The technical scheme of the utility model is as follows:
The utility model provides a dirty oil tank, includes the barrel, locates the head at barrel both ends, locates the saddle of barrel bottom, first manhole and the second manhole at barrel top are located to the interval, and its technical essential is: be equipped with first apron and be equipped with temperature transmitter mouth, level gauge mouth and nitrogen gas entry on the first apron on the first manhole, be equipped with the feed pipeline in the first manhole, the lateral wall of first manhole is crooked and is drawn forth to the feed pipeline upper end, and the feed pipeline lower extreme extends to the barrel head and keeps setting for the interval, and the barrel head is equipped with the shock-resistant board that corresponds feed pipeline lower port, be equipped with pressure transmitter mouth, manometer mouth, air vent and ejection of compact pipeline on being equipped with second apron and the second apron on the second manhole, the lower extreme of ejection of compact pipeline extends to the barrel head and keeps setting for the interval.
According to the sewage tank, the reinforcing ring is arranged in the middle of the wall of the cylinder body or is arranged outside the middle of the wall of the cylinder body, and the reinforcing ring is made of flat steel or angle steel. So as to prevent the tank from being unstable due to negative pressure in the tank when dirty oil is pumped out.
The length of the shell ring of the first manhole and the second manhole is greater than 1/2 of the diameter of the shell.
The number of the saddles is two, one saddle is a fixed seat, and the other saddle is a movable seat.
The beneficial effects of the utility model are as follows:
1. The opening structure on the cylinder is only two, namely a first manhole and a second manhole. The first cover plate of the first manhole is provided with a temperature transmitter port, a liquid level meter port and a nitrogen inlet, the first manhole is utilized to support a feeding pipeline, and the second cover plate of the second manhole is provided with a pressure transmitter port, a pressure meter port, a vent and a discharging pipeline. The utility model solves the problem that the strength of the cylinder body is weakened due to more opening structures of the traditional sewage tank, and the strength of the cylinder body is not required to be enhanced by increasing the number of reinforcing rings. Meanwhile, the opening structure is few, so that landfill construction is facilitated.
2. The feeding pipeline and the discharging pipeline all adopt inward extending structures, namely all extend to the bottom of the cylinder and keep a set distance to form a liquid seal, so that storage safety is guaranteed, and meanwhile, an impact-resistant plate is arranged for avoiding continuous flushing of a medium on the cylinder.
3. This jar has set up nitrogen gas entry, its purpose: firstly, because flammable and explosive gas exists, nitrogen needs to be filled, so that inert atmosphere is formed inside the equipment, and the occurrence probability of accidents is reduced; secondly, nitrogen can be used for purging equipment to replace; thirdly, when dirty oil is pumped out by a pump, nitrogen can be filled for pressure compensation in order to avoid the too low pressure in the tank.
