In the first pipeline work, the second valve is closed, and the second gate valve is located at the end of second pipe, threeway
There is no salt slurry siltation area between connector and the second gate valve, it is therefore prevented that caused by the defeated salt slurry siltation of the first salt slurry pump work luck
Line clogging.
Further, the 3rd pipeline is located along the same line with the first pipeline or second pipe.The bend in pipeline is reduced,
Reduce the operating load of the first brine pump or the second brine pump.
Further, the first pipeline and/or second pipe are equipped with flowmeter.Flowmeter use is welded, is spirally connected, flange connects
The mode such as connect to be arranged on the first pipeline or second pipe.Flowmeter is used to detect the first pipeline and/or second pipe
Salt slurry flow.
Further, the first pipeline and/or second pipe are equipped with check valve.Check valve use is welded, is spirally connected, flange connects
The mode such as connect to be arranged on the first pipeline or second pipe.Check valve is used to prevent the first pipeline and/or second pipe
Salt slurry reflux.
Further, PLC control cabinet, PLC control cabinet and the first gate valve, the second gate valve, the first brine pump, the second salt are further included
Stock pump is connected with flowmeter.First gate valve, the second gate valve, the first brine pump and the second brine pump are controlled by PLC control cabinet
Working status, realizes the automatic running of whole process, and the operation for switching brine pump is more convenient.
The beneficial effects of the utility model：
By varying the position of gate valve, the distance of three-way connection and the second gate valve shortens, shortens existing the utility model
The length of the salt slurry siltation pipeline caused by stopping transporting in technology, it is therefore prevented that the defeated salt slurry siltation of the first salt slurry pump work luck
Caused line clogging.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and embodiments.
Embodiment 1
With reference to Fig. 2, a kind of transfer pipeline for salt slurry conveying, including the first pipeline 1, second pipe 2, the 3rd pipeline 3,
First gate valve 4 and the second gate valve 5, the first pipeline 1 and 2 front end of second pipe are connected to the first brine pump 6 and the second salt slurry
Pump 7, end is crossed by three-way connection 8, and three-way connection 8 is connected with the 3rd pipeline 3, the first gate valve 4 and the second gate valve 5 difference position
In the end of the first pipeline 1 and second pipe 2.
When the first brine pump 6 works, the second brine pump 7 does not work, salt slurry by after three-way connection 8 through the 3rd pipeline 3
Transport, the second gate valve 5 is closed at this time, because the second gate valve 5 is located at the end of second pipe 2, three-way connection 8 and second
There is no salt slurry siltation area between gate valve 5.
Embodiment 2
With reference to Fig. 3, embodiment 2 is substantially the same manner as Example 1, its difference is：
3rd pipeline 3 is located along the same line with the first pipeline 1.
Flowmeter 10 is welded with second pipe 2.
Check valve 11 is welded with second pipe 2.
Since conveying salt slurry is heterogeneous fluid, proportion is larger, and the bend of pipeline is more, and Transport resistance is bigger, increases
The operating load of brine pump.3rd pipeline 3 is located along the same line with the first pipeline 1 or second pipe 2, it is possible to reduce first
The operation that the bend number of the either 2 one of pipeline of second pipe of pipeline 1 reduces the first brine pump 6 or the second brine pump 7 is born
Lotus.In the present embodiment, the 3rd pipeline 3 is located along the same line with the first pipeline 1, from the salt slurry of the first brine pump 6 outflow through the
One pipeline 1 is directly entered three-way connection 8, halfway without bend, therefore reduces the operating load of the first brine pump 6.
Flowmeter 10 is used to detect the salt slurry flow of second pipe 2, when the second brine pump 7 is in running order, flow
The salt slurry flow of the display second pipe 2 of meter 10.Coordinate check valve 11, it is necessary to when switching to the work of the first brine pump 6, first close the
Two brine pumps 7, after the salt slurry flow-reduction that flowmeter 10 is shown, close the second valve 5, since the prevention of check valve 11 flows back
Effect, the salt slurry in second pipe 2 drains substantially at this time, it is therefore prevented that when the second brine pump 7 is out of service, because of second pipe 2
In remain excessive salt slurry and deposit cause second pipe block phenomenon.
Similarly, flowmeter 10 is arranged on the first pipeline 1, the salt slurry flow in the first pipeline 1 can be detected；In the first pipe
Check valve 11 is set on road 1, the phenomenon for coordinating flowmeter 10 to prevent the first pipeline 1 from blocking.Therefore preferred solution is first
Flowmeter 10 and check valve 11 are respectively provided with pipeline 1, second pipe 2.
Embodiment 3
With reference to Fig. 4, the embodiment 3 and the difference of embodiment 2 of the utility model are：
Transfer pipeline provided in this embodiment for salt slurry conveying further includes PLC control cabinet 9, PLC control cabinet 9 and first
Gate valve 4, the second gate valve 5, the first brine pump 6, the second brine pump 7 and flowmeter 10 connect.
In advance after 10 given threshold of flowmeter, the second brine pump 7 of closing, when flowmeter 10 is detected in second pipe 2
Salt slurry flow when being less than the threshold value, send a signal to PLC control cabinet 9, PLC control cabinet 9 controls the second gate valve 5 to close, first
Gate valve 4 is opened, the first brine pump 6 starts, and realizes the automatic running of whole process, the operation for switching brine pump is more convenient.
