Description
Technical Field
[0001] The present application relates to the technical field of manufacturing stirring devices, and in particular to a splash-proof device for a stirring machine. Background Art
[0002] A mixer is a machine with a bladed shaft that rotates in a cylinder or tank and mixes various raw materials to form a mixture or a suitable consistency. It is usually used to mix paint, concrete and other materials. When a mixer used to mix paint, the mixer can crush, disperse and mix the paint. The high-speed rotating shaft drives the blades to shear, crush and disperse the paint, so as to achieve the effect of quickly mixing, dissolving and dispersing the paint.
[0003] In order to improve the efficiency of mixing, the shaft speed in most of the current mixers is very high. However, when the shaft drives the blades at high speed to mix the paint, the paint is subjected to a large external mixing force, which will cause splashing in the mixing barrel, forming wall hangings on the inner wall of the mixing barrel, and even splashing out of the barrel, causing serious waste of paint.
[0004] In view of the above-mentioned related problems, the inventor believes that a splash-proof device for a mixer should be provided to reduce the possibility of paint splashing in the mixing barrel, thereby reducing the waste of paint. Utility Model Content
[0005] In order to reduce the possibility of paint splashing in the mixing barrel, the present application provides a mixer splash-proof device, which adopts the following technical solution:
[0006] A splash-proof device for a mixer comprises a mixing barrel, a mixing component fixedly installed inside the mixing barrel, and a splash-proof component fixedly installed on the inner wall of the mixing barrel, wherein the splash-proof component comprises a splash-proof baffle fixedly connected to the inner wall of the mixing barrel and a flow groove opened on the splash-proof baffle.
[0007] By adopting the above technical scheme, when the stirring component rotates at a high speed and performs a series of operations such as shearing, crushing, and dispersing on the paint in the stirring barrel, the paint will rotate continuously and fixedly in the stirring barrel along with the stirring component in the direction of rotation of the rotating shaft, and the splash-proof component fixedly installed on the inner wall of the stirring barrel can slow down the high-speed rotating paint. Specifically, the splash-proof baffle is used to block part of the paint close to the inner wall of the stirring barrel. During its rotation, the splash-proof baffle can reduce the rotation speed of the paint, thereby reducing the magnitude of the relative force generated after the paint collides with the inner wall of the stirring barrel, so that the splash-proof device in the present application can reduce the possibility of splashing of the paint after being subjected to external force, thereby reducing the waste of the paint; and the present application also provides a flow groove on the splash-proof baffle, and the flow groove can allow part of the paint that is slowed down by the splash-proof baffle to pass through. On the basis of the paint slowing down by the splash-proof baffle, the paint is slightly accelerated, so as to avoid the phenomenon of insufficient shearing, crushing, and dispersion of the paint due to excessive deceleration as much as possible, thereby effectively improving the practicality and operability of the device.
[0008] Optionally, the vertical length of the splash guard is greater than the vertical length of the stirring assembly.
[0009] By adopting the above technical solution, the present application utilizes the vertical length of the splash shield to be greater than the vertical length of the stirring assembly, further improving the deceleration and splash-proof effects of the splash shield. When the stirring assembly stirs the paint and the splash shield slows down the paint, the stirring and deceleration effects depend largely on the vertical lengths of the two. The assembly with a longer vertical length can act on a longer vertical distance, that is, a larger amount of paint. Since the vertical length of the splash shield is greater than the vertical length of the stirring assembly, the amount of paint decelerated by the splash shield assembly is greater than the amount of paint stirred by the stirring assembly. By setting different vertical lengths for the two components, the present application achieves the effect that the two components can be effective for different amounts of paint, further improving the deceleration effect of the splash shield on the paint, and further reducing the possibility of splashing of the paint after being subjected to external force, reducing the degree of waste of the paint.
[0010] Optionally, the anti-splash baffle includes an anti-splash edge arranged on a side away from the bottom of the mixing barrel and a convergence edge arranged on a side close to the mixing component, and the convergence edge gradually converges toward the center position of the mixing barrel.
