Description

Technical Field

[0001] This application relates to the field of copper foil, and more particularly to a diatomaceous earth filter and filtration system. Background Technology

[0002] Currently, the filtration system for the copper melting process mainly consists of diatomaceous earth filters, bag filters, and cartridge filters. Diatomaceous earth filters play a crucial role in the copper melting process, primarily by adsorbing organic matter and intercepting large particulate impurities. However, in actual production, the thickness of the diatomaceous earth filter layer continuously increases over time. When the filter layer reaches a certain thickness, it is necessary to remove the diatomaceous earth and re-form the filter.

[0003] Traditional soil unloading methods mainly involve draining the system electrolyte into the sludge tank; drying the soil with compressed air supplied by an air compressor; and then blowing the soil off the filter cloth sleeve with compressed air supplied by the air compressor from the inside of the pipe. This unloading process takes a long time, and the high pressure of the compressed air during backflushing can easily damage the filter cloth sleeve, increasing the cost of the filter material and causing abnormal copper foil quality.

[0004] How to shorten the unloading time while minimizing damage to the filter cloth sleeve of diatomaceous earth filters has become an urgent problem to be solved in this field. Utility Model Content

[0005] This application discloses a diatomaceous earth filter and filtration system, with the aim of shortening the unloading time while minimizing damage to the filter cloth sleeve of the diatomaceous earth filter.

[0006] This application discloses a diatomaceous earth filter, which includes a housing, a vibrator, a lobed tube, and a filter cloth sleeve. The vibrator is disposed inside the housing, the lobed tube is connected below the vibrator, and the filter cloth sleeve is sleeved on the lobed tube. The filter cloth sleeve is coated with a diatomaceous earth layer. The housing has an opening corresponding to the bottom of the lobed tube. When the diatomaceous earth filter is in a first state, the vibrator vibrates and drives the lobed tube to vibrate.

[0007] Optionally, the vibrator includes an ultrasonic generator and an ultrasonic transducer. The ultrasonic generator is electrically connected to the ultrasonic transducer. The ultrasonic generator transmits an electrical signal to the ultrasonic transducer. The ultrasonic transducer vibrates based on the electrical signal to generate ultrasonic waves and drive the plum blossom tube to vibrate.

[0008] Optionally, there are multiple plum blossom tubes and multiple ultrasonic transducers, with each plum blossom tube connected to each ultrasonic transducer.

[0009] Optionally, the housing is provided with a fixing frame and a placement frame, the placement frame and the fixing frame are respectively connected to the housing, the fixing frame is located below the placement frame and connected to the bottom of the placement frame; a plurality of the plum blossom tubes are installed on the fixing frame, and the ultrasonic transducer is installed on the placement frame.

[0010] Optionally, the diatomaceous earth filter further includes a first sealing structure and a second sealing structure. The first sealing structure is disposed above and connected to the second sealing structure. The first sealing structure is used to encapsulate the ultrasonic generator, and the second sealing structure is used to encapsulate a plurality of ultrasonic transducers.

[0011] Optionally, a valve is provided on the opening, and the valve and the ultrasonic generator are electrically connected to an external power source. The external power source controls the valve and the ultrasonic generator to open or close simultaneously.

[0012] Optionally, the diatomaceous earth filter further includes a collection device connected to the opening.

[0013] Optionally, the housing is further provided with an outlet and an inlet, the outlet being located at the top of the housing and the inlet being located on the side wall of the housing near the opening; a first pressure sensor is provided on the outlet and a second pressure sensor is provided on the inlet.

[0014] This application also discloses a filtration system, including a control device, the filtration system further including the diatomaceous earth filter described above, and the control device being connected to the diatomaceous earth filter.

[0015] Optionally, the control device further includes a frequency controller, which is wirelessly connected to the first pressure sensor and the second pressure sensor respectively; the frequency controller adjusts the output frequency of the ultrasonic generator according to the pressure difference between the liquid inlet and the liquid outlet detected by the first pressure sensor and the second pressure sensor.

[0016] This application improves upon traditional diatomaceous earth filters by installing a vibrator inside the filter housing and connecting a perforated tube below the vibrator. When the diatomaceous earth filter is in its first state, the vibrator starts and generates vibration, which is transmitted to the perforated tube, causing the filter cloth sleeve fitted on the perforated tube to vibrate as well. As the filter cloth sleeve vibrates, the diatomaceous earth adhering to its surface is quickly shaken off. The shaken-off diatomaceous earth can fall smoothly through the opening at the bottom of the housing, thus quickly completing the unloading operation. Since the perforated tube vibration method drives the filter cloth sleeve vibration, the damage to the filter cloth sleeve is minimized, thereby shortening the unloading time while reducing damage to the filter cloth sleeve.

