Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flash mills, in particular to a flash mill with a medium recycling structure. BACKGROUND

[0002] A flash mill is a fine grinding device widely used in mining, building materials, chemical industry and other industries. It realizes superfine crushing of materials by rotating a stirring rod at high speed in a tank filled with wear-resistant medium balls (such as steel balls, ceramic balls, etc.) to make the medium balls collide and rub with the materials. In the operation process of such equipment, the wear-resistant medium balls are one of the core elements to ensure grinding efficiency and product quality.

[0003] However, under the condition of long-term continuous high-intensity work, the medium balls will inevitably be worn, resulting in gradual reduction of their particle size and change of their spherical shape. These small medium balls caused by wear will gradually settle at the bottom of the mill, which not only cannot effectively participate in the grinding process, reducing the overall grinding efficiency, but also may increase the energy consumption of the equipment, and even affect the particle size distribution of the discharged slurry. At present, the main way to deal with such problems is still to stop regularly, clean the bottom of the tank by manual method, and screen and supplement the medium. This method not only has high labor intensity and causes production interruption, but more importantly, manual screening is difficult to accurately distinguish between medium that can still be used and medium that is completely invalid, often causing medium with value to be discarded together, resulting in continuous medium waste and high production cost.

Detailed Implementation

[0026] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0027] Please see Figure 1 and Figure 2This invention provides a flash mill with a media recovery structure, comprising a tank 1, a cover 2, locking components 3, a drive body 4, a stirring rod 5, a bottom cover 6, a recovery structure 7, support legs 8, a feed inlet 9, a discharge outlet 10, a drain outlet 11, and an inclined seat 12. The top of the tank 1 is provided with a cover 2, which is locked and fixed by three equally spaced locking components 3. The cover 2 and the locking components 3 ensure the sealing of the tank 1, preventing slurry leakage, and at the same time, facilitate opening for maintenance or cleaning. Media balls are provided inside the tank 1. The drive body 4 is installed on the top of the cover 2. The bottom output end of the drive body 4 is connected to the stirring rod 5. The drive body 4 provides power to drive the stirring rod 5 to rotate. The stirring rod 5 rotates through the middle of the cover 2, and the bottom end of the stirring rod 5 contacts the bottom side of the tank 1. The rotation of the stirring rod 5 directly acts on the media balls and slurry at the bottom of the tank 1, ensuring grinding efficiency. At the same time, the contact between the stirring rod 5 and the bottom of the tank 1 helps to prevent the media balls and slurry from depositing.

[0028] A bottom cover 6 is fixedly connected to the bottom of the tank body 1. A recycling structure 7 is embedded inside the bottom cover 6. The bottom cover 6 accommodates the recycling structure 7, providing space for media recycling and allowing the recycling process to take place inside the equipment, reducing external intervention. Three support legs 8 are evenly distributed at the bottom of the bottom cover 6 to support the entire equipment and prevent movement or tilting during operation. The upper left and right sides of the tank body 1 are respectively provided with a feed inlet 9 and a discharge outlet 10. The feed inlet 9 is used to input slurry, and the discharge outlet 10 is used to output the ground product, realizing a continuous production process. A drain outlet 11 is opened on the bottom rear side of the tank body 1 to discharge waste or wastewater after cleaning, keeping the inside of the equipment clean and preventing blockage. An annular inclined seat 12 is provided at the connection between the inner side wall and the bottom of the tank body 1 to guide the media balls and slurry to the bottom, making it easy for the recycling structure 7 to collect the worn media balls.

[0029] Please see Figure 2 and Figure 3 The present invention provides a flash mill with a media recovery structure. The recovery structure 7 includes a hopper cover 71 fixed inside the bottom cover 6. An electromagnetic valve 72 is provided on the top middle side of the hopper cover 71, and a guide frame 73 is installed at the bottom of the electromagnetic valve 72. A cleaning and feeding assembly 74 is provided below the guide frame 73. The electromagnetic valve 72 is used to control the inflow of media balls, and the guide frame 73 guides the media balls into the cleaning and feeding assembly 74 to realize automated control. The cleaning and feeding assembly 74 cleans the media balls and performs single-time small-volume feeding.

