Description

Technical Field

[0001] This utility model relates to the field of flue gas testing technology, and in particular to a device for testing the sealing performance of flue gas ducts. Background Technology

[0002] The airtightness test of the public flue system in residential buildings directly affects the smoke exhaust effect of the flue system in the residents' homes. During the construction and decoration stage, it is necessary to manually check whether the public flue is "leaking" and find the leakage point, and then repair the public flue. The public flue in high-rise buildings is long, and the workload of checking each floor and each household is large. Therefore, a fast and effective flue airtightness test method is needed. Currently, existing methods and devices for detecting the sealing performance of flue gas ducts have many shortcomings. For example, the most common method involves installing a first flow sensor and a second sensor at the flue gas inlet and outlet, respectively. Air is then introduced into the flue through the inlet, and the airflow data from the first and second sensors are monitored. The difference between these data is compared; if the difference is within a certain standard range, the flue gas duct is considered to be leak-free. This method is not only complex to operate but also requires specialized technicians, resulting in high costs. Furthermore, other detection methods suffer from low accuracy, failing to accurately determine the location and extent of sealing defects in the flue gas duct, thus failing to meet practical engineering requirements. In view of this, there is an urgent need for a device for testing the sealing performance of flue gas ducts to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a device for detecting the sealing performance of flue gas ducts, which solves the above-mentioned problems.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a device for detecting the sealing performance of flue gas ducts, comprising: The test chamber includes a test box, a blower, an adjustment assembly, an output pipe, a connecting hose, and a smoke generator. The test box is equipped with a partition plate that divides it into a smoke generator placement chamber and a blower placement chamber. The smoke generator is placed in the smoke generator placement chamber, and the blower is installed in the blower placement chamber. The blower's air inlet pipe passes through the partition plate and connects to the smoke generator. One end of the output pipe is connected to the blower's air outlet pipe, and the other end passes through the side wall of the blower placement chamber and is detachably connected to the connecting hose. The adjustment assembly is movably connected to the end of the smoke generator placement chamber away from the partition plate.

[0005] Preferably, the adjustment assembly includes an end cap, an adjustment rod, and a piston plate. The piston plate is slidably connected to the smoke generator placement cavity. The end cap is detachably connected to one end of the smoke generator placement cavity. One end of the adjustment rod passes through the end cap and is fixedly connected to the piston plate. The adjustment rod is threadedly connected to the end cap.

[0006] Preferably, the testing box is cylindrical, with at least one support frame fixedly connected to its curved side wall, and an openable door is provided on the curved side wall of the testing box.

[0015] 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.

[0016] Please see the appendix Figure 1-2 An apparatus for testing the sealing performance of flue gas ducts, comprising: The test chamber 1 comprises a blower 2, an adjustment assembly 3, an output pipe 4, a connecting hose 5, and a smoke generator 6. The test chamber 1 is equipped with a partition plate 12 that divides it into a smoke generator placement chamber 10 and a blower placement chamber 11. The smoke generator 6 is placed in the smoke generator placement chamber 10. The blower 2 is installed in the blower placement chamber 11, and the air inlet pipe of the blower 2 passes through the partition plate 12 and is connected to the smoke generator 6. One end of the output pipe 4 is connected to the air outlet pipe of the blower 2, and the other end passes through the side wall of the blower placement chamber 11 and is detachably connected to the connecting hose 5. The adjustment assembly 3 is movably connected to the end of the smoke generator placement chamber 10 away from the partition plate 12. In practical use, connect the connecting hose 5 to the PVC pipe on the wall of the smoke duct, then turn on the smoke generator 6 and place it in the smoke generator placement chamber 10. At the same time, turn on the blower 2. During the operation of the blower 2, the smoke released by the smoke generator 6 enters through the air inlet pipe of the blower 2 and enters the ventilation pipe 4 through the air outlet pipe of the blower 2. Finally, it is gradually discharged into the smoke duct through the connecting hose 5. After the smoke has been discharged into the smoke duct for a period of time, you can directly observe whether there is smoke discharged from the window of the floor to quickly determine the location of the leak in the smoke duct. This method is simple and convenient, not only low in cost, but also highly efficient in leak detection. The smoke generator 6 can be a commonly used fire training smoke generator on the market.