Detailed Implementation

[0027] The present application will now be described in detail with reference to the accompanying drawings and optional embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Figure 1 This is a schematic diagram of the first embodiment of the diatomaceous earth filter of this application. Figure 2 This is a schematic diagram of the housing in the first embodiment of the diatomaceous earth filter of this application, as shown. Figure 1 and Figure 2 As shown in the embodiment of this application, a diatomaceous earth filter 100 is disclosed. The diatomaceous earth filter 100 includes a housing 110, a vibrator 160, a quincunx tube 170, and a filter cloth sleeve 180. The vibrator 160 is disposed inside the housing 110, the quincunx tube 170 is connected below the vibrator 160, and the filter cloth sleeve 180 is sleeved on the quincunx tube 170. A diatomaceous earth layer 190 is coated on the filter cloth sleeve 180. The housing 110 is provided with an opening 111 at the bottom of the quincunx tube 170. When the diatomaceous earth filter 100 is in the first state, the vibrator 160 vibrates and drives the quincunx tube 170 to vibrate.

[0029] This application improves upon the traditional diatomaceous earth filter 100 by installing a vibrator 160 in the housing 110 of the diatomaceous earth filter 100 and connecting a quincunx tube 170 below the vibrator 160. When the diatomaceous earth filter 100 is in its first state, the vibrator 160 is activated and vibrates, which is transmitted to the quincunx tube 170, thereby causing the filter cloth sleeve 180 fitted on the quincunx tube 170 to vibrate as well. As the filter cloth sleeve 180 vibrates, the diatomaceous earth adhering to its surface is quickly shaken off. The shaken-off diatomaceous earth can fall smoothly through the opening 111 at the bottom of the housing 110, thus quickly completing the soil unloading operation. Since the vibration of the quincunx tube 170 drives the vibration of the filter cloth sleeve 180, the damage to the filter cloth sleeve 180 is minimized, thus shortening the soil unloading time while reducing damage to the filter cloth sleeve 180.

[0030] It should be noted that in the embodiments of this application, the first state of the diatomaceous earth filter 100 can be understood as the state in which the diatomaceous earth filter 100 should be unloaded; for example, when the pressure of the diatomaceous earth filter 100 reaches 0.35MPa or when the diatomaceous earth filter 100 runs out of filter material and needs to be refilled, the diatomaceous earth filter 100 is in the first state.

[0031] Specifically, the vibrator 160 includes an ultrasonic generator 161 and an ultrasonic transducer 162. The ultrasonic generator 161 is electrically connected to the ultrasonic transducer 162. The ultrasonic generator 161 transmits an electrical signal to the ultrasonic transducer 162. The ultrasonic transducer 162 vibrates based on the electrical signal and drives the plum blossom tube 170 to vibrate.

[0032] In this embodiment, the vibrator 160 mainly consists of an ultrasonic generator 161 and an ultrasonic transducer 162. When unloading operations are required, the ultrasonic generator 161 outputs an electrical signal of a specific frequency to the ultrasonic transducer 162. The ultrasonic transducer 162 converts electrical energy into mechanical energy, causing it to vibrate and generate ultrasonic waves. Since a perforated tube 170 is connected below the ultrasonic transducer 162, when the ultrasonic transducer 162 vibrates and generates ultrasonic waves, the ultrasonic waves are transmitted to the perforated tube, causing the perforated tube 170 to vibrate along with the ultrasonic transducer 162. This, in turn, causes the filter cloth sleeve 180, which is fitted onto the perforated tube 170, to achieve comprehensive and stable vibration. In this way, the diatomaceous earth coated in each area of ​​the filter cloth sleeve 180 can be shaken off, achieving rapid unloading operations. Furthermore, since the filter cloth sleeve 180 vibrates entirely using ultrasonic waves, it is less prone to damage, effectively extending the service life of the filter cloth sleeve 180.

[0033] Furthermore, there are multiple plum blossom tubes 170 and multiple ultrasonic transducers 162, with each plum blossom tube 170 connected to each ultrasonic transducer 162 respectively.

