Description

Technical Field

[0001] The utility model relates to the technical field of filter devices, in particular to a filter box for a reflux pump. Background Art

[0002] During the production process of carbon fiber composite materials, the carbon fiber first enters the resin tank for resin infiltration, so that the resin is fully infiltrated and dispersed on the surface and inside of the carbon fiber precursor, and then enters the molding mold. At this time, the carbon fiber precursor infiltrated with resin is squeezed by the mold joint, so that a certain amount of resin is retained in the carbon fiber precursor. The excess resin is squeezed and returned to the resin tank through the reflux pump.

[0003] In the prior art, the extruded refluxed resin is doped with extruded and broken carbon fiber raw yarn, iron wire, dry glue and other substances. The resin carrying impurities is refluxed to the resin tank through a reflux pump and then recycled. Therefore, the impurities easily clog the reflux pump. The clogged reflux pump is not easy to clean and can only be replaced, which reduces the use time of the equipment and increases the production cost. In addition, the gum with foreign matter will enter the manufactured carbon fiber composite material plate, reducing the quality of the plate. Utility Model Content

[0030] During the production process of carbon fiber composite materials, the carbon fiber first enters the resin tank for resin infiltration, so that the resin is fully infiltrated and dispersed on the surface and inside of the carbon fiber precursor, and then enters the molding mold. At this time, the carbon fiber precursor infiltrated with resin is squeezed by the mold joint, so that a certain amount of resin is retained in the carbon fiber precursor. The excess resin is squeezed and returned to the resin tank through the reflux pump.

[0031] In the prior art, the extruded refluxed resin is doped with extruded and broken carbon fiber raw yarn, iron wire, dry glue and other substances. The resin carrying impurities is refluxed to the resin tank through a reflux pump and then recycled. Therefore, the impurities easily clog the reflux pump. The clogged reflux pump is not easy to clean and can only be replaced, which reduces the use time of the equipment and increases the production cost. In addition, the gum with foreign matter will enter the manufactured carbon fiber composite material plate, reducing the quality of the plate.

[0032] Combine the following Figure 1-Figure 4 The embodiments of the present utility model are further described.

[0033] In order to solve the above technical problems, the utility model provides a filter box for a reflux pump. By connecting the filter box with the reflux pump and arranging a filter box in the funnel, the filter box can filter carbon fiber yarn, iron wire, dry glue and other substances in the resin, effectively reducing the risk of damage to the reflux pump, reducing production costs, and improving the quality of the plate. At the same time, by arranging a clamping part on the filter box, the filter box can be easily extended into the funnel, and the clamping part can be firmly clamped on the upper end of the wall of the funnel, simplifying the installation process, improving the installation efficiency, and also ensuring the stability and reliability of the filter box in the funnel. At least one fixing part is provided on the outer surface of the funnel, so that the filter box can be conveniently fixed on the reflux pump or other related equipment, enhancing the stability of the filter box, preventing displacement or falling off due to vibration or resin impact, and improving the stability and safety of the entire system.

[0034] An exemplary embodiment of the present disclosure provides a filter box for a reflux pump, such as Figure 1 As shown, the filter box includes a funnel 1 and a filter box 2 disposed in the funnel 1; wherein the funnel 1 and the filter box 2 can be made of the same material or different materials, which is not limited here. wherein the filter box 2 can be made of a stainless steel plate, and then a plurality of through holes are arranged on the stainless steel plate according to actual conditions, or it can be woven from a plurality of stainless steel wires, and during the weaving process, holes of a set diameter are reserved between adjacent stainless steel wires.

[0035] A first opening 21 is provided at the upper end of the filter box 2, and a clamping portion 3 is provided on the periphery of the first opening 21. The filter box 2 extends into the interior of the funnel 1, and the clamping portion 3 is clamped on the upper end of the bucket wall of the funnel 1; at least one fixing portion 4 is provided on the outer surface of the funnel 1, and the fixing portion 4 is used for fixing and installing the filter box. By providing the clamping portion 3 on the filter box 2, the filter box 2 can be conveniently extended into the interior of the funnel 1, and the clamping portion 3 can be firmly clamped on the upper end of the bucket wall of the funnel 1, which simplifies the installation process, improves the installation efficiency, and also ensures the stability and reliability of the filter box 2 in the funnel 1. At least one fixing portion 4 is provided on the outer surface of the funnel 1, so that the filter box can be conveniently fixed on the reflux pump or other related equipment, enhances the stability of the filter box, prevents displacement or falling off due to vibration or resin impact, and improves the stability and safety of the entire system.

