[0001] This invention relates to the field of drug detection technology, specifically to a purification and removal device based on drug detection. Background Technology

[0002] Contraband seized during drug raids needs to have its content detected using mass spectrometry.

[0003] For example, patent publication number CN218824064U discloses a mass spectrometry detection device for drug content, including a platform. A mass spectrometer detector is fixedly connected to the top of the platform, a movable door is movably connected to the front of the mass spectrometer detector, and a processing box is fixedly connected to the bottom of the platform. This invention, by incorporating a mass spectrometer detector and a movable door, enables rapid sample detection. By including a processing box, gas cylinder, combustion chamber, burner, flame head, and combustion rack, it can incinerate the detected samples, eliminating the need for sample storage. Furthermore, by including an exhaust pipe, chemical reaction chamber, purification chamber, connecting pipe, diversion pipe, filter cotton plate, activated carbon adsorption mesh plate, and air outlet pipe, it can treat waste gas, preventing direct air pollution. The integrated design allows for the simultaneous detection and destruction of drugs, enhancing the device's practicality.

[0004] In the aforementioned patent, by setting up a combustion treatment chamber, burner, flame head and combustion rack, the tested sample can be burned. Then the flue gas can remove harmful substances in the flue gas by passing through a chemical reaction box. However, large particulate solid impurities may remain in the flue gas entering the chemical reaction box. After these impurities enter the absorption stage, they can not only easily block the ventilation pipes and affect the flue gas flow efficiency, but also adhere to the absorbent liquid, reducing the absorbent liquid's absorption effect on acidic harmful gases, increasing the frequency of absorbent liquid replacement and increasing the treatment cost.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1 and Figure 2 The diagram illustrates a drug detection-based purification and removal device, comprising a drug combustion chamber 1, which is connected to a drug purification tower 2 via a smoke exhaust pipe. An absorption chamber 3 is installed at the bottom of the drug purification tower 2. The device also includes a filter media section 4 slidably connected to the upper part of the drug purification tower 2 for filtering the incoming smoke. A rotating shaft 5 is rotatably mounted inside the drug purification tower 2. A positioning tube 6 is fixedly sleeved on the outer side of the rotating shaft 5. A blockage-clearing section 7 is provided on the outer side of the positioning tube 6, with the lower side of the blockage-clearing section 7 located at the bottom of the absorption chamber 3. Above the filter media section 4, on the outer side of the drug purification tower 2, there is a discharge section 8, and a support ring plate 9, which is fixed inside the drug purification tower 2. A first vent pipe 10 is fixedly inserted into the support ring plate 9, and the bottom end of the first vent pipe 10 is fixedly inserted into the absorption box 3. An adjustment section 11 is provided on the first vent pipe 10, and a linkage section 12 is provided on the outer side of the positioning pipe 6. An exhaust section 13 is installed between the support ring plate 9 and the filter media section 4 for directional flow of smoke.

[0021] Among them, see Figure 10 The top of the absorption box 3 is fixed with a purification cylinder 42. Multiple packing layers 43 are evenly distributed inside the purification cylinder 42. An exhaust fan blade 44 is also fixed on the outside of the rotating shaft 5. The exhaust fan blade 44 is located inside the purification cylinder 42. Multiple second ventilation pipes 45 are fixedly inserted into the outside of the purification cylinder 42. The second ventilation pipes 45 are connected to the outside of the drug purification tower 2.

[0022] In this scheme, the sample is burned in the drug combustion chamber 1 to destroy it. The generated exhaust gas enters the drug purification tower 2 through the exhaust pipe. The gas first passes through the filter material section 4 to block large particles of impurities. Then, the external motor (not labeled in the figure) drives the rotating shaft 5 to rotate. The rotating shaft 5 drives the unblocking section 7 to rotate, thereby cleaning the impurities on the filter material section 4 and preventing blockage. At the same time, the gas treated by the filter material section 4 enters the absorption chamber 3 through the first vent pipe 10 to absorb the flue gas and react and neutralize the harmful substances in the exhaust gas. The gas generated after reacting with the solution in the absorption chamber 3 is drawn into the purification cylinder 42 by the rotation of the exhaust fan blade 44. The multiple packing layers 43 in the purification cylinder 42 will purify the gas again and absorb the harmful gases again, finally ensuring that the discharged gas meets the emission standards.

