Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1

[0029] Reference Figures 1-6This is the first embodiment of the present invention. This embodiment provides a vacuum suction system with automatic slag discharge function. The vacuum suction system with automatic slag discharge function includes a main component 100, including a vacuum tank 101. The vacuum tank 101 is provided with a water inlet pipe 102. A debris discharge pipe 103 is provided on one side of the water inlet pipe 102. A filter bucket 104 is fixed to one end of the debris discharge pipe 103. One end of the water inlet pipe 102 is inserted into the filter bucket 104. Both the water inlet pipe 102 and the debris discharge pipe 103 are provided with valves. When sewage is drawn from the water inlet pipe 102 into the vacuum tank 101, the valve on the debris discharge pipe 103 will close. The sewage flows into the filter bucket 104 through the water inlet pipe 102. Large particles of sediment will be filtered and left in the filter bucket 104, and then fall into the debris discharge pipe 103. The remaining sewage and small particles will enter the vacuum tank 101 through the filter holes on the filter bucket 104.

[0030] The cleaning component 200 is disposed inside the filter canister 104 and includes a cleaning element 201. The cleaning element 201 is disposed to clean the inner wall of the filter canister 104 to prevent the filter canister 104 from becoming clogged during use.

[0031] The cleaning component 201 includes a rotating shaft 2011 located inside the filter barrel 104. An impeller 2012 is fixed to the outside of the rotating shaft 2011. The impeller 2012 is used to drive the rotating shaft 2011 to rotate. A connecting rod 2013 is fixed on the rotating shaft 2011. A cleaning plate 2014 is fixed to one end of the connecting rod 2013. A cleaning brush 2015 is fixed to one end of the cleaning plate 2014. The other end of the cleaning brush 2015 is in contact with the inner wall of the filter barrel 104. The connecting rod 2013 causes the rotating shaft 2011 to rotate, which in turn drives the cleaning plate 2014 to rotate, thereby cleaning the inner wall of the filter barrel 104.

[0032] The blades of impeller 2012 are relatively small and have a large gap with the inner wall of filter barrel 104. Large particles will flow between the blades and between the blades and the inner wall of filter barrel 104 to the debris discharge pipe 103.

[0033] Because of the use of vacuum suction, the sewage flow rate is relatively fast. When the sewage flows into the filter bucket 104 through the inlet pipe 102, the sewage has a certain flow rate and a certain vertical drop with the blades of the impeller 2012, which impacts the blades of the impeller 2012. This force will give the impeller 2012 angular momentum, thus starting to rotate. The rotation of the impeller 2012 will drive the rotating shaft 2011 to rotate synchronously, which in turn drives the connecting rod 2013 to rotate. The cleaning plate 2014 and the cleaning brush 2015 will rotate, thereby cleaning the inner wall of the filter bucket 104 and preventing the filter bucket 104 from becoming clogged.

[0034] Example 2

[0035] Reference Figures 2-6This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, the cleaning assembly 200 also includes a fixing member 202 located on one side of the rotating shaft 2011, which provides stable support for the cleaning assembly 201. The fixing member 202 includes a fixing block 2021 connected to the bearing of the rotating shaft 2011. A fixing plate 2022 is fixed to one end of the fixing block 2021, and the other end of the fixing plate 2022 is fixed to the inner wall of the filter tank 104. The fixing plate 2022 and the fixing block 2021 provide support for the rotating shaft 2011, ensuring that the impeller 2012 will not shift its position when the sewage flows through the filter tank 104, but can rotate around the rotating shaft 2011.

[0037] Specifically, a backwash pipe 2016 is provided on one side of the impeller 2012. The backwash pipe 2016 is fixed on the debris discharge pipe 103, and the other end extends to the outside of the debris discharge pipe 103. A valve is also provided on the backwash pipe 2016. The end of the backwash pipe 2016 close to the impeller 2012 has its port coaxial with the center of the impeller 2012.

[0038] When water passes through the backwash pipe 2016, it flows axially towards the center of the impeller 2012, thereby driving the impeller 2012 to rotate again, which in turn drives the cleaning plate 2014 and the cleaning brush 2015 to rotate. At the same time, the backwash pipe 2016 is also provided with multiple through holes. When water flows through the backwash pipe 2016, some water will flow out from the through holes and spray onto the inner wall of the filter bucket 104. Together with the rotating cleaning brush 2015, it can clean the cleaning brush 2015 at the same time.

