Abstract

The utility model provides a colloidal mill head for processing colloidal materials. The rotor of the colloidal mill head comprises a frustum or two to three segments of frustums which are assembled and have different taper, and the stator also comprises a conical cavity or two segments of conical cavities which are assembled and have different or the same taper. The mill head can bite into the materials of coarse particles, and the process capability is great; compared with an existing colloidal mill, the processed particles are finer; the service life of the mill head is long.

Description

Ultramicro-disintegrating colloid mill head

The utility model relates to a kind of parts of colloid material-pulverizing device, is a kind of bistrique of ultramicro grinding colloid mill.

Existing colloid mill bistrique mainly is made of the rotor of a truncated cone shape and a stator that has the truncated cone chamber that cooperates with rotor, and has the tooth lapping that can shear each other respectively on the conical surface of rotor and stator.Its operation principle is: different taperings is made with the cone of rotor in the awl chamber of stator, promptly allow stator and rotor form the certain included angle gap at bistrique feed end (miner diameter end of the truncated cone), so that utilize this gap coarse fodder particle of nipping, and relatively rotating along with stator and rotor, the minimum clearance place that the coarse fodder particle is ground gradually cooperate with rotor into stator makes it to be ground into fine particles.But, because this bistrique is to realize by the formed nip angle of different taperings by between stator and rotor to nipping of coarse fodder, therefore, if want that the coarse fodder that makes this bistrique can eat larger particle must enlarge its nip angle, certainly will to cause carrying out between stator and rotor the shortening of fine lapping section like this, this not only can influence its Grinding Quality, and can influence the working life of rotor.Equally,, can reduce nip angle again, the granularity of nipping of Coarse Aggregate is restricted if want to make fine grinding section lengthening.

The purpose of this utility model provides a kind of colloid mill bistrique of ultramicro grinding, and it can not only process the particle trickleer than common colloid mill, and the coarse fodder of the larger particle of can also nipping, and can improve the work quality of bistrique.

The purpose of this utility model is achieved in that the rotor of this colloid bistrique is to constitute by a truncated cone or by the truncated cone through the different taperings of 2-3 section of assembling, and its stator also is to constitute by a cone cavity or by the awl chamber through 2 sections similar and different taperings of assembling.

Narrate embodiment according to accompanying drawing below.

Fig. 1 is the grinding wheel head structure schematic diagram of the stator that constitutes of the rotor that constitutes of the truncated cone by two sections different taperings and two sections awl chambeies.

Fig. 2 is the rotor structure schematic diagram that constitutes by three sections.

Fig. 3 is the structural representation that is made of stator the awl chamber of two sections different taperings.

Fig. 4 is the grinding profile of tooth structural representation that is positioned on the stator and the rotor conical surface.

As shown in Figure 1: the rotor of this colloid mill bistrique is to cooperate the location to be assembled together by the I level rotor 1 and the II level rotor 2 usefulness faces of cylinder, constitutes its rotor with the truncated cone that forms by two sections different taperings.The rotor that will assemble again with key 3 and screw 4 is installed on the main shaft 5 with accurate cooperation.I level stator 6 and II level stator 7 location are assembled together, and are constituted its stator with this by two sections identical awl chambeies of tapering.In the junction cylindrical groove of stator 6 and stator 7, put O-ring seal.I level rotor 1 and I level stator 6 its taperings differ bigger, to form the bigger feed end of opening, and forming the cross section on the conical surface separately respectively is triangle or square roughing profile of tooth, makes in its bistrique of bulky grain coarse fodder being nipped, so that can enter finishing workshop section smoothly.The cone of II level rotor 2 and II level stator 7 is identical with the tapering in awl chamber, and has the negative rake serration on the conical surface separately respectively, so that material is finished retrofit in this section.The processing granularity of retrofit section then realizes by the gap △ that regulates 7 of rotor 2 and stators.

The truncated cone that rotor 8 shown in Figure 2 has three sections different taperings constitutes, and between per two sections truncateds cone the such locating surface of Fig. 1 is arranged all.Stator 9 is overall structures, still has cannelure on the cylindrical, is provided with sealing ring in the groove.Between rotor and stator from top to bottom the tapering of the truncated cone by different taperings change, and formed the machining gap that reduces gradually with boring between the chamber at the truncated cone.

Bistrique shown in Figure 3, its rotor 10 are all-in-one-piece big tapering rotor.And stator is to be made of the awl chamber of I level stator 11 with II level stator 12 these two sections different taperings, because of the tapering of the tapering of II level stator 12 and rotor 10 identical, and I level stator 11 taperings are less than the tapering of rotor 10, so between the rotor and stator after the assembling, the gap of its feed end is bigger.Because the tapering of the bistrique discharge end of this kind structure is bigger, centrifugal action is strong, is suitable for processing sticky material.

Shown in Figure 4 is the negative rake profile of tooth that is applied in rotor 13 and the stator 14 finishing workshop sections.So-called negative rake is the definition of quoting on the metal cutting tool, and wherein α is the negative rake on the rotor 13, and β is the negative rake of stator 14.On the conical surface of the rotor of finishing workshop section and stator, adopt the negative rake tooth-shape structure respectively, can make particle be easy to get into to be squeezed between the conical surface and grind, thereby obtain more meticulous processing granularity.

The utility model is because of adopting the different tapering truncateds cone and awl chamber respectively between the rotor of bistrique or stator, not only can make the feed end of bistrique produce bigger opened gap, so that make the bistrique bigger coarse fodder of particle of nipping, improve the working ability of this mill and adapted to the ability of processing various materials, and make its rotor identical again with the tapering of stator in finishing workshop section, the fine finishining that had so both changed original bistrique only is created on the clothoid, its defective that grinding material time is short, particle is thick, the service life of having improved bistrique again.Especially adopt the negative rake tooth-shape structure again in finishing workshop section, will further improve the fine finishining granularity of this mill.