[0017] Specifically, the adjustment assembly 3 includes an end cap 30, an adjustment rod 31, and a piston plate 32. The piston plate 32 is slidably connected to the smoke generator placement cavity 10. The end cap 30 is detachably connected to one end of the smoke generator placement cavity 10. One end of the adjustment rod 31 passes through the end cap 30 and is fixedly connected to the piston plate 32. The adjustment rod 31 is also threadedly connected to the end cap 30. Considering that the length of the smoke ducts in different buildings varies, the size of the smoke generators 6 used also varies. Therefore, the test box 1 is equipped with a corresponding adjustment component 3 to change the size of the smoke generator placement cavity 10. In actual use, after the smoke generator 6 is placed in the smoke generator placement cavity 10, the adjustment component 3 is installed on one end of the test box 1 through the end cap 30. Then, by rotating the adjustment rod 31, the relative position of the adjustment rod 31 can be changed, thereby changing the actual position of the piston plate 32 in the smoke generator placement cavity 10, so as to adjust the actual application volume of the smoke generator placement cavity 10.

[0018] Specifically, the testing box 1 is cylindrical, with at least one support frame 13 fixedly connected to its curved side wall, and an openable door 14 on the curved side wall of the testing box 1. Considering that the cylindrical structure of the testing box 1 is prone to positional displacement, a support frame 13 is provided for fixing its position. At the same time, in order to facilitate the removal and placement of the smoke generator 6, a door 14 is also provided. It should be noted that the width of the door 114 can also be changed to accommodate the position of the blower 2, making it easier to disassemble and assemble the blower 2.

[0019] Specifically, the blower 2 is equipped with a power cord 20. The end of the power cord 20 away from the blower 2 passes through the side wall of the test box 1 and is located on the outside of the test box 1. Considering the convenience of starting and closing the blower 2, the power cord 20 passes through the side wall of the test box 1 and is located on its outside so as to connect to an external power source.

[0020] Specifically, the curved sidewall of the testing box 1 is provided with a transparent observation window 15, and the edge of the transparent observation window 15 is provided with a volume scale 150. In the process of adjusting the actual application space of the smoke generator placement cavity 10 by adjusting the adjustment component 3, in order to achieve a precise and intuitive adjustment effect, a transparent observation window 15 is provided on the curved sidewall of the testing box 1. The position of the piston plate 30 can be seen through the transparent observation window 15, and the actual application volume of the smoke generator placement cavity 10 can be precisely adjusted by referring to the scale.

[0021] Example 2 Please refer to 3-5 Considering that in practical applications, there may be some small leaks on the surface of the flue, and even if smoke leaks from these leaks, they may not be noticeable without careful inspection, the detection device has been further optimized to address the above situation. Specifically, the testing box 1 is equipped with a matching packing assembly 7 and a material bucket 8. The material bucket 8 is located outside the testing box 1, and the packing assembly 7 is located inside the blower placement cavity 11. The packing assembly 7 is connected to the material bucket 8 and the output pipe 4 respectively. The packing assembly 7 includes a feed pipe 70, a circular outer shell 71, a feed impeller 72, a discharge pipe 73, and a switching valve 74. One end of the feed pipe 70 passes through the curved side wall of the detection box 1 and is fixedly connected to the material barrel 8, while the other end is fixedly connected to the upper end of the circular outer shell 71. One end of the discharge pipe 73 is fixedly connected to the output pipe 4, while the other end is fixedly connected to the lower end of the circular outer shell 71. The feed impeller 72 is bearing-connected inside the circular outer shell 71, and the switching valve 74 is installed in the middle position of the feed pipe 70. To address the issue of small leaks in the flue gas duct being difficult to detect, a material tank 8 and a filling assembly 7 were installed on the original detection box 1. The material tank 8 can be filled with brightly colored organic powder pigments or powdered fillers with special odors. As the blower 2 carries the smoke into the flue gas duct, the airflow causes the feed impeller 52 to rotate. The powdered fillers in the material tank 8 slowly enter the output pipe 4 along with the feed impeller 52, and then enter the flue gas duct along with the smoke. When there are small leaks in the flue gas duct, the smoke leaking from these leaks is easier to distinguish than plain smoke because it contains colored pigments or powders with special odors.

[0022] Specifically, a micro motor matching the feed impeller 72 is provided on the side wall of the circular outer shell 71. Considering that the airflow in the output pipe 4 may not be able to drive the feed impeller 52 to rotate, in this case, the feed impeller 72 can be driven to rotate by the micro motor (not shown in the figure) set outside the circular outer shell 71, thereby completing the purpose of adding colored pigments or powder fillers with special flavors into the smoke.

[0023] 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.
