Description

Technical Field

[0001] This utility model relates to the field of ring roller mill equipment, specifically to a grading mechanism for ring roller mill equipment. Background Technology

[0002] Ring roller mills are high-efficiency grinding equipment widely used in mining, metallurgy, chemical, and building materials industries. The grinding wheels and grinding rings of ring roller mills are made of high-quality alloy materials, which have good wear resistance and long service life. The working principle of ring roller mills is to feed materials into the gap between the grinding wheels and grinding rings. Through the impact, extrusion and grinding of the grinding wheels and grinding rings, the materials are ground into powder.

[0003] After the ring roller mill finishes grinding the material, due to the difference in particle size, the powder needs to be classified by a grading mechanism before use to meet the needs of different applications.

[0004] Existing grading mechanisms have the following drawbacks: they cannot enable powder to be screened quickly and thoroughly, powder tends to accumulate in large quantities, reducing screening efficiency, and they cannot quickly and thoroughly complete the grading and screening of powder.

[0005] The purpose of this invention is to design a grading mechanism for a ring roller mill to address the problems existing in the prior art. Utility Model Content

[0006] In view of the problems existing in the prior art, the present invention provides a grading mechanism for a ring roller mill, which can effectively solve at least one of the problems existing in the prior art.

[0007] The technical solution of this utility model is:

[0008] A classifying mechanism for a ring roller mill includes:

[0009] A loading container is provided with a conveying device at the top of the loading container. The conveying device is used to periodically transport the powder crushed by the ring roller mill into the loading container so that the powder falls onto the uppermost screening screen.

[0010] Several limiting splash guards are arranged longitudinally side by side inside the load-bearing box, and the inner diameter of the several limiting splash guards increases from top to bottom;

[0011] Several screening screens are horizontally arranged at the bottom end of each of the limiting splash guards, and the mesh size of the screening screens increases sequentially from top to bottom;

[0012] A plurality of multi-abutment screens are provided, which are elliptical and disposed within the load-bearing box and located below the screening screen. When driven, the plurality of multi-abutment screens reciprocate upward and downward. The multi-abutment screens are used to rise a predetermined vertical distance when driven to simultaneously abut multiple positions on the bottom surface of the screening screen. The plurality of multi-abutment screens are connected to the load-bearing box via a common driving component, which is used to drive the plurality of multi-abutment screens to operate simultaneously.

[0013] The surface of the loading and placement box is rotatably equipped with a material handling door;

[0014] Several loading and unloading components are disposed between the limiting splash guard and the load-bearing box.

[0015] Furthermore, the conveying device includes a suction pump disposed on the top surface of the container, the inlet of the suction pump being connected to a suction pipe; and a conveying pipe, one end of which is connected to the outlet of the suction pump, the other end of which extends into the container, and the other end of which is located above the uppermost screening screen.

[0016] Furthermore, the multi-adjustment screen frame includes an annular tube, which is vertically mounted inside the load-bearing box and located below the screening screen. Several protrusions are provided at the top of the annular tube.

[0017] Furthermore, the boss is adjusted at the top of the annular tube via a threaded rod.

[0018] Furthermore, the driving component includes an upper connecting plate disposed above the outer surface of the load-bearing box, a lower connecting plate disposed below the outer surface of the load-bearing box, a rotating motor disposed on the upper connecting plate, the lower connecting plate and the rotating motor connected by a screw, a plurality of lifting blocks disposed on the screw, two guide posts disposed between the lower connecting plate and the upper connecting plate, the guide posts passing through the lifting blocks; a plurality of linkage rods, one end of each linkage rod disposed on the lifting block, the other end of each linkage rod passing through the load-bearing box and connected to the multi-adjustment screen frame, and clearance holes disposed on the load-bearing box and outside the linkage rods.

[0019] Furthermore, the loading and unloading component includes bolts, which are disposed between the limiting splash guard and the load-bearing container.

[0020] Furthermore, the limiting splash guard is an ultra-high molecular weight polyethylene plate used to reduce powder adhesion to the inner wall.

[0021] Therefore, the present invention provides the following effects and / or advantages:

[0022] 1) The load-bearing box has a predetermined accommodating space, the load-bearing box is used to support the components, and the load-bearing box is used to stably place the grading mechanism on the ground;

[0023] The conveying device is used to periodically transport the powder crushed by the ring roller mill to the container box so that the powder falls onto the uppermost screening screen.

[0024] Several of the aforementioned multi-abutment screen frames are used to reciprocate upward and downward when driven. The multi-abutment screen frames are used to rise a predetermined vertical distance when driven to simultaneously abut multiple positions on the bottom end face of the screening screen, so that the powder on the screening screen is quickly and fully screened by the screening screen, and the powder is not prone to accumulate in large quantities, thus reducing the screening efficiency. This allows several screening screens to quickly and fully complete the grading and screening of the powder.

[0025] The same driving component is used to drive several of the multi-abutment screen frames to operate simultaneously. The limiting anti-splash ring plate is used to prevent powder from splashing everywhere when the multi-abutment screen frames simultaneously abut against multiple positions on the bottom end face of the screening screen. The limiting anti-splash ring plate is used to limit the incoming powder so that the powder is on the screening screen. The material receiving gate is used to be driven to open after several screening screens have completed the grading and screening of the powder.

[0026] The loading and unloading components are operated after the material gate is opened to separate the limiting splash guard from the loading box, thereby removing the graded powder.

[0027] In summary, this method enables powder to be screened quickly and thoroughly, preventing powder from accumulating in large quantities and reducing screening efficiency, and allowing for rapid and thorough grading and screening of powder.

[0028] 2) The protrusion is adjusted at the top of the annular tube by a threaded rod to adjust the vertical position of the protrusion at the top of the annular tube, thereby meeting the resistance requirements of the corresponding screening screen and adjusting the screening speed of the corresponding screening screen for the powder of the grade.

[0029] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention are realized and obtained through the structures particularly pointed out in the description and the drawings.

[0040] Several limiting anti-splash ring plates 2 are arranged longitudinally side by side in the container box 1. The inner diameter of the several limiting anti-splash ring plates 2 increases from top to bottom. The limiting anti-splash ring plates 2 are used to prevent powder from splashing everywhere when multiple screen frames simultaneously abut against multiple positions on the bottom end face of the screening screen 3.
