Description

Technical Field

[0001] The utility model relates to the technical field of filtration, in particular to a filtration device for reducing the load of a filter element. Background Art

[0002] For the oil that has been used for a long time in mechanical equipment, impurities usually exist inside, such as dust, metal chips, water or chemical substances that may be mixed with the oil; the oil that has been used as lubricating oil, hydraulic fluid, heat transfer fluid, buoyancy fluid and other similar purposes can all be regarded as waste oil; when repairing an automobile, after the oil filter element filters the engine oil, the filtered waste oil needs to be further filtered. The existing filtering equipment usually has problems such as short service life of the filter element and low filtering efficiency. Content of the Utility Model

[0003] The purpose of the utility model is to provide a filtration device for reducing the load of a filter element aiming at the deficiencies of the prior art. By means of the cooperation of two connected fine filter element structures and multiple switch structures, the function of selectively using one of the fine filter elements or using them in series is realized, and the problems of short service life and low filtering efficiency are solved.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A filtration device for reducing the load of a filter element, including a machine body, and further including a coarse filter element arranged inside the machine body. The coarse filter element is connected with a coarse filter element inlet and a coarse filter element outlet. One end of a swing pump is connected to the coarse filter element outlet, the other end of the swing pump is connected to a heater, and two branch pipes are arranged at the other end of the heater. Each branch pipe communicates with a fine filter element, and a switch one for controlling the mixed oil to enter the fine filter element is fixedly arranged on each branch pipe.

[0005] Preferably, the bottoms of the two fine filter elements are communicated through a connecting pipe. A sewage outlet one is arranged at the bottom of each fine filter element, and a sewage switch one is arranged on each sewage outlet.

[0006] Preferably, a coarse filter element sewage outlet is arranged at the bottom of the coarse filter element, and a sewage switch two is arranged on the coarse filter element sewage outlet.

[0007] Preferably, an inlet switch is arranged at the coarse filter element inlet.

[0008] Preferably, the bottom end of the heater is fixedly connected with a heater support frame, and the heater support frame is fixedly connected with the inner bottom surface of the machine body.

[0009] Preferably, four moving wheels are arranged at the bottom of the machine body in a matrix distribution.

[0010] Preferably, a flow meter is connected to the swing pump.

[0011] Preferably, a sewage outlet of the swing pump is further provided on the pipeline connecting the end of the swing pump and the heater.

[0012] The beneficial effects of the present utility model are as follows:

[0013] (1) In the present utility model, an inlet switch is provided at the inlet of the coarse filter element. When the inlet switch is opened, waste oil enters the coarse filter element along the inlet switch. The filtered waste oil flows out through the outlet of the coarse filter element, passes through the swing pump, and flows to the heater. Since the coarse filter element is provided before the swing pump, some impurities with larger sizes (such as oxides, iron, copper, etc.) can be filtered, protecting the swing pump and increasing the service life of the swing pump. After the waste oil flows into the heater, the heater heats the waste oil to make the oil film thinner, improving the filtering effect of the subsequent filter element.

[0014] (2) By opening the sewage switch 1 in the present utility model, impurities accumulated inside the fine filter element during long-term use can be discharged, avoiding the influence of impurity accumulation on the filtering effect. When two fine filter elements are used in series, the filtering effect can be improved. At the same time, when only one of the filter elements is used alone, the usage diversity can be increased, avoiding the inability to perform the filtering function when a single filter element is damaged. The two fine filter elements can also be used in series to increase the filtering life of a single fine filter element.

[0015] (3) By providing a flow meter on the swing pump in the present utility model, the flow rate can be detected in real time. When the flow rate is too large, the flow rate can be adjusted by controlling the swing pump to avoid the influence of too large a flow rate on the heating effect of the heater.

[0016] In summary, the present utility model has the advantages of increasing the service life and filtering efficiency of the filter element. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Embodiment 1

[0023] Figures 1 to 2 Schematically shows a filtering device for reducing the load of a filter element of the present utility model, including a machine body, and further including a coarse filter element 2 disposed inside the machine body 1. The coarse filter element is connected with a coarse filter element inlet 21 and a coarse filter element outlet 22. One end of a swing pump 3 is connected to the coarse filter element outlet 22, and the other end of the swing pump 3 is connected to a heater 4. Two branch pipes 41 are provided at the other end of the heater 4. Each branch pipe 41 communicates with a fine filter element 5, and a switch 42 for controlling the mixed oil to enter the fine filter element is fixedly provided on each branch pipe 41.

