Description
Technical field:
The present invention relates to many pumps independence conveying technology and equipment, be specifically related to a kind of from the terminal polymerization kettle to the die head many pumps independence conveying technology and equipment.
Background technology:
Like product divides the pipeline conveying technology, defective after adopting a pump manifold road output again: every branch pipeline pressure can not be controlled separately, divides the pipeline flow to change and can cause the main pipe rail pressure oscillation, influences each bar again and divides the pipeline pressure oscillation.
In normal productive process, if one or two unexpected undesired shutdown of production line, if would adopt present like product; Melt can't temporarily store; When strengthening pelleter output, will certainly cause the total pipe pressure of melt to rise, influence simultaneously divides pipe pressure; Pressure oscillation causes the quality variation of other production line film, even rupture of membranes is shut down.
Summary of the invention:
The purpose of this invention is to provide many pumps independence conveying technology and equipment from the terminal polymerization kettle to the die head; It can make the Melt Pump autostop of the production line of undesired shutdown; Unnecessary melt temporarily is stored in the terminal polymerization kettle; Control the liquid level of terminal polymerization kettle simultaneously through the output that strengthens pelleter, other production line still can continue to produce by original flow and pressure.
In order to solve the existing problem of background technology, the present invention adopts following technical scheme: it comprises terminal polymerization kettle 1, first Melt Pump 2, first die head 3, second Melt Pump 4, second die head 5, the 3rd Melt Pump 6, the 3rd die head 7, the 4th Melt Pump 8, the 4th die head 9, the 5th Melt Pump 10, pelleter 11; The discharging opening of terminal polymerization kettle 1 is connected with the charging aperture of first Melt Pump 2 through pipeline; The discharging opening of first Melt Pump 2 is connected with first die head 3 through pipeline; The discharging opening of terminal polymerization kettle 1 is connected with the charging aperture of second Melt Pump 4 through pipeline; The discharging opening of second Melt Pump 4 is connected with second die head 5 through pipeline, and the discharging opening of terminal polymerization kettle 1 is connected with the charging aperture of the 3rd Melt Pump 6 through pipeline, and the discharging opening of the 3rd Melt Pump 6 is connected with the 3rd die head 7 through pipeline; The discharging opening of terminal polymerization kettle 1 is connected with the charging aperture of the 4th Melt Pump 8 through pipeline; The discharging opening of the 4th Melt Pump 8 is connected with the 4th die head 9 through pipeline, and the discharging opening of terminal polymerization kettle 1 is connected with the charging aperture of the 5th Melt Pump 10 through pipeline, and the discharging opening of the 5th Melt Pump 10 is connected with pelleter through pipeline.
The present invention has following beneficial effect: the Melt Pump autostop that can make the production line of undesired shutdown; Unnecessary melt temporarily is stored in the terminal polymerization kettle; Control the liquid level of terminal polymerization kettle simultaneously through the output that strengthens pelleter, other production line still can continue to produce by original flow and pressure.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
Referring to Fig. 1, this specific embodiment adopts following technical scheme: it comprises terminal polymerization kettle 1, first Melt Pump 2, first die head 3, second Melt Pump 4, second die head 5, the 3rd Melt Pump 6, the 3rd die head 7, the 4th Melt Pump 8, the 4th die head 9, the 5th Melt Pump 10, pelleter 11; The discharging opening of terminal polymerization kettle 1 is connected with the charging aperture of first Melt Pump 2 through pipeline; The discharging opening of first Melt Pump 2 is connected with first die head 3 through pipeline; The discharging opening of terminal polymerization kettle 1 is connected with the charging aperture of second Melt Pump 4 through pipeline; The discharging opening of second Melt Pump 4 is connected with second die head 5 through pipeline, and the discharging opening of terminal polymerization kettle 1 is connected with the charging aperture of the 3rd Melt Pump 6 through pipeline, and the discharging opening of the 3rd Melt Pump 6 is connected with the 3rd die head 7 through pipeline; The discharging opening of terminal polymerization kettle 1 is connected with the charging aperture of the 4th Melt Pump 8 through pipeline; The discharging opening of the 4th Melt Pump 8 is connected with the 4th die head 9 through pipeline, and the discharging opening of terminal polymerization kettle 1 is connected with the charging aperture of the 5th Melt Pump 10 through pipeline, and the discharging opening of the 5th Melt Pump 10 is connected with pelleter 11 through pipeline.
Polyester fondant in this specific embodiment terminal polymerization kettle 1 is transported to separately die head or pelleter through discharging opening by the independent Melt Pump of every pipeline.
This specific embodiment is independent divide pipeline through separately independently frequency converter control separately, it is not separately controllable fundamentally to have solved every branch pipeline pressure; Terminal polymerization kettle 1 is as melt manufacturing cell, and inside is negative pressure, and simultaneously again as the melt storage element, capacity is big, is convenient to control the flow of branch pipeline, can control the liquid level of terminal polymerization kettle 1 through the output of adjustment pelleter; Every branch pipeline flow changes, and only influences final polycondensation autoclave liquid level, does not influence the pressure of branch pipeline, has fundamentally solved every branch pipeline flow and has changed, and causes the difficult problem of other minute pipeline pressure oscillation.
This specific embodiment can make the Melt Pump autostop of the production line of undesired shutdown; Unnecessary melt temporarily is stored in the terminal polymerization kettle; Control the liquid level of terminal polymerization kettle simultaneously through the output that strengthens pelleter, other production line still can continue to produce by original flow and pressure.
