Description

Technical Field

[0001] This invention relates to the field of container cleaning equipment technology, and more particularly to a container interior cleaning equipment. Background Technology

[0002] A shipping container is a modular tool that can carry packaged or unpackaged goods for transport and is easy to load and unload using mechanical equipment. The greatest success of the container lies in the standardization of its products and the entire transportation system established as a result. The fact that a behemoth weighing tens of tons can be standardized and, based on this, gradually realize a global logistics system that integrates ships, ports, shipping routes, highways, transfer stations, bridges, tunnels, and multimodal transport is indeed one of the greatest miracles created by mankind in history. Existing containers are classified according to their uses into dry cargo containers, bulk cargo containers, liquid cargo containers, refrigerated containers, and some special-purpose containers, such as car containers, livestock containers, and hide containers.

[0003] In light of the above, it should be noted that: due to the different types of goods loaded and transported inside containers, some cargo residue remains during transportation and loading / unloading. This residue is susceptible to changes in quality due to temperature, humidity, and other factors, which can severely corrode subsequent cargo. Existing cleaning devices for container interiors discharge wastewater and impurities directly to the outside during cleaning, causing pollution to the surrounding environment. Additionally, water stains and residues are likely to remain on the bottom of the container. Furthermore, the large internal space of existing containers requires significant manpower and resources for overall cleaning, and the entire cleaning process takes a considerable amount of time, severely impacting the efficiency of continuous container use.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a container interior cleaning device to address the problem that, depending on the type of cargo loaded and transported inside the container, some cargo residue remains during transportation and loading / unloading. This residue is susceptible to changes in quality due to temperature, humidity, and other factors, which can severely corrode subsequent cargo. Existing container interior cleaning devices discharge wastewater and impurities collected inside the container directly, causing environmental pollution and leaving water stains and residue on the bottom of the container.

[0011] Preferably, the bottom of the side cleaning frame is sleeved with the push cylinder, and the top of the side cleaning frame is slidably embedded with a telescopic cylinder. The top of the telescopic cylinder is provided with a rotary cylinder connected to the irregular frame. The irregular frame is embedded with a servo motor that is connected to the reciprocating threaded rod. A counterweight is snapped onto the side of the irregular frame away from the reciprocating threaded rod. A guide rod penetrating the cleaning cylinder is symmetrically provided on the top of one side of the irregular frame.

[0012] Preferably, a rotary motor is installed inside the cleaning cylinder, and a cleaning brush sleeve that is connected to the rotary motor is sleeved around the periphery of the cleaning cylinder.

[0013] Preferably, a plurality of long brushes are provided on the outer wall of one end of the rotating frame, and a rotating motor is provided at the other end of the rotating frame and sleeved with the main beam. A plurality of gears are provided on the inner wall of the gear ring and mesh with the output end of the rotating motor. An adjusting cylinder is provided on the outer wall of the gear ring and sleeved with the rotating disk, and the two outer walls of the adjusting cylinders near the gear ring are slidably connected to the inner wall of the rotating frame.

[0014] Preferably, a plurality of short brushes are provided in the middle of the outer wall of one end of the rotating disk, an annular nozzle is provided around the edge of the outer wall of one end of the rotating disk, and a rotating motor is rotatably connected to the middle of the other end of the rotating disk, and the rotating motor is sleeved with the adjusting cylinder.

[0015] A method for operating a container truck interior cleaning device includes the following steps:

[0016] Step 1: Move the container closer to the main beam, and push the support seat closer to the container via the moving platform until the rotating frame touches the inner end face of the container. The rotating motor drives the rotating frame to rotate along the end face of the main beam via the coupling. At the same time, the rotating motor drives the rotating disk to rotate via the coupling. The rotating frame and rotating disk work together to brush the inner end face of the container. The push cylinder drives multiple sets of side cleaning frames to move synchronously into the container inlet. The telescopic cylinder drives the special frame to extend and move until the cleaning cylinder touches the side of the inner cavity of the container and performs roller brush cleaning on the side of the inner cavity of the container. After cleaning is completed and the side cleaning frame returns to its original position along the main beam and detaches from the container, the extension cylinder drives the scraper to slide down until it touches the bottom wall of the inner cavity of the container and moves along the main beam towards the filter bracket. The water and impurities accumulated at the bottom of the inner cavity of the container are pushed into the trough by the scraper. The trough separates the impurities through the filter frame, which constitutes the internal cleaning operation of the container.

