Description

Technical Field

[0001] This utility model belongs to the field of quartz sand testing technology, specifically relating to a sample oscillator for quartz sand turbidity testing. Background Technology

[0002] The detection of turbidity in quartz sand is an important indicator for measuring the content of suspended particles in quartz sand suspension, and is often used in quartz sand processing, water treatment filter media performance evaluation and other scenarios.

[0003] The related technology (Chinese patent with publication number CN218885910U) includes a housing and a detector. The lower end face of the housing has two fixedly connected placement shells on its left and right sides. Springs are fixedly connected to the inner walls of each placement shell, and pressure plates are fixedly connected to the other ends of the springs. Sample bottles are placed inside each placement shell. A lid is slidably connected to the opening of each placement shell, and a pull ring is fixedly connected to the outer end face of each lid. Spring pins are fixedly connected to the grooves on the left and right sides of the inner wall of the housing, and pull rods are fixedly connected to the lower end faces of the spring pins. Through the placement shells, springs, pressure plates, spring pins, and pull rings, the sample bottles can be stored through the placement shells, enabling the turbidity detector to carry multiple sample bottles and quickly retrieve them. This solves the problem of not being able to easily carry multiple sample bottles when traveling, improving the convenience of the device.

[0004] In the turbidity testing of quartz sand, the sampling of the shaken suspension must strictly avoid the contamination of coarse particles settling at the bottom of the container, ensuring that the sample is taken from the middle of the suspension to guarantee representativeness. The currently used manual sampling method is difficult to control precisely, and is prone to bottom sampling or sampling at too high a position, which significantly limits the representativeness of the sample and thus affects the accuracy and reliability of the test results.

[0015] The sample shaker for testing the turbidity of quartz sand according to this utility model has the following advantages compared with the prior art:

[0016] I. In the current manual sampling method, the difficulty in accurately controlling the sampling depth leads to bottom-touching sampling or sampling positions that are too high, resulting in insufficient sample representativeness and affecting the accuracy and reliability of test results. This utility model uses the single reciprocating motion of the output end of the first cylinder to drive the lifting block, extension arm and sampling tube to complete the automatic descent and ascent action, thereby realizing automated sampling operation. This setting can accurately control the sampling depth of the sampling tube in the container, thereby ensuring that the sampled sample has higher representativeness and providing a guarantee for the accuracy and reliability of the test results.

[0017] Second, in this utility model, by setting the second cylinder, the lowest point of the reciprocating stroke of the output end of the first cylinder can be adjusted, thereby adjusting the sampling depth of the sampling tube according to containers of different depths and diameters, ensuring that the sampling depth is always in the optimal position; that is, the sampling height of the reciprocating lifting and lowering of the sampling tube can be adjusted according to the different depths of the container, so as to achieve the purpose of flexibly adjusting the sampling position of the equipment for different situations.

[0018] Third, in this utility model, an automatically opening and closing lid is provided on the container. Through the rapid opening and closing of the lid, it can work in conjunction with the sampling tube to achieve a faster sampling operation, shortening the time of manual operation of the lid opening and closing, thereby ensuring that the suspension can be sampled as soon as possible after the shaking ends.

[0019] Fourth, this utility model is equipped with a vibration function that drives the container to move back and forth in the horizontal direction, which can ensure the overall flow of the suspension and avoid the breakage of large particles caused by violent vortex oscillation. While ensuring the vibration effect, it can prevent the occurrence of excessive local shear force.

[0020] In summary, this invention can precisely control the sampling depth of the sampling tube within the container, ensuring higher representativeness of the sample and guaranteeing the accuracy and reliability of the test results; it can adjust the sampling depth of the sampling tube according to different container depths and diameters, keeping it in the optimal position at all times, enabling flexible adjustment of the sampling position for different situations; it works in conjunction with the sampling tube to achieve faster sampling, shortening operation time and ensuring that the suspension is sampled immediately after oscillation; it ensures the oscillation effect and avoids large particle breakage and excessive local shear force caused by violent vortex oscillation.

[0027] The following are specific implementation cases and appendices. Figures 1 to 5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0028] A sample oscillator for testing the turbidity of quartz sand includes a container 3 and a cover 4. The cover 4 is rotatably mounted on the container 3. A micro motor is installed on the cover 4, and the output end of the micro motor is connected to the cover 4. The micro motor controls the rotation of the cover 4 relative to the container 3 to control the opening and closing adjustment of the cover 4 at the container 3. This is existing technology. As long as the micro motor and its connection with the cover 4 meet the usage requirements, they are not limited or described in detail here. It also includes: a base 1, a PLC controller 2, a frame 5, a lifting block 6, an extension arm 7, a sampling tube 8, a sampling port 9, a first slider 10, and a first cylinder 11. The PLC controller 2 is installed on the front side of the upper surface of the base 1. The PLC controller 2 is a commonly used PLC controller on the market. It is existing technology and is a digital computing and operating electronic system specifically designed for use in industrial environments. It employs a programmable memory that stores instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations. It controls various types of mechanical equipment or production processes through digital or analog input / output. It uses a commercially available PLC controller capable of controlling the start / stop and processing of other commands for the electrical components in this application; it only needs to meet the usage requirements and will not be elaborated or limited here. The frame 5 is located on the rear side of the upper surface of the base 1; the lifting block 6 is slidably embedded in the inner cavity of the frame 5; the extension arm 7 is fixedly installed on the front side of the lifting block 6, and a through hole is opened at the front end of the extension arm 7; the sampling tube 8 is pluggably placed in the inner cavity of the through hole opened at the front end of the extension arm 7; the sampling port 9 is opened on the side wall of the sampling tube 8; the first slider 10 is fixedly installed on the rear side wall of the lifting block 6, and the first slider 10 slides through the rear side wall of the frame 5; the first cylinder 11 is located on the rear side wall of the frame 5, and the output end of the first cylinder 11 is connected to the lower surface of the first slider 10.

