Description
Technical field
The utility model relates to experimental branch line technical field, especially a kind of esterification EG flusher.
Background technique
In the prior art, high-temperature polyester EG is formed into its slurry with after the cooperation of other raw materials in slurry preparation, the slurry
The temperature of material can reduce, and cause its viscosity etc. to increase, be easy to cause at the bottom valve and slurry delivery pump of slurry preparation pot bottom
It blocks, needs operator to switch slurry delivery pump etc., and dredge to it, seriously affect production efficiency and production
Stability.
Utility model content
There is provided purpose of the utility model is to solve the deficiency of above-mentioned technology a kind of effectively can avoid slurry from conveying
The esterification EG flusher blocked at pump and bottom valve.
In order to achieve the above object, a kind of esterification EG flusher designed by the utility model, including esterification EG tank, slurry
Expect that preparing tank, slurry feed tank, No.1 pipeline is provided between the bottom of esterification EG tank and the upper end of slurry preparation, one
It is disposed with esterification EG delivery pump, esterification EG regulating valve, flow valve from esterification EG tank to slurry preparation direction on number pipeline,
No. two pipelines are provided between the bottom of slurry preparation and slurry feeding tank, from slurry preparation to slurry on No. two pipelines
Material feeding tank direction sets gradually bottom valve, flowmeter, slurry delivery pump, outlet valve, sets between No.1 pipeline and No. two pipelines
It is equipped with clean-up line, ball valve is provided on clean-up line, one end of clean-up line is connected to esterification EG regulating valve and flow valve
Between No.1 pipeline on, the other end of clean-up line is connected on No. two pipelines between bottom valve and flowmeter.
Above-mentioned technical proposal, in equipment normal course of operation, the ball valve on clean-up line is closed, and is esterified EG normally from one
Number pipeline enters slurry preparation, is configured to export from No. two pipelines to slurry after slurry to feed tank, during this process, when No. two
When the flow-reduction of pipeline flow meter, then prove that some position on No. two pipelines occurs blocking and dredged；This
Shi Kaiqi ball valve turns down or closes flow valve, and high temperature esterification EG then passes through clean-up line and enters at bottom valve, closes outlet valve, then
Being esterified EG can enter inside slurry preparation, only change the mode that esterification EG enters slurry preparation, so to slurrying is matched
Material does not influence, but when entering slurry preparation at bottom valve, increases to the temperature in the regions such as bottom valve, to promote slurry
Mobility realizes its dredging,, can will be whole when opening outlet valve furthermore such that the bottom slurry temperature in slurry preparation increases
A No. two pipelines carry out heating dredging, the smoothness of lifting means operation.When equipment restores normal, ball valve can be closed, institute
It is operated normally with equipment.
It further include controller, controller is uniformly controlled esterification EG delivery pump, esterification EG regulating valve, flow valve, ball valve, bottom
Valve, slurry delivery pump and outlet valve.The design of the structure, the controller for being able to achieve all components in controller are adjusted automatically
Section realizes that equipment carries out auto-flushing operation.
A kind of obtained esterification EG flusher of the utility model, is designed by reasonable structure, can utilize high temperature
Esterification EG carries out heating flushing, lifting means operation to the component on No. two pipelines between slurry preparation and slurry feeding tank
Stability and reliability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Below by embodiment combination attached drawing, the utility model will be further described.
Embodiment 1:
As shown in Figure 1, the present embodiment description a kind of esterification EG flusher, including esterification EG tank 1, slurry preparation 2,

Esterification EG delivery pump 4, esterification EG regulating valve 5, flow valve are disposed with from esterification EG tank 1 to 2 direction of slurry preparation on line 7
6, No. two pipelines 8 are provided between the bottom of slurry preparation 2 and slurry feeding tank 3, by slurry preparation on No. two pipelines 8
Tank 2 sets gradually bottom valve 11, flowmeter 12, slurry delivery pump 13, outlet valve 14 to slurry feeding 3 direction of tank, in No.1 pipeline 7
It is provided with clean-up line 9 between No. two pipelines 8, ball valve 10, one end connection of clean-up line 9 are provided on clean-up line 9
On No.1 pipeline 7 between esterification EG regulating valve 5 and flow valve 6, the other end of clean-up line 9 is connected to bottom valve 11 and flow
On No. two pipelines 8 between meter 12.
It further include controller, controller is uniformly controlled esterification EG delivery pump 4, esterification EG regulating valve 5, flow valve 6, ball valve
10, bottom valve 11, slurry delivery pump 13 and outlet valve 14.
