Description

Technical Field

[0001] The invention relates to the technical field of measuring suspended matter and sediment in water, and more specifically to a filtering and weighing device for suspended matter and sediment in water. Background Art

[0002] Suspended matter and sediment in water refer to solid matter that is retained on the filter membrane after the water sample passes through a filter membrane with a pore size of 0.45um and is dried to constant weight at 103-105℃. Excessive suspended matter and sediment in surface water can easily make the water turbid, reduce transparency, and affect the metabolism of aquatic organisms. Industrial circulating cooling water and boiler water contain a lot of suspended matter, which can easily cause the inner diameter of the water pipe to narrow, increase pipeline pressure, reduce water delivery, and easily cause nozzle blockage at the end of water use, reducing process cooling effect, and ultimately affecting product quality. Due to the special harmful effects of suspended matter in water, various environmental testing agencies and production water process flows have made suspended matter in water a must-check and strictly monitored indicator.

[0003] Currently, there is only one environmental monitoring method for determining the suspended matter content in water quality, which is numbered GB11901-1989 "Gravimetric Method for Determination of Suspended Matter in Water Quality". The basic principle of the gravimetric method is to intercept the suspended matter in the water sample on the filter membrane through a filtering device, and then dry the filter membrane and the intercepted suspended matter to constant weight. The mass of the suspended matter is obtained by weighing, and then converted into the concentration of the suspended matter in the water sample. The manual analysis method is adopted, and the constant weight process of the filter membrane after filtration is very cumbersome. The filter membrane before and after filtration needs to be dried and weighed many times to ensure that the measurement results are relatively accurate. Different equipment is used for drying and weighing. The measuring personnel need to transfer the filter membrane before and after filtration many times, and the moisture on the filter membrane after filtration only depends on the drying equipment for drying, which takes a long time. The determination of suspended matter and sediment in water is time-consuming and laborious. In view of this, we propose a filtering and weighing device for suspended matter and sediment in water. Summary of the invention

[0021] 4. The present invention adopts the structural design of the water pressure mechanism, so that when the connecting shaft drives the reverse ring to rotate in the forward direction, the reverse ring drives the column and the forward ring to rotate in the forward direction as a whole through the limit column B, so that the connecting shaft drives the adjusting shaft and the movable ring block to rotate at the same time, the shape of the water pressure component remains unchanged, and the overall rotation is used to pressurize water for the filter membrane.

After the plug-in arc block is plugged into the plug-in arc groove, when the water pressurizing assembly rotates as a whole to press water, the column drives the inner gear ring to rotate, so that the planetary gear drives the outer gear ring, the connecting ring and the rotating plug-in arc block to rotate, so that the weighing bottle drives the mounting plate to rotate along the top plate through the plug-in block, thereby further improving the water pressurizing efficiency, further saving the measurement time of suspended matter and sediment in water, and further solving the technical problem of time-consuming and labor-intensive measurement of suspended matter and sediment in water.

[0054] In an embodiment of the present invention, the water pressure mechanism 6 includes a mounting seat 61, which is fixedly mounted on the movable end of the lifting mechanism 5. A motor 62 is fixedly mounted on the top of the mounting seat 61, and a contact ring block 68 is fixedly mounted on the bottom of the mounting seat 61.

The top end of the planetary disk 63 is fixedly connected to the bottom end of the mounting seat 61. A rotating hole 69 is opened at the center position of the planetary disk 63. A limited rotating groove A60 is opened in the middle of the rotating hole 69. A water pressure component 64 is rotatably arranged on the rotating hole 69. The water pressure component 64 is movably connected to the limited rotating groove A60 through a forward rotating component 65. An adjusting component 66 is arranged on the top of the water pressure component 64. The adjusting component 66 is movably connected to the water pressure component 64 through a reverse rotating component 67.

[0055] In the embodiment of the present invention, the water pressure assembly 64 includes a column 641 and a plurality of mounting strips 645. The column 641 is rotatably arranged at the center of the planetary disk 63. The bottom end of the column 641 is provided with a plurality of mounting grooves A642 in an annular structure with equal spacing. The top end of the column 641 is provided with a movable hole 643. The top of the movable hole 643 is provided with a limited rotation groove B640. The bottom end of the movable hole 643 is provided with a plurality of slide grooves 644 in an annular structure with equal spacing. The plurality of mounting strips 645 are provided with a plurality of slide grooves 644. 4 is arranged at the outer side of the column 641, and the centripetal end of the installation block 645 is provided with three installation grooves B646 in a linear structure, and the installation groove B646 is rotatably connected with a connecting rod 647 through a rotating rod A, and the two connecting rods 647 at the bottom are rotatably connected with both ends of the installation groove A642 through a rotating rod B, and the eccentric end of the installation block 645 is provided with a rotating groove 648, and a water pressure shaft 649 is arranged in the rotating groove 648, and the top of the water pressure shaft 649 is rotatably connected with the top of the rotating groove 648 through a rotating rod C;