[0023] For further details, please refer to [link / reference]. Figure 2 and Figure 3 The filter media section 4 includes a baffle plate 14 with filter holes evenly distributed on it. A first sliding rod 15 is fixed to the bottom of the baffle plate 14. A first limiting ring plate 16 is fixed to the inner side of the drug purification tower 2. The first sliding rod 15 is slidably sleeved with the first limiting ring plate 16. The middle part of the baffle plate 14 is sleeved with the positioning tube 6. A sliding plate 17 is fixed at the position where the outer side of the baffle plate 14 contacts the drug purification tower 2. The sliding plate 17 is slidably connected to the inner wall of the drug purification tower 2. The sliding plate 17 matches one end of the discharge section 8.

[0024] Among them, see Figure 1 and Figure 6 The discharge section 8 includes a fixed frame 18, which is fixedly inserted through the inside and outside of the drug purification tower 2. The sliding plate 17 is adapted to the end of the fixed frame 18 facing the inside of the drug purification tower 2. A discharge channel 19 is fixedly inserted into the bottom of the fixed frame 18, and a guide component 20 is installed on the top of the fixed frame 18.

[0025] Specifically, the gas introduced into the drug purification tower 2 is blocked by the filter holes on the baffle plate 14, preventing large particles of impurities from entering the absorption box 3 along with the airflow. At the same time, the baffle plate 14 moves up and down, cooperating with the sliding plate 17 to open and close one end of the fixed frame 18. When the baffle plate 14 moves down, the sliding plate 17 and the fixed frame 18 separate, and the fixed frame 18 opens. At this time, the unblocking part 7 pushes the impurities on the baffle plate 14 into the fixed frame 18 and discharges them to the bottom of the drug purification tower 2 through the discharge channel 19, making it convenient for personnel to clean.

[0026] It should be noted that, for reference Figure 1 , Figure 2 and Figure 11 The exhaust section 13 includes a first conical hood 46 fixedly connected to the bottom of the baffle plate 14. The bottom of the first conical hood 46 is connected to a corrugated pipe 47. An axial flow fan 48 is installed on the inner side of the rigid pipe at the bottom of the corrugated pipe 47. The bottom of the corrugated pipe 47 is connected to a second conical hood 49. The bottom of the second conical hood 49 is fixedly connected to the support ring plate 9. The filtered flue gas can enter the corrugated pipe 47 through the first conical hood 46 under the action of the axial flow fan 48, and then enter the absorption box 3 through the second conical hood 49 and the first vent pipe 10. This ensures that the gas does not overflow after the fixed frame 18 is opened. The corrugated pipe 47 can adaptively expand and contract with the rise and fall of the baffle plate 14 to ensure the sealing of the flue gas transportation and avoid the flue gas leakage from affecting the filtration and purification effect.

[0027] For further details, please refer to [link / reference]. Figure 3 - Figure 5 The unblocking part 7 includes an arc-shaped push rod 21. A slider 22 is fixed to one end of the arc-shaped push rod. A groove adapted to the slider 22 is opened on the outer side of the positioning tube 6. The bottom side of the arc-shaped push rod 21 is slidably connected to the baffle plate 14. A transmission sleeve 23 is fixedly sleeved on the outer side of the positioning tube 6. A reciprocating thread groove 24 is provided on the outer side of the transmission sleeve 23. A lifting block 25 is slidably connected in the reciprocating thread groove 24. A first L-shaped plate 26 is fixed on one side of the lifting block 25. The top of the first L-shaped plate 26 is fixed to the bottom of the baffle plate 14. The top of the linkage part 12 is fixedly connected to the first L-shaped plate 26.

[0028] Specifically, when the rotating shaft 5 rotates, it also drives the arc-shaped push rod 21 to rotate. The rotation of the arc-shaped push rod 21 on the baffle plate 14 pushes large particles of impurities, preventing the filter holes from being blocked. In addition, the rotating shaft 5 also drives the transmission sleeve 23 to rotate. The reciprocating threaded groove 24 on the outer side of the transmission sleeve 23 drives the lifting block 25 to move up and down reciprocally, which in turn drives the baffle plate 14 to move up and down reciprocally. This makes it easier for the sliding plate 17 and the fixed frame 18 to remain open, allowing large particles of impurities to smoothly enter the fixed frame 18 for collection.

