Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, in particular to a sewage treatment device suitable for urban sewage treatment. Background Art

[0002] Urban sewage is a mixture of domestic sewage, industrial wastewater and runoff sewage within urban areas. Since urban sewage contains a large amount of harmful substances, in order to avoid the impact of sewage discharge on the environment, sewage needs to be treated.

[0003] The patent with announcement number CN114249363B discloses a floating sludge collection device for sewage treatment pools for urban environmental protection, including a floating sludge collection box, a net-releasing device is installed at the bottom of one side of the floating sludge collection box, and a water surface robot is externally arranged on one side of the net-releasing device. The water surface robot includes a shell, a driving component, multiple springs three, multiple guide columns, a movable plate, a reversing slurry, an iron block and an electromagnetic component module. A circular hole one is opened on the top of the shell, and circular holes two are opened at the top positions of the outer walls of both ends of the shell. The driving component is arranged between the circular hole one and the two circular holes two, and multiple guide holes are opened on the outer wall of one end of the movable plate. The patent can make the retaining net be continuously moved to form waves, and push the blocked floating sludge into the floating sludge collection box, thereby improving the collection efficiency. At the same time, the floating sludge suspended in the sewage contacts the retaining net, is vibrated and floats on the water surface for easy collection.

[0004] However, the above technical solution still has the following deficiencies in practical application: Since floating objects such as sludge often appear on the surface of sewage during sewage treatment, which will have a certain impact on sewage treatment, the above technical solution sets a retaining net at the sewage pool, and uses the retaining net to push the blocked floating sludge into the collection box to collect the floating sludge on the water surface. Although this method can collect the floating sludge on the water surface, the floating sludge needs to move to the retaining net. In some cases, the movement trajectory of the floating sludge on the water surface is irregular, which will cause the floating sludge to be unable to move accurately to the retaining net, thereby affecting the normal collection of the floating sludge on the water surface. It is also troublesome to collect the floating sludge by frequently changing the position of the retaining net. Summary of the invention

[0016] The beneficial effects of the present invention are as follows: 1. The sewage treatment equipment suitable for urban sewage treatment described in the present invention utilizes a radial gathering and conveying mechanism to remove floating objects such as floating mud on the water surface, thereby ensuring the sewage treatment effect. Moreover, during the entire removal process, the floating mud plate and the floating mud cloth can push the floating mud on the water surface of the sewage pool without dead angles, ensuring that the floating mud in all directions on the water surface can be moved to the conveying cylinder, thereby improving the comprehensiveness of the push, and avoiding the situation in which the floating mud cannot be accurately moved to the retaining net due to the irregular movement trajectory of the floating mud when the floating mud on the water surface is collected by the retaining net, thereby affecting the normal collection of the floating mud on the water surface. In addition, the radial gathering and conveying mechanism can realize the removal of floating mud and other floating objects on the water surface, thereby ensuring the sewage treatment effect. The angle track anti-adhesion pushing component, when the scum plate and the scum cloth move to the conveying cylinder, drives the elastic plate to move downward along the surface of the scum plate, and the elastic plate pushes down the plastic bag adhering to the scum plate. At the same time, when the elastic plate is separated from the scum plate, the elastic plate will move laterally under the action of the spring, so that the elastic plate moves along a right-angle track, and pushes the scraped plastic bag to the conveying cylinder, so that the plastic bag can smoothly contact with the conveying blades and be conveyed, thereby avoiding the scum plate and the scum cloth from contacting and squeezing the plastic bag when they descend, causing the plastic bag to hang on the bottom of the scum plate or the scum cloth, resulting in the plastic bag being unable to move smoothly to The inner cavity of the conveying cylinder affects the normal collection, and when the floating objects are pushed to the conveying cylinder by the scum plate and the scum cloth, the cover body is driven to move upward to cover the bottom of the conveying cylinder. At this time, multiple scum plates can be away from the conveying cylinder and push the subsequent floating objects, avoiding the situation that the scum plate is always needed to block the floating objects at the conveying cylinder during the conveying of the floating objects by the conveying blades, thereby affecting the pushing of the subsequent floating objects, further improving the removal efficiency of the floating objects, and using negative pressure to push the auxiliary component, when the scum plate moves, suction is generated at the bottom opening of the elastic plate, The upper end of the plastic bag is adsorbed, and when the elastic plate is about to enter the water and detach from the scum plate, the suction force is no longer generated at the bottom opening of the elastic plate, and the elastic plate can push the plastic bag toward the conveying tube, so that the plastic bag is smoothly pushed into the conveying tube. In the process of the elastic plate scraping the plastic bag from the scum plate, the plastic bag will remain stable and will not fall off prematurely until the plastic bag is successfully pushed into the conveying tube by the elastic plate, thereby avoiding the situation where the plastic bag falls prematurely when the elastic plate scrapes the plastic bag downwards, and moves away from the conveying tube under the action of water surface fluctuations, and thus cannot be smoothly conveyed, causing trouble.

