Description

Technical Field

[0001] The present invention relates to the technical field of vertical mill equipment, and in particular to a vertical mill for preventing material adhesion. Background Art

[0002] A vertical mill is internally provided with grinding rollers and a grinding table. During the rotation of the grinding table, the grinding rollers can be driven to rotate synchronously. Materials are squeezed and crushed between the two to achieve an efficient and continuous powder-making process.

[0003] When processing materials with high humidity and viscosity such as slag, after the grinding rollers of the vertical mill are squeezed, the wet materials are easily adhered to the surface of the grinding rollers. And as the grinding rollers continue to rotate, the range of materials adhered to the surface of the grinding rollers gradually increases, and the thickness of the materials between the grinding rollers and the grinding table increases to form a "cake" shape. The vibration amplitude of the grinding rollers increases during the roller pressing process, affecting the normal operation of the equipment; some domestic enterprises are provided with scraping shovels at the upper ends of the grinding rollers to remove the materials adhered to the surface of the grinding rollers. However, simply setting static scraping shovels has limited cleaning effect and cannot achieve the predetermined cleaning purpose. Simply setting scraping shovels, the humidity of the materials and the surface of the grinding rollers is still relatively high, and the two will still adhere during the subsequent roller pressing process, affecting the long-term and effective operation of the equipment.

The cleaning device includes a cleaning mounting frame. A cleaning assembly rotatably connected thereto is installed at the end of the cleaning mounting frame. The cleaning assembly is located above one side of the grinding rollers and extends along the axis direction of the grinding rollers.

[0007] Preferably, the cleaning assembly includes a cleaning rotating shaft rotatably connected to the cleaning mounting frame. A cleaning mounting cylinder is fixedly connected to the surface of the cleaning rotating shaft. Cleaning strips are detachably fixedly connected to the surface of the cleaning mounting cylinder.

[0008] Preferably, the cleaning strips are distributed in a serpentine shape along the surface of the cleaning installation cylinder. A cleaning gap is provided between two adjacent parts of the serpentine cleaning strips, and the air-permeable opening is located within the cleaning gap.

[0009] Preferably, the driving device includes a driving installation box. An electric control device is fixedly connected to the surface of the driving installation box to control the rotation of the cleaning rotating shaft. A air-blowing component is arranged within the cleaning installation box. The air-blowing component includes an air-blowing baffle. An elastic air-blowing airbag is provided between the air-blowing baffle and the inner wall of the driving installation box. A air-blowing cam is fixedly connected to the surface of the cleaning rotating shaft. The air-blowing cam is located on one side of the air-blowing baffle and is matched with it. The air-blowing airbag is communicated with two air-blowing pipes. A first one-way valve is arranged within the air-blowing pipes. The end of the first air-blowing pipe is communicated with the air-permeable opening.

[0010] Preferably, the cleaning installation frame includes a first cleaning installation part and a second cleaning installation part. The first cleaning installation part and the second cleaning installation part slide linearly relative to each other. A control opening is formed in the inner wall of the first cleaning installation part. A control piston is hermetically slidably connected within the control opening. A control rod fixedly connected to the control piston is fixedly arranged on the side wall of the second cleaning installation part. The control opening is communicated with a first control pipe and a second control pipe. A second one-way valve is arranged within the first control pipe. An electric control valve is arranged within the second control pipe.

[0011] Preferably, a material guiding component is further arranged within the vertical mill chamber. A first material guiding plate is arranged at the upper end of the material guiding component, and a second material guiding plate is arranged at the lower end of the material guiding component.

[0012] Preferably, the material guiding component includes a material guiding cylinder body. An inclined first receiving plate and a second receiving plate are fixedly connected to the inner wall of the material guiding cylinder body.

[0013] Preferably, a dispersing blade is installed on the inner wall of the bottom end of the material guiding cylinder body. A driving component is arranged within the material guiding cylinder body to control the rotation of the dispersing blade.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. By setting the cleaning device to continuously rotate the cleaning component, it is possible to remove the materials with high humidity adhering to the surface of the grinding roller, avoiding the continuous adhesion of materials to the surface of the grinding roller and affecting the operation of the equipment. In particular, by setting the serpentine cleaning strips and providing ventilation openings between the cleaning strips, the serpentine cleaning strips can generate a tangential force on the surface of the grinding roller during rotation, controlling the adhered materials to move in a specific direction and enhancing the cleaning effect. On the one hand, the hot air blown out from the ventilation openings can generate a force on the surface of the grinding roller, enhancing the cleaning effect. On the other hand, it can dry the adhered materials and the surface of the grinding roller, reducing the moisture content of both, avoiding mutual adhesion during subsequent extrusion, and preventing material bonding, fundamentally solving the problem of material bonding on the surface of the grinding roller.

