Description

Technical Field

[0001] The invention relates to the technical field of chemical wastewater detection, and in particular to a safe sampling device for chemical wastewater detection. Background Art

[0002] Pure water changes its original physical or chemical properties after use and becomes wastewater containing different types of impurities. If these wastewaters are discharged without treatment, they will cause different properties and varying degrees of pollution in the water body, thereby endangering human health and affecting industrial and agricultural production. Chemical wastewater needs to be sampled and tested after treatment.

[0003] When sampling chemical wastewater, mechanical sampling is generally used instead of manual sampling to avoid the safety hazards of manual sampling. However, after sampling the chemical wastewater through mechanical equipment, when the staff takes out the chemical wastewater samples inside the mechanical equipment, because the mechanical equipment is deep in the chemical wastewater, a small amount of chemical wastewater is attached to its outside and in the gaps where it is connected to the outside world. This part of wastewater can easily cause damage to the staff when they take out the samples, resulting in the sampling device still having safety hazards, reducing the use value of the sampling device.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] A safe sampling device for chemical wastewater detection disclosed in the present invention is mainly used in scenarios where workers take out chemical wastewater samples from inside the mechanical equipment after the chemical wastewater is sampled by mechanical equipment. Since the mechanical equipment is deeply immersed in the chemical wastewater, a small amount of chemical wastewater is attached to the outside of the mechanical equipment and in the gaps where it is connected to the outside. This part of wastewater can easily cause damage to the workers when they take out the samples, resulting in a safety hazard in the sampling device.

[0033] Reference Figure 1-Figure 10 A safe sampling device for chemical wastewater detection comprises an outer interception frame 1, the outer side wall of the outer interception frame 1 near the top is fixedly connected to two fixed blocks 13, and the tops of the two fixed blocks 13 are fixedly connected to positioning rods 8, the two positioning rods 8 are slidably connected to lifting rods 7, the bottoms of the two lifting rods 7 are fixedly connected to mounting rods 11, and the bottoms of the two mounting rods 11 are provided with safety processing components 3, the safety processing components 3 comprise an annular collection rack 301, and the annular collection rack 301 is fixedly connected to the bottoms of the two mounting rods 11, the side walls and the top of the annular collection rack 301 facing the outer interception frame 1 are provided with extraction holes 302, the tops of the two positioning rods 8 are fixedly connected to top blocks 6, and the bottoms of the two top blocks 6 are fixedly connected to electric telescopic rods 5, and the output ends of the two electric telescopic rods 5 are fixedly connected to the tops of adjacent lifting rods 7.

[0034] In a specific application scenario, after sampling the chemical wastewater, the lifting mechanism drives the outer interception frame 1 to rise above the chemical wastewater, and then starts the drive motor 1 311, the drive motor 2 316 and the adsorption pump 9. The drive motor 1 311 drives the partially filled air bag 303 to rotate, so that the bristles 305 on the outside of the air bag 303 and the wastewater attached to the outer wall and the recessed part of the outer interception frame 1 are brushed off by squeezing. At the same time, the drive motor 2 316 drives each oscillation ball 304 to impact the surface of the outer interception frame 1, so that the outer interception frame 1 is in an oscillating state, and the wastewater attached thereto gradually slides off. During the operation of the drive motor 1 311 and the drive motor 2 316, the adsorption pump 9 extracts and collects the wastewater attached to the outer interception frame 1 and the wastewater that has fallen off and been swept off through the extraction hole 302, so as to realize the treatment of the wastewater attached to the outer interception frame 1, avoid the part of the wastewater from causing harm to the staff, and improve the safety performance of the sampling device.

[0035] Specifically, before the airbag bag 303 rotates, the air pump 312 is started, and the air pump 312 introduces external gas into the airbag bag 303 through the air guide tube 314. When the airbag bag 303 is in a semi-expanded state, the filling of gas is stopped. After the flat airbag bag 303 bulges, the driving motor 311 drives it to rotate. After its two ends contact the outer wall of the outer interception frame 1, the extrusion force between the two is large, and the interaction force enables the bristles 305 to better sweep away the wastewater attached to the outer interception frame 1. When the airbag bag 303 rotates to the groove of the outer interception frame 1, the single-point groove causes the airbag bag 303 to have a local bulge that is pressed into the groove, and the bristles 305 enter the groove accordingly, thereby improving the wastewater cleaning effect inside the groove.

