Description

Technical Field

[0001] This utility model relates to the field of separation device technology, specifically to a separation device for urban sludge treatment. Background Technology

[0002] Separation devices for urban sludge treatment refer to devices used to separate solids and liquids in sludge generated during urban wastewater treatment projects. Their main function is to separate water from solid particles in sludge through physical, mechanical, or other technical means, thereby reducing the sludge's moisture content and volume for subsequent transportation or disposal.

[0003] A search revealed Chinese patent application CN202423233725.3, which proposes a separation device for urban sludge treatment, belonging to the field of sludge treatment technology. The key technical points include a separation box with a feeding hopper connected to its top. This application utilizes a separation mechanism where sludge slides smoothly down an inclined plate to an electric agitator. The electric agitator agitates the sludge, better separating solid particles and water, thus improving the separation effect. The sludge then falls onto the separation screen surface, where an electric extrusion cylinder squeezes out residual water, and a scraper cleans the surface sludge to prevent accumulation and maintain the extrusion. The separation screen acts as a crucial filter, effectively separating solid particles and wastewater. Importantly, a bottom reciprocating cleaning structure continuously cleans the separation screen, preventing clogging, ensuring good filtration performance, reducing the amount of wastewater carried by the sludge, achieving more thorough separation, and providing high-quality products for subsequent reprocessing, greatly improving the efficiency and effectiveness of the sludge treatment process.

[0004] In the aforementioned prior art, the sludge is first agitated by an electric agitator, then the water in the sludge is squeezed by an electric extrusion cylinder, and then the underside of the filter screen is scraped by a scraper. Finally, the sludge is discharged by the operation of a threaded rod. Although this physical treatment separation device can effectively separate sludge and sewage, the space at the agitation point is small when the sludge is agitated by the agitator, and the sludge is easy to accumulate there. This results in low agitation efficiency of the agitator, requiring a large amount of power to drive the agitator. At the same time, when the cleaning brush is used to clean the underside of the filter screen, the upper part of the filter screen is easily blocked by sludge, preventing sewage from falling through the filter screen and making subsequent sewage treatment inconvenient. This results in the discharged sewage carrying a large amount of sludge. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figures 1-4As shown, this utility model provides a technical solution: a separation device for urban sludge treatment, including a shell 1, a sewage outlet 11 fixedly connected to the lower end of the shell 1, a water pump 12 fixedly connected to the end of the shell 1 away from the sewage outlet 11, a drain pipe 13 fixedly connected to the end of the water pump 12 away from the shell 1, a feeding assembly 2 provided at the upper end of the shell 1, and the feeding assembly 2 including a sewage inlet 21 fixedly connected to the upper end of the shell 1, a separation pipe 22 fixedly connected to the inner side of the end of the shell 1 near the sewage inlet 21, and a feeding device provided at the end of the separation pipe 22 away from the sewage inlet 21. The feeding component 3 has a conveying component 4 at its lower end and a striking component 5 on its upper side. A sewage discharge component 6 is located on the lower side of one end of the conveying component 4, and a stirring component 7 is located on the inner side of the lower end of the outer shell 1. A feeding component 8 is located at the end of the outer shell 1 away from the sewage discharge component 6. By cooperating with the feeding component 2 and the feeding component 3, the separation efficiency of sludge and water can be effectively improved when separating sludge, and the low separation efficiency caused by sludge blockage can be reduced. At the same time, the separated wastewater can be treated to reduce the sludge content carried in the wastewater.

[0024] like Figure 3 As shown, the feeding assembly 3 includes a first motor 31 fixedly connected to the outer side of the housing 1 away from the inlet 21, and a threaded rod 32 fixedly connected through the output shaft of the first motor 31 through the housing 1. The outer side of the threaded rod 32 is inserted into the separation tube 22, and a first baffle 33 is sleeved on the outer side of the separation tube 22. The two ends of the first baffle 33 are fixedly connected to the housing 1, and a second baffle 34 is fixedly connected to the end of the first baffle 33 near the first motor 31. The upper end of the second baffle 34 is fixedly connected to the housing 1, and a guide plate 35 is fixedly connected to the inner side of the middle of the first baffle 33. The output shaft of the first motor 31 drives the threaded rod 32 to rotate, thereby conveying the sludge.