[0016] 2. By setting the cleaning mounting frame as a relatively sliding first cleaning mounting part and a second cleaning mounting part, the two can move linearly relative to each other. The elastic guiding component can play a buffering role, controlling the opening and closing of the electric control valve according to the amplitude of the grinding roller's vibration, enabling the cleaning component to move away from or close to the grinding roller, being able to select an appropriate cleaning mode according to the adhesion situation of the materials on the surface of the grinding roller, ensuring the cleaning effect on the grinding roller, and at the same time, when the adhesion of the materials on the surface of the grinding roller is not serious, achieving an appropriate cleaning state to extend the service life of related components and reduce costs.

[0017] 3. By setting the material guiding component, it can collect and guide the materials cleaned and dropped. And the material guiding component is inclined, so that the guided materials can be located between the grinding roller and the grinding disc more quickly to improve production efficiency. By setting the first receiving plate and the second receiving plate which are alternately inclined in the material guiding component, the moving time of the materials inside the material guiding component is extended, and under the action of the heat source, the materials can be deeply dried to ensure the dispersion effect. And by setting the dispersion blades, the dispersion effect of the materials can be further enhanced. At the same time, under the action of the dispersion blades, the hot air at the cleaning component can be driven to flow in a specific direction to further enhance the drying effect of the materials, and also can discharge the moisture in the material guiding component to create a dry drying environment.

Specific embodiments

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Refer to Figure 1-6 , a vertical mill for preventing material adhesion, including a vertical mill main body 1, a vertical mill chamber 101 is arranged inside the vertical mill main body 1, a vertical mill component 2 is arranged in the vertical mill chamber 101, the vertical mill component 2 includes a vertical mill mounting frame 201 and grinding rollers, the grinding rollers are installed on one side of the vertical mill mounting frame 201 and are rotatable therewith, the grinding rollers are located at the upper edge position of the grinding table, during the rotation of the grinding table, the material is located between the grinding table and the grinding rollers, and is crushed under the extrusion of the two, and the grinding rollers will rotate synchronously with the grinding table to achieve continuous and efficient extrusion and crushing for powder making; materials such as tailings and slag enter the vertical mill, due to their high humidity and certain viscosity, they adhere to the surface of the grinding rollers after extrusion, which affects the subsequent extrusion of the grinding rollers.

[0027] To solve the problem of sticky materials adhering to the surface of the grinding roller, a cleaning device 3 is installed on the side wall of the vertical mill mounting frame 201. The cleaning device 3 continuously works to clean the surface of the grinding roller, causing the adhered materials to fall off and avoiding any impact on the grinding roller. The cleaning device 3 includes a cleaning mounting frame 301. At the end of the cleaning mounting frame 301, a cleaning component 303 is installed and rotatably connected thereto. The cleaning component 303 is located above one side of the grinding roller and extends along the axis direction of the grinding roller. The cleaning component 303 is inclined and fits the surface of the grinding roller. A driving device 302 is installed on the side wall of the cleaning mounting frame 301 to control the rotation of the cleaning component 303. During the rotation of the cleaning component 303, it can continuously clean the surface of the grinding roller. Under the action of friction, a force is applied to the adhered materials to achieve a continuous and efficient cleaning process. Moreover, ventilation openings 3034 are provided on the surface of the cleaning component 303. The ventilation openings 3034 are externally connected to a hot air source. Through the continuous blowing of hot air from the ventilation openings 3034, on the one hand, the hot air flow can generate a force, accelerating the rate and effect of the material falling off the surface of the grinding roller. On the other hand, the hot air flow can dry the materials, reducing the humidity of the materials, further accelerating the detachment efficiency and effect of the materials, and also avoiding the subsequent adhesion of the materials to the surface of the grinding roller, ensuring the normal operation of the overall equipment.

[0028] Specifically, refer to the attached Figure 4 Among them, the cleaning component 303 includes a cleaning rotating shaft 3031. The cleaning rotating shaft 3031 is rotatably connected to the cleaning mounting frame 301. A cleaning mounting cylinder 3032 is fixedly connected to the surface of the cleaning rotating shaft 3031. A cleaning strip 3033 is detachably fixedly connected to the surface of the cleaning mounting cylinder 3032. The end of the cleaning strip 3033 has a certain cleaning interference amount and can fit deeply with the surface of the grinding roller. Through the cleaning strip 3033, deep cleaning of the surface of the grinding roller can be achieved. Moreover, the cleaning strip 3033 is detachably connected to the cleaning mounting cylinder 3032, which is convenient for later maintenance and replacement, reducing the maintenance cost and improving the maintenance efficiency.

