Description

Technical Field

[0001] The utility model relates to the technical field of filtration, in particular to a basket filter for waste mineral oil production. Background Art

[0002] In recent years, with the promotion of the recycling and reuse industry, projects for waste mineral oil generated by industrial machinery production, ship dismantling, automobile maintenance and other industries have been carried out on a large scale across the country. Driven by energy shortages and economic interests, recycling into fuel oil and base oil is the most important way of utilization, and the waste mineral oil regeneration process has attracted people's attention.

[0003] Generally, the processing of waste mineral oil requires filtering the waste mineral oil and then settling it. Because the used waste mineral oil has more impurities and the impurity particles are relatively large, if it is processed directly, the impurities cannot be removed and subsequent processing cannot be carried out. Basket filters are mostly used for filtering waste mineral oil.

[0004] The basket filter includes a filter cartridge and a filter basket. Waste oil enters the filter cartridge for filtration, and the filtered waste oil flows out from the liquid outlet, while impurities are retained in the filter basket. Therefore, after a period of use, a large amount of impurities accumulate in the filter basket, so the filter basket needs to be taken out and cleaned regularly. On the one hand, the filter basket is heavily contaminated with oil and is inconvenient to clean. At the same time, stopping the machine for cleaning will lead to low work efficiency, or a dual-filtration parallel connection method is used, which in turn increases the overall cost of the equipment. Therefore, a basket filter that does not need to be cleaned frequently is needed. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. The described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In the related prior art, the basket filter includes a filter cartridge and a filter basket. Waste oil enters the filter cartridge for filtration, and the filtered waste oil flows out from the liquid outlet, while impurities are retained in the filter basket. Therefore, after a period of use, a large amount of impurities accumulate in the filter basket, so the filter basket needs to be taken out and cleaned regularly. On the one hand, the filter basket is heavily contaminated with oil and is inconvenient to clean. At the same time, stopping the machine for cleaning will lead to low work efficiency, or a dual-filtration parallel connection method is adopted, which in turn increases the overall cost of the equipment. Therefore, a basket filter that does not need to be cleaned frequently is needed.

[0025] In order to solve the problems existing in the related prior art, the utility model proposes a basket filter for waste mineral oil production. The principle and structure of the utility model are described in detail below in conjunction with the drawings and embodiments.

[0026] See also Figures 1 to 4 The utility model proposes a basket filter for waste mineral oil production, including a filter cartridge 1, which is cylindrical, with a liquid inlet 2 and a liquid outlet 3 on both sides respectively, the height of the liquid inlet 2 is higher than the height of the liquid outlet 3, an upper cover 4 is provided on the upper part of the filter cartridge 1, a filter basket 5 is provided inside the filter cartridge 1, the filter basket 5 is cylindrical, and the upper opening is inclined, and the height of the side close to the liquid inlet 2 is lower than the side close to the liquid outlet 3, a handle 6 is provided on the upper part of the filter basket 5, the bottom of the filter basket 5 is truncated, and a flushing pipe 7 is connected to the lower part, the upper part of the flushing pipe 7 is connected to the bottom of the filter basket 5, the lower part passes through the filter cartridge 1 and extends to the outside of the filter cartridge 1, and a valve 8 is provided at the end, specifically, the valve 8 is a CNC butterfly valve, and a differential pressure gauge 9 is provided at the liquid inlet 2 and the liquid outlet 3.

[0027] When in use, the filter is installed between the raw material storage tank and the sedimentation tank, so that the raw material flows into the sedimentation tank after being filtered by the filter, and the waste mineral oil flows into the filter cartridge 1 from the liquid inlet 2. The filter basket 5 filters the residual particles in the raw material and retains them in the filter basket 5. The filtered waste oil flows out from the liquid outlet 3 and flows into the sedimentation tank through the pipeline for sedimentation. After a period of use, impurities are deposited in the filter basket 5, and the lower valve 8 can be opened. At this time, part of the raw material flowing into the liquid inlet 2 continues to flow out from the liquid outlet 3 after filtration, and the other part will flow out from the bottom flushing pipe 7, and the residue deposited in the filter basket 5 will be flushed out and taken away, and then the valve 8 will be closed to achieve the flushing purpose. In this way, the number of times the internal filter basket 5 is taken out for cleaning can be reduced, thereby effectively improving work efficiency.

[0028] See also Figure 3 In order to ensure that the upper cover can be opened, a notch is provided at the same angle on the upper side of the filter cartridge 1 and the side of the upper cover 4. A bolt 10 is provided in the notch. The lower part of the bolt 10 is fixed to the side of the filter cartridge 1 through a pin 11 and a connecting ear 12. A lifting eye nut 13 is provided on the bolt 10. The lower part of the bolt 10 is sleeved on the pin 11 and can rotate around the pin 11. When it needs to be opened, the lifting eye nut 13 is rotated and the lifting eye nut 13 and the bolt 10 can be rotated around the pin 11 to the bottom of the upper cover 4. When it needs to be closed, the lifting eye nut 13 is rotated in the opposite direction to achieve a tightening effect.

[0029] See also Figure 4 , an annular rubber pad 14 is provided at the connection between the filter cartridge 1 and the upper cover 4, which can effectively improve the sealing effect and prevent leakage. The bottom of the filter basket 5 is connected to the flushing pipe 7 by a flange, and the flushing pipe 7 and the filter cartridge 1 are an integrated structure. The flushing pipe 7 and the filter cartridge are an integrated structure, which can effectively prevent bottom leakage on the one hand, and on the other hand, the connection between the filter basket 5 and the flushing pipe 7 can also effectively fix the filter basket to prevent the filter effect from being deteriorated due to misalignment.

[0030] See also Figure 2 and Figure 3 A group of connecting pieces 15 are fixed to the side of the filter cartridge 1, and a supporting frame 16 that can rotate around itself is provided on the connecting piece 15. The supporting frame 16 is in the shape of "7", and a collar 17 is provided at the end of the supporting frame 16. A lifting bolt 18 is provided in the collar 17. The lower part of the lifting bolt 18 is fixedly connected to the upper cover 4, and a lifting nut 19 is provided on the upper part. A rotating handle 20 is provided on the upper part of the lifting nut 19. When the upper cover 4 needs to be opened, the lifting nut 13 is loosened first, and then the rotating handle 20 is operated. The lifting nut 19 and the lifting bolt 18 are rotated relative to each other to drive the upper cover 4 to move upward, and then the lifting nut 13 and the bolt 10 are pushed to the side of the upper cover 4. At this time, the supporting frame 16 is rotated, and then the upper cover 4 is driven to rotate to one side and separate from the filter cartridge 1. In this way, there is no need to lift the upper cover 4 manually, and there is no need to worry about the upper cover 4 being placed on the ground or other places to cause oil pollution, which is more convenient to use.

[0031] Please continue reading Figure 1 After being used for a long time, some impurities with smaller particles will pass through the holes of the filter basket 5 but not flow into the sedimentation tank at the bottom of the filter cartridge 1. Therefore, a sewage outlet 21 is provided at the lower part of the filter cartridge 1 to discharge the impurities deposited at the bottom of the filter cartridge 1 regularly.

[0032] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
