Background technology：
Hexamethylene diamine can be crystallized less than 41 DEG C, in existing loading-unloading vehicle system, generally be used at the modes such as heat tracing
Reason, to prevent from crystallizing, but since pipe fitting existing for loading-unloading vehicle is more, simple heat treatment easy tos produce dead angle, if generating
Dead angle then generally can all be caused to crystallize less than 41 DEG C due to room temperature or outside air temperature and block pipeline, block pipeline it
Afterwards, it is blocked if wanting to remove, it is very big to be accurately positioned blocking position difficulty, and therefore, it is time-consuming and laborious to remove work, leverages dress
Unload efficiency, and if block and be switched on by force, it is possible to cause the unusual conditions such as pump idle running to occur, burnt so as to cause pump motor
Accident, there is no the plans of solution to this for the prior art.
Utility model content：
The utility model provides a kind of hexamethylene diamine loading-unloading vehicle system, and system is reliable, is purged after use, and advance is used
Row detection, solves problems of the prior art.
Used technical solution is the utility model to solve above-mentioned technical problem：
A kind of hexamethylene diamine loading-unloading vehicle system, including storage tank, storage tank are connected with handling pump by going out stockline, are set on going out stockline
There are the first connection flexible pipe and pressure alarm, handling pump to be connected with tank car by pumping line, the pumping line passes through a by-pass line
It is connected with storage tank, is additionally provided with first filter on pumping line, a nitrogen line is also connected on the pumping line after first filter,
It is additionally provided with a purging line on the nitrogen line with the pumping line before first filter to be connected, it is soft that the second connection is equipped on pumping line
Pipe and flow control valve are equipped with a switch valve in pumping line discharge end, a ultralow pressure nitrogen are connected on the pumping line after switch valve
Gas line, the ultralow pressure nitrogen line are connected by a quick coupling with pumping line.
Preferably, check-valves is equipped on nitrogen line.
Preferably, the switch valve is ball valve.
Preferably, the second filter is equipped on going out stockline.
Preferably, short circuit is equipped in pumping line and between going out stockline to bypass.
Using the above structure, system is reasonable for the utility model, to reach the purpose, mainly uses two kinds of measures：1, it sets
Nitrogen tube is set, after completing loading-unloading vehicle operation, is purged, avoids remaining hexamethylene diamine in pipeline, handling have substantially been prevented
Stopping state after vehicle completion；2, setting ultralow pressure nitrogen line is for judging whether the pipeline of entrucking pipeline and its storage tank generates
The caused burn-down of electrical machinery of phenomena such as blocking, dallying to avoid pump；In addition, during the experiment of the device, ultralow pressure nitrogen
If line is by the direct-connected mode of pipeline, since material pipeline is easily accessible in the pipeline of ultralow pressure nitrogen line in purge,
Line clogging is caused, avoiding material using ready-packaged joint enters in ultralow pressure nitrogen line, improves service efficiency.
Description of the drawings：
Fig. 1 is the schematic diagram of the utility model；
In figure, 1, storage tank, 2, go out stockline, 3, handling pump, the 4, first connection flexible pipe, 5, pressure alarm, 6, pumping line, 7,

Specific implementation mode：
In order to clarify the technical characteristics of the invention, below by specific implementation mode, and its attached drawing is combined, to this reality
It is described in detail with novel.
As shown in Figure 1, a kind of hexamethylene diamine loading-unloading vehicle system, including storage tank 1, storage tank 1 pump 3 phases by going out stockline 2 with handling
Even, the first connection flexible pipe 4 and pressure alarm 5 are equipped on going out stockline 2, handling pump 3 is connected by pumping line 6 with tank car 19,
The pumping line 6 is connected by a by-pass line 18 with storage tank 1, and first filter 7 is additionally provided on pumping line 6, in the first filtering
A nitrogen line 8 is also connected on pumping line 6 after device 7, before a purging line 9 and first filter 7 are additionally provided on the nitrogen line 8
It pumps line 6 to be connected, the second connection flexible pipe 10 and flow control valve 11 is equipped on pumping line 6, one is equipped in pumping 6 discharge end of line
Switch valve 12 connects a ultralow pressure nitrogen line 13 on the pumping line 6 after switch valve 12, and the ultralow pressure nitrogen line 13 passes through one
Quick coupling 14 is connected with pumping line 6.Ultralow pressure nitrogen refers to the nitrogen of 0.1MPa (gauge pressure), and the nitrogen in nitrogen line 8 is
The nitrogen of 0.6MPa.
Check-valves 15 is equipped on nitrogen line 8.Since purging nitrogen pressure is 0.6MPa, check-valves 15, which is added, to be prevented
The generation of unexpected recharge phenomenon is also conducive to stable pressure output.
The switch valve 12 is ball valve.Since hexamethylene diamine is easy to crystallize, ball valve is since the corner that fully closed standard-sized sheet is is less, no
Easily it is detained material.
The second filter 16 is equipped on going out stockline 2.Directly it is connected with storage tank 1 due to going out stockline 2, avoids in storage tank 1
Substance enters handling pump 3, the moving component of damage handling pump 3.
It is equipped with short circuit in pumping line 6 and between going out stockline 2 and bypasses 17.When being convenient for the purging of nitrogen line 8, nitrogen can be made
Handling pump 3 is crossed to be purged.
In use, pumping line 6 is connected with tank car first, ultralow pressure nitrogen line 13 is then passed through into quick union and pump again
Line sending 6 is connected, and the valve of ultralow pressure nitrogen line 13 is then opened, if ultralow pressure nitrogen line 13 is in flow regime, i.e. flow control
Flow measurement instrument on valve 11 processed has registration, illustrates that pipeline communicates, can carry out car loading operation；When carrying out car loading operation,
Hexamethylene diamine passes sequentially through out stockline 2, handling pump 3, pumping line 6, switch valve 12 and enters in tank car, when the hexamethylene diamine in tank car reaches
When to scheduled reserves, car loading operation terminates, and then carries out the 8 purging effect of nitrogen line；Nitrogen line 8 is opened, nitrogen passes through pumping
Line 6, short circuit bypass 17 go out stockline 2 and enter storage tank 1, and another way then by pumping line 6, switch valve 12 enters in tank car,
Next use can be waited for by completing purging.
Above-mentioned specific implementation mode cannot function as the limitation to scope of protection of the utility model, for the skill of the art
For art personnel, any alternate modification or transformation made to the utility model embodiment all fall within the guarantor of the utility model
It protects in range.
Place is not described in detail for the utility model, is the known technology of those skilled in the art of the present technique.
