Description

Technical Field

[0001] This invention belongs to the technical field of sterilization equipment for rolling fluids, and specifically relates to an electromagnetic sterilization system for water-soluble rolling fluids. Background Technology

[0002] Rolling slurry is used as a coolant in metal processing. During its recycling, it is prone to bacterial growth. Since the rolling slurry circulation system often uses filters such as screens and precision filters, bacterial proliferation in these devices can cause blockages. While replacing these filters may provide short-term relief, the bacteria will eventually re-enter these devices at lower flow rates, causing further blockages, especially in components that are difficult to replace. This process will consume a significant amount of manpower and resources for cleaning and unclogging. According to statistics from our factory's rolling fluid circulation system, currently, to inhibit the rapid growth of bacteria in the rolling fluid, technicians maintain the temperature of the rolling fluid at 55-60 degrees Celsius, consuming a large amount of heat energy. Furthermore, multiple metal processing production lines operate 24 hours a day, requiring multiple personnel to conduct continuous inspections and then guide the on-site addition of rust inhibitors and corrosion inhibitors, consuming manpower and resources. In addition, the rolling oil needs to be changed 2-4 times a year, with each change wasting two days. Therefore, if high-frequency electromagnetic sterilization can be used for continuous sterilization, continuous manual inspection will be unnecessary, reducing the generation and discharge of waste liquid from the rolling fluid.

[0003] Currently, although there are electromagnetic sterilization devices on the market, they are not suitable for the circulating sterilization of rolling fluid. Furthermore, these electromagnetic sterilization devices are large, independent pieces of equipment that require a lot of space and are difficult to utilize by simply modifying existing production lines. Therefore, it is necessary to design a high-efficiency electromagnetic sterilization system that is easy to install and suitable for existing rolling fluid circulation systems. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, this solution provides an electromagnetic sterilization system for water-soluble rolling fluid.

[0005] The technical solution adopted in this invention is as follows:

[0006] An electromagnetic sterilization system for water-soluble rolling liquid includes an outer tube, an inner sterilization component, and a magnetic flux generating component;

The two ends of the central support mesh cylinder are connected to the first end disk and the second end disk, respectively. One end of the central support mesh cylinder is connected to the liquid inlet end of the outer tube, and the other end of the central support mesh cylinder is sealed. Several connecting mesh holes are provided on the tube wall of the central support mesh cylinder, and different mesh holes are connected to the corresponding separation channels. The central support mesh cylinder is made of an insulating and non-magnetic material.

[0013] As an alternative structure or supplementary design for the above-mentioned electromagnetic sterilization system for water-soluble rolling fluid: a number of metal protrusions are provided on the surface of the intermediate magnetic ring disk, the metal protrusions facing the partition channel, and can perform tip discharge on the rolling fluid in the partition channel when the intermediate magnetic ring disk generates an induced voltage.

[0014] As an alternative structure or supplementary design for the above-mentioned electromagnetic sterilization system for water-soluble rolling liquid: the intermediate magnetic ring disk has a structure with metal protrusions on one side, or the intermediate magnetic ring disk has a structure with metal protrusions on both sides.

[0016] As an alternative structure or supplementary design for the aforementioned electromagnetic sterilization system for water-soluble rolling liquid: an outlet pipe is provided at one end of the central support mesh cylinder. The outlet pipe extends out of the second end disk and is connected to the end wall of one end of the outer tube cylinder. The outlet pipe is connected to the intermediate connecting pipe.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. In this solution, during use, the first end disk and the second end disk can be used alternately as the S pole and N pole. When the disinfection space between the two alternates and a pulsed magnetic field is generated, the cell membrane of bacteria and other microorganisms can undergo electromagnetic induction under the action of the pulsed magnetic field, and change the membrane pressure of the microorganisms, ultimately achieving the effect of destroying the cell membrane and realizing sterilization.

[0022] 2. In this solution, an intermediate magnetic ring disk is arranged within the disinfection space, which divides the disinfection space into several partition channels. These partition channels are used to adjust the flow direction of the rolling liquid, ensuring that the flow direction of the rolling liquid is perpendicular to the magnetic field direction. This avoids the impact of turbulence or disturbance on the electromagnetic sterilization effect. Furthermore, the intermediate magnetic ring disk itself, being made of a soft magnetic alloy material, possesses high magnetic permeability, effectively guiding and transmitting the magnetic flux direction of the magnetic field. This effectively reduces the actual gap distance between the first end disk and the second end, improving the sterilization effect.

