Description

Technical Field

[0001] The utility model belongs to the technical field of sediment measurement, and particularly relates to an electronic sediment measuring instrument. Background Technique

[0002] At present, in the technology of analyzing the sediment content of water samples, the most widely used method is the drying and weighing method. That is, first, the volume V of the water sample to be measured is measured by tools such as a graduated cylinder, and then the sediment in the water sample to be measured is filtered out by using a filter paper, etc. Then, the filtered sediment is dried and weighed to obtain the sediment mass Ms, and the sediment content Cj of the water sample can be calculated (Cj = Ms / V). However, in actual operation, the volume V is often measured by manual reading. The water sample in the graduated cylinder is manually poured into the filtering device for filtration, the filtered sediment is manually transferred to the drying device for drying, and the dried sediment is manually transferred to the weighing device for weighing. In the whole process, the labor intensity and operation difficulty of manual work are relatively high, and the manual reading plus the back-and-forth transfer of the water sample between multiple devices result in a relatively large measurement error and inaccurate measurement results, which need to be improved. Content of the Utility Model

[0003] In view of this, the purpose of the utility model is to provide an electronic sediment measuring instrument, which can realize the automatic measurement, automatic flipping filtration, drying and weighing of the volume of the water sample to solve the above problems.

One end of a first rotating shaft far away from the other first rotating shaft is drivingly connected with a first motor. A material cylinder is fixedly connected between the two first rotating shafts. The top of the material cylinder is open, and a jacket is fixedly sleeved on the outside. A heating resistance wire is wound around the jacket. On the front and back sides outside the jacket, first hydraulic cylinders are vertically and fixedly arranged. The piston rods of the two first hydraulic cylinders face upwards and are detachably connected to the same cylinder cover. The cylinder cover includes an annular support ring plate. The support ring plate can abut against the top of the material cylinder and a filter cloth is fixedly arranged on the inner side thereof. On the upper part outside one of the supports, a second motor is fixedly arranged. The output shaft of the second motor faces upwards and is fixedly connected with a cross plate. A liquid level sensor is fixedly arranged at the tail end of the bottom of the cross plate. The liquid level sensor can be located above the material cylinder. On the lower parts of the two supports, second rotating shafts are horizontally and rotatably arranged. One end of a second rotating shaft far away from the other second rotating shaft is drivingly connected with a third motor. A flipping plate is fixedly connected between the two second rotating shafts. A water tank is placed on the top of the flipping plate, and a weighing sensor is fixedly arranged at the bottom.

[0009] Preferably, the base is made of aluminum foam.

[0010] Preferably, a rubber anti-slip pad is fixedly provided on the bottom of the base.

[0011] The beneficial effects of the present utility model are as follows: When detecting the sediment content of a water sample, the water sample can be first poured into the material cylinder, and then the second motor is operated to drive the cross plate to rotate 180 degrees, so that the liquid level sensor can be turned above the material cylinder, and thus the liquid level of the water sample in the material cylinder can be measured by the liquid level sensor, and the measured liquid level information is fed back to the control center. Since the inner bottom area of the material cylinder is known, the volume V of the water sample can be calculated. Then, the second motor is operated again to drive the cross plate to reverse 180 degrees, so that the cross plate and the liquid level sensor can be reset without affecting subsequent operations.

