Description

Technical Field

[0001] This utility model relates to the field of metal particle screening technology, and in particular to a metal particle retrieval device. Background Technology

[0002] In the mass production and quality inspection of metal particles (such as titanium alloys and alloy steels), existing technologies often employ solutions of specific densities for screening. By preparing solutions tailored to the acceptable density range of the particles, particles of different densities are separated in batches due to differences in buoyancy, resulting in floating, suspended, or sinking states. These specific solutions exhibit diverse properties, potentially being acidic, neutral, or highly saline (e.g., high-concentration salt solutions, multi-component mixed solvents), and are widely used in particle classification and screening in metal processing, precision casting, and other fields.

[0003] During the screening process described above, tools are needed to scoop up particles in different states. Currently, the industry mostly uses ordinary strainers or simple scoops, which have the following drawbacks: Firstly, wear is a significant issue: when retrieving particles from the bottom, the bottom of the tool comes into direct contact with the bottom wall of the container holding the solution (such as a plastic or ceramic container), and frequent friction can easily lead to wear on both. At the same time, the movement, collision, or friction of the particles inside the tool can cause damage to the surface of the particles, affecting the precision of the product.

[0004] Secondly, poor adaptability to solutions: Since screening solutions may be acidic, neutral or highly saline, ordinary tool materials (such as ordinary metals and plastics) are easily corroded by solutions (such as electrochemical corrosion of high-salt solutions and swelling effect of specific solutions), which leads to a shortened tool life and even contamination of the solution or particles.

[0005] Third, solution adhesion affects efficiency: the surface smoothness of ordinary tools is insufficient, and solution residue is easy to adhere, resulting in the particles carrying excess solution when they are removed, which increases the burden on subsequent cleaning and drying steps.

[0006] Therefore, it is extremely important to provide a dedicated retrieval device that is adapted to the screening process of solutions with specific densities, and to solve the problems of wear, solution adaptability and solution adhesion. Utility Model Content

[0007] The purpose of this invention is to provide a metal particle retrieval device that solves the problems of wear between the metal particles and the tool, wear between the tool and the container, and insufficient adaptability of the tool to solutions with different properties in existing retrieval tools.

[0008] The objective of this utility model is achieved through the following technical solution: A metal particle scooping device includes a handle and a main ladle body; The main spoon body has a plurality of sieve holes distributed on its surface. The bottom of the main spoon body is flat, and the top and the side away from the handle of the main spoon body are open. The inner side of the main spoon body is provided with a first buffer anti-wear layer and a first corrosion resistant layer in sequence from the direction away from the main spoon body to the direction close to the main spoon body. The first buffer anti-wear layer is made of a low surface energy material. The outer side of the main spoon body is provided with a second buffer anti-wear layer and a second corrosion-resistant layer in sequence from the direction away from the main spoon body to the direction close to the main spoon body; The edges of the first buffer wear-resistant layer, the first corrosion-resistant layer, the main spoon body, the second buffer wear-resistant layer, and the second corrosion-resistant layer are sealed together by the third corrosion-resistant layer.

[0009] Preferably, both the first and second buffer wear-resistant layers are made of modified fluororubber with a thickness of 0.5-1 mm; the modified fluororubber is obtained by fluorination treatment of the surface of fluororubber.

[0010] Preferably, the first corrosion-resistant layer, the second corrosion-resistant layer and the third corrosion-resistant layer are all made of polytetrafluoroethylene coating, and the thickness of each layer is 0.1-0.3 mm.

[0011] Preferably, the main spoon body is made of 316 stainless steel with a thickness of 2-3mm.

[0012] Preferably, the edges of the sieve holes are rounded with a radius of 0.2-0.5 mm; the first buffer wear-resistant layer, the first corrosion-resistant layer, the second buffer wear-resistant layer, and the second corrosion-resistant layer on the inner wall of the sieve holes all form a continuous sealing structure through the third corrosion-resistant layer.

[0013] Preferably, the aperture of the sieve is 1-3 mm.

[0014] Preferably, two L-shaped limiting blocks are provided on the side of the main spoon body away from the handle, and a limiting groove is formed between the L-shaped limiting blocks and the side of the main spoon body away from the handle. A baffle is detachably provided in the limiting groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a first buffer anti-wear layer inside the main spoon body, the elasticity of the first buffer anti-wear layer can be used to buffer the shaking and collision of particles during the retrieval process, reducing scratches on the particle surface; at the same time, its low surface energy characteristics reduce the amount of solution adhering to the surface, reducing the amount of solution carried by the particles when they are taken out.

[0016] By setting a second buffer anti-wear layer on the outside of the main spoon body, the friction between the outside of the main spoon body and the container can be reduced when scooping up particles from the bottom, thus extending the service life of the container and the device.

[0017] By setting a first corrosion-resistant layer, a second corrosion-resistant layer, and a third corrosion-resistant layer, the chemical stability of the corrosion-resistant layer, which is resistant to acid and high salt, can be utilized to isolate the main spoon body from direct contact with the screening solution, making it particularly suitable for screening environments containing acid and high concentrations of salt.

[0018] By sealing the edges of each layer with a third corrosion-resistant layer, a continuous and seamless sealing structure is formed, preventing the solution from seeping into the surface of the main spoon body from the gaps between the layers and avoiding the failure of stainless steel due to localized corrosion.

