Emulsifying machine

Abstract

The invention relates to an emulsion machine, in particular to a homogenizing emulsion machine, which comprises a homogenizer and an emulsion container. The homogenizer comprises a homogenizing shaft, a rotor and a stator. The homogenizing shaft is connected with the rotor. The geared ring of the stator and the geared ring of the stator constitute a homogenizing mechanism. The homogenizing shaft is provided with a mechanical seal, a slip sleeve, a hydraulic cylinder, and a slip cylinder. The hydraulic cylinder is fixed with the slip cylinder. The slip cylinder slips in the slip sleeve. The slip cylinder is fixed with the homogenizer and slips up and down at the pan bottom of the emulsion container. A cooling chamber is provided, and the mechanical seal is connected with the cooling chamber. Self-circulated cooling solution is arranged inside the cooling chamber with end faces mechanically sealed. The slip cylinder is fixed with the homogenizer and is arranged in the center of the bottom of the emulsion container. The homogenizing emulsion machine provided by the invention is capable of both internal circulation and external circulation, and is provided with the multifunction homogenizer which can be used as a discharging pump, a scavenging pump and a cooling pump. The homogenizing emulsion machine is widely used in the fields of biologic pharmacy, food, items in daily use, chemical engineering, fine chemical engineering and so on.

AI Technical Summary

Problems solved by technology

[0003] At present, there are mainly two types of homogeneous emulsifiers: one is the internal circulation type, which generally adopts internal circulation, upper homogeneous, and tiltable types. The homogenization of the internal circulation mainly relies on internal stirring to circulate the materials in the pot. , the rotor is a propeller-type four-leaf paddle, the stator is outsourced to the rotor, and the gap between the stator and the rotor is generally 0.5mm. Through the high-speed rotation and shearing of the rotor, the material is sucked around the stator or at the bottom along the pot wall of the emulsification container, and passes through the stator and the rotor. The rotor blades are cut and sprayed upwards; the disadvantages are (1) because the homogenizer is a certain distance from the bottom of the emulsification container, the material with high density will sink to the bottom, and it cannot be filled and circulated, which will affect the homogenization effect (2) The circulation mode is that the bottom of the homogenizer is inhaled and ejected in the middle, which should cause the material with a lower density to float, and it cannot be filled and circulated; (3) The shaft end mechanical seal of the homogenizer does not have a cooling system. Unable to withstand high-speed operation for a long time, it usually needs to be stopped for natural cooling within 10 to 20 minutes; (4) Because it circulates in the emulsification container, its production volume is affected, and the general working volume exceeds 500L. The quality emulsification effect begins to decline

[0004] The second is the external circulation, which generally adopts external circulation, lower homogeneity, and non-tilting. The external circulation can better ensure the position of the bottom of the emulsification container and the full homogeneity of the materials in the pot because the material is fully circulated. If the German homogeneous The number of homogenizing heads is large, the shearing is more thorough, and the emulsification effect is ideal; existing problems: (1) This type of equipment is prone to residual materials due to the external circulation pipe, although pumping water can be used for cleaning, but still It is more troublesome; (2) Because it is difficult to realize the tilting type, the discharge is a little troublesome and not thorough, but it reduces the occupied space of the equipment
