Description

Technical Field

[0001] This invention relates to the field of vertical mill technology, specifically to a vertical mill feed hopper with a stable material flow conveying function. Background Technology

[0002] Vertical roller mills are grinding equipment widely used in industries such as cement, power, metallurgy, chemical, and non-metallic minerals. During the operation of a vertical roller mill, the feed hopper is an important component for material storage and transportation.

[0003] Currently, the existing feed hoppers for vertical mills have shortcomings in use. When materials enter the feed hopper, they tend to fall in a concentrated manner, resulting in uneven feeding. Moreover, the impact force of the falling materials is relatively large, causing significant wear on the inner wall of the feed hopper. Furthermore, it is impossible to achieve stable flow and discharge in the future, which shortens the service life of the feed hopper. At the same time, problems such as material leakage may occur during the feeding process, thereby affecting the working environment and the production efficiency of the vertical mill. Summary of the Invention

[0004] The purpose of this invention is to provide a vertical mill feed hopper with a stable material flow conveying function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a vertical mill feeding hopper with material steady flow conveying function, comprising a processing hopper, the bottom of which is connected to a feeding hopper, the bottom of which is connected to a discharge pipe, a control valve being movably installed on the surface of the discharge pipe, support columns being installed on both sides of the bottom of the feeding hopper, a diversion component being installed at the feeding part of the inner cavity of the feeding hopper, a buffer discharge component being installed below the diversion component, a conical discharge hopper being fixedly installed at the bottom of the inner cavity of the feeding hopper, and a sealing component being installed on the right side of the inner cavity of the feeding hopper; The sealing assembly includes an electric cylinder, the output end of which is fixedly equipped with an adjusting pull plate. The upper bent portion of the adjusting pull plate extends through to the interior of the feeding hopper and is rotatably equipped with a sealing baffle. The sealing baffle is designed with an inclination.

[0006] As a preferred embodiment, the diversion assembly includes diversion plates, which are arranged at equal intervals at the discharge section at the top of the discharge hopper. An upper inclined plate is fixedly installed on the top left side of the inner cavity of the discharge hopper, and an inclined baffle is installed on the lower right side of the upper inclined plate and on the inner wall of the discharge hopper. The upper inclined plate and the inclined baffle are staggered.

[0007] As a preferred embodiment, a vertical rod is fixedly installed on the right side of the top of the inner cavity of the feeding hopper, and a limit sleeve is fixedly installed at the lower end of the vertical rod. The limit sleeve is sleeved on the outside of the adjusting pull plate and slidably connected.

[0008] As a preferred embodiment, a limiting component is installed at the top of the inner cavity of the feeding hopper and on the left side of the upright. The limiting component includes a fixed frame, a limiting spring is fixedly installed at the top of the inner cavity of the fixed frame, a movable seat is fixedly installed at the lower end of the limiting spring, and a sealing inclined plate is fixedly installed at the lower end of the movable seat. The inclined surface of the sealing inclined plate is in contact with the inclined surface of the sealing baffle.

[0009] As a preferred embodiment, the end of the conical discharge hopper is sealed to the inner wall of the discharge bin, the lower end of the conical discharge hopper is connected to the interior of the discharge pipe, and the adjusting end of the control valve is connected by a sealing ball.

[0010] As a preferred embodiment, the buffer unloading assembly includes a support spring, an adjusting plate is mounted on the lower end of the support spring, and a buffer plate is mounted on the right end of the adjusting plate.

[0011] As a preferred embodiment, the lower end of the buffer plate extends to the lower left of the inclined baffle, and the relative positions of the lower ends of the buffer plate and the inclined baffle can form a conical opening.

[0012] As a preferred embodiment, positioning plates are fixedly installed at both ends of the diversion plate, and the outside of the positioning plates is connected to the inside of the feeding hopper. There is a certain gap between the lower end of the diversion plate and the top of the upper inclined plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, by setting up a diversion plate, an upper inclined plate, and an inclined baffle, can initially divert the material entering the discharge hopper, making the material evenly dispersed and avoiding concentrated falling. The staggered distribution of the upper inclined plate and the inclined baffle further guides the flow of the material, making the material move downward more evenly, thereby achieving stable material flow and improving the uniformity of discharge. The support spring and buffer plate can buffer the falling material, reduce the impact of the material on the inner wall of the discharge hopper and the conical discharge hopper, reduce wear, and extend the service life of the discharge hopper and the conical discharge hopper.

