Description

Technical Field

[0001] The utility model relates to a filtering device, in particular to a micron-level chilled water filtering device. Background Art

[0002] After the water in the circulating pipeline absorbs the cold quantity of the refrigerant from the evaporator of the central air-conditioning water-cooled unit, the water temperature becomes lower and becomes chilled water, and the temperature of the chilled water is about 7°C. The chilled water is then sent to various air-conditioning terminal devices in the building, such as fan coil units. When the fan blows air against the fan coil unit, cold air can be blown out. The chilled water heats up to about 12°C after absorbing heat and is sent back to the evaporator to circulate and release and absorb heat.

The opening edge of the cylinder body 32 is provided with a lower ear 323. The edge contour of the lower ear 323 corresponds to the positioning notch 3161. Both the upper ear 316 and the upper ear 316 are provided with two insertion holes for the insertion pin 34 to be inserted.

[0035] Specifically, the number of the filter cartridges 3 is eight, and the filter cartridges 3 are arranged along the length direction of the liquid inlet main pipe 1.

[0036] Specifically, the liquid inlet main pipe 1 is formed by alternately connecting a pipe section 101 and a joint 12. The joint 12 is in a T shape, thus forming an interface section 121. A screw sleeve 122 is rotatably sleeved on the interface section 121. The liquid inlet end of the liquid inlet branch pipe 11 is threadedly connected to the screw sleeve 122, and the liquid inlet end of the liquid inlet branch pipe 11 is press-fitted through the interface section 121.

[0037] Specifically, the liquid outlet main pipe 2 is formed by alternately connecting a pipe section 101 and a joint 12. The joint 12 is in a T shape, thus forming an interface section 121. A screw sleeve 122 is rotatably sleeved on the interface section 121.

The liquid outlet elbow 22 is connected with a liquid outlet connecting pipe 23, and the liquid outlet connecting pipe 23 has the same orientation as the liquid inlet elbow 13.

[0039] Specifically, several twisting flanges 324 are provided at the outer wall edge of the opening of the cylinder body 32, and the twisting flanges 324 are arranged vertically.

[0040] Specifically, the cylinder body 32 is made of transparent plastic material.

[0041] Specifically, the filter element is a micron-level filter element.

[0042] The working principle of the micron-level chilled water filtering device of the present utility model is as follows:

[0043] See Figure 1 , the micron-level chilled water filtering device of the present utility model is arranged between two pipelines of the chilled water circulation system, so that the water in one pipeline flows into the liquid inlet main pipe 1, and then flows into each filter cylinder 3 through a plurality of liquid inlet branch pipes 11.

[0044] See Figure 4 , the liquid flows into the cylinder body 32 through the liquid inlet 311. The filter element (not shown in the figure) is in a cylindrical shape. The upper end of the filter element is sleeved on the upper inner edge 313, and the outer wall of the upper end of the filter element abuts against the inner wall of the upper outer edge 314. The lower end of the filter element is sleeved on the lower inner edge 321, and the outer wall of the lower end of the filter element abuts against the inner wall of the lower outer edge 322. As the cylinder body 32 is filled with the liquid, the liquid flows to the liquid outlet branch pipe 21 through the liquid outlet channel 315, and then converges to the liquid outlet main pipe 2 and flows to another pipeline (see Figure 1 ). The liquid flowing through the cylinder body 32 is filtered by the filter element, so that impurities such as large particles, sediment, rust, red worms, and heavy metals in the circulating chilled water can be removed.

[0045] The cylinder body 32 is made of transparent plastic material, which can timely observe the usage condition of the PP cotton filter element. If the filter element needs to be replaced, use the Figure 6 shown handle 4. Put the ring of the handle 4 outside the cylinder body 32, so that each convex block 41 abuts against the corresponding twisting flange 324, and then rotate the handle 4 to screw out the cylinder body 32. After replacing the filter element, use the handle 4 to screw the cylinder body 32 back again. When the lower ear part 323 is screwed to cooperate with the positioning notch 3161, the cylinder body 32 is screwed to the appropriate position. At this time, there is a slight gap between the top end of the filter element and the bottom side of the liquid outlet channel 315, meeting the installation requirements.

[0046] Refer to Figure 7 , after wrapping the outer end of the liquid inlet branch pipe 11 with sealing adhesive tape, align the outer end with the interface section 121 of the joint 12, and then, rotate the screw sleeve 122 to form a threaded connection between the screw sleeve 122 and the external thread of the liquid inlet branch pipe 11. The rotation of the screw sleeve 122 drives the liquid inlet branch pipe 11 to insert into the interface section 121 (as shown in Figure 7 ), so as to realize the connection between the liquid inlet branch pipe 11 and the joint 12. The connection between the liquid outlet branch pipe 21 and the joint 12 is the same by the same token.

[0047] The utility model adopts a parallel connection mode of eight filter cartridges 3, which can improve the liquid flow rate per unit time and the filtration efficiency. The micron filtration device of the utility model can filter the circulating chilled water, filter out impurities such as large particles, sediment, rust, red worms, heavy metals, etc., and avoid the precipitation of impurities on the inner wall of the pipeline, affecting the heat exchange effect of air conditioning equipment.

Although the utility model has been disclosed above with the preferred embodiments, it is not intended to limit the utility model. Any person skilled in the art can make some changes or modifications into equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the utility model. However, as long as it does not depart from the content of the technical solution of the utility model, any brief modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the utility model still fall within the scope of the technical solution of the utility model.
