Description

Technical Field

[0001] This utility model relates to the field of filtration, and more specifically, to a filtration structure for a boiler condensate recovery machine. Background Technology

[0002] A boiler condensate recovery unit is a device specifically designed to collect and treat condensate generated during boiler operation. When the steam generated by the boiler is cooled and turns into liquid water after use, this water is called condensate. A boiler condensate recovery unit generally includes components such as a condensate collection device, filter, oil separator, condensate pump, heat exchanger, storage tank, and buffer tank. To prevent impurities in the condensate from damaging the equipment, the filter is usually installed at the inlet of the condensate pump and storage tank. Most existing filters are fixedly installed between the inlet and the condensate pump. Maintaining the filter plates inside the filter is relatively cumbersome, often requiring the entire filter to be disassembled for cleaning or replacement. Filter plate maintenance requires machine shutdown, and this cumbersome process leads to extended maintenance time, which reduces production efficiency to some extent.

[0003] Based on the above, the purpose of this utility model is to provide a filter structure for a boiler condensate recovery machine to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a filter structure for a boiler condensate recovery machine. This utility model involves setting inlet and outlet pipes on both sides of a support frame, and then setting a connecting pipe and a drive mechanism to move the connecting pipe between the inlet and outlet pipes. The filter plate is set on the connecting pipe. When it is necessary to clean or replace the filter plate, the drive mechanism drives the connecting pipe to move until a space is created between the connecting pipe and the inlet pipe for replacing the filter plate and rinsing the inlet pipe. This design makes filter plate replacement more convenient.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a filter structure for a boiler condensate recovery machine, including a support frame, with an inlet pipe and an outlet pipe fixedly connected to both ends of the support frame, a connecting pipe with one end slidably connected to the outlet pipe, and the other end of the connecting pipe abutting against the inlet pipe, both the inlet pipe and the outlet pipe having a snap-fit ​​part connected to the connecting pipe, a sealing gasket fixedly connected to each snap-fit ​​part, a mounting frame fixedly connected to the connecting pipe, a filter plate detachably connected to the mounting frame, and a drive mechanism for moving the connecting pipe on the support frame.

[0006] By adopting the above technical solution, when using the filter structure, the outlet pipe is fixedly connected to the inlet of the condensate pump or water storage tank, and the inlet pipe is fixedly connected to the water supply equipment. Condensate will pass through the inlet pipe, filter plate, connecting pipe, and outlet pipe in sequence, and the filter plate will filter the condensate. When it is necessary to clean or replace the filter plate, the connecting pipe is driven by the drive mechanism to move towards the outlet pipe until there is enough space between the outlet pipe and the inlet pipe. At this time, the user can remove and replace the filter plate. The user can also use a water hose to rinse the inlet pipe. After cleaning or replacing the filter plate, the connecting pipe is driven by the drive mechanism to move towards the inlet pipe until it can no longer move. The sealing gasket will cooperate with the snap-fit ​​part to achieve a waterproof effect.

[0007] The present invention is further configured such that: the driving mechanism includes a plurality of screws, one end of which is rotatably connected to the connecting pipe, and the other end of the screws is threadedly connected to the support frame.

[0008] The present invention is further configured such that a plurality of push rods are fixedly connected to the water outlet pipe.

[0009] The present invention is further configured such that: a plurality of limiting blocks are fixedly connected to the mounting bracket, and the filter plate is provided with a limiting groove for the limiting blocks to be inserted.

[0010] The present invention is further configured such that: an installation column is fixedly connected inside the water inlet pipe, a propeller is rotatably connected to the installation column, a reducer is provided inside the installation column, the propeller is fixedly connected to the input end of the reducer, an installation disk is fixedly connected to the output end of the reducer, and a plurality of scrapers are fixedly connected to the installation disk, the scrapers being in contact with the filter plate.

[0011] The present invention is further configured such that: a planar bearing is mounted on the mounting plate, and the planar bearing abuts against the mounting bracket.

