DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In the present application, unless otherwise clearly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0033] The present application embodiment discloses a stirring barrel for stirring and adding an auxiliary agent. Figure 1 A mixing barrel 1 for stirring and adding an auxiliary agent comprises a mixing barrel 1, the upper end of which is open, and a sealing cover 11 which can completely cover the open end of the mixing barrel 1 is clamped at the open end of the mixing barrel 1. The sealing cover 11 is arranged to prevent auxiliary agent powder from splashing when stirring is performed in the mixing barrel 1, thereby polluting the working environment.

[0034] refer to Figure 2Two baffles 2 are fixed on the inner wall of the mixing barrel 1. Both baffles 2 are arranged in the horizontal direction. The two baffles 2 are distributed in parallel on the inner wall of the mixing barrel 1. The baffle 2 is a rectangular plate-like structure with a circular length direction. The upper side of the baffle 2 is connected to the inner wall of the mixing barrel 1, and the lower side freely extends to the center of the mixing barrel 1, so that the baffle 2 is inclined along the inner wall of the mixing barrel 1. The inclined baffle 2 can better guide the flow of the powdered auxiliary agent, so that the flow direction of the powdered auxiliary agent will change when passing through the baffle 2, thereby increasing turbulent motion. One or more notches 21 are arranged on the baffle 2. The notch 21 can be rectangular, circular or other shapes. In the embodiment of the present application, the notch 21 is opened as a rectangular shape. During the stirring process, the powdered auxiliary agent can change its flow direction and speed when passing through the baffle 2 with the notch 21, effectively improving the stirring effect, so that the powder material and the auxiliary agent can be more fully mixed. At the same time, the width of the notch 21 accounts for 5%-20% of the circumference of the baffle 2. The setting of this ratio range can ensure the structural strength of the baffle 2 while effectively changing the flow state of the fluid, thereby avoiding the gap 21 being too large to cause insufficient structural strength of the baffle 2 or the gap 21 being too small to affect the stirring and mixing effect.

[0035] refer to Figure 2 , a stirring assembly 3 is also provided in the stirring barrel 1, and the stirring assembly 3 includes a stirring shaft 31 and two groups of stirring blades 32. The stirring shaft 31 is coaxially connected to the stirring barrel 1, and a driving motor 5 is fixedly connected to the lower end of the stirring barrel 1. The output shaft of the driving motor 5 is vertically upwardly penetrated through the bottom surface of the stirring barrel 1 and coaxially fixed to the lower end of the stirring shaft 31, and the driving motor 5 drives the stirring shaft 31 to rotate in the stirring barrel 1. Two groups of sliders 311 are fixedly provided on the circumference of the stirring shaft 31, and the two groups of sliders 311 are arranged in an array along the axial direction of the stirring shaft 31, and each group of sliders 311 includes two sliders, and the two sliders 311 of each group are arranged on both sides of the stirring shaft 31 along the radial direction of the stirring shaft 31. Each group of stirring blades 32 includes a connecting portion 321 and four stirring blades 322, and the connecting portion 321 is columnar, and a through hole is opened at the end of the connecting portion 321, and the connecting portion 321 can be coaxially sleeved on the stirring shaft 31 through the through hole. The stirring blades 322 are fixedly connected to the circumferential surface of the connecting portion 321 , and the stirring blades 322 are arranged in an array along the circumferential direction of the connecting portion 321 .

[0036] refer to Figure 2 and 3, a slide groove is provided at the position corresponding to the slider 311 on the inner circumferential surface of the connecting portion 321, and the width of the slide groove is greater than or equal to the width of the slider 311, so that the slider 311 can slide in the slide groove. The slide groove includes a clamping section 3212 and a mounting section 3211 that are connected to each other. The mounting section 3211 is opened along the axial direction of the connecting portion 321, and both ends of the mounting section 3211 are penetrated through the two ends of the connecting portion 321 along the axial direction. The clamping section 3212 is L-shaped, and the two sections of the clamping section 3212 are arranged perpendicular to each other. One section of the clamping section 3212 is horizontally arranged and connected to the mounting section 3211, and the other section is opened vertically upward in parallel with the mounting section 3211. The clamping section 3212 is located on the opposite side of the mounting section 3211 connected thereto in the direction of rotation of the stirring shaft 31.

