Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly relates to a domestic sewage resource utilization treatment device. Background Art

[0002] Domestic sewage is the wastewater discharged in residents' daily life, mainly from residential buildings and public buildings, such as residences, institutions, schools, hospitals, stores, public places, and the toilets of industrial enterprises.

[0003] Domestic sewage can be reused after purification treatment. Filtering domestic sewage is the first step, which can remove larger domestic garbage in the domestic sewage. When the existing treatment device filters, the garbage on the mesh plate needs to be regularly cleaned, otherwise the mesh plate will be blocked. Therefore, corresponding improvements are made to solve this problem. Summary of the Invention

[0004] Based on the technical problems existing in the prior art, the present invention proposes a domestic sewage resource utilization treatment device.

[0005] A domestic sewage resource utilization treatment device proposed by the present invention includes a box body. A water inlet pipe is provided at the top of the box body, and a water outlet pipe is provided on one side of the box body. A mesh plate is fixed inside the box body. Discharge ports are opened on both sides of the box body. Inclined portions are provided on both sides of the mesh plate, and the inclined portions extend downward to the discharge ports. A pair of push plates symmetrically distributed on both sides are arranged at the middle position of the top of the mesh plate. The push plates and the mesh plate are elastically connected by springs. A driving assembly is further provided inside the box body. Domestic sewage is introduced into the water inlet pipe through a pipeline, and then the sewage flows into the box body. When the sewage passes through the mesh plate, it is filtered, and the domestic garbage is blocked on the mesh plate. By driving the driving assembly to intermittently separate the two push plates, the two push plates will continuously push the garbage on the mesh plate to both sides, and then the garbage will flow out from the discharge ports along the inclined portions, thus effectively avoiding the situation that the mesh plate is blocked.

[0006] Preferably, the driving assembly includes a gate valve assembly disposed in the water inlet pipe. The gate valve assembly is used to periodically close the water inlet pipe. An inverted V-shaped angle is formed between the two push plates, and the vertical heights of the two push plates are not equal. An extension portion is provided at the middle position of the push plate, and a rack is fixed to the back surface of the extension portion. A horizontal cross bar is fixed in the water inlet pipe, and a shaft column is rotatably connected to the cross bar. A gear is fixedly sleeved at the bottom end of the shaft column. The two racks are respectively engaged in front of and behind the gear. A cleaning structure is provided on the shaft column. The sewage flowing down from the water inlet pipe is located in the area where the two extension portions are located, and the sewage will impact on the extension portions. In this way, the two push plates will be separated after being stressed. Then the gate valve assembly will close the water inlet pipe, and the push plates will reset under the action of elastic force, so that the two push plates are intermittently separated. When the push plates move, they will synchronously drive the racks to move through the extension portions. Then the racks will engage the gear to drive the shaft column to rotate, and the shaft column will synchronously drive the cleaning structure to rotate. The cleaning structure will clean the garbage in the sewage flowing downward outward, thus effectively reducing the accumulation of garbage between the two push plates. And because the vertical heights of the two push plates are not equal, when the two push plates move closer to the middle, the garbage between them will be pushed to the side with a lower height, thus effectively reducing the accumulation of garbage between the two push plates.

[0007] Preferably, the gate valve assembly includes a semi-circular plate two fixed to the top end of the shaft column, and a semi-circular plate one fixed in the water inlet pipe and located on the top surface of the semi-circular plate two. When the shaft column rotates, it synchronously drives the semi-circular plate two to rotate. In this way, the semi-circular plate two will cooperate with the semi-circular plate one to periodically close the water inlet pipe.

[0008] Preferably, the gate valve assembly includes a sealing plate located in the water inlet pipe and capable of blocking the pipe orifice of the water inlet pipe. A water leakage hole is provided on the sealing plate. A connecting rod is fixed to the bottom of the sealing plate, and the bottom of the connecting rod is fixed to one of the extension portions. When the extension portion moves, it will synchronously drive the sealing plate to move through the connecting rod. When the water leakage hole is aligned with the pipe orifice of the water inlet pipe, the water inlet pipe is opened, thus realizing the periodic closing of the water inlet pipe.

