Description

Technical Field

[0001] This disclosure relates to the technical field of fastener production equipment, and particularly to a grease cleaning device after fastener processing. Background Technology

[0002] Fasteners are mechanical parts used to connect and fasten mechanical parts or structural components. During the production and molding process, oil from the machine can stick to the surface of the fastener. Fasteners with oil cannot be coated with chromium-free zinc-aluminum coating because there is a layer of oil between the fastener substrate and the coating liquid, and the coating liquid cannot adhere to the product surface.

[0003] Chinese utility model document CN215965201U discloses a modular ultrasonic cleaning device, including a shell, a cleaning tank inside the shell, an ultrasonic vibration unit inside the cleaning tank, a heating unit on one side of the cleaning tank, a circulating filter unit on the other side of the cleaning tank, and an auxiliary heating circulation unit on one side of the circulating filter unit. Existing technology can efficiently clean industrial products, achieving energy-saving circulation during the cleaning process. Furthermore, the components are easy to disassemble and maintain, resulting in low operating costs. However, different cleaning solutions have different optimal degreasing temperatures. For example, the optimal temperature for alkaline cleaning solutions to remove oil stains is generally around 60-80℃, while the optimal temperature for acidic cleaning solutions is typically 40-60℃. While existing technology can heat the cleaning solution during cleaning, it cannot control the heating temperature according to the temperature requirements of different cleaning solutions, nor can it maintain the optimal temperature of the cleaning solution throughout the cleaning process. Utility Model Content

[0004] The technical problem to be solved by this disclosure is that the cleaning fluid cannot be kept within the most suitable temperature range when cleaning the grease adhering to the fastener after processing.

[0005] To solve the above-mentioned technical problems, this disclosure provides a fastener grease cleaning device, including a housing with a corresponding bottom shell at the bottom. A cleaning tank is provided inside the housing. The device is characterized in that: a space is left between the cleaning tank and the housing; an ultrasonic generator is also provided on the outer wall of the cleaning tank; an electromagnetic heater is provided on the outer bottom of the cleaning tank; multiple temperature sensors are vertically and evenly arranged on the inner wall of the cleaning tank; a temperature controller is signal-connected to the temperature sensors and the heating device; and a display screen for operation is fixedly installed on the front of the housing and connected to the temperature controller via a wired interface.

[0006] Furthermore, elastic damping blocks are fixedly connected around the bottom of the cleaning tank, and protrusions corresponding to the elastic damping blocks are fixedly connected to the bottom shell. The protrusions have grooves in the middle with the same cross-sectional size and shape as the elastic damping blocks, and the depth of the grooves is less than the thickness of the elastic damping blocks.

[0007] Furthermore, the electromagnetic heater includes a concentric stepped electromagnetic coil centrally disposed on the bottom shell and a composite heating plate fixedly connected to the bottom of the cleaning tank at a position opposite to the concentric stepped electromagnetic coil.

[0008] Furthermore, ventilation openings are provided on the side wall of the outer casing, and cooling fans are installed in the ventilation openings.

[0009] Furthermore, a power supply is fixedly installed at the bottom back of the outer casing to power the entire cleaning device.

[0010] Furthermore, a cover plate is provided at the top of the space between the cleaning tank and the outer shell, and elastic shock-absorbing pads are provided at the connection between the cover plate and the cleaning tank and the outer shell.

[0011] Furthermore, a drain outlet is provided at the bottom of the cleaning tank, located at the bottom edge and offset from the heating system. The bottom shell has a channel corresponding to the drain outlet of the cleaning tank, and a support is provided at the bottom of the bottom shell. The drain pipe is fixedly connected to the drain outlet of the cleaning tank perpendicularly. After passing through the corresponding channel of the bottom shell, the drain pipe turns horizontal, and a drain valve is provided at the other end of the drain pipe.

