Detailed implementation manners

[0021] This part will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the protection scope of the present invention.

[0022] Please refer to Figures 1-3 , the present invention provides a technical solution: a device for quickly measuring chloroacetic acid in water quality, including a bottom plate 1. A chute 2 is opened on the upper end surface of the bottom plate 1, and a reaction tank 3 is slidably arranged inside the chute 2 through a sliding assembly.

[0023] The sliding assembly includes a slider 7. The slider 7 is slidably installed inside the chute 2.

[0024] It should be noted that a guide rail is fixedly connected to the bottom end inside the chute 2, and a sliding plate is slidably connected inside the guide rail; the bottom end of the slider 7 is fixedly connected to the sliding plate; thereby enabling the slider 7 to slide stably inside the chute 2.

[0025] Springs 8 are fixedly installed on both the left and right sides of the slider 7, and the ends of the springs 8 away from the slider 7 are fixedly connected to the inner walls of the chute 2. The top end of the slider 7 extends out of the inside of the chute 2 and is fixedly connected to the bottom end of the reaction tank 3.

[0026] A fixed plate 4 is fixedly installed on the left side of the upper end surface of the bottom plate 1, and a support plate is fixedly installed on the side of the fixed plate 4 corresponding to the reaction tank 3. A dual-shaft motor 5 is fixedly installed on the support plate. A connection assembly is provided on the bottom output shaft of the dual-shaft motor 5.

[0027] The connection assembly includes a first connecting plate 9. The first connecting plate 9 is fixedly installed on the bottom output shaft of the dual-shaft motor 5. One end of the first connecting plate 9 away from the dual-shaft motor 5 is rotatably connected to a second connecting plate 10 through a rotating shaft. One end of the second connecting plate 10 away from the first connecting plate 9 is rotatably connected to a third connecting plate 11 through the same rotating shaft. The third connecting plate 11 is fixedly connected to the outer wall of the reaction tank 3.

[0028] The connection assembly is fixedly connected to the reaction tank 3. A stirring assembly is provided on the top output shaft of the dual-shaft motor 5.

[0029] The stirring assembly includes a first rotating rod 12. The first rotating rod 12 is fixedly mounted on the top output shaft of the dual-axis motor 5. The top end of the first rotating rod 12 is rotatably mounted on the lower surface of the top plate 6. A second rotating rod 13 is rotatably mounted on the lower surface of the top plate 6 corresponding to the interior of the reaction tank 3. The bottom end of the second rotating rod 13 extends to the inner bottom side of the reaction tank 3. A plurality of stirring blades 14 are evenly fixedly mounted on the bottom side of the outer surface of the second rotating rod 13. The bottom end of the second rotating rod 13 does not contact the inner bottom surface of the reaction tank 3.

[0030] It should be noted that the movement range of the reaction tank 3 in the chute 2 is relatively small, so that the reaction tank 3 will not hit the stirring blade 14 when moving left and right, thereby not affecting the rotation of the stirring blade 14.

[0031] The first rotating rod 12 and the second rotating rod 13 are connected to each other through a transmission assembly.

[0032] The transmission assembly includes two pulleys 15. The two pulleys 15 are respectively fixedly sleeved on the top of the outer surface of the first rotating rod 12 and the second rotating rod 13. The two pulleys 15 are connected by a belt 16 transmission.

[0033] A top plate 6 is fixedly mounted on the top of the fixed plate 4. A filter assembly is arranged on the top plate 6.

[0034] The filter assembly includes a connecting pipe 17. The connecting pipe 17 is fixedly mounted on the top plate 6. The connecting pipe 17 is arranged corresponding to the interior of the reaction tank 3. The top of the connecting pipe 17 is connected to a hollow block 18; activated carbon 19 is fixedly mounted inside the hollow block 18; and the top of the hollow block 18 is connected to a filter funnel 20.

[0035] Working principle:

[0036] When in use, place the filter paper inside the filter funnel 20, then pour the water sample into the filter funnel 20, and use the filter paper to preliminarily filter out insoluble solids or precipitates; then use activated carbon 19 to absorb other trace elements and organic matter in the water sample, thereby improving the accuracy of detection, and the filtered water sample enters the interior of the reaction tank 3 through the connecting tube 17.

[0037] To ensure the accuracy of the measurement, the water sample needs to be treated for pH neutralization; a buffer solution or an acid-base solution is added to the interior of the reaction tank 3, and then the dual-axis motor 5 is started. The two output shafts of the dual-axis motor 5 rotate synchronously, and the bottom output shaft of the dual-axis motor 5 rotates to drive the first connecting plate 9 to rotate, and the first connecting plate 9 rotates to drive the second connecting plate 10 to rotate, and the second connecting plate 10 rotates to drive the third connecting plate 11 to move. Since a slider 7 is fixedly installed at the bottom end of the reaction tank 3, and the slider 7 is slidably installed inside the slide groove 2, the reaction tank 3 moves left and right driven by the third connecting plate 11.

[0038] Meanwhile, the top output shaft of the biaxial motor 5 rotates to drive the first rotating rod 12 to rotate. The rotation of the first rotating rod 12 drives the second rotating rod 13 to rotate through the pulley 15 and the belt 16. The rotation of the second rotating rod 13 drives the stirring blade 14 to rotate. Thus, while the reaction tank 3 shakes left and right, the stirring blade 14 stirs the water sample, thereby accelerating the neutralization reaction of the water sample and improving the pretreatment speed of the water sample.

[0039] The pretreated water sample can be used in an electrochemical analyzer to monitor and analyze the content of chloroacetic acid in the water quality in real time.

[0040] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the gist of the present invention.