[0017] 2. The sewage treatment equipment suitable for urban sewage treatment described in the present invention can stir the sewage and the agents by driving the stirring rod to rotate through the motor when flocculants, dephosphorization agents and other agents are added into the sewage pool and react with the sewage, thereby intensifying the reaction between the sewage and the agents and improving the sewage treatment efficiency.

[0027] The outer ring of the bottom plate 27 is sleeved and slidably connected with the cover body 20, and one side of the lower end surface of the bottom plate 27 is fixedly connected with a motor 4 25, and the motor 4 25 is provided with a waterproof shell. The output end of the motor 4 25 is fixedly connected with a threaded rod 4 26, and the threaded rod 4 26 is threadedly connected to one side of the cover body 20.

[0028] A threaded rod 9 is threadedly connected to one side of the lower end of the mounting plate 5, and both ends of the threaded rod 9 are rotatably arranged on the sewage pool 1.

[0029] The mounting plate 5 is also provided with a negative pressure pushing auxiliary component; The negative pressure push auxiliary component includes a fan 6 fixedly connected to one side of the upper end surface of the mounting plate 5, the air inlet end of the fan 6 is connected to a connecting pipe 13, the connecting pipe 13 penetrates the upper side of the mounting plate 5, and the lower end of the connecting pipe 13 is connected to and fixedly connected to an annular tube 7, a plurality of hoses 15 are connected to the annular tube 7, an air inlet is provided on the lower side of the elastic plate 14, and one end of the hose 15 is connected to the air inlet of the elastic plate 14.

