Description

Technical Field

[0001] This utility model belongs to the field of boiler water filtration technology, specifically relating to a multi-media filter for boiler water treatment. Background Technology

[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water, or organic heat carriers with a certain amount of thermal energy. Boiler water is liquid water within the boiler or related pipes, pumps, and other equipment, used to evaporate into steam. It can be used as raw water for the boiler, treated boiler feedwater, steam condensate returned to the boiler, or boiler blowdown. Before boiler water treatment, processes such as sedimentation, condensation, separation, and filtration are used to pre-treat the boiler water to remove suspended solids, organic matter, colloids, and other impurities, meeting the requirements of chemical water treatment processes. Residual impurities accumulate on the boiler, forming scale, which increases boiler water consumption and reduces water production. This includes water that has been filtered through filter media, where impurities are captured and removed.

[0003] In existing technologies, large particles or impurities in raw water are filtered out using a filter screen to ensure that no large particles or impurities enter the boiler and cause sediment buildup after the boiler evaporates the raw water. However, existing filters accumulate a large amount of impurities on the surface of the filter screen after filtration, requiring regular cleaning of the filter screen over a long period of use. It is not possible to effectively remove and clean the filter screen. Therefore, there is an urgent need to design a multi-media filter for boiler water treatment to address these issues.

[0014] This utility model discloses a multi-media filter for boiler water treatment. Through a multi-layered filtration mechanism, water enters the filter box through the inlet assembly and falls onto two sets of first-level mesh filter plates and sand / gravel filter plates within the filter screen box. Activating the electric telescopic rod moves the lifting platform and filter screen box up and down within the groove. After the water passes through the sand / gravel filter plates, it falls onto two sets of second-level mesh filter plates and activated carbon filter plates for multi-stage filtration. After a period of use, the filter screen box and second-level mesh filter plates are cleaned using a second rotating rod, a moving belt, and a cleaning brush.

[0026] In this embodiment: the multi-layer filtration mechanism 3 includes a filter box 301 fixedly disposed on one side of the agitation mechanism 2. A water inlet assembly is disposed above the filter box 301. An end plate 302 is disposed on the front side of the filter box 301. A baffle 303 is disposed on the front side of the end plate 302. A groove 304 is vertically fixedly installed on the inner side wall of the filter box 301. A lifting platform 3041 is movably installed in the groove 304. An electric telescopic rod 305 is installed on the lifting platform 3041. A filter screen box 306 is fixedly installed on the lifting platform 3041. Two sets of first-stage filters are horizontally and parallelly movably installed in the filter screen box 306. A filter screen 307 is provided, with sand and gravel filter plates 3071 arranged parallel to each other between two sets of first-grid filter plates 307. Two sets of second-grid filter plates 310 are horizontally and movably installed below the filter screen box 306, with activated carbon filter plates 311 arranged parallel to each other between the two sets of second-grid filter plates 310. A water outlet assembly is installed on the filter box 301. A second rotating rod 308 is longitudinally and parallel to the second-grid filter plates 310 between the filter box 306 and the second-grid filter plates 310. A moving belt 3081 is provided on the outer surface of the second rotating rod 308, and cleaning brushes 309 are equidistantly and parallelly installed on the outer surface of the moving belt 3081. The cleaning brushes 309 are made of soft material. The water inlet assembly includes a second water inlet pipe 300 located above the filter box 301, with a spray nozzle 3001 installed on the second water inlet pipe 300. The water outlet assembly includes a water outlet pipe 312 mounted on the filter housing 301. A second pump body 3121 is installed between the water outlet pipe 312 and the filter housing 301. A power source is installed at one end of the second rotating rod 308. Sand and gravel filter plates 3071 and activated carbon filter plates 311 are arranged vertically. Larger particles and suspended impurities in the water are first filtered out by two sets of first grid filter plates 307 and sand and gravel filter plates 3071. Then, fine particles, bacteria, microorganisms, and gases in the water undergo secondary adsorption and filtration by two sets of second grid filter plates 310 and activated carbon filter plates 311, resulting in clean boiler water. This clean water, when introduced into the boiler, greatly prevents the formation of scale and slag inside the boiler, effectively improving the boiler's working efficiency and performance. The guide plate can evenly distribute the incoming water, fully utilizing filtration resources and enhancing the filtration effect. An observation hole 3031 is provided on the end plate 302. A sealing element is provided between the end plate 302 and the baffle 303. The end plate 302 and the baffle 303 are rotatably connected, which facilitates the disassembly of the sand and gravel filter plate 3071 and the activated carbon filter plate 311, making it easy to clean and replace them regularly to ensure the multi-media filtration water purification effect.

[0027] Working Principle: During operation, boiler water is first introduced into the cylinder 202 through the first water inlet pipe 203. The power motor 204 is started, driving the first rotating rod 205 and the agitator blade 206 to rotate. Simultaneously, a water cleaning agent is added to the rotating water through the dispensing pipe 207. After stirring, the water flows into the horizontal pipe 208 through the connecting pipe and one-way valve, undergoing initial filtration through the first filter screen 209. The first pump 211 is then started, spraying the water into the filter box 301 through the second water inlet pipe 300 and the spray nozzle 3001. The electric telescopic rod 305 is activated, raising and lowering the filter screen box 306. The water undergoes secondary filtration through the first mesh filter plate 307 and the sand and gravel filter plate 3071. After filtration, the water passes through the second mesh filter plate 310 and the activated carbon filter plate 311 for further filtration. The three-stage filtration process allows the water in the filter housing 301 to undergo multiple multi-media filtrations. The filtered water is then discharged through the second pump body 3121 and the outlet pipe 312, facilitating boiler operation. After a period of use, the electric telescopic rod 305 is activated to lower the filter screen box 306. The power source is then activated to rotate the second rotating rod 308 and the moving belt 3081, simultaneously driving the cleaning brush 309 to rotate and clean the bottom of the filter screen box 306 and the upper surface of the second mesh filter plate 310. When there are too many impurities on the outer surface of the sand and gravel filter plate 3071 and the activated carbon filter plate 311, they are observed through the observation hole 3031. After the water in the filter housing 301 is discharged, the baffle 303 is opened to pull out the sand and gravel filter plate 3071 and the activated carbon filter plate 311 for cleaning.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
