Description

Technical Field

[0001] The present invention relates to the technical field of collection and detection devices, and particularly to a collection and detection device for aerosol after reaction. Background Technique

[0002] An aerosol is a colloidal dispersion system formed by the dispersion and suspension of solid or liquid small particles in a gas medium, also known as a gas dispersion system. Its dispersed phase is solid or liquid small particles with a size of 0.001 - 100 microns, and the dispersion medium is a gas.

[0003] Specific examples of aerosols include clouds, fog, dust in the sky, smoke formed by unburned fuel in boilers and various engines used in industry and transportation, solid dust formed during mining, quarrying abrasive materials, and grain processing, and artificial screening smoke screens, etc.

[0004] There are many aerosol precipitants on the market that achieve the elimination of aerosols by precipitating particles. After these aerosol precipitants are produced, it is necessary to detect their efficiency and efficacy. However, it is relatively difficult to detect the efficiency and efficacy of aerosol precipitants in a large environment and it is not convenient to operate. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is reasonably arranged and has strong functionality, and has the following advantages:

[0018] 1. The base box and the movable box sleeve provided can form a closed space. The aerosol is introduced into the closed space, and then the aerosol precipitant is added in the closed space to make the two react, so that it is more convenient to observe the efficiency and efficacy of the aerosol precipitant, making the detection experiment more convenient to carry out. Moreover, the movable box sleeve and the base box are movably arranged. When not in use, the movable box sleeve is in a storage state, making the volume of the whole device smaller and convenient for transportation and storage. When in use, the movable box sleeve is pulled upwards to ensure the closed experimental space.

[0019] 2. When the movable box sleeve moves upwards, it will drive the rotary disk body to move. As the rotary disk body moves, it will push the annular fixing plate downwards until the locking insertion column is aligned with the locking insertion hole, and then the annular fixing plate moves upwards to fix the rotary disk body and thus fix the movable box sleeve, ensuring the stability of the closed space. Moreover, when the movable box sleeve moves upwards, it will drive the two pushing and concentrating plates to move away from each other and contact the inner walls at both ends of the base box. The rotation of the rotary disk body will also drive the closing movable plates to move towards each other and close together to close the falling through hole, ensuring the sealing performance during the experiment.

[0020] 3. Additionally, after the detection experiment is completed, push the annular fixing plate downward so that the locking plug post withdraws from the locking jack. In this way, the movable box sleeve can be in an active state and slowly move downward to reset it, driving the pushing and concentrating plate to move toward each other. Under the action of the pushing and concentrating plate, the sediment on the bottom surface of the base box can be pushed and concentrated to the falling through-hole. At the same time, as the rotating disk body rotates in the reverse direction, it will also drive the closing movable plate to move in the reverse direction and separate. In this way, the sediment can fall onto the receiving tray and be discharged. At the same time, under the action of the feeding inclined surface, the sediment accumulated on the closing movable plate can be pushed down. Description of the Drawings

[0042] There are two closed movable plates 7, which are respectively inserted into two storage insertion cavities 182. The rotary disk bodies 6 at the same end of the base box 1 are connected to the closed movable plates 7 below them. Sealing sliding strips 71 are symmetrically and fixedly arranged at both ends of the closed movable plate 7. The sealing sliding strips 71 are inserted into the sealing sliding channels 181. A bearing insertion block 72 is fixedly arranged on the closed movable plate 7. The bearing insertion block 72 is inserted into the moving channel 183. A connecting carrier plate 721 is fixedly arranged at the lower end of the bearing insertion block 72.

A sealing insertion slot 77 is formed on the other closed movable plate 7. In addition, when the closed movable plates 7 are closed together, they play a role in closing the falling through hole 18. At this time, the sealing insertion strip 75 is inserted into the sealing insertion slot 77. The arrangement of the cylindrical surface 76 is to prevent precipitation from accumulating on the sealing insertion strip 75.

[0043] The annular fixing plate 8 is sleeved on the base box 1. Matching channels 81 are symmetrically formed on both sides of the annular fixing plate 8. Driving arc-shaped rods 66 are inserted into the matching channels 81. Support carrier rods 82 are respectively fixedly arranged at the four corners of the lower side of the annular fixing plate 8. A matching plug plate 83 is fixedly arranged at the lower end of the support carrier rod 82. The matching plug plate 83 is inserted into the movable matching cavity 153.

[0045] When no experiment is being conducted, the movable box sleeve 2 is in a stored state, making the volume of the entire device smaller and facilitating the transportation and storage of the device. When conducting a detection experiment, pull the movable box sleeve 2 upward to increase the internal space. As the movable box sleeve 2 moves upward, under the action of the connecting plug post 52, it will drive the rotating disk body 6 to rotate, causing the locking plug post 63 to rotate downward, and at the same time, the connecting bearing plate 64 to rotate upward. As the locking plug post 63 rotates, it will come into contact with the annular fixed plate 8. In this way, under the action of the locking plug post 63, the annular fixed plate 8 will be pushed downward. As the annular fixed plate 8 moves downward, under the cooperation of the plug plate 83, the gas in the movable fitting cavity 153 will be compressed until the locking plug post 63 aligns with the locking jack 831. Under the action of the compressed gas, the annular fixed plate 8 will move upward and reset, thereby enabling the locking plug post 63 to be inserted into the locking jack 831, realizing the fixation of the annular fixed plate 8, and further realizing the fixation of the movable box sleeve 2. When the movable box sleeve 2 moves upward, under the action of the driving hinge rod 29, it will drive the two pushing and concentrating plates 3 to move away from each other and come into contact with the inner walls at both ends of the base box 1. At the same time, as the rotating disk body 6 rotates, it will also drive the two closing movable plates 7 to move toward each other and close together to close the falling through hole 18. At this time, the closed space is formed. Connect the aerosol delivery pipe 25 to the aerosol reaction device to realize the delivery of the aerosol. After the delivery is completed, the aerosol precipitant can be delivered through the precipitant delivery pipe 22 to cause the two to react, generating precipitation to detect the efficiency and efficacy of the aerosol precipitant. After the experiment is completed, press the annular fixed plate 8 downward to make the locking plug post 63 withdraw from the locking jack 831, so that the movable box sleeve 2 is in an active state. Then slowly move the movable box sleeve 2 downward to reset it. It will drive the pushing and concentrating plates 3 to move toward each other to push the precipitate, making the precipitate concentrate at the falling through hole 18. At the same time, as the rotating disk body 6 flips and resets, it will also drive the closing movable plates 7 to move away from each other and separate, making the falling through hole 18 in an open state. In this way, the precipitate can be discharged and fall into the receiving tray 9 for collection. The arranged pushing inclined surface 1821 contacts the upper end surface of the closing movable plate 7, which can prevent the precipitate from accumulating on the closing movable plate 7.
