Description

Technical Field

[0001] This utility model belongs to the field of grinding mill technology, specifically relating to a gypsum particle grinding mill. Background Technology

[0002] Traditional gypsum grinding mills typically employ a multi-motor drive system, with separate motors for crushing, grinding, and auxiliary screening. While this multi-motor drive system achieves basic grinding functions, it has significant drawbacks. First, the use of multiple motors substantially increases equipment procurement costs and energy consumption. Statistics show that compared to single-motor driven equipment, multi-motor driven gypsum grinding mills have higher equipment costs and energy consumption for the same production capacity, which undoubtedly imposes a significant economic burden on long-term industrial production. Second, the multi-motor layout results in complex and bulky equipment structures, occupying a large amount of production space and hindering compact factory layouts and efficient production. For example, in some small and medium-sized gypsum processing enterprises, the excessively large size of the equipment leads to crowded workshop spaces, affecting material transportation and personnel operation, and reducing overall production efficiency.

[0003] Furthermore, sieving is a crucial step in the gypsum grinding process, directly affecting the particle size and purity of the product. However, most existing grinding mills use vibrating screens, where the entire sieving device vibrates except for the support legs, much like a vibrating screen. This causes powder to float in the air and generates significant noise, negatively impacting worker health. On the other hand, existing vibrating screens lack effective cleaning methods. As gypsum powder accumulates on the screen, it gradually clogs the screen holes, reducing sieving efficiency and requiring frequent shutdowns for screen cleaning, further disrupting production continuity. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a gypsum granule grinding mill that solves the problems of existing gypsum granule grinding mills, such as high procurement costs and energy consumption due to multi-motor drive, complex equipment structure and large footprint, low efficiency in the screening process and difficulty in cleaning the screen.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a gypsum granule grinding mill, comprising a casing, a main motor mounted on the top of the casing, a feed inlet at the bottom of the casing, a screen support installed inside the casing, a screen mounted on the top surface of the screen support, a main shaft driven by the main motor, the axis of the main shaft being collinear with the axis of the screen, the main shaft being connected to a crushing roller in a crushing mechanism via a transmission assembly, the crushing roller being rotatably mounted in a guide trough, a slot adapted to install the guide trough being opened on the top of the casing, and a grinding mechanism being connected to the main shaft via a transmission assembly, the grinding mechanism comprising a grinding roller, a striking roller, and a push plate, the grinding mechanism being positioned above the screen.

[0006] The beneficial effects of this utility model are as follows: the use of a single main motor in conjunction with transmission component one and transmission component two realizes the crushing, grinding and beating of gypsum and the beating of the screen, effectively reducing the cost and volume of the device; when the grinding mechanism rotates, it can realize the grinding, spreading and vibrating sieving of gypsum, effectively improving the sieving efficiency.

[0007] In order to enable the main shaft to effectively drive the crushing mechanism through the use of transmission component one;

[0008] As a further improvement to the above technical solution: the transmission assembly includes a worm and a worm wheel. The worm is mounted on the main shaft and meshes with the worm wheel. The worm wheel is mounted on one end of the shaft of one of the crushing rollers, and meshing transmission gears are mounted on the shafts of the two crushing rollers.

[0009] The beneficial effects of this improvement are: during the process of driving the grinding mechanism to rotate, the main shaft also drives the crushing roller to rotate at low speed through the worm gear pair mechanism, thereby crushing the gypsum raw material fed into the feed trough.

[0010] In order to effectively ensure the transmission stability of the gear mechanism in the first transmission component and the crushing mechanism;

[0011] As a further improvement to the above technical solution: the outer cover of the worm and worm wheel is equipped with an isolation cover, the top of the isolation cover is connected to the inner top surface of the machine housing, the main shaft rotates through the bottom of the isolation cover, the side cover of the guide chute is equipped with a protective cover, and the transmission gear is located inside the protective cover.

[0012] The beneficial effects of this improvement are: the isolation cover and protective cover can isolate and protect the gear mechanism, and prevent the gypsum material from contacting the gears, thus preventing gear wear and damage.

