Abstract

The utility model relates to a pressure stabilizing homogenizer which mainly comprises a motor, a crankshaft, a plunger pump, a homogenizing block, a feed inlet, a discharge port, a one-way valve, a filter, a homogenizing valve and a pressure regulator. The filter is arranged in front of the homogenizing valve of the pressure stabilizing homogenizer, and larger blocks such as broken sealing gaskets in the materials pass through the filter and then enter into the homogenizer, so that the homogenized materials do not block the homogenizing valve at the working state, therefore, the pressure in the homogenizer is relatively stable, and a purpose of automatically stabilizing the pressure of the homogenizer is achieved. The pressure stabilizing homogenizer provided by the utility model is simple to operate and low in cost.

Description

The voltage stabilizing homogenizer

Technical field the utility model relates to pulverizes emulsification machinery apparatus field, particularly a kind of voltage stabilizing homogenizer.

Background technology in the prior art; homogenizer is by electric control gear; power set; plunger displacement pump; the homogeneous piece; charging aperture; discharging opening; check valve; homogenizing valve and pressure regulator are formed; this homogeneous function is with fluent material or solid-liquid composite material dispersion and emulsion and pulverizing; during work; the capital is at filter of the front of homogenizer series connection; bigger block in fluent material or the solid-liquid composite material is filtered out; but when hyperpressure is worked; the homogenizer sealing gasket is broken easily; the sealing gasket of plunger displacement pump particularly; broken sealing gasket enters in the material, stops up in running order homogenizing valve, and the pressure in the homogenizer is sharply raise; the safety value that surpasses homogenizer easily; causing danger, is to adopt over-pressure safety device to solve at present, but the unstable properties of over-pressure safety device when hyperpressure is worked; when not surpassing setting pressure; the material problem appears easily leaking, when surpassing setting pressure, and the also state that can occur not opening.

Utility model content the purpose of this utility model will overcome above-mentioned defective exactly, and a kind of new voltage stabilizing homogenizer is provided.

The technical solution of the utility model is: the voltage stabilizing homogenizer is mainly by starter, motor, bent axle, plunger displacement pump, the homogeneous piece, charging aperture, discharging opening, check valve, filter, homogenizing valve and pressure regulator are formed, power supply connects starter and motor, connect by bent axle between motor and the plunger displacement pump, plunger displacement pump is made up of plunger and plunger cavity, the plunger cavity of plunger displacement pump is positioned at the homogeneous piece, also has pressure chamber in the homogeneous piece, charging aperture and discharging opening, charging aperture, plunger cavity, pressure chamber and discharging opening communicate successively, check valve all is installed between charging aperture and the plunger cavity and between plunger cavity and the pressure chamber, filter is installed in the pressure chamber, homogenizing valve is installed in the position that pressure chamber is connected with discharging opening, filter bits has hermetically-sealed construction between filter and the homogenizing valve between check valve and homogenizing valve.Filter is network structure or orifice plate shape structure, and filter can be made planar shaped, taper, elongate tubular, and wherein the filter area of elongate tubular structure is big, anti-obstruction.According to the characteristics of material, filter can be the individual layer network structure, also can be multiple layer network structure, general 1-5 layer.According to the characteristics of material and the size of pressure, the order number of strainer screen is selected arbitrarily between the 30-300 order, order number commonly used is at the 40-160 order, what integrated cost was lower is the 50-120 order, select the 120-180 order when requiring pressure more stable, when selecting the filter screen more than 200 orders for use, the pre-treatment cost of material is very high, is applicable to high value-added product.During the work of voltage stabilizing homogenizer, the energising of power-on switch, the starter actuating motor, motor moves reciprocatingly by the plunger that bent axle drives plunger displacement pump, in material aspirated into plunger cavity from charging aperture, under the cooperation of check valve, material is squeezed in the pressure chamber of homogeneous piece, aspirate so repeatedly and push, make material form high pressure in pressure chamber, material earlier by cancellated filter, filters out the thicker block in the material in pressure chamber, material after the filtration enters homogenizing valve and carries out homogeneous, finishes the homogeneous micronization of material is handled.Homogenizer is handled the homogeneous micronization of material and is finished by homogenizing valve, and cardinal principle has two, and the one, material passes through the valve seat of homogenizing valve and the extruding in the gap between the push rod; The 2nd, material passes through homogenizing valve from the high pressure conditions in the pressure chamber of homogeneous piece, moment enters low-pressure state, utilizes void effect to finish material dispersed emulsification and pulverizing, and the pressure difference before and after the homogenizing valve is more big, void effect is more strong, and the effect of dispersion and emulsion and pulverizing is more good.Pressure before the homogenizing valve is the pressure of material in pressure chamber, and the pressure behind the homogenizing valve is generally normal pressure.The pressure of material in pressure chamber is to adjust the valve seat of homogenizing valve and the gap between the push rod is realized by pressure regulator, and the gap between valve seat and the push rod is more little, and pressure is more high.But the gap between valve seat and the push rod is more little, just more easy to be blocked, after in running order homogenizing valve is blocked, pressure in the homogenizer sharply raises, the safety value that surpasses homogenizer easily, cause danger, when perhaps thicker thing piece is stuck in the gap of valve seat and push rod, cause the gap to strengthen, cause pressure to descend, so homogenizer is had relatively high expectations to processed material, generally in 40um, but a spot of thicker block can be arranged all in the material, when especially insoluble fibre content is higher, material is very inhomogeneous, causes pressure instability easily.Homogenizer superelevation pressure (＞90MPa) when work, sealing gasket is broken easily, broken sealing gasket enters in the material, stops up homogenizing valve especially easily, causes the pressure of material in the pressure chamber sharply to raise, and causes danger.Because this voltage stabilizing homogenizer is equipped with filter in pressure chamber, material enters pressure chamber from plunger cavity by check valve, material filters by cancellated filter in pressure chamber, because filter filters out the thicker block in the material, under the effect of certain pressure intensity, material all can be smoothly by the gap of valve seat and push rod, can not stop up homogenizing valve, also can not be stuck in the gap of valve seat and push rod, so can finish smoothly the homogeneous micronization of material is handled, the pressure of material big fluctuation can not occur in the pressure chamber, thereby has realized the purpose of homogenizer automatic voltage regulation.

Advantage of the present utility model and effect are: the utility model has replaced the homogenizer of band over-pressure safety device in the past, the problem of the pressure instability when having solved homogenizer super-pressure.The problem of the pressure instability when the utility model has solved homogenizer super-pressure with simple form, the cost when having reduced the work of homogenizer super-pressure.The utility model is simple to operate, and cost is low.