[0036] In some embodiments of the present invention, referring to Figure 1 and Figure 2A support frame is provided on the outside of the funnel 1, and a fixing groove 5 is provided on the fixing portion 4, and the fixing groove 5 is sleeved and fixed on the support frame. The support frame can be an additionally installed bracket, or a support frame for installing a reflux pump. It can be understood that a filter box is placed on the upper end of the support frame, and a reflux pump is installed and fixed on the support frame below the filter box. The funnel 1 is fixedly installed on the support frame by the fixing portion 4, and the support frame can provide additional support for the funnel 1, effectively preventing shaking or tilting caused by resin flow or external force. The fixing portion 4 is sleeved and fixed on the support frame by the fixing groove 5, ensuring a firm connection between the funnel 1 and the support frame, further enhancing the stability of the entire structure.

[0037] In some embodiments of the present invention, referring to Figure 1 and Figure 4 The fixing part 4 includes a first fixing member 41 and a second fixing member 42. A first groove is provided on the first surface of the first fixing member 41, and a second groove is provided on the second surface of the second fixing member 42. A first fixing hole is also provided on the first fixing member 41, and a second fixing hole is also provided on the second fixing member 42. The first fixing member 41 is provided on the outer surface of the funnel 1, and the second fixing member 42 is rotatably connected to the first fixing member 41; the second fixing member 42 can rotate between a first position and a second position relative to the first fixing member 41. Exemplarily, the first fixing member 41 is fixed to the outer surface of the funnel 1, and the first fixing member 41 and the second fixing member 42 are connected by a hinge, so that the second fixing member 42 can rotate between the first position and the second position relative to the first fixing member 41.

[0038] In the first position, the first surface and the second surface are opposite to each other, so that the first groove and the second groove are spliced ​​to form a fixing groove 5, and the first fixing hole and the second fixing hole are coaxial, so that the first fixing hole and the second fixing hole can be fixedly connected by a fastener 6. In the second position, the first surface and the second surface are away from each other. When in use, the second fixing member 42 is rotated to clamp the first groove to one side of the fixing frame, and then the second fixing member 42 is rotated so that the second surface is close to the first surface. After the second groove is clamped to the other side of the fixing frame, the fastener 6 is used to pass through the second fixing hole and the first fixing hole in sequence to connect and fix the first fixing member 41 and the second fixing member 42. Among them, the fastener 6 can be a bolt, the first fixing hole is a threaded hole, and a thread matching the bolt is provided in the first fixing hole. The connection tightness of the first fixing member 41 and the second fixing member 42 is adjusted by adjusting the length of the bolt screwed into the first fixing hole.

[0039] In this way, the second fixing member 42 can rotate between the first position and the second position relative to the first fixing member 41, making the installation and removal of the funnel 1 more flexible and convenient. In the first position, the first groove and the second groove are spliced ​​to form a fixing groove 5, so that the funnel 1 can be firmly fixed on the support frame; and in the second position, the first surface and the second surface are away from each other, so that the funnel 1 can be easily removed for cleaning, replacement or movement.

[0040] In some embodiments of the present invention, referring to Figure 1 and Figure 3 The filter box 2 and the clamping part 3 are an integrally formed structure. The integrally formed structure can make the connection between the filter box 2 and the clamping part 3 more secure, and is not prone to loosening or falling off, ensuring that the filter box 2 can maintain a good filtering effect during use and reducing the potential risks caused by loose components. At the same time, it is formed simultaneously during the manufacturing process without the need for additional assembly steps, which not only improves production efficiency but also reduces production costs.

[0041] In some embodiments of the present invention, referring to Figure 1 and Figure 3 The clamping part 3 includes a first fixing plate 31 and a second fixing plate 32 which are arranged at an angle. The first side of the first fixing plate 31 is connected to the periphery of the first opening 21 of the filter box 2. The second side of the first fixing plate 31 which is opposite to the first side is connected to the second fixing plate 32. The first fixing plate 31 abuts against the top surface of the upper end of the bucket wall of the funnel 1, and the second fixing plate 32 abuts against the outer side surface of the upper end of the bucket wall of the funnel 1. In this way, the first fixing plate 31 abuts against the top surface of the upper end of the bucket wall of the funnel 1, providing vertical support for the filter box 2, ensuring that it can maintain a stable position during use. The second fixing plate 32 abuts against the outer side surface of the upper end of the bucket wall of the funnel 1, further enhancing the horizontal stability of the filter box 2 and preventing it from shaking or tilting. The second side of the first fixing plate 31 is connected to the second fixing plate 32 to form a stable angle structure, which provides double fixation for the filter box 2 and ensures that the filter box 2 can be firmly fixed on the funnel 1 through the clamping part 3 and is not easy to fall off or shift.

