. When the position of the filter chamber is moved to the top of the discharge port, the drive screw is rotated by a rotary motor, which causes the filter plate to rotate. Under the action of the filter plate rotation, the impurities are released and discharged outward along the discharge trough. The position of the filter chamber is continuously rotated to continuously filter and discharge the impurities, thereby better preventing impurities from entering the sedimentation tank, so as to facilitate better subsequent sewage treatment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 6 A concrete septic tank sewage treatment device includes a sedimentation tank 1, a collection chamber 2 installed on the top of the sedimentation tank 1, a discharge pipe 3 fixedly mounted on the outer wall of the collection chamber 2, a discharge trough 4 fixedly mounted on the bottom of the collection chamber 2, a rotating plate 5 rotatably connected to the inner cavity of the collection chamber 2, a driven gear 6 fixedly mounted on the bottom of the rotating plate 5, a drive motor 8 fixedly mounted on the top of the sedimentation tank 1, a drive gear 7 fixedly mounted on the power output shaft of the drive motor 8, an inlet pipe 9 fixedly mounted on the bottom of the collection chamber 2, a filter chamber 10 installed in the inner cavity of the collection chamber 2, a sealing plate 11 fixedly mounted on the bottom of the filter chamber 10, and a bottom of the collection chamber 2... The filter chamber 10 has a drop chamber 12 and a drop opening 13 at the bottom. A limit rod 14 is fixedly mounted on the inner wall of the filter chamber 10. A movable plate 16 is movably sleeved on the outer wall of the limit rod 14. A drive spring 15 is movably sleeved on the outer wall of the limit rod 14. A connecting hole 17 is opened on the outer wall of the filter chamber 10. A filter plate 18 is rotatably connected to the inner cavity of the filter chamber 10. A rotary motor 20 is fixedly mounted on the outer wall of the filter chamber 10. A drive screw 19 is fixedly mounted on the power output shaft of the rotary motor 20. A lifting block 22 is threadedly connected to the outer wall of the drive screw 19. A connecting plate 21 is rotatably connected to the outer wall of the lifting block 22.

[0023] In the above structure, by setting a rotating plate 5 in the inner cavity of the collection chamber 2 and setting a driven gear 6 at the bottom of the rotating plate 5, the drive gear 7 is driven to rotate under the action of the drive motor 8, and the driven gear 6 is driven during the rotation of the drive gear 7, so that the driven gear 6 rotates in the inner cavity of the collection chamber 2, thereby driving the filter chamber 10 to rotate, and the filter chamber 10 can be replaced.

[0024] In a preferred embodiment: the outer wall of the drive gear 7 meshes with the outer wall of the driven gear 6, and the outer wall of the rotating plate 5 is connected to the outer wall of the filter chamber 10.

[0025] In the above structure, by setting a driven gear 6 at the bottom of the rotating plate 5, setting a drive motor 8 at the top of the collection chamber 2, and setting a drive gear 7 on the power output shaft of the drive motor 8, the driven gear 6 and the rotating plate 5 are driven, and the filter chamber 10 is driven to rotate during the rotation of the rotating plate 5.

[0026] In a preferred embodiment, the two ends of the outer wall of the drive spring 15 are in contact with the outer wall of the moving plate 16 and the outer wall of the limiting rod 14, respectively, and the drive spring 15 is made of high carbon steel.

[0027] In the above structure, by using the movable plate 16 and drive spring 15 provided on the outer wall of the limiting rod 14, when sewage is introduced into the inner cavity of the filter chamber 10 through the discharge pipe 3, the movable plate 16 will move along the outer wall of the limiting rod 14 under the pressure of the sewage, thereby releasing the outer wall of the movable plate 16 from the sealing of the connection hole 17, allowing the sewage to enter the inner cavity of the filter chamber 10, and under the filtration of the filter plate 18, the filtered sewage will be released into the inner cavity of the inlet pipe 9 through the drop port 13.

