Description

Technical Field

[0001] This utility model relates to the field of measurement technology for mining machinery and equipment, and in particular to a tool for quickly detecting the diameter of the sediment discharge port of a hydrocyclone. Background Technology

[0002] In mineral processing, hydrocyclones are commonly used classifying devices. They rely on the internal rotation of the slurry to classify particles based on differences in centrifugal force. Coarse particles are discharged through the underflow nozzle, while fine particles are discharged through the overflow pipe. Because the underflow particles are relatively coarse, the underflow nozzle is highly susceptible to wear, and an increase in its diameter can severely affect the classification accuracy and efficiency of the hydrocyclone. Therefore, regularly measuring the underflow nozzle and replacing it promptly when wear exceeds the specified range is crucial for ensuring normal production.

[0003] Existing measurement methods have many drawbacks:

[0004] Manual touch judgment method: It relies entirely on the operator's experience, is highly subjective, has a large measurement error, and cannot obtain accurate measurement data.

[0005] Simplified disc measurement method: This method involves inserting a set of standard-sized discs into the sand discharge opening to determine the diameter of the opening, with the largest disc size that allows it to pass through being used to determine the diameter of the discharge opening. This method has low accuracy and requires multiple sets of discs of different sizes, making it inconvenient to operate.

[0006] The disassembly and measurement method for underrunner nozzles, while highly accurate, is time-consuming, labor-intensive, and inefficient. In continuous mining operations, frequent disassembly of equipment can disrupt production and cause unnecessary economic losses.

[0007] Based on the above situation, there is an urgent need for a special tool that can overcome the shortcomings of existing technology and achieve rapid, accurate and convenient measurement of the diameter of the hydrocyclone's sand discharge port. Utility Model Content

[0008] The purpose of this invention is to provide a tool for quickly detecting the diameter of the hydrocyclone's underflow discharge port, in order to solve the problems of difficulty, low efficiency, and large error in measuring the diameter of the hydrocyclone's underflow discharge port in the existing technology, and to make the hydrocyclone underflow discharge port diameter detection tool simple in structure, convenient in operation, accurate in measurement, and highly efficient.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] The purpose of this utility model is to provide a tool for quickly detecting the diameter of the underflow discharge port of a hydrocyclone, in order to solve the problems of difficulty, low efficiency and large error in measuring the diameter of the underflow discharge port of a hydrocyclone in the existing technology. This utility model aims to provide a hydrocyclone underflow discharge port diameter detection tool that is simple in structure, convenient to operate, accurate in measurement and highly efficient.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1

[0035] This embodiment provides a tool for quickly detecting the diameter of the underflow discharge port of a hydrocyclone, such as... Figures 1-7 As shown, the tool includes: an inner rod 2, an outer sleeve rod 4, a hand handle 1, a radial expansion measuring mechanism, and a locking mechanism. The inner rod 2 has a first end and a second end that are arranged opposite to each other, and a scale line 201 is provided on the inner rod 2. The outer sleeve rod 4 is coaxially sleeved on the outside of the inner rod 2 and can slide relative to each other axially and maintain its position after sliding. The hand handle 1 is fixedly connected to the first end of the inner rod 2 away from the outer sleeve rod 4. This structural design makes the layout of each component of the tool reasonable. The coaxial sliding setting of the inner rod 2 and the outer sleeve rod 4 provides a basis for subsequent radial expansion measurement. The fixed connection of the hand handle 1 makes it convenient for the operator to hold and apply force, which facilitates the operation of the tool for measurement work. The scale line 201 provides an intuitive way to read the measurement results. The radial expansion measuring mechanism includes a first support sleeve 6, a second support sleeve 9, multiple arc-shaped contact pieces 5, multiple first connecting rods 7, and multiple second connecting rods 7. The first support sleeve 6 is detachably fixedly connected to the end of the outer sleeve rod 4 away from the handle 1. The first end of the inner rod 2 passes through the outer sleeve rod 4 and is detachably fixedly connected to the second support sleeve 9. One end of the first connecting rod 7 is hinged to the first support sleeve 6, and the other end is hinged to the inner side of the arc-shaped contact piece 5. One end of the second connecting rod 7 is hinged to the second support sleeve 9, and the other end is hinged to the inner side of the arc-shaped contact piece 5. The outer sleeve rod 4 slides relative to the inner rod 2, causing the first support sleeve 6 and the second support sleeve 9 to move closer or further apart, thereby causing the arc-shaped contact pieces 5 to synchronously expand or contract radially. A locking mechanism is located at the end of the outer sleeve rod 4 near the handle 1 to lock the position of the outer sleeve rod 4 after it slides relative to the inner rod 2. Through the connection relationship and movement mode of each component, the radial expansion measuring mechanism can accurately achieve synchronous radial expansion or contraction of the arc-shaped contact pieces 5, ensuring contact with the inner wall of the hydrocyclone's sediment discharge port and adapting to discharge ports of different diameters. The detachable fixed connection facilitates maintenance and replacement of components. The locking mechanism ensures the stability of the relative position of the outer sleeve rod 4 and the inner rod 2 during measurement, thus ensuring the accuracy of the measurement results.

