Description

Technical Field

[0001] This utility model relates to the field of dust removal technology for combustion furnaces of high-frequency infrared carbon-sulfur analyzers, and in particular to a dust removal device for combustion furnaces of high-frequency infrared carbon-sulfur analyzers. Background Technology

[0002] The high-frequency infrared carbon-sulfur analyzer is a precision analytical instrument that uses infrared absorption technology to determine the carbon and sulfur elements in materials. In the detection of ore samples, the combustion furnace inside the high-frequency infrared carbon-sulfur analyzer is used for high-temperature oxidation combustion of the sample to release carbon and sulfur elements. In order to remove the dust generated during the combustion process, a filter dust removal device is usually installed at the front end of the detection device of the combustion furnace of the high-frequency infrared carbon-sulfur analyzer.

[0003] In existing filtration-type dust collectors, to ensure effective dust removal during long-term use, the filter screen is typically housed in a drawer-style configuration inside the device for convenient periodic disassembly and cleaning. However, pulling out the filter screen can easily loosen the dust adhering to it, allowing it to easily diffuse into the detection device of the high-frequency infrared carbon-sulfur analyzer combustion furnace, thus affecting the dust removal efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a dust removal device for a high-frequency infrared carbon and sulfur analyzer combustion furnace, which addresses the problem that dust attached to the filter screen in a pull-out filter dust removal device is easily loosened and diffused into the combustion furnace detection device of the high-frequency infrared carbon and sulfur analyzer.

[0005] The device includes: a dust collection box, with two dust collection frames slidably connected to the inner wall of the dust collection box, and a filter screen fixedly connected to the inner wall of each dust collection frame; and an anti-overflow mechanism, which includes baffles hinged to both sides of the inner wall of the dust collection frames, fixed plates fixedly connected to both sides of the inner wall of the dust collection box, the surface of the baffles contacting the inner wall of the fixed plates, a positioning plate fixedly connected to the front end of the baffles, a positioning rod slidably connected to the inner wall of the positioning plate, and the surface of the positioning rod engaging with the front end of the dust collection frames.

[0006] In one embodiment, one end of the positioning disk is fixedly connected to a limiting block, and the inner wall of the positioning rod is slidably connected to the surface of the limiting block.

[0007] In one embodiment, an elastic rod is slidably connected to the inner wall of the positioning rod, and the surface of the elastic rod is engaged with the inner wall of the limiting block.

[0008] In one embodiment, a plurality of limiting rods are fixedly connected to the front end of the dust removal frame, and the surface of the positioning disk contacts the surface of one of the limiting rods.

[0009] In one embodiment, a spring is fixedly connected to one end of the positioning rod, and the other end of the spring is fixedly connected to one end of the positioning disk.

[0010] In one embodiment, the inner wall of the dust collector is threadedly connected to a screw, and the surface of the screw is threadedly connected to the inner wall of the dust collector frame.

[0011] In one embodiment, a magnetic ring is fixedly connected to the surface of the screw, and the dust collector is made of martensitic stainless steel. The bottom end of the magnetic ring is magnetically attached to the end of the dust collector. The screw and magnetic ring work together to lock the dust collector frame inside the dust collector, making it easy to assemble and disassemble the dust collector frame.

[0012] In one embodiment, nylon ropes are fixedly connected to the top of the screw and the surface of the elastic rod. One end of one nylon rope is fixedly connected to the end of the dust collection box, and the other end of the other nylon rope is fixedly connected to the surface of the positioning rod. The nylon ropes are used to limit the placement range of the screw and elastic rod, avoiding the risk of loss of the screw and elastic rod. Beneficial effects

