Description

Technical Field

[0001] This invention relates to the field of integrated micro-powder grinding equipment, and more particularly to an integrated micro-powder grinding equipment for ultrasonically enhanced fly ash activation. Background Technology

[0002] Fly ash is one of the industrial wastes with the largest discharge volume in my country. If a large amount of fly ash is not treated, it will cause many serious problems. One of the main applications of fly ash is as a concrete admixture. However, raw fly ash has many performance defects, which limits its widespread use in concrete. Therefore, processing fly ash has become an inevitable trend.

[0003] However, the existing integrated fly ash grinding equipment still has the following two shortcomings in use: First, due to the unique physical properties of fly ash, fly ash particles have a porous structure, which makes it easy for the powder particles to be of different sizes during grinding. In order to make the material fully meet the fineness requirements, the grinding time has to be extended. As a result, not only do the product output and quality decrease, but the power consumption also increases significantly. Secondly, current grinding equipment does not perform tiered and layered grinding of fly ash. Since fly ash raw materials may contain large particles, gaps exist between the larger particles during grinding, resulting in incomplete grinding. Summary of the Invention

[0004] This invention relates to an integrated ultrasonic-enhanced fly ash activation micro-grinding device. A filter cover is fixedly installed on the lower end face of the top plate of the tank. The surface of the filter cover has uniformly distributed filter holes. As the material is lifted, it passes through the filter cover. Smaller particles that meet the fineness requirements can pass through the filter holes, while larger particles are intercepted. The intercepted coarse particles then fall back to the bottom of the device under gravity and continue to participate in the grinding process until they reach the required fineness standard, thus achieving efficient material screening and continuous grinding.

[0005] This invention provides an integrated device for ultrasonically enhanced fly ash activation micro-grinding, specifically comprising: a tank; The lower end face of the tank is equipped with three supporting legs in a ring shape, the upper end face of the tank is equipped with a discharge pipe in the middle, the bottom plate of the tank is provided with a circular track groove, and an ultrasonic generator is fixedly installed on the lower end face of the tank. A baffle is located inside the tank. Four connecting blocks are installed in a ring on the outer end face of the baffle. The other end of each connecting block is fixedly connected to the inner end face of the baffle. The first motor is fixedly installed at the middle position of the lower end face of the tank. A rotating roller is fixedly installed at the end of the drive shaft of the first motor. The upper end face of the rotating roller has an inclined structure, and baffles are evenly installed on the outer end face of the rotating roller. The rolling wheel is rotatably connected between two adjacent baffles. There are four sets of rolling wheels, each set containing seven rolling wheels, arranged in a ring structure. The fixing plate is a ring structure and is fixedly installed on the inner end face of the baffle. The inner end surface of the fixing plate has four slots. A conveying pipe is fixedly installed on the outer end surface of the tank. A second motor is fixedly installed on the outer end surface of the conveying pipe, and a drive shaft is connected to the front end face of the second motor.

[0006] Furthermore, six air inlet pipes are installed in a ring shape below the outer end face of the tank, and one-way valves are installed inside the air inlet pipes.

[0007] Furthermore, the outer end face of the rolling wheel has an arc-shaped structure, and the outer end faces of the two sets of rolling wheels at the upper position are evenly equipped with balls, while the outer end faces of the two sets of rolling wheels at the lower position have a smooth structure.

[0008] Furthermore, the outer end of the rolling wheel is engaged in a groove on the surface of the fixed plate, and the outer end of the lower surface of the groove has an inclined structure.

[0009] Furthermore, a filter cover is fixedly installed on the lower end face of the top plate of the tank, and filter holes are evenly opened on the surface of the filter cover.

[0010] Furthermore, a negative pressure pipe is fixedly installed on the outer end face of the discharge pipe, and a negative pressure device is connected to the negative pressure pipe.

[0011] Furthermore, the bottom end face of the rotating roller is inclined, and a fixing ring is fixedly installed on the lower end face of the rotating roller, with the outer end face of the fixing ring flush with the outer end face of the rotating roller.

[0012] Furthermore, a limiting block is welded to the lower end face of the fixing ring, and the limiting block is rotatably connected to the track groove on the bottom plate surface of the tank.

