Description

Technical Field

[0001] The utility model relates to water-oil mixing equipment, in particular to an emulsifier. Background Art

[0002] As is well known, an emulsifier is to shear, disperse and impact materials through the high-speed rotation of a homogenizing head, making the materials finer and promoting the fusion of oil and water. Emulsifiers are widely used in many cream products such as cosmetics, body wash, sunscreen, etc. Emulsifiers are also used in sauces, juices, etc. in the food industry, ointments in the pharmaceutical industry, petrochemical industry, paint, coatings, inks, etc.

[0003] Currently, the conventional one is a three-stage in-line dispersion emulsifier. For example, CN109999685B is an external fixed three-stage emulsification pump, which adopts an external screw fixing structure relative to the pump cavity of the emulsification tank. While ensuring the reliability of the assembly structure of the emulsification pump itself, it avoids accidents such as material leakage and even screw dropping caused by traditional internal screws, and its working reliability and use safety can be significantly improved. However, as a three-stage emulsification, the contact time between the material and metal is relatively long, and there is a risk of metal contamination. If multiple emulsifications are required in a cycle, the contact time between the material and the metal is even longer. Summary of the Invention

[0004] The purpose of the utility model is to overcome the above deficiencies and provide a bottom-mounted in-line emulsifier. The utility model reduces the contact time between the material and metal, reduces the risk of metal contamination, and is suitable for emulsifying materials with high viscosity.

[0005] The utility model is realized as follows. A bottom-mounted in-line emulsifier includes an emulsifier assembly below the body of the material mixing kettle, and it includes:

[0006] A mounting seat, which is connected to the lower outlet of the mixing kettle, and a main shaft hole is provided in the middle of its lower part, and conical injection holes are provided around the hole;

[0007] A sealing cover, which is fixed below the mounting seat and together with the mounting seat forms a space for emulsifying materials, and a material outlet is provided on the side;

[0008] A main shaft, which passes through the space for emulsifying materials through a sealing member, and a gland is provided at the top;

[0009] A conical spiral impeller, which is sleeved on the upper part of the main shaft and rotates under the drive of the main shaft;

[0010] A centrifugal impeller plus a toothed stator-rotor, which is sleeved on the lower part of the main shaft and is separated from the conical spiral impeller by a spacer on the main shaft.

[0011]

[0012] ​The described bottom-mounted in-line emulsifier has a conical spiral impeller with a continuously decreasing diameter from top to bottom, and the internal shape and size of the mounting seat match the outer shape of the conical spiral impeller.

[0013] The described bottom-mounted in-line emulsifier has the conical spiral impeller mounted on the main shaft and fixed to the main shaft by a gland and screws; the sealing cover is connected and fixed to the mounting seat by screws.

[0014] Compared with the traditional multiple-tooth emulsifiers, the utility model adopts the design of a conical feeding structure, reduces the number of tooth-shaped emulsifiers, thereby reducing the contact between the material and the metal emulsifier, reducing the metal contamination of the material, and being applicable to the emulsification process of high-viscosity materials. During the material emulsification process, through two emulsification effects, if multiple emulsifications are carried out in a cycle, compared with the traditional emulsifier, one-third of the time can be reduced, and the emulsification efficiency is improved. Therefore, this emulsifier can be used as an in-line emulsifier. Its structure is stable and safe, and it is convenient for cleaning and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following further describes the utility model in conjunction with the drawings:

[0019] Please refer to Figure 1 and Figure 2 , a bottom-mounted in-line emulsifier, which includes an emulsifier assembly 1 below the kettle body of the material mixing kettle 2, and it includes:

[0020] A mounting seat 13, which is connected to the lower outlet of the mixing kettle 2, and a main shaft hole is provided in the middle of its lower part, and conical spray holes are provided around the hole;

[0021] A sealing cover 17, which is fixed below the mounting and together with the mounting seat forms a space for emulsifying the material, and a material outlet is provided on the side;

[0022] A main shaft 19, which passes through the space for emulsifying the material through a seal, and a gland 11 is provided at the top;

[0023] A conical spiral impeller 12, which is sleeved on the upper part of the main shaft and rotates under the drive of the main shaft;

[0024] A centrifugal impeller plus a toothed stator and rotor 14, 16, which are sleeved on the lower part of the main shaft and separated from the conical spiral impeller 12 by a spacer 15 on the main shaft.

[0025] As Figure 2 and Figure 3 shown, for a bottom-mounted in-line emulsifier, the diameter of the conical spiral impeller continuously decreases from top to bottom, and the internal shape and size of the mounting seat match the outer shape of the conical spiral impeller.

[0026] For a bottom-mounted in-line emulsifier, the conical spiral impeller is installed on the main shaft and fixed to the main shaft through a gland and screws; the sealing cover is connected and fixed to the mounting seat by screws.

[0027] When the main shaft 19 rotates, it drives the conical spiral impeller 12 to rotate. Under the combined action of the self-gravity of the material in the kettle body and the suction force generated by the rotation of the conical spiral impeller 12, the material enters the conical cavity of the mounting seat 13, and the material is pressurized once. Subsequently, it enters the conical hole designed at the end of the mounting seat 13, and the material is pressurized twice. After that, the pressurized material sprays out from the small hole at the end of the conical hole, forming a spray and a jet. At this time, the material is emulsified once. The material after the first emulsification flows through the high-shear emulsifier composed of a stator 14 and a rotor 16 for secondary emulsification. After the material is emulsified twice, it flows out from the discharge port on the sealing cover 17. The emulsified material can be refluxed to the kettle body according to the process requirements for multiple cycles of emulsification.
