Activated carbon harmful gas filter box with silencing structure

Abstract

The invention discloses an activated carbon harmful gas filter box with a silencing structure. The filter box comprises a filter box body, wherein a mounting groove is formed in the inner wall of thetop of the filter box body; a stepping motor is mounted in the mounting groove; a first rotating shaft is welded to the output shaft of the stepping motor; cross plates are welded to the inner walls on two sides of the filter box body; vertical plates are welded to the sides close to each other, of the two cross plates; the first rotating shaft is located between the two vertical plates; a same movable plate is slidably mounted on the sides close to each other of the two vertical plates; a threaded hole is formed in the top of the movable plate; an outer thread is arranged on the outer side ofthe first rotating shaft; and the outer thread on the first rotating shaft is in threaded connection to the threaded hole. The filter box disclosed by the invention is high in practicality. A filterscreen can be effectively prevented from being blocked in a process of moving up and down repeatedly through the first rotating shaft and a first magnet; the eliminating efficiency of inhalable particles can be improved effectively through wire drawing and a second spring.

Description

technical field [0001] The invention relates to the technical field of filter boxes, in particular to an activated carbon-type harmful gas filter box with a noise reduction structure. Background technique [0002] In recent years, air pollution has become more and more serious. The world index is that PM2.5 (inhalable particulate matter with a diameter of ≤2.5 microns) is less than 10, which is a safe value, but in most parts of our country, it is higher than 50. The air quality is not good, which seriously affects human health. Therefore, it is necessary to effectively filter and sterilize the outdoor air entering the room, and purify the air to protect the health of the human body. The current filter box is basically noiseless when it works. After retrieval, the application publication number is a kind of air disclosed by CN103245010A. A device for filtering and sterilizing to eliminate harmful gases, including a box body and filters arranged side by side in the box, plate...

[0002] In recent years, air pollution has become more and more serious. The world index is that PM2.5 (inhalable particulate matter with a diameter of ≤2.5 microns) is less than 10, which is a safe value, but in most parts of our country, it is higher than 50. The air quality is not good, which seriously affects human health. Therefore, it is necessary to effectively filter and sterilize the outdoor air entering the room, and purify the air to protect the health of the human body. The current filter box is basically noiseless when it works. After retrieval, the application publication number is a kind of air disclosed by CN103245010A. A device for filtering and sterilizing to eliminate harmful gases, including a box body and filters arranged side by side in the box, plate-type low-temperature plasma, ozone filter and fan device, the fan device is used to suck air into the box and pass through the filter, plate-type The low-temperature plasma and ozone filter are used to blow out the air, and the fan device sucks the air into the box and blows it out after treatment, and processes the inhalable particles and harmful gases in the air entering the box. By controlling the motor speed, the air is cleaned The air volume of the treatment is steplessly adjusted, which greatly expands the application range of air filtration and sterilization, reduces the energy consumption of the device, and can eliminate harmful gases in the air, so that the concentration of harmful gases in the air is controlled within the national standard range, but its The filter inside the filter is prone to clogging, and its efficiency in removing inhalable particulate matter is low, so we propose an activated carbon-type harmful gas filter box with a sound-absorbing structure to solve the above problems
