Description

Technical Field

[0001] The utility model relates to the technical field of antioxidant production, and more specifically to a filtering device used for antioxidant production. Background Art

[0002] In the technical field of antioxidant production, filtration devices play a vital role. As an important chemical additive, the purity and quality of antioxidants directly affect the performance and service life of the product. Therefore, efficient and reliable filtration devices are needed to remove impurities in antioxidants to ensure product quality.

[0003] At present, in the field of chemical production, the production process of antioxidants requires efficient filtration to remove impurities to ensure product quality. Traditional antioxidant filtration devices usually use a simple bag filtration structure, relying only on filter bags to intercept impurities.

[0004] There are many problems in this prior art solution. Due to the lack of an effective pretreatment structure, it is difficult to preliminarily treat the tiny impurities and odors in the antioxidant before entering the filter bag, which results in a large filtration load on the filter bag and makes it difficult to improve the purity of the antioxidant. Moreover, during long-term use of the filter bag, impurities are easily accumulated and clogged in its pores. Once clogged, not only will the filtration efficiency drop sharply, but the filter bag may also be damaged due to increased pressure, thereby affecting the continuity and stability of the entire production. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a filtering device for producing an antioxidant to solve the problems existing in the above-mentioned background technology.

[0006] The utility model provides the following technical solution: a filtering device for antioxidant production, comprising a filter housing, a supporting structure, an inlet pipe, an outlet pipe, and a filter bag. The antioxidant enters the filter bag inside the filter housing through the inlet pipe for filtration. An adsorption cylinder for pre-treating the antioxidant is arranged on the inner wall surface of the filter bag. The adsorption cylinder is cylindrical and the surface of the adsorption cylinder is honeycomb-shaped. The adsorption cylinder is fixed to the inner wall by a detachable connection.

[0007] Furthermore, the adsorption cylinder also includes a connecting ring at the top, and a clamp 1 is distributed in a ring shape on the connecting ring, and is clamped on the top of the filter bag by the clamp 1.

[0008] Furthermore, the adsorption cylinder is made of activated carbon material.

[0009] Furthermore, a turbine assembly located at the bottom of the filter bag is installed on the inner bottom surface of the filter housing, and the turbine assembly includes an underwater motor located on the inner bottom surface of the filter housing and turbine blades fixedly connected to the output shaft of the underwater motor.

[0010] Furthermore, a cover plate is provided on the top of the filter housing, and the size of the filter housing is vertically matched with the size of the cover plate.

[0011] Furthermore, a fixing ring is sleeved on the outer cylinder of the filter housing, and a vibration motor is installed on the fixing ring.

[0012] Furthermore, a pressure sensor is provided on the top of the outer side of the filter housing, and the pressure sensor is installed on the top of the cover plate.

[0013] Technical effects and advantages of the utility model:

[0014] 1. In the utility model, an adsorption cylinder is arranged on the inner wall of the filter bag, which is cylindrical and has a honeycomb surface and is made of activated carbon. The good adsorption performance of activated carbon and the increased adsorption area of ​​the honeycomb structure can effectively adsorb tiny impurities and odors in the antioxidant, greatly improving the purity of the antioxidant. At the same time, the adsorption cylinder and the filter bag adopt a detachable connection method of a top connecting ring and a clamp, which is convenient for rapid replacement when the adsorption cylinder is saturated or needs maintenance, reducing the equipment maintenance cost, and is conducive to the long-term stable operation of the entire filtering device, ensuring the continuity and stability of the antioxidant production process.

[0015] 2. In the utility model, the turbine assembly installed on the bottom surface of the filter housing plays an important role. The underwater motor drives the turbine blades to rotate, so that the antioxidant forms a strongly stirred flow field under the filter bag, effectively promoting the uniform distribution of the antioxidant, avoiding local uneven concentrations caused by differences in the physical properties of the components, and allowing the filtration process to be carried out evenly across the entire cross-section of the filter bag, thereby improving the consistency and stability of the filtration effect. In addition, the rotation of the turbine blades generates an upward disturbance force, preventing impurities from depositing at the bottom of the filter bag to form a sedimentation layer, so that the impurities remain suspended or semi-suspended, making it easier to be intercepted by the filter bag or adsorbed by the adsorption cylinder, reducing the risk of filter bag blockage caused by impurity deposition, extending the service life of the filter bag, and reducing the frequency and cost of equipment operation and maintenance, ensuring efficient and stable operation of the filtration device.

