DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0022] Referring to Figures 1-4 , the waste oil impurity removal filtering device comprises a filter cylinder 1, a filter screen plate 2 is fixedly installed on the inner side wall of the filter cylinder 1, the filter cylinder 1 inner side wall and the filter screen plate 2 are fixedly connected through a mounting mechanism, the filter cylinder 1 inner side wall is fixedly sleeved with a threaded sleeve ring block 14 and a limiting ring block 15, the threaded sleeve ring block 14 bottom and the limiting ring block 15 top are fixedly connected, the filter screen plate 2 outer side wall and the threaded sleeve ring block 14 inner side wall are slidingly connected, and the threaded sleeve ring block 14 inner side wall is threadedly sleeved with a threaded fixed sleeve ring block 16 capable of fixing the filter screen plate 2.

[0023] It is further explained that the mounting mechanism can ensure that the filter screen plate 2 does not displace due to the impact of waste oil or the vibration of the device during the filtering of waste oil, thereby ensuring the stability of the filtering process, and the mounting mode makes the replacement of the filter screen plate 2 simple. When the filter screen plate 2 is used for a period of time, it may need to be replaced due to reasons such as impurity blockage or damage.

[0024] As shown in Figure 1 and Figure 2 , a filtering mechanism is arranged on the inner top of the filter cylinder 1; the filtering mechanism comprises a heat-conducting mounting cylinder 3 fixedly installed on the inner top of the filter cylinder 1, a motor 4 fixedly installed on the inner side wall of the heat-conducting mounting cylinder 3, a fixed sleeve 5 fixedly sleeved with the output shaft of the motor 4, and two inclined pressing plates 6 fixedly installed on the fixed sleeve 5, the two inclined pressing plates 6 being centrally symmetrically distributed on the fixed sleeve 5, and the vertical distance between the inclined pressing plates 6 and the filter screen plate 2 gradually shortening from top to bottom.

[0025] It is further explained that the filtering mechanism on the inner top of the filter cylinder 1, the motor 4 drives the fixed sleeve 5 and the inclined pressing plates 6 to rotate, and the special distance between the inclined pressing plates 6 and the filter screen plate 2 can generate downward pressure and stirring effect on the waste oil, so as to make the impurities in the waste oil more fully contact the filter screen plate 2 and be intercepted, effectively improve the filtering efficiency and impurity removal effect, and make the filtered waste oil more pure.

[0026] As shown in Figure 1 and Figure 4As shown, the filter cartridge 1 top is provided with a feed inlet 10 and a ventilation opening 11, the filter cartridge 1 bottom is provided with a discharge outlet 12, the heat-conducting mounting cylinder 3 inner side wall and the ventilation opening 11 inner side wall are slidingly sleeved with the same connecting ring plate 13, and the heat-conducting mounting cylinder 3 inner side wall and the ventilation opening 11 inner side wall are connected with the connecting ring plate 13 outer side wall through a plurality of connecting bolts.

[0027] Further, the structure is more compact and stable through the connecting bolts, the ventilation and heat dissipation channel is ensured smooth, the internal working environment of the device is maintained, the overall structural strength of the device is improved, and the failure risk caused by loose connection of components is reduced.

[0028] As shown in Figure 1 , the heat-conducting mounting cylinder 3 is made of metal material with excellent heat conduction performance.

[0029] Further, the heat-conducting mounting cylinder 3 made of metal material can quickly dissipate the heat generated by the motor 4, which not only prevents the motor 4 from being damaged due to overheating and prolongs the service life of the motor 4, but also transmits the heat to the waste oil in the filter cartridge 1 through the heat-conducting mounting cylinder 3, ensuring that the waste oil flows in the entire filter mechanism in a suitable temperature environment, improving the stability and reliability of the device operation.

[0030] As shown in Figure 1 and Figure 2 , the connecting plate is fixedly installed on the inclined lower pressing plate 6, and the connecting plate and the inclined lower pressing plate 6 are connected through a plurality of limiting bolts.

[0031] Further, the limiting bolts enable the inclined lower pressing plate 6 to be better installed and disassembled.

