Description

Technical Field

[0001] This utility model relates to the field of glass fiber crushing technology, and in particular to an alkali-free glass fiber crushing device. Background Technology

[0002] Glass fiber is a high-performance inorganic non-metallic material. Its production process requires crushing the raw glass material, melting it at high temperatures, and then further processing. Therefore, an existing glass fiber raw material crushing device (publication number CN221656681U) involves two rotating crushing rollers that crush the raw material fed from above the crushing chamber. The crushed material falls onto the inner side of a hopper-shaped screen plate for sieving. During this process, a rotating rod drives a cam to rotate, causing a contact plate to reciprocate. The contact plate, through a connecting rod, drives a sliding plate and the hopper-shaped screen plate to reciprocate. As the hopper-shaped screen plate vibrates left and right, a baffle is horizontally positioned to continuously contact and block the bottom of the hopper-shaped screen plate, preventing incompletely crushed material from leaving. After crushing and sieving, rotating a knob moves a threaded rod, causing the baffle to move backward until it no longer blocks the bottom of the hopper-shaped screen plate. At this point, any remaining incompletely crushed material inside the hopper-shaped screen plate is discharged from the bottom.

[0003] However, the incompletely crushed material that is screened out needs to be collected a second time and crushed again. However, because the glass fiber itself is relatively fine and will be even shorter after being crushed once, personnel need to take precautions to prevent accidental contact during the collection process. Therefore, personnel need to be careful when operating, which makes the collection process time-consuming. Moreover, the equipment must be stopped during the collection process, which also affects the crushing efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing an alkali-free glass fiber crushing device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an alkali-free glass fiber pulverizing device, comprising a shell, a pulverizing barrel fixedly installed inside the shell, and an inclined filter plate movably installed below the pulverizing barrel inside the shell. A storage tank is fixedly installed at the bottom edge of the outer wall of the shell, and a connecting cover fixedly installed on the outside of the shell is installed at the opening of the storage tank. The opening of the connecting cover extends into the shell and is at the same height as the bottom edge of the filter plate. A collecting shell is fixedly installed at the top edge of the outer surface of the shell on the same side as the storage tank, and an exhaust fan is installed on the collecting shell. The air inlet is connected to the inside of the collection shell and is equipped with filter cotton. A dust suction pipe is installed on the side of the collection shell where it communicates with the exhaust fan. The air inlet of the dust suction pipe extends downward through the side of the storage tank and is gap-fitted with the center of the bottom surface of the storage tank. An inner box that communicates with the air inlet of the exhaust fan is fixedly installed inside the collection shell. A door panel is inserted into the inner box, and a channel extending into the crushing barrel is installed on the bottom edge of the collection box wall. A chamber that communicates with the channel is provided inside the collection shell, and the opening of the chamber is located at the bottom edge of the inner box wall. The bottom of the chamber is inclined, and a sealing plate for sealing the opening is inserted into the bottom of the chamber.

[0006] Preferably, the crushing barrel is provided with a crushing blade, and the blade rod at the center of the crushing blade penetrates downward through the filter plate and is fixedly installed with a lever. A spring rod is provided between the bottom corner of the filter plate and the bottom surface of the outer shell, and a connecting block for sliding connection with the lever is fixedly installed on the bottom surface of the filter plate.

[0007] Preferably, the inner bottom surface of the outer shell is sloped below the filter plate, and a collection box is provided on the outside of the outer shell. The opening of the collection box is inserted into the side wall of the outer shell and is distributed at the same height as the lower edge of the slope of the inner bottom surface of the outer shell.

[0008] Preferably, a sealing strip is slidably installed on the opening of the connecting cover, and an electric push rod for pushing the sealing strip is fixedly installed on the side of the connecting cover facing away from the outer shell. The opening of the storage tank is connected to the middle position of the inner bottom surface of the connecting cover.

[0009] Preferably, the exhaust fan outlet is located outside the collection shell and is equipped with an air guide shroud, and the air guide shroud outlet end is equipped with a blower pipe fixedly installed at the mouth of the crushing barrel.

[0010] Preferably, the bottom of the storage tank is recessed and conical at the center, and a ventilation opening is provided on the surface of the storage tank near the opening.

[0011] Preferably, a horizontally arranged electric telescopic rod is fixedly installed inside the collection shell, and a horizontal spring rod is fixedly installed on the telescopic end of the electric telescopic rod, which is coaxially distributed and fixedly connected to the side of the door panel. A push block is fixedly installed on the cylinder of the horizontal spring rod.

