Description

[0001] The invention belongs to the technical field of cement dispersion, and in particular relates to a dispersion device for preparing a graphene cement material. Background Art

[0002] Graphene cement is a new type of building material prepared by introducing graphene materials into cement-based materials; the addition of graphene can improve various properties of cement-based materials, such as mechanical strength, toughness, durability, impermeability, crack resistance, etc.; therefore, graphene cement has gradually been widely used. To prepare graphene cement, graphene needs to be added to cement, so graphene needs to be dispersed. The following are some common graphene cement dispersion methods: surface modification, optimization of preparation process, use of dispersants and ultrasonic treatment, etc.;

[0003] In the prior art, in order to reduce costs, graphene cement is usually mixed by mechanical stirring. Mechanical stirring uses powerful mechanical stirring equipment to ensure that graphene is fully mixed in cement. However, existing stirring devices usually apply shear force to cement and graphene, and some cement and graphene cannot be well dispersed and mixed. Summary of the invention

[0004] In view of the problems raised by the above background technology, the purpose of the present invention is to provide a dispersion device for preparing graphene cement material to solve the problems raised by the above background technology.

[0005] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A dispersion device for preparing graphene cement material comprises a columnar dispersion box, wherein extrusion parts and feed guide plates are sequentially arranged in the dispersion box from top to bottom, and the number of the feed guide plates is two, which are symmetrically arranged on both sides of the dispersion box, and the feed guide plates are located on the side walls of the dispersion box, and the feed guide plates are connected with the outside and inside of the dispersion box, and a receiving frame rotatably connected to the dispersion box is provided below the feed guide plates located inside the dispersion box, and a cylindrical baffle is fixedly connected to the edge of the side opening of the receiving frame, a rotating mechanism assembled with the dispersion box is provided on the lower side of the receiving frame, a sieve hole is provided on the bottom side of the receiving frame, and a collecting piece assembled with the dispersion box is provided below the receiving frame.

[0007] It is further defined that the extrusion member includes a pressure cylinder fixedly assembled and connected to the upper side of the dispersion box, the output shaft of the pressure cylinder is assembled and connected to a circular pressure plate, the pressure plate is located directly above the material receiving frame, the pressure plate is located inside the baffle when it moves to the lower part, and the edge of the pressure plate is located on the inner side of the feed guide plate and does not interfere with the feed guide plate.

[0008] It is further defined that a circular support ring is fixedly connected to the lower edge of the material receiving frame, an elastic part assembled and connected to the dispersion box is provided on the lower side of the support ring, a cylindrical guard plate located on the inner side of the elastic part is fixedly connected to the lower side of the material receiving frame, and a first limit plate fixedly connected to the side wall of the dispersion box is provided on the upper side of the support ring.

[0009] It is further defined that the rotating mechanism includes a gear ring fixedly connected to the outer ring of the support ring, the outer side of the dispersion box is assembled and connected with a gear that is meshed and transmission connected to the gear ring, the thickness of the gear is greater than the thickness of the gear ring, and the gear ring remains meshed with the gear when it moves downward, the upper and lower sides of the gear are rotatably connected to a mounting plate fixedly connected to the dispersion box, the upper side of the mounting plate is assembled and connected with a motor, and the output shaft of the motor is transmission connected to the gear shaft.

[0010] It is further defined that the collecting member includes a material receiving plate fixedly connected to the lower portion of the dispersion box, a driving member is provided below the middle portion of the material receiving plate, the driving member is rotatably connected to a rotating block rotatably connected to the material receiving plate, a push plate is fixedly connected to the side edge of the rotating block, a material guide trough extending from the middle portion to the lower portion of the edge is provided on the upper side of the material receiving plate, and the dispersion box is provided with a material outlet of the material guide trough.

[0011] It is further defined that the number of the push plates is four, a gap is left between the lower sides of two push plates located on the same line and the receiving plate, and the cross-section of the push plates is a T-shape that is wide at the top and narrow at the bottom.

[0012] It is further defined that the dispersion box is fixedly connected to a second limiting plate in the middle of the elastic member in the up-down direction.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The invention is cleverly designed, and the materials are dispersed by extruding the materials through the extrusion piece. During the material feeding process, the material receiving frame rotates so that the two materials are preliminarily mixed, and in the subsequent processing, the materials are mixed more evenly.

[0015] In the present invention, the material receiving frame is rotatably connected to the dispersion box, and the material receiving frame is driven to rotate by a rotating mechanism. The thickness of the gear is greater than the gear ring, so that the material receiving frame remains engaged with the gear when displacement occurs in the up and down directions, so that the gear can drive the material receiving frame to rotate.

