Description

Technical Field

[0001] This utility model relates to the technical field of purification and treatment devices, specifically a domestic sewage purification and treatment device. Background Technology

[0002] A domestic sewage purification and treatment device is a complete set of equipment that integrates physical, chemical, and biological treatment processes to remove pollutants such as organic matter, suspended solids, nitrogen, and phosphorus from domestic sewage.

[0003] Existing domestic sewage treatment devices generally suffer from problems such as low solid-liquid separation efficiency, easy clogging of filter screens, and unstable treatment process in practical applications. Since the filter screen is usually stationary during use, impurities easily accumulate on the filter screen, which obstructs the water flow channel, preventing the liquid from passing through smoothly and reducing the filtration effect. This not only increases the risk of filter screen clogging but also causes uneven separation of liquid and solid, resulting in poor solid-liquid separation effect. Consequently, it affects the working efficiency of subsequent sewage treatment devices, making it impossible to effectively guarantee the efficiency and stability of sewage treatment.

[0004] In view of this, we propose a domestic sewage purification and treatment device. Utility Model Content

[0005] The purpose of this utility model is to provide a domestic sewage purification and treatment device, which solves the problems of poor solid-liquid separation effect, unstable treatment and difficulty in guaranteeing the overall purification efficiency of existing domestic sewage purification and treatment devices due to the easy clogging of the filter screen when it is stationary.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a domestic sewage purification and treatment device, comprising an inclined pipe and a vertical pipe, which are interconnected and intersected. The inner walls of the inclined pipe and the vertical pipe are connected. A solid waste discharge pipe is fixedly connected to the bottom of the inclined pipe, and a sewage processor is fixedly connected to the bottom of the vertical pipe. A solid-liquid separation mechanism is provided on the inclined pipe and the vertical pipe. The solid-liquid separation mechanism includes: a drive motor, which is fixedly connected to the outer wall of the inclined pipe. A drive gear is fixedly connected to the output end of the drive motor. An external magnetic coupling is rotatably connected to the outer wall of the inclined pipe. The outer wall of the external magnetic coupling is provided with an external gear ring, which meshes with a drive gear. An internal magnetic coupling is rotatably connected to the inner wall of the inclined pipe. A hollow cylinder is fixedly connected to the inner wall of the internal magnetic coupling, and the hollow cylinder is rotatably connected to the inner wall of the inclined pipe. A filter screen is provided at the top of the hollow cylinder. The filter screen is a cylindrical shape with open ends and is located at the intersection of the inclined pipe and the vertical pipe. A front section cylinder is fixedly connected to the top of the filter screen, and a spiral blade is fixedly connected to the inner wall of the front section cylinder. A cleaning mechanism is provided on the vertical pipe for cleaning the adhering substances on the inner wall of the filter screen.

[0007] Preferably, the cleaning mechanism includes a rigid pipe fixedly connected to a vertical pipe. One end of the rigid pipe is connected to a collection bucket, which is located at the bottom of the vertical pipe and is used to collect part of the wastewater filtered by the filter screen. The other end of the rigid pipe is connected to a water pump, and the output end of the water pump is rotatably connected to a hollow disc block. The bottom circumference of the hollow disc block is arranged with a plurality of angled nozzles, which are located at the top of the filter screen.

[0008] Preferably, the water pump is provided with a support frame, which is fixedly connected to the inner wall of the vertical pipe.

[0009] Preferably, the surface of the spiral blade has a turbulence pattern to enhance the deceleration effect of the sewage fluid.

[0010] Preferably, a shock-absorbing pad is provided between the drive motor and the inclined through pipe to reduce the vibration generated by the motor operation.

[0011] Preferably, the top edge of the filter screen is provided with a sealing ring to prevent sewage from bypassing the filter screen and entering the vertical pipe.

[0013] By employing the above technical solution, this utility model provides a domestic sewage purification and treatment device. It possesses at least the following beneficial effects: 1. This utility model incorporates a solid-liquid separation mechanism. A drive motor drives gears, a magnetic coupling, and a hollow cylinder to form a transmission linkage with the filter screen. This allows the filter screen to prevent impurities from accumulating on its surface and achieve solid-liquid separation of wastewater during rotation. Simultaneously, the spiral blades in the front section of the cylinder guide and decelerate the wastewater, ensuring it enters the filter screen evenly. This guarantees that the liquid flows smoothly into the vertical pipe and towards the wastewater processor, while solid impurities are effectively intercepted and discharged, thereby improving the efficiency and stability of wastewater purification.

