Description
Technical field
The utility model belongs to technical field of dust removal equipment, particularly relates to a kind of pipe negative pressure Equilibrator for regulating dust pelletizing system internal pressure to balance.
Background technique
In dedusting production process, after coke over machinery sends ready signal, ground station for dust removal PLC system sends to blower fan the instruction that runs up, blower fan starts speed-raising, air quantity, blast reach peak instantaneously, and flue gas, under the effect of system negative pressure, enters dust pelletizing system by gas skirt through gathering-device.When system negative pressure exceedes setting value (being greater than 1500Pa), causing dust collector box body to deform because system negative pressure increases suddenly pressure-bearing deficiency and even occur inhaling flat phenomenon, also can there is surging phenomenon because entrance air quantity is too small in blower fan.
In dust pelletizing system high speed operation process, if occurred, dust collector hood valve is unexpected because of fault or manual operation mistake closes, and in whole dust pelletizing system, negative pressure increases instantaneously, causes device damage.
Summary of the invention
In order to solve the problems of the technologies described above; the utility model provides one and dust pelletizing system internal pressure can be regulated to balance; make the pressure stability in dust pelletizing system; can protective system when negative pressure increases suddenly from the flat or blower fan generation surge of suction, maintain dedusting and produce the normal pipe negative pressure Equilibrator effectively run.
The utility model realizes the technological scheme that above-mentioned purpose adopts: this pipe negative pressure Equilibrator is that the valve seat both sides having ventilation window in the plane install shock-proof and damping cylinder respectively, bearing support is provided with above ventilation window, bearing support is provided with rotating shaft, in rotating shaft, socket can the curved bar of synchronous axial system and balance arm around the shaft, the other end of curved bar is fixed along the upper surface threaded fastener of turnover panel and turnover panel, turnover panel just also can shutoff ventilated on window to ventilation window, the end of balance arm is provided with counterweight stone roller, one end of balance arm connection rotating shaft is connected with the flexible rod of shock-proof and damping cylinder.
One end that above-mentioned curved bar and rotating shaft are socketed bends, and the angle between an arm of bending section and the axis of another arm is 145 ° ~ 160 °.
In order to ensure sealing effect, turnover panel internal surface along ventilation window periphery be provided with seal ring.
The working principle of the pipe negative pressure Equilibrator that the utility model provides is: when dust pelletizing system negative pressure reaches setting value (being greater than 1500Pa), turnover panel is opened to the inside, outside air is inhaled in system, intrasystem negative pressure is larger, turnover panel open degree is larger, and the air entering system is more; After air enters, intrasystem negative pressure no longer increases, and reaches a pressure balance point; When the pressure in dust pelletizing system is lower than setting pressure, turnover panel is return under the effect of weight, window aperture seal of ventilating; Overturning for avoiding turnover panel when falling and clash into valve seat, be provided with the cylinder be connected with balance arm in the both sides of valve seat 1, as damping device, by adjusting cylinders cushioning series flow control valve aperture to control airspeed, reaching the object preventing turnover panel shock valve seat.
The utility model structural design is simple; easy and simple to handle; easy to maintenance; effectively can adjust the intrasystem pressure balance of pipeline; even if there is the situation that negative pressure increases suddenly in system, the utility model also can protective system equipment from the injury of inhaling flat or blower fan generation surge and causing, ensure that dedusting is produced and normally effectively to run; make the pressure stability in dust pelletizing system within certain scope, the exhausting amount of system is remained in a metastable scope.

Embodiment
Now by reference to the accompanying drawings the technical solution of the utility model is further described, but the utility model is not limited only to following enforcement situation.
Embodiment 1
As shown in Figure 1, the pipe negative pressure Equilibrator of the present embodiment is connected and composed by valve seat 1, turnover panel 2, balance arm 3, shock-proof and damping cylinder 4, counterweight stone roller 5, bearing support 6, rotating shaft 7, curved bar 8, seal ring 9.
The valve seat 1 of the present embodiment is the connecting body for fixing whole Equilibrator, and it is flange plate type structure, is processed with ventilation window in the in-plane of valve seat, and in ventilation, window place is provided with turnover panel 2, and the rotational of turnover panel 2 controls ventilation window shutoff or open-minded.In order to when ensureing that turnover panel 2 falls and valve seat 1 seal, turnover panel 2 just to ventilation window side on the surface along ventilation window periphery be processed with groove, be embedded with seal ring 9 in a groove.Valve seat 1 is ventilated above window and left and right two bearing supports 6 are installed, connected by rotating shaft 7 mounted thereto between diaxon bearing 6, the middle part of this rotating shaft 7 is socketed with curved bar 8, and two ends are socketed with balance arm 3, makes balance arm 3 and curved bar 8 can around rotating shaft 7 synchronous axial system.One end that curved bar 8 and the rotating shaft 7 of the present embodiment are socketed bends, angle between one arm of its bending section and another arm axle line is 150 °, the other end of curved bar 8 along the upper surface bolt of turnover panel 2 and turnover panel 2 fastening, turnover panel 2 can be driven to overturn when curved bar 8 rotates.The end of the present embodiment balance arm 3 is provided with counterweight stone roller 5, the end bolton of counterweight stone roller 5 and balance arm 3.In order to avoid turnover panel 2 upset fall time and valve seat 1 clash into, shock-proof and damping cylinder 4 is installed between balance arm 3 and valve seat 1, as buffer unit, see Fig. 2 and Fig. 3, the shock-proof and damping cylinder 4 of the present embodiment is commercially available common damping cylinder, in each side installation one of valve body, namely the cylinder body of shock-proof and damping cylinder 4 is fixed by bolts on the sidewall of valve seat 1, the middle part sidewall of flexible rod bolt and balance arm 3 is connected and fixed, series flow control valve aperture is cushioned to control airspeed by regulating on shock-proof and damping cylinder 4, turnover panel 2 is slowly fallen, reach the object preventing valve plate from clashing into valve seat 1.
During use, the valve seat 1 of the present embodiment is arranged on the joint of dust pelletizing system and control of dust main.When dust pelletizing system negative pressure reaches setting value (being greater than 1500Pa), turnover panel 2 is opened to the inside, and outside air is inhaled in system, and intrasystem negative pressure is larger, and turnover panel 2 open degree is larger, and the air entering system is more; After air enters, intrasystem negative pressure no longer increases, and reaches a pressure balance point; When the pressure in dust pelletizing system is lower than setting pressure, turnover panel 2 is return under the effect of weight, window aperture seal of ventilating, and reaches and regulates the pressure balanced effect of pipeline internal system.
