Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and more specifically to a hydraulic pendulum grinding equipment. Background Technology

[0002] The carbon green anode workshop for aluminum production plays a crucial role in the aluminum electrolysis process. Petroleum coke is one of the main raw materials for green anodes, a byproduct of petroleum refining. The workshop typically has dedicated silos for receiving and storing petroleum coke, which are connected to external transportation systems via belt conveyors or bucket elevators. The petroleum coke requires crushing and grinding to achieve the appropriate particle size. Generally, it is first coarsely crushed using a jaw crusher to break large pieces of petroleum coke into smaller particles. Then, it is further ground using equipment such as a hydraulic pendulum mill to obtain coke powder that meets production requirements.

[0003] Currently, the commonly used hydraulic pendulum mill is also known as the Raymond mill. The Raymond mill operates on the following principle: the material to be crushed is fed into the mill through a feed hopper on the side of the casing, falling between the grinding ring and grinding rollers inside the main unit. The grinding rollers are suspended on a perforated frame of the main unit. Due to the centrifugal force generated during rotation, the grinding rollers swing outwards, pressing tightly against the grinding ring. A shovel is connected to the perforated frame; during rotation, the shovel scoops up the material, forming a material flow that is continuously fed between the grinding rollers and the grinding ring, creating a material layer. As the grinding rollers rotate, they rely on centrifugal force and spring pressure to crush and pulverize the material, achieving a finer finish. For example, there is an R-type pendulum mill with prior art publication number CN213727054U.

[0004] However, in existing hydraulic pendulum mills, environmental factors can cause some of the stored materials to become damp during the grinding process. Because damp materials have a certain degree of stickiness, when they are directly fed into the mill for grinding, they can easily clog the feed hopper and also have an adverse effect on the normal use of the grinding structure. Based on this, this utility model provides a hydraulic pendulum mill with a material drying function. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a hydraulic pendulum grinding device. The pendulum frame acts as a buffer for materials within the feed hopper. Simultaneously, a servo motor drives a rotating rod to reciprocate the connecting plate and the pendulum frame, preventing material blockage on the pendulum frame. Furthermore, multiple heating plates on the pendulum frame generate heat, increasing the temperature inside the feed hopper and thus drying the material. This prevents damp materials from clogging the feed hopper and affecting the grinding effect of the mill, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic pendulum mill, comprising a hydraulic pendulum mill body, a feed inlet at the rear end of the hydraulic pendulum mill body, a feed hopper fixedly mounted at the rear end of the hydraulic pendulum mill body, the feed hopper being connected to the feed inlet, a drying component inside the feed hopper, the drying component including a mounting plate, the mounting plate being detachably connected to the feed hopper and in contact with the outer wall of the hydraulic pendulum mill body, a swing frame at the rear end of the mounting plate, multiple discharge ports at the top of the swing frame, multiple heating plates fixedly embedded inside the swing frame, using heating plates to increase the temperature inside the feed hopper, thereby drying the material, and a drive component for driving the swing frame to swing.

[0007] In a preferred embodiment, a rectangular groove is provided at the rear end of the mounting plate, and the driving assembly includes a rotating rod. The two ends of the rotating rod are rotatably connected to the inner walls of the two sides of the rectangular groove, and a connecting plate is fixedly sleeved on the outer side of the rotating rod. The connecting plate is fixed to the swing frame. The rotating rod drives the connecting plate and the swing frame to rotate, thereby enabling the swing frame to swing and vibrate to prevent materials from clogging the swing frame.

[0008] In a preferred embodiment, a storage slot is provided on one side of the rectangular slot, and a servo motor is fixedly installed inside the storage slot. One end of the output shaft of the servo motor is fixed to one end of the rotating rod. The rotating rod is driven to rotate by the servo motor, eliminating the need for manual operation and saving time and effort in use.

[0009] In a preferred embodiment, rubber pads are fixedly bonded to the inner wall of the feed hopper and the top surface of the swing frame. Since the rubber pads are soft, they can buffer the material below and protect the inner wall at the bottom of the feed hopper. When the rubber pads are worn, they can be replaced simply by tearing them off, making installation and disassembly very convenient.

[0010] In a preferred embodiment, multiple discharge ports are arranged in a linear array on the oscillating frame, and the discharge ports facilitate the direct drop of materials from the oscillating frame.

