Abstract

The utility model discloses a fluid mixer, belonging to a static fluid mixer. The fluid mixer is composed of a casing, a plurality of switching baffle groups, a plurality of baffling baffle groups, and a guide rod. The switching baffle groups and the baffling baffle groups are arranged in series, and each baffle is fixed on the guide rod by a positioning screw nut. The utility model has the advantages of simple structure, easy manufacturing and small size. The fluid mixer can be used by directly installing on the pipeline. The fluid mixer is widely applied to fluid mixing, in particular to the quick cooling process in the process of preparing lubricating grease.

Description

Fluid mixer

The utility model belongs to fluid mixing apparatus, and more particularly, it is to be used for preparing the cooling of lubricating grease process soap dispersion and the mixing of liquid stream, belongs to the static fluid blender.

For solving the mixing and the dispersion of liquid-liquid, the introduction of existing multiple static mixer.SMV type (the F.Stroiff of Switzerland Sulzer company for example, Sulzer Technical Review, 59 ［ 3 ］, 108,1977), the H1 type of Japan Dong Li Co., Ltd. (gloomy island Thailand, Song Cunhui, the youth. chemical devices, 2 ［ 8 ］, 35,1979), the KNS type of the Kenics company of the U.S. (J.M.Smith, The Chemical Engineer, ［ 338 ］, 827,1978), these static mixing all are that to be used for viscosity little, and the liquid of no phase change-liquid mixes and disperses, need to take place from molten mass to gelatinous phase transition process at refrigerating work procedure for preparation lubricating grease, the structure of this class static mixer is just inapplicable.For solving the fluid mixing that the generation of preparation lubricating grease changes mutually, " dispersion of TK type continous way, the mulser " of the eighties Japan Tokushu Kika Kogyo K.K development, but, this device structure complexity, difficulty of processing is big, need a kind of direct-connected variable speed electric motors, particularly drive agitator that is used as power, and the volume of equipment is also bigger.

The purpose of this utility model provides a kind of simple in structure, and is easy to operate, good mixing effect and can be used for the static mixer that liquid stream that lubricating grease chilling operation changes mutually mixes.

Characteristics of the present utility model are that blender comprises housing, reversible deflector group, hydraulic barrier group, guide rod.Hydraulic barrier group and reversible deflector group arranged in series are staggered between the baffle plate of hydraulic barrier group and between the baffle plate of reversible deflector group, and all baffle plates are all located and are fixed on the guide rod with positioning screw cap, and the housing two ends connect with flange.After different fluids is sent into blender, dam with concentrated through one group of hydraulic barrier earlier, and tentatively mixed, again by one group of reversible deflector, make material be divided into multiply and repeatedly commutate, and then, dam concentrated through repeated multiple times like this by another group hydraulic barrier group, disperse commutation, reach the purpose that abundant mixing disperses.In the chilling operation of preparation lubricating grease, hot and cold oil is fully mixed at short notice, mass-and heat-transfer is even, thereby has improved the chilling effect.

Further set forth characteristics of the present utility model below in conjunction with accompanying drawing.

Fig. 1 is the schematic diagram of blender of the present utility model.

Fig. 2 is the reversible deflector cutaway view.

Fig. 3 is the hydraulic barrier cutaway view.

Blender shown in Figure 1 comprises housing (1), reversible deflector group (2), hydraulic barrier group (3), guide rod (5).Housing (2) two ends are associated with flange (6).At least 6 baffle plates of every group of reversible deflector, have 3 groups at least, first reversible deflector fin closely contacts with the floor of second baffle plate, 5～10 millimeters of one side square openings of second baffle plate of contact position distance, other baffle plates mode are according to this arranged, and every reversible deflector is fixed on the guide rod (5) with positioning screw cap (4); Each group hydraulic barrier at least 4 hydraulic barrier has 4 groups at least, and every hydraulic barrier is staggered, the baffle plate square opening of every group odd number and even numbers point-blank, every baffle plate is fixed on the guide rod (5) with positioning screw cap (4).Hydraulic barrier group and reversible deflector group arranged in series, and housing (1) two ends are hydraulic barrier group (3).Last piece baffle plate of hydraulic barrier group and first baffle plate of reversible deflector group are arranged with the optional position, touch but be critical to connect airtight.

Reversible deflector shown in Figure 2, it is one thick 1～1.5 millimeter garden shape metallic plate, its diameter is identical with pipeline diameter by logistics, have at least 6 finned square openings on the baffle plate, be about to baffle plate and be divided into some equal portions (as 60 ° of one equal portions), open one " L " shape otch by the baffle plate outer along centerline direction, fin is dug and vertical from straight otch with the plate face, form the rectangular hole (7) that an end has fin (9), the length in hole: wide is 4～6:1, the straight otch end points and the distance in the center of circle are less than 1/4 of baffle plate radius, and remainder is floor (8), and fin can play the effect of support.The diameter in its centre hole and the diameter of guide rod coupling.

Hydraulic barrier shown in Figure 3 is a thick circular metal plate of 1～1.5 millimeter, its diameter is identical with reversible deflector, have 4 finned square openings on the baffle plate at least, be about to baffle plate and be divided into some equal portions, open one " ㄇ " shape otch apart from the center of circle less than 1/4 place of baffle plate radius at each equal portions, fin is dug and vertical by the transverse incision of upside with the plate face, form the square opening (7 ') that an end has fin (9 '), hole wide: length is 1～1.5:1, remainder is floor (8 '), and fin can be played a supporting role.Its centre bore dia and guide rod diameter coupling.

Guide rod (5) is a threaded rod, and reversible deflector and hydraulic barrier on it, form an integral body with fixed by nut.

Blender is by following method work.After different logistics enter blender by certain speed, at first go into first group of first hydraulic barrier, flow out by first baffle plate square opening, impact is on second floor, most of logistics is impacted on the 3rd floor by second square opening again, the dispersion of so repeatedly damming, logistics flows out from the square opening of last piece hydraulic barrier then, enter the reversible deflector group by first reversible deflector square opening, contact with fin when logistics enters square opening, after the flow direction is obstructed, flow into second baffle plate square opening again, so repeatedly after the commutation, enter second group of hydraulic barrier group again.Repeatedly dam concentrated and the commutation dispersion by above-mentioned, can reach well-mixed purpose.

The utility model has following advantage:

Because blender of the present utility model can make different logistics through the commutation of repeatedly share split turbulent flow, baffling is concentrated, thereby logistics is mixed, good mixing effect; Chilling operation for the preparation of the bigger lubricating grease of viscosity, obtain good chilling effect, this is because hot and cold oil can fully be mixed, keep its mass-and heat-transfer even, and the chilling final temperature is controlled easily, can by regulating the cold oil amount, meet the requirements of final temperature, to obtain the soap fiber of needed different structure; Because blender is to work under static state, itself do not need power to drive, therefore save energy consumption; Of the present invention simple in structure, handling ease, volume is little, can be directly installed on the pipeline to use, and operates more convenient.
