Description

Technical Field

[0001] The present invention belongs to the technical field of conveyors, and more specifically, relates to a belt conveyor for metallurgical powder preparation. Background Art

[0002] During the process of metallurgical powder preparation, the uniformity of raw material distribution on the conveyor belt and the stability during the conveying process have crucial impacts on the quality of the final product.

[0003] When traditional belt conveyors handle metallurgical powder, the situation of uneven raw material distribution often occurs. Excessive raw material accumulation will increase the load on the conveyor belt, leading to increased wear and shortened service life of the conveyor belt. At the same time, it will also affect subsequent processing steps, resulting in product quality defects. Moreover, the existing feeding methods often cannot accurately supplement the raw materials to the insufficient positions. In the face of the problem of feeding pipe blockage caused by the complex characteristics of metallurgical powder, vibration motors are usually used to assist in feeding. However, vibration motors not only require complex electrical control and programming operations, but also are extremely prone to frequent failures due to dust erosion of electrical components in the multi-dusty metallurgical workshop environment. The maintenance cost is high and the downtime is long.

[0014] As a preferred embodiment of the present invention, a synchronous shaft is installed at the rotation center of the driving roller.

[0019] The present invention has the following beneficial effects compared with the prior art:

[0020] The belt conveyor for preparing metallurgical powder of the present invention has innovative and efficient designs and excellent functions in terms of raw material processing. When the conveyor belt is running, if there is too much powder accumulation, the shovel plate will accurately remove the excess powder. These removed powders are not wasted but are cleverly stored temporarily and then automatically conveyed to the position where the raw materials are insufficient, realizing the intelligent adjustment and replenishment of the raw material distribution on the conveyor belt; during the feeding process, to address the problem of clogging of the feeding pipe that may be caused by the complex characteristics of metallurgical powder, the turntable at the center of the conveyor belt drive rotates. When the convex blocks with different spacings on the turntable rotate uniformly, they sequentially press the rocker, causing the hammering rod at the other end of the rocker to strike the feeding pipe in a variable-frequency manner. This variable-frequency knocking mode can more comprehensively and efficiently break the agglomeration and bridging structures of the powder near the discharge port, assist in discharging materials, and ensure that the feeding pipe can stably supply materials even under complex working conditions, guaranteeing the efficient operation of the automatic feeding function; at the same time, as the rocker swings, it drives the pressing plate to move downward, compacting the raw materials on the conveyor belt. The compacted raw materials are not easily blown away by the wind. Moreover, the nozzle group installed at the bottom of the pressing plate will completely sink into the raw materials as the pressing plate moves downward. The nozzle group connected to the spraying system through the quick connector can fully and repeatedly wet the raw materials. The combined effects of compaction and wetting not only enhance the bonding force between powder particles, optimize the quality of powder forming in subsequent processing, but also enable the powder to participate more fully and uniformly in reactions in subsequent chemical reactions or physical treatment processes, greatly improving the stability and uniformity of product quality and comprehensively enhancing the production efficiency and product quality of metallurgical powder preparation.

The position of the discharge port of the feeding pipe 25 is flush with the shovel plate 22. This design enables the powder in the temporary storage cover 2 to be smoothly transported to the position where the conveyor belt needs to replenish raw materials through the feeding pipe 25 under the action of gravity, realizing efficient and accurate automatic feeding.

[0044] Embodiment 2:

[0045] Based on the difference between Embodiment 1 and this embodiment: As Figures 1 to 8 shown, a guiding frame 221 is installed on the side wall of the temporary storage cover 2. The guiding frame 221 is in a bent state. This unique bent design can better guide the running track of the conveyor belt 23. A partition plate 222 is installed at the inclined position of the guiding frame 221. The partition plate 222 can further optimize the distribution of the powder on the conveyor belt, ensuring the stability of powder transportation. The conveyor belt 23 is attached to the surface of the guiding frame 221, and the guiding frame 221 and the temporary storage cover 2 are connected to each other. A V-shaped guiding strip 223 is installed on the guiding frame 221. The V-shaped guiding strip 223 is attached to the upper surface of the conveyor belt 23. The V-shaped guiding strip 223 can distribute the transported raw materials on both sides of the temporary storage cover 2.

[0046] As Figures 1 to 8As shown, in the specific implementation manner, a driving roller 231 and a driven roller 232 are respectively rotatably installed inside the guiding frame 221. The driving roller 231 and the driven roller 232 are respectively sleeved at both ends of the conveyor belt 23, providing power support for the operation of the conveyor belt 23. A reversing roller 234 is lapped at the bottom of the conveyor belt 23, and the reversing roller 234 is installed on the guiding frame 221. A guiding roller 233 corresponding to the reversing roller 234 is further provided inside the conveyor belt 23, and the guiding roller 233 is rotatably installed on the side wall of the guiding frame 221. The coordinated action of these rollers ensures that the conveyor belt 23 can operate stably and smoothly, improving the efficiency and reliability of powder transportation.

