Description
Technical field
The utility model relates to a kind of heating unit, particularly a kind of heating unit for large-scale pickling tank.
Background technology
Pickling tank is the container that workpiece is used for holding the aqueous solution, removing metallic surface film in acid cleaning process, is applicable to Power capacitor industry, is widely used in the industrial acid-washed industry such as metallurgy, plating.Be mainly used in Ti-Ni alloy, the various copper aluminum metal such as stainless steel surface acid-washing uses, play oil removing, rust cleaning, descaling, inhibition, press down the effects such as mist, promote the removing of obstinate oxide skin, the difficult scale removal of high temperature particularly generated in heat bundle, annealing, drawing process, greatly shorten scavenging period, prevent the generation of hydrogen embrittlement simultaneously; Suppress the generation of smog, greatly improve production environment; Greatly reduce corrosion of metal speed, the work-ing life of prolongation acid solution at double, finally make product surface clean clean, form the sub-photo structure of uniform silvery white.
Pickling tank needs to heat the pickle solution in it in the course of the work, make its homo(io)thermism necessarily not within the specific limits, existing pickling tank heating unit is all built in pickling tank, poor effect in large-scale pickling tank, heat uneven and make pickle solution temperature inconsistent, finally affecting pickling effect.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of heating unit for pickling tank, and structure is simple, easy to operate, substantially increases heating efficiency, makes pickle solution thermally equivalent, add pickling effect.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of heating unit for pickling tank, comprise heating container and acid-proof heating tube and PLC, described heating container is provided with water inlet and water outlet, described water outlet is positioned at the below of described water inlet, described water inlet is connected with a lift pump, described water outlet is provided with an outlet conduit, described heating container top is provided with some open holess, described acid-proof heating tube is plug-type to be fixed on described open holes, and vertical is arranged in described heating container, the distance H1 of described acid-proof heating tube bottom bottom heating container is 1-2.5cm, described acid-proof heating tube comprises the body that PTFE is made, eduction rod and resistance wire is provided with in body, described eduction rod length L1 is 1:2-3 with the ratio of the length L2 of resistance wire, described heating container is provided with liquid level sensor and temperature sensor, the junction of described liquid level sensor and eduction rod and resistance wire is positioned in same level, described liquid level sensor, temperature sensor, acid-proof heating tube, by electrical connection between lift pump and PLC.
The beneficial effects of the utility model are:
When the utility model uses, be connected in large-scale pickling tank respectively by lift pump and outlet conduit, PLC controls lift pump by the pickle solution suction in pickling tank in heating container, and the acid-proof heating tube now in heating container is started working, suction pickle solution is wherein heated, and be sent in pickling tank by outlet conduit, with this circulating-heating, structure is simple, easy to operate, substantially increase heating efficiency, make pickle solution thermally equivalent, add pickling effect;
Acid-proof heating tube is plug-type is fixed on heating container top, easy for installation, is easy to safeguard, changes, avoid the pickle solution generation seepage in heating container if there is heating tube damage directly to extract;
The junction of liquid level sensor and eduction rod and resistance wire is positioned in same level, when liquid level is lower than derivation rod, information is passed to PLC by liquid level sensor, and PLC controls heating rod and stops heating work, effectively can prevent dry combustion method, reduce spoilage;
The temperature of the pickle solution in heating container monitored in real time by temperature sensor, adjusts the working order of heating tube according to the needs of Heating temperature in real time, makes pickle solution homo(io)thermism in pickling tank.
