Description
Technical Field
[0001] This utility model relates to the field of waste gas detection and sampling equipment, and in particular to a waste gas sampling device for industrial waste gas detection. Background Technology
[0002] Industrial waste gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within a factory area. Waste gas sampling devices are important tools for industrial waste gas detection, and their performance directly affects the accuracy of the detection results. Traditional industrial waste gas sampling devices have some problems, such as poor sealing, which can easily lead to waste gas leakage or outside air entering the sampling device, thus affecting the accuracy of the detection results. Some sampling devices are also inconvenient to clean and maintain, increasing the difficulty and cost of use.
[0003] A search revealed Chinese Patent Publication No. CN221038243U, which discloses a waste gas sampling device for industrial waste gas detection. The device includes an exhaust pipe and a fixed cover. A fixed block is installed at the lower end of the exhaust pipe.

The fixed cover is located below the fixed block, and a connecting hole is formed at the upper end of the fixed cover, corresponding to the position of the through hole. A fixed rod is installed at the top center of the fixed cover. The outer surface of the fixed rod is rotatably connected to a base plate via a bearing, and the base plate is slidably connected to the lower end of the fixed cover. A ring-shaped rack is installed on the side of the base plate, meshing with a gear. A motor is installed on the upper end of the gear, and the motor is fixedly connected to the fixed cover.

Therefore, an industrial waste gas sampling device for detection is proposed to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figures 1-2 This utility model provides an embodiment of an industrial waste gas sampling device, comprising a sampling box 1, which provides support and protection for the equipment. An observation door 2 is detachably connected to the front surface of the sampling box 1, allowing operators to directly observe the working status of the components within the sampling box 1, thus improving the convenience of equipment operation and adjustment. A sampling tube 3 is fixedly installed on the left surface of the sampling box 1, providing a sampling channel for waste gas sampling. A mounting base 4 is fixedly installed at the left end of the sampling tube 3, allowing the addition of external filters of different models to filter impurities in the waste gas during the sampling process, thus improving the convenience of adding filters to the sampling tube 3. A motor 5 is fixedly installed on the right surface of the sampling box 1, providing power to an auxiliary component 7. A cooling component 6 is installed on the outer wall of the sampling tube 3, and the auxiliary component 7 is installed inside the sampling box 1.
[0025] Reference Figures 2-4 The cooling component 6 includes a heat-absorbing jacket 61, which, in conjunction with a condensate pipe 63, absorbs heat transferred from the high-temperature exhaust gas inside the sampling tube 3, reducing the exhaust gas temperature and preventing damage to subsequent testing equipment. Its hollow structure design enhances heat exchange efficiency. The outer wall of the sampling tube 3 is fitted with a condensate pipe 63, filled with condensate. During circulation, the condensate absorbs heat transferred from the sampling tube 3, thus cooling the tube. The tight fit between the condensate pipe and the heat-absorbing jacket 61 ensures excellent heat transfer, guaranteeing the timeliness and effectiveness of the cooling process. For efficiency, the heat absorption jacket 61 has a hollow internal structure. The inner wall of the heat absorption jacket 61 is in close contact with the outer wall of the condensate pipe 63. The heat absorption jacket 61 is rotatably connected to the outer wall of the sampling tube 3 through the condensate pipe 63. A joint 64 is fixedly installed at the left end of the condensate pipe 63, and a joint 65 is fixedly installed at the right end of the condensate pipe 63. Joints 64 and 65 are respectively installed at both ends of the condensate pipe 63, which serves to connect the condensate pipe 63 with the external condensate circulation system. They also provide an interface for the installation of the condensate auxiliary pipe 66, making it easy to adjust the connection method of the condensate pipe 63 according to actual needs.
[0026] Reference Figures 2-4A condenser sub-pipe 66 is detachably connected between section head 1 64 and section head 2 65. The length of the condenser sub-pipe 66 can be flexibly adjusted according to the actual space and cooling requirements, further enhancing the heat dissipation and cooling capacity of the entire cooling component 6 and improving the adaptability to exhaust gas temperature under different working conditions. The outer walls of section head 1 64 and section head 2 65 are fixedly installed in the groove on the outer wall of the heat absorption sleeve 61. Multiple sets of evenly distributed heat-conducting strips 62 are fixedly connected to the outer surface of the heat absorption sleeve 61. The heat-conducting strips 62 are evenly distributed on the outer surface of the heat absorption sleeve 61, increasing the contact area between the heat absorption sleeve 61 and the surrounding environment, accelerating the dissipation of heat to the outside, improving the overall heat dissipation efficiency of the cooling component 6, and enabling the heat absorption sleeve 61 to more effectively absorb the heat transferred from the sampling tube 3 and quickly dissipate it.
