Description

Technical Field

[0001] The present application relates to the field of cement production equipment, and in particular to a V-shaped powder separator. Background Art

[0002] In cement production, the V-type powder classifier is a kind of disintegrating equipment specially used in conjunction with the roller press.

[0003] Roller presses are primarily used in cement production to process raw or clinker cement (limestone, gypsum, and other cement raw materials). The two rollers of a roller press exert high pressure on the material, squeezing it into a cake-like shape. The V-type powder separator's primary function is to break up the cake-like material after the roller press, thereby breaking it up and separating it into a powdery state.

[0004] In the existing technology, the V-type powder classifier includes a feed pipe and a V-type powder classifier body. The feed pipe is connected to the V-type powder classifier body. The multi-level breaking table, breaking plate, breaking grid and other components inside the V-type powder classifier body break the cake-like material into powdery material.

[0005] In the actual production process, the V-type powder classifier has a poor breaking effect, that is, the powdered material after being broken up by the V-type powder classifier still contains a lot of coarse powder, which affects the subsequent grinding efficiency of the material. Utility Model Content

[0006] In order to improve the effect of V-type powder separator on the dispersion of materials and reduce the content of coarse powder in the powdered materials after dispersion, the present application provides a V-type powder separator.

[0007] The present application provides a V-type powder separator, which adopts the following technical solution:

[0008] A V-shaped powder classifier includes a feed pipe, a V-shaped powder classifier body and a partition steel plate, the feed pipe is connected to the V-shaped powder classifier body, and the feed pipe transports cake-shaped materials into the interior of the V-shaped powder classifier body; the feed pipe includes a first feed pipe and a second feed pipe that are connected to each other, the first feed pipe is connected to the V-shaped powder classifier body, and the cross-sectional area of ​​the second feed pipe increases along the direction away from the V-shaped powder classifier body; the partition steel plate is vertically arranged, and the partition steel plate is fixed in the first feed pipe at the bottom.

[0009] By adopting the above technical solution and setting a partition steel plate in the middle of the first feed pipe, it is possible to reduce the cake-like material from sliding directly along the first feed pipe into the interior of the V-type powder classifier body, so that the cake-like material collides with the partition steel plate. The partition steel plate can break up the larger cake-like material into smaller cake-like material, thereby improving the breaking effect of the V-type powder classifier body on the cake-like material, reducing the content of coarse powder in the powdered material, and improving the subsequent grinding efficiency of the material.

[0010] Optionally, two partition steel plates are provided at intervals, and the two partition steel plates divide the first feed pipe into three channels.

[0011] By adopting the above technical solution, two partition steel plates are provided inside the first material reduction pipe, thereby increasing the probability of the cake-shaped material colliding with the first material feeding pipe.

[0012] Optionally, a scattering steel plate is further included, which is fixed on the side wall of the second feed pipe. A distance is set between the scattering steel plate and the separation steel plate, and the scattering steel plate is used to collide with the cake-shaped material.

[0013] By adopting the above technical solution, a scattering steel plate is set on the inner wall of the second feed pipe, so that two scattering structures are formed from top to bottom inside the feed pipe, thereby increasing the probability of collision between the cake-shaped material and the scattering steel plate and the separation steel plate.

[0014] Optionally, the angle between the broken-up steel plate and the horizontal plane is 11°.

[0015] By adopting the above technical solution, the scattering steel plate is set at 11° to the horizontal plane, ensuring that the material can be transported from the second feed pipe to the first feed pipe, while increasing the probability of collision between the cake-like material and the scattering steel plate, so as to further improve the scattering effect of the V-type powder classifier.

[0016] Optionally, a striking component is further included, which is fixed on the inner wall of the second feed pipe; the striking component includes a fixing part, a spring part and a striking part, the fixing part and the striking part are fixed at both ends of the spring part, the fixing part is fixedly connected to the inner wall of the second feed pipe, and the striking part is used to strike the cake-shaped material.

[0017] By adopting the above technical solution, when the cake-like material is fed into the feed pipe, it collides with the striking assembly, causing the spring member of the striking assembly to deform. As the spring member recovers its original shape, it drives the striking member to swing, causing it to strike the cake-like material, thereby breaking larger cakes into smaller ones, thereby improving the V-type powder classifier's disintegration effect.

[0018] Optionally, the striking assembly further includes a hose, which is sleeved on the outer circumference of the spring component, and two ends of the hose are respectively fixedly connected to the fixing component and the striking component.