[0012] Preferably, a connecting arm is provided inside the collection shell at the same height as the push block and is fixedly connected to the bottom edge of the sealing plate. The bottom edge of the push block near the sealing plate is set with an inclined surface and the inclined surface abuts against the surface of the connecting arm. Several vertical spring rods are provided between the bottom edge of the sealing plate and the bottom surface inside the collection shell.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, under the suction of the exhaust fan, glass fibers are drawn into the collection shell along the suction pipe. The exhaust fan is stopped, and the door is opened, allowing the glass fibers to fall into the inner box. The door is then closed again, and the sealing plate descends, allowing the glass fibers in the inner box to slide into the chamber and then re-enter the crushing barrel along the channel. From filtration and interception, temporary storage and collection, to extraction, conveying, and return crushing, all steps are completed mechanically, eliminating the need for personnel to contact the fine glass fibers and avoiding the inconvenience of protective operation. The material collection and return process can be carried out simultaneously with the crushing operation of the crushing barrel, without interrupting the main crushing process due to the collection of unqualified materials, thus improving the overall crushing efficiency.

[0014] 2. In this utility model, the electric telescopic rod extends to move the horizontal spring rod to the left, thereby closing the door. After the door is fully closed, the electric telescopic rod continues to extend to elastically retract the horizontal spring rod. During the continuous retraction of the horizontal spring rod, the push block moves towards the connecting arm. The inclined surface of the push block forces the connecting arm to drive the sealing plate to overcome the thrust of the vertical spring rod and descend, thus opening the cavity opening. This allows the glass fiber inside the inner box to enter the cavity when the door is closed, without the need for additional power to drive the sealing plate switch. Attached Figure Description

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] like Figures 1-4 As shown, an alkali-free glass fiber pulverizing device includes a housing 1. A pulverizing barrel 11 is fixedly installed inside the housing 1, and an inclined filter plate 12 is movably installed below the pulverizing barrel 11 inside the housing 1. A pulverizing blade 10 is installed inside the pulverizing barrel 11, with the blade rod at the center of the pulverizing blade 10 penetrating downwards through the filter plate 12 and a lever 14 fixedly installed thereon. A spring rod is provided between the bottom corner of the filter plate 12 and the bottom surface of the housing 1, and a connecting block 15 for sliding connection with the lever 14 is fixedly installed on the bottom surface of the filter plate 12. In actual use, a motor is installed inside the pulverizing barrel 11... The method drives the pulverizer 10 to rotate, which can pulverize the glass fibers put into the pulverizer 11. After pulverization, the glass fibers fall onto the surface of the filter plate 12 for screening, and the glass fibers that are not completely pulverized are intercepted. During the rotation of the pulverizer 10, the bottom connected to the lever 14 will rotate. When rotating, it will push the connecting block 15 to make the filter plate 12 rise against the tension of the spring rod. After the lever 14 and the connecting block 15 are misaligned, the filter plate 12 will fall under the tension of the spring rod. This can realize the reciprocating lifting and lowering of the filter plate 12, and accelerate the screening of glass fibers by shaking. The bottom surface of the inner shell 1 is sloped below the filter plate 12, and a collection box 2 is provided on the outside of the outer shell 1. The opening of the collection box 2 is inserted into the side wall of the outer shell 1 and is distributed at the same height as the lower edge of the slope of the inner bottom surface of the outer shell 1. The crushed and qualified glass fibers fall on the slope of the bottom of the inner shell 1 and slide down into the collection box 2 for collection. A storage tank 8 is fixedly installed at the bottom edge of the outer wall of the outer shell 1. A connecting cover 9 is fixedly installed on the outside of the outer shell 1 at the opening of the storage tank 8. The opening of the connecting cover 9 extends into the outer shell 1 and is at the same height as the bottom edge of the filter plate 12. A sealing strip 17 is slidably installed at the opening of the connecting cover 9. An electric push rod 16 for pushing the sealing strip 17 to slide is fixedly installed on the side of the connecting cover 9 facing away from the outer shell 1. The opening of the storage tank 8 is connected to the middle of the inner bottom surface of the connecting cover 9. Unqualified glass fibers slide down the surface of the filter plate 12 and accumulate at the opening of the connecting cover 9. The sealing strip 17 is moved to the right and the opening of the connecting cover 9 is opened by retracting the electric push rod 16, so that the unqualified glass fibers can slide into the storage tank 8 for collection. A collection shell 6 is fixedly installed on the top edge of the outer surface of the outer shell 1 on the same side as the storage tank 8. An exhaust fan 5 is installed on the collection shell 6. The air inlet of the exhaust fan 5 is connected to the inside of the collection shell 6 and is equipped with filter cotton 19. The filter cotton 19 can prevent glass fibers from being blown out when the exhaust fan 5 draws glass fibers from the storage tank 8. The air outlet of the exhaust fan 5 is located outside the collection shell 6 and is equipped with an air guide hood 4. A blower pipe 3 is fixedly installed at the air outlet of the air guide hood 4 and installed at the mouth of the crushing barrel 11. When the exhaust fan 5 is running, the airflow blown out enters the blower pipe 3 along the air guide hood 4 and is blown into the crushing barrel 11 through the blower pipe 3. By forming a downward airflow at the mouth of the crushing barrel 11, the leakage of glass fibers from the mouth of the crushing barrel 11 during the crushing process can be prevented. A suction pipe 7 is installed on the side of the collection shell 6, which communicates with the exhaust fan 5. The air inlet of the suction pipe 7 extends downward, passes through the side of the storage tank 8, and fits with the center of the bottom surface of the storage tank 8. The center of the bottom of the storage tank 8 is concave and tapered. A vent is provided on the surface of the storage tank 8 near the opening. The tapered shape ensures that the glass fiber accumulates near the suction pipe 7, and under the suction of the exhaust fan 5, the glass fiber is drawn into the collection shell 6 along the suction pipe 7. An inner box 20, which communicates with the air inlet of the exhaust fan 5, is fixedly installed inside the collection shell 6. A door panel 22 is inserted into the inner box 20, and a channel 18 extending into the pulverizing bucket 11 is installed on the bottom edge of the collection box wall. The collecting shell 6 has a chamber 27 that communicates with the channel 18, and the opening of the chamber 27 is located at the bottom edge of the inner box 20. The bottom of the chamber 27 is inclined and a sealing plate 21 for sealing the opening is inserted into the bottom of the chamber 27. When the door panel 22 is closed, the glass fibers adsorbed on the surface of the filter cotton 19 will fall and accumulate on the door panel 22. The exhaust fan 5 is stopped, and then the door panel 22 is opened, so that the glass fibers can fall into the inner box 20. Then the door panel 22 is closed again, and the sealing plate 21 is lowered so that the glass fibers in the inner box 20 slide into the chamber 27 and then re-enter the crushing barrel 11 along the channel 18. No personnel intervention is required during the process.

