Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, specifically a mixing device for preparing concrete using industrial waste residue. Background Technology

[0002] Fly ash is a fine ash collected from the flue gas after coal combustion. It is the main solid waste discharged by coal-fired power plants. With the development of the power industry, the amount of fly ash discharged by coal-fired power plants has been increasing year by year, making it one of the industrial waste residues with the largest discharge volume in my country.

[0003] In existing technologies, certain additives can be added to concrete during mixing to increase its hardness. Among these additives, concrete slurry containing fly ash can have its hardness significantly improved after air drying.

[0004] However, directly adding fly ash in batches during the preparation process can easily lead to clumping, making it difficult to mix evenly. The fly ash content may be too high or too low in some areas, resulting in uneven mechanical properties of the finished concrete and thus failing to effectively improve the hardness of the concrete. In view of this, we propose a mixing device for preparing concrete using industrial waste residue. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for preparing concrete from industrial waste residue, comprising a mixing chamber, a drive motor fixedly connected to the top of the mixing chamber, a stirring rod fixedly connected to the output end of the drive motor, and a dispensing component provided on the inner wall of the mixing chamber, the dispensing component comprising: A guide ring is provided, with a sliding seat fixedly connected to its bottom. The sliding seat is slidably connected to a slider. A sieve basket is fixedly connected to the end face of the slider. An elliptical groove is provided on the inner bottom surface of the sieve basket. An elastic telescopic rod is fixedly connected to the side wall of the sieve basket. A cloth brush is fixedly connected to the side wall of the stirring rod, a scraper is fixedly connected to the side wall of the stirring rod, and a guide block is fixedly connected to the side wall of the stirring rod.

[0007] Preferably, the mixing silo has a feed inlet fixedly connected to its side wall, a discharge port opened at the top of the mixing silo, and a discharge pipe fixedly connected to its bottom, through which fly ash is discharged into the mixing silo.

[0008] Preferably, the guide ring is located directly below the inlet, the cross-section of the guide ring is triangular, and the inclined surface of the triangle is located on the side away from the inner wall of the mixing chamber.

[0009] Preferably, one end of the elastic telescopic rod is fixedly connected to the sieve basket, and the other end of the elastic telescopic rod is fixedly connected to the fixing block, which is fixedly connected to the bottom end face of the guide ring.

[0010] Preferably, the powder brush is movably connected to the inclined surface of the guide ring, the scraper is movably connected to the inner bottom surface of the sieve basket, and the guide block is movably connected to the inner wall of the elliptical groove.

[0011] Preferably, a baffle is fixedly connected to the side wall of the stirring rod, and the baffle is movably connected to the inner bottom surface of the sieve basket.

[0013] Compared with the prior art, this utility model provides a mixing device for preparing concrete from industrial waste residue, which has the following beneficial effects: 1. This mixing device for preparing concrete using industrial waste residue, through a set feeding component, uses a brush to slowly sweep fly ash along an annular guide ring into a screen basket, controlling the feeding speed of fly ash. The fly ash is dispersed before being swept into the screen basket, which is beneficial for further uniform processing. The reciprocating motion of the screen basket gives the feeding process a lateral diffusion effect, which helps the fly ash to spread rapidly in the concrete slurry, reducing the waste of raw materials caused by insufficient reaction due to agglomeration. The active scraping action of the scraper can push or move the ash material accumulated on the surface of the screen basket in real time, making it continuously loose and moving, enhancing the dispersibility of fly ash, and preventing material blockage and accumulation.

[0014] 2.

[0017] like Figures 1-6 As shown, this utility model provides a technical solution: a mixing device for preparing concrete from industrial waste residue, including a mixing chamber 1, a drive motor 4 fixedly connected to the top of the mixing chamber 1, a stirring rod 5 fixedly connected to the output end of the drive motor 4, and a dispensing component 6 provided on the inner wall of the mixing chamber 1. The dispensing component 6 includes a guide ring 601, a sliding seat 602, a slider 603, a sieve basket 604, an elliptical groove 605, a powder cloth brush 606, a scraper 607, a guide block 608, and an elastic telescopic rod 609.

