Description

Technical Field

[0001] The utility model relates to the technical field of rare earth polishing powder processing, in particular to an exhaust gas filtering device for rare earth polishing powder processing. Background Art

[0002] Rare earth polishing powder refers to a powder of mixed light rare earth oxides with cerium oxide as the main component, which is used to improve the surface finish of products or parts. It is usually made of fluorocarbon cerium ore concentrate or soluble rare earth salts as raw materials, and is made through chemical treatment, burning, crushing, screening and other processes. Rare earth polishing powder is prone to produce more waste gas during processing. The waste gas mainly contains sulfur dioxide, nitrogen oxides, and hydrocarbons. In the process of processing rare earth polishing powder, it is necessary to filter the waste gas. When filtering the waste gas, it is necessary to use a waste gas filtering device for rare earth polishing powder processing. Among them, the "waste gas filtering device" disclosed in the announcement number "CN207928921U" has solved the problem of exhaust gas polluting the air. After further searching, it was found that the "a kind of exhaust gas filtering device" disclosed by the announcement number "CN206391833U" has effectively solved the technical disadvantages of strong odor of the discharged exhaust gas, serious pollution of the environment and impact on human health through a specific technical structure setting. However, in actual use, the exhaust gas filtering device with a similar structure for rare earth polishing powder processing still has many defects, such as: the usual exhaust gas filtering device is not convenient for disturbing the filtered exhaust gas, so that the exhaust gas filtering effect is relatively general, and it is not convenient to intercept and collect large particles of impurities in the exhaust gas, so that the large particles of impurities can easily cause clogging of the filtering device, so it is necessary to design an exhaust gas filtering device for rare earth polishing powder processing. Utility Model Content

[0003] The utility model aims to provide an exhaust gas filtering device for rare earth polishing powder processing to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an exhaust gas filtering device for rare earth polishing powder processing, comprising a box body, a filter frame and a movable frame, the filter frame is slidably installed on the inner side of the box body, the inner side of the box body at the bottom of the filter frame is slidably connected to a collecting bucket, a spoiler is fixedly installed inside the box body on one side of the filter frame, a movable frame is slidably installed inside the box body on one side of the spoiler, activated carbon is fixedly installed on the inner side of the movable frame, and a fan is fixedly connected to one side of the box body.

[0005] The waste gas generated during the processing of rare earth polishing powder mainly includes sulfur dioxide, nitrogen oxides and hydrocarbons. Sulfur dioxide, nitrogen oxides and hydrocarbons can be adsorbed by activated carbon. Starting the fan can extract the air in the box, generate negative pressure in the box, and suck the waste gas into the box. The large particles of impurities in the waste gas can be intercepted by the filter frame, so that the large particles of impurities fall into the collection bucket for collection, so as to avoid the blockage of activated carbon by large particles of impurities. The collected large particles of impurities can be centrally cleaned by pulling out the collection bucket. The guide frame can be used to guide the waste gas to the outside so that the waste gas contacts the spoiler. The spoiler can be used to disrupt the waste gas so that the waste gas can fully contact the activated carbon when passing through the activated carbon, so as to improve the filtering effect and facilitate the filtering of the waste gas generated during the processing of rare earth polishing powder. The activated carbon can be easily cleaned or replaced by pulling the movable frame to move upward synchronously and extend out of the box.

[0006] Preferably, a butt joint is fixedly mounted on one side of the box, and a flange is fixedly connected to one end of the butt joint. The flange can be conveniently connected to the exhaust gas discharge pipe of the rare earth polishing powder processing device, so that the exhaust gas discharge pipe of the rare earth polishing powder processing device can transport the exhaust gas generated during the rare earth polishing powder processing into the butt joint, and then transport the exhaust gas into the box.

[0007] Preferably, the filter frame is slidably mounted on the box body via a sliding frame, and the front end of the filter frame extends out of the box body. The sliding frame can be conveniently used to limit the filter frame and can slide the sliding frame to make the filter frame at an inclined angle, so that the filter frame can be easily pulled forward for cleaning.

[0008] Preferably, the movable frame and the box body are slidably mounted via a limit bar, and a support pad is fixedly mounted on the bottom of the box body. The limit bar allows the movable frame to slide up and down to prevent the movable frame from tilting when sliding up and down, and the support pad can support the box body and play an anti-slip role.

[0009] Preferably, a fixing plate is fixedly installed on the top of the movable frame, and the fixing plate and the box body are fixed by a fixing knob. By turning the fixing knob, the fixing plate can be fixed on the top of the box body, and the movable frame is supported and fixed simultaneously. By turning the fixing knob in the opposite direction, the movable frame can be easily pulled upward.

[0010] Preferably, a handle is fixedly mounted on the top of the movable frame, and a guide frame is fixedly connected to one side of the spoiler. By pulling the handle up and down, the movable frame can be driven to move up and down synchronously, and the exhaust gas can be guided outward through the guide frame so that the exhaust gas contacts the spoiler.

[0011] Preferably, the air intake end of the fan is connected to the box through an air intake pipe, and an air outlet pipe is fixedly installed on the air outlet end of the fan. The air intake pipe can be used to allow the fan to suck out the air in the box, and the air sucked out can be discharged through the air outlet pipe, so that negative pressure is generated in the box.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By setting up the mutual cooperation between the spoiler, the movable frame and the activated carbon, the exhaust gas is allowed to enter the box, and the exhaust gas can be filtered by the activated carbon, which can facilitate the filtering operation of the exhaust gas generated during the processing of rare earth polishing powder. The spoiler can be used to disrupt the airflow of the exhaust gas entering the box, so that the exhaust gas can fully contact with the activated carbon when passing through the activated carbon, which can improve the filtering effect. By pulling the movable frame upward and extending out of the box, the activated carbon can be easily cleaned or replaced.

[0014] 2. By setting up the cooperation between the box, the filter frame and the collection bucket, when the exhaust gas enters the box, the filter frame can intercept the large particles of impurities in the exhaust gas, so that the large particles of impurities fall into the collection bucket for collection, avoiding the situation where the large particles of impurities cause blockage of the activated carbon. By pulling out the collection bucket, the collected large particles of impurities can be cleaned up in a centralized manner. BRIEF DESCRIPTION OF THE DRAWINGS