[0030] Specifically, since floating objects such as floating mud often appear on the surface of sewage during sewage treatment, which will have a certain impact on sewage treatment, the prior art sets a retaining net at the sewage pool 1, and uses the retaining net to push the blocked floating mud into the collection box to collect the floating mud on the water surface. Although this method can collect the floating mud on the water surface, the floating mud needs to move to the retaining net. In some cases, the movement trajectory of the floating mud on the water surface is irregular, which will cause the floating mud to be unable to move accurately to the retaining net, thereby affecting the normal collection of the floating mud on the water surface. It is also troublesome to collect the floating mud by frequently changing the position of the retaining net. Therefore, in order to solve the above problems, when the present embodiment is used, the sewage to be treated is added into the sewage pool 1, and the scum plate 10 in the initial state is attached to the inner wall of the sewage pool 1, and the sewage pool 1 is circular; Flocculants, dephosphorizing agents and other agents are added into the sewage pool 1 and react with the sewage. When floating objects such as sludge appear on the sewage surface, the motor 8 drives the threaded rod 9 to rotate to lower the mounting plate 5, so that the scum plate 10 and the scum cloth 11 are submerged above the water surface. Then the motor 6 36 is started, and the output ends on both sides of the motor 6 36 respectively drive the threaded rod 5 32 and the bevel gear 2 35 to rotate, so that under the action of the bevel gear 1 34, multiple threaded rods 5 32 and the bevel gear 2 35 rotate at the same time, and multiple scum plates 10 move radially on the threaded rod 2 12 and the sliding rod 1 13 at the same time, and the scum plates 10 and the scum cloth 11 approach the conveying cylinder 3, and the size of the scum cloth 11 will change in real time with the movement of the scum plate 10. Since the scum plate 10 starts to move from the edge of the sewage pool 1, no matter where the sludge is on the water surface of the sewage pool 1, it will The scum plate 10 or scum cloth 11 contacts with the moving scum plate 10 or scum cloth 11 until the scum is pushed above the bottom plate 27. At this time, the motor 7 37 can drive the gear 1 38 to rotate, so that the gear 2 39, the sleeve 30, and the conveying blade 31 rotate synchronously. The conveying blade 31 can convey the scum upward until the scum is discharged to the outside of the sewage pool 1 through the conveying pipe 4, thereby realizing the removal of floating objects such as scum on the water surface and ensuring the sewage treatment effect. In addition, during the whole removal process, the scum plate 10 and the scum cloth 11 can push the scum on the water surface of the sewage pool 1 without dead angles, ensuring that the scum in all directions on the water surface can be moved to the conveying cylinder 3, improving the comprehensiveness of the push, and avoiding the situation that when the scum on the water surface is collected by the retaining net, the scum cannot be accurately moved to the retaining net due to the irregular movement trajectory of the scum, which affects the normal collection of the scum on the water surface. Although the above method can be used to remove floating objects such as floating mud on the water surface, the floating objects may include plastic bags. When the plastic bag is at the edge of the sewage pool 1, the scum plate 10 and the scum cloth 11 will come into contact with and squeeze the plastic bag when they descend, so that the plastic bag may be hung on the bottom of the scum plate 10 or the scum cloth 11, which will cause the plastic bag to be unable to move smoothly to the inner cavity of the conveying cylinder 3, affecting normal collection. Therefore, in order to avoid this situation, when the scum plate 10 and the scum cloth 11 move to the conveying cylinder 3, the scum cloth 11 is at its smallest size and the edges of the adjacent scum plates 10 are fitted together, so that the plastic bag can only be hung on the bottom of the scum plate 10 at this time, and then the motor 2 18 drives the threaded rod 3 19 to rotate to make the connecting plate 16 When the scum plate 10 and the scum cloth 11 are lowered, the elastic plate 14 moves downward along the surface of the scum plate 10, and the elastic plate 14 pushes down the plastic bag hanging on the scum plate 10. At the same time, when the elastic plate 14 is separated from the scum plate 10, the elastic plate 14 moves laterally under the action of the spring 24, and pushes the scraped plastic bag to the conveying cylinder 3, so that the plastic bag can smoothly contact with the conveying blade 31 and be conveyed, and then the motor 3 21 drives the reset rod 22 to rotate, and the push block 17 is pushed to reset the elastic plate 14, thereby avoiding the scum plate 10 and the scum cloth 11 from contacting and squeezing the plastic bag when the scum plate 10 and the scum cloth 11 are lowered, resulting in the plastic bag hanging on the bottom of the scum plate 10 or the scum cloth 11, which makes the plastic bag unable to smoothly move to the inner cavity of the conveying cylinder 3, affecting the normal collection; Furthermore, when the floating objects are in the conveying cylinder 3, if there are too many floating objects, it will take a longer time to convey all the floating objects to the conveying pipe 4. Therefore, in order to prevent the floating objects from moving out from the bottom of the conveying cylinder 3 during transportation, the scum plate 10 needs to be always in the conveying cylinder 3 to enclose the floating objects in the conveying cylinder 3 to prevent the floating objects from moving out of the conveying cylinder 3 again. When all the floating objects are discharged through the conveying pipe 4, the scum plate 10 can be driven away from the conveying cylinder 3 to carry out subsequent pushing work. This will cause the scum plate 10 to fail to work normally during the period when the floating objects are conveyed by the conveying blades 31. Thus, the removal of the floating objects that float up subsequently is affected. Therefore, in order to avoid this situation, when the floating objects are pushed to the conveying cylinder 3 by the scum plate 10 and the scum cloth 11, the motor 25 drives the threaded rod 26 to rotate, so that the cover 20 moves upward to cover the bottom of the conveying cylinder 3. At this time, the multiple scum plates 10 can be away from the conveying cylinder 3 and push the floating objects that float up subsequently, avoiding the situation that the scum plate 10 needs to be always at the conveying cylinder 3 during the conveying of the floating objects by the conveying blades 31, thereby affecting the pushing of the floating objects that float up subsequently, and further improving the removal efficiency of the floating objects. When the elastic plate 14 scrapes the plastic bag downward, the plastic bag may fall off in advance. At this time, the elastic plate 14 has not yet separated from the scum plate 10. The plastic bag that falls off in advance may move away from the conveying cylinder 3 under the action of the water surface fluctuation, and cannot be smoothly conveyed, causing trouble. Therefore, in order to avoid this situation, when the scum plate 10 moves, the hose 15 will also be deformed. When the elastic plate 14 contacts the plastic bag, the fan 6 is started. Under the action of the connecting pipe 13, the annular pipe 7, and the hose 15, suction is generated at the bottom opening of the elastic plate 14 to adsorb the upper end of the plastic bag. When the elastic plate 14 is When the plastic bag enters the water and leaves the scum plate 10, the suction force is no longer generated at the bottom opening of the elastic plate 14, and the elastic plate 14 can push the plastic bag toward the conveying tube 3, so that the plastic bag is smoothly pushed into the conveying tube 3. During the process of the elastic plate 14 scraping the plastic bag off the scum plate 10, the plastic bag will remain stable and will not fall off prematurely until the plastic bag is smoothly pushed into the conveying tube 3 by the elastic plate 14, thereby avoiding the situation where the plastic bag falls prematurely when the elastic plate 14 scrapes the plastic bag downwards, and moves away from the conveying tube 3 under the action of water surface fluctuations, and thus cannot be smoothly conveyed, causing trouble.

