Description

Technical Field

[0001] This utility model relates to the field of oil drum recycling technology, specifically to an automatic cleaning and drying device for lubricating oil drums. Background Technology

[0002] In the field of industrial equipment maintenance, the recycling and disposal of lubricating oil drums (usually standard 200L metal drums) is a key link in resource recycling. Traditional cleaning methods mainly rely on manual operation: workers need to pour out the residual oil in the drum, manually inject cleaning agent, clean the inner wall by physical shaking or simple brushes, and finally let it air dry. Manual cleaning is inefficient and the natural drying period is long. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model discloses an automatic cleaning and drying device for lubricating oil drums. The technical solution adopted includes a metal drum, a hot air blower, an air outlet pipe and a cleaning agent pipe, a base, a groove, a bottom drain groove, a rolling installation structure, a support roller, a rear rod, a rear groove, a T-block, a lead screw, a lead screw motor, a cleaning shaft, and a drying section. Grooves are opened on the left and right sides of the base, and a bottom drain groove is opened at the bottom of the groove, through which wastewater generated during the cleaning process leaks down. A rolling installation structure is set in the groove, through which the support roller is installed. The lower part of the metal drum is placed on the support roller. During the cleaning process, the rolling installation structure drives the support roller to rotate, thereby rotating the metal drum placed on it, achieving rotational cleaning and ensuring thorough cleaning. A rear rod is fixed in the middle of the rear side of the base, and a rear groove is opened on the rear rod. A lead screw is rotatably installed on the bottom surface of the rear groove, and a lead screw motor is installed on the top of the rear rod. The output shaft of the lead screw motor extends down from the through hole at the top of the rear rod and is fixedly connected to the top of the lead screw, i.e., the lead screw of the lead screw motor... The drive unit, equipped with a T-block, is placed in the rear groove and installed in conjunction with a lead screw. Cleaning shafts are rotatably mounted on the front side of the unit. The side wall of the metal bucket is positioned between two cleaning shafts. Starting the lead screw motor allows for height adjustment of the cleaning shafts to accommodate metal buckets of different diameters, ensuring the metal bucket can be smoothly inserted between the two shafts. A hot air blower is located at the rear of the base, and its outlet pipe connects to a drying section at the front of the rear rod. After cleaning, the externally powered hot air blower dries the inside of the metal bucket through the drying section, improving overall cleaning efficiency. Cleaning agent pipes are located on the protruding plates on the left and right sides of the rear rod, connected to the pump output pipe for delivering the cleaning agent. This structure sprays cleaning agent during cleaning, and a nozzle can be installed at the outlet of the cleaning agent pipe to increase coverage area. This works in conjunction with the cleaning shafts to clean the metal bucket. Regarding the installation of the lead screw, the shaft portion without threaded grooves at its bottom is fitted with a bearing located on the bottom surface of the rear groove. The configuration of the bearing and shaft is mature existing technology and will not be elaborated further.

[0004] As a preferred embodiment of this utility model, the rolling installation structure includes a movable plate, a rotating motor, a rotating shaft, and a knob. The left and right side grooves are connected by a through hole. The left end of the rotating shaft is rotatably connected to the inner wall of the left side groove, and the right end extends from the through hole on the right side wall of the right side groove, with the knob fixed at the extended end. The rotating shaft has symmetrically distributed threaded grooves on both sides. The movable plate is placed in the groove and installed in conjunction with the threaded grooves. The front and rear ends of the movable plate have upward-facing protrusions. A rotating motor is installed on the front side of the front protrusion, driving the rotating shaft mounted between the front and rear protrusions. A support roller is fixed on the shaft, allowing for manual rotation. A knob or an external stepper motor is installed, and the output shaft of the stepper motor is connected to the right end of the rotating shaft to drive the rotating shaft to rotate. With the setting of the threaded groove, the movable plates on the left and right sides move synchronously, which drives the position of the support roller to change, thus successfully supporting the metal barrel. The starting of the rotating motor, which is powered by a battery and controlled by a remote control, drives the support roller to rotate. Under the action of the metal barrel's own weight and the action of the upper side wall of the metal barrel being inserted between the two cleaning shafts, the rotation of the support roller can drive the metal barrel to rotate. In order to make the metal barrel rotate smoothly, friction material can be covered on the outer wall of the support roller to increase friction.

[0005] As a preferred technical solution of this utility model, a hard bristle brush is wrapped around the cleaning shaft.

[0006] As a preferred technical solution of this utility model, the drying section includes a triangular cross-section air duct and an air outlet. A triangular cross-section air duct is fixed at the center of the front side of the rear rod. The air outlet and the triangular cross-section air duct are connected through a through hole opened at the rear rod. Several air outlets are evenly distributed on the inclined surface of the triangular cross-section air duct.

[0007] As a preferred technical solution of this utility model, the protruding part between the grooves on the base has several mounting slots, and the bottom roller is rotatably mounted in the mounting slot. The lead screw motor is powered by a battery and controlled by a remote control device.

[0008] The beneficial effects of this utility model are as follows: By supporting the roller to drive the metal bucket to rotate (in combination with the hard bristles of the cleaning shaft), 360° cleaning is achieved, thoroughly cleaning the bucket wall. The cleaning agent pipeline, together with the spray nozzle, provides a comprehensive spray, improving the utilization rate of the cleaning agent. The screw motor drive, equipped with a T-block, enables stepless adjustment of the cleaning shaft height, making it compatible with 200L standard buckets and deformable containers of different diameters. The hot air blower, combined with the triangular cross-section air duct and multiple air outlets, forms a uniform hot air flow field, reducing the drying time inside the bucket to less than 10 minutes (compared to 24 hours of natural air drying), avoiding the risk of rust.

[0016] The working principle of this utility model is as follows: During use, the metal bucket is placed horizontally on the support rollers on both sides. The knob is manually rotated (or a stepper motor is started) to drive the rotating shaft to rotate. This drives the movable plates on both sides to move inward synchronously through the threaded groove, making the support rollers tightly adhere to the bucket wall. The lead screw motor is then started, driving the lead screw to rotate and lower the T-block until the cleaning shaft is embedded in both sides of the bucket (height adaptation complete). The pump for delivering the cleaning agent is turned on, and the cleaning agent covers the inner wall of the bucket through the cleaning agent pipe and nozzle. The motor drives the support rollers to rotate (the outer friction layer increases adhesion), causing the metal bucket to rotate uniformly around its axis. Friction occurs between the bucket wall and the hard bristles of the cleaning shaft, achieving bidirectional mechanical scraping and thoroughly removing oil stains. After cleaning, the hot air blower is started, and high-temperature airflow enters the triangular cross-section air duct through the air outlet. The evenly distributed air outlets on the inclined surface of the air duct directionally spray the hot air onto the inner wall of the bucket, forming a circulating drying field. The support rollers maintain a low-speed rotation to ensure uniform heating of the bucket wall and rapid evaporation of moisture.
