Description

Technical Field

[0001] The utility model relates to the technical field of purification equipment, in particular to a filter tank. Background Art

[0002] At present, filter tanks are often used in the deep purification process of waste lubricating oil for decolorization, odor removal, removal of oxides and colloid asphalt. In traditional filter tanks, waste lubricating oil directly enters the filled adsorbent from the top for filtration under a certain pressure. The adsorbent produces pits due to the high-pressure impact from the lubricating oil, and serious deviation occurs during adsorption filtration, resulting in serious adsorbent compaction, low material effective utilization rate, and affecting the filtration speed. In addition, the filter material filling port is generally set at the top of the tank body, and the adsorbent material replacement, filling and unloading operations are inconvenient, which affects work efficiency and leads to low overall filtration efficiency.

[0003] Therefore, in view of the shortcomings of the above-mentioned scheme in actual production and implementation, it is revised and improved. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, a filter tank is specially provided to solve the problem of low filtration efficiency of the current filter tank.

[0004] In addition, the existing filter tanks have relatively simple functions, cannot filter according to usage requirements, are difficult to repair after being damaged, and have some functional or design defects as mentioned above. Utility Model Content

[0005] The utility model aims to provide a filter tank, which is used to solve the problem of low filtering efficiency of the existing filter tank.

[0006] The technical solution of the utility model is achieved in this way:

[0007] A filter tank comprises a tank body and a top cover which are connected to each other, wherein an oil inlet is arranged on the top of the top cover, an oil outlet is arranged on the bottom of the tank body, a material filling port and a material unloading port are arranged on the tank body, a support plate and a sieve plate are arranged in the tank body, the support plate has a large number of oil holes, a filter screen is arranged on the support plate, the sieve plate is located on the top of the filter screen, an adsorbent is filled between the filter screen and the sieve plate, a limiting member is arranged on the side wall of the tank body, the limiting member is used to limit and support the sieve plate, and a guide plate is arranged on the top of the sieve plate.

[0008] The top cover can be opened and closed quickly by adopting the rotating connection, and the limiting member can determine the setting position of the screen plate and support it.

[0009] As a preferred implementation, the tank body is rotatably connected to the top cover, and the tank body and the top cover are locked by bolts.

[0010] The locking bolt and the rotating connection are respectively arranged on two opposite surfaces, and matching ear plates are arranged on the tank body and the top cover to facilitate thread locking of the bolt.

[0011] Other locking parts can also be used for locking here, as long as it can be achieved.

[0012] As a preferred implementation, the limiting member is a plurality of uniform limiting blocks, and the limiting blocks are uniformly arranged along the circumference of the inner wall of the tank body.

[0013] As a preferred implementation, the limiting member is annular, and the limiting member and the tank body are an integrated structure.

[0014] The limiting member mainly limits the falling of the sieve plate in the longitudinal direction, and provides support for the sieve plate and positions it. As long as this can be achieved, two design schemes are provided above.

[0015] As a preferred implementation, the sieve plate is a stainless steel metal sieve plate, and the filter screen is a 1000-mesh filter screen.

[0016] As a preferred embodiment, a supporting frame matching with the tank body is disposed at the bottom of the tank body.

[0017] The filter tank can be used alone, which is more convenient.

[0018] Four adsorbent implementation plans are provided below, which can be selected as needed to perform directional filtration according to usage requirements to achieve better filtration effects.

[0019] As a preferred implementation, the adsorbent is fly ash.

[0020] Fly ash can be used in the pretreatment stage of waste oil regeneration. Fly ash can effectively absorb coloring substances such as heavy aromatics, colloids, asphaltene and other non-ideal components in waste lubricating oil, thereby greatly reducing the color of the oil. In addition, it can reduce polar substances such as cyclohexane acid and improve anti-emulsification performance.

[0021] As a preferred embodiment, the adsorbent is magnesium silicate.

[0022] Magnesium silicate can be used for deep purification of oil products. After the waste oil is adsorbed by magnesium silicate, non-ideal substances such as oxides, additives, colloids, asphaltene, etc. in the oil products are adsorbed, and the demulsification performance and foam characteristics of the oil products are significantly improved. The oil products after magnesium silicate adsorption can be used as base oil.

[0023] As a preferred embodiment, the adsorbent is white clay.

[0024] White clay can be used in the decolorization and neutralization stages of the waste lubricating oil regeneration process. White clay with a large specific surface area can effectively adsorb colloids, various organic acids and derived organic salts in the waste oil. Therefore, compared with the waste oil, the color of the recycled oil is greatly reduced and the decolorization effect is better.

