Description

Technical Field

[0001] This utility model belongs to the technical field of filtration devices, specifically relating to a three-stage filtration device for frying oil. Background Technology

[0002] Frying oil refers to edible oils used for deep-frying and stir-frying food. When using frying oil that meets the quality standards, it can be reused several times after filtering out the oil residue.

[0003] Currently, different filtration devices are used to meet different precision requirements. For example, when the filtration precision is high, multi-stage filtration devices are usually used, which can effectively filter oil residue of different sizes and are easy to maintain and clean, and the filter screen can be replaced without stopping the machine.

[0004] For example, in the prior art, Chinese utility model patent with authorization announcement number CN218073322U discloses "a combined edible frying oil filter", which includes a filter box. The bottom of the filter box is equipped with casters and wheels.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] Please see Figures 1-5 The present invention provides the following technical solution: a three-stage filtration device for frying oil, including a filter box 1, and further including an oil injection funnel 2, a primary filter plate 3, a secondary filter plate 4, a tertiary filter plate 5, and an oil collection tank 6.

[0046] Furthermore, by Figure 1 As shown, in this embodiment, the oil filling funnel 2 is fixed to the top of the filter housing 1. The primary filter disc 3 is installed inside the filter housing 1 by a pull-out method. The secondary filter disc 4 is installed inside the filter housing 1 by a pull-out method and is located directly below the primary filter disc 3. The tertiary filter disc 5 is installed inside the filter housing 1 by a pull-out method and is located directly below the secondary filter disc 4. The oil collection tank 6 is placed inside the filter housing 1 and is located directly below the tertiary filter disc 5. With the above scheme, when in use, the frying oil to be filtered is injected through the oil filling funnel 2. Inside the filter housing 1, frying oil passes through the primary filter plate 3, the secondary filter plate 4, and the tertiary filter plate 5 from top to bottom, achieving three-stage filtration. This process removes oil residue of different sizes and makes cleaning the filter device easier after separating the oil residue. Furthermore, the filtration efficiency is high and clogging is not easily caused by the oil passing through the primary filter plate 3, the secondary filter plate 4, and the tertiary filter plate 5 from top to bottom. The collected oil residue can be cleaned by simply removing the primary filter plate 3, the secondary filter plate 4, and the tertiary filter plate 5 without the need for retrieval tools, making cleaning more convenient.

[0047] It should be noted that the pore size of the primary filter plate 3, the secondary filter plate 4, and the tertiary filter plate 5 gradually decreases. That is, when the frying oil passes through the primary filter plate 3, the secondary filter plate 4, and the tertiary filter plate 5, the larger oil residue is filtered through the primary filter plate 3 first, the medium-sized oil residue is filtered through the secondary filter plate 4, and finally the smaller oil residue is filtered through the tertiary filter plate 5.

[0048] In addition, the primary filter plate 3, the secondary filter plate 4, and the tertiary filter plate 5 are preferably made of stainless steel, which has high corrosion resistance and long service life.

[0049] Preferably, by Figure 1 As shown, this embodiment also includes a flow guide frame 7, which is fixed inside the filter housing 1 and located between the three-stage filter disc 5 and the oil collection tank 6. With the above solution, the flow guide frame 7 can reliably guide the edible oil during use, ensuring that the edible oil reliably enters the oil collection tank 6 below.

[0050] Preferably, by Figure 1 and Figure 3 As shown in this embodiment, a first-level guide slope 71 is processed at the top of the guide frame 7. After adopting the above scheme, the first-level guide slope 71 can guide the edible oil during use. If the top of the guide frame 7 is flat, it will easily create resistance to the edible oil and make it easy for the edible oil to accumulate. Therefore, designing the top of the guide frame 7 as a slope helps the edible oil to flow.

[0051] Optionally, by Figure 1 and Figure 2 As shown, this embodiment also includes: a C-shaped frame 10 and support bars 11. The C-shaped frame 10 is fixed inside the filter housing 1, and has a support groove 101 on the C-shaped frame 10. Support bars 11 are fixed on the end faces of the primary filter disc 3, the secondary filter disc 4, and the tertiary filter disc 5, and the support bars 11 are adapted to the support groove 101. With the above solution, in use, the cooperation of the C-shaped frame 10 and the support bars 11 realizes the pull-out installation of the primary filter disc 3, the secondary filter disc 4, and the tertiary filter disc 5, which facilitates the installation, use, disassembly, and cleaning of the primary filter disc 3, the secondary filter disc 4, and the tertiary filter disc 5.

