Constant-pressure type nanometer homogenizer

Abstract

The invention relates to a constant-pressure nanometer homogenizer, which is applied to the technical field of high-pressure homogenizers, and solves the problems that high-pressure homogenizers are very unstable during working, the flow is limited, existing valve seats and valve cores are poor in wear resistance, causing that the homogenizing effect is poor, and the product cost is increased. A pressure stablizing device includes a crankshaft, a driving piece and a plunger pump group, wherein the crankshaft is provided with three crank throws, the three crank throws are sequentially arranged in the clockwise direction, and the included angle between every two crank throws is 120 degrees, the plunger pump group comprises a connecting rod, a sliding piston rod and a plunger sealing sleeve, one end of the sliding piston rod is fixedly connected with one end of the connecting rod, and the other end of the sliding piston rod is connected into the plunger sealing sleeve in a sealed and sliding mode; the other end of each connecting rod is fixedly connected with the corresponding crank throw, and the driving piece drives the crankshaft to enable the connecting rods on the crankshaft to do reciprocating motion, so that the sliding piston rod is driven to do reciprocating motion in the plunger sealing sleeve; when the homogenizer works, the internal pressure is relatively balanced, and the material crushing and refining effect is improved.

Description

technical field [0001] The invention is applied in the technical field of high-pressure homogenizers, and in particular relates to a constant-pressure nanometer homogenizer. Background technique [0002] The high-pressure homogenizer is also called "high-pressure fluid nano-homogenizer", which can make the material in the suspension state flow through the cavity with a special internal structure at a high speed under the action of ultra-high pressure (up to 60,000 psi) (high-pressure homogenizer Cavity), so that the material undergoes a series of changes in physical, chemical, structural properties, etc., and finally achieves a homogeneous effect. [0003] The existing high-pressure homogenizer has a single-box and single-module structure, that is, a pressure module, and a single-axis motor drives a crankcase and a belt for transmission. The biggest problem with a single module is that there is a pulse between no pressure and the highest pressure. Especially under ultra-hig...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a constant-pressure nano homogenizer, which solves the problem that the pulse is very large under ultra-high pressure, the high-pressure homogenizer is very unstable when working, and the flow rate is limited. In addition, the existing When the valve seat, valve core and material contact surface of the homogenizing valve work at a high pressure above 1000bar, the wear resistance is poor. In actual large-scale production applications, the pressure release distance becomes larger after the homogenizing valve is worn, resulting in poor homogenizing effect , poor product uniformity, waste of materials and increased product cost