[0032] As shown in Figure 1 , the inclined lower pressing plate 6 bottom is provided with a collecting mechanism, the collecting mechanism includes two collecting mesh frames 7, the inclined lower pressing plate 6 bottom is fixedly installed with a pointed scraper 8, the pointed scraper 8 bottom and the filter mesh plate 2 top are slidingly connected, the pointed scraper 8 is provided with a mounting opening 9, and the mounting opening 9 inner side wall and the collecting mesh frame 7 are connected through a plurality of mounting bolts.

[0033] Further, the collecting mechanism at the inclined lower pressing plate 6 bottom, the pointed scraper 8 can scrape off the impurities attached to the filter mesh plate 2 when the inclined lower pressing plate 6 rotates, the impurities fall into the collecting mesh frame 7, the collecting mesh frame 7 is conveniently disassembled through the mounting bolt connection, the impurities are conveniently collected and cleaned, the impurities are prevented from accumulating on the filter mesh plate 2 to affect the filtering performance, and the filter device is ensured to continuously and stably work.

[0034] The utility model can be described by the following operation mode to explain its function principle:

[0035] Feeding: Pour the waste oil that needs to be filtered into the inner space of the filter cylinder 1 from the feeding port 10 opened at the top of the filter cylinder 1.

[0036] Starting the motor 4: Turn on the motor 4 fixedly installed on the inner wall of the heat-conducting installation cylinder 3, and the motor 4 starts to operate, with its output shaft driving the fixed sleeve 5 to rotate.

[0037] Heat dissipation of the motor 4: When the motor 4 generates heat during operation, the heat generated by the motor 4 is quickly conducted to the heat-conducting installation cylinder 3 due to the fact that the heat-conducting installation cylinder 3 is made of metal material with excellent heat-conducting performance. The heat-conducting installation cylinder 3 has a heat transfer relationship with the waste oil in the filter cylinder 1, and the heat gradually dissipates from the heat-conducting installation cylinder 3 to the surrounding waste oil. With the transfer of heat, the temperature of the waste oil gradually rises, which to some extent helps to improve the flowability of the waste oil. Especially for some waste oil with large viscosity and poor flowability in low-temperature environment, moderate heating can make it flow more smoothly in the filter cylinder 1, better cooperate with the stirring and extrusion effect generated by the inclined lower pressing plate 6, and make the separation process of impurities and waste oil more efficient.

[0038] Filtering impurities: With the rotation of the fixed sleeve 5, the two inclined lower pressing plates 6 fixedly installed thereon rotate synchronously. Due to the fact that the vertical distance between the inclined lower pressing plate 6 and the filter screen plate 2 gradually shortens from top to bottom, the inclined lower pressing plate 6 produces downward pressure and stirring effect on the waste oil during rotation. The waste oil flows to the filter screen plate 2 under the action of pressure, and the impurities in the waste oil are intercepted by the filter screen plate 2. The pure waste oil passes through the filter screen plate 2 and collects at the bottom of the filter cylinder 1.

[0039] Cleaning impurities: When the inclined lower pressing plate 6 rotates, the sharp end scraper 8 at the bottom of the inclined lower pressing plate 6 also rotates. The bottom of the sharp end scraper 8 is slidingly connected with the top of the filter screen plate 2, which scrapes off the impurities attached to the filter screen plate 2. The scraped impurities fall into the collection mesh frame 7 through the installation port 9. The collection mesh frame 7 is connected with the sharp end scraper 8 through multiple bolts, which facilitates subsequent disassembly and cleaning of impurities.

[0040] Discharging: The filtered waste oil flows out through the discharge port 12 at the bottom of the filter cylinder 1, which can be collected for subsequent treatment or reuse.

[0041] Replacing the filter screen plate 2 (if necessary): When the filter screen plate 2 needs to be replaced due to blockage or damage, first unscrew the threaded fixed sleeve ring block 16 to disconnect it from the threaded connection with the threaded sleeve ring block 14. Then slide the filter screen plate 2 upwards along the inner wall of the threaded sleeve ring block 14 to remove it. Slide the new filter screen plate 2 along the inner wall of the threaded sleeve ring block 14 until it reaches the appropriate position. Then thread the threaded fixed sleeve ring block 16 onto the inner wall of the threaded sleeve ring block 14 and tighten it to fix the new filter screen plate 2, ensuring that the device can continue to operate normally.

[0042] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
