[0021] 3. The sample preparation pretreatment device for chloroiridic acid detection uses a blade motor to transport water upward in the maneuvering tube. The water inside the sample water bucket flows from top to bottom, which makes the water flowing into the sampling tube evenly flow into the top and bottom layers of the sample water bucket, making the sampled water more representative, and can increase the accuracy of the detection of the amount of chloroiridic acid substances, thereby enhancing the accuracy of the detection.

[0022] 4. The sample preparation pretreatment device for chloroiridic acid detection is driven by a driving motor through a conveyor belt through a moving rotating frame to sweep the suction filter, and sweep the solid matter on the top of the suction filter to the outside of the top of the suction filter to avoid clogging of the top of the suction filter, so that the water flow inside the sample water bucket can continue to circulate downward as a whole, which can indirectly improve the detection accuracy.

DETAILED DESCRIPTION

[0033] 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.

[0034] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0035] Example 1: Please refer to Figure 1-5 The present invention provides a technical solution: a sample preparation pretreatment device for chloroiridic acid detection, comprising a sample water bucket 1, a fixed bracket 2 is fixedly connected to the outer wall of the sample water bucket 1, a sampling mechanism 3 is movably connected inside the sample water bucket 1, and a gathering mechanism 4 is fixedly connected to the bottom of the sample water bucket 1;

[0036] The sampling mechanism 3 comprises:

[0037] A sampling tube 301, the sampling tube 301 is movably connected inside the sample water bucket 1;

[0038] The rotating frame 302 is driven to be movably connected to the outer wall of the sampling tube 301, and the rotating frame 302 is driven to be movably connected to the bottom of the sample water bucket 1;

[0039] The spiral plate 303 is fixedly connected to the inside of the sampling tube 301 .

[0040] The sampled sewage is injected into the sample water bucket 1, and the sampling container is placed at the bottom of the sampling tube 301. The sewage flowing into the sampling tube 301 will flow into the container from the bottom of the sampling tube 301, and then the amount of chloroiridic acid in the container is detected, and the read value is combined with the liquid volume in the container to obtain the concentration of chloroiridic acid.

[0041] The outer wall of the sampling tube 301 is provided with a strip-shaped protrusion, and the inside of the driving rotating frame 302 is provided with a slot that cooperates with the sampling tube 301. The driving rotating frame 302 is movably connected to the sampling tube 301 through a bearing. A driving motor 304 is fixedly connected to the bottom of the sample water bucket 1, and a conveyor belt 305 is movably connected to the outer wall of the driving rotating frame 304. The conveyor belt 305 is movably connected to the outer wall of the driving rotating frame 302. When the driving rotating frame 302 rotates, the sampling tube 301 will be driven to rotate through the strip-shaped protrusion. The outer wall of the sampling tube 301 is located at the top of the driving rotating frame 302 and is fixedly connected to a water pushing plate 307.

[0042] Start the driving motor 304, and let the driving motor 304 drive the rotating frame 302 to rotate through the conveyor belt 305, and the rotating frame 302 will drive the sampling tube 301 to rotate through the strip-shaped protrusions. The rotation of the sampling tube 301 will drive the water pushing plate 307 to rotate, and the sewage inside the sample water bucket 1 will be driven to rotate. The water inside the sample water bucket 1 will cause the solid matter in the water to move around and away from the central area under the action of centrifugation. At the same time, the sampling tube 301 will rotate with the internal spiral plate 303, and the rotation of the spiral plate 303 will generate a downward airflow inside the sampling tube 301.

[0043] Three notches are arranged on the top of the sampling tube 301 , and three gas chambers 306 are fixedly connected to the outer wall of the sampling tube 301 at positions corresponding to the notches.

[0044] The air chamber 306 will allow the notch at the top of the sampling tube 301 to float at a certain position on the liquid surface, allowing the water on the top of the liquid surface to continuously flow into the sampling tube 301 through the notch, and flow out from the bottom of the sampling tube 301 to the inside of the container. At the same time, the air chamber 306 will also be driven by the sampling tube 301 to rotate, pushing the water on the top of the liquid surface to the surroundings, and pushing the solid matter in the water flowing around the top of the liquid surface to the surroundings.

[0045] The three notches provided in the sampling tube 301 are all movably connected with movable doors 309, and the movable doors 309 are rotatably connected to the sampling tube 301. The three movable doors 309 can block the notches on the sampling tube 301. The sampling tube 301 is fixedly connected with a fixed column 308, and the outer wall of the fixed column 308 is fixedly connected with three pulling springs 310, and the sampling tube 301 is respectively fixedly connected to the inner walls of the corresponding movable doors 309.

