Description

Technical Field

[0001] This utility model relates to the field of tower mill technology, and in particular to a tower mill with a function of reducing cyclic load. Background Technology

[0002] Tower mills are mainly composed of a transmission system, tower body, spiral agitator, and protective lining. As a highly efficient crushing equipment, tower mills have the following comprehensive advantages: by providing strong extrusion, grinding, and internal classification to the ore, tower mills greatly reduce system power. Tower mills can easily achieve internal classification in the crushing process, and over-crushing is greatly reduced.

[0003] However, the feed hoppers of tower mills are mostly designed with a fixed diameter, which cannot adapt the feeding speed according to the grinding state inside the machine. When the feeding is too fast, the material inside the machine accumulates, and the grinding media cannot fully contact and crush all the material, resulting in a large number of unground coarse particles being retained, requiring repeated grinding. When the feeding is too slow, the equipment is prone to idling, and the ineffective collisions between the grinding media increase, which not only wastes energy but also aggravates the wear of the media. Therefore, how to solve this problem is something we need to consider. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tower mill with a function of reducing cyclic load. It is equipped with a guide plate, a bidirectional threaded rod, and a slider, which can adjust the feed hopper discharge diameter, thereby adjusting the feed speed, reducing ineffective circulation, and lowering the equipment's cyclic load.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tower mill with a function of reducing circulating load includes a support plate, a rotating groove inside the support plate, an organic body rotatably connected to the bottom of the rotating groove, a second motor mounted on the upper end of the organic body, the output shaft of the second motor extending into the interior of the organic body and fixedly connected to a rotating shaft, spiral blades fixedly connected to the outer wall of the rotating shaft, a cyclone tube fixedly connected to the upper end of the organic body, an overflow pipe fixedly connected to one side wall of the organic body, the overflow pipe communicating with the cyclone tube through a connecting pipe, a water supply pipe fixedly connected to the other side wall of the organic body, a feed hopper fixedly connected to the upper end of the organic body, guide plates penetrating both sides of the feed hopper, a discharge trough on one side wall of the organic body, a movable groove on the top inner side of the discharge trough, a baffle plate at the discharge trough, the baffle plate cooperating with the discharge trough and the movable groove, and a moving mechanism for moving the two guide plates at the upper end of the organic body.

[0007] Preferably, a gear ring is fixedly connected to the outer wall of the machine body, a first motor is installed at the upper end of the support plate, the output shaft of the first motor extends into the rotating groove and is fixedly connected to a gear, the gear meshing with the gear ring.

[0008] Preferably, the moving mechanism includes a fixed plate fixedly connected to the upper end of the machine body, a sliding groove is provided in the fixed plate, and a bidirectional threaded rod is rotatably connected between the inner walls of the two sides of the sliding groove, and a slider is threaded to both threaded ends of the bidirectional threaded rod.

[0009] Preferably, one end of each of the two sliders is slidably connected to the inner wall of the chute, and the other end of each of the two sliders is fixedly connected to a connecting plate. The other side of each of the two connecting plates extends to the outside and is fixedly connected to the side wall of the corresponding guide plate.

[0010] Preferably, a third motor is installed on the outer wall of the fixing plate, and the output shaft of the third motor extends into the groove and is fixedly connected to one end of the bidirectional threaded rod.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. The structure includes a guide plate, a bidirectional threaded rod, and a slider. The bidirectional threaded rod drives the slider and connecting plate to move, thereby adjusting the distance between the two guide plates. This changes the effective discharge diameter of the feed hopper, allowing for the regulation of the material feeding speed. This reduces ineffective circulation from the feeding end and helps to reduce the overall circulating load of the equipment.

[0014] 2. The structure includes a gear ring, a first motor, and gears. The first motor drives the gears to rotate, and the meshing of the gears and gear rings drives the machine body to rotate stably. The centrifugal force generated by the rotation of the machine body allows the material to come into fuller contact with the grinding media, reducing grinding dead angles, improving grinding uniformity, and thus reducing the circulating load caused by insufficient grinding of materials.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-6 A tower mill with a function of reducing circulating load includes a support plate 1, a rotating groove 2 is opened in the support plate 1, and a body 3 is rotatably connected to the inner bottom of the rotating groove 2. The body 3 is rotatably connected to the inner bottom of the rotating groove 2 through a bearing. A gear ring 4 is fixedly connected to the outer wall of the body 3. A first motor 5 is installed at the upper end of the support plate 1. The first motor 5 is a servo motor. The end of the output shaft of the first motor 5 extends into the interior of the rotating groove 2 and is fixedly connected to a gear 6. The gear 6 meshes with the gear ring 4. The first motor 5 drives the gear 6 to rotate, which in turn causes the gear ring 4 to drive the body 3 to rotate. When the body 3 rotates, the internal material will generate circumferential motion and centrifugal force, which can not only avoid material accumulation, but also allow the material to contact the grinding media (such as steel balls) more fully, improve grinding efficiency, reduce the proportion of unground material, and reduce the number of cycles.

