Description

Technical Field

[0001] The utility model relates to the technical field of heat supply network filtration and cleaning, in particular to a filtration and cleaning device for a heat supply network. Background Technique

[0002] A heat supply network refers to a pipeline system that transports and distributes heat supply media (hot water or steam) from a heat source to heat users. It is like a huge "vascular network" that transports heat energy from the heat supply source to various buildings to meet the heating, hot water supply and other needs of residents and industrial users. During the operation of the heat supply network, impurities, rust, scale, etc. may enter the pipeline. If not filtered, these substances will gradually accumulate, block the pipeline, affect the flow of hot water or steam, and reduce the heating efficiency.

[0003] In the Chinese utility model patent, such as the utility model of CN219423858U, a heat supply network filtration and cleaning device is disclosed, belonging to the technical field related to heat supply network filtration. This heat supply network filtration and cleaning device can enable a cleaning brush to clean a circular filter net, so that the user does not need to manually clean the circular filter net, which is convenient to use. At the same time, the user can pull out the plug, and then it is convenient to discharge the sewage and sundries after cleaning, with diverse functions;

[0004] When the above technology is used, only the surface of the filter net is cleaned by the cleaning brush. However, after the cleaning brush is used for a long time, it will be worn, resulting in the cleaning brush being unable to contact the surface of the filter net, thus unable to produce a cleaning effect. At the same time, the cleaning brush may not be able to reach the fine gaps and grooves of the filter plate, resulting in scale residues in these parts. Content of the Utility Model

[0010] Preferably, a plurality of spring telescopic rods are installed on the bottom surface of each of the rotating rods, and the other ends of the plurality of spring telescopic rods are fixedly connected to the top surface of the cleaning plate at a corresponding position.

[0011] Preferably, a baffle is fixedly installed at one end of each of the limiting rods, and the diameter length of each baffle is greater than the diameter length of the limiting rod.

Detailed Description of the Preferred Embodiment

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Refer to Figures 1-4, A filtering and cleaning device for a heat supply pipe network, including a bracket 1. A driving box 2 is fixedly installed on the top surface of the bracket 1, and a filtering box 3 is fixedly installed on the top surface of the driving box 2. A plurality of filtering cylinders 7 are respectively arranged in the filtering box 3, and each filtering cylinder 7 is communicated with each other. Every two adjacent filtering cylinders 7 are communicated through a communicating pipe 6. A heating device 4 is communicated with the outside of one of the filtering cylinders 7, and a drain pipe 5 is communicated with the filtering cylinder 7 corresponding in position. A plurality of filtering discs 8 are fixedly installed in each filtering cylinder 7;

[0027] It should be noted that the heating device 4 can heat the water in the pipeline, and this technology has been described in detail in the comparative document, so it will not be elaborated here. At the same time, the scale and impurities in the pipeline are filtered through the filtering discs 8. There are a plurality of motors in the driving box 2, and the output shaft of each motor is connected to the corresponding rotating shaft 9, and the rotating shaft 9 provides the driving source;

[0028] A plurality of rotating rods 11 are rotatably connected in each filtering cylinder 7. A cleaning plate 22 is elastically connected to the bottom surface of each rotating rod 11. A plurality of spring telescopic rods 21 are installed on the bottom surface of each rotating rod 11, and the other ends of the plurality of spring telescopic rods 21 are fixedly connected to the top surface of the corresponding cleaning plate 22. Each cleaning plate 22 abuts against the top surface of the corresponding filtering disc 8. The length of each cleaning plate 22 is the same as the radius length of the filtering disc 8, and one end of each rotating rod 11 is fixedly installed on the outside of the corresponding rotating shaft 9;

[0029] It should be noted that through the plurality of spring telescopic rods 21, each cleaning plate 22 can always abut against the top surface of the filtering disc 8. Therefore, when the cleaning plate 22 is worn, the spring telescopic rods 21 can continue to make the cleaning plate 22 abut against the top surface of the filtering disc 8, thereby prolonging the service life of the cleaning plate 22;

