Description

Technical Field

[0001] The present application relates to the technical field of mechanical equipment, and more specifically, to a stirring device. Background Art

[0002] Hexagonal boron nitride (h-BN) is known as "white graphite" because of its layered structure similar to graphite. Correspondingly, h-BN nanosheets are often called "white graphene" and "boron nitride" because of their two-dimensional structure similar to graphene. Compared with graphene, h-BN nanosheets have unique properties, including high energy band gap (insulator), high chemical stability and thermal stability, and ultraviolet luminescence performance. In addition, the high surface area of ​​h-BN nanosheets and the polarity of NB bonds make them have good adsorption properties for a variety of substances. Therefore, h-BN nanosheets have important application prospects in the fields of composite materials, catalyst carriers, gas adsorption and nanoelectronic devices. For most applications, h-BN nanosheets with good performance should have a large sheet size (more than 100nm), a small sheet thickness (less than 10nm) and a good crystal structure (no lattice defects). It is of great significance to achieve good performance, low cost, large-scale, eco-friendly, and continuously controllable production and preparation of h-BN nanosheets.

[0003] In the existing boron nitride nanosheet preparation technology, the raw material (i.e., boron nitride nanosheet) is ground and stirred in an integrated manner by ball milling. Although the production efficiency is greatly improved, some raw materials will inevitably remain in the ball milling device after long-term use, which will lead to a decrease in grinding accuracy and stirring efficiency. Therefore, the grinding and stirring steps need to be performed separately. However, there is no equipment specifically used for stirring boron nitride nanosheets in the prior art.

[0004] Therefore, in order to overcome the defects of the prior art, the present application provides a stirring device. Utility Model Content

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0050] It should also be noted that, in the description of the present application, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment. In the absence of further restrictions, the elements defined by the statement "comprise one..." do not exclude the presence of other identical elements in the process, method, article or equipment including the elements.

[0051] In order to solve the problems existing in the prior art, an embodiment of the present application provides a stirring device. The stirring device can stir a variety of objects to break them up. If the objects are in a sheet structure, the objects can be broken up and thinned at the same time. For example, boron nitride nanosheets can be stirred to break and thin the boron nitride nanosheets to improve the grinding accuracy and stirring efficiency of the boron nitride nanosheets. The following description will be made by taking boron nitride nanosheets as an example. Figure 1-4As shown, it includes a shell 101 with an inner cavity, the shell 101 includes a top plate 102 and a bottom plate; a stirring assembly arranged in the inner cavity of the shell 101; a motor 100 for driving the stirring assembly to rotate; a vibration damping plate 103 arranged above the top plate 102 of the shell 101, the motor 100 is arranged on the vibration damping plate 103; a feed hole extending from the upper surface of the vibration damping plate 103 through the top plate 102 of the shell 101 to the inner cavity of the shell 101, and a feed pipe 104 is installed on the feed hole; a discharge hole extending from the outer surface of the bottom plate of the shell 101 to the inner cavity of the shell 101, and a discharge pipe 106 is installed on the discharge hole; and a protective cover 110 covering the motor 100. The feed pipe 104 is detachably connected to the feed hole; and the discharge pipe 106 is detachably connected to the discharge hole.

[0052] In the above-mentioned embodiment of the present application, the boron nitride nanosheets are transported to the inner cavity of the shell 101 through the feed pipe 104, and the stirring assembly rotates under the drive of the motor 100, thereby stirring the boron nitride nanosheets transported to the inner cavity of the shell 101 to break the boron nitride nanosheets and thin the boron nitride nanosheets, thereby improving the grinding accuracy and stirring efficiency of the boron nitride nanosheets. The stirred boron nitride nanosheets are discharged to the outside of the shell 101 through the discharge pipe 106. Since the motor 100 vibrates when working during the stirring process, the setting of the vibration damping plate 103 can reduce the vibration of the entire device, making the use of the device more stable, and also prolonging the service life of the entire device; the setting of the protective cover 110 can prevent the motor 100 from being hit by external objects and protect the motor 100 from damage.

[0053] Specifically, the stirring device further includes a first cover 105 for blocking the feed pipe 104; and a second cover 107 for blocking the discharge pipe. When the boron nitride nanosheets need to be transported into the inner cavity of the shell 101, the first cover 105 is opened to expose the mouth of the feed pipe 104 to the outside, so that the boron nitride nanosheets can enter the inner cavity of the shell 101. After the transport is completed, the first cover 105 is used to block the feed pipe 104. During the process of the boron nitride nanosheets entering the inner cavity of the shell 101 and the stirring component stirring, the mouth of the discharge pipe 106 is in a blocked state, that is, the second cover 107 is covered on the discharge pipe 106. After the stirring of the boron nitride nanosheets is completed, the second cover 107 is opened to discharge the boron nitride nanosheets from the discharge hole to the outside.

[0054] Furthermore, the discharge hole is located at the center of the bottom plate of the shell 101. In this way, the boron nitride nanosheets in the inner cavity of the shell 101 can be discharged evenly.

