DETAILED DESCRIPTION

[0026] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0027] First embodiment

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic structural diagram of a first embodiment of a device for reducing dissolved oxygen in condensed water provided by the utility model; Figure 2 for Figure 1 The structural schematic diagram of the filter box shown; Figure 3 for Figure 2 A schematic diagram of the structure of the interior of the filter box shown; Figure 4 for Figure 2 A device for reducing dissolved oxygen in condensed water comprises:

[0029] A condensate pump 1, wherein a filter box 2 is disposed at one end of the condensate pump 1, a water inlet pipe 3 is disposed at one end of the filter box 2, a filter screen 5 is disposed inside the filter box 2, and a limit block 6 is fixedly connected to the inner wall surface of the filter box 2;

[0030] The filter box 2 is internally rotatably connected with a rotating rod 4, a torsion spring 41 is sleeved on the surface of the rotating rod 4, and a rotating plate 42 is fixedly connected to one side of the rotating rod 4;

[0031] A support plate 7 is fixedly connected to the inside of the filter box 2, a feed port 8 is opened inside the support plate 7, an extension slot 71 is opened inside the support plate 7, an extension plate 72 is slidably connected inside the extension slot 71, a tooth plate 73 is fixedly connected to the top of the extension plate 72, a gear 74 is meshed on the surface of the tooth plate 73, and a diversion port 9 is opened inside the extension plate 72;

[0032] A baffle 10 is disposed at the bottom of the filter box 2 , and a limiting member 11 is disposed inside the baffle 10 .

[0033] A mounting plate 12 is disposed at the bottom of the condensate pump 1 , and a plurality of mounting holes 13 are formed inside the mounting plate 12 .

[0034] The filter screen 5 is in an arc shape and rotates along the same path as the rotating plate 42 . When the rotating plate 42 rotates to one side, one end of the rotating plate 42 contacts one side of the filter screen 5 .

[0035] The limit block 6 is used to limit the rotating plate 42 after it is reset. After the torsion spring 41 is reset, it drives the rotating plate 42 connected to the rotating rod 4 to rotate to one side. When one side of the rotating plate 42 contacts one side of the limit block 6, the rotating plate 42 is limited.

[0036] One end of the water inlet pipe 3 is fixedly installed on one side of the filter box 2 and at an upper position, so as to push the rotating plate 42 to rotate to one side when the water in the water inlet pipe 3 enters the filter box 2 .

[0037] The two ends of the rotating rod 4 are rotatably connected to the two sides inside the filter box 2 through a rotating shaft.

[0038] A limiting plate is fixedly installed inside the filter box 2 , and two ends of the two torsion springs 41 are fixedly connected to the inside of the rotating plate 42 and the other ends are fixedly connected to the inside of the limiting plate.

[0039] The gear 74 is fixedly mounted on the surface of the rotating rod 4, and the surface of the gear 74 is meshed with the tooth plate 73, which is used to drive the rotating rod 4 to rotate to one side when the rotating plate 42 rotates to one side, thereby driving the gear 74 to rotate to one side, so that the tooth plate 72 connected to the extension plate 72 moves to one side inside the extension groove 71.

[0040] The support plate 7 and the extension plate 72 are both provided with diversion ports 9. When the extension plate 72 moves to one side, the diversion ports 9 and the feed port 8 are sealed by the extension plate 72. At this time, the water above the support plate 7 inside the filter box 2 cannot enter the bottom of the filter box 2.

[0041] Meanwhile, the extension plate 72 is an L-shaped plate, which is used to seal the filter screen fixedly installed inside the filter box 2 after the extension plate 72 is reset, so as to remove the baffle 10 and reduce the outflow of water when cleaning the inside of the filter box 2.

[0042] The limiting member 11 includes a limiting hole, the internal thread of the limiting hole is connected to a limiting pin, and the limiting pin is a bolt. Multiple limiting holes are opened inside the baffle 10 and the filter box 2, which are used to fix the baffle 10 and the filter box 2 after the limiting pin is installed inside the limiting hole.

[0044] The working principle of the device for reducing dissolved oxygen in condensed water provided by the utility model is as follows:

[0045] When in use, after starting the condensate pump 1, water enters the interior of the filter box 2 through the water inlet pipe 3, and the water pushes the rotating plate 42 to drive the rotating rod 4 to rotate to one side while tightening the torsion spring 41, and the rotating plate 42 rotates to one side to filter the filter screen 5. At the same time, when the rotating plate 42 moves to one side, it drives the gear 74 to rotate to one side, thereby driving the toothed plate 73 connected to the extension plate 72 to move to one side inside the extension groove 71. After the rotating plate 42 rotates to one side to a suitable position, the diversion port 9 inside the support plate 7 overlaps with the diversion port 9 inside the extension plate 72, so that part of the water will be diverted to the bottom of the filter box 2, and the impurities scraped by the rotating plate 42 will enter the interior of the filter box 2 through the opened feed port, and at the same time, the water entering through the diversion port 9 takes away the filter screen fixedly installed inside the box body of the filter box 2 for filtering and storage, and the filtered water enters the interior of the condensate pump 1.

[0046] After the water stops, the torsion spring 41 resets and drives the rotating plate 42 connected to the rotating rod 4 to rotate to one side, thereby driving the gear 74 to rotate to one side, so that the tooth plate 74 connected to the extension plate 72 moves to one side inside the extension groove 71, and after the diversion port 9 inside the support plate 7 and the diversion port 9 inside the extension plate 72 are staggered, the diversion port 9 and the feed port 8 are sealed by the extension plate 72, and at the same time, the filter screen fixedly installed inside the filter box 2 is sealed, so that the filter screen 5 is automatically cleaned by the rotating plate 42.

[0047] Compared with the related art, the device for reducing dissolved oxygen in condensed water provided by the utility model has the following beneficial effects:

[0048] The utility model provides a device for reducing dissolved oxygen in condensed water. After water enters the interior of the filter box 2 through the water inlet pipe 3, it drives the rotating plate 42 connected to the rotating rod 4 to rotate to one side, so that the filter screen 5 is cleaned by the rotating plate 42 to prevent the filter screen 5 from being blocked. At the same time, when the rotating rod 4 rotates to one side, it drives the gear 74 to mesh with the toothed plate 73 to move to one side, so that the extension plate 72 moves to one side, so that the feed port 8 and the diversion port 9 are opened, and the impurities scraped off by the rotating plate 42 are stored.
