Description

Technical Field

[0001] The utility model belongs to the technical field of boiler water recovery, and in particular relates to a filtering treatment device for boiler water recovery. Background Art

[0002] Industrial boilers are heat exchange devices that transfer heat released by fuel combustion to water, generating steam. Therefore, the quality of this water is crucial to the safe operation of the boiler, and boiler water treatment is a crucial issue. The goal of industrial boiler water treatment is to eliminate various boiler water issues and ensure safe operation.

[0003] Chinese patent CN222517906U discloses a filtering device for recovering high-temperature condensed water, comprising a shell, a filter screen cartridge disposed inside the shell, a sealing plate disposed at one end of the filter screen cartridge close to the water inlet of the shell, the diameter of the sealing plate matching the inner diameter of the shell; a water inlet hole is disposed on a portion of the sealing plate that is larger than the diameter of the filter screen cartridge; an end of the filter screen cartridge close to the water outlet of the shell is connected to the outlet at the end of the shell; a cleaning sleeve is rotatably disposed on the shell, and a cleaning brush is disposed in the cleaning sleeve to contact the outer wall of the filter screen cartridge.

[0004] At present, many companies are installing filter screens in the circulating pipes for high-temperature condensate recovery in order to achieve the purpose of cleaning solid dirt. Since the diameter of the circulating water pipe is not large, the filtering surface is small when this filtering method is used to filter the condensate, and the filter screen is easily covered by impurities, resulting in a sharp drop in filtering efficiency. Frequent disassembly and cleaning are required, which is more troublesome. In the above document, the cleaning sleeve is rotated to clean the filter cylinder and the inner wall of the shell without disassembly. However, if the flushing operation is to be performed at the same time, it is necessary to first rotate the cleaning sleeve counterclockwise to displace the sealing plate and the mounting plate to close the pipeline, and then open the valves on the water pipe and the drain pipe before cleaning. The cleaning sleeve can only be rotated in one direction. If the rotation direction is opposite, the sealing plate and the mounting plate will be connected, causing debris to enter other pipes. It is more troublesome to use and the cleaning effect is poor. Utility Model Content

[0005] In order to solve the problem that flushing requires many work processes and the cleaning sleeve can only rotate in one direction, resulting in poor cleaning effect, the utility model proposes a filtering and processing device for boiler water recovery to overcome the above technical problems existing in the existing related technologies.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a filtering and processing device for recycling boiler water, comprising a connecting pipe, a filtering assembly being arranged inside the connecting pipe, a brushing assembly and a flushing assembly being respectively arranged on the outer surface of the connecting pipe, a limiting assembly and a linkage assembly being respectively arranged on the outer surface of the flushing assembly, the filtering assembly being used for filtering boiler water passing through the connecting pipe, the brushing assembly being used for brushing off debris on the surface of the filtering assembly, the flushing assembly being used for flushing away debris on the filtering assembly, the limiting assembly being used for limiting the flushing assembly, and the linkage assembly being used for enabling the flushing assembly to close the passage between the connecting pipe and the filtering assembly while being open.

[0008] Further, the filter assembly includes a first fixed plate, which is fixedly connected to the inside of the connecting pipe, and the outer surface of the first fixed plate is rotatably connected to the first rotating plate, and the outer surfaces of the first fixed plate and the first rotating plate are both provided with a plurality of first through holes, and the outer surface of the first rotating plate is rotatably connected to the filter cartridge, and the filter cartridge is fixedly connected to the inside of the connecting pipe, and the end of the filter cartridge is rotatably connected to the second rotating plate, and the outer surface of the second rotating plate is rotatably connected to the second fixed plate, and the second fixed plate is fixedly connected to the inside of the connecting pipe, and the outer surfaces of the second rotating plate and the second fixed plate are both provided with a plurality of second through holes, the cross-sectional positions of several of the first through holes are located between the connecting pipe and the filter cartridge, and the cross-sectional positions of several of the second through holes are located inside the filter cartridge.

A handle is fixedly connected to the outer surface of the rotating tube, a connecting rod is fixedly connected to the inside of the rotating tube, and a cleaning brush is fixedly connected to the end of the connecting rod, which rests on the outer surface of the filter cartridge.

[0010] Furthermore, the flushing assembly includes a water inlet pipe and a drain pipe, and the water inlet pipe and the drain pipe are fixedly connected to the connecting pipe and are interconnected, and valves are fixedly installed on the outer surfaces of the water inlet pipe and the drain pipe.

