Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of sewage pipes, and particularly relates to a sewage pipe resistant to mixed oil stains. Background Art
[0002] Mixed oil stains are pollutants formed by mixing various different types of oil substances and other impurities. Their composition is quite complex. The oil substances include mineral oils such as petroleum, diesel, and lubricating oil; animal and vegetable oils such as common edible oils and fats; and synthetic oils such as silicone oil and ester oils. In mixed oil stains from different sources, the proportion and types of various oils vary greatly. At the same time, it also contains impurities such as dust, soil, metal chips, moisture, and other organic and inorganic substances, which are mostly mixed in during the use, storage, or transportation of oils. Mixed oil stains have distinct characteristics. Due to their diverse composition, their properties are extremely complex. Different oils have unique physical and chemical properties such as viscosity, density, flash point, and solubility. After mixing, these properties interact with each other, making it difficult to accurately predict and control the overall properties of mixed oil stains. Generally, it has high viscosity, which stems from the viscosity of the oils themselves, and the interaction of the components after mixing further increases the viscosity, making it extremely easy to adhere to the surface of objects and difficult to clean and remove. To a certain extent, mixed oil stains also have relative stability. The oil substances are well soluble in each other, and the impurities can also play a certain stabilizing role. However, under specific conditions such as high temperature, strong acid or strong alkali environment, or long-term exposure to air, decomposition, oxidation and other changes may occur. Mixed oil stains require special sewage pipes for discharge.
[0003] In the case of existing sewage pipes, after long-term discharge of mixed oil stains, it is easy for the mixed oil stains to adhere to the inner wall of the pipe, which affects the discharge volume of the sewage pipe, and it is easy to have backflow when discharging sewage. After the sewage pipe is used for a period of time, it needs to be disassembled and cleaned. Some sewage pipes are equipped with a cleaning drive component, which requires external power for cleaning, and is not energy-saving and environmentally friendly. Therefore, we propose a sewage pipe resistant to mixed oil stains to solve the above problems. Summary of the Invention

[0013] The technical effects achieved by the present invention are as follows: When the water inflow of the connecting pipe is small and the flow rate is low, due to the addition of counterweights on the two first water baffle plates, the small water inflow and low flow rate cannot effectively impact the first water baffle plates, and the two second water baffle plates will not open. The sewage entering the connecting pipe mainly falls through the first water inlet. At this time, the sewage is mainly concentrated on one side of the water inlet driving mechanism. The sewage impacts the driving fan blades, and multiple driving fan blades rotate counterclockwise. At this time, the driving fan blades respectively deflect two displacement plates, and the two displacement plates respectively perform reverse displacements in the vertical direction, causing the displacement plates to drive multiple first oil stain cleaning needles to move in the vertical direction, enabling the multiple first oil stain cleaning needles to scrape the mixed oil stains adhering to the inner wall of the sewage discharge main pipe, preventing the mixed oil stains from accumulating on the inner wall of the sewage discharge main pipe and affecting the drainage volume of the sewage discharge main pipe. The cooperation of the first return spring and the first moving rod can reset the first arc-shaped scraper, enabling the first arc-shaped scraper to perform repeated cleaning. The rotation of the driving fan blades can drive the rotation of the first rotating shaft, thereby driving the rotation of the driving gear and driving the second arc-shaped scraper to move downward in the vertical direction, enabling the second oil stain cleaning needle to clean the inner wall of the sewage discharge main pipe; the length of the driving chain is relatively long; When the water inflow of the connecting pipe is large and the flow rate is high, the sewage with a large water inflow and high flow rate effectively impacts the first water baffle plates, thereby offsetting the gravity of the counterweights, causing the first water baffle plates to rotate with the cooperation of the second rotating shafts, causing the two second water baffle plates to move in the opposite direction, reducing the occlusion of the two second water baffle plates on the second water inlet, and enabling the sewage to mainly fall through the second water inlet. The sewage with a large water inflow and high flow rate impacts the water receiving plate and the water guiding plate, thereby offsetting the elastic force of the second return spring, causing the working position of the third water baffle plate to drop. The water guiding plate drives the fourth water baffle plate to move under the action of the water flow, offsetting the elastic force of the third return spring, causing the fourth water baffle plate to be closer to the second water inlet, concentrating the water flow in the direction of the second water inlet, increasing the water inflow of the second water inlet. The sewage passing through the second water inlet is mainly concentrated on the other side of the water inlet driving mechanism. The sewage impacts the driving fan blades. Contrary to the small water inflow, the driving fan blades drive the first rotating shaft to rotate clockwise under the action of the water flow, and can also cause the displacement plates to drive multiple first oil stain cleaning needles to move in the vertical direction, enabling the multiple first oil stain cleaning needles to scrape the mixed oil stains adhering to the inner wall of the sewage discharge main pipe. At this time, the driving gear rotates, driving the second arc-shaped scraper to move downward in the vertical direction, enabling the second oil stain cleaning needle to clean the inner wall of the sewage discharge main pipe. Appropriately adjusting the sewage flow rate entering the connecting pipe can more effectively clean the mixed oil stains in the sewage discharge main pipe. Without additional driving components, the internal oil stains of the sewage discharge pipe can be cleaned, preventing the mixed oil stains from accumulating on the inner wall of the sewage discharge pipe, ensuring the drainage volume of the sewage discharge pipe. The connecting pipe that is prone to adhering oil stains can be removed for cleaning, effectively reducing the manual cleaning operation of the sewage discharge pipe. Description of the Drawings

A driven wheel 39 is provided at one end of the driving chain 29 far from the driving gear 28, and the driven wheel 39 is connected to the inner wall of the sewage main pipe 1 through a rotating shaft.

