Description
Technical field
The utility model relates to unloading valve, relates in particular to double-deck turnover panel unloading valve.
Background technique
Present general double-deck turnover panel unloading valve, mainly by last balance staff, on crank arm, down balance staff, lower bent lever, go up ash bucket, upper valve body, go up the liquid catch bar, go up motor, down valve body, down ash bucket, down the liquid catch bar, motor is formed down.Last motor is by last liquid catch bar, and cranking arm in the pulling back and forth makes the balance staff rotation, realizes the sealing of ash bucket and closes.Following motor spurs lower bent lever back and forth and makes down the balance staff rotation by following liquid catch bar, realizes down the sealing of ash bucket and closes.The deficiency of this structure is that there is the Tower Bridge phenomenon in dust, and it is bad to unload grey effect, and cost is higher, to making and the installation requirement height.
The model utility content
Technical problem to be solved in the utility model provide a kind of simple in structure, unload the double-deck turnover panel unloading valve that effective, the cost of ash reduces.
For solving the problems of the technologies described above, the technical solution of the utility model is, a kind of double-deck turnover panel unloading valve, comprise ash bucket, following ash bucket, flap, following turnover panel, go up balance staff, following balance staff, the fixedly connected balance staff of going up of flap, balance staff under following turnover panel is fixedly connected, crank arm on also fixedly connected on the last balance staff, also fixedly connected lower bent lever on the following balance staff, this two crank arm between, the curved arm rod mechanism that realizes flap and following turnover panel sequence alternate keying work is set.
Described connecting rod is that speed reducer drives the power input shaft rotation, be fixedly connected with connecting rod on the power input shaft, the fixedly connected roller in the end of connecting rod, on crank arm and lower bent lever between connect extension spring, roller circularly with on idle running-contact with lower bent lever-the break away from lower bent lever idle running of cranking arm on contacting-breaking away from of cranking arm.Crank arm on described and lower bent lever on all be provided with the groove that matches with described roller.Described roller and described on crank arm and be respectively time of contact of lower bent lever described roller and rotate 1/5th of week age, it is identical that described roller does not contact the time lag of the idle running of cranking arm, and is described roller and rotates 3/10ths of week age.
Owing to adopt such structure, under the extension spring effect, upper and lower ash bucket played strong rapping effect, avoided the Tower Bridge phenomenon of dust, it is effective to unload ash, only is provided with a curved arm rod mechanism, just realized unloading grey function, thus simple in structure, reduced cost.
The beneficial effects of the utility model are: simple in structure, unload effective, the cost of ash and reduce.Volume is little, energy-conservation, grey ability is unloaded in increase.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described;
Fig. 1 is the double-deck turnover panel unloading valve of a utility model structural representation;
In Fig. 1,1, go up balance staff; 2, flap; 3, high-temperature resistant rubber plate 4, power input shaft; 5, connecting rod; 6, roller; 7, extension spring; 8, lower bent lever; 9, down balance staff 10, down turnover panel 11, on crank arm; 12, go up ash bucket 13, upper valve body; 14, following ash bucket 15, following valve body; 16, high-temperature resistant rubber plate 17, high-temperature resistant rubber plate 18, high-temperature resistant rubber plate.
Embodiment
As shown in Figure 1, upper valve body 13 be positioned at following valve body 15 directly over, the upper-end surface of upper valve body 13 is equipped with high-temperature resistant rubber plate 17, the upper-end surface of following valve body 15 is equipped with high-temperature resistant rubber plate 18, last ash bucket 12 and following ash bucket 14 lay respectively in the seal space of upper valve body 13 and following valve body 15, one side of last ash bucket 12 is provided with balance staff 1, and last balance staff 1 is fixed with flap 2 in seal space, high-temperature resistant rubber plate 3 is installed on the flap 2.Following ash bucket 14 is provided with down balance staff 9 with the same side of last balance staff 1, and following balance staff 9 is parallel to each other with the axis of last balance staff 1, and following balance staff 9 is fixed with turnover panel 10 down in seal space, on the following turnover panel 10 high-temperature resistant rubber plate 16 is installed.Control flap 2 can be realized opening and closing of ash bucket 12, and control is turnover panel 10 down, and ash bucket 14 opening and closing under realizing.
Last balance staff 1 is fixed with cranks arm 11, and following balance staff 9 is fixed with lower bent lever 8.On crank arm 11 constantly all the time with flap 2 relative positions, can rotate simultaneously around last balance staff 1.Lower bent lever 8 is constant all the time with following turnover panel 10 relative positions, can be simultaneously rotate around balance staff 9 down, on crank arm 11, lower bent lever 8 lays respectively at the same side of upper valve body 13, following valve body 15, and is positioned at outside the seal space.On crank arm 11 and lower bent lever 8 between be connected with extension spring 7.Last crank arm 11 and lower bent lever 8 between, one power input shaft 4 is set, the axis of power input shaft 4 and last balance staff 1 axis reach down, and the axis of balance staff 9 all is parallel to each other, power input shaft 4 is connected with cycloidal-pin wheel retarder (not shown), and this cycloidal-pin wheel retarder is driven by the motor (not shown).Be fixedly connected with connecting rod 5 on the power input shaft 4, the other end of connecting rod 5 is connected with roller 6.Power input shaft 4 rotates, connecting rod 5 is together with roller 6 rotation at the uniform velocity, on crank arm 11, lower bent lever 8, connecting rod 5 and roller 6 be positioned at the outer side of seal space, the roller 6 of connecting rod 5 ends can with on crank arm 11 and lower bent lever 8 contact, on crank arm 11 and lower bent lever 8 groove that matches with roller is all arranged.
Drive roller 6 rotations during one week when power input shaft 4 rotates, roller 6 rolls in last 11 grooves of cranking arm, and breaks away from then to crank arm 11, roller 6 does not contact with any object, contacts with lower bent lever 8 again, rolls in lower bent lever 8 grooves, break away from lower bent lever 8 then, roller 6 does not contact with any object again.Roller (6) circularly with on (11) crank arm on contacting-breaking away from (11) idle running-contact-break away from lower bent lever (11) with lower bent lever (8) to dally of cranking arm.
Effective in order to unload ash, dust and material have time enough to fall, motor drives power input shaft 4 by the cycloidal-pin wheel retarder and rotates, connecting rod 5 and roller 6 uniform rotation thereupon, on alternately promoting, roller 6 cranks arm 11 and lower bent lever 8, under the effect of extension spring 7, flap 2 and following turnover panel 10 are pressed 2-3-2-3 sequence alternate keying work.Be that roller 6 rolling time in last 11 grooves of cranking arm was 2 seconds, this moment, flap was in the pass closed procedure; Roller 6 was not 3 seconds with any object time of contact; Roller 6 rolling time in lower bent lever 11 grooves was 2 seconds, this at present turnover panel be in the pass closed procedure; Roller 6 was not 3 seconds with any object time of contact.When roller 6 with on crank arm 11 and lower bent lever 8 when not contacting, extension spring 7 shrinks fast, when closing on ash bucket 12, ash bucket 14 plays strong rapping effect down, has avoided the Tower Bridge phenomenon of dust, it is effective to unload ash.Such structure only need be equipped with the motor of a smaller power, and is simple in structure, saves electric energy.Because equipment volume reduces, and can increase the volume of ash bucket, increase the grey ability of unloading.
