Abstract
The utility model provides a dual-circuit switching device of a spray condenser used for a polyester unit. The dual-circuit switching device comprises a flow meter, an annular pipeline, a spray condenser, a circulating pump and a hot well, wherein the annular pipeline comprises a first annular pipeline and a second annular pipeline, and processing material in the hot well are transported to the spray condenser through a circulating pump, the flow meter and one of the annular pipelines by switching a valve. The aim that two annular pipelines can be switched and cleaned at any time with no need of artificially stopping the dual-circuit switching device to clean the annular pipelines can be achieved. Finally, the long-period stable operation can be realized, and the dual-circuit switching device has great significances for the stability of production.
Description
Technical field
The utility model relates to the Weaving device field, particularly, relates to a kind of spray condenser double-circuit switching device shifter for polyester device.
Background technology
In the Yi Wenda polyester device, the poly-spray system of final minification is easily dirty in the high yield situation, especially the ring pipe of the poly-spray condenser of final minification is the part of spray system, be easy to gather and stop up gradually at this position oligomer, cause spray flow and pressure to reduce gradually, badly influence vacuum and security of system.
Especially in the high yield situation, prove according to actual production, using about 2 months that the EG spraying ring pipe is connected the obstruction of valve place and reaches more than the 20mm with pipeline, make original 100mm latus rectum only about surplus 50mm; In addition, the endless tube of spray condenser and nozzle junction are stopped up more serious and can't be cleared up, and do not unpick and wash if there is endless tube for subsequent use to switch, and the spray condenser annulus line can't be unpicked and washed after stopping up, can only stop to process by technique, system can't long-term operation.
The utility model content
In order to address the above problem, the utility model proposes a kind of spray condenser double-circuit switching device shifter and method for polyester device.
A kind of spray condenser double-circuit switching device shifter for polyester device, this device comprises flowmeter, annulus line, spray condenser, circulating pump and hot well, wherein,
Described annulus line comprises the first annulus line and the second annulus line;
Rapidoprint in the described hot well, is switched along one in the described two-way annulus line described spray condenser of arrival by valve through described meter by described circulating pump.
Further, described the first annulus line and described the second annulus line have respectively terminal valve.
Further, described the second annulus line size is less than the first annulus line.
Further, described annulus line is made by metal hose.
In addition, the utility model proposes a kind of spray condenser double-circuit changing method for polyester device, rapidoprint in the described hot well is by the described meter of described circulating pump process, open the second annulus line terminal valve, close the first annulus line terminal valve, arrive the described spray condenser of rapidoprint.
As a kind of preferred version, described the second annulus line size is less than the first annulus line.
As a kind of preferred version, described annulus line is made by metal hose.
By above-mentioned two collar-shaped pipelines, reach the purpose that can switch at any time, clean ring pipe, do not clear up and do not need technique to stop, and finally can reach long-period stable operation, stable very important meaning arranged to what produce.
Description of drawings
Fig. 1 shows the operation chart of the spray condenser double-circuit switching device shifter that is used for polyester device that the utility model proposes.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that embodiment described herein only is used for explaining the utility model, rather than be used for restriction the utility model.
As shown in Figure 1, a kind of spray condenser double-circuit switching device shifter for polyester device that the utility model proposes comprises flowmeter, annulus line, spray condenser, circulating pump and hot well, wherein,
Described annulus line comprises the first annulus line and the second annulus line;
Rapidoprint in the described hot well, is switched along one in the described two-way annulus line described spray condenser of arrival by valve through described meter by described circulating pump.
Further, described the first annulus line and described the second annulus line have respectively terminal valve.
In preferred embodiment of the present utility model, described the second annulus line size is less than the first annulus line, and described annulus line is made by metal hose.
In addition, the utility model proposes a kind of spray condenser double-circuit changing method for polyester device, rapidoprint in the described hot well is by the described meter of described circulating pump process, open the second annulus line terminal valve, close the first annulus line terminal valve, arrive the described spray condenser of rapidoprint.
As a kind of preferred version, described the second annulus line size is less than the first annulus line, and described annulus line is made by metal hose.
Enforcement of the present utility model can be dismantled and thoroughly cleaning a collar-shaped pipeline wherein, guarantee clean after recovery system as for subsequent use.The first annulus line and the second annulus line can be for subsequent use each other.
Above-mentioned only is preferred embodiment of the present utility model, certainly, with further exploration other embodiment can also be arranged according to actual needs.But, should be clear and definite be that the conversion based on similar embodiment with same idea above-mentioned or that other is not explained out all should be encompassed within the protection domain of the utility model claim
