Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-5, a sand washer filter screen of a sand blocking prevention net is arranged inside a sand washing impeller 2 of a sand washer 1, the working principle of the sand washer 1 is that a power device drives the sand washing impeller 2 to continuously and slowly rotate, stone enters a washing tank of the sand washer 1 from a feeding tank, rolls under the driving of the sand washing impeller 2, and a shovel tank 3 stirs a sand-water mixture in the tank of the sand washer 1, and enables sand and stone to turn over and grind each other, so that sand and stone are cleaned.

The sand washer 1 filter screen body is designed into an integrated into one piece structure of bending, sand washer 1 filter screen body has upper retaining wall 8 and lower retaining wall 9 and connects the bight 7 between upper retaining wall 8 and lower retaining wall 9, the end of upper retaining wall 8 and lower retaining wall 9 is link 6, be equipped with the screw on the link 6, sand washer 1 filter screen body is bent the shaping after punching, link 6 passes through the screw and can dismantle the connection at every shovel inslot 3 of sand washing impeller 2, be equipped with a plurality of through-holes 5 on the sand washer 1 filter screen body, through-hole 5 is round platform form, from through-hole 5 top along bottom size convergent, wash through the washing power of sand washing impeller 2 rotation through-hole 5, the automatic clear the jam in the through-hole 5.

The length of the lower retaining wall 9 is greater than that of the upper retaining wall 8, the upper retaining wall 8 and the lower retaining wall 9 are respectively and tightly attached to the upper wall and the lower wall of the shovel groove, the bending part 7 is U-shaped, in the embodiment, the design included angle of the upper retaining wall 8 and the lower retaining wall 9 for attaching to the shovel groove is 18 degrees, the radius of the U-shaped bending part 7 is 75mm, in the cleaning process, water in the through hole 5 generates the same-direction flushing force under the driving of the impeller rotating force, the upper retaining wall 8 and the lower retaining wall 9 are attached to the upper wall and the lower wall of the shovel groove 3 in a sub-packaging mode due to the fact that the upper size and the lower size of the through hole 5 are large and small, no barrier exists along the direction of the through hole 5, and stones and impurities are far away from the through hole 5 under the flushing force. When the opening of the shovel groove 3 is inclined downwards after the shovel groove 3 passes through the highest point of the travel, the stone in the through hole 5 is more likely to slide to the outer side of the groove of the sand washer 1 along the inclined through hole 5 under the action of gravity.

It will be understood that the utility model has been described in terms of several embodiments, and that various changes and equivalents may be made to these features and embodiments by those skilled in the art without departing from the spirit and scope of the utility model. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the utility model without departing from the essential scope thereof. Therefore, it is intended that the utility model not be limited to the particular embodiment disclosed, but that the utility model will include all embodiments falling within the scope of the appended claims.
