[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0031] Reference Figs. 1 to 3 A waste gas and wastewater detection device with sampling function, comprising:
[0032] The sampling cylinder 1 and the handle 2 fixedly installed on the surface of the sampling cylinder 1 are provided with a rubber sleeve 21, which improves the comfort and stability of the user when holding the handle 2.
[0033] The exhaust gas sampling chamber 3 and the wastewater sampling chamber 4 are symmetrically arranged inside the sampling cylinder 1; the exhaust gas sampling pipe 5 and the wastewater sampling pipe 6 are respectively connected to the two ends of the sampling cylinder 1 and are respectively connected to the exhaust gas sampling chamber 3 and the wastewater sampling chamber 4; the exhaust gas delivery pipe 7 and the wastewater delivery pipe 8 are fixedly connected to the outer surface of the sampling cylinder 1 and are respectively connected to the exhaust gas sampling chamber 3 and the wastewater sampling chamber 4; the other end of the exhaust gas delivery pipe 7 and the wastewater delivery pipe 8 are connected to the body of the external exhaust gas and wastewater detection device. The body of the exhaust gas and wastewater detection device is not shown in this technical solution, which is the existing publicly available technology.
[0034] Multiple one-way valves 9 are installed on the waste gas sampling pipe 5, the waste gas delivery pipe 7, and the wastewater delivery pipe 8, respectively. The multiple one-way valves 9 can ensure that the waste gas can only flow along the route of waste gas sampling pipe 5 - waste gas sampling chamber 3 - waste gas delivery pipe 7, and at the same time, the wastewater can only be discharged from the wastewater sampling chamber 4 through the wastewater delivery pipe 8, and neither can flow in reverse.
[0035] Two sampling components are installed in the exhaust gas sampling chamber 3 and the wastewater sampling chamber 4, respectively. Each sampling component includes a piston 16 slidably connected inside the sampling tube 1. A right-angle rod 17 is fixedly installed at one end of the piston 16, and the other end of the right-angle rod 17 slides through to the outside of the sampling tube 1 and is fixedly installed with a handle 19. Rubber pads 20 are fixedly installed on opposite sides of the two handles 19. The two pistons 16 are slidably fitted into the exhaust gas sampling chamber 3 and the wastewater sampling chamber 4, respectively. When sampling exhaust gas or wastewater, the user first holds the handle 2, then inserts the exhaust gas sampling tube 5 or the wastewater sampling tube 6 into the exhaust gas or wastewater, and then pulls the corresponding handle 19, which pulls the right-angle rod 17. The piston 16 slides within the exhaust gas sampling chamber 3 or wastewater sampling chamber 4, compressing the corresponding second spring 18. This allows exhaust gas or wastewater to be drawn into the exhaust gas sampling chamber 3 or wastewater sampling chamber 4 via the exhaust gas sampling tube 5 or wastewater sampling tube 6. Finally, the handle 19 is released, and under the elastic force of the second spring 18, the piston 16 moves in the opposite direction, discharging the exhaust gas or wastewater into the exhaust gas delivery pipe 7 or wastewater delivery pipe 8, until it is sent to the external exhaust gas and wastewater monitoring device for testing. This allows for the use of different sampling tubes and chambers to sample exhaust gas and wastewater, avoiding cross-contamination and ensuring accurate test results.
[0036] The filter self-cleaning assembly is used to intercept and discharge particulate matter in wastewater to the outside of the wastewater sampling tube 6. The filter self-cleaning assembly includes a filter cover 10 fixedly connected between the sampling tube 1 and the wastewater sampling tube 6. The inner top of the filter cover 10 is in contact with a lifting plate 12. The diameter of the lifting plate 12 is larger than the inner diameter of the wastewater sampling tube 6 and smaller than the inner diameter of the filter cover 10. This ensures that wastewater can enter the filter cover 10 when sampling wastewater. At the same time, when the wastewater in the wastewater sampling chamber 4 is output to the wastewater detection device body external to the exhaust gas, the wastewater sampling tube 6 can be blocked to ensure that all wastewater can be input into the wastewater detection device body.
[0037] Two limiting rods 14 slide through the top of the lifting plate 12, and a limiting block is fixedly installed on the surface of each limiting rod 14 to prevent the lifting plate 12 from blocking the top of the sampling cylinder 1 under negative pressure.
[0038] The limiting rod 14 is fixedly installed inside the filter cover 10. Two first springs 15 are connected between the bottom of the lifting plate 12 and the top of the sampling cylinder 1. Multiple anti-clogging needles 13 are fixedly installed on the top of the lifting plate 12. The surfaces of the multiple anti-clogging needles 13 are slidably connected to the filter plate 11. The filter plate 11 is fixedly installed inside the wastewater sampling pipe 6. When the piston 16 in the wastewater sampling chamber 4 moves inward to sample the wastewater through the wastewater sampling pipe 6, under the negative pressure in the wastewater sampling chamber 4 and the filter cover 10, the lifting plate 12 moves inward and compresses the two first springs 15 until each anti-clogging needle 13 is disengaged from the filter plate 11, allowing the wastewater to pass through. After being filtered by the filter plate 11 in the wastewater sampling pipe 6, the wastewater enters the medium wastewater sampling chamber 4. When the piston 16 moves towards the wastewater sampling pipe 6 and sends the wastewater in the wastewater sampling chamber 4 into the wastewater delivery pipe 8, the lifting plate 12 will be reset under the push of the two first springs 15. At the same time, it will drive each anti-clogging needle 13 to pass through each filter hole on the filter plate 11, which can push out the particles intercepted on the filter plate 11 and block the filter plate 11. This achieves unidirectional flow in the wastewater sampling pipe 6, thereby achieving the effect of automatic cleaning of the filter plate 11, preventing the filter plate 11 from becoming clogged, and eliminating the need to replace the filter plate 11.
[0039] Furthermore, the surfaces of the exhaust gas sampling chamber 3 and the wastewater sampling chamber 4 are each provided with sliding holes 22, and the two sliding holes 22 are respectively slidably connected to the two right-angle rods 17. The opposite ends of the two right-angle rods 17 are fixedly connected to the second springs 18, and the other ends of the two second springs 18 are respectively fixedly connected to the opposite ends of the exhaust gas sampling chamber 3 and the wastewater sampling chamber 4. When the two handles 19 are pressed, the second springs 18 will be compressed through the right-angle rods 17, so that when the handles 19 are released, the piston 16 can move in the opposite direction, squeezing the exhaust gas or wastewater into the exhaust gas conveying pipe 7 or the wastewater conveying pipe 8, and automatically conveying it to the exhaust gas and wastewater detection device for detection.
[0040] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.
[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
