Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a mixing mixer. Background Art

[0002] A mixer is a device that mixes various raw materials evenly. It is not only used to mix cement, sand, various dry mortar and other construction materials, but also can be used to mix various chemical materials in the production process.

[0003] At present, the mixer puts the material to be mixed into the cavity, and then uses a motor to drive one or several stirring rods to rotate in the cavity to achieve mixing of various materials. However, in actual use, different and large amounts of raw materials need to be stirred under different processes. When the internal viscosity or friction of the raw materials to be mixed is large, more stirring rods will increase the contact area between the stirring rods and the raw materials, that is, increase the stirring resistance, resulting in the equipment being unable to start. When the internal viscosity or friction of the raw materials to be mixed is small, the fluidity of the raw materials is large. When fewer stirring rods are used, the stirring effect of the raw materials in the vertical direction will be poor, resulting in the need to use different mixers for the mixing of different raw materials, increasing costs.

[0004] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0007] By adopting the above technical solution and utilizing the movable structure of the fan blades on the rotating shaft, different numbers of rotating shafts can be adaptively placed in the raw materials for stirring according to different quantities and types of raw materials, thereby greatly increasing the use effect of the equipment.

[0008] The utility model is further configured as follows: the cross-sectional diameter of the rotating shaft increases as the distance from the upper cover to the cavity increases, and is divided into three sections; the fan blades are divided into two groups, one group of fan blades is connected to a section of the rotating shaft away from the upper cover through a fixing device, and the other group of fan blades is connected to a middle section of the rotating shaft or a section of the rotating shaft close to the upper cover through a fixing device and a storage device.

[0009] By adopting the above technical solution, the fan blades are fixed to the rotating shaft by using a fixing device, so that the rotating shaft drives the fan blades to rotate and stir. At the same time, the fixing device can also loosen the fan blades and move the fan upward to the storage device position. The fan blades located at the storage device position are disconnected from the power of the rotating shaft, so that the rotating shaft only drives the fan blades extended into the raw material to rotate, reducing the kinetic energy of the rotating shaft transferred to the upper fan blades, and increasing the stirring effect of the lower fan blades on the raw material.

[0010] The utility model is further configured as follows: the fixing device includes a plurality of threaded columns, the surface of the rotating shaft is provided with a plurality of threaded connection holes along the axial direction of the rotating shaft perpendicular to the rotating shaft, the fan blades are penetrated by a through screw hole, the threaded columns are screwed into the through screw hole and meshed with the threaded connection hole.

[0011] By adopting the above technical solution, when the fan blades need to be fixed, the fan blades are fixedly connected to the rotating shaft using threaded columns. When the fan blades need to be moved up and down, the fan blades can be moved by rotating the threaded columns in the opposite direction.

[0013] By adopting the above technical scheme, the lower guide block, the first upper guide block and the second upper guide block are used to limit the rotation of the fan blades along the axial direction of the rotating shaft, thereby increasing the connection effect between the rotating shaft and the fan blades, and then the structure in which the first upper fan blade and the second upper fan blade are connected to the first upper guide block and the second upper guide block is used, and the second upper guide block is used to limit the second upper fan blade and limit its downward movement to the extreme position, thereby preventing the second upper fan blade from being unstablely connected to the rotating shaft during stirring and causing the second upper fan blade to continue to move downward, preventing the second upper fan blade from contacting the first upper fan blade, thereby increasing safety.

[0014] The utility model is further configured as follows: the storage device includes a bearing rotatably connected to the first section surface of the rotating shaft close to the upper cover, and the outer diameter of the bearing is the same as the diameter of the middle section of the rotating shaft, and a fixed threaded hole is opened on the outer surface of the bearing away from the upper cover, and a threaded nail is engaged in the fixed threaded hole.

[0015] By adopting the above technical solution, when the threaded column is loosened and the first upper blade and the second upper blade are moved along the axis direction of the rotating shaft, the first upper blade and the second upper blade are moved to the bearing position, and the inner walls of the first upper blade and the second upper blade are connected to the outer surface of the bearing, and the inner diameter of the bearing is used to engage with the surface of the first section of the rotating shaft. The structure connecting the outer surface of the bearing to the first upper blade and the second upper blade disconnects the first upper blade and the second upper blade from the power of the rotating shaft, and then the threaded nails engaged with the outer surface of the bearing limit the downward movement of the first upper blade and the second upper blade, thereby controlling the rotating shaft to be connected to different numbers of blades, thereby increasing the use effect.

[0016] The utility model is further configured as follows: a plurality of accommodating cavities for accommodating fan blades are provided at one end of the upper cover close to the outer shell.

[0017] By adopting the above technical solution, the fan blades disconnected from the rotating shaft are stored in the accommodating cavity, further limiting the movement of the first upper fan blades and the second upper fan blades to prevent the vibration, installation, and disassembly during normal operation from causing damage to the lower fan blades and the first upper fan blades, thereby increasing their service life.

[0018] The utility model is further configured as follows: the upper first fan blade, the second upper fan blade and the lower lower fan blade are oriented in opposite directions.

[0019] By adopting the above technical solution, when the rotating shaft rotates, the lower fan blades below drive the raw materials to move downward in the vertical direction, and the first upper fan blades and the second upper fan blades above drive the raw materials to move upward, thereby increasing the stirring and mixing of the raw materials in the vertical direction and improving product quality.

[0020] In summary, the utility model has the following beneficial effects:

[0021] By utilizing the up and down movement of the fan blades on the rotating shaft and the detachable structure, different numbers of fan blades can be adjusted to extend into the raw materials for stirring, so as to adapt to the stirring of different types and quantities of raw materials and increase the use effect; at the same time, by utilizing the structural design of the upper and lower sets of fan blades in different directions, the fan blades can move the raw materials in the middle position downward and upward in the vertical direction, thereby increasing the stirring and mixing effect of the raw materials in the vertical direction.

When the number of fan blades needs to be reduced, rotate the threaded column to disconnect all the fan blades from the rotating shaft 13, and then move the several fan blades located on the top upward along the axial direction of the rotating shaft 13 to the bearing 19 position. Preferably, move the two fan blades of the upper group to the bearing 19 position, that is, move the first upper fan blade 17 and the second upper fan blade 18 to the bearing 19 position, and then move the lower fan blade 16 below to the position of the appropriate threaded connection hole 21 on the third section of the rotating shaft 13, and then fix the lower fan blade 16 to the rotating shaft 13 through the threaded column, and at the same time screw the threaded nail into the fixed threaded hole on the bearing 19, so that the threaded nail and the first upper fan blade 17 and the second upper The blades 18 abut against and restrict the downward movement of the two, and at the same time, the bearing 19 completes the disconnection between the first upper blade 17 and the second upper blade 18 and the rotating shaft 13, so that the rotating shaft 13 only drives the lower blade 16 to rotate, that is, the control of different numbers of blades on the rotating shaft 13 is completed, and the position of the lower blade 16 on the rotating shaft 13 can also be adjusted to further meet the conditions for stirring different raw materials and increase the stirring effect.
