Abstract
Description
Technical Field
[0001] This application relates to the field of three-phase centrifuge maintenance and measurement technology, and in particular to a device for measuring the height of the spiral blades of a three-phase centrifuge. Background Technology
[0002] Three-phase centrifuges are core separation equipment in food waste treatment plants, achieving efficient separation of solid, liquid, and oil phases of materials through centrifugal force. Their operational stability directly affects the efficiency and quality of food waste treatment. During long-term operation, the spiral blades are prone to wear due to material friction. Therefore, during disassembly and overhaul, accurate measurement of the spiral blade height is a crucial step in determining the degree of blade wear, assessing the safety of equipment operation, and ensuring the subsequent stable operation of the equipment.
[0003] Currently, in the process of measuring blade height during the disassembly and overhaul of three-phase centrifuges, the industry lacks dedicated measuring tools, and depth gauges or vernier calipers are commonly used as general measuring instruments. However, this measurement method has significant technical drawbacks: First, because the assembly structure of the helical blades and steel cylinder lacks clear measurement reference markings, operators must rely on subjective experience to determine the measurement reference points. Differences in the selection of reference points lead to poor consistency in measurement results and are easily affected by human factors. Second, to compensate for the lack of accuracy caused by the ambiguity of the reference points, multiple repeated measurements are required to verify accuracy, which not only consumes a lot of manpower but also prolongs the equipment overhaul cycle. Third, the measurement principle of depth gauges and vernier calipers determines that they can only achieve single-point intermittent sampling measurements and cannot continuously detect the height of any position on the helical blade, making it difficult to comprehensively and accurately reflect the overall wear distribution of the blades.
[0004] The shortcomings of existing measurement technologies result in low accuracy, poor efficiency, and incomplete data in the measurement of the height of three-phase centrifuge spiral blades. These deficiencies fail to meet the practical needs for accuracy, convenience, and comprehensiveness during equipment overhauls, potentially affecting the reliability of blade wear assessment and posing safety hazards during equipment operation. Therefore, this invention proposes a device for measuring the height of three-phase centrifuge spiral blades. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0033] This application provides an embodiment of a three-phase centrifuge spiral blade height measuring device. Please refer to the following for details. Figures 1 to 3 .
[0034] The three-phase centrifuge spiral blade height measuring device in this embodiment includes: a measuring trolley for moving and measuring on the centrifuge cylinder 5; the measuring trolley includes a support base 1 and a magnetic roller 3 rotatably mounted on the support base 1; the magnetic roller 3 is used to magnetically attract the centrifuge cylinder 5 to the outer periphery, and to enable the support base 1 to move along the outer periphery of the centrifuge cylinder 5; a scale 2 is provided on the support base 1, and the extension direction of the scale 2 is configured to point to the center of the centrifuge cylinder 5 when the magnetic roller 3 is attracted to the centrifuge cylinder 5; a measuring end 4 is slidably provided on the scale 2 for overlapping the top of the centrifuge spiral blade during measurement.
[0035] It should be noted that this three-phase centrifuge spiral blade height measuring device forms a stable measurement benchmark by magnetically adsorbing the spiral blade height onto the centrifuge cylinder 5 using a magnetic roller 3. This avoids interference from human experience in judging the benchmark point, thereby effectively improving measurement consistency and accuracy. Furthermore, it can move along the outer circumference of the centrifuge cylinder 5, and the measuring end 4 can slide on the scale 2, enabling continuous detection of the centrifuge spiral blade height, thus comprehensively reflecting the overall wear distribution. It eliminates the need for repeated measurements and comparisons, saving labor costs, shortening equipment overhaul cycles, meeting the overhaul requirements for measurement accuracy, convenience, and comprehensiveness, and ensuring safe equipment operation.
[0036] The above is Embodiment 1 of a three-phase centrifuge spiral blade height measuring device provided in this application. The following is Embodiment 2 of a three-phase centrifuge spiral blade height measuring device provided in this application. Please refer to the following for details. Figures 1 to 3 .
