Description

Technical Field

[0001] This invention relates to the field of chemical tanker cleaning equipment technology, specifically a chemical tanker cleaning device with multi-angle adjustment function. Background Technology

[0002] Chemical tankers are special vessels designed for transporting liquid chemicals. They are mainly used to carry petrochemical products, liquid fertilizers, inorganic chemicals, and other dangerous liquid cargoes that are corrosive, toxic, or flammable and explosive. Because different chemicals have strict requirements for purity and environmental conditions, the cargo holds and pipeline systems usually need to be thoroughly cleaned after loading and unloading operations to avoid residual media affecting subsequent transportation.

[0003] Currently, cleaning chemical tankers usually requires manual cleaning. Due to the large size and complex structure of chemical tankers, manual labor is very demanding. In addition, there are blind spots in areas that are difficult for manual labor to reach, such as the top, bottom, and corners of the tank, resulting in incomplete cleaning. When the tank is cleaned and enters the drying stage, a large amount of high-temperature airflow with residual heat is generated. If it is discharged directly, it will result in energy waste. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that manual cleaning of ship cabins is arduous, has poor cleaning effect and causes energy waste. The present invention provides a chemical ship cleaning device with multi-angle adjustment function.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A cleaning device includes a base plate, wheels mounted on one side of the base plate, a spraying device mounted above the base plate, and a drying device mounted on one side of the spraying device. The drying device is mounted on the base plate, and a housing is installed on the outside of the spraying device and the drying device, with heat dissipation vents on the housing. The spraying device can spray cleaning fluid onto the cargo hold of the chemical tanker from multiple angles, ensuring that the cleaning fluid is evenly sprayed onto the residual chemicals. The drying device can recover the hot air sprayed during drying, allowing the cleaning fluid to be fully heated before spraying, improving the cleaning fluid's solubility and cleaning effect on chemical residues. Simultaneously, the heating of the cleaning fluid utilizes recovered waste heat, eliminating the need for additional energy consumption and reducing energy costs.

[0006] The spraying device includes a support plate, which is mounted on a base plate. A drive device is mounted above the support plate, a swing device is mounted on one side of the drive device, and a rotating device is mounted below the swing device. The rotating device is mounted on the support plate.

[0007] The drive unit includes a horizontal plate, with a large gear mounted below it. The large gear is mounted on a support plate. A cylinder is mounted below the horizontal plate, rotating on the large gear. A first transmission gear and a spring are mounted on one side of the cylinder, with one end of the spring mounted on a base plate. A motor bracket and a vertical plate are mounted above the horizontal plate. A servo motor is mounted on the motor bracket and connected to the control system. The control system starts the servo motor, and the output shaft of the servo motor drives the first connecting rod to rotate.

[0008] The swinging device includes a first connecting rod mounted on the output shaft of a servo motor. A second connecting rod is rotatably mounted on one side of the first connecting rod, and a third connecting rod is rotatably mounted on one side of the second connecting rod. A support column is connected to one side of the vertical plate, and the third connecting rod rotates on the support column. A nozzle pipe is mounted on one side of the third connecting rod, and a nozzle is mounted on one side of the nozzle pipe. The first connecting rod drives the second connecting rod to rotate, which in turn drives the third connecting rod to swing up and down. The third connecting rod, in turn, drives the nozzle pipe to swing up and down, which in turn drives the nozzle to swing up and down, allowing the sprayed cleaning fluid to thoroughly clean both the upper and lower parts of the device.

[0009] The rotating device includes a first bevel gear mounted on the output shaft of a servo motor. A support plate is mounted on one side of the vertical plate, and a second bevel gear is rotatably mounted on the support plate. A first limit block is mounted on the inner side of the second bevel gear. A transmission column is rotatably mounted on the support plate, and a small gear is mounted on one end of the transmission column. The small gear meshes with a large gear. A cam is mounted on the output shaft of the servo motor, located above the transmission column. The output shaft of the servo motor drives the first bevel gear and the cam to rotate. The first bevel gear drives the second bevel gear to rotate. When the flange of the cam contacts the transmission column, the nozzle has completed vertical spraying. The second bevel gear drives the transmission column to rotate, which in turn drives the small gear to rotate. The small gear rotates around the large gear. The transmission column drives the support plate to rotate on the large gear. The support plate drives the vertical plate to rotate, which in turn drives the horizontal plate to rotate on the large gear. The horizontal plate drives the cylinder to rotate, which in turn drives the first transmission gear and the spring to rotate. This changes the horizontal spraying angle of the nozzle. When the base circle of the cam contacts the transmission column, the spring drives the cylinder to rotate back to its initial position, and the nozzle returns to its initial spraying angle.