[0039] After the filter canister 104 has been used for a period of time, impurities will remain on the cleaning brush 2015 and the impeller 2012. Clean water is then introduced into the filter canister 104 through the backwash pipe 2016. The water flow impacts the center of the impeller 2012, causing the impeller 2012 to rotate, thereby completing the cleaning of the impeller 2012, the cleaning brush 2015, and the inner wall of the filter canister 104.

[0040] Specifically, the vacuum tank 101 is provided with a sludge discharge port 105 at the bottom, and the sludge discharge port 105 is also provided with a valve. When sewage enters the vacuum tank 101, the valve is closed. One end of the sludge discharge port 105 is connected to a screw conveyor 106, and the debris discharge pipe 103 is connected to the screw conveyor 106. The screw conveyor 106 is used to transport impurities to a designated location. This is existing technology, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0041] During the use of vacuum tank 101, slag needs to be discharged regularly. Large particles of impurities are collected in the slag discharge pipe 103 before entering vacuum tank 101. Sediments also exist at the bottom of vacuum tank 101. These sediments can be discharged from vacuum tank 101 through mud and sand discharge port 105.

[0042] When it is necessary to clean up impurities, open the valves corresponding to the debris discharge pipe 103 and the mud and sand discharge port 105. The debris will enter the material cylinder of the screw conveyor 106. Turn on the screw conveyor 106, and the impurities will be moved to the material cylinder outlet position by the push of the screw blades.

[0043] Specifically, a liquid level sensor 107 is installed at the top of the vacuum tank 101. The liquid level sensor 107 is used to monitor the real-time water level inside the vacuum tank 101. When the liquid level sensor 107 detects that the water level is at the highest position during sewage suction, it will send a signal to stop suction and then the drainage process can begin. During this process, the liquid level sensor 107 will also monitor the water level. When it detects that the water level is at the lowest position, it will send a signal to terminate the drainage operation.

[0044] Specifically, a vacuum suction port 101-1 is provided on the top of the vacuum tank 101, and a suction pump group 108 is provided on one side of the vacuum tank 101. The pipe of the suction pump group 108 is connected to the vacuum suction port 101-1, thereby connecting to the inside of the vacuum tank 101. The suction pump group 108 can adjust the pressure inside the vacuum tank 101 and can perform positive and negative pressure regulation. This is existing technology, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0045] When sewage needs to be moved into vacuum tank 101, all valves connected to vacuum tank 101 are closed. The suction pump unit 108 evacuates the inside of vacuum tank 101, and then opens the valve corresponding to inlet pipe 102. Using the pressure difference, sewage is quickly pumped into vacuum tank 101. When level sensor 107 detects that the water level is full, the electronic control system closes the valve corresponding to inlet pipe 102. Then, suction pump unit 108 switches to positive pressure state through reversing valve to add positive pressure to vacuum tank 101. Then, the valve corresponding to outlet pipe 1011 is opened to send sewage to the sewage treatment plant. When level sensor 107 detects that the water level is low, suction pump unit 108 stops working and closes the valve corresponding to outlet pipe 1011. This cycle repeats to achieve sewage collection and transfer.

[0046] The suction pump set 108 is used to achieve pressure drainage, thereby replacing the sewage pump and solving the problem of sewage pump blockage. At the same time, it is used in conjunction with the vacuum tank 101 to solve the problem of odor leakage from the sewage tank. The sewage pipe diameter is smaller than that of ordinary pipes, which facilitates pipe laying.

[0047] Example 3

[0048] Reference Figures 1-3 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0049] Specifically, a control mechanism 109 is provided on one side of the suction pump assembly 108. The control mechanism 109 can control the opening and closing of the valves on the suction pump assembly 108 and the vacuum tank 101. The real-time data monitored by the liquid level sensor 107 can be transmitted to the control mechanism 109, thereby precisely adjusting the opening and closing of each valve.

[0050] Specifically, a rotary rinsing mechanism 1010 is provided on the top of the vacuum tank 101. The rotary rinsing mechanism 1010 can rotate 360° to clean the inner wall of the vacuum tank 101. The rotary rinsing mechanism 1010 also has a self-lifting function. This is existing technology and will not be described in detail here. Moreover, those skilled in the art can clearly understand the working principle.

