Description

Technical Field

[0002] Solid adsorbent tubes are devices used to collect chemical substances (especially gaseous or vaporous substances) in the air. They are widely used in environmental monitoring and occupational health monitoring. The solid adsorbent tube mainly relies on the intermolecular forces (physical adsorption) and chemical affinity (chemical adsorption) to enrich chemical substances in the air. Physical adsorption is weak, and it is easy to desorb the adsorbed substance molecules under the influence of physical action; while chemical adsorption is strong and not easy to desorb under physical action. Impregnation of solid adsorbents is to coat chemical reagents on solid adsorbents to react chemically with the analyte to generate stable compounds, thereby increasing the adsorption capacity and improving sampling efficiency.

[0003] After sampling, the existing solid adsorbent tubes need to recover and inspect the adsorbent inside them. In order to facilitate the removal of the adsorbent, the solid adsorbent tubes need to be cut in advance.

[0041] In this embodiment, the limiting mechanism specifically includes: a receiving chamber 45 provided inside the receiving tube 44, a negative pressure chamber 46 provided below the receiving chamber 45, a through hole 47 provided between the negative pressure chamber 46 and the receiving chamber 45, an air suction hole 48 provided at the bottom end of the receiving tube 44 and connected to the negative pressure chamber 46, and the air suction hole 48 is connected to an external vacuum pumping device.

[0044] In this embodiment, the custody tube release mechanism specifically includes: four vertical slots 6 evenly opened on the inner wall of the placement hole 4, the interior of the vertical slots 6 is rotatably connected with a strip plate 7, and the top surface of the strip plate 7 is embedded with a first magnet 8, and the inner wall of one side of the vertical slots 6 is embedded with a second magnet 9, and the second magnet 9 and the first magnet 8 are magnetically repelled. The custody tube release mechanism set in the present application can not only hold the solid adsorbent tube, but also cooperate with the dumping recovery component to let the solid adsorbent tube pass when needed.

[0045] The working principle of the present invention is: when in use, first, the solid adsorbent tube to be cut is inserted into each placement hole 4 in turn, and the strip plate 7 of the tube holding mechanism supports the bottom of the solid adsorbent tube, and the elastic rubber ring 10 clamps the solid adsorbent tube, thereby fixing the solid adsorbent tube to a certain extent. Then, the automatic cutting mechanism cuts the solid adsorbent tube in a placement hole 4 in the outermost circle. The working process of the automatic cutting mechanism is as follows: the hydraulic cylinder 13 runs to extend the output shaft to drive the first box body 12 to rise to a preset height. Then, the first drive motor 16 runs to drive the first lead screw 19 to rotate, and the first telescopic arm 18 in the first telescopic slot 17 slowly extends outward along the first lead screw 19 until the sampling tube cutter 21 reaches the top of the target solid adsorbent tube. Then, the hydraulic cylinder 13 runs again to retract the output shaft, driving the sampling tube cutter 21 to descend and cover the target solid adsorbent tube. The rotary motor 20 runs to drive the sampling tube cutter 21 to rotate. The sampling tube cutter 21 cuts the solid adsorbent tube. In this process, the solid adsorbent tube is restricted by the elastic rubber ring 10 and cannot rotate with it, thereby achieving cutting. It should be noted that the model of the sampling tube cutter 21 is HYD-260.

[0046] After the first solid adsorbent tube in the outermost circle is cut, the automatic cutting mechanism returns to its initial position, and the first stepper motor 3 runs to drive the turntable 2 to rotate a preset angle, and the second solid adsorbent tube in the outermost circle arrives at the cutting station and is ready to be cut. This cycle is repeated in sequence until all the solid adsorbent tubes in the outermost circle are cut, and then the solid adsorbent tubes in the middle circle are cut, and finally the solid adsorbent tubes in the innermost circle are cut. It should be noted that when cutting solid adsorbent tubes in different circles, the extension length of the first telescopic arm 18 is preset and adjusted. In addition, each time the turntable 2 rotates, the next solid adsorbent tube will reach the position of the previous solid adsorbent tube. After the cutting of the solid adsorbent tube is completed, it reaches the position of the cutting material transfer mechanism, and the cutting material transfer mechanism transfers the cutting material for it. After the solid adsorbent tube is cut, its cutting material has not yet been separated from the tube body. The present application adopts a cutting material transfer mechanism to separate it. The specific process is: the second drive motor 25 runs to drive the second lead screw 28 to rotate, and the second telescopic arm 27 in the second telescopic slot 26 extends outward along the second lead screw 28 until the pneumatic gripper 30 completes docking with the target solid adsorbent tube. Then, the pneumatic gripper 30 runs to clamp the cutting material part of the solid adsorbent tube, and the second drive motor 25 runs in the opposite direction to drive the second telescopic arm 27 to retract. During the process, the cutting material part of the solid adsorbent tube is cut off and taken away by the pneumatic gripper 30. Subsequently, the rotating motor 29 runs to drive the second box body 23 to rotate a certain angle, so that the cutting material clamped by the pneumatic gripper 30 reaches above the first material receiving box 24. Then, the pneumatic gripper 30 runs to release the cutting material, and the cutting material falls into the first material receiving box 24.