[0013] In order to enable the grinding mechanism to rotate along multiple axes by using transmission component two;

[0014] As a further improvement to the above technical solution: the transmission component two includes an outer shell, which is fixed on the main shaft. The bottom end of the main shaft is located inside the outer shell and is fixed with a bevel gear one. The bevel gear one meshes with two bevel gears two. The two bevel gears two are respectively installed on the grinding roller and the striking roller, and both bevel gears two are located inside the outer shell.

[0015] The beneficial effects of this improvement are as follows: when the main shaft drives the outer casing and bevel gear one to rotate synchronously, the outer casing drives the entire grinding mechanism to rotate around the axis of the main shaft, while bevel gear one meshes with and drives bevel gear two, causing the grinding roller and the striking roller to rotate.

[0016] In order to effectively grind plaster;

[0017] As a further improvement to the above technical solution: the curved side surface of the grinding roller is rolled to connect with the top surface of the screen.

[0018] The beneficial effect of this improvement is that the grinding roller can effectively grind the material on the screen during rotation.

[0019] For effective vibration grinding of medicinal powder;

[0020] As a further improvement to the above technical solution: the striking roller includes a rotating shaft, the curved side of the rotating shaft is connected to one end of a plurality of flexible connecting rods, and the other end of the flexible connecting rods is connected to a striking ball.

[0021] The beneficial effects of this improvement are as follows: when the rotating shaft rotates, it drives the striking ball to swing through the flexible connecting rod, so that the striking ball hits the screen, effectively dispersing the gypsum powder that has been ground and pressed onto the screen surface by the grinding roller, allowing the gypsum powder to pass through the screen quickly and shaking out the particles that are blocking the screen holes.

[0022] To further improve the sieving speed of materials;

[0023] As a further improvement to the above technical solution: the bottom surface of the pusher plate is slidably connected to the top surface of the screen.

[0024] The beneficial effects of this improvement are: when the pusher plate rotates, it can spread the powder shaken up by the beating roller evenly on the screen, increasing the contact area between the powder and the screen, thereby improving the screening efficiency.

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0033] Example 1:

[0034] like Figure 1As shown in Figure 5: A gypsum granule grinding mill includes a housing 1, a main motor 2 mounted on the top of the housing 1, a feed inlet 3 at the bottom of the housing 1, a screen support 4 installed inside the housing 1, a screen 5 mounted on the top surface of the screen support 4, a main motor 2 driving a main shaft 6, the axis of the main shaft 6 being collinear with the axis of the screen 5, the main shaft 6 being connected to a crushing roller 83 in a crushing mechanism 8 via a transmission assembly 7, the crushing roller 83 being rotatably mounted in a guide trough 81, a slot for mounting the guide trough 81 being provided on the top of the housing 1, the main shaft 6 being connected to a grinding mechanism 10 via a transmission assembly 9, the grinding mechanism 10 including a grinding roller 101, a striking roller 102 and a push plate 103, the grinding mechanism 10 being positioned above the screen 5; the use of a single main motor 2 in conjunction with the transmission assembly 7 and the transmission assembly 9 achieves the crushing, grinding and striking of gypsum and the screen, effectively reducing the cost and size of the device;When the grinding mechanism 10 rotates, it can grind, spread, and vibrate the gypsum for sieving, effectively improving the sieving efficiency. The transmission component 7 includes a worm gear 71 and a worm wheel 72. The worm gear 71 is mounted on the main shaft 6 and meshes with the worm wheel 72. The worm wheel 72 is mounted on one end of the shaft of one of the crushing rollers 83. The shafts of the two crushing rollers 83 are equipped with meshing transmission gears 84. During the process of driving the grinding mechanism 10 to rotate, the main shaft 6 also drives the crushing rollers 83 to rotate at low speed through the worm gear pair mechanism, thereby crushing the gypsum raw materials fed into the feed trough 81. The worm gear 71 and the worm wheel 72... An isolation cover 73 is installed on the outer side, and the top of the isolation cover 73 is connected to the inner top surface of the housing 1. The main shaft 6 rotates through the bottom of the isolation cover 73. A protective cover 82 is installed on the side cover of the material guide trough 81. The transmission gear 84 is located inside the protective cover 82. The isolation cover 73 and the protective cover 82 can isolate and protect the gear mechanism, preventing the gypsum raw material from contacting the gear and causing wear and damage to the gear. The transmission component 2 9 includes an outer shell 91, which is fixed on the main shaft 6. The bottom end of the main shaft 6 is located inside the outer shell 91 and is fixed with a bevel gear 1 92. The bevel gear 1 92 meshes with two bevel gears 2 93. Two bevel gears 93 are respectively mounted on the grinding roller 101 and the striking roller 102, and both bevel gears 93 are located inside the outer casing 91. When the main shaft 6 drives the outer casing 91 and the bevel gears 92 to rotate synchronously, the outer casing 91 drives the grinding mechanism 10 to rotate around the axis of the main shaft 6. At the same time, the bevel gears 92 mesh with and drive the bevel gears 93, causing the grinding roller 101 and the striking roller 102 to rotate. The curved side of the grinding roller 101 is rolled to the top surface of the screen 5. During the rotation of the grinding roller 101, the material on the screen 5 can be effectively ground. The striking roller 102 includes a rotating shaft 104. The curved side of the screen 5 is connected to one end of multiple flexible connecting rods 105. The other end of each flexible connecting rod 105 is connected to a striking ball 106. When the rotating shaft 104 rotates, the flexible connecting rods 105 drive the striking ball 106 to swing, causing it to strike the screen 5. This effectively disperses the gypsum powder ground and pressed onto the surface of the screen 5 by the grinding roller 101, allowing the gypsum powder to pass through the screen quickly and dislodging particles clogging the screen holes. The bottom surface of the push plate 103 is slidably connected to the top surface of the screen 5. When the push plate 103 rotates, it can spread the powder shaken up by the striking roller 102 evenly on the screen 5, increasing the contact area between the powder and the screen 5, thereby improving the sieving efficiency.

