Second, the process design:
1, the production line process:
In order to deal more effectively with steel inner and outersurfaces of the oil and phosphate treatment; pre-treatment process thespray treatment process; multi-channel washing countercurrentconnection. This keeps the the workpiece surface clean, but also savewater.
The pre skim 2.0min60 ° C - main skim 3.0min60 of C - washing1.0min-washing-phosphate 4min60 ° C 1.0min 1.0min-table adjustment - 41.0min 1.0min-washing washing - Chit-Chat - drying (120 - 150 ° C 8min) -artificial dust - automatic spray - powder curing drying (180-220 ° Cfor 25min) - cooling - pieces
2, the production line process characteristics:
fully taken into account in the design reliability, advanced,rationality, practicality and economy, its main features are as follows:
Pre-treatment:
Thespray treatment process, rational use of production space.
Thewashed with water after degreasing and phosphating method ofcleaning using a multi-stage reverse complement, add water in and secondslopes washing the rear reservoir overflowing through the pipeline orconveyed to the front of the tank remained behind is often clean liquid,excess fluid through the front of the tank sewage discharge slot;improve the quality of cleaning but also saves water.
Theskim reservoir with a tube heat exchanger equipment, maintain bathtemperature uniformity, while accelerating effect of the workpiecesurface to remove grease.
Thespray tube with pressure regulating device the atomizing nozzle output is more stable.
sprinkler pipe connected with the competent fast-loading, maintenance, easy to install.
spray chamber body at the top of a gantry bracket, both spray shed body ribs, supply tube mount.
pre-degreasing bath, degreasing tank, phosphate bath steam tube heatexchanger heating the entire pre-treatment line reservoir are stainlesssteel plate δ2.0mm, stiffener 60 stainless steel tube and profiles canbe produced. This prevents tank corrosion, and also avoid thedeformation of the tank.
Thespray shed body made of stainless steel shed body, this can increase the life of the product.
nozzle the adjustable the sphere solid cone nozzle, Model: PY6530 type is selected.
hanging chain the QXT-250 type; VVVF drive; hammer tensioning mechanism;
Drying tunnel: the reference German technology, which is characterized by:
drying tunnel insulation board assembly of the "sandwich" structure, insulating layer of 120mm thick high-quality rock wool.
heating: fuel hot air circulation heat exchanger, hot air circulation can take advantage of the energy.
drying tunnel thermal cycling fan with low noise, high temperature,C-type connection type, the impeller 16 Meng material, built-in heatingbox. Motor class F insulation, high temperature motor.
the air supply, the next time the wind of hot air circulation, the useof positive pressure air duct conveying the Supply Duct each outletwith wind control board, uniform temperature distribution in the dryingtunnel.
Conveyor chains:
Conveyor chain selection: the QXT-250 type, pitch 250mm, hanging pitch 500mm;
drive: the cycloid reducer, variable frequency speed control mode, the power to 3kW.
Theprocess speed: V = 3m/min;
Thespeed range: 1 to 6m/min.
rails using 80 × 80 × δ3.75 closed rail the frame attached overhead strengthen, improve the wear resistance and service life.
Electric control:
Theelectrical control dispersed set of centralized control.
entire production line key electrical components selection of importedor national designated factory production of qualified products.Inverter using Mitsubishi products, other vitality of West Germany ofthe products.
u implementation of automatic detection of the temperature of each heating system, display and control.
Thetemperature sensor to connect an optional three-conductor shielded cable, improve signal interference
