Abstract
The utility model discloses a liquid hazardous articles tank car system of unloading of easy crystallization has a jar body and extends the pipeline of unloading of jar interior bottom, is equipped with the discharge valve on the discharge line, still including following the top seal of jar body extends the air inlet pipeline of jar interior top, and air inlet pipeline even has the air compressor machine, and the air inlet valve still is equipped with on the air inlet pipeline. Adopt the liquid hazardous articles tank car system of unloading of easy crystallization of above-mentioned structure, unload through upper portion pressure, changed traditional mode of unloading, the material does not pass through the pump, can not cause the pump to block up, and the pipeline of unloading is swept through the gas, can not cause and remain, solves the jam influence that the crystallization caused.
Description
Technical Field
The utility model relates to a liquid hazardous articles tank car system of unloading, specifically speaking relate to an easy liquid hazardous articles tank car system of unloading of crystallization.
Background
The traditional liquid dangerous goods tank car adopts the bottom unloading mode to unload, and liquid materials are unloaded through the tank bottom pipeline, the valve and the pump, so that the tank is convenient, fast, safe and reliable. However, the materials contained in the tank car for the easily crystallized liquid dangerous goods can be crystallized at normal temperature, and the unloading mode is not suitable for the unloading operation of the tank car for the easily crystallized liquid dangerous goods. For example, liquid caustic soda belongs to easily-crystallized liquid dangerous goods, the liquid caustic soda begins to crystallize at about 10 ℃, general liquid caustic soda is loaded into a tank truck under the condition of higher temperature, is in liquid transportation under the condition of heat preservation or self-heat storage, the liquid remains after unloading, the liquid enters the crystallization state after the temperature is reduced to cause the blockage of a pipeline, a valve and a pump, the pipeline, the valve and the pump can not normally work when being reused, in order to ensure the normal use of the pipeline and the valve, an operator can often adopt the modes of field heating and the like to solve the problem, but the mode can relieve certain problems when the temperature is higher, the time and labor are wasted when the problem is solved in winter, the effect is still not good, meanwhile, alkali liquor easily hurts people, and great inconvenience is caused to transportation and production and operation.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the above-mentioned not enough, provide an easy liquid hazardous articles tank car system of unloading of crystallization, use the utility model discloses the operation of unloading that can be applicable to easy liquid hazardous articles tank car of crystallization betterly afterwards.
In order to solve the technical problem, the utility model relates to an easy liquid hazardous articles tank car system of unloading of crystallization has the jar body and extends the pipeline of unloading of jar bottom in, is equipped with discharge valve, its characterized in that on the discharge line: still including following the top of jar body is sealed extends the air inlet pipeline of jar interior top, and the air inlet pipeline even has the air compressor machine, still is equipped with the admission valve on the air inlet pipeline.
As the improvement of the utility model, be located the relief valve still is equipped with on the intake manifold line between air compressor machine and the admission valve.
As a further improvement, the utility model also comprises a follow the top seal of the tank body extends to the exhaust pipe line of the upper portion in the tank, and exhaust valve is equipped with on the exhaust pipe line.
As another improvement of the utility model, the bottom of the tank body is formed with a sunken reservoir, and the discharge pipeline extends into the reservoir.
The liquid hazardous articles tank car system of unloading of easy crystallization of adopting above-mentioned structure unloads through upper portion pressure, has changed traditional mode of unloading, and the material does not pass through the pump, can not cause the pump to block up, and the pipeline of unloading is swept through the gas, can not cause and remain, solves the jam influence that the crystallization caused.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural composition diagram of the discharging system of the liquid dangerous goods tank car easy to crystallize.
Detailed Description
Referring to fig. 1, the utility model relates to an easy liquid hazardous articles tank car system of unloading of crystallization has jar body 1 and extends jar interior bottom discharge line 2, is equipped with discharge valve 3 on the discharge line, its characterized in that: the tank is characterized by further comprising an air inlet pipeline 4 extending from the top of the tank body 1 to the upper part in the tank in a sealing manner, wherein the air inlet pipeline is connected with an air compressor 5, and an air inlet valve 6 is further arranged on the air inlet pipeline. And a safety valve 7 is also arranged on an air inlet pipeline between the air compressor 5 and the air inlet valve 6. The device also comprises an exhaust pipeline 8 which extends from the top of the tank body 1 to the upper part in the tank in a sealing way, and an exhaust valve 9 is arranged on the exhaust pipeline. A concave liquid storage tank 10 is formed at the bottom of the tank body 1, and the discharge pipeline 2 extends into the liquid storage tank.
The utility model discloses in, air compressor machine 5 squeezes into jar body 1 with compressed air through air inlet pipeline 4 in, makes jar interior formation malleation, impresses jar interior liquid through the malleation pipeline 2 of unloading and realizes unloading. The safety valve 7 controls the pressure value of the pipeline and the system, and the exhaust is immediately started when the pressure value exceeds a limit value. After the unloading is finished, the pressure air of the air compressor continues to enter the tank, residual liquid in the unloading pipeline can be swept completely, and then the unloading valve 3 is closed. Before charging, the exhaust valve 9 on the primary exhaust pipeline 8 is opened to exhaust redundant air in the tank, so that the balance of pressure inside and outside the tank is realized, and the gas explosion caused by opening the tank cover in a pressure state is avoided. The discharging pipeline extends into the liquid storage tank 10 with the concave bottom of the tank body 1, so that the liquid in the tank can be discharged more cleanly and thoroughly when the discharging is carried out, and even if a small amount of residual liquid in the liquid storage tank is crystallized, the liquid can be dissolved by the temperature of newly-loaded materials when the materials are loaded again.
