Description

Technical Field

[0001] This utility model relates to the technical field of wire rod processing equipment, and more specifically, to a solid-liquid separation device for the phosphating process in wire rod processing. Background Technology

[0002] Phosphating is a commonly used surface treatment technology with wide applications in industries such as automobiles, chemicals, shipbuilding, aerospace, and home appliances. During the phosphating process, phosphating slag precipitates are continuously generated along with the phosphating film-forming reaction. Phosphating slag is a pollutant, but the liquid contained in the phosphating slag can be recycled. In order to reduce the cost of phosphating, it is necessary to recycle the liquid in the phosphating slag.

[0003] In existing technologies, filter presses are generally used for solid-liquid separation of phosphate slag. By introducing the phosphate slag and liquid into a plate and frame filter and increasing the pressure, the filter cloth can intercept the phosphate slag and discharge the liquid, thus separating the phosphate slag and liquid. However, there are some problems in its use. During filtration, the phosphate slag will clog the filter cloth, requiring frequent cleaning. Furthermore, when the phosphate slag clogs the filter cloth, it will also affect the discharge of the liquid, thereby affecting the separation efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a solid-liquid separation device for the phosphating process in wire rod processing.

[0005] The technical solution of this utility model to achieve the above objectives is a solid-liquid separation device for the phosphating process of wire rod processing, including a support frame, a circular opening on the support frame, a centrifugal mechanism installed on the support frame, and a discharge mechanism installed on the support frame.

[0006] The centrifugation mechanism includes a centrifuge cylinder mounted on the upper end of a support frame, a stirring cylinder installed inside the centrifuge cylinder, a drive frame mounted on the support frame, and the drive frame can drive the centrifuge cylinder and the stirring cylinder to rotate. The stirring cylinder and the centrifuge cylinder can rotate relative to each other or remain relatively stationary. A liquid storage cylinder is installed on the outside of the centrifuge cylinder, and a drain pipe is installed on one side of the lower end of the liquid storage cylinder.

[0007] The discharge mechanism includes multiple discharge ports located at the lower end of the centrifuge cylinder, each discharge port is equipped with a protective door, and a collection box is placed below the support frame, the collection box being located below the discharge ports.

[0008] Furthermore, a one-way bearing is installed at the lower end of the centrifuge cylinder, and the one-way bearing is installed at the upper end of the support frame. The centrifuge cylinder has multiple filter holes. The stirring cylinder includes a circular rod located inside the centrifuge cylinder. The circular rod and the centrifuge cylinder are concentrically corresponding. The upper and lower ends of the circular rod are equipped with first rolling bearings, and the first rolling bearings are connected to the centrifuge cylinder through connecting rods.

[0009] Furthermore, the drive frame includes a support platform mounted on the upper end of the support frame, a servo motor mounted on the upper end of the support platform, a first sprocket mounted on the rotating end of the servo motor, a second sprocket mounted on the upper end of the round rod, the first sprocket and the second sprocket being connected by a transmission chain, a spring telescopic rod mounted on the upper end of the round rod, a pulley mounted on the telescopic end of the spring telescopic rod, an inclined platform mounted inside the centrifuge cylinder, and multiple scrapers mounted on the round rod.

[0010] Furthermore, the centrifuge drum has multiple square openings at its lower end, and the protective door includes a movable plate located at the square opening.

[0011] Furthermore, the upper end of the support frame has an annular groove, the lower end of the drain pipe extends into the annular groove, and a fixing pipe is installed on one side of the lower end of the annular groove.

[0012] The beneficial effects of this utility model are as follows: After simple filtration, the phosphate residue is placed into a centrifuge. By rotating the centrifuge, the liquid can be discharged into the storage tank and then discharged through the drain pipe. When the phosphate residue is blocked inside the centrifuge, the rotation of the stirring tank can scrape the phosphate residue from the inside of the centrifuge and stir it, thereby improving the separation efficiency. After the solid-liquid separation is completed, the protective door can be opened to facilitate the collection of the phosphate residue.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] This utility model provides, for example Figure 1-4The solid-liquid separation device shown is used in the phosphating process of wire rod processing. It includes a support frame 1 with a circular opening 2, a centrifugal mechanism and a discharge mechanism mounted on the support frame 1. The centrifugal mechanism includes a centrifugal cylinder 3 mounted on the upper end of the support frame 1, a stirring cylinder 4 installed inside the centrifugal cylinder 3, a drive frame 5 mounted on the support frame 1, and the drive frame 5 can drive the centrifugal cylinder 3 and the stirring cylinder 4 to rotate. The stirring cylinder 4 and the centrifugal cylinder 3 can rotate relative to each other or remain relatively stationary. A liquid storage cylinder 6 is installed on the outside of the centrifugal cylinder 3, and a drain pipe 7 is installed on one side of the lower end of the liquid storage cylinder 6. The discharge mechanism includes multiple discharge ports 8 located at the lower end of the centrifugal cylinder 3, a protective door 9 is installed at each discharge port 8, and a collection box 10 is placed below the support frame 1, located below the discharge ports 8.

