Compressed air of 0.6MPa to 0.8MPa is introduced into the air holes through the air source distribution chamber to form a strong airflow field around the maze, so that large particles cannot enter the classifier and the particle size of the classified materials is narrower. However, this micro powder classifier lacks a dispersion device at the feed inlet, which easily leads to agglomeration of micro powders, and the uniformity of material classification is difficult to ensure. At the same time, the dispersion mechanism needs to ensure closedness to avoid dust pollution and safety risks for operators.

[0004] In view of the above problems, a micro powder classifier with a dispersing function is proposed. Utility Model Content

At the same time, the dispersing mechanism needs to ensure the sealing to avoid dust pollution and safety risks for operators.

[0015] 1. The utility model provides a micro powder classifier with a dispersing function. Through the matching arrangement of a fixed support mechanism and a conical grading filter, a rotating wheel drives the grading mechanism to rotate. The rotating wheel has a small radius and a large wheel ring radius, so that the wheel ring and the conical grading filter can rotate slowly.

[0016] 2. The utility model provides a micro powder classifier with a dispersing function. Through the matching arrangement of a feeding mechanism and a grading mechanism, since the conical block is in a fixed state, the movement of the conical grading filter can drive the micro powder to be ground and dispersed by the conical block to prevent agglomeration. A circular closed cover can be provided on the inlet side of the opening frame to ensure the closure of the dispersing mechanism. The grading mechanism is tilted so that the powder can move downward under the action of gravity to achieve grading.

At the same time, the dispersing mechanism needs to ensure closure to avoid dust pollution and safety risks for operators. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] 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 in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0025] Combination Figure 1 The utility model is a micro powder classifier with a dispersing function, comprising a fixed support mechanism 1, a feeding mechanism 2 for dispersing and grinding powder is fixedly arranged on the upper end of the fixed support mechanism 1, a grading mechanism 3 for grading and screening is rotatably arranged on one side of the fixed support mechanism 1, the fixed support mechanism 1 comprises a rotating wheel 13 which is rotatably arranged, the feeding mechanism 2 comprises a grading guide frame 21 and an opening frame 22 which are fixedly connected to the fixed support mechanism 1, the opening frame 22 comprises a conical block 223 which is embedded in the grading mechanism 3, the grading mechanism 3 comprises a wheel ring 31 which is meshed with the rotating wheel 13, and a conical grading filter 32 which is fixedly connected to the wheel ring 31.

[0026] Specifically, the fixed support mechanism 1 fixes the grading guide frame 21 and the opening frame 22, and the rotating wheel 13 drives the grading mechanism 3 to rotate. The radius of the rotating wheel 13 is small, and the radius of the wheel ring 31 is large, so that the wheel ring 31 and the conical grading filter 32 can rotate slowly. The rotating grading setting of the conical grading filter 32 makes the micro-powder built in the conical grading filter 32 move continuously and disperse to achieve grading. At the same time, the conical grading filter 32 and the conical block 223 are matched. Since the conical block 223 is in a fixed state, the movement of the conical grading filter 32 can drive the micro-powder to be ground and dispersed by the conical block 223 to prevent agglomeration. A circular closed cover can be set on the inlet side of the opening frame 22 to ensure the closure of the dispersion mechanism. The grading mechanism 3 is tilted so that the powder can move downward under the action of gravity to achieve grading. The slow rotation of the grading mechanism 3 prevents excessive dust from affecting the grading effect.

[0027] The utility model is further described below in conjunction with embodiments.

[0030] The rotating wheel 13 includes a support frame 131 connected to the upper end of the base frame 11, a gear 132 is rotatably connected in the support frame 131, the support frame 131 supports the gear 132, a group of gears 132 are connected to the output end of the driving motor 12, and the gear 132 and the wheel ring 31 are meshed with each other to drive the grading mechanism 3 to rotate slowly.

[0031] There are three groups of grading guide frames 21, and a discharge pipe 211 is provided at the lower end of the grading guide frame 21. The three groups of grading guide frames 21 arranged side by side are respectively used to collect powders of different sizes. The discharge pipe 211 is arranged at the lower end to realize powder output under the action of gravity.

[0032] The opening frame 22 includes a locking frame 221 arranged inside the movable locking wheel ring 31. The locking frame 221 is arranged as an oblique opening. The outer end of the locking frame 221 is arranged with a circle. The oblique setting of the locking frame 221 facilitates the powder to enter the grading mechanism 3. The circular setting at the outer end of the locking frame 221 facilitates the socketing of the round cover. The grading guide frame 21 is tilted as a whole with the grading mechanism 3, which can prevent the round cover from falling and keep the grading environment closed.

[0033] The opening frame 22 further comprises a connecting frame 222 fixedly connected to the locking frame 221, one end of the connecting frame 222 is connected to a conical block 223, the connecting frame 222 fixes the conical block 223, and the conical setting of the conical block 223 enables the powder to be dispersed to the side.

[0034] Embodiment 2:

[0035] Combination Figure 3 and Figure 5 The grading mechanism 3 also includes a guide pipe 34 connected to one end of the conical grading filter 32. The outer end of the guide pipe 34 is connected to the bracket 33. The guide pipe 34 is set on one side to discharge larger waste residues. The outer side of the bracket 33 is sleeved with a wheel ring 31, so that the entire grading mechanism 3 can rotate synchronously.

[0036] The conical grading filter 32 is provided with small holes 321, medium holes 322 and large holes 323 in different areas.

The small holes 321 are located on the side with a larger area so that fine particles in the powder can be filtered to the greatest extent. At the same time, the conical setting facilitates the concentration of materials while filtering, preventing the materials from being too dispersed during grading, which is not convenient for the final unified collection.
