Description
Technical Field
The utility model relates to the technical field of chemical equipment, in particular to a safe centrifugal pump unloading device.
Background
At present, most raw materials in the chemical industry are transported by tank trucks, and during the unloading process of the tank trucks, the tank trucks are mostly unloaded by adopting a manual visual method or a quantitative unloading method. In the former, because the unloading pipeline is very short, the pump stopping time cannot be accurately controlled, personnel frequently go up and down the tank car, potential safety hazards exist, and the personnel have falling risks in the process of going up and down the tank car; in the latter case, the internal flow volume of the tank car and the set value of the quantitative unloading car can not be completely consistent, so that the phenomenon of incomplete unloading or evacuation of the centrifugal pump can occur during unloading, and the centrifugal pump is damaged. Although the interlock protection pump is provided, the pump is idle due to the limited material in the pipeline and evacuation after the interlock shutdown, and the idle of the pump may cause direct damage to accessories such as a centrifugal pump seal and the like, so that the service life of the centrifugal pump is shortened, safety accidents are caused, and the protection effect is not ideal.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problems, the utility model is realized by the following technical scheme:
a safe centrifugal pump unloading device comprises a material buffer tank, wherein a liquid level meter is arranged on the material buffer tank, an unloading pipeline is connected to the upper portion of the material buffer tank, a feed valve and a flange are sequentially arranged on the unloading pipeline from right to left, and the unloading pipeline is connected with an unloading crane pipe through the flange; the centrifugal pump is characterized in that the bottom of the material buffer tank is connected with a centrifugal pump through a material pipeline I, a centrifugal pump inlet valve is arranged at the position, close to the centrifugal pump, on the material pipeline I, the centrifugal pump is connected with a material receiving tank through a material pipeline II, and a centrifugal pump outlet valve is arranged at the position, close to the centrifugal pump, on the material pipeline II.
Preferably, a pressure gauge is arranged between the centrifugal pump and the outlet valve of the centrifugal pump.
Preferably, the unloading arm is connected with the tank truck.
Compared with the prior art, the utility model has the beneficial effects that: by arranging the material buffer tank, a field operator can stop the pump in time according to the liquid level change in the material buffer tank. The phenomenon that the centrifugal pump is damaged due to idling of the centrifugal pump is avoided, manual operation is reduced, working efficiency is improved, the service life of the centrifugal pump is prolonged, production safety risks are reduced, and therefore the purpose of protecting the centrifugal pump is achieved.

Detailed Description
The utility model is described in further detail below with reference to the following detailed description and accompanying drawings:
a safe centrifugal pump unloading device comprises a material buffer tank 1, wherein a liquid level meter 2 is arranged on the material buffer tank 1, an unloading pipeline 3 is connected to the upper portion of the material buffer tank 2, a feed valve 4 and a flange 5 are sequentially arranged on the unloading pipeline 3 from right to left, and the unloading pipeline 3 is connected with an unloading crane pipe 6 through the flange 5; the bottom of the material buffer tank 2 is connected with a centrifugal pump 8 through a material pipeline I7, a centrifugal pump inlet valve 9 is arranged at the end, close to the centrifugal pump 8, of the material pipeline I7, the centrifugal pump 8 is connected with a material receiving tank 11 through a material pipeline II 10, and a centrifugal pump outlet valve 12 is arranged at the end, close to the centrifugal pump 8, of the material pipeline II 10.
Further, a pressure gauge 13 is arranged between the centrifugal pump 8 and the centrifugal pump outlet valve 12, and the running condition of the centrifugal pump 8 is judged through the pressure gauge 13.
Further, the dump arm 6 is connected to a tank car 14, the tank car 14 containing material to be unloaded to the material receiving tank 10.
When unloading operation is carried out, materials of the tank car sequentially pass through the material buffer tank 1 and the centrifugal pump 8 and finally enter the material receiving tank 10. The material buffer tank 1 is provided with the liquid level meter 2, the liquid level meter 2 is convenient for monitoring the material liquid level change in the material buffer tank 1, when the liquid level meter 2 is used for observing the material liquid level in the material buffer tank 1 to descend, the situation that the material in the tank car 14 is unloaded is shown, the material in the tank car 14 does not enter the material buffer tank 1 any more, at the moment, the centrifugal pump 8 is stopped in time, and the situation that the material in the material buffer tank 1 is evacuated to prevent the idling of the centrifugal pump 8 is caused.
Through setting up material buffer tank 1, field operation personnel can in time stop the pump according to the liquid level change in the material buffer tank 1. The phenomenon that the centrifugal pump 8 is damaged due to idling of the centrifugal pump 8 is avoided, manual operation is reduced, working efficiency is improved, the service life of the centrifugal pump 8 is prolonged, production safety risks are reduced, and therefore the purpose of protecting the centrifugal pump 8 is achieved.
The above detailed description of the embodiments of the present invention is provided as an example, and the present invention is not limited to the above described embodiments, and equivalent modifications of the present invention are within the scope of the present invention.
