[0001] The invention belongs to the technical field of ball mills, and in particular relates to a ball mill discharging device and a method for producing fire retardant coatings. Background Art

[0002] In the production process of fire retardant coatings, ball mills, as one of the key equipment, undertake the important task of finely grinding the coating raw materials; however, traditional ball mill discharge equipment has exposed a series of problems in practical applications, which directly affect the production efficiency and product quality of fire retardant coatings;

[0003] 1. Problems with traditional ball mill discharge equipment

[0004] 1. Poor discharge and blockage:

[0005] In the process of discharging, traditional ball mills often experience poor discharging or even blockage due to material viscosity and uneven particle size. This not only affects the continuity of the production line, but also increases the maintenance burden of operators.

[0006] 2. Grinding efficiency and uniformity:

[0007] During the rotation of the grinding balls in the grinding cylinder, the grinding efficiency is often low due to uneven distribution and insufficient power transmission, and the uniformity of the paint raw materials after grinding is poor; direct recycling affects the quality stability and application scope of the fire retardant coating;

[0031] The present invention also provides a ball mill discharging method for producing fire retardant coatings, comprising:

[0032] Step 1: Raw material grinding: The paint raw material enters the feeding barrel through the feeding port, and then flows into the grinding barrel installed between the bearing seats; the third motor is started, and the grinding barrel is driven to rotate through the meshing action of the driving gear and the driven gear ring; the grinding balls in the grinding barrel grind the paint raw material due to the friction and impact force generated by the rotation until the desired effect is achieved;

[0033] Step 2: Efficient discharge: After grinding, the coating material enters the discharge cylinder connected to the grinding cylinder; at this time, the second motor starts to drive the conveying auger to rotate, effectively pushing the material to move in the specified direction, ensuring that the material is discharged smoothly into the grading shell, improving the discharge efficiency and preventing blockage;

[0035] Step 4: Grading, screening and cleaning: The scattered paint flows to the inclined grading screen under the guidance of the guide plate for further screening; at the same time, the electric telescopic rod drives the cleaning brush to slide on the grading screen through the receiving plate to remove the attached paint and ensure the smooth flow of the screen; larger paint blocks or impurities gather on the side with a lower slope of the screen for subsequent processing;

[0036] Step 5: Centralized cleaning and final discharge: The operator slides the sealed side plate up and down to expose the grading channel, and conducts centralized cleaning and discharge of larger paint blocks or impurities; finally, the paint raw materials screened by the grading screen are discharged from the equipment through the discharge channel at the bottom of the grading shell, completing the entire processing process.

[0037] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0038] Firstly, this device achieves efficient and uniform grinding effect. At the same time, with the cooperation of the conveying auger, it ensures that the ground paint raw materials can be discharged from the grinding cylinder smoothly and efficiently, thereby effectively avoiding the problem of material blockage during the grinding and discharging process, thereby ensuring the continuity and stability of the production line.

[0039] Second: The paint raw materials entering the grading shell of this device are effectively dispersed under the rotation of the grading plate, successfully avoiding the accumulation phenomenon, thereby improving the smoothness of the feeding process. At the same time, the grading plate not only promotes the dispersion of the paint, but also the guide plate below it guides the dispersed paint to the inclined grading screen, further realizing the fine screening of the paint. This ingenious design not only significantly improves the screening efficiency, but also ensures that the paint raw materials can be evenly processed.

[0040] Third: This device is designed with a convenient cleaning and efficient maintenance mechanism, which can easily clean the screen and promptly and effectively remove the paint attached to the screen, thereby effectively preventing the screen from being blocked. In addition, by sliding the sealing side panels up and down, the operator can flexibly open the grading channel to facilitate the centralized cleaning and discharge of larger paint blocks or impurities, which not only significantly extends the service life of the equipment, but also greatly improves the stability and reliability of the overall operation.

[0056] A grading shell 5 is arranged at the bottom of the discharge barrel 4, and the grading shell 5 is connected to the discharge barrel 4;

[0057] A connecting shaft 6 is arranged at the upper part of the inner cavity of the grading shell 5, the connecting shaft 6 is connected to the grading shell 5 through a bearing, and a plurality of grading plates 7 are distributed in an annular manner on the outer circumference of the connecting shaft 6, and the plurality of grading plates 7 are arranged at equal distances;

[0063] A discharge passage 14 communicating with the inner cavity of the grading shell 5 is formed through the bottom of the grading shell 5 .