[0014] 2. The present invention further guides the flow direction of materials by setting up a buffer plate. After the material passes through the buffer plate and is blocked and guided, it can flow downward more smoothly. The conical opening formed by the relative positions of the buffer plate and the lower end of the inclined baffle allows the material to form a relatively stable flow when passing through this area, avoiding disorder or blockage of the material during the unloading process, ensuring stable material conveying and improving the working efficiency of the unloading hopper.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example 1:

[0019] Please see Figure 1 As shown, the present invention provides a vertical mill feeding bin with material steady flow conveying function, including a processing bin 1, a feeding bin 2 connected to the bottom of the processing bin 1, a discharge pipe 3 connected to the bottom of the feeding bin 2, a control valve 4 movably installed on the surface of the discharge pipe 3, support columns 5 installed on both sides of the bottom of the feeding bin 2, a diversion component 6 installed at the feeding part of the inner cavity of the feeding bin 2, a buffer discharge component 7 installed below the diversion component 6, a conical discharge hopper 8 fixedly installed at the bottom of the inner cavity of the feeding bin 2, and a sealing component 9 installed on the right side of the inner cavity of the feeding bin 2; The sealing assembly 9 includes an electric cylinder 901. An adjusting pull plate 902 is fixedly installed at the output end of the electric cylinder 901. The upper bent part of the adjusting pull plate 902 extends through and into the interior of the feeding hopper 2, where a sealing baffle 903 is rotatably installed. The sealing baffle 903 has an inclined design. Example 2:

[0020] Based on Embodiment 1, the present invention is as follows: Figure 3 As shown, the flow diversion assembly 6 includes a flow diversion plate 601, which is arranged at equal intervals at the discharge section at the top of the discharge hopper 2. An upper inclined plate 602 is fixedly installed on the top left side of the inner cavity of the discharge hopper 2. An inclined baffle 603 is installed on the lower right side of the upper inclined plate 602 and on the inner wall of the discharge hopper 2. The upper inclined plate 602 and the inclined baffle 603 are staggered. A vertical rod 10 is fixedly installed on the right side of the top of the inner cavity of the discharge hopper 2. A limiting sleeve 11 is fixedly installed at the lower end of the vertical rod 10. The limiting sleeve 11 is sleeved on the outside of the adjusting pull plate 902 and slidably connected.

[0021] Adopting such Figure 1 The technical solution shown has diverter plates 601 arranged at equal intervals at the discharge section at the top of the feeding bin 2. Their main function is to initially disperse the material entering the feeding bin 2 from above. When the material enters the feeding bin 2 through the processing bin 1, the diverter plates 601 divide the concentrated material flow into multiple smaller material flows, allowing the material to be more evenly distributed across the cross-section of the feeding bin 2. This prevents material from concentrating in one area and avoids local accumulation or blockage, creating favorable conditions for stable subsequent material conveying and processing, improving the uniformity of material discharge and the stability of equipment operation. The upper inclined plate 602 and the inclined baffle 603 are staggered, and this structural design further guides the material flow path. The material initially dispersed by the diverter plates 601 falls onto the upper inclined plate 602. Because the upper inclined plate 602 is inclined, the material will flow along the upper inclined plate 602... As the material slides down the inclined surface, it changes direction during the descent and continues to flow downward from the inclined baffle 603. In this way, the movement trajectory of the material becomes more complex and dispersed, further ensuring that the material can move downward evenly and avoiding the large impact force on the bottom of the discharge bin 2 caused by the material falling directly vertically. At the same time, it also helps to achieve stable material flow and allows the material to enter the subsequent processing stage more orderly. In the sealing assembly 9, the electric cylinder 901 drives the adjusting pull plate 902 to move, thereby driving the sealing baffle 903 to achieve the sealing operation of the discharge bin 2. The presence of the limit sleeve 11 ensures that the adjusting pull plate 902 can only slide in a straight line along the direction limited by the upright 10, preventing the adjusting pull plate 902 from deviating or shaking during the movement, thereby ensuring that the sealing baffle 903 can accurately reach the predetermined position and achieve a good sealing effect.

[0022] Secondly, in the technical solution, a limiting component 12 is installed at the top of the inner cavity of the feeding hopper 2 and on the left side of the upright 10. The limiting component 12 includes a fixed frame 1201. A limiting spring 1202 is fixedly installed at the top of the inner cavity of the fixed frame 1201. A movable seat 1203 is fixedly installed at the lower end of the limiting spring 1202. A sealing inclined plate 1204 is fixedly installed at the lower end of the movable seat 1203. The inclined surface of the sealing inclined plate 1204 is in contact with the inclined surface of the sealing baffle 903. The end of the conical discharge hopper 8 is sealed and in contact with the inner wall of the feeding hopper 2. The lower end of the conical discharge hopper 8 is connected to the interior of the discharge pipe 3. The adjusting end of the control valve 4 is connected by a sealing ball. The buffer unloading component 7 includes a support spring 701. An adjusting plate 702 is installed at the lower end of the support spring 701. A buffer plate 703 is installed at the right end of the adjusting plate 702.

