Description
Technical Field
[0001] This utility model relates to the field of cone mill technology, specifically to a cone mill discharge particle size limiting and adjusting device. Background Technology
[0002] A cone crusher is a type of crushing machinery suitable for raw materials in the metallurgical, construction, road building, chemical, and silicate industries. Depending on the crushing principle and product particle size, it is available in many models. Cone crushers are widely used in mining, metallurgy, building materials, highways, railways, water conservancy, and chemical industries. They feature a large crushing ratio, high efficiency, low energy consumption, and uniform product particle size, making them suitable for medium and fine crushing of various ores and rocks.
[0003] If the feed material in a cone crusher is too large, it may lead to incomplete crushing and uneven particle size of the discharged material, resulting in the crushed material not meeting the standards. However, in the existing technology, there is no corresponding discharge limiting measure after the cone crusher finishes discharging. All the crushed material is discharged together, which not only affects the processing quality of the cone crusher but also creates an additional burden for the production of subsequent products. Therefore, we propose a cone crusher discharge particle size limiting and adjusting device to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a cone mill discharge particle size limiting and adjusting device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cone mill discharge particle size limiting and adjusting device, comprising a mounting frame and a cone mill, wherein a mounting box is fixedly mounted on the mounting frame, the upper part of the mounting box is correspondingly arranged with the discharge port of the cone mill, and a discharge port is opened at the bottom of the mounting box, a rotating frame is rotatably mounted inside the mounting box, a screen frame is fixedly mounted on the rotating frame, a third toothed ring is sleeved on the rotating frame, a drive wheel is rotatably mounted inside the mounting box, the drive wheel is meshed with the third toothed ring, a discharge pipe is fixedly mounted inside the mounting box, and multiple sets of annularly distributed first closed plates are provided inside the discharge pipe, a hopper is fixedly mounted above the mounting frame, and a discharge seat is fixedly mounted at the lower end of the hopper.
[0006] As a further preferred embodiment of this technical solution, the lower end of the screen frame is rotatably connected to the upper end of the discharge pipe, a first mounting ring is rotatably installed inside the discharge pipe, and multiple sets of the first closing plates are rotatably connected to the discharge pipe through the first mounting shaft.
[0007] As a further preferred embodiment of this technical solution, a first toothed ring is sleeved on the first mounting ring, and a first gear is sleeved on each of the multiple sets of the first mounting shafts, with each of the multiple sets of the first gear meshing with the first toothed ring.
[0008] As a further preferred embodiment of this technical solution, the feeding seat is correspondingly arranged with the feed hopper of the cone mill, and the mounting frame is provided with a conveying pipe, the two ends of which are fixedly connected to the discharge pipe and the hopper, respectively.
[0009] As a further preferred embodiment of this technical solution, the mounting frame is equipped with a dust collector and a Roots vacuum pump. The air inlet of the Roots vacuum pump is connected to the outlet of the dust collector via an air pipe, and the inlet of the dust collector is sealed to the silo via an air pipe.
[0010] As a further preferred embodiment of this technical solution, a second mounting ring is rotatably installed inside the feeding seat, and a second toothed ring is sleeved on the second mounting ring. The feeding seat is provided with multiple sets of annularly distributed second closing plates.
[0011] As a further preferred embodiment of this technical solution, multiple sets of the second closing plates are rotatably connected to the feed seat via the second mounting shaft, and multiple sets of the second mounting shaft are fitted with second gears, and multiple sets of the second gears are meshed with the second gear ring.
[0012] This utility model provides a device for adjusting the discharge particle size of a cone mill, which has the following advantages:
[0013] (1) This utility model uses the rotating frame to drive the screen frame to rotate in the installation box to screen the material crushed by the cone mill. The material that meets the crushing standard passes through the holes of the screen frame and is discharged through the discharge port at the bottom of the installation box. Some material that cannot pass through the screen frame and does not meet the crushing standard remains on the screen frame. Since the screen frame is inverted cone-shaped, the material that cannot be discharged under gravity is concentrated at the bottom of the screen frame, i.e. the end of the discharge pipe. Under the action of the first closing plate, it remains on multiple sets of first closing plates. When multiple sets of first closing plates in the discharge pipe open simultaneously, the larger materials can be discharged. The size of the holes of the screen frame is the limit of the discharge particle size of the material after being crushed by the cone mill. The screening standard of the screen frame can be changed according to the actual cone mill and the processing standard of the material. This effectively realizes the limitation and adjustment of the discharge particle size of the cone mill, and avoids the uniform discharge of all materials with different particle sizes, which will affect the product production quality in the subsequent material processing process, and require the staff to re-screen, which increases the work steps and increases the workload.
