Description

Technical Field

[0001] This utility model relates to the technical field of oil purification equipment, specifically an offline integrated filtration and purification device. Background Technology

[0002] A stretching oil purification system is a device specifically designed to treat oil contaminants generated during the stretching process. It uses physical and chemical methods to separate, filter, dehydrate, and decolorize impurities deposited in the stretching oil. By effectively purifying and recovering the stretching oil, clean stretching oil is returned for reuse in equipment, reducing waste and improving product quality. Stretching oil purification systems are widely used in industries such as fiber, plastics, and rubber.

[0003] Patent (CN218280871U) discloses a vacuum oil filter, relating to the field of vacuum oil filter structure technology. It addresses the problem of existing vacuum oil filters' inconvenient and rapid oil filtration, resulting in low working efficiency. The vacuum oil filter body is mounted on top of a movable mounting frame. A sealing cover is mounted on top of the vacuum oil filter body, and an exhaust seat is mounted on the upper end of the sealing cover. A liquid level sensor is mounted on one side of the outer wall of the vacuum oil filter body, and a feed seat is located on the other side of the outer wall. A discharge seat is located at the lower end of the vacuum oil filter body, and a second filter is mounted below the discharge seat. A connecting pipe is mounted on one side of the second filter, and a circulation pump is mounted at one end of the connecting pipe. A first return pipe is mounted above the circulation pump, and a solenoid three-way valve is mounted above the first return pipe. A second return pipe is mounted above the solenoid three-way valve, and a transport pipe is mounted on one side of the solenoid three-way valve.

[0004] The vacuum oil filtration machine described in the aforementioned patent document uses a heating jacket on the outer wall of the vacuum tank to heat the stretching oil inside. The stretching oil inside the vacuum tank near the tank wall heats up faster, while the stretching oil in the center of the vacuum tank heats up the slowest. This results in poor uniformity of heating of the stretching oil inside the vacuum tank, leading to poor vacuum oil filtration performance. Utility Model Content

[0005] The purpose of this invention is to provide an integrated offline filtration and purification device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an offline integrated filtration and purification device, including a vacuum filtration mechanism and a purification filtration mechanism. The vacuum filtration mechanism includes a vacuum tank, a vacuum pump, a condenser assembly, an oil discharge pump, and a heating tube assembly. The purification filtration mechanism includes a coarse filter and several fine filters. The vacuum pump is connected to the top of the vacuum tank through the condenser assembly. The heating tube assembly is connected to the top of the vacuum tank. The heating tube assembly includes a first heating tube and several second heating tubes. The first heating tube is connected to one of the second heating tubes through the coarse filter.

[0007] Furthermore, an oil inlet pipe is connected to one end of the outer wall of the first heating tube, and a first valve is connected to the oil inlet pipe.

[0008] Furthermore, the vacuum tank is connected to the fine filter via an oil discharge pump, and the vacuum tank is also connected to the coarse filter via the oil discharge pump. Two adjacent fine filters are connected in series, and the fine filter furthest from the oil discharge pump is connected to an oil outlet pipe, which is connected to a second valve.

[0009] Furthermore, the oil discharge pump is connected to a main pipeline and two branch pipelines. The oil discharge pump is connected to the main pipeline and the two branch pipelines. The two branch pipelines are respectively connected to the fine filter and the coarse filter. The top of the outer wall of the main pipeline is provided with a threaded sealing plug.

[0010] Furthermore, the condenser assembly includes a first condenser, a condenser, and a second condenser, and the vacuum pump, the first condenser, the condenser, the second condenser, and the vacuum tank are connected in series via pipes.

[0011] Furthermore, the bottom of the outer wall of the first condenser tube is connected to the bottom of the outer wall of the condenser via a first connecting pipe, and the top of the outer wall of the second condenser tube is connected to the top of the outer wall of the condenser via a second connecting pipe. Both the bottom of the first condenser tube and the bottom of the second condenser tube are provided with drain outlets.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0013] 1. This utility model incorporates a vacuum filtration mechanism, a purification filtration mechanism, a vacuum tank, a vacuum pump, a condenser assembly, an oil discharge pump, and a heating element assembly. The vacuum pump evacuates the vacuum tank via the condenser assembly. Under atmospheric pressure, the oil enters the first heating element through the inlet pipe for preheating before entering the coarse filter. The first heating element effectively reduces the kinematic viscosity of the oil, allowing it to flow more smoothly during the initial filtration and purification process in the coarse filter, thus accelerating the purification rate. After passing through the coarse filter, the oil enters the second heating element for further heating. After being heated by multiple second heating elements, the oil reaches the temperature required for vacuum filtration and is then fed into the vacuum tank from the top for further vacuum filtration. During the heating process by multiple second heating elements, the contact between the oil and the heating elements is more uniform, resulting in more even heating and a more uniform temperature inside the vacuum tank, thereby improving the vacuum filtration effect.

