Description

Technical Field

[0001] This utility model relates to the field of raw oil filtration technology, specifically a raw oil filtration device. Background Technology

[0002] A feedstock oil filtration device is used to pre-treat unprocessed crude oil or primary oilseeds (such as vegetable oil, mineral oil, etc.). It is mainly used to remove solid impurities (such as silt, metal fragments), water, or other suspended matter to ensure the smooth progress of subsequent processing (such as refining, catalytic reactions). Its core is to improve the purity of the feedstock oil through physical filtration (such as filter screens, filter cloths, centrifugal separation) or adsorption technology (such as activated carbon) to avoid impurities damaging the equipment or affecting product quality.

[0003] For example, a raw oil filtration device with announcement number "CN204051133U" heats the raw oil to make it more fluid, improving filtration efficiency. Three layers of progressively finer mesh filters improve the quality of the filtered finished oil. Two sets of filters further increase filtration efficiency, and heating wires on the filters heat the oil within, improving its fluidity and reducing the heating load on the raw oil tank. However, in this device, the filter's position is relatively fixed. Over time, sludge and impurities accumulate inside the filter, making filter replacement and cleaning complex. Furthermore, these processes require machine shutdown, reducing operational efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems of fixed filter screen positions, which lead to the accumulation of sludge and impurities inside the filter screen during long-term use, making filter screen replacement and cleaning complicated. Furthermore, filter screen replacement and cleaning require machine shutdown, reducing work efficiency. Therefore, this invention proposes a raw oil filtration device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a raw oil filtration device, including a frame and a shell. The inner wall of the frame is fixedly connected to the shell in the middle. The shell is provided with a raw oil filtration adjustment structure. The lower end of the raw oil filtration adjustment structure is provided with a filter cartridge limiting structure. The upper end of the frame is fixedly connected to a pump body through a bracket.

[0007] Preferably, the raw oil filtration and adjustment structure includes a funnel, a motor is fixedly connected to the lower left side of the outer shell via a bracket, a first gear is fixedly connected to the end of the motor output shaft, the first gear's rotating shaft is rotatably connected to the outer shell via a bearing, the outer wall of the first gear meshes with a second gear, and the inner wall of the second gear is fixedly connected to the funnel.

[0008] Preferably, the outer wall of the funnel is rotatably connected to the outer shell via a sealed bearing.

[0009] Preferably, the first gear rotating shaft is rotatably connected to the housing via a bearing.

[0010] Preferably, the filter cartridge limiting structure includes a cylinder, the upper end of the outer wall of the cylinder is threadedly connected to a funnel, the outer wall of the cylinder is in contact with the funnel through a sealing gasket, the lower end of the outer wall of the cylinder is threadedly connected to a cover, a slide rod is fixedly connected to the upper end of the inner wall of the cover, the outer wall of the slide rod is slidably connected to a plurality of rings, the outer wall of the rings is in contact with the cylinder, and a filter screen is fixedly connected to the inner wall of the rings.

[0011] Preferably, the lower end of the pump body is fixedly connected to the vertical pipe.

[0012] Preferably, the outer wall of the vertical tube is fixedly connected to the frame.

[0013] The present invention provides a raw oil filtration device with the following advantages: through the raw oil filtration adjustment structure, the motor starts and drives the first gear to rotate in the outer shell through the bearing. The rotation of the first gear drives the second gear to rotate, and the second gear drives the funnel to rotate in the outer shell through the sealed bearing. The positions of the inner cavities on both sides of the funnel are swapped. Finally, the motor drives the two sets of filter screens to be swapped and adjusted. The position of the filter screen to be filtered can be adjusted without stopping the machine, thus avoiding affecting the working efficiency.

[0014] The filter cartridge is controlled by a limiting structure. The cartridge is rotated outward to disengage it from the funnel, and then the cover is rotated outward to disengage it from the cartridge. The cover is then pulled outward to disengage the slide rod from the multiple rings, thereby releasing the limiting of the rings. The multiple rings and the filter screen are then poured out of the cartridge and cleaned. The threaded connection between the cartridge and the cover makes it easier to disassemble the filter screen and facilitates cleaning and installation. Attached Figure Description

[0029] Working principle:

[0030] A raw oil filtration device

[0031] When it is necessary to filter the raw oil, first connect the pipe at the right end of the pump body 5 to the container containing the raw oil, then turn on the external power supply of the pump body 5, the pump body 5 starts to draw the raw oil and deliver it to the funnel 104 through the vertical pipe 6, and filter it through multiple filter screens 205 at the lower end of the funnel 104. The pore size of the multiple filter screens 205 gradually decreases from top to bottom, which can filter impurities of different sizes inside the raw oil. The filtered raw oil will flow to the material bucket at the lower end of the frame 3 for collection. When the filter screen 205 is blocked or has accumulated a lot of impurities, it needs to be cleaned.

[0032] When the external power supply of motor 101 is connected, motor 101 starts and drives the first gear 102 to rotate within the housing 4 via bearings. The rotation of the first gear 102 drives the second gear 103 to rotate, which in turn drives the funnel 104 to rotate within the housing 4 via sealed bearings. The positions of the inner cavities on both sides of the funnel 104 are switched. Since motor 101 is a servo motor that can rotate at a fixed angle and has a self-locking function, the funnel 104 can be positioned. By switching the position of the inner cavity of the funnel 104, the raw material oil can be filtered through the unused strainer 205 without stopping the working process.

[0033] After the clogged filter screen 205 is adjusted to the left end, rotate the cylinder 201 outward to disengage it from the funnel 104, then rotate the cover 202 outward to disengage it from the cylinder 201, and further pull out the cover 202 to disengage the slide rod 203 from the multiple rings 204, thereby releasing the restriction on the rings 204. Then, pour out the multiple rings 204 and the filter screen 205 from the inside of the cylinder 201 and clean them. After cleaning, arrange the multiple rings 204 according to the diameter of the filter screen 205 inside them, from largest to smallest, and insert them back onto the insertion rod 203 (e.g., large at the top, medium at the bottom).

[0034] Further rotate the cylinder 201 back to the lower end of the funnel 104. The elastic sealing gasket on the outer wall of the cylinder 201 can ensure relative sealing with the funnel 104. This movement can be used to disassemble and clean the filter screen 205. When adjustment is required again, the same working method is used to swap the positions of the funnel 104 and the cylinder 201 and disassemble and clean them.

[0035] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