[0055] In a specific embodiment, the stirring assembly includes a rotating shaft 111 connected to the motor 100; the rotating shaft 111 passes through the upper surface of the vibration damping plate 103 through the shell top plate 102 and into the inner cavity of the shell 101; and a plurality of stirring rod bodies 112 are formed by horizontally extending outward from the outer wall of the rotating shaft 111. The motor 100 drives the rotating shaft 111 to rotate, and the rotating shaft 111 drives the stirring rod body 112 to rotate, and the stirring rod body 112 stirs the boron nitride nanosheets in the inner cavity of the shell 101. The stirring rod body 112 is detachably connected to the rotating shaft 111, and the stirring rod body 112 has at least one row, preferably two rows, along the extension direction of the rotating shaft 111. When the boron nitride nanosheets enter the inner cavity of the shell 101 through the feeding pipe 104, the stirring rod body 112 rotates driven by the rotating shaft 111, thereby breaking and thinning the boron nitride nanosheets.

[0056] In a specific embodiment, the top plate 102 of the housing 101 is detachably connected to the side wall of the housing 101. This facilitates the installation of the motor 100 and the stirring assembly. Specifically, the vibration damping plate 103 and the top plate 102 are respectively provided with corresponding first mounting holes and second mounting holes, the rotating shaft 111 of the stirring assembly passes through the first mounting hole and the second mounting hole in sequence, and then the stirring rod body 112 is installed on the rotating shaft 111, and finally the top cover is installed on the top of the housing 101. Here, after the stirring assembly, the vibration damping plate 103 and the top plate 102 are installed on the housing 101, the motor 100 can be installed above the vibration damping plate 103 and connected to the rotating shaft 111, or after the stirring assembly, the vibration damping plate 103, the motor 100 and the top plate 102 are connected, the top plate 102 can be installed on the housing 101, and the installation can be performed according to actual conditions.

[0057] In a specific embodiment, the protective cover 110 includes a cover plate 109 in a sheet-like structure; a plurality of protective strips 119 extending from the side edges of the cover plate 109 toward the side wall of the motor 100, and one end of the protective strip 119 away from the cover plate 109 is connected to the side wall of the motor 100. The cover plate 109 can prevent foreign objects from directly colliding with the top of the motor 100, thereby preventing the top of the motor 100 from being affected by the outside world; the protective strips 119 can prevent foreign objects from colliding with the side wall of the motor 100, thereby preventing the side wall of the motor 100 from being affected by the outside world, and the gap between the two protective strips 119 can achieve heat dissipation for the motor 100.

[0058] In a specific embodiment, the stirring device further includes a support column 108 for supporting the housing 101; the support column 108 is detachably connected to the bottom of the housing 101. There are at least three support columns 108, which are evenly fixed to the bottom edge of the housing 101, preferably four. When the housing 101 is a cube, the four support columns 108 are respectively connected to the four corners of the bottom surface of the housing 101.

[0059] In a specific embodiment, the stirring device further comprises a pressure relief assembly arranged on the shell top plate 102; the pressure relief assembly comprises a pressure relief hole 201 penetrating the shell top plate 102; a pressure relief pipe 202 installed on the pressure relief hole 201, the pressure relief pipe 202 is detachably connected to the top plate 102, and specifically, the pressure relief pipe 202 can be inserted into the pressure relief hole 201; and a control ring 203 for controlling the opening and closing of the pressure relief pipe 202. The setting of the pressure relief assembly can adjust the pressure in the inner cavity of the shell 101 so that the pressure in the inner cavity of the shell 101 is equal to the external pressure. Specifically, when the stirring assembly stirs the boron nitride nanosheets, the pressure in the inner cavity of the shell 101 may increase, thereby affecting the stirring of the stirring assembly. At this time, the control ring 203 can be rotated according to the actual situation to control the degree of communication between the pressure relief pipe 202 and the outside world, so that the gas in the inner cavity can be smoothly discharged to the outside world without affecting the use of the stirring device, so that the pressure in the inner cavity of the shell 101 is roughly equal to the external pressure. When the inner cavity of the housing 101 needs to be sealed, the control ring 203 can be rotated to make the pressure relief tube 202 completely sealed. The control ring 203 can control the opening size of the pressure relief tube 203, that is, the degree of connection between the pressure relief tube 203 and the outside world, and can be completely closed (that is, the pressure relief tube 203 is not connected to the outside world), completely open (that is, the pressure relief tube 203 is completely connected to the outside world), and half open (that is, the pressure relief tube 203 is half connected to the outside world and half open).

[0060] In a specific example, the cross section of the housing top plate 102 is larger than the cross section of the vibration damping plate 103; the area of ​​the housing top plate 102 not covered by the vibration damping plate 103 is an exposed area; the pressure relief assembly is arranged in the exposed area. The housing 101 may be a cube, specifically a cube, and the cross section of the vibration damping plate 103 may be circular. When the diameter of the vibration damping plate 103 is equal to the side length of the cube, the exposed area is the four corners of the housing top plate 102, and the pressure relief assembly may be arranged at any one of the four corners.

[0061] The stirring device provided by the present application, when in use, delivers the boron nitride nanosheets to the inner cavity of the housing 101 through the feed pipe 104, the first cover 105 blocks the feed port, the motor 100 is turned on, the rotating shaft 111 of the stirring assembly rotates under the drive of the motor 100, and the rotating shaft 111 drives the stirring rod body 112 to rotate, thereby stirring the boron nitride nanosheets delivered to the inner cavity of the housing 101 to break the boron nitride nanosheets and thin the boron nitride nanosheets. After the stirring is completed, the motor 100 stops rotating, the second cover 107 is opened, and the stirred boron nitride nanosheets are discharged to the outside of the housing 101 through the discharge pipe 106. The grinding accuracy and stirring efficiency of the boron nitride nanosheets are improved.

[0062] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description.