[0056] A plurality of groups of ball grooves 6481 are provided at both ends of the rotating groove 648, and each group of ball grooves 6481 includes a plurality of equally spaced arc-shaped structures. Balls 6482 are movably provided in the ball grooves 6481, and the ball 6482 is movably connected to the water pressure shaft 649. Fig.13 and Fig.14It can be seen that the bottom end of the water pressurizing shaft 649 can pass through the rotating groove 648, so that the water pressurizing shaft 649 can fit with the bottom end of the pressing film 73 as much as possible, thereby increasing the water pressurizing space of the water pressurizing shaft 649, and spherical body 6482 is movably arranged in the ball groove 6481 to provide support force for the water pressurizing shaft 649 and reduce the force on the rotating rod C. Moreover, the spherical body 6482 can rotate in the ball groove 6481 without affecting the self-rotation of the water pressurizing shaft 649.

[0057] In an embodiment of the present invention, the forward rotating component 65 includes a forward ring 651, which is rotatably arranged on the limit rotation groove A60, and the forward ring 651 is fixedly connected to the column 641. A plurality of forward grooves 652 are provided on the forward ring 651 in a circular equidistant structure. The depth of the forward grooves 652 gradually decreases in the clockwise direction. The forward grooves 652 are adapted to the shape of the limit rotation groove A60. The gap between the forward grooves 652 and the limit rotation groove A60 constitutes a reverse limit cavity. A limit column A653 is movably arranged in the reverse limit cavity. The limit column A653 is elastically connected to the deep part of the forward groove 652 by a spring A654. Through the above-mentioned arrangement, the present invention enables, in a static state, due to the elastic force of the spring A654, the limit column A653 is located in the middle position of the reverse limit cavity, so that when the forward ring 651 rotates in the forward direction, under the friction force of the limit rotation groove A60, the limit column A653 has the force to move toward the deep part of the reverse limit cavity, and has little effect on the forward rotation of the forward ring 651. When the forward ring 651 rotates in the reverse direction, the limit column A653 has the force to move toward the shallow part of the reverse limit cavity, so that the limit rotation groove A60 locks the forward ring 651 through the limit column A653, and therefore, the forward ring 651 cannot rotate in the reverse direction.

[0058] In the embodiment of the present invention, the adjustment assembly 66 includes a movable ring block 661, which is movably arranged on the movable hole 643, and a plurality of slide seats 662 are fixedly arranged on the outer edge surface of the movable ring block 661, and the plurality of slide seats 662 are respectively slidably connected with the plurality of slide grooves 644, and the number of the plurality of slide seats 662 is equal to the number of the plurality of mounting strips 645, and the connecting rod 647 at the top is rotatably connected with the slide seat 662 through the rotating rod D, and the movable ring block 661 is provided with an adjustment shaft 66 3. The bottom end of the adjusting shaft 663 is rotatably connected to the bottom end of the movable hole 643. A connecting shaft 664 is fixedly arranged at the top end of the adjusting shaft 663. The connecting shaft 664 is rotatably connected to the movable hole 643. The top end of the connecting shaft 664 passes through the planetary disk 63 and the mounting seat 61 in sequence and is fixedly connected to the output shaft of the motor 62. A lifting guide groove 665 is provided on the surface of the adjusting shaft 663. A guide ball block 666 is movably connected to the lifting guide groove 665. The guide ball block 666 is fixedly connected to the inner edge surface of the movable ring block 661.

