The utility model has the advantages of reasonable and compact structure, high control precision, good operation stability, convenient maintenance, safety and reliability.
Description
Technical field
Novel rotary degree of the uprising high pressure descaling of strip steel descaling device, the particularly concentric collector device that on the hot-rolled sheet strip steel production line, uses that relates to of this use.
Background technology
In the production process of hot rolled strip, the device of degree of uprising high pressure descaling commonly used, but degree of the uprising descaling device that its structure is single spray header device moving up and down to be connected to form with the collector retractor device of mechanical-stretching formula.Also have a kind of degree of uprising high pressure descaling device, form by can upper and lower mobile spray header device connecting high-pressure hose.Above-mentioned degree of uprising high pressure descaling apparatus structure is not compact, and control accuracy is low, and operation stability is poor, and maintenance workload is big, and the easy explosion of high-pressure hose.
The utility model content
The purpose of this utility model is to provide rotary degree of the uprising high pressure descaling of a kind of concentric collector device, and it is rational in infrastructure, compact, the control accuracy height, and good operating stability, easy to maintenance, safe and reliable.
The purpose of this utility model is achieved in that rotary degree of the uprising high pressure descaling of a kind of concentric device, comprise the collector that nozzle is housed, descaling header is made of outer tube and interior pipe, interior pipe is installed in outer tube movingly, radially equal angles is being provided with 3-4 row nozzle sets on the outer tube of descaling header, the nozzle of every row's nozzle sets along outer axial tube to uniform arrangement, the nozzle height of nozzle sets is unequal between each row, the nozzle height of every row's nozzle sets is with corresponding by the thickness of the strip steel of de-scaling, on the position of the normal de-scaling main jet of one row of the corresponding outer tube of interior pipe a row is being set and is often opening the water hole, also be provided with on inner pipe simultaneously and the corresponding nozzle locking device of other row's nozzle of outer tube, interior Guan Yiduan sealing, the other end is connected water under high pressure, in, two ends between the outer tube wall are being provided with rotary positioning apparatus and rotary sealing appts, and motor drives the gear of installing on the outer tube and makes the outer tube rotation.
Wherein one arrange nozzle sets when carrying out de-scaling work on the utility model squama collector outer tube, the nozzle of remaining nozzle sets is by corresponding nozzle locking device sealing on the interior pipe, make the high pressure descaling water can only be after often opening the water hole of interior pipe flowed out, the nozzle sets of working by outer tube ejects.In strip steel de-scaling operation, during along with the varied in thickness of strip steel, motor driving gear rotates a certain angle outer tube, the nozzle sets of corresponding height is forwarded on the position of normal de-scaling main jet, often opening the water hole with the row of one on the interior pipe connects, other nozzle sets is sealed by the nozzle locking device, and this moment, the strip steel to this thickness carried out the high-pressure water jet de-scaling.When the thickness of strip steel changes once more, driving outer tube by motor rotates a certain angle, the nozzle sets of corresponding height is forwarded on the position of normal de-scaling main jet, by that analogy, thereby realized the work of rotary degree of the uprising high pressure descaling of concentric.The utility model is rational in infrastructure, compact, the control accuracy height, and good operating stability, easy to maintenance, safe and reliable.
