Description

Wet Sand Separator {DEVICE FOR SEPARATING SAND}

The present invention is to produce the crushed sand, crushed sand, circulating sand, etc. using aggregate, stone powder, waste concrete, etc., and the sand is selected by a plurality of particles by a single device in which a spiral classifier and a cyclone are combined for productivity and economy. It relates to a wet sand sorting device that provides excellent.

As demand for sand has soared recently, supply and demand imbalance has been caused by the depletion of sand resources.

For this reason, aggregate, stone powder and waste concrete are recycled to produce crushed sand, crushed sand, and circulated sand.

Sand produced as described above is mixed with various particle sizes such as xanthus, so that its utility is lowered, and thus, it is effectively produced because it is washed and dehydrated.

As such, there are a spiral classifier, a cyclone, and the like as a device for sorting sand separately.

The spiral classifier is the most convenient and universally used as a device for classifying, washing, and sorting sand, but is capable of sorting only sand having a large classifying ability.

In particular, as the production of recycled sand to recycle waste concrete increases, small particle sands of more than 200 mesh are lost in water and sludged to be treated as waste.

On the other hand, the cyclone is capable of sorting and separating small particles of sand compared to the classifier, but it is difficult to sort and separate a large number of particles in reality because it has to have a large size of cyclone for sorting and separating the entire sand. Difficulty, of course, because the separation work only by the cyclone, there was a problem that the consumption cost of the inner liner, pump, impeller, etc. is very large.

Therefore, there is a need for a sand sorting apparatus capable of providing a sorting separation of a plurality of particles while simultaneously minimizing the overall manufacturing and management costs, thereby providing workability and economical efficiency.

The present invention has been invented to solve all the problems of the prior art as described above, to effectively fine particles by a plurality of particles in a wet method in a single device in which a spiral classifier and a cyclone mixed sand mixed with various particles and soil powder, etc. The purpose of this is to provide excellent productivity and economical efficiency by collecting and sorting.

The present invention can be equipped with a cyclone compactly, and because the entire amount of the screening operation is not concentrated only by the cyclone, the object is to further maximize the economics by reducing the cost of maintenance, management and internal liners, pumps and the like.

This invention,

A classification tank in which sand and water are mixed into the inlet,

A bucket wheel for rotating feeding and feeding forward by a plurality of buckets formed on a circumference while uniformly mixing the sand introduced into the classification tank;

An upwardly sloped dewatering device for filtering primary sorted sand while discharging fine sand and water downward while transferring the sand supplied by the bucket wheel to an upward slope;

It is achieved by sequentially constructing a primary cyclone and a secondary cyclone, which sequentially filter the second and third sorted sands by supplying the fine sand and water discharged to the lower part from the upwardly sloped dewatering device by a pump.

The classification tank of the present invention is characterized by the installation of the guide plate to guide the mixture of the sand and water flowing into the inlet to be guided downward by the bucket of the bucket wheel effectively.

The present invention provides excellent productivity and economical efficiency by effectively recovering and sorting sand mixed with various particles and soil, etc. by a plurality of particles, particularly fine particles, in a wet method in a single device in which a spiral classifier and a cyclone are combined. Of course, compared to intensively sorting the whole quantity by the cyclone by providing a small cyclone, it is possible to reduce the cost of manufacturing, maintenance, and consumption of internal liners and pumps, thereby providing economic efficiency more efficiently.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, the wet sand screening apparatus of the present invention, the classification tank 10 is introduced into the inlet 12 by mixing sand and water in front of the main body frame 5,

A bucket wheel 40 rotating and feeding forward by a bucket 42 formed on the circumference while uniformly mixing the sand introduced into the classification tank 10;

An upwardly sloped dewatering device 50 for filtering primary sorting sand while discharging the fine sand and water downward while transferring the sand supplied by the bucket wheel 40 upwardly;

The primary cyclone 20 for filtering the secondary screening sand by supplying the fine sand and water discharged to the bottom from the upward inclined dewatering device 50 by the pump (P),

Secondary cyclone 30 is formed by sequentially supplying fine sand and water discharged by overflowing the primary cyclone to filter tertiary sorted sand.

At this time, the secondary screening sand is finer than the primary screening sand, and the tertiary screening sand is finer than the secondary screening sand.

In addition, the inlet 12 of the classification tank 10 is inclined in a zig-zag bent state so that a mixture of sand and water introduced into the inlet is guided to the lower portion to guide the mixed conveyance by the bucket 42 of the bucket wheel. The guide plate 18 which is installed is comprised.

As an unexplained symbol, 2 is a supply hose, 3 is a connection hose, and 60 is a discharge chute.

Hereinafter, the operation and operation of the present invention will be described.

In the present invention, the sand mixed with various particles and soil powder is selected by a plurality of particles in a wet manner.

In more detail, through the supply hose (2) is mixed with the various particles and soil powder, and the recycled sand and water are mixed and supplied to the classification tank (10).

At this time, the inlet 12 of the classification tank 10 is inclined in the guide plate 18 of the jig bent state to guide the mixture of sand and water to the bottom by the bucket 42 of the bucket wheel 40 It will be effectively transported to the forward upward inclined dewatering device (50).

The mixture of sand and water supplied as described above is discharged to the discharge chute 60 by discharging the fine sand together with water to the lower side while filtering the sand of the first sorted sand of the remaining large particles. will be.

In this way, the primary sorting sand of the dehydrated large particles is separated.

On the other hand, the fine sand discharged to the lower side with the water from the upward inclined dewatering device 50 is supplied to the primary cyclone 20 by the pump (P) and the connection hose (3).

As such, the water and the fine sand supplied to the primary cyclone 20 separate and discharge the secondary sorted sand.

In this case, the secondary sorting sand is selected in a fine form compared to the primary sorting sand.

In addition, the very fine sand and water including the sludge overflowed in the primary cyclone 20 is supplied to the secondary cyclone 30 again to separate and discharge the very fine tertiary sorted sand.

In this case, the tertiary sorting sand is finer than the secondary sorting sand.

Therefore, the present invention is mixed and supplied by the bucket wheel 40, which is mixed and regenerated various particles and soil, such as the primary sorting separation by the upward gradient dewatering device 50-secondary by the primary cyclone (20) Separation Separation- By tertiary screening separation by secondary cyclone (30) to provide separation by size of sand particles, in particular, by minimizing the amount of sludge discharged with water to increase the sand recovery rate of the fine particle specifications and excellent commerciality Will be provided.

In addition, the multi-stage sorting of sand allows the cyclone capacity to be applied relatively small compared to the conventional cyclone-only method, thereby minimizing the cost of the cyclone liner consumables.
