Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to an oil purification device based on adsorption filtration. Background Technology

[0002] Oils and fats are widely used in food, chemical, and pharmaceutical industries. Adsorption filtration is one of the core processes for oil and fat purification. However, existing adsorption filtration equipment generally suffers from problems such as low adsorbent utilization, insufficient filtration precision, and incomplete impurity removal, resulting in oil and fat purity that cannot meet the requirements of high-end applications. Furthermore, the equipment operates with low efficiency and high energy consumption. To address these pain points, it is urgent to develop a high-efficiency and precise adsorption filtration oil and fat purification equipment to improve the quality and production efficiency of oil and fat purification.

[0003] In existing technologies, traditional oil purification equipment often uses traditional filtration structures such as plate and frame filters and cartridge filters. These structures suffer from low filtration efficiency, long processing cycles, and high energy consumption due to the limited filtration area per unit volume. Furthermore, uneven flow field distribution can easily lead to filtration short circuits, resulting in an imbalance in the distribution of diatomaceous earth adsorbents and unstable adsorption and purification effects. In addition, the filter cloth lacks effective support and is prone to deformation and collapse, with a rapid clogging rate. This necessitates frequent shutdowns to replace filter media, leading to high equipment maintenance costs and poor continuous operation capability.

[0004] Therefore, an oil purification device based on adsorption filtration is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an oil purification device based on adsorption filtration, which can solve the problems of efficiency, energy consumption, maintenance and stability of existing equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil purification device based on adsorption filtration, comprising a filter tank, a honeycomb filtration mechanism movably connected to the inner side of the filter tank, an adjustment mechanism movably connected to the top of the inner side of the filter tank, the honeycomb filtration mechanism comprising multiple support plates, the multiple support plates being disposed on the inner side of the filter tank and evenly distributed longitudinally, each pair of support plates being fixedly connected to an irregularly shaped pipe, and a unit arrangement assembly movably connected to the inner side of the support plate.

[0007] Preferably, the adjusting mechanism includes a fixed plate, which is fixedly connected to the top of the inner side of the filter tank. A movable plate is rotatably connected to the top of the inner side of the filter tank, and the movable plate is located at the bottom of the fixed plate. Both the movable plate and the fixed plate have flow holes on their inner sides.

[0008] Preferably, a toothed ring is fixedly connected to the outer side of the movable disc.

[0009] Preferably, a servo motor is fixedly connected to the right side of the filter canister, and a drive gear is fixedly connected to the output end of the servo motor. The drive gear is meshed with the right side of the gear ring.

[0010] Preferably, the unit arrangement component includes multiple honeycomb channels, which are opened on the inner side of the support plate and are evenly distributed in a ring and penetrate the support plate. All inner walls of the honeycomb channels are fixedly connected with honeycomb support mesh.

[0011] Preferably, the honeycomb channel is embedded with a honeycomb mesh filter cloth.

[0012] Preferably, two irregularly shaped flow guides are fixedly connected to the inner side of the filter tank, and the two irregularly shaped flow guides are arranged symmetrically from top to bottom.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This application, by setting up a honeycomb filtration mechanism, adopts a longitudinally distributed circular support structure and an array of honeycomb filtration adsorption units, combined with irregularly shaped tubes to cover the non-filtration area and irregularly shaped flow guides to guide the flow. This not only significantly increases the filtration area per unit volume, but also optimizes the flow field uniformity to avoid short circuits. At the same time, the honeycomb support mesh provides stable support for the filter cloth. This effectively solves the problems of low filtration efficiency, high energy consumption, unstable adsorption and purification effect, easy deformation and clogging of filter cloth, high maintenance cost, and poor continuous operation capability of traditional oil purification equipment. It achieves the goal of centralized and efficient filtration and adsorption of oil, smooth feeding and discharging, and greatly improves purification efficiency and effect while reducing energy consumption and maintenance costs.

[0018] 2. This application incorporates an adjustment mechanism by adding a flow field adjustment structure consisting of a fixed disc, a movable disc, and a servo motor at the bottom of the filter tank's inlet pipe. By driving the movable disc to rotate, the overlapping flow holes of the two discs achieve periodic opening and closing and aperture changes. This precisely adapts to the flow field and flow rate requirements at different stages of oil purification, effectively alleviating the clogging problem caused by oil impact on the filter media, improving the uniformity and stability of adsorption filtration, further optimizing the flow field distribution, reducing energy consumption, and compensating for the potential shortcomings of relying solely on the filtration adsorption unit to adapt to dynamic purification needs, thus ensuring continuous and stable operation of the equipment.

