Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to an anti-clogging vibrator and a neodymium iron boron coarse powder siphon conveying device. Background Technology

[0002] In the production of NdFeB coarse powder, for processes with height differences, a siphon method can be used to transport materials. The siphon tube sucks in the particles to achieve feeding. However, due to the gravity of the particles and their accumulation, and the fact that the inlet of the siphon tube is located at the bottom of the hopper, the material is easily compacted, causing difficulties in suction and blockage. Furthermore, a separate anti-blocking structure needs to be set at the discharge port of the siphon tube to ensure smooth material discharge. There is room for improvement in the anti-blocking technology for conveying NdFeB coarse powder in the existing technology.

[0003] To address this, we propose an anti-clogging vibrator and a neodymium iron boron coarse powder siphon conveying device. Utility Model Content

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an anti-clogging vibrator, comprising:

[0006] The bracket is provided with a protective structure for buffering. The protective structure includes a clamping block, a buffer block and a deformation groove. A clamping block is fixedly installed on one side of the bracket, and another identical detachable clamping block is provided on one side of the clamping block. The two clamping blocks together clamp and limit the buffer block. The buffer block has several deformation grooves for deformation.

[0007] A vibration structure is installed below the support to generate vibration.

[0008] In a preferred embodiment of this utility model, the clamping block forms an arc-shaped plate, and both ends of the clamping block are provided with integrally formed ear plates.

[0010] In a preferred embodiment of this utility model, the buffer block is formed into an annular block, and the clamping groove is an arc-shaped groove. The clamping grooves on the inner walls of the two clamping blocks together form an annular groove that is interference-fitted with the buffer block. After the two clamping blocks are closed, the buffer block is limited to the clamping groove.

[0011] In a preferred embodiment of this utility model, the deformation groove is a fan-shaped groove that penetrates the buffer block. Multiple deformation grooves are arranged in a circular array at the ends of the buffer block, and a deformable rib is formed between two adjacent deformation grooves.

[0012] In a preferred embodiment of this utility model, the vibration structure includes a mounting base and a vibration motor, wherein the vibration motor is fixedly mounted on the top of the mounting base.

[0013] A neodymium iron boron coarse powder siphon conveying device includes a material box and a siphon pipe. The material box has a cavity, and the end of the siphon pipe is located inside the material box cavity. All of the above-mentioned anti-clogging vibrators are provided on one side of the material box. The bracket is fixedly installed on the outer wall of the material box. The siphon pipe passes through the central hole of the buffer block, and the mounting base is fixedly installed on the siphon pipe.

[0014] In a preferred embodiment of this utility model, an air pipe is fixedly installed on the outer wall of the siphon tube, the air pipe obliquely penetrates the siphon tube and extends into the interior of the siphon tube, and the air pipe is connected to an air source.

[0015] This utility model provides an anti-clogging vibrator and a NdFeB coarse powder siphon conveying device. It has the following beneficial effects:

[0016] 1. This anti-clogging vibrator and neodymium iron boron coarse powder siphon conveying device, by passing the siphon tube through the central hole of the buffer block and placing the siphon tube between two clamping blocks, and locking the ear plates of the two clamping blocks with bolts and nuts, the buffer block is locked and limited into the clamping groove. Through the rubber buffer block and multiple deformation grooves, the siphon tube can vibrate within a certain range without affecting the connection with the clamping groove, realizing the elastic connection between the siphon tube and the clamping groove. The clamping blocks can be fixed by welding to the bracket, and the bracket is installed with bolts to the material box, which greatly reduces the probability of material blockage at the inlet and outlet of the siphon tube.

[0025] A clog-resistant vibrator and a neodymium iron boron coarse powder siphon conveying device, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes:

[0026] The bracket 10 has a protective structure for cushioning, which includes clamping blocks 11, buffer blocks 13, and deformation grooves 14. One clamping block 11 is fixedly installed on one side of the bracket 10, and another identical, detachable clamping block 11 is provided on one side of the clamping block 11. The two clamping blocks 11 together clamp and limit the buffer block 13. The buffer block 13 has several deformation grooves 14 for deformation. The clamping blocks 11 form arc-shaped plates, and both ends of the clamping blocks 11 have integrally formed ear plates with mounting holes. Bolts are installed in the mounting holes to lock the two clamping blocks 11 together. The protective structure also includes... The inner circumferential surface of the clamping block 11 is provided with a clamping groove 12. The buffer block 13 is installed in the clamping groove 12 and forms an annular block. The clamping groove 12 is an arc-shaped groove. The clamping grooves 12 on the inner walls of the two clamping blocks 11 together form an annular groove that is interference-fitted with the buffer block 13. After the two clamping blocks 11 are closed, the buffer block 13 is limited in the clamping groove 12. The deformation groove 14 is a fan-shaped groove that penetrates the buffer block 13. Multiple deformation grooves 14 are distributed in a ring array at the end of the buffer block 13. A deformable rib is formed between two adjacent deformation grooves 14.

