Description

Intermittent type water-and-oil separator automatic discharge equipment

Technical field

The present invention relates to a kind of automatic discharge equipment of water-and-oil separator, especially relate to a kind of employing gravitational separation process, the automatic discharge equipment of the water-and-oil separator of service intermittent.

Background technology

For food and drink water-and-oil separator, oily water is step enters water-and-oil separator, sewage sedimentation under gravitational separation process effect, oil droplet floats, coalescent in long-pending oil groove, when coalescent to time a certain amount of, manually open valve, discharge long-pending oil, as shown in the case of application number CN201120201471 and CN201510075949.For many years, the automatic discharge equipment of this intermittent type water-and-oil separator also has multiple Development Scheme, but because resistant and integrity problem solve bad, can't be widely used; What current Application comparison was more is the method adopting mechanical frizing, and the complicated volume of device structure is large, inefficiency.

Summary of the invention

The object of the invention is to propose a kind of capacity transducer adopting measuring media to change and measure water-oil interface change, the switch controlling electrically operated valve realizes automatic oil draining, this instrument resistance to soiling is strong, the structure of water-and-oil separator can be made to become simply compact, the manufacturing cost of reduction equipment, improves reliability and the advance of equipment.

Technical solution of the present invention is: have an oil exit pipe in the side of long-pending oil groove, height at the bottom of the pipe of oil exit pipe is concordant or lower than height at the bottom of water outlet pipe, oil exit pipe there are motorized valve, dredge outlet and oil outlet, above long-pending oil groove, the instrument that is measured water-oil interface change is at least installed, can level install, also can at right angle setting.

Long-pending oil groove all communicates with air with intake-outlet, ignore the density difference of oil and water, when water-and-oil separator is in idle stationary state, liquid level can be considered contour everywhere, concordant with at the bottom of water outlet pipe, at this moment the water-oil interface in long-pending oil groove are minimum, after water-and-oil separator work for some time, in long-pending oil groove, grease is coalescent must be more, and water-oil interface are also lower, when the low lower limit to circuit configuration, the signal that instrument exports opens motorized valve after pilot circuit conversion.

When height at the bottom of oil outlet pipe is concordant or higher than water outlet pipe at the bottom of height time, need when having waited until that oily water enters separator again, under the effect of liquid level upward movement, flowed out by the valve opened higher than the long-pending oil at the bottom of oil exit pipe.When at the bottom of height at the bottom of oil outlet pipe is lower than water outlet pipe during height, the long-pending oil more than at the bottom of oil exit pipe enters oil exit pipe at the flows by action of deadweight, is flowed out, the long-pending oil below at the bottom of oil exit pipe by the valve opened, and is discharged under the effect that the water in-out port water surface falls after rise by jack-up coming; A pump can also be started and extract long-pending oil out.When oil is amassed in discharge, in long-pending oil groove, water-oil interface are also rising simultaneously, and during to the upper limit set, instrument output signal closes motorized valve after pilot circuit conversion, completes automatic oil draining and controls.

In order to increase the mobility of grease, need to arrange heating and temperature control unit, the work schedule of heating unit and motorized valve, is set by pilot circuit.

Instrument adopts the capacity transducer technology of measuring media change, and potential electrode, with oily water insulation, has good resistance to soiling and job stability.

In order to ensure the unimpeded of oil exit pipe, being provided with the dredge outlet be made up of plug, cover plate or valve etc. above oil exit pipe, can easily opening in routine use and clear up oil-drain pipe, preventing dirt from blocking.

Accompanying drawing explanation

Fig. 1: structural representation of the present invention.

In Fig. 1: (1) amasss oil groove, (2) heating temperature control device, (3) oil exit pipe, (4) instrument, (5) motorized valve, (6) oil outlet, (7) dredge outlet, A: liquid level is high, B: high at the bottom of oil discharge outlet pipe, C: upper limit, D: lower limit, E: water-oil interface.

Embodiment

As shown in Figure 1, oil exit pipe (3) is had in the side of long-pending oil groove (1), oil exit pipe (3) there is motorized valve (5), there are oil outlet (6) and dredge outlet (7), heating temperature control device (2) is had in the bottom of long-pending oil groove, at least installing one in long-pending oil groove (1) adopts the instrument (4) of measuring media change technique to measure water-oil interface change, when water-and-oil separator is in static working order, water does not flow into and does not flow out yet, height approximately equal at the bottom of fuel head and rising pipe, be positioned at A, after work for some time, grease is built up more and more thicker in long-pending oil groove (1), water-oil interface E moves down gradually, when arriving the lower limit D of circuit configuration, instrument (4) output signal is become valve opening signal by control circuit conversion, pilot circuit is according to the sequential of setting, first start heating temperature control device (2) work, then heating is stopped, open motorized valve (5), long-pending oil flows out from oil exit pipe (3), through motorized valve (5) and oil outlet (6), flow in the container of charge of oil.

During oil extraction, long-pending oil higher than B enters oil exit pipe (3) at the flows by action of deadweight, long-pending oil groove (1) is flowed out by the motorized valve (5) opened, liquid level A is caused to decline, and water in-out port liquid level A also can and then decline, the volume declined flows into the long-pending oil body accumulated amount of long-pending oil groove (1) interior jack-up lower than B, is also entered oil exit pipe (3) at the flows by action of deadweight by the long-pending oil of jack-up, flows out long-pending oil groove (1) by the motorized valve (5) opened.

After long-pending oil flows out long-pending oil groove (1), water in-out port water surface falling amount supplement enter the promotion of long-pending oil groove (1) under, water-oil interface E starts to rise, when arriving upper limit C, instrument (4) output signal converts to through pilot circuit and closes valve control output, close motorized valve (5), complete automatic oil draining work.

The grease adhesion separated is very strong, and also with impurity, easily oil exit pipe (3) blocking, when routine use is safeguarded, regularly open dredge outlet (7), the greasy filth dirt that cleaning oil exit pipe (3) is adhered to, support equipment normally works.

Automatic discharge equipment improves the performance of intermittent type water-and-oil separator, and structure is simple, and reliable operation, can reduce costs, and the competitive power of improving product facilitates the use of client, promotes the technical progress of industry.