[0011] In a preferred embodiment, fixing plates are fixedly provided on both sides of the feed hopper, and both fixing plates are detachably connected to the main body of the hydraulic pendulum mill, which facilitates the installation, disassembly, cleaning and replacement of the feed hopper.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This invention uses a swaying frame to buffer materials in the feed hopper. At the same time, a servo motor drives a rotating rod to make the connecting plate and the swaying frame swing back and forth, which can prevent materials from clogging on the swaying frame. In addition, multiple heating plates on the swaying frame generate heat, which can increase the heat inside the feed hopper, thereby drying the materials and preventing damp materials from clogging the feed hopper and affecting the grinding effect of the mill.

[0023] 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.

[0024] Refer to the instruction manual appendix Figure 1-6This utility model provides a hydraulic pendulum mill, including a hydraulic pendulum mill body 1. The rear end of the hydraulic pendulum mill body 1 is provided with a feed inlet 2. The rear end of the hydraulic pendulum mill body 1 is fixedly provided with a feed hopper 3, which is connected to the feed inlet 2. The feed hopper 3 is provided with a drying component 4 inside the feed hopper 3. The drying component 4 includes a mounting plate 401, which is detachably connected to the feed hopper 3 and contacts the outer wall of the hydraulic pendulum mill body 1. The rear end of the mounting plate 401 is provided with a swing frame 402. The top of the swing frame 402 is provided with multiple discharge ports 403, which are arranged in a linear array on the swing frame 402. Multiple heating plates 404 are fixedly embedded inside the swing frame 402. Heating with the heating plates 404 can increase the temperature inside the feed hopper, thereby drying the material.

[0025] The mounting plate 401 is provided with a drive assembly 5 for driving the swing frame 402 to swing. The rear end of the mounting plate 401 is provided with a rectangular groove 6. The drive assembly 5 includes a rotating rod 501. The two ends of the rotating rod 501 are rotatably connected to the inner walls of the two sides of the rectangular groove 6, respectively. A connecting plate 502 is fixedly sleeved on the outer side of the rotating rod 501. The connecting plate 502 is fixed to the swing frame 402. The rotating rod 501 drives the connecting plate 502 and the swing frame 402 to rotate, so that the swing frame 402 can swing and vibrate to prevent material from clogging the swing frame 402.

[0026] Furthermore, a storage slot 503 is provided on one side of the rectangular slot 6. A servo motor 504 is fixedly installed inside the storage slot 503. Specifically, the servo motor 504 is a rotary actuator or a linear actuator, which allows for precise control of angular velocity or linear position, speed and acceleration. One end of the output shaft of the servo motor 504 is fixed to one end of the rotating rod 501. The rotating rod 501 is driven to rotate by the servo motor 504, eliminating the need for manual operation and saving time and effort in use.

[0027] In addition, fixing plates 8 are fixed on both sides of the feed hopper 3. Both fixing plates 8 are detachably connected to the main body 1 of the hydraulic pendulum mill, which facilitates the installation, disassembly, cleaning and replacement of the feed hopper 3.

[0028] During use, the material is conveyed into the feed hopper 3 by the feeding assembly. The material first flows onto the swing frame 402, and then flows from the swing frame 402 into the feed hopper 3. After passing through the feed hopper 3, the material flows into the main body 1 of the hydraulic swing mill for grinding. At the same time, the servo motor 504 drives the rotating rod 501 to drive the connecting plate 502 and the swing frame 402 to swing back and forth. This can prevent the material from clogging on the swing frame 402. In addition, the multiple heating plates 404 on the swing frame 402 generate heat, and the heat is conducted to the rubber pad 7, which can increase the heat inside the feed hopper 3, thereby drying the material and preventing damp material from entering the mill and affecting the grinding effect.

[0029] Refer to the instruction manual appendix Figure 4 Rubber pads 7 are fixedly bonded to the inner wall of the feed hopper 3 and the top surface of the swing frame 402. With the rubber pads 7 on the inner wall of the feed hopper 3, when the material slides off the swing frame 402, the soft material of the rubber pads 7 can buffer the material and also protect the bottom inner wall of the feed hopper 3. When the rubber pads 7 are worn, they can be replaced simply by tearing them off, making installation and disassembly very convenient.
