DETAILED DESCRIPTION

[0020] Reference Figures 1 to 4 As shown, the utility model provides a rural drinking water treatment water quality filtering and purification device, comprising: a purification box 1 and a water distribution component 2, wherein the interior of the purification box 1 is provided with a clean water chamber 11, a filter chamber 12 and a water accumulation chamber 13 from top to bottom, and a partition plate 15 is provided between the clean water chamber 11 and the filter chamber 12, and a quartz sand filter material 123 is provided inside the filter chamber 12, a sand filter tank water cap 122 is provided at the lower side of the quartz sand filter material 123, and a water cap plate 121 is provided at the lower side of the sand filter tank water cap 122, and the water distribution component 20 is provided with a water distribution component 21 ... The water assembly 2 is arranged on the inner side of the filter chamber 12 and is connected to the lower end of the partition 15, and the water distribution assembly 2 includes a water distribution tray 23, and the lower end of the water distribution tray 23 is connected to a stirring rod 233, the outer wall of the water accumulation chamber 13 is connected to a water outlet pipe 17, and the upper end of the water outlet pipe 17 is connected to the clean water chamber 11, a one-way valve 18 is provided at the connection between the water outlet pipe 17 and the water accumulation chamber 13, and a water pump 19 is installed in the delivery pipeline of the water outlet pipe 17, and the water pump 19 is fixed to the outer wall of the purification box 1.

[0021] In this embodiment, the purification box 1, the inner and outer structures and the water distribution assembly 2 constitute the main structure of the rural drinking water treatment water quality filtering and purification device involved in this application.

[0022] Specifically, the quartz sand filter material 123, the sand filter tank water cap 122 and the water cap plate 121 are consistent with the same structure involved in the comparative document in the background technology, wherein a porous structure is opened inside the water cap plate 121, and the water cap plate 121 is fixed to the inner wall of the filter chamber 12.

[0023] As a preferred embodiment, by arranging the water outlet pipe 17 on the outside of the purification box 1, the purified water is pumped into the clean water chamber 11 by the water pump 19. When backwashing, the water pump 19 can be turned off and the water outlet pipe 17 is closed by the one-way valve 18, so that the water storage and backwashing operations of the water chamber 13 can be realized.

[0024] like Figure 1 As shown, the outer wall of the clean water chamber 11 is provided with a water outlet 14, and the outer side of the clean water chamber 11 is connected to a siphon backwashing device through a pipe, the inner wall of the filter chamber 12 is plugged with a water inlet pipe 16, and the inner end of the water inlet pipe 16 is bent downward, and the water inlet pipe 16 is located on the upper side of the water distribution tray 23.

[0025] As a preferred embodiment, a water inlet pipe 16 is provided to facilitate the introduction of the precipitated water into the water storage tank 231 of the water distribution tray 23, and the water levels of the inlet water and the water storage tank 231 are kept consistent during the process to avoid the water storage tank 231 being full of water. At the same time, when the water distribution tray 23 is receiving water, the lower end of the water inlet pipe 16 is located on the inner side of the water storage tank 231 to prevent splashing when the water flows downward.

[0026] like Figure 2 and Figure 4 As shown, a water storage tank 231 is provided on the upper side of the water distribution tray 23, and a driving shaft 221 is connected to the center of the water storage tank 231, and the upper end of the driving shaft 221 is connected to a driving box 22, and the upper end of the driving box 22 is connected to an electric push rod 21, and the electric push rod 21 is vertically installed at the lower end of the partition 15, and a drainage hole 232 connected to the water storage tank 231 is provided on the outer circumferential wall of the water distribution tray 23, and a leakage hole 234 is provided at the bottom of the water distribution tray 23, and the upper end of the stirring rod 233 is fixed in the leakage hole 234 by a connecting rod 235, and the inner diameter of the leakage hole 234 is larger than the outer diameter of the stirring rod 233.

[0027] Specifically, a tip is provided at the bottom of the stirring rod 233 to facilitate insertion of the quartz sand filter material 123. At the same time, through the leakage hole 234, after stirring and loosening, after the water inlet pipe 16 is opened, the water is diverted downward through the leakage hole 234 to wash away the sand contaminated on the outer wall of the stirring rod 233.

[0028] As a preferred embodiment, by setting the leakage hole 234 and the drainage hole 232, water is dispersed on the outside and bottom of the water distribution tray 23, thereby facilitating the uniform diffusion of the water flow and uniformly falling into the quartz sand filter material 123, achieving uniform filtration and sufficient filtration effect.

[0029] When in use, open the water inlet pipe, and the water flows into the water distribution tray through the water inlet pipe, and then flows out through the leakage hole and the drainage hole to fall on the quartz sand filter material, thereby achieving the filtering effect. Then, the clean water in the water accumulation chamber is pumped into the clean water chamber through the water pump and the outlet pipe, and then discharged through the water outlet. When cleaning is required, close the water inlet pipe, and then start the electric push rod to push the water distribution tray downward until the stirring rod is inserted into the quartz sand filter material. Then, start the motor in the drive box, so that the water distribution tray and the stirring rod are driven to rotate at the same time through the drive shaft, thereby stirring the compacted quartz sand filter material to restore it to a soft state, thereby ensuring the water flow efficiency and improving the filtration and purification efficiency.

[0030] The rural drinking water treatment water quality filtering and purification device of the utility model can effectively solve the problem that the quartz sand filter material of the existing rural drinking water treatment water quality filtering and purification device is easy to harden after long-term use, resulting in reduced filtration efficiency, and there is also a problem of deviation in the filtration effect of some water flows. On the basis of the existing rural drinking water treatment water quality filtering and purification device technology, an anti-caking device for the quartz sand filter material is added, thereby ensuring the filtration efficiency and the filtration effect.
