Abstract
A grinder of solids or solids in liquids has a multiple milling stage. A rotating disc plate carries cutting elements on one side and hammer elements on another, both located at the circumference of the disc plate. The disc plate is rotated in a screened chamber to which the solids or the liquids containing solids to be ground are introduced. Ground product or slurry containing disintegrated solids is passed through the screen before discharged. The use of disc plate and milling elements reduces required torque, leading to improved energy efficiency and results in better performance of the grinder.

In brief, the present invention relates to a kind of solid abrasive in the liquid be become the high-efficient grinding machine of solid-liquid cream slurry, this grinder is drawn into the problem of cream in starching with the formation of eddy current and the air that produces thereupon and is reduced to minimum degree.This grinder comprises a housing, and this housing is provided with a sieve plate, and this sieve plate is divided into first chamber and second chamber with housing.First rotating disk in one first chamber is suitable substantially with the size of first chamber, and can rotate around the vertical axis of central authorities.This grinder also comprises cutting head and hammer, and wherein cutting head is near its periphery and be connected in its periphery on first side of first rotating disk, and hammer is peripheral and be connected in its periphery on second side of first rotating disk near it.One inlet is connecting first chamber, is used for the solid of liquid is imported first side of this rotating disk, and an outlet is connecting second chamber, is used for discharging solid-liquid cream slurry by this outlet.One motor is connected with first rotating disk, and this motor is used to drive first rotating disk.
Fig. 1 is a cutaway view according to an embodiment of the invention;
Fig. 2-4 is the cutaway view according to the multistage grinder of several embodiment of the present invention.
Fig. 1 schematically shows one embodiment of the present of invention.This grinder comprises a housing 10, and this housing 10 is provided with an inlet 12 and one outlet 14.The cross section of this housing 10 is columnar, and is divided into two chambers 16 and 18 by sieve plate 20.One dished plate 22 is arranged in first chamber 16, and is connected on the axle 24, and this axle 24 is suitable for by motor 26 rotation at a high speed.Dished plate 22 has two or more cutting part 28 and two or more hammer parts 30 that are connected to its downside that are connected thereto side.Cutting part and hammer parts are connected on the dished plate 22 circumferentially near it.In another embodiment, dished plate is provided with several bellmouths 32, and these bellmouths are too little concerning the solid that grinds, so that the solid that does not grind can not pass through.The circulation of abrasive product under the dished plate has been improved in these holes.When under the situation that liquid is being arranged during abrasive solid, these holes are especially useful.
Solid in solid or the liquid 12 is imported into grinder by entering the mouth.When dished plate 22 rotation, solid is thrown to sieve plate eccentrically along the passage of rotary cutter 28, and rotary cutter 28 is cut into small pieces solid.Then, these little solid block enter lower area, and rotation hammer 30 is ground into granular size in this lower area, and wherein granular size is the function of the size in hole on the sieve plate.The abrasive solid that is suspended in the liquid is removed by exporting 14.
In this embodiment, the relative existing grinder with the formation of eddy current of the requirement of moment of torsion is significantly improved, and has improved efficiency.These raisings are results of following feature.Substitute one or more vertical rods and make hammer, the present invention uses cutter head and the hammer parts that are fixed on the centrifugal disc.Grind chamber and be divided into two zones.
These improvement are described as follows.If the thickness of blade part is t1, highly be h1; The thickness of hammer is t2, highly is h2; The diameter of dished plate is D, and the inswept volume of cutter head and hammer parts is V1 so, then:
V1=πD(t1*h1+t2*h2)(π=3.14159)
Existing hammer grinder is made hammer with solid metal rods.Suppose that h1+h2 is its height, D is its length, and its inswept volume V2 is so:
V2=πD*D(h1+h2)/4
For for simplicity, suppose that the thickness of cutter head and hammer is identical, i.e. t1=t2=t, then V1 than V2 is:
V1/V2=4.t/D
Usually, as D=4 " time, t=1/8 ", V1/V2=1/8 then.This ratio is determined the strength ratio of two grinder eddy current of no rotating disk approx.But, the setting of dished plate greatly reduced eddy current of the present invention form inswept volume-inlet only can see swept volume V1 ' on the dished plate.Because h1 generally equals 1/3 h2, so
V1 '=π D*t*h1; Or V1 '/V2=t/D,
For size generally speaking, this ratio is 1/32.Therefore, grinder of the present invention only has very little eddy current, thereby few air suction effect is only arranged.When if this little eddy current is still problem, so can be by the horizontal fork of eddy current (vortex-cross) is inserted the inlet of grinder and further reduces eddy current.
Suppose the proportion of s by the inswept solid-liquid body of grinder, r is the distance of component thickness dr to axis, and the ratio of moment of torsion (T1 is a moment of torsion of the present invention, and T2 is the moment of torsion of existing hammer-mill) can easily be drawn by following formula so:
T1=K*mass*distance
2={2πR(h1+h2)t*s}R
2(R=D/2)
T2=K*integral (0 to R) ({ 2 π R (h1+h2) dr*s}r
2)
=2π(h1+h2)s*R
4/4
T1/T2=8t/D=1/4 (t=1/8 here ", D=4 ").Here K is a proportionality constant.
This has just significantly reduced the requirement to moment of torsion.Can predict the analysis of front quantitatively from Fig. 1.When axial rotation, hammer and the inswept zone of blade part only be by be connected the rectangle that forms by the parts shown in the dotted line 32 the part in inswept zone.When the space in the sieve plate is full of by solid, compare with the former, rotating the latter needs bigger moment of torsion.Be not difficult to find out,, also cause the raising of efficiency even the operation moment of torsion is less.
With reference to Fig. 2-4, schematically show other three embodiment.
In Fig. 2, grinder is provided with a single impeller that is fixed on the motor driving shaft 50, and this impeller is centered on by a fixing cylindrical shape sieve plate 52.Impeller has a plurality of by disk 54 and 56 separated grinding stages, wherein disk 54 and 56 with the axle concentric.Grinding component, for example cutter head and hammer are fixed on the disk symmetrically.For example French beans are through the extruding of grinding stage or when being broken into a certain size when solid, and they then enter next finer grinding or broken stage by the opening between disk and the sieve plate.Sieve plate around the grinder terminal stage partly is provided with the hole that the solid that allows final fine grinding is discharged grinder.Although can bore a hole on any position of grinder sieve plate, the reason that does not need to do like this has two: if a) can not flow out sieve plate at the commitment water that grinds, will increase the cream slurry stream between the stage so; B) boring needs cost on material, and promptly the hole is few more, and sieve plate is just cheap more.Concerning some is used, must opening be set at the top of sieve plate, with the local circulation of liquid in the permission grinder and cream slurry.In further embodiments, rotating disk can be provided with porose, for these Kong Taixiao greater than the solid of certain size, so that this solid particle can not pass through.
In Fig. 3 and 4, show multistage grinder, in this grinder, become big disk gradually and be used for better nonferromagnetic substance.
Compared with the prior art, grinder of the present invention can be produced more uniform in grinding Particle size distribution, and energy and power that material is ground are wanted Ask the required degree that is reduced to. The grinding component life-span is longer, and economical production. Of the present invention Grinder also can be produced higher output and better finished product. The present invention be suitable for cereal, spices, Mineral and other drying and grinding edible and non-consumable products; But also be suitable for routine, stagnant The no air of plug, flooded type grinds.
