Description

Technical Field

[0001] The utility model specifically relates to a flue gas preprocessor with a positioning function, belonging to the technical field of flue gas preprocessors. Background Art

[0002] Flue gas refers to the mixture of gas and soot, which is the main cause of air pollution in residential areas. The composition of flue gas is very complex. Before detecting flue gas, it is usually necessary to preprocess the flue gas. During the preprocessing process, it is necessary to remove dust and water vapor from the flue gas.

[0003] For example, the publication number is: CN218067308U, a flue gas preprocessor. This utility model relates to the technical field of flue gas pretreatment, including a flue gas preprocessor. One end of the flue gas preprocessor is fixedly installed with a sampling rod. The outer wall of the sampling rod is provided with a conical pipe sleeve. The outer wall of the conical pipe sleeve is provided with external threads. Two threaded holes are opened on the outer wall of the conical pipe sleeve, and bolts are threadedly connected to the interiors of the two threaded holes. First, the user screws the conical pipe sleeve into the sampling hole opened on the flue gas discharge pipe, and then holds the flue gas preprocessor by hand and inserts the sampling rod into the interior of the conical pipe sleeve. At this time, the user rotates the bolt, and the bolt drives the clamping ring to move downward. By setting the clamping ring to move downward, it is convenient to fix the sampling rod in the conical pipe sleeve, so that when the user's arm is fatigued when holding the flue gas preprocessor horizontally, the user can loosen it for a short time to relieve the fatigue of the arm, thus reducing the labor intensity of the personnel.

[0004] However, in actual use, it is difficult to position the sampling depth of the sampling rod, and the temperature of the sampling rod is relatively high during sampling, which is easy to scald the operator. Moreover, after sampling, it cools slowly and is not convenient for quick storage, thus being inconvenient to use. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide a flue gas preprocessor with a positioning function for the deficiencies of the prior art, so as to achieve the purpose of being able to position the sampling depth, prevent scalding during use, and quickly cool the sampling rod.

[0006] The present utility model realizes the above object through the following technical solutions.

The main body is fixedly connected to the handle holder. The sleeve is snap-fitted with the handle holder. Linear-array limiting grooves are formed at the upper and lower ends of the sleeve. Limiting strips are symmetrically and fixedly installed at both ends of the sleeve. A slidable limiting baffle is sleeved outside the sleeve. An air pump is slidably connected to the upper end of the handle holder. The air pump is connected to the inside of the sleeve. When in use, the main body is used to adjust the highest temperature of the sampling rod and the lowest temperature of the condenser to form a temperature difference so that the moisture contained in the flue gas is condensed and then stored in the water storage box.

A sliding connection groove is formed at the lower end of the air pump. The air pump and the handle holder are slidably connected through the sliding connection boss and the sliding connection groove.

[0009] Preferably, in order to facilitate the connection and disconnection of the rubber tube and the sleeve, a rubber tube is installed at the output end of the air pump. A threaded connection tube is fixedly installed at the end of the rubber tube. A threaded air inlet is formed at one side of the upper end of the sleeve.

[0010] Preferably, in order to facilitate the installation and disassembly of the sleeve, a rotary connection groove is formed on one side of the handle holder. A rotary connection rod is fixedly installed on one side of the sleeve. The rotary connection rod is snap-fitted with the rotary connection groove.

[0011] Preferably, in order to facilitate the sliding adjustment of the slidable limiting baffle, baffle handles are symmetrically formed on both sides of the slidable limiting baffle. Grooves are symmetrically formed inside the slidable limiting baffle. Springs are fixedly connected inside the grooves. One end of each spring is fixedly connected to a limiting block.

[0012] Preferably, in order to fix the slidable limit baffle when it is adjusted to an ideal position, the slidable limit baffle is mutually engaged with the limit groove through the limit block, and one end of the sleeve is provided with air outlets in a circular array.

[0013] Preferably, in order to limit the rotation of the slidable limiting baffle to prevent the limiting block from escaping from the limiting groove, limiting notches are symmetrically provided on the inner side of the slidable limiting baffle, and the limiting notches are engaged with each other through the limiting strip.

