Background technique

Can fluidized solids material using negative pressure Dual-Phrase Distribution of Gas olid convey when would generally be shut off with moment by the way of unload loading Material.It is inevitable after shutting off any M branch pipe moment to the manifold fluid system for having N number of branch pipe and a shared negative-pressure air fan Cause the flow of other still working condition branch pipes and pressure in system to change, it is even fierce intuitively to show as flow velocity fluctuation Fluctuation.Practice confirms for many years, substitutes the amount of being trapped with the analogue flow rate for corresponding to each branch pipe one by one and pressure equivalence amount moment Method is the effective ways to solve the above problems.

Binary equilibrium equipment is exactly to generate the flow and the pressure equivalence amount i.e. device of fictitious load, existing binary decision tree Device is formed using split type structure by component combinations such as fixed damper, adjusting damper, silencers.Actually answering It is had the following technical problems in:

1, split type combination, structure is complicated and not compact, and volume is big；

2, the elastic helix chip technology of adjustable dampers requires high, manufactures difficult, at high cost, easy to damage；

3, external inhaling silencer separately takes up space；

4, benchmark and amount are adjusted without mark；

5, appearance needs to be promoted；

6, without long-range control etc..

In view of this, the requirement of balance that balanced pneumatic dispatch is replaced based on binary equivalence, need to generate from stimulated replacement load, Adjusting, control and sound insulation and noise reducing etc. improve binary equilibrium equipment, with lift technique performance and quality, are more in line with life The needs of production.

Utility model content

In order to solve the above-mentioned technical problem, the utility model provides a kind of integrated binary equilibrium equipment.The utility model Technical solution is specific as follows:

Integrated binary equilibrium equipment, including cabinet, tank ends are equipped with air inlet, and air inlet is connect with silencer, cabinet Side is equipped with air outlet, and the discharge pipe of air outlet and box house connects, and spin resistance part is equipped in discharge pipe, discharge pipe is equipped with Slidable adjustment set, so that the adjustable section of the import of discharge pipe.

Further, cabinet side is equipped with the stepper motor connecting with PLC controller, stepper motor output shaft and sliding silk Bar connection, slidable adjustment are sheathed on sliding screw.Driving element is made using stepper motor, matches corresponding electric controller, it can be by being System main control PLC instruction action realizes reliably stepless fine-tunes.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, the technical solution in the present embodiment is carried out it is clear, complete Site preparation description, it is clear that described embodiment is only the example to a part of example of the utility model, rather than whole.Base In the embodiments of the present invention, those of ordinary skill in the art institute obtained under that premise of not paying creative labor There are other embodiments, fall within the protection scope of the utility model.

As shown in Figure 1, the integrated binary equilibrium equipment of the present embodiment, including cabinet 1,1 both ends of cabinet are respectively equipped with first Air inlet 2 and the second air inlet 3, the first air inlet 2 and the second air inlet 3 are connect with intake muffler 8, and 1 side of cabinet is set Have air outlet 5, air outlet 5 is connect with the discharge pipe inside cabinet 1, in discharge pipe be equipped with spin resistance part, outlet air tube opening and Equipped with slidable adjustment set 12, so that the adjustable section of the import of discharge pipe.

1 side of cabinet is equipped with the stepper motor 6 connecting with PLC controller, and 6 output shaft of stepper motor and sliding screw 9 connect It connects, slidable adjustment set 12 is set on sliding screw 9.As limit, the stroke both ends of slidable adjustment set 12 are also set in 1 bottom of cabinet There are first stroke switch 10 and second stroke switch 13,12 touching first stroke switch 10 of slidable adjustment set or second stroke switch When 13, first stroke switch 10 or second stroke switch 13 feed back to PLC controller, and PLC controller carries out phase to stepper motor 6 It should control.

Driving element is made using stepper motor 6, matches corresponding electric controller, can be by system master PLC instruction action, realization can That leans on stepless fine-tunes.

1 side of cabinet is equipped with adjusting handle 4, and adjusting handle 4 is connect with slidable adjustment set 12.1 two sides of cabinet are equipped with cover board 7,7 bottom of cover board and cabinet 1 are hinged.

Spin resistance part be screw rod 11,11 pairs of screw rod enter discharge pipes fluids obstruct so that the flow resistance of fluid with The variation of the import size of discharge pipe and change.Intake muffler 8 is set to inside cabinet 1.

In the present embodiment, slidable adjustment set 12 can be sliding semicircle outer tube, at the top of sliding semicircle outer tube Stress support is equipped with the travelling nut that be adapted to screw rod, screw rod is driven by motor makees position rotating drive outer tube and make horizontal position It moves；Outer tube two sides are fixed on the spherical guide of flow tube two sides, it is ensured that outer tube orients, movement flexibly, finely.

Outer tube displacement location is accurate, situation understands to make, and supports manually adjusting when necessary, is equipped with outside casing It can show outer tube shift length handwheel with a scale.

To ensure safety, prevent when remote control and regulation artificial or failure occurred limit adjust and caused by accident, it is true in design Fixed outer tube displacement beginning and terminal have been equipped with limit switch.

To obstruct the pneumatic noise for entering screw damper, the present apparatus has been equipped with the rotation of short lead multichannel in bidirection air intake mouth Wing formula silencer, is mounted with sound insulating material on casing.

The present embodiment is can be in wink when the flow of branch pipe any in manifold fluid system and pressure occur to shut off at random Between generate corresponding equivalent substitution load, so that system fluidised form be made to remain the device of balance, can be used for production of cigarettes wind-force In wire feed system.

The working principle of the utility model is as follows:

Wind enters from the air inlet of cabinet two sides, enters discharge pipe from discharge pipe import, and with spin resistance part (screw rod 11) it contacts, is finally discharged from air outlet 5, adjust slidable adjustment set 12 as needed to adjust discharge pipe import size.In flow velocity Lower than under Sonic condition, gas can be approximately incompressible fluid；Equal circulation area supports the fluid with equivalent under operating condition Pass through；Isometrical spin resistance part has flow area constant, and flow resistance and lead of screw length are in inverse ratio, with the lead flowed through The proportional characteristic of number.Therefore, after the lead of caliber and spin resistance part determines, changed by sliding semicircle outer tube and flowed The distance (i.e. process) that body flows through conveyor screw is achieved with the fluidised form that flow is close and flow resistance is different, the branch pipe for generating and being trapped Impedance equivalent simulated impedance.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
