Description

The water-repellent paint flush coater

The utility model belongs to spray coating mechanical, particularly be a kind of water-repellent paint flush coater.

The flush coater of general coating is a lot, but the complex structure cost height, the weight that have are big, the use inconvenience that has, for example " the tar polyurethane flush coater " of No. 92203137.1, application number is made up of vehicle frame, motor, reductor, driving oil cylinder, eccentric wheel, hopper or the like, if spraying also exempts to force usefulness on the level land, just be difficult to move if do high-rise spraying, and effort, time-consuming, use inconvenience.When particularly the high-altitude roof of storied building sprays in spraying work, still many with manually smearing.

The purpose of this utility model provides a kind of simple in structure, easy to use, the water-repellent paint flush coater that can work continuously, cost is low, efficient is high.

The purpose of this utility model is achieved in that accompanying drawings is as follows:

A kind of water-repellent paint flush coater, its design feature is:

1. complete machine is made up of the interchange jar 1 on top and the accumulator 2 and the spray gun 3 of bottom;

2. exchange jar 1 upper wall and connect hopper 4 by the pipeline 13 of band valve 14; Exchange between jar 1 upper wall and storage tank 2 upper walls and be communicated with by the last tracheae 5 of being with valve 6; Exchange between jar 1 lower wall and storage tank 2 upper walls and be communicated with by the tremie pipe 7 of being with valve 8;

3. storage tank 2 one end upper walls are provided with the air inlet pipe 9 of band valve 10, and its other end lower wall is provided with the discharge nozzle 11 of band valve 12; Discharge nozzle 11 other ends are communicated with the charging aperture 23 of spray gun 3.

Accompanying drawing 1 is a coating applicators main frame cross-sectional view;

Accompanying drawing 2 is the spray gun structure schematic diagram;

Accompanying drawing 3 is a spray gun example structure schematic diagram.

By accompanying drawing 1 as can be known, this flush coater mainly is made up of main frame and spray gun 3; Main frame 2 is made up of with storage tank 2 the interchange jar of putting up and down 1; Exchange between jar 1 upper wall and the hopper 4 above it and be communicated with by the tremie pipe 13 of being with valve 14; The pipeline 5 that exchanges between the upper wall of jar 1 the storage tank 2 of upper wall with it below by band valve 6 is communicated with, is communicated with by the pipeline 7 of being with valve 8 between the lower wall that exchanges jar 1 and the upper wall of storage tank 2; Upper left wall at storage tank 2 installs an air inlet pipe 9 of being with valve 10 additional, installs the discharge nozzle 11 of a band valve 12 additional at the bottom right of storage tank 2 wall.

The spray gun structure that can be found out coating applicators by accompanying drawing 2 is: on the convenient pikestaff 29 that uses feed pipe 23 and air inlet pipe 26 are housed, be respectively equipped with

valve

24 and 27 on feed pipe 23 and air inlet pipe 26, being combined into an outlet at the end of the outlet 28 of the outlet 25 of feed pipe and air inlet pipe is spray material port; When the outlet of the discharge nozzle in the accompanying drawing 1 11 and the import connection of the feed pipe 23 in the spray gun 3, again gas outlet in the air pump and air inlet pipe 26 are connected, coating in the storage tank 2 is flowed out by the outlet 25 of feed pipe through valve 24 through feed pipe 23, and the pressed gas that air pump produces is entered through outlet 28 ejections of valve 27 by air inlet pipe by air inlet pipe 26; Just can realize that the discharging of outlet 25 sent evenly forth the purpose that realization sprays by the gases at high pressure of discharging opening 28 as long as adjust valve 24 and valve 27.

Accompanying drawing 3 is another embodiment of spray gun 3, spray gun 3 integral body are tubular shape, the material pipe 32 of band valve 33 has discharging opening 24, the tracheae 35 of band valve 36 has gas outlet 37, discharging opening 34 is last, gas outlet 37 under merge into a spray material port, as long as regulate valve 33 and valve 36, discharging opening 33 outlet material can just be sprayed away by the gases at high pressure that gas outlet 37 sprays uniformly can realize having sprayed.

By also finding out in the accompanying drawing 1, in order to grasp the coating mobility status in the storage tank 2, installed one additional and surveyed material pipe 19, make an end of surveying material pipe 19 feed the intracavity bottom of storage tank 2, the other end leads in the outside of storage tank 2, and is provided with valve 20 at external end head; When turning on valve 20, material has just been known the feed liquid situation of storage tank 2 by flowing out in the feed basin 21 that bleeds by surveying material pipe 19 in the storage tank 2; In order to grasp the pressure condition in the storage tank 2, on its tank skin, installed Pressure gauge 22 additional; In order to increase work efficiency, exchange increased between the upper wall of jar 1 upper wall and storage tank 2 band valve 16 on tracheae 15 be connected, be with the tremie pipe 17 of valve 18 to be connected exchanging to have added between the upper wall of jar 1 lower wall and storage tank 2.

For main frame is moved at any time with the expansion of spraying face, below storage tank 2, be provided with roller 31 and driving handle 32, for the safety of storage tank 2, wall is provided with safety valve 30 thereon.

Working condition is as follows: by hopper 4 chargings, open valve 14, material enters through tremie pipe 13 and exchanges jar 1, material enters storage tank 2 through opening valve 8 and 18 from pipeline 7 and 15 again then, valve-off 6 then, 8,18,16 and valve 20 and 12, make the gases at high pressure in the air pump enter storage tank 2 then by air inlet pipe 9, valve-off 10 makes coating mixing in airtight storage tank 2, open valve 12 then, make coating be pressed into feed pipe 23 (see figure 2)s in the spray gun 3 and simultaneously the gases at high pressure in the air pump are entered air inlet pipe 26 in the spray gun 3, adjust

valve

24 and 27 and make feed pipe outlet 25 material that go out all evenly to be broken up ejection by the high pressure gas that air inlet pipe exports 28 ejections can to have begun coating spraying work through discharge nozzle 12.

In spraying work, valve 14 (referring to accompanying drawing 1) is opened, to expect from hopper 4, to enter interchange jar 1 through tremie pipe 13, valve-off 14 then, and open valve 6 and 16, gases at high pressure are entered from storage tank 2 exchange jar 1, material is mixed with gases at high pressure, open tremie pipe valve 8 and 18 then, the material that exchanges in jar 1 is entered under the promotion of the gases at high pressure that entered by pipeline 5 and 15 in the storage tank 2, valve-off 8 and 18 and 6 and 16 more at this moment, the material in the storage tank 2 has obtained replenishing, repeatable operation like this, in time the material that replenishes in the storage tank has carried out coating work continuously with regard to realizing.

Air pump in the work can be with commercially available, is installed on the frame to move with main frame to get final product, and the roller 31 on the main frame can get final product by 2-4 of dress.

Accompanying drawing 3 is another embodiment of spray gun, and usage is similar to accompanying drawing 2.

The utility model advantage is a lot, at first is simple in structure, and is easy to use, as long as with spray painting Machine host is transported to the job site, with main frame, makes pipeline communication good matched air pump, will again The pipeline of spray gun is communicated with main frame and air pump, and reinforced by hopper, the closing valve of having controlled well can be constructed, Pipeline connects the overwhelming majority and can weld, and the pipeline that can roll over dress can get final product well with the screw thread fixed seal connection, So employment is few, simple to operate, sturdy and durable, but the low spraying effect of cost is relatively said in continuous operation Fruit is good. This machine is applicable to the spraying of various coating, paint, is particularly useful for basement three face walls and room The construction of face water-repellent paint.
