Description

Technical Field

[0001] This utility model belongs to the field of glass fiber powder processing technology, specifically, it relates to a continuous processing device for surface modification of glass fiber powder. Background Technology

[0002] Glass fiber powder is a filler and reinforcing material made from continuous glass fiber filaments through chopping and grinding. The production process includes chopping, sieving, and modification treatment, which improves its compatibility with resin matrices. It is widely used as a reinforcing filler in composite materials such as plastics, rubber, and coatings. However, glass fiber powder has a large number of hydroxyl groups on its surface, making it highly polar. This results in poor compatibility with non-polar or weakly polar matrix materials, and direct addition can easily lead to uneven dispersion and weak interfacial bonding. Therefore, surface modification treatment is necessary.

[0003] When performing surface modification treatment of glass fiber powder, it is necessary to add a quantitative amount of glass fiber powder and modifier for mixing and reaction, and then discharge the material for the next batch of processing. However, in existing equipment, the modifier is mostly poured directly or simply sprayed, resulting in insufficient mixing and contact with the quantitatively added glass fiber powder. This leads to incomplete modification of some glass fiber powder, affecting the performance of subsequent composite materials.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A continuous processing device for surface modification of glass fiber powder includes a storage tank and a processing tank. The storage tank has a storage bin and a movable chamber inside. The storage bin has a discharge port at the bottom. A sealing seat is slidably disposed on the inner wall of the movable chamber. A guide port is provided on the sealing seat. A rotating shaft is rotatably mounted inside the movable chamber. A guide seat is fixedly connected to the outer wall of the rotating shaft. The guide seat is located on one side of the sealing seat. A drive motor is installed on the inner top of the movable chamber.

The top of the support springs is connected to the outer wall of the bottom of the support plate. Equally spaced atomizing nozzles are installed on both sides inside the processing box. The atomizing nozzles are located above the support plate.

[0006] In a preferred embodiment of the present invention, the top of the storage box is provided with a feed inlet, which is connected to the storage bin. A limiting frame is fixedly connected to the outer wall of the feed inlet, and a sealing plate is slidably provided on the inner side wall of the limiting frame, which is in contact with the top of the feed inlet.

[0007] In a preferred embodiment of this utility model, symmetrically arranged reset springs are installed on one side of the inner wall of the movable cavity, and one end of the reset spring is connected to the outer wall of one side of the sealing seat.

[0009] In a preferred embodiment of this utility model, symmetrically arranged infusion pipes are installed on the outside of the treatment box, and a branch pipe is connected to the end of the atomizing nozzle, and the branch pipe is connected to the infusion pipe.

[0010] In a preferred embodiment of this utility model, the infusion tube is connected to the same pipe joint at one end, and the pipe joint is connected to an inlet pipe, which is used to connect to a modifier storage tank equipped with a metering pump.

[0011] In a preferred embodiment of this utility model, a discharge pipe is installed on one side of the processing box, and the discharge pipe is used to connect to an external centrifugal separator.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0017] like Figures 1 to 5 As shown A continuous processing device for surface modification of glass fiber powder includes a storage tank 1 and a processing tank 2. The storage tank 1 has a storage silo 5 and a movable chamber 6 inside. An inlet 3 is located at the top of the storage tank 1 and is connected to the storage silo 5. A limit frame 12 is fixedly connected to the outer wall of the inlet 3. A sealing plate 13 is slidably arranged on the inner wall of the limit frame 12, and the sealing plate 13 contacts the top of the inlet 3. Glass fiber powder is fed into the storage silo 5 through the inlet 3. After feeding is completed, the sealing plate is pushed... 13 moves, causing the sealing plate 13 to contact the limiting frame 12, thus sealing the feed inlet 3. A discharge port 14 is provided at the bottom of the storage hopper 5. A sealing seat 7 is slidably mounted on the inner wall of the movable cavity 6. Symmetrically arranged return springs 11 are installed on one side of the inner wall of the movable cavity 6, with one end of each spring connected to the outer wall of the sealing seat 7. A guide port 15 is provided on the sealing seat 7, corresponding to the discharge port 14. A discharge pipe 4 is installed at the bottom of the storage box 1, and the discharge pipe 4 is connected to the processing box 2. The discharge pipe 4 is located directly below the discharge port 14. A rotating shaft 8 is rotatably installed inside the movable cavity 6. A guide seat 9 is fixedly connected to the outer wall of the rotating shaft 8. The guide seat 9 is located on one side of the sealing seat 7. A drive motor 10 is installed on the top inner side of the movable cavity 6. The output shaft of the drive motor 10 is connected to the top of the rotating shaft 8 through a coupling. After the glass fiber powder is stored in the storage bin 5, the drive motor 10 is started to drive the rotating shaft 8 to rotate. The rotating shaft 8 drives the guide seat 9 to rotate. When the guide seat 9 rotates to contact the sealing seat 7, it can push the sealing seat 7 to move, so that the guide port 15 opened on the sealing seat 7 moves to directly below the discharge port 14. At this time, the glass fiber powder in the storage bin 5 can be introduced into the discharge pipe 4 through the discharge port 14 and the guide port 15, and then fed into the processing box 2 through the discharge pipe 4. When the guide seat 9 is disengaged from the surface of the sealing seat 7, the sealing seat 7 can be pushed back to the initial position under the action of the return spring 11, so as to achieve the sealing effect of the discharge port 14 and achieve the effect of quantitative feeding.

