Description

Technical Field

[0001] The utility model relates to the technical field of air detection, and in particular to an air collecting device for air detection. Background Art

[0002] As a key link in safeguarding public health, environmental protection, public safety and scientific research, the importance of air testing is self-evident. Through accurate air testing, we can monitor the concentrations of various pollutants in the atmosphere in real time, assess air quality conditions, and provide basic data for formulating environmental protection policies, warning of health risks and promoting scientific research.

[0003] In air testing, air pressure is an important factor affecting the accuracy of test results. Traditional detection methods often rely on suction equipment to collect air samples for analysis. However, since the air pressure of directly collected air is generally low, this may not be sufficient to meet the needs of certain detection instruments. At the same time, higher air pressure can improve the transmission efficiency and detection limit of samples, thereby ensuring the accuracy and reliability of the data. In addition, dust and other pollutants retained in the air, such as particulate matter and volatile organic compounds, will interfere with the test results and may cause blockage of the sampling equipment, thereby reducing the sampling efficiency and even generating false positive signals during the detection process. Especially in areas with poor air quality, high concentrations of pollutants in the air will seriously affect the performance of the detection equipment and the accuracy of the data.

[0004] Therefore, in order to solve the above problems, it is urgent to propose an air collection device for air detection that can filter air impurities. Utility Model Content

DETAILED DESCRIPTION

[0020] The above scheme is further described below with reference to specific examples. It should be understood that these examples are intended to illustrate the present application and are not intended to limit the scope of the present application. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer. The implementation conditions not specified are generally those used in routine experiments.

[0021] Example: An air collection device for air detection, such as Figure 1-Figure 5As shown, it includes a mounting frame 1, an air suction pump 2, an air intake pipe 3, a pressurizing pipe 4, a double-headed manifold 5, a storage tank 6, an electric push rod 7, an extrusion frame 8, a gripping pipe 9, a limiting sleeve 10, a fixing frame 11 and a filter frame 12. The top of the mounting frame 1 is provided with an air suction pump 2, which is responsible for drawing air from the outside. The air intake port at the front of the air suction pump 2 is connected to the air intake pipe 3. Pressurizing pipes 4 are provided on both sides of the mounting frame 1. During use, a pressure gauge can be provided on the pressurizing pipe 4 as needed to observe the pressure change data during subsequent operation to ensure accurate operation. Accuracy, the two pressurized pipes 4 are respectively connected to the exhaust port on one side of the suction pump 2, the suction port of the suction pump 2 is connected to the outside through the air inlet pipe 3, and at the same time, there is a pressurized pipe 4 on each side connected to the exhaust port on one side of the suction pump 2, which is used to receive and preliminarily pressurize the air. A storage tank 6 is slidingly provided at the middle raised position on the top of the mounting frame 1, which can slide forward and backward along this position, thereby facilitating the loading and unloading and adjustment of the storage tank 6. The rear end thread of the storage tank 6 is provided with a double-headed manifold 5, and the two are in a detachable state. The two joints of the double-headed manifold 5 are respectively connected to the pressurized pipe 4 on the same side The air in the pressurized pipe 4 is connected to each other, and the air in the pressurized pipe 4 is transported to the storage tank 6 through two interfaces to realize the confluence of air. An electric push rod 7 is installed on the top front side of the mounting frame 1. The telescopic end of the electric push rod 7 is connected to an extrusion frame 8. The two ends of the extrusion frame 8 are respectively embedded in the interior of the pressurized pipe 4 on the same side, and slide with the pressurized pipe 4 on the same side. Through the telescopic action of the electric push rod 7, the extrusion frame 8 can move inside the pressurized pipe 4 to realize the physical compression of the air, thereby achieving the air pressurization operation. A gripping tube 9 is provided at the front end of the air inlet pipe 3 to facilitate the gripping operation of the staff. A limiting sleeve 10 is provided at the top of the holding tube 9, and snap-in holes are provided on the left and right sides of the top of the limiting sleeve 10, and snap-in blocks adapted to the snap-in holes are presented on both sides of the fixing frame 11, thereby realizing snap-in connection between the fixing frame 11 and the limiting sleeve 10, so as to facilitate subsequent disassembly and installation. The limiting sleeve 10 is snap-fitted to the fixing frame 11, so that the fixing frame 11 enters the interior of the holding tube 9, and two filter frames 12 are provided between the inner walls of the fixing frame 11. The entry of the fixing frame 11 can assist in the placement of the two filter frames 12, so that the filter frames 12 can filter the air inside the holding tube 9.

[0022] like Figure 5As shown, it also includes a guide sleeve 13, a slide rod 14, an elastic member 15 and a rotating plate 16. Guide sleeves 13 are provided on both sides of the middle protrusion on the top of the mounting frame 1. A slide rod 14 is slidably provided in the middle position of the guide sleeve 13. The slide rod 14 slides in the front and rear directions. An elastic member 15 is provided between the slide rod 14 and the guide sleeve 13 on the same side. In this embodiment, the elastic member 15 is a spring, and the front ends of the two slide rods 14 are rotatably provided with a rotating plate 16. The two rotating plates 16 are arranged in opposite directions, and the upper side edges of the two rotating plates 16 close to each other are right-angled. The design of the right-angled edges ensures stable contact of the rotating plates 16. On the contrary, the lower side edges of the two rotating plates 16 close to each other are rounded, which can facilitate the two rotating plates 16 to be opened by sliding upward.

[0023] like Figure 1 As shown, a handle 17 is also included. Two handles 17 are provided at the middle raised position on the top of the mounting frame 1, which can facilitate the carrying and movement of the entire device.

[0024] like Figure 1 As shown, a bottom plate 18 is also included. The bottom of the mounting frame 1 is provided with the bottom plate 18. The bottom plate 18 can increase the height difference between the mounting frame 1 and the ground to facilitate the use of the device.

[0025] like Figure 3 As shown, a C-shaped frame 19 is also included. The C-shaped frame 19 is set on the right side of the mounting frame 1. The C-shaped frame 19 is clamped with the gripping tube 9 to facilitate the placement and removal of the gripping tube 9.

[0026] When it is necessary to test the air, the staff first places the device on the horizontal surface, and then holds the holding tube 9, aligns its opening with the position where air needs to be extracted, and then starts the suction pump 2. The suction pump 2 sucks the air, and the air first flows through the filter frame 12 to filter the impurities in the air, and then flows through the holding tube 9 through the intake pipe 3, and is finally transported by the suction pump 2 to the pressurized pipes 4 on both sides. At this time, the two pressurized pipes 4 are filled with air, but because the air is in a low-pressure state, it is not conducive to the accuracy of the test. The staff then starts the electric push rod 7, and the electric push rod 7 drives the extrusion frame 8 to move backward, that is, the two ends of the extrusion frame 8 compress the internal air of the two pressurized pipes 4 respectively, and observes the changes in the pressure gauge data simultaneously. When the pressure gauge reaches a certain value, in order to achieve physical pressurization of the air, the air is squeezed and pushed into the double-headed manifold 5, and then gathered in the storage tank 6, that is, the air pressurization operation is completed, and the air is collected. When the storage tank 6 stops moving, the two rotating plates 16 can be rotated upward to open the two rotating plates 16, take out the storage tank 6, and start the subsequent detection of the internal air.
