Description

Technical Field

[0001] The utility model belongs to the technical field of feeding devices, and specifically relates to an anti-blocking feeding structure for a vertical mill. Background Art

[0002] A vertical mill can efficiently process and grind materials. The materials are orderly added into the vertical mill through a feeding channel and are rolled under the action of a rolling roller and a disc.

[0003] When most existing vertical mills feed materials, the materials are directly put into a hopper and then conveyed into the vertical mill. However, the volume of some materials is too large, and the materials cannot be stirred and crushed before feeding, resulting in a large amount of large-volume materials accumulating at the feeding port of the hopper, thus causing a blockage phenomenon and affecting the grinding efficiency of subsequent materials.

[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0005] To solve the above technical problems that when most existing vertical mills feed materials, the materials are directly put into a hopper and then conveyed into the vertical mill. However, the volume of some materials is too large, and the materials cannot be stirred and crushed before feeding, resulting in a large amount of large-volume materials accumulating at the feeding port of the hopper, thus causing a blockage phenomenon and affecting the grinding efficiency of subsequent materials, the basic concept of the technical solution adopted by the present utility model is as follows:

[0006] An anti-blocking feeding structure for a vertical mill, comprising a vertical mill;

[0007] A base fixedly connected to the bottom end of the vertical mill, an anti-blocking mechanism is arranged on the vertical mill, and an auxiliary anti-blocking mechanism is arranged on one side of the anti-blocking mechanism. The anti-blocking mechanism includes a support plate fixedly connected to the top end of the vertical mill:

[0008] A motor is fixedly connected to the bottom end of the support plate, a sliding sleeve is fixedly connected to the output end of the motor, a first spring is fixedly connected to the top end inner wall of the sliding sleeve, a rotating column is fixedly connected to the end of the first spring away from the inner wall of the sliding sleeve, the outer wall of the rotating column is slidably connected to the inner wall of the sliding sleeve, a stirring rod is fixedly connected to the outer wall of the rotating column, a conveying cylinder is communicated with the outer wall of the vertical mill, a feeding pipe is communicated with the outer wall of the conveying cylinder, a feeding hopper is communicated with the end of the feeding pipe away from the conveying cylinder, a force-applying plate is fixedly connected to the top end of the feeding hopper, a force-receiving plate is in contact with the top end of the force-applying plate, and a connecting rod is fixedly connected to the outer wall of the force-receiving plate at the top end, and the end of the connecting rod away from the force-receiving plate is fixedly connected to the outer wall of the rotating column.

[0009] As a preferred embodiment of the present utility model, the auxiliary anti-blocking mechanism includes a fixing plate fixedly connected to the top end of the conveying cylinder. A sliding hole is formed in the outer wall of the fixing plate, and a sliding rod is slidably connected to the inner wall of the sliding hole. One end of the sliding rod is fixedly connected with a knocking block, and the other end of the sliding rod away from the knocking block is fixedly connected with an inclined plate. One end of the inclined plate close to the sliding rod is fixedly connected with a second spring, and the other end of the second spring away from the inclined plate is fixedly connected to the outer wall of the fixing plate.

[0010] As a preferred embodiment of the present utility model, the bottom end of the force-bearing plate and the top end of the force-applying plate are both provided with inclined surfaces, and the outer walls of the inclined surfaces provided by both are in fitting contact with each other.

[0011] As a preferred embodiment of the present utility model, the number of the stirring rods is several, and the stirring rods are evenly distributed in three groups on the outer wall of the rotating column.

[0012] As a preferred embodiment of the present utility model, the inner wall of the sliding sleeve is in fitting contact with the outer wall of the rotating column, and the rotating column extends into the feeding pipe.

[0013] As a preferred embodiment of the present utility model, the initial state of the knocking block is to be in contact with the outer wall of the feeding pipe.

[0014] As a preferred embodiment of the present utility model, the position of the rotating push rod is less than the distance between the initial state of the inclined plate and the feeding pipe.