[0009] Preferably, the cleaning structure includes a mesh cover located below the water inlet pipe. The mesh cover is fixedly sleeved on the shaft column. The mesh cover is in a frustum structure. When the sewage flows downward, it can normally pass through the mesh cover and then impact on the extension portions, while the garbage in the sewage cannot pass through the mesh cover and will be thrown outward along the conical surface of the mesh cover by the rotating mesh cover. In this way, the garbage can enter the position outside the two push plates, thus avoiding the accumulation of garbage between the two push plates.

[0010] Preferably, the cleaning structure includes a sleeve located below the water inlet pipe. The sleeve is fixedly sleeved on the shaft column, and a dense number of cleaning rods are fixed on the outer circumferential wall of the sleeve. When the sewage passes through the position of the cleaning rods, the rotating cleaning rods will throw the garbage outwards, so that the garbage can enter the position outside the two push plates, thus avoiding the accumulation of garbage between the two push plates.

[0011] Preferably, a plurality of the cleaning rods together form a frustum structure, so that part of the garbage can slide down along the side surface of the frustum formed when the cleaning rods rotate, further reducing the garbage from entering between the two push plates.

[0012] Preferably, the driving assembly includes a tee pipe connected below the water inlet pipe. The tee pipe is composed of a vertical main pipe and two horizontal branch pipes. The bottom end of the main pipe is rotatably connected to a shaft rod. A paddle is fixed at the top end of the shaft rod, and an oval push block located between the two push plates is fixed at the bottom end of the shaft rod. The sewage enters the branch pipes from the main pipe and flows onto the net plate, so that the garbage can fall into the area outside the two push plates. When the sewage flows, it will drive the paddle to rotate around the shaft rod, and then the shaft rod will synchronously drive the push block to rotate, and the push block will intermittently separate the two push plates.

[0013] Preferably, a pair of guide columns are fixed on the back surfaces of the two push plates. The spring is sleeved on the guide columns, and a guide sleeve is also sleeved on the guide columns. The guide sleeve is fixed on the top of the net plate. The two ends of the spring are respectively fixedly connected to the push plate and the guide sleeve, so that an elastic connection can be formed between the push plate and the net plate through the spring, and the lateral limit movement of the push plate can be carried out through the cooperation between the guide sleeve and the guide columns.

[0014] Compared with the prior art, the present invention provides a domestic sewage resource utilization treatment device, which has the following beneficial effects:

[0015] 1. A domestic sewage resource utilization treatment device, by arranging the push plates, when the sewage passes through the net plate, it is filtered, and the domestic garbage is blocked on the net plate. By driving the assembly to intermittently separate the two push plates, the two push plates will continuously push the garbage on the net plate to both sides, and then the garbage will flow out from the discharge port along the inclined part, thus effectively avoiding the situation of the net plate being blocked.

[0016] 2. A domestic sewage resource utilization and treatment device. By setting push plates that form a V-shaped angle, the sewage flowing down from the water inlet pipe is located in the area where the two extension parts are located, and the sewage will impact the extension parts. In this way, the two push plates will separate when they are stressed. Then, the gate valve assembly will close the water inlet pipe, and the push plates will reset under the action of elastic force, so that the two push plates will separate intermittently. When the push plates move, they will synchronously drive the rack to move through the extension parts. Then, the rack will engage with the gear to drive the shaft column to rotate, and the shaft column will synchronously drive the cleaning structure to rotate. The cleaning structure will clean the garbage in the sewage flowing downward outward, thus effectively reducing the accumulation of garbage between the two push plates. And because the vertical heights of the two push plates are not equal, when the two push plates move closer to the middle, the garbage between them will be pushed to the side with a lower height, thus effectively reducing the accumulation of garbage between the two push plates.

[0017] 3. A domestic sewage resource utilization and treatment device. By setting semi-circular plate one and semi-circular plate two, when the shaft column rotates, it will synchronously drive semi-circular plate two to rotate. In this way, semi-circular plate two will cooperate with semi-circular plate one to periodically close the water inlet pipe.