[0047] When the solid adsorbent tube that has been cut and separated reaches the position of the dumping and recovery assembly, the dumping and recovery assembly receives the solid adsorbent tube that has been cut and dumps the solid adsorbent tube. The specific process is as follows: the linear motor 36 moves slowly along the linear guide rail 34 on the crossbeam 33. During the process, the rectangular plate 35 and the receiving tube 44 follow the movement, and then the receiving tube 44 is adjusted to the bottom of the target solid adsorbent tube. Next, the through-type stepping motor 37 operates to make the through-type stepping screw 38 rise slowly, and the lifting plate 39 and the receiving tube 44 follow the rise, and the linear bearing 40 and the linear optical axis 41 are relatively displaced to improve the lifting stability of the lifting plate 39. The rising receiving tube 44 is inserted into the placement hole 4 corresponding to the target solid adsorbent tube along the corresponding conical mouth 5. The receiving tube 44 lifts the strip plate 7 of the tube-holding mechanism and penetrates into the placement hole 4. After the strip plate 7 is lifted, it rotates into the vertical groove 6 without hindering the penetration of the receiving tube 44. Since the solid adsorbent tube is restricted in the center of the placement hole 4 by the elastic rubber ring 10, as the receiving tube 44 goes deeper, the solid adsorbent tube enters the receiving cavity 45 of the receiving tube 44. When the receiving tube 44 passes the elastic rubber ring 10, the elastic rubber ring 10 is further squeezed until the target solid adsorbent tube completely enters the receiving tube 44, and the limiting mechanism in the receiving tube 44 adsorbs and fixes the target solid adsorbent tube. Subsequently, the through-type stepping motor 37 operates to make the through-type stepping screw 38 slowly descend to the initial position, and the receiving tube 44 follows the descent and leaves the placement hole 4. The magnetic repulsion between the second magnet 9 and the first magnet 8 causes the strip plate 7 to flip out of the vertical slot 6 and return to its original state. The linear motor 36 operates to move the rectangular plate 35 to the leftmost position, and then the second stepper motor 43 operates to drive the receiving tube 44 to deflect to the lower right. During the process, the adsorbent in the target solid adsorbent tube flows out of the tube body under its own gravity and enters the guide groove 51 along the first guide plate 49, and finally falls from the guide groove 51 into the corresponding container 55 on the conveyor belt 53 below. Each time the adsorbent in a solid adsorbent tube is poured out, the conveyor belt 53 will run forward for a preset length, not only sending out the container 55 that has completed the material collection, but also sending the next empty container 55 to the lower part of the guide groove 51 to prepare for material collection. Subsequently, the linear motor 36 operates to move the rectangular plate 35 to the rightmost position, and the second stepper motor 43 operates to drive the receiving tube 44 to deflect to the lower left, so that the receiving tube 44 docks with the second guide plate 50. Next, the limiting mechanism in the receiving tube 44 releases the target solid adsorbent tube, and the target solid adsorbent tube slides out of the receiving cavity 45 and enters the chute 56 along the second material guide plate 50 , and finally falls into the second material receiving box 57 along the chute 56 .It should be noted that the specific process of the limiting mechanism to adsorb and fix the target solid adsorbent tube is that the external vacuum equipment is operated to extract the air in the negative pressure chamber 46 from the suction hole 48, and then create a negative pressure environment inside the negative pressure chamber 46. Since the negative pressure chamber 46 and the receiving chamber 45 are connected by a through hole 47, the bottom of the solid adsorbent tube entering the receiving chamber 45 is firmly adsorbed. When releasing the solid adsorbent tube, it is only necessary to stop the operation of the external vacuum equipment.
