Description

Technical Field

[0001] This utility model relates to the field of pellet processing technology, and in particular to a pellet powder briquetting machine. Background Technology

[0002] In the production of alkali pellets, two types of additives are generally used to ensure the alkalinity of the finished pellets: bentonite and limestone. However, large dosages of these additives can easily lead to insufficient strength in the green pellets, making them brittle and prone to cracking, resulting in low production efficiency, increased system dust, and unstable product quality. By optimizing the additive ratio and adding suitable high-pressure roller mills and pelletizing equipment, the compressive strength and wear resistance of the green pellets can be effectively improved, ensuring the alkalinity of the finished pellets meets standards, while simultaneously increasing production efficiency and product quality.

[0003] For example, patent application number CN201920522187.X discloses an iron ore powder resource utilization device, including a briquetting machine housing. A first motor is fixedly installed on the top right side of the briquetting machine housing. A main pressure roller is arranged on the right side of the top rear side of the inner wall of the briquetting machine housing, and an auxiliary pressure roller is arranged on the left side of the main pressure roller. During processing, this type of briquetting equipment requires feeding powder into the feed inlet at the top of the briquetting equipment. The powder fed into the feed inlet falls between the two pressure rollers. The two pressure rollers rotate to press the powder into shape. A limiting plate is generally set on the inner side of the discharge port, directly opposite the pressure rollers. The limiting plate is used to guide the powder pellets, allowing the powder to fall orderly between the two pressure rollers. However, since the limiting plates are mostly fixed, the size of the opening between the two limiting plates is difficult to adjust. When too much powder is added at once, blockage can easily occur between the two limiting plates, leading to a decrease in briquetting efficiency. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a pelletizing machine for briquetting powder, thereby overcoming the shortcomings of existing methods.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a pellet powder briquetting machine, including a machine box, a feeding port at the upper end of the machine box, a discharge port at the lower end of the machine box, and the feeding port and the discharge port are connected to the machine box;

[0006] The machine housing has two interlocking pressure rollers inside. The two ends of the pressure rollers are rotatably connected to the machine housing. Above the pressure rollers are inclined guide plates. The two inclined guide plates are placed in a V-shape to guide the powder between the two pressure rollers.

[0007] The left and right sides of the inclined guide plate are slidably connected to the inner wall of the feeding port. The outer side of the machine box is equipped with a ball pressing power assembly for controlling the rotation of the two pressure rollers and an adjustment and widening assembly for controlling the opening of the two inclined guide plates.

[0008] A further improvement is that the outer side of the pressure roller is provided with several ball grooves, and each ball groove is arranged in an array in the circumferential direction of the pressure roller axis.

[0009] A further improvement is that a first equipment box and a second equipment box are respectively provided on the front and rear sides of the chassis, and both the first equipment box and the second equipment box are fixedly connected to the chassis.

[0010] A further improvement is that: sliders are provided on the left and right sides of the inclined guide plate, and slide grooves are provided on the left and right sides of the machine box. One end of the slider is fixedly connected to the inclined guide plate, and the other end of the slider is slidably connected to the slide groove. A spring rod for supporting the slider is provided in the slide groove.

[0011] A further improvement is that the spring rod includes a spring rod, which is fixedly installed inside the housing. The spring rod passes through the slider and is slidably connected to the slider. A spring is sleeved on the outside of the spring rod, and the spring is fixedly installed between the slider and the groove wall.

[0012] A further improvement is that the ball-pressing power assembly includes a power unit and a transmission unit. The transmission unit includes two gears, which are rotatably disposed inside the second equipment box. The gears are fixedly connected to the pressure rollers via a connecting shaft, and the two gears mesh with each other. The power unit includes a motor, which is fixedly disposed inside the first equipment box, and the motor output end is fixedly connected to one of the pressure rollers.

