Description

Technical Field

[0001] This utility model belongs to the field of coated oil production technology, specifically relating to a coated oil filtration device. Background Technology

[0002] Coating oil usually refers to the substance used in fertilizer production to coat fertilizer granules. It is commonly known in the industry as "coating oil". Its professional name is anti-caking agent or loosening agent. There are two main types: vegetable oil and mineral oil. Vegetable oil is biodegradable in soil, but the fertilizer tends to have an odor after use, so it is used in smaller proportions. Mineral oil is mainly composed of high molecular weight hydrocarbons, which are more difficult to degrade in soil and pose a potential risk of soil pollution. However, because of its good anti-caking effect, it is used in larger proportions.

[0003] During the production, storage and use of coated oil, impurities often become mixed in for various reasons, affecting its performance and effectiveness. Therefore, it is necessary to filter it.

[0004] Traditional encapsulated oil filtration devices have many shortcomings, such as limited filtration precision, difficulty in effectively removing tiny impurities, low filtration efficiency leading to slow production processes, and difficulty in cleaning and maintenance, requiring a lot of manpower and time.

[0036] 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.

[0037] Please see Figures 1-5 The present invention provides the following technical solution: a coating oil filtration device, including a storage container 1, a top cover 2 mounted on the top of the storage container 1 by means of a flange, and a filtration mechanism 3 detachably mounted on the top cover 2. The filtration mechanism 3 includes: a filter box 31 with an inner cavity, an installation mechanism 32 for fixing the filter box 31 to the top cover 2, and a multi-stage filtration component 34 slidably disposed in the inner cavity for multi-stage filtration of the coating oil.

[0038] Furthermore, by Figures 1-3 As shown in this embodiment, the top of the filter box 31 is provided with an inlet 33 that communicates with the inner cavity, the top cover 2 is provided with an installation port 21 through which the filter box 31 passes, and the filter box 31 is provided with a pull-out port 311 for disassembling and assembling the multi-stage filtration components 34.

[0039] The storage container 1 is made of 304 stainless steel and has an outlet 11 at the bottom of the outer side of the storage container 1. A flange is provided on the outlet 11. The flange can be connected to a valve or connected to a centrifugal pump through a pipeline. The encapsulated oil stored in the storage container 1 can be directly taken out later to avoid the encapsulated oil from being mixed with impurities.

[0040] The top cover 2 is made of the same material as the storage container 1, and the thickness is designed as needed to ensure that it can stably support the multi-stage filter components 34 without deformation, and to ensure that the surface of the top cover 2 is flat, so as to ensure the sealing after installation.

[0041] The filter box 31 is made of food-grade PP material or stainless steel. The installation port 21 is larger than the filter box 31. A pull-out port 311 adapted to the multi-stage filtration component 34 is provided on one side of the filter box 31, which makes it easy to put in and take out the multi-stage filtration component 34.

[0042] Preferably, by Figures 1-3 As shown in this embodiment, the multi-stage filtration component 34 includes a filter screen plate 341, a filter cotton plate 342, and an activated carbon filter plate 343 in sequence along the direction of oil flow, and the three are arranged in parallel and spaced apart.

[0043] Among them, the filter plate 341 adopts "stainless steel mesh + stainless steel external frame", with a thickness of 3mm and a space of 50-100μm, and is used to filter large particulate impurities.

[0044] The filter cotton plate 342 is made of polyester fiber, with a thickness of 10mm and a pore size of 20-50μm, and is used to filter fine particles.

[0045] The activated carbon filter plate 343 is made of columnar activated carbon, with a thickness of 15mm and a pore size of 10-20μm. It is used to adsorb odors and ultrafine impurities.

[0046] Optionally, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the installation mechanism 32 includes: a first limiting plate 321 fixed to the outer wall of the filter box 31, a first threaded rod 322 fixed to the top surface of the top cover 2, and a first wing nut 323 installed on the protruding end of the first threaded rod 322 by threaded engagement. A first notch 3211 is machined on the first limiting plate 321, and the first threaded rod 322 passes through the first notch 3211. With the above solution, when the filter mechanism 3 needs to be installed, the filter box 31 is placed at the installation port 21 of the top cover 2, so that the first notch 3211 on the first limiting plate 321 fixed to the outer wall of the filter box 31 is aligned and the first threaded rod 322 fixed to the top surface of the top cover 2 is inserted. At this time, the first threaded rod 322 passes through the first notch 3211 and protrudes.

