Abstract
The utility model discloses a powder lot dispersing pump, which belongs to the power lot work area and consists of a pump base, a skelp blower, a hopper and a porting ring, wherein, the skelp blower and the porting ring are coaxially arranged inside the pump base; a hopper outlet is communicated with a dispersing cavity between the skelp blower and the porting ring which are arranged inside the pump base. Compared with the prior art, the powder lot dispersing pump of the utility model has small cubage, good dispersing effect and can be widely applied to powder lot dispersing procedures during the process of silt test.
Description
Technical field
The utility model relates to field of powder engineering, and especially a kind of powder that dried powder is fully disperseed in air disperses pump.
Background technique
When utilizing laser particle analyzer that powders material is tested, must make it in liquid, fully to disperse (rewet test), perhaps in gas, fully disperse (dry method test).For all kinds of powder samples that chemistry, change in physical can take place in the aqueous solution (as cement etc.), must use the dry method test again, that is to say to make such sample in gas, be dispersed into individual particle.Though powder is easy to disperse in solution, want to allow it be well-dispersed among the air relatively difficulty.
Summary of the invention
Technical assignment of the present utility model is to provide a kind of powder to disperse pump at above-mentioned deficiency of the prior art, and this powder disperses pump to have characteristics such as volume is small and exquisite, dispersion effect is good.
The technological scheme that its technical problem that solves the utility model adopts is: powder disperses pump, constitute by pump seat, air nozzle, hopper and restricting orifice, air nozzle and restricting orifice are coaxial to be arranged in the pump seat, and hopper outlet is connected with dispersion chamber between pump seat inner nozzle and the restricting orifice.
Outer wall in the air nozzle suction tude is provided with adjusting nut, is used to regulate the distance between air nozzle and the restricting orifice.
The center-hole diameter of described air nozzle is 0.3-3mm, and spray nozzle front end outer conical drift angle is the 60-90 degree, and inner hole cone end drift angle is the 30-60 degree.
Described restricting orifice is cylindrical restricting orifice, its a fluid stream flows into face and effluent face is taper shape, the a fluid stream outflow side of restricting orifice is provided with discharge nozzle in pump seat, and the inner chamber of discharge nozzle becomes tapered configuration, and its inner chamber maximum diameter and its length ratio are 1: 5-1: 10.
The preferred 1-4mm of the center-hole diameter of restricting orifice.
Powder of the present utility model disperses pump to compare with prior art, has following outstanding beneficial effect:
(1) fluid mechanics principle according to Venturi tube designs, and the cluster of grains in turbulent flow is subjected to the multiple effect of wall attachment effect and current gradient and normal shock wave, is segregated into individual particle, and dispersion effect is good, can improve the test accuracy of laser particle analyzer greatly;
(2) nozzle location is adjustable, helps controlling as required dispersion effect.
(3) preparation process is simple, volume is small and exquisite, durable in use.
Description of drawings
Accompanying drawing 1 is that the utility model powder disperses the pump structure schematic representation.
Embodiment
With reference to Figure of description powder of the present utility model is disperseed to explain below the pump work.
Powder of the present utility model disperses pump to be made of pump seat 1, air nozzle 2, adjusting nut 3, hopper 4, restricting orifice 5 and discharge nozzle 6.Air nozzle 2, restricting orifice 5, discharge nozzle 6 is coaxial successively is fixed in the pump seat 1, forms between pump seat 1, air nozzle 2 and the restricting orifice 5 and disperses chamber 7, and the outlet that is fixed on the hopper 4 on the pump seat 1 is connected with dispersion chamber 7.Adjusting nut 3 is arranged on the outer wall of air nozzle 2 suction tude 8, by the distance between rotation adjusting nut 3 adjustment air nozzles 2 and the restricting orifice 5.
Wherein, air nozzle 2 center-hole diameters are 1mm, and spray nozzle front end outer conical drift angle is 80 degree, and inner hole cone end drift angle is 50 degree; Restricting orifice 5 is the cylindrical ceramic restricting orifice, and its a fluid stream flows into face and effluent face is taper shape, and center-hole diameter is 2.6mm; The inner chamber of discharge nozzle 6 becomes tapered configuration, and its inner chamber maximum diameter and its length ratio are 1: 8.
During use, the clean air of 1-8MPa enters the restricting orifice 5 that powder disperses pump through air nozzle 2, disperses chamber 7 because the suction function of high velocity air sucks the powder in the hopper 4.Powder is with after gas fully mixes, and Dual-Phrase Distribution of Gas olid forms turbulent flow and makes cluster of grains be sheared into individual particle under the normal shock wave effect, through discharge nozzle 6 outputs.Reconcile air nozzle 2 and can effectively increase the flow velocity of air-flow, thereby improve the absolute value of negative pressure, help particle and disperse with the relative distance of restricting orifice 5.Expansion-convergent chamber after the restricting orifice 5 then has certain effect to the derivation tool of the further dispersion of particle and stable Dual-Phrase Distribution of Gas olid.
Powder of the present utility model disperses its processing and fabricating of pump very simple and convenient, gets final product according to universal machine processing method processing and fabricating shown in the by specification accompanying drawing.
Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
