Detailed Implementation Manner

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figures 1 - 3, an embodiment provided by the present utility model: a hydrochloric acid treatment device for laboratory environment detection, including a trolley 1, the upper surface of the trolley 1 is fixedly connected with a stirring tank 2, the top end of the stirring tank 2 is slidably connected with a top cover 3, the inside of the top cover 3 is threadedly connected with a first bolt 4, the outer wall of the first bolt 4 penetrates into the inside of the stirring tank 2, the top end of the top cover 3 is fixedly connected with a feed pipe 5, the upper surface of the top cover 3 is fixedly connected with a motor 6, the output end of the motor 6 is fixedly connected with a first rotating rod 7, the lower surface of the first rotating rod 7 is fixedly connected with a first connecting block 8, the lower surface of the first connecting block 8 is slidably connected with a second connecting block 9, the inside of the first connecting block 8 is threadedly connected with a second bolt 10, the outer wall of the second bolt 10 penetrates into the inside of the first connecting block 8, the lower surface of the second connecting block 9 is fixedly connected with a second rotating rod 11, the outer wall of the second rotating rod 11 is fixedly connected with a plurality of stirring blades 12 symmetrically arranged left and right, the upper end of the outer wall of the second rotating rod 11 is fixedly connected with a scraping plate 13, the outer wall of the second rotating rod 11 is fixedly connected with a connecting plate 14, the lower surface of the connecting plate 14 is fixedly connected with auger blades 15 symmetrically arranged left and right, and a discharge assembly is arranged at the bottom end of the stirring tank 2.

[0025] Specifically, when it is necessary to treat hydrochloric acid waste liquid, first inject the waste liquid into the inside of the stirring tank 2 through the feed pipe 5. At the same time, add an appropriate amount of sodium hydroxide solution to neutralize the acidic substances in the waste liquid. Start the motor 6, and the motor 6 drives the first rotating rod 7 and the second rotating rod 11 to rotate. The rotation of the second rotating rod 11 drives the stirring blades 12 to rotate, so as to realize the uniform stirring of the mixed solution. In addition, the rotation of the second rotating rod 11 also drives the connecting plate 14 to rotate, and the rotation of the connecting plate 14 drives the auger blades 15 to rotate. The function of the auger blades 15 is to transport the solution at the bottom of the stirring tank 2 to the inner top of the stirring tank 2, which helps to accelerate the mixing speed of hydrochloric acid and sodium hydroxide solution. During the stirring process, the rotation of the second rotating rod 11 also drives the scraping plate 13 to rotate. The function of the scraping plate 13 is to prevent the mixed solution from remaining on the inner wall of the stirring tank 2 after stirring is completed, so as to avoid corrosion of the stirring tank 2. When it is necessary to replace the stirring blades 12, first rotate the first bolt 4 to separate it from the top cover 3, and then pull the top cover 3 out of the inside of the stirring tank 2 together with the motor 6 and the stirring blades 12. Next, rotate the second bolt 10 to separate it from the first connecting block 8 and the second connecting block 9. In this way, the second rotating rod 11 and the stirring blades 12 can be disassembled and replaced.

[0026] Refer to Figure 4, the discharging assembly includes a first discharging pipe 16, the outer wall of the first discharging pipe 16 is fixedly connected inside the stirring tank 2, a solenoid valve 17 is arranged inside the first discharging pipe 16, a storage tank 18 is fixedly connected to the outer wall of the first discharging pipe 16, the lower surface of the storage tank 18 is fixedly connected to the upper surface of the trolley 1, a second discharging pipe 23 is fixedly connected to the outer wall of the storage tank 18, a solenoid valve 17 is arranged inside the second discharging pipe 23, a pH meter 19 is fixedly connected inside the storage tank 18, a delivery pump 20 is fixedly connected to the upper surface of the storage tank 18, an extraction pipe 21 is fixedly connected to the input end of the delivery pump 20, the outer wall of the extraction pipe 21 is fixedly connected inside the storage tank 18, and a reflux pipe 22 is fixedly connected to the output end of the delivery pump 20, the outer wall of the reflux pipe 22 is fixedly connected inside the stirring tank 2.

