Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses an acid-base protective clothing, including protective clothing body 1, protective clothing body 1 comprises disjunctor trousers 2, jacket 3 and cap 4, and the design of this kind of integral type makes protective clothing have bigger protection area to the human body than ordinary protective clothing. This 1 cap of protective clothing body is equipped with the oblique acid-proof alkali zip fastener 9 of putting of being connected with trousers 2 along the minimum, conveniently dresses, and 1 surface of protective clothing body is provided with the matte 19 that covers zip fastener 9 simultaneously, and this matte 19 covers zip fastener 9 completely, guarantees that the corrosive liquids that splashes can not follow zip fastener 9 and get into in the protective clothing body 1, the length limit and the 1 adhesion of protective clothing body of the top of matte 19. In order to enable an operator to better protect the face part in a complex environment, protective goggles 17 for acid and alkali resistance are adhered on the cap 4, a mask 18 connected with the cap 4 through buttons is arranged below the protective goggles 17, and the cap 4 can completely protect the neck of the operator through a zipper 9. In addition, for the convenience of the collocation use of protective clothing body 1 and protective gloves, protective shoes, the cuff of protective clothing body 1, trouser legs mouth are equipped with elasticity piece 20, and this elasticity piece 20 is the elasticity rope of sewing up at cuff and trouser legs mouth, through cuff, trouser legs mouth that elasticity piece 20 tightened up, wearing protective gloves, protective shoes that operating personnel can be more convenient.

Referring to fig. 3, 4 and 5, the protective clothing body 1 sequentially comprises a waterproof layer 5, an acid-base prevention layer 6, a heat insulation layer 7 and a ventilation layer 8 from outside to inside, wherein the waterproof layer 5 is formed by uniformly coating acrylic waterproof paint on the surface of the acid-base prevention layer 6 and then curing the acrylic waterproof paint, the acid-base prevention layer 6 is made of nylon, the heat insulation layer 7 is made of polyurethane foam plastic and is bonded with the acid-base prevention layer 6, the ventilation layer 8 is made of reticular cotton linen, and the edge of the ventilation layer is bonded with the protective clothing body 1. Waterproof layer 5 has avoided taking place exothermic phenomenon with the acid-base liquid that splashes when being stained with water on the protective clothing body 1, and insulating layer 7 can not scalded when having guaranteed that operating personnel contacts the high temperature medium, and ventilative layer 8 then has the ventilation effect and makes protective clothing body 1 dress more comfortable.

In order to enable the protective clothing body 1 to have good air permeability on the basis of having the acid and alkali resistance and other functions, a plurality of acid and alkali resistance vent pipes 10 which are uniformly distributed are embedded in the back of the protective clothing body 1, and the vent pipes 10 are connected with the acid and alkali resistance adhesive which can be used by the protective clothing body 1. The ventilation pipe 10 is formed by sequentially connecting an air inlet section 101, a liquid discharge section 102 and an air outlet section 103, wherein the air inlet section 101 is positioned between the ventilation layer 8 and the heat insulation layer 7, the air outlet section 103 extends out of the waterproof layer 5, and sweat generated by a human body is evaporated and then is discharged out of clothes from the air outlet section 103. In order to prevent splashed corrosive liquid from entering the protective suit body 1 along the vent pipe 10, the position of the pipe orifice of the air inlet section 101 is higher than that of the pipe orifice of the air outlet section 103. Because the section 103 of giving vent to anger is located outside the waterproof layer 5 of protective clothing body 1 and influences pleasing to the eye, can cover acid-proof alkaline cover cloth 13 (refer to fig. 2) on the section 103 of giving vent to anger of permeability cell 10, the higher authority of cover cloth 13 bonds with protective clothing body 1, and this design not only makes protective clothing body 1 pleasing to the eye and has avoided the acid-base liquid that splashes to permeate protective clothing body 1 along permeability cell 10 and clothes junction.

In order to further increase the air inlet area of the pipe orifice of the air inlet section 101, improve the air permeability of the ventilation pipe 10 and ensure comfortable wearing, an air inlet disc 11 is arranged on the pipe orifice of the air inlet section 101, the air inlet disc 11 is funnel-shaped, the mouth of the air inlet disc is in adhesive connection with the pipe orifice of the air inlet section 101, and the disc mouth of the air inlet disc 11 is also bonded with the ventilation layer 8. The vapor that human sweat formed probably liquefies into the drop of water in permeability cell 10, causes the hydrops in the permeability cell 10, consequently, places flowing back section 102 downwards along the orientation slope of ventilative layer 8 to waterproof layer 5 to set up along vertical direction and make its mouth of pipe down with section 103 of giving vent to anger, guarantee that the hydrops can follow and flow in the permeability cell 10. The acid and the alkali are volatile, and gas possibly formed enters the protective clothing body 1 along the vent pipe 10, so that the middle part of the liquid discharge section 102 is connected with the one-way air valve 12 in a sticking mode, the one-way air valve 12 limits the gas to flow to the air outlet section 103 from the air inlet section 101, the fact that the sweat of a human body can enter the atmosphere through the one-way air valve 12 after being evaporated is guaranteed, and the external acid and alkali volatile gas cannot enter the protective clothing body 1.

Referring to fig. 2 and 6, in order to further accelerate the circulation of the gas inside and outside the protective clothing body 1, the permeability of the protective clothing body 1 is enhanced. There are two symmetrical acid-proof and alkali-proof ventilative section of thick bamboo 14 at the back veneer of protective clothing body 1, this ventilative section of thick bamboo 14 protrusion in the surface of protective clothing body 1 to there is an air suction fan 15 from the electrified source at ventilative section of thick bamboo 14 female connection, and this air suction fan 15 can connect the charging wire and charge. The air suction fan 15 is turned on, and outside air is sucked into the protective clothing body 1 and is discharged through the vent pipe 10, so that the air permeability of the protective clothing body 1 can be greatly improved. In order to avoid that the toxic gas is sucked into the protective suit body 1 by the suction fan 15 in the process of sucking the gas, a gas inlet end of the ventilation cylinder 14 is stuck with a gas filtering layer 16 for filtering the toxic gas, and the gas filtering layer 16 can directly use a 3M gas filtering box for a protective mask and can also be made of other materials with similar functions.

The implementation principle of the embodiment is as follows: when using the protective clothing, the operator unzips the zipper 9 of the protective clothing body 1 to wear the protective clothing, zips the zipper 9 after wearing the protective clothing, covers the zipper 9 with the edge covering 19, and wears the cap 4 and the mask 18 as required. After the protective clothing is worn, the switch of the air suction fan 15 is turned on, external fresh air is sucked into the protective clothing body 1, and harmful gas mixed in the air is filtered outside the protective clothing body 1 by the filter layer. The air entering the protective clothing body 1 and the sweat evaporated by the human body enter the ventilating pipe 10 together and are discharged out of the protective clothing body 1 from the air outlet section 103. The suction fan 15 is periodically charged according to the use condition.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