[0064] It should be noted that, since the traditional ball mill discharge equipment is prone to blockage, has low grinding efficiency and poor uniformity, and is difficult to clean and maintain, these problems together lead to a decrease in the continuity and stability of the production line, a shortened equipment life, and a decrease in the overall operational reliability and stability. This solution achieves efficient and uniform grinding effects, ensuring the fine processing of paint raw materials; secondly, with the help of the smooth discharge mechanism of the conveying auger 15, the blockage of materials during the grinding and discharge process is effectively avoided, ensuring the continuity and stability of the production line; the paint raw materials entering the grading shell 5 are evenly dispersed under the rotation of the grading plate 7, avoiding accumulation, improving the smoothness of material discharge, and further improving the processing quality through fine screening; finally, the convenient cleaning and efficient maintenance mechanism can promptly remove the paint on the screen to prevent blockage, and the operator can flexibly open the grading channel 17 for centralized cleaning, which not only extends the life of the equipment, but also greatly improves the overall operational stability and reliability.

[0065] Specifically, in this embodiment, the present solution mainly comprises a group of bearing seats 1 arranged in parallel, a grinding cylinder 2 is installed between two bearing seats 1, and a plurality of grinding balls 3 are filled inside; when the equipment is started, the grinding cylinder 2 starts to rotate, and the friction and impact force between the grinding balls 3 are used to grind the coating raw materials;

[0066] At one end of the grinding cylinder 2, a feeding structure is provided for continuously feeding the coating raw materials to be ground into the grinding cylinder 2; the raw materials are fully mixed with the grinding balls 3 in the grinding cylinder 2 and subjected to grinding action;

[0067] After grinding, the coating material first enters the discharge barrel 4 connected to the grinding barrel 2; then, the raw material enters the grading shell 5 through the discharge barrel 4; at the upper position of the inner cavity of the grading shell 5, a connecting shaft 6 is provided, which is connected to the grading shell 5 through a bearing, and a plurality of equidistantly arranged grading plates 7 are annularly distributed on its outer circumference. When the first motor 8 is started, the connecting shaft 6 drives the grading plates 7 to rotate, and this process enables the coating material falling on the grading plates 7 to be effectively dispersed, which not only has a good breaking effect, but also can effectively prevent the coating material from accumulating during the material discharge process;

[0068] The graded paint raw materials fall onto the grading screen 9; the grading screen 9 is arranged at an angle to facilitate the sliding of the paint raw materials and further grading; a mounting shell 10 is arranged at an outer position on the side of the grading screen 9 with a higher inclination slope; an electric telescopic rod 11 is arranged in the mounting shell 10, and a receiving plate 12 is connected to the output end of the electric telescopic rod 11; a cleaning brush 13 is arranged on the side of the receiving plate 12 away from the electric telescopic end, and the inclination slope of the cleaning brush 13 is adapted to the inclination slope of the grading screen 9; when it is necessary to clean the grading screen 9, the electric telescopic rod 11 is extended and retracted, and the receiving plate 12 drives the cleaning brush 13 to slide on the grading screen 9 to remove the paint attached to the grading screen 9, so that larger paint or impurities fall to the side of the grading screen 9 with a lower inclination slope, thereby ensuring the smooth flow of the grading screen 9;

[0069] Finally, the coating material screened by the grading screen 9 is discharged from the equipment through the discharge channel 14 at the bottom of the grading shell 5, completing the entire discharge process.

[0070] In a further preferred embodiment of the present invention, Figure 5 As shown, a conveying auger 15 is installed in the discharge barrel 4 through a bearing, a second motor 16 is provided on the end side of the discharge barrel 4 , and an output end of the second motor 16 is fixedly connected with an end key of the conveying auger 15 .

[0071] In this embodiment, when the second motor 16 is started, it drives the conveying auger 15 to rotate, thereby effectively pushing the material in the discharge barrel 4 to move in a specified direction, ensuring that the material can be discharged smoothly from the discharge barrel 4. This design not only improves the discharge efficiency, but also helps prevent the material from being blocked during the discharge process.

[0072] In a further preferred embodiment of the present invention, Figure 3As shown, a grading channel 17 is formed through the inner wall of the grading shell 5 adjacent to the grading screen 9 at a lower slope, and a sealing side plate 18 is slidably fitted to the grading shell 5 at an outer position of the grading channel 17 .

[0073] In this embodiment, after cleaning by the cleaning brush 13, larger paint blocks or impurities will be intercepted by the grading screen 9 and slide along the grading screen 9 to the side with a lower slope. At this time, the operator can slide the sealing side plate 18 up and down to expose the grading channel 17, so as to flexibly realize the timely cleaning and discharge of these larger paint blocks or impurities.

[0074] In a further preferred embodiment of the present invention, Figure 6 As shown, a guide plate 19 is provided in the inner cavity of the grading shell 5 at the upper position of the grading channel 17 , and the guide plate 19 is arranged in the opposite direction to the grading screen 9 .