[0024] In this embodiment, an inlet switch 211 is provided at the coarse filter element inlet 21. When the inlet switch 211 is opened, waste oil enters the coarse filter element 2 along the inlet switch 211, and the filtered waste oil flows out through the coarse filter element outlet 22. The filtered waste oil flows through the swing pump 3 and then flows to the heater 4. Since the coarse filter element 2 is provided before the swing pump 3, some impurities with larger sizes (such as oxides, iron, copper, etc.) can be filtered, protecting the swing pump 3 and increasing the service life of the swing pump 3. After the waste oil flows into the heater 4, the heater 4 heats the waste oil to make the oil film thinner, improving the filtering effect of the subsequent filter element.

[0025] Combined Figure 2 As shown, the bottoms of the two fine filter elements 5 are communicated through a connecting pipe 51. A drain port 52 is provided at the bottom of each fine filter element 5, a drain switch 53 is provided on each drain port 52, and a fine filter element discharge port 54 is further provided at the bottom of each fine filter element 5.

[0026] In this embodiment, opening the sewage discharge switch 53 can discharge the impurities accumulated inside the fine filter element 5 during long-term use, avoiding the influence of impurity accumulation on the filtering effect. When two fine filter elements 5 are used in series, close the switch 42 on one of the fine filter elements 5. At this time, the waste oil flows into from the other fine filter element 5, and after filtration, it enters the fine filter element 5 with the switch 41 closed through the connecting pipe 51. Subsequently, the waste oil is discharged through the fine filter element discharge port 54 for collection. For example, the connecting mode of the connecting pipe 51 should be connected to the top and bottom of the two fine filter elements 5 respectively, which can ensure that the waste oil can be fully filtered when passing through the second fine filter element 5. When both connecting pipes are connected to the bottom of the fine filter element 5, the fine filter element discharge port 54 needs to be opened to collect the waste liquid after the waste oil completely immerses the two fine filter elements 5. The waste oil has a better filtering effect after passing through the two fine filter elements 5. Of course, the two fine filter elements 5 can also be used separately. When used separately, close the switch 42 and the corresponding discharge port 54 on the unused fine filter element and the connecting pipe switch on the connecting pipe 51. Of course, the two fine filter elements 5 can also be used simultaneously. At this time, only the connecting pipe switch needs to be closed. When the two fine filter elements 5 are used simultaneously, the service life of each fine filter element 5 can be reduced.

[0027] Combined with Figure 1 As shown, a coarse filter element sewage discharge port 23 is provided at the bottom of the coarse filter element 2, and a sewage discharge switch 231 is provided on the coarse filter element sewage discharge port 23.

[0028] In this embodiment, opening the sewage discharge switch 231 can discharge various large-volume impurities stored inside the coarse filter element 2, saving the space inside the coarse filter element 2 and increasing the sewage discharge effect.

[0029] Combined with Figure 1 As shown, a heater support frame 41 is fixedly connected to the bottom end of the heater 4, and the heater support frame 41 is fixedly connected to the inner bottom surface of the machine body 1.

[0030] In this embodiment, the bottom support frame 41 can further improve the stability of the heating support frame 41. The heating support frame is bolted to both the machine body 1 and the heater 4. When the heater needs to be replaced after long-term use, it can be disassembled and replaced.

[0031] Combined with Figure 1 As shown, four moving wheels 11 are arranged in a matrix at the bottom of the machine body 1.

[0032] In this embodiment, when the moving wheels 11 are used, they can drive the machine body 1 to move, improving the moving efficiency.

[0033] Combined with Figure 1 As shown, a flow meter is connected to the swing pump 3.

[0034] In this embodiment, a flow meter is provided on the swing pump 3 to detect the flow rate in real time. When the flow rate is too large, the flow rate can be adjusted by controlling the swing pump 3 to avoid the heating effect of the heater 4 being affected by too large a flow rate.

[0035] Combined with Figure 1 As shown, a swing pump sewage discharge port 31 is also provided on the pipeline connecting the end of the swing pump 3 and the heater 4.

[0036] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