[0019] By adopting the above technical solution and sleeved with a hose on the outer periphery of the spring part, the occurrence of material being stuck on the spring part is reduced, so that the spring part can be deformed freely.

[0020] Optionally, the striking member includes a connecting rod and a striking plate, one end of the connecting rod is fixedly connected to the spring member, and the other end of the connecting rod is fixedly connected to the striking plate.

[0021] By adopting the above technical solution, the connecting rod of the striking member can be easily fixedly connected to the spring member, and the striking plate has a larger striking area, so as to improve the striking effect of the striking member on the cake-shaped material.

[0022] Optionally, the striking plate is arranged at an acute angle to the vertical surface.

[0023] By adopting the above technical solution, the striking plate is arranged at an acute angle to the vertical plane, so that the striking plate can move in the horizontal direction, thereby increasing the striking range of the striking plate.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By installing a partition steel plate in the middle of the first feed pipe, it is possible to reduce the chance of cake-like materials sliding directly along the first feed pipe into the interior of the V-type powder concentrator body, causing the cake-like materials to collide with the partition steel plate. The partition steel plate can break up larger cake-like materials into smaller ones, thereby improving the V-type powder concentrator body's ability to break up cake-like materials, reducing the content of coarse powder in the powdery materials, and improving the subsequent grinding efficiency of the materials.

[0026] 2. By installing a breaking steel plate on the inner wall of the second feed pipe, a two-way breaking structure is formed from top to bottom inside the feed pipe, thereby increasing the probability of collision between the cake-like materials and the breaking steel plate and the separation steel plate. In other words, the feed pipe pre-breaks the larger cake-like materials into smaller ones, and then transports the smaller cake-like materials to the interior of the V-type powder classifier for further breaking, thereby reducing the operating burden of the V-type powder classifier and reducing the power loss of the V-type powder classifier. At the same time, it also improves the fineness of the powdered materials after being broken up by the V-type powder classifier and reduces the content of coarse powder.

[0027] 3. When the cake-like material is fed into the feed pipe, it collides with the striking assembly, causing the spring component of the striking assembly to deform. As the spring component recovers its original shape, it drives the striking component to swing, causing it to strike the cake-like material, thereby breaking larger cake-like materials into smaller ones, thereby improving the V-type powder classifier's disintegration effect.

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The embodiment of the present application discloses a V-type powder separator. Figure 1 The V-type powder classifier includes a feed pipe 1 and a V-type powder classifier body 2. The feed pipe 1 is connected to the V-type powder classifier body 2. The feed pipe 1 transports the cake-like material into the inside of the V-type powder classifier body 2; the multi-level breaking table, breaking plate, breaking grid and other components inside the V-type powder classifier body 2 break the cake-like material into powdery material.

[0035] Reference Figure 1 and Figure 2 The feed pipe 1 includes a first feed pipe 11 and a second feed pipe 12. The first feed pipe 11 is connected to the V-shaped powder classifier body 2. As it moves away from the V-shaped powder classifier body 2, the cross-sectional area of ​​the second feed pipe 12 increases.

[0036] Reference Figure 2 The V-type powder classifier also includes a partition steel plate 3 and a scattering steel plate 4, which are fixed inside the feed pipe 1 and are welded to the inner wall of the feed pipe 1.

[0037] Reference Figure 2 The partition steel plate 3 is vertically arranged and fixed in the first feed pipe 11 at the bottom. The partition steel plate 3 is welded to the inner wall of the first feed pipe 11. In this embodiment, two partition steel plates 3 are arranged at intervals, and the two partition steel plates 3 divide the first feed pipe 11 into three channels.

[0038] Reference Figure 2 One side of the scattering steel plate 4 is welded to the inner side wall of the second feed pipe 12, and a distance is set between the scattering steel plate 4 and the partition steel plate 3. The scattering steel plate 4 is used to collide the cake-shaped materials. In this embodiment, the angle between the scattering steel plate 4 and the horizontal plane is 11 degrees.

[0039] The implementation principle of a V-type powder separator in the embodiment of the present application is as follows:

[0040] Reference Figure 2 By setting a breaking steel plate 4 on the inner wall of the second feed pipe 12 and a partition steel plate 3 in the middle of the first feed pipe 11, two breaking structures are formed from top to bottom inside the feed pipe 1, thereby increasing the probability of collision between the cake-like material and the breaking steel plate 4 and the partition steel plate 3.