[0014] The beneficial effects of the utility model are as follows: when in use, the sampling depth of the sampling rod can be positioned by adjusting the slidable limit baffle, the sleeve can be quickly installed and removed by rotating the connecting rod and the rotating connecting groove, and the air pump and the sleeve can prevent burns during use and facilitate rapid cooling and heat dissipation of the sampling rod.

DETAILED DESCRIPTION

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 As shown, a flue gas preprocessor with a positioning function includes a main unit 1, a sampling rod 2, and a sleeve 3. A handle holder 4 is fixedly installed on one side of the sampling rod 2 to facilitate the operator to better control the direction of the sampling rod 2. The main unit 1 is fixedly connected to the handle holder 4, and the sleeve 3 is snap-connected to the handle holder 4 to facilitate the disassembly and installation of the sleeve 3. Linear array limiting slots 301 are provided at the upper and lower ends of the sleeve 3, and limiting bars 302 are symmetrically and fixedly installed at both ends of the sleeve 3. A slidable limiting baffle 5 is sleeved outside the sleeve 3 to facilitate positioning the sampling rod 2. An air pump 6 is slidably connected to the upper end of the handle holder 4, and the air pump 6 is connected to the inside of the sleeve 3 to facilitate quickly cooling the sampling rod 2 through air flow.

[0023] As Figure 1 shown in 2 As shown, a slidable connection boss 401 is fixedly installed at the upper end of the handle holder 4, and a slidable connection groove 601 is provided at the lower end of the air pump 6. Through the slidable connection boss 401 and the slidable connection groove 601, it is convenient to slidably connect the air pump 6 to the handle holder 4. The output end of the air pump 6 is fixedly connected to a rubber tube 602, and then threadedly connected to an air inlet 303 through a threaded connection tube 603. Air outlet openings 305 are provided in a circumferential array on one side of the sleeve 3 to facilitate the air pump 6 to output air flow inside the sleeve 3 to quickly cool and lower the temperature of the sampling rod 2. A rotary connection groove 402 is provided on one side of the handle holder 4, and a rotary connection rod 304 is fixedly installed on one side of the sleeve 3. By inserting the rotary connection rod 304 into the rotary connection groove 402 and rotating, the sleeve 3 is snap-connected to the handle holder 4 to facilitate the installation and disassembly of the sleeve 3.

[0024] As Figure 1 shown in Figure 3 As shown, the operation keys 102 on one side of the main unit 1 can adjust the maximum temperature of the sampling rod 2 and the minimum temperature of the condenser 104 to facilitate forming a temperature difference to condense the water vapor in the inhaled flue gas and store it in the water storage box 105. After the sampled flue gas is free of water vapor interference, it can be more conveniently inspected. Limiting bars 302 are symmetrically and fixedly installed on both sides of the sleeve 3, and limiting notches 505 are symmetrically provided on the inner side of the slidable limiting baffle 5. By slidingly connecting the limiting bars 302 and the limiting notches 505, it is convenient to limit the rotation of the slidable limiting baffle 5 during sliding adjustment.

[0025] As Figure 3 shown inFigure 5 As shown, on both sides of the slidable limit baffle 5, baffle handles 501 are symmetrically provided, which facilitate subsequent operators to slide and adjust the slidable limit baffle 5 during use to achieve the sampling depth positioning of the sampling rod 2. On the inner side of the slidable limit baffle 5, grooves 502 are symmetrically provided. One end of a spring 503 in the groove 502 is fixedly connected to the groove 502, and the other end of the spring 503 is fixedly connected to a limit block 504. When the slidable limit baffle 5 is slid and adjusted through the groove 502, the spring 503 and the limit block 504 can be limited so that they are always in the groove 502. Linear arrays of limit grooves 301 are provided at the upper and lower ends of the sleeve 3. By engaging the limit block 504 with the limit groove 301, it is convenient to fix the slidable limit baffle 5 when it is adjusted to an ideal position. When adjusting the slidable limit baffle 5, the limit block 504 can be pressed by human force to squeeze the spring 503 into the groove 502. When the slidable limit baffle 5 is adjusted to the next limit groove 301, the spring 503 pops out the limit block 504 to engage with the limit groove 301, realizing the sliding adjustment and limitation of the slidable limit baffle 5.
