Description
Technical Field
The invention relates to the field of paint production, in particular to a dispersing and grinding device for paint production.
Background
Paint name in English is paint or coating. Paint is a chemical mixture coating that can be firmly covered on the surface of an object for protection, decoration, marking and other special purposes. The ' coating process ' book which is relatively authoritative in the Chinese coating world is defined in the following way that ' the coating is a material which can be coated on the surface of an object by different construction processes to form a continuous solid film with firm adhesion and certain strength. The film thus formed is generally called a coating film, also called a paint film or a coating. The paint is generally composed of four parts, namely a film forming substance, a filler (pigment and filler), a solvent and an auxiliary agent. The components may be slightly changed according to the performance requirements, for example, the varnish has no pigment and filler, and the powder coating can have no solvent.
The paint undergoes a grinding process during the production process, i.e. the filler is ground into powder, and currently, the paint grinding machine consists of a feeding system, a dispersing system, a grinding system, a paint mixing system, a discharging and filtering system, a filling system, a control system, an operation platform and a color paste production part. The most central one is the grinding system which directly determines the fineness of the particles in the paint, and the prior art has the defects that the particles ground by the paint grinding device are not uniform enough and usually contain some larger particles.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, and provides a dispersing and grinding device for paint production, which can realize uniform grinding of paint filler and solve the problem of non-uniform grinding in the prior art.
The purpose of the invention is realized by the following technical scheme:
a paint produce is with dispersion grinder device includes:
the grinding channel is vertically or obliquely arranged, and the upper end and the lower end of the grinding channel are respectively provided with a feed inlet and a discharge outlet;
a first grinding roller and at least one second grinding roller are sequentially arranged in the grinding channel from top to bottom, and a vibrating screen is respectively arranged right below the first grinding roller and the second grinding roller;
the air nozzles are symmetrically arranged above the vibrating screen and connected with the fan to provide positive and reverse blowing air to the upper part of the vibrating screen.
The traditional grinding equipment has the problem of uneven grinding, and the main reason is that the ground particles are pressed together, and even if secondary grinding is carried out, the problem that the ground particles cannot be ground due to incomplete dispersion still exists. In order to solve this problem in this scheme, from top to bottom set up a plurality of grinding rollers in same grinding passageway, also can grind many times, simultaneously all set up shale shaker and air nozzle after each layer is ground in order to guarantee to grind the effect, the purpose of shale shaker is for the dispersed granule rather than realizing the sieve material in this scheme, furthermore, still realize positive blowback through the air nozzle of positive and negative setting and sweep the wind, further sweep the granule, this in-process, the great filler of granule sinks earlier, get into the next floor through the shale shaker, the dispersion of filler has not only been realized, hierarchical sieve material has still been realized, after the multilayer is ground, can realize even grinding, in order to guarantee the even grinding of filler.
Further, the number of the second grinding rollers is more than two, and in principle, the larger the number of the second grinding rollers is, the better the grinding effect is.
Further, the first grinding roller and the second grinding roller are driven by a motor, and the motor is fixed on the outer wall of the grinding channel.
Furthermore, two sides below the vibrating screen are respectively provided with a baffle, and the two baffles form a V shape. The V-shaped grinding roller is convenient for collecting materials, so that paint filler can smoothly enter the next grinding roller.
Furthermore, at least two air nozzles are symmetrically arranged above the vibrating screen. The more the number of the air nozzles is, the better the purging effect is, and the better grinding effect can be ensured.
Furthermore, the air nozzles extend out of the side wall of the grinding channel, and the air nozzles on the same side are connected with the same air pipe.
Furthermore, a butt flange is arranged on the air pipe, and the fan is connected with the butt flange through a pipeline and used for providing blowing air for the air nozzle.
Further, the first grinding roller and the second grinding roller are respectively composed of a driving roller and a driven roller, the driving roller and the driven roller are tangent to each other, and the driving roller is driven by the motor.
Furthermore, the outer sides of the driving roller and the driven roller are respectively tangent to the inner walls of the corresponding grinding channels.
Furthermore, a vibrating motor is fixed below the vibrating screen.
The invention has the beneficial effects that: in this scheme, owing to used the positive and negative deconstruction of sweeping wind and shale shaker, not only realized the homodisperse of paint filler grinding in-process, still realized the classified screening of different particle thickness, sweep the in-process, the large granule rate gets into the next layer through the shale shaker earlier and grinds, has avoided the problem that the fine grain filler wrapped up the large granule filler, has just also improved the grinding degree of consistency of filler.