[0034] When the ultrasonic generator 161 emits electrical signals, these signals are precisely transmitted to the corresponding ultrasonic transducers 162. The ultrasonic waves generated by each ultrasonic transducer 162 can be independently transmitted to the corresponding perforated tubes 170, thereby enabling each perforated tube 170 to vibrate at the required frequency and amplitude. In this way, the diatomaceous earth attached to each perforated tube 170 can be smoothly detached under appropriate vibration, improving the efficiency and effectiveness of the unloading operation.

[0035] Furthermore, if a particular tube 170 or its corresponding ultrasonic transducer 162 malfunctions, it will not affect the normal operation of other tubes 170, facilitating equipment inspection and maintenance. During subsequent use, operators can address the problematic tube 170 specifically without worrying about significantly impacting the entire filter, thereby reducing equipment maintenance costs and downtime, and ensuring the stable operation of the diatomaceous earth filter 100.

[0036] Furthermore, a fixing frame 120 and a placement frame 130 are provided inside the housing 110. The placement frame 130 and the fixing frame 120 are respectively connected to the housing 110. The fixing frame 120 is located below the placement frame 130 and is connected to the bottom of the placement frame 130. Multiple plum blossom tubes 170 are installed on the fixing frame 120, and the ultrasonic transducer 162 is installed on the placement frame 130.

[0037] In this embodiment, by mounting the plum blossom tube 170 on the fixing frame 120 and the ultrasonic transducer 162 on the placement frame 130, the fixing frame 120 provides stable support for the plum blossom tube 170, ensuring that it will not shake or shift during operation and guaranteeing the normal operation of the filtration process. The placement frame 130 provides a suitable installation position for the ultrasonic transducer 162, allowing the transducer to be accurately connected to the plum blossom tube 170, making the installation of the plum blossom tube 170 and the ultrasonic transducer 162 more secure.

[0038] It also facilitates the coordinated operation between the ultrasonic transducer tube and the plum blossom tube 170. When the ultrasonic generator 161 transmits an electrical signal to the ultrasonic transducer 162, the ultrasonic transducer 162 can convert the electrical signal into mechanical vibration, thereby generating ultrasonic waves. The ultrasonic waves can be transmitted to the plum blossom tube 170 through the placement frame 130 and the fixing frame 120, so that the filter cloth sleeve 180 fitted on the plum blossom tube 170 can achieve efficient cleaning of diatomaceous earth by means of ultrasonic vibration.

[0039] Moreover, due to the connection between the fixing frame 120 and the placement frame 130 and the housing 110, when the ultrasonic transducer 162 and the plum blossom tube 170 vibrate, the fixing frame 120 and the placement frame 130 can effectively disperse the vibration and impact force generated during the operation of the equipment onto the housing 110, avoiding excessive local stress that could damage the equipment and extending the service life of the equipment.

[0040] In this embodiment, the ultrasonic generator 161 is connected to an external power supply 300, which powers the ultrasonic generator 161. When the diatomaceous earth filter 100 experiences filter leakage (the filter cloth cover 180 is damaged), the filter cloth cover 180 needs to be replaced. First, unplug the cable plug at the location of the ultrasonic generator 161, then remove the screws between the fixing bracket 120 and the placement bracket 130, remove the entire part above the fixing bracket 120, place it in a safe location, and reinstall it after all the filter cloth covers 180 have been replaced.

[0041] Figure 3 This is a schematic diagram of a second embodiment of the diatomaceous earth filter of this application, as shown below. Figure 3 As shown, the diatomaceous earth filter 100 also includes a first sealing structure 140 and a second sealing structure 150. The first sealing structure 140 is disposed above the second sealing structure 150 and connected to the second sealing structure 150. The first sealing structure 140 is used to encapsulate the ultrasonic generator 161, and the second sealing structure 150 is used to encapsulate a plurality of ultrasonic transducers 162.

[0042] The difference between this embodiment and the previous embodiment is that in this embodiment, the ultrasonic generator 161 and the ultrasonic transducer 162 are encapsulated using the first encapsulation structure and the second encapsulation structure, respectively, to prevent external dust, moisture and other impurities from entering the ultrasonic generator 161 and the ultrasonic transducer 162, thereby ensuring the normal operation of the ultrasonic generator 161 and the ultrasonic transducer 162.

[0043] The first sealing structure 140 encapsulates the ultrasonic generator 161, preventing it from malfunctioning due to external interference and ensuring stable transmission of electrical signals. The second sealing structure 150 encapsulates multiple ultrasonic transducers 162, ensuring that the transducers operate in a stable environment, effectively maintaining their vibration performance, and thus stably transmitting ultrasonic waves to the plum blossom tube, allowing the plum blossom tube 170 to vibrate continuously and stably with the aid of ultrasonic waves.