[0025] As a preferred embodiment, the adsorbent is activated carbon.

[0026] Activated carbon is mainly used for odor removal and organic (oxidation, nitration and sulfation) and inorganic (heavy metal) pollutants in waste lubricating oil.

[0027] During operation, open the top cover and put in the stainless steel metal sieve plate to prevent the impact caused by the lubricating oil flowing through, which will cause deviation and affect the filtering effect. Open the material discharge port, lay a layer of 1000-mesh filter screen on the fixed plate, and then close the discharge port. Open the material filling port and fill a single homogeneous adsorbent (such as fly ash, magnesium silicate, kaolin, activated carbon, etc.). After filling to an appropriate level, compact the adsorbent to a certain extent. After the material filling is completed, close the material filling port.

[0028] When the oil flows in from the oil inlet, it passes through the guide plate to divert the oil to keep the flow rate of the lubricating oil stable and avoid the deviation caused by the violent impact of the lubricating oil on the adsorbent. After passing through the sieve plate, it is filtered by the adsorbent and the filter net, and finally passes through the oil hole to be discharged from the oil outlet.

[0029] Whether the adsorbent is invalid or not is determined based on the physical and chemical properties of the oil. If the adsorbent is invalid, the adsorbent is discharged from the material discharge port and refilled with new adsorbent.

[0030] The beneficial effects of the utility model are:

[0031] The utility model adds a guide plate below the oil inlet and a sieve plate above the adsorbent filling layer, which alleviates the impact load of the lubricating oil on the adsorbent and effectively avoids the deviation of the lubricating oil when filtering the adsorption layer. The material effective utilization rate is high and the filtering effect is good. It is not easy to form a hardening phenomenon, thereby ensuring the filtering efficiency.

[0032] The material filling port and the material unloading port of the utility model are arranged on the side wall of the tank body, so the addition and discharge operations of the adsorbent do not need to be performed from the top, the operation is convenient, the replacement and filling of the adsorbent material are more convenient, and the work efficiency is improved.

[0033] The adsorbent of the utility model can be replaced according to the use requirements, and the sieve plate can also be adaptively replaced according to different adsorbents. One can achieve different filtering effects according to the selection of the adsorbent, has better applicability, and broadens the filtering function.

[0034] The utility model has a simple structure, has no filter element structure, is not easy to be damaged, and the top can be opened, and a material filling port and a material unloading port are arranged on the side wall, so the internal maintenance is convenient and can be maintained at multiple angles.

[0035] In summary, the filter tank designed by the utility model patent is convenient for replacing materials and is not easy to be hardened, so the overall filtration efficiency is high, which solves the problem of low filtration efficiency of the current filter tank. In addition, the filtration performance can be changed as needed, which improves the single function and has better applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] like Figure 1 to Figure 4 As shown, a filter tank comprises a tank body 3 and a top cover 1 which are connected to each other, an oil inlet 7 is arranged on the top of the top cover 1, an oil outlet 6 is arranged on the bottom of the tank body 3, a material filling port 2 and a material unloading port 4 are arranged on the tank body 3, a support plate 13 and a sieve plate are arranged in the tank body 3, the support plate 13 has a large number of oil holes 14, a filter screen 12 is arranged on the support plate 13, the sieve plate is located on the top of the filter screen 12, an adsorbent 11 is filled between the filter screen 12 and the sieve plate, a limiting member 10 is arranged on the side wall of the tank body 3, the limiting member 10 is used to limit and support the sieve plate, and a guide plate 8 is arranged on the top of the sieve plate.

[0047] in, Figure 1 and Figure 2 Schematic diagrams showing the top cover in closed and open states are shown respectively.

[0048] The top cover 1 can be opened and closed quickly by adopting the rotating connection, and the limiting member 10 can determine the setting position of the sieve plate and support it.

[0049] The tank body 3 is rotatably connected to the top cover 1, and the tank body 3 and the top cover 1 are locked by bolts.

[0050] The locking bolt and the rotating connection are respectively arranged on two opposite surfaces, and matching ear plates are arranged on the tank body 3 and the top cover 1 to facilitate thread locking of the bolt.

[0051] Other locking parts can also be used for locking here, as long as it can be achieved.

[0052] The limiting member 10 is a plurality of uniform limiting blocks, and each limiting block is uniformly arranged along the circumference of the inner wall of the tank body 3 .

[0053] The limiting member 10 is annular, and the limiting member 10 and the tank body 3 are an integrated structure.

[0054] The limiting member 10 is mainly used to limit the falling of the sieve plate in the longitudinal direction, and to provide support and positioning for the sieve plate. As long as this can be achieved, two design solutions are provided above.

