Description

Technical Field

[0001] This utility model relates to the field of pulverizer technology, specifically a pulverizer with a high-efficiency screening structure. Background Technology

[0002] Crushers are generally used to break large pieces of material into smaller pieces, making it easier for subsequent transportation or processing. However, since the pieces are of different sizes, screens are often added for screening to facilitate subsequent classification.

[0003] Authorization Announcement No. CN219748620U: A pulverizer with a screening structure, comprising: a machine body, a pulverizing roller rotatably connected to the inner side of the machine body, a feed hopper, a first discharge port, and a second discharge port provided on the machine body, and guide rods symmetrically slidably arranged on the inner side of the machine body, the upper end of the guide rods being fixedly connected to an integral plate.

[0004] When a pulverizer is pulverizing, it inevitably produces fine fragments. The screens installed are too large to filter these fine fragments. Therefore, we propose a pulverizer with a high-efficiency screening structure. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a crusher with a high-efficiency screening structure, which cleans up fine fragments and powders during the tumbling process of the crushed material, improves the screening quality, and can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pulverizer with a high-efficiency screening structure, comprising a shell (1), a pulverizing mechanism installed at the upper end of the shell (1), the pulverizing mechanism being used to pulverize materials, a screen one (4) obliquely fixedly connected to the upper inner side of the shell (1), a screen two (7) obliquely fixedly connected to the lower inner side of the shell (1), the left ends of the screen two (7) and the screen one (4) being far apart, and the right ends of the screen two (7) and the screen one (4) being close together, a guide plate (6) fixedly connected inside the shell (1) between the screen one (4) and the screen two (7), the guide plate (6) being parallel to the screen one (4), and the right end of the guide plate (6) being shorter than the screen one (4). 4) The right side surface of the housing (1) is connected to the discharge pipe 1 (5) at the right end of the screen 1 (4), the left side surface of the housing (1) is connected to the discharge pipe 2 (8) at the left end of the screen 2 (7), and the rear side surface of the housing (1) is connected to the exhaust pipe (12) at the right side of the cam (11). The exhaust pipe (12) is rotatably connected to the rotating rod inside, the front end of the rotating rod is fixedly connected to the exhaust fan (16), and the rear end of the rotating rod extends through the round hole opened on the exhaust pipe (12) to the rear side of the exhaust pipe (12) and is fixedly connected to the driven wheel (15). The driven wheel (15) is connected to the rotating wheel (13) through the transmission belt (14), and the rotating wheel (13) is connected to the vibration mechanism.

[0007] Screen 1 (4) and screen 2 (7) are designed to screen and separate the crushed material, thereby improving the quality of subsequent fragments and preventing larger fragments from flowing out. A guide plate (6) is designed to guide the falling fragments, thereby extending the fragment screening time and improving the screening quality. At the same time, the fragments are tumbled, making it easier for small fragments to be sucked out. An exhaust fan (16) is designed to suck out the small fragments generated during crushing, thereby improving the screening quality. When the control device is working, the material is first initially crushed by the crushing mechanism. The crushed material falls onto screen one (4) for preliminary screening. The fragments that meet the specifications pass through screen one (4) and fall onto the guide plate (6). After being guided by the guide plate (6), they fall to the right end of screen two (7) and then gradually roll to the left. During the process, they are screened again through screen two (7). Those that meet the specifications continue to fall. At the same time, the vibration mechanism drives the rotating wheel (13) to rotate, which in turn drives the driven wheel (15) to rotate through the transmission belt (14), which in turn drives the rotating rod to rotate, which in turn drives the exhaust fan (16) to rotate to extract the small fragments.

[0008] Furthermore, the crushing mechanism includes crushing rollers (2). Crushing rollers (2) are longitudinally arranged on the left and right sides of the upper port of the housing (1). The front and rear ends of the two crushing rollers (2) are rotatably connected to the corresponding positions of the front and rear inner walls of the housing (1) through bearings. The upper part of the front surface of the housing (1) is fixedly connected to a motor (3). The input end of the motor (3) is electrically connected to the output end of an external power supply through an external control switch group. The output shaft of the motor (3) extends through the round hole opened at the corresponding position on the housing (1) to the inside of the housing (1) and is fixedly connected to the front end of the crushing roller (2) on the left side. The rear ends of the two crushing rollers (2) extend through the round hole opened on the rear surface of the housing (1) to the rear part of the housing (1) and are fixedly connected to gears respectively. The two gears mesh with each other.

