Description

Technical Field

[0001] The invention relates to the technical field of airflow stirring mechanisms, and in particular to a device and process for uniformly mixing multiple materials. Background Art

[0002] Cement is a solid substance that is made of a variety of mixed materials after being mixed and squeezed by a roller press, selected by the front-end, and ground by a mill into a powder. Since adding a certain amount of mineral powder to cement has little or no effect on the quality of cement, and the fineness of the mineral powder is similar to that of cement, adding it before the front-end mill will increase energy consumption and increase the electricity consumption per ton of cement, which is not worth the loss. Uneven addition in the back-end will cause large fluctuations in cement quality. Too much will lead to a long cement retarding time, and too little will increase material costs and affect cement quality.

[0043] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0044] Embodiment 1

[0045] like Figure 1As shown, a device for uniformly mixing multiple materials comprises:

[0046] A ball mill 1, wherein the ball mill 1 is used for grinding cement;

[0047] A water washing mechanism 2, the water washing mechanism 2 is used to wash the mineral powder with water, the water washing mechanism 2 comprises a water tank 21, a hot air circulation dryer 22 and an exhaust assembly arranged in the water tank 21;

[0048] A mixing mechanism 3, which is arranged behind the ball mill 1 and the water washing mechanism 2 and is used to mix cement and mineral powder. The mixing mechanism 3 includes an air mixing component 31 for quickly mixing cement and mineral powder and a collecting component 32 for collecting and outputting the mixed materials;

[0049] The circulating air path 4 is used to connect the ball mill 1, the water washing mechanism 2 and the mixing mechanism 3 to achieve wind circulation.

[0050] In this embodiment, the cement and the mineral powder are efficiently mixed by providing the mixing mechanism 3 and the circulating air path 4, and the wind force is used to achieve full mixing of the materials on the one hand and separation of the materials on the other.

[0051] In detail, the ball mill 1 and the water washing mechanism 2 are used to process the cement and the mineral powder respectively, and the processed cement and the mineral powder are input into the mixing mechanism 3 for mixing, and the air mixing component 31 is used to achieve sufficient mixing of the materials, and the collecting component 32 is used to collect and output the mixed materials. The circulating air path 4 participates in the whole mixing process and circulates the wind power.

[0052] It should be noted that the circulating air path 4 is connected to the washing mechanism 2 and the mixing mechanism 3 respectively, so as to realize the conduction of the air flow, so that the whole system forms a complete air path circulation.

[0053] It is worth mentioning that, through the setting of the mixing mechanism 3, the mixing process of the materials can be carried out continuously, which is conducive to continuous production.

[0054] Further, if Figure 2 As shown, the air mixing assembly 31 includes a mixing bin 316 with an air inlet 311 at the bottom, an air outlet 312 at the top and feed ports on both sides, two groups of mixing rollers 313 arranged at the lower part of the mixing bin 316, multiple groups of arc leaves 314 rotatably connected under the mixing rollers 313, and an air jet component 315 for jetting to lift the material.

[0055] In this embodiment, by providing the mixing roller 313 and the arc-shaped blades 314 , the rotation of the mixing roller 313 and the arc-shaped blades 314 is utilized to achieve rapid mixing of the materials.

[0056] In detail, the materials enter the mixing bin 316 from both sides, are preliminarily mixed by the rotation of the mixing roller 313, and continue to fall onto the arc leaves 314. The arc leaves 314 rotate to further mix the materials under the action of centrifugal force and falling gravity.

[0057] It should be noted that the mixing roller 313 is driven by a reducer at the same time, and a plurality of hinges with special angles are welded on the mixing roller 313. When the material enters the mixing bin 316, the material is flipped up and down and left and right under the action of the rotation of the hinges with special angles.

[0058] It is worth mentioning that under the action of the curved plate, the materials gather towards the middle.

[0059] Further, if Figure 3 , Figure 4 As shown, the jetting member 315 includes a rotating frame 3151 connected to the air inlet 311 of the mixing chamber 316 by a motor, a first fan 3152 arranged at the center of the rotating frame 3151, a plurality of smaller second fans 3153 evenly arranged at the edge of the first fan 3152, the second fans 3153 are rotatably connected to the rotating frame 3151 and rotate regularly through a driving member 3154, and also includes a conical platform 3155 arranged below the second fan 3153, an output port 3156 arranged below the conical platform 3155, and an air inlet pipe 3157 arranged around the conical platform 3155;

[0060] In this embodiment, by setting up the first fan 3152 and the second fan 3153, the material is blown so that the material is mixed more evenly under the action of the wind airflow, and at the same time plays a certain sorting role, such as separating materials with larger particles that cannot be driven by the airflow.

