Model utility content
The utility model proposes a kind of liquid-supplying system, solved the problem of liquid-supplying system list pump feed flow, maintenance difficulty and the impact production of existing seed-coating machine.
The technical solution of the utility model is achieved in that and comprises liquid container, and described liquid container is connected with seed-coating machine by pipeline; Mechanical pump, described mechanical pump is 2, is installed in parallel on the connecting tube of described liquid container and described seed-coating machine; Closed circuit valve, described closed circuit valve is 2, lays respectively on the connecting tube of described liquid container and described mechanical pump; Safety check, comprise the first safety check, the second safety check and the 3rd safety check, described the first safety check and described the second safety check are installed on the pipeline between described mechanical delivery side of pump and the material feeding mouth of described seed-coating machine, and the 3rd safety check is installed between described the first safety check and the second safety check.
As preferred technological scheme, described closed circuit valve is one or both in stop valve, ball valve, gate valve, butterfly valve, stopcock, needle type valve or membrane valve.
As preferred technological scheme, described cut-off valve door is connected with power supply by electric wire.
As preferred technological scheme, described safety check is corrosion resistance valve.
As preferred technological scheme, described liquid-supplying system is connected with control panel.
Workflow:
When seed-coating machine normally moves, open the closed circuit valve on article one pipeline, start corresponding mechanical pump, the liquid in liquid container flows to seed-coating machine by article one pipeline through the first safety check and the 3rd safety check; Meanwhile, the second safety check on second pipeline has effectively stoped liquid by the backflow of second pipe; When article one feed liquid pipeline breaks down, close mechanical pump and closed circuit valve on article one pipeline, open the closed circuit valve on second pipeline, and start corresponding mechanical pump, liquid in liquid container flows to seed-coating machine by second pipeline through the second safety check and the 3rd safety check, and the first safety check on article one pipeline has effectively stoped liquid by the backflow of article one pipeline; Then, can overhaul fault pipeline, and not affect normal production.
The utility model is compared produced beneficial effect with background technique:
The mode that adopts two pumps parallel connection, by a throw over switch, flow direction can switch easily between two pumps; The piping design of 3 non-returns of this two-stage, has avoided the interference between two pumps, while breaking down, can realize on-line maintenance.
