[0002] In existing technologies, the cleaning and drying of stainless steel packaging drums with a capacity of approximately 200L typically presents the following problems:

[0003] Low cleaning efficiency: Traditional cleaning equipment often uses a single cleaning method, such as simple high-pressure spraying, which is not thorough enough for cleaning inside and outside the tank, takes a long time, cannot meet the needs of rapid cleaning, and the cycle time is difficult to control within a short period of time.

[0004] Unstable cleaning quality: The nozzles used have insufficient impact force, and the cleaning cycle is difficult to control precisely, resulting in missed cleaning and repeated cleaning. This leads to inconsistent cleaning quality. The cleaning quality can only be detected by indirect indicators such as the conductivity of the discharged water, which cannot accurately reflect the cleaning effect.

[0005] Large equipment footprint: In order to achieve different cleaning and drying functions, traditional equipment usually has multiple workstations, plus cooling workstations, which makes the overall size of the equipment large, occupies a lot of space, and has high investment costs.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Reference Figure 1 A stainless steel drum washing and drying line adopts a linear four-station layout, consisting of outer drum washing station 1, inner drum washing station 2, drying station 3, and unloading station 4.

[0026] Above the four workstations, a clamping and lifting device 5, approximately 15m in length, is installed to facilitate the transport of stainless steel drums 6 to the corresponding workstations. The clamping and lifting device includes a crossbeam frame 7, with rack-equipped guide rails 8 on both sides. A translation platform 9 is mounted on each guide rail, and gears 10 corresponding to the racks are mounted on both sides of the translation platform. The gears 10 are connected to a drive motor, which drives the gears 10 to move the translation platform 9 along the racks (X-axis movement). A lifting device is installed on the translation platform, driven by a cylinder (Y-axis lifting). The lifting rod 11 of the lifting device passes through a bushing 12 on the translation platform and connects to the clamping device 13. The clamping device 13 is a pneumatic clamping structure (conventional structure).

[0027] A feeding roller conveyor 14 is installed at the outer drum cleaning station 1 to transport stainless steel drums into position. The feeding roller conveyor is a powered roller conveyor. The powered roller conveyor uses 304 stainless steel rollers and is driven by a servo motor. Positioning is achieved via a photoelectric switch (accuracy ±5mm).

[0028] Two sets of high-pressure water nozzles 15 (or multiple sets) are installed around the outer tub cleaning station. The surface of the outer tub is cleaned using the high-pressure water nozzles.

[0029] A stainless steel drum placement platform 16 is installed at the lower part of the inner drum cleaning station. A three-dimensional rotating nozzle device extending upwards is installed at the inner drum cleaning station. The three-dimensional rotating nozzle device includes a motor drive unit 17, an inner rod 18, an outer rod 19, and a water outlet device 20. The motor drive unit 17 is installed below the stainless steel drum placement platform 16 and includes a motor and a gearbox. The outer rod 19 is a hollow structure, fitted over the inner rod 18, and the outer rod 19 and inner rod 18 are coaxially arranged. The inner rod and outer rod extend upwards through the stainless steel drum placement platform 16. The lower end of the outer rod 19 is fixedly connected to the gearbox, and the inner rod 18 passes through the gearbox. The inner rod is connected to the motor output transmission via a transmission gear. The inner rod 18 is a hollow structure, with its water inlet located at the bottom. The upper end of the inner rod 18 is fixedly connected to the water outlet device 20, which rotates synchronously with the inner rod 18. The water outlet device 20 has a rotating nozzle seat 21 inside, which is equipped with bearings. The nozzle seat 21 has a nozzle 22. A water inlet 25 is located in the middle of the nozzle seat, and a cleaning channel 26 is located inside. An inner rod 18 is connected to the nozzle seat 21. A first bevel gear 23 is connected to the upper end of an outer rod 19, and the first bevel gear 23 is coaxial with the inner rod 18. A second bevel gear 24 is fixedly mounted on the nozzle seat 21. The first bevel gear 23 and the second bevel gear 24 mesh. As the nozzle seat rotates with the inner rod, the second bevel gear on the nozzle seat rotates around the first bevel gear. During operation, the stainless steel bucket is placed with its opening facing downwards.

[0030] Working logic: The motor drives the inner rod to rotate, which in turn drives the nozzle rotating seat to rotate. As the nozzle rotating seat rotates with the inner rod, the second bevel gear on the nozzle rotating seat rotates around the first bevel gear. This achieves the rotation of the nozzle rotating seat (compound motion).

[0031] There are two drying stations 3, arranged side by side, to improve drying efficiency. Each drying station 3 also has a stainless steel drum placement platform 16 (shared with the stainless steel drum placement platform of the inner drum cleaning station). The electric heating device uses an electric heating rod structure, with the electric heating rod 27 extending upwards through the stainless steel drum placement platform 16. During operation, the stainless steel drums are placed with their openings facing downwards.

[0032] A discharge roller conveyor 28 is installed at the unloading station to transport stainless steel drums outwards. The discharge roller conveyor is a powered roller conveyor. The powered roller conveyor uses 304 stainless steel rollers and is driven by a servo motor. Positioning is achieved via photoelectric switches (accuracy ±5mm). The entire process of handling / tilting is integrated (covering all station transfers).

[0033] The control system uses a Siemens S7-1200 PLC and a 10-inch Siemens touchscreen HMI. Low-voltage components are Schneider Electric series (DC24V control).

[0034] During cleaning, stainless steel drums are transported upside down to the loading roller conveyor using a forklift. High-pressure water nozzles clean the outer surface of the drums. Then, a clamping and lifting device transports the drums to the inner drum cleaning station and places them on a stainless steel drum placement platform. A three-dimensional rotating spray nozzle extends into the inside of the drum to clean it. After cleaning, the drums are transported to the drying station using the clamping and lifting device to dry the interior. Finally, after drying, the drums are transported to the unloading station for unloading.
