Description

Technical Field

[0001] This invention relates to the field of air purification technology, specifically to an intelligent energy-saving environmental control and purification device for ships. Background Technology

[0002] As a core component for ensuring the environment of confined spaces, the air purification efficiency and operational stability of shipboard air control systems directly affect the health of personnel and the safety of equipment. Existing shipboard air purification devices generally employ a combination of fixed filters and activated carbon adsorption. Dust, oil mist, and other large particles easily accumulate on the filter surface, leading to a continuous increase in air resistance. This not only reduces ventilation efficiency and increases energy consumption but also requires frequent manual cleaning, making maintenance complex and affecting continuous system operation. Traditional devices lack intelligent monitoring and self-cleaning functions, making it difficult to dynamically adjust operating status based on the degree of filter clogging. Over-filtration or untimely cleaning often results in energy waste or reduced purification effectiveness.

[0003] Especially in special scenarios such as long-distance voyages, limited maintenance resources and harsh operating environments further amplify the above problems. Therefore, it is necessary to develop an environmental control and purification device that integrates intelligent monitoring, automatic cleaning and energy-saving operation. Summary of the Invention

[0004] The main objective of this invention is to provide an intelligent, energy-saving, environmentally friendly purification device for ships that can automatically clean up intercepted impurities.

[0005] To achieve the above objectives, the technical solution provided by this invention is as follows:

[0006] A shipboard intelligent energy-saving environmental control and purification device includes a housing. An air inlet pipe is fixed to one end of the housing, and the outlet end of the air inlet pipe extends into the housing. An air outlet pipe is fixedly connected to the other end of the housing. A fixing ring is concentrically fixed to the outlet end of the air inlet pipe. A fixing sleeve is concentrically fixed to the side of the fixing ring opposite to the air inlet pipe. A filter cartridge is slidably disposed within the housing. A drive assembly is disposed within the housing and connected to the filter cartridge. The fixing ring is located inside one end of the filter cartridge, and its outer edge is slidably sealed to the inner edge of the filter cartridge. An annular scraper is concentrically fixed on the fixing ring, located outside the fixing sleeve, and away from the... One side of the fixing ring is machined with an annular blade. The blade of the scraper contacts the inner wall of the filter cartridge. A cover is concentrically fixed to the other end of the filter cartridge. A connecting plate is concentrically fixed to the end of the cover facing the fixing ring. A guide cavity is formed between the connecting plate and the cover. An annular return channel is formed between the outer edge of the connecting plate and the inner edge of the cover. Multiple air holes are evenly distributed around the circumference of the connecting plate. After the fixing sleeve and the opposite end of the connecting plate are sealed and contacted, the multiple air holes are connected to the fixing sleeve. A drain pipe is fixed on the fixing ring. The drain pipe is connected to the inner cavity of the filter cartridge through a pressure valve. The outlet end of the drain pipe extends to the outside of the shell.

[0007] Specifically, an activated carbon plate is installed inside the housing between the air inlet pipe and the air outlet pipe.

[0008] Specifically, a pad is concentrically fixed inside the cover, and the connecting plate is connected to the cover through the pad.

[0009] Specifically, sliders are fixed at both ends of the filter cartridge and the cap, and the sliders are slidably disposed in the grooves inside the housing.

[0010] Specifically, the drive assembly includes a lead screw rotatably connected inside the housing, the lead screw being parallel to the filter cartridge, the lead screw being threadedly connected to one of the sliders, a motor being fixed to the outside of the housing, the output shaft of the motor being rotatably and sealed to the housing, and the output shaft of the motor being concentrically and fixedly connected to the lead screw.

[0011] Specifically, an air flow sensor is installed inside the air outlet duct, and the air flow sensor, motor, and controller are electrically connected.

[0012] Specifically, a sealing ring is fixed to the end of the fixing sleeve facing the connecting plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. This device monitors in real time through an air flow sensor, which can automatically identify filter cartridge blockage and trigger a cleaning program. It uses a motor to drive the filter cartridge to slide, combined with mechanical scraping by a scraper and high-pressure airflow rinsing, to achieve online self-cleaning of the filter cartridge. No manual disassembly and cleaning is required, which significantly reduces maintenance costs and labor intensity. It is especially suitable for special environments such as ships where maintenance operations are limited.

[0015] 2. This device adopts a dual cleaning mechanism of mechanical scraping and pneumatic sewage discharge. The scraper scrapes off the stubborn impurities adhering to the inner wall of the filter cartridge, and then uses the instantaneous high-pressure airflow generated by the sealing to quickly discharge the scraped impurities into the shell through the sewage discharge pipe, avoiding secondary residue of impurities in the device and ensuring thorough cleaning.