[0044] Meanwhile, the first sealing structure 140 is connected to the second sealing structure 150, further enhancing the integrity and stability of the entire sealing system.

[0045] Figure 4 This is a schematic diagram of the housing in the third embodiment of the diatomaceous earth filter of this application, as shown. Figure 4 As shown, the housing 110 is also provided with an outlet 115 and an inlet 113. The outlet 115 is located on the top of the housing 110, and the inlet 113 is located on the side wall of the housing 110 near the opening 111. A first pressure sensor 116 is provided on the outlet 115, and a second pressure sensor 114 is provided on the inlet 113.

[0046] In this embodiment, a first pressure sensor 116 and a second pressure sensor 114 are respectively installed at the liquid outlet 115 and liquid inlet 113 of the housing 110. The first pressure sensor 116 is used to monitor the pressure of the liquid at the liquid outlet 115 in real time and can accurately reflect the pressure value of the electrolyte flowing out of the housing 110. The second pressure sensor 114 is used to monitor the pressure of the liquid at the liquid inlet 113 in real time and can accurately reflect the pressure value of the electrolyte flowing into the housing 110. In this way, the operator can determine the thickness of the diatomaceous earth by analyzing the pressure value, and can also determine the filtration effect of the diatomaceous earth filter 100 and the smoothness of the electrolyte flow, and adjust the diatomaceous earth filter 100 or unload the soil in time.

[0047] Figure 5 This is a schematic diagram of the housing in the fourth embodiment of the diatomaceous earth filter of this application, as shown. Figure 5 As shown, a valve 112 is provided on the opening 111. The valve 112 and the ultrasonic generator 161 are electrically connected to the external power supply 300. The external power supply 300 controls the valve 112 and the ultrasonic generator 161 to open or close simultaneously.

[0048] In this embodiment, a valve 112 is provided on the opening 111 at the bottom of the housing 110. The valve 112 controls the opening or closing of the opening 111. Furthermore, the valve 112 and the ultrasonic generator 161 are connected to the external power supply 300 to form an interlocked control.

[0049] When the external power supply 300 is turned on, the valve 112 opens quickly, the ultrasonic generator 161 starts to work, and the ultrasonic vibration emitted by the ultrasonic transducer 162 promotes the separation of diatomaceous earth. The fallen diatomaceous earth falls to the outside through the opened opening 111.

[0050] When the external power supply 300 is turned off, valve 112 will close in time, and ultrasonic generator 161 will stop working, vibration will stop, and the entire filtration process will stop in an orderly manner.

[0051] With the external power supply 300 interlocked with the valve 112 and the ultrasonic generator 161, the external power supply 300 is turned on when the valve 112 is opened, and the ultrasonic generator 161 can start working; when the valve 112 is closed, even if the external power supply 300 is accidentally turned on, the ultrasonic generator 161 will not start, further improving the safety and reliability of the diatomaceous earth filter 100.

[0052] Figure 6 This is a schematic diagram of the housing in the fifth embodiment of the diatomaceous earth filter of this application, as shown. Figure 6 As shown, the diatomaceous earth filter 100 also includes a collection device 400, which is connected to the opening 111.

[0053] The difference between this embodiment and the previous embodiment is that a collection device 400 is also connected at the opening 111 at the bottom of the housing 110. The collection device 400 can be a collection bag or a collection box.

[0054] The collection device 400 can recover the diatomaceous earth that falls from the opening 111, preventing it from falling into the external environment and causing pollution.

[0055] A sealing gasket can be provided at the connection between the collecting device 400 and the opening 111 to ensure the sealing of the connection and prevent leakage of diatomaceous earth.

[0056] Figure 7 This is a schematic diagram of the first embodiment of the filtering system of this application, as shown. Figure 7 As shown in the illustration, this application also discloses a filtration system 10, including a control device 200. The filtration system 10 further includes the aforementioned diatomaceous earth filter 100, and the control device 200 is connected to the diatomaceous earth filter 100. By controlling the opening and closing of the diatomaceous earth filter 100 through the control device 200, operation can be stopped promptly when the diatomaceous earth filter 100 malfunctions or requires maintenance, thus avoiding affecting the normal operation of the entire filtration system 10. In addition, the control device 200 can also adjust the operating parameters of the diatomaceous earth filter 100 according to actual operating conditions, thereby improving filtration efficiency and extending the service life of the equipment.