[0011] By adopting the above technical solution, the present application is provided with a splash-proof edge and a gathering edge on the splash-proof baffle, and the gathering edge gradually gathers toward the center of the mixing barrel, which can effectively reduce the possibility of the paint splashing out of the barrel. Since the paint can only splash out from the surface layer of the whole paint when splashing, and the paint needs to overcome its own gravity to do work when splashing, this requires the paint to have a certain rotation speed to collide with other objects and generate a sufficiently large force. When the gathering edge gradually gathers toward the center of the mixing barrel, the closer to the paint layer above the mixing barrel, the greater the amount of paint that is decelerated inside, and the degree of decrease in the overall speed will be greater than the degree of decrease in the overall speed of the paint layer far from the top of the mixing barrel, that is, the degree of decrease in the speed of the part of the paint that can splash out of the barrel is greater than the degree of decrease in the paint at other positions, and the force generated by the paint that can splash out of the barrel after colliding with other objects is greatly reduced, and it is difficult to overcome its own gravity to do work and splash out of the barrel. Therefore, the present application further reduces the waste of paint by setting a gathering edge that gradually gathers toward the center of the mixing barrel.
[0012] Optionally, the thickness of the splash guard at a corresponding position is proportional to the distance from the bottom of the mixing barrel.
[0013] By adopting the above technical solution, the present application sets the thickness of the corresponding position of the splash shield to be proportional to the distance from the bottom of the mixing barrel, which can effectively reduce the possibility of paint splashing out of the barrel. Since the paint can only splash out from the surface of the entire paint when splashing, and the paint needs to overcome its own gravity to do work when splashing, this requires the paint to have a certain rotation speed to collide with other objects and generate a sufficiently large force. Due to the setting of splash shields of different thicknesses in the present application, the thicker the thickness of the baffle at the corresponding position of the paint that contacts a higher position, the greater the reaction force that the paint needs to overcome to continue to rotate over the baffle, and the better the effect of slowing down this part of the paint, the possibility of splashing out of the barrel is further reduced.
[0014] Optionally, a plurality of splash-proof assemblies are provided, and a plurality of flow channels are provided.
[0015] By adopting the above-mentioned technical scheme, the present application is provided with a plurality of splash-proof components and flow grooves. Firstly, the increase in the number of splash-proof components can further optimize the deceleration effect, and secondly, the increase in the number of flow grooves can further slightly speed up the coating. The present application increases and adjusts the number of both, which can achieve the best balance between the two effects of fully dispersing the coating and slowing down the coating, further improving the practicality and operability of the present device.
[0016] Optionally, an auxiliary component for stirring the paint is arranged between the splash-proof components.
[0017] By adopting the above-mentioned technical scheme, the present application provides an auxiliary component for stirring the paint between the splash-proof components. The paint is further stirred to a certain extent on the basis of the splash-proof baffle slowing down the paint, thereby avoiding as much as possible the phenomenon of insufficient shearing, crushing and dispersion of the paint due to excessive deceleration, thereby effectively improving the practicality and operability of the device.
[0018] Optionally, the auxiliary component includes a first rotating shaft vertically arranged in the mixing barrel and an auxiliary blade fixedly mounted on the first rotating shaft and rotating with the first rotating shaft.
[0019] By adopting the above-mentioned technical scheme, the present application utilizes the first rotating shaft to drive the auxiliary blades to stir the paint between the splash-proof components, and further stirs the paint to a certain extent on the basis of the splash-proof baffle slowing down the paint, thereby avoiding as much as possible the phenomenon of insufficient shearing, crushing, and dispersion of the paint due to excessive deceleration, thereby effectively improving the practicality and operability of the device.
[0020] Optionally, the stirring assembly includes a second rotating shaft vertically arranged in the stirring barrel and a stirring blade fixedly mounted on the second rotating shaft and rotating with the second rotating shaft.
[0021] By adopting the above technical solution, the present application utilizes the second rotating shaft to drive the stirring blades to stir the paint in the stirring barrel, so that the paint is fully mixed, dissolved, and dispersed, effectively improving the practicality and operability of the device.
[0022] Optionally, a power component for providing power to the stirring component and the auxiliary component is provided in the stirring barrel.
[0023] By adopting the above technical solution, the present application sets up a power component in the mixing barrel to provide power for the mixing component and the auxiliary component, so that all the paint in the mixing barrel is fully mixed, dissolved and dispersed, effectively improving the practicality and operability of the device.
[0024] In summary, this application includes the following beneficial technical effects:
[0025] 1. By setting up a splash-proof component, the present application reduces the rotation speed of the paint without affecting the mixing, dissolution and dispersion of the paint, thereby reducing the magnitude of the relative force generated after the paint collides with the inner wall of the mixing barrel. The splash-proof device in the present application can reduce the possibility of splashing of the paint after being subjected to external force, thereby reducing the waste of paint.

