Description

Technical Field

[0001] This utility model relates to the field of gas analyzer technology, specifically a continuous gas analyzer. Background Technology

[0002] The transportation and transmission of chemical gases are indispensable in industrial production processes, as are the purification and emission of industrial waste gases. Gas safety is an essential task in industrial production, so the detection of various gases at each stage of industrial production is particularly important. In existing production processes, gas analyzers are often used to analyze the different components in the gases.

[0003] Traditional gas analyzers are used by directly introducing the air to be tested into them. However, air often contains impurities, such as larger dust particles or other debris. Directly introducing air into the gas analyzer can cause blockages in the internal pipes, and dust can adhere to the monitoring probe inside the gas analyzer, thus affecting the analytical accuracy. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a continuous gas analyzer that has the advantages of filtering air and being easy to use, thus solving the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a continuous gas analyzer, comprising a device body, an exhaust pipe fixedly mounted on the outer wall of the device body, an air inlet pipe fixedly mounted on the outer wall of the device body, a support plate mounted on the outer wall of the device body, a connecting pipe fixedly mounted in the inner cavity of the support plate, a support frame fixedly mounted on the outer wall of the device body, a drive motor fixedly mounted on the outer wall of the support frame, a drive gear fixedly mounted on the power output shaft of the drive motor, a rotating frame rotatably connected to the inner cavity of the support frame, a rotating rod fixedly mounted on the outer wall of the rotating frame, a filter cylinder fixedly mounted in the inner cavity of the rotating frame, a filter groove formed in the inner cavity of the filter cylinder, a filter box movably sleeved in the inner cavity of the filter cylinder, a filter plate installed in the inner cavity of the filter box, an adsorption plate installed in the inner cavity of the filter box, a fixed magnet fixedly mounted on the outer wall of the filter cylinder, an air inlet hole formed in the outer wall of the rotating frame, and a sealing cover movably sleeved on the top of the filter box.

[0006] As a preferred embodiment of this utility model, the outer wall of the rotating rod passes through the inner cavity of the support frame, and the outer wall of the rotating rod meshes with the outer wall of the drive gear.

[0007] As a preferred technical solution of this utility model: the inner wall diameter of the filter cylinder matches the inner wall diameter of the air inlet pipe and the connecting pipe, and there are two rotating rods, which are respectively installed on the outer wall of the rotating frame on both sides.

[0008] As a preferred technical solution of this utility model: the inner wall shape of the filter tank matches the outer wall shape of the filter box, and the filter box is made of metal iron.

[0009] As a preferred technical solution of this utility model: the top of the fixed magnet is in contact with the outer wall of the top of the filter box, and the inner wall diameter of the air inlet is matched with the inner wall diameter of the filter cylinder.

[0010] As a preferred technical solution of this utility model: the adsorption plate is made of coarse-pore woven fabric, and the outer wall shape of the filter plate and the adsorption plate matches the inner wall shape of the filter box.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This continuous gas analyzer, through the filter cartridge installed on the outer wall of the support frame, and the filter plate and adsorption plate installed in the inner cavity of the filter cartridge, allows larger impurities in the air to be filtered first by the filter plate when the air enters the inner cavity of the equipment body, and then pass through the adsorption plate, where dust particles in the air are adsorbed and filtered. Thus, after the air enters the inner cavity of the equipment body, larger impurities and dust particles in the air can be removed, avoiding any impact on the normal operation of the equipment body.

[0013] 2. This continuous gas analyzer uses a drive motor mounted on the outer wall of the support frame to rotate the rotating frame, allowing for easy replacement of the filter cartridge. Furthermore, when maintaining the filter box inside the filter cartridge, the filter box can be pulled directly out of the filter cartridge, making it very convenient. This allows for better and more efficient air filtration and adsorption, resulting in more accurate measurement data. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1 - Figure 5 A continuous gas analyzer includes a device body 1, an exhaust pipe 2 and an air inlet pipe 3 fixedly mounted on the outer wall of the device body 1, a support plate 5 mounted on the outer wall of the device body 1, a connecting pipe 4 fixedly mounted in the inner cavity of the support plate 5, a support frame 6 fixedly mounted on the outer wall of the device body 1, a drive motor 7 fixedly mounted on the outer wall of the support frame 6, a drive gear 8 fixedly mounted on the power output shaft of the drive motor 7, a rotating frame 9 rotatably connected to the inner cavity of the support frame 6, a rotating rod 10 fixedly mounted on the outer wall of the rotating frame 9, a filter cylinder 11 fixedly mounted in the inner cavity of the rotating frame 9, a filter groove 12 formed in the inner cavity of the filter cylinder 11, a filter box 13 movably sleeved in the inner cavity of the filter cylinder 11, a filter plate 14 and an adsorption plate 15 installed in the inner cavity of the filter box 13, a fixing magnet 16 fixedly mounted on the outer wall of the filter cylinder 11, an air inlet 17 formed on the outer wall of the rotating frame 9, and a sealing cover 18 movably sleeved on the top of the filter box 13.

