Description

Technical Field

[0001] This utility model relates to the technical field of crushing and grinding equipment, specifically to an ultrafine crushing and grinding equipment. Background Technology

[0002] Ultrafine grinding technology refers to the process of pulverizing materials to micron or even nanometer-sized particles using mechanical force, heat, chemical force, or other methods. Due to their unique physicochemical properties, ultrafine powder materials have wide applications in many fields, such as chemical engineering, pharmaceuticals, food processing, materials science, and mining.

[0003] A search revealed a utility model patent with Chinese patent publication number CN220590229U, which discloses an ultrafine grinding and pulverizing device for traditional Chinese medicine. This device belongs to the field of traditional Chinese medicine processing technology and addresses the problem of poor grinding and pulverizing effects in existing technologies. The device includes a first chamber and a second chamber, with the second chamber fixed to the top of the first chamber. The first and second chambers are connected. A lid is provided on the top of the second chamber, and a U-shaped fixing frame is fixed to the top of the lid. A hydraulic rod is fixedly installed in the middle of the top of the U-shaped fixing frame.

[0004] The aforementioned device achieves material crushing by setting up crushing blades. However, as more material is crushed, these powders inevitably obstruct larger particles, preventing the crushing blades from directly contacting the material. This results in the material being completely crushed taking longer, indicating room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide an ultrafine grinding and pulverizing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ultrafine grinding and pulverizing device, comprising a base frame, a grinding tank fixedly installed inside the base frame, a filter assembly installed at the bottom of the grinding tank, the filter assembly comprising a mounting sleeve rotatably fitted at the bottom of the grinding tank, a filter screen disposed inside the mounting sleeve, a guide frame fixedly connected to the outer wall of the bottom of the mounting sleeve, an inclined bucket disposed outside the guide frame, a motor fixedly installed on the inner wall of the bottom of the base frame, a drive structure mounted outside the output end of the motor, and the drive structure comprising an extension plate, two extension rods, a spring, a mounting column, and two striking heads.

[0007] As a further preferred embodiment of this technical solution, the extension plate is fixedly connected to the bottom of the outer circumference of the guide frame, the motor output end is fixedly connected to two horizontally arranged extension rods, the two striking heads are respectively fixed to the ends of the two extension rods that are far apart from each other, the mounting column is fixedly connected to the inner wall of the bottom of the base frame, and the spring is fixedly connected between the extension plate and the mounting column.

[0008] During the crushing process, suitable powder can be separated in a timely manner without affecting the crushing of larger materials. It also enables continuous processing, which helps to improve processing efficiency. The extension rod rotates synchronously with the motor output end. Then, the end of the extension rod will contact the extension plate. The striking head pushes the guide frame a small distance through the extension plate, and the spring will also be stretched due to the external force. After that, the spring returns to its length and pulls the extension plate back to its original position. This process repeats, and the guide frame will drive the mounting sleeve to swing rapidly. Qualified powder will quickly pass through the filter screen holes and fall downwards, preventing these powders from affecting the crushing process.

[0009] As a further preferred embodiment of this technical solution, a feeding assembly is installed on the top of the crushing tank. The feeding assembly includes a connecting plate fixedly connected to the outer wall of the top of the crushing tank. A storage chamber is fixedly installed on the outer wall of the top of the connecting plate, and a cover is provided on the top of the storage chamber.

[0011] Grasp the baffle and push it to one side. The discharge hole inside will align with the outlet of the storage chamber. The material will flow down the storage chamber. When the crushing tank reaches its capacity, pull the baffle back to its original position. The discharge port of the storage chamber will then be sealed. After processing is complete, pulling the baffle again can achieve rapid feeding or slow feeding by reducing the opening at the bottom of the storage chamber, ensuring continuous processing of the device.

[0012] As a further preferred embodiment of this technical solution, a grinding assembly is installed inside the base frame. The grinding assembly includes a mounting ring fixedly installed inside the base frame. A grinding ring is coaxially fixed to the top of the inner circumference of the mounting ring. A motor is fixedly installed to the bottom outer wall of the mounting ring, and a grinding block adapted to the grinding ring is coaxially fixed to the output end of the motor.