[0037] When the stirring fan blade 32 is sleeved on the stirring shaft 31, the sliding block 311 enters the mounting section 3211 and slides along the length direction of the mounting section 3211. When the sliding block 311 moves to the connection position of the mounting section 3211 and the clamping section 3212, the connecting portion 321 is rotated counterclockwise to make the sliding block 311 enter the clamping section 3212 and slide in the direction away from the mounting section 3211; the side wall of the sliding block 311 abuts against the clamping section 3212, and the rotating portion cannot continue to rotate due to resistance, so the connecting portion 321 is released, and the connecting portion 321 moves downward under the action of gravity, so that the sliding block 311 enters the clamping section 3212 set in the vertical direction, so that the stirring fan blade 32 is connected to the stirring shaft 31 and rotates synchronously with the stirring shaft 31 driven by the driving motor 5 in the clockwise direction.

[0038] refer to Figure 2 The shape of the stirring blade 322 can be one or more of a straight blade, an oblique blade or a curved blade. The stirring blades 322 of different shapes can adapt to different stirring needs. For example, the straight blade stirring blade 322 is suitable for general stirring needs, while the oblique blade blade is at a certain angle to the axis, which can generate strong centripetal force and eddy current, which is conducive to improving the mixing efficiency, and is particularly effective for crushing and dispersing harder or stickier materials. The curved blade blade is S-shaped, which can form shear force and extrusion force to effectively grind and mix the material. Its curved surface design can also cause local compression and distortion of the material, thereby providing more opportunities for interaction, which is suitable for occasions requiring higher stirring effects.

[0039] refer to Figure 2 A discharge port 4 is also provided at the bottom of the mixing barrel 1. When the mixing is completed, the valve of the discharge port 4 is opened to discharge the mixed material. This arrangement can facilitate the loading and unloading of materials and improve production efficiency.

[0040] refer to Figure 2The baffle 2 is made of wear-resistant material. Wear-resistant material can extend the service life of the baffle 2 and reduce maintenance costs. For example, wear-resistant materials such as stainless steel and ceramics can be used to make the baffle 2.

[0041] The implementation principle of a stirring barrel 1 for stirring and adding an auxiliary agent in the embodiment of the present application is:

[0042] Open the sealing cover 11. Because different shapes of stirring blades 32 will produce different flow fields and mixing effects when processing powdered materials, select the appropriate shape of the stirring blade 322 according to the specific mixing requirements. The selected stirring blades 32 are sleeved on the stirring shaft 31 from top to bottom in sequence. The stirring blades 32 to be installed below the stirring shaft 31 are first aligned with a group of sliders 311 located above, and the stirring blades 32 are moved in the vertical direction so that a group of sliders 311 located above pass through the installation section 3211 of the stirring blades 32, and the stirring blades 32 are located between the two groups of sliders 311. Then, the sliding groove of the stirring blades 32 to be installed below the stirring shaft 31 is aligned with a group of sliders 311 located below, and the stirring blades 32 are moved downward and rotated counterclockwise so that the slider 311 slides into the clamping section 3212. Release the stirring blades 32, and under the action of gravity, the slider 311 enters a section vertically set upward in the clamping section 3212 to complete the installation. Then, another stirring blade 32 is installed in the upper set of sliders 311. The powdered additive to be mixed is added into the stirring barrel 1, the sealing cover 11 is covered, and the driving motor 5 is started. The driving motor 5 drives the stirring shaft 31 to rotate in a clockwise direction, thereby driving the stirring blade 32 to stir and mix the additive. The additive is mixed evenly under the action of the baffle 2 with the notch 21 and the stirring blade 32, achieving efficient stirring effect and high-quality mixing quality.

[0043] 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.
