Abstract
Description
Technical Field
[0001] The invention relates to the technical field of glass fiber processing, and in particular discloses a processing device for improving the alkali resistance of chopped glass fibers for concrete. Background Art
[0002] The chopped glass fibers used in concrete are all recycled glass fibers from the market. During their secondary use, they need to be cleaned, dried, chopped, and then surface treated to improve their alkali resistance before they can be used in concrete.
[0003] At present, the main method to improve the alkali resistance of glass fiber is to immerse it in a zirconium salt + silane coupling agent treatment solution for a period of time, so that it can react with the silanol group on the surface of the glass fiber, and form a stable bridge protection layer on the surface of the glass fiber through chemical bonding, thereby improving its alkali resistance. However, the existing treatment process and related equipment are mainly used to treat glass fiber filaments in the wire drawing process, that is, the wire drawing glass fiber filaments are pulled through the treatment liquid tank so that they come into contact with the treatment liquid. Then, before being pulled out of the treatment liquid tank, scrapers, sponges and other components are used to clean up the excess treatment liquid attached to the surface of the glass fiber filaments to avoid serious loss of treatment liquid, which in turn leads to increased processing costs. As recycled glass fiber, it cannot be pulled through the treatment tank to complete the alkali resistance improvement treatment in the same way as the glass fiber wire drawing process.
[0004] At present, the industry usually directly uses a metal mesh frame to load chopped glass fibers at one time, immerses it in the treatment liquid for a period of time, and then uses a lifting equipment to lift it and let it stand for a period of time, so that the excess treatment liquid drains during the standing process and falls back into the treatment tank to reduce the amount of treatment liquid used. However, the above-mentioned treatment process is limited by the shortcomings of the equipment. Not only does it require manual loading and unloading, the entire treatment process is discontinuous, and the time for standing and draining the excess treatment liquid usually takes more than 10 minutes, which increases the entire treatment time of the chopped glass fibers. Therefore, in response to the shortcomings of the existing impregnation treatment of chopped glass fiber recycled materials to improve alkali resistance, the present application proposes a chopped glass fiber for concrete alkali resistance improvement treatment equipment that can achieve batch continuous production, automatic loading and unloading, and rapid discharge of excess treatment liquid. 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 batch continuous production, automatic loading and unloading, rapid discharge of excess treatment liquid, etc. in the process of impregnating chopped glass fiber recycled materials to improve the alkali resistance, thereby improving the treatment efficiency of improving the alkali resistance of chopped glass fibers.
[0006] The present invention is achieved through the following technical solutions: A device for improving the alkali resistance of chopped glass fibers for concrete comprises an immersion treatment tank, wherein vertical plates are provided at both the front and rear ends of the immersion treatment tank, a loading drum assembly is rotatably connected between the two vertical plates, and a rotating power component is connected to the loading drum assembly; The charging drum assembly includes two front and rear side plates, and the outer edge between the two side plates is equally divided into multiple charging areas by an inner ring plate and a plurality of partitions. The open end of each charging area is provided with a sealing orifice plate, and the side end of the sealing orifice plate is connected to a rotating bar located on the outer side of the side plate through a pin shaft, and the end of the rotating bar is connected to a guide wheel. A telescopic push plate is provided in each of the charging areas, and the two ends of the telescopic push plate are always in contact with the partitions on both sides during the radial movement. A radial rod passing through the inner ring plate is connected to the telescopic push plate, and the inner end of the radial rod is connected to the abutment wheel, and a return spring is connected between the radial rod and the inner ring plate; A special-shaped cam that acts on the abutment wheel is concentrically arranged in the middle cavity of the charging drum assembly, and the special-shaped cam is fixedly connected to the vertical plate. Special-shaped annular grooves that act on the guide wheel are concentrically opened on the opposite sides of the two vertical plates.
[0007] As a further configuration of the above solution, the contour surface of the special-shaped cam includes a small arc surface and a large arc surface, the small arc surface and the large arc surface are connected by a transition surface, and the large arc surface is arranged toward the discharge side of the immersion treatment tank; The special-shaped annular groove includes an arc segment and two convex segments, wherein one convex segment is arranged above the large arc surface, and the other convex segment is arranged on the upper half of the vertical plate on the opposite side.
