Rotational-flow grit chamber with speed regulating and grit discharging functions

Abstract

The invention relates to a rotational-flow grit chamber with speed regulating and grit discharging functions. The rotational-flow grit chamber comprises a water inlet pipe, a chamber body, a water outlet pipe and a bracket, wherein a speed regulating mechanism is arranged above the chamber body; a grit discharging mechanism is arranged below the chamber body; the speed regulating mechanism comprises a power chamber, a cylinder, a first bearing, a driving shaft, a speed regulating component, a limiting component and a plurality of impellers; the speed regulating component comprises a first motor, a conical block and a friction wheel; the grit discharging mechanism includes a separation chamber, a filter screen, a water tank, a drain pipe, a grit pool and a grit discharging component; and the grit discharging component includes a second motor, a screw rod, a second bearing and a brush plate. According to the rotational-flow grit chamber with the speed regulating and grit discharging functions in the invention, the flow velocity of sewage is adjusted by adjusting the speed of the impellers via the speed regulating mechanism; silt is filtered by the grit discharging mechanism and thendischarged; so the practicability of the rotational-flow grit chamber is improved.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a swirl grit chamber with the functions of speed regulation and sand discharge. Background technique [0002] Sewage will inevitably be mixed with mud and sand in the process of migration, flow and collection. If the sand in the sewage is not pre-sedimented and separated, it will affect the operation of the subsequent treatment equipment. The most important thing is to wear the machine pump, block the pipe network, interfere or even destroy the biochemical treatment process. The grit chamber is mainly used to remove sand particles with a particle size greater than 0.2mm and a density greater than 2.65t / m3 in sewage, so as to protect pipelines, valves and other facilities from wear and blockage. Its working principle is based on gravity separation, so the water flow rate of the grit chamber should be controlled so that the inorganic particles with large specific gravity...

Problems solved by technology

[0003] The existing cyclone grit chamber needs to adjust the flow rate of the water flow to achieve the best grit effect, and the price of the governor is high, which increases the production cost. Not only that, the existing cyclone grit chamber, the sand bucket The sand is compacted and difficult to pump, reducing practicality