[0013] Furthermore, a guide plate is fixedly installed on the upper end face of the baffle, the inner end face of the guide plate has an inclined structure, and a limit ring is fixedly installed on the lower end face of the guide plate.

[0014] Furthermore, a feed pipe is fixedly installed on the upper end face of the conveying pipe. The feed pipe has a funnel-shaped structure, and blades are welded to the outside of the drive shaft. The blades have a spiral structure, and the outer end face of the blades is in contact with the inner wall of the conveying pipe.

[0015] This invention provides an integrated ultrasonic-enhanced fly ash activation micro-grinding device, which has the following beneficial effects: 1. The feed pipe has a funnel-shaped structure, which helps the fly ash to enter the conveying pipe more smoothly. The blades on the outside of the drive shaft have a spiral structure. Under the pushing action of the blades, the fly ash is gradually conveyed to the inside of the tank along the inner wall of the conveying pipe, thus completing the feeding operation.

[0016] 2. Baffles are evenly installed on the outer end face of the rotating roller. A rolling wheel is rotatably connected between two adjacent baffles. As the rotating roller rotates, the baffles and rolling wheel also move. The fly ash entering the tank is guided by the inclined upper end face of the rotating roller. At the same time, a guide plate is fixedly installed on the upper end face of the baffle. The inner end face of the guide plate has an inclined structure, which can promote the fly ash to enter between the rolling wheel and the groove. The rolling wheel will perform preliminary rolling on the material, thereby realizing the rolling of fly ash.

[0017] 3. The two sets of rolling rollers at the top are evenly equipped with balls on their outer end faces, while the two sets of rolling rollers at the bottom have a smooth outer end face. As the rollers rotate continuously, the rolling rollers will roll continuously in the grooves. The rolling rollers with balls at the top will crush and knead larger particles of material while rolling, making the material particles finer. The rolling rollers with a smooth structure at the bottom will further grind the material mainly through their own weight and the pressure generated by rotation, thereby achieving the grading and crushing of fly ash.

[0018] 4. Six air inlet pipes are installed in a ring shape at the lower part of the outer end face of the tank. One-way valves are installed inside the air inlet pipes. Under the action of the fan, outside air enters the tank through the air inlet pipes. The one-way valves can ensure that air can only enter the tank in one direction. The air entering the tank will form an upward airflow, which will lift the material that has undergone preliminary grinding and ultrasonic strengthening upward and discharge it from the discharge pipe.

[0019] 5. A filter cover is fixedly installed on the lower end face of the top plate of the tank. The surface of the filter cover is evenly provided with filter holes. When the material is lifted up, it will pass through the filter cover. Smaller particles that meet the fineness requirements can pass through the filter holes of the filter cover, while larger particles will be intercepted by the filter cover. The coarse particles intercepted by the filter cover will fall back to the bottom of the device under the action of gravity and continue to participate in the grinding process until they reach the qualified fineness standard, thereby realizing efficient screening and continuous grinding of materials.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. Based on the described 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.

[0025] Example 1: Please refer to Figures 1 to 9 : This invention proposes an integrated device for ultrasonically enhanced fly ash activation micro-grinding, comprising: a tank 1; The lower end face of the tank body 1 is equipped with three support legs 101 in a ring shape. The stability of the tank body 1 can be improved by setting the support legs 101. The discharge pipe 104 is installed in the middle of the upper end face of the tank body 1. The bottom plate surface of the tank body 1 is provided with a circular track groove 103. An ultrasonic generator 8 is fixedly installed on the lower end face of the tank body 1. Baffle 2 is located inside tank 1. Four connecting blocks 201 are installed in a ring on the outer end face of baffle 2. The other end of the connecting block 201 is fixedly connected to the inner end face of baffle 2. The first motor 4 is fixedly installed at the middle position of the lower end face of the tank body 1. A rotating roller 401 is fixedly installed at the end of the drive shaft of the first motor 4. The upper end face of the rotating roller 401 is inclined. Baffles 402 are evenly installed on the outer end face of the rotating roller 401. The rolling roller 5 is rotatably connected between two adjacent baffles 402. There are four sets of rolling rollers 5, with seven rolling rollers 5 in each set. The seven rolling rollers 5 are arranged in a ring structure. The fixing plate 7 is a ring structure. The fixing plate 7 is fixedly installed on the inner end face of the baffle 2. Four slots 701 are opened on the inner end surface of the fixing plate 7. The conveying pipe 9 is fixedly installed on the outer end surface of the tank body 1. The second motor 10 is fixedly installed on the outer end surface of the conveying pipe 9. The front end face of the second motor 10 is connected to the drive shaft 1001.