[0011] Furthermore, the limiting assembly includes an insert rod, which is slidably connected to the valve, and the end of the insert rod is fixedly connected to a circular plate, one side of the circular plate is fixedly connected to a spring, and the other side of the circular plate is fixedly connected to a pull ring, the spring is fixedly connected to the valve, and a limiting hole is provided on the outer surface of the connecting pipe, and the insert rod passes through the valve handle and is plugged into the limiting hole.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model connects the valve and the rotating rod. The valve handle drives the rotating rod to rotate, and the rotating rod drives the gear to rotate. Through the engagement of the gear and the gear ring, the gear drives the gear ring and the first rotating plate to rotate, thereby changing the positions of the first through holes on the first rotating plate and the first fixed plate, making them staggered with each other, thereby realizing the cutting off of the flow of the connecting pipe while opening the valve, without the need for additional operation, reducing the operating steps, and making cleaning more convenient.

[0028] The following will clearly and completely describe the technical solutions in the utility model embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0030] See also Figure 1-Figure 7 As shown, the utility model is a filtering and processing device for boiler water recovery, comprising a connecting pipe 1, a filter assembly 2 is provided inside the connecting pipe 1, a brushing assembly 3 and a flushing assembly 4 are respectively provided on the outer surface of the connecting pipe 1, and a limiting assembly 5 and a linkage assembly 6 are respectively provided on the outer surface of the flushing assembly 4. The filter assembly 2 is used to filter the boiler water passing through the connecting pipe 1, the brushing assembly 3 is used to brush off debris on the surface of the filter assembly 2, the flushing assembly 4 is used to flush away the debris on the filter assembly 2, the limiting assembly 5 is used to limit the flushing assembly 4, and the linkage assembly 6 is used to enable the flushing assembly 4 to close the channel between the connecting pipe 1 and the filter assembly 2 while opening.

[0031] After the cleaning is completed, the flushing assembly 4 is closed, and the flushing assembly 4 opens the filter assembly 2 through the linkage assembly 6. At this time, the filter assembly 2 and the connecting pipe 1 are in a conductive state, and the boiler water recovery can continue.

[0032] The utility model connects the filter assembly 2 with the flushing assembly 4. When the flushing assembly 4 is rotated to open, the flushing assembly 4 drives the linkage assembly 6 to rotate, and the filter assembly 2 is driven to rotate synchronously through the linkage assembly 6. The water holes between the filter assembly 2 and the connecting pipe 1 are staggered with each other, so that an independent chamber exists in the connecting pipe 1 for easy cleaning. The connecting pipe 1 can be closed when the flushing assembly 4 is opened, without the need for additional operation, reducing the work steps, and making cleaning more convenient.

[0033] In one embodiment, for the above-mentioned filter assembly 2, the filter assembly 2 includes a first fixed plate 201, which is fixedly connected to the inside of the connecting pipe 1, and the outer surface of the first fixed plate 201 is rotatably connected to the first rotating plate 202. The outer surfaces of the first fixed plate 201 and the first rotating plate 202 are both provided with a plurality of first through holes 203. The outer surface of the first rotating plate 202 is rotatably connected to the filter cartridge 204, and the filter cartridge 204 is fixedly connected to the inside of the connecting pipe 1. The end of the filter cartridge 204 is rotatably connected to the second rotating plate 205, and the outer surface of the second rotating plate 205 is rotatably connected to the second fixed plate 206. The second fixed plate 206 is fixedly connected to the inside of the connecting pipe 1, and the outer surfaces of the second rotating plate 205 and the second fixed plate 206 are both provided with a plurality of second through holes 207. The cross-sectional positions of the plurality of first through holes 203 are located between the connecting pipe 1 and the filter cartridge 204, and the cross-sectional positions of the plurality of second through holes 207 are located inside the filter cartridge 204.

[0034] When the first through hole 203 on the first fixed plate 201 and the first rotating plate 202 are aligned, the boiler water in the connecting pipe 1 can pass through the first through hole 203 and enter between the filter cartridge 204 and the connecting pipe 1. The boiler water passes through the filter cartridge 204 and enters its interior, and debris is blocked between the filter cartridge 204 and the connecting pipe 1. The filtered boiler water can flow away from the second through hole 207 on the right side of the filter cartridge 204.

[0035] In one embodiment, for the above-mentioned brushing assembly 3, the brushing assembly 3 includes a rotating tube 301, which is rotatably connected to the connecting tube 1, and a handle 302 is fixedly connected to the outer surface of the rotating tube 301. A connecting rod 303 is fixedly connected to the inside of the rotating tube 301, and a cleaning brush 304 is fixedly connected to the end of the connecting rod 303, and the cleaning brush 304 is against the outer surface of the filter cartridge 204.

[0036] Push the handle 302, which drives the rotating tube 301 to rotate. The rotating tube 301 drives the cleaning brush 304 to rotate through the connecting rod 303. The multiple groups of cleaning brushes 304 reciprocate on the outer surface of the filter cartridge 204 to brush away debris on the filter cartridge 204.