[0047] Subsequently, the first butterfly nut 323 is installed on the protruding end of the first threaded rod 322 by screwing it in, and the first butterfly nut 323 is tightened so that it fits tightly against the first limiting plate 321, thereby firmly fixing the filter box 31 on the top cover 2 and completing the installation of the filter mechanism 3.

[0048] When it is necessary to clean or replace the multi-stage filtration components 34 inside the filter box 31, simply loosen the first wing nut 323 in the reverse direction to separate it from the first limiting plate 321, and then remove the first notch 3211 on the first limiting plate 321 from the first threaded rod 322. The filter box 31 can then be removed from the top cover 2, and the multi-stage filtration components 34 can be operated. After the operation is completed, the filter box 31 can be fixed back onto the top cover 2 according to the above installation steps and can be used again.

[0049] The design of this installation mechanism 32, through the cooperation of the first limiting plate 321, the first threaded rod 322 and the first wing nut 323, enables quick assembly and disassembly between the filter box 31 and the top cover 2. This not only ensures the stability of the filtration mechanism 3 during operation, but also greatly simplifies the maintenance process of the multi-stage filtration components 34, saves maintenance time and labor costs, and ensures that the filtration device can continuously and efficiently perform oil filtration operations.

[0050] Preferably, by Figure 1 , Figure 2 and Figure 4As shown in this embodiment, there are four first threaded rods 322 and four first wing nuts 323 distributed at equal intervals along the circumference. With the above scheme, when in use, the four first threaded rods 322 and four wing nuts 323 distributed at equal intervals along the circumference can apply clamping force to the first limiting plate 321 from four symmetrical directions around the outer periphery of the filter box 31, so that a uniform and stable fixing effect is formed between the filter box 31 and the mounting port 21 of the top cover 2.

[0051] Compared to single-point or asymmetrical fixing methods, this method can effectively prevent the filter box 31 from tilting, shaking, or even shifting under conditions such as the impact of the enclosed oil flow or slight vibration of the equipment. This ensures the overall stability of the filter mechanism 3 and reduces problems such as misalignment of filter components and seal failure caused by loosening of the filter box 31.

[0052] Preferably, by Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, this embodiment also includes: a second limiting plate 4 fixed to one end of the multi-stage filter component 34, a second threaded rod 5 fixed to the outer wall of the filter box 31, and a second wing nut 6 installed on the protruding end of the second threaded rod 5 by thread engagement. A second notch 41 is machined on the second limiting plate 4, and the second threaded rod 5 passes through the second notch 41. With the above solution, when it is necessary to install the multi-stage filter component 34, the multi-stage filter component 34 is inserted into the inner cavity of the filter box 31 from the pull-out port 311 of the filter box 31, so that the second notch 41 on the second limiting plate 4 fixed to one end of the multi-stage filter component 34 is aligned and fitted onto the second threaded rod 5 fixed to the outer wall of the filter box 31. At this time, the second threaded rod 5 passes through the second notch 41 and protrudes.

[0053] Subsequently, the second wing nut 6 is installed on the extended end of the second threaded rod 5 by thread engagement, and the second wing nut 6 is tightened to make it fit tightly against the second limiting plate 4, thereby firmly fixing the multi-stage filter component 34 inside the filter box 31, preventing it from shifting or shaking during the oil flow process, and ensuring the stability of the filtration path.

[0054] When it is necessary to clean or replace the multi-stage filter component 34, simply loosen the second wing nut 6 in the opposite direction to separate it from the second limiting plate 4. Then, remove the second notch 41 on the second limiting plate 4 from the second threaded rod 5. The multi-stage filter component 34 can then be easily removed from the pull-out port 311 of the filter box 31. After cleaning or replacement, put the multi-stage filter component 34 back into the filter box 31 and fix it according to the above installation steps, and the filtration operation can continue.

