Description

Technical Field

[0001] The present application relates to the technical field of retaining rings, and in particular to a novel retaining ring for a vertical mill. Background Art

[0002] The statements in this section merely provide background technical information related to the present application and do not necessarily constitute prior art.

[0003] Slag powder is a byproduct of cement production - slag, which is formed into ultra-fine powder after grinding. It is mainly composed of minerals such as silicate, aluminate, calcium and magnesium. In the preparation process of slag powder, the raw materials need to be crushed in large quantities by a vertical mill. However, during the operation of the vertical mill, the retaining ring of the vertical mill is easily hit by the raw materials and is a consumable part. If damaged, it will affect the grinding efficiency and grinding quality of the vertical mill.

[0004] Patent authorization announcement No. CN210585202U discloses a new type of retaining ring for vertical mill that is easy to adjust in height. By combining the abrasive plate and the retaining assembly into one design, the supporting strength of the retaining plate can be increased. However, the abrasive plate is also combined in sections, which will reduce the supporting strength of the abrasive plate. Since the raw material is crushed between the abrasive plate and the grinding head, the grinding head presses the raw material on the abrasive plate. This combined abrasive plate is prone to breakage at the connection, which in turn causes the abrasive plate to leak material, affecting the use of the vertical mill, and the abrasive plate needs to be replaced. Therefore, a retaining ring that can be used for a long time and prevents damage to the abrasive plate is needed. Utility Model Content

[0005] In order to solve the above problems, the present application proposes a new type of retaining ring for a vertical mill.

[0006] The purpose of the present application is to provide a new type of material retaining ring for a vertical mill. By designing the abrasive plate as an integral structure and fixing the material retaining plate to the abrasive plate through a connecting plate, the material retaining effect of the material retaining plate can be ensured while improving the overall strength of the abrasive plate and preventing damage to the abrasive plate.

[0007] In order to achieve the above purpose, this application adopts the following technical solutions:

[0008] A novel material baffle ring for a vertical mill comprises: a grinding plate, a connecting plate and a material baffle plate. The connecting plate and the grinding plate are perpendicular to each other and fixedly connected. There are four material baffle plates, which are connected end to end to form an annular material baffle coil. The material baffle plate and the connecting plate are detachably connected.

[0009] Furthermore, connecting hooks are provided at both ends of the baffle plates, and adjacent baffle plates are connected by the connecting hooks. The connecting hooks on both sides of the same baffle plate are centrally symmetrical about the center point of the baffle plate.

[0010] Furthermore, the connecting hook is J-shaped, and the long side of the J-shaped connecting hook is perpendicular to the two ends of the material blocking plate.

[0011] Furthermore, the abrasive plate is disc-shaped, and a connecting hole is provided at the bottom of the abrasive plate.

[0012] Furthermore, the connecting plate is annular and is provided with four first positioning holes, which are evenly distributed on the annular connecting plate. The baffle plate is provided with a second positioning hole, and bolts pass through the first positioning holes and the second positioning holes to fix the baffle plate to the connecting plate.

[0013] Furthermore, the connecting plate is located at the edge of the abrasive plate.

[0014] Compared with the prior art, the beneficial effects of this application are:

[0015] 1. The present application designs the abrasive plate as an integral type, and fixes the baffle plate and the abrasive plate through a connecting plate, thereby ensuring the baffle effect of the baffle plate and improving the overall strength of the abrasive plate to prevent damage to the abrasive plate.

[0016] 2. The present application divides the material baffle plate into four pieces, and the four material baffle plates are connected end to end through connecting hooks, and the connecting hooks are tightly connected to each other, thereby improving the supporting strength of the connection of the material baffle plates.

[0022] The present application is further described below in conjunction with the accompanying drawings and embodiments.

[0023] Example 1

[0024] A new type of retaining ring for a vertical mill, such as Figure 1-Figure 4As shown, it includes: an abrasive plate 1, a connecting plate 2 and a baffle plate 3, wherein the connecting plate 2 is perpendicular to the abrasive plate 1 and fixedly connected, and there are four baffle plates 3, which are connected end to end to form a ring-shaped baffle coil, and the baffle plate 3 is detachably connected to the connecting plate 2. In this way, the abrasive plate 1 is set as an integral structure, and the baffle plate 3 is set as a split structure, so that the abrasive plate 1 of the integral structure will not be damaged due to the pressure of the grinding head during the working process, and the connecting plate 2 is fixedly connected to the abrasive plate 1, so as to increase the strength of the connecting plate 2 and prevent the connecting plate 2 from detaching from the abrasive plate 1 after receiving an impact, and the four baffle plates 3 are connected end to end, so that although the baffle plate 3 is a split structure, it can still ensure a good support state and improve the support strength of the baffle ring.

[0025] like Figure 3 As shown, connecting hooks 6 are provided at both ends of the baffle plate 3 where they are connected end to end, and adjacent baffle plates 3 are connected by the connecting hooks 6. The connecting hooks 6 on both sides of the same baffle plate 3 are centrally symmetrical about the center point of the baffle plate 3. In this way, by connecting adjacent baffle plates 3 by the connecting hooks 6, the connection can be tighter, thereby improving the connection strength of the baffle plate 3.

[0026] like Figure 3 As shown, the connecting hook 6 is J-shaped, and the long side of the J-shaped connecting hook 6 is perpendicular to the two ends of the baffle plate 3, so that two adjacent J-shaped connecting hooks 6 can be tightly connected.

[0027] like Figure 1 As shown, the abrasive plate 1 is disc-shaped, and a connecting hole is provided at the bottom of the abrasive plate 1 to facilitate the connection with the rotating shaft of the vertical mill. The abrasive plate 1 contacts the grinding head during the rotation process to grind the raw materials on the abrasive plate 1.

[0028] like Figure 2 As shown, the connecting plate 2 is annular and is provided with four first positioning holes 5, which are evenly distributed on the annular connecting plate 2. The material baffle plate 3 is provided with second positioning holes 7, and the bolts 4 pass through the first positioning holes 5 and the second positioning holes 7 to fix the material baffle plate 3 on the connecting plate 2, thereby forming a complete material baffle ring.

[0029] like Figure 2 As shown, the connecting plate 2 is located at the edge of the abrasive plate 1, which can maximize the contact area between the abrasive plate 1 and the grinding head.

[0030] like Figure 4 As shown, the thickness of the connecting plate 2 is smaller than the thickness of the blocking plate 3 .

[0031] In the technical solution of the present application, the abrasive plate 1 is designed to be integral, so as to improve the overall strength of the abrasive plate 1 and prevent the abrasive plate 1 from breaking during the contact process with the grinding head, and the baffle plate 3 is detachably fixed to the abrasive plate 1 by using the connecting plate 2 fixedly connected to the abrasive plate 1. In this way, during the abrasive process of the abrasive plate 1 and the grinding head, the material can be blocked to prevent the raw material from leaking from the abrasive plate 1. The four baffle plates 3 are detachably connected to the connecting plate 2 by bolts 4. After one of the baffle plates 3 is damaged, the baffle plate 3 can be replaced alone. First, the bolts 4 are removed from the first positioning holes 5 and the second positioning holes 7, and the damaged baffle plate 3 is pulled out from the connecting hooks 6 of the adjacent baffle plates 3, and then the intact baffle plate 3 is inserted into the adjacent connecting hooks 6 from above, and finally the bolts 4 are inserted into the first positioning holes 5 and the second positioning holes 7, so as to complete the installation of the baffle plate 3.

[0032] Although the above describes the specific implementation methods of the present application in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present application. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present application, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present application.
