Description

Technical Field

[0001] This utility model relates to the field of mineral processing technology, and in particular to a bentonite crushing particle size distribution device. Background Technology

[0002] Bentonite is a hydrous aluminum silicate mineral containing small amounts of alkali metals and alkaline earth metals. Its main mineral component is montmorillonite, with a content of 85% to 90%. Some properties of bentonite are determined by montmorillonite. It is insoluble in water and organic solvents, has a specific gravity of 2.4 to 2.8, and a melting point of 1330 to 1430℃. Bentonite has strong hygroscopicity and can absorb water equivalent to 8 to 20 times its own volume and swell to 30 times its own volume. In aqueous media, it can disperse as a colloidal suspension and has certain viscosity, thixotropy, and lubricity. When mixed with mud and sand, it has plasticity and binding properties, and has strong cation exchange capacity and adsorption capacity.

[0003] In existing technologies, traditional equipment is not flexible in adjusting the crushing particle size when crushing bentonite: it requires replacing hammers or screens of fixed size to adjust the particle size, which requires stopping the machine for disassembly and assembly, and is inefficient. In addition, the screening aperture of traditional equipment is fixed and cannot be adjusted in real time according to the collection needs.

[0004] To address this, a bentonite particle size distribution device is proposed. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bentonite crushing particle size distribution device, comprising a support base, a collection groove on the inner side of the support base, a support arm fixedly connected to the rear side of the top of the support base, a crushing barrel fixedly connected to the bottom of the support arm, a feeding port on the top of the crushing barrel, a particle size adjustment mechanism movably connected to the inner side of the crushing barrel, and a filter hole adjustment mechanism movably connected to both the bottom of the crushing barrel and the top of the support base;

[0007] The particle size adjustment mechanism includes a motor rotating rod movably connected inside the crushing barrel. A support plate is fixedly connected to the outer side of the motor rotating rod, and a bearing rod is slidably connected to the inner side of the support plate. A crushing hammer is rotatably connected to the outer side of the bearing rod. A linkage column is fixedly connected to the right side of the bearing rod, and a drive assembly is movably connected to the right side of the linkage column. The drive assembly is movably connected to the right side of the motor rotating rod.

[0008] Preferably, the filter hole adjustment mechanism includes a sliding guide rail fixedly connected to the top of the support base, a sliding arm slidably connected to the top of the sliding guide rail, a cover filter plate fixedly connected to the front side of the sliding arm, the cover filter plate being disposed at the bottom of the crushing barrel and at the top of the collection tank.

[0009] Preferably, a first servo motor is fixedly connected to the front side of the crushing barrel, a drive tooth is fixedly connected to the output end of the first servo motor, a linkage tooth plate is movably connected to the top of the drive tooth, and the linkage tooth plate is fixedly connected to the front side of the shield filter plate.

[0010] Preferably, a support block is fixedly connected to the right side of the front of the crushing barrel, a telescopic rod is fixedly connected to the right side of the linkage tooth plate, the telescopic rod is fixedly connected to the left side of the support block, and a tension spring is fixedly connected to the outer side of the telescopic rod.

[0011] Preferably, the drive assembly includes a second servo motor fixedly connected to the right side of the motor rotor, a first pulley fixedly connected to the output end of the second servo motor, a linkage belt movably connected to the outer side of the first pulley, and a second pulley movably connected to the inner side of the linkage belt.

[0012] Preferably, a hollow rotating column is fixedly connected to the left side of the second pulley, the hollow rotating column is movably connected to the right side of the inner side of the crushing barrel, the hollow rotating column is set on the outer side of the motor rotating rod, a guide plate is fixedly connected to the left side of the hollow rotating column, an arc groove is opened on the inner side of the guide plate, and the linkage column is movably connected to the inner side of the arc groove.

[0013] Preferably, both the crushing barrel and the filter plate have screening grooves on their inner sides.

[0014] Preferably, the rear side of the support base is rotatably connected to a movable door.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application solves the problem of inflexible particle size adjustment in traditional bentonite crushing equipment by setting a particle size adjustment mechanism. In the past, adjusting the particle size of the equipment was troublesome, requiring machine shutdown, disassembly, and replacement of hammers or screens of fixed size, which was very inefficient. Now, it is not so troublesome. By starting the second servo motor, the hollow rotating column can drive the guide plate to rotate. The arc groove squeezes the linkage column, causing the outer distance of the breaker hammer to change accordingly. In this way, when the motor rotating rod is started, the distance and range of the breaker hammer can be flexibly adjusted, easily realizing the adjustment of the crushing particle size. There is no need to stop the machine to replace parts throughout the process. The operation is convenient and efficient, greatly improving the convenience and efficiency of bentonite crushing operations.

