Description

Technical Field

[0001] This utility model relates to the field of heat exchanger fouling cleaning technology, and in particular to a ball cleaning device. Background Technology

[0002] Heat exchangers are the main heat exchange equipment in the heating and cooling field. After the system has been running for a long time, sludge and dissolved salts in the cooling water will be deposited on the inner wall of the heat exchange tubes. The accumulated scale will not only affect the heat exchange efficiency, but also increase the resistance of cooling water transportation and increase the energy consumption of the system. Therefore, it is necessary to clean the heat transfer pipes regularly.

[0003] Rubber ball cleaning is a common cleaning method. The rubber balls used are elastic. When cooling water pushes the rubber balls into the pipe, the rubber balls will abut against the inner wall of the pipe to scrub and remove sludge.

[0004] Existing ball cleaning devices can be divided into end-cap type and external type. End-cap type devices are integrated with the end cap of the heat exchanger. For example, CN110763075A discloses a heat exchanger end cap integrated with a ball cleaning device, where a cleaning mechanism is installed between the outlet and inlet pipes of the end cap. This type has advantages such as small footprint and no need for on-site installation. External type devices are independent of the heat exchanger and are generally installed near the heat exchanger. They work in conjunction with ball collectors installed on the pipes to complete the ball cleaning function. For example, CN108871045A discloses an online condenser cleaning system that uses ball collectors and ball dischargers installed on the condenser to achieve online cleaning of the heat exchange tubes. Both end-cap type and external type rubber ball cleaning devices use vertical booster pumps with inlet and outlet oriented at 180°. They require upper and lower bends to connect to the outlet and inlet pipes (ball collection and discharging tubes), limiting their applicability to structures with a significant distance between the outlet and inlet pipes. For example, the conventional vertical booster pump used in this device has an inlet and outlet length of at least 220mm, and the total vertical length of the upper and lower bends is at least 150mm. Therefore, it is only suitable for structures where the distance between the outlet and inlet pipes (ball collection and discharging tubes) is greater than or equal to 370mm. This presents certain limitations in practical applications, as the structure requires high dimensional accuracy and demanding manual splicing and welding techniques. Utility Model Content

[0045] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0047] In the description of this utility model, it should be understood that the terms "connected," "linked," and "fixed," etc., used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or a welded connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a connection within two components or an interaction between two components, unless otherwise explicitly defined. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0048] First embodiment:

[0049] like Figures 1 to 5As shown, the first embodiment of this utility model provides a rubber ball cleaning device, including a pressurizing component 10 and a ball storage container 20 for collecting rubber balls. The pressurizing component 10 includes a horizontal pump 11, a first pressurizing pipe 12 and a second pressurizing pipe 13. The first end of the first pressurizing pipe 12 is connected to the inlet of the horizontal pump 11, and the first end of the second pressurizing pipe 13 is connected to the outlet of the horizontal pump 11. The first end of the first pressurizing pipe 12 and the first end of the second pressurizing pipe 13 form a communication structure with an included angle. The second end of the first pressurizing pipe 12 is connected to the ball storage container 20 to enhance the water flow through the ball storage container 20.

[0050] Based on the above-mentioned technical features, the ball cleaning device's pressurization component 10 enhances the water flow through the ball storage container 20, effectively improving the ball collection / launch efficiency. The pressurization pump is a horizontal pump 11, forming an angled connection between the first pressurization pipe 12 and the second pressurization pipe 13 connected to the inlet and outlet of the horizontal pump 11. This effectively shortens the total vertical length, resulting in a more compact pipe layout for the cleaning device. It is suitable for structures where the distance between the outlet and inlet pipes of heat exchange equipment is small, significantly reducing the limitations of the ball cleaning device and lowering production assembly requirements. It offers advantages such as low production cost and wide applicability.