[0037] Furthermore, when the handle 302 is pushed to drive the cleaning brush 304 to rotate, the rotation of the cleaning brush 304 is not linked with the first rotating plate 202 and the second rotating plate 205, and the connecting pipe 1 is always in a closed state. Therefore, the cleaning brush 304 can be rotated forward and reversed at will, and will not cause the cleaned dirt to enter other pipes. The alternating change of the rotation direction of the cleaning brush 304 breaks the adaptation of the flocs to the rotation direction, destroys their stable attachment form, and has a better cleaning effect.

[0038] In one embodiment, for the above-mentioned flushing component 4, the flushing component 4 includes a water inlet pipe 401 and a drain pipe 402, and the water inlet pipe 401 and the drain pipe 402 are fixedly connected to the connecting pipe 1 and are interconnected, and valves 403 are fixedly installed on the outer surfaces of the water inlet pipe 401 and the drain pipe 402.

[0039] When the connection pipe 1 and the filter cartridge 204 are closed, the valves 403 on the water inlet pipe 401 and the drain pipe 402 are opened, and clean water enters between the filter cartridge 204 and the connection pipe 1 from the water inlet pipe 401 to rinse the debris on the filter cartridge 204. The cleaning effect can be improved by using the cleaning brush 304, and the debris brushed off is discharged from the drain pipe 402 along with the sewage.

[0040] In one embodiment, for the above-mentioned limiting component 5, the limiting component 5 includes an insert rod 501, the insert rod 501 is slidingly connected to the valve 403, the end of the insert rod 501 is fixedly connected to a circular plate 502, one side of the circular plate 502 is fixedly connected to a spring 503, the other side of the circular plate 502 is fixedly connected to a pull ring 504, the spring 503 is fixedly connected to the valve 403, and a limiting hole 505 is opened on the outer surface of the connecting pipe 1, and the insert rod 501 passes through the handle of the valve 403 and is plugged into the limiting hole 505.

[0041] When the pull ring 504 is pulled, the pull ring 504 drives the circular plate 502 and the insertion rod 501 to move, so that the insertion rod 501 is separated from the limiting hole 505 on the connecting pipe 1. At the same time, the spring 503 is stretched, releasing the limiting fixation of the handle on the valve 403. At this time, the handle of the valve 403 can be pushed to rotate. After the valve 403 is opened, the pull ring 504 is released. The spring 503 can pull the circular plate 502 and the pull ring 504 to reset, and at the same time, the insertion rod 501 on the circular plate 502 is plugged into another set of limiting holes 505 to limit the valve 403.

[0042] In one embodiment, for the above-mentioned linkage assembly 6, the linkage assembly 6 includes a rotating rod 601, the rotating rod 601 is fixedly connected to the handle of the valve 403, the outer surface of the rotating rod 601 is fixedly connected to a gear 602, the outer surface of the gear 602 is meshed with a gear ring 603, and the gear ring 603 is fixedly connected to the first rotating plate 202.

[0043] By rotating the handle of valve 403 on water inlet pipe 401, the handle of valve 403 drives rotating rod 601, which in turn rotates gear 602. The meshing of gear 602 and gear ring 603 causes gear 602 to rotate the gear ring 603 and first rotating plate 202, thereby changing the position of first rotating plate 202 and first through-hole 203 on first fixed plate 201. Similarly, when valve 403 on drain pipe 402 rotates, it changes the position between second rotating plate 205 and second through-hole 207 on second fixed plate 206, thereby controlling the on / off state of connecting pipe 1.

[0044] In one embodiment, for the connecting pipe 1 , a connecting hole 7 is provided on the outer surface of the connecting pipe 1 .

[0045] The connection hole 7 facilitates the connection pipe 1 to be connected to other pipes by bolts.

[0046] Through the above technical solution, 1. by connecting the valve 403 with the rotating rod 601, the handle of the valve 403 drives the rotating rod 601 to rotate, and the rotating rod 601 drives the gear 602 to rotate. Through the meshing of the gear 602 and the gear ring 603, the gear 602 drives the gear ring 603 and the first rotating plate 202 to rotate, thereby changing the position of the first rotating plate 202 and the first through hole 203 on the first fixed plate 201, making them staggered, thereby opening the valve 403 and simultaneously cutting off the flow of the connecting pipe 1, without the need for additional operation, reducing the number of work steps, and making cleaning more convenient. 2. by connecting the valve 403 with the plug rod 501, when the plug rod 501 is plugged into the connecting pipe 1, the plug rod 501 can block the rotation of the valve 403, implementing a position limit for the valve 403, preventing the filter cartridge 204 from rotating unnecessarily due to water flow impacting the filter cartridge 204, thereby affecting the valve 403 and causing it to rotate and reduce the water flow.
