Abstract

The utility model discloses an injection-type stepless extendible electric stirrer which is used in laboratories. A poker is divided into an upper shaft [6] and a lower shaft [9]. The lower shaft and a nozzle [11] can be drawn synchronously. An extension tail tube [16] can increase the regulating range of stretching. When the stirrer works, objects are inhaled from a diversion hole for diversion of a bottom shaft [15]. When an electric motor drives a blade wheel [14] of the poker and a flow distribution plate [12] rotate in high speed, the objects in the nozzle are given the pressure energy and the velocity energy. The objects are jetted outward along a spray hole [13] at the same time of stirring and mixing. The objects are mixed again in a container, which makes larger multiphase substances of which specific gravity and degree of viscosity are quite different obtain better mixing effect under the conditions of low liquid level and low phase, or high liquid level and high phase.

Description

Injection-type stepless extendible electric stirrer

What the present invention relates to is that the stepless stretching electric mixer of formula is carried in a kind of spray, especially for a kind of mixing plant of laboratory.

Existing electric mixer is directly to drive the puddler that replaceable difformity stirring-head is housed by motor to rotate, and object is stirred.This shows that this agitator just stirs object by the rotation of stirring-head, therefore when the heterogeneous object that differs bigger to proportion and viscosity stirs, each phase object is to rotate between level separately basically, mutual diffusion is restricted, poor to the mixed effect that makes object, the mutual contact area of each phase material is little, the chemical reaction weak effect, and mixing velocity is slow.The length of the puddler of this agitator is fixing nonadjustable simultaneously, thereby when being used for stirring the object of differing heights, has brought a lot of inconvenience for installation and adjustment work.

The objective of the invention is to design a kind ofly can carry out extracting, spray diffusion object, rotation is stirred, and the stepless stretching electric mixer of formula is carried in the spray of adjusting that can stretch.

Spray is carried the stepless stretching electric mixer of formula and is driven the puddler rotation by motor, puddler divides goes up axle and lower shaft two parts, be installed with a flow distribution plate on the lower shaft axostylus axostyle, it is the impeller that 10～45 ° blade is formed by a slice or several pieces its lift angles that the bottom is installed with one, a pair of rolling bearing is housed in the bearing holder (housing, cover), bearing holder (housing, cover) is equipped with a mozzle outward, can bore a row or number row on the mozzle circumference as required, every row has one or several spray-hole, be drilled with several through holes on the lower shaft, be installed with two bayonet locks on the cylindrical, be used for respectively with mozzle and flexible tail pipe on the bayonet lock groove link, flexible tail pipe is that sleeve pipe that can be nested against one another is formed by the number joint, and bearing holder (housing, cover) and mozzle and last between centers seal with sealing ring respectively.Parts such as last axle, lower shaft, mozzle, lower shaft, flexible tail pipe, bearing holder (housing, cover), impeller, flow distribution plate all are that the materials processing with corrosion-resistant, anti-solvent, heatproof forms, and bottle stopper is to process with polytetrafluoroethylene (PTFE).

Accompanying drawing is the structural representation that the stepless stretching electric mixer of formula is carried in spray.Frame (1), clamping device (2), motor (3), connecting shaft cover (4), bottleneck clamping device (5), last axle (6), a bottle stopper (7), bearing holder (housing, cover) (8), lower shaft (9), mozzle (10), flow distribution plate (12), spray-hole (13), impeller (14), lower shaft (15), flexible tail pipe (16), sealing ring (11), (17).

Divide upward axle (6) and lower shaft (9) two parts with reference to the accompanying drawing puddler, the axle of last axle and motor (3) is connected into one by connecting shaft cover (6), lower shaft is installed in the hole of axle, with last axle be matched in clearance, can in last axle, slide up and down, one side of lower shaft is processed with a plane, the rotating torque of last axle is to transmit by the contract piece that embeds this plane and last between centers, be installed with a flow distribution plate (12) with the concordant place of spray-hole (13) on the lower shaft axostylus axostyle, impeller (14) is fixedly mounted on the lower end of lower shaft, by a slice or several pieces, lift angle is that 10～45 ° blade is formed, top on the lower shaft (15) is to be used for supporting lower shaft, lower shaft and mozzle (10) are to be connected into one by bayonet lock, mozzle and bearing holder (housing, cover) (8) are matched in clearance, can slide up and down along bearing holder (housing, cover), like this when mozzle moves down, because lower shaft and mozzle join together, lower shaft also moves down, and lower shaft falls by deadweight, when mozzle moves up, top will the top on the lower shaft on the lower shaft, thereby mozzle and lower shaft can move up and down synchronously, thereby can guarantee that flow distribution plate is mutually concordant with the spray-hole on the mozzle, to reach the purpose of stepless stretching adjustment.In order to increase the adjustable range of stretching, design has the flexible tail pipe (16) of a joint in addition, and flexible tail pipe is to connect all-in-one-piece by bayonet lock with lower shaft, when container is more shallow, it can be unloaded down.Utilize the tension force of sealing ring (11), can stop the mozzle of adjusting the use location to fall automatically.The adjustment of mozzle and flexible tail pipe is according to the liquid level of differing heights and practises physiognomy and adjust.Bearing holder (housing, cover) and mozzle and last between centers are used sealing ring (11) respectively, (17) seal, to prevent that object is to external leakage, having formed one like this in the mozzle can be for stirring the inner chamber that object is used, when the driven by motor puddler rotates at a high speed, impeller is rotation at a high speed in mozzle, object is stirred, promote object by the blade lift that turning moment produced, and give the interior object of mozzle with pressure energy and speed energy, object is under the effect of these two kinds of energy and flow distribution plate, from spray-hole (13) to around eject, resistance when spraying for reducing object, utilize jet power that object is rotated stirring, spray-hole is designed to an inclined hole, its axis and mozzle internal diameter are tangent, object constantly sucks from the bottom of agitator like this, mix, spray, mix again, make object can on three dimensions, do the high speed shuttling movement, finish the mixing of heterogeneous object and stir.

Because this agitator mainly is to be used for chemical test usefulness, thereby mozzle, bearing holder (housing, cover), to go up parts such as axle, lower shaft, flow distribution plate, impeller, lower shaft, the tail pipe that stretches all be to process with 1 chromium, 18 nickel, 9 titanium stainless steels.

The advantage of this agitator is to use to adjust easily, only needs during use to transfer in advance as required The length of whole well flexible tail pipe or mozzle. Because during this agitator work, can make and do the high-speed circulating motion in the three dimensions of object in container, make contact area increase between each phase object, viscosity reduces, and speed and reaction efficiency that heat transmits all increase to some extent, even viscosity and proportion differ mutually material of bigger each, in the situation of low liquid level, low phase place or high liquid level, high phase place, also can obtain better mixed effect.