[0051] The aforementioned vertical direction refers to the direction of the shortest distance between the central axes of the outlet and inlet pipes of conventional heat exchange equipment, where the outlet and inlet pipes are horizontally and vertically arranged (see attached diagram). Figure 6 and attached Figure 7 (Orientation of placement). It is understandable that when the outlet and inlet pipes of the heat exchanger are used in other placement states (e.g., the inlet and outlet pipes are vertical pipes), the shortest distance between the central axes of the two pipes is also in the vertical direction.

[0052] In this embodiment, the connecting structure is a right-angle connecting structure, which means that the inlet and outlet of the horizontal pump 11 are oriented at 90°. Compared with a vertical pump of the same power, the inlet and outlet of the horizontal pump 11 occupy a shorter length in the vertical direction, and the number of bends can be reduced. This further makes it suitable for structures with a smaller distance between the outlet and inlet pipes of heat exchange equipment.

[0053] In this embodiment, as Figure 1As shown, the first booster pipe 12 is an L-shaped pipe so that the first booster pipe 12 and the second booster pipe 13 form a U-shaped structure, which facilitates the splicing and installation of the first booster pipe 12 and the second booster pipe 13 using conventional standard pipes. For the booster assembly 10, only the first booster pipe 12 needs to be bent to form an L-shaped structure, and the second booster pipe 13 can be a conventional straight pipe, which significantly reduces material costs, assembly time and installation requirements.

[0054] In this embodiment, to enhance the water flow through the ball storage container 20 during both ball collection and ball delivery processes, the second end of the first booster pipe 12 and the second end of the second booster pipe 13 are connected to the inlet and outlet 22 of the ball storage container 20 to form a first three-way structure 30, thereby enhancing the water flow through the ball storage container 20 during both the ball delivery and ball collection processes. Specifically, during the ball collection process, the first three-way structure 30 connects the first booster pipe 12 to the inlet and outlet 22 of the ball storage container 20; during the ball delivery process, the first three-way structure 30 connects the second booster pipe 13 to the inlet and outlet 22 of the ball storage container 20.

[0055] The ball storage container 20 is equipped with a filter screen inside, which can trap the rubber balls, keeping them inside the container while the water continues to flow out through the inlet and outlet 22, thus separating the rubber balls from the water. A detachable viewing mirror 23 is provided at one end of the ball storage container 20 for replacing the rubber balls inside.

[0056] In this embodiment, combined with Figure 1 and Figure 3 As shown, it also includes a first connecting pipe 40 for connecting to the outlet water pipe of the heat exchange equipment. The first connecting pipe 40 is provided with a ball receiving pipe 41 and a ball receiving filter screen 42. One end of the ball receiving pipe 41 is connected to the first connecting pipe 40 and communicates with the ball receiving filter screen 42 inside it. The other end of the ball receiving pipe 41 is connected to the ball inlet / outlet 21 of the ball storage container 20. Specifically, the first connecting pipe 40 is provided with a conical ball receiving filter screen 42 inside. The ball receiving filter screen 42 collects the rubber balls in the first connecting pipe 40 into the ball receiving pipe 41, so that the rubber balls finally enter the ball storage container 20. The first connecting pipe 40 is a straight pipe (two-way pipe) with the same diameter as the outlet water pipe, and flange holes are provided at both ends for detachable connection.

[0057] Furthermore, the device also includes an installation pipe assembly 50 for adapting to the second connecting pipe 90. The pressurization assembly 10 and the ball storage container 20 are connected to the wall of the second connecting pipe 90 through the installation pipe assembly 50 to deliver the glue balls into the second connecting pipe 90. During installation, the wall of the second connecting pipe 90 needs to be drilled on-site before the installation pipe assembly 50 is installed, thus connecting the installation pipe assembly 50 and the second connecting pipe 90. Since the installation pipe assembly 50 is used to deliver the glue balls, its pipe diameter is much smaller than that of the first connecting pipe 40 and the second connecting pipe 90, making it easier to adjust the pipe length, installation position, and angle on-site, greatly reducing installation requirements. Even if there are differences in the spacing, length, and other dimensions between the outlet and inlet pipes of different heat exchangers, the first connecting pipe 40 and the second connecting pipe 90 can be quickly connected to the heat exchanger, expanding its applicability. Since the ball cleaning device is installed on existing heat exchange equipment, it is generally installed by cutting off the original outlet and inlet pipes of the heat exchange equipment and then connecting the first connecting pipe 40 and the second connecting pipe 90 to the outlet and inlet pipes respectively. There are no restrictions on the installation location. A filter component can also be installed inside the second connecting pipe 90 to filter impurities and prevent them from entering the heat exchange equipment.

