Description
Technical field
The present invention relates to milling apparatus technical field, be specially a kind of efficient circulation wet grinding device.
Background technology
Wet grinding mill is widely used in the various powder body processing industries such as electronics, pottery, chemical industry, medicine, metallurgy, environmental protection.Its operation principle is: the material after premix is sent into grinding chamber by pneumatic diaphragm pump, the material of Rapid Circulation reaches the purpose pulverized by the abrasive media that agitation is fierce, ground material is overflowed by the flash mouth on baffle plate, again in Matter Transfer pipeline returns to again Matter Transfer cylinder, and then send grinding material back to grinding chamber further by pneumatic diaphragm pump, carry out repeatedly circular grinding.The material of Rapid Circulation, by the abrasive media layer of agitation fierceness, is conducive to obtaining narrower particle diameter distribution, it is allowed to less microgranule runs through, and the thickest microgranule to be then detained the longer time, has selective crushing effect to coarse grain.
Wet grinding mill also can be used to carry out many inorganic powder particles broken and reach to control particle diameter and the purpose of particle diameter distribution.These inorganic powder particles include calcium carbonate, calcium oxide, titanium dioxide, aluminium oxide, aluminium hydroxide, magnesium oxide, magnesium hydroxide, Firebrake ZB, barium sulfate etc..The medium being used for being ground includes aluminium oxide, zirconium oxide, silicon dioxide etc..
The zirconium oxide that the abrasive media of original wet grinding mill typically uses particle diameter to be 1.5 to 3.0mm, owing to granule is bigger, grinding efficiency ratio is relatively low, in order to improve grinding efficiency, typically now uses the zirconium oxide that particle diameter is not more than 1.2 instead, and the flash oral pore footpath on baffle plate is 1mm, along with the increase of amount of grinding, partial oxidation zirconium can wear and tear, and diameter can reduce therewith, will overflow together along with material when zirconic diameter is less than 1mm, thus can contaminated material.
Summary of the invention
Technical problem solved by the invention is to provide a kind of efficient circulation wet grinding device, with the problem solving to propose in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions: a kind of efficient circulation wet grinding device, including: grinding chamber, Matter Transfer cylinder, pneumatic diaphragm pump, rod cylindricality shaft, vibrator, supersonic generator, described grinding chamber is connected to Matter Transfer cylinder by circulating line, circulating line downstream between Matter Transfer cylinder and grinding chamber is provided with pneumatic diaphragm pump, the circulating line of pneumatic diaphragm pump side is provided with electromagnetic flowmeter, grinding chamber center of inside is vertically provided with rod cylindricality shaft, rod cylindricality shaft top is provided with baffle plate, baffle plate both sides are provided with flash mouth, flash mouth is provided with stainless steel mesh, vibrator is installed bottom grinding chamber, abrasive media it is filled with inside grinding chamber, grinding chamber both sides are provided with supersonic generator.
The supersonic generator of described grinding chamber both sides is symmetrical arranged.
Described rod cylindricality shaft is provided with some stirring side shoots.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is to arrange 20 mesh～the stainless steel mesh of 30 mesh on the flash mouth on grinder baffle plate.When, after the flash mouth that material passes through on baffle plate, also needing stainless steel mesh less by one layer of aperture again, carry out secondary filter, prevent abrasive media from overflowing with material, the most both ensure that the grinding efficiency of wet milk, turn avoid material and be ground medium pollution；Stainless steel mesh is bolted on baffle plate, convenient to its periodic cleaning.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
In order to make realizing technological means, creation characteristic, reaching purpose and be easy to understand with effect of the present invention, below in conjunction with being specifically illustrating, the present invention is expanded on further.
As shown in Figure 1, a kind of efficient circulation wet grinding device, including: grinding chamber 1, Matter Transfer cylinder 6, pneumatic diaphragm pump 7, rod cylindricality shaft 9, vibrator 10, supersonic generator 12, described grinding chamber 1 is connected to Matter Transfer cylinder 6 by circulating line, circulating line downstream between Matter Transfer cylinder 6 and grinding chamber 1 is provided with pneumatic diaphragm pump 7, the circulating line of pneumatic diaphragm pump 7 side is provided with electromagnetic flowmeter 11, grinding chamber center of inside is vertically provided with rod cylindricality shaft 9, rod cylindricality shaft 9 top is provided with baffle plate 2, baffle plate 2 both sides are provided with flash mouth 3, flash mouth 3 is provided with stainless steel mesh 4, vibrator 10 is installed bottom grinding chamber 1, grinding chamber 1 is internal is filled with abrasive media 8, grinding chamber 1 both sides are provided with supersonic generator 12.
The supersonic generator 12 of described grinding chamber 1 both sides is symmetrical arranged.
Described rod cylindricality shaft 9 is provided with some stirring side shoots.
The operation principle of the present invention is: the material after premix is sent into grinding chamber 1 by pneumatic diaphragm pump 7, through rod cylindricality shaft 9 agitation grinding medium 8, the material of Rapid Circulation reaches the purpose pulverized by the abrasive media 8 that agitation is fierce, ground material is upwards overflowed by the flash mouth 3 on baffle plate 2, in circulating line returns to again Matter Transfer cylinder 6, then send grinding chamber 1 again back to by pneumatic diaphragm pump 7, carry out repeatedly circular grinding.In process of lapping, cooling jacket 5 is cooled down by circulation tap water, it is ensured that the unlikely temperature of grinding chamber 1 is too high and damages, and circulation time is depending on the granularity of final goal product, and product granularity requires the highest, and circulation time is the longest.
In order to improve grinding efficiency, abrasive media 8 uses the zirconium oxide that particle diameter is, and the aperture of the flash mouth 3 on baffle plate 2 is 1mm, increase along with amount of grinding, partial oxidation zirconium can wear and tear, diameter can reduce therewith, will overflow together along with material when zirconic diameter is less than 1mm, thus can contaminated material.
When after the flash mouth 3 that material passes through on baffle plate 2 in the present invention, also need stainless steel mesh 4 less by one layer of aperture again, carry out secondary filter, prevent tiny zirconium oxide from overflowing with material, the most both ensure that the grinding efficiency of wet milk, and turn avoid the oxidized zirconium of material and pollute.And stainless steel mesh 4 increases material and passes through area, can't affect the Negotiation speed of material.Owing to stainless steel mesh 4 is to be bolted on baffle plate 2, convenient to its periodic cleaning.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; the principle that the present invention is simply described described in above-described embodiment and description; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within scope of the claimed invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
