Low-speed engine EGC electric control box

Abstract

This utility model relates to the field of electrical control box technology, and provides a low-speed EGC electrical control box, including a box body, on which are provided several exhaust fans and an air inlet. The air inlet is provided with a filter screen and a dust removal mechanism for cleaning dust from the filter screen. The dust removal mechanism includes a frame, an electrostatic plate disposed on the frame for electrostatically adsorbing dust from the filter screen, and a cleaning component for cleaning the dust adsorbed on the electrostatic plate. The dust cleaning action of the filter screen is specifically as follows: the frame body is driven to move along the filter screen direction by the driving component, causing the electrostatic plate to move across the filter screen accordingly. The dust adhering to the filter screen is adsorbed onto the electrostatic plate using electrostatic adsorption. Then, the cleaning component cleans the dust adsorbed on the electrostatic plate, keeping the electrostatic plate clean to ensure electrostatic dust collection effect. This adsorption-based cleaning of dust from the filter screen prevents dust from embedding in the filter holes, thus ensuring the long-term unobstructed flow of the filter screen.

Description

Technical Field

[0001] This utility model relates to the field of electrical control box technology, specifically a low-speed EGC electrical control box. Background Technology

[0002] EGC (Exhaust Gas Cleaning System) is a core system for meeting the International Maritime Organization's sulfur emission limits. Its electrical control box, as the control center of the EGC system, is required to operate stably for a long time in the harsh engine room environment.

[0003] Currently, low-speed EGC control boxes are typically equipped with exhaust fans and corresponding air inlets to meet heat dissipation requirements through forced convection. Air inlets often have filters to remove dust from the air. Over time, dust inevitably accumulates on these filters, gradually clogging the pores and affecting air intake efficiency and heat dissipation. To address this issue, mechanical methods such as brushes or scrapers are often used to clean the filters. However, because the brushes or scrapers directly contact the filter surface during cleaning, they compress dust, causing some dust to embed into the filter pores. Over time, this forms a stubborn blockage layer, severely affecting the filter's patency.

[0004] Therefore, this utility model proposes a low-speed EGC electrical control box to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a low-speed EGC electrical control box to solve the above-mentioned problems.

Detailed Implementation

[0026] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] Please see Figure 1A low-speed EGC electrical control box includes a box body 1, on which a plurality of exhaust fans 2 and an air inlet are provided. The air inlet is provided with a filter screen 3 and a dust removal mechanism for cleaning dust on the filter screen 3. The dust removal mechanism includes a frame 4 located on the side of the filter screen 3, an electrostatic plate 5 located on the frame 4 for electrostatically adsorbing dust on the filter screen 3, and a cleaning component 6 for cleaning the dust adsorbed on the electrostatic plate 5. The EGC electrical control box also includes a drive component for driving the frame 4 to move along the direction of the filter screen 3.

[0028] It should be noted that the frame 4 is equipped with an electrostatic generator (not shown in the figure) electrically connected to the electrostatic plate 5, so that the electrostatic plate 5 is charged with static electricity to attract dust; in addition, the dust removal mechanism can be automatically started periodically, such as automatically starting every 10 days, 20 days or other intervals to clean the dust on the filter screen 3 (the corresponding control technology is the prior art), or it can be manually started by the user according to the dust adhesion on the filter screen 3. This application does not limit it here.

[0029] The dust cleaning action of filter screen 3 is as follows: the drive component drives the frame 4 to move along the direction of filter screen 3, thereby causing the electrostatic plate 5 to move across filter screen 3 accordingly. The dust adhering to filter screen 3 is adsorbed onto electrostatic plate 5 by electrostatic adsorption. Then, the cleaning component 6 cleans the dust adsorbed on electrostatic plate 5, so that electrostatic plate 5 is kept clean to ensure the electrostatic dust collection effect. The dust on filter screen 3 is cleaned by electrostatic adsorption, and there is no situation where dust is embedded in the filter holes, thereby ensuring the long-term unobstructed flow of filter screen 3.

[0030] Please see Figures 1-6 In one embodiment of the present invention, the electrostatic plate 5 is rotatably mounted on the frame 4, and the frame 4 is provided with a first driving member 9 for driving the electrostatic plate 5 to rotate (the first driving member 9 is a servo motor, divider, etc. in the prior art). The cleaning component 6 includes a mounting base 601 that is movably mounted in the frame 4, a scraper 603 mounted on the mounting base 601, and a dust collection box 8 that is detachably mounted on the frame 4. The dust collection box 8 is open on the upper side and located below the electrostatic plate 5.