[0016] The present invention provides an elastic member on the lower side of the material receiving frame to buffer the impact force on the material receiving frame when the extruding member descends, thereby reducing the life of the extruding member connecting the material frame and enabling the material receiving frame to have an up-and-down displacement. When the extruding member is reset, the elastic member is reset and drives the material receiving frame to move up and down during the rebound process, thereby enabling the extruded material to be sieved out of the sieve holes of the material receiving frame more quickly. At the same time, the first limit plate can limit the material receiving frame from continuing to move upward, thereby limiting the moving path of the material receiving frame.

[0017] The present invention receives the material under the sieve through the receiving plate, pushes the material into the material guide trough through the push plate to discharge the dispersed material, the push plate in contact with the receiving plate pushes the material above the receiving plate into the material guide trough, and the excess material is driven to the top of the receiving plate, and the push plate with a gap between the receiving plate and the material is further polished to achieve extrusion dispersion of the graphene cement material.

[0033] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0034] Embodiment 1: Figure 1-7 As shown, a dispersion device for preparing graphene cement material includes a columnar dispersion box 1, in which an extrusion piece 2 and a feed guide plate 3 are arranged in sequence from top to bottom. There are two feed guide plates 3, which are symmetrically arranged on both sides of the dispersion box 1. The feed guide plate 3 is located on the side wall of the dispersion box 1, and the feed guide plate 3 is connected with the outside and the inside of the dispersion box 1. A receiving frame 4 rotatably connected to the dispersion box 1 is provided below the feed guide plate 3 located inside the dispersion box 1, and a cylindrical baffle 41 is fixedly connected to the edge of the upper opening and the side of the receiving frame 4, a rotating mechanism 5 assembled and connected to the dispersion box 1 is provided on the lower side of the receiving frame 4, a sieve hole is provided on the bottom side of the receiving frame 4, and a collecting piece assembled and connected to the dispersion box 1 is provided below the receiving frame 4.

[0035] By adopting the technical solution of this embodiment, cement material and graphene material enter the dispersion box from two feed guide plates 3 respectively and arrive at the receiving frame 4. During the feeding process, the receiving frame 4 rotates driven by the rotating mechanism 5, so that the two materials are preliminarily mixed during the feeding process. A rotating ring is provided above the receiving frame 4 and is slidably connected to the side wall of the dispersion box 1, so that the position of the receiving frame 4 will not shift during the rotation process, so that the two materials are mixed more evenly in the subsequent processing process. After the rotation of the receiving frame 4 is stopped by controlling the rotating mechanism 5, the initial position of the extruder 2 is located above the feed guide plate 3. The extruder 2 is controlled to move downward to contact the material, thereby extruding and dispersing the block cement and graphene materials. After the extruder 2 rises, the receiving frame 4 is controlled to rotate by the rotating mechanism 5. During the rotation of the receiving frame 4, the material is screened out from the sieve holes on the lower side of the receiving frame 4, and the mixture of cement and graphene falls into the bottom of the dispersion box 1 through the sieve holes. At the same time, during the screening process, the cement and graphene are further mixed.

[0036] Example 2: Reference Figure 1 and 3-4: This embodiment further defines the extrusion member 2 on the basis of the first embodiment. The extrusion member 2 includes a pressure cylinder 21 fixedly assembled and connected to the upper side of the dispersion box 1. The output shaft of the pressure cylinder 21 is assembled and connected with a circular pressure plate 22. The pressure plate 22 is located directly above the material receiving frame 4. When the pressure plate 22 moves to the lower part, it is located inside the baffle 41. The edge of the pressure plate 22 is located on the inner side of the feed guide plate 3 and does not interfere with the feed guide plate 3. In this embodiment, the contact between the pressure plate 22 and the material is controlled by controlling the movement of the output shaft of the pressure cylinder 21. The material is squeezed by the pressure plate 22 to disperse the graphene and cement. When the pressure plate 22 moves downward into the baffle 41, the pressure plate 22 is slidably connected to the baffle 41, thereby processing all the materials in the baffle 41. The initial position of the pressure plate 22 is located above the feed guide plate 3 and will not interfere with the material entering the feed guide plate 3 into the material receiving frame 4.

