Description

Technical Field

[0001] This application relates to the technical field of food processing, and in particular to an oil filtration device for a frying tank. Background Technology

[0002] In the food processing industry, frying tanks are commonly used equipment for frying food. However, during the use of frying tanks, food residue, moisture, and other impurities gradually accumulate in the oil, causing a large amount of contamination. These impurities not only reduce the quality of the oil, affecting the taste and appearance of the food, but also shorten the oil's lifespan, increasing maintenance costs and replacement frequency. Utility Model Content

[0003] In order to effectively filter oil, reduce oil residue, and improve oil recycling rate, this application provides an oil filtration device for frying tanks.

[0004] This application provides an oil filtration device for an frying tank, which adopts the following technical solution:

[0005] An oil filtration device for a frying tank includes a filtration tank, a slag collection frame, and a conveyor belt disposed within the filtration tank. The conveyor belt includes a conveyor mesh belt and a power assembly, the power assembly driving the conveyor mesh belt to rotate continuously. The conveyor mesh belt has a plurality of filter holes for oil to pass through. The filtration tank is provided with an inlet pipe, an outlet pipe, and an oil pump. One end of the oil pump is connected to the frying tank, and the other end is connected to the inlet pipe, which is located above the conveyor mesh belt. The slag collection frame is disposed on one side of the filtration tank, and one end of the conveyor belt extends out of the filtration tank and is located above the slag collection frame, allowing oil slag on the conveyor mesh belt to fall into the slag collection frame.

[0006] By adopting the above technical solution, the oil pump draws the oil from the frying tank to the filtration tank. The oil falls onto the conveyor belt and is filtered through the filter holes on the conveyor belt. The power unit drives the conveyor belt to rotate continuously, so that the oil residue can fall into the slag collection frame as the conveyor belt moves. This effectively improves the efficiency of oil filtration, reduces the trouble of manually cleaning oil residue, and ensures the cleanliness of the oil in the frying tank.

[0007] Optionally, the power assembly includes a drive roller, a driven roller, and a first motor. The drive roller is rotatably mounted on the outer wall of the filter tank, and the driven roller is rotatably mounted on the inner wall of the filter tank. The conveyor belt passes over the drive roller and the driven roller. The first motor is mounted on the filter tank, and the output shaft of the first motor is connected to the drive roller.

[0008] By adopting the above technical solution, the first motor drives the active roller to rotate, which in turn drives the conveyor belt to rotate continuously around the active roller and the driven roller.

[0009] Optionally, the power assembly further includes a guide roller rotatably disposed within the filter tank. The guide roller is positioned between the driving roller and the driven roller. After being guided by the guide roller, the conveyor belt is divided into a first filter surface and a second filter surface, with the first filter surface and the second filter surface forming an upward flare.

[0010] By adopting the above technical solution, the conveyor belt forms an upward flare. When filtration is not timely, the oil can remain in the concave part of the conveyor belt for continuous filtration, preventing the oil from flowing to both ends and affecting the filtration effect.

[0011] Optionally, it also includes an oil guiding assembly, which includes a central shaft rotatably mounted on the side wall of the filter tank, an oil guiding plate mounted on the central shaft, and a rotating component that drives the oil guiding plate to reciprocate along the central shaft. The oil guiding plate is located below the liquid inlet pipe, and the length direction of the central shaft is parallel to the length direction of the filter tank.

[0012] By adopting the above technical solution, the oil guiding assembly drives the oil guiding plate to reciprocate along the central axis through the rotating component, so as to evenly distribute the oil onto the conveyor belt, thereby improving the filtration effect and filtration efficiency.

[0013] Optionally, the rotating component includes a second motor disposed on the side wall of the filter tank, a rotating disk connected to the end of the output shaft of the second motor, an eccentric column disposed on the side wall of the rotating disk, and a connecting rod connecting the eccentric column and the oil guide plate, wherein the two ends of the connecting rod are rotatably connected to the eccentric column and the lower surface of the oil guide plate, respectively.

[0014] By adopting the above technical solution, the rotating component includes a second motor, a rotating disk, an eccentric column, and a connecting rod. The second motor drives the rotating disk to rotate, which in turn drives the eccentric column and the connecting rod to move, so that the oil guide plate can reciprocate along the central axis.

[0015] Optionally, it also includes a feeding assembly, which is disposed above the slag collection frame. The feeding assembly includes a mounting frame and a scraper. The mounting frame is disposed on the side wall of the filter tank, and the scraper is disposed on the mounting frame. The upper end of the scraper can abut against the lower surface of the conveyor belt.

[0016] By adopting the above technical solution, the feeding component scrapes off the oil residue on the lower surface of the conveyor belt with a scraper and drops it into the slag collection frame, which effectively reduces the oil residue on the lower surface of the conveyor belt, improves the filtration effect, and reduces the trouble of manual cleaning.

[0017] Optionally, the upper surface of the mounting bracket is provided with a first mounting groove for inserting the scraper plate, and a plurality of first bolts are provided on the side wall of the mounting bracket. The side wall of the mounting bracket is also provided with a threaded hole for threaded connection of the first bolts. The first bolts can be threaded through the threaded hole and abut against the side wall of the scraper plate.

