The sand enters the feed end 102 of the sand launder 1 under the conveying action of the conveyor belt 31.

Referring to fig. 1, the sand washing tank 1 is also connected with a water inlet assembly. The water inlet assembly comprises a plurality of water outlet pipes 2, the water outlet pipes 2 are communicated with a water source, a water pump is connected onto the water outlet pipes 2, the water outlet pipes 2 are fixedly connected with the outer side wall of the sand washing groove 1, and the water outlet ends 21 of the water outlet pipes 2 are located above the sand washing groove 1. In particular, in the embodiment of the present application, a plurality of water outlet ends 21 of the water outlet pipe 2 are provided, and the plurality of water outlet ends 21 are distributed at intervals along the length direction of the sand washing tank 1. Under the action of the water pump, water flows out from the water outlet end 21 of the water outlet pipe 2 and enters the sand washing tank 1, and due to the inclination of the ground of the sand washing tank 1, the water is collected at the feed end 102 of the sand washing tank 1 and forms a stirring pool together with sand and stone discharged from the conveyor belt 31. One end of the spiral blade 12 close to the feeding end 102 of the sand washing tank 1 is immersed in the stirring tank, and the spiral blade 12 is driven by the spiral shaft 11 to rotate and push the discharging end 101 of the sand washing tank 1 for sand in the stirring tank. Under the driving of the continuous rotation of the helical blades 12, the sandstone raw material continuously rubs with the water, the friction gaskets and the inner side wall of the sand washing tank 1, so that the closer the sandstone raw material is to the discharge end 101 of the sand washing tank 1, the higher the cleanness degree of the sandstone raw material is. And because the water outlet end 21 of the water outlet pipe 2 is positioned at a plurality of positions above the sand washing tank 1, the falling clean water flow washes the sand driven by the helical blade 12, and the problem that the surface of the sand raw material is still provided with more slurry impurities because the sand raw material is washed by the water with a large amount of slurry in the sedimentation tank is reduced.

When wasing the grit raw materials, often need a large amount of water, water takes place abundant contact with the grit raw materials under helical blade 12's the stirring in the sedimentation tank, and at this moment, the silt on grit raw materials surface, the tiny impurity that alkaline position and probably carried all gets into the aquatic and forms mud, contains a large amount of water in the mud, directly discharges and causes a large amount of water resource waste, and mud has more impurity simultaneously again, does not discharge and directly utilizes the degree of cleaning that has influenced the grit raw materials. Thus, a sewage draining outlet 14 is arranged on the side close to the feeding end 102 of the sand washing tank 1. And a plate and frame filter 4 is connected with the sewage discharge outlet 14. The liquid inlet end 41 of the plate frame filter 4 is communicated with the sewage discharge port 14, and the liquid outlet end 42 is positioned above the sand washing tank 1. The plate and frame filter 4 filters the fed slurry, and the water after the filtering is discharged to the sand washing tank 1 again, so that the water is reused, and the waste of water resources is greatly reduced.

The bottom of the discharge end 101 of the sand washing tank 1 is provided with a sand outlet (not shown in the drawing). The sand outlet is positioned below the two helical blades 12. The lower part of the sand outlet can be connected with a material conveying piece which conveys the cleaned sandstone raw material for the production of gas filling.

Referring to fig. 1, in particular, a supporting frame 5 is provided at one side of the sand washing tank 1 in the length direction. A base plate is erected in the support frame 5, and the height of the base plate is slightly lower than the height of the notch of the sand washing tank 1 from the ground. The backing plate has formed pedestrian's passageway, and operating personnel can observe the washing condition of the grit of washing sand tank 1 inside at pedestrian's passageway on support frame 5, and the function condition of the impurity treatment equipment of this application.

The working process of the raw material impurity treatment equipment in the embodiment of the application is as follows: the sand feedstock is fed through the conveyor belt 31 from one end of the conveyor belt 31 into the feed end 102 of the sand wash tank 1. Meanwhile, water enters the feed end 102 of the sand washing tank 1 from the water outlet end 21 of the water outlet pipe 2 under the action of the water pump, and wets the sandstone raw material which does not pass through the feed end 102. The spiral blade 12 is driven by the rotating motor 110 to rotate, so that the sand and stone raw material is pushed by the spiral blade 12 to the discharge end 101 of the sand washing tank 1. Because the outer bolt of helical blade 12 is connected with friction backing plate 13, when the grit rolls the forward under helical blade 12 promotes, with the full contact of friction backing plate 13, increase the friction to the grit surface. And the water outlet end 21 of the water outlet pipe 2 is provided with a plurality of positions, the falling water flow increases the scrub between the gravels, in the contact process of the friction backing plate 13, the water flow and the bottom of the sand washing tank 1, the impurities on the surface of the gravels raw materials are gradually grinded and removed along with the continuous rising of the gravels towards the discharge end 101, and when the gravels raw materials are cleaned, the gravels raw materials reach the discharge port, and the cleaned gravels raw materials can be discharged.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
