Description
Technical field
The utility model relates to a kind of chemical experiment equipment, is specifically related to a kind of laboratory stirrer.
Background technology
In the prior art, laboratory stirrer is made up of support, horizontal connecting rod, motor, stirring rod and stirrer paddle, support is made up of base and the vertical rod that is connected on base, laterally the top of connecting rod is connected with vertical rod, motor is arranged at the end of horizontal connecting rod, the power output shaft of motor is connected with stirring rod downwards, and stirrer paddle is fixedly connected on the lower end of stirring rod.
But because stirrer paddle is fixedly connected with stirring rod, non-dismountable, the stirrer paddle of ad hoc structure can not be applicable to multiple container not of uniform size, it can not make the material in larger container fully be stirred.Meanwhile, because high solid-liquid ratio material required stirring dynamics in process of the test is larger, stir inequality can cause material mass transfer, conduct heat inhomogeneous.
Utility model content
The purpose of this utility model is the deficiency existing in order to overcome prior art, and a kind of rational in infrastructure, laboratory stirrer that can be applicable to multiple container not of uniform size is provided.
The utility model is achieved through the following technical solutions: a kind of laboratory stirrer, comprise support, laterally connecting rod, motor and stirring rod, support is made up of base and the vertical rod that is connected on base, laterally the top of connecting rod is connected with vertical rod, motor is arranged at the end of horizontal connecting rod, the power output shaft of motor is connected with stirring rod downwards, also comprise stirring-head, this stirring-head comprises circular spiral shell head and is arranged at the multiple stirrer paddles formations on this spiral shell head, the lower end of described stirring rod is provided with external screw thread, the middle part of described spiral shell head is provided with tapped blind hole, described stirring-head is by tapped blind hole and externally threaded being connected in the lower end of described stirring rod.
In described stirring-head, on the excircle of described spiral shell head, be provided with uniformly three fixing stirrer paddles, the top of fixing stirrer paddle is fixedly connected with spiral shell head, the end of fixing stirrer paddle is provided with connecting hole, and three are provided with being connected at the end of described fixing stirrer paddle of the connecting hole of the Foldable mixing blade of connecting hole by the connecting hole of screw and fixing stirrer paddle, Foldable mixing blade.
Described fixing stirrer paddle, described Foldable mixing blade are crescent, and a recessed side of described fixing stirrer paddle and a recessed side of described Foldable mixing are facing each other.
The beneficial effects of the utility model are: of the present utility model rational in infrastructure, can be applicable to multiple container not of uniform size.The utility model can be used for, in the lab scale unit operations of laboratory, material evenly being mixed, and prevents material precipitation.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the structure for amplifying schematic diagram of stirring-head part.
In the drawings: 1-base; 2-vertical rod; The horizontal connecting rod of 3-; 4-motor; 5-stirring rod; 6-stirring-head; 7-spiral shell head; 8-fixes stirrer paddle; 9-Foldable mixing blade.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As Fig. 1, shown in Fig. 2, a kind of laboratory stirrer, comprise support, laterally connecting rod 3, motor 4, stirring rod 5 and stirring-head 6, support is made up of base 1 and the vertical rod 2 that is connected on base 1, laterally the top of connecting rod 3 is connected with vertical rod 2, motor 4 is arranged at the end of horizontal connecting rod 3, the power output shaft of motor 4 is connected with stirring rod 5 downwards, stirring-head 6 comprises circular spiral shell head 7 and is arranged at the multiple stirrer paddles formations on this spiral shell head 7, the lower end of stirring rod 5 is provided with external screw thread, the middle part of spiral shell head 7 is provided with tapped blind hole, stirring-head 6 is by tapped blind hole and externally threaded being connected in the lower end of stirring rod 5.
In the utility model, adopt removable stirring-head 6, user can, according to the difference of material properties, change the stirring arm of different structure.This structure is convenient to dismounting, is installed, easy to operate.
As shown in Figure 2, in stirring-head 6, on the excircle of spiral shell head 7, be provided with uniformly three fixing stirrer paddles 8, the top of fixing stirrer paddle 8 is fixedly connected with spiral shell head 7, the end of fixing stirrer paddle 8 is provided with connecting hole, and three are provided with being connected at the end of fixing stirrer paddle 8 of the connecting hole of the Foldable mixing blade 9 of connecting hole by the connecting hole of screw and fixing stirrer paddle 8, Foldable mixing blade 9.
Fixing stirrer paddle 8, Foldable mixing blade 9 are crescent, and a recessed side of fixing stirrer paddle 8 and a recessed side of Foldable mixing are facing each other.
Finally should be noted that; above content is only in order to illustrate the technical solution of the utility model; but not restriction to the utility model protection domain; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or be equal to replacement, does not all depart from essence and the scope of technical solutions of the utility model.