[0055] The sieve plate adopts a stainless steel metal sieve plate 9, and the filter screen 12 adopts a 1000-mesh filter screen 12.

[0056] A supporting frame 5 matching with the tank body 3 is arranged at the bottom thereof.

[0057] The filter tank can be used alone, which is more convenient.

[0058] Four adsorbent implementation plans are provided below, which can be selected as needed to perform directional filtration according to usage requirements to achieve better filtration effects.

[0059] The adsorbent is fly ash.

[0060] Fly ash can be used in the pretreatment stage of waste oil regeneration. Fly ash can effectively absorb coloring substances such as heavy aromatics, colloids, asphaltene and other non-ideal components in waste lubricating oil, thereby greatly reducing the color of the oil. In addition, it can reduce polar substances such as cyclohexane acid and improve anti-emulsification performance.

[0061] The adsorbent is magnesium silicate.

[0062] Magnesium silicate can be used for deep purification of oil products. After the waste oil is adsorbed by magnesium silicate, non-ideal substances such as oxides, additives, colloids, asphaltene, etc. in the oil products are adsorbed, and the demulsification performance and foam characteristics of the oil products are significantly improved. The oil products after magnesium silicate adsorption can be used as base oil.

[0063] The adsorbent is white clay.

[0064] White clay can be used in the decolorization and neutralization stages of the waste lubricating oil regeneration process. White clay with a large specific surface area can effectively adsorb colloids, various organic acids and derived organic salts in the waste oil. Therefore, compared with the waste oil, the color of the recycled oil is greatly reduced and the decolorization effect is better.

[0065] The adsorbent used is activated carbon.

[0066] Activated carbon is mainly used for odor removal and organic (oxidation, nitration and sulfation) and inorganic (heavy metal) pollutants in waste lubricating oil.

[0067] During operation, open the top cover 1 and put in the stainless steel metal sieve plate 9 to prevent the lubricating oil from causing impact and bias when flowing through, which will affect the filtering effect. Open the material port and discharge port, lay a layer of 1000-mesh filter screen 12 on the fixed plate, and then close the discharge port. Open the material filling port 2 and fill in a single homogeneous adsorbent 11 (such as fly ash, magnesium silicate, kaolin, activated carbon, etc.). After filling to an appropriate level, compact the adsorbent material to a certain extent. After the material filling is completed, close the material filling port 2.

[0068] When the oil flows in from the oil inlet 7, it passes through the guide plate 8 to divert the oil so as to keep the flow rate of the lubricating oil stable and avoid the deviation caused by the violent impact of the lubricating oil on the adsorbent 11. After passing through the sieve plate, the oil is filtered by the adsorbent 11 and the filter 12, and finally passes through the oil hole 14 to be discharged from the oil outlet 6.

[0069] Whether the adsorbent 11 is invalid or not is determined based on the physical and chemical properties of the oil product. If the adsorbent 11 is invalid, the adsorbent 11 is discharged from the material discharge port 4 and refilled with new adsorbent 11.

[0070] The beneficial effects of the utility model are:

[0071] The utility model adds a guide plate 8 below the oil inlet 7 and a sieve plate on the upper layer of the adsorbent 11 filling layer, which reduces the impact load of the lubricating oil on the adsorbent 11 and effectively avoids the deviation of the lubricating oil when filtering the adsorption layer. The material effective utilization rate is high and the filtering effect is good. It is not easy to form a hardening phenomenon, thereby ensuring the filtering efficiency.

[0072] The material filling port and the material discharge port 4 of the utility model are arranged on the side wall of the tank body 3, so the feeding and discharging operations of the adsorbent 11 do not need to be performed from the top, the operation is convenient, the material replacement and filling of the adsorbent 11 are more convenient, and the work efficiency is improved.

[0073] The adsorbent 11 of the utility model can be replaced according to the use requirements, and the sieve plate can also be adaptively replaced according to different adsorbents 11. One tank can achieve different filtering effects according to the selection of the adsorbent 11, has better applicability, and broadens the filtering function.

[0074] The utility model has a simple structure, has no filter element structure, is not easy to be damaged, and the top can be opened. A material filling port 2 and a material discharge port 4 are arranged on the side wall, so the internal maintenance is convenient and can be maintained at multiple angles.

[0075] In summary, the filter tank designed by the utility model patent is convenient for replacing materials and is not easy to be hardened, so the overall filtration efficiency is high, which solves the problem of low filtration efficiency of the current filter tank. In addition, the filtration performance can be changed as needed, which improves the single function and has better applicability.

[0076] The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement; when the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the utility model.