[0058] In this embodiment, the mounting tube assembly 50 includes a first mounting hose 51 and a second mounting hose 52. One end of the first mounting hose 51 and the other end of the ball receiving tube 41 are connected to the ball inlet / outlet 21 of the ball storage container 20 to form a second tee structure 60. The other end of the first mounting hose 51 is mounted on the wall of the second connecting tube 90. The first mounting hose 51 has flexible characteristics, providing better flexibility and freedom in adjusting the installation position, and is further adaptable to different opening positions or angles on the walls of different second connecting tubes 90, thus reducing installation requirements.

[0059] In this embodiment, the mounting tube assembly 50 is a dual-pipe structure, comprising a first mounting hose 51 and a second mounting hose 52. The first mounting hose 51 serves as the serving conduit, and the second mounting hose 52 serves as the water inlet conduit. Water from the second connecting pipe 90 is introduced through the second mounting hose 52. After entering the ball storage container 20, the water pressure pushes the ball into the first mounting hose 51, thus launching the ball. It is understood that the mounting tube assembly 50 can also be a single-pipe structure, consisting only of the first mounting hose 51. In this case, the horizontal pump 11 only needs to be connected to the ball storage container 20 through the second end of the first booster pipe 12. The ball enters the first mounting hose 51 using an external driving source, or a switch valve can be installed on the first mounting hose 51. When the switch valve is opened, the ball enters the first mounting hose 51 using its own gravity, thus launching the ball.

[0060] In this embodiment, one end of the second installation hose 52, the first end of the first tee structure 30, and the second end of the first booster pipe 12 are connected to form a third tee structure 70. The other end of the second installation hose 52 is installed on the wall of the second connecting pipe 90. The second installation hose 52 can introduce water flow into the second connecting pipe 90, and the water flow pressure pushes the rubber ball into the first installation hose 51. Similarly, the second installation hose 52 has flexible characteristics, providing better flexibility and freedom in adjusting the installation position. It can adapt to different opening positions or angles on the wall of the second connecting pipe 90, reducing installation requirements.

[0061] The second three-way structure 60 is equipped with a first three-way valve 61. During the serve, the first three-way valve 61 controls the first mounting hose 51 to connect with the inlet / outlet 21 of the ball storage container 20, sending the rubber ball into the first mounting hose 51. During the collect process, the first three-way valve 61 controls the collect pipe 41 to connect with the inlet / outlet 21 of the ball storage container 20, collecting the cleaned rubber ball into the ball storage container 20. The third three-way structure 70 is equipped with a second three-way valve 71. During the serve, the second three-way valve 71 controls the second mounting hose 52 to connect with the first booster pipe 12, allowing the horizontal pump 11 to introduce water from the second connecting pipe 90 for the serve. During the collect process, the second three-way valve 71 controls the first booster pipe 12 to connect with the first three-way structure 30, discharging the water separated from the ball storage container 20. In addition, the first installation hose 51 is also equipped with a maintenance valve 53. When the rubber ball cleaning device needs maintenance, the first three-way valve 61 and the maintenance valve 53 together shut off the water flow.

[0062] In this embodiment, the first installation hose 51 and the second installation hose 52 are respectively welded to the wall of the second connecting pipe 90 so that the first installation hose 51 and the second installation hose 52 are respectively connected to the second connecting pipe 90. At the installation site, a hole (DN50) is made in the wall of the second connecting pipe 90, and then the first installation hose 51 and the second installation hose 52 are fixedly welded to the hole using welding equipment.