[0061] In detail, the first fan 3152 and the second fan 3153 are started and rotated at the same time under the action of the rotating frame 3151, blowing the materials falling on the arc leaves 314 upward, and cooperating with the swing of the second fan 3153 to achieve full mixing of the materials in the air.

[0062] It should be noted that the first fan 3152 blows air vertically upward to lift the material upward, and the second fan 3153 swings regularly to make the material have a certain inclination angle when entering the air flow area of ​​the first fan 3152.

[0063] It is worth mentioning that, by utilizing the arrangement of the conical platform 3155 , the output port 3156 and the air inlet pipe 3157 , smaller particles of material are lifted up by the airflow, while larger particles of material cannot be blown up and are output from the mixing bin 316 through the output port 3156 .

[0064] Further, if Figure 5 , Figure 6 As shown, the driving member 3154 includes a hinged rod 331 arranged on the outside of the second fan 3153 and slidably connected to the rotating frame 3151, a first gear 332 rotatably connected to the outside of the rotating frame 3151 and driving the hinged rod 331 to swing back and forth through a sliding shaft, and a second gear 333 fixedly connected to the side wall of the air inlet 311 and meshing with the first gear 332.

[0065] In this embodiment, the regular swing of the second fan 3153 is achieved by providing the hinge rod 331 and the first gear 332 .

[0066] In detail, the rotating frame 3151 rotates to make the first gear 332 rotate along the second gear 333. The first gear 332 rotates under the drive of the second gear 333. The sliding shaft set on the first gear 332 drives the hinge rod 331 to slide back and forth, thereby pushing the second fan 3153 to swing back and forth.

[0067] It should be noted that a slider is provided at the portion where the hinge rod 331 contacts the second fan 3153 , and the second fan 3153 swings in coordination with the movement of the hinge rod 331 .

[0068] It is worth mentioning that the setting of the arc-shaped leaves 314 makes the material move toward the air duct area between the first fan 3152 and the second fan 3153 in the middle. Larger material particles cannot be blown up and fall through the first fan 3152 and the second fan 3153, thereby completing the screening of larger particles.

[0069] Further, if Figure 7 As shown, the jet component 315 further includes a third fan 3158 disposed below the feed port of the mixing bin 316 and a fourth fan 3159 disposed at the air outlet 312 .

[0070] In this embodiment, by providing the third fan 3158 and the fourth fan 3159, the material is guided so that the material can flow along the airflow direction.

[0071] In detail, the third fan 3158 is arranged below the feed ports on both sides, and the material enters the mixing bin 316 from the feed port. Under the blowing of the third fan 3158, the material is sprayed toward the mixing roller 313, so as to accelerate the mixing of the material. The fourth fan 3159 is arranged to make the airflow in the mixing bin 316 move from bottom to top. On the one hand, it matches the first fan 3152 to realize the upward lifting of the material. On the other hand, it extracts the gas in the mixing bin 316 to keep the air pressure in the mixing bin 316 constant.

[0072] It should be noted that the airflow direction of the third fan 3158 blows toward the mixing roller 313, and the fourth fan 3159 extracts the gas in the mixing bin 316 and outputs it to the outside of the mixing bin 316. The fourth fan 3159 can output tiny particles in the lifted material to the mixing bin 316 along the airflow, so that only material particles of suitable size are left in the mixing bin 316.

[0073] It is worth mentioning that, through the provision of the fourth fan 3159, the internal air pressure of the mixing bin 316 is kept stable, which is beneficial to the subsequent output of materials.

[0074] Further, if Figure 8 As shown, the collecting assembly 32 includes a sedimentation plate 321 which is arranged in the middle of the mixing bin 316 and is connected to the side wall of the mixing bin 316 through a motor, the sedimentation plate 321 is provided with an air hole in the center, a plurality of ribs are evenly arranged axially above the sedimentation plate 321, a material trough 322 for outputting materials is provided on the side wall of the mixing bin 316, an inclined plate 323 is provided in the material trough 322, the inclined plate 323 is slidably connected to the mixing bin 316 and an electric cylinder is provided below the upper part.

[0075] In this embodiment, by setting the sedimentation plate 321 and the inclined plate 323, the lifted material can fall evenly to the upper surface of the sedimentation plate 321. With the rotation of the sedimentation plate 321, under the action of centrifugal force, the material on the surface of the sedimentation plate 321 enters the material trough 322 and is output from the mixing bin 316.

[0076] In detail, the material is lifted upward by the action of the first fan 3152 and the second fan 3153, and the material falls onto the surface of the settling plate 321 after passing through the wind holes. The settling plate 321 rotates to make the material on the surface slide into the material troughs 322 around it and fall onto the inclined plate 323. The inclined plate 323 is vibrated by the action of the electric cylinder. The vibration of the inclined plate 323 and a smaller airflow are used to make the material on the upper part of the inclined plate 323 fall downward and be output from the mixing bin 316 through the discharge port on the side wall of the mixing bin 316.

