Specific embodiment
The utility model is further described with reference to embodiment and accompanying drawing.
As shown in figure 1, one kind carries out solvent collection and feed system based on negative-pressure cup, including solvent tanker 2, also include to bear
Pressure tank 1, reception basin 3 and pipeline pump 4, the top for receiving basin 3 are connected with solvent recovery pipe 11, and the bottom for receiving basin 3 leads to
Cross the first pipeline 7.1 to be connected with the bottom of negative-pressure cup 1, the top for receiving basin 3 is provided with the first evacuated tube 8.1, the first emptying
The 7th valve 5.7 is provided with pipe 8.1, and the two ends of the first pipeline 7.1 are respectively arranged with the 3rd valve 5.3 and the 4th valve 5.4,
The bottom of negative-pressure cup 1 is connected with solvent tanker 2 by the first feed pipe 6.1, is provided with the first valve on the first feed pipe 6.1
Door 5.1, the bottom of negative-pressure cup 1 is connected with the import of pipeline pump 4 by the second feed pipe 6.2, is set on the second feed pipe 6.2
The second valve 5.2 is equipped with, and the outlet of pipeline pump 4 is connected with second pipe 7.2, and the 5th valve is provided with second pipe 7.2
5.5, the outlet of pipeline pump 4 is connected with the top of solvent tanker 2 also by the 3rd pipeline 7.3, is provided with the 3rd pipeline 7.3
Six valves 5.6, the top of negative-pressure cup 1 are connected with the top of solvent tanker 2 by the second evacuated tube 8.2, in the second evacuated tube 8.2
Glass liquid level pipe 9 and the 8th valve 5.8 is provided with, the top of solvent tanker 2 is connected with material inlet pipe 10, is set on material inlet pipe 10
The tenth valve 5.10 is equipped with, the top of solvent tanker 2 is also connected with the 3rd evacuated tube 8.3, in the 3rd evacuated tube 8.3, is provided with
Nine valves 5.9.
Pipeline pump 4 is the solvent of solvent tanker 2 through the first feed pipe 6.1, negative-pressure cup 1, the second feed pipe 6.2 and
Two pipelines 7.2 are by solvent delivery to each reactor equipment needed for workshop.
4 type selecting of pipeline pump can select SL50 20, and the first feed pipe 6.1 and the second feed pipe 6.2 can select
The stainless steel tube of DN50mm, the first pipeline 7.1, second pipe 7.2 and the 3rd pipeline 7.3 can select the stainless steel tube of DN25mm,
The solvent of solvent tanker 2 passes through another pipeline pump（The utility model is not marked）Supplement through material inlet pipe 10.If only needing this
Work is without the need for negative-pressure cup 1.
Each reactor equipment is consumed through a series of numerous and diverse reactions, added solvent sub-fraction, most of molten
Agent is distilled to enter through solvent recovery pipe 11 by distillation still and receives basin 3.
In the prior art, the solvent for receiving the collection of basin 3 is needed through a membrane pump（Or a little pipeline pump）Defeated
It is sent to solvent tanker 2 to be recycled.In order to reduce equipment investment, reduce maintenance cost, the utilization rate of equipment is given full play to, this
In utility model, can be by membrane pump（Or small-power pipeline pump）Merge with pipeline pump 4, the work of membrane pump is completed by pipeline pump 4
Make（See Fig. 1）.
In practical application, receiving basin 3 is received by rhythm of production batch, so the volume for receiving basin 3 presses equipment
Reasonability type selecting less, receive basin 3 solvent for 2 volume of solvent tanker 1/4 1/3, while in a workshop may
There are two or more points and reception basin 3 is set, the reception basin 3 at each point is different with the distance of pipeline pump 4 and far and near
Differ.If by the requirement of pipeline pump 4, these are received basin 3 and all apply first pipeline 7.1 of DN50mm to be connected with pipeline pump 4, in
It is relatively costly, wastes excessive；And due to the quantity of solvent per secondary turn less, import caliber turns the material time when big can be fast and short,
The bad control of people, and caliber is big, increased stringing difficulty.If the first pipeline 7.1 for using DN25mm instead does pipeline, just overcome
Disadvantage mentioned above, but the sound of pipeline pump 4 can increase, and there is also sometimes de- liquid phenomenon and produce vibrations, time length are easily damaged
Bad machine is sealed, and shortens the service life of equipment, increases maintenance cost, increases staff labor intensity.But before pipeline pump 4 nearby
The negative-pressure cup 1 of one low capacity is installed（See Fig. 1 method of attachment）All problems can be resolved.