[0029] For further details, please refer to Figure 10 A synchronous shaft 40 is fixed to the bottom end of the rotating shaft 5. The synchronous shaft 40 passes through the top of the absorption box 3. Multiple stirring paddles 41 are evenly fixed to the outer bottom of the synchronous shaft 40. The stirring paddles 41 are located inside the absorption box 3. The rotating shaft 5 drives the synchronous shaft 40 to rotate together. The synchronous shaft 40 drives the stirring paddles 41 to rotate, so that the stirring paddles 41 agitate the solution in the absorption box 3, accelerate the reaction efficiency between harmful substances and absorption liquid, and improve the purification effect of flue gas.

[0030] Example 2: Please refer to Figure 7 , Figure 8 and Figure 11 This embodiment further explains Example 1, the difference being that the gas introduction structure inside the absorption box 3 is optimized.

[0031] Specifically, the linkage part 12 includes a second limiting ring plate 27, a second L-shaped plate 28 is fixed to the top of the second limiting ring plate 27, the top of the second L-shaped plate 28 is fixedly connected to the first L-shaped plate 26, a plurality of rotating rods 29 are hinged to the bottom of the second limiting ring plate 27, an adjusting part 11 is hinged to the bottom of the rotating rods 29, and a plurality of second sliding rods 30 are slidably sleeved on the second limiting ring plate 27, the bottom end of the second sliding rods 30 is fixed to the support ring plate 9; Meanwhile, the adjustment part 11 includes a third L-shaped plate 31 hinged to the bottom of the rotating rod 29. The bottom of the third L-shaped plate 31 is slidably connected to the support ring plate 9. A through groove 32 is provided on the third L-shaped plate 31. The second rack is fixed to the outside of the third L-shaped plate 31. A horizontal shaft 33 is rotatably connected to the third L-shaped plate 31. A guide plate 34 is fixed to the outside of the horizontal shaft 33. The third L-shaped plate 31 is slidably connected to the first vent pipe 10.

[0032] Specifically, when the baffle plate 14 moves up and down, it drives the first L-shaped plate 26 to move together, which in turn drives the second limiting ring plate 27 to move up and down through the second L-shaped plate 28. The second limiting ring plate 27 drives multiple rotating rods 29 to move, and the rotating rods 29 push the third L-shaped plate 31 to slide along the support ring plate 9. The multiple third L-shaped plates 31 move towards the center of the first vent pipe 10 at the same time, which in turn causes the third L-shaped plates 31 to push the horizontal shaft 33 and the guide plate 34 to rotate, causing the multiple guide plates 34 to converge towards the center, increasing the opening of the air intake channel of the first vent pipe 10; while when the baffle plate 14 moves upward... At this time, multiple third L-shaped plates 31 slide in opposite directions, and the guide plate 34 reopens and reduces the opening of the air intake channel, thereby realizing the adaptive adjustment of the air intake volume of the first vent pipe 10: when the baffle plate 14 moves down to open the discharge channel 19 to discharge impurities, the air intake volume of the first vent pipe 10 automatically reduces the gas leakage caused by the opening of the fixed frame 18 at this time, ensuring the stability of the internal air pressure of the device during the discharge process, and avoiding the overflow of unpurified flue gas to affect the purification effect; when the baffle plate 14 moves up to close the fixed frame 18, the air intake volume automatically expands, ensuring the normal purification efficiency of the flue gas, without the need for additional power control, and with a higher degree of automation.

[0033] Example 3: Please refer to Figure 6 and Figure 9 This embodiment further illustrates other embodiments, with the difference being the optimization of the structure of the fixed frame 18.

[0034] Specifically, the guide component 20 includes a servo motor 35, which is fixed to the top of the fixed frame 18. A drive wheel 36 is fixed to the output end of the servo motor 35. The drive wheel 36 is connected to a driven wheel 37 via a synchronous belt. A transmission rod 38 is fixedly sleeved in the central hole of the driven wheel 37. The transmission rod 38 is rotatably connected to the fixed frame 18. Multiple guide plates 39 are fixedly connected to the outside of the transmission rod 38. The multiple guide plates 39 are evenly distributed inside the fixed frame 18.