[0057] In the traditional filtration system 10, the diatomaceous earth filter 100 has a long unloading time, and the filter cloth sleeve 180 is easily damaged, which increases the cost of filter media and easily causes abnormal copper foil quality.

[0058] Based on the above problems, this application improves the diatomaceous earth filter 100 in the filtration system 10. By installing a vibrator 160 in the housing 110 of the diatomaceous earth filter 100 and connecting the plum blossom tube 170 below the vibrator 160, when the diatomaceous earth filter 100 is in the first state, the vibrator 160 starts and generates vibration, which is transmitted to the plum blossom tube 170, thereby causing the filter cloth sleeve 180 sleeved on the plum blossom tube 170 to vibrate together. As the filter cloth sleeve 180 vibrates, the diatomaceous earth attached to its surface is quickly shaken off. The shaken-off diatomaceous earth can fall smoothly through the opening 111 at the bottom of the housing 110, thereby quickly completing the soil unloading operation. Since the method of using the plum blossom tube 170 to vibrate the filter cloth sleeve 180 causes less damage to the filter cloth sleeve 180, the soil unloading time can be shortened while reducing damage to the filter cloth sleeve 180, further improving the working efficiency of the filtration system 10.

[0059] Figure 8This is a schematic diagram of a second embodiment of the filtering system of this application, as shown below. Figure 8 As shown, the control device 200 also includes a frequency controller 210, which is wirelessly connected to the first pressure sensor 116 and the second pressure sensor 114 respectively. The frequency controller 210 adjusts the output frequency of the ultrasonic generator 161 according to the pressure difference between the inlet 113 and the outlet 115 detected by the first pressure sensor 116 and the second pressure sensor 114.

[0060] The difference between this embodiment and the previous embodiment is that in this embodiment, a frequency controller 210 is set up, and the frequency controller 210 establishes a connection with the first pressure sensor 116 and the second pressure sensor 114 through a wireless signal. The wireless signal can be a WIFI signal, a Bluetooth signal, a 2.4 GHz signal, etc.

[0061] The first pressure sensor 116 detects the pressure at the inlet 113 of the diatomaceous earth filter 100, and the second pressure sensor 114 detects the pressure at the outlet 115 of the diatomaceous earth filter 100. When the first pressure sensor 116 and the second pressure sensor 114 transmit the detection signals to the frequency controller 210, the frequency controller 210 calculates the pressure difference between the two pressure sensors to determine the current thickness of the diatomaceous earth layer 190. Based on this, the corresponding frequency signal can be adjusted to the ultrasonic generator 161 according to the actual diatomaceous earth thickness. The ultrasonic generator 161 then adjusts the corresponding output frequency according to the received signal, thereby controlling the vibration frequency of the ultrasonic transducer 162. In this way, for diatomaceous earth of different thicknesses, the plum blossom tube 170 and the filter cloth sleeve 180 can obtain vibration at the corresponding frequency, ensuring that diatomaceous earth of different thicknesses can be effectively shaken off, thereby improving the unloading effect.

[0062] When the pressure difference is small, the thickness of the diatomaceous earth on the surface may be moderate. In this case, the frequency controller 210 will appropriately reduce the output frequency of the ultrasonic generator 161. This reduces unnecessary energy consumption and lowers operating costs. On the other hand, it also prevents excessively high-frequency ultrasonic waves from causing unnecessary damage to components such as the filter cloth sleeve 180, thus extending their service life.

[0063] When the pressure difference is large, it indicates that the diatomaceous earth layer 190 is thick. At this time, the frequency controller 210 will increase the output frequency of the ultrasonic generator 161. The high-frequency ultrasonic waves can generate stronger vibrations, more effectively shaking off the diatomaceous earth on the surface of the filter cloth cover 180, thereby quickly completing the soil unloading work and improving the operating efficiency of the filtration system 10.

[0064] It should be noted that the inventive concept of this application can form many embodiments, but due to the limited space of the application documents, they cannot all be listed. Therefore, without conflict, the embodiments described above or the technical features can be arbitrarily combined to form new embodiments. After the embodiments or technical features are combined, the original technical effect will be enhanced.

[0065] The above description, in conjunction with specific optional embodiments, provides a further detailed explanation of this application and should not be construed as limiting the specific implementation of this application to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of this application, and all such modifications or substitutions should be considered within the scope of protection of this application.
