Abstract
The utility model relates to an improved air borne powder meter, which is suitable for measuring the dusting performance of powdery or granular substance with the constant-pressure quantitative air jetting method. The main technical characteristic of the air borne powder meter is that the operation process is controlled by the mechanical electric apparatus linkage device. The air borne powder meter has the advantages of good test reiterative performance and high accuracy. The air borne powder meter overcomes the defect that the dusting tester of the existing Sandoz has poor test reiterative performance caused by the manually operated test process.
Description
The utility model is the instrument that a kind of improved mensuration material plays the dirt performance, is applicable to the quantitative air gunite of constant voltage the dirt performance that rises of powdery or particulate matter is measured.
The current mensuration that powdery or particulate matter are played the dirt performance has several different methods, as photoelectric tube method (Hoeshct company), thin light scattering method (ICI company), splashing property determination method (Japan) and the quantitative air gunite of constant voltage (Sandoz company).Wherein to have equipment simple for the quantitative air gunite of constant voltage, operates advantages such as simple and easy.
The dirt performance that the quantitative air gunite of constant voltage is measured powdery or shot-like particle is to play dirt with powdery or shot-like particle through the injection of the quantitative air of constant voltage, and the dirt situation that rises of collecting after 30 seconds in 60 seconds is graded.The dirt test instrument that rises of Sandoz company is to make testing tube with graduated cylinder, and the filter paper fixator is a metal wire frame, also has the shower nozzle of supplying gas, gas-holder, conduit, spring clamp of four arm nozzle-types etc. in addition.During test, sample places the testing tube bottom, open spring clamp, the quantitative air of constant voltage is sprayed onto on the sample from the shower nozzle of supplying gas through conduit, the shower nozzle of will supplying gas in 30 second time subsequently vertically takes out from the testing tube upper end open, and will be equipped with the filter paper fixator that detects filter paper and vertically put into from the testing tube upper end open, stops after 60 seconds and take out, at last detection filter paper is graded.Test operation generally need have two operators to cooperate to carry out, and whether test result accurately has bigger relation with the operator to the grasp of running time.In addition, make testing tube because of adopting graduated cylinder, be equipped with when the filter paper fixator that detects filter paper is put into and be difficult for steadily, what also influence detected normally carries out.For above-mentioned reasons, when using the playing the dirt test instrument and measure powdery or shot-like particle and play the dirt performance of Sandoz company, operator's individual skill and mated condition are bigger to the test result influence, and the test repeatability is relatively poor, influences precision of test result.
In order to overcome the shortcoming that the dirt test instrument exists that rises of Sandoz company, the utility model is taked with machinery---and the control system of electrical equipment interlock is come the means of control operation process, the running time is accurate when having reached test, eliminated of the influence of operator's individual skill, improved the repeatability and the accuracy of test test result.
Task of the present utility model is finished as follows:
In order to reach with machinery, electrical equipment control operation, the testing tube of analyzer described in the utility model has a notch in a side; The filter paper fixator is the combination of garden ring and garden annular groove plate, will detect filter holder during test between the two.The filter paper fixator can stretch in the pipe along the notch of testing tube and detect.The motion of shower nozzle and filter paper fixator of supplying gas in the analyzer is subjected to the control of the time relay and trapezoidal screw, and is accurate to reach the running time, is not subjected to the purpose of the influence of operator's individual skill.
The control that the above-mentioned time relay, trapezoidal screw move in test process to supply gas shower nozzle and filter paper fixator can by they and solenoid valve, motor, reductor, cable wire, extension spring etc. machinery---electrical equipment makes up and reaches.Motor wherein, reductor, the trapezoidal screw combination drives the shower nozzle of supplying gas and does in testing tube, following motion, and the control shower nozzle of supplying gas was raised to the testing tube upper port in 30 seconds behind ejection constant voltage quantitative air, the filter paper fixator then is connected with trapezoidal screw by cable wire, when trapezoidal screw rises, cable wire with the filter paper fixator along the notch of testing tube in the jet back test position that entered in the testing tube in 30 seconds, stop after 60 seconds, motor is done counter motion according to the control of the time relay, trapezoidal screw is moved down, cable wire unclamps, and the filter paper fixator relies on the effect of extension spring to withdraw from testing tube.During test, solenoid valve, the time relay, motor are to start running synchronously.Owing to adopted means mechanical, the electrical equipment control operating process, not only improved the accuracy of test, test operation also only needs an operator to finish simultaneously.
Dust from flying analyzer wiring layout described in the utility model as shown in Figure 1, its critical piece is as follows: testing tube (3), filter paper fixator (4), the shower nozzle of supplying gas (2), conduit (5), the time relay (12), solenoid valve (11), gas-holder (10), motor (8), reductor (7), trapezoidal screw (6), cable wire (1), extension spring (9).Supply gas shower nozzle (2) as shown in Figure 2.The garden that is combined into filter paper fixator (4) is encircled as shown in Figure 3.Garden annular groove plate as shown in Figure 4.
Testing tube in the analyzer described in the utility model is the straight shape garden tube that a side has notch.This straight shape garden tube also can be taked to be combined by several segmentations in the vertical.The device of this combination not only helps processing, the maintenance of equipment, and the while also brings convenience cleaning, the mounting or dismounting of testing tube behind each sample determination.
Testing tube useable glass in the analyzer described in the utility model, organic glass, plastic or other material are made.It is convenient that wherein glass has cleaning, is difficult for advantages such as staining, but carry out relatively difficulty of notch processing.Though organic glass, plastics staining easily, non-friable, the processing of notch is also more convenient.Therefore also can adopt the method for making of different materials for knockdown testing tube at different parts.
In order to help the processing and manufacturing of equipment, the nozzle component of supplying gas in the analyzer described in the utility model can adopt broadening formation, has aperture in the hydraucone bottom, and constant pressure air can spray through aperture.
For the above-mentioned broadening formation shower nozzle of supplying gas, the little hole count of hydraucone bottom with 4 Kongzuis for suitable.The air-flow of its ejection is even, and the test result stepping is clear.
Example
Testing tube combines by 4 sections: seat body, trough of belt mouth seat body, seat body, base.Wherein: two seat bodies all are that glass is made, trough of belt mouth seat body and base plastic production.The shower nozzle of supplying gas is a broadening formation, and the hydraucone bottom has 4 apertures.