[0009] When the crushing mechanism is in operation, the motor (3) is controlled to rotate by the external control switch group, which in turn drives the left crushing roller (2) to rotate, which in turn drives the corresponding gear to rotate, which in turn drives the right crushing roller (2) to rotate, thereby performing the crushing work.

[0010] Furthermore, the vibration mechanism includes a round rod (10). The round rod (10) is respectively installed inside the housing (1) at the lower side of screen one (4) and screen two (7). The front and rear ends of the two round rods (10) are rotatably connected to the corresponding positions on the housing (1) through bearings. The front and rear parts of the two round rods (10) are respectively fitted with cams (11). The two cams (11) are respectively in contact with the lower surface of the corresponding screen one (4) and screen two (7). The rear end of the upper round rod (10) extends through the round hole opened on the housing (1) to the rear part of the housing (1) and is fixedly connected to the rotating wheel (13).

[0011] The cam (11) is designed to strike the first screen (4) and the second screen (7), thereby causing the first screen (4) and the second screen (7) to vibrate, thus improving the efficiency of the screening work. When the striking work is carried out, the two round rods (10) are rotated, which in turn drives the two cams (11) to rotate, thereby striking the first screen (4) and the second screen (7), thus causing the first screen (4) and the second screen (7) to vibrate.

[0012] Furthermore, the vibration mechanism also includes a second motor (9). The upper and lower parts of the front surface of the housing (1) are fixedly connected to the second motor (9). The output shafts of the two second motors (9) extend through the round holes opened on the housing (1) to the interior of the housing (1) and are fixedly connected to the front end of the corresponding round rod (10). The input end of the second motor (9) is electrically connected to the output end of the external power supply through an external control switch group.

[0013] The motor 2 (9) is controlled by an external control switch group, thereby driving the corresponding round rod (10) to rotate.

[0014] Furthermore, the crusher also includes a transfer box (17), which is provided on the lower side of the housing (1). The upper end of the transfer box (17) is slidably connected to a sliding groove opened at a corresponding position on the lower surface of the housing (1) by a fixedly connected slide bar.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Please see Figure 1-4 This embodiment provides a technical solution: a pulverizer with a high-efficiency screening structure, including a shell 1. A pulverizing mechanism is installed at the upper end of the shell 1 for pulverizing materials. A screen 4 is obliquely fixedly connected to the upper inner side of the shell 1, and a screen 7 is obliquely fixedly connected to the lower inner side of the shell 1. The left ends of screen 7 and screen 4 are far apart, while the right ends of screen 7 and screen 4 are close together. A guide plate 6 is fixedly connected inside the shell 1 between screen 4 and screen 7. The guide plate 6 is parallel to screen 4, and the right end of the guide plate 6 is shorter than screen 4. The right side surface of body 1 is connected to the right end of screen 4 and the discharge pipe 5. The left side surface of body 1 is connected to the left end of screen 7 and the discharge pipe 8. The rear side surface of body 1 is connected to the right side of cam 11 and the exhaust pipe 12. The exhaust pipe 12 is rotatably connected to a rotating rod. The front end of the rotating rod is fixedly connected to an exhaust fan 16. The rear end of the rotating rod extends through a round hole in the exhaust pipe 12 to the rear side of the exhaust pipe 12 and is fixedly connected to a driven wheel 15. The driven wheel 15 is connected to the rotating wheel 13 via a transmission belt 14. The rotating wheel 13 is connected to the vibration mechanism.

[0027] Screens 4 and 7 are designed to screen and separate the crushed material, thereby improving the quality of subsequent fragments and preventing larger fragments from flowing out. A guide plate 6 is designed to guide the falling fragments, thereby extending the fragment screening time and improving screening quality. It also makes the fragments tumble, making it easier for small fragments to be sucked out. An exhaust fan 16 is designed to suck out small fragments generated during crushing, thereby improving screening quality. When the control device is working, the material is first initially crushed by the crushing mechanism. The crushed material falls onto screen 4 for initial screening. Fragments that meet the specifications pass through screen 4 and fall onto guide plate 6. After being guided by guide plate 6, they fall to the right end of screen 7 and then gradually roll to the left. During this process, they are screened again by screen 7. Those that meet the specifications continue to fall. At the same time, the vibration mechanism drives the rotating wheel 13 to rotate, which in turn drives the driven wheel 15 to rotate through the transmission belt 14, which in turn drives the rotating rod to rotate, which in turn drives the exhaust fan 16 to rotate to suck out small fragments.

