A solvent split charging device is characterized in that a bending section 2 is arranged on a feeding pipe 1, and the bending section 2 is positioned at the feeding pipe 1 above an outer cylinder 3; the feeding pipe 1 is also communicated with an exhaust pipe 7, and an exhaust valve 8 is arranged at the outlet of the exhaust pipe 7; the distance between the bottom end of the cover body 4 and the bottom end of the outer cylinder body 3 is d, and d is more than or equal to 100 mm; the exhaust valve 8 and the overflow valve 9 both adopt quick-opening ball valves, and the pressure-resistant grade of the quick-opening ball valves is 1.6 Mpa; the feeding pipe 1, the outer barrel 3 and the overflow pipe 10 are all made of stainless steel; the feed end of the feed pipe 1 is connected with a feed valve 11. The structure and connection relationship of the rest parts are the same as those described in any of the foregoing embodiments, and are not described herein again to avoid the tedious text.

On the basis of the above embodiments, the present invention proceeds with detailed descriptions of technical features and functions thereof, so as to help those skilled in the art fully understand the technical solution of the present invention and reproduce it.

As shown in fig. 1, in the present invention, the inlet pipe 1 is connected to the discharge port of the tank body through the pipe body, the tert-butylamine in the tank body enters the inlet pipe 1 through the pipe body, in order to avoid the height of the inlet pipe 1 being too high or further increasing the operation space, the inlet pipe 1 can be provided with the bending section 2, the bending angle of the bending section 2 is between 100 degrees and 130 degrees, in the present invention, it is preferable that 120 degrees. The bending direction of the bending section 2 is not oriented towards the orientation in which the overflow pipe 10 or the exhaust pipe 7 is located.

The utility model discloses in, 2 below inlet pipes 1's of bending section outer barrel 3 is fixed with on the outer wall, outer barrel 3's top shutoff and with inlet pipes 1's outer wall fixed connection, outer barrel 3's bottom opening and with inlet pipes 1's outer wall between form overflow intermediate layer 6. Because the feeding pipe 1 and the outer cylinder 3 are coaxially arranged, an overflow interlayer 6 formed between the feeding pipe 1 and the outer cylinder 3 is consistent in the length direction of the feeding pipe 1. An overflow pipe 10 is further fixed on the outer cylinder body 3, the overflow pipe 10 is communicated with the overflow interlayer 6, and an overflow valve 9 can be connected at an outlet of the overflow pipe 10 for recovering tert-butylamine flowing out of the overflow interlayer 6.

The utility model discloses in be provided with blast pipe 7 on the inlet pipe 1 between bending segment 2 and the 3 tops of outer barrel, blast pipe 7 link up with inlet pipe 1. In the emptying process, the exhaust pipe 7 should be in a closed state, and after emptying is completed and overflow is finished, the exhaust pipe 7 is in an open state, so that an exhaust valve 8 can be arranged at an outlet of the exhaust pipe 7 to realize the above functions.

Specifically, the utility model discloses when using, at first need be connected lid 4 and cock body 5 in the entry of staving, open charge-in valve 11, overflow valve 9 this moment for the tert-butylamine of saving in jar body enters into inlet pipe 1 through the pipeline, and enters into the staving of treating the partial shipment through inlet pipe 1. Since the inlet of the drum is blocked by the cover 4 and the stopper 5, the air in the drum is discharged through the overflow pipe 10. Over time, the tert-butylamine in the barrel body gradually increases until the tert-butylamine flows out through the overflow interlayer 6 at the outer barrel body 3 and the feeding pipe 1, and the tert-butylamine flowing out from the overflow interlayer 6 is temporarily stored in the collecting barrel. At this time, the feeding valve 11 on the feeding pipe 1 is closed, and the surplus tert-butylamine in the barrel body can continue to be discharged through the overflow interlayer 6 and the overflow pipe 10 until the liquid level of the tert-butylamine in the barrel body is lower than the inlet of the overflow interlayer 6 (i.e. lower than the bottom end of the outer barrel body 3), and the overflow pipe 10 can not discharge the tert-butylamine outwards. At the moment, the exhaust valve 8 on the exhaust pipe 7 is opened, the overflow valve 9 on the overflow pipe 10 is closed, and the cover body 4, the plug body 5 and the feeding pipe 1 positioned in the barrel are moved out of the barrel after the exhaust is finished. And screwing the barrel body to the cover body to complete the split charging operation.

In the process, the distance d between the cover body 4 and the inlet end of the overflow interlayer 6 is set to a numerical value of d according to the size of the barrel body, so that the weight/volume of tert-butylamine contained in the barrel body can be adjusted. Generally, for a 200L bucket containing 135Kg of tert-butylamine, d can be set to about 100 mm.

Finally, although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description of the present description is for clarity reasons only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