[0052] It should be noted that in actual use, and to ensure the stability of the installation of the primary filter disc 3, the secondary filter disc 4, and the tertiary filter disc 5, the dimensions of the support strip 11 and the support groove 101 should be consistent. That is, when the support strip 11 is inserted into the support groove 101, the outer wall of the support strip 11 should abut against the inner wall of the support groove 101.

[0053] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, a second guide slope 102 is machined at the top of the C-shaped frame 10. With the above scheme, the design of the second guide slope 102 also helps the edible oil flow during use, ensuring that the edible frying oil can reliably pass through the first-stage filter plate 3, the second-stage filter plate 4 and the third-stage filter plate 5.

[0054] Preferably, by Figure 1 and Figure 4As shown, this embodiment also includes a cabinet door 12 and a handle 122. The cabinet door 12 is hinged to the front of the filter box 1, and the handle 122 is fixed to the free end of the cabinet door 12. With the above solution, when in use, the cabinet door 12 is closed during operation to prevent external dust from entering the filter box 1.

[0055] Optionally, by Figure 1 , Figure 4 and Figure 5 As shown, this embodiment also includes: a limiting block 13, a threaded rod 14, and a wing nut 15. The limiting block 13 is fixed to the free end of the cabinet door 12, and a notch 131 is machined on the limiting block 13. The threaded rod 14 is hinged to the outer wall of the filter box 1, and the threaded rod 14 passes through the notch 131. The wing nut 15 is installed on the protruding end of the threaded rod 14 by thread engagement. With the above solution, when the cabinet door 12 is closed, the threaded rod 14 is rotated so that the threaded rod 14 passes through the notch 131. Then, the wing nut 15 is tightened on the protruding end of the threaded rod 14 to ensure the stability of the cabinet door 12 after it is closed.

[0056] Preferably, by Figure 1 and Figure 4 As shown, this embodiment also includes a transparent observation window 121, which is embedded and fixed on the cabinet door 12. With the above solution, when in use, the status of the primary filter disc 3, the secondary filter disc 4, the tertiary filter disc 5 and the oil collection tank 6 can be seen through the designed transparent observation window 121 without opening the cabinet door 12.

[0057] Preferably, by Figure 1 and Figure 4 As shown, this embodiment also includes: four lockable casters 8, which are fixed diagonally at the four corners of the bottom surface of the filter housing 1. With the above solution, the filter device can be moved easily by the lockable casters 8 during use, making it convenient to use in different scenarios.

[0058] Preferably, by Figure 1 and Figure 4 As shown, this embodiment also includes a sealing cap 9, which is installed on the top of the oil filling funnel 2 by a threaded engagement. With the above solution, when not in use, the sealing cap 9 is installed on the top of the oil filling funnel 2 by a threaded engagement to prevent dust from passing through the oil filling funnel 2 and entering the filter box 1.

[0059] Components not described in detail in this article are existing technologies.

[0060] The working principle and usage process of this utility model: When using the three-stage filtration device for frying oil, the frying oil to be filtered is injected into the filter box 1 through the oil funnel 2. The frying oil passes through the first-stage filter plate 3, the second-stage filter plate 4 and the third-stage filter plate 5 from top to bottom to achieve three-stage filtration. It can filter out oil residue of different sizes, and the separation of oil residue makes it easier to clean the filtration device.

[0061] In addition, the frying oil passes through the first-stage filter plate 3, the second-stage filter plate 4 and the third-stage filter plate 5 from top to bottom, resulting in high filtration efficiency and less clogging. The collected oil residue can be cleaned by simply removing the first-stage filter plate 3, the second-stage filter plate 4 and the third-stage filter plate 5, without the need for scooping tools, making cleaning more convenient.

[0062] In another aspect of this utility model, the cabinet door 12 is closed during operation to prevent external dust from entering the filter box 1. After the cabinet door 12 is closed, the threaded rod 14 is rotated so that the threaded rod 14 passes through the notch 131. Then, the wing nut 15 is tightened on the protruding end of the threaded rod 14 to ensure the stability of the cabinet door 12 after it is closed.