[0016] 3. In the utility model, the pressure sensor arranged on the top of the outer side of the filter housing can monitor the pressure in the filter bag in real time. A common industrial pressure sensor is selected, and when the pressure exceeds the set value, an alarm signal can be issued in time to remind the operator to handle it. This effectively avoids the problem of reduced filtering effect and production interruption caused by clogging or damage of the filter bag, and ensures the safety and stability of production. At the same time, the pressure sensor helps the operator to grasp the operating status of the filter device in time, so as to plan maintenance measures in advance, further extend the service life of the equipment, and improve the reliability and controllability of the entire production process.

DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0024] Figure 1 - Figure 5 It is the best embodiment of the utility model, and the following Figure 1 - Figure 5 The utility model is further described.

[0025] Embodiment 1, refer to the attached Figure 1 - Figure 3 .

[0026] A filtering device for producing an antioxidant, in this embodiment, a filtering device for producing an antioxidant, comprises a filter housing 1, a support structure 101, an inlet pipe 2, an outlet pipe 201, and a filter bag 3. The filter housing 1 is usually made of a strong and durable material, such as stainless steel. The inlet pipe 2 and the outlet pipe 201 are passages for the antioxidant to enter and exit the filtering device. The inlet pipe 2 introduces the antioxidant to be filtered into the filtering device, and after filtering, the pure antioxidant flows out through the outlet pipe 201. The size and material of the inlet pipe 2 and the outlet pipe 201 need to be selected according to the flow rate, viscosity and other characteristics of the antioxidant to ensure that the antioxidant can flow smoothly and will not corrode or block the pipe. A cover plate 102 is provided on the top of the filter housing 1, and the size of the filter housing 1 is adapted to the size of the cover plate 102. After the filter housing 1 and the cover plate 102 are docked, they are movably connected through the corresponding locking components at the upper and lower edges of the filter housing 1 and the cover plate 102. The locking components in this technical solution are existing well-known technologies and will not be described in detail in this solution.

[0027] Specifically, an adsorption cylinder 4 for pre-treating the antioxidant is arranged on the inner wall surface of the filter bag 3. The adsorption cylinder 4 is cylindrical and has a honeycomb surface. It is made of activated carbon material and is clamped on the top of the filter bag 3 by a connecting ring 41 at the top and a clamp 42 distributed in a ring shape on the connecting ring 41. The clamp 42 can use a clip to achieve a detachable connection with the inner wall of the filter bag 3. This structural combination can effectively adsorb tiny impurities and odors in the antioxidant and improve the purity of the antioxidant. The advantages are that the honeycomb structure increases the adsorption area and improves the adsorption efficiency; the activated carbon material has good adsorption performance and will not react chemically with the antioxidant; the detachable connection method facilitates the replacement and maintenance of the adsorption cylinder 4 and reduces costs. In addition, this structure also has the beneficial effect of facilitating cleaning and maintaining the long-term stable operation of the filter device.

[0028] Embodiment 2, based on embodiment 1, refers to the attached Figure 4 .

[0029] In this embodiment, in this antioxidant filtering device, we have made further optimization and improvement based on Example 1.

