METAL DETECTOR AND REJECTION SYSTEM FOR PIPELINE APPLICATIONS

Transcription

1 DEVICE DESCRIPTION This metal detector and rejection system was specially developed to meet high detection and hygiene requirements in the analysis of liquid and viscous products (sauces, jams, marmalades, baby foods etc.). The metal detection device consists of type a MDP Plus-R search coil and MDP Plus-E evaluation electronics - please see relevant data sheets. GATE The MDP Plus-R 8.4 and MDP Plus-R 12 search coils are used depending on the nominal width (NW) of the pipes: Search coil NW 50 NW 65 NW 80 NW 100 MDP Plus-R 8.4 MDP Plus-R 12 OPERATING SENSITIVITY Along with magnetic metal particles, high-alloy steels as well as non-ferrous metals (copper, brass, aluminium, lead, etc.) are also detected. The operating sensitivity of products with a high product effect (all moist, conductive products) is greatly dependent on the product characteristics such as temperature, moisture, salt content, type of conveyance, lumpiness of product additives etc. OUTPUT Different outputs [Q] can be achieved depending on the speed of conveyance and the nominal width of the guide pipe. NW 50 NW 65 NW 80 NW 100 v max [m/s] Q [m 3 /n] Higher conveyance speeds can be achieved in special designs on request. 1

2 PRODUCT GUIDE PIPE The standard version of a non-conductive product guide pipe is a POLYACETAL pipe (other designs on request). SYSTEM PRESSURE FOR POLYACETAL PIPES The maximum permitted system pressure depends on the product and cleaning medium temperature, and the nominal width. Temperature NW 50 NW 65 NW 80 NW C 10 bar 10 bar 10 bar 11 bar 45 C 10 bar 10 bar 8 bar 5 bar 85 C 6 bar 6.5 bar 4 bar 4 bar 100 C 5 bar 5 bar 3 bar 3 bar 120 C 2.5 bar 2.5 bar 1.5 bar 1.5 bar Note: Short-term peak pressures may exceed the permitted permanent operating pressure by 100 %. EJECTOR Various rejection device types are available in accordance with the requirements of the respective application. Requirements can include: cavity free, pipeline pigging system-compatible and CIP cleaning. Multiple-way flap valve (ASV) 3-way arc valve (ABV) Homogenous liquid and viscous mass Liquid and viscous mass with soft solids 2 mm Liquid and viscous mass with soft, fibrous and hard solids 15 mm Cavity free (almost) Pigging system-compatible CIP cleaning possible Available diameter [mm] 50, 65, 80, , 65, 80, 100 The complete exchange of remaining product in the rejection path is achieved by rejection that must be carried out periodically. The ejector is pneumatically activated. The available operating pressure must be 6 bar. Standard Optional 2

3 FLANGES According to customer requirements, various flanges are available for both product guide pipe and rejection device. Flange type (material ) AMV ABV Dairy coupling DIN / Standard Tri clamp ISO 2852 Optional STAND CONSTRUCTION (Option) The stand construction is manufactured completely from blasted stainless steel. The use of lockable guide rollers means that it is easy to move the entire system to where it is needed. The height of the system can be adjusted in the range from 750 mm to 1000 mm using two clamping flanges. CE MARKING Declaration of conformity according to the EMC Directive (2004/108/EC). Declaration of conformity according to the Low Voltage Directive (2006/95/EC). Manufacturer's declaration according to the Machinery Directive (98/37/EC).
