Water filtration sand remover

Abstract

The invention discloses a water filtration sand remover. The water filtration sand remover comprises a shell, a hydrocyclone and an oblique partition plate assembly. A water outlet is formed in the upper end of the shell, a water inlet is formed in the lower end of the shell, and a sand removal opening is formed in the bottom of the shell. The oblique partition plate assembly comprises a plurality of oblique partition plates which are arranged in an inner cavity of the shell at intervals from top to bottom. Every two adjacent oblique partition plates are staggered to tilt downwards, the periphery of each oblique partition plate is connected with the inner wall of the shell in a sealing mode, and a notch is formed in the low end of each oblique partition plate. The hydrocyclone comprises a spindle and a motor. The spindle is arranged in the inner cavity of the shell, and the motor is fixed to the top of the shell. The central axis of the spindle coincides with the central axis of the shell. Each oblique partition plate penetrates through the top of the spindle and extends out of the top of the shell to be connected with the motor, and the bottom of the spindle stretches out of the sand removal opening. The water filtration sand remover has the advantages that the separating effect is good, the separating efficiency is high and the service life of a filter screen can be prolonged.

Description

technical field [0001] The invention relates to a purification device, in particular to a water filter sand remover. Background technique [0002] The desander is made according to the screening principle of solid particles in the fluid when they rotate in the desander. It integrates swirl and filtration, and achieves significant effects in the field of water treatment such as sand removal, turbidity reduction, and solid-liquid separation. Widely used in water source heat pump, water treatment, food, medicine and other industrial sectors. River water, well water desanding, coal washing water, industrial mineral processing, solid-liquid separation, liquid degassing and separation of immiscible liquids. [0003] Its principle: when the water flow enters the equipment tangentially from the desanding water inlet under a certain pressure, it will generate a strong rotational motion. Due to the difference in density between sand and water, under the joint action of centrifugal fo...

Problems solved by technology

[0004] When the sand particles in the water are small and light, the effect of centrifugation cannot achieve sufficient separation.

In addition, when the speed of the water flow upwards is relatively high, it will cause a greater impact on the filter screen and affect the service life of the filter screen.
