Description

Technical Field

[0001] The utility model relates to the technical field of cement grinding equipment accessories, in particular to a cement grinding partition plate. Background Art

[0002] As an important building material, cement is widely used in civil construction, water conservancy, national defense and other engineering fields. In its production process, cement mill is the key equipment for further crushing the material after it is crushed. The cement mill mainly drives the medium inside it to move from a low place to a high place through the rotation of the equipment, and then falls from a high place to hit the broken cement material to crush the cement material. The cement mill is equipped with partition plates inside. The partition plates play a vital role in the cement mill. They are used to separate the grinding media, prevent the axial movement of the media, and prevent oversized particles from entering the next bin, which has a direct impact on the grinding effect.

[0003] The partition plate is generally provided with a plurality of corresponding sieve holes, which prevent the axial movement of the medium and prevent oversized particles from entering the next bin. At the same time, the sieve holes can also allow materials that meet the internal through-hole size to pass through the sieve holes smoothly and enter the next bin. However, due to the limited aperture of the sieve holes, during the passage of the material, it is easy for the material to block the sieve holes, affecting the subsequent normal passage of the material and the screening effect. Some partition plates use vibration motors to generate vibrations to promote the unblocking of the blocked sieve holes. However, since the cement mill equipment works in a rotating manner, when a vibration motor is used for vibration operation, the vibration motor also rotates with the partition plate, making it difficult to perform normal wiring operations, so that the vibration anti-blocking operation cannot be performed normally. In view of this, we propose a cement mill partition plate. Utility Model Content

[0025] 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.

[0026] See also Figure 1-Figure 5 The utility model provides a technical solution: a cement mill partition plate, including a partition plate body 1, a plurality of medium blocking components 2 perpendicular to each other with the partition plate body 1 are provided on the partition plate body 1, the medium blocking component 2 includes a central tube 20 fixedly mounted on the partition plate body 1, and end rings 21 are fixedly mounted on both ends of the central tube 20, and the two end rings 21 are respectively located on both sides of the partition plate body 1, and the front end of the end ring 21 located on the front side is fixedly mounted with a front mesh cover 22, and the rear end of the end ring 21 located on the rear side is fixedly mounted with a rear mesh cover 23, both of the front mesh cover 22 and the rear mesh cover 23 are mesh structures, and both of the front mesh cover 22 and the rear mesh cover 23 are conical, so that materials that meet the size can be conveyed through the through holes in the front mesh cover 22 and the rear mesh cover 23;

[0027] Specifically, a ball baffle 25 is fixedly mounted on the inner wall of the end ring 21, and a discharge gap 26 is provided between the ball baffle 25 and the inner wall of the end ring 21. A material cavity 24 is provided in the front mesh cover 22 and the rear mesh cover 23, and a steel ball 28 is provided in the material cavity 24. A plurality of ball pushing plates 27 arranged in a ring shape and at equal intervals are fixedly mounted on the cavity wall of the material cavity 24, so that the steel balls 28 are pushed to a mid-air position in the material cavity 24 and fall therefrom by using the ball pushing plates 27. As the steel balls 28 fall onto the front mesh cover 22 and the rear mesh cover 23, the front mesh cover 22 and the rear mesh cover 23 can be vibrated, and after the vibration is generated, the material blockage in the front mesh cover 22 and the rear mesh cover 23 can be avoided.

[0028] In this embodiment, the front end of the front mesh cover 22 is located on the horizontal symmetry axis of the front mesh cover 22, and the rear end of the rear mesh cover 23 is located below the horizontal symmetry axis of the rear mesh cover 23, so that the material can enter along the front mesh cover 22 and fall out from the through hole in the rear mesh cover 23 more smoothly.

[0029] Specifically, the ball baffle plate 25 is provided with a plurality of through holes 251 connected to the outside world. The outer diameter of the steel ball 28 is greater than the height of the discharge gap 26. A ball baffle rod 261 is fixedly installed between the left and right cavity walls of the discharge gap 26. The ball baffle rod 261 blocks the rear side of the steel ball 28 to achieve the effect of blocking the steel ball 28 and prevent the steel ball 28 from falling into the center tube 20.

[0030] Furthermore, the end of the ball pushing plate 27 extends to the end ring 21, and the number of the ball pushing plates 27 is 2 to 4, so that the steel ball 28 is driven by the ball pushing plate 27 to move to a suitable height and drop.

[0031] In addition, an anti-sticking smooth layer 201 is provided on the inner wall of the central tube 20. The anti-sticking smooth layer 201 can be made of inorganic nano-silicon material. The inorganic nano-silicon material is not easy to adhere to other materials, which is beneficial to reducing the adsorption force between the material and the material, so that the material is not easy to adhere when passing through the central tube 20.

[0032] It is worth noting that a plurality of bolt fixing holes 10 arranged in a ring shape and at equal intervals are provided on the annular side surface of the partition plate body 1, so as to facilitate the fixed installation of the partition plate body 1 on the frame of the external cement mill to complete the fixed installation operation.

[0033] It is worth noting that material blocking rubber patches 11 are fixedly installed on the front and rear side surfaces of the partition plate body 1. The material blocking rubber patches 11 are fixedly installed on the inner wall of the cement mill to prevent materials from getting stuck between the partition plate body 1 and the inner wall of the cement mill.

[0034] When the cement mill partition plate of the present invention is in use, the partition plate body 1 and the material blocking rubber patch 11 are fixedly installed on the inner wall of the cylinder of the cement mill. As the cylinder of the cement mill rotates, it can drive the partition plate body 1 and the medium blocking assembly 2 to rotate. After the medium blocking assembly 2 rotates, the ball pushing plate 27 in each medium blocking assembly 2 can push the steel ball 28 from the bottom position to the mid-air position in the material chamber 24. As the medium blocking assembly 2 continues to rotate, the ball pushing plate 27 no longer blocks the steel ball 28. At this time, the steel ball 28 at the corresponding height can fall from the air. The steel ball 28 falling from the air can fall on the front mesh cover 22 and the rear mesh cover 23, causing the front mesh cover 22 and the rear mesh cover 23 to vibrate. After the vibration is generated, it can avoid material blockage in the front mesh cover 22 and the rear mesh cover 23, so that the material can pass through the through-hole parts in the front mesh cover 22 and the rear mesh cover 23 more smoothly.

[0035] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention.