[0013] 1. By cooperating with the baffle and the positioning plate, the top and bottom openings of the dust collector frame are sealed, thus preventing dust attached to the filter screen from drifting inside the dust collector box when the dust collector frame is pulled out. This prevents dust from spreading into the detection device of the high-frequency infrared carbon-sulfur analyzer combustion furnace, ensuring the dust removal effect. By cooperating with the fixing plate and the positioning rod, the baffle is stably in contact with the fixing plate, preventing dust from adhering to the side of the baffle close to the fixing plate, thus preventing dust from drifting around when the dust collector frame is pulled out of the dust collector box. 2. The positioning rod is moved on the limiting block by the spring and locked inside the dust collection frame. The elastic rod moves down inside the positioning rod and is locked inside the limiting block, thereby locking the positioning rod and ensuring the stable locking of the baffle. This ensures that the top and bottom openings of the dust collection frame are stably open, thus ensuring the dust removal effect on the combustion gas. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined Figures 1-5 This invention describes a high-frequency infrared carbon-sulfur analyzer and a combustion furnace dust removal device.

[0019] In one embodiment, a dust removal device for a high-frequency infrared carbon-sulfur analyzer combustion furnace includes: a dust removal box 100, with two dust removal frames 200 slidably connected to the inner wall of the dust removal box 100, and a filter screen 300 fixedly connected to the inner wall of the dust removal frame 200; an anti-overflow mechanism 400, including baffles 401 hinged to both sides of the inner wall of the dust removal frame 200, fixed plates 402 fixedly connected to both sides of the inner wall of the dust removal box 100, the surface of the baffles 401 contacting the inner wall of the fixed plates 402, a positioning plate 403 fixedly connected to the front end of the baffles 401, a positioning rod 404 slidably connected to the inner wall of the positioning plate 403, and the surface of the positioning rod 404 engaging with the front end of the dust removal frame 200.

[0020] The aperture of the filter screen 300 near the air inlet of the dust collector 100 is larger than the aperture of the filter screen 300 near the air outlet of the dust collector 100. Using two filters 300 can intercept dust in the gas in sequence.

[0021] It should be noted that a high-frequency infrared carbon-sulfur analyzer typically consists of a high-frequency induction combustion furnace, an infrared detection device, a gas path device, and a control device. The high-frequency infrared carbon-sulfur analyzer model that can be selected is the Steel Research Nake CS-3000G model, which is a relatively mature device with existing technology. The specific model can be selected according to actual needs.

[0022] Install the dust collection box 100 in a suitable position inside the high-frequency infrared carbon and sulfur analyzer using bolts and nuts.

[0023] When it is necessary to test the combustion of ore samples, a certain amount of ore sample is accurately weighed using an electronic balance, placed in a specially made ceramic crucible, and an appropriate amount of flux such as iron or tungsten is added. The crucible containing the sample and flux is placed in the furnace chamber of a high-frequency induction combustion furnace, the furnace lid is closed, the gas circuit device is started, and pure oxygen is introduced into the combustion furnace as a carrier gas and combustion-supporting gas. The high-frequency induction combustion furnace is started, and the alternating magnetic field generated by the high-frequency current causes the sample and flux in the crucible to generate induced eddy currents, rapidly heating them to a high temperature.

[0024] Under high temperature and oxygen conditions, carbon and sulfur elements in the sample undergo a chemical reaction with oxygen. Carbon is oxidized to carbon dioxide, and sulfur is oxidized to sulfur dioxide. The combustion mixture containing carbon dioxide and sulfur dioxide, propelled by an oxygen carrier gas, is transported through a gas path device to a dust collection box 100. Two filters 300 within the dust collection box 100 intercept dust particles in the air. The filtered gas is then transported to the absorption cell of an infrared detection device. Carbon dioxide and sulfur dioxide gas molecules absorb infrared radiation of specific wavelengths, causing a change in infrared intensity. The detector detects this change and converts it into an electrical signal.

[0025] The control software collects and processes the electrical signals output by the detector. Based on the relationship between the degree of infrared absorption and the gas concentration, it calculates the content of carbon dioxide and sulfur dioxide in the gas, and then determines the content of carbon and sulfur elements in the sample. Finally, the analysis results are displayed on the computer screen.