[0059] The lifting guide groove 665 includes two partial thread grooves 6651 arranged in a symmetrical structure, and both ends of the two partial thread grooves 6651 are connected through the arc guide groove 6652. Through the above arrangement, the present invention enables the output shaft of the motor 62 to rotate, and the connecting shaft 664 is driven to rotate, so that the adjustment shaft 663 rotates. When the adjustment shaft 663 and the movable ring block 661 rotate relative to each other, the guide ball block 666 moves in the lifting guide groove 665, and the guide ball block 666 moves in one of the partial thread grooves 6651, so that the movable ring block 661 drives the slide 662 to slide upward along the slide groove 644. When the guide ball block 666 moves in the lifting guide groove 665, the movable ring block 661 drives the slide 662 to slide downward along the slide groove 644. When the guide ball block 666 moves in the arc guide groove 6652, the movable ring block 66 1 position remains stationary, the sliding seat 662 slides to drive the connecting rod 647 located above to move, so that all the installation blocks 645 drive the water pressure shaft 649 to expand and contract. It is worth noting that when the guide ball block 666 is located in the upper arc guide groove 6652, the distance between the water pressure shaft 649 and the column 641 is the smallest, which is suitable for taking the water pressure shaft 649 out of the weighing bottle 71 or putting it down. When the guide ball block 666 is located in the lower arc guide groove 6652, the distance between the water pressure shaft 649 and the column 641 is the largest. At this time, the water pressure shaft 649 can be squeezed and contacted with the pressure film 73. The setting of the arc guide groove 6652 makes the adjustment of the water pressure assembly 64 simpler.

[0060] In an embodiment of the present invention, the reverse rotation component 67 includes a reverse ring 671, which is rotatably arranged on the limit rotation groove B640, and the reverse ring 671 is fixedly connected to the connecting shaft 664. A plurality of reverse grooves 672 are provided on the reverse ring 671 in a ring-shaped and evenly spaced structure. The groove depth of the reverse groove 672 gradually decreases in the counterclockwise direction. The reverse groove 672 is adapted to the shape of the limit rotation groove B640. The gap between the reverse groove 672 and the limit rotation groove B640 constitutes a forward limit cavity. A limit column B673 is movably arranged in the forward limit cavity. The limit column B673 is elastically connected to the deep part of the reverse groove 672 by a spring B674. Through the setting of the reverse rotation component 67 of the present invention and in combination with the principle of the forward rotation component 65, it can be known that the reverse ring 671 cannot rotate forwardly relative to the limiting groove B640. Therefore, when the connecting shaft 664 drives the reverse ring 671 to rotate forwardly, the reverse ring 671 drives the column 641 and the forward ring 651 to rotate forward as a whole through the limiting column B673, so that the connecting shaft 664 drives the adjusting shaft 663 and the movable ring block 661 to rotate simultaneously, and the shape of the water pressure component 64 remains unchanged, and the whole rotates to pressurize the water of the filter membrane 72. When the connecting shaft 664 drives the reverse ring 671 to rotate reversely, the forward ring 651 does not rotate, and the connecting shaft 664 drives the adjusting shaft 663 and the movable ring block 661 to rotate relative to each other, which is used for the shape adjustment of the water pressure component 64.

[0061] In the embodiment of the present invention, a rotating ring 631 is rotatably connected to the outer edge surface of the planetary disk 63, an inner gear ring 632 is fixedly provided at the bottom end of the rotating ring 631, an outer gear ring 633 is provided inside the inner gear ring 632, the outer gear ring 633 is fixedly connected to the column 641, the inner gear ring 632 and the outer gear ring 633 are meshed and connected through a plurality of planetary gears 634 arranged in an annular equidistant structure, the planetary gear 634 is rotatably connected to the bottom end of the planetary disk 63 through a rotating rod E, a connecting ring 635 is fixedly provided at the bottom end of the planetary gear 634, a plurality of plug-in arc blocks 636 are fixedly provided at the bottom end of the connecting ring 635 in an annular equidistant structure, and the plug-in arc blocks 636 are plugged and matched with the plug-in arc grooves 74;

[0062] Among them, the arc of the plug-in arc block 636 is smaller than the arc of the plug-in arc groove 74. The present invention further sets the water pressure mechanism 6, and sets the arc of the plug-in arc block 636 to be smaller than the arc of the plug-in arc groove 74, so as to facilitate the plug-in arc block 636 and the plug-in arc groove 74. After the plug-in arc block 636 and the plug-in arc groove 74 are plugged, when the water pressure assembly 64 rotates as a whole to press water, the column 641 drives the inner gear ring 632 to rotate, so that the planetary gear 634 drives the outer gear ring 633, the connecting ring 635 and the rotating plug-in arc block 636 to rotate, so that the weighing bottle 71 drives the mounting plate 40 to rotate along the top plate 41 through the plug-in block 75, thereby further improving the water pressure efficiency, further saving the measurement time of suspended matter and sediment in the water body, and further solving the technical problem of time-consuming and labor-intensive measurement of suspended matter and sediment in the water body.