Then, the circuit of the heating resistance wire is connected to heat the material cylinder, and the drying treatment of the sediment can be realized. After drying is completed, first remove the water tank on the turning plate, and then operate the third motor. Through the cooperation of the second rotating shaft, drive the turning plate to turn 180 degrees, and the weighing sensor and the tray can be turned upward. Then, operate the first hydraulic cylinder to extend its piston rod, and the whole cylinder cover can be driven to move downward until the cylinder cover is placed on the tray. After that, through the detachable connection between the cylinder cover and the piston rod of the first hydraulic cylinder, the cylinder cover can be separated from the piston rod of the first hydraulic cylinder, and then the piston rod of the first hydraulic cylinder is reset, and the total weight of the cylinder cover and the sediment on it can be measured by the weighing sensor and the weight information is fed back to the control center. Since the weight of the cylinder cover is known, the weight Ms of the sediment can be calculated, and then according to the formula Cj = Ms / V, the sediment content Cj of the measured water sample can be calculated. In this way, during the whole detection process, there is no need to measure the volume of the water sample by manual reading through a measuring cylinder, making the measurement of the volume of the water sample more accurate. And for subsequent filtration, drying and weighing, there is no need to load and unload and transfer the water sample back and forth, making the measurement of the weight of the sediment more accurate. Furthermore, the result of the sediment content of the water sample finally obtained is more accurate, with smaller errors, and there is no need for frequent manual back-and-forth operations, which can effectively reduce the labor intensity and operation difficulty of the staff and is more convenient and practical.

Specific embodiments

[0021] The following further describes the present utility model in detail with reference to the drawings and specific embodiments:

On the left and right ends of the top of the base 1, there are vertically fixed supports 2. On the upper parts of the two supports 2, there are horizontally and rotatably arranged first rotating shafts 3. One end of a first rotating shaft 3 far from the other first rotating shaft 3 is drivingly connected to a first motor 4. Between the two first rotating shafts 3, there is a fixed connection with a material cylinder 5. The top of the material cylinder 5 is open, and an outer side thereof is fixedly sleeved with a jacket 6. A heating resistance wire 7 is wound in the jacket 6. On the front and rear sides outside the jacket 6, there are vertically fixed first hydraulic cylinders 8. The piston rods of the two first hydraulic cylinders 8 face upward and are detachably connected to the same cylinder cover 9. The cylinder cover 9 includes an annular support ring plate 10. The support ring plate 10 can abut against the top of the material cylinder 5, and a filter cloth 11 is fixedly arranged on the inner side thereof. On the upper outer side of a support 2, there is fixedly arranged a second motor 12. The output shaft of the second motor 12 faces upward and is fixedly connected to a cross plate 13. On the bottom end of the cross plate 13, there is fixedly arranged a liquid level sensor 14. The liquid level sensor 14 can be located above the material cylinder 5. On the lower parts of the two supports 2, there are horizontally and rotatably arranged second rotating shafts 15. One end of a second rotating shaft 15 far from the other second rotating shaft 15 is drivingly connected to a third motor 16. Between the two second rotating shafts 15, there is a fixed connection with a turning plate 17. A water tank 18 is placed on the top of the turning plate 17, and a weighing sensor 19 is fixedly arranged on the bottom. A tray 20 is fixedly arranged at the bottom of the weighing sensor 19. On the top of the base 1, there is a control center 21. The first motor 4, the heating resistance wire 7, the hydraulic cylinder 8, the second motor 12, the liquid level sensor 14, the third motor 16, and the weighing sensor 19 are all electrically connected to the control center 21;

