[0019] As shown in Figures 1 to 8 A pipeline anti-blocking device of a non-negative pressure water supply equipment, comprising a treatment tank 2, the input and output ends of the treatment tank 2 are connected with a water supply pipeline 1, and a tank cover body 3 is fixedly installed at the top end of the treatment tank 2; as shown in Figure 3 and Figure 4As shown, specifically, the treatment tank 2 includes a tank body 201, the surface of the tank body 201 is provided with a water inlet 202 and a discharge port 203, the ends of the water inlet 202 and the discharge port 203 are connected with the water supply pipeline 1, the inner wall of the tank body 201 is fixedly installed with a blowdown baffle 204, the surface of the tank body 201 is provided with a blowdown port 205, and the blowdown port 205 is provided with a blowdown valve 206.

[0020] More specifically, the surface of the tank body 201 is also provided with a blowdown port 205, and the blowdown port 205 is provided with a blowdown valve 206 for controlling the opening and closing of the blowdown operation. When blowdown is needed, the blowdown valve 206 is opened and impurities are discharged from the treatment tank 2 through the blowdown port 205 to realize the cleaning of impurities in the pipeline and ensure the normal operation of the water supply equipment.

[0021] As shown in the figure, Figure 6 Specifically, the bottom end of the filter screen body 5 is attached to the top surface of the blowdown baffle 204, and the top surface of the blowdown baffle 204 is provided with two sets of sealing limiting rings 51 for sealing the gap between the filter screen body 5 and the blowdown baffle 204.

[0022] More specifically, the two sets of sealing limiting rings 51 on the top surface of the blowdown baffle 204 seal the gap between the filter screen body 5 and the blowdown baffle 204 to prevent unfiltered water flow from flowing out directly through the gap, thereby ensuring the reliability of the filtering effect.

[0023] As shown in the figure, Figure 3 The water inlet 202 is located above the filter screen body 5 installed inside the tank body 201, and the water inlet 202 is located below the top end of the filter screen body 5.

[0024] More specifically, after the water flow enters the treatment tank 2, it is first filtered by the filter screen body 5 to intercept impurities, and then discharged through the discharge port 203.

[0025] The input end and the output end of the treatment tank 2 and the top surface of the tank cover 3 are provided with a differential pressure detection module 4 for detecting the pressure difference of the water flow; as Figures 1 to 3 Specifically, the differential pressure detection module 4 includes water pressure detection probes 401 respectively inserted into the water inlet 202 and the discharge port 203, the top surface of the tank cover 3 is fixedly installed with a controller 403, the connection end of the controller 403 is connected with a wire 402, and the controller 403 is connected with the water pressure detection probes 401 through the wire 402.

[0026] More specifically, the water pressure detection probes 401 transmit the detected pressure signals to the controller 403, and the controller 403 analyzes and processes the signals according to the set pressure difference threshold value. When the pressure difference reaches the set value, the controller 403 issues an instruction to start the corresponding blowdown and cleaning operation.

[0027] The inner wall of the treatment tank 2 is fixedly provided with a filter screen body 5 for filtering water resources, and a sewage discharge assembly 6 is arranged at the bottom end of the treatment tank 2 and in the interior thereof. Figures 1 to 7 As shown in the figure, specifically, the sewage discharge assembly 6 comprises an end cover 601 fixedly arranged at the bottom end of the tank body 201, the bottom surface of the end cover 601 is fixedly provided with an electric motor 602, the output end of the electric motor 602 is fixedly connected with a rotating shaft 603, and the surface of the rotating shaft 603 is fixedly sleeved with a spiral auger 604, which is arranged in the interior of the tank body 201 and the sewage discharge partition plate 204.

[0028] More specifically, when sewage needs to be discharged, the electric motor 602 is started to drive the rotating shaft 603 to rotate, thereby driving the spiral auger 604 to rotate, and the rotation of the spiral auger 604 can stir and transport the impurities accumulated at the bottom of the treatment tank 2 to the sewage discharge port 205, and then discharge the treatment tank 2 through the sewage discharge port 205, so as to effectively clean the impurities and ensure the smoothness of the pipeline. At the same time, the compact structure can well cooperate with other components in the interior of the treatment tank 2, and improve the operation efficiency and reliability of the whole device.

[0029] The top end of the sewage discharge assembly 6 is fixedly connected with a cleaning assembly 7, which is driven to rotate to filter the impurities on the inner wall of the filter screen body 5 when the sewage is discharged through the sewage discharge assembly 6. Figures 2 to 7 As shown in the figure, specifically, the cleaning assembly 7 comprises a U-shaped frame 701 inserted at the top end of the rotating shaft 603, a first bolt 702 is threadedly inserted between the U-shaped frame 701 and the rotating shaft 603, and the surface of the first bolt 702 is fixedly connected with a cleaning brush 704 through a second bolt 703.

[0030] More specifically, when the sewage discharge assembly 6 works, the rotating shaft 603 drives the U-shaped frame 701 to rotate, so that the cleaning brush 704 rotates to brush and clean the impurities attached to the filter screen body 5, thereby preventing the impurities from being accumulated to cause blockage, improving the filtering effect and service life of the filter screen body 5, and ensuring the normal operation of the whole pipeline anti-blocking device.

[0031] In some actual applications, when the pressure difference detection module 4 detects that the pressure difference reaches the set value, the sewage discharge assembly 6 and the cleaning assembly 7 are used to clean and discharge the impurities through the control system.

[0032] More specifically, the sewage discharge assembly 6 discharges the impurities accumulated at the bottom of the treatment tank 2 through the mechanical structure or power device in the interior thereof, and at the same time, the cleaning assembly 7 rotates under the driving of the sewage discharge assembly 6 to scrape or brush the inner wall of the filter screen body 5, thereby cleaning the impurities attached to the filter screen body 5 to restore the filtering performance, so as to effectively clean and discharge the impurities and ensure that the pipeline anti-blocking device can work continuously and stably.

[0033] In some practical applications, the cleaning brush 704 is in close contact with the inner wall of the filter screen body 5, and the bristle part of the cleaning brush 704 is made of a corrosion-resistant and high-strength material.

[0034] More specifically, the bristle part of the cleaning brush 704 is made of a corrosion-resistant and high-strength material, which can maintain good performance in complex water quality environment, is not easy to be damaged, can effectively clean the filter screen body 5 for a long time, prevent impurities from adhering to cause blockage, improve the operation efficiency and stability of the whole pipeline anti-blocking device, and reduce the maintenance cost.

[0035] In summary: the input and output ends of the treatment tank 2 are connected with the water supply pipeline 1 respectively, which ensures that the water flow can enter and exit smoothly, and the filter screen body 5 inside the treatment tank 2 filters the water resources flowing through and intercepts impurities. The differential pressure detection module 4 is arranged at the input and output ends of the treatment tank 2 and the tank, which is used for detecting the pressure difference of the water flow. When the pressure difference reaches a certain value, it indicates that there may be a blockage in the pipeline, and the pollution discharge work is started. When discharging pollution, the pollution discharge assembly 6 works while driving the cleaning assembly 7 to rotate, and the impurities on the inner wall of the filter screen body 5 are cleaned to prevent impurities from accumulating to cause blockage and ensure the smoothness of the pipeline.

[0036] The above shows and describes the basic principles, main features and advantages of the present application. It should be understood by those skilled in the art that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only the principles of the present application.