[0030] In order to improve better, a turbine assembly located at the bottom of the filter bag 3 is installed on the inner bottom surface of the filter housing 1. The turbine assembly includes an underwater motor 5 located on the inner bottom surface of the filter housing 1, and multiple groups of turbine blades 501 fixedly connected on the output shaft of the underwater motor 5. The turbine blades 501 in this technical solution approach the bottom of the filter bag 3 and do not contact the bottom of the filter bag 3, so they will not touch the filter bag 3 during the stirring process. In this technical solution, underwater motors such as the QYDB series are selected. This series of motors has the characteristics of good sealing, corrosion resistance, and strong power. It can adapt to the liquid environment inside the filter housing 1 and can stably output sufficient power to drive the turbine blades 501 to operate, meet the requirements of the filter device for stirring and mixing the antioxidant, and ensure the smooth progress of the filtration process. Different application scenarios and filter device scales may require the selection of QYDB series underwater motors or other suitable models of underwater motors of different powers and specifications according to actual conditions.

[0031] Such design improvements can promote uniform distribution of antioxidants; when the turbine blades 501 rotate under the filter bag 3, the antioxidant entering the filter housing 1 can form a strong stirring flow field in the bottom area. During the production process of antioxidants, there may be slight differences in the density, viscosity and other physical properties of its components. If it only relies on natural flow, local uneven concentrations are likely to occur. The stirring action of the turbine assembly can effectively break this unevenness, allowing the antioxidant to be fully mixed in the space below the filter bag 3, ensuring that the overall properties of the antioxidant are more uniform when entering the filter bag 3, so that the filtration process can be carried out evenly across the entire cross-section of the filter bag 3, avoiding differences in filtration effects due to excessively high or low local antioxidant concentrations.

[0032] At the same time, the design of the turbine assembly on the bottom surface of the filter housing 1 can also prevent the deposition of impurities. Impurities in the antioxidant tend to be deposited at the bottom of the filter housing 1 under the action of gravity. The continuous rotation of the turbine blades 501 generates an upward disturbance force, preventing impurities from accumulating in large quantities under the filter bag 3 to form a sedimentation layer. Once a sedimentation layer is formed, it will not only reduce the effective filtering space at the bottom of the filter housing 1, but may also make subsequent cleaning difficult due to the compaction of the sedimentation layer, and even damage the filter bag 3. The presence of the turbine assembly can keep the impurities in a suspended or semi-suspended state at all times, making it easier to be intercepted by the filter bag 3 or adsorbed by the adsorption cylinder 4.

[0033] Embodiment 3, based on embodiment 2, refers to the attached Figure 5 .

[0034] In this embodiment, a pressure sensor 6 is arranged on the top of the outer side of the filter housing 1, and a fixing ring 7 is sleeved on the outer cylinder of the filter housing 1, and a vibration motor 701 is installed on the fixing ring 7. The detection probe of the pressure sensor 6 passes through the bottom of the cover plate 102 and extends downward to the interior of the filter housing 1.

[0035] Regarding the vibration motor 701 in the present technical solution, during the antioxidant filtration process, some tiny impurities may gradually adhere to the pores of the filter bag 3, causing the pores to become clogged over time, affecting the filtration efficiency. The vibration generated by the vibration motor 701 when it is working is transmitted to the filter housing 1 through the fixing ring 7, thereby causing the filter bag 3 to also vibrate slightly. This vibration can destroy the adhesion stability of impurities on the pores of the filter bag 3, allowing the impurities that originally blocked the pores to detach under the action of vibration and return to the antioxidant liquid, and then can be adsorbed by the adsorption cylinder 4 or intercepted at other positions on the surface of the filter bag 3 when the antioxidant flows through the filter bag 3 again, thereby keeping the pores of the filter bag 3 unobstructed and ensuring that the filtration process can be carried out continuously and efficiently.

[0036] The vibration of the vibration motor 701 can cause the antioxidant liquid in the filter housing 1 to fluctuate. Since the adsorption cylinder 4 is located inside the filter bag 3, the fluctuation of the antioxidant liquid can cause relative movement between the antioxidant and the adsorption cylinder 4. This relative movement increases the collision chance and contact area between the antioxidant and the activated carbon on the surface of the adsorption cylinder 4. As mentioned above, the honeycomb structure of the adsorption cylinder 4 provides a large surface area for adsorption, but effective adsorption can only be achieved when the antioxidant fully contacts these surfaces. The liquid fluctuation and relative movement caused by the vibration motor 701 help the antioxidant molecules to penetrate deeper into the honeycomb pores of the adsorption cylinder 4 and combine with the active sites of the activated carbon, thereby enhancing the adsorption effect and further improving the purity of the antioxidant. Just like in a chemical reactor, stirring or vibration can sometimes speed up the contact and reaction rate between the reactants. Here, the vibration motor 701 strengthens the adsorption reaction by promoting the contact between the antioxidant and the adsorption cylinder 4.