[0036] It should be noted that when the electric telescopic rod 5 drives the annular collection rack 301 to move to the bottom of the outer interception frame 1, the upward-facing extraction hole 302 has a certain adsorption effect on the wastewater that slides off and adheres to the outer interception frame 1, thereby accelerating the separation of the wastewater from the outer interception frame 1 and further improving the wastewater cleaning effect.

[0038] Reference Figure 1 , Figure 3 and Figure 5 In a preferred embodiment, both sides of the fixed block 13 are fixedly connected with shaft frames 315, and one side of one of the shaft frames 315 is fixedly connected with a driving motor 2 316, the output shaft of the driving motor 2 316 is fixedly connected with a rotating rod 317 through a coupling, one end of the rotating rod 317 is connected to one side of the other shaft frame 315 through a bearing, and the outer side wall of the rotating rod 317 is fixedly connected with elastic connecting rods 307 at equal distances, and the end of each elastic connecting rod 307 is fixedly connected with an oscillating ball 304.

[0039] Reference Figure 1 , Figure 3 and Figure 4In a preferred embodiment, the side wall of the annular collecting rack 301 is fixedly connected to two mounting frames 306, and the two mounting frames 306 are symmetrically distributed, the side walls of the two mounting frames 306 facing downward are fixedly connected to a driving motor 311, the output end of the driving motor 311 is fixedly connected to a rotating shaft 310, the bottom of the rotating shaft 310 is fixedly connected to an air bag 303, the bottom of the air bag 303 is provided with an exhaust hole, the inside of the exhaust hole is fixedly connected to an exhaust pipe 308, the outer wall of the exhaust pipe 308 is connected to an air valve 309 through a flange, the outer wall of the rotating shaft 310 is fixedly connected to an external ring 313, the top of the external ring 313 is fixedly connected to two air pumps 312, the air delivery ends of the two air pumps 312 are fixedly connected to an air guide pipe 314, one end of the air guide pipe 314 is inserted into the interior of the air bag 303, and the outer wall of the air bag 303 is provided with bristles 305.

[0040] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7 In a preferred embodiment, a sealing frame 2 is fixedly connected to one side of the peripheral interception frame 1, and a multi-sampling assembly 14 is provided inside the sealing frame 2 and the peripheral interception frame 1. The multi-sampling assembly 14 includes a rotating plate 1404. A driving motor 3 1405 is fixedly connected to an inner wall of one side of the sealing frame 2. The output shaft of the driving motor 3 1405 is fixedly connected to a driving shaft 1406 through a coupling. The rotating plate 1404 is fixedly connected to one end of the driving shaft 1406. The side wall of the sealing frame 2 and the peripheral interception frame 1 is fixed. It is connected to the same docking frame 12, one side of the rotating plate 1404 is fixedly connected with a fitting ring 1415, and the side wall of the outer interception frame 1 is provided with a fitting hole, the fitting hole is adapted to the fitting ring 1415, the outer side wall of the fitting ring 1415 is fixedly connected with a sampling partition 1401 at an equal distance, the sampling partition 1401 is in contact with the inner side wall of the outer interception frame 1, one side of each sampling partition 1401 is fixedly connected with a sampling arc plate 1402, and a sampling port 15 is provided on the outer side wall of the outer interception frame 1 facing downward.

[0041] In a specific application scenario, when sampling chemical wastewater, every time the lifting mechanism drives the outer interception frame 1 to descend to a height, the driving motor three 1405 drives the matching ring 1415 to rotate 60°, so that the sampling arc piece 1402 facing downward collects the chemical wastewater at that height and drives it between the two sampling partitions 1401, thereby realizing wastewater sampling at different heights. When the driving motor three 1405 drives the matching ring 1415 to rotate 360°, six groups of sampling can be completed, thereby improving the use value of the sampling device.

[0042] It should be noted that, as the wastewater sampled from the bottom rotates to the top, the wastewater between each two adjacent sampling partitions 1401 passes through the docking pipe 1407 under the action of gravity and falls into the corresponding sampling tube 1411. When the wastewater in the sampling tube 1411 reaches a certain amount, the wastewater drives the weighing plate 1412 to squeeze the weighing sensor 1413, and the electric telescopic rod 1409 drives the sealing plate 1403 to seal the pipe mouth of the sampling tube 1411, ensuring that the water inside the sampling tube 1411 will not flow back into the sampling partition 1401 as the fitting ring 1415 rotates.

