Description
Technical field
The present invention relates to a kind of industrial pickling equipment, particularly relate to a kind of steel industry that is applied to, metallic substance such as stainless steel and steel alloy are carried out the pickler that surface acid-washing is handled.
Background technology
Traditional pickler adopts open open-air formula mostly, need to be about to the metallic substance of pickling to winch to by driving and to carry out pickling in the pickling tank, and the material that pickling is finished hangs flushing tank again and washes then; Yet this pickler is owing to can't recycle the acid gas that produces in the acid cleaning process, and elegant serious, therefore, one side is serious to equipment corrosion, has shortened the work-ing life of equipment, on the other hand health of operators is also caused serious harm; In addition because pickling tank is stone cistern or made by Steel Concrete, thereby comparatively heavy, be difficult for moving, again because pickling tank often stores the pickle solution of high density, highly corrosive, thereby the pickling tank of being made by above-mentioned material often damages, repairs frequent.
China utility model patent specification sheets CN2258172Y discloses a kind of pickler, a seal casing has been installed on its top at pickling tank, the sealing case comprises left and right case and is separately positioned on aspirating hole and vision slit on the case, the slit is left in junction at two case tops, and flexible bar shaped door curtain is installed in the end of case; The pickler of this structure can be collected most acid gas by the acid gas collecting mechanism, but still has slit and the bar shaped door curtain place effusion of small amount of acid gas by the case top; In addition, the operation of this pickler all is to finish by operator's craft, and level of automation is poor, and labor intensity of operating personnel is big, inefficiency, is unfavorable for the large-scale industrial production of current society.
Summary of the invention
The object of the present invention is to provide a kind of acid gas that can not only effectively prevent from pickling tank, to overflow, and can improve operator's working efficiency, the pickler that is used for metallic substance of reduction labour intensity.
In order to achieve the above object, the technical solution used in the present invention is: a kind of pickler that is used for metallic substance, comprise pickling tank, material basket and acid mist collecting mechanism, wherein the pickling tank upper end is provided with cover plate, the material basket can be put into pickling tank, the acid mist collecting mechanism is communicated with pickling tank top, and this pickler also comprises the lifting device that is connected and the material basket can be put into or taken out pickling tank with the material basket.
Described lifting device comprises guide frame, locomotive and the driving mechanism that is separately positioned on the outside, described pickling tank two ends, wherein the track of locomotive and guide frame rolls or is slidingly matched, driving mechanism and locomotive are in transmission connection, material basket two ends have the handle portion outside the slotted eye that stretches out on the cell wall of pickling tank both sides, and this handle portion links to each other with locomotive.Described driving mechanism can be oil cylinder, and the piston rod of this oil cylinder is connected with described locomotive.Adopt such lifting device, it only is made of several parts, and is simple in structure; And because lifting device is arranged on the outside of pickling tank, thereby acid gas directly do not corrode this lifting device, prolonged the working life of equipment.
Described cover plate can be made of jointly first cover plate that is hinged on described pickling tank upper end respectively and second cover plate, wherein first cover plate and the first cover plate drive unit are in transmission connection, the described first cover plate drive unit comprises first connecting arm and the first lifting cylinder, one end of described first connecting arm is fixedlyed connected with first cover plate, and the piston rod of the other end and the described first lifting cylinder is hinged; Second cover plate and the second cover plate drive unit are in transmission connection, and the described second cover plate drive unit comprises second connecting arm and the second lifting cylinder, and an end of described second connecting arm is fixedlyed connected with second cover plate, and the piston rod of the other end and the described second lifting cylinder is hinged; The described first lifting cylinder and the second lifting cylinder are installed in respectively on the outer wall of described pickling tank.After adopting such structure, space shared when first cover plate and second cover plate are in the open site is less, and simple and reliable for structure, and manufacturing cost is lower, is convenient to make and maintenance.
Adjacent with second cover plate on described first cover plate is equipped with first rubber plate, adjacent with first cover plate on described second cover plate is equipped with second rubber plate, when described first cover plate and second cover plate were in closing condition, described first rubber plate and second rubber plate overlapped mutually.After adopting such structure, the impact sound in the time of can not only reducing by first cover plate and second cover plate greatly and close makes noise become very little, and the structure of overlap joint can make sealing effectiveness become better mutually.
Described acid mist collecting mechanism comprises wind-collecting cover and aspiration channel, and wherein wind-collecting cover is installed on the described pickling tank outer wall, and wind-collecting cover is communicated with aspiration channel, and described wind-collecting cover exports connection by acid mist corresponding on some imports and the pickling tank.After adopting such structure, when the acid gas that produces in the pickling tank by wind-collecting cover and aspiration channel during by the blower fan sucking-off, promptly in this wind-collecting cover, produce negative pressure, thereby the easier wind-collecting cover that enters of acid gas, and can not overflow from slot and the slotted eye on the cell wall of pickling tank both sides that first rubber plate and second rubber plate overlap mutually.
Described pickling tank can be made of plastics; Because the pickling tank that the pickling tank made of plastic material is made than stone cistern and Steel Concrete is in light weight, erosion resistance is stronger, thereby pickling tank is not fragile, longer service life, and also cheap, be convenient to move and change.When the periphery at pickling tank was fixed with the resting support of this pickling tank of supporting, the mounting structure of pickling tank was with more reliable and safety.
Pickler behind the employing said structure, owing to be provided with cover plate in the pickling tank upper end, the acid mist collecting mechanism is communicated with pickling tank top, like this, in acid cleaning process, acid gas is enclosed in the pickling tank by cover plate, prevent that it from overflowing, by the acid mist collecting mechanism acid gas in the pickling tank is all collected in another equipment and handled, thereby prevented that effectively acid gas from overflowing from pickling tank; Again because pickler is provided with a lifting device that is connected and the material basket can be put into or taken out pickling tank with the material basket, like this, the material basket can rise and descend by lifting device in pickling tank, reach in charging back, pickling tank upper end and descend, and behind the pickling tank cover plate closing, continue again to drop to and carry out pickling in the pickle solution, therefore the level of automation height, has improved working efficiency, has reduced labor intensity of operating personnel.