[0017] Step Two: When the rotating frame abuts against the inner end face of the container, the rotating motor one drives the rotating frame to rotate via the coupling. The long brush on the rotating frame rubs and scrubs the inner end face of the container. At the same time, the rotating motor one drives the gear ring to rotate along the inner wall of the rotating frame via the coupling and gear. The gear ring drives multiple sets of adjusting cylinders to rotate synchronously. The adjusting cylinders drive the rotating disk to move away from the rotating frame. During this process, the rotating motor two drives the rotating disk to rotate via the coupling. The rotating disk drives the short brush to slide and rub against the inner end face of the container. The annular nozzle is connected to the water pump and the exhaust fan via pipes. During the rotation cleaning process, the water pump pressurizes and delivers cleaning fluid to the annular nozzle to wet and rinse the inner end face of the container. When the rotation cleaning is completed, the annular nozzle disconnects the water pump via the valve and connects to the exhaust fan. The exhaust fan provides high-pressure airflow to the annular nozzle via pipes. The annular nozzle continues to rotate and guides the high-pressure airflow to perform pneumatic cleaning of the inner end face of the container.

[0018] Step 3: When the side cleaning frame abuts against the inner walls of one side of the container opening, the servo motor drives the reciprocating threaded rod to rotate via the coupling. The slider slides along the threaded grooves on the surface of the reciprocating threaded rod and pulls the sleeve rod to slide laterally along the surface of the guide rod. At the same time, it drives the cleaning cylinder to slide laterally along the surface of the guide rod. The rotary motor drives the cleaning brush sleeve to rotate around the perimeter of the cleaning cylinder via the coupling. The telescopic cylinder drives the special-shaped frame away from the main beam until the cleaning cylinder abuts against the inner walls of the container. The cleaning cylinder performs reciprocating roller cleaning on the inner walls of the container one by one. At the same time, multiple sets of water spray frames are connected to the water pump and exhaust fan via pipes. The cleaning fluid in the water tank is guided to the spray frame, which then guides and sprays it onto the inner walls of the container. This, in conjunction with the cleaning cylinder, cleans the container. The rotary cylinder drives the special-shaped frame to rotate at a constant speed around the telescopic cylinder, which in turn drives the side cleaning frame to move laterally along the surface of the main beam towards one end of the rotating frame. This causes the cleaning cylinder to thoroughly clean the inner walls of the container. When the cleaning is complete, the spray frame disconnects the water pump via a valve and connects to the exhaust fan. The exhaust fan provides high-pressure airflow to the spray frame through pipes. The spray frame continuously sprays high-pressure airflow onto the inner walls of the container to quickly remove residual water and sludge from their surfaces.

[0019] Step 4: When the support base is docked with the container, the lifting cylinder drives the filter bracket to slide up until the filter bracket abuts against the bottom of the outer wall of the container opening. The heater regulates and heats the cleaning fluid drawn by the water pump and the high-pressure airflow drawn by the exhaust fan, providing hot and cold cleaning fluid and hot and cold high-temperature and high-pressure airflow to the annular nozzle, water spray frame and strip nozzle respectively, so as to achieve mixed humidification cleaning, high-temperature disinfection and pneumatic drying and sterilization treatment of the container interior.

[0020] Step 5: After the side cleaning rack and rotating rack have completed cleaning the inside of the container, the extension cylinder drives the movable scraper to slide and unfold along one end of the scraper until the side of the multiple movable sliding plates away from the scraper slides against the inner walls of both sides of the container. The tension cylinder drives the scraper to slide down until the bottom of the scraper abuts against the bottom wall of the container cavity. The push cylinder drives the scraper to slide along one end of the container cavity near the filter bracket. When the scraper moves along the bottom of the container cavity for the first time and approaches the filter bracket, the injection port is connected to the water pump through the fittings. The water pump provides cleaning fluid to the strip nozzles through the valves, fittings and injection port. The hydraulic flushing pushes the sewage and impurities collected at the bottom of the container cavity and pushes them into the filter bracket. After the scraper is reset and the bottom of the container is cleaned a second time, the fittings are adjusted by the valves to close the connection between the strip nozzles and the water pump, and open the connection between the strip nozzles and the exhaust fan. The exhaust fan provides high-pressure airflow, and the scraper performs pneumatic cleaning and drying of the bottom wall of the container cavity.

[0021] Step Six: When the scraper pushes and guides the sewage and impurities into the filter bracket, the sewage and impurities are intercepted and filtered by the filter bracket. The impurities are intercepted by the filter plate and remain at the top of the trough. The filtered sewage flows into the drain outlet along the bottom of the trough and then into the water tank along the drain outlet and the return pipe. When the rotary cylinder is activated, it drives the flap to flip downward. One end of the filter plate loses the support of the flap and the other end slides downward along the surface of the flap until the impurities intercepted on the filter bracket are discharged out through the hole after the flap rotates.