[0028] In a preferred embodiment: the outer wall of the connecting plate 21 away from the lifting block 22 is fixedly connected to the outer wall of the filter plate 18, and the outer wall shape of the moving plate 16 is larger than the inner wall shape of the connecting hole 17.

[0029] In the above structure, the connecting plate 21 provided on the outer wall of the filter plate 18 causes the lifting block 22 to move up and down along the outer wall of the drive screw 19 under the action of the rotary motor 20. During the up and down movement of the lifting block 22, it pushes the outer wall of the connecting plate 21, thereby causing the connecting plate 21 to drive the filter plate 18 to rotate. This causes the filter plates 18 on both sides to expand outward at the same time, releasing larger impurities filtered on the outer wall of the filter plate 18 through the drop port 13 and the drop chamber 12 into the inner cavity of the discharge trough 4, and then releasing them outward along the inner cavity of the discharge trough 4.

[0030] In a preferred embodiment, there are four filter chambers 10, and the four filter chambers 10 are respectively installed on the outer wall of the rotating plate 5.

[0031] In the above structure, four filter chambers 10 are installed on the outer wall of the rotating plate 5. The rotating plate 5 is rotated by the drive motor 8 and the drive gear 7, thereby rotating the filter chambers 10 in turn. This allows the equipment to continuously filter sewage and discharge the filtered impurities to the outside through the discharge tank 4.

[0032] In a preferred embodiment: the inner cavity of the inlet pipe 9 is connected to the inner cavity of the sedimentation tank 1, and the outer diameter of the sealing plate 11 is equal to the inner diameter of the collection chamber 2.

[0033] In the above structure, by setting a sealing plate 11 on the outer wall of the filter chamber 10, during the rotation of the filter chamber 10, the connecting hole 17 on the outer wall of the filter chamber 10 will be misaligned with the inner cavity of the discharge pipe 3. At this time, the outer wall of the sealing plate 11 will block the inner cavity of the discharge pipe 3, thereby blocking the sewage in the discharge pipe 3. Only when the next filter chamber 10 moves to the position of the discharge pipe 3 can the sewage in the inner cavity of the discharge pipe 3 be released into the inner cavity of the filter chamber 10.

[0034] Working Principle: During the operation of the above equipment, when treating sewage, the sewage needs to be fed into the inner cavity of the settling tank 1 for settling. The sewage settles within the settling tank 1, and is then released into the inner cavity of the filter chamber 10 through the discharge pipe 3. Under the pressure of the sewage, the moving plate 16 is pushed, causing its outer wall to separate from the inner wall of the filter chamber 10 and compressing the drive spring 15. This allows the sewage to enter the inner cavity of the filter chamber 10 and be filtered by the filter plate 18. Larger impurities are blocked by the filter plate 18, while the sewage passes through the filter plate 18 and continues to fall downwards, passing through the inlet pipe 9 into the inner cavity of the settling tank 1. After five minutes of use in the filter chamber 10, the drive motor 8 is started, causing the rotating plate 5 to rotate, thus rotating the filter chamber 10. The outer wall of the connecting hole 17 and the discharge... After the inner cavity of the discharge pipe 3 is misaligned, the sealing plate 11 will block the inner cavity of the discharge pipe 3 to prevent sewage from flowing out. Then, the next filter chamber 10 will move to the top of the inlet pipe 9 and rotate in a cycle. When the filter chamber 10 moves to the top of the drop chamber 12 after one filtration, the rotary motor 20 will be started. The rotary motor 20 will drive the drive screw 19 to rotate. During the rotation of the drive screw 19, the lifting block 22 will be driven, causing the lifting block 22 to move downward along the outer wall of the drive screw 19. During the movement of the lifting block 22, the filter plate 18 will be flipped, causing the two filter plates 18 to separate. Then, the debris on the top of the filter plate 18 can pass through the drop port 13 and the drop chamber 12 into the inner cavity of the discharge tank 4 and be discharged outward under the action of the discharge tank 4, thus completing the filtration of sewage and the collection of debris.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
