principle of the installation of water recycling
Installation of water recycling wheel wash trucks designed for water purification from large suspended particles of sand, clay, soil and other contaminants of this nature при этом очищенная вода возвращается на повторное использование.
Таким образом, в системе циркулирует постоянный объем воды, примерно равный 2,5-4,0 м³
Operation of the system occurs in two stages: first - water under the action of centrifugal forces in turbofiltre, the coarse filter and foam filter; second - the deposition of suspended particles under the influence of gravity in the horizontal multi-stage settler.
Contaminated water after washing the wheels merges in the pit or trestle, which is organized directly next to the post wheel wash (on clay soils of the volume of the pit must be at least 2m3, and the sand - not less than 1m3). From the pit, water submersible pump is fed into turbofiltr (device action is based on the use of a centrifugal field forces, where the selection of mechanical impurities from the water occurs under the influence of these forces, which are hundreds or thousands of times greater than gravity, thereby increasing settling velocity of particles).
Rotation in turbofiltre fluid flow is divided into two: the first part of the stream, free of suspension, is directed from the top outlet pipe to the after-treatment in the first receiving container (E1) and the second stream with suspended solids through the bottom outlet nozzle returns to the sump.
water from the first receiving tank installation (E1) flows into the second compartment through a special window, arranged at a certain height to avoid hitting already settled on a suspension system. The water falls in a horizontal decanter.
Horizontal decanter - a rectangular, elongated in the direction of movement of water steel tank in which water moves in a direction close to horizontal, along the sump. Water movement in a horizontal decanter is laminar, and the particles of suspended solids by gravity to precipitate. Sediment accumulated at the bottom sump, from which removed through the pipes (wash away residue with water, unscrew the plug, drain the suspension and the remaining water), or by using a submersible pump (dilute stream sediment water pump with a submersible pump in each tank). Then water from the sump flows into a system of communicating vessels, and then (E2) capacity clean water. Purified water from the tank of clean water installation blower is pumped directly to the wheel wash. Then the cycle repeats.
With installation in frost (to -5 º C) is necessary after the completion of draining water from the high pressure pump through overlapping water tap and short-term inclusion to remove any remaining liquid.
Before working capacity of the installation is filled with water. Starting pressure blower (M4) in the following order: open the tap, inside the control cabinet, circuit breaker, turn, turn to "Start" button M1, press the "button" on a plastic lid relay HydroStop (located next to the gauge on the pump). Submersible Pump (M1 (lowered on a rope to the top of the pit, and run Start button (M3) (for vertical float). Adjusting the frequency of (M3) is achieved by changing the length of the wire float and fixed on the handle of the pump (M3).