[0014] (2) The present invention connects the air inlet of the Roots vacuum pump to the outlet of the dust collector through the air pipe, and the inlet of the dust collector is sealed to the silo through the air pipe to form a negative pressure suction system. The material that does not meet the screening standard and enters the discharge pipe of the installation box is collected back into the silo through the conveying pipe. The material is then re-inputted into the cone mill and crushed through the unified opening and closing of multiple sets of second closing plates in the material feeding seat below the silo. This reciprocating conveying and reprocessing method ensures the working quality of the cone mill and eliminates the need for workers to screen materials and manually transport, feed and crush them again. This reduces the number of working steps, improves work efficiency and ensures the quality of the output. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0023] This utility model provides a technical solution: such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in this embodiment, a cone mill discharge particle size limiting and adjusting device includes a mounting frame 1 and a cone mill 3. A mounting box 2 is fixedly mounted on the mounting frame 1. The upper part of the mounting box 2 is corresponding to the discharge port of the cone mill 3. A discharge port 25 is opened at the bottom of the mounting box 2. A rotating frame 4 is rotatably mounted inside the mounting box 2. A screen frame 5 is fixedly mounted on the rotating frame 4. A third toothed ring 6 is sleeved on the rotating frame 4. A drive wheel 7 is rotatably mounted inside the mounting box 2. The drive wheel 7 is meshed with the third toothed ring 6. A discharge pipe 8 is fixedly mounted inside the mounting box 2. Multiple sets of annularly distributed first closed plates 10 are provided inside the discharge pipe 8. A material feed tube is fixedly mounted above the mounting frame 1. The lower end of the hopper 15 is fixedly equipped with a feeding seat 19. The lower end of the screen frame 5 is rotatably connected to the upper end of the discharge pipe 8. A first mounting ring 9 is rotatably installed inside the discharge pipe 8. Multiple sets of first closing plates 10 are rotatably connected to the discharge pipe 8 through first mounting shafts 11. A first toothed ring 12 is sleeved on the first mounting ring 9. A first gear 13 is sleeved on multiple sets of first mounting shafts 11. Multiple sets of first gears 13 are meshed with the first toothed ring 12. The motor in the mounting box 2 drives the drive wheel 7 to rotate, which, in conjunction with the third toothed ring 6, causes the rotating frame 4 to drive the screen frame 5 to rotate in the mounting box 2. The material crushed by the cone mill 3 falls uniformly into the... In the screen frame 5, the materials are screened during rotation. Materials that meet the crushing standard pass through the holes of the screen frame 5 and are discharged through the discharge port 25 below the mounting box 2. Some materials that cannot pass through the screen frame 5 and do not meet the crushing standard remain on the screen frame 5. Since the screen frame 5 is inverted cone-shaped, materials that cannot be discharged under gravity are concentrated at the bottom of the screen frame 5, i.e., the end of the discharge pipe 8. Under the action of the first closing plate 10, they remain on multiple sets of first closing plates 10. When the motor in the discharge pipe 8 drives the first mounting shaft 11 to rotate, it drives the first gear 13 to rotate synchronously, cooperating with multiple sets of first gears 1 The first toothed ring 12 and the first mounting ring 9 enable multiple sets of first closing plates 10 to rotate synchronously. After opening the upper end of the discharge pipe 8, larger materials can be discharged. The size of the mesh size of the screen frame 5 is the limit for the output particle size of the material after being crushed by the cone mill 3. The screening standard of the screen frame 5 can be changed according to the actual cone mill 3 and the processing standard of the material, effectively realizing the limitation and adjustment of the output particle size of the cone mill 3. This avoids the uniform discharge of all materials with different particle sizes, which would affect the product quality in the subsequent material processing process, requiring the staff to re-screen, increasing the work steps and workload.