[0029] Preferably, the cleaning strips 3033 are arranged in a serpentine distribution along the surface of the cleaning mounting cylinder 3032. A cleaning gap is provided between two adjacent parts of the serpentine cleaning strips 3033. The ventilation openings 3034 are located in the cleaning gap. During the rotation of the serpentine cleaning strips 3033, the cleaning surface moves relative to the surface of the grinding roller, and a tangential and axial combined force can be generated on the surface of the grinding roller, strengthening the cleaning effect of the cleaning strips 3033 on the materials. Moreover, the ventilation openings are located between two adjacent parts of the cleaning strips 3033. During the rotation of the cleaning mounting cylinder 3032, the effect generated by the gas also changes continuously, which can have a stronger effect on the materials and accelerate the detachment of the materials.

[0030] Specifically, refer to the attached Figure 5; wherein the driving device 302 includes a driving installation box, on the surface of the driving installation box is fixedly connected with an electric control device 3021 for controlling the rotation of the cleaning rotating shaft 3031. A gas-blowing assembly 5 is arranged in the cleaning installation box. The gas-blowing assembly 5 can act as a pump and can enhance the efficiency of hot gas pumping as the cleaning assembly is strengthened, so that the cleaning effect is adapted. The gas-blowing assembly 5 includes a gas-blowing baffle 501. An elastic gas-blowing airbag 502 is arranged between the gas-blowing baffle 501 and the inner wall of the driving installation box. The gas-blowing airbag 502 is constantly in an inflated state without external force. A gas-blowing cam 503 is fixedly connected to the surface of the cleaning rotating shaft 3031. The gas-blowing cam 503 is located on one side of the gas-blowing baffle 501 and cooperates with it. The gas-blowing airbag 502 is communicated with two gas-blowing pipes. A first one-way valve is arranged in the gas-blowing pipes. The end of the first gas-blowing pipe is communicated with the air-permeable opening 3034. During the process of controlling the rotation of the cleaning rotating shaft 3031 by the electric control device 3021, the gas-blowing cam 503 can be driven to rotate synchronously. During the rotation of the gas-blowing cam 503, under the synergistic action of the automatic elasticity of the gas-blowing airbag 502, the gas-blowing baffle 501 can be controlled to reciprocate and the gas-blowing airbag 502 can continuously expand and contract intermittently. Under the action of the one-way valve, the two cooperate to complete the pumping of the hot gas source. And as the rotation speed of the cleaning rotating shaft 3031 increases, the cleaning effect of the cleaning strip 3033 is enhanced, and the gas cleaning effect is enhanced synchronously, ensuring the cleanliness and dryness of the surface of the grinding roller.

[0031] When the substances adhered to the surface of the grinding roller are not completely cleaned, it will cause the substances squeezed between the grinding roller and the grinding disc to thicken, and the shaking amplitude of the grinding roller to increase, affecting the normal operation of the grinding roller and the overall equipment. To solve the above problems, the cleaning mounting frame 301 includes a first cleaning mounting part and a second cleaning mounting part. The first cleaning mounting part and the second cleaning mounting part slide linearly relative to each other. An elastic guiding assembly is arranged between the first cleaning part and the second cleaning part, so that they are in a first state, that is, a state of mutual separation, without external force. At this time, the contact force between the cleaning assembly 303 and the grinding roller is not strong, and the working intensity is low, which is suitable for cleaning the surface of the grinding roller with no or less adhered substances. Under the action of external force, the two approach each other and are in a second state, that is, a contracted state. At this time, the distance between the cleaning assembly 303 and the grinding roller becomes smaller, the extrusion force and the cleaning friction force increase, which is suitable for the adaptive cleaning of the state where more substances are adhered to the surface of the grinding roller.

[0032] Among them, a control opening is formed in the inner wall of the first cleaning and installation part. A control piston 3012 is hermetically and slidably connected in the control opening. A control rod 3011 fixedly connected to the control piston 3012 is fixedly arranged on the side wall of the second cleaning and installation part. The control opening communicates with a first control pipeline 3013 and a second control pipeline 3014. A second one-way valve is arranged in the first control pipeline 3013, and an electric control valve is arranged in the second control pipeline 3014. When the electric control valve is in an open state all the time, at this time, gas can freely enter and exit the control opening through the second control pipeline 3014. At this time, under the action of the elastic guiding component, a buffering effect can be achieved between the two. The second cleaning and installation part will vibrate synchronously at a farther position along with the vibration of the grinding roller, remaining within the rated range to ensure the cleaning effect. When the vibration amplitude of the grinding roller increases, the vibration amplitude of the second cleaning and installation part also increases. At this time, the electric control valve is closed, and at this time, gas cannot freely enter and exit the control opening, and the remaining gas will be discharged from the control opening during the vibration process. At this time, the second cleaning and installation part and the cleaning component 303 vibrate slightly at a closer position to complete a more effective cleaning of the grinding roller.

