Description

Technical Field

[0001] This utility model relates to the field of ceramic production, and in particular to a ball mill screening machine for ceramic preparation. Background Technology

[0002] The ball mill screening machine for ceramic preparation is a piece of equipment that integrates ball milling and screening functions. It is widely used in the processing of ceramic raw materials. The ball milling section rotates the cylinder to drive the grinding media to impact and grind the raw materials. Then, the screening section classifies and screens the ball-milled materials. Fine powder that meets the requirements is discharged through the screen, while coarse particles are returned to the ball mill for further grinding.

[0003] According to the patent document with publication number CN222384947U, the patent document describes a process where a drive motor rotates the ceramic ball mill body to grind raw materials. The ground material enters the filter plate above the collection box through the discharge port for filtration. Larger particles are scraped by a scraper and enter the conveying pipe. The larger particles are then conveyed by a conveying auger and then enter the feed hopper through the discharge pipe for further grinding.

[0004] The patent document states that during the grinding process of raw materials by the grinding media inside the ceramic ball mill body, the raw materials tend to accumulate in local areas and cannot be fully mixed with the grinding media, affecting the uniformity of grinding. Furthermore, the ground raw materials and unground raw materials tend to mix together due to inertia, resulting in the ground raw materials not being discharged in time, causing over-grinding. Utility Model Content

[0005] The purpose of this invention is to provide a ball mill screening machine for ceramic preparation in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A ball mill screening machine for ceramic preparation includes a processing barrel and a rotating shaft. The rotating shaft is rotatably connected inside the processing barrel, and a screening barrel is slidably connected to the outside of the rotating shaft. A connecting plate is provided on one side of the screening barrel, and two guide rods for driving the screening barrel to rotate are fixed on the other side of the connecting plate. A spring is fixed between the connecting plate and the screening barrel. An inclined plate is provided on the other side of the screening barrel, and a slide rod that is slidably connected to the inclined plate is fixed on the edge of the other side of the screening barrel. An annular groove that cooperates with the slide rod is opened on the side of the inclined plate near the screening barrel.

[0008] Preferably, the processing tank has a feed inlet at the top and a discharge outlet at the bottom.

[0009] Preferably, a motor is fixedly installed at the input end of the rotating shaft.

[0010] Preferred: A lid is inserted into the top of the screening bin, and a handle is fixed to the top of the lid.

[0011] Preferably, the connecting plate is fixed to one end of the rotating shaft, and the spring is sleeved on the outside of the rotating shaft.

[0012] Preferably, both guide rods are slidably connected to the screening bucket, and the ends of the two guide rods away from the connecting plate are inserted into the screening bucket.

[0013] Preferably, the inclined plate is fixedly connected inside the processing tank, and the inclined plate has a circular hole for the rotating shaft to pass through.

[0014] The beneficial effects compared with the existing technology are as follows: the rotation of the shaft drives the connecting plate and two guide rods to rotate, which in turn drives the screening barrel to rotate, thereby causing the slide bar to slide along the annular groove on the inclined plate. Then, the spring is compressed and rebounds, causing the screening barrel to move back and forth along both sides of the shaft. The grinding media and ceramic materials change positions, and the grinding media and ceramic materials are mixed more thoroughly, improving the uniformity of grinding. Ceramic materials with qualified size can be discharged more quickly, avoiding over-grinding and improving the grinding effect. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-7 As shown, a ball mill screening machine for ceramic preparation includes a processing tank 1 and a rotating shaft 2.