[0047] As Figures 1 to 8 shown, further, a synchronizing shaft 242 is installed at the rotation center of the driving roller 231.

The driving motor 24 provides stable power for the entire system, ensuring that each component can operate efficiently.

[0048] Embodiment 3:

[0049] Based on Embodiment 2, the difference from this embodiment is that as Figures 1 to 8 shown, a clamping shaft 321 is installed at the rotation center of the seesaw 32. A mounting seat 323 is rotatably arranged on the clamping shaft 321, and the mounting seat 323 is installed on the side wall of the temporary storage cover 2. A torsion spring 322 is sleeved on the clamping shaft 321. One end of the torsion spring 322 is clamped on the seesaw 32, and the other end is clamped on the mounting seat 323. A hammer head 331 is installed at the end of the hammering rod 33, and the end of the hammer head 331 corresponds to the position of the discharge port of the replenishing pipe 25. When the convex block 31 presses the seesaw 32, the torsion spring 322 is twisted synchronously, storing elastic potential energy; when the convex block 31 and the seesaw 32 are separated, the torsion spring 322 releases the elastic potential energy, driving the seesaw 32 to quickly rotate and reset, and then driving the hammering rod 33 to hammer the discharge port of the replenishing pipe 25. A hammer head 331 is installed at the end of the hammering rod 33, and the end of the hammer head 331 corresponds to the position of the discharge port of the replenishing pipe 25, ensuring the accuracy of hammering and effectively preventing the blockage of the discharge port of the replenishing pipe 25.

[0050] As Figures 1 to 8As shown, in the specific implementation, a quick connector 411 is installed above the nozzle group 41. The quick connector 411 is connected to the spraying system, providing the liquid required for wetting the powder for the nozzle group 41 conveniently and quickly. A number of pairs of nozzles are provided on the surface of the nozzle group 41, enabling comprehensive and uniform wetting of the powder. A number of pairs of pull rods 421 are installed on the top of the pressing plate 4. Synchronous plates 42 are installed on the number of pairs of pull rods 421. Slide rods 423 are installed on both side walls of the synchronous plate 42. A strip-shaped groove 424 is provided at the end of the rocker 32. The slide rod 423 is slidably arranged on the inner wall of the strip-shaped groove 424. When the rocker 32 swings, the synchronous plate 42 and the pressing plate 4 can be accurately pulled to move vertically through the slide rod 423, realizing the compaction operation of the powder.

[0051] As Figures 1 to 8 shown, further, a limiting plate 43 is slidably arranged on the slide rod 423. A limiting seat 431 is installed at the bottom of the limiting plate 43. The limiting seat 431 is connected to the ground. A limiting groove 433 is provided on the limiting plate 43. The limiting groove 433 is in a vertical state. A slider 422 is slidably arranged on the limiting groove 433. The slider 422 is fixedly installed on the side wall of the slide rod 423. A limiting rod 432 is vertically installed at the end of the limiting groove 433. The limiting rod 432 movably penetrates through the slider 422. A limiting spring 434 is sleeved on the side wall of the limiting rod 432. One end of the limiting spring 434 is clamped on the slider 422, and the other end of the limiting spring 434 is clamped on the inner wall of the limiting groove 433. This design of the limiting structure can effectively control the moving range of the slide rod 423, ensuring the stability and accuracy of the pressing plate 4 during the powder compaction process. At the same time, through the elastic action of the limiting spring 434, it plays a buffering and adjusting role in the movement of the pressing plate 4, further optimizing the compaction effect of the powder.

[0052] The implementation principle of a belt conveyor for metallurgical powder preparation according to the present invention is as follows:

[0053] The operator first pours the raw materials onto the conveyor belt body 1, and the raw materials accumulate in a mountain shape on the conveyor belt body. The side enclosing plate 13 can effectively prevent the raw materials from scattering disorderly to both sides of the conveyor belt, avoiding waste of raw materials and pollution to surrounding equipment and the environment, and reducing the cleaning and maintenance costs. The guiding plate 131 is in an inclined state, guiding the raw materials to accumulate centrally on the conveyor belt, ensuring a reasonable initial distribution of the raw materials, laying a foundation for subsequent smooth transportation and uniform processing, and reducing problems such as transportation jams and uneven processing caused by chaotic initial distribution of the raw materials.

[0054] When the conveyor belt body 1 is running, if there is too much powder accumulation, the shovel plate 22 installed on the temporary storage cover 2 will accurately remove the excess powder, avoiding additional burden on the operation of the conveyor belt, ensuring its stable operation, reducing the wear of the conveyor belt, and extending its service life. The removed powder is conveyed to the temporary storage cover 2 through the conveyor belt 23 for temporary storage, achieving preliminary intelligent adjustment of the raw material quantity, maintaining the smoothness of the production process, and preventing interference with subsequent processing steps.