[0012] This disclosure has the following beneficial effects:

[0013] Since the heating temperature range of the cleaning fluid is preset by inputting the control panel on the display, the controller controls the output power of the electromagnetic heater according to the set temperature range and the signal feedback from the sensor to achieve heating and heat preservation functions, so that the cleaning fluid is within the preset temperature range, ensuring that the cleaning fluid is at the most suitable degreasing temperature, improving cleaning efficiency while reducing energy consumption.

[0023] During the production of fasteners, grease may adhere to their surfaces. Before applying coatings, the grease on the fastener surface needs to be cleaned. High-temperature heating cleaning devices can cause the cleaning fluid to become ineffective or cause foam overflow if the temperature is too high, while low temperatures will result in poor cleaning performance. Different cleaning fluids require different temperature ranges for optimal cleaning results. Therefore, one aspect of this disclosure provides a fastener grease cleaning device with temperature control.

[0024] Please see Figures 1-6 As shown, this disclosure discloses a grease cleaning device for fasteners after processing. The cleaning device includes a housing 1, with a corresponding bottom shell 4 at the bottom. Preferably, the bottom shell 4 is connected to the housing 1 by screws. A cleaning tank 2 is disposed inside the housing 1, with a space between the cleaning tank 2 and the housing 1. A cover plate 3 is provided at the top of the space to seal it. Elastic shock-absorbing pads 9 are provided at the connection between the cover plate 3 and the cleaning tank 2 and the housing 1. An ultrasonic generator 55 is also provided on the outer wall of the cleaning tank 2. An electromagnetic heater is provided on the outer bottom of the cleaning tank 2. Multiple temperature sensors 54 are vertically and evenly arranged on the inner wall of the cleaning tank 2. During use, cleaning fluid is injected into the cleaning tank 2, partially or completely submerging the temperature sensors 54. The temperature sensors 54 are configured to detect the temperature of the cleaning fluid. A temperature controller 51 is signal-connected to the temperature sensors 54 and the heating device. The temperature controller 51 is configured to switch the output power of the heating device according to the temperature of the cleaning fluid.

[0025] Specifically, elastic damping blocks 21 are fixedly connected to the bottom of the cleaning tank 2 around its perimeter, and protrusions 43 corresponding to the elastic damping blocks 21 are fixedly connected to the bottom shell 4. The protrusions 43 have grooves 42 in the middle that are the same size and shape as the cross-section of the elastic damping blocks 21. The depth of the grooves 42 is less than the thickness of the elastic damping blocks 21. Through the interaction between the grooves 42 and the elastic damping blocks 21, the cleaning tank 2 can be supported and structural damage and noise caused by resonance of the outer shell 1 can be avoided.

[0026] Specifically, a support 41 is fixedly connected to the bottom of the base shell to support the cleaning equipment and provide installation space for the sewage system.

[0027] Specifically, the electromagnetic heater, located in the middle of the bottom shell 4, includes a concentric stepped electromagnetic coil 53 and a composite heating plate 52. The inner coil of the concentric stepped electromagnetic coil 53 has a turn spacing of 2-3 mm, and the outer coil has a turn spacing of 4-5 mm. The cross-sectional area of ​​the inner coil conductor is 15%-20% larger than that of the outer coil. The concentric stepped electromagnetic coil, through its stepped structure design of dense inner winding and sparse outer winding, improves the uniformity of the magnetic field distribution and energy conversion efficiency, resulting in uniform heating and reduced energy consumption. The composite heating plate 52 adopts a composite structure. The substrate of the composite heating plate 52 is a silicon steel sheet, and the surface is covered with a layer of 316L stainless steel through a plasma spraying process. The silicon steel sheet has high magnetic permeability, which can efficiently generate eddy currents during electromagnetic induction, achieving rapid heating. Furthermore, its low iron loss characteristics reduce energy consumption. The composite heating plate 52 possesses excellent mechanical properties, capable of withstanding thermal and mechanical stresses, ensuring structural stability. The 316L stainless steel layer on its surface resists corrosion from various chemicals, protecting the silicon steel substrate. This 316L stainless steel layer exhibits excellent high-temperature resistance, maintaining stable mechanical and chemical properties even at high temperatures. Its smooth surface reduces contact thermal resistance with the heated object, improving heat transfer efficiency and facilitating cleaning and maintenance. It also possesses good oxidation resistance. This composite heating plate allows the silicon steel substrate and the 316L stainless steel layer to work synergistically, combining efficient electromagnetic induction heating performance with the ability to operate stably in harsh environments for extended periods, while simultaneously reducing costs while maintaining performance.

