Disclosure of Invention
The utility model aims at solving the problems in the prior art, and provides a shearing emulsion pump with simple structure and good sealing effect.
The purpose of the utility model can be realized by the following technical proposal: the utility model provides a shear emulsification pump, including work cavity and frame, it has the inlet pipe to link firmly at the work cavity front end, the discharging pipe has been linked firmly at the work cavity lateral part, wear to be equipped with the transmission shaft in the frame and the inner of transmission shaft stretches into in the work cavity, a serial communication port, the axle sleeve has set firmly on the transmission shaft, be equipped with mechanical seal between axle sleeve and work cavity rear end inner wall, be equipped with first shear emulsification head, second shear emulsification head and third shear emulsification head in proper order in the transmission shaft inner outside-in, be equipped with the impeller and the impeller sets firmly on the axle sleeve between the interior terminal surface of third shear emulsification head and work cavity rear end.
In the above shear emulsification pump, the impeller is located below the discharge pipe.
Compared with the prior art, the utility model has the advantages of it is following: the shearing emulsifying pump is characterized in that an impeller is arranged between a third shearing emulsifying head and an inner end face at the rear end of a working cavity, the impeller is fixedly connected with a transmission shaft through a shaft sleeve, when a material enters a cavity in a narrow space in the working cavity from a feeding pipe, the transmission shaft is driven by a motor to rotate so as to drive the first shearing emulsifying head, the second shearing emulsifying head, the third shearing emulsifying head and the impeller to synchronously rotate, the impeller and the shearing emulsifying head synchronously rotate, so that the emulsified material discharged by the third shearing emulsifying head can be rapidly discharged from a discharge pipe under the high-speed rotation action of the impeller, and the impeller is close to the inner end face at the rear end of the working cavity, thereby making up a gap between the third shearing emulsifying head and the rear end of the working cavity, preventing the emulsified material from flowing into a mechanical seal from an opening at the rear end of the working cavity, and better protecting the mechanical seal, the phenomenon of leakage is avoided.

Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1, the shearing emulsifying pump comprises a working cavity 1 and a machine base 2, a feeding pipe 3 is fixedly connected with the front end of the working cavity 1, a discharging pipe 4 is fixedly connected with the side part of the working cavity 1, a transmission shaft 5 penetrates through the machine base 2, the inner end of the transmission shaft 5 extends into the working cavity 1, a shaft sleeve 6 is fixedly arranged on the transmission shaft 5, a mechanical seal 7 is arranged between the shaft sleeve 6 and the inner wall of the rear end of the working cavity 1, a first shearing emulsifying head 8, a second shearing emulsifying head 9 and a third shearing emulsifying head 10 are sequentially arranged at the inner end of the transmission shaft 5 from outside to inside, an impeller 11 is arranged between the third shearing emulsifying head 10 and the inner end face of the rear end of the working cavity 1, the impeller 11 is fixedly arranged on the shaft sleeve 6, and the impeller 11.
The shearing emulsifying pump is characterized in that an impeller 11 is arranged between a third shearing emulsifying head 10 and an inner end face at the rear end of a working cavity 1, the impeller 11 is fixedly connected with a transmission shaft 5 through a shaft sleeve 6, when a material enters a cavity in a narrow space in the working cavity 1 from a feeding pipe 3, the transmission shaft 5 is driven by a motor to rotate so as to drive a first shearing emulsifying head 8, a second shearing emulsifying head 9, a third shearing emulsifying head 10 and the impeller 11 to synchronously rotate, the material is rapidly sucked to a gap between the shearing emulsifying head and the inner wall of the working cavity 1 through three-stage operation of the first shearing emulsifying head 8, the second shearing emulsifying head 9 and the third shearing emulsifying head 10 by the shearing emulsifying head rotating at a high speed, and the material is subjected to strong mechanical and hydraulic shearing at the gap between the shearing emulsifying head and the inner wall of the working cavity 1 due to strong kinetic energy caused by high circumferential linear velocity and high frequency mechanical effect generated by the rotation of the shearing emulsifying head, Centrifugal extrusion, liquid layer friction, impact tearing, turbulent flow and other comprehensive effects, so that incompatible solid phase, liquid phase and gas phase are instantaneously, uniformly and finely dispersed and emulsified under the combined action of a corresponding mature process and a proper amount of additives, and are subjected to strong shearing dispersion action through high-frequency circulation reciprocating, and finally, a stable high-quality product is obtained and is discharged from the discharge pipe 4. Simultaneously, set up impeller 11 in discharging pipe 4 below, because impeller 11 and shearing emulsifying head are synchronous revolution, this makes the material after the emulsification of shearing emulsifying head 10 exhaust third can discharge from discharging pipe 4 under the high-speed rotatory effect of impeller 11 fast, impeller 11 is close to in the interior terminal surface of work cavity 1 rear end simultaneously, thereby compensatied the clearance between third shearing emulsifying head 10 and the work cavity 1 rear end, make the material after the emulsification can not flow into to mechanical seal 7 from the opening part of work cavity 1 rear end, thereby better protection mechanical seal 7, avoid appearing the phenomenon of revealing.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
