Abstract
The utility model relates to a milling device, in particular to a vertical sand mill with a novel internal structure. The sand mill comprises a milling cylinder and a main shaft, wherein a feed port is formed in the bottom of the milling cylinder; and a filter is arranged at the upper part of the milling cylinder. The sand mill is characterized in that a scattering disc is mounted on the main shaft; and a plurality of support pin rods are arranged on the inner wall of the milling cylinder. The vertical sand mill is high in milling efficiency and small in abrasion and heating. Compared with the prior art, the vertical sand mill has the advantages as follows: the milling efficiency is improved by 10%-30% compared with the same scattering disc type sand milling fineness, the milling circulation times are decreased, and the productive efficiency is improved; and medium particle sizes can be distributed more uniformly, and the distribution even dyeing performance is better.
Description
Technical field
The utility model relates to milling apparatus, is specifically related to a kind of vertical grinding machine of new-type internal structure.
Background technology
Vertical grinding machine is widely used in the chemical industries such as dyestuff coating, pigment, printing ink, printing and dyeing mill base.The technique of current vertical grinding machine mainly contains two kinds of forms, and a kind of is to drive the abrasive media of inner barrel by the rotation of radial dispersion impeller; Another kind is to arrange the pin rod on mover and stator, by the pin rod on mover, drives abrasive media.Energy density in latter's cylindrical shell is higher, therefore grinding effect is better, higher but the latter also requires the heat radiation of cylindrical shell, so cost is higher, and another problem of pin bar type structure is due to the high velocity impact of pin rod with abrasive media, makes the pin rod milling damage very soon.
Summary of the invention
The purpose of this utility model is that a kind of grinding efficiency of design is high, and little vertical grinding machine weares and teares and generate heat.
To achieve the above object, the utility model adopts following technical solution: a kind of vertical grinding machine, comprise grinding cylinder and main shaft, bottom at described grinding cylinder is provided with charging aperture, top at described grinding cylinder is provided with filter, it is characterized in that, on described main shaft, dispersion impeller is installed, be provided with some backing pin rods on the inwall of described grinding cylinder.
The utility model is in order further to improve grinding effect, and technical scheme is further arranged: described pin rod is arranged on the inwall of described grinding cylinder twist.
The utility model, in order to increase the density of grinding cylinder bottom abrasive media, further arranges technical scheme: described pin rod helical arrangement direction and dispersion impeller direction of rotation.
The utility model is usingd dispersion impeller as mover, leans on the rotation of dispersion impeller to drive the rotation of the abrasive media of inner barrel, and installs the pin rod additional at the grinding cylinder inwall place of stator, and pin is excellent with helical pattern, the hand of spiral and dispersion impeller direction of rotation.Dispersion impeller can effectively drive abrasive media, medium is had and grind required kinetic energy, and being coated on dispersion impeller abrasive rubber on every side can effective less friction and impact.Medium pushes to the cylinder inboard wall place under the effect of centrifugal force, existence due to cylinder inboard wall pin rod, near the medium of high-speed motion inwall and pin rod bump and have changed its motion state, destroyed original direction of flow, increase the shock between abrasive media and polished material, thereby improved grinding effect.In addition, with smooth barrel, compare, the pin bar structure has avoided a part of abrasive material directly along inner tube wall, to move up and arrive the filter place, has increased the time that abrasive material stops in cylindrical shell, has therefore promoted grinding effect.The pin rod of helical pattern has applied downward power to abrasive media, has increased the density of grinding cylinder bottom abrasive media.
Because the utility model has been applied the lapping mode of dispersion impeller and pin rod simultaneously, the dispersion impeller of usining grinds as moving, usings the pin rod as quiet grinding, and grinding effect is good, wear and tear little, rotated less than the system heating that is driven the abrasive media rotation by the pin rod simultaneously by dispersion impeller drive abrasive media.
Advantage of the present utility model is mainly manifested in grinding efficiency and improves 10%-30% than dispersion disc type sand milling fineness of the same type, has therefore reduced the grinding cycle-index, thereby improves prouctiveness.And particle diameter is more evenly distributed, the distribution equalization is better.The outfit of equipment cost increases little than same category of device, have good economic benefits, is particularly useful for the dye pigment industry.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further.
Fig. 1 is the structure cutaway view of the utility model embodiment.
Fig. 2 is the top view of Fig. 1.
In figure, 1. filter; 2. main shaft; 3. dispersion impeller; 4. grinding cylinder; 5. pin is excellent; 6. charging aperture.
The specific embodiment
As shown in Figure 1 and Figure 2, the present embodiment comprises grinding cylinder 4, main shaft 2, dispersion impeller 3 and some backing pin rods 5, and described grinding cylinder 4 tops are provided with filter 1, and described grinding cylinder 4 belows are provided with charging aperture 6, described dispersion impeller 3 is the radial dispersion impeller, is arranged on main shaft 2; Described pin rod 5 is arranged on the inwall of described grinding cylinder 4 twist, its helical arrangement direction and dispersion impeller 3 direction of rotation.
The course of work of the present utility model is: slip enters in grinding cylinder 4 from the charging aperture 6 of cylinder body bottom, main shaft 2 rotates, the dispersion impeller 3 that drive is fixed on main shaft 2 rotates, and dispersion impeller 3 effectively drives abrasive media and rotates and it is collided mutually, produces and grinds required shearing force.Part abrasive media is thrown to the inwall place of grinding cylinder 4 under the effect of centrifugal force, with the pin rod 5 on grinding cylinder 4, bumps, and the flow direction of abrasive media is changed, and has increased the collision between abrasive media.Slip is finally discharged at filter 1 place.