[0041] Reference Figure 2 The scattering steel plate 4 is set at an angle of 11° to the horizontal plane, which ensures that the material can be transported from the second feed pipe 12 to the first feed pipe 11, while increasing the probability of collision between the cake-like material and the scattering steel plate 4, so as to further improve the scattering effect of the V-type powder classifier.

[0042] Reference Figure 2 Two partition steel plates 3 are set inside the first material reduction pipe to ensure that the cake-like material can pass through the first feeding pipe 11 smoothly, while also increasing the probability of the cake-like material colliding with the first feeding pipe 11, so as to further improve the V-type powder classifier's effect of breaking up the cake-like material.

[0043] Reference Figure 2 , that is, the breaking steel plate 4 and the separating steel plate 3 inside the feed pipe 1 break up the larger cake-like materials into smaller cake-like materials in advance, and then transport the smaller cake-like materials to the inside of the V-type powder classifier body 2 for further breaking up; thereby reducing the operating burden of the V-type powder classifier body 2, reducing the power loss of the V-type powder classifier and subsequent material grinding; at the same time, it also improves the fineness of the powdered materials after being broken up by the V-type powder classifier and reduces the content of coarse powder. The numerical comparison of the indicators of the V-type powder classifier of the embodiment of the present application and the prior art is as follows:

[0044]

[0045] The lower the operating current of the V-type powder classifier, the lower the power consumption of the V-type powder classifier; the smaller the 0.08mm sieve residue value at the coarse powder outlet of the V-type powder classifier, the smaller the proportion of coarse powder in the powdered material after being dispersed by the V-type powder classifier, and the better the dispersion effect of the V-type powder classifier; the lower the power consumption of the material grinding process, the less electricity consumed by the grinding equipment, and the lower the electricity bill.

[0046] Example 2

[0047] The difference between this embodiment 2 and embodiment 1 is that:

[0048] Reference Figure 3 The V-type powder classifier further includes a striking assembly 5, which is fixed to the inner wall of the second feed pipe 12. In this embodiment, the striking assembly 5 is arranged between the scattering steel plate 4 and the partition steel plate 3, and a distance is set between the striking assembly 5 and the scattering steel plate 4 and the partition steel plate 3.

[0049] Reference Figure 3 and Figure 4 Specifically, the striking assembly 5 includes a fixing member 51, a spring member 52, a striking member 53, and a hose 54. The fixing member 51 and the striking member 53 are fixedly mounted at both ends of the spring member 52. The fixing member 51 is fixedly connected to the inner wall of the second feed pipe 12. The striking member 53 is used to strike the cake-shaped material. The hose 54 is sleeved around the outer periphery of the spring member 52, and the ends of the hose 54 are respectively fixedly connected to the fixing member 51 and the striking member 53. In this embodiment, the fixing member 51 is a hollow steel pipe that is welded to the inner wall of the second pipe via a connecting lug. In this embodiment, the striking member 53 includes a connecting rod 531 and a striking plate 532. One end of the connecting rod 531 is fixedly connected to the spring member 52, and the other end of the connecting rod 531 is fixedly connected to the striking plate 532. The striking plate 532 is arranged at an acute angle to the vertical plane. The ends of the hose 54 are respectively bonded to the fixing member 51 and the connecting rod 531.

[0050] The implementation principle of a V-type powder separator in the embodiment of the present application is as follows:

[0051] Reference Figure 3 and Figure 4 When the cake-like material is put into the feed pipe 1, the cake-like material will collide with the striking component 5 and cause the spring member 52 of the striking component 5 to deform. When the spring member 52 recovers its original shape, the spring member 52 will drive the striking member 53 to swing, causing the striking member 53 to hit the cake-like material, thereby beating the larger cake-like material into smaller cake-like material, thereby improving the breaking effect of the V-type powder classifier. A hose 54 is sleeved on the outer periphery of the spring member 52 to reduce the occurrence of material being stuck on the spring member 52, allowing the spring member 52 to deform freely. In this embodiment, a plurality of through holes 5321 are opened on the striking plate 532 to further improve the striking effect of the striking plate 532 on the cake-like material.

[0052] Reference Figure 3 and Figure 4 The striking plate 532 is set at an acute angle to the vertical plane, so that when the cake-shaped material collides with the striking plate 532, the striking plate 532 can move in the horizontal direction, thereby increasing the striking range of the striking plate 532.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
