Detailed Description

Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.

A variable speed homogenizer according to an embodiment of the present invention is described in detail below with reference to the accompanying drawings.

Example 1

The invention provides a variable speed homogenizer, as shown in the figure, which comprises a body 1, wherein a plurality of Tesla valves are arranged in the body 1, any two adjacent Tesla valves are communicated through a connecting pipeline 2, each Tesla valve is sequentially communicated with the connecting pipeline 2 to form a flow passage for fluid to pass through, a feed inlet 7 and a discharge outlet 8 are arranged on the outer side wall of the body 1, the feed inlet 7 and the discharge outlet 8 are respectively communicated with two ends of the flow passage, and at least one bending pipe 3 for changing the flow direction of fluid in the connecting pipeline 2 is arranged on the connecting pipeline 2.

In the present embodiment, the tesla valve is preferably of unitary construction with the body 1. The main pipe extending from the feeding hole 7 to the discharging hole 8 is formed in the body 1 in a material reducing manner, a plurality of functional areas are sequentially arranged along the main pipe, a plurality of arc-shaped branch pipes are formed in each functional area in a processing manner, two ends of each arc-shaped branch pipe are communicated with the main pipe, thereby forming Tesla valves in each functional area, wherein the part of the main pipe between each Tesla valve is used as a connecting pipeline 2, and at least one position of the connecting pipeline 2 is bent, so that a bent pipe 3 is formed. The whole pipeline formed by all the tesla valves and the connecting pipeline 2 is a flow passage in the embodiment. In this embodiment, the structure of the tesla valve formed by interconnecting each arc-shaped branch pipe and the main pipe is an existing tesla valve, which belongs to the common knowledge in the art, so the structure of the tesla valve is not described one by one in this embodiment.

Example two

The bending tube 3 in the first embodiment includes an injection section, a bending section and an injection section which are sequentially communicated, when fluid is injected into the bending section from the injection section, the fluid collides with the inner wall of the tube of the bending section, and flows out from the injection section in different directions from the injection section after the collision, and solid particles contained in the fluid and the inner wall of the tube are broken in the collision process, so as to achieve a homogenizing effect. Taking fluid as graphene slurry as an example, graphite particles contained in the graphene slurry can continuously collide at the bending section position of the bending tube 3, and the local position is rapidly worn after being impacted by the graphite particles, so that the problem of low service life is caused. For this reason, the improvement of this embodiment is that: the corner of the bending tube 3 is embedded with a collision body 4 at a position corresponding to the fluid flowing direction. Namely, a collision body 4 is arranged in the bending section of the bending tube 3, the collision body 4 is embedded on the inner wall of the bending tube 3, the position of the collision body 4 corresponds to the flowing direction of the fluid from the injection section to the inside of the bending section, so that the fluid collides with the collision body 4 and then turns when flowing into the bending section from the injection section, and finally the fluid is injected from the injection section. In this embodiment, the impact force of the fluid is concentrated on the collision body 4, so that impact abrasion to the inner wall of the bent tube 3 is greatly reduced, and the service life of the bent tube 3 is prolonged.

In this embodiment, the collision body 4 is made of a wear-resistant material. Preferably the collision body 4 is made of diamond material or the collision body 4 is made of cubic boron nitride material.

Further, the inner wall of the flow channel in the body 1 is provided with at least one protective layer, and the protective layer is plated on the inner wall of the flow channel, thereby reducing the damage to the inner wall of the flow channel during the high-pressure and high-speed flow of the fluid. Preferably, the protective layer is a diamond coating.

Example III

In order to make the effect of breaking graphite particles more in the homogenizing process of the graphene slurry in the prior art, thereby obtaining a better homogenizing effect, the jet flow of the graphene slurry needs to obtain a faster speed, so that the graphene slurry needs to obtain a higher pressure, and a faster flow speed is exchanged by the pressure. However, too high a slurry pressure not only brings serious challenges to the tightness and safety during the operation of the apparatus, but also increases the cost of the apparatus by a multiple. Particularly, graphite solid particles contained in graphene slurry, the sealing performance of a piston pump mainly used in the existing graphene industry is reduced due to fixed particles contained in the slurry, the piston pump which can generally provide pure water pumping pressure up to 600MPA can only pressurize the slurry to about 100MPA when being used for pumping the graphene slurry, and the technology which is more at the front in the existing graphene field generally needs to pressurize the slurry to an ultrahigh pressure state exceeding 250MPA, so that the ultrahigh slurry pressure requirement is also a difficult problem in the existing graphene industry. Therefore, in the prior art, under the condition that the pressure cannot meet the requirement, the same slurry can be repeatedly homogenized only by increasing the homogenization times, so that the quality of the final graphene slurry is improved, the homogenization efficiency is greatly reduced, the production cost is improved, and the industrialized popularization is not facilitated.

To this end, the present embodiment proposes that the velocity of the fluid can be further increased by not increasing the initial pressure of the fluid, which can also enhance the homogenizing effect during the homogenizing process, and in particular, as shown in fig. 1 and 2, the tesla valve includes a forward tesla valve 5 that is positively installed on the flow passage for accelerating the flow velocity of the fluid in the flow passage. The forward tesla valve 5 is a tesla valve connected in series in the forward direction on the flow channel, and the fluid can be accelerated by the forward tesla valve 5 when the fluid flows into the feed port and passes through the forward tesla valve 5.

As a preferable example of this embodiment, two tesla valves in the body 1 are two, the two tesla valves are forward tesla valves 5, the two forward tesla valves 5 are sequentially arranged at intervals along the flow direction of the flow channel, the two forward tesla valves 5 are communicated through a connecting pipeline 2, the connecting pipeline 2 is provided with two bending pipes 3, and the connecting pipeline 2 formed by the two bending pipes 3 is in a zigzag shape.

The homogenization process of this embodiment: the fluid enters the flow channel from the feed port 7 on the left end face of the body 1, the fluid is accelerated for the first time when passing through the first forward Tesla valve 5, the accelerated fluid impacts the collision body 4 in the first bending tube 3 due to the direction change of the bending tube 3 at the position of the first bending tube 3, so that the fluid is crushed for the first time, then the fluid after the first time is continuously fed into the second bending tube 3, the fluid after the first time is crushed for the second time in the direction change process of the second bending tube 3, the fluid after the two times is accelerated by the second forward Tesla valve 5 and is sprayed out from the discharge port 8 on the right end face of the body 1, at the moment, the flow velocity of the fluid after the two times is accelerated is larger than the initial flow velocity when flowing in from the feed port 7, the fluid is instantaneously decompressed due to the sudden expansion of the volume space in the process of the fluid sprayed out from the discharge port 8, and the fluid can be atomized due to the cavitation effect of the fluid, and the fluid can be crushed for the third time. In the embodiment, the homogenizing effect of the fluid after three times of crushing is obviously better than that of the conventional T-shaped or Y-shaped homogenizing valve.
