Abstract
Description
Technical Field
[0001] This invention relates to the field of glass fiber treatment technology, and specifically discloses a device for improving the alkali resistance of chopped glass fibers for concrete. Background Technology
[0002] The chopped glass fibers used in concrete are all recycled glass fiber materials from the market. In their secondary utilization process, they need to be cleaned, dried, chopped, and then surface-treated to improve their alkali resistance before they can be used in concrete.
[0003] Currently, the main method for improving the alkali resistance of glass fiber is to immerse it in a zirconium salt + silane coupling agent treatment solution for a period of time. This allows the solution to react with the silanol groups on the glass fiber surface, forming a stable bridging protective layer through chemical bonding, thereby improving its alkali resistance. However, existing processing techniques and related equipment are primarily used for glass fiber filaments during the drawing and forming process. This involves drawing the drawn glass fiber filaments through a treatment solution tank, bringing them into contact with the solution, and then using scrapers, sponges, and other components to remove excess solution from the surface of the glass fiber filaments before they are pulled out, preventing significant loss of the solution and increased processing costs. However, recycled glass fiber cannot undergo the same alkali resistance improvement treatment as glass fiber drawing and forming processes.
[0004] Currently, the industry typically uses a metal mesh frame to load chopped glass fibers in one go, immerses them in a treatment solution for a period of time, and then uses hoisting equipment to lift them and let them stand for a while, allowing excess treatment solution to drain and fall back into the treatment tank, thus reducing the amount of treatment solution used. However, the above process is limited by equipment limitations. It requires manual loading and unloading, the entire process is discontinuous, and the time for draining excess treatment solution usually takes more than 10 minutes, increasing the overall processing time for chopped glass fibers. Therefore, to address the shortcomings of existing methods for improving the alkali resistance of recycled chopped glass fibers through impregnation treatment, this application proposes a treatment device for improving the alkali resistance of chopped glass fibers for concrete that enables continuous batch production, automatic loading and unloading, and rapid discharge of excess treatment solution. Summary of the Invention
[0005] The present invention aims to provide a treatment device for improving the alkali resistance of chopped glass fibers for concrete, so as to realize continuous batch production, automatic loading and unloading, and rapid discharge of excess treatment liquid in the process of impregnating recycled chopped glass fibers to improve their alkali resistance, thereby improving the treatment efficiency of improving the alkali resistance of chopped glass fibers.
[0006] This invention is achieved through the following technical solution: A device for improving the alkali resistance of chopped glass fiber for concrete includes an impregnation tank. The impregnation tank is provided with vertical plates at both ends. A loading drum assembly with its lower end extending into the treatment liquid is rotatably connected between the two vertical plates. A rotational power component is connected to the loading drum assembly. The loading drum assembly includes front and rear side plates. The outer edge between the two side plates is divided into multiple loading zones by an inner ring plate and multiple partitions. Each loading zone has a sealing plate at its opening end. The side end of the sealing plate is connected to a rotating bar located outside the side plate via a pin. The end of the rotating bar is connected to a guide wheel. Each loading zone is provided with a telescopic push plate whose two ends are always in contact with the partitions on both sides during radial movement. A radial rod passing through the inner ring plate is connected to the telescopic push plate. The inner end of the radial rod is connected to an abutment wheel, and a return spring is connected between the radial rod and the inner ring plate. The loading drum assembly has a concentrically arranged irregularly shaped cam that interacts with the abutment wheel in the middle cavity, and the irregularly shaped cam is fixedly connected to the vertical plate. The two vertical plates have concentrically opened irregularly shaped annular grooves that interact with the guide wheel on their opposite sides.
[0007] As a further feature of the above scheme, the profile surface of the irregular cam includes a small arc surface and a large arc surface, which are connected by a transition surface, and the large arc surface is set towards the discharge side of the immersion treatment tank. The irregular annular groove includes an arc segment and two convex segments. One convex segment is located above the large arc surface, and the other convex segment is located on the upper half of the opposite vertical plate.
[0008] As a further feature of the above scheme, a downwardly inclined guide trough is provided on the impregnation treatment tank located below the large arc surface.
[0009] As a further provision of the above scheme, the side plate is in the shape of a regular polygon or a circle, the inner ring plate is also in the shape of a regular polygon or a circle, and the inner ring plate is concentrically arranged between the two side plates, and a plurality of the partitions are evenly arranged on the inner ring plate and extend radially outward.
