Abstract
What the present invention relates to is centrifugal apparatus for measuring distribution of particle size.In order to prevent that the test sample point from departing from the photometry axis, make the disk motor rotating of peculiar stopple coupon have an installation component.A light source and an optical receiver are arranged on this installation component, and both see through described disk toward each other.
Description
The present invention relates to a kind of apparatus for measuring distribution of particle size, specifically, relate to a kind of centrifugal apparatus for measuring distribution of particle size.
What Fig. 2 represented is the rough structure of the centrifugal apparatus for measuring distribution of particle size of routine.The disk made with aluminium etc. of 1 expression wherein, it is contained on the turning axle 3 of motor 2, is used for the stopple coupon S of holding height printing opacity.By the snubber assembly 4 that constitutes by spring etc. described motor 2 is contained on the mounting seat 5.6 expressions include the light source of tungsten-halogen lamp; 7 expressions include the optical receiver of several silicon photoelectric diodes; Described light source 6 and optical receiver 7 all are contained on the bracing frame 8.Bracing frame 8 stands on the mounting seat 5.Light source 6 and optical receiver 7 see through described disk 1 toward each other.
Above-mentionedly be the benefit that motor 2 is installed on the mounting seat 5 by snubber assembly 4: not only can avoid since described disk 1 grade in its rotary course center of gravity move the vibration that produces, and can avoid twisting force on described turning axle 3.
Although disk 1 and motor 2 such " rotary systems " are not to be fixedly mounted on the base 5, but by moving horizontally 4 holdings of ground snubber assembly, but light source 6 and optical receiver 7 such " optical systems " but are on the bracing frame 8 that is fixed on the mounting seat 5.Like this, in measuring process, stopple coupon S just might remove from the assigned address of photometry axis that light source 6 and optical receiver 7 are coupled together, thereby can not measure accurately.
That is to say, in the device of routine, because rotary system and optical system do not rely on each other mutually, so test sample point (installation site of stopple coupon 1) might depart from the photometry axis.
One object of the present invention is to provide a kind of apparatus for measuring distribution of particle size; In the process of measuring by rotating circular disk, this device can avoid the test sample point to depart from the photometry axis, thereby can measure accurately.
In the present invention, to achieve these goals, make the disk rotation of holding stopple coupon, the motor with snubber assembly is provided with an installation component, and light source and optical receiver are placed on the described installation component.
Like this, rotary system just with the optical system integrator so that relative position relation does not change, thereby can avoid the test sample point to depart from the photometry axis between the two, provide a kind of height reliable apparatus for measuring distribution of particle size.
What Fig. 1 represented is according to apparatus for measuring distribution of particle size of the present invention.
What Fig. 2 represented is conventional device.
With reference to Fig. 1, most preferred embodiment of the present invention is described below.In Fig. 1, identical with Fig. 2 or corresponding parts have been put on the label the same with Fig. 2, have omitted description of them simultaneously.
9 the expression be installation component, it is fixed on and makes on round alliance 1 motor rotating 2 of holding stopple coupon S; Installation component 9 is provided with a light source 6 and an optical receiver 7, and both see through described disk 1 toward each other.
As mentioned above, because optical system that light source 6 and optical receiver 7 are such and disk 1 and motor 2 such rotary systems are integrated, like this, although the direction of rotary system arrow indication in Fig. 1 moves in measurement, it almost is moving of equivalent that optical system is also done towards the direction identical with rotary system, thereby prevented the variation of position relation between 1 li test sample point of disk and the photometry axis, so that relative position relation does not change between the two, therefore avoided owing to the test sample point departs from the measuring error that the photometry axis produces.
Claims (1)
1, a kind of apparatus for measuring distribution of particle size, wherein, stopple coupon places on the disk, this disk rotates with the driving of the motor of snubber assembly, it is characterized in that: described motor has an installation component, a light source and an optical receiver are arranged on this installation component, and both by described disk toward each other.