The output end of the starting push rod is fixedly connected to the pressure plate. The left and right sides of the pressure plate are provided with inclined wedges, which are fixedly connected to the slider. The side of the pressure plate facing the inclined wedges is provided with an inclined wedge mating surface that mates with the inclined wedges.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The V-shaped inclined guide plates use their inclined surfaces to gather and guide the powder entering from the feeding port, ensuring that the powder falls precisely into the gap between the two pressure rollers. This prevents powder from shifting and causing missed areas during pressing. By adjusting the widening component, the opening distance of the inclined guide plates can be controlled, allowing the inclined guide plates to adapt to the guiding needs of powders with different particle sizes and flow rates, thus preventing powder from clogging above the two pressure rollers.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] according to Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this embodiment proposes a pellet powder briquetting machine, which includes a machine housing 1. The upper end of the machine housing 1 is provided with a feeding port 2, and the lower end of the machine housing 1 is provided with a discharge port 3. The feeding port 2 and the discharge port 3 are connected to the machine housing 1.

[0026] The inner side of the casing 1 is provided with two mutually cooperating pressure rollers 5. The two ends of the pressure rollers 5 are rotatably connected to the casing 1. An inclined guide plate 4 is provided above the pressure rollers 5. The two inclined guide plates 4 are placed in a V-shape to guide the powder between the two pressure rollers 5.

[0027] The operator feeds the powdered pellets to be pressed into the machine housing 1 through the feeding port 2. The two pressure rollers 5 rotate relative to each other under power, forming a squeezing force. After pressing the pellets, the formed pellets are discharged from the discharge port 3. The discharged pellets are then conveyed outwards by a conveying device for sorting.

[0028] The left and right sides of the inclined guide plate 4 are slidably connected to the inner wall of the feeding port 2. The outer side of the machine box 1 is provided with a ball pressing power assembly for controlling the rotation of the two pressure rollers 5 and an adjustment and widening assembly for controlling the opening of the two inclined guide plates 4.

[0029] During the feeding process, the V-shaped inclined guide plates 4 utilize their inclined surfaces to gather and guide the powder entering from the feeding port 2, ensuring that the powder falls precisely into the gap between the two pressure rollers 5. This prevents powder deviation and leakage during pressing, thus improving powder utilization. The inclined guide plates 4 are slidably connected to the inner wall of the feeding port 2, and the opening distance of the inclined guide plates 4 can be controlled by adjusting the widening component. This allows the inclined guide plates 4 to adapt to the guiding needs of powders with different particle sizes and flow rates, preventing powder from clogging above the two pressure rollers 5.

[0030] It is worth explaining in detail that the outer side of the pressure roller 5 is provided with several ball-shaped grooves 8, which are arranged in an array around the axis of the pressure roller 5. The ball-shaped grooves 8 at corresponding positions are staggered, that is, the center line of a ball-shaped groove 8 on one pressure roller 5 is aligned with the symmetrical center line of two adjacent ball-shaped grooves 8 on another pressure roller 5, and the axial rows and circumferential circles of the ball-shaped grooves 8 on the two pressure rollers 5 correspond one-to-one to form a mating group. When the two pressure rollers 5 rotate relative to each other to the contact position, the staggered ball-shaped grooves 8 together enclose and form a spherical cavity for material forming. The gap when the cavity is closed is smaller than the particle size of the material being pressed, ensuring that the material is fully compressed and formed.

[0031] It is worth explaining in detail that a first equipment box 6 and a second equipment box 7 are respectively provided on the front and rear sides of the chassis 1, and both the first equipment box 6 and the second equipment box 7 are fixedly connected to the chassis 1.

[0032] Specifically, sliders 10 are provided on the left and right sides of the inclined guide plate 4, and slide grooves 11 are provided on the left and right sides of the machine box 1. One end of the slider 10 is fixedly connected to the inclined guide plate 4, and the other end of the slider 10 is slidably connected to the slide groove 11. A spring rod for supporting the slider 10 is provided in the slide groove 11.

