Description

Technical Field

[0001] This invention relates to a cutting fluid regeneration device, and more particularly to a cutting fluid regeneration device based on ion exchange. Background Technology

[0002] For cutting fluids, the main reason for controlling the chloride ion content is that chloride ions have a significant impact on the performance and service life of the cutting fluid.

[0003] First, chloride ions increase the corrosiveness and conductivity of cutting fluids, accelerating the corrosion and rusting of cutting components such as machine tools, fixtures, and cutting tools, thus shortening their service life. Furthermore, chloride ions promote the aging and deterioration of cutting fluids, accelerating problems such as acidification, bacterial growth, demulsification, and precipitation.

[0004] Secondly, chloride ions can also affect the health of workers.

[0005] Therefore, the chloride ion content must be strictly controlled in the formulation and use of cutting fluids to ensure the performance and service life of the cutting fluids, while also protecting the health and safety of workers.

[0006] Therefore, it is desirable to provide an intelligent device that reduces the chloride ion content in cutting fluid based on ion exchange, which can adsorb chloride ions in cutting fluid. Summary of the Invention

[0007] The purpose of this invention is to provide an intelligent device for reducing the chloride ion content of cutting fluid based on ion exchange. This device can adsorb chloride ions in the cutting fluid, thereby regenerating the cutting fluid. In addition, this intelligent device can also regenerate the ion exchange resin used to regenerate the cutting fluid, thereby significantly reducing costs.

[0008] To achieve the above objectives, this invention proposes an intelligent device for reducing the chloride ion content of cutting fluid based on ion exchange, comprising:

[0021] In the locked position, the locking rack is engaged with the gear, and the moving rack is not engaged with the gear.

[0022] When the moving rack and gear are engaged, the pressure rod of the moving rack presses the locking rack down vertically to the unlocking position, where the locking rack separates from the gear.

[0024] A fixing block is fixedly installed, and the fixing block is provided with a circular sliding groove;

[0025] The moving rack has an outwardly extending pin, which slides along the circular groove as the moving rack moves with the rotation of the cam around its central axis.

[0026] Furthermore, in the intelligent device for reducing the chloride ion content of cutting fluid based on ion exchange described in this invention, the conveyor belt drive device further includes:

[0048] The intelligent device for reducing chloride ion content in cutting fluid based on ion exchange according to the present invention will be further explained and described below with reference to the accompanying drawings and specific embodiments. However, this explanation and description do not constitute an undue limitation on the technical solution of the present invention.

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the intelligent device for reducing the chloride ion content of cutting fluid based on ion exchange according to the present invention includes:

[0050] Conveyor belt support 1 is fixedly installed on the ground, and several conveyor belt pulleys 2 are provided on the conveyor belt support 1. Figure 3 The diagram exemplarily shows seven conveyor belt pulleys, each capable of rotating about its own axis; a closed-loop conveyor belt 3, connected end-to-end, is conveyed by the rotation of the pulleys 2, the conveyor belt 3 containing ion exchange resin, and the surface of the conveyor belt 3 having numerous pores. A cutting fluid inlet pipe 4 is used to deliver cutting fluid to the conveyor belt 3, allowing the cutting fluid to enter the conveyor belt and be treated by the ion exchange resin therein; a cutting fluid reservoir 5 is located below the conveyor belt 3 corresponding to the cutting fluid inlet pipe 4, to receive and contain the cutting fluid flowing out of the cutting fluid inlet pipe 4 and through the ion exchange resin in the conveyor belt 3, and the cutting fluid reservoir 5 is equipped with a cutting fluid drain pipe 51.

[0051] Along the conveyor belt 3, the following are arranged in sequence: first cleaning water tank 6, acid washing tank 7, second cleaning water tank 8, alkaline washing tank 9 and third cleaning water tank 10.

[0052] The first cleaning water tank 6 is equipped with a first spray device 61, which is connected to external deionized water, so that the conveyor belt located in the first cleaning water tank 6 is cleaned with deionized water.

[0053] Furthermore, in some embodiments, a first compressed air pipe 62 can be connected to the first cleaning water tank 6. The first compressed air pipe 62 blows compressed air onto the conveyor belt 3 to backwash the ion exchange resin, loosen the ion exchange resin, remove small particles from the surface of the ion exchange resin, and rinse away excess water. In some more specific embodiments, two first compressed air pipes 62 can be arranged in the height direction of the first cleaning water tank 6 to cover a larger area of ​​the conveyor belt.

[0054] After passing through the first cleaning water tank 6, conveyor belt 3 enters the pickling tank 7, which contains acidic regeneration solution. For example... Figure 1 and Figure 4 As shown, the pickling tank has a pickling solution inlet pipe 71 and a pickling solution outlet pipe 72.

[0055] Then, the conveyor belt 3 enters the second cleaning water tank 8, which is equipped with a water inlet 82. Figure 4 As shown, the second cleaning water tank 8 is equipped with two water spray pipes 81, which are respectively located on both sides of the conveyor belt with the nozzles facing inward, for spraying deionized water onto the conveyor belt.