[0018] By adopting the above technical solution, the position and angle of the scraper can be easily adjusted through the first mounting groove and the first bolt to adapt to conveyor belts of different thicknesses.

[0019] Optionally, the feeding assembly further includes a cleaning brush, and the upper surface of the mounting bracket is provided with a second mounting groove for mounting the cleaning brush. The side wall of the mounting bracket is also threaded with a plurality of second bolts for fixing the cleaning brush.

[0020] By adopting the above technical solution, the cleaning brush can further clean the residue in the filter holes of the conveyor belt, ensuring the cleanliness of the conveyor belt.

[0021] Optionally, a clearance hole is provided between the mounting bracket and the scraper and the cleaning brush to allow oil residue to pass through.

[0022] By adopting the above technical solution, clearance holes are opened between the mounting frame and the scraper and cleaning brush, so that the oil residue can pass smoothly and fall into the slag collection frame.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. Through the synergistic effect of the conveyor belt, power unit, guide roller and oil guiding assembly, rapid filtration and uniform distribution of oil are achieved, effectively improving filtration efficiency and cleanliness;

[0025] 2. The adjustable scraper mounting structure and cleaning brush configuration enable the device to adapt to conveyor belts of different thicknesses and effectively clean the residue on the underside of the conveyor belt, thus improving the applicability and flexibility of the device.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses an oil filtration device for a frying tank. (Refer to...) Figure 1 The oil filtration device includes a filter tank 1, a slag collection frame 2, and a conveyor belt 3 installed inside the filter tank 1. The filter tank 1 serves as the mounting point for various filtration devices, and the filtered oil can be temporarily stored within it. The filter tank 1 is a rectangular structure with a hollow interior and an open top. An inlet pipe 11 is embedded in the side wall along its long side at the top. An oil pump 13 is connected to the outer end of the inlet pipe 11, and the other end of the oil pump 13 is connected to the bottom of the frying tank 101. Thus, the oil in the frying tank 101 can be transported to the filter tank 1 for filtration via the oil pump 13. An outlet pipe 12 is embedded at the lower end of the filter tank 1 for extracting the filtered oil or directly returning it to the frying tank 101.

[0033] Reference Figure 1 and Figure 2 In this embodiment, the conveyor belt 3 includes a conveyor mesh belt 31 and a power assembly 4. The power assembly 4 drives the conveyor mesh belt to rotate continuously. The conveyor mesh belt 31 has a plurality of filter holes 311 evenly distributed for oil to pass through. An inlet pipe 11 is positioned above the conveyor mesh belt 31, allowing the oil to fall through the inlet pipe 11. After passing through the conveyor mesh belt 31, impurities such as oil residue carried in the oil are trapped on the conveyor mesh belt 31 and move forward continuously with it. A slag collection frame 2 is positioned on one side of the filter tank 1. A groove is formed on the side wall of the filter tank 1 at one end, where the short side is located. The conveyor mesh belt 31 extends out of the filter tank 1 from the groove and extends above the slag collection frame 2. When the conveyor mesh belt 31 rotates downwards at its end, impurities such as oil residue on the surface of the conveyor mesh belt 31 fall into the slag collection frame 2. This device effectively solves the problem of impurity accumulation in oil through continuous oil filtration and automatic collection of oil residue, improving oil quality and extending oil service life.

[0034] Reference Figure 1 and Figure 2 In this embodiment, the power assembly 4 specifically includes a drive roller 41, a driven roller 42, and a first motor 43. Specifically, the drive roller 41 is rotatably mounted on the outer wall of the filter tank 1. Preferably, two parallel supports can be provided at one end of the filter tank 1 with a groove, and the two ends of the drive roller 41 are rotatably connected to the supports via bearings or other means. The first motor 43 is mounted on the supports, and its output end is connected to the drive roller 41 via a coupling or other means. The driven roller 42 is rotatably mounted on the inner wall of the filter tank 1, and is located at the end away from the drive roller 41. The conveyor belt 31 winds around the drive roller 41 and the driven roller 42. Starting the first motor 43 drives the drive roller 41 to rotate, which in turn drives the conveyor belt 31 and the driven roller 42 to rotate, continuously filtering the oil and collecting the oil residue.

[0035] Reference Figure 2 and Figure 3 In an optional embodiment, to improve the filtration effect, the conveyor belt 31 can be shaped like a "V". Specifically, the power assembly 4 may also include a guide roller 44 rotatably disposed within the filter tank 1. The guide roller 44 is positioned between the drive roller 41 and the driven roller 42, and its horizontal position is lower than that of the drive roller 41 and the driven roller 42. After being guided by the guide roller 44, the upper surface of the conveyor belt 31 forms a first filter surface and a second filter surface, which together form an upward flare. With this structural arrangement, when the oil output is large, or when the surface of the conveyor belt 31 is partially blocked, and the oil cannot pass through in time, the oil can enter the lowest point along the slope for temporary storage and be filtered as the conveyor belt 31 moves. This avoids the problem of oil flowing along the conveyor belt 31 to the edge, resulting in poor filtration.