[0026] In this embodiment, when the filter screen 300 inside the dust collection box 100 needs to be cleaned, the high-frequency infrared carbon-sulfur analyzer is not running. Pull the positioning rod 404 away from the dust collection frame 200, rotate the positioning disk 403, and make the two side baffles 401 flip 90 degrees in sequence. Then, the four flipped baffles 401 block the top and bottom of the dust collection frame 200, thereby blocking the filter screen 300. At this time, release the lock of the dust collection frame 200 inside the dust collection box 100, pull the dust collection frame 200 away from the dust collection box 100, and flip the four baffles 401 to rotate 90 degrees to expose the filter screen 300, so that the filter screen 300 can be cleaned.

[0027] like Figure 4As shown, one end of the positioning disk 403 is fixedly connected to a limiting block 406, the inner wall of the positioning rod 404 is slidably connected to the surface of the limiting block 406, the inner wall of the positioning rod 404 is slidably connected to an elastic rod 405, the surface of the elastic rod 405 is engaged with the inner wall of the limiting block 406, the front end of the dust removal frame 200 is fixedly connected to several limiting rods 408, the surface of the positioning disk 403 contacts the surface of one of the limiting rods 408, the end of the positioning rod 404 is fixedly connected to a spring 407, and the other end of the spring 407 is fixedly connected to one end of the positioning disk 403.

[0028] The baffle 401, fixing plate 402, positioning plate 403, and spring 407 are all made of stainless steel with smooth surfaces, reducing the adhesion between dust and the baffle 401 and fixing plate 402. The positioning rod 404 and elastic rod 405 are both made of silicone rubber, which has high temperature resistance and high elasticity.

[0029] In this embodiment, the cleaned dust collection frame 200 is inserted into the dust collection box 100. The positioning disk 403 is rotated, causing the positioning disk 403 to drive the baffle 401 to rotate 90 degrees, so that the positioning disk 403 abuts against one of the limiting rods 408, and one side of the baffle 401 abuts against the fixed plate 402, loosening the restriction on the positioning rod 404. The elastic force of the spring 407 pushes the positioning rod 404 to move laterally on the surface of the limiting block 406 and lock it in the dust collection frame 200. The elastic rod 405 slides into the positioning rod 404 and locks it in the limiting block 406, thereby locking the baffle 401. The other baffles 401 are flipped and locked in the same way, so that the filter screen 300 is exposed in the dust collection box 100.

[0030] like Figure 5 As shown, a screw 409 is threadedly connected to the inner wall of the dust collector 100. The surface of the screw 409 is threadedly connected to the inner wall of the dust collector frame 200. A magnetic ring 410 is fixedly connected to the surface of the screw 409. The dust collector 100 is made of martensitic stainless steel. The bottom end of the magnetic ring 410 is magnetically attracted to the end of the dust collector 100. Nylon ropes 411 are fixedly connected to the top end of the screw 409 and the surface of the elastic rod 405. The other end of one nylon rope 411 is fixedly connected to the end of the dust collector 100, and the other end of the other nylon rope 411 is fixedly connected to the surface of the positioning rod 404. The magnetic ring 410 is a samarium cobalt magnet component, which has high temperature resistance.

[0031] In this embodiment, the screw 409 is threaded into the dust collection box 100 and the dust collection frame 200, so that the magnetic ring 410 is attracted to the end of the dust collection box 100, and the dust collection frame 200 is locked inside the dust collection box 100.

[0032] Working principle: Pulling the elastic rod 405 away from the positioning rod 404, pulling the positioning rod 404 away from the dust collection frame 200, and rotating the positioning disk 403 against one of the limiting rods 408, causing the two side baffles 401 to rotate 90 degrees in sequence, thereby sealing the top and bottom of the dust collection frame 200 and the filter screen 300. At this time, rotating the screw 409 away from the dust collection frame 200, pulling the dust collection frame 200 away from the dust collection box 100, making it difficult for the dust attached to the filter screen 300 to overflow into the dust collection frame 200.

[0033] It should be noted that the dust collector 100, dust collector frame 200, filter screen 300, screw 409 and magnetic ring 410 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
