Abstract
The colloid ball collecting net for the continuous cleaning of steam condenser cooling pipe is steam turbine generator includes ball collecting barrel, netted board, rotating shaft, colloid ball leading out pipe, guide plate, transmission and executing mechanism, and operating mechanism. The netted board set on the barrel has rotating and oscillating bearer in its lower part, the crank-rocker mechanism as the executing mechanism has one link rod hinged to both the rotating and oscillaitng bearer in one end and the crank in the other end, the transmission mechanism has its crank shaft connected to the operating mechanism outside the ball collecting barrel, and the netted board is formed via welding wedged strips. The present invention has less wear in moving mechanism and stable and reliable operation.
Description
Technical field
The present invention relates to a kind of ball screen of glueballs continuous wash condenser, be used for the continuous wash of power plant turbine condenser cooling tube.
Background technology
Turbine condenser uses the automatic continuous wash device of glueballs, can improve the thermal efficiency of power plant unit.The sponge glueballs cleans automatically to condenser cooling tube inwall dirt, therefore, improves the cleannes of cooling tube, improves vacuum, reduces gross coal consumption rate, and can prolong the service life of cooling tube greatly.
The key equipment of condenser cooling tube continuous wash technology is a ball screen, has up to the present carried out repeatedly improving, and improves gradually.The patent No. of the applicant's design is the ball collecting device that the condenser ball of ZL98222447.8 cleans, solve the problem of losing, strengthened self-locking property, improved ball collecting rate, 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 have a large amount of silt particles, and screw pair bite phenomenon is serious, and its operational reliability is reduced gradually.Therefore in addition, existing web plate structure is still owed rationally, still has folder ball, card ball phenomenon, and the problem that water resistance is big also directly affects the runnability of ball screen.
Summary of the invention
Technical problem to be solved by this invention 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.
The ball screen of glueballs continuous wash condenser of the present invention, 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, and the bottom of web plate is provided with the swing bearing, and its actuating unit is a four-bar linkage.
Four-bar linkage comprises the secondary mechanism of circling round of plane rocking bar, crank rocker etc., under thinking enlightenment of the present invention, by changing shape, the size of member, by changing size, the shape of kinematic pair, by selecting different component for use is frame etc., all should think improvement threshold of the present invention, be to be developed by the principle of the invention, and its kinetic property is identical.Principle of the present invention can be applied to other similar field, in other similar equipment, as be applied on the filter of web plate swing or the like.
Among the present invention, our preferred actuating unit is a crank and rocker mechanism, the connecting rod link of swing bearing and actuating unit, and the other end of connecting rod and crank hinge, the crank axle of transmission device links to each other with ball collecting chamber manipulation device outward.
Crank connecting link executing agency is the face contact, and pressure is little, and light abrasion has been avoided motion bite phenomenon greatly, has strengthened operational reliability.The web plate rotating shaft cooperates the swing bearing of web plate bottom, realizes that two point supports, and prevents the web plate distortion, avoids losing.
Web plate can be designed as a whole web plate, forms, rotating shaft and actuating unit are arranged respectively on every block of web plate for two that also can be designed as by symmetry.The ball screen bearing capacity of two web plate compositions is big.The crank axle of two actuating units can connect manipulation device separately, also the crank in the two cover actuating units of two blocks of web plates and the hinge axis of connecting rod can be passed through connecting rod link, thereby realize that two actuating units are by a cover manipulation device control, both simplified structures, handled easily, can realize that again control synchronously, improves operational reliability.Power in the manipulation device of driving crank axle can be electric-powered, also can be manual power.
Two extreme positions of ball screen web plate swing are to receivable ball operating condition and backwash inoperative operating mode, at this moment, and connecting rod and crank conllinear, be called " dead point " position, position locking pieces such as the ratchet in the cooperation manipulation device, ratchet are further strengthened the locking performance, strengthen stable and reliable operation.
Web plate of the present invention is a wedge bar integral solder web plate, and the grating of wedge shape section is welded on the backbar, and the gap is even, and surface smoothing does not press from both sides ball, do not block ball, water resistance is little.
As can be seen, the present invention is simple and reasonable, and the motion wearing and tearing are little, and the locking performance is good, does not press from both sides ball, do not block ball, water resistance is little, and is reliable and stable, and runnability is good, and the power plant that is suitable for various different water sources uses, and is applicable on any ball collecting device.