[0010] As a further feature of the above scheme, a power shaft and a hollow shaft are respectively connected to the center of the two side plates, and the power shaft and the hollow shaft are rotatably connected to the bearings on the two upright plates. The outer end of the power shaft extending out of the side plate is connected to the rotating power assembly.
[0011] As a further feature of the above scheme, the irregular cam is provided with fixing rods at both the front and rear ends. The fixing rod on the front side is rotatably connected to the center of the side plate through a bearing, and the fixing rod on the rear side passes through the hollow shaft and is fixedly connected to the connecting frame on the vertical plate.
[0012] As a further feature of the above scheme, the telescopic push plate includes a hollow plate connected to a radial rod. Movable plates with outer ends that fit against a partition are inserted into both ends of the hollow plate. The inner ends of the two movable plates are connected to an elastic support member.
[0013] As a further provision of the above scheme, an aeration pipe is provided in the impregnation treatment tank located directly below the loading drum assembly, and an aeration head is connected to the upper end of the aeration pipe. A blower located outside the impregnation treatment tank is connected to the aeration pipe.
[0014] As a further provision of the above scheme, an air heater is connected to the air outlet of the blower, and the air outlet of the air heater is connected to the end of the aeration pipe that extends out of the immersion treatment tank.
[0015] In the operation of the concrete chopped glass fiber alkali resistance enhancement treatment equipment disclosed in this invention, the loading drum assembly can stably rotate at a set speed at the upper end of the impregnation treatment tank under the action of the rotation power component. During the rotation of the loading drum assembly, the abutting wheel can abut against the irregular cam, and the guide wheel can interact with the irregular ring groove.
[0016] During the feeding stage, the guide wheel corresponding to the feeding area interacts with the protruding section on the irregular ring groove, and then the sealing plate rotates around the pin shaft under the action of the rotating bar and the pin shaft, thereby opening the opening end of the feeding area. At this time, the short glass fiber is quantitatively added to the feeding area by the matching feeding machine.
[0017] After the material is loaded, the loading area rotates downwards. At this time, due to the interaction between the guide wheel and the arc segment on the irregular ring groove, the sealing plate closes again at the opening end of the loading area to seal it. After sealing, it rotates to the bottom and is immersed in the treatment solution in the impregnation tank. At the same time, under the action of the blower, air heater and aeration pipe, heated air is continuously sprayed out from the aeration head, causing the treatment solution directly below the loading area to continuously surge upwards and stir the chopped glass fibers in the loading area, so as to carry out rapid and thorough surface treatment on the chopped glass fibers.
[0018] After the chopped glass fiber surface treatment is completed, the loading area will start to rotate upward. During its upward rotation, the abutment wheel will start to interact with the transition surface on the irregular cam, causing the telescopic pusher to move radially outward. When the abutment wheel interacts with the large arc surface, the radial push of the telescopic pusher, combined with the limiting effect of the sealing plate, will squeeze the treated chopped glass fiber and drain the excess treatment liquid from the chopped glass fiber.
[0019] Finally, when the guide wheel interacts with another convex section, the opening of the loading area will be opened under the action of the guide wheel and the convex section. At this time, the chopped glass fiber inside is pushed out of the loading area by the telescopic push plate and finally received by the guide trough.
[0020] Compared with the prior art, the present invention has the following beneficial effects: The alkali resistance enhancement treatment equipment for chopped glass fibers used in concrete disclosed in this invention utilizes the rotation process of the loading drum assembly. First, the loading area opening is opened for easy material feeding. Then, the opening is automatically closed and the assembly rotates downwards, immersing the chopped glass fibers in a treatment liquid for surface treatment. After treatment, during upward rotation, the radial movement of the telescopic pusher plate further squeezes and drains the chopped glass fibers. After draining, the loading area automatically opens again, and the telescopic pusher plate facilitates automatic unloading. The entire treatment equipment features an ingenious structural design. Through the rotation of the loading drum, the processes of feeding, immersion, squeezing and dehydration, and unloading are completed sequentially, achieving fully automated processing for enhancing the alkali resistance of chopped glass fibers used in concrete and effectively improving the surface treatment efficiency of the chopped glass fibers.
