Description

Technical Field

[0001] The utility model relates to the technical field of oil fume samplers, and more particularly to an oil fume sampler for restaurant oil fume waste gas. Background Art

[0002] Cooking fumes, a common pollutant generated during the cooking process, are a complex mixture of pollutants. Common components include acrolein, volatile nitrosamines, crotonaldehyde, and compressed acetone. Therefore, to effectively manage cooking fume pollution, it is necessary to sample the exhaust gas from the exhaust outlet and conduct qualitative and quantitative analysis to develop a sound treatment plan.

[0003] Since the oil fume ducts are installed at a higher position, the existing oil fume sampler for catering oil fume waste gas requires the staff to manually lift the sampling gun to the port position of the oil fume duct in the catering kitchen, and sample the oil fume discharged from the oil fume duct through the sampling gun. The oil fume sampled by the sampling gun is then transported to the inside of the sampling box through the connecting pipe and detected by the oil fume detection equipment inside the sampling box. In order to ensure the accuracy of oil fume detection, oil fume sampling needs to be carried out for a long time and multiple times. The staff holds the sampling gun for a long time, which makes the staff feel tired, increases the staff's workload, and affects the staff's other work. In addition, the staff shakes while holding the sampling gun, which makes it inconvenient to stably adjust the sampling gun to the corresponding height for sampling, affecting the accuracy of sampling detection and reducing its practicality.

[0031] In this embodiment, the two splints 8 are put on both sides of the oil fume duct, and the top of the base 3 is in contact with the bottom of the oil fume duct, and then the gear 10 is rotated. The rotation of the gear 10 causes the two racks 5 to move toward the middle, and the two racks 5 drive the two splints 8 to move toward the middle, so that the two splints 8 clamp the oil fume duct, thereby facilitating the fixing of the sampling gun 2 on the oil fume duct. In the process of sampling oil fume, people are prevented from feeling tired from holding the sampling gun 2 for a long time, the work intensity of the staff is reduced, manpower is saved, and it is convenient for the staff to do other work.

By pressing tightly, the rotating shaft 17 and the gear 10 are rotated conveniently through the first adjusting tube 22 and the connecting column 19. By pushing the gear 10 upward, a part of the gear 10 is pushed into the inside of the circular groove 25, so that the clamping column 27 is separated from the clamping groove 26, which facilitates the rotation of the gear 10. By pulling the gear 10 and the clamping column 27 downward and inserting the clamping column 27 into the corresponding clamping groove 26, the gear 10 is fixed, the gear 10 is prevented from rotating, the rack 5 is prevented from sliding, and its stability fixed on the oil fume duct is improved.

[0034] See also Figure 6 The adjustment mechanism includes a screw tube 28, which is rotatably connected to the connecting plate 11. A screw 29 is threadedly connected to the screw tube 28.

[0036] In summary, when the overall equipment is in use:

[0037] First, move the sampling box 1 to a suitable position, then lock the universal wheel 35, and then insert the block 18 into the inside of the square groove 20, and then tighten the first screw 21 so that the side end of the first screw 21 is pressed against the side end of the block 18, so as to facilitate connecting the connecting column 19 to the rotating shaft 17, and adjust the total length of the first adjusting tube 22 and the connecting column 19 by sliding the first adjusting tube 22 on the outside of the connecting column 19. Adjust the first adjusting tube 22 and the connecting column 19 to a suitable length according to the height of the oil fume duct, and then tighten the second screw. The second adjusting tube 31 is slid outside the screw 28 to adjust the length of the second adjusting tube 31 and the screw 28, and then the third screw 32 is tightened to make the side end of the third screw 32 and the outer wall of the screw 28 close to fix the second adjusting tube 31. Then the base 3 is lifted by the first adjusting tube 22 and the connecting column 19, and the two splints 8 are put on both sides of the oil fume duct, and the top of the base 3 is in contact with the bottom end of the oil fume duct. The sampling gun 2 is located at the port of the oil fume duct, and the first regulating tube 22, the connecting column 19, the rotating shaft 17 and the gear 10 are pushed upward to separate the clamping column 27 from the clamping groove 26. When the top of the gear 10 contacts the top of the circular groove 25, the gears 10 and the gears 10 are still in a meshing state. At the same time, the first regulating tube 22, the connecting column 19, the block 18, the rotating shaft 17 and the gear 10 are rotated. The gear 10 rotates to move the two racks 5 toward the inside of the cavity 4, and the two racks 5 drive the two splints 8 to the middle. Move and make the two splints 8 clamp and fix the oil fume duct, thereby fixing the base 3 on the oil fume duct, and then by rotating the second adjusting tube 31 and the screw tube 28, the screw 29 moves up and down relative to the screw tube 28, and the screw 29 drives the fixed block 30, the convex strip 13, the fixed column 14, the fixed tube 15 and the sampling gun 2 to move up and down, and adjust the sampling gun 2 to a suitable height.
