Description

Technical Field

[0001] This utility model relates to the technical field of glass crushing and screening machines, specifically to a multi-stage integrated glass crushing and screening machine. Background Technology

[0002] With the rapid development of the resource recycling industry, the demand for recycling and processing of glass, as a material with extremely high recyclability, is increasing day by day. Whether it is waste building glass, automotive glass, or daily-use glass products, the recycling process requires core steps such as crushing and screening to obtain glass fragments with uniform particle size and low impurity content, providing qualified raw materials for subsequent reprocessing (such as the preparation of glass fiber, microcrystalline glass, or remelting to make bottles).

[0003] When performing glass crushing and screening operations, a corresponding multi-stage crushing and screening integrated machine is usually used. This type of multi-stage crushing and screening integrated machine has a crushing roller on its own, which can perform crushing operations, and then through its built-in multi-stage screen, it can achieve the effect of multi-stage screening.

[0004] However, in practical use, this type of multi-stage crushing and screening integrated machine still has some shortcomings. For example, when using crushing rollers for crushing, since the distance between two adjacent crushing rollers is constant, when encountering large pieces of glass, or when the falling angle of large pieces of glass is not aligned with the crushing rollers, the crushing rollers cannot act properly on the glass, affecting the crushing effect. In view of this, we propose a multi-stage crushing and screening integrated glass machine. Utility Model Content

[0005] The purpose of this invention is to provide a multi-stage glass crushing and screening machine to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A multi-stage glass crushing and screening integrated machine includes a screening box. A feed pipe is fixedly installed on the top of the screening box, and a feed hopper is fixedly installed at the top end of the feed pipe. A support frame is fixedly installed on the top surface of the screening box, and a hydraulic cylinder is fixedly installed on the top plate of the support frame. A crushing hammer is detachably installed at the end of the telescopic shaft of the hydraulic cylinder, and the crushing hammer is located at the feed hopper. The top box of the screening box is also provided with a crushing assembly for crushing the discharge end of the feed pipe. The crushing assembly includes two symmetrical rotating shafts that are rotatably connected to the front and rear side plates of the screening box. Crushing rollers are fixedly installed on the rotating shafts, and the two crushing rollers are driven by gears and a drive motor.

[0007] Preferably, the gear is mounted on the end of the corresponding rotating shaft, the gear is located outside the screening box, and the two gears mesh with each other.

[0008] Preferably, one end of the rotating shaft is mounted on the output shaft of the drive motor, and the drive motor is fixedly mounted on the outer side of the screening box.

[0009] Preferably, a discharge pipe is fixedly installed at the bottom of the screening box, and two symmetrical vibrating motors are fixedly installed at the bottom of the screening box. This feature facilitates the discharge of falling glass from the discharge pipe, while the vibration generated by the vibrating motor improves the screening effect.

[0010] Preferably, multiple perforated screen plates are fixedly installed on the inner wall of the screening box from top to bottom, and the aperture of the through holes in the multiple perforated screen plates decreases sequentially from top to bottom; This setting enables multi-stage screening operations.

[0011] Preferably, a discharge hopper that extends out of the screening box is fixedly installed at the end of the mesh screen plate, and a conveyor belt for conveying the screened glass is provided at the discharge hopper. This setting allows the glass on the corresponding mesh screen plate to fall down the unloading hopper to the conveyor belt for conveying.

[0012] Preferably, multiple cleaning holes are provided on both the left and right side plates of the screening box, and a cover plate is detachably installed on the cleaning hole. The cover plate is located below the corresponding mesh screen plate. This setting allows the cover to be opened for cleaning when necessary.