[0018] In one embodiment of this utility model, a guide ring 601 is fixedly connected to the inner wall of the mixing chamber 1. The guide ring 601 is located directly below the inlet 3. The cross-section of the guide ring 601 is triangular, with the inclined surface of the triangle located on the side away from the inner wall of the mixing chamber 1. A sliding seat 602 is fixedly connected to the bottom of the guide ring 601. The sliding seat 602 is slidably connected to the slider 603. A sieve basket 604 is fixedly connected to the end face of the slider 603. An elliptical groove 605 is opened on the inner bottom surface of the sieve basket 604. An elastic telescopic rod 609 is fixedly connected to the side wall of the sieve basket 604. One end of the elastic telescopic rod 609 is fixedly connected to the sieve basket 604, and the other end of the elastic telescopic rod 609 is fixedly connected to a fixing block. The fixing block is fixedly connected to the bottom end face of the guide ring 601. The elastic telescopic rod 609 pushes the sieve basket 604 to reset through elasticity.

[0019] The powder brush 606 is fixedly connected to the side wall of the stirring rod 5. The powder brush 606 is movably connected to the inclined surface of the guide ring 601. The scraper 607 is fixedly connected to the side wall of the stirring rod 5. The scraper 607 is movably connected to the inner bottom surface of the sieve basket 604. The guide block 608 is fixedly connected to the side wall of the stirring rod 5. The guide block 608 is movably connected to the inner wall of the elliptical groove 605.

[0020] A feed inlet 2 is fixedly connected to the side wall of the mixing chamber 1, a discharge port 3 is opened at the top of the mixing chamber 1, and a discharge pipe is fixedly connected to the bottom of the mixing chamber 1. Fly ash is fed into the mixing chamber 1 through the discharge port 3. A baffle 7 is fixedly connected to the side wall of the stirring rod 5. The baffle 7 is movably connected to the inner bottom surface of the screen basket 604. The baffle 7 covers the elliptical groove 605, thereby preventing fly ash from falling into the material below through the elliptical groove 605.

[0021] Fly ash is fed into the inlet 3, and the drive motor 4 drives the stirring rod 5 to rotate, which in turn drives the powder brush 606 to rotate. The powder brush 606 slowly sweeps the ash material along the annular guide ring 601 into the screen basket 604, controlling the feeding speed of the fly ash. The fly ash is dispersed before being swept into the screen basket 604, which is conducive to further uniform processing. The rotation of the stirring rod 5 drives the guide block 608 to rotate, which in turn pushes the elliptical groove 605, causing the screen basket 604 and the slider 603 to move laterally back and forth along the sliding seat 602. This allows the ash material to fall evenly through the screen holes into the concrete below, achieving uniform distribution. The falling process has a lateral diffusion effect, which helps the fly ash to spread rapidly in the concrete slurry and reduces the waste of raw materials caused by insufficient reaction due to agglomeration.

[0022] The rotation of the stirring rod 5 drives the scraper 607 to rotate. The scraper 607 forcibly pushes the fly ash material on the top of the screen basket 604. The active scraping action of the scraper 607 can push or move the fly ash material accumulated on the surface of the screen basket 604 in real time, so that it continues to move loosely, enhances the dispersion of fly ash, prevents material blockage and accumulation, and helps fly ash to fully contact the screen holes, so that fly ash can fall into the concrete continuously and evenly.

[0023] In addition, a cleaning brush 8 is fixedly connected to the side wall of the stirring rod 5. The cleaning brush 8 is movably connected to the bottom of the sieve basket 604. As the stirring rod 5 rotates, the cleaning brush 8 continuously brushes the bottom of the sieve, which can remove the attached dust or impurities in real time, push the powder blocked in the sieve holes upward out of the sieve holes, keep the sieve holes unobstructed, avoid obstruction of material flow, realize automatic self-cleaning, and reduce manual maintenance.

[0024] In this invention, fly ash is fed into the inlet 3, and the drive motor 4 drives the stirring rod 5 to rotate, which in turn drives the cloth brush 606 to rotate. The cloth brush 606 slowly sweeps the fly ash along the annular guide ring 601 into the screen basket 604, controlling the feeding speed of the fly ash. The fly ash is dispersed before being swept into the screen basket 604, which is beneficial for subsequent uniform processing. The screen basket 604 and the slider 603 move laterally back and forth along the sliding seat 602, so that the fly ash falls evenly through the screen holes into the concrete below, achieving uniform distribution. This gives the feeding process a lateral diffusion effect, which helps the fly ash to spread rapidly in the concrete slurry. The active scraping action of the scraper 607 can push or move the fly ash accumulated on the surface of the screen basket 604 in real time, making it continuously loose and moving, enhancing the dispersibility of the fly ash.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
