Abstract
The utility model provides a double-layer tooth-type high shearing strong dispersion wheel used on a dispersion machine, which aims to solve the technical problems that the existing dispersion wheel used in the dispersion machine has non-ideal dispersing and shearing effects and poor homogenizing effect so as to seriously influence the production efficiency because the existing dispersion wheel has simple structure, small axial sectional area, low shearing and covering quantity, material splashing phenomenon generated during high-speed running, and low shearing intensity to the materials in a tank. The utility model has the technical scheme that an upper layer and a lower layer of blades are connected by a screw bolt of which both ends are provided with screw threads, and are fixed by nuts. Accordingly a plurality of connecting screw bolts are evenly distributed on the round blades; teeth staggered upwards and downwards are arranged on the circumference of the blades of each layer. Due to the adoption of the double-layer tooth-shaped blades, the axial area is equivalent to several times of that of a single blade type impeller so as to ensure that the materials can not splash during high-speed running and to improve the shearing, dispersing and homogenizing effects. The utility model is suitable for being used in the dispersion machines.
Description
[technical field]
The utility model relates to the dispersion wheel in the dispersion machine that liquid and solid powder are mixed, dissolve and disperses.
[background technology]
Dispersion machine be to two or more liquid and solid powder mix, the equipment of dissolving, homogenizing and dispersion.Such as producing building coating, paint, printing ink, dyestuff and cosmetics etc., all need dispersion machine.Dispersion wheel is the vitals in the dispersion machine, play effects such as dispersion, shearing and homogenizing, so it has determined the performance of dispersion machine.Employed dispersion wheel in the dispersion machine mainly adopts the one chip impeller at present.Material in the dispersion tank is under the effect of impeller blade face anterior angle, with wheel rotation, and produce by the motion of dispersion tank periphery to the upset of dispersion tank center.But because this blade wheel structure is simple, axially basal area is little, and it is low to shear topped amount, and is also very low to material cutting intensity in the jar, and produces the excessive spatter phenomenon when running up.Therefore its dispersion, shear effect are very undesirable, and homo-effect is poorer, has a strong impact on production efficiency.Also have the minority dispersion machine to adopt slurry formula impeller or frame impeller etc., during these dispersion wheels only are adapted at, do material under the low-speed conditions and stir and use.
[summary of the invention]
The purpose of this utility model be to provide a kind of shear strength height, dispersion force strong, be adapted at the double-deck profile of tooth high shear brute force dispersion wheel that uses high-speed condition under.
The purpose of this utility model is achieved in that up and down two-layer blade connects with the threaded double-screw bolt of double headed roller, fixes with nut, and such connection double-screw bolt has several, is distributed on the circular blade, on the circumference of every layer of blade, staggered up and down tooth is arranged.
The utility model compared with prior art because it adopts double-deck profile of tooth blade, long-pending several times of being equivalent to the one chip impeller of its axial cross section have guaranteed that material does not splash down running up, and has improved shearing, dispersion and homo-effect; Moreover, several connecting rods also to material shear, dispersion and homogenizing, so the utility model is to the effect highly significant of shearing, dispersion and the homogenizing of material.
[description of drawings]
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is a front view of the present utility model.
Fig. 2 is the cutaway view of Fig. 1 along the B-B line
Fig. 3 is the cutaway view of Fig. 1 along the A-A line.
[specific embodiment]
The threaded double-screw bolt 4 of two-layer up and down blade 1 usefulness double headed roller connects, and fixing with nut 3, such connection double-screw bolt 4 has eight, is distributed on the circular blade, on the circumference of every layer of blade, staggered up and down tooth 2 is arranged.In order to improve the thinning effect of material, preceding basil β and malleation angle γ are arranged, on each tooth referring to Fig. 2.It adopts double-deck profile of tooth blade, and its axial area is equivalent to several times of one chip impeller, has guaranteed that material does not splash under running up, and has improved shearing, dispersion and homo-effect; Moreover, several connecting rods also to material shear, dispersion and homogenizing, so the utility model is to the effect highly significant of shearing, dispersion and the homogenizing of material.
