Description

Technical Field

[0001] The utility model relates to a cleaning tool, in particular to a tool for cleaning copper pipes. Background Art

[0002] An air compressor uses a cooler to cool its circulating oil, maintaining it within a normal temperature range and ensuring continuous, efficient operation. However, over time, the cooling water used in the compressor cooler deteriorates due to the long-term circulation of tap water. Furthermore, the cooling tower itself acts as a dust collector, collecting dust from the air into the water, which in turn causes the water to harden and form scale. Due to the heat exchange between the inner and outer walls of the copper tubes, a large amount of scale forms on the inner walls. Over time, this buildup thickens, narrowing the water path and causing poor heat transfer. This leads to temperature deviations within each stage of the compressor, affecting the performance match between stages, reducing compressor efficiency, decreasing gas production, increasing energy consumption, and degrading overall unit performance. Therefore, regular cleaning of the copper tubes within the cooler is necessary to ensure optimal operating conditions for the air compressor.

[0003] At present, for the cooling water flowing in the copper tube of the air compressor cooler, a large amount of scale is generated inside the tube wall during long-term use. The scale is very firmly formed on the tube wall. There is no suitable cleaning tool. If ordinary cleaning methods such as high-pressure water gun flushing are used, the scale on the tube wall cannot be cleaned at all. The cleaning effect of this method is not obvious, which affects the early commissioning of the equipment and the subsequent use effect. Utility Model Content

[0004] The purpose of the utility model is to provide a tool for cleaning copper tubes to solve the technical problems in the prior art. The tool can efficiently clean scale on the inner wall of the cooler copper tube and effectively improve the cleaning efficiency and cleaning effect.

[0018] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0019] The embodiment of the present utility model: Figure 1-Figure 3 As shown, a tool for cleaning copper pipes includes a first elbow joint 1, a compressed air pipe 2, a second elbow joint 3, a ball valve 4, a ferrule elbow 5 and a cleaning pipe 6. One end of the compressed air pipe 2 is connected to the water source through the first elbow joint 1, and the other end of the compressed air pipe 2 is connected to one end of the ball valve 4 through the second elbow joint 3. The other end of the ball valve 4 is connected to one end of the cleaning pipe 6 through the ferrule elbow 5, and a descaling structure is formed at the other end of the cleaning pipe 6.

[0020] The water source can be tap water, a water tank, or high-pressure water. Whether it is tap water or other high-pressure water, the technical solution of this application can be implemented, and the valve of the water source is not the improvement point of this technical solution. Specifically, when it comes to the selection of the valve, technical personnel in this field can implement the technical solution of this application by making a selection according to actual needs.

[0021] After opening ball valve 4, water passes through first elbow 1, compressed air pipe 2, second elbow 3, ball valve 4, and ferrule elbow 5, and finally sprays out from the end of cleaning pipe 6, achieving a flushing function. The descaling structure at the end of cleaning pipe 6 can easily remove scale from the inner wall of the cooler's copper tube.

[0022] The material of the ferrule elbow 5 is stainless steel or other materials with greater hardness, so as to provide sufficient support for the rotation of the cleaning tube 6 during the cleaning process.

[0023] In a specific embodiment, one end of the first elbow joint 1 and the second elbow joint 3 are both formed with external threads, and the other ends of the first elbow joint 1 and the second elbow joint 3 are both formed with internal threads.

[0024] In this embodiment, the external threaded end of the first elbow joint 1 is connected to the water source, the internal threaded end of the first elbow joint 1 is connected to the compressed air pipe 2, the internal threaded end of the second elbow joint 3 is connected to the compressed air pipe 2, and the external threaded end of the second elbow joint 3 is connected to the ball valve 4. Of course, according to actual needs, an elbow joint with internal threads at both ends or both ends can also be selected.

[0025] Furthermore, the material of the cleaning tube 6 is usually stainless steel, but it can also be other materials with higher hardness. The descaling structure is composed of multiple first spikes 7 and multiple second spikes 8. The first spikes 7 and the second spikes 8 are alternately arranged along the circumferential direction on the end face of the cleaning tube 6.

[0026] The number of the first spike portion 7 and the second spike portion 8 is selected as needed, but the total number is usually more than three, but not too many, otherwise the hardness of the spike portion will be affected. For example, in this embodiment, three first spike portions 7 and three second spike portions 8 are preferably provided.

[0027] The three first spikes 7 extend axially along the cleaning tube 6, while the three second spikes 8 are inclined outward. The maximum circumscribed diameter of the ends of the three second spikes 8 is larger than the outer diameter of the cleaning tube 6. With this structure, when the cleaning tube 6 is rotated during cleaning, the three second spikes 8 scrape against the inner wall of the copper tube to be cleaned, removing scale. Simultaneously, these second spikes 8 are twisted 5-10 degrees to ensure that their sides also scrape against the inner wall of the copper tube, improving scale removal efficiency.

[0028] The axial length of the first spike portion 7 is smaller than the axial length of the second spike portion 8. The purpose of this design is that when high-pressure water passes through the cleaning pipe 6, turbulence is generated outside the water flow beam, thereby improving the removal of adhered scale residue to the greatest extent.

[0029] The inner surface of the first spike portion 7 is provided with a longitudinal guide groove 10. The water flow rate through the guide groove 10 changes, also in order to improve the cleaning of scale in the copper pipe.

[0030] Further, a compressed air connector 9 is provided on the side wall of the compressed air pipe 2, and the compressed air connector 9 is arranged obliquely. Compressed air can be introduced through the compressed air pipe 2, which can increase the speed of the water flow and make the cleaning effect better.

[0031] The working principle of the utility model is as follows: when working, first open the valve of the water source, then open the valve of the ball valve 4, and insert one end of the cleaning pipe 6 with the first spike portion 7 and the second spike portion 8 into the copper pipe until it can no longer be inserted. Adjust the opening of the ball valve 4 according to the size of the return water, and then start flushing while turning. The second spike portion 8 scrapes the inner wall of the copper pipe to make the scale fall off and flush it away until all the copper pipes are unblocked. Then fully open the ball valve 4, flush with water for 30 seconds, change a copper pipe, and dredge them one by one according to the above steps until all are unblocked.

[0032] When the water pressure of the water source is low and the water flow rate cannot meet the usage requirements, compressed air is introduced into the compressed air pipe 2 to increase the water flow rate.

[0033] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