[0031] In this embodiment, Figure 8 As shown, a drain pipe 2 is provided at one side of the bottom of the sewage pool 1, and a valve is provided on the drain pipe 2.

[0032] Specifically, after the sewage treatment is completed, the sewage can be discharged by opening the valve on the drain pipe 2.

[0033] A stirring rod 29 is rotatably arranged in the middle of the lower end of the inner cavity of the sewage pool 1, and a motor 5 28 is fixedly connected to the middle of the lower end surface of the sewage pool 1, and the output end of the motor 5 28 is fixedly connected to the bottom of the stirring rod 29.

[0034] Specifically, when flocculants, dephosphorizing agents and other chemicals are added to the sewage pool 1 and react with the sewage, the sewage and the chemicals can be stirred by driving the stirring rod 29 to rotate through the motor 28, thereby intensifying the reaction between the sewage and the chemicals, which is beneficial to improving the sewage treatment efficiency.

[0035] Working principle: The sewage to be treated is added into the sewage pool 1, and the scum plate 10 in the initial state is attached to the inner wall of the sewage pool 1, and the sewage pool 1 is circular; Flocculants, dephosphorizing agents and other chemicals are added into the sewage pool 1 and react with the sewage. The sewage and the chemicals can be stirred by rotating the stirring rod 29 driven by the motor 5 28, thereby intensifying the reaction between the sewage and the chemicals, which is beneficial to improving the sewage treatment efficiency. When floating objects such as sludge appear on the sewage surface, the motor 8 drives the threaded rod 9 to rotate to lower the mounting plate 5, so that the sludge plate 10 and the sludge cloth 11 are submerged above the water surface, and then the motor 6 36 is started. The output ends on both sides of the motor 6 36 respectively drive the threaded rod 5 32 and the bevel gear 2 35 to rotate, so that under the action of the bevel gear 1 34, multiple threaded rods 5 32 and bevel gear 2 35 rotate at the same time, and multiple sludge plates 10 move radially on the threaded rod 2 12 and the slide rod 1 13 at the same time, and the sludge plates 10 and the sludge cloth 11 approach the conveying cylinder 3, and the size of the sludge cloth 11 will change in real time with the movement of the sludge plate 10. Since the sludge plate 10 starts to move from the edge of the sewage pool 1, no matter where the sludge is on the water surface of the sewage pool 1, it will contact the moving sludge plate 10 or sludge cloth 11 contacts until the floating mud is pushed above the bottom plate 27. At this time, the motor 7 37 can drive the gear 1 38 to rotate, so that the gear 2 39, the sleeve 30, and the conveying blade 31 can rotate synchronously. The conveying blade 31 can convey the floating mud upward until the floating mud is discharged to the outside of the sewage pool 1 through the conveying pipe 4, thereby realizing the removal of floating mud and other floating objects on the water surface, ensuring the sewage treatment effect, and in the whole removal process, the floating mud plate 10 and the floating mud cloth 11 can push the floating mud on the water surface of the sewage pool 1 without dead angles, ensuring that the floating mud in all directions on the water surface can be moved to the conveying cylinder 3, improving the comprehensiveness of the push, and avoiding the situation that when the floating mud on the water surface is collected by the retaining net, the floating mud cannot be accurately moved to the retaining net due to the irregular movement trajectory of the floating mud, which affects the normal collection of the floating mud on the water surface; Although the above method can be used to remove floating objects such as floating mud on the water surface, the floating objects may include plastic bags. When the plastic bags are at the edge of the sewage pool 1, the scum plate 10 and the scum cloth 11 will come into contact with and squeeze the plastic bags, which may cause the plastic bags to hang on the bottom of the scum plate 10 or the scum cloth 11, thereby causing the plastic bags to be unable to move smoothly to the inner cavity of the conveying cylinder 3, affecting normal collection. Therefore, in order to avoid this situation, when the scum plate 10 and the scum cloth 11 move to the conveying cylinder 3, the scum cloth 11 is at its smallest size and the edges of the adjacent scum plates 10 are in contact with each other, the plastic bags can only hang on the bottom of the scum plate 10 at this time, and