Detailed implementation manners
[0026] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the drawings and embodiments.
[0027] In one embodiment, as Figures 1 - 5 shown, a vertical shallow sand filter that is easy to install includes a filter main body 100, a water inlet, a water outlet 600, and a sand filter layer 700. The top end of the filter main body 100 is provided with a water inlet, the lower end of the filter main body 100 is provided with a support column 101, the bottom end of the filter main body 100 is provided with a water outlet 600, a sand filter layer 700 is arranged inside the filter main body 100, a water filter cap 800 is arranged at the lower end of the sand filter layer 700, the water inlet is composed of a connecting pipe 200 and a lifting pipe 300, the lower end of the lifting pipe 300 is connected to the filter main body 100, and the connecting pipe 200 is fixed to the upper end of the lifting pipe 300. During use, an external water source is connected to the connecting pipe 200. When connecting, the appropriate docking height is adjusted through the lifting pipe 300. The water source enters the main body of the filter main body 100 through the water inlet, is filtered successively through the sand filter layer 700 and the water filter cap 800, and then flows out from the water outlet 600.
[0028] In one embodiment, as Figures 1 - 3 shown, the connecting pipe 200 is horizontally fixed to the upper end of the lifting pipe 300. One end of the connecting pipe 200 is closed, and the other end is provided with a flange. When connecting to an external water source, first adjust the connecting pipe 200 to an appropriate height through the lifting pipe 300, and then connect the connecting pipe 200 to the external water source through the flange.
[0029] In one embodiment, as Figure 4 shown, the lifting pipe 300 includes a movable pipe 301, a fixed seat 305, and a driving mechanism. The lower end of the fixed seat 305 is fixed to the filter main body 100, the movable pipe 301 is arranged inside the fixed seat 305, and the driving mechanism is fixed to the fixed seat 305. Under the action of the driving mechanism, the movable pipe 301 can move up and down inside the fixed seat 305.
[0030] In one embodiment, as Figure 4 shown, a rack 302 is provided outside the movable pipe 301. The driving mechanism includes a gear 303 and a motor 304. The gear 303 is in meshing connection with the rack 302. The motor 304 is fixed outside the fixed seat 305, and the gear 303 is fixed to the output end of the motor 304. When in use, the motor 304 drives the gear 303 to rotate, so that the rack 302 drives the movable pipe 301 to move up and down.
[0031] In one embodiment, as Figure 1 and Figure 2 shown, a sand adding port 400 is provided on one side of the filter body 100, and a sand discharging port 500 is provided on the other side of the filter body 100. The sand adding port 400 is arranged above the sand filter layer 700, and the sand discharging port 500 is arranged at the lower end of the sand filter layer 700. When in use, quartz sand serving as the sand filter layer 700 is added through the sand adding port 400. When the sand filter layer 700 needs to be replaced after being used for a period of time, the quartz sand of the sand filter layer 700 is discharged from the sand discharging port 500, and then new quartz sand is added through the sand adding port 400.
[0032] In one embodiment, as Figure 1 and Figure 2 shown, a first sealing cover 401 is provided outside the sand adding port 400, and a second sealing cover 501 is provided outside the sand discharging port 500.
[0033] In one embodiment, as Figure 3 shown, a bearing plate 701 is provided at the bottom layer of the sand filter layer 700. The bearing plate 701 is inclined and arranged inside the filter body 100. Water passing holes are evenly distributed on the bearing plate 701. During filtration, the water source is filtered by the sand filter layer 700 and then flows downward through the water passing holes on the bearing plate 701.
[0034] In one embodiment, as Figure 3 shown, a fixing plate 801 is provided at the lower end of the water filter cap 800. The fixing plate 801 is fixed inside the filter body 100. The water filter caps 800 are evenly arranged on the fixing plate 801. The water source filtered by the sand filter layer 700 flows onto the fixing plate 801, and then is filtered again through the water filter caps 800 and finally flows out through the water outlet 600.
[0035] In one embodiment, as Figure 5 shown, in order to prevent the water source at the water inlet from directly impacting the sand filter layer 700, a water distribution pipe 900 is connected to the lower end of the lifting pipe 300. Water outlet holes are evenly distributed at the lower end of the water distribution pipe 900, and the water source is dispersed and falls through the water distribution pipe 900.
[0036] The above embodiments disclose a vertical shallow sand filter that is easy to install. When in use, first adjust the connecting pipe 200 to an appropriate height through the lifting pipe 300 so that the connecting pipe 200 is connected to an external water source. The water source enters the filter body 100 through the connecting pipe 200 and the lifting pipe 300, first passes through the sand filter layer 700 for filtration, then flows downward to the water filter cap 800 for further filtration, and finally flows out through the water outlet 600. When the filter has been used for a period of time, dirt will accumulate on the sand filter layer 700, affecting the filtration effect. At this time, the sand filter layer 700 needs to be replaced. When replacing, open the sand discharge port 500, discharge the quartz sand of the sand filter layer 700 from the sand discharge port 500, and then add new quartz sand from the sand filling port 400.
[0037] As described above, the above are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