[0056] In some implementations, such as Figure 1 As shown, the water inlet 82 can be directly installed on the axle 22 of the conveyor belt pulley at this location.

[0057] like Figure 3 As shown, in some embodiments, the second cleaning water tank 8 is also provided with a pair of water scraping elements 83, which are respectively located above and below the conveyor belt. When the conveyor belt is conveyed, the water scraping elements 83 located against the conveyor belt can scrape off the water on the surface of the conveyor belt.

[0058] Then, conveyor belt 3 enters the alkaline washing tank 9 containing alkaline regeneration solution, such as... Figure 1 and Figure 4 As shown, the alkaline washing tank 9 has an alkaline washing liquid inlet pipe 91 and an alkaline washing liquid outlet pipe 92.

[0059] Finally, the conveyor belt 3 enters the third cleaning water tank 10. The third cleaning water tank 10 is equipped with a second spray device 101, which is connected to external deionized water, so that the conveyor belt located in the third cleaning water tank 10 is cleaned with deionized water. The bottom of the third cleaning water tank 10 is equipped with a drain outlet 103.

[0060] Furthermore, in some embodiments, a second compressed air pipe 102 can be connected to the third cleaning water tank 10. The second compressed air pipe 102 blows compressed air onto the conveyor belt 3 to backwash the ion exchange resin, loosening the ion exchange resin, removing small particles from the surface of the ion exchange resin, and rinsing away excess water. In some more specific embodiments, two second compressed air pipes 102 can be arranged in the height direction of the third cleaning water tank 10 to cover a larger area of ​​the conveyor belt.

[0061] In some implementations, such as Figure 1 As shown, a neutralization tank 11 can also be installed, which is connected to the pickling tank 7 via the pickling solution drain pipe 72 and to the alkaline washing tank 9 via the alkaline washing solution drain pipe 92. When the acidic and alkaline regenerated solutions become ineffective, the ineffective waste liquid can enter the neutralization tank 11 for environmental protection treatment before being discharged through the discharge port 111.

[0062] The conveyor belt drive device is connected to the active conveyor belt pulley 21 to drive the active conveyor belt pulley 21 to rotate intermittently, thereby causing other conveyor belt pulleys to rotate intermittently as well, so that the conveyor belt also moves intermittently.

[0063] Figure 5 This invention illustrates a conveyor belt drive device in one embodiment of the intelligent device for reducing chloride ion content in cutting fluid based on ion exchange.

[0064] like Figure 5 As shown, in some embodiments, the conveyor belt drive device may include: a drive device bracket 12, a cam 13 rotatably mounted on the drive device bracket 12 via a central pivot 131, and a cam drive element (not shown), such as a motor, driving the cam 13 to rotate around its central pivot 131. A moving rack 14 is connected to the cam 13 via a rack pivot 141, which is eccentrically positioned relative to the cam's central pivot 131, causing the moving rack 14 to move as the cam 13 rotates around its central pivot 131. The moving rack 14 is also provided with a pressure rod 142. A gear 15 is coaxially mounted with the drive conveyor belt pulley 21 via a gear shaft 151, and the moving rack 14 and locking rack 16 are respectively located on both sides of the gear 15. A base 18 is fixedly mounted on the drive device bracket 12 and is located below the locking rack 16. The base 18 has a column 181, and a compression spring 19 is sleeved on the column. Its two ends abut against the base 18 and the lower end face of the locking rack 16, respectively. The compression spring 19 provides elastic force to the locking rack 16 so that the locking rack 16 can move up and down in the height direction.

[0065] Furthermore, in some implementations, such as Figure 5 As shown, the conveyor belt drive device may also include a fixed block fixed on the drive device bracket 12, and the fixed block is provided with a circular groove 17; at the same time, the moving rack 14 has an outwardly protruding pin 143. The circular groove 17 and the pin 143 that cooperate with each other can provide guiding force for the moving rack 14 to further ensure the stability of the moving rack 14 during movement. When the moving rack 14 moves with the rotation of the cam 13 around its central axis, the pin 143 slides along the circular groove 17.

[0066] When the cam 13 rotates to its lowest point, the gear 15 meshes with the moving rack 14. The gear 15 rotates as the moving rack 14 moves horizontally, thereby driving the drive conveyor belt pulley 21 to rotate synchronously, thus enabling the conveyor belt 3 to move. In this state, the pressure rod 142 of the moving rack 14 presses the locking rack 16 down vertically to the unlocked position. In the unlocked position, the locking rack 16 is disengaged from the gear 15 and does not mesh.

[0067] As the cam 13 continues to rotate, it drives the moving rack to rise during the movement. The compression spring 19 gradually resets, causing the locking rack 16 to rise gradually. When the cam 13 rotates and drives the moving rack 14 to disengage from the gear 15, the locking rack 16 meshes with the gear 15, and the gear 15 stops rotating, thereby stopping the conveyor belt from moving. This achieves intermittent conveying.