[0025] like Figure 3 As shown, the conveying assembly 4 includes a conveyor belt 41 disposed inside the first baffle 33, and a scraper 42 fixedly connected to the inner side of one end of the first baffle 33, with the upper end of the scraper 42 being fitted against the conveyor belt 41.

[0026] like Figure 3 As shown, the striking assembly 5 includes an electric telescopic rod 51 on the upper side of the conveyor belt 41, with the upper end of the electric telescopic rod 51 fixedly connected to the first baffle 33 and the lower end of the electric telescopic rod 51 fixedly connected to a striking plate 52. The operation of the electric telescopic rod 51 pushes the striking plate 52 to strike the sludge, causing the water contained therein to be squeezed out.

[0027] like Figure 3 As shown, the sewage discharge assembly 6 includes a mud guide plate 61 fixedly connected to the lower side of one end of the first baffle 33, and a mud discharge port 62 is provided inside the outer shell 1 at the end near the mud guide plate 61.

[0028] like Figure 3 As shown, the stirring assembly 7 includes a second motor 71 fixedly connected to the middle of the lower side of the first baffle 33, and a stirring rod 72 fixedly connected to the output shaft of the second motor 71. By starting the second motor 71, its output shaft drives the stirring rod 72 to rotate, which facilitates the stirring of sewage and flocculant to make them blend quickly.

[0029] like Figure 3 As shown, the feeding assembly 8 includes a liquid storage tank 81 fixedly connected to the lower side of the first baffle 33 away from the mud guide plate 61, and a liquid inlet 82 fixedly connected to one end of the liquid storage tank 81. The end of the liquid inlet 82 away from the liquid storage tank 81 is disposed through the outer shell 1, and an electronic valve 83 is fixedly connected to the lower side of one end of the liquid storage tank 81. When the electronic valve 83 is opened, the flocculant in the liquid storage tank 81 drops out, and then the flocculant is injected into the liquid storage tank 81 for storage through the liquid inlet 82.

[0030] Working principle: When treating sludge, the first motor 31 and conveyor belt 41 are started first. After the first motor 31 starts, the output shaft drives the threaded rod 32 to rotate. Then, the sludge is injected into the separation pipe 22 through the inlet 21. At this time, the rotation of the threaded rod 32 is used to transport the injected sludge. During the transportation process, the sludge is impacted by the rotation of the threaded rod 32, causing the wastewater in the sludge to be discharged through the groove at the lower end of the separation pipe 22. The discharged wastewater falls under the guidance of the guide plate 35. The falling wastewater is blocked by the threaded rod 32 and the first baffle 33 and falls to the lower end of the outer shell 1 for collection. The sludge that is being transported falls onto the conveyor belt 41 under the guidance of the first baffle 33 and the second baffle 34. The operation of the conveyor belt 41 is used for secondary transportation. During the transportation process, multiple sets of electric telescopic conveyors are activated in sequence. After the electric telescopic rod 51 is started, it pushes the striking plate 52 to move down intermittently to strike the sludge. After being struck, the sewage in the sludge falls through the conveyor belt 41 and then through the slot at the lower end of the first baffle 33 to the lower end of the outer shell 1 for collection. Then the sludge is scraped off by the scraper 42 and guided by the mud guide plate 61 and discharged through the mud discharge port 62. The collected sewage first drops the flocculant in the storage tank 81 by opening the electronic valve 83. Then the second motor 71 is started so that its output shaft drives the stirring rod 72 to rotate and stir the sewage and flocculant to mix them and allow the sludge in the sewage to settle. Finally, the water pump 12 is started to extract the clean water at the top of the sewage and discharge it through the drain pipe 13. After the clean water is pumped to a certain height, the sewage outlet 11 is opened to discharge the last sewage for subsequent processing.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
