Description

Technical Field

[0001] This invention relates to the field of pipeline cleaning technology, specifically to an independent module for flushing pipe fittings and a flushing method. Background Technology

[0002] During diesel engine commissioning, frequent model changes necessitate the frequent construction or modification of auxiliary piping at the test bench. Maintaining consistent cleanliness within the piping during construction is challenging, making internal piping cleaning an indispensable part of the production process. Furthermore, with the increasing adoption of lean manufacturing principles, the industry requires that diesel engine components undergo cleanliness verification before assembly, thereby shortening the piping flushing time after the diesel engine is installed and reducing the time spent occupying the test bench.

[0003] Currently, pipeline cleaning is generally carried out by flushing and cleanliness testing on the test bench after the diesel engine is in place. This cleaning mode is not only inefficient and consumes a lot of test bench time, but also lacks a mature and standardized pipeline cleaning process, resulting in limited cleaning effectiveness and further restricting pipeline flushing efficiency, which is not conducive to improving test bench capacity. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an independent pipe flushing module and flushing method. Through the independent module design, pipe flushing can be performed outside the test bench, which is convenient to operate, reduces the occupation of the test bench, and improves production efficiency.

[0005] The technical objective of this invention is achieved through the following technical solution: A separate module for flushing pipe fittings, comprising: A media storage tank is used to store flushing media for pipe fittings, and has a media outlet and a media inlet; The pump body has a pump body inlet and a pump body outlet. The pump body inlet is connected to the medium outlet through a pipe, and the pump body outlet is connected to a first pipe fitting for connection with the pipe fitting to be flushed through a pipe. A filter module is installed on the pipeline between the pump inlet and the medium outlet to filter the flushing medium flowing out of the medium outlet; The flushing medium return pipeline has a second pipe connector at one end for connecting to the pipe fitting to be flushed, and a medium inlet at the other end. A first return pipe and a second return pipe are connected in parallel between the two ends of the flushing medium return pipeline. A flushing medium inspection module is connected to the first return pipe, and the flushing medium inspection module is equipped with a removable filter screen. Valves for controlling the flow of flushing medium are respectively installed at the front end of the first return pipeline and on the second return pipeline. The housing integrates the media storage tank, pump body, and filter module inside the housing, while the flushing media return pipeline is located outside the housing.

[0006] Furthermore, the filtration module includes a screen filtration module and an adsorption filtration module, with the screen filtration module positioned at the front end of the adsorption filtration module.

[0007] Furthermore, the filter module includes at least two stages of filtration system, with the filtration accuracy increasing along the flow path of the rinsing medium.

[0008] Furthermore, the adsorption filter module is a magnetic filter.

[0009] Furthermore, the flushing medium return line uses a flexible hose.

[0010] Furthermore, the bottom of the box is equipped with wheels for movement.

[0011] Furthermore, the module also includes a vibration module for mounting on the pipe fitting to be flushed.

[0012] Furthermore, the first and second pipe fittings are detachable.

[0013] The present invention also provides a method for flushing pipe fittings using an independent pipe fitting flushing module, the method comprising: Step 1: Install the first pipe connector and the second pipe connector at both ends of the pipe fitting to be flushed; Step 2: Close the valve on the first return line and open the valve on the second return line; Start the pump body, and the flushing medium in the medium storage tank is drawn out from the medium outlet and delivered to the pipe to be flushed. The flushing medium is then returned to the medium storage tank through the second return pipeline. The cyclic flushing continues for 24 hours. Step 3: After opening the valve on the first return line, close the valve on the second return line, circulate and flush for 2 hours, then turn off the pump. Step 4: Open the flushing medium inspection module and check the residual impurities in the filter screen of the flushing medium inspection module: If there are residual impurities, restart the pump and execute step 3; if there are no residues, the flushing is complete.