[0021] The present invention further includes an aeration component in the impregnation treatment tank. Heated air can be introduced into the treatment liquid using a blower and an air heater. The heated air causes the treatment liquid to churn, allowing the chopped glass fibers in the loading area to quickly and fully contact the treatment liquid and complete the surface treatment. In addition, the heated air raises the temperature of the treatment liquid, improving the efficiency of the alkali-resistant surface treatment of the chopped glass fibers and ensuring the alkali resistance of the chopped glass fibers obtained after treatment.

Detailed Implementation
[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-7 This application will be described in detail with reference to the embodiments. Example 1
[0026] Example 1 discloses a device for improving the alkali resistance of chopped glass fibers for concrete, as shown in the attached figure. Figures 1-3 The system includes an impregnation tank 1 and a loading drum assembly 2. Upwardly extending vertical plates 3 are integrally formed on the front and rear sides of the impregnation tank 1, and the loading drum assembly 2 is rotatably connected between the two vertical plates 3. A rotational power assembly 4 for driving the loading drum assembly 2 is also provided on the outer sides of the impregnation tank 1 and the vertical plates 3, so that during the rotation of the loading drum assembly 2, the chopped glass fibers filled inside it can be sequentially immersed into the treatment liquid of the impregnation tank 1 as they pass the bottom.
[0027] Reference Appendix Figures 3-7The loading drum assembly 2 has two side plates 201 that are regular polygons or circles. Inside the two side plates 201, there are concentric inner ring plates 202 that are regular polygons or circles. In this figure, the side plates 201 and inner ring plates 202 are regular octagons. Then, multiple radially outwardly extending partitions 203 are evenly arranged on the inner ring plates 202, so that the annular space outside the inner ring plates 202 is divided into multiple loading areas 200 under the action of the multiple partitions 203. A sealing plate 204 is rotatably connected to the radially outer opening end of each loading area 200. The length of the filter holes on the sealing plate 204 is set to be less than the length of the chopped glass fiber to prevent the chopped glass fiber from easily leaking out through the sealing plate 204. In the specific design, the sealing plate 204 is rotatably connected to the opening end of the loading area 200 by a pin on one side, and both ends of the pin extend out of the front and rear upright plates 3. Then, a rotating bar 205 is fixedly connected to the outer end of the pin, and a guide wheel 206 is provided at the movable end of the rotating bar 205.
[0028] Each inner ring plate 202 is provided with a telescopic push plate 207. The two ends of the telescopic push plate 207 are always in contact with the partition plates 203 on both sides during radial movement. In a specific design, the telescopic push plate 207 includes a hollow plate 2071. A movable plate 2072 is inserted into both ends of the hollow plate 2071. The movable plate 2072 extends out of the outer end of the hollow plate 2071 and is in contact with the partition plate 203. Then, an elastic support member 2073 is connected to the inner end of the two movable plates 2072. The elastic support member 2073 can be a bent metal plate or a spring, etc.
[0029] A radial rod 208 is connected to the hollow plate 2071, which extends radially through the inner ring plate 202 and into the middle cavity of the loading drum assembly 2. An abutment wheel 209 is connected to the end of the radial rod 208. An end plate 210 is fixed on the radial rod 208 near the abutment wheel 209. A return spring 211 is connected between the end plate 210 and the inner ring plate 202.
[0030] In addition, a power shaft 212 and a hollow shaft 213 are respectively connected to the center of the two side plates 201. The power shaft 212 and the hollow shaft 213 are rotatably connected to bearings on the two vertical plates 3. Then, the rotating power assembly 4 is connected to the outer end of the power shaft 212. Specifically, the rotating power assembly 4 includes a power motor 401. A transmission wheel 402 is provided on both the motor shaft of the power motor 401 and the outer end of the power shaft 212. Then, a transmission belt 403 is provided between the two transmission wheels 402, so that under the combined action of the power motor 401 and the transmission belt 403, the loading drum assembly 2 rotates stably around the power shaft 212 at a set speed.
[0031] Reference Appendix Figure 3 and attached Figure 5 A shaped cam 5, which interacts with the abutment wheel 209, is concentrically arranged in the central cavity of the loading drum assembly 2. A fixing rod 501 is concentrically arranged on both the front and rear ends of the shaped cam 5. The front fixing rod 501 is rotatably connected to the center of the side plate 201 via a bearing, while the rear fixing rod 501 passes through the hollow shaft 213 and is fixedly connected to the connecting frame 301 on the vertical plate 3. The contour surface of the shaped cam 5 includes a small arc surface 502 and a large arc surface 503, which are connected by a transition surface 504. The large arc surface 503 faces the discharge side of the impregnation treatment tank 1. A downwardly inclined guide groove 100 is also provided on the impregnation treatment tank 1 below the large arc surface 503.
