Abstract
The utility model discloses a poisonous chemical material discharging device for chemical fiber production. The poisonous chemical material discharging device comprises a raw material tank and a nitrogen tank, wherein a nitrogen pipe is arranged at the upper part of the raw material tank, and a feeding pipe is arranged at the lower part of the raw material tank and is provided with a feeding port; the nitrogen tank is provided with a nitrogen inlet and is communicated with the nitrogen pipe; a balance pipe is arranged at the lower part of the nitrogen tank, and a nitrogen port is arranged at the lower part of the balance pipe; the balance pipe and the feeding pipe are provided with check valves; and a feeding pump is arranged on the feeding pipe. When the poisonous chemical material discharging device is used, chemical materials are pumped into the raw material tank by the feeding pump, and the balance of nitrogen between the raw material tank and a tank car can be kept by the nitrogen tank; the check valve on the feeding pipe can prevent the poisonous chemical materials from flowing back when the transport force of the pump is insufficient; the check valve on the balance pipe can prevent the nitrogen from flowing back; and during a discharging process of the poisonous chemical material discharging device, the nitrogen and the chemical materials are arranged in a closed space, so that the leakage of the nitrogen and the chemical materials is prevented, and the safety is higher.
Description
Technical field
The utility model relates to the raw material device for discharging in a kind of chemical fibre field, especially a kind of poisonous chemical device for discharging for chemical fibre production.
Background technology
In production of chemical fibres, usually need to relate to some poisonous chemical, (epoxyethane is a kind of high poison, inflammable, explosive dangerous chemical such as epoxyethane, boiling point is 10.4 ℃, explosive limits is very wide, in case leak, vaporization all can set off an explosion in 3%～85% scope rapidly).Adopt the groove tank car to finish during these poisonous chemical transportations, therefore to have one with chemical from discharging in the groove tank car to the process of stock tank, and the common enterprise of this discharge process adopts toward the pressurization of tank car inflated with nitrogen, making has certain pressure reduction between tank car and stock tank, make chemical flow to stock tank and finish discharging.In discharge process, rising along with stock tank pressure, the difficulty that discharging also becomes thereupon, in order to reduce the pressure of stock tank, need to carry out emptying to stock tank, just there is very large potential safety hazard in this, and noxious gas easily leaks in the air in the emptying process, contaminated environment be the more important thing is easily to set off an explosion; Therefore the problem that has poor stability.
Summary of the invention
The purpose of this utility model is a kind of poisonous chemical device for discharging that chemical fibre is produced that is used for of effectively guaranteeing discharging safety that designs for the deficiency that solves above-mentioned technology.
The poisonous chemical device for discharging that is used for chemical fibre production that the utility model is designed, comprise stock tank, stock tank top is nitrogen tube, and the bottom is provided with feed pipe, feed pipe is provided with the charging interface, also comprise nitrogen pot, nitrogen pot is provided with nitrogen inlet, and described nitrogen tube is communicated with nitrogen pot, the nitrogen pot bottom is provided with equalizing pipe, the equalizing pipe bottom is provided with nitrogen interface, all is provided with check valve on equalizing pipe, the feed pipe, is provided with feed pump at feed pipe.
Described nitrogen pot bottom is provided with support, and described equalizing pipe is flexible pipe.
The poisonous chemical device for discharging that is used for chemical fibre production that the utility model is designed during use, utilizes feed pump that chemical is squeezed into stock tank, and nitrogen pot can be realized the balance of nitrogen between stock tank, the groove tank car; Check valve on the feed pipe can prevent from carrying at pump and prevent in the hypodynamic situation that poisonous chemical from refluxing; Check valve on the equalizing pipe can prevent nitrogen reflux; This poisonous chemical device for discharging for chemical fibre production all is in the space of a sealing at discharge process nitrogen, chemical, therefore can not produce leakage, and safety is better.
