Embodiment one:
the recycling treatment equipment for the waste mineral oil is used as dangerous waste, and can effectively avoid the problem of environmental pollution caused by random discharge, so that resources are more fully utilized; because the waste mineral oil contains a large amount of large-particle impurities including various mineral waste residues, metal scraps, sand dust mixtures and the like, before further distillation and cracking treatment, sedimentation and filtration treatment are carried out firstly to fully remove the large-particle impurities in the waste mineral oil and realize oil residue separation, otherwise, the residue impurities are accumulated in a large amount in treatment equipment such as distillation and cracking, so that the separation of active ingredients in the waste mineral oil is influenced, the accumulation of oil dirt residues is also formed, the normal operation of the equipment is influenced, and the difficulty is increased for subsequent cleaning operation;
the existing oil-residue separation treatment operation is carried out on the waste mineral oil, and a filter screen 24 is generally directly adopted to filter and separate residues in the waste mineral oil; however, because the residue and the waste mineral oil are contacted for a long time, an oil residue mixture is formed, and is easily adsorbed on the filter screen 24 in the filtering process, the permeability of the filter screen 24 is affected, and the filtering efficiency of the waste mineral oil is further affected; therefore, in order to improve the filtering efficiency of the waste mineral oil, a filter pressing device or a filter residue scraping device is usually arranged on the upper side of the filter screen 24;
in practical application, workers find that because the oil residue adhesiveness is strong, the structure of the filter pressing device is too complex, the failure rate can be improved due to the adhesion accumulation of oil dirt, the later cleaning is difficult, the maintenance cost is high, and the filter pressing device is not suitable for recycling waste mineral oil in medium and small factories; the filter screen 24 is provided with a scraping and crushing device for scraping the filter residues, so that the surface of the filter screen 24 is required to be contacted and scraped, the oil residue content of the waste mineral oil is high, the cleaning times are high, the high-frequency scraping operation easily causes damage and leakage of the filter screen 24, and further the smooth performance of oil residue separation treatment is affected;
in order to effectively solve the problems, the application provides a waste mineral oil recycling treatment device, which is shown in figures 1-8 in the attached drawings of the specification, and comprises a filtering and separating module and a purifying module, wherein the filtering and separating module is used for filtering and separating oil residues of waste mineral oil, and the purifying module is used for purifying the filtered and separated waste mineral oil; specifically, the purification module comprises related matched equipment of distillation, cracking, condensation, separation and other processes common to the existing waste oil recovery processing equipment, and the waste mineral oil subjected to oil-residue separation processing is further separated and purified through the processes and the related matched equipment to remove invalid and harmful impurity components, so that the product fuel oil is obtained, and resource recovery is realized; the waste residue and sewage generated in the process are sent into corresponding treatment facilities for treatment, so that the environmental pollution is reduced;
the filtering separation module comprises: the sedimentation tank 1, the sidewall of the sedimentation tank 1 is provided with an oil inlet pipe 11, and the oil inlet pipe 11 inputs the recovered waste mineral oil to be treated into the sedimentation tank 1 through a connected oil pump; the filter box 2 is arranged on one side of the sedimentation tank 1 and is communicated with the interior of the sedimentation tank 1 through a filter pipe 21; the filter box 2 is used for realizing the separation operation of large-particle oil residues in the waste mineral oil, and then the separated waste mineral oil is sent to equipment corresponding to the next working procedure in the purification module through an oil outlet pipe 22 arranged at the bottom for further treatment;
the dispersing plate 23 is arranged in the filter tank 2 and is positioned at the lower side of the inlet of the filter pipe 21 and is connected with the side wall of the filter tank 2 through bolts, dispersing holes 231 are uniformly formed in the surface of the dispersing plate 23, the apertures of the dispersing holes 231 are larger and are only used for dispersing and concentrating inflow waste mineral oil, large-particle waste residues in the waste mineral oil do not influence smooth passing, and therefore accumulation of the waste residues on the upper side of the dispersing plate 23 is avoided, and normal operation of the dispersing plate 23 is influenced; maintenance personnel can open the box cover arranged at the top of the filter box 2 at regular time, and clean and maintain the components such as the dispersing plate 23 and the like in the filter box;
the filter screen 24 is arranged at the lower side of the dispersing plate 23, is made of elastic materials, and is fixedly connected with the inner wall of the filter box 2; the supporting plate 25, the supporting plate 25 is evenly arranged at the lower side of the filter screen 24, and the surface of the supporting plate 25 is evenly provided with filter holes 251; the vertical section of the supporting plate 25 is V-shaped, and the area of the filter screen 24 is larger than the area of the horizontal section inside the filter box 2, so that the filter screen 24 is in a loose state, and the corresponding part between the filter screen 24 and the middle of the supporting plate 25 can be embedded into the middle concave part of the supporting plate 25, so that the vertical section of the filter screen 24 is in a wave shape; the supporting plate 25 is an elastic plate, and a vibration device is arranged inside the supporting plate 25, wherein the vibration device can be a miniature vibration motor and is controlled by an external controller;
the specific working flow is as follows: waste mineral oil generated in the production process is collected and then is sent into the sedimentation tank 1 through the oil inlet pipe 11 for temporary storage; the waste mineral oil is kept stand in the sedimentation tank 1, and large-particle impurities in the waste mineral oil tend to be settled to the bottom of the sedimentation tank 1 under the action of gravity, so that preliminary oil-residue separation is realized; after the waste mineral oil is stood and accumulated to a certain degree, an oil pump connected with a filter pipe 21 is started at fixed time, so that the part, close to the upper side, of the sedimentation tank 1 is pumped into a filter box 2 through the filter pipe 21 for oil-residue separation and filtration treatment; waste impurities which are finally accumulated at the bottom of the sedimentation tank 1 can be extracted and then incinerated;
