Thin Layer Inclined Plate Primary Sedimentation Tank for Silver Beneficiation
It is kind of high efficient combined type settling tank. set many dense inclined tube packing in sediment area, to make the suspended impurity in water sediment, water rise flow along inclined tube, the separated sludge down to the tank bottom along the inclined tube by gravity, then discharge it in concentration. Such tank can improve sediment efficiency 50~60%, it can improve treatment capacity 3~5 times in the same area. It can design different flow rate inclined plate sediment device according to raw waste water test report, it need dose flocculant usually.
Appication
It’s widely suitable for the industrial waste , sanitary sewage , coal mine pit sewage , the non – ferrous metal processing waste water . Power plant ,Bolier room water power dust removal waste water , Liquid – Solid of coal gas station washing . Also suitable for the pretreatment of the water purify
A slurry gravity thickener designed with tilted plate in sedimentation area
Sedimentation Area: 20~3500m2
The inclined plate settler / clarifier is designed to remove particles from liquids. Its theory is put forward on the basis of Shallow tank, which tells the settling efficiency of sedimentation tank is only related to surface area. On LST the settling area is the total area of the inclined plates projected on a horizontal surface.This reduces the footprint of lamella settlers by about 90% as compared to conventional clarifiers and the efficiency of the sedimentation process is multiple increased.
Features
• Heavy duty construction of tank, sludge hopper and lamella plate packs, as well as the rake system. Rake lifting mechanism as option
• Positioning of specifically designed feed ports for optimum ratio between clarification and thickening area
• Wide spacing of lamella plates to handle high density feed pulps and coarse solid particles
• No short circuiting or surface turbulence
• Integrated flocculator with variable speed stirrer
Lower installation costs
• Delivered as one-piece unit or in prefabricated sections
The Work Principle of inclined plate sedimentation
The inclined plate thickener consists of two main components, the upper tank containing the lamella plates inclined at both 55° and 45° according to customers need and the lower conical or cylindrical sludge tank.
The feed for The inclined plate thickener enters through vertical chambers on either side of the plate packs and passes into each plate gap through slotted feed ports. Clarification takes place above the suspension inlet so there is no mixing of the clarified fluid with the incoming feed.
Above each pack is a full-length overflow launder fitted with throttling holes to create a slight hydraulic back pressure on the incoming feed stream. This method of feed control guarantees equal distribution to all inclined plate pack chambers with minimum turbulence at the entry points.
The solids settle onto and slide down each plate pack to the sludge tank where the solids are further thickened and compressed with the assistance of the raking system.
