Description

Technical Field

[0001] This utility model relates to airflow pulverizer equipment technology, specifically a quick-release device for the hopper of an airflow pulverizer. Background Technology

[0002] An airflow pulverizer is a material pulverizer that uses high-speed airflow to entrain materials into a container and uses the impact and shearing force of the airflow to cause the materials to collide with each other, thus achieving material pulverization without mechanical parts.

[0003] For example, the publication (announcement) number: CN219187199U, publication (announcement) date: 2023-06-16, discloses a silicon micro powder air jet mill device, including a lower frame and a right frame and a left frame connected to the top thereon. A hopper is connected to the left frame through a vibration component. The output end of the hopper is connected to an air jet mill through a corrugated pipe. The output end of the air jet mill is connected to a dust collector connected to the right frame through a second connecting pipe and a first connecting pipe in sequence. The lower end of the dust collector is connected to an induced draft fan through a third connecting pipe.

[0004] The drawback of existing technology is that the hopper of an air jet mill typically needs to be disassembled and reassembled periodically to meet the processing requirements of different products, avoid cross-contamination of materials, and facilitate regular cleaning and maintenance. However, traditional hoppers are generally installed at a high position to allow materials to fall under their own weight, and the installation method is usually bolt-fixed. Therefore, the actual disassembly and reassembly rate is slow, and operational safety is also affected. Utility Model Content

[0005] The purpose of this invention is to provide a quick-release device for the hopper of an airflow pulverizer to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A quick-release device for the hopper of an airflow pulverizer includes a machine body with a hopper, a material pipe installed at the outlet of the hopper, and a conveying pipe installed on the machine body. The material pipe is inserted into the conveying pipe, and a ring plate is fixedly installed on the side wall of the material pipe. A connecting sleeve with a clamp on the outside of the ring plate is fixedly installed at the end of the conveying pipe. The connecting sleeve has multiple locking holes, and the ring plate has a protrusion that engages with the locking holes.

[0007] As a further description of the above technical solution: the connecting sleeve has an inner chamber for the axial sliding of the replacement plate.

[0008] As a further description of the above technical solution: the inner chamber port is provided with a sliding opening that engages with the protrusion.

[0009] As a further description of the above technical solution: a sliding track is provided between the sliding opening and the lock hole.

[0010] As a further description of the above technical solution: the protrusion is driven to slide circumferentially in the slide rail.

[0011] As a further description of the above technical solution: an elastic element located on the outside of the material tube is fixedly installed in the inner chamber.

[0012] As a further description of the above technical solution: a gasket that abuts against the ring plate is fixedly installed at the end of the elastic element.

[0013] As a further description of the above technical solution: a sealing bladder is fixedly installed on the gasket.

[0014] As a further description of the above technical solution: the sealing bladder is deformed under pressure and comes into contact with the joint between the ring plate and the inner chamber.

[0015] As a further description of the above technical solution: the sealing bladder is specifically an annular rubber bladder.

[0016] In the above technical solution, the quick-release device for the hopper of the airflow pulverizer provided by this utility model has the following beneficial effects: by vertically inserting the material tube into the conveying pipe, the installation and positioning before connection is achieved, and then the material tube is rotated until the hopper is aligned on the machine body. At this time, the ring plate is connected and sealed because it is attached to the inner wall of the machine body, while the circumferentially arranged protrusions enter from the sliding port, and then enter the locking hole from the slide upward by rotation. Conversely, the quick-release function of the material tube is obtained, which makes the hopper more able to meet the needs of disassembly, cleaning and maintenance, and ensures the safety of operation.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1-4 This utility model provides a technical solution, including the following embodiments: Example 1 Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment modifies the fixing method based on the original bolt fixing of the material hopper 11 outlet to achieve the purpose of quick assembly and disassembly of the material hopper 11. By vertically inserting the material tube 2 into the conveying tube 3, the installation positioning before connection is achieved. Then, the material tube 2 is rotated until the material hopper 11 is aligned on the machine body 1. At this time, the ring plate 21 is connected and sealed because it fits against the inner wall of the inner chamber 32. At the same time, the circumferentially arranged protrusions 22 enter from the sliding port 33, and then enter the locking hole 35 from the slide 34 by rotation. Conversely, the quick disassembly function of the material tube 2 is obtained, which makes the material hopper 11 more compliant with disassembly, cleaning and maintenance, and ensures operational safety.