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.

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] An oil purification device based on adsorption filtration includes a filter tank 1. A honeycomb filter mechanism 2 is movably connected to the inner side of the filter tank 1. An adjustment mechanism 3 is movably connected to the top of the inner side of the filter tank 1. The honeycomb filter mechanism 2 includes multiple support plates 21.

[0028] In this embodiment: a longitudinally distributed circular support structure is formed by support disks 21. This structure supports the array of filter adsorption units. Every two support disks 21 are connected by irregularly shaped tubes, and the irregularly shaped tubes cover the non-filter unit areas of the support disks 21.

The larger surface is a circular inlet with the cross-sectional size of the inner wall of the filter tank 1, and the smaller surface is the diameter that fits the shape of the filter unit inside the support disk 21. Through this unit arrangement component 23, the oil is concentrated and efficiently filtered and adsorbed, the flow field is uniform and there is no short circuit, the filter material is stable and not easily deformed, and the material inlet and outlet are smooth, which greatly improves the purification efficiency and effect and reduces energy consumption and maintenance costs.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the adjustment mechanism 3 includes a fixed plate 31, which is fixedly connected to the top of the inner side of the filter tank 1. A movable plate 32 is rotatably connected to the top of the inner side of the filter tank 1, and the movable plate 32 is located at the bottom of the fixed plate 31. Both the movable plate 32 and the fixed plate 31 have flow holes 33 on their inner sides.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, a toothed ring 34 is fixedly connected to the outer side of the movable disk 32.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, a servo motor 35 is fixedly connected to the right side of the filter tank 1, and a drive gear 36 is fixedly connected to the output end of the servo motor 35. The drive gear 36 is meshed with the right side of the gear ring 34.

[0032] In this embodiment: A flow field adjustment structure is provided at the bottom of the liquid inlet pipe 6 of the filter tank 1. This structure consists of two sets of circular plates with cross-sections consistent with the inner cavity of the filter tank 1.

The bottom movable disk 32 is rotatably connected to the inner wall of the filter tank 1 and is tightly fitted with the fixed disk 31. Both have annularly distributed flow holes 33 inside, which overlap and correspond to each other. The servo motor 35 on the outside of the filter tank 1 drives the drive gear 36 to drive the outer gear ring 34 of the movable disk 32, so that the movable disk 32 rotates and the flow holes 33 achieve periodic changes from small to large and from open to closed, thereby adapting to the flow field and flow rate requirements of different stages of oil purification, avoiding filter material impact clogging, improving the uniformity and stability of adsorption filtration, and reducing energy consumption.

[0033] Specifically, such as Figure 3 , Figure 4As shown, the unit arrangement component 23 includes multiple cellular channels 2301. The multiple cellular channels 2301 are opened on the inner side of the support plate 21 and are evenly distributed in a ring and penetrate the support plate 21. All inner walls of the cellular channels 2301 are fixedly connected with cellular support mesh 2302.

[0034] Specifically, such as Figure 3 , Figure 4 As shown, a honeycomb mesh filter cloth 2303 is embedded in the honeycomb channel 2301.

[0035] In this embodiment: the filter unit of the support plate 21 is composed of multiple annular arrays spliced ​​together and honeycomb channels 2301 that run through the support plate 21. Each honeycomb channel 2301 has a honeycomb support mesh 2302 installed on its six inner walls and a honeycomb mesh filter cloth 2303 embedded inside. Through directional flow guidance, vertical integration of high-density honeycomb filter adsorption units and shielding of non-filtering areas, concentrated and efficient filtration and adsorption of oil are achieved, the flow field is uniform and there is no short circuit, the filter material is stable and not easily deformed, and the material inlet and outlet are smooth, which greatly improves the purification efficiency and effect and reduces energy consumption and maintenance costs.

[0036] Specifically, such as Figure 2 As shown, two irregularly shaped flow guides 4 are fixedly connected to the inner side of the filter tank 1, and the two irregularly shaped flow guides 4 are arranged symmetrically from top to bottom. The two irregularly shaped flow guides 4 are fixedly connected to the opposite side of the top support plate 21 and the bottom support plate 21, respectively.

