Background
In the prior art, when hydrochloric acid is taken from a hydrochloric acid tank body through a manual valve in a workshop, no protection is provided at an outlet, liquid drops of the hydrochloric acid can splash onto equipment and an operation table of the workshop and are accompanied by high-concentration hydrochloric acid smog, the liquid drops splash to cause severe corrosion, workers can be exposed to the smog to cause acute poisoning, the phenomena of eye conjunctivitis, burning sensation of nasal cavities and oral mucosa and the like occur, and chronic rhinitis, chronic bronchitis, tooth acidosis and skin damage are easily caused by long-term exposure.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above insufficiency and provide a prevent corrosive liquid splash and the protection device of getting hydrochloric acid of improving the environment is got in work.
The technical solution of the utility model is that: a protective device for receiving hydrochloric acid is characterized by comprising a box body, wherein a vertical hinged door is arranged on one side of the box body, a hydrochloric acid pipeline outlet of a hydrochloric acid tank body penetrates through a top plate of the box body and a layer of partition plate with holes below the top plate, and a small disc filled with a material for adsorbing hydrochloric acid mist is placed on the partition plate with holes; a clapboard with a hole is arranged above the inner bottom of the box body, and a big hole is arranged at the outlet which is opposite to the hydrochloric acid pipeline; an edge with a certain height is added in the direction parallel to the vertical hinged door on the lower bottom plate of the box body, and the edge and the lower bottom plate form an inner groove for containing a low-concentration sodium hydroxide solution tank.
In the above-mentioned scheme, the first step of the method,
the vertical hinged door is connected with the box body in a magnet adsorption mode.
The diameter of the large hole is 7 cm.
The height of the edge is 1 cm.
The utility model has the advantages that: 1. the hydrochloric acid outlet is connected to the hydrochloric acid tank body, the protective device is arranged at the hydrochloric acid outlet, so that corrosive liquid can be effectively prevented from splashing to the periphery, the volatile gas is reduced from diffusing to the surrounding environment, the protection of the hydrochloric acid during manual connection and taking is increased, the damage of the hydrochloric acid to the surrounding environment is reduced, and the protective device can effectively protect personnel. 2. The porous partition board is provided with a small disc made of PP or PE material, and the small disc is filled with an adsorbent substance (active carbon) or a neutral solution (low-concentration sodium hydroxide solution with the concentration of 0.05-0.1M) for adsorbing hydrochloric acid mist, so that the harm of the hydrochloric acid mist is reduced. The lower perforated partition plate and the upper large holes of the lower perforated partition plate are arranged, so that the hydrochloric acid dripped from the outlet of the pipeline cannot fall onto the lower perforated partition plate, the bottom of the lower perforated partition plate cannot be stained with the solution when the measuring cup is placed, and the hydrochloric acid liquid is prevented from dripping onto the ground when the measuring cup is moved out of the device. Set up the border, this border constitutes the recess with lower floor's bottom plate, and the sodium hydroxide solution of splendid attire low concentration is used for the neutralization to drip into hydrochloric acid solution.
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Drawings
Fig. 1 is a schematic view of the structure of the present invention.
Detailed Description
Referring to fig. 1, the part names are as follows: the device comprises a partition board 1 with holes, a partition board 2 with lower holes, a box body 3, a vertical hinged door 4, a hydrochloric acid pipeline 5, a box body top plate 6, a large hole 7 and an edge 8.
Referring to fig. 1, a protective device for receiving hydrochloric acid comprises a box body 3, wherein a vertical hinged door 4 is arranged on one side of the box body 3, a hydrochloric acid pipeline 5 outlet of a hydrochloric acid tank body penetrates through a box body top plate 6 and a layer of perforated partition plate 1 below, and a small disc filled with a material for adsorbing hydrochloric acid mist is placed on the perforated partition plate 1; a lower perforated partition plate 2 is arranged above the inner bottom of the box body 3, and a large hole 7 with the diameter of 7cm is arranged at an outlet which is opposite to a hydrochloric acid pipeline; the lower bottom plate of the box body 3 and the direction parallel to the vertical hinged door 4 are additionally provided with an edge 8 with the height of 1cm, and the edge 8 and the lower bottom plate form an inner groove for containing a low-concentration sodium hydroxide solution tank. The vertical hinged door 4 is connected with the box body 3 in a magnet adsorption mode.
Referring to fig. 1, a protective device for receiving hydrochloric acid is a closed acrylic (acrylic plastic) box body 3 with a vertical hinged door on one side, the vertical hinged door 4 is connected with the box body 3 in a magnet adsorption mode, an outlet of a hydrochloric acid pipeline 5 connected with a tank body (hydrochloric acid concentration is 2M) filled with hydrochloric acid penetrates through a top plate 6 of the device and a layer of perforated partition plate 1 below the top plate, a distance of 4-5cm is reserved between the perforated partition plate 1 and the top plate 6 of the device, and when the hydrochloric acid pipeline 5 penetrates through the two layers of plates, a gap as small as possible needs to be ensured, and a raw material belt is used for sealing.