[0012] In summary, this utility model has the following beneficial effects:

[0013] This invention features an inlet and outlet water pipe on both sides of a support frame, with a connecting pipe and a drive mechanism between them. A filter plate is mounted on the connecting pipe. When cleaning or replacing the filter plate is required, the drive mechanism moves the connecting pipe until space is available between the connecting pipe and the inlet pipe for replacing the filter plate and rinsing the inlet pipe. During this process, the filter plate is pushed away from the mounting frame by a push rod, making filter plate removal easier. A propeller and reducer are also installed inside the inlet pipe. The reducer has a mounting plate and multiple scrapers. Flowing condensate drives the propeller to rotate, and the propeller, through the reducer and mounting plate, drives the multiple scrapers to scrape away impurities from the filter plate, preventing impurities from clogging the filter holes. This design makes filter plate replacement more convenient. Attached Figure Description

[0023] A filter structure for a boiler condensate recovery machine, such as Figures 1-4 As shown, the device includes a support frame 3, with an inlet pipe 1 and an outlet pipe 2 fixedly connected to both ends of the support frame 3. The outlet pipe 2 is provided with a connecting pipe 4, one end of which is slidably connected to it. The connecting pipe is trumpet-shaped, with the smaller diameter end of the connecting pipe slidably connected to the outlet pipe. The other end of the connecting pipe 4 abuts against the inlet pipe 1. Both the inlet pipe 1 and the outlet pipe 2 are provided with a snap-fit ​​part 5 that connects to the connecting pipe 4. The snap-fit ​​part can be processed into a stepped shape. A sealing gasket 6 is fixedly connected to the snap-fit ​​part. A mounting bracket 18 is fixedly connected to the connecting pipe 4. A filter plate 17 is detachably connected to the mounting bracket 18. The support frame 3 is provided with a drive mechanism for moving the connecting pipe 4.

[0024] Furthermore, the drive mechanism includes several screws 7, one end of which is rotatably connected to the connecting pipe 4, and the other end of the screws 7 is threadedly connected to the support frame 3. Several fastening nuts are fitted on the screws.

[0025] Furthermore, several push rods 8 are fixedly connected to the water outlet pipe 2.

[0026] Furthermore, several limiting blocks 9 are fixedly connected to the mounting bracket 18, and the filter plate 17 is provided with limiting grooves 10 for the limiting blocks 9 to be inserted into, with the limiting blocks and limiting grooves fitting tightly together.

[0027] Furthermore, a mounting column 11 is fixedly connected inside the water inlet pipe 1, a propeller 12 is rotatably connected to the mounting column 11, a reducer 13 is installed inside the mounting column 11, the propeller 12 is fixedly connected to the input end of the reducer 13, a mounting plate 14 is fixedly connected to the output end of the reducer 13, the mounting plate is fixedly connected to the output shaft of the reducer by bolts, and several scrapers 15 are fixedly connected to the mounting plate 14, the scrapers 15 are in contact with the surface of the filter plate 17.

[0028] Furthermore, a flat bearing 16 is mounted on the mounting plate 14, and the flat bearing 16 abuts against the mounting bracket 18.

[0029] It should be mentioned that if components such as propellers and scrapers are not installed, a base plate can be installed at the position of the mounting plate to abut against the mounting frame. Multiple support legs are installed on the base plate, with one end fixedly connected to it. The other end of the support legs is fixedly connected to the water inlet pipe.

[0030] Working principle: When using the filter structure, the outlet pipe 2 is fixedly connected to the inlet of the condensate pump or water storage tank, and the inlet pipe 1 is fixedly connected to the water supply equipment. The condensate will pass through the inlet pipe 1, filter plate 17, connecting pipe 4 and outlet pipe 2 in sequence. The filter plate 17 will filter the condensate. In this process, the flowing condensate will drive the propeller 12 to rotate. The propeller 12 will drive the mounting plate 14 to rotate slowly through the reducer 13, thereby driving the scraper 15 to scrape off the impurities on the filter plate 17 to prevent impurities from clogging the filter holes.

[0031] When it is necessary to clean or replace the filter plate 17, rotate the screw 7, which will drive the connecting pipe 4 to move towards the outlet pipe 2 until there is enough space between the outlet pipe 2 and the inlet pipe 1. During this process, the filter plate 17 will be pushed away from the mounting bracket 18 by the push rod 8. At this time, the user can replace the filter plate 17, or remove the mounting plate 14 to maintain the filter plate 17, or use a water pipe to rinse the inlet pipe 1. After cleaning or replacing the filter plate 17, drive the connecting pipe 4 towards the inlet pipe 1 through the screw 7 until it can no longer move. The sealing gasket 6 will cooperate with the snap-fit ​​part 5 to achieve a waterproof effect.