[0014] 2. In this utility model, the oil undergoing vacuum filtration inside the vacuum tank is transported to the fine filter for further filtration. The oil after vacuum filtration can be re-transported to the coarse filter for reheating and vacuum filtration, preventing substandard oil from being discharged during the vacuum filtration process. Workers can sample the oil in the main pipeline by puncturing the sealing plug. If the oil meets the vacuum filtration standards, it is transported to the fine filter via a branch pipeline for further filtration before being discharged. If the oil does not meet the vacuum filtration standards, it is transported back to the coarse filter via a branch pipeline for repeated coarse filtration, heating, and vacuum filtration to ensure the purity of the output oil.

[0022] 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.

[0023] Please see Figures 1-5 This utility model provides a technical solution: an offline integrated filtration and purification device, including a vacuum filtration mechanism 1 and a purification filtration mechanism 2. The vacuum filtration mechanism 1 includes a vacuum tank 101, a vacuum pump 102, a condenser assembly 103, an oil discharge pump 104, and a heating tube assembly 105. The purification filtration mechanism 2 includes a coarse filter 201 and several fine filters 202. The vacuum pump 102 is connected to the top of the vacuum tank 101 through the condenser assembly 103. The heating tube assembly 105 is connected to the top of the vacuum tank 101. The heating tube assembly 105 includes a first heating tube 1051 and several second heating tubes 1052. The first heating tube 1051 is connected to one of the second heating tubes 1052 through the coarse filter 201. Both the coarse filter 201 and the fine filter 202 are filled with filter elements of corresponding specifications, and the filter elements can be replaced periodically according to usage. The first heating tube 1051 and the second heating tube 1052 are both tubular heaters and can be electric heating tubes.

[0024] In one embodiment, one end of the outer wall of the first heating tube 1051 is connected to an oil inlet pipe 1053, and a first valve 1054 is connected to the oil inlet pipe 1053. The oil to be processed enters the interior of the first heating tube 1051 through the oil inlet pipe 1053 after passing through the first valve 1054 for preheating treatment.

[0025] In one embodiment, the vacuum tank 101 is connected to the fine filter 202 via the oil discharge pump 104, allowing the oil undergoing vacuum filtration in the vacuum tank 101 to be transported to the fine filter 202 for further filtration. The vacuum tank 101 is also connected to the coarse filter 201 via the oil discharge pump 104, allowing the oil after vacuum filtration in the vacuum tank 101 to be re-heated and vacuum-filtered again, preventing substandard oil from being processed during the vacuum filtration process. Two adjacent fine filters 202 are connected in series, ensuring that the oil entering the fine filters 202 passes through all the fine filters in the equipment before being discharged, guaranteeing the oil purification effect. One fine filter 202 furthest from the oil discharge pump 104 is connected to an oil outlet pipe 203, which is equipped with a second valve 204, allowing the processed oil to be discharged from the oil outlet pipe 203.

[0026] In one embodiment, the oil discharge pump 104 is connected to a main pipeline 1021 and two branch pipelines 1022. The oil discharge pump 104 is connected to the main pipeline 1021 and the two branch pipelines 1022. The two branch pipelines 1022 are respectively connected to the fine filter 202 and the coarse filter 201. The top of the outer wall of the main pipeline 1021 is provided with a threaded sealing plug 1023. The operator can puncture the sealing plug 1023 to sample the oil inside the main pipeline 1021. When the oil meets the vacuum filtration standard, the oil is transported to the fine filter 202 through the branch pipelines 1022 for fine filtration and then discharged. When the oil does not meet the vacuum filtration standard, the oil is transported to the coarse filter 201 through the branch pipelines 1022 for coarse filtration, heating, and vacuum filtration to ensure the purity of the output oil.