[0046] The movable door 309 is in a closed state under normal circumstances to prevent water from flowing into the sampling tube 301. When the rotation speed of the sampling tube 301 reaches a certain level, the centrifugal force exerted on the movable door 309 will overcome the pulling force of the pulling spring 310, allowing the movable door 309 to rotate around the connection with the sampling tube 301, pushing the movable door 309 outward, allowing the sewage to enter the sampling tube 301 through the gap, and the airflow generated by the spiral plate 303 pushing the air will accelerate the suction of the sewage around the gap, thereby increasing the sampling speed.

[0047] A blocking filter plate 311 is fixedly connected inside the sampling tube 301 at a position corresponding to the notch, and a pushing plate 312 is fixedly connected inside the sampling tube 301 at a top of the blocking filter plate 311 .

[0048] The blocking filter plate 311 will block the solids in the sewage from entering the sampling tube 301. When the movable door 309 is in the open state, when the blocking filter plate 311 is blocked by solid matter, the sampling tube 301 cannot pass water. At this time, the ejection plate 312 will push the solid matter and the sewage matter will be discharged from the top of the ejection plate 312 through the centrifugal effect to avoid the sampling tube 301 from being blocked.

[0049] Example 2: Please refer to Figure 1-9 Based on the first embodiment, the present invention provides a technical solution:

[0050] The gathering mechanism 4 includes a maneuvering tube 401, which is fixedly connected to the bottom of the sample water bucket 1, and there are three maneuvering tubes 401. A blade motor 403 is fixedly connected inside the maneuvering tube 401. A suction filter 402 is fixedly connected to the bottom of the sample water bucket 1 at a position corresponding to the maneuvering tube 401. The top of the maneuvering tube 401 is fixedly connected to the outer wall of the maneuvering tube 401. A blocking plate 404 is fixedly connected to the inner wall of the sample water bucket 1 at a position corresponding to the maneuvering tube 401. The blocking plate 404 will slow down the impact force of water discharge to prevent water from splashing everywhere due to excessive impact.

[0051] Simultaneously start the three blade motors 403, which will transport the water upwards, continuously sucking water from the suction filter 402 into the transfer tube 401, and discharging the water from the baffle 404, so that the water inside the sample water bucket 1 can flow from top to bottom, and the flowing water can quickly carry the solid matter downwards, thereby reducing the solid matter on the top layer of the water, and at the same time, the water flowing into the sampling tube 301 can evenly flow into the top and bottom layers of the sample water bucket 1, making the sampled water more representative.

[0052] At the same time, the continuous inflow of water into the suction filter 402 will cause the solid matter in the water to adhere to the top of the suction filter 402 under the action of the water flow, driving the rotating frame 302 to be driven by the driving motor 304 through the conveyor belt 305, which will sweep the top of the suction filter 402, and sweep the solid matter on the top of the suction filter 402 to the outside of the top of the suction filter 402 to avoid blockage of the top of the suction filter 402, so that the water flow inside the sample water bucket 1 can continue to circulate downward as a whole.

[0053] An inclined plate 405 is fixedly connected to the outer side of the rotating frame 302, and a push plate 406 is fixedly connected to the top of the inclined plate 405. A connecting groove 409 is opened on the inner wall of the sample water bucket 1 at a position corresponding to the push plate 406, and a collecting box 407 is fixedly connected to the outer wall of the sample water bucket 1 at a position corresponding to the connecting groove 409.

[0054] When the rotating rack 302 rotates, the inclined plate 405 will be rotated synchronously. The inclined plate 405 will push the solid matter brought to the edge by the water flow upward, and under the obstruction of the pushing plate 406, the solid matter will enter the collection box 407 through the connecting groove 409 under the action of centrifugal force, so as to reduce the content of solid matter inside the sample water bucket 1.

[0055] The collecting box 407 is movably connected with a partition plate 408, and a handle is provided on the top of the partition plate 408. The partition plate 408 can separate the sample bucket 1 from the collecting box 407. Pulling the handle upwards can connect the collecting box 407 with the sample bucket 1. The collecting box 407 is provided with an openable door.

[0056] When too much material accumulates inside the collection box 407, the partition plate 408 can be pushed down to separate the collection box 407 from the sample bucket 1. At this time, the door set on the collection box 407 can be opened to clean the material inside the collection box 407. After cleaning, the door on the collection box 407 is closed, and the partition plate 408 is pulled up by the handle to allow the solid material to continue to be discharged into the collection box 407.

[0057] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