[0029] The PLC controller 2 controls the cover 4 to automatically open at the container 3, and controls the first cylinder 11 to start, driving the first slider 10, lifting block 6, extension arm 7, and sampling tube 8 to move down synchronously, so that the sampling tube 8 gradually extends into the solution in the container 3. The solution after shaking enters the inner cavity of the sampling tube 8 through the sampling port 9, completing the sampling of the shaken solution. After sampling, the sampling tube 8 moves synchronously under the upward action of the output end of the first cylinder 11 until the sampling tube 8 is completely separated from the shaken suspension in the container 3. During the sampling process, when the sampling tube 8 moves down to the lowest point, it always maintains a sufficient distance from the bottom of the inner wall of the container 3.

[0030] In this invention, the single reciprocating motion of the output end of the first cylinder 11 drives the lifting block 6, the extension arm 7, and the sampling tube 8 to complete automatic lifting actions, thereby realizing automated sampling. This setting can precisely control the sampling depth of the sampling tube 8 in the container 3, thereby ensuring that the sample taken has higher representativeness and laying the foundation for the accuracy and reliability of the test results.

[0031] The solution also includes: a platform 12 and a second cylinder 13. The platform 12 is fixedly installed at the bottom of the frame 5, and the first cylinder 11 is fixedly installed on the platform 12; the second cylinder 13 is fixedly installed on the rear side wall of the base 1, and the output end of the second cylinder 13 is fixedly connected to the lower surface of the platform 12.

[0032] When the depth specification of container 3 changes, the height of sampling tube 8 when it descends to the lowest point needs to be adjusted: the second cylinder 13 is moved by the PLC controller 2, so that the platform 12 drives the first cylinder 11, the frame 5, and the sampling tube 8 to adjust in the vertical direction, thereby adjusting the height of sampling tube 8 when it descends to the inner cavity of container 3 without changing the reciprocating stroke length of the output end of the first cylinder 11.

[0033] Two movable blocks 14 are symmetrically installed on the left and right sides of the platform 12. A guide rod 15 is provided through the movable block 14 in the vertical direction. The guide rod 15 is fixed and vertically installed on the base 1. When the platform 12 moves, it can drive the movable block 14 to move in the vertical direction along the guide rod 15, thereby further guiding the vertical lifting displacement of the platform 12.

[0034] This solution also includes: a slide groove 16 and a second slider 17. The slide groove 16 is vertically opened on the left and right sides of the frame 5. There are two second sliders 17, and the two second sliders 17 are respectively installed on the left and right sides of the lifting block 6. The second sliders 17 are slidably embedded in the inner cavity of the slide groove 16. During the lifting and lowering movement of the lifting block 6, the second sliders 17 can be moved along the inner cavity of the slide groove 16, thereby further guiding the lifting and lowering movement of the lifting block 6.

[0035] This solution also includes: a motor 18, a drive shaft 19, a turntable 20, a drive pin 21, a movable frame 22, and a connecting seat 25. The motor 18 is mounted on the lower surface of the base 1; the drive shaft 19 is fixedly mounted on the output end of the motor 18; the turntable 20 is fixedly mounted on the drive shaft 19; the drive pin 21 is rotatably mounted on the upper surface of the turntable 20, and the drive pin 21 is eccentrically positioned relative to the turntable 20; the movable frame 22 is slidably sleeved on the drive pin 21, and the movable frame 22 is movably positioned in the horizontal direction; the connecting seat 25 is fixedly mounted on the side wall of the movable frame 22. Furthermore, after a suitable period of oscillation, the output end of the motor 18 is controlled by the PLC controller 2 to rotate to the initial position and then stop. In this state, the container 3 is directly below the sampling tube 8.

[0036] After the motor 18 is turned on, the drive shaft 19 and the turntable 20 can rotate synchronously in a circumferential direction, which in turn causes the drive pin 21 to drive the moving frame 22 to move back and forth in the horizontal direction. At the same time, the third slider 23 is driven to slide along the inner cavity of the limiting groove 24, and finally the moving seat 26 and the sampling solution in the inner cavity of the container 3 which has been positioned at its top are shaken and mixed.