[0055] The feeding pipe 25 with an inclined bottom in the temporary storage cover 2, under normal working conditions, automatically conveys the powder to the place where there is less raw material on the conveyor belt relying on its own inclination angle and the gravity of the powder in the temporary storage cover 2, realizing automatic replenishment. This greatly improves the uniformity of the powder distribution on the conveyor belt, ensuring that the powder can evenly participate in the process during subsequent processing. In the preparation of metallurgical powder, uniform raw material distribution can reduce product quality defects. For example, in the pressing process, the density of the green body is consistent, and during sintering, each part of the green body shrinks evenly, reducing internal defects of the product, increasing the yield rate, reducing waste products, lowering production costs, enhancing market competitiveness, while ensuring the stability and continuity of the preparation process, avoiding production interruption, and improving production efficiency.

[0056] Moreover, due to the complex characteristics of metallurgical powder, affected by uneven particle size, humidity change, electrostatic adsorption and conveying environmental factors, there is a tendency of powder agglomeration and bridging near the discharge port of the feeding pipe 25. At this time, the turntable 3 at the driving center of the conveyor belt 23 plays a key role. When several pairs of bumps 31 with different spacings on the turntable 3 rotate at a constant speed, they press the rocker 32 in turn. The rocker 32 can rotate, and the torsion spring 322 is twisted synchronously. When the bump 31 and the rocker 32 are separated, the rocker 32 is driven by the torsion spring 322 to rotate and reset, and then drives the hammering rod 33 to hammer the discharge port of the feeding pipe 25.

[0057] Due to the different spacings of the bumps 31, the time intervals for lifting the rocker 32 are different, resulting in different frequencies of the hammer rod 33 at the other end of the rocker 32 hitting the refill pipe 25. After the bump 31 separates from the rocker 32, the torsion spring 322 installed on the card shaft 321 at the rotation center of the rocker 32 releases the torsion force and quickly pulls the rocker 32 back to the initial position to prepare for the next pressing of the bump 31. This knocking mode with such a frequency and rapid reset can, compared with the knocking of a single frequency, more comprehensively and efficiently break the agglomeration and bridging structures of the powder near the discharge port, adapt to the clogging characteristics of different types of metallurgical powders, reduce the clogging of the discharge port, ensure that the refill pipe 25 can continuously and stably convey the powder by gravity under complex working conditions, and ensure the efficient operation of the automatic replenishment of raw materials function. This vibration-assisted feeding design reduces the frequency of manual cleaning of the clogging of the refill pipe, reduces the labor cost and the equipment downtime, and improves the overall production efficiency. Compared with the prior art that achieves the above functions through a vibration motor, the mechanical structure design of the present invention is completely based on the ingenious cooperation between mechanical components and does not require additional complex electrical control components and programming operations. In the actual production environment, there are often a large amount of dust in the metallurgical powder preparation workshop. When the vibration motor is in such an environment for a long time, the internal electrical components are easily eroded by the dust, resulting in frequent failures, high maintenance costs and long downtime. In contrast, the pure mechanical structure of the present invention has stronger stability, is less affected by environmental factors, and hardly needs to worry about the interference of dust on the operation of the structure, greatly reducing the maintenance difficulty and cost.

[0058] When the rocker 32 swings, the rocker 32 pulls the slide rod 423 to slide in the strip-shaped groove 424. The slide rod 423 itself can move vertically, and then pulls the synchronous plate 42 and the pressing plate 4 to move vertically. When the pressing plate 4 moves downward to compact the powdery material in a mountain shape on the conveyor belt, it ensures that the powder is distributed more tightly and evenly. The nozzle group 41 installed at the bottom of the pressing plate 4 is completely immersed in the powder, and the nozzle group 41 connected to the spraying system through the quick connector 411 fully wets the powder, meeting the specific requirements for raw material treatment in the preparation of metallurgical powders. The compaction and wetting act synergistically to enhance the bonding force between powder particles, optimize the subsequent powder forming quality, and the uniform wetting helps the powder to participate in the reaction more fully and uniformly in the subsequent chemical reaction or physical treatment process, improving the stability and uniformity of the product quality.

[0059] When the pressing plate 4 is connected to the rocker 32 through the pull rod 421, the synchronous plate 42 and the slide rod 423 and moves up and down, the slide rod 423 slides in the strip-shaped groove 424 to ensure the stable movement of the pressing plate 4. The limiting structure composed of the limiting plate 43, the limiting seat 431, the slider 422, the limiting groove 433, the limiting rod 432 and the limiting spring 434 further limits the moving range of the slide rod 423 to prevent the pressing plate 4 from moving excessively and damaging the equipment or affecting the powder treatment effect. This stability and limiting design extends the service life of the key components of the equipment, reduces the equipment maintenance cost, and enhances the reliability and safety of the equipment operation as a whole.
