Abstract
The invention relates to the field of charge and provides a charge device for self-centering clamping by air guidance, comprising a base, a rotary disc, a gasket, a locking cover, claws, a substrate, a compressing cover, an electrode ring pressure cover, an electrode ring, air inlets and air outlets. Nozzles are clamped by the claws. The three claws are distributed and installed in the base circumferentially and equally. The claws are connected with the rotary disc through a plane screw. The rotary disc is locked by the locking cover and the gasket. The substrate is connected with the claw through a bolt. The electrode ring pressure cover and the substrate are connected by a thread to fix the electrode ring. The compressing cover and the substrate are connected by a thread. The substrate is provided with compressed air inlets. The air outlets are distributed densely on the compressing cover. Movement of charge liquid drops is limited in an air curtain by guidance of the compressed air, the electrode ring is dry and the charge effect is stable. Due to characteristics of uniform pitches of plane threads, nozzles in different sizes are clamped by self-centering, the electrode ring is small in size and good charge effect can be obtained by lower charge voltage. The device has the advantages that the nozzles are convenient to clamp and the chargeability is high.
Description
Technical field
The present invention relates to electrostatic charged spray field, refer in particular to and utilize high pressure draught formation air curtain to realize water conservancy diversion to charged drop, flat thread drives claw to move radially the integrated charge device of self-centering clamping nozzle.
Background technology
In different engineering applications, the size of droplet is had to different requirements, need to select suitable nozzle.Form of nozzle is various, and size is also different, and fixture that need be different for different designs of nozzles in nozzle type Selection Test, works complicated.In Chinese patent CN1814474 " on-board high-voltage electrostatic multifunctional sprinkling machine ", nozzle, electrode mounting means are difficult to guarantee installation accuracy, nozzle axial line not exclusively overlaps with electrode axial line, and electrode retaining collar size is larger, guarantee the higher charged voltage of the effective charged needs of drop group.
At present in electrostatic charged spray field the most frequently used charged mode to mainly contain contact charged charged with induction type.As patent US5922131 " Electrostatic powder spray coating apparatus with rotating spray orifice ", WO 2007111120 (A1) " Electrostatic atomization device " adopts contact charged, liquid directly contacts with electrode, Insulation Problems is difficult to resolve certainly, therefore, contact Charging Techniques is applicable to powder or the lower liquid of conductance.Induction type is charged utilizes high-pressure electrostatic on ring-type, needle-like or needle ring compound electrode band to form high voltage electric field conventionally, when drop process high voltage electric field, brings electric charge, and this charged mode liquid does not directly contact with electrode.Electrode is exposed in air conventionally, and due to the effect of electrostatic force, partial state of charge droplet deposition greatly reduces charged effect to electrode surface.Chinese patent CN2920427 " composite charging electrostatic spraying device ", for avoiding this situation, is arranged on electrode in insulating barrier, and induction field intensity is low, and charged effect is undesirable.
Summary of the invention
For fear of with overcome above-mentioned deficiency, the object of this invention is to provide a kind of convenient mounting and clamping, charge device for self-centering clamping by air guidance that charged efficiency is high, be applicable to the clamping of different size nozzle, gas flow guiding forms air curtain, electrode retaining collar keeps dry, and electrode retaining collar size is little, required charged voltage is low, can realize efficiently charged.
Charge device for self-centering clamping by air guidance comprises: base, revolve price fixing, pad, tightening cover, claw, pedestal, friction top, electrode retaining collar gland, electrode retaining collar, air admission hole, venthole, it is characterized in that clamping nozzle with claw, three uniform being arranged in base of the circumferential decile of claw, claw with revolve the flat thread with uniform pitch between price fixing and be connected, with tightening cover, pad locking rotating price fixing.Pedestal is connected with bolt with claw, and friction top is with pedestal with being threaded, and pedestal is provided with compressed air air admission hole, and venthole gathers on friction top.Electrode retaining collar gland with pedestal with being threaded, fixed electrode ring.
The course of work of the present invention is, because the line style of flat thread is Archimedes spiral, its pitch equates, circumferentially the uniform three-jaw radial motion distance of decile equates there is self centering effect.Three claws with revolve price fixing flat thread and be connected, price fixing is revolved in rotation, revolve price fixing drives three claws to do radial motion simultaneously, put into nozzle, screw successively price fixing and tightening cover, can realize nozzle self-centering clamping, and to not requirement of jet size, the nozzle of different sizes all can be realized self-centering clamping.Pedestal all adopts with electrode retaining collar gland the formation one that is threaded with friction top, pedestal, and pedestal is connected with bolt with claw.For avoiding causing on charged droplet deposition electrode the phenomenon of charged effect decline, introduce compressed air stream and form air curtain, make aerodynamic force be greater than the effect of electrostatic force, guide charged drop to move in air curtain, assurance electrode retaining collar is dry not to be wet, and obtains stable charged effect with this.
Advantage of the present invention is:
(1) utilize Compressed Gas water conservancy diversion that the motion of charged drop is confined in air curtain, electrode retaining collar keeps dry, charged effect stability;
(2) utilize the feature of flat thread uniform pitch, realize different size nozzle self-centering clamping;
(3) compact conformation, electrode size is little, and charged efficiency is high, can obtain good charged effect under lower charged voltage, saves the energy.