[0013] As a further preferred embodiment of this technical solution, a crushing blade is coaxially fixed at the top of the motor output end, and two inclined guide blades are fixedly connected to the motor output end, with both guide blades positioned above the filter screen.

[0014] As a further preferred embodiment of this technical solution, the striking head is made of rubber material.

[0015] This utility model provides an ultrafine grinding and pulverizing device, which has the following beneficial effects:

[0016] (1) By setting up a filter assembly, this utility model can separate the appropriate powder in time during the crushing operation, without affecting the crushing operation of larger materials, and can achieve continuous processing, which is conducive to improving processing efficiency. The extension rod rotates synchronously with the motor output end. Then the end of the extension rod will contact the extension plate. The striking head pushes the guide frame a small distance through the extension plate, and the spring will also be stretched due to the external force. Then the spring returns to its length and pulls the extension plate back to its original position. This process is repeated, and the guide frame will drive the mounting sleeve to swing quickly. The qualified powder will quickly pass through the filter screen and fall down, avoiding these powders from affecting the crushing operation.

[0017] (2) By setting up a feeding component, the baffle is grasped and pushed to one side, and the feeding hole inside is aligned with the outlet of the storage chamber. The material will flow down along the storage chamber. When the crushing tank reaches its capacity, the baffle is pulled back to its original position, and the outlet of the storage chamber will be closed. After the processing is completed, pulling the baffle again can achieve rapid feeding and slow feeding by adjusting the bottom opening of the storage chamber, so as to ensure that the device can process continuously.

[0023] 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.

[0024] This utility model provides a technical solution: such as Figure 2 , Figure 3As shown in Figure 4, in this embodiment, an ultrafine grinding and pulverizing device includes a base frame 1, a pulverizing tank 2 is fixedly installed inside the base frame 1, a filter assembly 6 is installed at the bottom of the pulverizing tank 2, the filter assembly 6 includes a mounting sleeve 601 rotatably fitted at the bottom of the pulverizing tank 2, a filter screen 602 is provided inside the mounting sleeve 601, a guide frame 603 is fixedly connected to the bottom outer wall of the mounting sleeve 601, an inclined bucket is provided outside the guide frame 603, a motor 3 is fixedly installed on the bottom inner wall of the base frame 1, a drive structure is installed outside the output end of the motor 3, and the drive structure includes an extension plate 604, two extension rods 605, a spring 606, a mounting column 607 and two striking heads 608.

[0025] The extension plate 604 is fixedly connected to the bottom of the outer circumference of the guide frame 603. The output end of the motor 3 is fixedly connected to two horizontally arranged extension rods 605. Two striking heads 608 are respectively fixed to the ends of the two extension rods 605 that are far apart from each other. The mounting column 607 is fixedly connected to the bottom inner wall of the base frame 1. The spring 606 is fixedly connected between the extension plate 604 and the mounting column 607.

[0026] The extension rod 605 rotates synchronously with the output end of the motor 3. Then, the end of the extension rod 605 contacts the extension plate 604. The striking head 608 pushes the guide frame 603 a small distance through the extension plate 604, and the spring 606 will also extend due to the external force. Then, the spring 606 returns to its length and pulls the extension plate 604 back to its original position. This process repeats, and the guide frame 603 will drive the mounting sleeve 601 to swing rapidly. Qualified powder will quickly pass through the filter screen 602 and fall downwards, preventing these powders from affecting the crushing process.

[0027] like Figure 1 As shown in Figure 2, a feeding assembly 7 is installed on the top of the crushing tank 2. The feeding assembly 7 includes a connecting plate 701 fixedly connected to the outer wall of the top of the crushing tank 2. A storage chamber 702 is fixedly installed on the outer wall of the top of the connecting plate 701. A cover is provided on the top of the storage chamber 702.