[0020] A horizontally arranged electric telescopic rod 25 is fixedly installed inside the collection shell 6. A horizontal spring rod 26, coaxially distributed and fixedly connected to the side of the door panel 22, is fixedly installed at the telescopic end of the electric telescopic rod 25. A push block 24 is fixedly installed on the cylinder of the horizontal spring rod 26. A connecting arm 23, fixedly connected to the bottom edge of the sealing plate 21, is located at the same height as the push block 24 inside the collection shell 6. The bottom edge of the push block 24 near the sealing plate 21 is sloped, and the sloped part abuts against the surface of the connecting arm 23. Several vertical spring rods 13 are arranged between the bottom edge of the sealing plate 21 and the bottom surface inside the collection shell 6. Figure 4 The door panel 22 can be opened by retracting the electric telescopic rod 25 and moving the digital display horizontal spring rod 26 to the right, thus sliding the door panel 22 open. During this process, the push block 24 simultaneously drives the connecting arm 23. Alternatively, the door panel 22 can be closed by extending the electric telescopic rod 25 and moving the horizontal spring rod 26 to the left. After the door panel 22 is fully closed, the electric telescopic rod 25 continues to extend, causing the horizontal spring rod 26 to retract elastically. During the continuous retraction of the horizontal spring rod 26, the push block 24 moves towards the connecting arm 23. The inclined surface of the push block 24 forces the connecting arm 23 to drive the sealing plate 21 to overcome the thrust of the vertical spring rod 13 and descend, thereby opening the cavity 27 and allowing the glass fiber inside the inner box 20 to enter the cavity 27 when the door panel 22 is closed.

[0021] The steps for using this utility model are as follows: Screening and retention: The crushed glass fiber falls onto the inclined filter plate 12. Qualified materials pass through the filter plate 12, while unqualified materials that are not completely crushed are retained and slide down the surface of the filter plate 12 to the opening of the connecting cover 9. Temporary storage and collection: The electric push rod 16 retracts, causing the seal 17 to move to the right, opening the cover of the connecting cover 9, and the unqualified material slides into the storage tank 8 for temporary storage; Extraction and conveying: When the exhaust fan 5 is running, the unqualified material in the storage tank 8 is drawn into the collection shell 6 through the dust suction pipe 7. The filter cotton 19 prevents the material from being blown out and the material is adsorbed on the surface of the filter cotton 19. Unloading into the box: When the exhaust fan 5 stops, the material adsorbed on the surface of the filter cotton 19 falls onto the door panel 22 of the inner box 20. The electric telescopic rod 25 retracts, causing the door panel 22 to move to the right and open, and the material falls into the inner box 20. Material reprocessing: After the door panel 22 is closed, the electric telescopic rod 25 continues to extend, causing the horizontal spring rod 26 to retract, which drives the push block 24 to squeeze the connecting arm 23. The sealing plate 21 overcomes the thrust of the vertical spring rod 13 and descends, opening the cavity 27. The material in the inner box 20 slides into the cavity 27 and re-enters the crushing barrel 11 along the channel 18 for secondary crushing.

The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the motor, electric push rod 16, and exhaust fan 5 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
