Device for preventing sand blockage of ground source heat pump and separating and discharging sand

Abstract

The invention relates to the technical field of ground source heat pump blockage prevention, and discloses a ground source heat pump sand and stone blockage preventing and sand and stone separating and discharging device which comprises a fixed disc, a top plate is movably mounted on the inner wall of the fixed disc, an air bag is fixedly mounted in the fixed disc, and a sand outlet is formed in the inner wall of the fixed disc. An air guide pipe is fixedly mounted in the sand outlet, and a ball body is slidably connected into the air guide pipe. The moving plate moves upwards to drive the push rod to rotate upwards, the top plate is pushed to extrude the air bag to enable air to enter the air guide pipe, the ball body suspends to block the sand outlet, after an aqueous solution in the fixed disc leaves from the hydrophilic area, the moving plate returns to the initial position, and the air bag is not extruded any more, the ball body falls back to the initial position, and residual impurities in the aqueous solution are discharged from the sand outlet, so that the effects of separating sand from stones in the aqueous solution and independently discharging the sand and the stones are achieved.

Description

technical field [0001] The invention relates to the technical field of anti-clogging of ground source heat pumps, in particular to a device for preventing sandstone blockage of ground source heat pumps and separating and discharging the sandstones. Background technique [0002] Ground source heat pump is a device that transfers low-grade heat energy to high-grade heat energy by inputting a small amount of high-grade energy from shallow land energy. A heating central air-conditioning system composed of a ground source heat pump unit, a geothermal energy exchange system, and a system in a building. [0003] The current ground source heat pump will inevitably extract the clay and sand mixed in the water when pumping ground water, and it will stick to the pipeline during the upward transportation, which may cause the pipeline to be blocked, resulting in ground source heat pump failure. The pumping rate slows down, which reduces the working efficiency of the ground source heat p...