[0036] Specifically, two guide rollers 44 are spaced apart along the vertical direction. The conveyor belt 31 is divided into upper and lower layers. The lower guide roller 44 is located between the two conveyor belts 31, and the lower conveyor belt 31 abuts against and wraps around the lower guide roller 44. Multiple positioning rings are fixed on the outer side of the upper guide roller 44, and the upper conveyor belt 31 abuts against and wraps around the positioning rings. Thus, oil or oil residue on the surface of the conveyor belt 31 can pass through the gap between the upper guide roller 44 and the conveyor belt 31.

[0037] Reference Figure 2 and Figure 3In an optional embodiment, the oil filtration device further includes an oil guiding assembly 5. The oil guiding assembly 5 includes a central shaft 51 rotatably mounted on the side wall of the filter tank 1, an oil guiding plate 52 mounted on the central shaft 51, and a rotating component 53 that drives the oil guiding plate 52 to reciprocate along the central shaft 51. The length direction of the central shaft 51 is parallel to the length direction of the filter tank 1. The oil guiding plate 52 is located below the inlet pipe 11 and is a rectangular plate. Baffles can be provided on both sides of the oil guiding plate 52. Oil falls from the inlet pipe 11 onto the oil guiding plate 52 and then along the oil guiding plate 52 onto the conveyor belt 31. When the rotating component 53 drives the oil guiding plate 52 to reciprocate around the central shaft 51, it can change the position of the oil falling onto the conveyor belt 31, that is, it can guide the oil to be evenly distributed on the conveyor belt 31, preventing the oil from concentrating in one area, causing blockage, and affecting the filtration effect.

[0038] Reference Figure 2 and Figure 3 The rotating component 53 includes a second motor 531 mounted on the side wall of the filter tank 1, a rotating disk 532 coaxially connected to the end of the output shaft of the second motor 531, an eccentric column 533 fixed to the side wall of the rotating disk 532, and a connecting rod 534 connecting the eccentric column 533 and the oil guide plate 52. Both ends of the connecting rod 534 are rotatably connected to the eccentric column 533 and the lower surface of the oil guide plate 52, respectively. This design allows the oil guide plate 52 to reciprocate around the central axis 51, thereby better dispersing the oil.

[0039] Reference Figure 1 and Figure 4 In an optional embodiment, the oil filtration device further includes a feeding assembly 6. The feeding assembly 6 includes a mounting frame 61 and a scraper 62. One side of the mounting frame 61 is fixed to the side wall of the filter tank 1 by bolts or other means. The scraper 62 is detachably mounted on the mounting frame 61. The upper end of the scraper 62 can abut against the lower surface of the conveyor belt 31, and the upper end of the scraper 62 is preferably configured as a pointed structure, so that when the conveyor belt 31 passes by, the scraper 62 can assist in scraping off the oil residue on the surface of the conveyor belt 31, causing it to fall into the slag collection frame 2. The upper part of the scraper 62 can be made of an elastic material, such as rubber or silicone, which can effectively scrape off the oil residue without damaging the conveyor belt 31.

[0040] The upper surface of the mounting bracket 61 has a first mounting groove 611 for inserting the scraper plate 62. Several first bolts 612 are provided on the side wall of the mounting bracket 61, and corresponding threaded holes are also provided on the side wall for threaded connection of the first bolts 612. The first bolts 612 can be threaded through the threaded holes and abut against the side wall of the scraper plate 62. This design allows the scraper plate 62 to be easily disassembled and replaced, and its position can be adjusted up and down to ensure effective scraping.

[0041] Optionally, the feeding assembly 6 may also include a cleaning brush 63. A second mounting groove 613 for mounting the cleaning brush 63 is provided on the upper surface of the mounting frame 61. Several second bolts 614 for fixing the cleaning brush 63 are also threaded onto the side wall of the mounting frame 61. The cleaning brush 63 performs secondary cleaning of the conveyor belt 31, and the bristles on the cleaning brush 63 can penetrate deep into the filter holes 311, effectively preventing oil residue. A clearance hole 615 for oil residue to pass through is provided between the mounting frame 61 and the scraper 62 and the cleaning brush 63, i.e., between the first mounting groove 611 and the second mounting groove 613, reducing oil retention on the mounting frame 61.

[0042] The implementation principle of the oil filtration device for a frying tank according to this application embodiment is as follows: the oil fed into the filtration tank 1 is continuously filtered by the conveyor belt 3; simultaneously, the oil residue on the surface of the conveyor belt 31 is cleaned into the slag collection frame 2 by the scraper 62 and the cleaning brush 63. At the same time, the reciprocating motion of the oil guide plate 52 ensures that the oil is evenly distributed on the conveyor belt, improving the filtration effect. The entire process is highly automated, reduces manual intervention, and improves production efficiency and oil quality.

[0043] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