[0014] 2. This utility model incorporates a cleaning mechanism that collects a portion of the wastewater separated by the filter screen using a collection bucket. This wastewater is then transported through a rigid pipe to a water pump, pressurized, and enters a hollow disc block. The outer surface of the filter screen is then subjected to high-pressure rinsing by angled nozzles arranged in an array at the bottom of the disc block. This process promptly removes adhering impurities, maintains the filter screen's unobstructed flow and efficient separation function, avoids clogging that could reduce treatment efficiency, and ensures the long-term stable operation and excellent purification effect of the device.

[0017] 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.

[0018] Please see Figure 1 - Figure 6As shown, this utility model provides a technical solution: a domestic sewage purification and treatment device, including an inclined pipe 1 and a vertical pipe 2, which are intersected and connected to each other. The inner walls of the inclined pipe 1 and the vertical pipe 2 are connected. A solid waste discharge pipe 3 is fixedly connected to the bottom of the inclined pipe 1, and a sewage processor 4 is fixedly connected to the bottom of the vertical pipe 2. A solid-liquid separation mechanism 5 is provided on the inclined pipe 1 and the vertical pipe 2. The solid-liquid separation mechanism 5 includes: a drive motor 51, which is fixedly connected to the outer wall of the inclined pipe 1. A drive gear 52 is fixedly connected to the output end of the drive motor 51. The outer wall of the inclined pipe 1 rotates... An external magnetic coupling 53 is dynamically connected, and an external gear ring is provided on the outer wall of the external magnetic coupling 53. The external gear ring of the external magnetic coupling 53 meshes with the drive gear 52. An internal magnetic coupling 54 is rotatably connected to the inner wall of the inclined pipe 1. A hollow cylinder 55 is fixedly connected to the inner wall of the internal magnetic coupling 54. The hollow cylinder 55 is rotatably connected to the inner wall of the inclined pipe 1. A filter screen 56 is provided on the top of the hollow cylinder 55. The filter screen 56 is a cylindrical shape with open ends. The filter screen 56 is located at the intersection and connection of the inclined pipe 1 and the vertical pipe 2. A front section cylinder 58 is fixedly connected to the top of the filter screen 56. A spiral blade 5 is fixedly connected to the inner wall of the front section cylinder 58. 9. After the drive motor 51 is turned on, its output end drives the drive gear 52 to rotate. The drive gear 52 meshes with the outer gear ring of the outer magnetic coupling 53, causing the outer magnetic coupling 53 to rotate accordingly. The outer magnetic coupling 53 drives the inner magnetic coupling 54 to rotate synchronously through magnetic force. The inner magnetic coupling 54 is fixedly connected to the hollow cylinder 55, thereby driving the hollow cylinder 55 and the filter screen 56 fixed on its top to rotate together. During the rotation, the filter screen 56 can prevent impurities from accumulating and clogging on its surface and achieve solid-liquid separation. Sewage enters the front section cylinder 58 through the inclined pipe 1. The spiral blades 59 on the inner wall of the front section cylinder 58 guide and decelerate the inflowing sewage. The function of the filter screen 56 is to reduce the flow rate of sewage and allow it to enter the filter screen 56 more evenly. The liquid part then flows smoothly into the vertical pipe 2 and into the sewage processor 4 for further purification, while the solid impurities are intercepted by the filter screen 56 and guided into the hollow cylinder 55, and then discharged through the solid waste discharge pipe 3. The entire transmission sequence realizes the linkage of the drive motor 51 to the drive gear 52, the external magnetic coupling 53, the internal magnetic coupling 54, the hollow cylinder 55 and the filter screen 56, and finally achieves the purpose of slowing down, filtering, separating solid and liquid and discharging impurities from sewage. A cleaning mechanism 6 is provided on the vertical pipe 2 to clean the adhering substances on the inner wall of the filter screen 56.