[0063] A method for using a device for filtering and weighing suspended matter and sediment in a water body, comprising the following steps:

[0064] S1: Place the filter membrane 72 into the weighing bottle 71 so that the outer edge of the filter membrane 72 contacts the inner edge of the weighing bottle 71, place the pressing film 73 into the filter membrane 72, and place the weighing bottle 71 on the top of the mounting mechanism 4 so that the plurality of plug-in blocks 75 are respectively plugged into the plurality of plug-in cavities 44, and the sharp corners at the bottom of the plug-in blocks 75 can provide a guiding effect during the plug-in process;

[0065] S2: Record the weight reading on the weighing mechanism 3, recorded as A, then A is the weight (g) of the filter membrane 72 + the pressing membrane 73 + the weighing bottle 71 + the mounting mechanism 4, and B is the weight (g) of the filter membrane 72 + the pressing membrane 73 + the weighing bottle 71 + the mounting mechanism 4;

[0066] S3: Using a tool to remove the pressed film 73;

[0067] S4: Pour the water sample to be measured into the weighing bottle 71, and the water sample is filtered by the filter membrane 72. The water flows out from the bottle wall of the weighing bottle 71 through the filter membrane 72 to the drainage cavity surrounded by the vertical ring 23, the installation ring 22 and the gap of the drying tube 21, and is discharged from the drainage pipe 24. The suspended matter and sediment are retained on the filter membrane 72;

[0068] S5: Use a tool to place the pressing film 73 into the filter membrane 72 so that the outer edge surface of the pressing film 73 contacts the inner edge surface of the filter membrane 72;

[0069] S6: The output shaft of the motor 62 is controlled to rotate in reverse through an external control mechanism, so that the connecting shaft 664 drives the adjusting shaft 663 and the movable ring block 661 to rotate relative to each other, and the guide ball block 666 moves in one of the partial thread grooves 6651, so that the movable ring block 661 drives the slide 662 to slide upward along the slide groove 644 until the guide ball block 666 moves to the arc guide groove 6652 located below, and the movable ring block 661 remains in position. The upward sliding of the slide 662 drives the connecting rod 647 located above to move, so that all the installation strips 645 drive the water pressure shaft 649 to contract in the centripetal direction.

[0070] S7: The lifting mechanism 5 is controlled to descend through an external control mechanism, so that a number of installation blocks 645 and the water pressure shaft 649 enter the weighing bottle 71, the plug-in arc block 636 is inserted into the plug-in arc groove 74, and the bottom end of the contact ring block 68 contacts the top end of the drying tube 21. The output shaft of the motor 62 is controlled by the external control mechanism to rotate in the opposite direction, so that the guide ball block 666 moves to the arc guide groove 6652 located above. As can be seen from the principle of S6, the installation block 645 drives the water pressure shaft 649 to open in the eccentric direction, and the surface of the water pressure shaft 649 contacts the pressure film 73 to prevent the water pressure shaft 649 from bringing out suspended matter and sediment during the water pressure process, thereby ensuring the accuracy of the measurement results.

[0071] S8: The output shaft of the motor 62 is controlled to rotate in the forward direction through the external control mechanism, so that the connecting shaft 664 rotates together with the column 641, so that the water-pressing shaft 649 rolls along the surface of the pressing film 73, presses water on the filter membrane 72, and reduces the moisture content of the filter membrane 72. At the same time, the inner gear ring 632 drives the connecting ring 635 to rotate in the opposite direction relative to the connecting shaft 664, so that the filter mechanism 7 rotates to improve the water-pressing efficiency. After the water-pressing is completed, all the installation blocks 645 are controlled to drive the water-pressing shaft 649 to shrink in the centripetal direction, so that the water-pressing shaft 649 is separated from the pressing film 73. It is worth mentioning that the water-pressing shaft 649 shrinks at an oblique upward angle in the centripetal direction, which will not affect the subsequent weighing;

[0072] S9: The external control mechanism controls the motor 62 to control the drying mechanism 2, so that the drying tube 21 dries the filter mechanism 7, and observes and records the weight reading B on the weighing mechanism 3 at fixed intervals. The weight reading B is the weight (g) of the suspended matter and sediment + filter membrane 72 + pressing membrane 73 + weighing bottle 71 + mounting mechanism 4. If the values ​​of the two weight readings B differ greatly, the water pressing mechanism 6 can be used repeatedly to press water, and then dry until the weight difference between the two weighings is ≤0.4mg;

[0073] S10: Take the last recorded weight reading B and calculate the measurement result according to the formula C=(BA)×1000 / V, where C is the concentration of suspended matter and sediment in water (mg / L) and V is the sample volume (mL).

[0074] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