then the plastic bags can be collected by the conveying cylinder 3. When the motor 2 18 drives the threaded rod 3 19 to rotate, the connecting plate 16 is lowered, and the elastic plate 14 moves downward along the surface of the scum plate 10, and the elastic plate 14 pushes down the plastic bag hanging on the scum plate 10. At the same time, when the elastic plate 14 is separated from the scum plate 10, the elastic plate 14 moves laterally under the action of the spring 24, and pushes the scraped plastic bag to the conveying cylinder 3, so that the plastic bag can smoothly contact with the conveying blade 31 and be conveyed, and then the motor 3 21 drives the reset rod 22 to rotate, and pushes the push block 17 to reset the elastic plate 14, thereby avoiding the scum plate 10 and the scum cloth 11 from contacting and squeezing the plastic bag when they descend. The plastic bag hangs on the bottom of the scum plate 10 or the scum cloth 11, which makes it impossible for the plastic bag to move smoothly to the inner cavity of the conveying cylinder 3, affecting the normal collection; and when the floating objects are in the conveying cylinder 3, if the number of floating objects is too large, it will take a longer time to convey all the floating objects to the conveying pipe 4. Therefore, in order to avoid the floating objects from moving out of the bottom of the conveying cylinder 3 during transportation, the scum plate 10 is always required to be at the conveying cylinder 3 to block the floating objects at the conveying cylinder 3 to prevent the floating objects from moving out of the conveying cylinder 3 again. When all the floating objects are discharged through the conveying pipe 4, the scum plate 10 can be driven away from the conveying cylinder 3 for subsequent pushing work, which will cause the floating objects to move out of the conveying cylinder 3. During the period when the floating objects are transported by the conveying blades 31, the scum plate 10 cannot work normally, thereby affecting the removal of the floating objects that float up subsequently. Therefore, in order to avoid this situation, when the floating objects are pushed to the conveying cylinder 3 by the scum plate 10 and the scum cloth 11, the motor 25 drives the threaded rod 26 to rotate, so that the cover body 20 moves upward to cover the bottom of the conveying cylinder 3. At this time, multiple scum plates 10 can be away from the conveying cylinder 3 and push the floating objects that float up subsequently, avoiding the situation that the scum plate 10 needs to be always at the conveying cylinder 3 during the period when the floating objects are transported by the conveying blades 31, thereby affecting the pushing of the floating objects that float up subsequently, and further improving the removal efficiency of the floating objects;When the elastic plate 14 scrapes the plastic bag downward, the plastic bag may fall off in advance. At this time, the elastic plate 14 has not yet separated from the scum plate 10. The plastic bag that falls off in advance may move away from the conveying cylinder 3 under the action of the water surface fluctuations, and cannot be smoothly conveyed, causing trouble. Therefore, in order to avoid this situation, when the scum plate 10 moves, the hose 15 will also be deformed. When the elastic plate 14 contacts the plastic bag, the fan 6 is started. Under the action of the connecting pipe 13, the annular pipe 7, and the hose 15, suction is generated at the bottom opening of the elastic plate 14 to adsorb the upper end of the plastic bag. When the elastic plate 14 is about to enter the water and separate from the scum plate 10, the plastic bag is sucked. When the elastic plate 14 is pulled down, the bottom opening of the elastic plate 14 no longer generates suction, and the elastic plate 14 can push the plastic bag toward the conveying cylinder 3, so that the plastic bag is smoothly pushed into the conveying cylinder 3. During the process of the elastic plate 14 scraping the plastic bag off the scum plate 10, the plastic bag will remain stable and will not fall off in advance until the plastic bag is smoothly pushed into the conveying cylinder 3 by the elastic plate 14, thereby avoiding the situation that when the elastic plate 14 scrapes the plastic bag downward, the plastic bag falls off in advance and moves away from the conveying cylinder 3 under the action of water surface fluctuations, and thus cannot be smoothly conveyed, causing trouble. When the sewage treatment is completed, the sewage can be discharged by opening the valve on the drain pipe 2. ;
