Description
Technical field
The utility model relates to a kind of flow coat equipment, and particularly a kind of coating machine of Flow Coating, the utility model also relate to a kind of flow coat system.
Background technology
Initial coating machine is all open type, coating is positioned at unlimited charging basket, spray gun is inserted in charging basket directly spray, although this coating machine arranges simply, but, because coating machine opens wide, for the coating that contains a large amount of harmful or inflammable and explosive chemical substance, it is dangerous that the flush coater of open type has increased construction undoubtedly, also easily destroys construction environment.
For fear of the defects of open type coating machine, closed coating machine arises at the historic moment.Chinese patent literature CN2095713U discloses a kind of pot type spraying machine, mainly consisted of by walking chassis and the spray gun that is arranged on the container tank on chassis and sprays coating, sealed tank cap at the top of container tank, cover is provided with the annexes such as air inlet pipe, air bleeding valve charging door and agitating device, the bottom of container tank is taper configurations and with through hole, this through hole and drainage conduit are connected as a single entity, and coating and chemicals are equipped with in the inside of tank body.When work, first the seal cover of charging aperture is upwards mentioned, then by feed pipe, compressed air is injected in tank, utilize air pressure that clout is discharged in the drainage conduit of container tank, then by the discharge flexible pipe, coating is delivered to spray gun, then the compressed air by the air hose feed spray gun dispels coating or atomizes and spray in facing basic unit.Generally, when utilizing this pot type spraying machine, cover and container tank are tightly connected, and only have charging aperture to open wide under off working state, and therefore, this kind flush coater is with respect to the flush coater of complete open type, and the construction when having reduced operation is dangerous.
But also there is following defective in use in this flush coater:
The first, adopt the hand crank that the coating that is positioned at tank is stirred, manual operations, comparatively inconvenience;
The second, because coating is fluidised form, the coating that sprays in facing basic unit easily refluxed before solidifying, but there is not reclaimer in this flush coater, causes on the one hand the waste of coating, has caused on the other hand the pollution to environment yet;
In order to solve the problems of the technologies described above, Chinese patent literature CN201949987U discloses a kind of casting mould flow coater, this flow coater also adopts the tank body of a sealing to come splendid attire coating, and replaces the hand crank to drive the shaft rotation by lubricating oil pump, has solved the inconvenience of hand crank rotation; Simultaneously, this flow coater has increased the reclaimer of accumulator tank as backflow coating, has avoided the waste of backflow coating and for the pollution of environment.
But in above-mentioned prior art, also there is following technical problem simultaneously in disclosed coating machine:
In whole coating procedure, in tank, coating can not carry out self circulating, very easily produce precipitation, in order to prevent the precipitation of coating, need constantly to adopt lubricating oil pump to drive shaft coating in tank is stirred, yet long-time stirring will make the coating in tank constantly heat up, for the coating that contains the flammable and explosive substance such as methyl alcohol, in tank, temperature raises will be very easy to cause and catches fire or the accident such as blast.
Therefore, coating machine of the prior art can't satisfy the defective that prevents the coating precipitation and avoid temperature rising in tank simultaneously.