after the waste mineral oil entering the filter box 2 through the filter pipe 21 flows in from the pipe orifice, the waste mineral oil falls onto the dispersing plate 23 for a short time, then flows out through dispersing holes 231 uniformly formed in the dispersing plate 23, and the waste mineral oil intensively flowing in the process flows out from the dispersing holes 231 in a dispersing way, can more uniformly pass through the dispersing plate 23 and fall onto the filter screen 24 at the lower side, so that the waste mineral oil passing through the filter screen 24 is more uniformly distributed, and the filter screen 24 is fully utilized;
the downward waste mineral oil impacts the filter screen 24, so that the filter screen 24 is subjected to downward acting force, and the supporting plate 25 positioned on the lower side of the filter screen 24 plays an upward supporting role on the filter screen 24, so that excessive deformation of the filter screen 24 is limited, the pulling action of the connecting part of the edge of the filter screen 24 and the inner wall of the filter tank 2 is reduced, the integrity of the filter screen 24 in the working process is ensured, and the service life of the filter screen 24 is prolonged;
further, because the V-shaped supporting plate 25 is adopted, the filter screen 24 is embedded in the middle concave position of the supporting plate 25, the surface of the filter screen 24 is provided with continuously staggered convex and concave positions, and the vertical section is wavy; because the area of the filter screen 24 exceeds the horizontal cross-sectional area of the interior of the filter tank 2, the contact area of the wavy surface of the filter screen 24 and the waste mineral oil accumulated on the upper side is larger, and the waste mineral oil fully permeates and filters through the filter screen 24 to separate out residues; then the waste mineral oil and slag separation and filtration efficiency is improved by passing through the gaps between the supporting plates 25 or the filtering holes 251 arranged on the surfaces and falling to the bottom of the filter box 2 and leading the waste mineral oil and slag into the next process through the oil outlet pipe 22 for further treatment;
because the downward flowing waste mineral oil is concentrated to the concave part under the action of gravity, the downward flowing waste mineral oil contacts with the surfaces of the two sides of the concave part of the filter screen 24 and passes through after the residues are separated; in the process, the filtered residues are left at the bottom of the concave part, and the residues left after the filtering on the convex part of the upper surface of the filter screen 24 are driven to flow into the concave part and accumulate at the bottom of the concave part of the surface of the filter screen 24 as the waste mineral oil flows along the surface of the filter screen 24 on the upper side of the filter screen 24;
so that the residues separated by the filter screen 24 in the waste mineral oil are concentrated to the middle part of the concave part, thus ensuring that the content of the residues accumulated on the surfaces of other parts of the filter screen 24 is less, having less obstruction to the passage of the waste mineral oil and being capable of normally carrying out filtering work; thus, residues are concentrated to partial areas, most areas on the filter screen 24 can normally play a role in filtering, the continuous working time of the filter screen 24 can be effectively prolonged, the cleaning frequency of the filter screen 24 is reduced, the filtering effect of waste mineral oil is improved, the abrasion degree of the filter screen 24 caused by frequent cleaning is also reduced, and the service life of the filter screen 24 is prolonged;
further, the vibration device arranged in the supporting plate 25 can be started at fixed time when the passing rate of the filter screen 24 is reduced, and the vibration device vibrates in a small amplitude and high frequency and acts on the supporting plate 25, so that the elastic supporting plate 25 vibrates and acts on the contacted filter screen 24; under the vibration action of the filter screen 24, the residue impurities adhered to the surface are separated and fall off in an acceleration way, and flow into the bottom of the concave part of the filter screen 24 in a concentrated way under the flushing of flowing waste mineral oil, so that the normal operation of other parts on the filter screen 24 is ensured, and the continuous operation time of the filter screen 24 is further prolonged; when the filter box 2 is opened to clean the filter screen 24, the bottom of the concave part of the filter screen 24 is mainly cleaned in a concentrated manner, and the workload of the cleaning process is reduced, so that the filter screen 24 can be rapidly put into the secondary work, and the filtering efficiency of the waste mineral oil is improved.

further, pressing blocks 254 with tapered ends are uniformly arranged on the opposite surfaces of the pressing plates 252, and during the folding process of the pressing plates 252, the tapered ends of the pressing blocks 254 contact the filter screen 24 and concentrate and squeeze impurity residues in the middle; the concentrated acting force of the conical end part effectively breaks up the residues adhered to the concave part in a large block-shaped volume in the extrusion process, so that the impurity residues are broken and dispersed, and the blocking effect of the filtered waste mineral oil is reduced; the concentrated extrusion effect enables the waste mineral oil mixed in the oil residue mixture at the concave part to be further extruded and flows out through the filtering holes 251 at the gap part of the pressing block 254, so that the recovery of the waste mineral oil is more fully realized;
the end of the pressing block 254 is in contact with the lower surface of the filter screen 24, when vibration equipment arranged in the pressing plate 252 is started, the vibration of the pressing plate 252 acts on the filter screen 24 through the end of the pressing block 254, the end of the pressing block 254 repeatedly impacts the filter screen 24 at high frequency under the action of vibration, so that impurity residues adhered to the filter screen 24 positioned on two sides of a concave part are accelerated to fall off under the action of vibration and are gathered on a closed area 241 at the bottom, temporary collection is obtained, and the obstruction to separation and filtration of waste mineral oil is reduced;