[0024] like Figure 5 and Figure 6As shown, the feeding seat 19 is correspondingly arranged with the feed hopper of the cone mill 3. The mounting frame 1 is equipped with a conveying pipe 14, and the two ends of the conveying pipe 14 are fixedly connected to the discharge pipe 8 and the hopper 15, respectively. The mounting frame 1 is equipped with a dust collector 16 and a Roots vacuum pump 18. The air inlet of the Roots vacuum pump 18 is connected to the outlet of the dust collector 16 through an air pipe 17, and the inlet of the dust collector 16 is sealed to the hopper 15 through an air pipe 17. A second mounting ring 20 is rotatably installed inside the feeding seat 19, and a second toothed ring 23 is sleeved on the second mounting ring 20. The feeding seat 19 is equipped with multiple sets of annularly distributed second closing plates 21. The multiple sets of second closing plates 21 are rotatably connected to the feeding seat 19 through a second mounting shaft 22. A second gear 24 is sleeved on each of the multiple sets of second mounting shafts 22. All wheels 24 are meshed with the second toothed ring 23. The air inlet of the Roots vacuum pump 18 is connected to the outlet of the dust collector 16 through the air pipe 17. The inlet of the dust collector 16 is sealed to the hopper 15 through the air pipe 17, forming a negative pressure suction system. The material that does not meet the screening standard and enters the discharge pipe 8 of the installation box 2 is collected back into the hopper 15 through the conveying pipe 14. The material is then re-input into the cone mill 3 and crushed by the unified opening and closing of multiple sets of second closing plates 21 in the discharge seat 19 below the hopper 15. This reciprocating conveying and reprocessing method ensures the working quality of the cone mill 3 and eliminates the need for workers to screen materials and manually transport, feed, and crush them again. This reduces the number of working steps, improves work efficiency, and ensures the quality of the output.
[0025] This utility model provides a cone crusher discharge particle size limiting and adjustment device. The specific working principle is as follows: The motor in the mounting box 2 drives the drive wheel 7 to rotate, which, in conjunction with the third toothed ring 6, causes the rotating frame 4 to drive the screen frame 5 to rotate within the mounting box 2. The material crushed by the cone crusher 3 falls uniformly into the screen frame 5. During the rotation of the screen frame 5, these materials are screened. Materials that meet the crushing standard pass through the holes of the screen frame 5 and are discharged through the discharge port 25 below the mounting box 2. Some materials that cannot pass through the screen frame 5 and do not meet the crushing standard remain on the screen. On the screen frame 5, because the screen frame 5 is inverted conical, materials that cannot be discharged under gravity are concentrated at the bottom of the screen frame 5, that is, the end of the discharge pipe 8. Under the action of the first closing plate 10, they remain on multiple sets of first closing plates 10. When the motor in the discharge pipe 8 drives the first mounting shaft 11 to rotate, it drives the first gear 13 to rotate synchronously. With the cooperation of multiple sets of first gears 13, first gear rings 12, and first mounting rings 9, multiple sets of first closing plates 10 are rotated synchronously. After opening the upper end of the discharge pipe 8, these larger materials can be discharged. The size of the aperture of the screen frame 5 is the size of the aperture for materials passing through a circular... The cone mill 3 limits the output particle size of the crushed material. The screening standard of the screen frame 5 can be changed according to the actual cone mill 3 and the processing standard of the material. This effectively limits and adjusts the output particle size of the cone mill 3, preventing the uniform discharge of materials with different particle sizes, which would affect the product quality during subsequent material processing and require re-screening by workers, increasing the workload and steps. The air inlet of the Roots vacuum pump 18 is connected to the outlet of the dust collector 16 through the air pipe 17, and the inlet of the dust collector 16 is connected to the hopper 15 through the air pipe 17. The sealed connection forms a negative pressure suction system. The material that does not meet the screening standard and enters the discharge pipe 8 of the installation box 2 is collected back into the hopper 15 through the conveying pipe 14. The material is then fed back into the cone mill 3 for crushing through the unified opening and closing of multiple sets of second closing plates 21 in the discharge seat 19 below the hopper 15. This reciprocating conveying and reprocessing method ensures the working quality of the cone mill 3 and eliminates the need for workers to screen materials and manually transport, feed, and crush them again. This reduces the number of work steps, improves work efficiency, and ensures the quality of the output.