[0027] In this scheme, the siphon tube 31 used for conveying materials generates amplitude, and the vibration of the siphon tube 31 is used to suppress material blockage at the inlet and outlet of the siphon tube 31. By passing the siphon tube 31 through the central hole of the buffer block 13, the siphon tube 31 is placed between two clamping blocks 11, and the ear plates of the two clamping blocks 11 are locked with bolts and nuts. Then, the buffer block 13 is locked and limited to the clamping groove 12. Through the rubber buffer block 13 and multiple deformation grooves 14, the siphon tube 31 can vibrate within a certain range without affecting the connection with the clamping groove 12, realizing the elastic connection between the siphon tube 31 and the clamping groove 12. The clamping blocks 11 can be fixed by welding to the bracket 10, and the bracket 10 is installed with bolts to the material box 30, which greatly reduces the probability of material blockage at the inlet and outlet of the siphon tube 31. There is no need to set up a separate anti-blocking structure at the inlet and outlet of the siphon tube 31, and the overall structure is simplified.

[0028] like Figure 1 As shown, the vibration structure is installed below the support 10 to generate vibration;

[0029] The vibration structure includes a mounting base 20 and a vibration motor 21. The vibration motor 21 is fixedly mounted on the top of the mounting base 20. The mounting base 20 can be locked to the siphon tube 31 by a flange or directly welded. By connecting the vibration motor 21 to the power supply, the siphon tube 31 vibrates, forming an elastic connection between the siphon tube 31 and the material box 30. The high-frequency vibration of the siphon tube 31 prevents material blockage.

[0030] like Figure 4 and Figure 5 As shown, a neodymium iron boron coarse powder siphon conveying device includes a material box 30 and a siphon pipe 31. The material box 30 has a cavity, and the end of the siphon pipe 31 is located inside the cavity of the material box 30. All the aforementioned anti-clogging vibrators are provided on one side of the material box 30. The bracket 10 is fixedly installed on the outer wall of the material box 30. The siphon pipe 31 passes through the central hole of the buffer block 13. The mounting base 20 is fixedly installed on the siphon pipe 31. By setting the above structure, the probability of coarse particles clogging the siphon pipe 31 can be reduced during the material conveying process. Since the siphon pipe 31 is vibrating as a whole, the material can maintain good flowability at both the inlet and outlet of the siphon pipe 31 and inside the siphon pipe 31, greatly reducing the probability of material blockage. Since the anti-clogging vibrators are located outside the siphon pipe 31, it is also convenient for inspection and maintenance.

[0031] like Figure 1 and Figure 5As shown, an air pipe 32 is fixedly installed on the outer wall of the siphon 31. The air pipe 32 obliquely penetrates the siphon 31 and extends into the interior of the siphon 31. The air pipe 32 is connected to an air source. As a supplement to the above scheme, by connecting the air pipe 32 to the air source, taking a gas cylinder storing nitrogen as an example, a stream of air is sprayed into the lower end of the siphon 31 through the oblique air pipe 32. Under the action of the flow rate difference, the coarse particles are promoted to flow towards the end of the siphon 31, which can also prevent material blockage. Secondly, the particles are surrounded by nitrogen during the conveying process, forming a relatively isolated environment and inhibiting the oxidation of the particles.

[0032] The working principle of this utility model is as follows: The siphon tube 31 is passed through the central hole of the buffer block 13, and then placed between two clamping blocks 11. The ear plates of the two clamping blocks 11 are locked in place using bolts and nuts, thereby locking and limiting the buffer block 13 into the clamping groove 12. Through the rubber buffer block 13 and multiple deformation grooves 14, the siphon tube 31 can vibrate within a certain range without affecting its connection with the clamping groove 12, achieving an elastic connection between the siphon tube 31 and the clamping groove 12. The clamping blocks 11 can be welded to the bracket 10. The bracket 10 is fixed by bolts to the material box 30. By connecting the vibrating motor 21 to the power supply, the siphon tube 31 vibrates. The air pipe 32 is connected to the air source. Taking a gas cylinder storing nitrogen as an example, a bundle of airflow is sprayed into the lower end of the siphon tube 31 through the inclined air pipe 32. Under the action of the flow rate difference, the coarse particles are promoted to flow towards the end of the siphon tube 31. During the conveying process, the particles are surrounded by nitrogen to form a relatively isolated environment, which inhibits the oxidation of the particles. The material mentioned in the text is neodymium iron boron coarse powder.
