Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaning technology, specifically to a small vacuum cleaning system. Background Technology

[0002] Traditional manhole dredging involves workers using long-armed baskets to reach into the manholes and retrieve silt, which is inefficient, polluting, and ineffective. Therefore, developing a dredging device that can replace manual manhole dredging is an urgent need for the development of municipal engineering technology and for building modern civilized cities.

[0003] Patent document CN209596635U discloses a vacuum sludge suction device, including a water storage tank, a truss, a vacuum tank, a conveying pipe, a diversion pipe, a sludge suction pipe, a sludge suction nozzle, a main inlet pipe, branch inlet pipes, a vacuum pump, a sludge discharge valve, and an early warning mechanism. Water is pumped into the sludge suction nozzle through the main inlet pipe and branch inlet pipes to flush and dilute the sludge. The vacuum tank is evacuated through an interface pipe. The sludge mixed with water enters the sludge suction pipe through the sludge suction nozzle, and then enters the vacuum tank through the diversion pipe and conveying pipe. As the sludge in the vacuum tank increases, a float moves upward with the sludge until a sealing head extends into the interface pipe and blocks it, at which point the vacuum pump stops working, completing the sludge suction. The sludge discharge valve is used to discharge the sludge from the vacuum tank. However, this patent cannot completely solve the existing technical problems, nor can it meet the needs of this utility model. Utility Model Content

[0004] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a small vacuum cleaning system.

[0005] The small vacuum sludge suction system provided by this utility model is characterized by comprising: a vacuum pump, a connecting pipe, and a mud-water separation tank; the vacuum pump and the mud-water separation tank are connected through the connecting pipe;

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] This solution provides a small-scale vacuum sewage suction system that uses a two-layer filtration method to treat mud-water mixtures: a bar screen filter and a quartz sand filter. First, the bar screen effectively separates flexible materials such as branches, plastic bags, and stones from larger lumps in the mud-water mixture. Second, quartz sand is used as the filter medium to filter out residual small particulate solids in the mud-water mixture. This two-layer filtration method effectively traps and removes suspended solids, organic matter, colloidal particles, and flocculated objects from the sewage, ultimately reducing water turbidity and purifying the water quality. The separated water is discharged back into the manhole through the drain outlet. The system operates with simultaneous suction and discharge, resulting in high sewage treatment efficiency and excellent performance. It is highly adaptable and can meet the sewage treatment needs of various applications, including pumping stations, roads, streets, and residential areas. Attached Figure Description

[0031] Example

[0032] like Figure 1 and Figure 2This utility model provides a small vacuum sewage suction system, which consists of a vacuum pump 1, a connecting pipe 2, and a mud-water separation tank 3. The mud-water separation tank 3 consists of an air intake 4, a magnetic flap level gauge 5, a water inlet 6, a filter media 7, a mud inlet 8, a grid 9, a mud discharge outlet 10, a water storage tank 11, and a drain outlet 12. Vacuum pump 1 is a 7.5KW, 380V high-flow water ring vacuum pump that adsorbs air from the mud-water separation tank 3, creating a vacuum. Utilizing the pressure difference between the inside and outside of the mud-water separation tank 3, wastewater flows smoothly into the tank from the sludge inlet 8. Connecting pipe 2 is a 2.5-inch steel wire braided hose, 3mm thick. One end of connecting pipe 2 connects to the air inlet of vacuum pump 1, and the other end connects to the suction port 4. All connections are secured with strong clamps. The mud-water separation tank 3 is constructed of 6mm carbon steel and is entirely sealed and corrosion-resistant. The suction port 4 is constructed of 4mm carbon steel and welded to the upper part of the water storage tank 11. A magnetic level gauge 5 is used for level measurement and control in the mud-water separation device and is bolted to a pre-installed bracket on the outside of the mud-water separation tank 3. The water inlet 6 is made of 4-inch stainless steel. A steel pipe, connected to a suction pipe via a ring clamp, allows the mud-water mixture to enter the mud-water separation device through this inlet. Filter media 7 uses 2mm quartz sand, enabling secondary filtration and separation of the mud-water mixture. The inlet 8 uses a 4-inch stainless steel pipe, bolted to the side of the mud-water separation tank 3 and connected to the suction pipe via a ring clamp, allowing the mud-water mixture to enter the mud-water separation device through this inlet. The grid 9 uses a mesh structure made of 304 stainless steel with a thickness of 3mm, effectively separating flexible materials such as plastic bags and nylon from large solid particles such as stones and bricks in the mud-water mixture. The water storage tank 11 is constructed of 6mm carbon steel welded together and is entirely sealed and corrosion-resistant. The drain outlet 12 uses a 4-inch 304 stainless steel pipe to return the final filtered water back into the well.

[0033] The vacuum pump 1 and the mud-water separation tank 3 are connected by the connecting pipe 2. The vacuum pump 1 is started, and the vacuum pump 1 draws air into the mud-water separation tank 3 through the suction port 4 to create a vacuum. The mud-water mixture enters the mud-water separation tank 3 through the mud inlet 8. First, the plastic bags, nylon and other flexible materials and large solid particles such as stones and bricks in the mud-water mixture are separated by the grid 9. The remaining mud-water mixture is filtered again through the filter media 7 to separate small particles and suspended solids. The filtered water enters the water storage tank 11 through the water inlet 6 and is finally discharged through the drain outlet 12.
