Description

Technical Field

[0001] This utility model relates to the field of chemical product manufacturing technology, and in particular to a raw material filtration device for chemical product manufacturing. Background Technology

[0002] In the production of chemical products (such as coatings, adhesives, composite materials, and polymer additives), the purity of raw materials directly determines the performance stability and quality pass rate of the final product. Raw materials often contain impurities (such as mechanical impurities, incompletely dissolved solid particles, and externally introduced dust). If these impurities are introduced directly into the reaction or molding process without filtration, it can lead to problems such as product stratification, sedimentation, decreased mechanical properties (such as reduced strength and increased brittleness), and appearance defects (such as spots and scratches). It can even cause blockages in production equipment (such as reaction vessels, pipelines, and nozzles), resulting in downtime for maintenance and increased production costs.

[0003] As the chemical industry develops towards high performance and multifunctionality, the production of more and more chemical products requires resins (such as epoxy resins, phenolic resins, polyurethane resins, and acrylic resins) as core raw materials or modified components. The physicochemical properties of resin raw materials differ significantly from those of conventional chemical raw materials, leading to intractable technical bottlenecks in the practical application of existing filtration devices. Resin substances (especially solid resin melts and high-viscosity liquid resins) have high viscosity and low fluidity at room temperature or low temperature. When such resin raw materials enter existing filtration devices, the low fluidity will cause the raw materials to accumulate on the surface of the filter media, making it difficult to quickly penetrate the filter pores, resulting in a significant decrease in the filtration rate, which is not conducive to matching the continuous rhythm of chemical production. High-viscosity resins easily adhere to the pores of filter media, causing "filter pore blockage." This necessitates frequent shutdowns to disassemble and clean or replace the filter media, increasing labor costs and causing production interruptions. Furthermore, increasing the feed pressure to facilitate raw material filtration can damage the filter media, allowing impurities to enter subsequent processes and posing a product quality risk. Therefore, this invention proposes a novel solution. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a raw material filtration device for chemical product production. This device can solve the problem that low fluidity causes raw materials to accumulate on the surface of the filter material, making it difficult for them to quickly penetrate the filter pores, resulting in a significant decrease in the filtration rate and making it difficult to match the continuous rhythm of chemical production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material filtration device for chemical product production, comprising a base on which a resin filter tank is installed; A filter assembly is disposed inside a resin filter tank.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] Please see Figure 1-8 This utility model provides a technical solution: a raw material filtration device for chemical product production. The upper end of the base 1 is fixedly connected to the resin heating tank 2, providing stable support for the entire device. The resin heating tank 2 is wrapped with a jacketed heating sleeve 4. The jacketed heating sleeve 4 has a hollow structure, and two oil pipes 5 fixed on its surface can be used to pass high-temperature oil. Through heat conduction, the resin in the resin heating tank 2 is heated, breaking the high viscosity characteristics of the resin and solving the filtration problem caused by the low fluidity of the resin.

[0027] A stirrer 6 is installed on the resin heating tank 2. The blades of the stirrer 6 extend into the tank. After starting, it can stir the heated resin, which on the one hand makes the resin heat evenly and avoids local viscosity differences; on the other hand, it breaks up the agglomerated particles in the resin, reduces the impurity interception pressure of the subsequent filter components, and improves the filtration accuracy.

[0028] The resin heating tank 2 is connected to the single screw pump 7 via the first connecting pipe 8. The discharge end of the single screw pump 7 is connected to the resin filter tank 3 via the second connecting pipe 9. The third connecting pipe 11, which is fixed to the inner wall of the resin filter tank 3, passes through the first filter cylinder limiting frame 12, and accurately introduces the resin into the resin filter cylinder 17. The single screw pump 7 has low shear and stable flow characteristics, which can avoid sudden pressure changes when conveying high viscosity resin and prevent raw material loss or particle breakage.

[0029] The resin filter tank 3 has a first filter cylinder limiting frame 12 and a second filter cylinder limiting frame 13 fixed inside. The opposite surfaces of the two are rotatably connected to the resin filter cylinder 17. The first drive motor 16 fixed on the left side of the first filter cylinder limiting frame 12 drives the resin filter cylinder 17 to rotate through the connecting shaft 18. The surface of the resin filter cylinder 17 has filter holes evenly opened. The first guide plate 20 and the spiral second guide plate 21 are fixed inside. When rotating, the resin permeates through the filter holes under the action of gravity and centrifugal force, and impurities are intercepted in the cylinder.