[0015] The present utility model has the following beneficial effects compared with the prior art:

[0016] For the present utility model, start the motor, and then put the material into the hopper. The output end of the motor will drive the rotating column to rotate. When the rotating column rotates, it will drive the stirring rod to rotate. The material is stirred and flowed and struck by the stirring rod, so that the larger pieces of material are dispersed, preventing the large pieces of material from blocking between the hopper and the feeding pipe. At the same time, when the rotating column rotates, it will drive the connecting rod to rotate. When the connecting rod rotates, it can drive the force-bearing plate to rotate. When the force-bearing plate rotates, it will contact and be extruded by the force-applying plate. The force-bearing plate being extruded will drive the connecting rod to move upward. When the connecting rod moves upward, it can drive the rotating column to move upward on the inner wall of the sliding sleeve. At the same time, the first spring will be compressed during the moving process. When the force-bearing plate continues to rotate and no longer contacts the force-applying plate, the first spring can rebound to drive the rotating column to move downward. In this way, the rotating column can be driven to form a reciprocating up and down movement, thereby impacting the part where the hopper is connected to the feeding pipe up and down to prevent the material from blocking therein. Then the material falls into the conveying cylinder and is finally conveyed to the vertical mill.

[0017] In the present utility model, when the connecting rod rotates, it can also drive the rotating push rod to rotate. When the rotating push rod rotates, it will perform a squeezing operation on the inclined plate. The squeezed inclined plate will drive the sliding rod to move to the right, and at the same time drive the knocking block away from the outer wall of the feeding pipe, and then drive the second spring to stretch. As the rotating push rod rotates and no longer contacts the inclined plate, the second spring rebounds and resets to drive the sliding rod to quickly move to the left, thereby driving the knocking block to knock on the outer wall of the feeding pipe, so as to vibrate the feeding pipe, and thus the small amount of materials adhering to the inner wall of the feeding pipe can be knocked off, preventing the subsequent accumulation and causing blockage of the feeding pipe.

Specific Embodiments

[0025] To make the purposes, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0026] As Figures 1 to 4As shown in the figure, an anti-blocking feeding structure for a vertical mill includes a vertical mill 1, a base 2 fixedly connected to the bottom end of the vertical mill 1, an anti-blocking mechanism 31 provided on the vertical mill 1, and an auxiliary anti-blocking mechanism 32 provided on one side of the anti-blocking mechanism 31. The anti-blocking mechanism 31 includes a support plate 311 fixedly connected to the top end of the vertical mill 1. A motor 312 is fixedly connected to the bottom end of the support plate 311. The output end of the motor 312 is fixedly connected to a sliding sleeve 313. A first spring 314 is fixedly connected to the top end inner wall of the sliding sleeve 313. One end of the first spring 314 away from the inner wall of the sliding sleeve 313 is fixedly connected to a rotating column 315. The outer wall of the rotating column 315 is slidably connected to the inner wall of the sliding sleeve 313. Stirring rods 316 are fixedly connected to the outer wall of the rotating column 315. A conveying cylinder 3112 is communicated with the outer wall of the vertical mill 1. A feeding pipe 3111 is communicated with the outer wall of the conveying cylinder 3112. One end of the feeding pipe 3111 away from the conveying cylinder 3112 is communicated with a feeding hopper 3110. A force-applying plate 319 is fixedly connected to the top end of the feeding hopper 3110. A force-receiving plate 318 is in contact with the top end of the force-applying plate 319. A connecting rod 317 is fixedly connected to the outer wall of the top end of the force-receiving plate 318. One end of the connecting rod 317 away from the force-receiving plate 318 is fixedly connected to the outer wall of the rotating column 315.

[0027] Further, the number of the stirring rods 316 is several, and the stirring rods 316 are evenly distributed in three groups on the outer wall of the rotating column 315. In this way, the materials put into it can be stirred and flowed at high speed by continuous hitting, so that the large pieces of materials can be hit into small pieces of materials to prevent the materials from blocking the feeding pipe 3111.