[0037] The three-phase centrifuge spiral blade height measuring device in this embodiment includes: a measuring trolley for moving and measuring on the centrifuge cylinder 5; the measuring trolley includes a support base 1 and a magnetic roller 3 rotatably mounted on the support base 1; the magnetic roller 3 is used to magnetically attract the centrifuge cylinder 5 to the outer periphery, and to enable the support base 1 to move along the outer periphery of the centrifuge cylinder 5; a scale 2 is provided on the support base 1, and the extension direction of the scale 2 is configured to point to the center of the centrifuge cylinder 5 when the magnetic roller 3 is attracted to the centrifuge cylinder 5; a measuring end 4 is slidably provided on the scale 2 for overlapping the top of the centrifuge spiral blade during measurement.
[0038] It should be noted that the three-phase centrifuge spiral blade height measuring device is attached to the centrifuge cylinder 5 in the form of a trolley, which ensures that the extension line of the scale 2 always passes through the center of the centrifuge cylinder 5. This avoids the situation where the reference point deviation occurs due to the use of an oil dipstick, resulting in inaccurate measurement data, and achieves accurate measurement of the centrifuge spiral blade height.
[0039] Preferably, there is a gap between the support base 1 and the centrifuge cylinder 5, which makes it easier to move the measuring trolley. It is understood that there may also be no gap between the support base 1 and the centrifuge cylinder 5, that is, when the measuring trolley is magnetically attached to the centrifuge cylinder 5, the lower surface of the support base 1 is in contact with the outer surface of the centrifuge cylinder 5.
[0040] When the measuring end 4 is attached to the top of the centrifuge spiral blade, the scale mark indicated by the scale 2 is the vertical distance from the measuring end 4 to the outer surface of the centrifuge steel cylinder 5; wherein, the initial scale value of the scale 2 is equal to the vertical distance from the initial scale position to the outer surface of the centrifuge steel cylinder 5.
[0041] Understandably, by "pre-calibrating" the scale markings on ruler 2, the error caused by the physical gap is compensated, thus enabling direct reading.
[0042] The magnetic rollers 3 are symmetrically mounted on the front and rear sides of the support base 1, and the scale 2 is vertically fixed in the middle of the support base 1.
[0043] Specifically, there can be two magnetic rollers 3. The two magnetic rollers 3 are symmetrically rotated and installed on the front and rear sides of the support base 1, and the two magnetic rollers 3 have the same diameter.
[0044] Preferably, the magnetic roller 3 is detachably connected to the support base 1. When in use, the corresponding size of the magnetic roller 3 can be selected according to the diameter data of the centrifuge steel cylinder 5 to match the scale of the ruler 2.
[0045] Understandably, the scale 2 can also be mounted vertically on the support base 1. At this time, the zero point of the scale 2 is flush with the lower surface of the scale 2. When the measuring trolley is moved, the scale 2 can be lifted. When measurement is required, the scale 2 can be pressed onto the outer surface of the centrifuge steel cylinder 5.
[0046] Preferably, a tension spring can be provided between the measuring end 4 and the support base 1, so that the flat contact surface of the measuring end 4 always tends to press against the tip of the spiral blade, thereby making the operation more convenient.
[0047] Specifically, the measuring end 4 can be a pressure plate that is slidably connected to the scale 2.
[0048] Preferably, the support base 1 may be provided with a gripping part.
[0049] In practice, the magnetic roller 3 of the measuring trolley is first attached to the outer wall of the centrifuge cylinder 5. Then, the measuring end 4 is attached to the top of the spiral blade to be measured. Next, one hand holds the measuring trolley and drags it around the centrifuge cylinder 5, while the other hand presses the measuring end 4 so that it is close to the top of the spiral blade. By continuously reading the data on the scale 2, the height of the spiral blade can be continuously measured.
[0050] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
