Description

A raw material roller press with stable feeding capability Technical Field

[0001] This utility model relates to the field of cement production equipment technology, specifically to a raw material roller press that can stably feed raw materials. Background Technology

[0002] Roller press, also known as extrusion mill, roller mill, or double roller mill, is a new type of energy-saving cement grinding equipment. It can replace the high-energy-consumption and low-efficiency ball mill pre-grinding system, and reduce steel consumption and noise. It is suitable for new plant construction and can also be used for technical transformation of old plants, increasing the output of ball mill systems by 30-50%. After extrusion, the raw material cake contains 20-35% fine particles of 0.08mm and 65-85% particles smaller than 2mm. The internal structure of the small particles is filled with many tiny cracks due to extrusion, which greatly improves their grindability. The roller surface is hot-stacked, making the wear-resistant layer easier to maintain.

[0003] A raw material roller press according to announcement number CN217549891U includes: a housing, connecting rods, and pressing blocks. Bearings are embedded on both sides of the front and rear ends of the housing. Two sets of bearings are rotatably mounted on movable rods. A driven roller is mounted on one movable rod inside the housing, and a driving roller is mounted on the movable rod on the other movable rod inside the housing. Fixed blocks are welded in a circular array on both the driving and driven rollers. Screws are welded to the top of each fixed block. A screw hole is formed at the bottom of the pressing block. Supports are welded to the four corners of the bottom of the housing. Movable grooves are formed at the bottom of each of the four support columns, and springs are installed inside each of the four movable grooves. This invention has the advantages of facilitating the replacement of severely worn pressing blocks, ensuring the quality of crushed raw material, reducing equipment vibration, and avoiding resonance.

[0004] Regarding the aforementioned solutions, the raw material is rolled using the cooperation of the active and driven rollers, and the rolled raw material is discharged through the discharge pipe. However, since no stabilizing mechanism is set up in this process, the raw material is easily subjected to large impacts during discharge, which can easily cause fluctuations in the discharge of raw material, making it difficult to stabilize the composition of raw material and easily causing dust. This makes the use of the raw material roller press quite inconvenient. Summary of the Invention

[0005] Based on this, the purpose of this utility model is to provide a raw material roller press that can stably feed raw materials, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material roller press capable of stable feeding, comprising a roller press body, a feed hopper, and a discharge hopper. The feed hopper is provided at the top of the roller press body, and the discharge hopper is provided at the bottom of the roller press body. A roller pressing mechanism is provided through the inner side of the roller press body below the feed hopper. The roller pressing mechanism includes a pressure roller, a drive motor, and a gear set A. The pressure roller is rotatably connected to the inner side of the roller press body via bearings. The bottom end of the inner side of the roller press body is configured as an inclined surface structure.

[0007] A dispersion plate is provided on the inner side of the roller press body below the pressure roller. A stabilizing mechanism is provided through the inner side of the roller press body below the dispersion plate. The stabilizing mechanism includes a rotary motor, a gear set B, a pulley set, a support shaft, a stabilizing plate, and a sleeve. The support shaft is rotatably connected to the inside of the roller press body through bearings. The sleeve is fitted on the outer surface of the support shaft. The stabilizing plate is set at equal angles on the outer surface of the sleeve.

[0008] Preferably, the dispersing plate is configured with an inverted "V" shape, and both ends of the dispersing plate are welded to the main body of the roller press.

[0009] Preferably, the front end of the roller press body is provided with a mounting frame A, and the mounting frame A is composed of a horizontal plate, an arc plate and symmetrically arranged vertical rods, and a rotary motor is installed at the top of the mounting frame A.

[0010] Preferably, a pulley set is fitted onto the outer surface of the output end of the rotary motor and the outer surface of one of the support shafts, and a gear set B is fitted onto the outer surface of the output end of the rotary motor and the outer surface of the other support shaft.

[0011] Preferably, the stabilizing plate is configured as an arc-shaped structure, and two sets of the stabilizing plate are symmetrically arranged about the central axis of the roller press body.

[0012] Preferably, the front end of the roller press body is provided with a mounting frame B, and a drive motor connected to one of the pressure rollers via a coupling is mounted on the top of the mounting frame B.

[0013] Preferably, a gear set A is provided at one end of the two pressure rollers extending to the outside of the main body of the roller press, and the gear set A consists of a driving gear and a driven gear.

