Particle separation apparatus
Provided is a particle separation apparatus. The particle separation apparatus for separating soil by particle size in a wet-type separation manner includes a body unit providing a space in which a mixture of the soil and water is received to flow vertically, a screen unit coupled to the inside of the body unit to separate the soil by the particle size from the mixture that flows vertically, and a space adjustment unit coupled to a lower portion of the body unit to cover the lower portion of the body unit, the space adjustment unit adjusting a volume of a lower space of the body unit to allow the mixture to repeatedly flow in a vertical direction.
1. A particle separation apparatus for separating soil by particle size in a wet-type separation manner, the particle separation apparatus comprising:
a body unit providing a space in which a mixture of the soil and water is received to flow up and downwards;
a screen unit coupled to the inside of the body unit to separate the soil by the particle size from the mixture that flows up and downwards;
a space adjustment unit coupled to a lower portion of the body unit to cover the lower portion of the body unit, wherein the space adjustment unit comprises a rubber membrane having elasticity, the space adjustment unit adjusting a volume of a lower space of the body unit to allow the mixture to repeatedly flow in a vertical direction; and
a power supply unit coupled to a lower portion of the rubber membrane to vertically move a central part of the rubber membrane up and downwards, thereby adjusting the volume of the lower space of the body unit.
2. The particle separation apparatus of claim 1 , wherein the power supply unit comprises a first power part coupled to the central part of the rubber membrane to move the central part of the rubber membrane up and downwards in a cam manner.
3. The particle separation apparatus of claim 2 , wherein the first power part comprises:
a power source for proving a rotation force by an manual operation or a motor;
a rotor receiving the rotation power from the power source to rotate; and
a first transmission part having one end eccentrically coupled to the rotor and the other end coupled to the central part of the rubber membrane to convert the rotation force of the rotor into a vertical moving force, thereby transmitting the converted vertical moving force into the rubber membrane.
4. The particle separation apparatus of claim 1 , wherein the power supply unit comprises a second power part coupled to the central part of the rubber membrane to move the central part of the rubber membrane up and downwards in a piston manner.
5. The particle separation apparatus of claim 4 , wherein the second power part comprises:
a piston part for providing a vertical moving force; and
a second transmission part having one end that is vertically reciprocated within the piston part and the other end coupled to the central part of the rubber membrane to transmit the vertical moving force of the piston part into the central part of the rubber membrane.
6. The particle separation apparatus of claim 1 , further comprising a support unit supporting the body unit so that the body unit is spaced apart from the ground.
7. The particle separation apparatus of claim 6 , wherein the support unit comprises:
a plurality of supports disposed on the ground; and
an elastic support part coupled between each of the plurality of supports and the body unit to allow the body unit to be movable in a lateral direction.
8. The particle separation apparatus of claim 7 , wherein the elastic support part comprises a spring.
9. The particle separation apparatus of claim 1 , wherein the screen unit is detachably coupled to the body unit.
