Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1 to 5, the sampling device of the centrifuge of the coal preparation plant of the present invention comprises a centrifuge 1 and a hollow tubular body 2. The side wall of the centrifuge 1 is provided with a sampling through hole (not shown in the figure) which can be opened by an end cover 3, and the hollow tubular body 2 is of a structure with one closed end. One closed end of the hollow tubular body 2 penetrates through the sampling through hole and is arranged in the centrifuge 1, and the other end of the hollow tubular body 2 extends to the outer side of the centrifuge 1 and is closed through the cover plate 4.
The left end and the right end of the hollow tubular body 2 are respectively provided with a sample inlet hole 5 and a sample outlet hole 6, and the sample inlet hole 5 and the sample outlet hole 6 are both positioned at the top of the hollow tubular body 2. Wherein, the sample inlet 5 is positioned at one end of the hollow tubular body 2 arranged in the centrifuge 1, and the sample outlet 6 is positioned at one end of the hollow tubular body 2 arranged outside the end cover 3. The sample inlet 5 is used for falling into the sampled clean coal, and the sample outlet 6 is used for sampling and observing.
A sampling rod 7 extending to the bottom of the hollow tubular body 2 is inserted into the center of the cover plate 4, the other end of the sampling rod 7 extends out of the hollow tubular body 2 and is connected with a push plate 8, and the sampling rod 7 is movably connected with the cover plate 4. The end of the sampling rod 7 located in the hollow tubular body 2 has a sampling cavity 9.
When the centrifuge 1 is in the centrifugal sampling process, part of the clean coal falls into the sampling hole 5 in the centrifuge 1 through rotation, wherein the sampling cavity 9 corresponds to the sampling hole 5 in position, so that part of the clean coal falls into the sampling cavity 9 on the sampling rod 7 through the sampling hole 5 on the hollow tubular body 2 through rotation, and the sampling cavity 9 is used for storing the sampled clean coal.
The side wall of the centrifuge 1 is provided with a fixing plate 10, the fixing plate 10 is provided with a sliding groove 11, and the push plate 8 is arranged in the sliding groove 11 in a matching way.
The fixed plate 10 is provided with a speed reducing motor 12, the output end of the speed reducing motor 12 is connected with a cam 14 through a rotating shaft 13, and the cam 14 is positioned at the right side of the push plate 8. One end of the sampling rod 7, which is positioned outside the hollow tubular body 2, is provided with a partial compression spring 15, one end of the compression spring 15 is connected to the push plate 8, and the other end of the compression spring 15 is fixed on the cover plate 4.
The gear motor 12 is started, and the gear motor 12 drives the cam 14 to rotate through the rotating shaft 13. When the convex part of the cam 14 rotates to the push plate 8, the push plate 8 is pushed to horizontally slide leftwards in the sliding chute 11, the compression spring 15 is compressed, the sampling cavity 9 on the sampling rod 7 is moved to the sampling hole 5 on the hollow tubular body 2, and part of the clean coal falls into the sampling cavity 9 on the sampling rod 7 from the sampling hole 5 on the hollow tubular body 2 through rotation. When the convex part of the cam 14 rotates to be away from the push plate 8 slowly, at the moment, under the buffer action of the compression spring 15, the push plate 8 slowly slides horizontally to the right in the sliding groove 11, so that the sampling cavity 9 on the sampling rod 7 is driven to move to the sampling hole 6 on the hollow tubular body 2, and the sampling observation process is completed once. The above steps are repeated, and sampling observation can be repeatedly carried out. The process effectively shortens the sampling time and improves the sampling work efficiency.
When in use, the cam 14 is driven by the speed reducing motor 12 to rotate, and under the combined action of the compression spring 15, the cam 14 drives the push plate 8 to horizontally move left and right in the sliding groove 11. When the push plate 8 moves leftwards, the compression spring 15 is compressed, the sampling cavity 9 on the sampling rod 7 is moved to the sampling hole 5 on the hollow tubular body 2, and part of the clean coal falls into the sampling cavity 9 on the sampling rod 7 from the sampling hole 5 on the hollow tubular body 2 through rotation; then under the buffer action of the compression spring 15, the push plate 8 is pushed rightwards, the sampling cavity 9 for storing part of the clean coal on the sampling rod 7 is driven to move to the sampling hole 6 on the hollow tubular body 2, and therefore sampling observation is completed.
This device can directly start gear motor 12 and can accomplish the sample, has replaced the tradition to take a sample through uncapping with the spade, shortens the sample time, effectively improves the work efficiency of sample, has thoroughly eliminated centrifuge 1 and has uncapped the potential safety hazard of sample. Meanwhile, leakage of coal materials and loss of clean coal are avoided, centrifugal sampling procedures are reduced, the working flow is simplified, and the labor intensity is reduced.
The above description is only for the preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