[0030] A plurality of rotating shafts 9 and a plurality of reciprocating lead screws 10 are rotatably connected in each filtering cylinder 7, and each rotating shaft 9 and the reciprocating lead screw 10 are connected in sequence;

[0031] A vibration mechanism is provided on each reciprocating lead screw 10. Each vibration mechanism includes a lead screw sleeve 18. Each lead screw sleeve 18 is threadedly connected to the corresponding reciprocating lead screw 10. A plurality of limiting rods 19 are fixedly installed on the bottom surface of each filtering disc 8, and each limiting rod 19 is slidably connected to the corresponding lead screw sleeve 18. One end of each limiting rod 19 is fixedly installed with a baffle 20, and the diameter length of each baffle 20 is greater than the diameter length of the limiting rod 19;

[0032] It should be noted that the lead screw sleeve 18 is limited by the limiting rod 19, so that it slides reciprocally;

[0033] A plurality of sliding rods 16 are elastically connected to the bottom surface of each filtering disc 8. A plurality of fixing plates 12 are fixedly installed on the bottom surface of each filtering disc 8, and each sliding rod 16 is slidably connected within the corresponding fixing plate 12. A return spring 14 is commonly installed between the bottom surface of each fixing plate 12 and the top surface of the corresponding first magnet 15;

[0034] It should be noted that the return spring 14 can reset the sliding rod 16;

[0035] One end of each sliding rod 16 is fixedly installed with a first magnet 15. A plurality of second magnets 17 are fixedly installed on the top surface of each lead screw sleeve 18. The top magnetic poles of each second magnet 17 are opposite to the bottom magnetic poles of the corresponding first magnets 15. One end of each sliding rod 16 away from the first magnet 15 is fixedly installed with an impact ball 13. The material of each impact ball 13 is rubber. The diameter length of each impact ball 13 is greater than the diameter length of the sliding rod 16, and each fixing plate 12 does not contact the bottom surface of the corresponding filtering disc 8. It is worth noting that the second magnet 17 can pull the first magnet 15 downward. When the suction force between the first magnet 15 and the second magnet 17 is less than the tensile force of the return spring 14, the first magnet 15 disengages, and then the impact ball 13 impacts the filtering disc 8, thereby shaking off the scale hidden in the pores and grooves of the filtering disc 8, so as to achieve a more thorough cleaning. At the same time, the rubber of the impact ball 13 is food-grade high-temperature resistant rubber.

[0036] When the utility model is in use, first, the heating device 4 can heat the external water source and transport it to a plurality of filter cylinders 7. Then, through the driving source in the driving box 2, the rotating shafts 9 in each filter cylinder 7 are driven to rotate. Each rotating shaft 9 drives the corresponding reciprocating lead screw 10 and a plurality of rotating shafts 9 to rotate synchronously. Then, through the arrangement of the rotating rod 11 and the spring telescopic rod 21, the cleaning plate 22 is always made to perform a circular motion around the rotating shaft 9, thereby cleaning the filtering disc 8. At the same time, the service life of the cleaning plate 22 can be extended through the spring telescopic rod 21;

[0037] When the reciprocating lead screw 10 rotates, through the arrangement of the limit rod 19 and the lead screw sleeve 18, a plurality of second magnets 17 are driven to slide up and down reciprocally. When the second magnet 17 contacts the first magnet 15, at this time, the second magnet 17 attracts the first magnet 15. Then the second magnet 17 moves downward, synchronously driving the first magnet 15 to move downward and stretching the return spring 14. When the restoring force of the return spring 14 is greater than the suction force between the second magnet 17 and the first magnet 15, the second magnet 17 separates from the first magnet 15. Under the action of the return spring 14, the first magnet 15 resets, simultaneously driving the impact ball 13 to slide. Then, through the impact of the impact ball 13 on the filter disc 8, vibration is generated, and thus the water scale hidden in the pores and grooves of the filter disc 8 is shaken off, so as to achieve a more thorough cleaning.

[0038] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
