Abstract
The utility model relates to an automatic discharge device for a special-purpose filter, which is composed of a double-layer filtrate tank, a main vacuum pump, an auxiliary vacuum pump, etc. The upper layer of the filtrate tank is connected with the main vacuum pump, and the lower layer of the filtrate tank is connected with the auxiliary vacuum pump. When operating, the utility model controls the whole system to store liquid and discharge liquid through an upper spacing control switch and a lower spacing control switch in the lower layer, an electromagnetic valve connected to a pipeline and a pneumatic three-way valve. The automatic discharge device has simple structure and pipeline and low manufacture cost, and keeps high vacuum degree (-0.098 to 0.092MPa) in the process of manufacture so as to reach the purpose of saving energy; the utility model can improve the working condition and enhance the operational reliability.
Description
The utility model is the automatic draining device of extraordinary filter.
The pumping equipment of existing extraordinary filter is installed on the below of filter, for ease of discharge opeing, centrifugal water pump is installed on the filtrate tank below, whole device is by two filtrate tanks 1, vavuum pump 2, centrifugal pump 3, and part pneumatic operated valve, magnetic valve, liquid level gauge, pressure transmitter, Pressure gauge and pipeline composition, see accompanying drawing 1 for details.Lean on centrifugal water pump exterior liquid (pump is worked under negative pressure-0.095MPa condition) by force during this device work fully, so very high to the requirement of device mounting condition, the installation site of its centrifugal pump requires from filtrate tank leakage fluid dram vertical height h more than negative 3m.Simultaneously, this device construction is too huge, and pipeline is too complicated, and operation requires high.
The purpose of this utility model is to propose a kind of automatic draining device of novelty, and it is simple in structure, has reduced by a liquid bucket, simplified pipeline, removed expensive centrifugal water pump, can install on the level land, need not dig 3 meters on ground, therefore reduce production cost, be convenient to install, operate, keep in repair and safeguard.
By the automatic draining device of the extraordinary filter that the utility model proposes, the region of no pressure of its double-deck filtrate tank is by pipeline F
1, F
2Communicate with the gas-liquid distributing valve of filter, the region of no pressure links to each other with main vacuum pump by pipeline C, the drainage region of double-deck filtrate tank links to each other with secondary vavuum pump by pipeline D, there is pipeline E to link to each other between pipeline C and the D, magnetic valve is equipped with in the centre, on the pipeline D Pneumatic three-way valve is housed, and a upper limit gauge tap and lower limit gauge tap respectively are equipped with in double-deck filtrate tank drainage region upper and lower, the filtered fluid valve is equipped with in the two-layer centre of double-deck filtrate tank, and tapping valve is equipped with in the drainage region lower end.
Accompanying drawing 1 is the existing extraordinary structure pipeline schematic diagram of crossing liquid machine pumping equipment.
Accompanying drawing 2 is structure pipeline schematic diagrames of the present utility model.
Embodiment is explained in detail the utility model below in conjunction with accompanying drawing.
The utility model main body is double-deck filtrate tank 4, and the upper strata is region of no pressure A, and lower floor is drainage region B, filtered fluid valve 11 is housed between two-layer, on top, region of no pressure pipeline F is arranged
1, F
2The gas-liquid distributing valve 14 that leads to extraordinary filter has pipeline C to link to each other with main vacuum pump 5, and vacuum meter 13 topmost also is housed.Have pipeline D to link to each other with secondary vavuum pump 6 on the top of double-deck filtrate tank drainage region B, a upper limit gauge tap 9 and lower limit gauge tap 10 respectively are equipped with in the upper and lower of drainage region B, and drainage region B's is equipped with a tapping valve 12 bottom.A Pneumatic three-way valve 8 is housed on pipeline D, between pipeline C and pipeline D (pneumatic operated valve 8 front ends), connecting pipe E is housed, magnetic valve 7 is housed in the middle of it.
Principle of the present utility model mainly be to keep at work region of no pressure A have high vacuum (0.095～-0.090MPa), and under the situation that does not need to change in vacuum, make discharge opeing everything goes well with your work and carry out, accomplish automatic control.Its job order is as follows:
The liquid storage process: major and minor vavuum pump 5,6 is opened, filtered fluid in the drainage region B is discharged from, and when its liquid level dropped to lower limit gauge tap 10, it was open-minded to drive Pneumatic three-way valve 8, at this moment, under suction function, tapping valve 12 is closed automatically, when the B district reaches P=-0.092MPa, magnetic valve 7 is opened, because region of no pressure A communicates by pipeline E with drainage region B, so filtered fluid valve 11 is opened under the effect that filtrate is conducted oneself with dignity, and filtrate is continuously from pipeline F
1, F
2In region of no pressure A accumulates drainage region B again.
The discharge opeing process: major and minor vavuum pump 5,6 is opened, when the filtered fluid in the drainage region B accumulates liquid level when rising to upper limit gauge tap 9, drive magnetic valve 7 and close valve, threeway pneumatic operated valve 8 action relief B districts are communicated with atmosphere, at this moment, under A, B district differential pressure action, filtered fluid valve 11 closes, the negative pressure in A, B district drops to certain scope (about P=0.02MPa), under the effect of the filtrate deadweight of accumulating in drainage region B, tapping valve 12 is opened, and filtrate is discharged from, when the filtrate liquid level dropped to lower limit gauge tap 10, whole system began to carry out the liquid storage process again.
The utility model is compared with existing pumping equipment, has following advantages:
1, simple in structure, simplified pipeline, reduced some parts, be convenient to install, Operation and maintenance and maintenance do not need first water in operation. (former drainage system Must pour water earlier)
2, owing to the simplification of structure, whole manufacturing cost reduces about 40%.
3, reduced production cost, at first reduced by an expensive centrifugal water pump, and maintenance cost.Though increased a secondary vavuum pump, total installed power has still reduced by 71.9%, drop to 2.73KW, obvious energy conservation by the 9.73KW of former general power.
4, functional reliability is strong, because this device is not installed physical features and is limited, so do not need leakage fluid dram and liquid bucket discrepancy in elevation status requirement, the centrifugal pump that does not resemble former drainage system is worked under high condition of negative pressure, require very high and wearing and tearing pump aborning cause the turbid surplus decline of gas can cause the operating efficiency of pump to reduce to the turbid surplus of the gas of pump, this device solves this difficult problem, guaranteed the stationarity and the reliability of whole system work.
