Description

Technical Field

[0001] This utility model relates to the field of negative pressure pulverizer technology, and in particular to a mechanical pulverizer with a dust negative pressure collection mechanism. Background Technology

[0002] Mechanical pulverizers are widely used in chemical, metallurgical, and building materials industries, playing a crucial role, especially in the processing of lithium battery raw materials. Lithium battery raw materials, such as positive and negative electrode materials, need to be pulverized to achieve the required particle size for subsequent processing. However, the pulverization process generates a large amount of dust, which not only pollutes the working environment but may also harm the health of operators. Furthermore, dust spillage leads to raw material waste and increases production costs.

[0003] Existing mechanical crushers have some shortcomings in terms of dust collection and discharge efficiency:

[0004] First, traditional crushers lack efficient dust collection devices, resulting in serious dust overflow and failing to meet environmental protection requirements. Second, when the crushed raw materials are screened and discharged, they tend to accumulate at the discharge port, resulting in slow discharge speed and affecting production efficiency. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a mechanical pulverizer with a dust negative pressure collection mechanism, which overcomes the shortcomings of the prior art and effectively solves the problems of dust overflow and slow feeding speed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mechanical pulverizer with a dust negative pressure collection mechanism includes a pulverizing cylinder. A feed hopper is welded to the center of the outer wall of the top of the pulverizing cylinder, and a dust suction pipe is welded to the inner wall of one side of the feed hopper. A cyclone separator is fixedly connected to the outer wall of one end of the dust suction pipe through a flange. An exhaust pipe is fixedly connected to the outer wall of the top of the cyclone separator. A blower is fixedly connected to the outer wall of one end of the exhaust pipe, and a dust discharge port is provided on the outer wall of the bottom of the cyclone separator.

[0008] A discharge hopper is welded to the bottom outer wall of the crushing cylinder, and a servo motor is fixedly connected to the bottom outer wall of the discharge hopper by screws. The output shaft of the servo motor is fixedly connected to a column by a coupling, and a discharge auxiliary plate is welded to the outer wall of the column.

[0009] Preferably, the discharge auxiliary plate is disposed inside the discharge hopper, and the discharge auxiliary plate is closely attached to the bottom inner wall of the discharge hopper.

[0010] Preferably, a crushing blade is fixedly connected to the top outer wall of the column by screws, and a screen is welded between the crushing cylinder and the feed hopper, with the crushing blade closely attached to the top outer wall of the screen.

[0011] Preferably, a discharge pipe is welded to the bottom outer wall of the discharge hopper, and a collection frame is provided at the bottom of the outer wall of one end of the discharge pipe, with the powder discharge port located directly above the collection frame.

[0012] Preferably, the top outer wall of the crushing cylinder has a feed inlet located at the bottom of the feed hopper.

[0013] Preferably, a support plate is welded to one side of the outer wall of the crushing cylinder, and the cyclone separator is installed on the inner wall of the support plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The mechanical pulverizer with a dust negative pressure collection mechanism designed in this paper achieves efficient dust collection through the synergistic action of the suction pipe, cyclone separator and blower. The suction pipe can suck the dust generated during the pulverization process into the cyclone separator. The dust will be separated from the airflow by centrifugal force in the cyclone separator and finally discharged from the discharge port and collected in a concentrated manner. This effectively solves the problem of dust overflow, improves the working environment, and also reduces raw material waste, which meets environmental protection requirements.

[0016] 2. The mechanical pulverizer with a dust negative pressure collection mechanism designed in this paper, through the cooperation of the discharge auxiliary plate and the pulverizing blade driven by the servo motor, helps to improve the discharge efficiency. The discharge auxiliary plate rotates close to the inner wall of the discharge hopper to prevent raw material accumulation, and the pulverizing blade rotates close to the screen to ensure that the raw material passes through the screen quickly and enters the discharge pipe. This solves the problem of slow material discharge in traditional pulverizers and improves production efficiency. It is especially suitable for the continuous processing of lithium battery raw materials. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 Example 1: A mechanical pulverizer with a dust negative pressure collection mechanism includes a pulverizing cylinder 1. A feed hopper 2 is welded to the center of the top outer wall of the pulverizing cylinder 1, and a dust suction pipe 3 is welded to the inner wall of one side of the feed hopper 2. A cyclone separator 4 is fixedly connected to the outer wall of one end of the dust suction pipe 3 through a flange. An exhaust pipe 5 is fixedly connected to the top outer wall of the cyclone separator 4. A blower 6 is fixedly connected to the outer wall of one end of the exhaust pipe 5. A dust discharge port 7 is provided on the bottom outer wall of the cyclone separator 4. A feed inlet 16 is opened on the top outer wall of the pulverizing cylinder 1 at the bottom of the feed hopper 2.

