Description

Technical Field

[0001] The utility model relates to a sand-water separator. Background Art

[0002] Chinese patent application number 202321168335.5 discloses a sand-water separator that can separate sand and gravel from water and collect the sand and gravel into a collection box.

[0003] The sand-water separator of the patent comprises: a water tank extending in the left-right direction, a water inlet trough provided at the left end of the top wall of the water tank, a guide plate provided inside the water tank, with the left end located just below the water inlet trough, a U-shaped trough provided inside the water tank, located on the right side of the guide plate, extending in the front-to-back direction, with a filtering hole provided at the bottom (the front and rear ends of the U-shaped trough are respectively sealed and fixedly connected to the front and rear side walls of the water tank), a fixing plate provided inside the water tank, located on the right side of the U-shaped trough, a shell penetrating the top wall of the water tank, with the bottom end extending to the bottom of the U-shaped trough, with a feed port provided at the bottom end and a discharge pipe externally connected to the top end, a shaftless screw built into the shell, a motor provided at the top end of the shell for driving the shaftless screw to rotate, a collecting box provided on the outer top wall of the water tank, just below the discharge pipe, a secondary filtering device connected to the right end of the water tank through the discharge pipe, a water pump provided on the discharge pipe, and a drain pipe externally connected to the secondary filtering device;

[0004] The guide plate includes: an inclined plate with its left end fixed to the left side wall of the water tank and its right end tilted downward (the front and rear ends of the inclined plate are respectively sealed and fixed to the front and rear side walls of the water tank); and a horizontal plate with its left end integrally connected to the right end of the inclined plate and its right end fixed to the left side of the top end of the U-shaped groove (the front and rear ends of the horizontal plate are respectively sealed and fixed to the front and rear side walls of the water tank);

[0005] The fixing plate is L-shaped and includes: a horizontal plate section whose left end is fixed to the right side of the top end of the U-shaped groove (the front and rear ends of the horizontal plate section are sealed and fixed to the front and rear side walls of the water tank respectively), and a vertical plate section whose bottom end is integrally connected to the right end of the horizontal plate body and the top end is fixed to the top wall of the water tank (the front and rear ends of the vertical plate section are sealed and fixed to the front and rear side walls of the water tank respectively).

[0006] The working principle of the patented sand-water separator includes:

[0007] The water containing sand and gravel is discharged into the water tank from the water inlet trough. The water flows through the inclined plate and the horizontal plate and then enters the U-shaped trough. Then the water falls from the filter holes at the bottom of the U-shaped trough to the bottom of the water tank. The sand and gravel in the water are intercepted by the U-shaped trough.

[0008] The water pump draws the water from the bottom of the water tank to the secondary filter device through the outlet pipe for further treatment. The water treated by the secondary filter device is discharged through the drain pipe for reuse.

[0009] The motor drives the shaftless screw to rotate, and the sand and gravel at the bottom of the U-shaped trough enters the shell from the feed port at the bottom of the shell. The sand and gravel entering the shell are lifted to the discharge pipe by the shaftless screw and finally fall into the collection box along the discharge pipe.

[0010] Although the sand-water separator of this patent can intercept sand and gravel in water through the U-shaped groove with filter holes at the bottom; the filter holes at the bottom of the U-shaped groove are easily clogged by the intercepted sand and gravel, which will affect the normal performance of the filter holes of the U-shaped groove, and further affect the performance of the entire sand-water separator.