[0017] 2. This application solves the problem of inflexible adjustment of screening aperture in traditional equipment by setting up a filter aperture adjustment mechanism. In the past, the screen aperture of the equipment was fixed. If you wanted to change the specification, you had to stop the machine and disassemble the screen, which was particularly troublesome. It was also impossible to adjust according to real-time collection needs. By installing a semi-cylindrical shield filter plate between the collection tank and the crushing tank, it is like a sliding "baffle". When the aperture needs to be adjusted, the first servo motor is started, which makes the drive tooth rotate. Through the meshing linkage tooth plate, the shield filter plate slides left and right. When sliding, the shield filter plate will block the screening tank at the bottom of the crushing tank. The more it blocks, the smaller the aperture, and the less it blocks, the larger the aperture, realizing "changing the aperture as needed". Moreover, when it is adjusted to the limit position, the drive tooth just rotates to the toothless side. At this time, the tensioned telescopic rod and tension spring will automatically push back, allowing the filter plate to return to its original position. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A bentonite crushing particle size distribution device includes a support base 1, a collection trough 2 on the inner side of the support base 1, a support arm 3 fixedly connected to the rear side of the top of the support base 1, a crushing barrel 4 fixedly connected to the bottom of the support arm 3, a feeding port 5 on the top of the crushing barrel 4, a particle size adjustment mechanism 6 movably connected to the inner side of the crushing barrel 4, and a filter hole adjustment mechanism 7 movably connected to both the bottom of the crushing barrel 4 and the top of the support base 1.

[0027] The particle size adjustment mechanism 6 includes a motor rotating rod 61 movably connected inside the crushing barrel. A support plate 62 is fixedly connected to the outside of the motor rotating rod 61. A bearing rod 63 is slidably connected to the inside of the support plate 62. A crushing hammer 64 is rotatably connected to the outside of the bearing rod 63. A linkage column 65 is fixedly connected to the right side of the bearing rod 63. A drive assembly 66 is movably connected to the right side of the linkage column 65. The drive assembly 66 is movably connected to the right side of the motor rotating rod 61.

[0028] In this embodiment: Before carrying out the bentonite crushing work, the crushing particle size can be adjusted according to the state of the bentonite or the specific needs of the crushing process. With the help of the drive component 66, multiple sets of bearing rods 63 and the crusher hammers 64 installed on them can be driven to slide together in a direction away from the center of the support plate 62, so that the outer extension distance of the crusher hammers 64 increases. In this way, when the adjusting motor rod 61 is started, the distance and range of the crusher hammers 64 thrown out by the centrifugal force generated by the rotation will change, thereby realizing the adjustment of the crushing particle size.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the filter hole adjustment mechanism 7 includes a sliding guide rail 71 fixedly connected to the top of the support base 1. A sliding arm 72 is slidably connected to the top of the sliding guide rail 71. A cover filter plate 73 is fixedly connected to the front side of the sliding arm 72. The cover filter plate 73 is set at the bottom of the crushing barrel 4 and at the top of the collection tank 2.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 5As shown, a first servo motor 74 is fixedly connected to the front side of the crushing barrel 4. A drive tooth 75 is fixedly connected to the output end of the first servo motor 74. A linkage tooth plate 76 is movably connected to the top of the drive tooth 75. The linkage tooth plate 76 is fixedly connected to the front side of the shield filter plate 73.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, a support block 77 is fixedly connected to the right side of the front of the crushing barrel 4, and a telescopic rod 78 is fixedly connected to the right side of the linkage tooth plate 76. The telescopic rod 78 is fixedly connected to the left side of the support block 77, and a tension spring 79 is fixedly connected to the outside of the telescopic rod 78.

[0032] In this embodiment: a semi-cylindrical shielding filter plate 73 is provided between the collection tank 2 and the crushing tank 4. The shielding filter plate 73 has a screening groove 8 with the same diameter as the crushing tank 4 and fits snugly. When the diameter needs to be adjusted, the first servo motor 74 is started, causing the drive tooth 75 at the output end of the first servo motor 74 to rotate. When the toothed surface of the drive tooth 75 meshes with the linkage tooth plate 76, it will drive the linkage tooth plate 76, causing the shielding filter plate 73 to slide to one side. During the sliding process, the shielding filter plate 73 will contact the screening groove 8 at the bottom of the crushing tank 4. The opening of the screening tank 8 is adjusted from large to small by blocking it. When the linkage tooth plate 76 is adjusted to the extreme, that is, when the screening tank 8 is completely blocked, the drive tooth 75 just rotates to the toothless surface position. Because when the linkage tooth plate 76 slid to one side, it would tighten the telescopic rod 78 and the outer tension spring 79 between it and the outer wall support block 77 of the support base 1 on the other side. Therefore, after the toothless surface of the drive tooth 75 is connected to the linkage tooth plate 76, the counter-thrust force generated by the telescopic rod 78 and the outer tension spring 79 will drive the shield filter plate 73 to reset.

[0033] Specifically, such as Figure 3 , Figure 4 As shown, the drive assembly 66 includes a second servo motor 66a fixedly connected to the right side of the motor rotor 61. The output end of the second servo motor 66a is fixedly connected to a first pulley 66b. The outer side of the first pulley 66b is movably connected to a linkage belt 66c, and the inner side of the linkage belt 66c is movably connected to a second pulley 66d.

