Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cleaning, in particular to a perfusion lumen pulse cleaning device. Background Art

[0002] Existing water supply pipes are often made of steel. Due to long-term contact with water, the inner wall of the pipe is more prone to rust than the outer wall of the pipe. If the rusted inner wall of the pipe is not cleaned, the rust rate will be faster. Traditional pipe cleaning methods usually use high-pressure water guns, mechanical brushes or chemical cleaning agents to clean the inner wall of the pipe. Although these methods can remove dirt and impurities in the pipe to a certain extent, they have shortcomings such as incomplete cleaning and low efficiency.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Example 1

[0025] See Figures 1 to 5 As shown, a perfusion lumen pulse cleaning device is characterized in that it includes a water tank 1, a pressure tank 2 and a cleaning mechanism 3, wherein the front end of the water tank 1 is provided with a No. 1 solenoid valve 11, the front end of the pressure tank 2 is provided with a No. 2 solenoid valve 21, and the top of the pressure tank 2 is provided with an electronic control system 4; the cleaning mechanism 3 includes a water storage pipe 31 flange-connected to the No. 1 solenoid valve 11, the middle part of the water storage pipe 31 is flange-connected to the No. 2 solenoid valve 21, the other end of the water storage pipe 31 is flange-connected to a spiral tube 32, the middle part of the spiral tube 32 is provided with a valve seat 33, a support seat 34 is provided below the valve seat 33, a valve core 35 is rotatably installed inside the valve seat 33, the valve core 35 is fixedly connected to the output end of the motor 36, the motor 36 is fixedly installed on the support seat 34, the other side of the spiral tube 32 is flange-connected to a pipeline, and the other side of the pipeline is provided with a filter cartridge 37. The water tank 1 is used to load the cleaning liquid of the mixed disinfectant for flushing the pipeline, and the pressure tank 2 is responsible for providing pulse pressure to spray the water out. The switch of the solenoid valve is controlled by the electronic control system 4 to control the frequency of water flushing. The spiral tube 32 makes the water flow rotate, thereby increasing the pressure on the pipe wall, thereby enhancing the cleaning ability of the pipe wall.

[0026] The inner wall of the spiral tube 32 is provided with a plurality of guide plates 321, which are tilted between 30° and 45° relative to the axis of the spiral tube 32. After the water flows through the guide plates 321, it rotates and generates centrifugal force, thereby increasing the pressure on the pipe and improving the efficiency of pipe cleaning. The guide plates 321 are tilted between 30° and 45° relative to the axis of the spiral tube 32, which can maximize the rotation of the water flow while reducing water resistance.

[0027] A sealing hole 331 is formed through one side of the valve seat 33. A rotating chamber 332 is formed in the center of the valve seat 33. A valve core 35 is rotatably mounted within the rotating chamber 332. A funnel 333 is eccentrically disposed on the top of the valve seat 33. The bottom of the funnel 333 is positioned on one side of the sealing hole 331. The funnel 333 is filled with corundum. A rotating hole is provided at the bottom of the valve seat 33. The corundum contained in the funnel 333 allows the flushing water to be mixed with the corundum, thereby improving rust removal efficiency.

[0028] The valve core 35 is adapted to fit the valve seat 33. A mixing hole 351 is formed through the center of the valve core 35, and a metering hole 352 is formed eccentrically on the upper portion of the valve core 35. The metering hole 352 is connected to the mixing hole 351, and the center of the metering hole 352 and the center of the bottom of the funnel 333 are equidistant from the center of the valve core 35 on a projected plane. The metering hole 352 and the bottom of the funnel 333 overlap in planar projection, and the bottom of the funnel 333 is located to one side of the sealing hole 331. This ensures that, relative to the valve seat 33, when the valve core 35 is open, water flows through, but corundum cannot pass through the funnel 333 into the mixing hole 351. When the valve core 35 is closed, water cannot flow through, but corundum can pass through the funnel 333 into the mixing hole 351.

