Description
(1) technical field
The present invention relates to a kind of occupational disease safety device, particularly relate to a kind of wear-type and prevent the protector that anthraco-silicosis is used in advance.
(2) background technology
China is in nearly 20 years reform and opening-up process, and economic development has obtained achievement attracting people's attention, and when economy obtained rapid development, the change of matter was also taking place Chinese people's quality of life, has enough to eat and wear from the satisfied of past, to paying attention to quality of life and health.The important foundation that provides people to live basic guarantee is provided in work, and the quality of condition of work also has influence on everyone health and safety.But found the state over more than 50 year, the occupational disease of China record is high always, makes great efforts to become in the process of World Economics big country at us always, is but still keeping the record of leading in the world anthraco-silicosis big country always.Because the various health risk pollutants that exist in the operation place; the primary approach of infringement human body is respiratory system (accounting for 90%); so individual protection aspect at respiratory system; be necessary to explore the personal breathing protective gear of some science; protection labourer's health and safety, the rate occurred frequently of minimizing occupational disease.Anthraco-silicosis not only threatens professional workman's life and health, returns national economy and causes tremendous loss.
From preclinical medicine science aspect it can be asserted that; anthraco-silicosis can not be effected a radical cure; unique way of protection workers ' health is contacting with control workman and dust; improving working environment with advanced person's dust-settling technology is best bet; in view of current very big with dust-settling technology change entire environment difficulty; develop state-of-the-art personal protective equipment with advanced person's science and technology, one of the good means of prevention of also can yet be regarded as.Because it is personnel's protection is the most important, the most direct, also extensive.
For these years, China adopts cotton cloth respirator mostly aspect respiratory protection, and the dust proof rate of cotton cloth respirator generally connect 30% less than, do not have dustproof effect at all, use cotton cloth respirator just China keep a major reason of anthraco-silicosis big country title always.In recent years, China forbids to use cotton cloth respirator as anti-dust respirator, and some enterprise adopts the high relatively compound anti-dust respirator of some dust proof rates, anti-particulate mouth mask of filtering type and mask etc., though compare, can't but be a very big progress, but have some particular problems with cotton cloth respirator.Such as, these filtering type dust masks, mouth mask etc., to say objectively all can not with people's the complete driving fit of face, nose, fine solid particle creeps into mouth mask by the not tight slit of driving fit probably, and enter people's lung, moreover, heavy physical labour especially at work, expiratory dyspnea, seal very, influence operating efficiency greatly, some people just gives it up, and health is subjected to very big injury.As seen traditional protective respirator, the defective of various degrees awaits innovation.
(3) summary of the invention
The technical problem to be solved in the present invention is to provide having of a kind of body and function good dustproof effect at the problems referred to above, can reduce significantly because of breathing the positive-pressure type protector of respiration that dust and pernicious gas are suffered from diseases such as lung.
The technical scheme that adopts is:
The positive-pressure type protector of respiration comprises safety cap and dust guard.
Dust guard comprises dirt catcher, air-introduced machine, appendix, protective acoustic cover assembly and power supply.
Dirt catcher and air-introduced machine are installed in the same shell body, and air-introduced machine is positioned at the front portion of dirt catcher.Air-introduced machine is by DC power supply.Air inlet and gas outlet are arranged on the shell body.
Protective acoustic cover assembly comprises protective cover, protective cover clip, face shield and two spring pull bars.OFP side periphery and protective cover frame inner peripheral are moulded by mill and are fitted, or connect by double buckle, and the face shield inner peripheral is a structural elastic, and face shield is made with costive, as waterproof cloth, airtight fire retardant etc., passage is arranged on the face shield.The outer rim shape of protective cover clip and protective cover upper ledge inner edge shape adapt, and coupling contact mutually, and the anterior shade shape of protective cover clip inner edge shape and safety cap is complementary, and fluted.The forward position of safety cap and protective cover clip are pegged graft.Protection is covered with form, and the upper end, both sides of protective cover connects by bearing pin and safety cap respectively or connects by lock shaft and protective cover clip.Protective cover can on turn over, the shell body that dirt catcher and air-introduced machine are housed is fixed on the safety cap.Two spring pull bars are separately positioned on two sides of safety cap, one end of spring pull bar is fixedlyed connected with shell body, the other end is fixed on the rear end of head protector clip, and an end of appendix is connected with the air outlet on the shell body, and the other end is connected with the air inlet of clip.
Above-mentioned appendix is a bellows, is convenient to regulate length.
Above-mentioned safety cap both sides are installed with rope band respectively, when the safety hatband is on head, fasten rope band, do not come off to guarantee safety cap.
The medium of above-mentioned dirt catcher can be selected active carbon particle, medical stone granule: for use, or materials such as nonwoven, carbon fiber, also can be that nonwoven combines with carbon fiber or nonwoven combines with active carbon particle.
During use safety cap is worn on the head, has tied rope band, make protective cover frame and people's facial driving fit.Connect power supply, air-introduced machine work, the noxious air of band dust enters dirt catcher from the air inlet on the housing, the airborne harmful dust of filtering, pure air after the purification is breathed usefulness for the staff in appendix is sent into protective cover, the interior unnecessary gas of carbon dioxide that spues after the breathing and input protective cover is discharged from the passage on the face shield, promptly keeps being malleation in the protective cover, guarantees that the pernicious gas of the band dust in the working environment can not enter in the protective cover.
The present invention is simple in structure, cost is low, good dustproof effect, can guarantee that the worker who works in the working environment of dust from flying is arranged can not suffer from anthraco-silicosis because of inhaling dust.