[0022] In the above structure, by providing an exhaust pipe 2 and an air inlet pipe 3 on both sides of the outer wall of the device body 1, and a support frame 6 on the outer wall of the device body 1, gas is supplied to the inner cavity of the device body 1 through the air inlet pipe 3, so that the gas to be detected can enter the inner cavity of the device body 1, and after the detection is completed, the gas can be discharged outward from the inner cavity of the exhaust pipe 2.

[0023] In a preferred embodiment, the outer wall of the rotating rod 10 passes through the inner cavity of the support frame 6, and the outer wall of the rotating rod 10 meshes with the outer wall of the drive gear 8.

[0024] In the above structure, the rotating rod 10 is provided on the outer wall of the rotating frame 9, and the outer wall of the rotating rod 10 passes through the inner cavity of the support frame 6. Under the action of the drive motor 7, the drive gear 8 can be driven to rotate. Since the outer wall of the drive gear 8 meshes with the outer wall of the rotating rod 10, the rotating rod 10 is driven, and the rotating frame 9 rotates with the rotation of the rotating rod 10.

[0025] In a preferred embodiment, the inner wall diameter of the filter cartridge 11 matches the inner wall diameter of the air inlet pipe 3 and the connecting pipe 4, and there are two rotating rods 10, which are respectively installed on the outer walls of the rotating frames 9 on both sides.

[0026] In the above structure, the filter cylinder 11 installed on the inner wall of the rotating frame 9 can drive the rotating rod 10 under the action of the drive motor 7, so that the rotating frame 9 can rotate on the outer wall of the support frame 6, thereby enabling the two filter cylinders 11 installed on the outer wall of the rotating frame 9 to correspond sequentially with the inner cavity of the air inlet pipe 3.

[0027] In a preferred embodiment, the inner wall shape of the filter tank 12 matches the outer wall shape of the filter box 13, which is made of iron.

[0028] In the above structure, by using the filter groove 12 opened in the inner cavity of the filter cylinder 11 and the filter box 13 installed in the inner cavity of the filter cylinder 11, when gas is introduced into the inner cavity of the device body 1, the gas can pass through the inner cavity of the filter box 13. After the gas enters the inner cavity of the filter box 13, it will be filtered by the filter plate 14 and the adsorption plate 15 respectively.

[0029] In a preferred embodiment: the top of the fixed magnet 16 contacts the outer wall of the top of the filter box 13, and the inner wall diameter of the air inlet 17 matches the inner wall diameter of the filter cartridge 11.

[0030] In the above structure, after the filter box 13 is placed into the inner cavity of the filter tank 12 by the fixed magnet 16 set on the outer wall of the filter cylinder 11, the outer wall of the filter box 13 will come into contact with the outer wall of the fixed magnet 16, and then the outer wall of the filter box 13 will be attracted under the action of the fixed magnet 16, thereby fixing the filter box 13 and installing the filter box 13 into the inner cavity of the filter cylinder 11.

[0031] In a preferred embodiment, the adsorption plate 15 is made of coarse-pore woven fabric, and the outer wall shape of the filter plate 14 and the adsorption plate 15 matches the inner wall shape of the filter box 13.

[0032] In the above structure, the filter plate 14 and the adsorption plate 15 installed in the inner cavity of the filter box 13 can block larger debris entering the inner cavity of the filter box 13 under the action of the filter plate 14. Then, the air passes through the outer wall of the filter plate 14 and comes into contact with the outer wall of the adsorption plate 15, and the dust in the air is adsorbed under the action of the adsorption plate 15.

[0033] Working Principle: During use, when air analysis is required, air is introduced into the inner cavity of the device body 1. The drive motor 7 is activated, which in turn drives the drive gear 8 to rotate, thereby driving the rotating rod 10. This causes the rotating frame 9 to rotate along the outer wall of the support frame 6. During this rotation, the inner cavity of the filter cartridge 11 aligns with the inner cavities of the inlet pipe 3 and the connecting pipe 4. The filter box 13 is then inserted into the inner cavity of the filter tank 12, ensuring that the outer wall of the filter box 13 is in contact with the outer wall of the fixed magnet 16. Air is then introduced into the inner cavity of the connecting pipe 4. After entering the inner cavity of the filter cartridge 11, the air enters the inner cavity of the filter box 13. The filter plate 14 first processes larger impurities in the air, preventing them from entering the inner cavity of the device body 1. Then, the air is adsorbed... The outer wall of plate 15, being made of non-woven fabric, can adsorb some suspended dust particles in the air, preventing debris and dust particles from entering the inner cavity of the equipment body 1. After a period of use, the drive motor 7 drives the drive gear 8 to rotate, thereby rotating the support frame 6 and replacing the filter cartridge 11. Another filter cartridge 11 can then be installed between the outer wall of the air inlet pipe 3 and the connecting pipe 4. The inner cavity of the replaced filter cartridge 11 is then cleaned, and the filter box 13 is pulled upward to detach from the inner cavity of the filter cartridge 11. The sealing cover 18 is then removed from the top of the filter box 13 to maintain the filter plate 14 and adsorption plate 15 inside the filter box 13, ensuring the normal replacement and use of the filter cartridge 11.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
