Description

Technical Field

[0001] This application relates to the field of non-ferrous metal rod polishing technology, and more particularly to a dust removal device for polishing non-ferrous metal rods. Background Technology

[0002] Non-ferrous metal bars are an important basic material in the industrial field, widely used in many industries due to their unique physical and chemical properties. Non-ferrous metal bars can be divided into various types, such as copper bars, aluminum bars, zinc bars, nickel bars, and titanium bars. Titanium bars, for example, are used in the medical field to manufacture various medical devices, such as surgical instruments and clamps, due to their excellent corrosion resistance, high strength-to-weight ratio, and biocompatibility. They are also ideal materials for making medical implants, such as prostheses, bone fixation screws, and dental implants. In the chemical industry, they are used in reaction vessels and heat exchangers. In the aerospace field, they are used in aircraft engine components; in marine engineering, in ship parts and subsea pipelines, etc. Therefore, non-ferrous metal bars are widely used in both industrial and daily life sectors.

[0003] The processing technology for non-ferrous metal bars is basically the same as that for other metal bars, including smelting and machining. However, in the later stages of machining, surface polishing is an essential machining step to improve the surface quality of the bars (for example, titanium bars used for implantation require high surface quality). Currently, the surface polishing of bars uses the method described in the attached manual. Figure 1 The polishing wheels are symmetrically arranged as shown. The rod to be polished is placed on the symmetrical polishing wheels, and the weight of the rod makes it adhere to the polishing wheels. The polishing wheels then rotate in the direction shown by the arrows in the diagram, driving the rod to move axially, thus achieving complete polishing of the rod both circumferentially and axially. To avoid increased heat on both the polishing wheels and the rod during polishing, which could cause the rod surface to blacken due to high temperature, as shown... Figure 1 As shown, the rod is cooled by a cooling pipe during the polishing process.

[0004] During the continuous polishing of the bar stock, the titanium dust generated during polishing mixes with the coolant and flows into the lower return tank. The mixture then flows through an outlet on one side of the return tank to a sedimentation tank (not shown in the figure). To avoid wasting coolant, the coolant that has settled and separated at the top of the sedimentation tank is usually returned for further cooling. However, due to insufficient sedimentation, the titanium dust, carried by the returning coolant, cools the surface of the bar stock. Under the contact action of the larger polishing wheel, the titanium dust adheres to the surface of the bar stock, affecting the polishing quality. Simultaneously, the bottom surface of the return tank has a relatively large dust and sludge distribution due to the flow of the mixture (e.g., ...). Figure 11 As shown in the image, it is difficult to clean.

[0005] And such Figure 4As shown, if a bottom filter screen is arranged on one side of the reflux tank, the dust sludge gradually accumulates on the filter screen, resulting in continuous increase of the accumulated dust sludge, and the through of the cooling liquid is affected, and the accumulated dust sludge on the filter screen needs to be cleaned frequently. SUMMARY

[0006] In view of the above problems, the present application aims to provide a polishing dust removal device for non-ferrous metal rods, which separates the polishing dust and the cooling liquid before flowing into the sedimentation tank and blocks the dust, realizes primary separation, reduces the dust entering the sedimentation tank with the cooling liquid, avoids the disadvantage that the sedimentation tank is filled with too much (high) dust which is brought out by the cooling liquid again, and improves the surface polishing quality of the rods.

[0007] In order to achieve the above-mentioned purpose, the technical scheme adopted by the present application is as follows: a polishing dust removal device for non-ferrous metal rods, the polishing operation of the rod includes a polishing wheel, a reflux tank for cooling liquid is arranged at the bottom of the polishing wheel, and a flow outlet is arranged on one side of the reflux tank, characterized in that: the polishing dust removal device is arranged in the reflux tank and located in front of the cooling liquid flowing to the flow outlet, and the polishing dust removal device can separate the polishing dust and the cooling liquid and block the dust.

[0008] Preferably, the polishing dust removal device is a separation plate arranged in the reflux tank and located at the position in front of the cooling liquid flowing to the flow outlet, and the separation plate is arranged obliquely in the reflux tank.

[0009] Preferably, a filter screen for separating the cooling liquid and the dust is arranged on the top of the separation plate at a certain angle and obliquely upward.

[0010] Preferably, the filter screen is hingedly connected to the top end of the separation plate and can be locked.

[0011] The polishing dust removal device can separate the polishing dust and the cooling liquid before flowing into the sedimentation tank and block the dust, that is, primary separation is realized before the sedimentation tank, and after the dust is blocked, the dust entering the sedimentation tank with the cooling liquid is reduced, the mixed liquid entering the sedimentation tank has a clear state (the mixed liquid contains less titanium dust) compared to the current state, the titanium dust in the mixed liquid can be precipitated and separated from the cooling liquid in a shorter time, and the disadvantage that the sedimentation tank is filled with too much (high) dust which is brought out by the cooling liquid again is avoided. In combination with the primary separation in the reflux tank, the cleanliness of the cooling liquid which is in contact with the rod again after reflux and precipitation is improved, and the surface polishing quality of the rod is improved. At the same time, after the cooling liquid and the dust are separated in the reflux tank, the dust can be quickly cleaned subsequently. BRIEF DESCRIPTION OF DRAWINGS

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present application, the technical solutions of the present application are further described below in combination with the accompanying drawings and examples.