[0034] Specifically, such as Figure 3 , Figure 4 As shown, a hollow rotating column 66e is fixedly connected to the left side of the second pulley 66d. The hollow rotating column 66e is movably connected to the right side of the inner side of the crushing barrel 4. The hollow rotating column 66e is set on the outside of the motor rotating rod 61. A guide plate 66f is fixedly connected to the left side of the hollow rotating column 66e. An arc groove 66g is opened on the inner side of the guide plate 66f. The linkage column 65 is movably connected to the inner side of the arc groove 66g.

[0035] In this embodiment: by activating the second servo motor 66a outside the motor rotor 61, the first pulley 66b at the output end of the second servo motor 66a rotates. When the first pulley 66b rotates, the power is transmitted in the same direction to the second pulley 66d at the other end through the linkage belt 66c. The second pulley 66d is equipped with a hollow rotating column 66e on its outer side. This hollow rotating column 66e extends into the inside of the crushing barrel 4 and is fitted around the outside of the main shaft of the motor rotor 61, but the two are not completely fitted together. Therefore, the rotation of the motor rotor 61 will not affect the hollow rotating column. When the hollow rotating column 66e rotates, it will drive the guide plate 66f inside the crushing barrel 4 to rotate together. The guide plate 66f has multiple arc-shaped grooves 66g on its inner side. During the rotation, the arc-shaped grooves 66g will squeeze the linkage column 65 inside and guide the linkage column 65 along the arc-shaped grooves 66g. Since the linkage column 65 is set on the outside of the bearing rod 63 that carries the breaker hammer 64, in this way, multiple sets of bearing rods 63 and the breaker hammer 64 on them can be driven to slide together away from the center of the support plate 62.

[0036] Specifically, such as Figure 5 As shown, screening grooves 8 are provided on the inner sides of both the crushing barrel 4 and the shielding filter plate 73.

[0037] Specifically, such as Figure 2 As shown, a movable door 9 is rotatably connected to the rear side of the support base 1.

[0038] In this embodiment: the crushed material can be screened and collected through the screening tank 8, and the material inside the collection tank 2 can be collected through the movable door 9.

[0039] Working Principle: Before the bentonite crushing operation, the particle size can be adjusted according to the state of the bentonite or the crushing requirements. The second servo motor 66a, located outside the motor rotor 61, is activated, causing the first pulley 66b at the output end of the second servo motor 66a to rotate. When the first pulley 66b rotates, it drives the second pulley 66d at the other end in the same direction via the linkage belt 66c. A perforated rotating column 66e is located outside the second pulley 66d, extending into the interior of the crushing barrel 4. The perforated rotating column 66e is sleeved on the outside of the main shaft of the motor rotor 61, but not completely fitted. Therefore, the rotation of the motor does not affect the perforated rotating column. When the perforated rotating column 66e rotates… The rotation of the guide plate 66f inside the crushing barrel 4 will drive the guide plate 66f to rotate. Multiple arc-shaped grooves 66g are formed on the inner side of the guide plate 66f. During its rotation, the arc-shaped grooves 66g will compress the linkage column 65 inside and guide the linkage column 65 along the arc-shaped grooves 66g. The linkage column 65 is located on the outer side of the support rod 63 that carries the breaker hammer 64. Therefore, in this way, multiple sets of support rods 63 and their supporting breaker hammers 64 can be simultaneously linked to slide away from the center of the support plate 62, increasing the outer extension distance of the breaker hammer 64. This allows the distance and range of the breaker hammer 64 thrown out by the centrifugal force of rotation when the adjusting motor rod 61 is started, thereby achieving the adjustment of the crushing particle size. After adjustment, bentonite is poured out through the feeding port 5, and the motor rotor 61 is started to perform crushing operations inside the crushing barrel 4. Next, the aperture of the screening trough 8 at the bottom of the crushing barrel 4 can be adjusted according to the crushing and collection requirements. A semi-cylindrical shielding filter plate 73 is installed between the collection trough 2 and the crushing barrel 4, and the shielding filter plate 73 has screening troughs 8 with the same aperture as the crushing barrel 4 that fit snugly. When the aperture needs to be adjusted, the first servo motor 74 is started, causing the drive tooth 75 at the output end of the first servo motor 74 to rotate. When the tooth surface of the drive tooth 75 meshes with the linkage tooth plate 76, the linkage tooth plate 76 is activated, causing the shielding filter plate 73 to slide to one side. In this sliding path, the shielding filter plate 73 blocks the screening groove 8 at the bottom of the crushing barrel 4, causing it to adjust from large to small. When the linkage toothed plate 76 is adjusted to the extreme, that is, the screening groove 8 is completely blocked, the drive residual tooth 75 rotates to the toothless surface. At this time, because the linkage toothed plate 76 previously tightened the telescopic rod 78 and its outer tension spring 79 between itself and the outer wall support block 77 of the support base 1 on the other side when it slid to one side, after the connection is broken, the telescopic rod 78 and its outer tension spring 79 will generate a counter-pushing force to drive the shielding filter plate 73 to reset. In summary, the screening conditions are adjusted according to the collection needs. Finally, the material inside the collection groove 2 is collected through the movable door 9, and the overall crushing operation is completed.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