[0023] 3. The intermediate magnetic ring in this scheme adopts a circular structure, and metal protrusions are set on the intermediate magnetic ring. Under the action of electromagnetic induction, the metal protrusions can generate local tip discharge, and the released voltage can also achieve the bactericidal effect on bacteria and other microorganisms in the separation channel.

[0024] 4. The sterilization system in this solution is a tubular structure, which is compact and can be installed in series on the existing rolling fluid circulation system. It has the advantages of convenient installation and small space occupation, and is more suitable for retrofitting and upgrading existing rolling fluid circulation systems.

Detailed Implementation

[0032] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0033] Example 1

[0034] like Figures 1 to 5 As shown, this embodiment designs a water-soluble rolling liquid electromagnetic sterilization system, including an outer tube 14, an inner disinfection component, and a magnetic flux generation component.

[0035] The outer tube 14 is cylindrical. Its inlet end is connected to a rolling fluid delivery pump 7 via an intermediate connecting pipe 5. The rolling fluid delivery pump 7 is connected to a rolling fluid source via an inlet pipe 6. The outlet end of the outer tube 14 is connected to an outlet pipe 1, through which sterilized rolling fluid is output. The sterilization of the rolling fluid is primarily completed within the outer tube 14. Because the outer tube 14 is cylindrical, it can be directly connected in series with existing rolling fluid circulation systems during installation, offering advantages such as convenient installation and minimal space occupation. This makes it suitable for upgrading existing rolling fluid circulation systems.

[0036] A single internal disinfection component can be installed inside the outer tube 14, such as... Figures 1 to 2 As shown, multiple internal disinfection components can also be arranged along the axial direction of the outer tube 14, such as... Figures 4 to 5 As shown.

[0037] Each internal sterilization assembly includes components such as a first end disk 16, a second end disk 17, one or more intermediate magnetic ring disks 9, a central support mesh cylinder 10, and an outlet pipe 12; the first end disk 16 and the second end disk 17 are arranged side by side, forming a sterilization space between them for the passage and sterilization of the rolling liquid; the sterilization space is connected to the inlet and outlet of the outer tube 14; the rolling liquid can flow in from the center of the second end disk 17 and flow out from the gap between the first end disk 16 and the outer tube 14.

[0038] A separation channel 18 is formed between the intermediate magnetic ring disk 9 and the first end disk 16 and the second end disk 17; when there are multiple intermediate magnetic ring disks 9, a separation channel 18 is also formed between adjacent intermediate magnetic ring disks 9; the intermediate magnetic ring disk 9 is made of soft magnetic alloy, so that the separation channel 18 and the intermediate magnetic ring disk 9 together form part of the magnetic flux channel; after the rolling liquid is introduced from the ring center of the intermediate magnetic ring disk 9, it reaches the gap between the outer periphery of the intermediate magnetic ring disk 9 and the outer tube 14 along the separation channel 18, and flows to the liquid outlet end of the outer tube 14.

[0039] The central support mesh cylinder 10 is coaxially connected to the center of the intermediate magnetic ring disk 9. All the intermediate magnetic ring disks 9 are connected to the same central support mesh cylinder 10. The two ends of the central support mesh cylinder 10 are connected to the first end disk 16 and the second end disk 17, respectively. One end of the central support mesh cylinder 10 is connected to the liquid inlet end of the outer tube 14, and the other end of the central support mesh cylinder 10 is sealed. Several connecting mesh holes 19 are provided on the tube wall of the central support mesh cylinder 10, with different mesh holes 19 connecting to corresponding partition channels 18. The central support mesh cylinder 10 is made of an insulating and non-magnetic material. When there are two internal disinfection components, such as... Figure 3 As shown, the two inner disinfection components are connected and communicated between their central support mesh cylinders 10 via an intermediate connecting cylinder 15.

[0040] The lead-out pipe 12 is located at one end of the central support mesh cylinder 10. The lead-out pipe 12 extends out of the second end disk 17 and is connected to the end wall of one end of the outer tube cylinder 14. The lead-out pipe 12 is connected to the intermediate connecting pipe 5.