[0023] Its adoption is as follows Figure 1 The technical solution shown has the inclined surface of the sealing inclined plate 1204 in contact with the inclined surface of the sealing baffle 903. When the sealing baffle 903 performs a sealing action under the drive of the electric cylinder 901, the limit spring 1202 will give the movable seat 1203 a downward elastic force, so that the sealing inclined plate 1204 is pressed tightly on the sealing baffle 903. This can further fill the gap that may exist between the sealing baffle 903 and the inner wall of the feeding bin 2, enhance the sealing effect, effectively prevent material leakage, ensure the sealing of the feeding bin during the working process, avoid material overflow and pollution of the working environment, and also reduce material waste. The limit spring 1202 can adapt to this deformation through its own extension and contraction, still maintaining the tight contact between the sealing inclined plate 1204 and the sealing baffle 903, ensuring that the sealing performance is not affected. This allows the feeding bin 2 to maintain a good sealing state under complex working conditions, improving the stability and reliability of the equipment. When material falls from above and impacts the buffer plate 703, the support spring 701 will compress and deform, absorbing the impact force of the falling material. This effectively reduces the direct impact of the material on the bottom of the discharge bin 2 and the conical discharge hopper 8 and other components, reduces the risk of wear and damage to the equipment caused by large impact forces, and extends the service life of the equipment. Example 3:

[0024] The present invention is as follows Figures 1-6 As shown, the lower end of the buffer plate 703 extends to the lower left of the inclined baffle 603. In addition, the lower ends of the buffer plate 703 and the inclined baffle 603 can form a conical opening. Positioning plates are fixedly installed at the front and rear ends of the diversion plate 601, and the outside of the positioning plates is connected to the inside of the discharge bin 2. There is a certain gap between the lower end of the diversion plate 601 and the top of the upper inclined plate 602.

[0025] By adopting the above technical solution, the buffer plate 703 further guides the flow direction of the material. After being blocked and guided by the buffer plate 703, the material can flow downward more smoothly. The conical opening formed by the relative positions of the buffer plate 703 and the lower end of the inclined baffle 603 enables the material to form a relatively stable flow when passing through this area, avoiding disorder or blockage of the material during the unloading process, ensuring stable material conveying, and improving the working efficiency of the unloading bin 2.

[0026] The working principle of this invention is as follows: Material enters the discharge bin 2 from the processing bin 1 and first encounters the diversion plate 601. The diversion plate 601 divides the concentrated material flow into multiple smaller material flows, so that the material is initially evenly distributed on the cross-section of the discharge bin 2. Then, the dispersed material falls onto the upper inclined plate 602. Due to the inclined design of the upper inclined plate 602, the material will slide down along the upper inclined plate 602. During the sliding process, the material will change direction and continue to flow downward from the inclined baffle 603, further realizing the dispersion and even distribution of the material. After being diverted, the material continues to fall and impacts the adjusting plate 702. The support spring 701 supports the buffer plate 703 by squeezing it through the adjusting plate 702, which absorbs the impact force of the falling material and plays a buffering role, reducing the direct impact of the material on the discharge bin 2, the bottom of the conical discharge hopper 8, and other components. When sealing of the discharge hopper 2 is required, the electric cylinder 901 is activated. The output end of the electric cylinder 901 drives the adjusting plate 902 to move. The sealing baffle 903, which is rotatably installed on the upper bent part of the adjusting plate 902, will rotate with the movement of the adjusting plate 902. When the sealing baffle 903 moves to the left and its lower end abuts against the upper inclined plate 602, the initial sealing of the discharge hopper 2 can be achieved. At this time, the limit spring 1202 gives the movable seat 1203 a downward elastic force, so that the sealing inclined plate 1204 at the lower end of the movable seat 1203 presses tightly against the inclined surface of the sealing baffle 903, further filling any gaps that may exist between the sealing baffle 903 and the inner wall of the discharge hopper 2. The material that has been buffered and stabilized will fall into the conical discharge hopper 8. The end of the conical discharge hopper 8 is sealed and fitted against the inner wall of the discharge hopper 2. Its gradually narrowing diameter can guide the material to be discharged smoothly into the discharge pipe 3.