[0024] A feed hopper 2 is welded to the top of the crushing cylinder 1. A dust suction pipe 3 is welded to the inner wall of one side of the feed hopper 2 for sucking up dust. A feed inlet 16 is provided at the bottom of the feed hopper 2, through which raw materials enter the crushing cylinder 1. The dust suction pipe 3 is connected to a cyclone separator 4 via a flange to ensure the sealing of dust collection. An exhaust pipe 5 is connected to the top of the cyclone separator 4, and a blower 6 is installed at the end of the exhaust pipe 5. The blower 6 generates negative pressure to suck dust into the cyclone separator 4. A dust discharge port 7 is provided at the bottom of the cyclone separator 4, where dust is collected and discharged to the collection frame 15.

[0025] In this embodiment, efficient dust collection is achieved through the synergistic effect of the dust suction pipe 3, the cyclone separator 4, and the blower 6. The dust suction pipe 3 can suck the dust generated during the crushing process into the cyclone separator 4. The dust will be separated from the airflow by centrifugal force in the cyclone separator 4 and finally discharged from the dust discharge port 7 and collected in a concentrated manner. This effectively solves the problem of dust overflow, improves the working environment, and also reduces raw material waste, which meets environmental protection requirements.

[0026] In embodiment 2, a discharge hopper 8 is welded to the bottom outer wall of the crushing cylinder 1, and a servo motor 9 is fixedly connected to the bottom outer wall of the discharge hopper 8 by screws. The output shaft of the servo motor 9 is fixedly connected to a column 10 by a coupling, and a discharge auxiliary plate 12 is welded to the outer wall of the column 10. The discharge auxiliary plate 12 is disposed inside the discharge hopper 8 and is tightly attached to the bottom inner wall of the discharge hopper 8. A crushing blade 11 is fixedly connected to the top outer wall of the column 10 by screws, and a screen 13 is welded between the crushing cylinder 1 and the feed hopper 2. The crushing blade 11 is tightly attached to the top outer wall of the screen 13.

[0027] The servo motor 9 drives the column 10 to rotate via a coupling. The column 10 is welded with a crushing blade 11 and a discharge auxiliary plate 12. The crushing blade 11 rotates close to the screen 13 to crush the raw material to the required fineness. The screen 13 is welded between the crushing cylinder 1 and the feed hopper 2 to ensure that the raw material passes through the screen 13 and enters the discharge hopper 8 after crushing. Raw materials that do not meet the standards continue to be crushed to improve crushing efficiency. The discharge auxiliary plate 12 rotates close to the inner wall of the discharge hopper 8 to prevent raw material accumulation.

[0028] In this embodiment, the cooperation between the discharge auxiliary plate 12 driven by the servo motor 9 and the crushing blade 11 helps to improve the discharge efficiency. The discharge auxiliary plate 12 rotates close to the inner wall of the discharge hopper 8 to prevent the raw materials from accumulating. The crushing blade 11 rotates close to the screen 13 to ensure that the raw materials pass through the screen 13 quickly and enter the discharge pipe 14. This solves the problem of slow material discharge in traditional crushers and improves production efficiency, especially suitable for continuous processing of lithium battery raw materials.

[0029] The bottom outer wall of the discharge hopper 8 is welded with a discharge pipe 14, and a collection frame 15 is provided at the bottom of the outer wall of one end of the discharge pipe 14, with the powder discharge port 7 located directly above the collection frame 15.

[0030] The discharge pipe 14 conveys the crushed raw materials to the collection frame 15 to complete the discharge.

[0031] A support plate 17 is welded to one side of the outer wall of the crushing cylinder 1, and the cyclone separator 4 is installed on the inner wall of the support plate 17.

[0032] Working principle:

[0033] Feeding and crushing: The raw material enters the crushing cylinder 1 from the feed hopper 2 through the feed port 16. The servo motor 9 drives the column 10 to rotate, which in turn drives the crushing blade 11 to crush the raw material.

[0034] Dust collection: The dust generated during the crushing process is sucked into the cyclone separator 4 by the dust suction pipe 3. Inside the cyclone separator 4, the dust is separated from the airflow due to centrifugal force, the clean air is discharged through the exhaust pipe 5, and the dust falls into the collection frame 15 from the dust discharge port 7.

[0035] Discharge: The crushed raw material enters the discharge hopper 8 through the screen 13. The discharge auxiliary plate 12 rotates and pushes the raw material into the discharge pipe 14, and finally falls into the collection frame 15.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