[0063] To achieve detachability, the first installation hose 51 and the second installation hose 52 can each be fitted with a connecting joint between them and the wall of the second connecting pipe 90. This connecting joint facilitates detachable connection and equipment maintenance. For example, the connecting joint can be a standard connecting flange (DN50), welded to a hole in the pipe wall. The ends of the first installation hose 51 and the second installation hose 52 are also fixed with corresponding connecting flanges (welded or threaded connections, etc.). The two connecting flanges are then detachably connected using standard components such as connecting bolts, nuts, and sealing rings.

[0064] In this embodiment, the first installation hose 51 and the second installation hose 52 are preferably made of stainless steel metal hoses, which have good corrosion resistance and can withstand large water pressure. It is understood that the first installation hose 51 and the second installation hose 52 can also be made of hoses of other composite materials, as long as they can withstand the corresponding water pressure, and no special restrictions are made here.

[0065] In this embodiment, the first connecting pipe 40 is provided with a drain pipe 43. One end of the drain pipe 43 is connected to the first connecting pipe 40, and the other end of the drain pipe 43, the second end of the first three-way structure 30, and the second end of the second pressurizing pipe 13 are connected to form a fourth three-way structure 80. The fourth three-way structure 80 is provided with a third three-way valve 81. During the ball receiving process, the third three-way valve 81 controls the drain pipe 43 to communicate with the second pressurizing pipe 13. When the ball enters the ball storage container 20, the filter screen of the ball storage container 20 can separate the ball and the water flow. The separated water flow flows back to the first connecting pipe 40 through the second pressurizing pipe 13 and the drain pipe 43. During the ball serving process, the third three-way valve 81 controls the second pressurizing pipe 13 to communicate with the first three-way structure 30. The water flow introduced from the second connecting pipe 90 enters the ball storage container 20, driving the ball into the first installation hose 51.

[0066] In this embodiment, the third end of the first three-way structure 30 is connected to the inlet / outlet 22 of the ball storage container 20 by a connecting hose 31. The connecting hose 31 is also a metal hose, possessing good corrosion resistance and the ability to withstand high water pressure. Since the first connecting pipe 40 requires two holes for fixing the ball receiving pipe 41 and the drain pipe 43, the connecting hose 31's flexibility facilitates adjustment of the relative installation positions of the ball receiving pipe 41 and the drain pipe 43. Even if there is a deviation in the hole position of the first connecting pipe 40, it does not affect the assembly of the ball receiving pipe 41 and the drain pipe 43, further reducing production difficulty. It is understood that the first connecting pipe 40 can also be made of other composite materials, as long as it can withstand the corresponding water pressure; no special restrictions are imposed here.

[0067] The following is the working process of the rubber ball cleaning device in this embodiment:

[0068] Serving process: as follows Figure 4 As shown, the first three-way valve 61 controls the ball inlet / outlet 21 of the ball storage container 20 to connect with the first mounting hose 51; the second three-way valve 71 controls the second mounting hose 52 to connect with the first booster pipe 12; and the third three-way valve 81 controls the second booster pipe 13 to connect with the water inlet / outlet 22 of the ball storage container 20. Under the action of the booster pump, the water flow from the second connecting pipe 90 sequentially enters the second mounting hose 52, the first booster pipe 12, the horizontal pump 11, the second booster pipe 13, the connecting hose 31, the ball storage container 20 (carrying away the rubber balls), and the first mounting hose 51. Finally, the water flow carries the rubber balls into the second connecting pipe 90, realizing the ball launch.

[0069] The process of collecting the ball: as follows Figure 5 As shown, the first three-way valve 61 controls the ball inlet / outlet 21 of the ball storage container 20 to connect with the ball collection pipe 41; the second three-way valve 71 controls the water inlet / outlet 22 of the ball storage container 20 to connect with the first booster pipe 12; and the third three-way valve 81 controls the second booster pipe 13 to connect with the drain pipe 43. The ball collection filter 42 blocks the rubber balls in the first connecting pipe 40. Driven by the horizontal pump 11, the water flow carries the rubber balls sequentially into the ball collection pipe 41, the ball storage container 20 (separating the rubber balls), the connecting hose 31, the first booster pipe 12, the second booster pipe 13, and the drain pipe 43. Finally, the water flow returns to the first connecting pipe 40, while the rubber balls remain on the ball storage container 20, thus achieving ball collection.