[0030] The cleaning feeding component 74 is inserted into the bottom right side of the discharge component 75 to ensure that the cleaned media balls can smoothly enter the discharge component 75 for further processing; the discharge component 75 is fixed inside the lower side of the hopper cover 71 to provide a stable output path; a hollow groove is opened on the bottom rear side of the hopper cover 71 for sewage discharge, allowing waste to be discharged, keeping the inside of the recycling structure 7 clean, and preventing accumulation.

[0031] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6 The present invention provides a flash mill with a media recovery structure. The cleaning feeding component 74 includes a support base 741 whose bottom is fixed to the discharge component 75. A column 742 is fixedly connected to the front top of the support base 741. A first motor 743 is locked and fixed to the upper right of the column 742. A gear column 744 is connected to the output shaft on the left side of the first motor 743. The first motor 743 is used as a power source to drive the gear column 744 to rotate.

[0032] The toothed portion of the toothed column 744 is respectively engaged with the first toothed disc 745 and the second toothed disc 746. The toothed column 744 transmits the rotational motion of the first motor 743 to the two toothed discs to realize power transmission. The first toothed disc 745 is located to the right of the second toothed disc 746, and the rear middle side of the second toothed disc 746 is rotatably connected to the slide 747. The slide 747 slides laterally on the top left side of the support seat 741, and a push-swing component 748 is connected to the left side of the slide 747. The bottom of the push-swing component 748 is fastened to the support seat 741. The push-swing component 748 drives the slide 747 to reciprocate left and right on the support seat 741, thereby improving the cleaning effect on the medium ball by changing the position between the two toothed discs.

[0033] A guide channel 749 is fixedly installed through the bottom right side of the support base 741. The guide channel 749 is located below the inner side of the first toothed disc 745 and the second toothed disc 746. The bottom of the guide channel 749 is inserted into the discharge assembly 75 to guide the cleaned media balls into the discharge assembly 75 and ensure smooth transmission. The rear middle side of the first toothed disc 745 is rotatably connected to the support base 741. A first brush roller 7410 is coaxially rotatable at the rear of the first toothed disc 745, and a second brush roller 7411 is coaxially rotatable at the rear of the second toothed disc 746. The two brush rollers rotate in opposite directions through the two toothed discs to cooperate in removing the adhering substances on the media balls.

[0034] The first toothed disc 745 and the second toothed disc 746 have the same structure and size, and the first brush roller 7410 and the second brush roller 7411 have the same structure and size. The first brush roller 7410 and the second brush roller 7411 are located at the same horizontal height, and the top of the first brush roller 7410 and the second brush roller 7411 are located below the bottom side of the guide frame 73. The standardized design simplifies manufacturing and maintenance, and the position of the brush rollers ensures effective contact with the media ball for thorough cleaning. The support seat 741 has a groove on the top left side, and the slide seat 747 has a protrusion on the bottom middle side. The protrusion is inserted into the groove and slides inside. The mating structure of the groove and the protrusion provides precise sliding guidance to ensure that the slide seat 747 moves smoothly.

[0035] The push-swing component 748 includes a vertical plate 7481 whose bottom is fixed to the discharge component 75. A second motor 7482 is locked to the left front part of the vertical plate 7481. The top output shaft of the second motor 7482 is connected to a turntable 7483. A connecting rod 7484 rotates eccentrically on the top of the turntable 7483, and the other end of the connecting rod 7484 is rotatably connected to a push rod 7485. The second motor 7482 serves as a power source, driving the turntable 7483 to convert the rotational motion into the reciprocating motion of the connecting rod, thereby driving the push rod 7485 to reciprocate laterally. The push rod 7485 slides through the support block 7486, and the right end of the push rod 7485 is connected to the slide block 747. The rear part of the support block 7486 is fastened to the vertical plate 7481. The support block 7486 guides the movement of the push rod 7485, ensuring that the push rod 7485 accurately pushes the slide block 747 to perform reciprocating lateral displacement.

