Description

Negative pressure dust removal sand washer

Technical Field

The utility model relates to a sand washer field especially relates to a negative pressure dust removal sand washer.

Background

The sand washer is used for desliming and screening a large amount of sand for construction sites, sand and stone factories, prefabricating factories and hydropower sites, can also be used for machines for ore sorting operation, and is generally cleaned by clear water.

However, a large amount of water resources are needed for cleaning the sand and stone, and the water after cleaning cannot be recycled, so that the traditional water washing method has the problem of resource waste.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model aims to solve the technical problem that a negative pressure dust removal sand washer is provided utilizes the fan to produce suction, separates the grit and the dust, reaches the purpose of sand washing and dust removal.

To achieve the purpose, the utility model adopts the following technical proposal:

the utility model provides a negative pressure dust removal sand washer, including the sand washer, the welding of sand washer top central authorities has the sand inlet pipe, and the welding of bottom central authorities has the sand outlet pipe, the welding of sand washer lateral wall surface has the dust absorption pipe, the sand washer inner chamber is provided with the sieve sand table, sieve sand table edge weld in the sand washer inner wall, the sieve sand table surface is covered with the hole that can supply sand to pass through;

preferably, the shape of the sand screening table is conical, and the center of the sand screening table is higher than the periphery of the sand screening table;

preferably, the bottommost end of the dust suction pipe and the topmost end of the sand sieving table are located on the same horizontal line.

The utility model has the advantages that:

the suction force is generated by the fan, the negative pressure is generated at the tail end of the dust absorption pipe, and dust is separated from sand while the sand is screened, so that the dust content of the sand is reduced, and the quality of mortar is improved;

the fan generates suction to remove dust, and water is not needed to be used for cleaning in the dust removing process, so that water resources are saved, and the sewage discharge is reduced.

Drawings

FIG. 1 is a schematic view of an internal structure of a negative pressure dust-removing sand washer according to an embodiment of the present invention;

fig. 2 is a top view of a sand screen in a negative pressure dust removing sand washer according to an embodiment of the present invention.

In the figure:

1. a sand inlet pipe; 2. washing a sand machine; 3. a sand outlet pipe; 4. a dust collection pipe; 5. screening a sand table; 511. and (4) holes.

Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1 and 2, the negative pressure dust removal sand washer provided in this embodiment includes a sand washer 2, a sand inlet pipe 1 is welded at the top center of the sand washer 2, a sand outlet pipe 3 is welded at the bottom center, a dust suction pipe 4 is welded on the surface of one side wall of the sand washer 2, the dust suction pipe 4 is connected with a fan outside the sand washer 2, a sand sieving plate 5 is arranged in the inner cavity of the sand washer 2, the edge of the sand sieving plate 5 is welded on the inner wall of the sand washer 2, holes 511 for sand to pass through are distributed on the surface of the sand sieving plate 5, and suction is generated by the fan, the negative pressure is generated at the tail end of the dust absorption pipe 4, dust is separated from sand and stone while the sand and stone are screened, the dust content of the sand and stone is reduced, the quality of mortar is improved, compared with the traditional water sand washer, the negative pressure dust removal sand washer saves water resources, meanwhile, the discharge of sewage is reduced, the damage to the environment is reduced, and the strategy of national energy conservation and emission reduction is met.

A plurality of sand screening discs 5 can be arranged in the sand washer 2 as required to obtain the mortar with different dust contents.

In order to improve the dust removal effect of the sand washer, furthermore, the sand sieving table 5 is conical, the center of the sand sieving table 5 is higher than the periphery of the sand sieving table 5, and when sand falls on the sand sieving table 5, the sand is scattered to the periphery along the top end of the sand sieving table 5 due to collision, so that the contact area of dust and air is increased, more dust is sucked by the dust suction pipe 4, and the sand washing and dust removal effect is improved.

In order to improve the dust removal effect of the sand washer, furthermore, the bottommost end of the dust suction pipe 4 and the topmost end of the sand sieving table 5 are located on the same horizontal line, if the dust suction pipe 4 is too high, sand and stone fall onto the sand sieving table 5 to start sand washing and dust removal, at the moment, the sand and stone are not fully contacted with air, so that the dust suction effect is not good, when the bottommost end of the dust suction pipe 4 and the topmost end of the sand sieving table 5 are located on the same horizontal line, the sand and stone just fall onto the sand sieving table 5 at the moment, the sand and the air start to be fully contacted, at the moment, the sand washing and dust removal are started, and the dust removal effect of the sand.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the invention. The present invention is not to be limited by the specific embodiments disclosed herein, and other embodiments that fall within the scope of the claims of the present application are intended to be within the scope of the present invention.
