Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

See fig. 1-2.

The invention provides a novel spiral sand washer, which comprises: a sand washing tank 1 for containing sand and water;

the sand washing device comprises a rotating shaft 2 and a propeller blade 3, wherein the propeller blade 3 is fixedly arranged on the rotating shaft 2, the rotating shaft 2 provided with the propeller blade 3 is positioned in a sand washing tank 1, and a bearing box 4 is arranged on the inner wall of the lower part of the sand washing tank 1;

the inner wall of the bearing box 4 and the outer ring of the bearing 5 are fixedly arranged, and the inner ring of the bearing 5 is fixed with the periphery of the rotating shaft 2 penetrating through the bearing box 4;

a sealing ring 6 for sealing the inner ring and the outer ring of the bearing 5 and the gap between the rotating shaft 2 and the bearing 5 is fixed on the inner wall of the bearing box 4;

a horn-shaped sand blocking piece 7 is fixed on the rotating shaft 2, and the inclination direction of a horn mouth is opposite to that of the bearing 5;

the bottom surface in the bearing box 4 is an inclined surface which is inclined downwards far away from the bearing 5, and the inclined surface is provided with a sand cleaning pipe 8 communicated with the inside of the bearing box 4;

the other end of the sand cleaning pipe 8 penetrates through the outside of the sand washing tank 1.

The radial width of the sand blocking piece 7 is larger than that of the bearing 5, and even if the sealing ring 6 is damaged, the sand blocking piece 7 plays a role in protecting the bearing 5.

The periphery of the sand blocking piece 7 is in tangential contact with the inner surface of the top of the bearing box 4 all the time during rotation, so that sand grains are prevented from entering the bearing 5 when entering from a gap between the bearing 5 and the bearing box 4.

A valve 9 is arranged at the end of the external sand cleaning pipe 8, the valve 9 is closed to slowly accumulate a sand-water mixture on the inclined surface at the bottom inside the bearing box 4, and then intermittent high-pressure air is flushed by opening the valve 9 to clean the inside of the bearing box 4 and the sand blocking piece 7 by water in the sand-water mixture; the valve 9 is normally open and discharges the sand-water mixture entering from the gap between the bearing 5 and the bearing housing 4.

The motor is characterized by further comprising a motor 10 and a rack 11, wherein the fixed end of the motor 10 is fixed on the rack 11 to be supported, and the rotating output end of the motor 10 is fixedly connected with the rotating shaft 2 through welding or a coupler or a key.

The bottom surface of the sand washing tank 1 is fixed on the frame 11 and is inclined, so that the bearing 5 is positioned at the bottom.