[0018] 4. A domestic sewage resource utilization and treatment device. By setting a sealing plate, when the extension part moves, it will synchronously drive the sealing plate to move through the connecting rod. When the water leakage hole is aligned with the pipe orifice of the water inlet pipe, the water inlet pipe will be opened, thus realizing the periodic closing of the water inlet pipe.

[0019] 5. A domestic sewage resource utilization and treatment device. By setting a mesh cover, the sewage can flow downward through the mesh cover normally and then impact the extension part, while the garbage in the sewage cannot pass through the mesh cover and will be thrown outward along the conical surface of the mesh cover by the rotating mesh cover. In this way, the garbage can enter the position outside the two push plates, thus avoiding the accumulation of garbage between the two push plates.

[0020] 6. A domestic sewage resource utilization and treatment device. By setting a cleaning rod, when the sewage passes through the cleaning rod, the rotating cleaning rod will throw the garbage outward. In this way, the garbage can enter the position outside the two push plates, thus avoiding the accumulation of garbage between the two push plates.

[0021] 7. A domestic sewage resource utilization and treatment device. By setting a push block, the sewage enters the branch pipe from the main pipe and flows onto the mesh plate. In this way, the garbage can fall into the area outside the two push plates. When the sewage flows, it will drive the paddle to rotate around the shaft rod, and then the shaft rod will synchronously drive the push block to rotate. The push block will intermittently separate the two push plates. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0032] 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 of the embodiments.

[0033] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0034] Referring to Figures 1 - 9 , a domestic sewage resource utilization treatment device, including a box body 1, a water inlet pipe 2 is arranged at the top of the box body 1, a water outlet pipe 3 is arranged on one side of the box body 1, a mesh plate 4 is fixed inside the box body 1, discharge ports 6 are opened on both sides of the box body 1, inclined parts 5 are arranged on both sides of the mesh plate 4, and the inclined parts 5 extend downward to the discharge ports 6. A pair of push plates 7 symmetrically distributed on both sides are arranged at the middle position of the top of the mesh plate 4. An elastic connection is formed between the push plates 7 and the mesh plate 4 through springs 28. A driving component is also arranged inside the box body 1. Domestic sewage is introduced into the water inlet pipe 2 through a pipeline, and then the sewage flows into the box body 1. When the sewage passes through the mesh plate 4, it is filtered, and the domestic garbage is blocked on the mesh plate 4. By driving the two push plates 7 to be intermittently separated by the driving component, the two push plates 7 will continuously push the garbage on the mesh plate 4 to both sides, and then the garbage will flow out from the discharge port 6 along the inclined parts 5, thus effectively avoiding the situation that the mesh plate 4 is blocked.

[0035] In Embodiment 1, the driving component includes a gate valve component arranged in the water inlet pipe 2. The gate valve component is used to periodically close the water inlet pipe 2. An octagonal opening angle is formed between the two push plates 7, and the vertical heights of the two push plates 7 are not equal. An extension part 8 is arranged at the middle position of the push plate 7, and a rack 12 is fixed on the back of the extension part 8. A horizontal cross bar 9 is fixed in the water inlet pipe 2, and a shaft column 10 is rotatably connected to the cross bar 9. A gear 11 is fixedly sleeved at the bottom end of the shaft column 10. The two racks 12 are respectively engaged in front of and behind the gear 11. A cleaning structure is arranged on the shaft column 10. The sewage flowing down from the water inlet pipe 2 is located in the area where the two extension parts 8 are located, and the sewage will impact on the extension parts 8. In this way, the two push plates 7 will be separated after being stressed. Then the gate valve component will close the water inlet pipe 2, and the push plates 7 will reset under the action of elastic force, so that the two push plates 7 are intermittently separated. When the push plates 7 move, the racks 12 will be synchronously driven to move through the extension parts 8. Then the racks 12 will engage the gear 11 to drive the shaft column 10 to rotate, and the shaft column 10 will synchronously drive the cleaning structure to rotate. The cleaning structure will clean the garbage in the sewage flowing downward outward, thus effectively reducing the accumulation of garbage between the two push plates 7. And because the vertical heights of the two push plates 7 are not equal, when the two push plates 7 move closer to the middle, the garbage between them will be pushed to the side with a lower height, thus effectively reducing the accumulation of garbage between the two push plates 7.