[0028] Specifically, a vent is provided on the side wall of the housing, and a cooling fan 6 is provided in the vent. The cooling fan 6 blows air directly onto the electromagnetic heater to reduce its temperature.

[0029] Specifically, the temperature sensor 54 converts the temperature signal into an analog electrical signal. After processing by the analog-to-digital converter module built into the controller 51, the controller 51 generates a control signal based on the difference between the set temperature and the sensor feedback. This control signal is then sent to the drive circuit via the output terminal. The drive circuit adjusts the power output according to the output signal from the controller 51 and converts the control signal into a power form suitable for the heating device, such as adjusting the voltage / current through a driver to achieve precise power control. The output power of the drive circuit matches the rated power of the heating device to avoid overload or undervoltage. The temperature control system forms a closed loop through the real-time feedback from the temperature sensor 54, and the controller 51 dynamically adjusts the output signal according to a proportional algorithm.

[0030] Specifically, a display screen 5 for operation is fixedly installed on the front of the outer casing 1. The display screen 5 serves as a human-machine interface and is connected to the temperature controller 51 via a wired interface. Parameters such as target temperature and cleaning time can be set on the display screen 5. The display screen 5 can display the actual temperature inside the cleaning chamber 2, the working status of the heating device (on, off, current power), and the operating status of the ultrasonic generator 55 in real time. By setting parameters on the display screen 5, the temperature controller 51 can be controlled. The temperature controller 51 adjusts the output power of the drive circuit according to the set parameters to precisely control the heating device, thereby achieving effective control of the temperature of the cleaning chamber 2.

[0031] Specifically, a power supply 8 is fixedly installed at the bottom back of the outer casing 1 to supply power to the entire cleaning device.

[0032] The cleaning tank 2 has a drain outlet 72 at the bottom, which is located at the bottom edge and offset from the heating system. The bottom shell 4 has a channel 44 corresponding to the drain outlet 72 of the cleaning tank 2. The drain pipe 71 is vertically and fixedly connected to the drain outlet 72 of the cleaning tank 2. After passing through the corresponding channel 44 of the bottom shell 4, the drain pipe 71 turns to a horizontal position. The other end of the drain pipe 71 is equipped with a drain valve 7, forming a waste cleaning liquid discharge system.

[0033] A specific application of the operation process in this embodiment is as follows: When in use, the fasteners are placed into the hollow basket of the cleaning tank 2. The basket loading is controlled to be below 70% of the volume to avoid ultrasonic attenuation. Cleaning fluid is added to the cleaning tank 2. The liquid level must completely cover the temperature sensor 54 probe. Preferably, the liquid level is more than 2cm above the sensor. The operation is carried out through the touch screen on the front of the outer shell 1: Select the cleaning agent type. For example, if "acidic cleaning agent" is selected, the temperature is automatically set to 45±2℃; if "alkaline cleaning agent" is selected, the temperature is set to 60±5℃ or the target temperature is manually entered, such as the temperature range: 60-80℃, ±5℃. The ultrasonic cleaning time is set by default to 15 minutes, but can also be adjusted to a range of 5-60 minutes. The machine automatically shuts down when the temperature exceeds the set value. Press the start button. The equipment executes the following sequence: heating pre-start → activating ultrasonic waves when the temperature reaches 80% of the set value → entering the constant temperature cleaning stage. After cleaning is completed, the machine automatically enters the cooling stage. The cooling fan 6 continues to work until the temperature is <40℃. A buzzer sounds. Remove the basket.
