Description

Technical Field

[0001] The utility model belongs to the technical field of stirring equipment and relates to a siphon type dispersion disk. Background Art

[0002] The high-speed rotation of the dispersion disc makes the slurry in the cylinder present a rolling circulation, and a high-power device will produce a large vortex. The powder floating on the slurry will quickly descend to the bottom of the vortex along the spiral. A turbulent zone is formed at the edge of the dispersion disc 2.5-5cm. In this area, the powder particles are subjected to strong shear and impact, allowing them to be quickly dispersed into the slurry. Outside this area, the upper and lower flow beams of the stroke allow the slurry to be fully circulated and turned. If the bottom of the dispersion disc presents a laminar flow state, the interaction between the liquid layers of different speeds is called the effect of viscosity shear force, which can achieve a good dispersion effect.

[0003] However, although the dispersion disk inside the existing stirring device has a simple structure, when the dispersion disk rotates at high speed to disperse the slurry, the slurry rushes to the wall of the device under the action of centrifugal force, and the liquid level in the center drops to form a large vortex. The higher the rotation speed, the deeper the vortex formed, resulting in a decrease in the effective volume, and almost no axial mixing, resulting in a decrease in the stirring effect and a poor dispersion effect. In order to achieve a uniform dispersion effect, the dispersion time has to be extended, which reduces production efficiency. Summary of the invention

[0006] As a further improvement of the utility model, the outer periphery of the dispersion disc is evenly distributed with bevel angles, and the upper dispersion teeth, the upper dispersion teeth and the lower dispersion teeth are arranged at intervals above and below the bevel angles.

[0007] As a further improvement of the utility model, the dispersion disc body is circular, and the bevel angle is between 20-30°.

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0021] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the utility model described herein. In addition, similar terms such as "including" and "having" mean that in addition to those contents already listed in "including" and "having", other contents that have not been listed can also be "included" and "having"; for example, a process, method, system, product or device that can include a series of steps or units is not necessarily limited to those steps or units that have been clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0022] Due to the angle of the drawing, some components may not be drawn, but their positions and connection relationships can be partially understood based on the text expression.

[0023] like Figure 1 As shown, the utility model is a siphon type dispersion disk, comprising a dispersion disk body 1, wherein an upper dispersion structure and a lower dispersion structure are respectively arranged at the upper and lower parts of the outer circumference of the dispersion disk body 1, and a material guide structure is arranged in the middle of the dispersion disk body 1.

[0024] The upper dispersing structure is upper dispersing teeth 2 , which are evenly distributed on the upper periphery of the dispersing disc body 1 ; the lower dispersing structure is lower dispersing teeth 3 , which are evenly distributed on the lower periphery of the dispersing disc body 1 .

[0025] In order to improve the dispersing effect, the outer periphery of the dispersing disc body 1 is evenly distributed with bevel angles 1-1, and the upper dispersing teeth 2, the upper dispersing teeth 2 and the lower dispersing teeth 3 are arranged at intervals above and below the bevel angle 1-1.

[0026] Specifically, the dispersion disc body 1 is circular, and the bevel angle 1-1 is between 20 and 30 degrees. The upper dispersion teeth 2 and the lower dispersion teeth 3 are vertically arranged to increase the contact area with the material.

[0027] The upper dispersing teeth 2 and the lower dispersing teeth 3 are made by a bending process. In order to avoid interference during bending, avoidance grooves 1 - 2 are provided between adjacent bevel angles 1 - 1 .

[0028] The material guiding structure includes a flow port 4, which is evenly distributed in the middle of the dispersion disk body 1, and a guide plate 5 is provided on the flow port 4. The inclination angle of the guide plate 5 is between ±20-40°, and the direction of the guide plate 5 is opposite to the direction of the dispersion disk. The guide plate 5 sucks the material into the flow port 4 through the action of the pressure difference.

[0029] like Figure 2As shown, when the inclination angle of the guide plate 5 is positive, the guide plate 5 transfers the material from the lower layer to the upper layer of the dispersion disc 1. When the inclination angle of the guide plate 5 is negative, the guide plate 5 transfers the material from the upper layer to the lower layer of the dispersion disc 1.

[0030] Specifically, the flow opening 4 is rectangular, which has the advantage of being easy to process.

[0031] In this embodiment, five flow openings 4 are evenly distributed in the middle of the disk body 1 , and the five guide plates 5 are located on the same side of the five flow openings 4 .

[0032] A connection hole 1-3 is provided in the middle of the dispersion disc body 1, and a positioning hole 1-4 is provided outside the connection hole 1-3. The connection hole 1-3 and the positioning hole 1-4 are used to install the cover plate. The dispersion disc body 1 is connected to the drive shaft through the cover plate. The contact area between the drive shaft and the dispersion disc body 1 is increased through the transition of the cover plate, so as to avoid the dispersion disc body 1 from being twisted and damaged due to uneven stress during the dispersion of materials.

[0033] The working process of the utility model is as follows:

[0034] At the flow port 4, the pressure of the material at the lower part of the dispersion disk is greater than the pressure at the upper part of the dispersion disk. Under the action of the pressure difference between the upper and lower parts, the material will pass through the flow port 4 from bottom to top, flow along the guide plate 5, and produce flow and mixing in the axial direction. The axial flow of the slurry changes the effect of the centrifugal force on the slurry at a macro level, reduces the formation of the central vortex, increases the effective volume, and at the same time causes the slurry to be mixed in the axial direction, thereby improving the slurry mixing efficiency.

[0035] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