[0036] Among them, the gate valve assembly includes a semi-circular plate two 14 fixed to the top end of the shaft column 10. A semi-circular plate one 13 is fixed inside the water inlet pipe 2 and located on the top surface of the semi-circular plate two 14. When the shaft column 10 rotates, it synchronously drives the semi-circular plate two 14 to rotate. In this way, the semi-circular plate two 14 will cooperate with the semi-circular plate one 13 to periodically close the water inlet pipe 2.

[0037] In Embodiment 2, the gate valve assembly includes a sealing plate 16 located inside the water inlet pipe 2 and capable of blocking the pipe orifice of the water inlet pipe 2. A water leakage hole 17 is opened on the sealing plate 16. A connecting rod 15 is fixed to the bottom of the sealing plate 16. The bottom of the connecting rod 15 is fixed to one of the extension parts 8. When the extension part 8 moves, it will synchronously drive the sealing plate 16 to move through the connecting rod 15. When the water leakage hole 17 is aligned with the pipe orifice of the water inlet pipe 2, the water inlet pipe 2 is opened, thereby realizing the periodic closing of the water inlet pipe 2.

[0038] Among them, the cleaning structure includes a mesh cover 18 located below the water inlet pipe 2. The mesh cover 18 is fixedly sleeved on the shaft column 10. The mesh cover 18 is in a frustum structure. When the sewage flows downward, it can normally pass through the mesh cover 18 and then impact on the extension part 8, while the garbage in the sewage cannot pass through the mesh cover 18 and will be thrown outward along the conical surface of the mesh cover 18 by the rotating mesh cover 18. In this way, the garbage can enter the position outside the two push plates 7, thereby avoiding the accumulation of garbage between the two push plates 7.

[0039] In Embodiment 3, the cleaning structure includes a sleeve 19 located below the water inlet pipe 2. The sleeve 19 is fixedly sleeved on the shaft column 10. A dense number of cleaning rods 20 are fixed to the outer circumferential wall of the sleeve 19. When the sewage passes through the position of the cleaning rods 20, the rotating cleaning rods 20 will throw the garbage outward. In this way, the garbage can enter the position outside the two push plates 7, thereby avoiding the accumulation of garbage between the two push plates 7.

[0040] Furthermore, a plurality of cleaning rods 20 together form a frustum structure, so that part of the garbage can slide down along the frustum side surface formed when the cleaning rods 20 rotate, further reducing the garbage entering between the two push plates 7.

[0041] In Embodiment 4, the driving assembly includes a tee pipe connected below the water inlet pipe 2. The tee pipe is composed of a vertical main pipe 21 and two horizontal branch pipes 22. The bottom end of the main pipe 21 is rotatably connected to a shaft rod 23. A paddle 24 is fixed to the top end of the shaft rod 23. An elliptical push block 25 located between the two push plates 7 is fixed to the bottom end of the shaft rod 23. The sewage enters the branch pipe 22 from the main pipe 21 and flows onto the mesh plate 4. In this way, the garbage can fall into the area outside the two push plates 7. When the sewage flows, it will drive the paddle 24 to rotate around the shaft rod 23, and then the shaft rod 23 will synchronously drive the push block 25 to rotate. The push block 25 will intermittently separate the two push plates 7.

[0042] Wherein, a pair of guide columns 27 are fixed to the back surfaces of both push plates 7, a spring 28 is sleeved on the guide columns 27, a guide sleeve 26 is also sleeved on the guide columns 27, the guide sleeve 26 is fixed to the top of the mesh plate 4, and two ends of the spring 28 are fixedly connected to the push plate 7 and the guide sleeve 26 respectively. In this way, an elastic connection can be formed between the push plate 7 and the mesh plate 4 through the spring 28, and the push plate 7 can be limited to move horizontally through the cooperation between the guide sleeve 26 and the guide columns 27.

[0043] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