[0036] In a preferred embodiment, the radial expansion measuring mechanism further includes a first locking nut 8 and a second locking nut 10. The outer sleeve rod 4 has a first mounting section at its end away from the handle 1, and a first threaded section at its end away from the handle 1. A first support sleeve 6 is fitted onto the first mounting section, and the first locking nut 8 is threadedly connected to the first threaded section to lock the first support sleeve 6 firmly against the first mounting section. The inner rod 2 has a second mounting section at its end away from the handle 1, and a second threaded section at its end away from the handle 1. A second support sleeve 9 is fitted onto the second mounting section, and the second locking nut 10 is threadedly connected to the second threaded section to lock the second support sleeve 9 firmly against the second mounting section. The arrangement of the first locking nut 8 and the second locking nut 10 further enhances the stability of the connection between the first support sleeve 6 and the second support sleeve 9. When the tool is used for a long time or subjected to external forces, this threaded connection and locking method effectively prevents the support sleeve from loosening or shifting, ensuring the normal operation and measurement accuracy of the radial expansion measuring mechanism.

[0037] In a preferred embodiment, the locking mechanism includes a locking screw 3. A threaded hole 401 is provided at one end of the outer sleeve rod 4 near the handle 1. The locking screw 3 is threaded into the threaded hole 401, and one end of the locking screw 3 extends into the outer sleeve rod 4 and presses against the inner rod 2 to maintain the relative position of the inner rod 2 and the outer sleeve rod 4. This simple locking screw 3 structure, through threaded connection and pressing against the inner rod 2, can conveniently and quickly lock the relative position of the outer sleeve rod 4 and the inner rod 2. When the measurement position needs to be adjusted, the locking screw 3 can be loosened; when the position is determined for measurement, the locking screw 3 can be tightened to fix it. The operation is simple and efficient, ensuring the stability of the tool structure during measurement.

[0038] In a preferred embodiment, the locking screw 3 includes a lead screw 301, a rotating handle, and a locking block 302. The rotating handle is fixedly connected to one end of the lead screw 301. The diameter of the locking block 302 is larger than the diameter of the lead screw 301, and the locking block 302 is fixedly connected to the other end of the lead screw 301. The lead screw 301 is used for threaded connection with a threaded hole 401. An enlarged hole is provided on the inner side of the threaded hole 401. The locking block 302 is located at the enlarged hole and can extend out of the enlarged hole and abut against the inner rod 2 under the action of the lead screw 301. The rotating handle facilitates the operator to rotate the lead screw 301, increasing the convenience of operation. The locking block 302 has a larger diameter than the lead screw 301 and can abut against the inner rod 2 under the action of the lead screw 301. This design makes the abutment more stable and firm, effectively preventing relative displacement between the inner rod 2 and the outer sleeve rod 4 during measurement, ensuring the reliability of the measurement results. The enlarged hole inside the threaded hole 401 provides suitable movement space for the locking stop 302, enhancing the rationality of the overall structure.