[0014] Furthermore, the method also includes installing a vibration module on the pipe to be flushed before step 2; the vibration module remains vibrating during the flushing process.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The independent pipe flushing module of the present invention enables the cyclic flushing of pipes outside the test bench, reducing the time occupied by the test bench and improving production efficiency; the flushing medium of the cyclic flushing can be recycled, reducing costs and improving material utilization.

[0016] 2. The independent pipe flushing module of the present invention filters out impurities from the flushing medium through different filtration methods, ensuring that there are no impurities in the flushing medium when flushing pipes, thus guaranteeing the effect of circulating flushing.

[0017] 3. The independent pipe flushing module of the present invention is designed with integration and can be moved according to actual working conditions, which is more convenient.

[0018] 4. The independent pipe flushing module of the present invention, through the setting of the vibration module, can vibrate the pipe to be flushed while flushing, thereby improving the flushing effect inside the pipe and reducing the problems of impurities adhering to the inner wall of the pipe and being difficult to flush, as well as the poor flushing effect caused by the dead corners of the flushing.

[0024] The technical solution of the present invention will be further described below with reference to specific embodiments: A separate module for pipe flushing, such as Figure 1 As shown, it includes: The media storage tank 1 is used to store the flushing medium for the pipe fittings and has a media outlet and a media inlet; for example, the flushing medium may be diesel fuel. Pump body 2 has a pump body inlet and a pump body outlet. The pump body inlet is connected to the medium outlet through a pipe, and the pump body outlet is connected to a first pipe joint 3 for connection with the pipe fitting 12 to be flushed through a pipe. A filter module is installed on the pipeline between the pump inlet and the medium outlet to filter the flushing medium flowing out of the medium outlet; The flushing medium return pipeline 4 has a second pipe connector 5 at one end for connecting to the pipe fitting to be flushed, and a medium inlet at the other end. A first return pipe 6 and a second return pipe 7 are connected in parallel between the two ends of the flushing medium return pipeline 4. A flushing medium inspection module 8 is connected to the first return pipe 6, and the flushing medium inspection module 8 is equipped with a detachable filter screen. A valve body 9 for controlling the flow of flushing medium is provided at the front end of the first return pipeline 6 and the second return pipeline 7 is provided with a valve body 10 for controlling the flow of flushing medium. The valve bodies 9 and 10 are ball valves. The housing 13 integrates the media storage tank 1, the pump body 2 and the filter module inside the housing 13, while the flushing media return pipeline 4 is located outside the housing 13.

[0025] In one implementation process, the flushing medium inspection module 8, as shown in... Figure 3 and Figure 4 As shown, the flushing medium inspection module 8 includes a cylinder 81 and an openable cover 82 mounted on the cylinder. A flange is provided at the upper end of the cylinder 81, and the cover 82 can be fixed to the flange of the cylinder 81 with screws. A first return pipe 6 is connected to the upper and lower ends of the cylinder 81. The first return pipe 6 connects to the upper end of the cylinder 81 for the flushing medium to flow in, and connects to the lower end of the cylinder for the flushing medium to flow out. A pocket-shaped filter screen 83 is provided inside the cylinder. When the flushing medium flows in through the upper end of the cylinder 81, it is filtered by the filter screen and flows out through the lower end of the cylinder 81. If there are solid particulate impurities in the flushing medium as it passes through the filter screen 83, they will be intercepted by the filter screen 83. The presence of solid particulate impurities in the filter screen 83 is checked to determine whether the flushing of the pipe fitting 12 is complete. It should be noted that the filtration accuracy of the filter screen 83 of the flushing medium inspection module 8 is not lower than the highest filtration accuracy of the filter module. More specifically, a raised ring 84 is provided on the side wall of the cylinder 81 below the position where the flushing medium flows in, and a rigid ring 85 is provided at the upper opening of the filter screen. The rigid ring 85 of the filter screen 83 is placed on the raised ring 84 to realize the installation of the filter screen.