[0026] Among them, the outer end face of the rolling wheel 5 is arc-shaped, and the two sets of rolling wheels 5 at the upper position are evenly installed with ball bearings 501 on the outer end face, while the two sets of rolling wheels 5 at the lower position have a smooth outer end face, which can crush fly ash in layers.

[0027] The outer end of the rolling wheel 5 is engaged in the groove 701 on the surface of the fixed plate 7. The outer end of the lower surface of the groove 701 has an inclined structure, which helps the powder to move downward.

[0028] A filter cover 105 is fixedly installed on the lower end face of the top plate of the tank body 1. The surface of the filter cover 105 is uniformly provided with filter holes. The filter cover 105 can screen the powder in the gas. The qualified fine powder can pass smoothly through the discharge pipe 104 and be collected as the finished product. The coarse particles intercepted by the filter cover 105 will fall back to the bottom of the device under the action of gravity and continue to participate in the grinding process until they reach the qualified fineness standard, thereby realizing the efficient screening and continuous grinding of materials.

[0029] The bottom end face of the rotating roller 401 is inclined, and a fixing ring 6 is fixedly installed on the lower end face of the rotating roller 401. The outer end face of the fixing ring 6 is flush with the outer end face of the rotating roller 401.

[0030] Among them, the lower end face of the fixed ring 6 is welded with a limiting block 601. The limiting block 601 is rotatably connected in the track groove 103 on the bottom plate surface of the tank body 1. In use, when the first motor 4 drives the rotating roller 401 to rotate, the limiting block 601 below the fixed ring 6 is slidably locked in the track groove 103, which can ensure the stability of the rotating roller 401 during operation.

[0031] Among them, a guide plate 3 is fixedly installed on the upper end face of the baffle 2. The inner end face of the guide plate 3 is inclined. A limit ring 301 is fixedly installed on the lower end face of the guide plate 3. During use, it helps the material to move towards the position of the rolling wheel 5 and the groove 701.

[0032] The upper end face of the conveying pipe 9 is fixedly installed with a feed pipe 901, which has a funnel-shaped structure. The drive shaft 1001 is welded with blades 1002, which have a spiral structure. The outer end face of the blades 1002 is in contact with the inner wall of the conveying pipe 9. In use, fly ash enters the conveying pipe 9 through the feed pipe 901. The funnel-shaped structure of the feed pipe 901 helps the fly ash to enter the conveying pipe 9 more smoothly. Under the pushing action of the spiral blades 1002, the fly ash is gradually transported along the inner wall of the conveying pipe 9 to the inside of the tank 1, completing the feeding operation.

[0033] Example 2, based on Example 1, such as Figures 1-9 As shown, a negative pressure pipe 1041 is fixedly installed on the outer end face of the discharge pipe 104. The negative pressure pipe 1041 is connected to a negative pressure device. Six air inlet pipes 102 are installed in a ring shape below the outer end face of the tank body 1. A one-way valve 1021 is installed inside the air inlet pipe 102.

[0034] By adopting the above scheme, the technical effects are as follows: a gas flow channel is formed between the baffle 2 and the tank 1. A negative pressure pipe 1041 is installed on the surface of the discharge pipe 104. The negative pressure pipe 1041 can be connected to an external fan. After the fan is started, the air at the bottom of the tank 1 will enter the upper part of the tank 1 through the channel between the baffle 2 and the tank 1, and then be discharged through the discharge pipe 104. The powder will be discharged from the discharge pipe 104 together with the gas. A filter cover 105 is installed under the top plate of the tank 1 to ensure that only the fine particles that meet the conditions will enter the discharge pipe 104, while the larger particles will fall to the bottom of the tank 1 for further micronization.