[0030] A baffle plate 23 is fixed to the upper end of the first filter cartridge limiting frame 12 and the second filter cartridge limiting frame 13. Multiple scrapers 22 are fixed to the surface of the resin filter cartridge 17. The baffle plate 23 can block the resin thrown out during rotation, avoiding waste and pollution. The scraper 22 rotates synchronously with the resin filter cartridge 17, scraping off the resin adhering to the inside of the baffle plate 23, preventing the resin from drying and accumulating, and reducing the burden of subsequent cleaning.

[0031] The second filter cartridge limit frame 13 is connected to the sealing flange 14 by bolts on the right side to ensure that the resin does not leak during filtration. After filtration, the sealing flange 14 is removed and the internal impurities can be cleaned through the opening at the right end of the resin filter cartridge 17. The lower end of the resin filter tank 3 is funnel-shaped, and the resin discharge pipe 15 fixed at the bottom can transport the filtered pure resin to the subsequent process to complete the entire filtration process.

[0032] Working principle: After the resin raw material (such as solid molten resin or high-viscosity liquid resin) is put into the resin heating tank 2 through the feed pipe at the top, high-temperature oil is introduced into the two oil pipes 5 on the surface of the jacket heating jacket 4 (the oil temperature is adjusted according to the type of resin to ensure that the resin viscosity is reduced to a flowable state). The jacket heating jacket 4 is a hollow structure that can evenly wrap the outside of the resin heating tank 2 and transfer heat to the resin in the tank through heat conduction, breaking the high viscosity characteristics of the resin, improving its fluidity, and reducing the risk of filter media accumulation and clogging in the subsequent filtration process.

[0033] Meanwhile, heating tape is wrapped around the surfaces of the first connecting pipe 8, the second connecting pipe 9 and the third connecting pipe 11 to maintain the temperature of the resin during the transportation process through auxiliary heating, so as to avoid the resin temperature from dropping rapidly and the viscosity from rising due to heat dissipation from the pipes, and to ensure that the raw material always flows stably in a low viscosity state.

[0034] Start the stirrer 6 installed on the resin heating tank 2. The stirrer blades continuously stir the heated resin in the tank. On the one hand, the resin is heated more evenly, avoiding uneven viscosity caused by local temperature differences. On the other hand, it can break up any small agglomerates that may exist in the resin, reducing the pressure of impurity interception in the subsequent filtration stage and improving the filtration accuracy.

[0035] When the resin in the resin heating tank 2 reaches the preset temperature and viscosity, the single screw pump 7 is started. The single screw pump 7 draws resin raw material from the resin heating tank 2 through the first connecting pipe 8 at the feed end, and then steadily delivers the resin to the inside of the resin filter tank 3 through the second connecting pipe 9 at the discharge end, and accurately introduces it into the internal cavity of the resin filter cylinder 17 through the third connecting pipe 11.

[0036] The single screw pump 7 features low shear and stable flow, which can avoid raw material loss or particle breakage caused by sudden pressure changes during the transportation of high-viscosity resin. At the same time, it can continuously provide stable feed pressure to ensure that the resin enters the filter assembly evenly and matches the rhythm of subsequent rotary filtration.

[0037] Start the first drive motor 16 fixed on the left side of the first filter cartridge limit frame 12. The output end of the first drive motor 16 drives the connecting shaft 18 to rotate. The connecting shaft 18 drives the resin filter cartridge 17 to rotate synchronously through the filter cartridge support frame 19 fixed on the surface (fixed to the inner wall of the resin filter cartridge 17).

[0038] Since the first filter cartridge limiting frame 12, the second filter cartridge limiting frame 13 and the resin filter cartridge 17 are all inclined, and the surface of the resin filter cartridge 17 is uniformly provided with filter holes, during the rotation, the resin flows downward along the spiral second guide plate 21 on the inner wall of the resin filter cartridge 17 under the dual action of gravity and centrifugal force. During the flow, the resin permeates to the outside of the resin filter cartridge 17 through the filter holes, while mechanical impurities and undissolved solid particles in the resin are intercepted inside the resin filter cartridge 17 by the filter holes.

[0039] Meanwhile, the multiple first guide plates 20 fixed inside the resin filter cartridge 17 can guide the resin to be evenly distributed in the cavity inside the cartridge, avoiding local resin accumulation that could cause filter hole blockage and further improving filtration efficiency.

[0040] The baffle plate 23 fixed to the upper end of the first filter cartridge limiter 12 and the second filter cartridge limiter 13 can block the resin thrown out by centrifugal force when the resin filter cartridge 17 rotates, preventing the resin from splashing onto the inner wall of the resin filter tank 3 and causing waste or pollution. At the same time, the inclined structure of the baffle plate 23 is adapted to the inclined direction of the resin filter cartridge 17, so that the blocked resin flows down along the inner side of the baffle plate 23 and flows back into the filtered resin flow on the outer side of the resin filter cartridge 17, ensuring that there is no loss of raw materials.