[0035] It should be noted that the driving pulley 36 and the driven pulley 37 are pulleys or gears. The synchronous belt can also be replaced with a belt or a toothed belt according to actual usage requirements. Those skilled in the art can choose flexibly according to the actual installation space, and no additional restrictions are made here.

[0036] Specifically, the servo motor 35 drives the drive wheel 36 to rotate, and the drive wheel 36 drives the driven wheel 37 to rotate via a synchronous belt. The driven wheel 37 drives the rotating rod 29 and the guide plate 39 to rotate. The rotating guide plate 39 continuously pushes the impurities that enter the fixed frame 18 to the discharge channel 19, avoiding the accumulation and jamming of impurities in the fixed frame 18, ensuring the smooth discharge of impurities, and further reducing the frequency of manual cleaning.

[0037] In this plan, the procedure for destroying drugs after testing is as follows: First, the drug samples to be destroyed are placed into the drug combustion chamber 1 after testing. The device is started to burn and destroy the drug samples. The generated smoke is transported to the drug purification tower 2 through the exhaust pipe. The smoke entering the drug purification tower 2 first passes through the baffle plate 14 of the filter material section 4. The filter holes on the baffle plate 14 intercept and filter large solid impurities in the smoke to prevent large impurities from entering the subsequent stages and clogging the pipeline or contaminating the absorption liquid. After filtration, the large impurities remain on the surface of the baffle plate 14. The filtered smoke enters the exhaust section 13 and is guided by the axial flow fan 48 to be transported sequentially through the first conical hood 46, the corrugated pipe 47, and the second conical hood 49 to the first ventilation pipe 10. Finally, it is introduced into the absorption liquid in the absorption chamber 3 to neutralize and absorb the toxic and harmful substances in the smoke. Then, the external power component drives the rotating shaft 5 to rotate continuously. The rotating shaft 5 drives the positioning tube 6 and the transmission sleeve 23 to rotate synchronously. The reciprocating thread groove 24 on the outside of the transmission sleeve 23 drives the lifting block 25 to reciprocate in the vertical direction, which in turn drives the first L-shaped plate 26 and the baffle plate 14 to reciprocate in the vertical direction. At the same time, the rotating shaft 5 drives the arc-shaped push rod 21 to rotate synchronously with the positioning tube 6. The rotating arc-shaped push rod 21 continuously scrapes the surface of the baffle plate 14, pushing the large particles of impurities intercepted on the surface of the baffle plate 14 to the outside. When the baffle plate 14 moves down to the point where the sliding plate 17 is misaligned with the fixed frame 18, the fixed frame 18 is connected, and the impurities pushed by the arc-shaped push rod 21 smoothly enter the fixed frame 18. Then, the impurities are pushed to the discharge channel 19 through the guide plate 39 of the guide component 20 and discharged outside the device, completing the automatic cleaning of filtered impurities. The cleaning process does not require stopping the machine, ensuring that the device can operate continuously. Finally, after the flue gas enters the absorption box 3, it reacts with the absorbent liquid inside the absorption box 3. During the rotation of the rotating shaft 5, the synchronous shaft 40 at the bottom and the stirring paddle 41 are rotated simultaneously. The stirring paddle 41 stirs the absorbent liquid, accelerating the reaction rate between the toxic and harmful substances and the absorbent liquid. The gas after preliminary absorption floats to the top of the absorption box 3 and then enters the purification cylinder 42. The rotating shaft 5 drives the exhaust fan blade 44 inside the purification cylinder 42 to rotate. Under the suction action of the exhaust fan blade 44, the gas passes through the multiple layers of packing 43 inside the purification cylinder 42 in sequence. The packing layer 43 performs secondary purification and adsorption on the gas, further removing the residual toxic and harmful substances in the gas. Finally, the purified gas that meets the standards is discharged to the outside of the device through the second vent pipe 45, completing the purification treatment of the drug destruction flue gas.