[0043] Specifically, after the sampling is completed, each sampling tube 1411 is in a sealed state and the outer interception frame 1 is separated from the chemical wastewater, and the driving motor 3 1405 drives the fitting ring 1415 to rotate multiple circles, and the chemical wastewater located between each two adjacent sampling partitions 1401 is separated from the sampling port 15 under the action of gravity, thereby avoiding the residual chemical wastewater from splashing onto the staff when the staff is disassembling the sampling tube 1411 and causing injury, thereby further improving the safety performance of the sampling device.

Each clamping plate 1608 is evenly and fixedly connected with an extrusion spring rod 1606 on one side facing the inner wall of the docking tube 1603. One end of the extrusion spring rod 1606 is fixedly connected to the inner wall of the docking tube 1603. An embedded column 1604 is inserted into the interior of the docking tube 1603, and the embedded column 1604 is in contact with each clamping plate 1608. A fixing frame 1601 is fixedly connected to the outer wall of the embedded column 1604. A pulling rod 1602 is fixedly connected to the side of the fixing frame 1601 away from the docking tube 1603. A retaining ring 1605 is sleeved on the outer side of the embedded column 1604, and the retaining ring 1605 is in contact with the fixing frame 1601.

[0045] Specifically, when docking the sampling tube 1411 with the docking tube 1407, the embedded column 1604 is pressed between the clamping plates 1608. As it is pressed in, the clamping plates 1608 begin to deflect, and the extrusion spring rod 1606 is compressed. After the embedded column 1604 is pressed into the docking tube 1603, the retaining ring 1605 is pressed onto the embedded column 1604 to achieve rapid docking of the sampling tube 1411 with the docking tube 1407. When disassembling them, the staff manually pulls the pulling rod 1602 to pull the embedded column 1604 out from between the clamping plates 1608 inside the docking tube 1603, which is convenient and efficient.

[0046] Reference Figure 7 , Figure 8 and Fig. 9 In a preferred embodiment, the outer wall of the fixed frame 1601 is annularly distributed with sampling tubes 1411, and the sampling tubes 1411 are in contact with each docking tube 1407.

The bottom inner wall of the sampling tube 1411 is fixedly connected with two limit rails 1414, and the same weighing plate 1412 is slidably connected to the inside of the two limit rails 1414. The bottom inner wall of the sampling tube 1411 is fixedly connected with a weighing sensor 1413, and the weighing sensor 1413 is in contact with the weighing plate 1412.

[0047] Working principle: When in use, the lifting mechanism is docked with the docking frame 12, and then the outer interception frame 1 is driven by the lifting mechanism to gradually descend into the chemical wastewater. Whenever the lifting mechanism drives the outer interception frame 1 to descend to a height, the driving motor three 1405 drives the fitting ring 1415 to rotate 60°, so that the sampling arc piece 1402 facing downward collects the chemical wastewater at that height, and drives it between the two sampling partitions 1401, so as to realize the wastewater sampling at different heights. When the driving motor three 1405 drives the fitting ring 1415 to rotate 360°, six groups of sampling can be completed. After the six groups of sampling are completed, the lifting mechanism drives the outer interception frame 1 to move above the chemical wastewater, starts the driving motor one 311, the driving motor two 316 and the adsorption pump 9, and the driving motor one 311 drives the partially filled airbag bag 30 3 is rotated, so that the bristles 305 on the outside of the airbag bag 303 and the wastewater attached to the outer wall and the recessed part of the outer interception frame 1 are brushed off by squeezing. At the same time, the driving motor 2 316 drives each oscillation ball 304 to impact the surface of the outer interception frame 1, so that the outer interception frame 1 is in an oscillating state, and the wastewater attached thereto gradually slides off. During the operation of the driving motor 1 311 and the driving motor 2 316, the adsorption pump 9 extracts and collects the wastewater attached to the outer interception frame 1 and the wastewater that has fallen off and been swept off through the extraction hole 302, so as to treat the wastewater attached to the outer interception frame 1. After the wastewater attached to the outer interception frame 1 is cleaned, the staff manually pulls the pulling rod 1602 to pull the embedded column 1604 out from between the clamping plates 1608 inside the docking tube 1603 to complete the wastewater sampling and collection.