[0031] The inner wall of the frame 4 is provided with at least one vertically oriented slot 605. The mounting base 601 is provided with a protrusion 606 corresponding to the slot 605. The protrusion 606 is slidably engaged in the corresponding slot 605. The frame 4 is provided with a second threaded rod 604 and a second driving component 602 for driving the second threaded rod 604 to rotate (the second driving component 602 is a servo motor, geared motor, etc. in the prior art). The second threaded rod 604 passes through the mounting base 601 in a threaded engagement manner.

[0032] The mounting base 601 is provided with a slot 607 adapted to the scraper 603. The side of the scraper 603 away from the electrostatic plate 5 is inserted into the slot 607, and a number of elastic elements 608 (such as springs and rubber columns in the prior art) are provided between the bottom of the slot 607 and the scraper 603. The scraper 603 is provided with a bevel 609 on the side close to the electrostatic plate 5.

[0033] The frame 4 has an insertion port 10 on one side that fits the dust collection box 8. A baffle 11 is rotatably mounted at the insertion port 10 to limit the movement of the dust collection box 8. A torsion spring 12 is provided at the rotatable connection between the baffle 11 and the frame 4. The dust collection box 8 is inserted into the frame 4 through the insertion port 10, similar to a drawer. In the absence of external force, the baffle 11 is in a vertical position under the action of the torsion spring 12, thus blocking the front of the dust collection box 8 (within a certain range). Figure 6 (The angle shown is used for explanation) to limit the position of the dust collection box 8. When the dust in the dust collection box 8 reaches a certain amount and needs to be removed and emptied for cleaning, the baffle 11 is moved so that it no longer blocks the dust collection box 8. The dust collection box 8 can be pulled out while maintaining the current state. The dust collection box 8 is also provided with a corresponding handle to facilitate the insertion operation.

[0034] In this embodiment, after the electrostatic plate 5 adsorbs the dust on the filter screen 3, the first driving component 9 drives the electrostatic plate 5 to rotate 180° (to... Figure 1 (The angle shown is used for explanation) so that the adsorption side faces the scraper 603, and then the second threaded rod 604 is driven to rotate by the second driving member 602, which drives the mounting base 601 to move downward, that is, drives the scraper 603 to move downward accordingly. During the downward stroke of the scraper 603, the side of it away from the mounting base 601 will come into contact with and adhere to the electrostatic plate 5, thereby scraping the dust adsorbed on the electrostatic plate 5 and collecting it in the dust collection box 8. It should be noted that the purpose of setting the elastic member 608 and the bevel 609 is to keep the side of the scraper 603 away from the mounting base 601 in close contact with the electrostatic plate 5, thereby ensuring that the scraper 603 can effectively scrape off the dust adsorbed on the electrostatic plate 5.

[0035] Please see Figure 1 and Figure 7 In one embodiment of this utility model, the frame 4 is provided with a cylindrical cavity 13, which is located below the scraper 603. The scraper 603 is provided with an electromagnet 19 and a magnetic block 18 from bottom to top. The magnetic poles of the magnetic block 18 and the electromagnet 19 are divided into upper and lower halves. When the electromagnet 19 is energized, its upper half magnetic pole is the same as the lower half magnetic pole of the magnetic block 18. The magnetic block 18 is provided with a cylindrical cavity 14, and the upper end of the cylindrical cavity 14 is provided with an impact ball 15. The frame 4 is also provided with an on / off button 16 for controlling the on / off of the electromagnet 19. When the mounting base 601 moves down to the position, the on / off button 16 is triggered. The cylindrical cavity 13 is also provided with a plurality of protrusions 17 for limiting the upward movement of the magnetic block 18.

[0036] In this embodiment, the mounting base 601 moving down to its position means that the scraper 603 has moved down to its position accordingly (without detaching from the electrostatic plate 5), and all the dust on the electrostatic plate 5 has been scraped off. When the mounting base 601 triggers the on / off button 16, the electromagnet 19 is energized and magnetized. Under the action of like poles repelling and unlike poles attracting, the magnetic block 18 is instantly moved upward by the repulsive force of the electromagnet 19, which in turn drives the impact ball 15 to impact the scraper 603, thereby shaking off the dust adhering to the scraper 603, keeping the scraper 603 clean, and thus ensuring the dust scraping effect on the electrostatic plate 5.

[0037] Please see Figure 1 In one embodiment of this utility model, the driving component includes two first threaded rods 7 disposed on the housing 1. Both first threaded rods 7 pass through the frame 4 by means of threaded engagement. A belt drive structure (not shown in the figure) is provided between the two first threaded rods 7. The housing 1 is also provided with a third driving component (not shown in the figure, the third driving component is a servo motor, geared motor, etc. in the prior art) for driving the two first threaded rods 7 to rotate synchronously through the third driving component, thereby driving the frame 4 to move along the direction of the filter screen 3.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