[0042] In some embodiments of the present invention, referring to Figure 1 and Figure 3, the first fixing plate 31 is arranged perpendicularly to the side plate of the filter box 2, and the second fixing plate 32 is arranged parallel to the side plate of the filter box 2. In other words, the first fixing plate 31 and the second fixing plate 32 are arranged perpendicularly. In this way, the first fixing plate 31 and the second fixing plate 32 arranged perpendicularly to each other provide strong support for the filter box 2, ensuring that it will not shake or deform due to the flow of resin or the action of external force during use, thereby being able to effectively resist lateral force and impact force, and ensuring the stability of the filtering process.

[0043] In some embodiments of the present invention, referring to Figure 1 and Figure 2 The funnel 1 includes a first filter portion 11, and a second opening 111 is provided at the upper end of the first filter portion 11; the filter box 2 is arranged in the first filter portion 11 through the second opening 111, and the clamping portion 3 is clamped at the upper end of the bucket wall of the first filter portion 11, and the height of the filter box 2 is equal to or less than the height of the first filter portion 11. For example, referring to Figure 1 , Figure 2 and Figure 3 The height of the filter box 2 is the same as the height of the first filter part 11, wherein the material of the funnel 1 can be the same as that of the filter box 2, or different. In the present embodiment, the funnel 1 and the filter box 2 are both made of stainless steel. The filter box 2 is arranged in the first filter part 11 through the second opening 111, and the clamping part 3 is clamped on the upper end of the bucket wall of the first filter part 11, so that the replacement and cleaning of the filter box 2 becomes more convenient. When the filter box 2 needs to be cleaned or replaced, it can be easily taken out through the second opening 111 without disassembling the entire funnel 1, which greatly saves the operation time. The design of the clamping part 3 can ensure the stable installation of the filter box 2, and also prevent the filter box 2 from shifting or falling off during use, thereby ensuring the continuity and efficiency of the filtering process. At the same time, setting the height of the filter box 2 equal to or less than the height of the first filter part 11 is beneficial to simplifying the manufacturing process of the filter box 2, so that the filter box 2 is completely in the first filter part 11, preventing the upper end of the bucket wall of the funnel 1 from separating from the first fixed plate 31, thereby ensuring the stable installation of the filter box 2.

[0044] In some embodiments of the present invention, referring to Figure 1 and Figure 2The funnel 1 further includes a second filter portion 12. The lower end of the first filter portion 11 is connected to the second filter portion 12. The cross-sectional area of ​​the second filter portion 12 gradually decreases from the end close to the first filter portion 11 to the end away from the first filter portion 11. Exemplarily, the second filter portion 12 may be a cone with a rectangular cross section at the upper end and a circular cross section at the lower end. As the cross-sectional area of ​​the second filter portion 12 gradually decreases, the flow rate of the resin will gradually increase when it flows through the second funnel 1, so that the resin flows out faster in the second funnel 1, thereby improving the working efficiency of the funnel 1.

[0045] In some embodiments of the present invention, referring to Figure 1 and Figure 2 A transition pipe 13 is connected to the lower end of the second filter part 12, and the transition pipe 13 is used to connect the reflux pump through the reflux pipe. By connecting the filter box with the reflux pipe through the transition pipe 13, the installation and removal of the filter box can be easily realized, and the connection is more flexible, which is conducive to maintenance, replacement or cleaning operations.

[0046] In some embodiments of the present invention, referring to Figure 1 and Figure 2 The first filter part 11, the second filter part 12 and the transition pipe 13 are an integrated structure. In this way, the first filter part 11, the second filter part 12 and the transition pipe 13 are set as an integrated structure, so that there is no additional interface or gap at the connection between the three, thereby strengthening the stability of the entire structure, not prone to loosening or breaking, enhancing the overall structural strength of the funnel 1, and improving the durability and reliability of the funnel 1.