[0036] Please see Figure 3 and Figure 7 The present invention provides a flash mill with a media recovery structure. The discharge assembly 75 includes a silo 751 fixed inside the bottom side of the bottom cover 6. A third motor 752 is locked and fixed inside the right side of the silo 751. The output shaft of the third motor 752 on the left side is connected to an auger 753, and the auger 753 is rotatably connected inside the silo 751. The third motor 752 provides power to drive the auger 753 to transport the media and realize automatic discharge.

[0037] An inlet 754 is located on the top right side of the silo 751, and the interior of the inlet 754 is connected to the cleaning and unloading assembly 74. The inlet 754 receives the cleaned media balls, ensuring a seamless connection. A qualified bead tube 756 is located on the bottom left side of the silo 751, and at least seven defective bead tubes 755 are arranged to the right of the qualified bead tube 756. The qualified bead tube 756 collects media balls in good condition for reuse, and the defective bead tubes 755 collect damaged media balls for cleaning, achieving classified recycling and reducing the loss of media balls. The bottoms of both the defective bead tubes 755 and the qualified bead tubes 756 extend downwards to penetrate the bottom cover 6, so as to allow the classified media balls to be discharged from the equipment, which facilitates collection and processing and saves costs.

[0038] The flash mill with a media recovery structure of the present invention operates on the following principle when it is necessary to recover the media balls inside the flash mill whose particle size has decreased due to wear after the flash mill has been running for a period of time:

[0039] First, start the recycling structure 7 and open the electromagnetic valve 72 located at the top of the hood 71. The medium ball and slurry mixture that are guided and gathered at the bottom of the tank 1 by the inclined seat 12 fall into the guide frame 73 under the action of gravity and enter the cleaning and feeding assembly 74 below it.

[0040] Second, after the media ball enters the cleaning and feeding assembly 74, the first motor 743 starts and drives the toothed column 744 to rotate, which in turn drives the first toothed disc 745 and the second toothed disc 746 meshing with it to rotate. This ultimately causes the coaxially connected first brush roller 7410 and second brush roller 7411 to rotate in opposite directions, allowing the media ball to undergo coordinated cleaning by the first brush roller 7410 and the second brush roller 7411. This counter-rotating motion effectively removes slurry residue adhering to the surface of the media ball. Simultaneously, the second motor 7482 in the pushing and swinging component 748 starts, driving... The turntable 7483 rotates, and the push rod 7485 moves laterally and reciprocally through the eccentrically set connecting rod 7484. The push rod 7485 pushes the slide 747 to slide stably left and right under the guidance of the groove of the support seat 741. The reciprocating movement of the slide 747 causes the second toothed disc 746 and the second brush roller 7411 connected to it to periodically approach and move away from the first brush roller 7410. This dynamically changing gap not only enhances the cleaning effect, but also prevents the media balls from clogging, ensuring that the cleaned media balls can fall smoothly into the discharge assembly 75 through the guide channel 749.

[0041] Third, the cleaned media balls enter the silo 751 of the discharge assembly 75 through the guide channel 749. At this time, the third motor 752 is started to drive the auger 753 to rotate. The blades of the auger 753 continuously convey the media balls that have entered the silo 751 to the left. During this conveying process, media balls with different degrees of wear will be naturally classified according to the differences in gravity and geometric size in a series of outlets at the bottom of the silo 751: the severely worn media balls with smaller particle size will fall and be collected from the defective bead tube 755 arranged on the right; while the good media balls with larger particle size will be conveyed to a position further to the left by the auger 753 and finally discharged from the qualified bead tube 756, so as to realize the automatic separation and collection of worn media and usable media.

[0042] Fourth, the media balls discharged through the defective bead tube 755 and the qualified bead tube 756 are finally collected separately; the severely damaged media balls can be centrally cleaned and scrapped, while the media balls in good condition can be directly recycled and put back into the flash mill for reuse.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