[0028] The crushing mechanism includes crushing rollers 2. Crushing rollers 2 are longitudinally arranged on the left and right sides of the upper port of the housing 1. The front and rear ends of the two crushing rollers 2 are rotatably connected to the corresponding positions of the front and rear inner walls of the housing 1 through bearings. A motor 3 is fixedly connected to the upper part of the front surface of the housing 1. The input end of the motor 3 is electrically connected to the output end of an external power supply through an external control switch group. The output shaft of the motor 3 extends through a circular hole opened at a corresponding position on the housing 1 to the inside of the housing 1 and is fixedly connected to the front end of the left crushing roller 2. The rear ends of the two crushing rollers 2 extend through a circular hole opened through the rear surface of the housing 1 to the rear of the housing 1 and are fixedly connected to gears respectively. The two gears mesh with each other.

[0029] When the crushing mechanism is in operation, the motor 3 is controlled to rotate by the external control switch group, which in turn drives the left crushing roller 2 to rotate, which in turn drives the corresponding gear to rotate, which in turn drives the right crushing roller 2 to rotate, thereby performing the crushing work.

[0030] The vibration mechanism includes round rods 10. Round rods 10 are respectively installed inside the housing 1 at the lower side of screen 4 and screen 7. The front and rear ends of the two round rods 10 are rotatably connected to the corresponding positions on the housing 1 through bearings. Cams 11 are respectively sleeved on the front and rear parts of the two round rods 10. The two cams 11 contact the lower surface of the corresponding screen 4 and screen 7. The rear end of the upper round rod 10 extends through the round hole opened on the housing 1 to the rear part of the housing 1 and is fixedly connected to the rotating wheel 13.

[0031] The cam 11 is designed to strike the screen 4 and the screen 7, thereby causing the screen 4 and the screen 7 to vibrate, thus improving the efficiency of the screening work. When striking, it drives the two round rods 10 to rotate, which in turn drives the two cams 11 to rotate, thereby striking the screen 4 and the screen 7, causing the screen 4 and the screen 7 to vibrate.

[0032] The vibration mechanism also includes motor 2 9. Motor 2 9 is fixedly connected to the upper and lower parts of the front surface of housing 1 respectively. The output shafts of the two motors 2 9 extend through the round holes opened on housing 1 to the inside of housing 1 and are fixedly connected to the front end of the corresponding round rod 10. The input end of motor 2 9 is electrically connected to the output end of external power supply through an external control switch group.

[0033] The motor 29 is controlled by an external control switch group, which in turn drives the corresponding round rod 10 to rotate.

[0034] The crusher also includes a transfer box 17. The transfer box 17 is provided on the lower side of the housing 1. The upper end of the transfer box 17 is slidably connected to the slide groove opened at the corresponding position on the lower surface of the housing 1 through a fixedly connected slide bar.

[0035] The transfer box 17 is designed to collect and transfer qualified falling fragments.

[0036] The working principle of the pulverizer with a high-efficiency screening structure provided by this utility model is as follows:

[0037] When the crushing mechanism is in operation, the external control switch group controls the motor 3 to rotate, which in turn drives the left crushing roller 2 to rotate, which in turn drives the corresponding gear to rotate, which in turn drives the right crushing roller 2 to rotate, thus performing the crushing work. The crushed pieces fall onto the screen 4 for preliminary screening. Pieces that meet the specifications pass through the screen 4 and fall onto the guide plate 6. After being guided by the guide plate 6, they fall to the right end of the screen 7 and then gradually roll to the left. Along the way, they are screened again by the screen 7. Those that meet the specifications continue to fall. At the same time, the external control switch group controls the motor 9 to operate, which drives the corresponding round rod 10 to rotate, which in turn drives the two cams 11 to rotate, thus striking the screens 4 and 7, causing them to vibrate. The upper round rod 10 drives the rotating wheel 13 to rotate, which in turn drives the driven wheel 15 to rotate through the transmission belt 14, which in turn drives the rotating rod to rotate, which in turn drives the exhaust fan 16 to rotate to extract the fine pieces.

[0038] It is worth noting that the method of controlling the operation of motor 3 and motor 9 by means of an external control switch group disclosed in the above embodiments adopts a method commonly used in the prior art.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
