Formaldehyde removal device capable of self-adjusting the purification speed

Abstract

The invention discloses a formaldehyde removal device capable of self-adjusting the purification speed. The formaldehyde removal device comprises a removal housing, wherein a working cavity is formedin the removal housing; a removal pipeline is fixedly arranged in the working cavity; the left end of the removal pipeline extends leftwards into a room; the right end of the removal pipeline extendsrightwards to the outside; a formaldehyde removal assembly is arranged in the removal cavity; and an adjusting assembly is further arranged in the working cavity. According to the formaldehyde removaldevice, a fan is adopted, and air containing formaldehyde in the room can be discharged outdoors after being filtered by an activated carbon filter screen through wind power generated by the fan; a fixed friction wheel and an adjusting friction wheel are adopted, and the adjusting friction wheel can be in friction connection with different radiuses of the fixed friction wheel according to different concentrations of formaldehyde in the room, so that the rotating speed of the fan is changed; and an alarm assembly is adopted, and when an auxiliary coupler is connected with a main coupler in a matched mode, a sound bell can rotate and make a sound to remind workers of too high concentration of formaldehyde in the room in time to pay attention to protection.

Description

technical field [0001] The invention relates to the technical field of formaldehyde removal equipment, in particular to a formaldehyde removal device capable of self-adjusting purification speed. Background technique [0002] Formaldehyde is a colorless gas that is irritating to human eyes and nose. At present, the International Agency for Research on Cancer of the World Health Organization has placed formaldehyde in the list of a class of carcinogens in the published list of carcinogens, so it has certain safety hazards for long-time spray paint workers. However, in the general painting work area at present, the formaldehyde removal method is simply adopted by opening windows for ventilation. In the case of no wind, indoor formaldehyde cannot be removed well, and when the concentration of formaldehyde is too high, it is impossible to warn in time. Worker, a kind of device that the present invention illustrates can solve the above-mentioned problem. Contents of the invent...
