Abstract
The utility model relates to a filtering device, in particular to a by-pass filtering device for circulating water for a PET (polyethylene terephthalate) granulator, and belongs to the technical field of chemical mechanical equipment. The by-pass filtering device comprises a cooling water pipe (1), a second filter (6) and the granulator (7); wherein the cooling water pipe (1) is connected with an inlet of the second filter (6); an outlet of the second filter (6) is connected with the granulator (7); the cooling water pipe (1) is provided with a third valve (8) and a fourth valve (9); the filtering device is characterized in that the filtering device also comprises a by-pass water pipe (2); the by-pass water pipe (2) is connected on the cooling water pipe (1); and the by-pass water pipe is provided with a first valve (3), a first filter (4) and a second valve (5) from front to back sequentially. The by-pass filtering device is additionally provided with a by-pass filter, so that the filtering quality is ensured and the working efficiency is improved.
Description
(1) technical field
The utility model relates to a kind of filter, relates in particular to the bypass filter of a kind of PET pelleter with recirculated water, belongs to the chemical mechanical equipment technical field.
(2) background technology
Pelleter work the time need be used pelletizing recirculated water, common pelleter with only being provided with a filter on the supply mains, its filter effect is not too desirable.When filter stops up, can only stop to produce, filter is cleaned, so just reduced operating efficiency.
(3) summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of filter quality better, the higher PET pelleter of the operating efficiency bypass filter of recirculated water.
The purpose of this utility model is achieved in that
A kind of PET pelleter bypass filter of recirculated water; comprise cooling water pipe; second filter and pelleter; described cooling water pipe links to each other with the import of second filter; the outlet of described second filter links to each other with pelleter; described cooling water pipe is provided with the 3rd valve and the 4th valve; it is characterized in that: it also comprises Bypass hose; one end of described Bypass hose is positioned on the cooling water pipe of the 3rd valve front end; the other end is positioned on the cooling water pipe of the 4th valve rear end, is provided with first valve on the described Bypass hose from front to back successively; first filter and second valve.
The beneficial effect that the utlity model has is:
This PET pelleter is with the by pass filter of bypass filter by adding of recirculated water; when the by pass filter obstruction, in the time of need changing or safeguard, as long as close the valve of by pass filter; adopt single-filter can make the machine continuation filter and not shut down, improved operating efficiency.
(4) description of drawings
Fig. 1 is the structural representation of the utility model PET pelleter with the bypass filter of recirculated water.
Wherein: cooling water pipe 1, Bypass hose 2, first valve 3, first filter 4, second valve 5, second filter 6, pelleter 7, the 3rd valve 8, the 4th valve 9.
(5) specific embodiment
As Fig. 1, the utility model relates to the bypass filter of a kind of PET pelleter with recirculated water, comprises cooling water pipe 1, Bypass hose 2, first valve 3, first filter 4, second valve 5, second filter 6, pelleter 7, the 3rd valve 8 and the 4th valve 9;
Described cooling water pipe 1 links to each other with the import of second filter 6; the outlet of described second filter 6 links to each other with pelleter 7; described cooling water pipe 1 is provided with the 3rd valve 8 and the 4th valve 9; described the 3rd valve 8 is positioned at the front end of second filter 6; described the 4th valve 9 is positioned at the rear end of second filter 6; described Bypass hose 2 is connected on the cooling water pipe 1; one end of described Bypass hose 2 is positioned on the cooling water pipe 1 of the 3rd valve 8 front ends; the other end is positioned on the cooling water pipe 1 of the 4th valve 9 rear ends, is provided with first valve 3 on the described Bypass hose from front to back successively; first filter 4 and second valve 5.
This PET pelleter is closed the 3rd valve 8 and the 4th valve 9 with the bypass filter of recirculated water when working, open first valve 3 and second valve 5, and cooling water just feeds from first filter 4, enters at last in the pelleter 7; Because first filter 4 plays main filtration, when first filter 4 stops up or is out of order, only need close first valve 3 and second valve 5, open the 3rd valve 8 and the 4th valve 9, adopt second filter 6 to filter separately.Just can not influence the operate as normal of pelleter 7 when like this first filter 4 being cleared up, guarantee operating efficiency.
Claims (1)
1. a PET pelleter is with the bypass filter of recirculated water; comprise cooling water pipe (1); second filter (6) and pelleter (7); described cooling water pipe (1) links to each other with the import of second filter (6); the outlet of described second filter (6) links to each other with pelleter (7); described cooling water pipe (1) is provided with the 3rd valve (8) and the 4th valve (9); it is characterized in that: it also comprises Bypass hose (2); one end of described Bypass hose (2) is positioned on the cooling water pipe (1) of the 3rd valve (8) front end; the other end is positioned on the cooling water pipe (1) of the 4th valve (9) rear end, is provided with first valve (3) on the described Bypass hose from front to back successively; first filter (4) and second valve (5).