A water guiding plate 38 is fixedly connected to the end of the third water blocking plate 32 far from the second sliding block 35.
[0025] In the present invention, when the sewage pipe needs to be used, the connecting pipe 2 is connected to the drain pipe mixed with oil and grease (the drain pipe is an external drain pipe mixed with oil and grease, not recorded in the solution), and the bottom of the sewage main pipe 1 is connected to an external oil and grease collection and treatment device (the external oil and grease collection and treatment device is a conventional sewage collection device or treatment device); When the water inflow of the docking pipe 2 is small and the flow rate is low, since the counterweights 27 are installed on the two first water baffles 24, the water inflow is small and the flow rate is low, and the first water baffles 24 cannot be effectively impacted, and the two second water baffles 30 will not open. The sewage entering the docking pipe 2 mainly falls through the first water inlet 4. At this time, the sewage is mainly concentrated on one side of the water inlet drive mechanism, and the sewage impacts the driving blades 8. The multiple driving blades 8 rotate in the counterclockwise direction. At this time, the driving blades 8 respectively move the two displacement plates 15, and the two displacement plates 15 respectively reversely displace in the vertical direction, so that the displacement plates 15 drive the multiple first oil cleaning needles 10 to move in the vertical direction, so that the multiple first oil cleaning needles 10 scrape the mixed oil adhered to the inner wall of the sewage main pipe 1, so as to prevent the mixed oil from accumulating on the inner wall of the sewage main pipe 1 and affecting the sewage main pipe 1. The first return spring 14 cooperates with the first moving rod 11 to reset the first arc scraper 9, so that the first arc scraper 9 can be repeatedly cleaned, and the driving blade 8 can drive the first rotating shaft 6 to rotate, thereby driving the driving gear 28 to rotate, and driving the second arc scraper 16 to move downward in the vertical direction, so that the second oil cleaning needle 37 cleans the inner wall of the sewage main pipe 1 (the driving chain 29 is long, and the second arc scraper 16 moves vertically with the movement of the driving chain 29. When the connection point between the driving chain 29 and the second arc scraper 16 moves to the driven wheel 39, the second arc scraper 16 will be slightly displaced laterally under the drive of the driving chain 29, and the second arc scraper 16 will press against the inner wall of the sewage main pipe 1, so that the driving chain 29 stops rotating, and then the first rotating shaft 6 stops rotating); When the water inflow of the connecting pipe 2 is large and the flow rate is high, the sewage with a large water inflow and a high flow rate effectively impacts the first water baffle 24, thereby offsetting the gravity of the counterweight 27, causing the first water baffle 24 to rotate under the cooperation of the second rotating shaft 25, making the two second water baffles 30 move in opposite directions, reducing the occlusion of the two second water baffles 30 on the second water inlet 5, enabling the sewage to mainly fall through the second water inlet 5. The sewage with a large water inflow and a high flow rate impacts the water receiving plate 23 and the water guiding plate 38, thereby offsetting the elastic force of the second return spring 22, causing the working position of the third water baffle 32 to drop. The water guiding plate 38 drives the fourth water baffle 34 to move under the action of the water flow, offsetting the elastic force of the third return spring 36, making the fourth water baffle 34 closer to the second water inlet 5, concentrating the water flow in the direction of the second water inlet 5, increasing the water inflow of the second water inlet 5. The sewage passing through the second water inlet 5 is mainly concentrated on the other side of the water inlet driving mechanism, and the sewage impacts the driving fan blade 8. Contrary to the case of a small water inflow, the driving fan blade 8 drives the first rotating shaft 6 to rotate clockwise under the action of the water flow, and similarly, the displacement plate 15 drives a plurality of first oil cleaning needles 10 to move in the vertical direction, enabling the plurality of first oil cleaning needles 10 to scrape the mixed oil adhered to the inner wall of the sewage main pipe 1. At this time, the driving gear 28 rotates, driving the second arc-shaped scraper 16 to move downward in the vertical direction, enabling the second oil cleaning needle 37 to clean the inner wall of the sewage main pipe 1. Appropriately adjusting the sewage flow rate entering the connecting pipe 2 can more effectively clean the mixed oil in the sewage main pipe 1, clean the internal oil of the sewage pipe without additionally adding a driving component, prevent the mixed oil from accumulating on the inner wall of the sewage pipe, ensure the drainage volume of the sewage pipe, and the connecting pipe 2 that is prone to adhering oil can be removed for cleaning, effectively reducing the manual cleaning operation of the sewage pipe.
[0026] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention are implemented according to the conventional means in the art without special instructions and limitations.
