[0002] Filters are an indispensable device in pipelines transporting media. They are usually installed at the inlet end of pressure reducing valves, pressure relief valves, and level control valves to facilitate the filtering of other equipment. Filters consist of a cylinder, stainless steel filter screen, sewage discharge section, transmission device, and electrical control section. After the water to be treated passes through the filter screen cylinder, impurities are blocked. When cleaning is required, simply remove the detachable filter screen cylinder, clean it, and reinstall it. Therefore, it is extremely convenient to use and maintain.

[0003] In the process of realizing this utility model, the inventors discovered the following problems with the prior art:

[0004] Traditional multi-media filters use a dome-shaped perforated plate with pebbles for filtration and water distribution. This structure has the disadvantages of high filtration resistance, resulting in low flow velocity and uneven water distribution, which leads to low filtration accuracy. Utility Model Content

[0005] The purpose of this utility model is to provide a continuous multi-media filter to solve the problems mentioned in the background art, where traditional multi-media filters use a domed porous plate with pebbles for filtration and water distribution. This structure suffers from high filtration resistance, resulting in low flow velocity and uneven water distribution. To achieve the above objective, this utility model provides the following technical solution: a continuous multi-media filter, including a housing, the outer wall of which is hinged to a cover plate;

[0006] An exhaust pipe is screwed onto the top of the housing. A feed inlet is welded to one side of the housing, and a discharge outlet is welded to the other side.

A backwash inlet is welded onto the top of the perforated plate. The output shaft of a cylinder is mounted on the bottom of the perforated plate via a pin. A drain outlet extends through the bottom plate of the housing. An air inlet is installed above the drain outlet via a flange. A backwash inlet and a liquid outlet are located above the air inlet. A liquid outlet is located behind the backwash inlet. A water cap is welded onto the top of the perforated plate.

[0007] A first sealing strip is glued to the top of the cover plate, and a second sealing strip is glued to the bottom of the cover plate. A first support plate is welded to one side of the cover plate, and a threaded rod is threaded into the inside of the first support plate. A second support plate is threaded into one side of the threaded rod.

Stone 112, a backwash inlet 107 is welded on the top of the perforated plate 114, and the output shaft of the cylinder 109 is installed below the perforated plate 114 via a shaft pin. The bottom plate of the housing 1 has a drain outlet 111 through it. An air inlet 110 is installed above the drain outlet 111 via a flange. A backwash inlet 107 and a liquid outlet 106 are respectively provided above the air inlet 110. A liquid outlet 106 is provided behind the backwash inlet 107. A water cap 108 is welded on the top of the perforated plate 114.

[0025] A first sealing strip 201 is glued to the top of the cover plate 2, a second sealing strip 202 is glued to the bottom of the cover plate 2, a first support plate 203 is welded to one side of the cover plate 2, a threaded rod 204 is threaded to the inside of the first support plate 203, and a second support plate 205 is threaded to one side of the threaded rod 204.

[0026] In this embodiment, as Figure 3 As shown, the backwash outlet 104 and the liquid inlet 102 are connected by a straight pipe with a feed inlet 105 and a liquid inlet 102 at each end.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the housing 1 is integrally connected to the feed inlet 105, and the housing 1 is integrally connected to the discharge port 103.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the quartz 112 and filter layer 113 inside the shell 1 are arranged vertically, and the filter layer 113 is composed of glass fiber, polyester fiber, polypropylene fiber and activated carbon.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the perforated plate 114 forms a vertical sliding structure through the cylinder 109, and the other side of the perforated plate 114 is connected to the housing 1 through a hinge.

[0030] In this embodiment, as Figure 4 As shown, several water caps 108 are evenly distributed above the perforated plate 114.

[0031] In this embodiment, as Figure 1 , Figure 2 and Figure 5 As shown, the external structural dimensions of the cover plate 2 are consistent with the external structural dimensions of the first sealing strip 201 and the second sealing strip 202, and the external threads of the threaded rod 204 are sequentially connected to the first support plate 203 and the second support plate 205.

[0032] The usage method and advantages of this utility model: The continuous multi-media filter operates as follows:

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the water to be treated first enters the housing 1 through the liquid inlet 102. After entering, the water passes through the quartz stone 112 and the filter layer 113 from top to bottom. The quartz stone 112 serves as the initial filter and supports the filter layer 113. The filter layer 113 is composed of glass fiber, polyester fiber, polypropylene fiber, and activated carbon, which can further intercept suspended solids, colloids, and other mechanical impurities in the water, thus purifying the water. The filtered water reaches the porous plate 114, passes through the water cap 108, and flows out from the liquid outlet 106, completing the initial purification. As filtration continues, the filter layer 113 and the quartz stone 112 will trap a large amount of impurities, requiring further treatment. Backwashing and regeneration are required. At this time, water enters through the backwash inlet 107, and the water flow direction is opposite to that during filtration. The water flows from bottom to top, rinsing the filter layer 113 and quartz stone 112, loosening and removing trapped impurities. During the backwashing process, the cylinder 109 works, driving the perforated plate 114 to slide vertically, which helps to better rinse and loosen the filter media. The backwash wastewater is discharged through the backwash outlet 104. After the backwashing is completed, the drain outlet 111 is opened to discharge the remaining backwash wastewater. At the same time, the air inlet 110 can be used to introduce air to help dry or further clean the internal residual moisture and impurities, ensuring that the inside of the filter is clean and ready for the next filtration.

[0034] The threaded screw 204 moves out of the first support plate 203 and the second support plate 205 in sequence to facilitate opening the cover plate 2. The first sealing strip 201 and the second sealing strip 202 play a sealing role. They are connected to the shaft pin below the perforated plate 114 through the output shaft. When working, the cylinder 109 can output power to drive the perforated plate 114 to move around its hinge connection point with the housing 1, and drive the perforated plate 114 to slide vertically, so that the quartz stone 112 and the filter layer 113 can be poured out for easy replacement.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