The type selecting of pipeline pump 4 is considered according to the following aspects.1st, the conveying capacity of liquid（That is flow）, 2,
Lift, 3, the property of liquid, 4, the arrangement of pipeline, it is most importantly the first two point.The aufbauprinciple of pipeline pump 4 be into and out of caliber
Difference, more than outlet, in the case that lift is not high, the two can be equal for import, and reducing mainly considers the loss of flow, and principle is
Identical into and out of piping flow for ensureing, certainly, it is ensured that import and export piping flow is identical, high in outlet pressure, caliber is certain
If, import is low because of pressure, so caliber necessarily will be a little bigger.
Connected with the stainless steel tube of DN50mm between negative-pressure cup 1 and pipeline pump 4 and most after enough space for maintenances are ensured
Amount is close, receives and is connected with first pipeline 7.1 of DN25mm between basin 3 and negative-pressure cup 1.This connection had both met pipeline pump
Requirement, can fully ensure that the normal work of pipeline pump 4, reached again save purpose, here it is negative-pressure cup 1 promote according to
According to.
If existing go to solvent tanker 2 the solvent for receiving basin 3, before pipeline pump 4 is started working, first close the first valve
The 5.1, second valve 5.2 of door, the 5th valve 5.5, the 6th valve 5.6, then open receive between basin 3 and negative-pressure cup 1 the 3rd
Valve 5.3 and the 4th valve 5.4, open the 8th valve 5.8 in the second evacuated tube 8.2 of the top of negative-pressure cup 1, allow reception basin
Stream is gone to negative-pressure cup 1 automatically by 3 solvent according to siphon principle of differential pressure, as negative-pressure cup 1 is shorter and smaller so holding very much than receiving basin 3
Easily fill, the 8th valve 5.8 is turned off when material seen by the glass liquid level pipe 9 of 1 top of negative-pressure cup, open the second valve 5.2
With the 6th valve 5.6, start pipeline pump 4, the solvent of negative-pressure cup 1 is through the second feed pipe the 6.2, the 3rd under the effect of pipeline pump 4
Pipeline 7.3 is entered and is recycled in solvent tanker 2, and after the solvent of negative-pressure cup 1 takes out as little as certain high-order, closed is negative
Negative pressure is formed in pressure tank 1, subsequently due to the principle of pressure reduction, receive basin 3 solvent automatically can cover through the first pipeline 7.1 negative
Pressure tank 1, is always on due to the 7th valve 5.7 of 3 top of reception basin, from completing to work, when reception 3 liquid of basin
During emptying, stop pipeline pump 4, turns material work and completes.
To during for workshop material, first close the second valve 5.2, the 3rd valve the 5.3, the 4th before pipeline pump 4 starts
Valve 5.4, the 5th valve 5.5, the 6th valve 5.6, then the first valve 5.1 is opened, open the 8th valve of 1 top of negative-pressure cup
5.8, allow the material of solvent tanker 2 negative-pressure cup 1 be flowed to through the first feed pipe, treat that thing seen by 1 top glass liquid level pipe of negative-pressure cup
The 8th valve 5.8 is turned off during material, then opens the second valve 5.2, the 5th valve 5.5, restart pipeline pump 4, then with above-mentioned
Principle, the material of solvent tanker 2 just go to workshop institute through the first feed pipe 6.1, the second feed pipe 6.2, second pipe 7.2
In the reactor for needing, required work is completed.
Specific embodiment described herein is only explanation for example to the utility model spirit.The utility model institute
Category those skilled in the art can make various modifications or supplement or using similar to described specific embodiment
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