[0016] 3. This device integrates the filtration, detection, drive, and cleaning mechanisms into the housing. It utilizes the sliding displacement of the filter cartridge itself to achieve automatic switching between the filtration and sewage discharge channels, eliminating the need for additional complex valve control. It features a compact structure, reliable operating logic, and adaptability to the installation requirements of ships with limited space. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] like Figures 1-4 As shown, an intelligent energy-saving environmental control and purification device for ships includes a housing 1. An air inlet pipe 2 is fixed to one end of the housing 1, and the outlet end of the air inlet pipe 2 extends into the housing 1. An air outlet pipe 3 is fixedly connected to the other end of the housing 1. An activated carbon plate 11 is installed inside the housing 1 between the air inlet pipe 2 and the air outlet pipe 3. The activated carbon plate 11 can filter the air inside the housing 1.

[0024] A fixing ring 5 is concentrically fixed at the outlet end of the air inlet pipe 2. A fixing sleeve 501 is concentrically fixed on the side of the fixing ring 5 away from the air inlet pipe 2. A filter cartridge 7 is slidably arranged inside the housing 1. The filter cartridge 7 can slide in the left and right directions inside the housing 1.

[0025] The fixing ring 5 is located inside one end of the filter cylinder 7. The outer edge of the fixing ring 5 is slidably and sealed to the inner edge of the filter cylinder 7. A ring-shaped scraper 6 is concentrically fixed on the fixing ring 5. The scraper 6 is located outside the fixing sleeve 501. A ring-shaped cutting edge is machined on the side of the scraper 6 away from the fixing ring 5. The cutting edge of the scraper 6 is in contact with the inner wall of the filter cylinder 7.

[0026] A cover 8 is concentrically fixed to the other end of the filter cartridge 7. A connecting plate 801 is concentrically fixed to the end of the cover 8 facing the fixing ring 5, and a guide cavity 803 is formed between the connecting plate 801 and the cover 8. Specifically, a pad 802 is concentrically fixed inside the cover 8, and the connecting plate 801 and the cover 8 are connected by the pad 802.

[0027] A sealing ring is fixed to the end of the fixed sleeve 501 facing the connecting plate 801.

[0028] An annular return channel 10 is formed between the outer edge of the connecting plate 801 and the inner edge of the cover 8. Multiple air holes 9 are evenly distributed around the circumference of the connecting plate 801. After the fixed sleeve 501 is sealed to the opposite end of the connecting plate 801, the multiple air holes 9 are connected to the fixed sleeve 501. A drain pipe 4 is fixed on the fixed ring 5. The drain pipe 4 is connected to the inner cavity of the filter cartridge 7 through the pressure valve 12. The outlet end of the drain pipe 4 extends to the outside of the housing 1.

[0029] A drive assembly is installed inside the housing 1, and the drive assembly is connected to the filter cartridge 7. Slider 13 is fixed at both ends of the filter cartridge 7 and the upper and lower ends of the cover 8, and the slider 13 is slidably disposed in the slide groove inside the housing 1.

[0030] The drive assembly includes a lead screw 14 rotatably connected inside the housing 1, the lead screw 14 being parallel to the filter cartridge 7, the lead screw 14 being threadedly connected to one of the sliders 13, a motor 15 being fixed on the outside of the housing 1, the output shaft of the motor 15 being rotatably and sealedly connected to the housing 1, and the output shaft of the motor 15 being concentrically and fixedly connected to the lead screw 14.

[0031] An air flow sensor is installed inside the air outlet duct 3. The air flow sensor, motor 15, and controller are electrically connected.

[0032] During operation, air enters the housing 1 through the air inlet duct 2, passes through the filter cartridge 7 for initial filtration of large particulate impurities, and then passes through the activated carbon plate 11 for deep adsorption of organic pollutants. The purified air is then discharged through the air outlet duct 3. The filter cartridge 7 and the fixing ring 5 slide and seal to ensure that all air passes through the filter cartridge 7 for filtration.

[0033] An air flow sensor inside the air outlet duct 3 monitors the air volume in real time. When impurities accumulate on the inner wall of the filter cartridge 7, causing the air volume to drop to the threshold, the controller starts the motor 15. The motor 15 drives the lead screw 14 to rotate, causing the filter cartridge 7 to slide to the left.

[0034] During the leftward movement of the filter cartridge 7, the annular scraper 6 on the fixing ring 5 contacts the inner wall of the filter cartridge 7, and the blade scrapes off the impurities attached to the inner wall of the filter cartridge 7. The scraped-off impurities are temporarily stored in the inner cavity of the filter cartridge 7.

[0035] The filter cartridge 7 moves to the left until the fixed sleeve 501 and the end face of the connecting plate 801 are in sealed contact. The pressure inside the filter cartridge 7 increases, triggering the pressure valve 12 to open. The airflow passes through the fixed sleeve 501, the air hole 9, the guide cavity 803, and the return channel 10 in sequence, carrying the scraped impurities out of the drain pipe 4 and out of the housing 1.

[0036] After the sewage discharge is completed, the motor 15 reverses to drive the filter cartridge 7 to move to the right and reset, restoring the normal filtration state. The air flow sensor continuously monitors and triggers the cleaning process in a cycle.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