[0029] The volume ratio of the mixing hole 351 to the water storage pipe 31 is 1:20. The ratio of corundum to water must be maintained within a certain range to achieve the best flushing effect of the water flow, otherwise it will affect the flushing effect. By setting a quantitative flushing, the flushing efficiency is improved.

[0030] A filter screen 371 is provided inside the filter cartridge 37. The pore size of the filter screen 371 is smaller than the diameter of the corundum. The filter screen 371 is used to recycle the corundum, thereby reducing the cost of pipeline cleaning.

[0031] Example 2

[0032] The electric control system 4 of the present utility model adopts an external power supply;

[0033] The pressure tank 2 of the present invention is used to generate compressed air and has the same structure as the existing air compressor and compressed air storage;

[0034] The water tank 1 of the present invention is provided with a scale line on the side so as to observe the liquid level and replenish the cleaning liquid in time;

[0035] A cleaning agent is added to the water tank 1 of the utility model;

[0036] The first solenoid valve 11, the second solenoid valve 21 and the motor 36 of the present invention are all electrically connected to the electronic control system 4;

[0037] The pipeline to be cleaned in the present invention should not be too long so that the cleaning liquid can flow out;

[0038] The diamond abrasive of the present invention has a hollow structure and is relatively light in weight;

[0039] The sealing gap between the valve core 35 and the valve seat 33 of the present invention is smaller than the diameter of the diamond.

[0040] Example 3

[0041] Working principle: Before cleaning the pipe, the user first fills the water tank 1 with water and adds detergent to the water, then connects the spiral tube 32 to the flange of the pipe to be cleaned, and places the filter cartridge 37 at the end of the pipe to be cleaned; when cleaning the pipe, the user controls the No. 1 solenoid valve 11, the No. 2 solenoid valve 21 and the motor 36 through the electronic control system 4. First, the motor 36 controls the valve core 35 to rotate, thereby sealing one end of the water storage pipe 31. When the valve core 35 is closed, the bottom of the funnel 333 coincides with the metering hole 352, so that the corundum in the funnel 333 enters the mixing hole 351 through the metering hole 352;

[0042] Under the control of the electronic control system 4, the second solenoid valve 21 is opened, so that the cleaning liquid in the water tank 1 enters the water storage pipe 31, and compressed gas is generated in the pressure tank 2. After the water storage pipe 31 is filled with water, the electronic control system 4 controls the second solenoid valve 21 to close, and then controls the first solenoid valve 11 and the motor 36 to rotate simultaneously, so that the first solenoid valve 11 and the valve core 35 are opened at the same time, so that the compressed gas in the pressure tank 2 bursts out, thereby promoting the movement of the cleaning liquid in the water storage pipe 31. When the cleaning liquid passes through the spiral tube 32, the cleaning liquid rotates through the drainage pipe. At the same time, when the cleaning liquid passes through the valve core 35, the cleaning liquid moves with the corundum, thereby causing the corundum to rotate and move forward on the inner wall of the pipe. The rotation of the corundum generates centrifugal force, thereby rubbing against the inner wall of the pipe, thereby removing the rust on the inner wall of the pipe.

[0043] After the cleaning liquid for cleaning the pipe is sprayed out from the pipe outlet, the cleaning liquid enters the filter cartridge 37 and is filtered by the filter screen 371. The cleaning liquid flows out and the diamond abrasive is retained in the filter cartridge 37. When the user observes that the flowing cleaning liquid changes from red to clear, it means that the pipe has been cleaned.

[0044] In addition, if the motor 36 is rotated in a different direction, when the motor rotates to one side, the corundum enters the mixing hole 351 through the metering hole 352, so that the cleaning liquid contains corundum; if the motor 36 rotates to the other side, the valve core 35 seals the valve seat 33 while also sealing the metering hole 352, so that after the valve core 35 is opened, the cleaning liquid does not contain corundum, thereby improving the comprehensiveness of the device.
