Detailed ways

In order to make the purpose, technical solutions and advantages of the utility model clearer, the following will further describe the implementation of the utility model in conjunction with the accompanying drawings.

Please refer to Fig. 1-Fig. 2, a house sand filter drainage system 100 provided by the embodiment of the present utility model includes a sewer pipe 1, a first grit chamber 2, a second grit chamber, a drainage pipe 4 and a curved The pipe 5 and the downpipe 1 are extended vertically, and the opposite side walls of the first grit chamber 2 are respectively provided with a first water inlet 21 and a first water outlet 22, and the first water inlet 21 is connected to the first water outlet. The above-mentioned drain pipe 4 is connected; the second grit chamber 3 is arranged side by side with the first grit chamber 2, and the upper position of the opposite side walls of the second grit chamber 3 is respectively provided with a second water inlet 31 and The second water outlet 32, the first water outlet 22 communicates with the second water inlet 31 through a water pipe; the drain pipe 4 extends along the horizontal direction, and one end of the drain pipe 4 communicates with the second water outlet 32 , the other end of the drainage pipe 4 communicates with the underground drain 7; the first end of the elbow 5 extends horizontally, the second end of the elbow 5 extends vertically downward, and the first One end communicates with the drainage pipe 4 , the second end is located in the second grit chamber, and the outer wall of the second end is opposite to the second water inlet 31 .

By successively setting the first grit chamber 2 and the second grit chamber 3 between the sewer pipe 1 and the drain pipe 4, it is possible to prevent the sand from clogging the drain pipe 4, and the rainwater mixed with sand enters the first grit chamber through the sewer pipe 1. In the grit chamber 2, the sand particles sink to the bottom of the first grit chamber 2 under the action of gravity, and the rainwater enters the second grit chamber 3 through the first water outlet 22 through the water pipe. The sand that sinks can continue to sink in the second grit chamber 3, and the rainwater that does not have sand particles on the upper floor can flow away in the underground drain through the elbow 5 and the drainpipe 4. Here, the front end of the drain pipe 4 is provided with an elbow 5. On the one hand, the second end of the elbow 5 extends vertically downwards, and the outer wall of the second end is opposite to the second water inlet 31, which can prevent the second water inlet 31 from The water at the place directly enters the drainpipe 4 without precipitation, so as to avoid the clogging of the drainpipe 4;

Specifically, the lowermost end of the elbow 5 is not lower than one-third of the height of the second grit chamber 3 . The lowermost end of the elbow 5, i.e. the second end, is not lower than one-third of the height of the second grit chamber 3, which helps to prevent the rainwater with sand particles from entering at the bottom of the second grit chamber 3, thereby flowing into drainage In the pipe 4, the drain pipe 4 is further prevented from being clogged by deposited sand particles.

Further, as shown in FIG. 2 , a filter screen 6 is also included. The filter screen 6 includes a connected vertical section and a horizontal section. The filter screen 6 is L-shaped, and the horizontal section is arranged on the elbow 5, and connected with the side wall of the second grit chamber 3, the vertical section is arranged between the elbow 5 and the second water inlet 31, and connected with the second grit chamber The top wall of pool 3 is connected. Since firecrackers contain paper scraps in addition to sand grains, and there are sundries such as leaves on the roof, most of the sand grains will be deposited after falling by gravity in the first grit chamber 2, but the paper scraps or leaves will be Floating on the top, enter the second grit chamber through the first water outlet 22 and the second water inlet, by setting the L-shaped filter screen 6 under the elbow 5 and on the side, on the one hand, it can filter paper dust or leaves. Floating debris enters the drainpipe 4; on the other hand, it can prevent that when the rainwater is large, the sand particles in the rainwater have no time to settle, and when a large current enters the second grit chamber 3 from the second water inlet 31, the second The rainwater in the grit chamber 3 is relatively turbid. By setting the L-shaped filter 6, it can be ensured that the rainwater entering the drain pipe 4 is not mixed with large particles of sand or other sundries, thereby further preventing the drain pipe 4 from being blocked.

Specifically, the bottoms of the first grit chamber 2 and the second grit chamber 3 are provided with sand discharge outlets 33 , and sand discharge pipes are connected outside the sand discharge outlets 33 . By arranging a sand discharge port 33 at the bottom of the first grit chamber 2 and the second grit chamber 3 and connecting a sand discharge pipe, the sediment at the bottom can be cleaned regularly.

In one embodiment, as shown in FIG. 1 , the cross section of the sand discharge port 33 is Y-shaped, and the sand discharge port 33 includes a slope section and a vertical section, and the vertical section is located at the first sink. The bottom of the grit chamber 2 or the second grit chamber 3 , the slope section is used to connect the vertical section with the bottom wall of the first grit chamber 2 or the second grit chamber 3 . By setting the Y-shaped sand discharge port 33, the sand discharge port 33 is funnel-shaped, which helps sand particles to be discharged from the slope section, and the setting of the Y-shaped cross-section is more conducive to the accumulation of sediment. It is convenient for the sand discharge pipe in the vertical section to discharge the sediment intensively.

Similarly, in another embodiment, as shown in FIG. 2 , the bottom walls of the first grit chamber 2 and the second grit chamber 3 gradually move toward the sand outlet 33 from the two side walls. Tilt the setting down. The two ends are gradually inclined towards the direction of the sand discharge port 33, which helps the sediment to continue to settle to the bottom of the sand discharge under the action of the inclination of the bottom wall of the first grit chamber 2 or the second grit chamber 3 Port 33, thereby facilitating the concentration of sand particles to be discharged from the sand discharge port 33.

Further, the tops of the first grit chamber 2 and the second grit chamber 3 are provided with wellheads, and the wellheads are provided with well covers. By setting wellheads and covers on the top of the first grit chamber 2 and the second grit chamber 3, under normal circumstances, the manhole covers are in the state of sealing the wellheads. The first grit chamber 2 or the second grit chamber 3 is cleaned.

In this article, the orientation words such as front, rear, upper, and lower involved are defined by the parts in the drawings and the positions between the parts in the drawings, just for the clarity and convenience of expressing the technical solution. It should be understood that the use of the location words should not limit the scope of protection claimed in this application.
