Description

Technical Field

[0001] The utility model relates to the technical field of activation ring devices, in particular to an internal material activation ring device for cement grinding. Background Art

[0002] In the cement grinding process, a vertical grinding mill (abbreviated as vertical mill) is used; vertical mills are increasingly used in cement plant production lines and new modern cement production lines. More than 90% of coal and raw material grinders use vertical mills; this is mainly because vertical mills have a series of significant advantages, which make them occupy an important position in cement grinding; vertical mills have been widely used and recognized in the field of cement grinding for their advantages such as high efficiency, energy saving, environmental protection, and easy maintenance.

[0003] An activation ring is an annular device installed inside grinding equipment (such as ball mills, vertical mills, etc.) to optimize the grinding process and improve grinding efficiency. Its main functions include separating the grinding bodies, preventing back-grading of the grinding bodies, controlling the material flow rate, and improving the grinding efficiency and mill output. By adjusting the distribution of the grinding bodies and the flow state of the material, the activation ring can ensure the continuity and stability of the grinding process, thereby improving product quality and output.

[0004] Since the activation ring is used to separate the grinding media (such as steel balls, steel segments, etc.) in the grinding body to prevent them from being over-concentrated or reversely classified, and to ensure the uniform distribution of the grinding media, the components of the activation ring are very easy to wear in actual use. Traditional activation rings are usually cast in one piece and have a complex structure. Therefore, it is time-consuming and laborious to replace the worn parts of the activation ring. Usually, some parts of the activation ring are not worn, but when replacing the worn parts, the unworn parts need to be removed as well, which increases the workload of the staff when replacing the worn parts of the activation ring. Utility Model Content

[0005] The main purpose of the utility model is to provide an inner material activation ring device for cement grinding, which can effectively solve the problems of complicated operation, time-consuming and labor-intensive operation when workers replace the worn parts of the activation ring.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] An internal material activation ring device for cement grinding includes a fixed disc, a material blocking assembly is provided on the outside of the fixed disc, a blocking assembly is provided in the middle of the upper end of the fixed disc, a lining assembly is provided on the upper side of the fixed disc, and a fixed assembly is provided on the upper side of the lining assembly.

[0008] Preferably, the material baffle assembly includes several arc-shaped material baffle plates, several through circular grooves 2 are opened on the lower side of the outer surface of several of the arc-shaped material baffle plates, several inner surfaces of several of the circular grooves 2 are threadedly connected with bolts 1, and several circular grooves 1 are opened in the middle of the outer surface of the fixed disc, and several of the bolts 1 are threadedly connected to the inner surfaces of several of the circular grooves 1.

[0009] Preferably, the blocking assembly includes a cylinder, which is fixedly connected to the middle part of the upper end of the fixed disc, and a conical block is fixedly connected to the upper end of the cylinder. A plurality of through-holes are opened in the middle part of the upper end of the fixed disc.

[0010] Preferably, the lining plate assembly includes a plurality of lining plates, each of which is provided with a placement groove on the upper end, and each of which is provided with a through circular hole 2 on the lower side of the inner surface of the placement groove.

[0011] Preferably, the fixing assembly includes a number of fixing blocks that is the same as the number of the placement slots, each of the fixing blocks is provided with a through circular hole three on the upper end, the inner surface of each circular hole three is threadedly connected with a bolt two, and several of the bolts two are threadedly connected to the inner surfaces of several of the circular holes two and several of the circular holes one.

[0012] Preferably, the upper end of each lining plate is concave from the outside to the inside, and the plurality of circular grooves 1, the plurality of circular grooves 2, the plurality of circular holes 1, the plurality of circular holes 2 and the plurality of circular holes 3 are distributed in an arc-shaped array.

[0013] Preferably, the number of the circular grooves 1 and the number of the circular grooves 2 are the same, and the number of the circular holes 1, the number of the circular holes 2 and the number of the circular holes 3 are the same.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The utility model can fix several lining plates on the fixed disc respectively through the setting of the fixing assembly, and the lining plates are several rather than a whole, so that the staff can replace only the worn lining plates according to the actual situation, and the unworn lining plates do not need to be replaced. Since each lining plate can be installed and removed independently, it is not necessary to remove the unworn lining plates when installing and replacing the worn lining plates. When the staff replaces the activation ring, they can prescribe the right medicine and only replace the worn parts, which reduces the workload and improves the work efficiency.