[0010] The transmission column includes a column body that rotates on a support plate. The column body has a groove and a sliding groove inside. The sliding groove is located above the groove. A first wedge block is slidably installed inside the groove. A second limiting block is connected to one side of the first wedge block. The second limiting block is located inside the second bevel gear. A return spring is installed between the first wedge block and the groove. The return spring is sleeved on the second limiting block. A second wedge block is slidably installed in the sliding groove. A cam is located above the second wedge block. When the cam flange contacts the drive column, the cam drives the second wedge block to slide away from the cam in the sliding groove. The second wedge block drives the first wedge block to move away from the center of the second bevel gear in the groove. The first wedge block drives the second limiting block to move away from the center of the second bevel gear. At this time, the second limiting block contacts the first limiting block. The second bevel gear drives the column to rotate. When the base circle of the cam contacts the drive column, the return spring drives the first wedge block back to the initial position. The first wedge block drives the second wedge block and the second limiting block back to the initial position. The second limiting block and the first limiting block disengage, and the column stops rotating.

[0011] The drying unit includes an air outlet mounted on a base plate. A liquid storage tank is installed on one side of the air outlet, and a recovery device is installed above the liquid storage tank. A liquid outlet pipe with a spiral tube is installed on one side of the liquid storage tank, and a water pump is installed on one side of the liquid storage tank. The liquid outlet pipe and the water pump are connected by a pipeline, and the water pump and the nozzle pipe are connected by a flexible hose. The water pump is connected to the control system. When the water pump is started, it draws the cleaning solution from the storage tank into the nozzle pipe, where it is sprayed out through the nozzle.

[0012] The air outlet device includes a base mounted on a base plate. A rotating column is rotatably mounted on the base. An air outlet box is mounted on one side of the rotating column, and a first air outlet pipe is mounted on one side of the air outlet box.

A sixth bevel gear is installed at one end of the third rotating shaft, and the fifth and sixth bevel gears mesh. A third fan is installed at the other end of the third rotating shaft. The second air outlet and the air outlet box are connected by a pipe, as are the second air inlet and the air inlet box. The second air inlet and the spiral tube are connected by a pipe. The electric heating element is connected to the control system. The heating element is controlled to generate heat. The output shaft of the servo motor drives the universal joint to rotate, which in turn drives the first shaft to rotate. The first shaft then drives the third bevel gear and the second fan to rotate. The second fan exhausts the hot air from the heating chamber into the exhaust box, which in turn exhausts it into the first exhaust pipe. The hot air drives the first fan to rotate, which in turn drives the connecting column to rotate. The connecting column then drives the exhaust cover to rotate, ensuring that the exhaust hot air is evenly sprayed onto the inner wall of the cabin. Simultaneously, the third bevel gear drives the fourth bevel gear to rotate, which in turn drives the second shaft to rotate. The second shaft then drives the fifth bevel gear to rotate, which in turn drives the sixth bevel gear to rotate. The sixth bevel gear then drives the third shaft to rotate, which in turn drives the third fan to rotate. The third fan draws the dried hot air into the first intake pipe, through the intake box, into the second intake pipe, and finally into the spiral tube. The residual heat in the hot air heats the cleaning fluid in the outlet pipe, improving the cleaning effect of the cleaning fluid.

[0014] The blades of the second fan and the third fan rotate in opposite directions, and the heating box is made of heat-insulating material.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention adopts multi-angle adjustment technology, which can flexibly change the horizontal and vertical angles of the nozzles as needed during the cleaning process, thereby achieving all-round coverage spraying of the interior of the chemical tanker. It can effectively clean the top, bottom and corners of the tanker, which are difficult to reach by humans, ensuring that residual chemicals are thoroughly rinsed and removed, avoiding cross-contamination or safety hazards caused by incomplete local cleaning, and eliminating the need for direct manual intervention in the cleaning operation, thus significantly reducing labor intensity. 2. This invention uses waste heat recovery technology, which can recover the hot air sprayed during drying and guide it to the outside of the cleaning liquid spray pipe through a heat-conducting structure, so that the cleaning liquid can be fully heated before being sprayed, thereby improving the solubility and cleaning effect of the cleaning liquid on chemical residues. At the same time, the heating of the cleaning liquid utilizes the recovered waste heat, without the need for additional energy consumption, thus reducing energy usage costs.