[0032] On the opposite sides of the two vertical plates 3, irregularly shaped annular grooves 300 are provided, concentrically arranged with the loading drum assembly 2, and all guide wheels 206 on the loading drum assembly 2 interact with the irregularly shaped annular grooves 300. The irregularly shaped annular grooves 300 include an arc segment 3001 and two convex segments 3002, one of which is located above the large arc surface 503, and the other is located on the upper half of the opposite side.
[0033] In the operation of the concrete chopped glass fiber alkali resistance enhancement treatment equipment disclosed in Embodiment 1, when the loading area 200 rotates and moves to the position of the upper convex section 3002, under the action of the guide wheel 206 and the convex section 3002, the corresponding sealing plate 204 will rotate and open from the opening end of the loading area 200. At this time, the concrete chopped glass fiber can be quantitatively added to the loading area 200 through the feeding equipment.
[0034] After feeding is completed, the drum continues to rotate, and the guide wheel 206 interacts with the arc segment 3001, causing the sealing plate 204 to press against the open end of the loading area 200, preventing the chopped glass fibers from leaking out of the loading area 200 during the downward rotation of the loading drum assembly 2. When the loading area 200 containing the chopped glass fibers rotates to the bottom, the treatment liquid in the impregnation tank 1 will enter the loading area 200 through the sealing plate 204 and fully mix and contact with the chopped glass fibers, completing the surface modification treatment of the chopped glass fibers.
[0035] Subsequently, as the loading area 200 rotates upward from the bottom, the abutment wheel 209 begins to interact with the transition surface 504 on the irregular cam 5, causing the telescopic push plate 207 to move radially outward. When the abutment wheel 209 interacts with the large arc surface 503, the radial push of the telescopic push plate 207, combined with the limiting effect of the sealing orifice plate 204, can squeeze the processed chopped glass fibers and drain the excess processing liquid from the chopped glass fibers.
[0036] Finally, when the guide wheel 206 interacts with another protruding section 3002, the opening end of the loading area 200 will be opened under the action of the guide wheel 206 and the protruding section 3002. At this time, due to the pushing action of the telescopic push plate 207, the chopped glass fibers after the dewatering is completed will be pushed out from the loading area 200 and finally received by the guide trough 100 and collected in a centralized manner. The alkali resistance improvement treatment of chopped glass fibers for concrete can be completed automatically throughout the entire process. Example 2
[0037] Example 2 discloses a concrete chopped glass fiber alkali resistance enhancement treatment device that is further optimized based on the technical solution in Example 1. The similarities with Example 1 will not be described again.
[0038] Reference Appendix Figure 2 and attached Figure 3 In this embodiment 2, an aeration pipe 6 is installed in the impregnation treatment tank 1 directly below the loading drum assembly 2. The aeration pipe 6 is composed of an outer rectangular tube and multiple longitudinal connecting pipes arranged in the middle. Multiple aeration heads 601 are evenly arranged on the aeration pipe 6. A blower 7 is installed on the outer side of the impregnation treatment tank 1. An air heater 8 is connected to the air outlet of the blower 7. The air outlet of the air heater 8 is then connected to the end of the aeration pipe 6 that extends out of the impregnation treatment tank 1.
[0039] In addition, in this embodiment 2, a level gauge and a temperature sensor (not shown in the figure) are installed in the immersion treatment tank 1, and both are connected to the controller of the whole device. The level gauge can detect the level of the internal treatment liquid in real time and replenish it in time, while the temperature sensor can detect the temperature of the treatment liquid in real time to ensure that the temperature of the treatment liquid is within the optimal range.
[0040] In this embodiment 2, through the above-mentioned improved design, when the loading zone 200 carrying the chopped glass fibers rotates to the bottom, the loading zone 200 can be aligned vertically with the aeration pipe 6. Then, heating gas can be continuously introduced into the treatment liquid through the aeration head 601 and the air heater 8, so that the treatment liquid below the loading zone 200 continuously churns and enters the loading zone 200 to contact the chopped glass fibers, thereby accelerating the treatment speed and effect of the treatment liquid on the chopped glass fibers.
[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
