Description
Technical field
The present invention relates to a kind of core level high-precision electric filter blowdown funnel elastic sealing device.
Background technique
Core level high-precision electric filter comprises the filtration web-roll core outside the blowdown funnel be arranged on main shaft, blowdown funnel, the transmission device driving blowdown funnel to rotate and shell etc., Stamping Steel Ribbon is respectively arranged with on the both sides side plate of blowdown funnel and on the lattice dividing plate of web-roll core, gap between Stamping Steel Ribbon is little as far as possible, to reduce water leakage, thus ensure the backwash water yield of screen surface, improve filth-discharging effect.In conventional design, two Stamping Steel Ribbons are stationary structure.Once by the impurity bite of larger particles between Stamping Steel Ribbon, blowdown funnel just cannot rotate; Or filter is in During Process of Long-term Operation, make blowdown funnel generation radial deflection because of main shaft supporting sliding bearing abrasion, cause two Stamping Steel Ribbons to be interfered, blowdown funnel also cannot rotate, thus becomes Block failure, affects the normal operation of electric filtering apparatus.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide in a kind of blowdown funnel rotary course, slipper seal bar and fixing seal bar can not produce interference, avoid the core level high-precision electric filter blowdown funnel elastic sealing device occurring Block failure.
The object of the present invention is achieved like this:
A kind of core level high-precision electric filter blowdown funnel elastic sealing device, it comprises elasticity sliding motion Stamping Steel Ribbon device and the fixing seal strip device outside it, described elasticity sliding motion Stamping Steel Ribbon device is arranged at the side plate outer end of blowdown funnel, elasticity sliding motion Stamping Steel Ribbon device comprises the fixing frame of the rectangle being fixedly installed on side plate outer end, described fixing frame offers one draw-in groove in lateral, first bolt is had to pass from the two side of fixing frame, first bolt is set with a slipper seal bar, be provided with between the perforation at described slipper seal bar center and the first bolt and make a concession gap, the inner of described draw-in groove to slipper seal bar the inner between be connected with spring, compressive state is under spring nature, described fixing seal strip device is arranged on the web-roll core partition board outside blowdown funnel, described fixing seal strip device comprises the fixing seal bar of L shape, fixing seal bar is fixedly installed on web-roll core partition board by the second bolt, fit up gap between slipper seal bar and fixing seal bar controls between 0.1 ~ 1.0mm.
First straight section of the fixing seal bar of L shape and fixing seal bar and web-roll core partition board are fixedly mounted by the second bolt, and the second straight section and the slipper seal bar of the fixing seal bar of L shape are oppositely arranged.
Slipper seal bar end face is processed with 25 ° of wedge angles, and fixing seal bar end face is processed with 25 ° of wedge angles.
3 ~ 5mm gap is kept between slipper seal bar and draw-in groove.
Pocket edges is processed into fillet.
Compared with prior art, the invention has the beneficial effects as follows:
Core level high-precision electric filter blowdown funnel elastic sealing device of the present invention in blowdown funnel rotary course, if there is the impurity of larger particles to be stuck between slipper seal bar and fixing seal bar; Or after filter long-time running, main shaft sleeve weares and teares, and blowdown funnel offsets to one side, and causes interfering between slipper seal bar and fixing seal bar.Now slipper seal bar is automatically drawn back and is allowed, and avoids the generation of Block failure.Therefore the present invention has in blowdown funnel rotary course, and can automatically draw back when slipper seal bar and fixing seal bar are interfered allows, and avoids occurring Block failure, ensures the advantage of the continuous safe operation of filter.

Embodiment
See Fig. 1 ~ Fig. 2, a kind of core level high-precision electric filter blowdown funnel elastic sealing device that the present invention relates to, it comprises elasticity sliding motion Stamping Steel Ribbon device and the fixing seal strip device outside it, described elasticity sliding motion Stamping Steel Ribbon device is arranged at side plate 1 outer end of the blowdown funnel in sector structure, elasticity sliding motion Stamping Steel Ribbon device comprises the fixing frame 2 of the rectangle being fixedly installed on side plate 1 outer end, described fixing frame 2 offers one draw-in groove 5 in lateral, first bolt 3 is had to pass from the two side of fixing frame 2, first bolt 3 is set with a slipper seal bar 4, the yielding gap of 3mm is provided with between the perforation at described slipper seal bar 4 center and the first bolt 3.The inner of described draw-in groove 5 to slipper seal bar 4 the inner between be connected with spring 6, be in compressive state under spring 6 nature.Described fixing seal strip device is arranged on the web-roll core partition board 7 outside blowdown funnel, described fixing seal strip device comprises the fixing seal bar 8 of L shape, fixing seal bar 8 is fixedly installed on web-roll core partition board 7 by the second bolt 9, first straight section and the fixing seal bar 8 of the fixing seal bar 8 of L shape are fixedly mounted by the second bolt 9 with web-roll core partition board 7, and the second straight section and the slipper seal bar 4 of the fixing seal bar 8 of L shape are oppositely arranged.As shown in FIG., be counterclockwise rotate when blowdown funnel rotates, namely slipper seal bar 4 is free end sides that the second straight section is put in fixed end one lateral movement of the second straight section of fixing seal bar 8 from L shape.
In whole core level high-precision electric filter, be provided with four layers from top to bottom, because blowdown funnel comprises two side plates, therefore core level high-precision electric filter blowdown funnel elastic sealing device adds up to eight groups.
Slipper seal bar 4 adopts ZQSn6-6-3 tin bronze to make, and fixing seal bar 8 adopts 316L stainless steel to make.
Wherein: the height of blowdown funnel is 1600mm, slipper seal bar 4 end face is processed with 25 ° of wedge angles, keeps appropriate gap, be advisable with 3 ~ 5mm between slipper seal bar 4 and draw-in groove, the impurity clamping stagnation slipper seal bar 4 in water of condensation should be prevented, too wide arc gap should not be formed again.
Slipper seal bar 4, from as far as possible short by length overhanging in draw-in groove, prevents the tangential resistance be subject in blowdown funnel rotary course, makes clamping stagnation between slipper seal bar 4 and draw-in groove.
Pocket edges is processed into fillet, avoids acute angle clamping stagnation elastic sealing strip.
Fixing seal bar 8 end face is processed with 25 ° of wedge angles.
Fit up gap between slipper seal bar 4 and fixing seal bar 8 controls between 0.1 ~ 1.0mm, and sewage backwash ability can be fully guaranteed.
In blowdown funnel rotary course, if there is the impurity of larger particles to be stuck between slipper seal bar 4 and fixing seal bar 8; Or after filter long-time running, main shaft sleeve weares and teares, and blowdown funnel offsets to one side, and causes interfering between slipper seal bar 4 and fixing seal bar 8.Now slipper seal bar 4 is automatically drawn back and is allowed, and avoids the generation of Block failure.Maximum yielding stroke presses 3mm design, enough ensures filter safe operation.