[0018] In a specific embodiment, a support plate 16 is slidably arranged inside the processing box 2. A vibration motor 22 is installed at the bottom of the support plate 16. Symmetrically arranged support springs 23 are installed on both sides of the bottom of the processing box 2. The top of the support springs 23 is connected to the bottom outer wall of the support plate 16. Equally spaced atomizing nozzles 17 are installed on both sides inside the processing box 2. The atomizing nozzles 17 are located above the support plate 16. Symmetrically arranged infusion pipes 18 are installed on the outside of the processing box 2. The ends of the atomizing nozzles 17 are connected to branch pipes 19, which are connected to the infusion pipes 18. The opposite ends of the infusion pipes 18 are connected to the same pipe joint 20. An inlet pipe 21 is connected to the pipe joint 20. The inlet pipe 21 is used to connect to an external modifier storage tank equipped with a metering pump. When glass fiber powder is added... When the material is placed into the processing tank 2, the modifier in the modifier storage tank is quantitatively delivered to the atomizing nozzle 17 through the inlet pipe 21, pipe joint 20, delivery pipe 18 and branch pipe 19 by the metering pump. The atomizing nozzle 17 atomizes the modifier and sprays it evenly on the surface of the glass fiber powder. At the same time, the vibration motor 22 is started. The vibration motor 22, together with the set support spring 23, drives the support plate 16 to vibrate, so that the material on the support plate 16 is turned over and mixed, ensuring that the modifier and glass fiber powder are fully contacted and reacted. A discharge pipe 24 is installed on one side of the processing tank 2. The discharge pipe 24 is used to connect to an external centrifuge. The material after the modification reaction is completed enters the centrifuge through the discharge pipe 24. The centrifuge can separate the excess modifier (waste liquid) from the glass fiber powder in the material.

[0019] The implementation principle of the continuous processing device for surface modification of glass fiber powder in this embodiment is as follows: In specific use, glass fiber powder is fed into the storage bin 5 through the feed port 3. After feeding is completed, the sealing plate 13 is pushed to move, so that the sealing plate 13 contacts the limit frame 12 to achieve the sealing effect of the feed port 3. Then, the drive motor 10 is started to drive the rotating shaft 8 to rotate. The rotating shaft 8 drives the guide seat 9 to rotate. When the guide seat 9 rotates to contact the sealing seat 7, it can push the sealing seat 7 to move, so that the guide port 15 opened on the sealing seat 7 moves to the bottom port 14. At this time, the glass fiber powder in the storage bin 5 can be introduced into the feed pipe 4 through the feed port 14 and the guide port 15, and fed into the processing box 2 through the feed pipe 4. When the guide seat 9 is separated from the surface of the sealing seat 7, the sealing seat 7 can be pushed to the initial position under the action of the return spring 11 to achieve the sealing effect of the feed port 14 and achieve the effect of quantitative feeding. The inlet pipe 21 is connected to an external modifier storage tank equipped with a metering pump. When glass fiber powder is fed into the processing tank 2, the modifier in the storage tank is quantitatively delivered to the atomizing nozzle 17 through the inlet pipe 21, pipe joint 20, delivery pipe 18, and branch pipe 19 via the metering pump. The atomizing nozzle 17 atomizes the modifier and sprays it evenly onto the surface of the glass fiber powder. At the same time, the vibration motor 22 is started. The vibration motor 22, in conjunction with the support spring 23, drives the support plate 16 to vibrate, causing the modifier on the support plate 16 to vibrate. The material is agitated and mixed to ensure that the modifier and glass fiber powder are fully in contact and react. The material after the modification reaction is completed enters the centrifugal separator (existing technology) through the discharge pipe 24. The centrifugal separator separates the excess modifier (waste liquid) from the glass fiber powder. The separated glass fiber powder enters the hot air dryer (existing technology) to continuously dry the glass fiber powder. The dried finished glass fiber powder enters the finished product collection bin (existing technology) for storage, thus completing the entire continuous glass fiber powder surface modification process.