[0016] 2. The conical block provided in the present invention can ensure that when the device is installed in a cement grinding mill, cement powder will not accumulate in the middle of the device when the mill is grinding cement, but will slide onto several lining plates. At the same time, since each lining plate is concave from the outside to the inside, during the cement grinding process, cement will also gather in the middle of several lining plates instead of accumulating on the edges of the lining plates, so that excessive cement accumulation will affect the normal operation of the device and the cement cannot be fully ground.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 and Figure 2 As shown, an internal material activation ring device for cement grinding includes a fixed disc 2, a material blocking component 1 is provided on the outside of the fixed disc 2, a blocking component 3 is provided in the middle of the upper end of the fixed disc 2, a lining component 4 is provided on the upper side of the fixed disc 2, and a fixed component 5 is provided on the upper side of the lining component 4.

[0026] In a specific implementation, the liner assembly 4 is fixedly mounted on the fixed disc 2 through the fixing assembly 5, the material blocking assembly 1 is fixedly mounted on the outer surface of the fixed disc 2, and then the device is fixedly mounted in a cement grinding machine. After long-term use of the device in the cement grinding machine, it is necessary to regularly check and replace worn parts.

[0027] If the fixing component 5 needs to be replaced, you only need to directly dismantle the worn fixing component 5 according to the actual situation; if the worn lining component 4 needs to be replaced, you only need to first dismantle the fixing component 5 and the blocking component 1 that fix the worn lining component 4, and then remove the worn lining component 4 for replacement; if the worn blocking component 1 needs to be replaced, you only need to directly remove the worn blocking component 1 from the fixed disc 2.

[0028] Specifically, in order to enable the staff to prescribe the right medicine when replacing the wear parts of the activation ring device, thereby reducing the workload of the staff when replacing the wear parts, refer to Figure 3 and Figure 4 The material blocking assembly 1 includes a plurality of arc-shaped material blocking plates 12, and a plurality of through circular grooves 13 are opened on the lower side of the outer surface of the plurality of arc-shaped material blocking plates 12, and the inner surfaces of the plurality of circular grooves 13 are threadedly connected with bolts 14. The middle part of the outer surface of the fixed disc 2 is provided with a plurality of circular grooves 11, and the plurality of bolts 14 are threadedly connected with the inner surfaces of the plurality of circular grooves 11;

[0029] Further reading Figure 3 The blocking assembly 3 includes a cylinder 32, which is fixedly connected to the middle of the upper end of the fixed disc 2. A conical block 33 is fixedly connected to the upper end of the cylinder 32. The middle of the upper end of the fixed disc 2 is provided with a plurality of through holes 31;

[0030] Further reading Figure 5 and Figure 6 The lining assembly 4 includes a plurality of linings 41, each of which has a placement groove 42 at the upper end, and a through-hole 43 is formed on the lower side of the inner surface of each placement groove 42;

[0031] Further reading Figure 5 The fixing assembly 5 includes a fixing block 51 having the same number as the placement slots 42. A through circular hole 3 52 is formed on the upper end of each fixing block 51. A bolt 2 53 is threadedly connected to the inner surface of each circular hole 3 52. Several bolts 2 53 are threadedly connected to the inner surfaces of several circular holes 2 43 and several circular holes 1 31.

[0032] Further reading Figure 3 、 Figure 4 、 Figure 5 and Figure 6The upper end of each lining plate 41 is concave from the outside to the inside, and the circular grooves 11, the circular grooves 13, the circular holes 31, the circular holes 43 and the circular holes 52 are distributed in an arc array; the number of the circular grooves 11 and the circular grooves 2 13 is the same, and the number of the circular holes 31, the circular holes 2 43 and the circular holes 3 52 is the same.