[0037] Example 3: Reference Figure 4-6 : This embodiment adds the following structure on the basis of the first embodiment: a circular support ring 42 is fixedly connected to the lower edge of the material receiving frame 4, an elastic member 11 assembled and connected to the dispersion box 1 is provided on the lower side of the support ring 42, a cylindrical guard plate 43 located on the inner side of the elastic member 11 is fixedly connected to the lower side of the material receiving frame 4, and a first limit plate 12 fixedly connected to the side wall of the dispersion box 1 is provided on the upper side of the support ring 42. In this embodiment, the support ring 42 is slidably connected to the elastic member 11, and the upper part of the elastic member 11 supports the support ring 42. The first limit plate 12 is used to prevent the elastic member 11 from driving the material receiving frame 4 to continue to rise when it rebounds. The guard plate 42 separates the material from the elastic member 11 to prevent the material from contacting the elastic member 11 during the falling process. At the same time, when the material receiving frame 4 moves downward, the guard plate 42 moves downward. When the extrusion member 2 moves downward to extrude the material, the material receiving frame 4 is also moved downward. The lower side of the material receiving frame 4 squeezes the elastic member 11. The elastic member 11 can reduce the impact force on the material receiving frame 4 through elastic deformation, thereby extending the life of the material receiving frame 4. When the extrusion member 2 is reset, the elastic member 11 is reset and moves back and forth at the same time, so that the material receiving frame 4 vibrates in the up and down directions, which is beneficial to sifting the material out of the sieve holes of the material receiving frame 4.

[0038] Example 4: Reference Figure 1-3: The rotating mechanism 5 includes a toothed ring 51 fixedly connected to the outer ring of the support ring 42, and a gear 52 meshing and transmission-connected with the toothed ring 51 is assembled and connected on the outer side of the dispersion box 1. The thickness of the gear 52 is greater than that of the toothed ring 51. When the toothed ring 51 moves downward, it also keeps meshing with the gear 52. The upper and lower sides of the gear 52 are rotatably connected with a mounting plate 53 fixedly connected to the dispersion box 1. The upper side of the mounting plate 53 is assembled and connected with a motor 54, and the output shaft of the motor 54 is transmission-connected with the gear shaft. In this embodiment, the rotating mechanism 5 is used to drive the material receiving frame 4 to rotate, and the rotation of the motor 54 drives the gear shaft to rotate, and the rotation of the gear shaft drives the toothed ring 51 to rotate. The first limit plate 12 prevents the material receiving frame 4 from continuing to rise while preventing the toothed ring 51 from being disengaged from the gear 52. A sealing plate is fixedly connected between the upper and lower mounting plates 53 to prevent the gear 52 from being directly exposed to the outside, thereby improving the safety of the device.

[0039] Example 5: Reference Figure 4 and Figure 7 :This embodiment further defines the collecting member on the basis of the first embodiment. The collecting member includes a receiving plate 6 fixedly connected to the lower part of the dispersion box 1. A driving member 61 is provided below the middle of the receiving plate 6. The driving member 61 is rotatably connected to a rotating block 62 rotatably connected to the receiving plate 6. A push plate 63 is fixedly connected to the edge of the side of the rotating block 62. A material guide trough extending from the middle to the lower edge is provided on the upper side of the receiving plate 6. The dispersion box 1 is provided with a material outlet of the material guide trough. In this embodiment, the receiving plate 6 is used to collect the materials falling from the sieve holes. The upper part of the rotating block 62 is arc-shaped. The materials falling above the rotating block 62 fall along the rotating block 62 to the upper part of the receiving plate 6. The push plate 63 is used to push the materials into the material guide trough. The materials flow out of the outlet along the material guide trough.

[0040] Example 6: Reference Figure 7 :This embodiment further defines the push plate 63 on the basis of the fifth embodiment. The number of the push plates 63 is four. There is a gap between the lower sides of the two push plates 63 located on the same line and the material receiving plate 6. The cross section of the push plates 63 is a T-shape with a wide top and a narrow bottom. In this embodiment, the push plates 63 are used to push the material into the material guide trough so that the material moves along the material guide trough to the outside of the dispersion box 1. Because the flow rate of the material in the material guide trough is limited, when the material guide trough is filled, the inclination arc of the material guide trough is large enough to allow the material to slide out along the material guide trough. The material above the material receiving plate 6 moves to the top of the material receiving plate 6 under the push of the push plates 63. The push plates 63 with a gap between them and the material receiving plate 6 grind the material above the material receiving plate 6 during the rotation process. The push plates 63 in close contact with the material receiving plate 6 push the material above the material receiving plate 6 into the material guide trough.

[0041] Embodiment 7: Reference Figure 3:This embodiment adds the following structure on the basis of the third embodiment: the dispersion box 1 is fixedly connected with a second limit plate 13 in the middle of the upper and lower directions of the elastic member 11. In this embodiment, the second limit plate 13 is used to prevent the elastic member 11 from being subjected to a force exceeding the load limit of the elastic member 11. When the extrusion member 2 is pressed down so that the lower part of the material receiving frame 4 contacts the second limit plate 13, the extrusion member 2 stops descending and also stops pressing down on the elastic member 11.

[0042] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0043] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
