Description

Technical Field

[0001] This utility model relates to the field of heat exchange station technology, and more specifically, to a dirt remover for heat exchange stations. Background Technology

[0002] Heat exchange stations are key facilities in centralized heating systems. Their main function is to convert high-temperature heat medium (steam or high-temperature water) generated by heat sources (such as power plants or boiler rooms) into low-temperature hot water suitable for users through heat exchange, and then distribute it to residential communities or units. The water used for heat exchange will contain certain impurities. These impurities can cause blockages and wear in the pipes, so it is necessary to remove the impurities from the water.

[0003] A search revealed that utility model patent CN219701258U discloses a dirt separator for heat exchange stations. This dirt separator includes a discharge chamber with concave filter screens fixedly connected to both inner walls of the discharge chamber, and a spiral blade rotatably connected to one inner wall of the discharge chamber. Two connecting plates are fixedly connected to the upper and lower ends of the discharge chamber, respectively. Two straight connecting pipes are fixedly connected to the top of one connecting plate. Fine dirt that does not flow into the L-shaped connecting pipe is replaced by wastewater that flows to a Y-shaped connecting pipe, which then transmits the wastewater to a convex connecting pipe. The convex connecting pipe and the L-shaped connecting pipe are connected, and the L-shaped connecting pipe then directs the wastewater to a collection box. A square filter screen isolates impurities, while the wastewater is collected in the collection box. This method thoroughly collects impurities and the wastewater generated during impurity removal, making subsequent treatment of impurities and wastewater more convenient. However, the above patent still has the following shortcomings: relying solely on the convex filter screen to treat impurities in the water is not very effective; in addition, although the water can be filtered by the concave filter screen, the holes at the bottom of the convex filter screen are prone to clogging by impurities, and the clogged impurities are not easy to clean. Therefore, we propose a dirt remover for heat exchange stations. Utility Model Content

[0042] In this embodiment, the support frame 8 is used to support the square box 9 to ensure the stability of the square box 9 during insertion.

[0043] For details, please refer to Figures 2 to 5The inner wall of the U-shaped groove 6 is in contact with the side of the U-shaped filter plate 27, the outer diameter of the other end of the conical cylinder 2 is equal to the outer diameter of the bottom end of the U-shaped filter plate 27, and the outer side of the U-shaped filter plate 27 is in contact with the inner wall of the filter box 1.

[0044] In this embodiment, the stability of the U-shaped filter plate 27 installed in the inner cavity of the filter box 1 is ensured, while ensuring that the U-shaped filter plate 27 can completely filter the water.

[0045] Working principle: In use, water is first introduced into the inner cavity of the filter box 1 through the inlet pipe 14. The water is first filtered using the filter holes 16 on the U-shaped filter plate 27. The filtered impurities accumulate in the inner cavity of the U-shaped filter plate 27. The filtered water falls into the filter cotton 11 inside the square box 9 for a second filtration. The filtered water falls to the bottom of the inner cavity of the filter box 1 and is discharged through the drain pipe 15. Then, the servo motor 17 is started to drive the screw conveyor 18 to rotate. The screw conveyor 18 moves the impurities filtered from the inner cavity of the U-shaped filter plate 27, so that the impurities are introduced from the conical cylinder 2 and the L-shaped connecting pipe 3 into the collection cylinder 4 for further filtration. After cleaning the impurities, remove the first wing screw 21 from the first screw hole 19 and the first mounting hole 20 to release the U-shaped sealing plate 13, thereby pulling the U-shaped filter plate 27 out of the inner cavity of the filter box 1 so that the impurities blocking the filter holes 16 below the U-shaped filter plate 27 can be backwashed from the outside. After cleaning, reinsert the U-shaped filter plate 27 into the inner cavity of the filter box 1. Finally, remove the second wing screw 24 from the second screw hole 22 and the second mounting hole 23 to pull the square box 9 out of the inner cavity of the filter box 1 so that the filter cotton 11 inside the square box 9 can be pulled out and replaced. After replacement, reinsert the square box 9 into the inner cavity of the filter box 1.