[0033] A material guiding component 4 is further arranged in the vertical mill chamber 101. A first material guiding plate is arranged at the upper end of the material guiding component 4, and a second material guiding plate is arranged at the lower end of the material guiding component 4. Among them, the material guiding component 4 is inclined, and the opening direction of the lower end of the material guiding component 4 faces the edge part of the grinding table. The material cleaned by the cleaning component 303 drops from the first material guiding plate into the material guiding component 4 and is finally discharged from the second material guiding plate. The inclined material guiding component 4 can directly let the material drop to the edge part of the grinding table, and it is located on one side of the grinding roller. At this time, the dried and cleaned material directly drops between the grinding roller and the grinding table to complete subsequent extrusion and powder making. The cleaned material does not need to be dispersed from the middle position, greatly improving the powder making efficiency of the equipment.

[0034] In order to deeply dry the material cleaned on the surface of the grinding roller, the material guiding component 4 includes a material guiding cylinder body 401. An inclined first receiving plate 402 and a second receiving plate 403 are fixedly connected to the inner wall of the material guiding cylinder body 401. The first receiving plate 402 and the second receiving plate 403 are alternately distributed to form a material guiding channel. A heat source, which can be selected as a resistance wire, is installed on the inner wall of the material guiding component 4 to create a dry atmosphere in the material guiding channel. At this time, the material can slide between the inclined first receiving plate 402 and the second receiving plate 403. During the sliding process, on the one hand, the dispersion of the material is completed to avoid its adhesion, and on the other hand, the drying time of the material can be prolonged to avoid re-adhesion to the surface of the grinding roller during subsequent extrusion.

[0035] To enhance the effect of material dispersion, dispersion blades 404 are installed on the inner wall of the bottom end of the material guiding cylinder body 401. A driving assembly is arranged inside the material guiding cylinder body 401 to control the rotation of the dispersion blades 404. When the material drops onto the surface of the dispersion blades 404, the dispersion blades 404 can strike the material during the rotation process, dispersing the material to prevent it from sticking. Moreover, the rotating dispersion blades 404 can generate negative pressure at the top, driving the gas flow and guiding the hot air at the cleaning assembly 303 to flow in a specific direction, enhancing the drying of the material. At the same time, it can also discharge the water vapor inside the material guiding cylinder body 401, ensuring a dry drying atmosphere and improving the drying effect.

[0036] During the working process of the present invention, the material to be processed drops onto the grinding disc. During the rotation of the grinding disc, on the one hand, it can disperse the material and move it towards the grinding roller direction, and on the other hand, it can drive the grinding roller to rotate synchronously during its own rotation. The material is squeezed and ground into powder between the grinding roller and the grinding disc. When the humidity of the ground material is relatively high, part of the material adheres to the surface of the grinding roller, affecting the subsequent grinding of the grinding roller.

[0037] To overcome the above problems, during the rotation of the grinding roller, the cleaning assembly 303 is controlled to rotate by the driving device 302. The cleaning assembly 303 is in contact with the surface of the grinding roller. During the rotation of the cleaning assembly 303, it can clean the surface of the grinding roller. Moreover, cleaning strips 3033 are fixed on the surface of the cleaning installation cylinder 3032. The cleaning strips 3033 are distributed in a snake shape. During the rotation of the snake-shaped distributed cleaning strips 3033, a tangential force can be generated, strengthening the cleaning effect on the surface of the grinding roller. And it can clean the residual debris on the surface of the grinding roller in a specific direction, and finally drop into the material guiding assembly 4 and then fall back to the edge of the grinding disc, realizing the roll pressing process. Hot air is continuously blown out from the surface of the air permeable opening 3034. On the one hand, it can strengthen the cleaning effect on the adhered material, and on the other hand, it can dry the adhered material to prevent it from adhering to the surface of the grinding roller subsequently.

[0038] The material cleaned by the cleaning device 3 drops into the material guiding assembly 4. The material moves directionally in the material guiding channel formed by the first receiving plate 402 and the second receiving plate 403, and can be dried again in a heated environment during the movement process to reduce moisture. Finally, it drops onto the surface of the dispersion blades 404, is scattered by the dispersion blades 404, and is finally exported from the lower end and roll-pressed into powder.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