[0014] In summary, the present invention has the following main advantages:

[0015] This invention features a dispersing plate and a stabilizing mechanism. The dispersing plate, with its inverted V-shaped structure, disperses the raw material to both sides, allowing it to fall onto the stabilizing plate, thus providing initial buffering. When the rotary motor operates, its output, driven by gear set B and pulley set, drives two support shafts to rotate in opposite directions. This facilitates the stable delivery of the dispersed raw material to the inclined surface inside the roller press body via the sleeve and the arc-shaped stabilizing plate, achieving further buffering. Simultaneously, the raw material slides steadily down the inclined surface, significantly reducing the impact on the raw material and achieving stable feeding. This effectively reduces feeding fluctuations, stabilizes the raw material composition, and prevents dust generation, making the raw material roller press convenient to use.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] A raw material roller press with stable feeding capability, as shown in Figures 1 and 4, includes a roller press body 1, a feed hopper 2, and a discharge hopper 3. The feed hopper 2 is located at the top of the roller press body 1, and the discharge hopper 3 is located at the bottom of the roller press body 1. A roller pressing mechanism 4 is installed through the inner side of the roller press body 1 below the feed hopper 2. The roller pressing mechanism 4 includes a pressure roller 401, a drive motor 402, and a gear set A403. The pressure roller 401 is rotatably connected to the inner side of the roller press body 1 via bearings. The bottom end of the inner side of the roller press body 1 is set with an inclined structure. A mounting frame B8 is provided at the front end of the roller press body 1. The top of the mounting frame B8 is equipped with a drive motor 402 connected to one of the pressure rollers 401 via a coupling. A gear set A403 is provided at one end of the two pressure rollers 401 extending to the outer side of the roller press body 1, and the gear set A403 consists of a driving gear and a driven gear.

[0024] Referring to Figures 1 and 4, when processing raw materials, the raw materials are fed into the main body 1 of the roller press through the feed hopper 2. At the same time, the drive motor 402 is started, so that the output end of the drive motor 402 drives the mutually cooperating pressure roller 401 to rotate in the opposite direction under the action of the gear set A403. Thus, the roller pressing operation of the raw materials can be realized through the pressure roller 401.

[0025] Referring to Figures 3 and 4, a dispersing plate 5 is provided on the inner side of the roller press body 1 below the pressure roller 401. The dispersing plate 5 is configured with an inverted "V" shape. The two ends of the dispersing plate 5 are welded to the roller press body 1. Because the dispersing plate 5 is configured with an inverted V shape, the raw material can be dispersed to both sides and fall onto the stabilizing plate 605 through the dispersing plate 5, thereby providing initial buffering for the raw material.

[0026] Referring to Figures 1, 2, and 4, a stabilizing mechanism 6 is provided through the inner side of the roller press body 1, below the dispersing plate 5. The stabilizing mechanism 6 includes a rotary motor 601, a gear set B602, a pulley set 603, a support shaft 604, a stabilizing plate 605, and a sleeve 606. The support shaft 604 is rotatably connected to the inside of the roller press body 1 via bearings. The sleeve 606 is fitted onto the outer surface of the support shaft 604. The stabilizing plate 605 is equidistantly positioned on the outer surface of the sleeve 606. The front end of the roller press body 1 is... The device includes a mounting frame A7, which consists of a horizontal plate, an arc-shaped plate, and symmetrically arranged vertical rods. A rotary motor 601 is mounted on the top of the mounting frame A7. A pulley set 603 is fitted onto the outer surface of the output end of the rotary motor 601 and the outer surface of one of the support shafts 604. A gear set B602 is fitted onto the outer surface of the output end of the rotary motor 601 and the outer surface of another support shaft 604. The stabilizing plate 605 is configured with an arc-shaped structure, and two sets of stabilizing plates 605 are symmetrically arranged about the central axis of the roller press body 1.

[0027] Referring to Figures 1, 2, and 4, when the rotary motor 601 is working, the output end of the rotary motor 601 drives the two support shafts 604 to rotate in opposite directions under the action of the gear set B602 and the pulley set 603. This allows the dispersed raw material to be stably fed onto the inclined surface inside the main body 1 of the roller press through the cooperation of the sleeve 606 and the arc-shaped stabilizing plate 605, thereby achieving further buffering and allowing the raw material to slide stably along the inclined surface. This greatly reduces the impact on the raw material, thereby achieving stable feeding, effectively reducing the fluctuation of raw material feeding, stabilizing the raw material composition, and achieving the purpose of preventing dust. This makes the raw material roller press more convenient to use.

[0028] The working principle of this utility model is as follows: When using the raw material roller press with stable feeding, the raw material is fed into the roller press body 1 through the feed hopper 2. At the same time, the drive motor 402 is started, so that the output end of the drive motor 402 drives the mutually cooperating pressure roller 401 to rotate in the opposite direction under the action of the gear set A403. Thus, the raw material can be rolled by the pressure roller 401. During this process, the raw material can be dispersed to both sides by the inverted V-shaped dispersion plate 5 and fall onto the stabilizing plate 605. At the same time, the rotary motor 601 is started, so that the output end of the rotary motor 601 drives the two support shafts 604 to rotate in the opposite direction under the action of the gear set B602 and the pulley set 603. This makes it easy to stably feed the dispersed raw material onto the inclined surface inside the roller press body 1 through the cooperation of the sleeve 606 and the arc-shaped stabilizing plate 605, and make the raw material slide down the inclined surface stably. This greatly reduces the impact on the raw material, thereby achieving stable feeding.