[0024] The upper end of the machine body 3 is equipped with a second motor 7, which is a servo motor. The output shaft of the second motor 7 extends into the interior of the machine body 3 and is fixedly connected to a rotating shaft 8. The outer wall of the rotating shaft 8 is fixedly connected to a spiral blade 9. The rotating shaft 8 and the spiral blade 9 are driven to rotate by the second motor 7, which further improves the fineness of a single grinding, reduces the amount of coarse particles that need to be ground in cycles, and reduces the cycle load. The upper end of the machine body 3 is fixedly connected to a cyclone pipe 10, and one side wall of the machine body 3 is fixedly connected to an overflow pipe 11. The overflow pipe 11 is connected to the cyclone pipe 10 through a connecting pipe 12. Valves are provided on both the cyclone pipe 10 and the overflow pipe 11. The flow rate and grading accuracy can be adjusted by using the valves on both. The other side wall of the machine body 3 is fixedly connected to a water supply pipe 13. The independent water supply pipe 13 can replenish water according to the moisture content of the material, reduce the decrease in grinding efficiency caused by fluctuations in the material state, and indirectly reduce the cycle load.

[0025] The upper end of the machine body 3 is fixedly connected to a feeding hopper 14. Both sides of the feeding hopper 14 are provided with guide plates 15. Both guide plates 15 are composed of rectangular plates and inclined plates. The upper end of the machine body 3 is provided with a moving mechanism for moving the two guide plates 15. The moving mechanism includes a fixed plate 16 fixedly connected to the upper end of the machine body 3. A slide groove 17 is opened in the fixed plate 16. A bidirectional threaded rod 18 is rotatably connected between the two inner walls of the slide groove 17. Both threaded ends of the bidirectional threaded rod 18 are threadedly connected to sliders 19. One end of each slider 19 is slidably connected to the inner wall of the slide groove 17. The other end of each slider 19 is fixedly connected to a connecting plate 20. The other side of each connecting plate 20 extends to the outside and is fixedly connected to the side wall of the corresponding guide plate 15. A third motor 21 is installed on the outer wall of the fixed plate 16. The third motor 21 is a servo motor. The end of the output shaft of the third motor 21 extends into the slide groove 17 and is fixedly connected to one end of the bidirectional threaded rod 18.

[0026] When the third motor 21 drives the bidirectional threaded rod 18 to rotate, the slider 19 will cause the two guide plates 15 to move closer or further away synchronously, thereby changing the effective discharge diameter of the feed hopper 14. When the guide plates 15 move closer, the discharge channel will be narrowed, slowing down the feeding speed; when they move further away, the channel will be widened, increasing the feeding amount. This allows the feeding amount to be adjusted according to the grinding state inside the machine body 3, avoiding overloading and increasing the amount of unground material, thus reducing the circulating load. A discharge trough 22 is provided on one side wall of the machine body 3, and a moving groove 23 is provided at the top inner part of the discharge trough 22. A baffle 24 is provided, which cooperates with the discharge chute 22 and the moving chute 23. A rubber sealing strip is provided on the contact surface of the baffle 24 with the discharge chute 22 and the moving chute 23 to ensure that there is no leakage of material during the grinding process. The baffle 24 can slide up and down in the moving chute 23 to realize the opening and closing of the discharge chute 22 and control the discharge of material. An installation plate 25 is fixedly connected to one side wall of the machine body 3. An electric telescopic rod 26 is installed at the lower end of the installation plate 25. A lifting block 27 is fixedly connected to the telescopic end of the electric telescopic rod 26. The lifting block 27 is fixedly connected to the baffle 24.

[0027] In this utility model, when the tower mill is working, the material to be ground is first fed into the feed hopper 14. At this time, the third motor 21 is started, driving the bidirectional threaded rod 18 to rotate in the slide groove 17, which drives the sliders 19 on both sides and the connecting plate 20 to move, thereby adjusting the distance between the two guide plates 15 and controlling the effective discharge diameter of the feed hopper 14, so that the material enters the machine body 3 at a speed that matches the grinding capacity of the machine body 3, avoiding material accumulation caused by feeding too fast or equipment idling caused by feeding too slow, improving grinding efficiency and reducing ineffective cycles;

[0028] After the material enters the machine body 3, the second motor 7 is started, driving the rotating shaft 8 and the spiral blades 9 to rotate at high speed. The spiral blades 9 generate shearing and extrusion forces on the material, assisting the grinding media in crushing and grinding the material. On the other hand, they convey the material at the bottom of the machine body 3 upwards, forming vertical convection and preventing material stratification. At the same time, the first motor 5 is started, driving the gear 6 to rotate. The rotation of the gear 6 will drive the meshing gear ring 4 to rotate, which in turn drives the machine body 3 to rotate. Centrifugal force is used to make the material and the grinding media more fully contacted, further improving the grinding uniformity and efficiency.

[0029] When it is necessary to discharge the coarse material remaining in the machine body 3 or to complete the batch grinding, the electric telescopic rod 26 is activated to extend and retract, which drives the lifting block 27 and the baffle 24 to slide up and down in the moving groove 23, opening the discharge groove 22, thereby discharging the coarse material or residual material.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