[0075] In this embodiment, by providing the guide plate 19, the scattered paint can be effectively guided to flow toward the grading screen 9, ensuring that the paint is evenly distributed on the screen for grading treatment.

[0076] In a further preferred embodiment of the present invention, Figure 2 As shown, the feeding structure includes:

[0077] A material loading cylinder 20 is disposed at the other end of the grinding cylinder 2, and the material loading cylinder 20 is connected to the grinding cylinder 2;

[0078] A feeding port 21 communicating with the inner cavity of the upper barrel 20 is disposed at the top thereof.

[0079] In this embodiment, the coating raw material is fed into the upper barrel 20 through the feeding port 21, and flows into the grinding barrel 2 through the upper barrel 20 for subsequent grinding processing.

[0081] In this embodiment, when the driving gear 25 is driven to rotate, it will drive the driven gear ring 23 and the annular gear cover 22 connected thereto and the grinding cylinder 2 to rotate together through the meshing relationship. Such rotation action enables the material in the grinding cylinder 2 to be evenly ground, thereby achieving the desired grinding effect.

[0082] In a further preferred embodiment of the present invention, Figure 1As shown, a third motor 26 is also included, and the output end of the third motor 26 is key-connected and fixed to the shaft end of the driving gear 25 through a reducer 27.

Due to the meshing action between the driving gear 25 and the driven gear ring 23, the driven gear ring 23 is driven to rotate accordingly. The rotation of the driven gear ring 23 drives the grinding cylinder 2 connected thereto to rotate together, thereby achieving the purpose of grinding the material in the cylinder.

[0084] Working principle: When the device is used, the coating raw materials are first fed into the upper barrel 20 through the feeding port 21; these raw materials then flow into the grinding barrel 2 through the upper barrel 20, and the grinding barrel 2 is installed between the two bearing seats 1. The third motor 26 is started to drive the driving gear 25 to start rotating; due to the meshing action between the driving gear 25 and the driven gear ring 23, the driven gear ring 23 is driven to rotate accordingly; the rotation of the driven gear ring 23 drives the grinding barrel 2 connected thereto to rotate together, and a plurality of grinding balls 3 are filled inside; when the grinding barrel 2 starts to rotate, the friction and impact force between the grinding balls 3 grind the coating raw materials until the expected grinding effect is achieved;

[0085] After grinding, the coating material enters the discharge barrel 4 connected to the grinding barrel 2; at this time, the second motor 16 is started to drive the conveying auger 15 to rotate; the rotation of the conveying auger 15 effectively pushes the material in the discharge barrel 4 to move in the specified direction, ensuring that the material can be smoothly discharged from the discharge barrel 4 to the classification shell 5; such a design not only improves the efficiency of discharge, but also helps to prevent the material from being blocked during the discharge process;

[0086] The raw materials enter the grading shell 5 through the discharge barrel 4; a connecting shaft 6 is provided at the upper position of the inner cavity of the grading shell 5, which is connected to the grading shell 5 through a bearing; a plurality of grading plates 7 arranged at equal intervals are distributed in an annular manner on the outer circumference of the connecting shaft 6; when the first motor 8 is started, the connecting shaft 6 drives the grading plates 7 to rotate, so that the paint falling on the grading plates 7 can be effectively dispersed; this process not only has a good dispersing effect, but also can effectively prevent the paint from accumulating during the material discharge process;

[0087] A guide plate 19 is provided below the grading material plate 7, which can effectively guide the scattered paint to flow to the grading screen 9; the grading screen 9 is inclined to facilitate the sliding of the paint raw materials and further screening; a mounting shell 10 is provided at the outer position of the side with a higher inclination slope of the grading screen 9; an electric telescopic rod 11 is provided in the mounting shell 10, and a receiving plate 12 is connected to the output end thereof; a cleaning brush 13 is provided on the side of the receiving plate 12 away from the electric telescopic end, and the inclination slope of the cleaning brush 13 is adapted to the inclination slope of the grading screen 9;

[0088] When the grading screen 9 needs to be cleaned, the electric telescopic rod 11 is extended and retracted, and the receiving plate 12 drives the cleaning brush 13 to slide on the grading screen 9 to remove the paint attached to the grading screen 9; so that larger paint or impurities fall to the side of the grading screen 9 with a lower slope; when larger paint and impurities need to be centrally processed, the operator can flexibly expose the grading channel 17 by sliding the sealing side plate 18 up and down, so as to realize the timely cleaning and discharge of these larger paint blocks or impurities;

[0089] Finally, the coating material screened by the grading screen 9 is discharged from the equipment through the discharge channel 14 at the bottom of the grading shell 5, completing the entire discharge process.