[0025] Referring to the accompanying drawings, a polishing and dust removing device for non-ferrous metal bars is shown. Figures 1-10 The polishing operation of the bar includes a polishing wheel 1, a backflow tank 2 for cooling liquid provided at the bottom of the polishing wheel 1, and a flow outlet 2a provided at one side of the backflow tank 2. Figures 1-2 As shown, the cooling liquid and the polished titanium dust mixed liquid flow onto the inner bottom surface of the backflow tank 2, and then flow from the flow outlet 2a at one side of the backflow tank 2 to a sedimentation tank for a short time of sedimentation, and then the cooling liquid is used again for cooling in the bar polishing process. Figure 1 Figure 2

[0026] To address the issue of titanium dust adhering to the surface of the rods when the unprecipitated mixture is recirculated for cooling, this application includes a polishing dust removal device, such as... Figures 5-7 As shown, this polishing dust removal device is located within the return tank 2 and upstream of the coolant flow to the outlet 2a. It separates the polishing dust from the coolant and blocks the dust. Specifically, it separates the coolant from the dust in the mixture upstream of the outlet 2a, achieving primary separation. By blocking the dust, it reduces the amount of dust entering the sedimentation tank with the coolant. The mixture entering the sedimentation tank is now clearer (containing less titanium dust), allowing the titanium dust to settle and separate from the coolant in a shorter time. This avoids the drawback of a large amount of dust settling in the sedimentation tank being carried out again by the coolant. Combined with the primary separation in the return tank 2, this improves the cleanliness of the coolant that comes into contact with the rod again after return, thereby improving the surface polishing quality of the rod. Simultaneously, separating the coolant from the dust in the return tank 2 also facilitates rapid subsequent dust removal.

[0027] Specifically, such as Figures 5-7 As shown, the polishing dust removal device is a separation plate 3 installed in the return tank 2 and located in front of the coolant flow outlet 2a. The separation plate 3 is inclined within the return tank 2. The separation effect of the separation plate 3 on the mixture is as follows: the falling mixture forms a barrier upon contact with the separation plate 3, and as the mixture level rises, the coolant flows outwards... Figure 7 The mixture "jumps" from the top of the separation plate 3 in the direction indicated by the middle arrow, while the titanium dust is blocked by gravity and settles on the inner side of the separation plate 3, thus achieving primary separation of the mixture and improving the cleanliness of the mixture at the top of the "jumping" separation plate 3. The inclined separation plate 3, compared to a vertical structure, can mitigate the impact of the "jumping" of the mixture, preventing the dust and sludge blocked by the separation plate 3 from being carried out. When there is a large amount of dust and sludge settled on the inner side of the separation plate 3, the dust and sludge are cleaned. Since the separation plate 3 is located in front of the outlet 2a, the flow area of ​​the mixture is reduced, thus shrinking the accumulation area of ​​the dust and sludge, facilitating rapid cleaning and solving the problem that dust and sludge are currently distributed throughout the entire bottom surface of the return tank 2 and are difficult to clean effectively.

[0028] To further improve the separation effect of the mixture in reflux tank 2, such as Figures 8-9 As shown, a filter screen 4, angled upwards at the top of the separation plate 3, separates the coolant from the dust and sludge. This filter screen blocks and filters the dust and sludge carried by the mixture downwards, improving the cleanliness of the mixture and also increasing the sedimentation efficiency of the subsequent sedimentation tank. The filter screen 4 is positioned above the mixture, utilizing gravity to cause the dust and sludge to accumulate downwards (as shown by arrow b in the figure; arrow a indicates the coolant flow path), thus preventing contact with the filter screen 4 and avoiding...Figure 4 The dust and sludge accumulation will block the filter screen.

[0029] In order to clean the dust and sludge accumulated inside the separation plate 3, the filter screen 4 is hingedly connected at the top end of the separation plate 3, as shown. Figure 10 Preferably, the separation plate 3 is hingedly connected with the filter screen 4 by a hinge screw (not shown in the figure), so that during the cleaning of the dust and sludge, the filter screen 4 is flipped over, as shown. Figure 10

[0030] The principle of the present application is that a slanting separation plate 3 is arranged in the return tank of the cooling liquid and in front of the flow outlet 2a, and a filter screen 4 is hingedly connected at the top end of the separation plate 3. When the mixed liquid flowing down to the return tank 2 is blocked after contacting the inside of the separation plate 3 during the polishing process, the cooling liquid "flips" from the top end of the separation plate 3 as the liquid level of the mixed liquid rises, while the titanium dust is blocked and deposited on the inside of the separation plate 3 due to its gravity, thereby achieving the first separation of the mixed liquid, and improving the cleanliness of the mixed liquid "flipping" the top end of the separation plate 3. The mixed liquid after "flipping" flows through the flow outlet 2a to the sedimentation tank for sedimentation, and the cooling liquid on the top side of the sedimentation tank is again extracted by the pump body to the cooling pipe at the top of the polishing wheel and sprayed out. After a large amount of dust and sludge is accumulated inside the separation plate 3, the filter screen 4 is flipped over, and after flipping, the accumulated dust and sludge can be quickly removed and cleaned.

[0031] The basic principles, main features and advantages of the present application are shown and described above. There can be various changes and improvements to the present application without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the claimed present application.​
