Abstract
The utility model relates to a rotating cup type pneumatic sprayer which is composed of a rotating cup, a feeding nozzle, an air motor (a rotor, a stator and a blade), a stock tube, a split flow head, etc., wherein, the stock tube goes through the middle part of the rotor; the external diameter of the utility model can be reduced. Waste gas exhausted by the air motor is exhausted to a place which is far away from a spray head through the stator and a gas outlet groove of the split flow head, so the exhausted waste gas is prevented from polluting a coating layer. The rotating cup is in a cone shape, and is provided with a refining section, a spray hole section and a flange. The utility model has the advantages of uniform coating layers and good atomization effect of coating materials. The utility model has obvious effects when a slender tube (the tube diameter is from 32 mm to 720 mm) is used for spraying coating materials with high viscosity.
Description
The utility model belongs to the spray equipment of flow-like coating.Flow-like coating is delivered to the material pipe by pump pressure, is chewed in the revolving cup that is sprayed onto rotation at a high speed by the feed of material pipe front end, and coating passes revolving cup under centrifugal action spray orifice is the vaporific surface of the work (on inside pipe wall) that is sprayed onto.
There is the gas blowout coating device to be unsuitable for spraying and contains the high high viscosity coating of solid constituent; Existing pneumatic rotary-cup type sprayer, the extra quality tubular type sprayer as the PA-TEIJIN company of the U.S.-Japan joint venture is equipped with two feeder sleeves outside the air motor shell, and it is bigger to take up space, and is unsuitable for spraying in the small-bore pipe; In addition, directly discharge by the stator groove from the waste gas that air motor is discharged, as when being coated with nozzle wall then waste gas easily pollute coating and pipe internal surface to be coated with.
Be used for the problem that spraying exists in high viscosity coating, the small-bore pipe for solving existing sprayer, pneumatic rotary-cup type sprayer of the present utility model has been done following improvement: a material pipe passes through in the middle of rotor, dwindle sprayer hoop cross dimensions, can be suitable for spraying in the small-bore pipe; At the stator and the shunt head outside air discharge duct is arranged, the air motor combustion gas can be discharged in quilt by this air discharge duct and is coated with outside the pipe, thereby can prevent the exhaust emission coating that air motor is discharged and treat the coated pipe surface, influences coating quality.
According to the utility model, its revolving cup can have an annular lip at the revolving cup mouth near at the bottom of the revolving cup refining section (no spray orifice section) being arranged.Chew when being sprayed onto revolving cup refining section coating when coating by feed and be homogeneous film and enter revolving cup spray orifice section, ejection coating is atomized; When spraying stopped, residual coating was blocked by flange, can prevent residual coating trickling, influenced the coating surface quality.
This pneumatic rotary-cup type sprayer structure is as accompanying drawing.
Fig. 1: pneumatic rotary-cup type sprayer master cutaway view of the present utility model;
Fig. 2: the revolving cup master cutaway view of pneumatic rotary-cup type sprayer of the present utility model.
Among Fig. 1: the 1-revolving cup; The 2-feed is chewed; 3-expects pipe; The 4-rotor; The 5-sealing ring; The 6-bearing; The 7-drive end bearing bracket; The 8-stator; The 9-blade; The 10-rear end cap; The 11-shunt head; The 12-housing; The 13-short circuit; The 14-connector; 15-gas joint; The 16-air discharge duct; The 17-alignment pin; 18-expects joint.
Among Fig. 2: A-refining section; B-spray orifice section; The C-flange.
This pneumatic rotary-cup type sprayer working condition of accompanying drawings: compressed air is entered by gas joint (15), shunt head (11) and promotes blade (9) in the space between stator (8) and the rotor (4) rotor (4) is rotated, and drives revolving cup again and rotates.Fluid-coating advances feeding pipe (3) by material joint (18), shunt head (11) under pump pressure, chewing (2) by feed is sprayed onto in the revolving cup (1) that rotates at a high speed, coating flow to spray orifice section (B) by the refining section (A) of revolving cup (1), coating is sprayed by spray orifice under centrifugal action, is sprayed on surface of the work.Residual coating was blocked by the flange of revolving cup (1) (C) when spraying stopped.
This pneumatic rotary-cup type sprayer is because the hoop cross dimensions can be very little, can be used for spraying caliber and be spraying in 32～720 millimeters the pipe, coating can adopt the high viscosity coating that contains the higher solids component, its viscosity can be up to 250 seconds, can be used for containing the liquid epoxy base coating spraying of solid particle granularity≤50 micron, one time coating thickness can reach 200 microns (dope viscosity is 165 seconds), there is not resilience in the spraying, the coating atomizing effect is good, coating is even, when dope viscosity was 160～250 seconds, its revolving cup tapering was that 1:5 can obtain best atomizing effect.The uniformity coefficient of its coating is compared with the coating layer thickness of SUMITOMO CHEMICAL company, NKK drilling rod that company is coated with and is seen Table.
| Company | The utility model | The Sumitomo | NKK |
| Thickness calibration (micron) | 125～225 | ≥125 | 125～225 |
| Actual measurement thickness (micron) | 139～219 | 163～284 | 174～219 |
Embodiment: coating epoxy available base fluid body coating wherein contains solid constituent 45%(weight meter), solid particle granularity≤50 micron, dope viscosity 200 seconds.Revolving cup tapering 1:5, rotating speed 2～2.5 ten thousand rev/min, compressed air pressure 0.67～0.98 MPa.Be coated with the drilling rod that workpiece can adopt 82 millimeters of internal diameters, long≤9.7 meters of drilling rod.Spraying back coating dry film thickness is 139～219 microns.Change the revolving cup tapering from 1:1 to 1:15, the most even when its coating layer thickness is 1:5 with the tapering.
