Description

Technical Field

[0001] The utility model relates to the technical field of crushing devices, in particular to a crushing device for calcium-based bentonite. Background Technique

[0002] Bentonite is a non-metallic mineral mainly composed of montmorillonite. The montmorillonite structure is a 2:1 type crystal structure composed of two silicon-oxygen tetrahedrons sandwiching a layer of aluminum-oxygen octahedrons. Due to the presence of certain cations in the layered structure formed by montmorillonite unit cells, such as Cu, Mg, Na, K, etc. When the interlayer cation is Na+, it is called sodium-based bentonite; when the interlayer cation is Ca2+, it is called calcium-based bentonite; when the interlayer cation is H+, it is called hydrogen-based bentonite, etc. And bentonite plays an important role in various industrial and environmental applications due to its special structure and adsorption properties. After being mined from the original ore, bentonite often needs to be crushed for processing and production for different purposes.

[0003] Existing bentonite crushing devices generally only have the function of preliminary crushing, which can only crush relatively large lumps of bentonite after mining into relatively small bentonite blocks, and then transport them to subsequent equipment for grinding and processing, thus reducing the use effect of the device. At the same time, due to the strong adsorption property of bentonite itself, when grinding bentonite, when the moisture content in bentonite is relatively high, it is easy to cause the phenomenon of caking in the grinding equipment, which will not only reduce the grinding effect of bentonite, but also may cause damage to the device.

[0004] Therefore, it is necessary to provide a new crushing device for calcium-based bentonite to solve the above technical problems. Content of the Utility Model

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0026] See also Figures 1 to 5 The embodiment of the utility model provides a calcium-based bentonite crushing device, and the calcium-based bentonite crushing device includes: a support frame 1.

[0027] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 A crushing component 2 for initially crushing bentonite is provided on the top of the support frame 1, and a material guide assembly 3 is provided below the crushing component 2; the material guide assembly 3 includes a material guide box 31, and a plurality of inclined and staggered heating plates 32 are provided inside the material guide box 31 through a rotating shaft, a baffle 311 is provided above the connection portion between the inside of the material guide box 31 and the heating plate 32, a spring 33 is provided between the material guide box 31 and the heating plate 32, the top end of the spring 33 is connected to the bottom of the heating plate 32, and the bottom end of the spring 33 is connected to the inner wall of the material guide box 31.

[0028] It should be noted that: through the setting of the material guiding component 3, after the crushing component 2 completes the preliminary crushing of bentonite, during the process of guiding the crushed bentonite, the bentonite can be dried, which can make the effect more excellent when the bentonite is ground into powder for the second time later, and reduce the phenomenon that the bentonite is sticky and caked due to excessive humidity, affecting the grinding;

[0029] And through the setting of the spring 33, the impact force when the bentonite falls and the vibration force generated when the crushing component 2 works can make the spring 33 drive the heating plate 32 to swing to a certain extent, so that the crushed bentonite can fall more smoothly;

[0030] And through the setting of the baffle 311, the baffle 311 can block the upper part of the connection between the heating plate 32 and the material guiding box 31, thereby reducing the phenomenon that the bentonite scatters on the connection part and causing blockage of the connection part.

[0031] In the embodiment of the present utility model, please refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 5 , a movable feeding hopper 4 is provided below the material guiding box 31, and a grinding hopper 41 and a grinding cylinder 5 are provided below the feeding hopper 4. A flexible connection cover 42 is provided at the top of the feeding hopper 4, a top frame 43 is provided at the top of the flexible connection cover 42, two fixedly connected transfer frames 7 are provided outside the feeding hopper 4, the top of the transfer frame 7 is slidably inserted into the top frame 43, and a rotatably connected lead screw 71 is provided at the top of one side transfer frame 7, and the outer wall of the lead screw 71 is threadedly connected with the top frame 43.

[0032] It should be noted that: through the movable installation of the grinding hopper 41, during use, the lead screw 71 can be rotated to drive the transfer frame 7 to move, and the moving transfer frame 7 can drive the feeding hopper 4 connected to the bottom to move synchronously, so that the feeding hopper 4 can drive the grinding hopper 41 below to move, adjusting the gap between the grinding hopper 41 and the grinding cylinder 5, and thus adjusting the fineness of the ground powder later. Therefore, the device can grind bentonite in multiple specifications according to needs, thereby improving the use effect of the device;

[0033] And by integrating crushing and grinding, the integration effect of the device can be improved. During later use, bentonite blocks can be directly made into bentonite powder without the need for secondary processing of transportation, making the use effect of the device more excellent;

[0034] And by providing a flexible connection cover 42 between the feeding hopper 4 and the top frame 43, the flexible connection cover 42 can move synchronously when the position of the feeding hopper 4 is adjusted, avoiding hindrance to the adjustment of the feeding hopper 4 and making the adjustment of the feeding hopper 4 more convenient.