[0070] Second embodiment:

[0071] like Figure 6 and Figure 7 As shown, the difference between this embodiment and the first embodiment is that only the first connecting pipe 40 is used, and the mounting pipe assembly 50 is directly installed on the inlet pipe of the heat exchange equipment. The other components and working principles are the same, and will not be described again here.

[0072] In this embodiment, during the installation of the rubber ball cleaning device, it is only necessary to cut off the original outlet pipe of the heat exchange equipment, and then attach the first connecting pipe 40 to the outlet pipe. A hole is then drilled in the wall of the inlet pipe on-site, and the installation pipe assembly 50 is installed, connecting the installation pipe assembly 50 to the inlet pipe. Since the installation pipe assembly 50 is used to deliver the rubber balls, its pipe diameter is much smaller than that of the first connecting pipe 40 and the inlet pipe, making it easier to adjust the pipe length, installation position, and angle on-site, greatly reducing installation requirements. Compared to the first embodiment, this rubber ball cleaning device uses only a large-diameter first connecting pipe 40, resulting in a simpler structure and significantly reduced production costs. Even if there are differences in the spacing, length, and other dimensions between the outlet and inlet pipes of different heat exchange equipment, it will not affect the installation of the installation pipe assembly 50 onto the wall of the inlet pipe, further expanding its applicability.

[0073] Furthermore, the installation pipe assembly 50 includes a first installation hose 51 and a second installation hose 52 fixed on the wall of the water inlet pipe. The material properties, working principle, installation method, etc. of the hose are the same as those of the first embodiment, which can also effectively reduce the installation requirements. The specific structure will not be described in detail here.

[0074] Third embodiment:

[0075] like Figure 8 and Figure 9 As shown, the difference between this embodiment and the first embodiment is that the first connecting pipe 40 has a different structure. The other components and working principles are the same, and will not be described again here.

[0076] In this embodiment, the first connecting pipe 40 is a three-way pipe, preferably a Y-shaped pipe. The upper inlet and one of the outlets are used to connect to the water outlet pipe of the heat exchange equipment, and the lower outlet is connected to the ball receiving pipe 41. The first connecting pipe 40 is provided with a baffle net 44 to separate the water flow and the rubber balls and direct them to different outlets. The outlet for collecting the rubber balls is set downwards, so that the rubber balls fall quickly by their own weight, avoiding affecting the delivery efficiency of the water outlet pipe and ensuring the normal operation of the existing heat exchange equipment.

[0077] It is understandable that the first connecting pipe 40 can also be a T-shaped pipe or a special-shaped tee pipe to achieve the same purpose of ensuring the normal operation of the heat exchange equipment. Its specific structure will not be described in detail here.

[0078] In summary, the three embodiments of this utility model provide a rubber ball cleaning device with the following advantages: (1) Utilizing the structural characteristics of the horizontal pump 11, the first booster pipe 12 and the second booster pipe 13 connected to it form a connected structure with an included angle, making the pipe layout of the cleaning device more compact and having advantages such as low production cost and wide applicability. (2) Directly connecting the installation pipe assembly 50 to the second connecting pipe 90 or the pipe wall of the inlet pipe not only reduces the installation requirements but also allows for the adaptation to more different heat exchange equipment. Furthermore, the entire device can choose to use only the first connecting pipe 40 with a large diameter, making the structure simpler and further reducing production costs and difficulty. (3) The first installation hose 51, the second installation hose 52, and the connecting hose 31 are all metal hoses, which have better flexibility and freedom in adjusting the installation position, further reducing installation requirements.
