Description
Technical field
The utility model belongs to process for cleanly preparing and equipment technology field, especially relates to a kind of chemical device for discharging.
Background technology
The liquid charging stock of chemical plant large usage quantity be usually all by groove tank car by aproll feedstock delivery to factory, directly be discharged in the raw material storage tank of tank field by discharging pump and pipeline, the raw material in raw material storage tank is directly squeezed in the process units of producing tract by discharging pump, flow counter and pipeline again.Can save like this in the packing barrel of raw material and factory and go out the carrying links such as warehouse-in, workshop be reinforced, be easy to realize Chemical Manufacture closed-loop operation, shorten and produce feed time, realize Auto-control of the process, meet the requirement of safety in production and cleaner production.
Due to part material tank volume all at hundreds of to a few kilostere, when in stock tank, raw material liquid level reach a certain height, the inlet point unloading position static pressure inserting pot bottom increases, in groove tank car, remaining raw material is difficult to flow in stock tank by self gravitation, usual enterprise adopts toward the pressurization of tank car inflated with nitrogen, make between tank car and stock tank, there is certain pressure reduction, make chemical flow to stock tank to complete discharging.It is high that discharging has just started liquid level in time slot tank car, in storage tank, liquid level is low, so by discharging pump can very fast speed by feedstock transportation in stock tank, the raw material of 80% approximately just can be unsnatched at 1 hours, but all the other 20% need within about 3-4 hour, can complete, bottom groove tank car, the raw material of about 5% is difficult to normally draw off.The cleaning company cleaning of specialty will be delivered to after the unloading of groove tank car, because there being chemical remaining, need additional waste collection and environmental protection treatment expense, waste raw material, several links of discharging simultaneously both increase cost, and in discharge process, along with the rising of stock tank pressure, the difficulty that discharging also becomes thereupon, in order to reduce the pressure of stock tank, needs to carry out emptying to stock tank, just there is very large potential safety hazard in this, noxious gas easily leaks in air in emptying process, contaminated environment, the more important thing is and easily sets off an explosion; Therefore there is the problem of poor stability.
Summary of the invention
The purpose of this utility model is to provide a kind of chemical device for discharging, effectively can shorten dumping time, and safety is high.
For achieving the above object, the technical solution adopted in the utility model is: a kind of chemical device for discharging, comprise groove tank car, transfer tank, stock tank and nitrogen pot, it is characterized in that: described groove tank car is provided with the side that the first pipeline is connected to described transfer tank, the opposite side of described transfer tank is provided with second pipe and connects described stock tank, described stock tank top is nitrogen tube, described nitrogen tube connects described nitrogen pot, described nitrogen pot top is provided with nitrogen inlet, described nitrogen pot bottom is provided with equalizing pipe, described equalizing pipe bottom is provided with nitrogen interface, described equalizing pipe, described first pipeline, described second pipe is all provided with check valve, described second pipe is also provided with discharging interface and discharging pump.
Preferably, described first pipeline is connected by the 3rd pipeline with between described second pipe.
Preferably, described transfer tank inside is provided with filtering net.
The advantage that the utility model has and good effect are: simple and practical, by the surplus stock in groove tank car is transported in transfer tank, and then be transported in stock tank by transfer tank, significantly can shorten the dumping time of groove tank car, simultaneously, make discharging more thorough, decrease the raw material residual quantity in groove tank car, reduce material loss, save cost, realize the cleaner production of discharging link, and nitrogen, chemical are all in the space of a sealing in discharge process, therefore can not produce leakage, safety is better.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, groove tank car; 2, stock tank; 3, the first pipeline; 4, transfer tank; 5, discharging pump; 6, second pipe; 7, filtering net; 8, the 3rd pipeline; 9, check valve; 10, nitrogen tube; 11, nitrogen pot; 12, nitrogen inlet; 13, equalizing pipe; 14, nitrogen interface; 15, discharging interface.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1:
As shown in Figure 1, the utility model provides a kind of chemical device for discharging, comprise groove tank car 1, transfer tank 4, stock tank 2 and nitrogen pot 11, groove tank car 1 is provided with the side that the first pipeline 3 is connected to transfer tank 4, the opposite side of transfer tank 4 is provided with second pipe 6 and connects stock tank, stock tank 2 top is nitrogen tube 10, nitrogen tube 10 connects nitrogen pot 11, nitrogen pot 11 top is provided with nitrogen inlet 12, nitrogen pot 11 bottom is provided with equalizing pipe 13, equalizing pipe 13 bottom is provided with nitrogen interface 14, equalizing pipe 13, first pipeline 3, second pipe 6 is all provided with check valve 9, second pipe 6 is also provided with discharging interface 15 and discharging pump 5.
Preferably, the first pipeline 3 is connected by the 3rd pipeline 8 with between second pipe 6.
Preferably, transfer tank 4 inside is provided with filtering net 7, prevents impurity from entering in stock tank 2, easy cleaning stock tank 2.
The working process of this example: first by discharging pump 5 by groove tank car 1 about 80% raw material be directly delivered in stock tank 2 from second pipe 6 in one hour.When residue in groove tank car 1 is greater than the raw material of 20%, operator closes the valve on second pipe 6, opens the valve on the first pipeline 3, by remaining feedstock transportation in transfer tank 4, and then passes through transfer tank 4 by remaining feedstock transportation in stock tank 2.Due to the volume of transfer tank 4 with highly all much smaller than stock tank 2, and fed distance is short, thus groove tank car 1 can easily by feedstock transportation in transfer tank 4, nitrogen pot 11 can realize stock tank 2, the balance of nitrogen between groove tank car 1; Check valve 9 on second pipe 6 can prevent from preventing chemical from refluxing in the hypodynamic situation of transport pump; Check valve 9 on equalizing pipe 7 can prevent nitrogen reflux.Through practical test, the dumping time of groove tank car 1 can by original four to five hours, foreshorten to one or two hour, and the raw material in groove tank car 1 is pumped substantially, decreased the expense of waste collection and process when wastage of material and groove tank raffinate entrust cleaning outward.
The utility model is simple and practical, by a part of feedstock transportation of extraction will be difficult in groove tank car 1 in transfer tank 4, and then be transported in stock tank 2 by transfer tank 4, significantly can shorten the dumping time of groove tank car 1, simultaneously, make discharging more thorough, decrease the raw material residual quantity in groove tank car 1, reduce material loss, save cost, realize the cleaner production of discharging link, and nitrogen, chemical are all in the space of a sealing in discharge process, therefore can not produce leakage, safety is better.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