[0035] In an embodiment of the present utility model, please refer to Figure 3 and Figure 5 , a grinding motor 51 is provided at the top of the grinding cylinder 5. An installation frame 52 is provided at the top of the grinding motor 51, and the installation frame 52 is fixedly installed in the top frame 43. A screw conveyor 6 is connected below the grinding hopper 41. A guiding frame 411 is arranged at the discharging end of the grinding hopper 41. A sliding connection inserting rod 53 is inserted inside the guiding frame 411, and the top end of the inserting rod 53 is fixedly connected to the bottom end of the grinding cylinder 5.

[0036] It should be noted that: by fixedly connecting the grinding motor 51 and the top frame 43 through the installation frame 52, the grinding motor 51 and the grinding cylinder 5 can be supported, so that the grinding motor 51 can stably drive the grinding cylinder 5 to rotate later to grind the preliminarily crushed bentonite.

[0037] And through the arrangement of the screw conveyor 6, when the grinding hopper 41 and the grinding cylinder 5 complete the grinding of the bentonite, the working screw conveyor 6 can convey and discharge the ground bentonite outwards.

[0038] Moreover, through the sliding connection between the inserting rod 53 and the guiding frame 411, the sliding frame can improve the stability of the bottom end of the grinding cylinder 5 during rotation by horizontally limiting the inserting rod 53.

[0039] In an embodiment of the present utility model, please refer to Figure 3 , Figure 4 and Figure 5 , connecting frames 34 are provided at both the top and bottom ends of the material guiding box 31. The upper connecting frame 34 is connected to the bottom of the crushing component 2 by bolts. The bottom of the lower connecting frame 34 abuts against the top of the top frame 43. A plurality of fixedly connected convex rods 431 are provided at the top of the top frame 43. The top ends of the convex rods 431 penetrate through the lower connecting frame 34 and are fixedly connected by nuts.

[0040] It should be noted that: by connecting the convex rods 431 with the top frame 43 and the connecting frame 34 by nuts, the installation of components such as the discharging hopper 4 can be completed. During later use, it can make it more convenient for the staff to disassemble the discharging hopper 4, make it more convenient for the staff to overhaul the grinding components, and at the same time, when there is no need to grind the bentonite, the preliminarily crushed bentonite can be directly collected. Therefore, the use range of this device can be improved.

[0041] The working principle of the crushing device for calcium-based bentonite provided by the present utility model is as follows:

[0042] In the later stage of using this device, the staff can first control the rotation of the lead screw 71 according to the required specifications of the bentonite powder. The rotating lead screw 71 can move inside the top frame 43 through the threaded structure. During the movement of the lead screw 71, the transfer frame 7 can drive the feeding hopper 4 and the grinding hopper 41 below it to move. By controlling the movement of the grinding hopper 41, the gap between the grinding hopper 41 and the grinding cylinder 5 can be adjusted, and then the specifications of the powder ground by the two in the later stage can be realized.

[0043] Then, the required bentonite blocks can be added into the crushing component 2, and the crushing cylinder in the crushing component 2 can be controlled to work, so as to realize the crushing of the bentonite. The crushed bentonite can move downward by gravity into the feeding component 3. At this time, the spring 33 in the feeding component 3 can drive the heating plate 32 to vibrate due to the impact force when the crushed bentonite falls and the vibration force generated when the crushing component 2 works. At the same time, since the heating plates 32 are distributed in an inclined and staggered manner, the falling path of the bentonite inside the feeding box 31 can be increased.

[0044] By increasing the falling path of the bentonite, the working heating plates 32 can heat and dry the bentonite more comprehensively, thereby reducing the moisture in the bentonite. When the crushed bentonite falls between the grinding hopper 41 and the grinding cylinder 5 for grinding into powder, its state will be drier, reducing the phenomenon that the bentonite caking due to its own moisture affects the grinding. The ground bentonite powder can be conveyed outward through the screw conveyor 6 below. Thus, the use of this device can be completed.

[0045] The circuits and controls involved in this utility model are all prior arts and will not be elaborated here.

[0046] The above are only the embodiments of this utility model, and do not limit the patent scope of this utility model accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of this utility model, or directly or indirectly applied in other related technical fields, are equally included in the patent protection scope of this utility model.
