Abstract
The invention discloses a waste oil regeneration device and method. The waste oil regeneration device comprises a precoating liquid storage tank, a precoating pump, a waste oil storage tank, an oil pump, a backflushing pump, a tubular filter and an oil collection tank. The waste oil regeneration method comprises the following steps that a, filtering aid is added into the precoating liquid storage tank to be evenly mixed with clean oil through a stirring machine; b, the precoating liquid enters the tubular filter to form a filtering aid layer by means of pressurization of the precoating pump; c, waste lubricating oil is filled into the tubular filter through the oil pump, impurities are blocked by the filtering aid layer, and the clean oil enters the oil collection tank through filtering media; and d, the clean oil in the oil collection tank reversely passes through the filtering media from an outlet of the tubular filter by means of the pressurization of the backflushing pump to enable the filtering aid and the impurities to be discharged out of the tubular filter. Under the premise that components of the existing lubricating oil are not changed, deflects and shortcomings in the existing waste oil regeneration device are overcome. By optimizing the recycling process of the existing device, oil quality and chromaticity are improved, and processing time is shortened.
Description
Technical field
The present invention relates to machine oil oil reclaimer and method in the mechanical processing process.
Background technology
Machine oil is widely used in the various mechanical means, is to reduce friction, and the liquid lubricant of protection machinery and workpiece mainly plays the effects such as cooling, lubricated, antirust, cleaning and sealing.Lubricating oil mainly is comprised of base oil and additive two portions, and wherein, the most basic lubrication is provided by base oil, and adding additive is in order to improve physicochemical property, to give new property to lubricating oil, satisfying higher requirement.Lubricating oil is in use owing to sneak into moisture, dust or be subjected to the effect of high temperature, high pressure, oxidation can produce the impurity such as multiple intermediate oxidation product, colloid, makes the lubricating oil quality variation and does discard processing.This year, along with petroleum resources day by day reduce and day by day strong to the cry of the attention of petroleum pollution problem and protection of the environment, countries in the world utilize work eleven to divide support to recovery and the purifying regeneration of waste lubricating oil.At present, the waste oil regeneration field is also relatively backward, and the lubricating oil that adopts settling process to separate is difficult to reach direct application requiring, and the treatment time is long, and regeneration efficiency is low.
Summary of the invention
The purpose of this invention is to provide a kind of new and effective, oil reclaimer and method that purification efficiency is high.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of oil reclaimer comprises pre-coating solution storage tank, precoating pump, waste oil storage tank, oil pump, backwashing pump, tubular filter and gathering tank.Described waste oil storage tank is provided with stirrer.The outlet of described waste oil storage tank connects the entrance of oil pump; The entrance of the outlet connecting pipe formula filter of described oil pump; The outlet of described pre-coating solution storage tank connects the entrance of precoating pump; Described precoating pump outlet connects the entrance of tubular filter; The outlet of described tubular filter connects the entrance of gathering tank; The outlet of the outlet connecting pipe formula filter of described backwashing pump; The outlet of described gathering tank connects the entrance of backwashing pump; The outlet of described gathering tank connects the absolute oil outlet conduit.
A kind of method of waste oil regeneration may further comprise the steps:
Add flocculating aids in the step a, pre-coating solution storage tank, evenly mix with stirrer with absolute oil;
Step b, pre-coating solution enter through the pressurization of precoating pump and form the flocculating aids layer in the tubular filter;
Step c, waste lubricating oil injects tubular filter through oil pump, and impurity is held back by the flocculating aids layer,
Absolute oil enters gathering tank by filtration medium;
Absolute oil oppositely passes through filtration medium by the backwashing pump supercharging from the tubular filter outlet in the steps d, gathering tank, and flocculating aids and impurity are discharged tubular filter.
Of the present inventionly do not changing existing lubricating oil family in principle, the defective that exists for present oil reclaimer and weakness are improved and are strengthened, and by optimizing the recovery technique of existing apparatus, improve oil quality and colourity, shorten the treatment time.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is the process flow sheet of oil reclaimer of the present invention.
Embodiment
As shown in Figure 1, specific embodiments of the invention, mainly may further comprise the steps: add carclazyte in the pre-coating solution storage tank, mixed 20～30 minutes with stirrer with absolute oil, pre-coating solution enters the flocculating aids layer that forms 5 mm thick in the tubular filter through the pressurization of precoating pump after evenly mixing.Waste lubricating oil injects tubular filter through oil pump, and impurity is held back by the flocculating aids layer, and absolute oil enters gathering tank by filtration medium.When reaching setting during 10 hours treatment times, absolute oil oppositely passes through filtration medium by the backwashing pump supercharging from the tubular filter outlet in the gathering tank, and flocculating aids and impurity are discharged tubular filter.It is lubricated that the interior absolute oil of gathering tank is directly used in mechanical means.