[0037] Specifically, such as Figure 2 As shown, a sealing ring 5 is fixedly connected to the outer side of the irregularly shaped flow guide 4, and the sealing ring 5 is located at the connection between the irregularly shaped flow guide 4 and the support plate 21.

[0038] In this embodiment, the liquid can be guided by the irregularly shaped flow guide 4 to prevent it from overflowing into the solid area of ​​the support plate 21, and the connection can be sealed by the sealing ring 5.

[0039] Specifically, such as Figure 1 , Figure 2 As shown, the top of the filter tank 1 is fixedly connected to the liquid inlet pipe 6.

[0040] Specifically, such as Figure 1 , Figure 2 As shown, a drain pipe 7 is fixedly connected to the bottom of the filter tank 1.

[0041] In this embodiment, the liquid is supplied and discharged through the inlet pipe 6 and the outlet pipe 7, respectively.

[0042] Working Principle: Traditional oil purification equipment often employs plate and frame or cartridge filter structures, which suffer from low filtration efficiency, long processing cycles, and high energy consumption due to limited filtration area per unit volume. Furthermore, uneven flow field distribution can easily lead to filtration short-circuiting, causing imbalances in the distribution of diatomaceous earth adsorbent and unstable adsorption and purification effects. Additionally, the filter cloth lacks effective support, making it prone to deformation and collapse, resulting in rapid clogging and frequent shutdowns for filter media replacement. This leads to high equipment maintenance costs and poor continuous operation. To avoid these issues, traditional filtration structures are no longer used. Instead, an array filtration adsorption unit supported by a longitudinally arranged circular support structure is employed. Its main component is a circular support structure composed of support disks 21, which are longitudinally distributed, with each pair of disks arranged longitudinally... Each support plate 21 is connected by a shaped tube, which covers the non-filter unit area of ​​the support plate 21 to allow for the connection of filter units in pairs. A shaped flow guide hood 4 is provided at the top and bottom of the top and bottom shaped tubes. The larger surface of the flow guide hood 4 is a circular inlet the size of the cross-section of the inner wall of the filter tank 1, and the smaller surface is an opening that conforms to the shape of the filter unit inside the support plate 21. This ensures that the flow can be directly and centrally guided to the interior of the top support plate 21, and the flow can be directly expanded and discharged from the bottom. The filter unit inside the support plate 21 is configured as follows: multiple honeycomb channels 2301 are provided in the filter unit area, each honeycomb channel 2301 penetrating the support plate 21 and arranged in a ring array. The filter is constructed by splicing components. Each honeycomb channel 2301 has a honeycomb support mesh 2302 installed on its six inner walls, and each honeycomb channel 2301 has a honeycomb filter cloth 2303 embedded inside. With this configuration, through directional flow guidance, vertical integration of high-density honeycomb filtration and adsorption units, and shielding of non-filtration areas, concentrated and efficient filtration and adsorption of oils are achieved. The flow field is uniform and short-circuited, the filter material is stable and not easily deformed, and the inlet and outlet are smooth. This significantly improves purification efficiency and effect, and reduces energy consumption and maintenance costs. Secondly, a flow field adjustment structure is set at the bottom of the liquid inlet pipe 6 of the filter tank 1. It is mainly composed of two sets of circular plates with the same cross-section as the inner cavity of the filter tank 1. The top support plate is fixedly connected to the inner wall of the filter tank 1 and separates it to form a shield. The bottom movable plate 32 is rotatably connected to the filter tank. The inner wall of the filter tank 1 is tightly fitted to the fixed plate 31. Both the fixed plate 31 and the movable plate 32 are provided with annularly distributed flow holes 33, which overlap and correspond to each other. By starting the servo motor 35 located on the outside of the filter tank 1, the drive gear 36 at the output end of the servo motor 35 can drive the outer gear ring 34 of the movable plate 32 to rotate. At this time, the overlapping flow holes 33 open and block each other, forming a periodic change from small to large and from open to closed. This allows for flexible adaptation to the flow field and flow requirements of different stages of oil purification, avoids filter media impact clogging, improves the uniformity and stability of adsorption filtration, and reduces energy consumption. In summary, this achieves the optimization of the adsorption filtration oil purification equipment.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