[0019] The cleaning mechanism 6 includes a rigid pipe 61, which is fixedly connected to the vertical pipe 2. One end of the rigid pipe 61 is connected to a collection tank 62, which is located at the bottom of the vertical pipe 2 and is used to collect part of the wastewater filtered by the filter screen 56. The other end of the rigid pipe 61 is connected to a water pump 63. The output end of the water pump 63 is rotatably connected to a hollow disc block 64. Several angled nozzles 65 are arranged in a circular array on the bottom of the hollow disc block 64. The angled nozzles 65 are located on the top of the filter screen 56. The collection tank 62 at the bottom of the vertical pipe 2 is connected to the water pump 63 through the rigid pipe 61. Part of the wastewater separated by the filter screen 56 enters the collection tank 62 and is collected. Wastewater in the collection tank 62 is transported to the water pump 63 along the rigid pipe 61. After the water pump 63 starts, it pressurizes the wastewater and delivers it to the hollow disc block 64 through its output end. The hollow disc block 64 forms an annular flow channel inside. The wastewater output by the water pump 63 is distributed through this flow channel to a number of angled nozzles 65 evenly arrayed at the bottom of the hollow disc block 64. The angled nozzles 65 spray the wastewater in the form of high-pressure water jets onto the top of the filter screen 56, rinsing and cleaning the outer surface of the filter screen 56, thereby effectively removing solid impurities adhering to the filter screen 56, ensuring that the filter screen 56 remains unobstructed and has an efficient separation function. The sprayed wastewater will then flow down the filter screen 56 into the vertical pipe 2.

[0020] The water pump 63 is equipped with a support frame, which is fixedly connected to the inner wall of the vertical pipe 2. The surface of the spiral blade 59 has a turbulence pattern to enhance the deceleration effect of the sewage fluid. A shock-absorbing pad is provided between the drive motor 51 and the inclined pipe 1 to reduce the vibration generated by the motor operation. A sealing ring is provided on the top edge of the filter screen 56 to prevent sewage from entering the vertical pipe 2 around the filter screen 56. An inspection port is provided at the top of the vertical pipe 2 for easy maintenance.

[0021] In use, the wastewater purification device of this utility model first starts the drive motor 51. The output end of the drive motor 51 drives the drive gear 52 to rotate. The drive gear 52 meshes with the outer gear ring of the outer magnetic coupling 53, thereby causing the outer magnetic coupling 53 to rotate accordingly. When the outer magnetic coupling 53 rotates, it drives the inner magnetic coupling 54 to rotate synchronously through magnetic force. The inner magnetic coupling 54 is fixedly connected to a hollow cylinder 55. Therefore, the hollow cylinder 55 and the filter screen 56 fixed on its top rotate under the action of magnetic coupling. The rotating filter screen 56 can prevent impurities from accumulating and clogging on its surface and achieve solid-liquid separation. Wastewater flows into the front section cylinder 58 through the inclined pipe 1. The inner wall of the front section cylinder 58 is fixedly connected to a spiral blade 59. The spiral blade 59 guides and decelerates the inflowing wastewater, reducing the flow rate of the wastewater and allowing it to enter the filter screen 56 more evenly. At this time, the liquid part can smoothly pass through the filter screen 56 into the vertical pipe 2 and flow to the wastewater processor 4 for further purification. Solid impurities are intercepted by the filter screen 56 and guided into the hollow cylinder 55, and then discharged through the solid waste pipe 3. The cleaning mechanism 6 set on the vertical pipe 2 is used to wash the outer surface of the filter screen 56. Specifically, the collection bucket 62 at the bottom of the vertical pipe 2 receives part of the wastewater separated by the filter screen 56. The collection bucket 62 is connected to the water pump 63 through the rigid pipe 61. The collected wastewater enters the water pump 63 along the rigid pipe 61. After the water pump 63 starts, it pressurizes the wastewater and delivers it to the hollow disc block 64. The hollow disc block 64 forms an annular flow channel inside, so that the water flow is evenly distributed to several inclined nozzles 65 at its bottom. The inclined nozzles 65 spray the pressurized wastewater in the form of high-pressure water flow to the top of the filter screen 56, thereby washing the outer surface of the filter screen 56, removing adhering impurities and keeping the filter screen 56 in a smooth state. This allows the entire device to continuously and stably achieve the synergistic effects of wastewater deceleration, flow equalization, filtration, solid-liquid separation, impurity discharge and filter screen 56 cleaning.