[0027] Reference Figures 1-3 The auxiliary component 7 includes an auxiliary gear 71, which is fixedly connected to the left end of the reciprocating lead screw 72. The auxiliary gear 71 converts the power output from the motor 5 into the rotational motion of the reciprocating lead screw 72, providing a power source for the movement of the moving block 74. The precise meshing of the teeth of the auxiliary gear 71 with the gear plate seat 67 ensures the stability and accuracy of the power transmission. The right end of the heat absorption sleeve 61 is fixedly connected to the gear plate seat 67. The teeth on the outer wall of the auxiliary gear 71 mesh with the teeth on the outer wall of the gear plate seat 67. The rotation of the auxiliary gear 71 drives the gear plate seat 67. The rotation causes the cooling component 6 to rotate on the outer wall of the sampling tube 3, improving the uniformity of cooling and heat dissipation on the outer wall of the sampling tube 3. The output shaft of the motor 5 is fixedly mounted with a reciprocating screw 72. A slider 73 is threadedly connected to the thread on the outer wall of the reciprocating screw 72. The slider 73 moves linearly with the rotation of the reciprocating screw 72. As a key component connecting the moving block 74 and the reciprocating screw 72, it transmits the rotational motion of the reciprocating screw 72 to the moving block 74, driving the moving block 74 and its components to perform corresponding actions, while ensuring the smoothness and accuracy of the movement process.
[0028] Reference Figures 2-4A movable block 74 is fixedly connected to the outer wall of the slider 73. The movable block 74 changes its position as the slider 73 moves, thereby driving the rotating seat 75 and fan 77 to move accordingly, thus adjusting the position of the fan 77 to adapt to different heat dissipation or exhaust gas treatment requirements. A rotating seat 75 is fixedly installed on the upper surface of the movable block 74, providing a mounting base and rotational support for the fan 77. The detachable design facilitates the installation, disassembly, and maintenance of the fan 77, ensuring that the fan 77 can rotate and dissipate heat at the appropriate position, angle, and speed. (The sampling box 1 is internal.) The top of the rotating block 74 is fixedly connected to a limiting rod 76, which guides and limits the movement of the moving block 74, ensuring that the moving block 74 moves smoothly along the predetermined path and preventing the moving block 74 from deviating or shaking during the movement. The moving block 74 is connected through the outer wall of the limiting rod 76. The rotating shaft of the rotating seat 75 is detachably connected to a fan 77, which is driven by the auxiliary component 7 to rotate and generate airflow to ventilate and dissipate heat inside the sampling box 1, preventing the temperature from becoming too high due to the accumulation of heat generated during the sampling and treatment of exhaust gas, which would affect the normal operation of the equipment and enhance the cooling and heat dissipation effect of the equipment.
[0029] Working principle:
[0030] Industrial waste gas enters the sampling box 1 through the sampling tube 3. The sampling tube 3 serves as the sampling channel for the waste gas, ensuring that the waste gas can be smoothly introduced into the device for subsequent treatment and testing. Before the waste gas enters the sampling tube 3, different types of external filters can be added through the mounting base 4 to filter impurity particles in the waste gas, preventing impurity particles from entering the sampling tube 3 and the sampling box 1, avoiding damage to subsequent testing equipment or interference with test results, and improving the accuracy of sampling and testing.
[0031] After the high-temperature exhaust gas enters the sampling tube 3, the heat-absorbing jacket 61 is tightly fitted to the outer wall of the sampling tube 3. Its hollow internal structure is filled with condensate, and the condensate pipe 63 is also filled with condensate. During circulation, the condensate absorbs the heat transferred from the high-temperature exhaust gas in the sampling tube 3, lowering the exhaust gas temperature and preventing damage to subsequent testing equipment. The tight fit between the heat-absorbing jacket 61 and the condensate pipe 63 ensures good heat transfer, guaranteeing the timeliness and effectiveness of the cooling process. Simultaneously, the heat-conducting strips 62 are evenly distributed on the outer surface of the heat-absorbing jacket 61, increasing the contact area between the heat-absorbing jacket 61 and the surrounding environment, accelerating heat dissipation, improving the overall heat dissipation efficiency of the cooling component 6, and further enhancing the cooling effect.
[0032] Motor 5 provides power to auxiliary component 7. Motor 5 drives reciprocating screw 72 to rotate. The reciprocating screw 72, through its threaded engagement with slider 73, converts the rotational motion into linear motion of slider 73, thereby driving the moving block 74, its rotating seat 75, and fan 77 to move. Limiting rod 76 guides and limits the movement of moving block 74, ensuring that moving block 74 moves smoothly along a predetermined path. By adjusting the position of moving block 74, the position of fan 77 can be changed to adapt to different heat dissipation requirements or exhaust gas treatment requirements. The fan 77 is driven by the auxiliary component 7 to rotate, generating airflow to ventilate and dissipate heat inside the sampling box 1, preventing the temperature from becoming too high due to the accumulation of heat generated during the sampling and treatment of exhaust gas, which would affect the normal operation of the equipment. The auxiliary gear 71 meshes with the gear plate seat 67. When the motor 5 drives the auxiliary gear 71 to rotate, it drives the gear plate seat 67 and the heat absorption sleeve 61 to rotate on the outer wall of the sampling tube 3, which improves the uniformity of cooling and heat dissipation on the outer wall of the sampling tube 3. The staff can directly observe the working status of the internal components of the sampling box 1 through the observation door 2, which improves the convenience of equipment operation adjustment and facilitates timely detection of abnormalities and maintenance.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