[0041] A plurality of metal protrusions 13 are disposed on the surface of the intermediate magnetic ring disk 9. These metal protrusions 13 face the separating channel 18 and are capable of tip discharge of the rolling fluid in the separating channel 18 when an induced voltage is generated in the intermediate magnetic ring disk 9. The intermediate magnetic ring disk 9 may have a single-sided structure with metal protrusions 13, or it may have a double-sided structure with metal protrusions 13 (e.g., ...). Figure 3 (As shown). In addition, metal protrusions 13 are arranged on the side of the first end disk 16 facing the second end disk 17, or metal protrusions 13 are arranged on the side of the second end disk 17 facing the first end disk 16, or metal protrusions 13 are arranged on the sides of the first end disk 16 and the second end disk 17 that are close to each other.

[0042] Multiple magnetic flux generating components are connected to the outer side of each inner disinfection component. When four magnetic flux generating components are connected to the same inner disinfection component, the four magnetic flux generating components are arranged in a ring around the outer side of the outer wall of the outer tube 14, such as... Figure 1 and Figure 4 As shown.

[0043] The flux generating component is connected to the first end disk 16 and the second end disk 17, and uses the first end disk 16 and the second end disk 17 as magnetic poles to create a magnetic field in the disinfection space. The flux generating component includes a main magnetic core structure and a coil coil 3. The coil coil 3 is wound around the main magnetic core structure and electrically connected to an alternating power supply. One or more coil coils 3 are provided outside each main magnetic core structure. The coil coils 3 are electrically connected in series or parallel. The interior of each coil coil 3 is made of copper wire, and each coil coil 3 can be wrapped with an insulating layer to achieve insulation. The main magnetic core structure is C-shaped, and the two ends of the main magnetic core structure are magnetically connected to the first end disk 16 and the second end disk 17.

[0044] The main magnetic core structure includes an L-shaped connector 2, a lead-out post 8, and a magnetic core body 4. The lead-out post 8 is fixedly installed and penetrates the wall of the outer tube 14. The second end disk 17 and the first end disk 16 are both magnetically connected to the lead-out post 8. The magnetic core body 4 is columnar and used for the installation of the coil 3. Both ends of the magnetic core body 4 are connected to the corresponding lead-out post 8 magnetic core through an L-shaped connector 2. The L-shaped connector 2, the lead-out post 8, and the magnetic core body 4 are all detachably connected. Screw clips 11 can be fixedly installed at the external connection positions of the L-shaped connector 2, the lead-out post 8, and the magnetic core body 4, thereby achieving the connection between the three by connecting the screw clips 11. When the three are connected, the coil 3 will generate a magnetic field inside the magnetic core body 4 under the action of alternating current. The magnetic field can be transmitted to the first end disk 16 or the second end disk 17 through the L-shaped connector 2 and the lead-out post 8, thereby creating a magnetic field inside the outer tube 14.

[0045] In this embodiment, during use, the inlet pipe 6 draws in the rolling fluid and injects it into the intermediate connecting pipe 5 via the rolling fluid delivery pump 7. The intermediate connecting pipe 5 then delivers the rolling fluid into the outer tube 14, where it flows successively through the outlet pipe 12 and the central support mesh cylinder 10. The rolling fluid in the central support mesh cylinder 10 flows out through the mesh openings 19 and into the separating channel 18, then flows from the gap outside the intermediate magnetic ring disk 9 to the outlet end of the outer tube 14, and finally flows out through the outlet pipe 1. During this process, when the magnetic flux generating component generates a pulsed magnetic field, the disinfection space also generates a pulsed magnetic field to electromagnetically sterilize the rolling fluid in the disinfection space. The first end disk 16 and the second end disk 17 can be used alternately as the S and N poles. When the disinfection space between them alternates and generates a pulsed magnetic field, the cell membranes of bacteria and other microorganisms undergo electromagnetic induction under the influence of the pulsed magnetic field, changing the membrane pressure of the microorganisms and ultimately destroying the cell membrane, thus achieving sterilization. In addition to the magnetic conduction function of the central magnetic ring, the tip discharge generated by the central magnetic ring and the metal protrusion 13 under the action of electromagnetic induction can also be released into the separation channel 18, thereby further increasing the bactericidal effect of microorganisms.

[0046] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