[0027] In one embodiment, the condenser assembly 103 includes a first condenser 1031, a condenser 1032, and a second condenser 1033. The vacuum pump 102, the first condenser 1031, the condenser 1032, the second condenser 1033, and the vacuum tank 101 are connected in series via pipes, ensuring that the vacuum pump 102 can sequentially pass through the first condenser 1031, the condenser 1032, and the second condenser 1033 to perform vacuuming on the vacuum tank 101, while simultaneously ensuring that the vacuum tank 101 produces a vacuum inside. The generated water vapor quickly enters the condenser tube assembly 103, preventing water vapor from accumulating at the top of the vacuum tank 101; the first condenser tube 1031 and the second condenser tube 1033 are tubular condensers, and the condenser 1032 is a plate condenser; the coordinated use of the first condenser tube 1031, the condenser 1032, and the second condenser tube 1033 can effectively ensure that water vapor can quickly condense into liquid and remain inside the condenser tube assembly 103 along the condensation path of water vapor, preventing water vapor from entering the vacuum pump 102.

[0028] In one embodiment, the bottom of the outer wall of the first condenser tube 1031 is connected to the bottom of the outer wall of the condenser 1032 via a first connecting pipe 1035, ensuring that both liquid water and water vapor inside the condenser 1032 can enter the first condenser tube 1031; the top of the outer wall of the second condenser tube 1033 is connected to the top of the outer wall of the condenser 1032 via a second connecting pipe 1036, allowing water vapor entering the second connecting pipe 1036 to quickly enter the condenser 1032; both the bottom of the first condenser tube 1031 and the second condenser tube 1033 are provided with drain outlets 1034, which are used to drain the condensed liquid inside the first condenser tube 1031 and the second condenser tube 1033. At the same time, a water storage tank can be set at the bottom of the first condenser tube 1031, so that the liquid water generated inside the first condenser tube 1031 can directly enter the water storage tank for subsequent unified discharge treatment.

[0029] The working principle of this utility model:

[0030] Refer to the instruction manual appendix Figures 1-5 This utility model includes a vacuum filtration mechanism 1, a purification filtration mechanism 2, a vacuum tank 101, a vacuum pump 102, a condenser tube assembly 103, an oil discharge pump 104, and a heating tube assembly 105. The vacuum pump 102 evacuates the vacuum tank 101 through the condenser tube assembly 103. Under atmospheric pressure, the oil enters the first heating tube 1051 from the oil inlet pipe 1053 for preheating before entering the coarse filter 201. The first heating tube 1051 can effectively reduce the kinematic viscosity of the oil, making the oil flow more smoothly in the subsequent initial filtration and purification process in the coarse filter 201, and effectively accelerating the oil purification rate.

[0031] After passing through the coarse filter 201, the oil enters the second heating tube 1052 for heating treatment. After being heated by multiple second heating tubes 1052, the oil reaches the temperature required for vacuum filtration. Then, it is sent from the top of the vacuum tank 101 into the vacuum tank 101 for vacuum filtration treatment. During the heating process of the oil entering the vacuum tank 101 through multiple second heating tubes 1052, the contact between the oil and the heating components is more uniform, making the oil heating more uniform. This results in a more uniform temperature of the oil entering the vacuum tank 101, thereby improving the vacuum filtration effect of the oil.

[0032] The oil entering the vacuum tank 101 is separated into a semi-mist state by the rapid rotation of the spray blades. The water in the oil evaporates rapidly under the action of vacuum and high temperature. At the same time, the vacuum pump 102 extracts the water vapor evaporated inside the vacuum tank 101 through the condenser tube assembly 103 by drawing a vacuum. The water vapor enters the condenser tube assembly 103 and condenses into small droplets, which gradually collect into water and are retained in the condenser tube assembly 103. After the oil is processed, the drain port 1034 of the condenser tube assembly 103 can be opened to drain the water to avoid affecting subsequent work. The oil that has been vacuum filtered is transported by the oil discharge pump 104 to the purification and filtration mechanism 2 for fine filtration. Finally, after the oil has been filtered and purified, it is discharged from the purification and filtration mechanism 2.

[0033] 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.