[0027] Specifically, after the treatment is completed, it is necessary to detect the solution to ensure its quality is qualified. Start the solenoid valve 17 to make the solution flow into the storage tank 18 through the first discharging pipe 16. Then, start the pH meter 19 to detect the pH value of the solution inside the storage tank 18. If the pH of the solution is unqualified, start the delivery pump 20 to pump out the solution inside the storage tank 18 through the extraction pipe 21. Then, convey the solution into the stirring tank 2 through the reflux pipe 22 for re-treatment.

[0028] Refer to Figure 5 , a purification box 24 is fixedly connected to the upper surface of the trolley 1, an exhaust fan 25 is fixedly connected to the outer wall of the purification box 24, an exhaust pipe 26 is fixedly connected to the top of the purification box 24, a connecting pipe 27 is fixedly connected to the top of the exhaust pipe 26, a plurality of dust suction pipes 28 are fixedly connected to the outer wall of the connecting pipe 27, and symmetrically arranged acidic activated carbon plates 29 are slidably connected inside the purification box 24. Sealing plates 30 are fixedly connected to the outer walls of the acidic activated carbon plates 29, and the outer walls of the sealing plates 30 are in contact with the outer wall of the purification box 24.

[0029] Specifically, when it is necessary to treat hydrochloric acid in the air, start the exhaust fan 25 to pump out the air inside the purification box 24. Since the pressure inside the purification box 24 decreases to generate suction, the air inside the connecting pipe 27 is pumped out through the exhaust pipe 26. At the same time, the air in the external environment is inhaled into the purification box 24 through the dust suction pipes 28. Inside the purification box 24, the acidic activated carbon plates 29 neutralize the hydrochloric acid. It should be noted that the acidic activated carbon plates 29 can be moved out of the purification box 24 by pulling the sealing plates 30, which is convenient for their replacement and maintenance.

[0030] Working principle: When the device needs to be used, first, the hydrochloric acid waste liquid is injected into the interior of the stirring tank 2 through the feed pipe 5, and at the same time, sodium hydroxide solution is added. Then, the motor 6 is started to drive the first rotating rod 7 and the second rotating rod 11 to rotate. The rotation of the second rotating rod 11 drives the stirring blades 12 to rotate, stirring the mixed solution. At the same time, when the second rotating rod 11 rotates, it drives the connecting plate 14 to rotate, and the rotation of the connecting plate 14 drives the auger blades 15 to rotate, transporting the solution at the bottom of the stirring tank 2 to the inner top of the stirring tank 2, accelerating the mixing of the hydrochloric acid and sodium hydroxide solutions. The rotation of the second rotating rod 11 drives the scraper 13 to rotate, preventing the mixed solution from remaining on the inner wall of the stirring tank 2 after stirring is completed, causing corrosion to the stirring tank 2. When the stirring blades 12 need to be replaced, first, rotate the first bolt 4 to separate it from the top cover 3, and pull the top cover 3 to move the motor 6 and the stirring blades 12 out of the interior of the stirring tank 2. Then, rotate the second bolt 10 to separate it from the first connecting block 8 and the second connecting block 9, disassemble the second rotating rod 11 and the stirring blades 12 and then replace them. When it is necessary to detect the processed solution, start the solenoid valve 17, and the solution flows through the first discharge pipe 16 into the interior of the storage tank 18. Start the pH meter 19 to detect the pH value of the solution inside the storage tank 18. When the pH of the solution is unqualified, start the delivery pump 20 to pump out the solution inside the storage tank 18 through the extraction pipe 21 and then transport it back to the interior of the stirring tank 2 through the reflux pipe 22 for reprocessing. When it is necessary to treat the hydrochloric acid in the air, start the exhaust fan 25 to draw away the air inside the purification box 24. The pressure inside the purification box 24 decreases to generate suction, draw away the air inside the connecting pipe 27 through the exhaust pipe 26, and then draw in the air from the external environment into the interior of the purification box 24 through the dust suction pipe 28. The hydrochloric acid is neutralized by the acidic activated carbon plate 29 inside the purification box 24. By pulling the sealing plate 30, the acidic activated carbon plate 29 can be moved out of the interior of the purification box 24, facilitating the replacement and maintenance of the acidic activated carbon plate 29.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
