Abstract
The utility model provides an electric dustproof mask which belongs to the technical field of labour protective articles. A battery and a transformer are used for providing high voltage direct current which is applied to a positive and a negative electrodes which are arranged in a dust removing box to form a high voltage electric field. Electrostatic force produced by the high voltage electric field makes dust particles charge current which is separated from airflow. The utility model has the advantages of high dust removing efficiency, small air inhalation resistance and comfortable wearing. The utility model still has high removing efficiency to power dust which is smaller than 1 micrometre.
Description
The utility model relates to a kind of anti-dust respirator, belongs to the appliances for labor protection technical field.
For some industry such as cement, mine industry, dustproof is an important labour protection task.The dustproof employing of individual worn anti-dust respirator at present, the not smooth shortcoming of existing Filter film type anti-dust respirator ubiquity ventilation; Recently disclosed ZL97218620.4 patent adopts Wet technique, to a certain degree might alleviate the problems referred to above, but for reaching the effect of removing fine dusts, sucking gas still need have fair speed at the dedusting position, so the big problem of inspiratory resistance is still solved at the end at all.
The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of good purification and inspiratory resistance little Electric dust-proof mouth mask.
The purpose of this utility model is achieved in that the utility model is made up of mouth mask (1) and dedusting box (2) two parts, is connected by flexible pipe (3) between them.Wherein the mouth mask part is same as the prior art.The dedusting function of dedusting box is realized by following manner: provide high voltage direct current by high-voltage DC power supply (not drawing among the figure), put on metallic plate (6) and the metal wire (7), make it to become positive and negative electrode, and form high voltage electric field betwixt; Ionization takes place in gas under this effect of electric field; Dust is charged when the dust-contained airflow that sucks passes through this electric field; Dust after charged moves to electrode, loses electric charge behind the arrival electrode, becomes neutrality and heavy the collection on its surface, thereby reaches the purpose of dedusting.Experiment confirm, high more by the low more then efficiency of dust collection of air velocity of electric field, so adopt low air velocity in the dedusting box.
The utility model makes dust granules charged because of the electrostatic force that adopts high voltage electric field to produce, and separates from air-flow, so the efficiency of dust collection height still has very high removal efficiency for the dust below 1 micron; Because adopt air velocity in the low dedusting box,, wear comfortable so resistance is little.
Concrete structure of the present utility model and operation principle are provided in detail by following embodiment and accompanying drawing thereof.
Fig. 1 is the overall structure outline drawing according to the Electric dust-proof mouth mask that the utility model proposes.
Fig. 2 just (cuts open) view according to dedusting box (2) in the Electric dust-proof mouth mask that the utility model proposes.
Describe details and working condition in detail below in conjunction with Fig. 1 and Fig. 2 according to the concrete device that the utility model proposes.
The utility model is made up of mouth mask (1) and dedusting box (2) two parts, and they are connected by flexible pipe (3).Wherein the mouth mask part is same as the prior art.The mouth mask both side surface has exhaling hole (9), and the central authorities below has inlet hole (10), respectively embedded unidirectional film flap valve.Dedusting box (2) is the casing that an insulating materials is made, its bottom has air admission hole (4), the top has venthole (5) and links to each other with flexible pipe (3), the left and right sides inwall is embedded with two metallic plates that are arranged in parallel (6) respectively, parallel, one group of metal wire of spaced set (7) in the middle of two parallel metal sheets (6).Metallic plate (6) and metal wire (7) respectively with the positive and negative electrode of a high-voltage DC power supply (not drawing among the figure) by lead be connected (not drawing among the figure); Metallic plate (6) and metal wire (7) also can be respectively with the negative, positive utmost point of a high-voltage DC power supply by lead be connected (not drawing among the figure).High-voltage DC power supply can be made of battery (not drawing among the figure) and transformer (not drawing among the figure), and wherein battery provides electric power, and transformer then brings the voltage up to 3-30kv.Turn on the power switch during use,, form high voltage electric field therebetween so metallic plate (6) and metal wire (7) become positive and negative electrode.Ionization takes place in gas under this effect of electric field; The dust-contained airflow that sucks by air admission hole (4) during by this electric field dust charged; Dust after charged moves to electrode, loses electric charge behind the arrival electrode, becomes neutrality and heavy the collection at electrode surface, thereby reaches the purpose of dedusting.Powered-down switch then when stopping using.
Through experiment confirm, this anti-dust respirator efficiency of dust collection height, resistance is little, wears comfortable.
