Description
The utility model relates to the coating stripping device, and particularly a kind of environment-friendly type metal surface coating stripping device belongs to the coated metal technical field.
In prior art, metal coating lift-off processing aspect there are two kinds of methods, the one, adopt chemical treatment method, promptly,, can remove coating through chemical action in a few days in the hanger immersion acid solution or alkaline solution at a certain temperature, but the processing cycle of this method is longer, floor space is also bigger, need carry out the cleaning of a plurality of operations, wasting manpower and material resources, and the surface of parent often also can be corroded, shortcoming is apparent in view, and people developed various removers afterwards, and were time saving and energy saving, and treatment effect is better, but cost an arm and a leg, and have certain pollution, still have limitation in the use.Another kind method is to handle the coating stripping problem with the way that heating power decomposes, but up to the present, domestic still untapped such coating stripping device, domestic indivedual producers introduce external import equipment, but owing to cost an arm and a leg, most producers can't purchase.
The purpose of this utility model provides a kind of simple in structure, price is lower, efficiency is high, easy and simple to handle, safe and reliable environment-friendly type coating stripping off device.
Task of the present utility model realizes by this way: this device comprises main chamber 1, subsidiary combustion chamber 2, main baking chamber 3, locular wall 8, main burner 10, auxiliary burner 11, cyclelog 20, smoke exhaust pipe 12, venting 13 with cover, temp probe 16, dual-coil electromagnetic valve 14,15, single magnetic valve 18,19, pressure switch 17 etc.Main baking chamber one side dress door, venting with cover 13 is backed down in main baking chamber.Main baking chamber the opposing party is connected with main chamber and subsidiary combustion chamber, main chamber is connected with four air inlets 5 with main baking chamber, the hot-air that is produced by the main chamber burning during work flow into main baking chamber naturally, workpiece is carried out heated baking, the waste gas that produces carries out the second-time burning heating when passing through subsidiary combustion chamber, reach environmental requirement after high-temperature process, and the smoke exhaust pipe 12 by the subsidiary combustion chamber top enters atmosphere again, this process is carried out continuously, till the complete cracking of the coating of surface of the work.The subsidiary combustion chamber side has fresh wind port 4, not only plays auxiliary explosion prevention function, makes the pressure in the stove adjust convenient simultaneously.The locular wall 9 of major and minor combustion chamber all is built into refractory brick, and the top is built into arch, helps the hot-air circulation; Be filled with the heat-preservation cotton of forming by rock wool and alumina silicate fibre 6 in major and minor combustion chamber, the main baking chamber periphery, and adopt stainless steel grid net 7 fixing, increase the attractive in appearance of surface.Main baking chamber doorframe 8 adopts no heat bridge structure, makes main baking chamber outer wall can not be subjected to the influence of main baking indoor temperature, and main baking chamber door has adopted insulation, seal approach, and making that main baking is indoor can anti-certain high temperature, is incubated, favorable sealing property.The outdoor cyclelog 20 that is equipped with of main baking can be imported eight different temperature curves, thereby satisfy the processing requirements of different coating.When the indoor temperature of main baking reaches setting value, lean out temperature and send signal by being contained in the indoor temp probe of main baking to cyclelog, the gas burning system of controlling main burner again carries out the large and small fire conversion automatically, gas burning system and major and minor combustion chamber are connected to the combustion chamber heating, realize thermostatic control; When the temperature of main baking chamber surpasses setting value, the single magnetic valve 18 that is contained in the outdoor one-level water injection system of main baking is opened, be distributed in first group of indoor shower nozzle of main baking to the indoor water spray of main baking, if temperature continues to raise, then single magnetic valve 19 of secondary water injection system is opened, second group of shower nozzle dries by the fire indoor temperature to the indoor water spray of main baking thereby can reduce the master; In addition, when burning at a certain temperature after some small solvent molecule volatilization in the coating of surface of the work, water injection system comes into operation, and dries by the fire indoor water spray to main, thereby can reach the effect of fire extinguishing.The pressure switch 17 of water injection system is connected with power circuit, when water injection system hydraulic pressure is lower than 2.5kg/cm
2The time, pressure switch is closed, and power circuit disconnects, and realizes scarce (owing) water conservation of system.Be provided with dual-coil electromagnetic valve 14,15 in the combustion system of main chamber, subsidiary combustion chamber, pressure switch is arranged in the dual-coil electromagnetic valve, when the gaseous-pressure of gas burning system surpassed or is lower than certain pressure, pressure switch was closed, and gas burning system decommissions.The height and the diameter of smoke exhaust pipe 12 have certain size, by adjusting little negative pressure that these two factors realize main baking chamber, make the airflow smooth circulation.
Advantage of the present utility model: 1. take computer control, can store eight temperature curves, satisfy the processing requirements of different coating.2. the workpiece fertile material is unannealed in the processing procedure.3. Energy Efficiency Ratio higher (80%).4. have lack of water, the protection of explosion-proof and high low pressure, the operation stability height, safe and reliable.5. the waste gas that produces in the heating process of main baking chamber carries out second-time burning through subsidiary combustion chamber, can guarantee to discharge fume and satisfy environmental requirement, and is free from environmental pollution.
