Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to a material discharge mechanism for a ceramic ball mill. Background Art

[0002] Ball mills are widely used in industrial processing. Bearings and other mechanical equipment require very high-precision bearing balls, which require the diameters of the balls to be equal and the surface of the balls to be flat and smooth.

[0003] After searching, it was found that the Chinese utility model patent with authorization publication number CN210878995U discloses an automatic discharging ceramic ball grinding machine. According to its description, a ceramic ball grinding environment is formed by setting a conical lower mold and an upper mold with a conical surface at the bottom. The lower mold is driven by a rotating motor to rotate to achieve relative rotation between the upper mold and the lower mold, thereby grinding the ceramic balls. From top to bottom, the gap between the upper mold and the lower mold continues to shrink. When the diameter of the ceramic ball is smaller than the bottom gap, the product automatically separates from the upper and lower molds and enters the collection tank through the slide groove and the product channel, thereby realizing automatic discharging.

[0004] However, the ball grinding machine in the above patent has the following problems: the ceramic balls after grinding are directly discharged through the chute, but the dust or debris attached to the surface of the ceramic balls after grinding are also discharged, affecting the subsequent processing of the ceramic balls. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides a ceramic ball mill unloading mechanism to solve the problems mentioned in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A ceramic ball mill discharge mechanism includes a cylinder, the upper end of the cylinder is fixedly connected to a conical top cover, the top cover is provided with a spiral discharge channel, the outer wall of the top cover is provided with a plurality of through holes connected to the discharge channel, the lower end of the discharge channel is connected to an outwardly extending discharge channel, the end of the discharge channel is provided with a blocking mechanism, and a dust suction mechanism is provided in the cylinder, which sucks dust in the discharge channel into the top cover through the dust suction mechanism.

[0008] Preferably, a transparent cover is connected to the top of the discharge channel, a feed port is provided at the upper end of the discharge channel, and a discharge port connected to the discharge channel is provided at the lower end.

[0009] Preferably, the material blocking mechanism includes an L-shaped frame installed on the bottom surface of the discharge channel, a cylinder installed on the L-shaped frame, and a baffle connected to the telescopic end of the cylinder. The end of the discharge channel is provided with an opening, and the baffle is slidably arranged in the opening.

[0010] Preferably, the upper end of the cylinder body is connected to a fixing block, the top surface of the fixing block is provided with a bucket-shaped groove, and the center of the groove is connected to a dust suction pipe.

[0011] Preferably, the dust collection mechanism includes an induced draft fan installed in the cylinder, the inlet end of the induced draft fan is connected to the dust collection pipe, and the outlet end of the induced draft fan is connected to the dust exhaust pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] After grinding, the ceramic balls enter from the upper end of the discharge channel and roll downward along the spiral discharge channel. During the rolling process, the dust on the surface of the ceramic balls will fall and fly in the discharge channel. At this time, the flying dust can be sucked from the through hole through the dust suction mechanism, so that the dust on the surface of the ceramic balls can be cleaned during the transportation process, which improves the efficiency of dust cleaning and is beneficial to the subsequent processing of the ceramic balls.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1

[0021] See also Figure 1-Figure 3A ceramic ball mill discharge mechanism includes a cylinder 1, a conical top cover 2 fixedly connected to the upper end of the cylinder 1, a spiral discharge channel 4 provided on the top cover 2, a plurality of through holes 3 provided on the outer wall of the top cover 2 communicating with the discharge channel, and an outwardly extending discharge channel 5 connected to the lower end of the discharge channel 4. The upper end of the discharge channel 4 is provided with a feed port 7, and the lower end is provided with a discharge port communicating with the discharge channel 5; a material blocking mechanism is provided at the end of the discharge channel 5, and a dust suction mechanism is provided within the cylinder 1, which sucks dust from the discharge channel 4 into the top cover through the dust suction mechanism. The upper end of the cylinder 1 is connected to a fixed block 11, the top surface of the fixed block 11 being provided with a bucket-shaped groove 12, and the center of the groove 12 is connected to a dust suction pipe 13.

[0022] The dust collection mechanism includes an induced draft fan 14 mounted within the cylinder. The inlet end of the induced draft fan 14 is connected to the dust collection pipe 13, and the outlet end of the induced draft fan 14 is connected to the dust exhaust pipe 15. After grinding, the ceramic balls enter the feeding channel 4 through the feed port 7 and roll downward along the spiral feeding channel 4. During this rolling process, the ceramic balls will drop dust on their surfaces and fly into the feeding channel 4. At this time, the induced draft fan 14 is activated to suck the flying dust into the through hole 3. This allows the ceramic balls to be cleaned of dust during transportation, improving the efficiency of dust cleaning and facilitating the subsequent processing of the ceramic balls.

[0023] The material blocking mechanism includes an L-shaped frame 8 mounted on the bottom surface of the discharge channel, a cylinder 9 mounted on the L-shaped frame, and a baffle 10 connected to the telescopic end of the cylinder. The end of the discharge channel 5 is provided with an opening, and the baffle 10 slides into the opening. As the ceramic balls slide down, the baffle 10 blocks them, allowing them to slide out one by one in an orderly manner.

[0024] Example 2

[0025] On the basis of Example 1, a transparent cover plate 6 is connected to the top of the feeding channel 4. The cover plate can prevent dust on the surface of the ceramic ball from overflowing.