[0008] As a further configuration of the above solution, a downwardly inclined material guide trough is provided on the immersion treatment tank located below the large arc surface.
[0009] As a further configuration of the above scheme, the side plates are regular polygonal or circular, the inner ring plate is also regular polygonal or circular, and the inner ring plate is concentrically arranged between the two side plates, and the plurality of partitions are evenly arranged on the inner ring plate and extend radially outward.
[0010] As a further arrangement of the above scheme, a power shaft and a hollow shaft are respectively connected to the centers of the two side plates, and the power shaft and the hollow shaft are respectively rotatably connected to the bearings on the two vertical plates, and the power shaft extends out of the outer end of the side plate and is connected to the rotating power component.
[0011] As a further arrangement of the above scheme, fixed rods are provided at both the front and rear ends of the special-shaped cam. The front fixed rod is rotatably connected to the center of the side plate through a bearing, and the rear fixed rod passes through a hollow shaft and is fixedly connected to the connecting frame on the vertical plate.
[0012] As a further configuration of the above scheme, the telescopic push plate includes a hollow plate connected to the radial rod, and both side ends of the hollow plate are connected with movable plates whose outer ends are in contact with the partition, and the inner ends of the two movable plates are commonly connected with an elastic support member.
[0013] As a further configuration of the above solution, an aeration pipe is provided in the immersion treatment tank directly below the charging drum assembly, and an aeration head is connected to the upper end of the aeration pipe, and the aeration pipe is connected to a blower located outside the immersion treatment tank.
[0014] As a further configuration of the above solution, the air outlet end of the blower is connected to an air heater, and the air outlet end of the air heater is connected to the end of the aeration pipe extending out of the immersion treatment tank.
[0015] During the operation of the alkali resistance improving treatment equipment for chopped glass fibers for concrete disclosed in the present invention, the loading drum assembly can stably rotate at a set speed at the upper end of the immersion treatment tank under the action of the rotating power component, and during the rotation of the loading drum assembly, the abutment wheel can abut against the special-shaped cam, and the guide wheel can interact with the special-shaped annular groove.
[0016] During the loading stage, the guide wheel corresponding to the loading area interacts with the outer convex section on the special-shaped ring groove, and then the sealing orifice plate can rotate around the pin shaft under the action of the rotating bar and the pin shaft, thereby opening the open end of the loading area. At this time, the chopped glass fiber is quantitatively added into the loading area through the matching loader.
[0017] After loading is complete, the loading area rotates downward. At this point, the guide wheel interacts with the arc segment of the special-shaped ring groove, causing the sealing orifice plate to close again on the open end of the loading area to seal it. After sealing, it rotates to the bottom and immerses itself in the treatment liquid in the immersion treatment tank. At the same time, the blower, air heater, and aeration pipe cause heated air to be continuously ejected from the aeration head, causing the treatment liquid directly below the loading area to continuously surge upward and stir the chopped glass fibers in the loading area, allowing them to quickly and fully treat the surface of the chopped glass fibers.
[0018] When the surface treatment of the chopped glass fibers is completed, the loading area will begin to rotate upward, and during its upward rotation, the abutment wheel will begin to act on the transition surface on the special-shaped cam, causing the telescopic push plate to move radially outward until the abutment wheel acts on the large arc surface. Through the radial push of the telescopic push plate and the limiting effect of the sealing orifice plate, the treated chopped glass fibers can be squeezed and the excess treatment liquid in the chopped glass fibers can be drained.
[0019] Finally, when the guide wheel interacts with another convex section, the open end of the loading area will be opened under the action of the guide wheel and the convex section. At this time, the internal chopped glass fiber is pushed out of the loading area due to the push of 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 improving treatment equipment for chopped glass fibers for concrete disclosed by the present invention can, through the rotation process of the loading drum assembly, first open the opening of the loading area to facilitate feeding, and then automatically close the opening and rotate downward, thereby immersing the chopped glass fibers in the treatment liquid for surface treatment. After the treatment is completed, the chopped glass fibers can be squeezed and drained by the radial movement of the telescopic push plate during the upward rotation process. After the drainage is completed, the loading area is automatically opened, and automatic unloading is achieved under the action of the telescopic push plate. The structural design of the entire treatment equipment is ingenious. Through the rotation of the loading drum, the processes of loading, impregnation, squeezing dehydration and unloading can be completed in sequence, thereby realizing the full automation of the alkali resistance improving treatment of the chopped glass fibers for concrete, and effectively improving the surface treatment efficiency of the chopped glass fibers.