[0028] Furthermore, the inner wall of the sliding sleeve 313 is fitted and matched with the outer wall of the rotating column 315, and the rotating column 315 extends into the feeding pipe 3111. In this way, the stability of the rotating column 315 during rotation can be ensured. At the same time, when the rotating column 315 extends into the feeding pipe 3111, the communication port between the feeding hopper 3110 and the feeding pipe 3111 can be dredged during the up-and-down reciprocating movement.

[0029] The auxiliary anti-blocking mechanism 32 includes a fixing plate 321 fixedly connected to the top end of the conveying cylinder 3112. A sliding hole is opened on the outer wall of the fixing plate 321. A sliding rod 322 is slidably connected to the inner wall of the sliding hole. One end of the sliding rod 322 is fixedly connected to a knocking block 323. An inclined plate 324 is fixedly connected to the other end of the sliding rod 322 away from the knocking block 323. A second spring 325 is fixedly connected to the end of the inclined plate 324 close to the sliding rod 322. One end of the second spring 325 away from the inclined plate 324 is fixedly connected to the outer wall of the fixing plate 321.

[0030] Further, the initial state of the knocking block 323 is attached to the outer wall of the feeding pipe 3111. In this way, when the second spring 325 rebounds, its resilience can push the knocking block 323 to vibrate the outer wall of the feeding pipe 3111, thereby further improving the anti-blocking effect.

[0031] Furthermore, the position of the rotating push rod 326 is less than the distance between the initial state of the inclined plate 324 and the feeding pipe 3111. In this way, during the rotation of the rotating push rod 326, it can contact and squeeze the inclined groove on the outer wall of the inclined plate 324, thereby pushing the sliding rod 322 and the knocking block 323 to move, so as to vibrate the feeding pipe 3111.

[0032] The implementation principle of the anti-blocking feeding structure of a vertical mill in this embodiment is as follows: First, start the motor 312, and then put the material into the hopper 3110. The output end of the motor 312 will drive the rotating column 315 to rotate. When the rotating column 315 rotates, it will drive the stirring rod 316 to rotate. The stirring rod 316 stirs and flows the material while hitting it, so that the larger pieces of material are dispersed, preventing the large pieces of material from blocking between the hopper 3110 and the feeding pipe 3111. At the same time, during the rotation of the rotating column 315, it will drive the connecting rod 317 to rotate. When the connecting rod 317 rotates, it can drive the force-receiving plate 318 to rotate. When the force-receiving plate 318 rotates, it will contact and be squeezed by the force-applying plate 319. The force-receiving plate 318 that is squeezed will drive the connecting rod 317 to move upward. When the connecting rod 317 moves upward, it can drive the rotating column 315 to move upward inside the sliding sleeve 313. At the same time, during the movement, it will squeeze and compress the first spring 314. When the force-receiving plate 318 continues to rotate and no longer contacts the force-applying plate 319, the first spring 314 can rebound to drive the rotating column 315 to move downward. In this way, the rotating column 315 can be driven to form an up-and-down reciprocating motion, thereby impacting the part where the hopper 3110 is connected to the feeding pipe 3111 up and down to prevent the material from blocking therein. Then the material falls into the conveying cylinder 3112 and is finally conveyed to the vertical mill 1.

[0033] When the connecting rod 317 rotates, it can also drive the rotating push rod 326 to rotate. When the rotating push rod 326 rotates, it will perform a squeezing operation on the inclined plate 324. The inclined plate 324 subjected to the squeezing will drive the sliding rod 322 to move to the right, and at the same time drive the knocking block 323 away from the outer wall of the feed pipe 3111, and then drive the second spring 325 to stretch. As the rotating push rod 326 rotates and no longer contacts the inclined plate 324, the second spring 325 rebounds and resets to drive the sliding rod 322 to quickly move to the left, thereby driving the knocking block 323 to knock on the outer wall of the feed pipe 3111, so as to vibrate the feed pipe 3111, and thus the small amount of material adhering to the inner wall of the feed pipe 3111 can be knocked off, preventing the subsequent accumulation of a small amount into a large amount and causing the blockage of the feed pipe 3111.