[0055] This structural design, through the cooperation of the second limiting plate 4, the second threaded rod 5 and the second wing nut 6, enables quick assembly and disassembly between the multi-stage filter component 34 and the filter box 31. This not only ensures the stability of the multi-stage filter component 34 during the filtration process, but also simplifies maintenance operations, significantly shortens the time for cleaning or replacing filter components, and improves the overall efficiency of the device.

[0056] Preferably, by Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown in this embodiment, there are two symmetrically distributed second threaded rods 5 and second wing nuts 6. With the above scheme, when in use, the two symmetrically distributed second threaded rods 5 and second wing nuts 6 can apply a balanced clamping force from both sides of one end of the multi-stage filter component 34 to firmly fix the second limiting plate 4 to the outer wall of the filter box 31, thereby ensuring that the multi-stage filter component 34 is in a stable state in the inner cavity of the filter box 31.

[0057] Preferably, by Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, this embodiment also includes a rubber sealing frame 7, which is disposed between the second limiting plate 4 and the filter box 31. With the above solution, the rubber sealing frame 7 has good elasticity and sealing performance during use. When the second limiting plate 4 is pressed against the outer wall of the filter box 31 by the second wing nut 6, the rubber sealing frame 7 will be squeezed and deformed, thereby filling the tiny gap between the second limiting plate 4 and the filter box 31. This can effectively prevent the encapsulated oil in the filter box 31 from leaking from the connection between the two during the filtration process, avoiding waste of encapsulated oil and pollution to the surrounding environment of the equipment. At the same time, it also prevents external air, dust and other impurities from entering the interior of the filter box 31 through the gap, ensuring the cleanliness of the filtration environment and ensuring that the filtered encapsulated oil is not subject to secondary pollution.

[0058] Components not described in detail in this article are existing technologies.

[0059] The working principle and usage process of this utility model: The oil filtration device of this utility model pushes the multi-stage filtration components 34 (filter screen plate 341, filter cotton plate 342, activated carbon filter plate 343) into the inner cavity of the filter box 31 in sequence, aligning the second limiting plate 4 at one end with the second threaded rod 5 on the outer wall of the filter box 31, fitting the second notch 41 into the second threaded rod 5, embedding a rubber sealing frame 7 between the second limiting plate 4 and the filter box 31, and tightening the second butterfly nut 6, so that the rubber sealing frame 7 is deformed by compression, thereby achieving the sealing and fixing of the multi-stage filtration components 34;

[0060] Subsequently, the filter box 31 is placed in the mounting port 21 of the top cover 2, so that the first limiting plate 321 on the outer wall of the filter box 31 is fitted into the first threaded rod 322 on the top surface of the top cover 2 through the first notch 3211, and the four first wing nuts 323 are tightened to complete the fixing of the filter mechanism 3 and the top cover 2.

[0061] Finally, the top cover 2 is placed on top of the storage container 1 to complete the overall assembly;

[0062] The oil to be filtered is introduced into the inner cavity of the filter box 31 through the inlet 33 at the top of the filter box 31 via a pipe. Under the action of gravity and pressure, it flows along a preset path. First, it flows through the filter screen plate 341, which uses the 50-100μm pore size to intercept large particles of impurities (such as metal scraps, raw material clumps, etc.). Then, it passes through the filter cotton plate 342, which uses 20-50μm polyester fiber pores to further filter out small particles. Finally, it passes through the activated carbon filter plate 343, which uses 10-20μm activated carbon pores to adsorb ultrafine impurities and odors, completing the three-stage deep purification.

[0063] The purified oil flows into the storage container 1 through the bottom of the filter box 31. The storage container 1 temporarily stores the filtered oil. The outlet 11 at the bottom is controlled by a valve or centrifugal pump and can be discharged to the subsequent production process as needed to avoid oil residue in the container.

[0064] When the filtration efficiency decreases (e.g., the flow rate decreases), loosen the four first butterfly nuts 323 in the reverse direction and remove the filter box 31 from the top cover 2; loosen the second butterfly nut 6, remove the multi-stage filtration component 34, perform high-pressure rinsing on the filter screen 341, and replace the filter cotton plate 342 and activated carbon filter plate 343.

[0065] After cleaning, re-fix the multi-stage filter component 34 according to the assembly steps (ensure that the rubber sealing frame 7 is reset), put the filter box 31 back into the top cover 2, and tighten all nuts to resume filtration operation.

[0066] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