[0021] The present invention further provides an aeration assembly in the impregnation treatment tank, and heated air can be introduced into the treatment liquid by using a blower and an air heater. The heated air, on the one hand, causes the treatment liquid to churn, so that the chopped glass fibers in the loading area can quickly and comprehensively contact the treatment liquid and complete the surface treatment. On the other hand, the heated air will cause the treatment liquid to heat up, thereby 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 DESCRIPTION
[0024] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.
[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. Figures 1 to 7 , and describes the application in detail with reference to embodiments. Example 1
[0026] Example 1 discloses a device for improving the alkali resistance of chopped glass fibers for concrete. Figures 1-3 The immersion treatment tank 1 and the charging drum assembly 2 are provided with an integral structure with upwardly extending vertical plates 3 on the front and rear sides of the immersion treatment tank 1. The charging drum assembly 2 is rotatably connected between the two vertical plates 3. A rotating power assembly 4 for driving the charging drum assembly 2 is also provided on the outer sides of the immersion treatment tank 1 and the vertical plates 3. As the charging drum assembly 2 rotates, the chopped glass fibers filled therein are sequentially immersed in the treatment liquid in the immersion treatment tank 1 as they pass the bottom.
[0027] Reference Attachment Figures 3 to 7The charging drum assembly 2 has two front and rear side plates 201 in the form of regular polygons or circles, and an inner ring plate 202 in the form of regular polygons or circles is concentrically arranged inside the two side plates 201. The side plates 201 and the inner ring plate 202 in this figure are regular octagons, and then a plurality of radially outwardly extending partitions 203 are evenly arranged on the inner ring plate 202, so that under the action of the plurality of partitions 203, the annular space outside the inner ring plate 202 is equally divided into a plurality of charging areas 200, and a sealing orifice plate 204 is rotatably connected to the radially outer open end of each charging area 200, and the filter hole length on the sealing orifice plate 204 is set to be smaller than the length of the chopped glass fiber to prevent the chopped glass fiber from easily leaking through the sealing orifice plate 204. In the specific design, the sealing orifice plate 204 is rotatably connected to the open end of the loading area 200 through a pin shaft at one end, and both ends of the pin shaft extend out of the front and rear vertical plates 3, and then a rotating bar 205 is fixedly connected to the outer end of the pin shaft, 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 retractable push plate 207. The two ends of the retractable push plate 207 are able to always fit in contact with the partitions 203 on either side during radial movement. Specifically, the retractable push plate 207 comprises a hollow plate 2071, with a movable plate 2072 inserted at each end of the hollow plate 2071. The movable plate 2072 extends outward from the hollow plate 2071 to fit in contact with the partitions 203. An elastic expansion member 2073 is connected to the inner ends of the two movable plates 2072. The elastic expansion member 2073 can be a bent metal plate or a spring.
[0029] A radial rod 208 is connected to the hollow plate 2071 and radially passes through the inner ring plate 202 to extend into the middle cavity of the charging drum assembly 2, and an abutment wheel 209 is connected to the end of the radial rod 208. At the same time, an end plate 210 is fixed to the radial rod 208 on the side close to the abutment wheel 209, and 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 connected to the centers of the two side plates 201, respectively. The power shaft 212 and the hollow shaft 213 are respectively rotatably connected to the bearings on the two vertical plates 3, and 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, and transmission wheels 402 are provided on 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 charging drum assembly 2 rotates stably around the power shaft 212 at a set speed.
