Description

[0001] The present invention relates to a sand sorting apparatus,

The present invention relates to a sand separator of a new structure which can improve the drainage speed of drainage of water from water sand to improve working efficiency and improve durability.

Generally, forest aggregates used in construction work are sand and gravel contained in the soil after dumping sand and gravel mixed soil from the mountain.

In this way, the forest aggregate sand collecting work for sorting the forest aggregate is divided into soil, gravel and sand through a multi-stage sorting step in which the soil mixed with sand and gravel is mixed with water, .

As shown in FIG. 1, the sand sorting apparatus used for sorting sand in the forest sand collecting operation is composed of a tubular shape having an opened upper surface, A cyclone 20 connected to the storage tank 10 through a circulation pipe 21 and positioned above the storage tank 10 and a circulation pipe 20 connected to the circulation pipe 21, A pump 30 for supplying water sand stored in the storage tank 10 to the cyclone 20 provided at an intermediate portion of the cyclone 20 and a dewatering screen 40 provided between the storage tank 10 and the cyclone 20, And a transfer means 50 provided at one side of the dewatering screen 40 for discharging the sand selected by the dewatering screen 40.

The storage tank 10 is supplied with water sand mixed with water and sand through a supply pipe 60 connected to one side.

When water sand stored in the storage tank 10 is supplied by the pump 30 to the cyclone 20, the water sand is rotated by the centrifugal force in the inside of the cyclone 20, and the fine particles (fine soil particles) The water sludge is drained through a drain pipe 22 connected to the side with water and the water sludge in which the fine sludge has been removed is discharged to an upper portion of the dewatering screen 40 through an outlet 23 formed in the lower side.

The structure of the cyclone 20 is described in detail in a number of prior documents including the patent document 10-0959586, so that detailed description is omitted.

The dewatering screen 40 is constructed by combining a net screen screen 42 having a plurality of eyes formed on a support frame 41. In a state where the discharge end is inclined upwardly to the upper part of the storage tank 10 Is supported by a spring (43), and a vibrating means (44) is provided at one side and is vibrated at a high speed by the vibrating means (44).

Accordingly, when the water sands whose fine particles have been removed by the cyclone 20 are supplied to the upper part of the dewatering screen 40, water contained in the water sands is discharged to the storage tank 10 through the dewatering screen 40 , The sand filtered by the dewatering screen 40 is moved upward along the slope of the dewatering screen 40 and discharged as the dewatering screen 40 is vibrated.

The conveying means (50) uses a belt conveyor provided under the discharge end where the sand is discharged from the dewatering screen (40).

Therefore, when the water sands having been subjected to the sorting process in the previous step are supplied to the storage tank 10, the water sand is supplied to the cyclone 20 by the pump 30, And the fine powder is discharged and removed.

The water sand from which the fine particles have been removed is supplied to the dehydrating screen 40 and then dehydrated so that only the sand is discharged to the conveying means 50 and then conveyed to the loading stage by the conveying means 50, 40 is recycled to the cyclone 20 after being re-stored in the storage tank 10, and mixed with newly supplied water sand.

The sand sorting device thus constructed has an advantage of effectively dewatering the water sand while effectively removing the fine particles mixed with the water sand.

However, such a sand sorting apparatus is configured so that the eyes of the dewatering screen 40 are very small in order to be able to collect small sized sand at once in the water sand supplied to the dewatering screen 20.