[0037] Specifically, the pressure sensor 6 can monitor the pressure in the filter bag 3 in real time. In the filter device for antioxidant production, the pressure sensor 6 can select some common industrial pressure sensor models, such as SMP13 pressure sensor, etc. When the pressure exceeds the set value, an alarm signal is issued to remind the operator to deal with it in time. This structural coordination can ensure that the filter device operates within a safe pressure range. The advantage is that it avoids the decline in filtering effect and production interruption caused by clogging or damage of the filter bag 3, and improves the safety and stability of production. In addition, the setting of the pressure sensor 6 can also help the operator to understand the operating status of the filter device in time, so as to take corresponding maintenance measures and extend the service life of the equipment.

[0038] In this embodiment,

[0039] The working principle and use process of the utility model are as follows: when in use, first, the valve on the inlet pipe 2 is opened, and the antioxidant to be filtered flows into the filter housing 1 under the action of the pressure difference. When the antioxidant enters the filter housing 1, the underwater motor 5 at the bottom of the filter housing 1 is started, driving the turbine blades 501 to rotate. The rotation of the turbine blades 501 enables the antioxidant to form a good stirring flow field under the filter bag 3, so that the antioxidant components can be evenly mixed to prevent impurities from being deposited at the bottom of the filter bag 3.

[0040] The antioxidant then enters the filter bag 3, and the adsorption cylinder 4 arranged on the inner wall of the filter bag 3 begins to work. The adsorption cylinder 4 is made of activated carbon and is cylindrical with a honeycomb surface. It is fixed to the inner wall of the filter bag 3 through a connecting ring 41 and a clamp 42. When the antioxidant passes through the adsorption cylinder 4, the honeycomb structure greatly increases the contact area with the antioxidant. The activated carbon effectively adsorbs the tiny impurities and odors in the antioxidant with its good adsorption performance, thereby improving the purity of the antioxidant.

[0041] During the entire filtering process, the pressure sensor 6 located at the top of the outer side of the filter housing 1 monitors the pressure inside the filter bag 3 in real time. When the internal pressure of the filter bag 3 rises to a preset value due to the gradual increase of intercepted impurities, the pressure sensor 6 quickly sends out an alarm signal. At the same time, the vibration motor 701 installed on the fixing ring 7 can be started according to actual needs. The vibration generated by the vibration motor 701 when working is transmitted to the filter housing 1 through the fixing ring 7 and causes the filter bag 3 to vibrate slightly, which helps to destroy the attachment of impurities to the pores of the filter bag 3, so that the impurities blocking the pores are separated and returned to the antioxidant, which can be adsorbed by the adsorption cylinder 4 again or re-intercepted by the filter bag 3, so as to keep the pores of the filter bag 3 unobstructed; and the vibration also causes the antioxidant liquid in the filter housing 1 to fluctuate, enhancing the relative movement between the antioxidant and the adsorption cylinder 4, and further improving the adsorption effect.

[0042] When the adsorption cartridge 4 needs to be replaced or maintained, the operator can easily open the cover plate 102 on the top of the filter housing 1, unlock the locking assembly, and then remove the connecting ring 41 by loosening the clamp 42, thereby removing the adsorption cartridge 4 from the filter bag 3 for corresponding processing.

[0043] After filtration and adsorption, the purified antioxidant flows out of the filter housing 1 through the outlet pipe 201 and enters the subsequent production process or storage link. During the whole process, the support structure 101 provides stable support for the filter housing 1 to ensure the smooth operation of the device.
