Abstract
The utility model relates to a novel standard test sieve shaker, which mainly comprises a sieve tray bracket arranged aslant, a frame and a high frequency oscillation motor; wherein a plurality of sieve trays for holding test sieves are arranged on the sieve tray bracket, a plurality of test sieves are arranged on the sieve trays in echelonment, while the sieve tray bracket is directly connected with the high frequency oscillation motor. The oscillation frequency can be adjusted continuously by an AC frequency converter. The entire bracket is arranged on the mobile frame through a damping spring. An accessional dry sieve clamp can also be arranged on the slant bracket to perform dry screening. The screening surface of the sieve shaker is open, so that washing water can be uniformly distributed on each sieve during sieve wetting, thus separation precision of sieving is enhanced. The device is capable of separating analyte once into 2 to 7 granularity levels, which saves time and labor, moreover is simple in configuration and durable with less maintenance parts.
Description
Affiliated technical field
The utility model relates to a kind of sieve shaker, is specifically related to a kind of wet type dither sieve shaker that ladder is arranged that is.
Background technology
The laboratory wet screening is to adopt various common dry type sieve shaker to be equipped with the special screen bottom tray that holds to carry out at present, or the artificial hand sieve, as using hand-held electromagnetic vibrator.Common dry type mechanical vibration sieve shaker vibration frequency is low, generally is not suitable for wet screening.Can carry out wet screening though be aided with the special electromagnetic type high-frequency vibration formula sieve shaker that holds screen bottom tray, but because each sieve is overlapped arrangement, each compass screen surface seals, and the flushing current can not be controlled in the distribution of compass screen surface, current are difficult for evenly distributing at each compass screen surface, and screening has bigger error; And most sieving machine itself also are unworthy of this special screen bottom tray that holds.Though hand sieving can reach degree of precision, labour intensity is big, and screening speed is low, and work efficiency is low.
Summary of the invention
The purpose of this utility model provides a kind of novel standard test sieve sieve shaker, and it is time saving and energy saving to have, simple in structure, and apparatus of repair parts is few, long-lived characteristics.
The purpose of this utility model is achieved through the following technical solutions.
The utility model mainly is made up of screen tray support, fuselage and a dither motor that tilts to install.A plurality of test sieves are installed on the screen tray support hold the sieve screen tray, test sieve promptly is installed in these and holds on the screen tray, stepped unlimited layout.The screen tray support then directly is connected with dither motor.Vibration frequency can be passed through any stepless adjustment of AC converter.Entire bracket is installed in one movably on the fuselage by shock-absorbing spring, and the walking castor is housed on the fuselage.In addition, the screen tray support also can be installed the dry screen anchor clamps, realizes the dry type screening.
The beneficial effects of the utility model are:
1, the dither mode that adopts ladder to arrange, compass screen surface is an open type, wash-down water can be uniformly distributed in each compass screen surface, to improve the screening separation accuracy.
2, this equipment can once be divided into the analysans material screen 2-7 different grain size rank, and is time saving and energy saving.
3, simple in structure, apparatus of repair parts is few, and is durable in use.
4, as additional dry screen anchor clamps, same equipment also can be used for the dry type screening.
Description of drawings
Fig. 1 is a basic structure synoptic diagram of the present utility model.
Among the figure: 1. screen tray support, 2. hold the sieve screen tray, 3. support spring, 4. frame, 5. walking castor, 6. dry screen anchor clamps, 7. dither motor.
Embodiment
As shown in Figure 1, this device is made up of screen tray support, fuselage and a dither motor that tilts to install, and a plurality of test sieves is installed on the screen tray support holds the sieve screen tray, and test sieve is installed in these and holds on the screen tray, stepped unlimited layout.The screen tray support then directly is connected with dither motor.Vibration frequency can be passed through any stepless adjustment of AC converter.Entire bracket is installed in one movably on the fuselage by shock-absorbing spring, and the walking castor is housed on the fuselage., each test sieve is placed in by fastener and respectively holds on the sieve screen tray 2, and material to be analyzed feeds from the promptly scalping of first sieve topmost, and screen underflow from flowing on the next stage sieve screen cloth, further sieves under flow action.Carry out according to this, enter bottom the just dusting cover screening of sieve until material.Each sieve compass screen surface opens wide, and is convenient to wash current the screening material is washed.Whole screening process can once sieve out 7 granularity ranks.
Behind affix dry screen anchor clamps 6, also can carry out the dry type screening.
Claims (4)
1, novel standard test sieve sieve shaker, mainly form by screen tray support, fuselage and dither motor, it is characterized in that: on the screen tray support, be equipped with and hold the sieve screen tray, test sieve is installed in and holds on the sieve screen tray, the screen tray support is connected with dither motor, and the screen tray support is installed on the fuselage by shock-absorbing spring.