[0039] In a preferred embodiment, the system further includes multiple hinge seats 11, through which the first connecting rod 7 and the second connecting rod 7 are hinged to the arc-shaped contact piece 5. The hinge seats 11 make the hinge between the first and second connecting rods 7 and the arc-shaped contact piece 5 more flexible and smooth. During the radial expansion or contraction of the arc-shaped contact piece 5, it can better adapt to changes in the angle between the components, ensuring the continuity and stability of the movement, thereby improving the accuracy of the measurement operation.

[0040] In a preferred embodiment, the curvature of the outer surface of the arc-shaped contact piece 5 is adapted to the standard inner wall curvature of the hydrocyclone's underflow discharge port. This adaptation of the outer surface curvature of the arc-shaped contact piece 5 to the standard inner wall curvature allows for a better fit when it contacts the inner wall of the discharge port. This enables more accurate measurement of the inner diameter of the hydrocyclone's underflow discharge port, improving measurement precision and reducing measurement errors caused by poor contact.

[0041] In a preferred embodiment, the number of arc-shaped contact pieces 5 is six, and they are evenly arranged along the circumferential direction of the inner rod 2. The six evenly arranged arc-shaped contact pieces 5 can acquire data from multiple angles when in contact with the inner wall of the hydrocyclone's sediment discharge port, comprehensively and accurately reflecting the inner diameter of the discharge port. Compared to a smaller number, the measurement results are more representative and accurate, and the evenly distributed layout also helps ensure the overall balance of force on the tool during measurement.

[0042] In a preferred embodiment, the minimum scale value of the scale line 201 is 0.1 cm, and the starting zero point of the scale line 201 corresponds to the outer contour edge of the arc-shaped contact piece 5 when it is in the contracted state. The relatively small minimum scale value of 0.1 cm can meet the requirements of high-precision measurement. The fact that the starting zero point of the scale line 201 corresponds to the outer contour edge of the arc-shaped contact piece 5 in the contracted state allows the operator to directly read the scale value to obtain the inner diameter of the discharge port after the measurement is completed, without the need for additional measurement or conversion, making the measurement process more intuitive and convenient.

[0043] In a preferred embodiment, both the inner rod 2 and the outer sleeve rod 4 are made of high-strength aluminum alloy, which is lightweight and has high strength. Using this material to manufacture the inner rod 2 and the outer sleeve rod 4 reduces the overall weight of the tool, making it easier for operators to hold and operate for extended periods, thus reducing labor intensity. Furthermore, the high strength meets the structural strength requirements of the tool during use, ensuring that the tool can withstand certain external forces without deformation, thereby ensuring the accuracy and reliability of the measurement.

[0044] Example 2

[0045] This utility model also provides a method for using a tool for quickly detecting the diameter of the underflow discharge port of a hydrocyclone as described in any of the above claims, including the following steps:

[0046] S1: Align the radial expansion measuring mechanism with the hydrocyclone's sand discharge port, ensuring that the arc-shaped contact piece 5 is in a contracted state. Hold the handle 1 and slowly insert the measuring mechanism into the discharge port until the arc-shaped contact piece 5 reaches the position to be measured.

[0047] S2: By pulling the outer sleeve rod 4, it slides axially relative to the inner rod 2. During this process, the first support sleeve 6 and the second support sleeve 9 move closer to each other under the drive of the first connecting rod 7 and the second connecting rod 7, thereby causing multiple arc-shaped contact pieces 5 to expand radially in sync until the outer surfaces of all arc-shaped contact pieces 5 are tightly fitted to the inner wall of the discharge port.

[0048] S3: Control the locking mechanism to keep the outer sleeve rod 4 and the inner rod 2 in their current relative positions to prevent slippage during measurement from affecting data accuracy;

[0049] S4: Observe the scale line 201 on the inner rod 2 and read the scale value corresponding to the end of the outer sleeve rod 4. This scale value is the diameter measurement value of the hydrocyclone's sand discharge port.

[0050] S5: After the measurement is completed, loosen the locking mechanism, slide the outer sleeve rod 4 in the opposite direction to retract the arc-shaped contact piece 5, and then remove the tool from the discharge port to complete the entire testing operation.

The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
