Example Embodiment

[0009] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings:

[0010] Such as figure 1 As shown, the high-efficiency, energy-saving and environmentally-friendly hydraulic pipe pickling device of the present invention includes a pickling tank assembly, a pickling liquid circulating drive device, a bracket, an electric control system, and a heater 15. The pickling tank assembly includes a pickling tank 10, a sediment frame 11, a return pipe 14, a float 7, and a filter screen 13. The pickling tank 10 is an acid-resistant tank with a generally rectangular shape. The grooves are connected by a return pipe 14. The left end of the return pipe 14 is equipped with a filter screen 13, and the sediment frame 11 is arranged in the left groove of the pickling tank 10; the pickling liquid 9 is injected into the pickling tank 10 The float 7 floats on the liquid surface of the pickling liquid in a spherical shape, and the number ...

Abstract

A high-efficiency, energy-saving and environment-friendly pickling device for hydraulic pipe fittings, including a pickling tank with a raised middle and concave sides. The raised part in the middle of the pickling tank is provided with an acid-resistant bracket for placing the pickling pipe, and one side of the pickling tank is concave. There is a sediment frame in the tank, a steam heater is installed in the concave tank on the other side, a return pipe is provided between the concaves on both sides, and a float covering the pickling liquid surface is installed on the upper part of the pickling tank. There is a nozzle at one end of the pickling pipe, and the nozzle is fixed on the distributor. The distributor is connected to an acid-resistant pump through a quick joint, and is equipped with a device to control the on-off of the heater steam and the start-stop of the acid-resistant pump drive motor according to the temperature of the acid liquid. Electric control system. Utilizing the acid delivery pump to realize the circulating flow of the cleaning liquid effectively improves the uniformity of the acid concentration, and effectively improves the cleaning efficiency and cleaning quality; the structure is simple, the acid liquid can flow and circulate, the pickling efficiency is high, and the pickling effect is high. Good, energy saving and environmental protection.

Description

technical field [0001] The invention relates to a high-efficiency, energy-saving and environment-friendly pickling device for hydraulic pipe fittings, which is especially suitable for pickling of high-precision hydraulic pipes for pretreatment before cold rolling or cold drawing. Background technique [0002] Rough pipe cleaning is the first process before the cold rolling or cold drawing process. The quality of the cleaning directly affects the quality of the inner and outer surfaces of the steel pipe after cold rolling or cold drawing (such as smoothness, defects, components, etc.). At present, the acid solution immersion method is mainly used to clean hydraulic pipe fittings. Although the rust on the surface can be removed to a certain extent, because the acid solution for cleaning cannot flow, there are also the following deficiencies: (1) The removal of rust Incomplete; (2) Unable to remove attachments that do not chemically react with acid; (3) Low pickling efficiency;...