[0037] This solution also includes: a movable base 26, a fixed plate 27, a connecting arm 28, and a third cylinder 29. The movable base 26 is fixedly installed on the connecting base 25, and the movable base 26 has a hole for placing the container 3. There are two fixed plates 27, which are symmetrically installed on the movable base 26. There are two connecting arms 28, one of which is fixedly installed on one of the fixed plates 27, and the other connecting arm 28 slides through the side wall of the other fixed plate 27. The third cylinder 29 is fixedly installed on the movable base 26, and the output end of the third cylinder 29 is fixedly connected to the other connecting arm 28. The container 3 is positioned between the two third cylinders 29. The movable base 26 is placed at the hole on the movable base 26, and the connected connecting arm 28 and the third cylinder 29 are moved by the activated third cylinder 29 to achieve the clamping and positioning of the container 3 between the two third cylinders 29.

[0038] The movable frame 22 is equipped with a third slider 23 at its front and rear ends respectively. The base 1 has a limit groove 24 on its front and rear inner walls respectively. The third slider 23 is slidably embedded in the inner cavity of the limit groove 24. The movement of the movable frame 22 drives the third slider 23 to move along the inner cavity of the limit groove 24, so as to limit the displacement of the movable frame 22 in the horizontal direction.

[0039] Specifically, the PLC controller 2 is electrically connected to the first cylinder 11, the second cylinder 13, and the third cylinder 29. The first cylinder 11, the second cylinder 13, and the third cylinder 29 used in this application are commonly available self-locking cylinders. Their output ends can stop at any position and lock. The output end of the first cylinder 11 can reciprocate downward and upward under the control of the PLC controller 2, driving the sampling tube 8 to descend into the inner cavity of the container 3 for sampling and then rising again, thus completing one automated sampling operation. The first cylinder 11, the second cylinder 13, and the third cylinder 29 are existing commercially available models that meet the above-mentioned usage requirements; therefore, they will not be elaborated upon or limited here.

[0040] In addition, motor 18 is a commonly used self-locking motor with a lockable output end. When it stops, the output end can lock itself and will not rotate under external force. Motor 18 is also a commonly used forward and reverse motor, and its output end can rotate in the forward or reverse direction according to the usage requirements. Furthermore, the initial position of motor 18 can be set through the settings of PLC controller 2, and the motor 18 can be stopped and automatically returned to the initial position by the output end. The initial position of motor 18 can control container 3 to be directly below sampling tube 8. This is existing technology, which can meet the above usage requirements, and will not be described or limited here.

[0041] The working principle of a sample oscillator for turbidity testing of quartz sand in this embodiment is as follows:

[0042] First, position the container 3 on the movable seat 26: place the movable seat 26 at the hole on the movable seat 26, and use the activated third cylinder 29 to drive the connecting arm 28 and the third cylinder 29 connected to it to move, so as to achieve the clamping and positioning of the container 3 between the two third cylinders 29.

[0043] The motor 18 drives the drive shaft 19 and turntable 20 to rotate synchronously in the circumferential direction, so that the drive pin 21 drives the moving frame 22 to move back and forth in the horizontal direction. At the same time, it drives the third slider 23 to slide along the inner cavity of the limiting groove 24, thereby driving the moving seat 26 and the sampling solution in the inner cavity of the container 3 after its top is positioned to be shaken and mixed.

[0044] After a suitable period of vibration, the output of motor 18 is controlled by PLC controller 2 to rotate to the initial position and then stop. In this state, container 3 is directly below sampling tube 8. PLC controller 2 controls the cover 4 to automatically open at container 3 and controls the first cylinder 11 to automatically open and drive the first slider 10, lifting block 6, extension arm 7, and sampling tube 8 to move down synchronously. Sampling tube 8 gradually extends into the solution inside container 3. The vibrationd solution enters the inner cavity of sampling tube 8 through sampling port 9 to achieve sampling of the vibrationd solution. After sampling, sampling tube 8 moves synchronously under the action of the upward movement of the output of first cylinder 11 until sampling tube 8 is completely separated from the suspension after vibration treatment in container 3 for sampling. During the sampling process, when sampling tube 8 moves down to the lowest point, it is ensured that there is still a sufficient distance between it and the bottom of the inner wall of container 3.

[0045] If the depth specification of container 3 changes, the height of sampling tube 8 when it descends to the bottom point needs to be adjusted: the second cylinder 13 is moved by the PLC controller 2, so that the platform 12 drives the first cylinder 11 and the frame 5 and sampling tube 8 to make vertical adjustment. Thus, the height of sampling tube 8 when it descends to the inner cavity of container 3 can be adjusted without changing the reciprocating stroke length of the output end of the first cylinder 11.

[0046] This invention can precisely control the sampling depth of the sampling tube 8 within the container 3, ensuring that the sample taken has higher representativeness and guaranteeing the accuracy and reliability of the test results; it can adjust the sampling depth of the sampling tube 8 according to different depths and diameters of the container 3, keeping it in the optimal position at all times, and flexibly adjusting the sampling position of the equipment for different situations; it works in conjunction with the sampling tube 8 to achieve faster sampling, shorten operation time, and ensure that the suspension is sampled immediately after the oscillation ends; it ensures the oscillation effect and avoids the breakage of large particles and excessive local shear force caused by violent vortex oscillation.
