Abstract
The utility model relates to a self-locking ball collecting net with lager torque force arms, which is used for continuously cleaning cooling tubes of a turbine condenser of a power plant. The utility model comprises a cylinder body for ball collection, a net board, a rotating shaft, an eduction tube of a rubber ball, a flow guiding board, a transmission device, an execution device and an operating device, wherein the rotating shaft of the net board is arranged on the cylinder body, and the lower part of the net board is provided with a rotating and swinging support seat; two sets of force arms which embracing each other tightly in opposite directions and the self-locking principle are adopted to realize the opening and closing work of the ball collecting net. The push force with a straight travel range, which is outputted by the execution mechanism is converted into the torque in an angle direction through a connecting rod mechanism. Two parallel rigid shafts synchronously transmit the torque to the double arms embracing with each other for realizing the opening and closing movement of the ball collecting net by the linkage of the double arms and sliding ways on the ball collecting net through slide blocks, namely two working states of the ball collection close of the ball collecting net and the ball collection end and opening circulation of the ball collecting net. The utility model is a ball collecting net with the rubber ball for continuously cleanning the condenser and has the advantages of reasonable and simple structure, low movement mechanism abrasion, high operation reliability, good locking performance, no ball clamping, no ball block, low water resistance, stabilization, reliability and good operation performance.
Description
Technical field
The utility model relates to a kind of ball screen of glueballs continuous wash gas trap, is used for the continuous wash of power plant turbine condenser cooling tube.
Background technology
What be applied at present produce has two kinds, the design of Electricity Department Thermal Design institute, the ball collecting device of the movable grid web plate of being made by Qingdao power equipment factory and 1997 third phases of " thermal power generation " magazine are gone up the ball collecting device by the third generation ball screen of Electricity Department Thermal Design institute development of publication, there is following problem in ball screen in its ball collecting device, directly influenced ball collecting rate, thereby influence cleaning performance: 1, have a rotating shaft to support in the middle of the whole grid web plate, under flow action, easily produce distortion, in deformation gap, easily lose; 2, because a slice grid web plate is fixed in the rotating shaft, and rotating shaft had both played fixation, starting power gearing again, therefore, rotating shaft itself can not self-locking in the time of at an arbitrary position, is difficult to guarantee that the grid web plate accurately is rotated in place and causes the gap to be lost.The ball collecting device that the condenser ball of Chinese patent: ZL98222447.8 cleans has solved the problem of losing, and has strengthened self-locking property, has improved ball collecting rate, has improved receipts ball effect.But, in use find gradually, because the screw rod of actuating unit is operated in the recirculated water that has foreign material such as silt particle, serious wear, and long-pending in screw pair a large amount of silt particles are arranged, screw pair bite phenomenon is serious, and its operational reliability is reduced gradually.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of simple and reasonable, the motion wearing and tearing are little, the ball screen of the glueballs continuous wash condenser that operational reliability is good, and the locking performance is good, does not press from both sides ball, do not block ball, water resistance is little.
High pulling torque arm of force self-locking ball screen described in the utility model, comprise ball collecting barrel, web plate, rotating shaft, glueballs fairlead, deflector, transmission, actuating unit and manipulation device, the web plate rotating shaft places on the cylindrical shell, the bottom of web plate is provided with the swing bearing, wherein: be fixed with two on the cylindrical shell and hold the arm of force in opposite directions tightly, two hold the arm of force in opposite directions tightly links to each other with ball screen with slide rail by slide block, and two semicircle platform side surface structures that constitute ball screen are supported by two upper support gudgeons that are fixed in cylindrical shell.Ball screen is the two halves round platform side surface of splitting.The hoop of going up of ball screen has support ring, and support ring is welded in cylindrical shell admittedly.Receiving bulb is a single Zhi Gangguan, is positioned at centre position, the cylindrical shell center of circle.Receive bulb and be subjected to the ball screen obvolvent.The two halves round table surface is symmetrically distributed, the middle ball of receiving.Ball screen is the punch forming of 1Cr18Ni9Ti stainless steel plate integral.
Its operation principle is: the Direct Travel thrust of executing agency's output is converted into angle twisting moment by linkage, by two parallel stiff shafts moment of torsion is passed to the obvolvent both arms synchronously, the slide rail interlock of both arms on slide block and ball screen realizes the netware open and close movement, and promptly the end receipts ball of receiving ball and ball screen of closing of ball screen is opened through-flow two duties.
Described structure is different from traditional dull and stereotyped convertible ball screen and the plug-type ball screen of leading screw fully, and adopts the two folding work of holding the arm of force and self-lock mechanism realization ball screen in opposite directions tightly.Two arm of force slide blocks of ball screen duty and slider track are in self-locking state, it is reliable and stable to guarantee that ball screen closes net, exhausted non-loosening, the possibility of being out of shape, losing, and need open ball screen the time, hold the arm of force in opposite directions tightly and be in stressed optimum position again, behind the stress that has overcome ball screen, can very like a cork ball screen be opened.Ball screen is made of two semicircle platform side tables, receives in the geometric volume that the whole overcurrent fluid of spherical attitude is in complete a, sealing, rule, and joint close is tight, reliable, good rigidly, make simple, process stabilizing.
Transmission mechanism adopts the connecting rod form, the stress point optimal design, and node is few, no dead point, arm of force dynamics and angular distribution are reasonable, executing agency is exerted oneself minimize, and are beneficial to the stable of energy-conservation and system.Adopt long power arm and short cantilever design, and two parallel stiff shafts adopt big Torsion Section again, therefore, the power by executing agency's output is the pure torsion transmission, mechanism's good rigidly.
At the mechanism action characteristics of slow (a folding cycle is about 70 seconds), all nodes adopt copper sheathings design, and are stressed big, stainless dead.The ball screen web plate is that the 1Cr18Ni9Ti corrosion resistant plate is one time punching molded, smooth surface, and no burr is beneficial to the glueballs prolongation in service life.Receive the ball point and be compiled in the centre position of overflow section, flow velocity is the highest herein, is beneficial to the receipts ball.The folding angle has backwashing function greater than the round table surface radian.
Adopt two pairs to go up axle support dictyosome overcurrent element, avoided the power transmission shaft of straight plate opposite opened ball screen, both played the load-bearing effect, play the drawback of inverting action again, stable performance.Adopt the connecting rod drive mechanism, avoided feed screw nut transmission mechanism screw thread track stop up easily, stuck and easily produce the disadvantage of intercrystalline corrosion.