[0041] Multiple scrapers 22 fixed on the surface of the resin filter cylinder 17 rotate synchronously with the resin filter cylinder 17, which can scrape off the resin adhering to the inside of the baffle plate 23 in real time, preventing the resin from accumulating and drying on the surface of the baffle plate 23, thus ensuring the anti-overflow effect of the baffle plate 23 and reducing the subsequent cleaning burden.

[0042] The pure resin filtered by the resin filter cartridge 17 flows downward along the inner wall of the resin filter tank 3. Since the lower end of the resin filter tank 3 is funnel-shaped, the resin can be collected at the bottom of the resin discharge pipe 15 and transported to the subsequent production process (such as the reactor or molding equipment) through the resin discharge pipe 15 to complete the entire process of raw material filtration.

[0043] When a single filtration task is completed or impurities accumulate to a certain level inside the resin filter cartridge 17, turn off all drive and heating equipment, and remove the sealing flange 14 fixed by bolts on the right side of the second filter cartridge limit frame 13. The sealing flange 14 can prevent resin from flowing out from the gap between the second filter cartridge limit frame 13 and the resin filter cartridge 17 during the filtration process, exposing the right end opening of the resin filter cartridge 17.

[0044] Impurities trapped inside the resin filter cartridge 17 can be directly cleaned through the opening on the right end. After cleaning, the sealing flange 14 can be reinstalled, and the device can be started for the next round of filtration. This enables convenient maintenance of the filter components, reduces downtime, and improves the continuous operation efficiency of the equipment.

[0045] Furthermore, the first drive motor 16 drives the resin filter cylinder 17 to rotate. Combined with the inclined setting of the resin filter cylinder 17 and the spiral second guide plate 21 on the inner wall, the resin flows at a uniform speed along the spiral path under the dual action of gravity and centrifugal force, avoiding the accumulation of raw materials on the surface of the filter material. The internal first guide plate 20 further guides the resin to be evenly distributed, reducing local stagnation. Compared with the existing fixed filter material filtration method, the filtration rate is improved, which can match the continuous rhythm of chemical production and avoid production interruptions caused by low filtration efficiency.

[0046] The resin temperature can be precisely controlled by the jacketed heating sleeve 4 (hollow structure with oil pipe 5 for high-temperature oil) on the outside of the resin heating tank 2, breaking the low flow characteristics of high viscosity resins (such as epoxy resin and phenolic resin); at the same time, heating tape is wrapped around the surface of the first connecting pipe 8, the second connecting pipe 9 and the third connecting pipe 11 to prevent the viscosity from rising due to cooling during resin transportation, ensuring that the resin always flows stably in a low viscosity state, laying the foundation for rapid filtration.

[0047] The uniformly distributed filter holes on the surface of the resin filter cartridge 17, combined with the rotary filtration mode, can reduce the adhesion of high-viscosity resin in the filter holes; at the same time, the axial pushing force generated when the spiral filter cartridge support frame 19 rotates can push the resin through the filter holes quickly, avoiding local resin accumulation and blockage.

[0048] Example 1: Application of spiral filter cartridge support frame 19 in high viscosity resin filtration (see Figure 8 ) The original cross-shaped filter cartridge support frame 19 is replaced with a spiral-shaped filter cartridge support frame 19. The spiral blades of the spiral support frame are tightly fixed to the inner wall of the resin filter cartridge 17, and the spiral direction is consistent with the spiral direction of the second guide plate 21 on the inner wall of the resin filter cartridge 17.

[0049] The axial pushing force of the spiral support frame can effectively overcome the flow resistance of high-viscosity resin, prevent resin from stagnating in the resin filter cartridge 17, improve the filtration rate, and meet the needs of continuous production.

[0050] The dispersing effect of the spiral blades ensures that the resin contacts the filter pores evenly, avoiding excessive local resin accumulation that could cause filter pore blockage, thus reducing the need for downtime for cleaning.

[0051] Example 2: Application of the spiral guide plate 10 inside the jacketed heating jacket 4 in the filtration of heat-sensitive resin (see...) Figure 7 ) A spiral guide plate 10 is fixedly connected to the inner side of the jacketed heating jacket 4. The spiral guide plate 10 extends the flow path and residence time of the high-temperature oil in the jacketed heating jacket 4, so that the heat of the oil is evenly transferred to the resin heating tank 2, reducing the temperature fluctuation range of the resin in the tank and avoiding resin degradation caused by excessive local temperature.

[0052] The oil heat transfer is more efficient, so that the temperature of the oil input through the oil pipe 5 can be reduced while still maintaining the temperature required by the resin, thus reducing energy consumption, improving energy utilization, and reducing production costs.

[0053] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