[0022] The beneficial effects of this invention are:

[0023] (1) This invention uses the filter bracket and the scraper frame to scrape and push the sewage and impurities in the container after cleaning. The water pump and air pump are used to assist the strip nozzle to process the collected sewage and impurities in a two-step process. The process consists of liquid flushing and concentrated external slag removal, followed by air-push drying and sterilization. The filter bracket is used to separate the discharged sewage and impurities by gravity, effectively realizing the recycling and reuse of the cleaning liquid. The structure of the flap and the filter frame is linked to achieve quantitative tilting and external discharge of the intercepted solid impurities.

[0024] (2) The side cleaning frame, rotating frame and main beam structure are used in conjunction. The reciprocating threaded rod and guide rod are used to drive the cleaning cylinder to move back and forth in a directional manner and to perform local reciprocating cleaning on the inner walls of the container. The rotating cylinder and telescopic cylinder are linked to drive the reciprocating cleaning cylinder to adjust the roller brush along the inner walls of the container. The rotating frame and rotating disk are linked to contact the inner cavity end face of the container. The short brush and long brush are matched to complete the comprehensive roller combing of the inner cavity end face of the container. It and the side cleaning frame form an adaptive moving roller brush cleaning for the inner cavity of containers of different lengths. Attached Figure Description

The rotating frame 5 and the rotating disk 504 work together to brush the inner cavity end face of the container. The push cylinder 301 drives multiple sets of side cleaning frames 4 to move synchronously into the container inlet. The telescopic cylinder 401 drives the special frame 403 to extend and move until the cleaning cylinder 406 abuts against the inner cavity side of the container and performs roller brush cleaning on the inner cavity side of the container. After cleaning is completed and the side cleaning frame 4 returns to its original position along the main beam 3 and detaches from the container, the extension cylinder drives the scraper frame 6 to slide down until it abuts against the bottom wall of the inner cavity of the container and moves along the main beam 3 towards the filter bracket 2. The water and impurities accumulated at the bottom of the inner cavity of the container are pushed into the drain trough 205 by the scraper frame 6. The drain trough 205 separates the impurities through the filter frame 204, which constitutes the internal cleaning operation process of the container.

The cleaning cylinder 406 then cleans the container. The rotary cylinder 402 drives the shaped frame 403 to rotate at a constant speed around the telescopic cylinder 401. This drives the cylinder 301 to move the side cleaning frame 4 laterally along the surface of the main beam 3 towards one end of the rotating frame 5, causing the cleaning cylinder 406 to thoroughly clean the inner walls of the container. When cleaning is complete, the spray frame 407 disconnects the water pump 103 via a valve and connects to the exhaust fan 104.

A second rotating motor 508 is rotatably connected to the middle of the other end of the rotating disk 504, and the second rotating motor 508 is sleeved with an adjusting cylinder 503. When the rotating frame 5 abuts against the end face of the container's inner cavity, the first rotating motor 501 drives the rotating frame 5 to rotate via a coupling. The long brushes 502 on the rotating frame 5 rub and scrub against the end face of the container's inner cavity, while simultaneously rotating... Motor 501 drives gear ring 507 to rotate along the inner wall of rotating frame 5 via coupling and gear. Gear ring 507 drives multiple sets of adjusting cylinders 503 to rotate synchronously. Adjusting cylinders 503 drive rotating disk 504 to move away from rotating frame 5. During this process, motor 508 drives rotating disk 504 to rotate via coupling. Rotating disk 504 drives short brush 506 to slide and rub against the inner end face of container cavity. Annular nozzle 505 is connected to water pump 103 and exhaust fan 104 via pipe fittings. During the rotation cleaning process, water pump 103 pressurizes and delivers cleaning fluid to annular nozzle 505 to wet and rinse the inner end face of container cavity.

Annular nozzle 505 continues to rotate and guides high-pressure airflow to perform pneumatic cleaning of the inner end face of container cavity.

[0049] Combining Embodiment 1 and Embodiment 2, the filter bracket 2 can be used to perform gravity-based solid-liquid separation of discharged wastewater and impurities, effectively realizing the recycling and reuse of cleaning liquid. The structural linkage between the flap 203 and the filter frame 204 enables the quantitative tilting and outward discharge of intercepted solid impurities. Furthermore, the rotating frame 5 and the rotating disk 504 are structurally linked to contact the inner cavity end face of the container, and the short brush 506 and long brush 502 work together to complete the comprehensive roller combing of the inner cavity end face of the container. Together with the side cleaning frame 4, it forms an adaptive moving roller brush cleaning system for the interior of containers of different lengths.