[0019] This invention addresses the problems of wear, poor solution adaptability, solution adhesion, and particle slippage in existing technologies through the synergistic effect of the aforementioned multi-layered structure. Attached Figure Description

Detailed Implementation

[0021] Example 1 A metal particle retrieval device, such as Figure 1 As shown, it includes a handle 2 and a main spoon body 1; as Figure 1-2 As shown, the main spoon body 1 has several sieve holes 3 distributed on its surface. The bottom of the main spoon body 1 is flat, and the top and the side away from the handle 2 of the main spoon body 1 are open. Figure 1 and Figure 2 As shown, the inner side of the main spoon body 1 is provided with a first buffer anti-wear layer 4 and a first corrosion resistant layer 5 in sequence from the direction away from the main spoon body 1 to the direction close to the main spoon body 1. The first buffer anti-wear layer 4 is made of a low surface energy material. like Figure 1-2 As shown, the outer side of the main spoon body 1 is provided with a second buffer anti-wear layer 6 and a second corrosion-resistant layer 7 in sequence from the direction away from the main spoon body 1 to the direction close to the main spoon body 1; the edges of the first buffer anti-wear layer 4, the first corrosion-resistant layer 5, the main spoon body 1, the second buffer anti-wear layer 6, and the second corrosion-resistant layer 7 are sealed together by a third corrosion-resistant layer 8.

[0022] The first and second buffer wear-resistant layers 4 and 6 are both made of modified fluororubber with a thickness of 0.5-1 mm. The modified fluororubber is obtained by fluorination treatment of the fluororubber surface. During actual retrieval, it is crucial to minimize solution adsorption; otherwise, it will severely affect the remaining amount of solution of a specific density, hindering screening. While ordinary fluororubber is wear-resistant, its surface energy remains relatively high, making it prone to solution adhesion. Fluorination treatment (in existing technology) significantly reduces surface energy, effectively decreasing solution adhesion.

[0023] Furthermore, the first corrosion-resistant layer 5, the second corrosion-resistant layer 7, and the third corrosion-resistant layer 8 are all made of polytetrafluoroethylene (PTFE) coating, with a thickness of 0.1-0.3 mm. PTFE has better chemical corrosion resistance than most coatings and can withstand solution environments with pH 2-12 (covering acidic, neutral, and weakly alkaline screening solutions). At the same time, its low surface energy characteristics can help reduce solution adhesion.

[0024] Furthermore, the main spoon body 1 is made of 316 stainless steel with a thickness of 2-3mm.

[0025] Furthermore, the aperture of the sieve hole 3 is 1-3 mm.

[0026] Working Principle: Metal particles are placed in a container filled with a solution of a specific density. After standing for a while, the floating, suspended, or sunken metal particles are successively scooped out and placed in a designated location. During scooping, the operator holds the handle 2 and uses the main ladle body 1 to scoop up the metal particles. During the scooping process, the solution of the specific density leaks through the sieve holes 3 and falls into the container as much as possible. Because the inner side of the main ladle body 1 is equipped with a first buffer anti-wear layer 4, the elasticity of the modified fluororubber can buffer the shaking and collision of the metal particles inside the main ladle body 1, reducing scratches on the particle surface; at the same time, its low surface energy characteristics reduce the amount of solution adhering to the surface, reducing the amount of solution carried by the particles when they are taken out. When scooping up sunken particles, because the outer side of the main ladle body 1 is equipped with a second buffer anti-wear layer 6, the friction between the outer side of the main ladle body 1 and the container can be reduced when scooping up sunken particles, extending the service life of the container and the device.

[0027] Example 2 Based on Example 1, the edges of the sieve holes 3 are rounded with a radius of 0.2-0.5 mm; for example... Figure 2 As shown, the first buffer wear-resistant layer 4, the first corrosion-resistant layer 5, the second buffer wear-resistant layer 6, and the second corrosion-resistant layer 7 on the inner wall of the sieve hole 3 all form a continuous sealing structure through the third corrosion-resistant layer 8. In this design, the rounded corners eliminate the sharpness of the edges of the sieve hole 3, preventing particles from being scratched when passing through. The sealing structure of the inner wall of the sieve hole 3 prevents the solution from seeping into the main spoon body 1 from the sieve hole 3, ensuring that the overall sealing performance is not compromised.

[0028] In this invention, the purpose of scooping is achieved through an opening design on the main spoon body 1. However, because the opening on the side wall can easily cause particles to slip off, the scooping efficiency is reduced. Therefore, as... Figure 3-4 As shown, two L-shaped limiting blocks 9 are provided on the side of the main spoon body 1 away from the handle 2. A limiting groove 10 is formed between the L-shaped limiting blocks 9 and the side of the main spoon body 1 away from the handle 2. A baffle 11 is detachably installed in the limiting groove 10. In this design, the baffle 11 can close the opening on the side of the main spoon body 1 away from the handle 2, so that the particles can only enter and exit from the top opening during the retrieval process, reducing particle slippage and loss during retrieval. At the same time, during the transfer process after retrieval, it can completely prevent particles from falling from the side opening. The detachable design ensures that the baffle 11 will not obstruct the retrieval operation during the retrieval process, ensuring the smooth progress of the retrieval operation. After retrieval, the baffle 11 can be directly inserted vertically into the limiting groove 10. At the same time, the staff can hold the baffle 11 to prevent it from falling off during the transfer process.