[0013] Preferably, multiple side plates are fixedly installed at the top and bottom positions of the left and right side panels of the screening box, and multiple support columns are provided on the left and right sides of the screening box. The side plates are fitted onto the support columns, and two mutually symmetrical support plates are fixedly installed on the support columns. The support plates are located below the corresponding side plates. A spring is fixedly installed between the support plates and the side plates. The spring is wound around the support column. A fixed base is fixedly installed at the bottom end of the support column. The fixed base is fixedly installed on an external base. This setting supports the screening box, while the springs improve the vibration screening effect. Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of hydraulic cylinder and crushing hammer, and the installation position of the feeding hopper, realizes the pre-crushing treatment of large pieces of glass or glass whose falling angle is not aligned with the crushing roller, avoiding the situation that the crushing roller spacing is constant and cannot effectively act on the glass, thereby improving the overall glass crushing effect and ensuring the stable operation of the crushing operation.

[0014] 2. This utility model achieves secondary precise crushing and multi-stage stratified screening of glass through the intermeshing gears and the crushing roller driven by the drive motor, as well as multiple mesh screen plates with progressively smaller apertures from top to bottom in the screening box. At the same time, the vibration motor and the springs in the support structure enhance the vibration effect of the screening box, thereby improving the uniformity of glass fragment particle size and meeting the particle size requirements of different recycling processes.

[0015] 3. This utility model, through the unloading hopper and conveyor belt extending out of the screening box, as well as the cleaning holes and detachable cover on the side plate of the screening box, realizes the convenient conveying of glass fragments of different particle sizes and the timely cleaning of the inside of the screening box, avoiding material accumulation that affects the operation of the equipment.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Please see Figures 1-3 This utility model provides a technical solution: a multi-stage glass crushing and screening integrated machine, including a screening box 1, a feed pipe 4 fixedly installed on the top of the screening box 1, a feed hopper 40 fixedly installed at the top of the feed pipe 4, a support frame 6 fixedly installed on the top surface of the screening box 1, a hydraulic cylinder 60 fixedly installed on the top plate of the support frame 6, and a crushing hammer 61 detachably installed at the end of the telescopic shaft of the hydraulic cylinder 60. The crushing hammer 61 is located at the feed hopper 40, so that the hydraulic cylinder 60 drives the crushing hammer 61 to pre-crush large pieces of glass or glass with poor falling angle at the feed hopper 40, avoiding the problem that traditional crushing rollers cannot effectively crush such glass due to constant spacing, and laying a good foundation for the operation of the subsequent crushing component 5.

[0018] In this embodiment, the top box of the screening box 1 is also equipped with a crushing component 5 for crushing the discharge end of the feed pipe 4. The crushing component 5 includes two symmetrical rotating shafts 50 that are rotatably connected to the front and rear side plates of the screening box 1. Crushing rollers 51 are fixedly installed on the rotating shafts 50. The two crushing rollers 51 are driven by gears 52 and a drive motor 53. The gears 52 are installed at the ends of the corresponding rotating shafts 50 and are located outside the screening box 1. The two gears 52 mesh with each other. The end of one of the rotating shafts 50 is installed on the output shaft of the drive motor 53. The drive motor 53 is fixedly installed on the outer side of the screening box 1, so that the two crushing rollers 51 can rotate synchronously in opposite directions to perform secondary precise crushing of the glass at the discharge end of the feed pipe 4, thereby improving the uniformity of glass crushing and meeting the subsequent screening requirements.

[0019] like Figure 1 As shown, a discharge pipe 10 is fixedly installed at the bottom of the screening box 1, and two symmetrical vibrating motors 11 are fixedly installed at the bottom of the screening box 1. This allows the glass fragments that fall vertically after crushing and screening to be smoothly discharged from the discharge pipe 10. At the same time, the vibration generated by the vibrating motors 11 can accelerate the falling and screening of the glass fragments in the screening box 1, effectively improving the screening efficiency and reducing material accumulation.

[0020] like Figure 1As shown, multiple perforated screen plates 12 are fixedly installed on the inner wall of the screening box 1 from top to bottom. The aperture of the through holes in the multiple perforated screen plates 12 decreases sequentially from top to bottom, so that the glass fragments can be screened in multiple layers during the falling process. The perforated screen plates 12 with different apertures can separate glass fragments of different particle sizes, which can meet the differentiated needs of subsequent recycling processing for glass fragments of different particle sizes and solve the problem of poor accuracy of traditional single-stage screening.

