Abstract
A high-efficiency bulk density instrument comprises a measuring cylinder. The instrument is characterized in that the measuring cylinder is mounted in a spring seat, a central shaft is fixed on the bottom of the spring seat, a bearing is mounted on the upper part of the central shaft and in a fixed bearing pedestal, a cam is arranged on the end of the central shaft, and is connected with a gear reducer motor, a spring is added on the lower part of the central shaft and positioned between the spring seat and the cam, and the spring seat and the gear reducer motor are mounted on a base. The camwhich is directly connected with the gear reducer motor drives the spring seat by means of the central shaft to move up and down, and when the cam rotates, the measuring cylinder containing sample isvibrated along with the spring seat to carry out a bulk density test. The utility model applies the principle of mechanical eccentric vibration to ensure that the catalyst sample loaded in the measuring cylinder can be vibrated at a constant speed and a high frequency, and a bulk density test can be fulfilled within about one minute. The utility model not only is highly efficient and accurate butalso reduces the labor intensity of engineering technicians.
Description
Technical field
The utility model relates to a kind of efficient heap specific density instrument.
Background technology
Heap specific density index is an industrial catalyst important process technical indicator, and the check of heap specific density is engineering technical personnel's random sampling at any time in catalyzer commercial production and the development process, all must carry out the process of repeatedly repetitive operation every day.This operation is contained in sample in the graduated cylinder exactly, and hand-held graduated cylinder makes the base of graduated cylinder be subjected to slight bump continuously, and the material that is contained in the graduated cylinder progressively obtains closely knit filling effect under the bump oscillating action.This result of check manually, its otherness is very big, because the length of the height of the size that everyone exerts oneself, frequency, time all is discrepant.And the deadline long (half an hour), labour intensity is bigger.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of efficient heap specific density instrument, and mechanically actuated improves checkability, reduces labor intensity.
A kind of efficient heap specific density instrument of the present utility model, comprise graduated cylinder, it is characterized in that described graduated cylinder is installed in the spring base, the fixedly connected central shaft in the bottom of spring base, central shaft top is equipped with bearing, and Bearing Installation is in bearing fixed seat, the central shaft end is provided with cam, cam is connected with the gear reduction motor, is added with spring in the bottom of central shaft between spring base and cam, and spring base, gear reduction motor are installed on the support.
Described graduated cylinder is installed in the spring base by swivel nut, is added with stop pin between swivel nut and the spring base.
Described gear reduction motor connects speed regulator.
The utility model is to move up and down by driving spring base with the direct-connected cam of gear reduction motor by central shaft, and the graduated cylinder of splendid attire sample vibrates with spring base when cam rotation, finishes the test of heap specific density.The track that spring base moves up and down is spacing by the holder that bearing is housed.
Advantage of the present utility model:
The principle of the utility model utilization mechanical eccentric vibration makes the catalyst samples dither at the uniform velocity in the graduated cylinder of packing into, finishes the experiment of a heap specific density in the time about 1 minute.Not only efficient is high but also accurate, has alleviated engineering technical personnel's labour intensity.