[0026] Specifically, the filtration module includes a screen filtration module and an adsorption filtration module. The screen filtration module is located at the front end of the adsorption filtration module. First, the screen filtration module filters the impurities in the rinsing medium, and then the adsorption filtration module performs adsorption filtration on the impurities in the rinsing medium.

[0027] Preferably, the filter module includes at least two stages of filtration, and the filtration accuracy increases along the flow path of the rinsing medium. In one implementation, such as Figure 1As shown, the filter module includes a first filter 14 as a primary filter and a second filter 15 as a secondary filter. The primary filter achieves preliminary filtration, and the secondary filter achieves further fine filtration. The adsorption filter module uses a magnetic filter 16.

[0028] The first filter 14 and the second filter 15 filter impurity particles through filter screens of different mesh sizes, and the magnetic filter 16 adsorbs iron filings and other particles in the rinsing medium through a magnetic rod; the impurities and iron filings in the rinsing medium mainly come from the inside of the pipe fittings to be rinsed.

[0029] In one implementation process, to enhance the flushing effect, the independent flushing module for the pipe fitting is also equipped with a vibration module 11, such as... Figure 2 As shown, the vibration module 11 is not connected to the housing 13 and is an independent device. The vibration module 11, like a vibration pump, is installed on the outer wall of the pipe fitting 12 to be rinsed to provide vibration, thereby increasing the rinsing effect.

[0030] Preferably, the flushing medium return pipeline 4 is made of a flexible hose, which facilitates adjustment of position and angle and storage. In addition, when the vibration module 11 is installed, it can also reduce the impact on the housing.

[0031] Preferably, the bottom of the housing 13 is also provided with wheels for movement, making it convenient to move to different areas for use.

[0032] Preferably, in one implementation process, the first pipe joint 3 and the second pipe joint 5 are detachable. The first pipe joint 3 and the second pipe joint 5 are such as flange joints, threaded joints, etc., and can be replaced according to the specifications of the flushing pipe fitting 12 by means of detachable configuration.

[0033] This embodiment also provides a method for flushing pipe fittings using a separate pipe fitting flushing module, the method comprising: Step 1: Install the first pipe connector 3 and the second pipe connector 5 at both ends of the pipe fitting 12 to be flushed, as follows: Figure 2 As shown; preferably, a vibration module 11 can also be installed on the outer wall of the pipe fitting 12 to be flushed, and the vibration module 11 can be fixed to the outer wall of the pipe fitting 12 to be flushed by clamps or the like. Step 2: Close valve 9 on the first return line 6 and open valve 10 on the second return line 7. At this time, there are likely impurities in the flushing medium after flushing. Therefore, the flushing medium will not be checked through the flushing medium inspection module 8 of the first return line 6 for the time being. Start pump body 2. The flushing medium in media storage tank 1 is drawn out from the media outlet through pump body 2 and then passes through first filter 14, second filter 15 and magnetic filter 16 in sequence before being delivered to the pipe fitting 12 to be flushed. The flushing medium output by pump body 2 is pressurized. After flushing, the flushing medium flows back to media storage tank 1 through second return pipeline 7 and finally along flushing medium return pipeline 4. The cycle flushing continues for 24 hours. Step 3: After opening valve 9 on the first return line 6, close valve 10 on the second return line 7, then circulate and flush for 2 hours, and then turn off pump 2. Step 4: Open the flushing medium inspection module 8 and check the residue of impurities in the filter screen of the flushing medium inspection module 8. If impurities are present, restart the pump body 2 and execute step 3; if no residue is present, the flushing is complete. When checking the filter screen of the flushing medium inspection module 8, it can be observed visually, or it can be adsorbed using a magnetic rod or similar device.

[0034] This embodiment is merely a further explanation of the present invention and is not intended to limit the present invention. Those skilled in the art can make non-inventive modifications to this embodiment as needed after reading this specification, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