[0023] When detecting the sediment content of a water sample, the water sample can be first poured into the material cylinder 5. Then, the second motor 12 is operated to drive the cross plate 13 to rotate 180 degrees, so that the liquid level sensor 14 can be turned above the material cylinder 5. Thus, the liquid level of the water sample in the material cylinder 5 can be measured by the liquid level sensor 14, and the measured liquid level information is fed back to the control center 21. Since the inner bottom area of the material cylinder 5 is known, the volume V of the water sample can be calculated. Next, the second motor 12 is operated again to drive the cross plate 13 to reverse 180 degrees, so that the cross plate 13 and the liquid level sensor 14 can be reset without affecting subsequent operations. After that, the first hydraulic cylinder 8 is operated to contract its piston rod until the support ring plate 10 of the cylinder cover 9 presses against the top of the material cylinder 5. Then, the first motor 4 is operated, and through the cooperation of the first rotating shaft 3, the material cylinder 5 and the cylinder cover 9 can be integrally turned 180 degrees to make the cylinder cover 9 face downward. And during the turning process, the water in the water sample can flow out through the filter cloth 11 and be received by the water tank 18, and the sediment in the water sample can be blocked by the filter cloth 11 on the upper surface of the filter cloth 11 at this time, realizing the automatic filtration of the water sample. Then, the circuit of the heating resistance wire 7 is connected to heat the material cylinder 5, and the drying treatment of the sediment can be realized. After drying is completed, first remove the water tank 18 on the turning plate 17, and then operate the third motor 16. Through the cooperation of the second rotating shaft 15, drive the turning plate 17 to turn 180 degrees, and the weighing sensor 19 and the tray 20 can be turned upward. Next, operate the first hydraulic cylinder 8 to extend its piston rod, which can drive the cylinder cover 9 to move downward as a whole until the cylinder cover 9 is placed on the tray 20. After that, through the detachable connection between the cylinder cover 9 and the piston rod of the first hydraulic cylinder 8, the cylinder cover 9 can be separated from the piston rod of the first hydraulic cylinder 8, and then the piston rod of the first hydraulic cylinder 8 is reset. The total weight of the cylinder cover 9 and the sediment on it can be measured by the weighing sensor 19, and the weight information is fed back to the control center 21. Since the weight of the cylinder cover 9 is known, the weight Ms of the sediment can be calculated. Then, according to the formula Cj = Ms / V, the sediment content Cj of the measured water sample can be calculated. In this way, during the whole detection process, there is no need to manually read the volume of the water sample through a measuring cylinder, making the measurement of the volume of the water sample more accurate. And for subsequent filtration, drying and weighing, there is no need to load and unload and transfer the water sample back and forth, making the measurement of the weight of the sediment more accurate. Furthermore, the result of the sediment content of the water sample finally obtained is more accurate, with less error, and there is no need for manual operation back and forth frequently, which can effectively reduce the labor intensity and operation difficulty of the staff and is more convenient and practical. The first motor 4, the heating resistance wire 7, the first hydraulic cylinder 8, the filter cloth 11, the second motor 12, the liquid level sensor 14, the third motor 16, the weighing sensor 19 and the control center 21 can all adopt existing technologies. And among them, the first motor 4, the second motor 12 and the third motor 16 can specifically adopt existing conventional stepping motors with a brake function to cooperate to realize the rotation of the corresponding angle and the position locking after rotation in place. The liquid level sensor 14 can specifically adopt an existing conventional non-contact liquid level sensor.

A positioning box 24 is fixedly provided on the bottom of the corresponding support ring plate 10 of the positioning block 22. The bottom of the positioning box 24 is open, and a limiting blind hole 25 is provided on the inner wall of the side away from the material cylinder 5.

[0025] So that during the detection operation, the second hydraulic cylinder 23 is also electrically connected to the control center 21. After the dried cylinder cover 9 is placed on the tray 20, the second hydraulic cylinder 23 can be operated first to contract its piston rod until it completely withdraws from the corresponding limiting blind hole 25, and then the first hydraulic cylinder 8 is operated to contract its piston rod, so that it can be lifted out of the positioning box 24 with the positioning block 22, so that the cylinder cover 9 is separated from the piston rod of the first hydraulic cylinder 8, which is convenient for subsequent weighing. When the cylinder cover 8 needs to be reinstalled, it only needs to align the two positioning boxes 24 on the cylinder cover 8 with the two positioning blocks 22 and insert them in place, and then operate the second hydraulic cylinder 23 to extend its piston rod and insert it in place in the corresponding limiting blind hole 25 to insert and fix the positioning box 24, thus completing the fixed installation of the cylinder cover 9, and the installation is stable and does not affect subsequent use. In this way, the convenient disassembly and assembly of the cylinder cover 9 can be realized, which is more convenient for cooperating with the detection operation and cleaning and replacing the filter cloth 11 on the cylinder cover 9, so as not to affect the subsequent detection operation and is more practical.
