Abstract
The invention discloses a constant temperature self-recovery type chemical degreasing method. The method comprises the following steps: injecting hot water into a degreasing chamber; injecting degreasing powder into the hot water in the degreasing chamber to form first solution; starting a stirrer to stir the first solution; enabling metal parts to enter the degreasing chamber to be soaked and degreased by the first solution to form second solution; taking away a certain amount of second solution in the degreasing chamber in a certain time and supplementing the same amount of first solution to the degreasing chamber in the same period of time; acquiring the first temperature of the solution in real time; and comparing the first temperature with the preset second temperature, and gradually extracting and heating the solution in the degreasing chamber and then circulating the solution back to the degreasing chamber when the first temperature is lower than the second temperature. The method has the beneficial effects that the wastewater after treatment is easy to treat; the degreasing effect is good; and the degreasing speed is high.
Description
Technical field
The present invention relates to a kind of constant temperature self-recovering type electrochemical deoiling method.
Background technology
Metalwork is being carried out surface treatment, for example before the zinc-plated processing, at first needing to remove the greasy dirt on metalwork surface, topmost way is electrochemical deoiling, at first, water is introduced in the degreasing tank, and is added degreasing powder; Then metalwork is immersed in the degreasing tank, by saponification reaction or emulsion reaction, thereby removes the greasy dirt on metalwork surface, yet its actual process is but comparatively slow, the poor effect of wipe oil is demanded urgently improving.
Summary of the invention
Problem for prior art exists the object of the invention is to propose a kind of constant temperature self-recovering type electrochemical deoiling method, and processed waste water is easy to process, deoiling effect is good, and it is fast to remove speed oil.
For achieving the above object, the present invention adopts following technical scheme:
A kind of constant temperature self-recovering type electrochemical deoiling method comprises:
To the indoor injection hot water of oil removing;
In the indoor described hot water of described oil removing, inject degreasing powder, form the first solution;
Starting agitator stirs;
It is described except the grease chamber that metalwork is entered, and described the first solution soaks described metalwork and decontamination is processed, and forms the second solution;
Take within a certain period of time indoor quantitative described the second solution of described oil removing away, within the identical time period, to described first solution of the indoor additional equivalent of described oil removing;
Gather in real time the first temperature of described solution;
Described the first temperature and the second default temperature are compared, when described the first temperature during less than described the second temperature, progressively extract the indoor solution heating of described oil removing after, loop back described except the grease chamber.
" it is described except the grease chamber that metalwork is entered, and be immersed in the described solution " makes the described grease chamber that removes be in sealed state afterwards.
Described except establishing thermal insulation layer in the grease chamber.
Based on disclosing of above technical scheme, the present invention possesses following beneficial effect:
The present invention is in actual mechanical process, except the grease chamber is in closed state, can effectively reduce heat loss, reduce energy consumption, in addition, the temperature except grease chamber's solution remains that the present invention adopts a working cycle, so that the indoor strength of solution of oil removing remains constant, help to guarantee deoiling effect and oil removal efficiency to the metalwork surface.
Embodiment
Further specify technical scheme of the present invention below by embodiment:
Embodiment 1
A kind of constant temperature self-recovering type electrochemical deoiling method comprises the steps:
S1, to the indoor injection hot water of oil removing.
Concrete: get one except the grease chamber, the indoor hot water inlet of establishing of oil removing, the hot water inlet place is provided with valve, and far-end connects the hot water supply equipment, is preferably boiler.
S2, to an amount of degreasing powder of the indoor injection of oil removing, at indoor formation the first solution of oil removing.
Concrete: degreasing powder can be by being opened in except another import adding in the grease chamber.
S3, startup agitator stir.
Concrete: the indoor agitator of establishing of oil removing, oil removing is outdoor to be controlled agitator work or quits work.
S4, metalwork is entered except the grease chamber, and be immersed in the first solution and process, the solution after the processing is called the second solution.
Concrete: the indoor opening for feed of establishing of oil removing, opening for feed can make metalwork enter thus.
S5, take indoor the second quantitative solution of oil removing away within a certain period of time, within the identical time period, to the first solution of the indoor additional equivalent of oil removing.
Concrete: in the electrochemical deoiling process, effective constituent is consumed gradually, for preventing oil removing process efficiency step-down deleterious, needs constantly to indoor first solution that replenishes of oil removing.
The first temperature of S6, collection solution.
Concrete: the indoor warming transport module of establishing of oil removing can gather the first temperature of solution in real time.
S7, first temperature that will collect and the second temperature of presetting compare, if detect the first temperature more than or equal to the second temperature, go to S5, when detecting the first temperature less than the second temperature, go to S7, until finish.
Concrete: the warming transport module is transferred to control chip with the first temperature, establish memory module, comparison module, control module in the control chip, comparison module is transferred the second temperature that is pre-stored in the memory module, and compare with the first temperature that is transferred to by the warming transport module, if the first temperature is more than or equal to the second temperature, then forward S5 to, if the first temperature less than the second temperature, then forwards S6 to.
S8, progressively extract the indoor solution of oil removing and heat, then, it is indoor that the solution circulated after the heating is injected oil removing.
Concrete: except the grease chamber is communicated with unit fixed on water pump suction, exit of pump connects the well heater import, control module control water pump and well heater work, water pump is from the indoor extraction solution of oil removing, and it is pumped in the well heater heat, and it is indoor through the injection of the solution circulated after heater heats oil removing, owing to adopt a kind of circulation pattern, make in the temperature that keeps the indoor solution of oil removing, cataclysm can not occur in the indoor temperature of oil removing, and the concentration of solution also remains, simultaneously, the process of water cycle also makes the aggravation of flowing in the solution, helps removing of metalwork surface and oil contaminant.
The present invention is in actual mechanical process, except the grease chamber is in closed state, can effectively reduce heat loss, reduce energy consumption, in addition, the temperature except grease chamber's solution remains that the present invention adopts a working cycle, so that the indoor strength of solution of oil removing remains constant, help to guarantee deoiling effect and oil removal efficiency to the metalwork surface.
The above; only be the better embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