[0077] It should be noted that since the hot air circulation dryer continuously inputs air flow into the system, the system needs to use the discharge port as the air flow output port. However, due to the setting of the fourth fan 3159, the air flow is directed straight upward, avoiding a large air flow from driving the material to be ejected from the discharge port, and preventing the material from being lifted up during the output process, causing material loss and dust.

[0078] It is worth mentioning that, through the setting of the settling plate 321, the materials can evenly fall onto the settling plate 321, so that the cement and the mineral powder are fully mixed to achieve stable output.

[0079] Further, if Fig. 9As shown, the exhaust assembly is arranged in the middle of the water tank 21 and includes a hollow shaft 231 rotatably connected to the middle of the water tank 21, fan blades 232 fixedly connected to the bottom of the hollow shaft 231, and multiple groups of jet pipes 233 arranged at the top of the hollow shaft 231.

[0080] In this embodiment, the hollow rotating shaft 231 and the air injection pipe 233 are provided to allow the air flow extracted from the mixing chamber 316 to flow into the water tank 21, thereby promoting the mineral powder water washing step.

[0081] In detail, air flows into the hollow shaft 231, and the airflow drives the fan blades 232 and the hollow shaft 231 to rotate, and at the same time enters the interior of the hollow shaft 231, and is output through the jet pipe 233. The end of the jet pipe 233 is set in the cleaning liquid in the water tank 21. The gas overflows and forms bubbles that escape upward. With the rotation of the hollow shaft 231, the mineral powder in the water can be fully mixed and cleaned.

[0082] It should be noted that the top of the hollow shaft 231 extends out of the liquid surface of the cleaning liquid, and the gas injection pipe 233 extends into the cleaning liquid to release gas.

[0083] It is worth mentioning that by extending the jet pipe 233 into the cleaning liquid, the tiny cement powder carried in the gas is retained in the water, thereby achieving gas purification.

[0084] Further, if Fig. 9 As shown, the water tank 21 is further provided with a filter 211 for separating the mineral powder from the mortar and a conveying device 212 for conveying the mineral powder to the hot air circulation dryer 22 .

[0085] In this embodiment, the filter 211 and the conveying device 212 are provided to filter the mineral powder, and the filtered mineral powder is filtered out of the mortar and input into the hot air circulation dryer 22 for drying.

[0086] In detail, the mineral powder is cleaned in the water tank 21, and the mineral powder in the mortar is filtered out by the filter 211. A microporous filter can be used for the filter 211. The filtered mineral powder is transported to the hot air circulation dryer 22 for drying by the conveying device 212. The conveying device 212 can be a conveyor belt.

[0087] It should be noted that the filter 211 can be used to filter out impurities in the mortar including particles carried in the air flow.

[0088] Further, if Fig.10 As shown, the circulating air path 4 includes a cooling pipe 41 disposed outside the ball mill 1 and a drying box 42 connected to the cooling pipe 41;

[0089] The circulating air path 4 uses the hot air blown out by the hot air circulating dryer 22 as the wind input source. The hot air dries the mineral powder and then connects to the cooling pipe 41, passes through the drying box 42, and is input into the mixing bin 316 from the air inlet 311 for material mixing, and then is connected to the hollow rotating shaft 231 through the air outlet 312, and is released into the water tank 21. The upper part of the water tank 21 is connected to the cooling pipe 41, and the airflow enters the cooling pipe 41 again for recycling.

[0090] In this embodiment, by providing a cooling pipe 41 and a drying box 42, the airflow input into the mixing chamber 316 is dried, thereby supplementing the wind circulation system and allowing the airflow to circulate in the device.

[0091] In detail, the hot air circulation dryer 22 is the wind input source of the system. The hot air carries moisture after drying the mineral powder, and converges with the airflow released from the water tank 21, passes through the cooling pipe 41, and the cooling pipe 41 is beneficial to cooling the ball mill 1. Then, the water vapor in the airflow is removed through the drying box 42, and then input into the mixing bin 316 from the first fan 3152 and the third fan 3158 for material mixing. Through the fourth fan 3159, the airflow carrying the particles flows to the water tank 21, assists in washing the mineral powder, and the gas escapes from the water surface and enters the cooling pipe 41 through the pipeline again.

[0092] It is worth mentioning that by setting up the circulating air path 4 and using the hot air circulating dryer 22 as the wind output source, it is possible to avoid the input of impurities during the wind input process, causing material pollution. On the other hand, it reduces the generation of dust, which is conducive to environmental protection and safety of production.

[0096] Step 1, grinding and washing step: the cement raw material is conveyed to the ball mill 1 for grinding and the mineral powder is conveyed to the water tank 21 for washing. The washed mineral powder is conveyed to the hot air circulation dryer 22 through the filter 211 for drying.