DETAILED DESCRIPTION
[0030] The following is combined with Figure 1-3 This application is described in further detail.
[0031] The embodiment of the present application discloses a splash-proof device for a mixer.
[0032] Reference Figure 1 , Figure 2 A splash-proof device for a mixer includes a mixing barrel 1, a closed cavity 11 is provided at the bottom of the mixing barrel 1, and a power assembly 2 is arranged in the cavity 11. A stirring assembly 3 is arranged at the center position just above the cavity 11, and the stirring assembly 3 includes a second rotating shaft 31 vertically arranged in the mixing barrel 1 and a stirring blade 32 fixedly mounted on the second rotating shaft 31 and rotating with the second rotating shaft 31. The second rotating shaft 31 is fixedly connected to the power assembly 2, and the power assembly 2 provides rotational power for the second rotating shaft 31, driving the stirring blade 32 to rotate, stirring the paint in the mixing barrel 1, so that the paint is fully mixed, dissolved, and dispersed.
[0033] A splash-proof device for a mixer also includes a plurality of splash-proof components 4 uniformly arranged around the inner wall of a mixing barrel 1, the splash-proof components 4 including a sheet-shaped splash-proof baffle 41 welded to the inner wall of the mixing barrel 1, a plurality of flow grooves 42 are provided on the splash-proof baffle 41, through which part of the paint slowed down by the splash-proof baffle 41 can pass, and the paint is slightly accelerated on the basis of the paint being slowed down by the splash-proof baffle 41, so as to avoid as much as possible the phenomenon of insufficient shearing, crushing and dispersion of the paint due to excessive deceleration.
[0034] Reference Figure 2 , Figure 3The splash shield 41 includes a splash shield edge 411 arranged on the side away from the bottom of the mixing barrel 1 and a convergence edge 412 arranged on the side close to the stirring component 3, the convergence edge 412 gradually converges toward the center position of the mixing barrel 1, and the vertical length of the splash shield 41 is greater than the vertical length of the stirring blade 32, and the thickness of the corresponding position of the splash shield 41 is proportional to the distance from the bottom of the mixing barrel 1, and as the relative position of the splash shield 41 is closer to the barrel mouth of the mixing barrel 1, the thickness of the plate is greater.
[0035] An auxiliary component 5 for stirring the paint is arranged between the splash-proof components 4, and the auxiliary component 5 includes a first rotating shaft 51 fixedly connected to the power component 2, and an auxiliary blade 52 rotating with the first rotating shaft 51 is fixedly mounted on the first rotating shaft 51. The paint is stirred to a certain extent on the basis of the paint being decelerated by the splash-proof baffle 41, so as to avoid as much as possible the phenomenon of insufficient shearing, crushing and dispersion of the paint due to excessive deceleration.
[0036] The implementation principle of the splash-proof device for a mixer according to the embodiment of the present application is as follows: first, the paint is put into the mixing barrel 1, the power assembly 2 is turned on, and then the first rotating shaft 51 and the second rotating shaft 31 are driven to rotate. The paint will mainly rotate continuously and fixedly along the first rotating shaft 51 in the rotation direction of the rotating shaft, and the splash-proof assembly 4 fixedly installed on the inner wall of the mixing barrel 1 can reduce the speed of the high-speed rotating paint. Specifically, the splash-proof baffle 41 is used to block part of the paint close to the inner wall of the mixing barrel 1. During its rotation, the splash-proof baffle 41 can reduce the rotation speed of the paint. At the same time, as the convergence edge 412 gradually converges to the center position of the mixing barrel 1, and the thickness of the corresponding position of the splash-proof baffle 41 is The distance from the bottom of the mixing barrel 1 is proportional to the distance. As the relative position of the splash guard plate 41 is closer to the barrel mouth of the mixing barrel 1, the thickness of the plate becomes thicker. Therefore, the closer it is to the paint layer above the mixing barrel 1, the greater the amount of paint that is decelerated inside, and the degree of decrease in the overall speed will be greater than the degree of decrease in the overall speed of the paint layer far away from the top of the mixing barrel 1. In other words, the degree of decrease in the speed of the part of the paint that can splash out of the barrel is greater than that of the paint at other positions, thereby reducing the magnitude of the relative force generated after the paint collides with the inner wall of the mixing barrel 1, so that the splash guard device in the present application can reduce the possibility of splashing of the paint after being subjected to external force, thereby reducing the degree of waste of the paint.
[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