[0031] Reference Attachment Figure 3 and attached Figure 5 A special-shaped cam 5 is concentrically disposed in the central cavity of the charging drum assembly 2, interacting with the abutment wheel 209. Fixed rods 501 are concentrically disposed on both the front and rear ends of the special-shaped cam 5. The front fixed rod 501 is rotatably connected to the center of the side plate 201 via a bearing, while the rear fixed rod 501 passes through the hollow shaft 213 and is fixedly connected to the connecting bracket 301 on the vertical plate 3. The profile of the special-shaped cam 5 includes a small arc surface 502 and a large arc surface 503. The small arc surface 502 and the large arc surface 503 are connected by a transition surface 504. The large arc surface 503 is positioned toward the discharge side of the immersion tank 1. A downwardly inclined material guide trough 100 is also disposed on the immersion tank 1 below the large arc surface 503.
[0032] On opposite sides of the two vertical plates 3, a special-shaped annular groove 300 is formed, which is concentric with the charging drum assembly 2. All guide wheels 206 on the charging drum assembly 2 interact with the special-shaped annular groove 300. The special-shaped annular groove 300 includes an arc segment 3001 and two convex segments 3002. One convex segment 3002 is located above the large arc surface 503, and the other convex segment 3002 is located in the upper half of the opposite side.
[0033] During the operation of the alkali resistance improving treatment equipment for chopped glass fibers for concrete disclosed in this 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 orifice plate 204 will rotate and open from the open end of the loading area 200. At this time, the chopped glass fibers for concrete can be quantitatively added into the loading area 200 through the loading equipment.
[0034] After the feeding is completed, the drum assembly 200 continues to rotate, and the guide wheel 206 interacts with the arc segment 3001 to press the sealing plate 204 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 filled with chopped glass fibers rotates to the lowest point, the treatment liquid in the immersion treatment tank 1 will enter the loading area 200 through the sealing plate 204, fully mixing and contacting the chopped glass fibers, completing the surface modification of the chopped glass fibers.
[0035] Subsequently, during the process of the loading area 200 rotating upward from the bottom, the abutment wheel 209 begins to interact with the transition surface 504 on the special-shaped cam 5, thereby causing the telescopic push plate 207 to move radially outward until the abutment wheel 209 interacts with the large arc surface 503. Through the radial push of the telescopic push plate 207 and the limiting effect of the sealing hole plate 204, the processed chopped glass fibers can be squeezed and the excess processing liquid in the chopped glass fibers can be drained.
[0036] Finally, when the guide wheel 206 interacts with another convex section 3002, the open end of the loading area 200 will also be opened under the action of the guide wheel 206 and the convex section 3002. At this time, due to the pushing action of the telescopic push plate 207, the chopped glass fibers after drainage will be pushed out from the loading area 200, and finally received by the guide trough 100 and collected in a centralized manner, thereby automatically completing the alkali resistance improvement treatment of the chopped glass fibers for concrete. Example 2
[0037] Example 2 discloses a alkali resistance improvement treatment device for chopped glass fibers for concrete that is further optimized based on the technical solution in Example 1. The similarities with Example 1 will not be described again.
[0038] Reference Attachment Figure 2 and attached Figure 3 In this embodiment 2, an aeration pipe 6 is installed in the immersion treatment tank 1 directly below the charging drum assembly 2. The aeration pipe 6 is composed of a rectangular outer tube and multiple longitudinal connecting tubes 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 immersion treatment tank 1. The air outlet of the blower 7 is connected to an air heater 8, which is then connected to the end of the aeration pipe 6 extending from the immersion treatment tank 1.
[0039] In addition, in this embodiment 2, a liquid level meter and a temperature sensor (not shown) are installed in the immersion treatment tank 1, and both are connected to the controller of the entire device. The liquid level meter can detect the liquid 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 temperature.
[0040] In the second embodiment, through the above-mentioned improved design, when the loading area 200 carrying the chopped glass fibers rotates to the lowest end, the loading area 200 can be aligned with the aeration pipe 6 up and down, and then heated 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 area 200 is continuously churned and enters the loading area 200 to contact the chopped glass fibers, thereby accelerating the treatment speed and treatment effect of the treatment liquid on the chopped glass fibers.
[0041] The above are only 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 in the scope of protection of the present invention.