[0035] The working principle of this technical solution is as follows: The gypsum granules to be processed are continuously fed into the equipment through the feed chute 81 at the top of the casing 1. After the main motor 2 starts, it drives the main shaft 6 to rotate at high speed. The worm gear 71 installed on the main shaft 6 rotates accordingly, and through the meshing transmission worm wheel 72, it drives one of the crushing rollers 83 to rotate at low speed. The meshing transmission gears 84 installed on the shafts of the two crushing rollers 83 cause the two crushing rollers 83 to rotate in opposite directions, thus squeezing and shearing the gypsum granules entering the feed chute 81. The crushed gypsum particles fall evenly onto the screen 5 through the opening below the feed chute 81. During this process, the isolation cover 73 and the protective cover 82 effectively isolate the gypsum raw material from the transmission gears, worm gears, and other components, preventing dust from entering and affecting transmission stability and extending the service life of the equipment. While the main shaft 6 drives the crushing mechanism 8, it also drives the grinding mechanism 10 through the transmission component 2 9. The bevel gear 1 92 at the bottom of the main shaft 6 rotates inside the outer casing 91, meshing with two bevel gears 2 93, causing the grinding roller 10 to rotate. The grinding roller 101 and the striking roller 102 rotate, while the outer casing 91 drives the grinding mechanism 10 to rotate around the axis of the main shaft 6. During the rotation, the curved side of the grinding roller 101 is in close contact with the top surface of the screen 5, crushing the gypsum particles falling on the screen 5 and further refining them. At the same time, when the rotating shaft 104 of the striking roller 102 rotates, it drives the striking ball 106 to swing through the flexible connecting rod 105. The striking ball 106 continuously hits the screen 5, producing a vibration effect. This vibration not only crushes the gypsum particles but also... The grinding roller 101 grinds and disperses the gypsum powder that is pressed and compacted on the surface of the screen 5, allowing it to pass through the screen 5 quickly. It can also effectively shake out particles that are clogging the screen holes, keeping the screen 5 unobstructed. When the push plate 103 rotates with the grinding mechanism 10, its bottom surface slides into contact with the top surface of the screen 5, spreading the powder shaken up by the beating roller 102 evenly on the screen 5, increasing the contact area between the powder and the screen 5, and further improving the sieving efficiency. The qualified gypsum powder passes through the screen 5 and is discharged from the discharge port 3 at the bottom of the machine casing 1, entering the subsequent collection process.
