Examples

As shown in fig. 1 to 5, the present example provides a primary sand-water separation device in environmental remediation, comprising: separation chamber 1, outlet pipe 2, overflow filtering component etc..

In particular, the separation chamber 1 is intended to contain a mixture of sand and water to be separated, and is provided at one end with a feed pipe 11. The bottom of the separation chamber 1 is provided with an openable and closable closing door 12. Specifically, the bottom of the separation chamber 1 can be provided with a jack, the closing door 12 can be detachably inserted into the jack at the bottom of the separation chamber 1, and the closing door 12 is provided with a handle.

Specifically, the water outlet pipe 2 horizontally extends into the separation chamber 1 from the outside of the separation chamber 1, and a water inlet with a downward opening is formed in the bottom surface of the water outlet pipe 2 positioned in the separation chamber 1, and a blocking screen plate 21 is arranged at the water inlet for blocking sediment, as shown in fig. 5, the structure of the water outlet pipe 2 is schematically illustrated.

Specifically, the overflow filter assembly is arranged at the top of the separation cavity 1 and used for blocking and separating liquid overflowing from the top of the separation cavity 1 to the peripheral side.

As shown in FIGS. 1-4, the overflow filter assembly of the present example includes: annular filter screen 31, annular side keeps off 3, annular bottom plate 32, annular inner fender 33, drain pipe 35.

The annular filter screen 31 is disposed outwardly along the rim of the top opening of the separation chamber 1. The annular side baffle 3 is arranged along the outer periphery of the annular filter screen 31, and the top edge of the annular side baffle 3 is higher than the annular filter screen 31 by a preset distance. The annular bottom plate 32 is disposed below the annular filter screen 31 and has a predetermined distance from the annular filter screen 31, and the outer peripheral side thereof is connected to the annular side shield 3. The annular inner baffle 33 is located on the inner side of the annular side baffle 3, the bottom of the annular inner baffle 33 is connected to the inner peripheral side of the annular bottom plate 32, the annular inner baffle 33 and the annular side baffle 3 have a preset distance, the top of the annular inner baffle 33 is connected to the inner peripheral side of the annular filter screen 31, and the annular side baffle 3, the annular inner baffle 33 and the annular bottom plate 32 form an annular accommodating cavity 34. And the drain pipe 35 is connected with the annular side baffle 3 and communicated with the annular accommodating cavity 34.

When the separation device is used, liquid to be separated enters the separation cavity 1 from the feeding pipe 11, the height of the feeding pipe 11 is lower than that of the water outlet pipe 2, and the water outlet pipe 2 is lower than the top opening of the separation cavity 1. Along with the continuous feeding of the liquid, partial silt in the liquid is deposited towards the bottom of the separation cavity 1 under the action of gravity, and meanwhile, after the water outlet pipe 2 is submerged, the silt can be prevented from directly entering the water outlet pipe 2 due to the fact that the water outlet with a downward opening is formed in the bottom surface of the water outlet pipe 2 and the blocking screen plate 21 is arranged, and the silt cannot easily permeate towards the blocking screen plate 21 due to the fact that the silt is used per se; the water outlet pipe 2 conveys the primarily separated water to a post-treatment process. Meanwhile, along with the continuous feeding of liquid, the liquid level in the separation cavity 1 is continuously raised until the liquid level is higher than the top opening and overflows towards the peripheral side. At this time, the overflow filtering assembly separates and discharges the part of the overflow liquid, specifically: overflowing liquid is blocked by the annular side baffle 3 and limited in a certain area, under the action of the annular filter screen 31, part of water permeates and permeates through the annular filter screen 31 to enter the annular side baffle 3, the annular inner baffle 33 and the annular bottom plate 32 to form an annular containing cavity 34, and a small part of water overflows the upper layer and is blocked by the annular filter screen 31 along with silt overflowing outwards from the liquid under the action of water flow sloshing caused by continuous water inflow, so that the overflowing liquid cannot enter the annular containing cavity 34. The water separated into the annular accommodating cavity 34 is discharged to the next process through the water discharge pipe 35, so that the separation is realized by using another mode, and the separation efficiency is improved.

In the two-position separation and discharge mode of the embodiment, one of the two-position separation and discharge mode can utilize the gravity of silt, and the water outlet pipe 2 with the downward opening is matched with the screen plate 21 arranged at the opening, so that the silt is reduced from permeating into the screen plate 21 while the separation is achieved; and the other one is positioned at the overflow part on the peripheral side of the top opening of the separation cavity 1, so that the separated water yield can be improved, and meanwhile, the upper layer is positioned, so that less silt is carried over, and most of the silt is positioned at the lower layer.

The foregoing is only a preferred embodiment of the invention and is not intended to be the only or limiting embodiment of the invention. It should be understood by those skilled in the art that various changes and equivalent substitutions made herein may be made without departing from the scope of the invention as defined by the appended claims.