[0022] Specifically, the material pipe 2 is welded to the discharge port of the hopper 11, and the material pipe 2 is quickly disassembled and assembled so that the hopper 11 can be quickly removed from the air jet mill.

[0023] Furthermore, the installed material pipe 2 can be directly inserted into the conveying pipe 3. Therefore, the direct-insertion material conveying can directly deliver the material from the conveying pipe 3 to the pneumatic conveying position, avoiding the problem of material leakage.

[0024] Furthermore, the inner chamber 32 is formed by opening the port of the connecting sleeve 31, and may have an annular chamber located outside the ring piece 21, so that the ring piece 21 can be inserted and rotated.

[0025] Furthermore, the conveying pipe 3 and the airflow acceleration component of the airflow pulverizer are arranged in a three-pronged configuration, which is existing technology and will not be described in detail here. The conveying pipe 3 is modified by adding a flange to the original pipeline, that is, the flange is replaced with a connecting sleeve 31 with an inner chamber 32.

[0026] Example 2 Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment details the locking mechanism for quick assembly and disassembly of the material tube 2 and the conveying tube 3. Through the port of the sliding opening 33 located within the inner chamber 32, during the installation of the material tube 2, the protrusion 22 can be quickly inserted into the sliding opening 33 and moved downwards. The elastic element 4 deforms and stores force during the downward pressure applied by the ring plate 21. After the protrusion 22 reaches the bottom of the sliding opening 33, it rotates circumferentially until it reaches the port of the locking hole 35. At this point, the elastic element 4 returns to its original shape and pushes the ring plate 21 upwards, allowing the protrusion 22 to reach the bottom of the locking hole 35 for locking. Therefore, the assembly and disassembly of the material tube 2 is simpler and more convenient. Furthermore, the protrusion 22 within the locking hole 35 is still subjected to the pressure stored by the deformed elastic element 4, resulting in a better locking state.

[0027] Specifically, the elastic element 4 is a spring, and the elastic element 4 has not exceeded the deformation coefficient when the protrusion 22 reaches the position of the slide 34, and the depth of the lock hole 35 is less than the depth of the slide 33. Therefore, the elastic element 4, which returns to its upward position, always has elastic pressure.

[0028] Furthermore, the gasket 41 installed at the end of the elastic member 4 is an annular metal sheet, and the sealing bladder 42 transmits power to the annular piece 21 during the pressure applied to the gasket 41 so that the protrusion 22 can perform locking work.

[0029] Example 3 Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment details the sealing function of the material pipe 2 and the conveying pipe 3. After the ring plate 21 is pressed down and placed in the locked position, the sealing bladder 42 is deformed under pressure. One side deforms and accumulates at the insertion position of the material pipe 2 and the conveying pipe 3, so that the inner side of the annular sealing bladder 42 covers and seals the joint at the conveying position, ensuring that no material leaks after the material pipe 2 and the conveying pipe 3 are inserted; the other side accumulates at the vertical joint between the ring plate 21 and the connecting sleeve 31, so that the joint between the ring plate 21 and the connecting sleeve 31 is covered and sealed, ultimately achieving a double sealing effect.

[0030] Specifically, the sealing bladder 42 is bonded to the gasket 41, and the sealing bladder 42, like the gasket 41, is arranged in a ring shape. The sealing bladder 42 can achieve the function of deformation on both sides by using a hollow structure, so that the material pipe 2 and the conveying pipe 3 have a double sealing function, effectively preventing material leakage, while also intercepting dust intrusion and avoiding dust interference with the material conveying.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