[0035] The working principle of this embodiment: In this invention, the second motor 10 is started, which drives the blades 1002 on the surface of the drive shaft 1001 to rotate. Fly ash enters the conveying pipe 9 through the feed pipe 901, which has a funnel-shaped structure to facilitate smoother entry of the fly ash into the conveying pipe 9. Under the pushing action of the spiral blades 1002, the fly ash is gradually conveyed along the inner wall of the conveying pipe 9 into the tank 1, completing the feeding operation. The first motor 4 is fixedly installed at the middle position of the lower end face of the tank 1. When the first motor 4 is started, it drives the rotating roller 401 to start rotating. Baffles 402 are evenly installed on the outer end face of the rotating roller 401. A rolling wheel 5 is rotatably connected between adjacent baffles 402. As the rotating roller 401 rotates, the baffles 402... The rolling roller 5 also moves accordingly. The fly ash entering the tank 1 is guided by the inclined upper surface of the rotating roller 401. At the same time, a guide plate 3 is fixedly installed on the upper surface of the baffle 2. The inner end surface of the guide plate 3 has an inclined structure, which can promote the fly ash to enter between the rolling roller 5 and the slot 701. The rolling roller 5 will perform preliminary rolling on the material, thereby achieving the rolling of fly ash. After rolling, the powder will enter the lower part of the tank 1. During the rolling process, the outer end surfaces of the two sets of rolling rollers 5 at the upper position are evenly installed with balls 501, and the outer end surfaces of the two sets of rolling rollers 5 at the lower position have a smooth structure. The outer end of the rolling roller 5 is engaged in the slot 701 on the surface of the fixed plate 7. The outer end of the lower surface of the slot 701 has an inclined structure. As the rotating roller 401 continues to rotate, the grinding wheel 5 rolls continuously within the slot 701. The upper grinding wheel 5, equipped with ball bearings 501, crushes and kneads larger particles, refining them. The lower, smooth grinding wheel 5 further grinds the material primarily through its own weight and the pressure generated by rotation. Because the outer end of the lower surface of the slot 701 is inclined, the material experiences both downward and outward forces during grinding by the grinding wheel 5, facilitating its movement downwards into the slot 701. This continuous grinding and refining of the material under the action of the grinding wheel 5 achieves a higher fineness requirement. At this point, the ultrasonic generator 8 begins operation. The ultrasonic generator 8 is fixedly installed... The lower end face of tank 1 emits high-frequency ultrasonic waves. These ultrasonic waves propagate through the material in the form of mechanical waves, accelerating the physical and chemical changes of the material, thereby strengthening and activating it, and improving the activity and reactivity of fly ash. Six air inlet pipes 102 are installed in a ring shape below the outer end face of tank 1. One-way valves 1021 are installed inside the air inlet pipes 102. Outside air enters the interior of tank 1 through the air inlet pipes 102 under the action of a fan. The one-way valves 1021 ensure that air can only enter tank 1 in one direction. The air entering tank 1 will form an upward airflow, lifting the material that has undergone preliminary grinding and ultrasonic strengthening upward. A filter cover 105 is fixedly installed on the lower end face of the top plate of tank 1. The surface of the filter cover 105 is evenly provided with filter holes.As the material is lifted, it passes through a filter hood 105. Smaller particles that meet the fineness requirements can pass through the filter holes of the filter hood 105, while larger particles are intercepted. A discharge pipe 104 is fixedly installed at the middle of the upper end face of the tank 1. A negative pressure pipe 1041 is fixedly installed on the outer end face of the discharge pipe 104. A negative pressure device is connected to the negative pressure pipe 1041. Under the action of the negative pressure device, a negative pressure environment is formed inside the discharge pipe 104, allowing the qualified fine powder that has passed through the filter hood 105 to pass smoothly through the discharge pipe 104 and be collected as the finished product. The coarse particles intercepted by the filter hood 105 fall back to the bottom of the device under gravity and continue to participate in the grinding process until they reach the qualified fineness standard, thus achieving efficient material screening and continuous grinding.
