Of course, the drainage surface 109 may not be the inner wall surface of the shell 101, for example, in another embodiment, the drainage mechanism further includes a drainage component, the drainage component is fixedly installed in the inner sedimentation chamber 102, the drainage component includes a drainage plate 108 fixedly installed on one side of the drainage plate 107, as shown in fig. 9, the lower end of the drainage plate 108 may extend to the bottom of the shell 101, in this case, the drainage surface 109 is the outer wall surface on one side of the drainage plate 108, the gap 110 is the gap 110 between the drainage plate 107 and the drainage plate 108, the drainage plate 108 may be installed in the inner sedimentation chamber 102 vertically or obliquely, and likewise, in actual operation, sewage may flow to the drainage plate 108 under the guiding action of the drainage plate 107 and flow downwards along the outer wall of the drainage plate 108 without impacting on the sand grains sedimented below, but also can generate a wall attachment effect, and is beneficial to the quick separation of sand and water.

Since the sewage entering the inner settling chamber 102 from the water inlet 103 generally has a certain water pressure, under the action of water pressure, the sewage easily rushes out of the guide plate 107 along the direction of the water inlet 103, so that the sewage can flow along the guide part and change the direction, in a further embodiment, the flow guiding mechanism further comprises a blocking member, the blocking member comprising a fixedly mounted baffle 111, the baffle 111 is located at one end of the baffle 107, as shown in figures 3 and 4, the water inlet 103 and the baffle 111 are respectively positioned at two ends of the guide plate 107, the baffle 111 mainly plays a role of water retaining and is matched with the guide plate 107, the sewage flowing in from the water inlet 103 at one end of the guide plate 107 can be prevented from directly flowing out from the other end of the guide plate 107, so that the sewage can change the flow direction under the combined action of the guide plate 107 and the baffle 111 and flow to the guide surface 109.

The baffle 111 may be disposed in various embodiments, as an example, the baffle 111 may be directly connected to the flow guide plate 107, for example, the baffle 111 may be disposed at an end of the flow guide plate 107 away from the water inlet 103, and the baffle 111 and the flow guide plate 107 may be an integral structure; as another example, the baffle 111 may be fixed to a bracket 112, and the bracket 112 may be fixedly installed on the housing 101, such that the baffle 111 is located at one end of the flow guide plate 107, as shown in fig. 3 and 7, and not only can be matched with the flow guide plate 107 to play a role of retaining water, but also can play a role of separating in the inner settling chamber 102, such that the flow guide surface 109, the sidewall of the housing 101 configured with the water inlet 103, the flow guide plate 107, and the baffle 111 can jointly define a flow guide chamber for guiding sewage, and thus, the sewage in the inner settling chamber 102 can be effectively prevented from fluctuating by a large margin.

In a more perfect scheme, the side wall of the casing 101 is further configured with an overflow port 105 communicated with the inner settling chamber 102, as shown in fig. 1-3, and the overflow port 105 and the water inlet 103 are respectively located at two sides of the baffle 111, so that the baffle 111 can play a role of separation, the water inlet fluctuation at one side of the water inlet 103 is prevented from influencing the drainage at the overflow port 105 at the other side, and sand grains, especially sand grains with small grain diameter, can be effectively prevented from flowing out of the overflow port 105.