[0033] The number of the plurality of lining plates 41 mentioned above is an integer multiple of the number of the plurality of arc-shaped material blocking plates 12;

[0034] In a specific implementation, if it is necessary to fix the plurality of lining plates 41 on the fixed disc 2, it is only necessary to place the plurality of lining plates 41 on the fixed disc 2, so that the plurality of second circular holes 43 and the plurality of first circular holes 31 are in a one-to-one corresponding position. Since the number of the plurality of fixing blocks 51 and the plurality of placement slots 42 is the same, the plurality of fixing blocks 51 are placed in the plurality of placement slots 42 in a one-to-one corresponding manner. At this time, the plurality of first circular holes 31, the plurality of second circular holes 43 and the plurality of third circular holes 52 are all in a one-to-one corresponding position. Then, the plurality of second bolts 53 are first inserted into the third circular holes 52, and the plurality of fixing blocks 51 and the plurality of lining plates 41 are fixed to the fixed disc 2 by the plurality of second bolts 53.

[0035] Then, the plurality of circular grooves 11 and the plurality of circular grooves 2 13 are matched one by one, and the plurality of arc-shaped baffle plates 12 are fixedly mounted on the outer surface of the fixed disc 2 by the plurality of bolts 14. Since the number of the plurality of lining plates 41 is an integer multiple of the number of the plurality of arc-shaped baffle plates 12, the two side edges of each arc-shaped baffle plate 12 are in a straight line with the edge of the lining plate 41.

[0036] After the device is installed in a grinding machine for grinding cement for a long time, the lining plate 41 is usually easy to wear. If the worn lining plate 41 needs to be replaced, since the lining plates 41 are several, not a whole, and each lining plate 41 is fixed to the fixed disc 2 by a corresponding fixing block 51 and a bolt 2 53, and the arc-shaped baffle plate 12 is not a whole, but several, so when the worn lining plate 41 needs to be replaced, first, it is only necessary to disassemble the arc-shaped baffle plate 12 fixed on the outer surface of the fixed disc 2 corresponding to the installation position of the worn lining plate 41. shaped baffle plate 12 is sufficient. Since both side edges of each arc-shaped baffle plate 12 are in a straight line with the edge of the lining plate 41, after removing the arc-shaped baffle plate 12 at the corresponding position, it will not hinder the subsequent removal and removal of the worn lining plate 41. The remaining arc-shaped baffle plates 12 corresponding to the installation positions of the unworn lining plates 41 do not need to be removed. Then, the corresponding fixing blocks 51 for fixing the worn lining plates 41 are removed, and the worn lining plates 41 can be removed. The new lining plates 41 can be installed according to the above operations.

[0037] Since the arc-shaped baffle plate 12 is divided into several parts, the lining plate 41 is also divided into several parts, and they are not a whole. At the same time, each lining plate 41 is fixed to the fixed disc 2 by an independent fixing block 51. Therefore, in the operation of disassembling, replacing, and installing the worn lining plate 41, it is only necessary to prescribe the right medicine for the case and disassemble the worn lining plate 41. The unworn lining plate 41 does not need to be disassembled. At the same time, the unworn lining plate 41 will not affect the operation process of replacing the worn lining plate 41. This provides convenience for the staff to replace the worn parts of the device and improves work efficiency.

[0038] Since each lining plate 41 is in a concave state from the outside to the inside, when the device is installed in a grinder for grinding cement, during the process of grinding cement in the grinder, the cement powder will always slide to the middle position of the several lining plates 41, and will not accumulate on the edge of the lining plates 41. In this way, during cement grinding, the normal operation of the device will not be affected by the accumulation of cement on the edge of the lining plate 41. At the same time, the cement always gathers in the middle of the lining plate 41, which is also conducive to the full grinding and crushing of the cement. At the same time, the several fixing blocks 51 are all rounded, and their cooperation with the conical block 33 prevents the cement from accumulating in the center of the device, and the cement will also slide on the several lining plates 41.

[0039] The working principle of this utility model is:

[0040] Place the lining plates 41 on the fixed disc 2, and place the fixing blocks 51 corresponding to the number of placement slots 42 on the placement slots 42, then use the second bolts 53 to fix the fixing blocks 51 and the lining plates 41 on the fixed disc 2, and use the first bolts 14 to fix the arc-shaped baffle plates 12 on the fixed disc 2;

[0041] If the worn liner 41 needs to be replaced, first remove the arc-shaped material baffle plate 12 corresponding to the installation position of the worn liner 41, and then remove the fixing block 51 used to fix the worn liner 41. The worn liner 41 can be removed from the fixed disc 2 for subsequent replacement work.

[0042] 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 illustrative of the principles of 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.