[0022] The process of solid-liquid separation of phosphate slag in this device is as follows: The protective door 9 is closed, and the pre-filtered phosphate slag is placed into the centrifuge drum 3. The protective door 9 prevents the phosphate slag from falling through the discharge port 8. The drive frame 5 drives the stirring drum 4 and the centrifuge drum 3 to rotate synchronously, causing the phosphate slag inside the centrifuge drum 3 to rotate under centrifugal force. This causes the solid to be intercepted by the centrifuge drum 3, while the liquid enters the storage tank 6 through the centrifuge drum 3. Finally, the liquid is discharged through the drain pipe 7. After a period of time, the drive frame 5 drives the stirring drum 4 to reverse direction, and... This causes the centrifuge drum 3 to rotate, and the stirring drum 4 can stir the phosphate residue inside the centrifuge drum 3 and scrape the phosphate residue off the inner wall of the centrifuge drum 3. Then, the driving frame 5 can drive the stirring drum 4 and the centrifuge drum 3 to rotate synchronously and perform solid-liquid separation of the phosphate residue. After repeating this process several times, the protective door 9 is opened, and the phosphate residue can enter the collection box 10 through the discharge port 8 and the circular opening 2 under the action of gravity. The rotation of the centrifuge drum 3 can also accelerate the discharge. After the discharge is completed, the protective door 9 is closed, and new phosphate residue is added for solid-liquid separation.

[0023] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 A one-way bearing 11 is installed at the lower end of the centrifuge cylinder 3. The one-way bearing 11 is installed at the upper end of the support frame 1. Multiple filter holes 12 are opened on the centrifuge cylinder 3. The stirring cylinder 4 includes a round rod 13 located inside the centrifuge cylinder 3. The round rod 13 and the centrifuge cylinder 3 are concentrically corresponding. The upper and lower ends of the round rod 13 are equipped with first rolling bearings 14. The first rolling bearings 14 are connected to the centrifuge cylinder 3 through connecting rods 15. The one-way bearings 11 can prevent the centrifuge cylinder 3 from reversing. The filter holes 12 can intercept the phosphating slag when the centrifuge cylinder 3 rotates and allow the liquid to enter the storage cylinder 6. The round rod 13 is installed inside the centrifuge cylinder 3 through the first rolling bearings 14 and connecting rods 15, so it will not drive the centrifuge cylinder 3 to rotate, which facilitates the relative rotation of the stirring cylinder 4 and the centrifuge cylinder 3.

[0024] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2Included with instruction manual Figure 4 The drive frame 5 includes a support platform 16 mounted on the upper end of the support frame 1. A servo motor 17 is mounted on the upper end of the support platform 16. A first sprocket 18 is mounted on the rotating end of the servo motor 17. A second sprocket 19 is mounted on the upper end of the round rod 13. The first sprocket 18 and the second sprocket 19 are connected by a transmission chain 20. A spring telescopic rod 21 is mounted on the upper end of the round rod 13. A pulley 22 is mounted on the telescopic end of the spring telescopic rod 21. An inclined platform 23 is mounted inside the centrifuge cylinder 3. Multiple scrapers 24 are mounted on the round rod 13.

[0025] The process by which the drive frame 5 drives the stirring drum 4 and the centrifuge drum 3 to rotate is as follows: The servo motor 17 is started rotating forward, which drives the first sprocket 18 to rotate. The first sprocket 18 and the second sprocket 19 are connected by a transmission chain 20, which in turn drives the second sprocket 19 and the round rod 13 to rotate. The round rod 13 drives the spring telescopic rod 21 to rotate. When the spring telescopic rod 21 rotates to the position directly facing the inclined platform 23, the inclined platform 23 and the centrifuge drum 3 can rotate, thus allowing the stirring drum 4 and the centrifuge drum 3 to rotate synchronously, facilitating solid-liquid separation of the phosphate slag. The servo motor 17 is then started rotating forward. When the machine 17 reverses, the servo motor 17 can drive the first sprocket 18 to rotate. The first sprocket 18 and the second sprocket 19 are connected by the transmission chain 20, which in turn can drive the second sprocket 19 and the round rod 13 to rotate. The round rod 13 can drive the spring telescopic rod 21 to rotate. When the spring telescopic rod 21 rotates to the inclined surface position of the inclined platform 23, the spring telescopic rod 21 can be shortened and avoid the inclined platform 23. The one-way bearing 11 can prevent the centrifuge cylinder 3 from rotating, which can make the stirring cylinder 4 and the centrifuge cylinder 3 rotate relative to each other. Then the scraper 24 can scrape the inner wall of the centrifuge cylinder 3.

[0026] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 3 The centrifuge drum 3 has multiple square openings 25 at its lower end. The protective door 9 includes a movable plate 26 located at the square opening 25. The movable plate 26 is located above the discharge port 8 and is installed on the centrifuge drum 3 by bolts. A sealing gasket 27 is installed at the square opening 25. Under normal conditions, the movable plate 26 is connected to the centrifuge drum 3 by bolts. The movable plate 26 can block the discharge port 8, thereby preventing the phosphate residue from falling. The sealing gasket 27 can prevent liquid from leaking out from the square opening 25. When discharge is required, the operator pulls the movable plate 26 to one side, thereby allowing the discharge port 8 to leak out, which facilitates the phosphate residue falling into the collection box 10.

[0027] Refer to the instruction manual appendix Figure 1The upper end of the support frame 1 has a circular groove 28, and the lower end of the drain pipe 7 extends into the circular groove 28. A fixed pipe 29 is installed on one side of the lower end of the circular groove 28. When the liquid storage cylinder 6 drives the drain pipe 7 to rotate, the lower end of the drain pipe 7 can always be located in the circular groove 28, so that the liquid can be collected in the circular groove 28 and finally discharged through the fixed pipe 29 for recycling.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