[0033] When adjusting the opening distance of the inclined guide plate 4, the inclined guide plate 4 drives the slider 10 to slide along the slide groove 11. The slide groove 11 provides a directional motion trajectory for the slider 10 to prevent the slider 10 from deviating. The spring rod generates an elastic force during the sliding of the slider 10, providing support and buffer for the slider 10, and keeping the position of the slider 10 stable after the adjustment is completed.

[0034] It is worth explaining in detail that the spring rod includes a spring rod 17, which is fixedly installed inside the housing 1. The spring rod 17 passes through the slider 10 and is slidably connected to the slider 10. A spring 18 is sleeved on the outside of the spring rod 17, and the spring 18 is fixedly installed between the slider 10 and the groove wall of the slide groove 11.

[0035] The spring rod 17 provides a sliding guide for the slider 10, restricts the movement direction of the slider 10, and ensures that the slider 10 slides only along the axial direction of the spring rod 17. When the slider 10 slides, it compresses or stretches the spring 18. The reaction force generated by the spring 18 provides a buffer for the slider 10, preventing the slider 10 from colliding violently with the groove wall of the slide 11. At the same time, after the adjustment is completed, the elastic force of the spring 18 keeps the slider 10 in a fixed position.

[0036] The ball pressing power assembly includes a power unit and a transmission unit. The transmission unit includes two gears 13, which are rotatably disposed inside the second equipment box 7. The gears 13 are fixedly connected to the pressing roller 5 through a connecting shaft, and the two gears 13 mesh with each other. The power unit includes a motor 9, which is fixedly disposed inside the first equipment box 6. The output end of the motor 9 is fixedly connected to one of the pressing rollers 5.

[0037] When the motor 9 operates, it drives the pressure roller 5 to rotate. The pressure roller 5 drives the gear 13 fixed to it to rotate through the connecting shaft. The two gears 13 mesh with each other, and the power is transmitted to the other gear 13, which in turn drives the other pressure roller 5 to rotate synchronously in the opposite direction, so as to realize the coordinated extrusion operation of the two pressure rollers 5.

[0038] The adjustment and widening assembly includes a starting push rod 14 and a pressure plate 15. The starting push rod 14 is fixedly installed on the upper end of the second equipment box 7, and the pressure plate 15 is slidably installed inside the second equipment box 7. The output end of the starting push rod 14 is fixedly connected to the pressure plate 15. The left and right sides of the pressure plate 15 are provided with inclined wedges 12, which are fixedly connected to the slider 10. The side of the pressure plate 15 facing the inclined wedges 12 is provided with an inclined wedge mating surface 16 that mates with the inclined wedges 12.

[0039] When the start push rod 14 is activated, its output end pushes the pressure plate 15 to slide in a straight line in the second equipment box 7; the wedge mating surface 16 of the pressure plate 15 contacts and interacts with the wedge 12, converting the linear motion of the pressure plate 15 into the lateral motion of the wedge 12, and the wedge 12 drives the slider 10 to slide along the slide groove 11, ultimately realizing the adjustment of the opening distance of the inclined guide plate 4.

[0040] How this application works:

[0041] During pressing, the motor 9 runs, which drives the pressure roller 5 to rotate. The pressure roller 5 drives the gear 13 fixed to it to rotate through the connecting shaft. The two gears 13 mesh with each other, and the power is transmitted to the other gear 13, which in turn drives the other pressure roller 5 to rotate synchronously in the opposite direction, so as to realize the coordinated pressing operation of the two pressure rollers 5.

[0042] During feeding, the V-shaped inclined guide plates 4 use their inclined surfaces to gather and guide the powder entering from the feeding port 2, ensuring that the powder falls precisely into the gap between the two pressure rollers 5. This prevents powder deviation and avoids leakage during pressing, thus improving powder utilization. By adjusting the widening component, the opening distance of the inclined guide plates 4 can be controlled, allowing the inclined guide plates 4 to adapt to the guiding needs of powders with different particle sizes and flow rates.
