Abstract
The utility model discloses a negative pressure device for unloading tank cars. A glass fiber reinforced plastic tank is used as a negative pressure tank, and an inlet is arranged on the middle upper position of the negative pressure tank. A wired hose is butted with a hydrochloric acid outlet pipe of a hydrochloric acid tank car, simultaneously an air outlet is arranged on the upmost portion of the negative pressure tank to be butted with an acid mist absorption tower, and an outlet is arranged on the lower portion of the negative pressure tank to be butted with a hydrochloric acid pump. The negative pressure device for unloading the tank cars can effectively avoid leakage during a process of unloading hydrochloric acid and is high in unloading efficiency.
Description
Technical field
The utility model relates to the chemical transport field, is specially a kind of groove tanker vehicle unloading negative pressure device.
Background technology
Traditional hydrochloric acid is unloaded, and is the place of the hydrochloric acid transport trolley being reached slightly high low level transfer groove, by the high-low pressure drop hydrochloric acid in the transfer cask is flow to turn trough in the low level certainly, and is stand-by to hydrochloric acid tank the hydrochloric acid pump in the turn trough in the low level by pump again.
This kind method shortcoming is: the one, and turn trough has bigger acid mist to cause environmental pollution in low level, and the 2nd, careless slightly in unloading the process of hydrochloric acid, turn trough overflows hydrochloric acid easily and causes environmental pollution in the low level.
The utility model content
The technical matters that the utility model solved is to provide a kind of groove tanker vehicle unloading negative pressure device, to solve the shortcoming in the above-mentioned background technology.
Groove tanker vehicle unloading negative pressure device, utilize the glass-felt plastic storage tank of processing outside to make negative-pressure cup, an import is opened in the position in negative-pressure cup, dock with the hydrochloric acid outlet pipe of a wired hose with salt acid tank tank car, open an air discharge port in the negative-pressure cup the top with the acid fog absorption tower butt joint, open an outlet below the negative-pressure cup and dock with the hydrochloric acid pump.
Beneficial effect:The utility model can accomplish that in operating process acid mist does not leak, and needn't worry the negative-pressure cup hydrochloric acid of can emerging, the efficient of unloading simultaneously height.
Description of drawings
Fig. 1 is the scheme drawing of the utility model preferred embodiment.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Groove tanker vehicle unloading negative pressure device referring to Fig. 1, during use, at first start acid fog absorption tower 4, open the emptying valve 7 on the negative-pressure cup 2, open the into admission valve 8 of negative-pressure cup 2, open the hydrochloric acid outlet valve 3 of salt acid tank tank car 1, the air emptying of hydrochloric acid pump 9 to this segment pipe of salt acid tank tank car 1 hydrochloric acid outlet, close the emptying valve 7 of negative-pressure cup 2 then, start hydrochloric acid pump 9, utilize the draft of pump to form negative pressure for negative-pressure cup 2, make hydrochloric acid stream in the salt acid tank tank car 1 to negative-pressure cup 2, and be transported to by negative-pressure cup, in the hydrochloric acid tank 5, treat that the hydrochloric acid of explanation salt acid tank tank car 1 when hydrochloric acid liquid level tube 6 descends in the negative-pressure cup 2 is unsnatched.
More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
