Description

Technical Field

[0001] This utility model relates to the field of waste mineral oil filtration technology, and in particular to a waste mineral oil recycling and filtration device. Background Technology

[0002] Mineral oils extracted and refined from petroleum, coal, and oil shale may have their original physical and chemical properties altered during mining, processing, and use, rendering them unusable. Waste mineral oils generated during production require centralized collection and treatment, necessitating the use of recycling and filtration devices.

[0003] The existing waste mineral oil recycling filter device (CN216259341U) can clean the filter screen frame by using a brush structure, thus avoiding clogging and improving filtration efficiency. However, when the filter screen becomes clogged, the machine needs to be stopped for cleaning, which forces the filtration process to be interrupted. This not only shortens the daily effective filtration time but also limits the daily processing capacity of waste mineral oil, affecting the overall recycling efficiency. Utility Model Content

[0009] The effect achieved by the above components is that by using the dual filters to work alternately, when one filter becomes clogged, the system can quickly switch to the other filter to continue filtering without stopping the machine to wait for cleaning, thus avoiding interruptions in the filtration process, effectively extending the daily effective filtration time, and increasing the daily processing capacity of waste mineral oil.

[0010] Preferably, a support frame is fixedly installed on one side surface of the recycling bin, a pump is fixedly installed on the surface of the support frame, a pumping pipe is fixedly installed at the input end of the pump, the end of the pumping pipe away from the pump is connected to the storage bin, and an oil drain pipe is fixedly installed at the output end of the pump, the end of the oil drain pipe away from the pump is connected to the discharge hopper.

With the oil drain pipe made of flexible hose, the hopper can be moved flexibly for thorough cleaning, avoiding residual oil from contaminating subsequent filtration.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0024] Reference Figure 1-4 As shown in this embodiment: a fixing device 3 is provided on one side surface of the vertical plate 210. The fixing device 3 includes an extension rod 31 fixedly installed on one side surface of the vertical plate 210. A movable plate 32 is slidably connected to the outer wall surface of the extension rod 31. A positioning rod 33 is fixedly installed on the surface of the movable plate 32. A positioning hole 34 matching the positioning rod 33 is opened on one side surface of the extension plate 211. A limiting plate 35 is fixedly installed on the end surface of the extension rod 31 away from the vertical plate 210. A spring 36 is fixedly installed between the limiting plate 35 and the movable plate 32. The elastic coefficient of the spring 36 is 10 N / mm, and the initial compression is 10 mm.

[0025] Working principle: When the device is needed, waste mineral oil is first injected into the storage tank 4 through the adding pipe 11 to ensure sufficient oil. Then, the extraction pump 6 is started, and the extraction pump 6 draws the waste mineral oil from the storage tank 4 into the drain pipe 8 through the extraction pipe 7. The oil is then transported to the discharge hopper 213 through the discharge pipe 214 at the bottom of the discharge hopper 213 and discharged to one of the filter screens 204 at the top of the recovery tank 1. After the oil is filtered by the filter screen 204, impurities are trapped, and the pure oil falls into the recovery tank 1. During the filtration process, if the filter screen 204 is found to have reduced filtration efficiency due to impurity accumulation, first shut down the extraction pump 6 to stop the oil supply; then start the motor 207, which drives the threaded rod 206 to rotate, causing the movable plate 209 to slide along the groove 208. The movable plate 209 drives the vertical plate 210, the extension plate 211, and the connecting rod 212 to move synchronously, ultimately moving the discharge hopper 213 horizontally to directly above another unblocked filter screen 204; after shutting down the motor 207, restart the extraction pump 6. The oil continues to be filtered through the new filter screen 204. At this time, the clogged filter screen 204 can be pulled out from the first mounting rail 201 and the second mounting rail 203 for cleaning, so that the filtration operation is uninterrupted and the recovery efficiency is improved. After the filtration operation is completed, the valve 10 on the discharge pipe 9 is opened to discharge and collect the filtered oil in the recovery box 1. If it is necessary to clean the discharge hopper 213, first slide the moving plate 32 to move it along the extension rod 31. While the moving plate 32 squeezes the spring 36, it drives the positioning rod 33 to disengage from the positioning hole 34, releasing the limit between the extension plate 211 and the vertical plate 210. Then, the extension plate 211 is pulled out from the vertical plate 210. Since the oil discharge pipe 8 is a flexible hose, the discharge hopper 213 can be flexibly pulled to a suitable position for cleaning to avoid residual oil contamination. After cleaning, the reverse steps are repeated to reset. Through the coordinated operation of the above structures, the device realizes continuous filtration of waste mineral oil, rapid switching of filter screen 204 and convenient maintenance of components, effectively solving the problem of filtration interruption in traditional devices.