[0051] When using the vacuum tank 101, it needs to be cleaned regularly. First, open the rotary flushing mechanism 1010 to clean the inner wall of the vacuum tank 101. Then, open the valves corresponding to the debris discharge pipe 103 and the mud and sand discharge port 105, and start the screw conveyor 106. The sludge and particulate matter settled inside the tank enter the screw conveyor 106 through the debris discharge pipe 103 and the mud and sand discharge port 105, and are conveyed to the outlet position of the material cylinder by the screw conveyor 106.

[0052] The above process completes the automatic slag discharge of vacuum tank 101. Large-volume debris and bottom sediment mixed in the sewage are filtered and then transported to the designated slag discharge area by screw conveyor 106. The sewage can be discharged to the next stage pipeline for treatment through pipeline pressure, thereby reducing the workload of on-site operators and improving slag discharge efficiency.

[0053] Specifically, a water outlet pipe 1011 is fixed at the bottom of the vacuum tank 101. The water outlet pipe 1011 is used to discharge the liquid inside the vacuum tank 101 to the outside of the tank. A corresponding valve is also provided on the water outlet pipe 1011.

[0054] Specifically, a transfer vehicle 1012 is provided on one side of the screw conveyor 106. Under the action of the screw conveyor 106, the sludge and particulate matter settled inside the tank will be pushed to the discharge port of the conveyor. The transfer vehicle 1012 is placed below the discharge port to collect the debris and facilitate the transportation of the debris to the next processing stage.

[0055] During use, close all valves connected to the vacuum tank 101. The suction pump 108 evacuates the inside of the vacuum tank 101. Then, open the valve corresponding to the inlet pipe 102. Utilize the pressure difference to quickly pump sewage into the vacuum tank 101. During this process, the sewage flows into the filter bucket 104 through the inlet pipe 102. Large particles of sediment will be filtered and remain in the filter bucket 104, then fall into the debris discharge pipe 103. The remaining sewage and small particles will flow through the filter holes on the filter bucket 104 and enter the vacuum tank 101. When the sewage flows into the filter bucket 104 through the inlet pipe 102, it impacts the blades on the impeller 2012. This force will give the impeller 2012 angular momentum, causing it to start rotating. The rotation of the impeller 2012 will drive the rotating shaft 2011 to rotate synchronously, which in turn drives the connecting rod 2013 to rotate. The cleaning plate 2014 and the cleaning brush 2015 will rotate, thereby cleaning the inner wall of the filter bucket 104 and preventing the filter bucket 104 from becoming clogged.

[0056] When the level sensor 107 detects that the water level is full, the electronic control system closes the valve corresponding to the inlet pipe 102. Then, the suction pump group 108 switches to a positive pressure state through the reversing valve, adds positive pressure to the vacuum tank 101, and then opens the valve corresponding to the outlet pipe 1011 to pressurize the sewage to the sewage treatment plant's pipeline and deliver it to the sewage treatment plant. When the level sensor 107 detects that the water level is low, the suction pump group 108 stops working and closes the valve corresponding to the lower outlet pipe 1011. This cycle repeats to achieve the collection and transfer of sewage.

[0057] When the vacuum tank 101 needs to be cleaned periodically, first open the rotary flushing mechanism 1010 to clean the inner wall of the vacuum tank 101. Then, open the valves corresponding to the debris discharge pipe 103 and the sludge discharge port 105, and start the screw conveyor 106. The sludge and particulate matter settled inside the tank enter the screw conveyor 106 through the debris discharge pipe 103 and the sludge discharge port 105, and are conveyed to the outlet of the material cylinder by the screw conveyor 106. At the same time, they pass through the backwash pipe. In step 2016, clean water is injected into the filter canister 104. The water flows axially towards the center of the impeller 2012, thereby driving the impeller 2012 to rotate again. This, in turn, drives the cleaning plate 2014 and the cleaning brush 2015 to rotate. At the same time, multiple through holes are also provided on the backwash pipe 2016. When water flows through the backwash pipe 2016, some water will flow out from the through holes and spray onto the inner wall of the filter canister 104. Together with the rotating cleaning brush 2015, the cleaning brush 2015 can be cleaned simultaneously.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
