CONCRETE IMPLEMENTING METHOD

[0016] In order to make the purpose of the utility model, technical scheme and advantage more clearly clear, the following is combined with the drawing and example, and the utility model is further explained in detail.

[0017] Example 1

[0018] As Figure 1 Shown, centrifuge material level appearance, and this material level appearance has carried out a series of improvement on the original structure. The working principle of the original centrifuge ordinary material level appearance is based on mechanical type material level sensing principle. Specifically, the ordinary material level appearance includes a material level sensor, and the sensor includes a rotating shaft, a blade and a mechanical switch signal generator;When the material in the centrifuge rotates and thickens, the material will push the blade, and the blade will drive the rotating shaft to rotate;When the blade rotates to the predetermined angle, the switch signal generator will generate a switch signal;This signal is transmitted to the feeding device of the centrifuge through the control device, so as to control the stop of the feeding device.

[0019] In this way, the pain point of centrifuge ordinary material level appearance in use: when the material level appearance monitors the thickness of the material in the centrifuge, the drum rotates at high speed, and the material and slurry will impact and rub the lower detection blade of the material level appearance at high frequency, which will cause the blade to wear, and the frequent on-off of the mechanical switch will cause the switch to fail.

[0020] To this end, the improved material level instrument in structure includes a material level instrument mounting seat 1, one end of the material level instrument mounting seat 1 is rotatably adjusted and connected with a mounting sleeve 2 through a rotary adjusting structure, and the mounting sleeve 2 is centrally arranged; a cylinder 3 is arranged in the mounting sleeve, the cylinder body of the cylinder 3 is fixed on the rotary adjusting structure through bolts, the output end rod body of the cylinder 3 is movably telescopic through a limiting protection sealing cover 21, and the end head is rotatably connected with a rotating shaft 4 through a bearing, the other end of the rotating shaft 4 is detachably connected with a connecting shaft 5, and the connecting shaft 5 is connected with a rotating blade 6; and the limiting protection sealing cover 21 is detachably connected with the mounting sleeve 2 in a threaded manner.

[0021] In the implementation process of the improved material level instrument, the material level instrument is placed in a designated position, and then when the material thickness needs to be measured, the rotating blade 6 is conveniently extended into the material container to be measured by controlling the rotary adjusting structure to rotate to a suitable angle; then the rotating blade 6 connected with the rotating shaft 4 through the connecting shaft 5 is extended into the material container to be measured (a centrifuge) by controlling the cylinder 3 to elongate, and the material will drive the rotating blade 6 extended into the centrifuge to rotate; as the material in the centrifuge rotates and thickens, the rotating blade 6 extended into the centrifuge will also change, the rotating blade 6 drives the rotating shaft 4 to rotate and change; when the rotating blade 6 rotates to a predetermined angle, the top end of the rotating shaft 4 installed on the arranged sensor feeds back to the switch signal generator (prior art), and the switch signal generator generates a switch signal, which is transmitted to the feeding device of the centrifuge through the control device, so that the feeding device stops feeding into the centrifuge. In this embodiment, by increasing a rotatably arranged cylinder, the cylinder is rotated to the working area when detection is needed and is rotated to the non-working area when detection is not needed, so as to avoid impact and wear during non-detection time and increase the service life of the material level instrument.