[0028] In this embodiment: A rotating shaft 2 is rotatably connected inside the processing tank 1. A screening tank 4 is slidably connected to the outside of the rotating shaft 2. A connecting plate 6 is provided on one side of the screening tank 4. Two guide rods 7 for driving the screening tank 4 to rotate are fixed on the other side of the connecting plate 6. A spring 8 is fixed between the connecting plate 6 and the screening tank 4. An inclined plate 9 is provided on the other side of the screening tank 4. A sliding rod 10 that is slidably connected to the inclined plate 9 is fixed on the edge of the other side of the screening tank 4. An annular groove that cooperates with the sliding rod 10 is opened on the side of the inclined plate 9 near the screening tank 4. The rotating shaft 2 drives the connecting plate 6 to rotate, thereby driving the screening tank 4 to rotate. The two guide rods 7 rotate, thereby driving the screening barrel 4 to rotate. This causes the grinding media inside the screening barrel 4 to collide with the ceramic material under the action of centrifugal force and inertial force, thus breaking large ceramic particles into smaller particles. The rotation of the screening barrel 4 drives the slide rod 10 to rotate, and the slide rod 10 slides along the annular groove on the inclined plate 9, thereby pushing the screening barrel 4 to move from one side to the other along the rotating shaft 2. After the spring 8 is compressed, its reaction rebound pushes the screening barrel 4 to move from one side to the other along the rotating shaft 2 to reset, thus changing the position of the grinding media and ceramic material inside the screening barrel 4.

[0029] In this embodiment: the top of the processing tank 1 is provided with a feed inlet 11 and the bottom of the processing tank 1 is provided with a discharge outlet 12. Grinding media and ceramic materials are fed into the screening tank 4 through the feed inlet 11 and the ground and screened ceramic materials are discharged through the discharge outlet 12.

[0030] In this embodiment, a motor 3 is fixedly installed at the input end of the rotating shaft 2, and the rotating shaft 2 is driven to rotate by the motor 3.

[0031] In this embodiment: a lid 5 is inserted into the top of the screening barrel 4, and a handle is fixed to the top of the lid 5. By pulling the handle, the lid 5 is pulled out from the top of the screening barrel 4, so that the grinding media and ceramic materials can enter the screening barrel 4.

[0032] In this embodiment: the connecting plate 6 is fixed to one end of the rotating shaft 2, and the spring 8 is sleeved on the outside of the rotating shaft 2. The rotating shaft 2 drives the connecting plate 6 to rotate.

[0033] In this embodiment: both guide rods 7 are slidably connected to the screening bucket 4, and the ends of the two guide rods 7 away from the connecting plate 6 are inserted into the screening bucket 4. The rotation of the connecting plate 6 drives the two guide rods 7 to rotate around the axis of the rotating shaft 2, thereby driving the screening bucket 4 to rotate.

[0034] In this embodiment: the inclined plate 9 is fixedly connected inside the processing barrel 1. The inclined plate 9 has a circular hole for the rotating shaft 2 to pass through. The inclined plate 9 is supported and fixed by the processing barrel 1, and the rotating shaft 2 can rotate through the circular hole.

[0035] Working principle: Pull the handle to remove the lid 5 from the top of the screening barrel 4, and put the grinding media and ceramic materials into the screening barrel 4 through the feed port 11. Then insert the lid 5 into the top of the screening barrel 4. The motor 3 drives the rotating shaft 2 to rotate. The rotation of the rotating shaft 2 drives the connecting plate 6 to rotate, which in turn drives the two guide rods 7 to rotate, thereby driving the screening barrel 4 to rotate. This causes the grinding media in the screening barrel 4 to collide with the ceramic materials under the action of centrifugal force and inertial force, thereby breaking the large ceramic materials into smaller particles. The ceramic materials with qualified size are discharged from the discharge port 12 after passing through the screening barrel 4, while the ceramic materials with unqualified size continue to be ground in the screening barrel 4.

[0036] During this process, the rotation of the screening barrel 4 drives the slide bar 10 to rotate, and then the slide bar 10 slides along the annular groove on the inclined plate 9. The slide bar 10 moves from the top to the bottom of the inclined plate 9, thereby pushing the screening barrel 4 to move from one side to the other along the rotating shaft 2. After the spring 8 is compressed, the reaction rebound pushes the screening barrel 4 to move from one side to the other along the rotating shaft 2 to reset. The slide bar 10 moves from the bottom to the top of the inclined plate 9, so that the grinding media and ceramic materials in the screening barrel 4 change positions, and thus the cycle repeats.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