[0028] A baffle 703 is slidably inserted into the discharge port of the storage chamber 702, and a discharge hole 704 adapted to the discharge port of the storage chamber 702 is opened inside the baffle 703.

[0029] Grasp the baffle 703 and push it to one side. The discharge hole 704 inside it will align with the outlet of the storage chamber 702. The material will flow down along the storage chamber 702. When the capacity of the crushing tank 2 is reached, pull the baffle 703 back to its original position. The discharge port of the storage chamber 702 will be closed. After processing is completed, pulling the baffle 703 again can achieve rapid feeding and slow feeding by adjusting the bottom opening of the storage chamber 702, ensuring that the device can process continuously.

[0030] like Figure 1As shown, a grinding assembly 8 is installed inside the base frame 1. The grinding assembly 8 includes a mounting ring 801 fixedly installed inside the base frame 1. A grinding ring 802 is coaxially fixed to the top of the inner circumference of the mounting ring 801. A motor is fixedly installed on the bottom outer wall of the mounting ring 801, and a grinding block 803 adapted to the grinding ring 802 is coaxially fixed to the output end of the motor.

[0031] The powder falls from the outlet of the guide frame 603 into the grinding ring 802. Finally, the motor at the bottom of the mounting ring 801 is started, and the grinding block 803 is driven to rotate. The grinding ring 802 and the grinding block 803 work together to further refine the powder.

[0032] like Figure 2 As shown, a crushing blade 4 is coaxially fixed at the top of the output end of motor 3, and two inclined guide blades 5 are fixedly connected to the output end of motor 3, with both guide blades 5 positioned above the filter screen 602.

[0033] The motor 3 inside the base frame 1 is started. The motor 3 drives the crushing blade 4 to rotate rapidly, which crushes the material. At the same time, the guide blade 5 outside the output end of the motor 3 also rotates synchronously. The guide blade 5 can scoop up larger materials and lift them upwards. Then the materials will be cut by the crushing blade 4, and so on.

[0034] like Figure 4 As shown, the striking head 608 is made of rubber material. The striking head 608 can deform when subjected to external force, ensuring that the extension plate 604 can be touched by the striking head 608 while the extension plate 604 does not obstruct the movement of the striking head 608.

[0035] This utility model provides an ultrafine grinding and pulverizing device, the specific working principle of which is as follows:

[0036] When the device is working, grasp the baffle 703 and push it to one side. The discharge hole 704 inside aligns with the outlet of the storage chamber 702, and the material will flow downwards along the storage chamber 702. When the capacity of the crushing tank 2 is reached, pull the baffle 703 back to its original position, and the discharge port of the storage chamber 702 will be closed. After processing is completed, pulling the baffle 703 again can achieve rapid feeding, or slow feeding can be achieved by reducing the opening at the bottom of the storage chamber 702, ensuring continuous processing. Start the motor 3 inside the base frame 1. The motor 3 drives the crushing blade 4 to rotate rapidly, which crushes the material. At the same time, the guide blade 5 outside the output end of the motor 3 will also rotate synchronously. The guide blade 5 can scoop up larger materials and lift them upwards. Then the materials will be cut by the crushing blade 4, and so on. The extension rod 605 rotates synchronously with the output of motor 3. Then, the end of the extension rod 605 contacts the extension plate 604. The striking head 608 pushes the guide frame 603 a small distance through the extension plate 604, and the spring 606 extends due to the external force. Afterward, the spring 606 returns to its length, pulling the extension plate 604 back to its original position. This process repeats, causing the guide frame 603 to drive the mounting sleeve 601 to swing rapidly. Qualified powder will quickly pass through the filter screen 602 and fall downward, preventing it from affecting the grinding process. The powder falls from the outlet of the guide frame 603 into the grinding ring 802. Finally, the motor at the bottom of the mounting ring 801 is started, driving the grinding block 803 to rotate. The grinding ring 802 and the grinding block 803 work together to further refine the powder.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