[0021] like Figure 1 As shown, a discharge hopper 13 is fixedly installed at the end of the mesh screen plate 12, extending out of the screening box 1. A conveyor belt 3 is provided at the discharge hopper 13 to transport the screened glass, so that the glass fragments screened on each mesh screen plate 12 can fall down the discharge hopper 13 onto the conveyor belt 3, and be quickly transported to the designated position by the conveyor belt 3. This avoids the trouble of manual handling, reduces labor costs, and improves material transfer efficiency. The conveyor belt 3 is driven by an external drive shaft and a motor. The working principle of the conveyor belt 3 is the existing conventional technology, which will not be described in detail here.

[0022] like Figure 2 As shown, multiple cleaning holes 14 are provided on both the left and right side plates of the screening box 1. A cover plate 141 is detachably installed on the cleaning hole 14. The cover plate 141 is located below the corresponding mesh screen plate 12, so that after the equipment has been used for a period of time, the operator can open the cover plate 141 and clean the impurities or residual materials accumulated inside the screening box 1 and below the mesh screen plate 12 through the cleaning hole 14 to ensure the cleanliness of the equipment and maintain the screening effect. The cover plate 141 can be detachably installed on the side of the screening box 1 by multiple fastening screws.

[0023] like Figure 1 As shown, multiple side plates 15 are fixedly installed at the top and bottom of the left and right side panels of the screening box 1. Multiple support columns 2 are provided on both the left and right sides of the screening box 1. The side plates 15 are fitted onto the support columns 2. Two symmetrical support discs 20 are fixedly installed on the support columns 2. The support discs 20 are located below the corresponding side plates 15. A spring 21 is fixedly installed between the support discs 20 and the side plates 15. The spring 21 is wound around the support column 2. A fixed base 22 is fixedly installed at the bottom of the support column 2. The fixed base 22 is fixedly installed on the external base, so that the support column 2 provides stable support for the screening box 1. At the same time, the spring 21 can enhance the vibration effect of the screening box 1 under the action of the vibrating motor 11, further improving the screening efficiency. The fixed base 22 ensures the overall stability of the equipment during operation.

[0024] Finally, it should be noted that the hydraulic cylinder 60, drive motor 53, vibration motor 11, corresponding hydraulic control system, circuit control system, and external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adapted controllers and power supplies, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0025] When using the glass crushing and screening integrated machine of this utility model, the waste glass to be processed is first put into the feed hopper 40 at the top of the feed pipe 4 at the top of the screening box 1. The hydraulic cylinder 60 is started, which drives the crushing hammer 61 to move up and down in the feed hopper 40 to pre-crush large pieces of glass or glass with poor falling angle. The pre-crushed glass falls into the top box of the screening box 1 through the feed pipe 4. At this time, the drive motor 53 on the outer side of the screening box 1 is started, which drives the connected rotating shaft 50 to rotate. Through two meshing gears 52, the other rotating shaft 50 is rotated synchronously in the opposite direction, so that the two crushing rollers 51 can crush the glass for a second time with precision. The broken glass fragments fall onto the mesh screen plate 12 inside the screening box 1. The vibration motor 11 at the bottom is started, and the vibration effect is enhanced by the spring 21 on the support column 2. The glass fragments are screened in multiple stages on the mesh screen plate 12 with the aperture decreasing from top to bottom. Fragments of different sizes fall onto the conveyor belt 3 through the discharge hopper 13 at the end of the corresponding mesh screen plate 12. The conveyor belt 3 transports them to the designated position. The finest fragments are discharged through the bottom discharge pipe 10. After the equipment has been used for a period of time, the cover plate 141 on the cleaning hole 14 on the side plate of the screening box 1 can be opened to clean the internal residual impurities.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
