[0020] The container cleaning device provided by this technical solution includes an internal cleaning mechanism and an external cleaning mechanism. The external cleaning mechanism is used to clean the outer wall of the container, and then the internal cleaning mechanism cleans the inner wall of the container. Because the inner wall of the container is in direct contact with food, the cleanliness requirements are higher. Cleaning the outer wall of the container first and then cleaning the inner wall of the container avoids the inner wall of the container being contaminated again during the cleaning of the outer wall, thereby making the cleaning of the container more thorough and ensuring that the cleanliness of the inner wall of the container meets the high requirements.

[0021] Furthermore, it also includes a water supply mechanism, which comprises: a water storage tank connected to both the external and internal cleaning mechanisms, the water storage tank having at least two inlets; a hot water source connected to one of the inlets for supplying hot water to the water storage tank; and a heating device for heating the liquid in the water storage tank. The water supply mechanism is also connected to a hot water source, which directly supplies hot water to the water storage tank, reducing the heating time and energy consumption of the heating device, providing sufficient hot water for the cleaning mechanism, and thus ensuring a more thorough cleaning of the containers.

[0022] Furthermore, it also includes a collection tank with an open top, positioned below the internal cleaning mechanism and connected to the first nozzle. The cleaning fluid from the internal cleaning mechanism is reused to clean the exterior of the container tank using the first cleaning component, providing preliminary cleaning and reducing waste of cleaning fluid, thus conserving resources.

[0023] Furthermore, it also includes a controller, which is electrically connected to the drying mechanism. The controller is used to control the upper air outlet and the lower air outlet to output air at different times. The separate air output from the upper and lower air outlets at different times is beneficial for the concentrated supply of air volume and the increase of air pressure, which helps to shorten the drying time of the containers and makes the containers dry more thoroughly.

[0035] As described in the background section, cleaning containers and cans is a crucial step in ensuring food hygiene and safety during food processing. High-temperature hot water is typically used for cleaning to better dissolve powdered food ingredients and other raw materials on the containers. However, current cleaning devices often lack sufficient hot water supply or require significant energy to maintain the set temperature. Insufficient hot water temperature leads to incomplete cleaning. Furthermore, current cleaning devices do not effectively differentiate between external and internal wall cleaning, or they may perform internal wall cleaning before external wall cleaning, resulting in the internal wall becoming contaminated again during external cleaning and failing to meet cleanliness requirements.

[0036] To address the aforementioned problems, this utility model provides a container cleaning device, including a cleaning mechanism comprising an external cleaning mechanism and an internal cleaning mechanism. The external cleaning mechanism first cleans the outer wall of the container, and then the internal cleaning mechanism cleans the inner wall of the container, thus preventing the inner wall of the container from being contaminated again during the cleaning process of the outer wall and ensuring that the cleaning degree of the inner wall of the container meets the requirements.

[0037] The container cleaning device provided in this embodiment of the utility model has a water supply mechanism that, in addition to using a heating device to heat the liquid in the water storage tank, also has a hot water source connected to the water storage tank for adding hot water into the water storage tank. The heating device heats the hot water itself to a higher set temperature, which requires less energy and has a shorter heating time. It can continuously provide hot water at the set temperature to the cleaning mechanism so as to clean the container tank more thoroughly.

[0038] To make the above-mentioned objectives, features and beneficial effects of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0039] Figure 1 This is a schematic diagram of the structure of the container in one embodiment of the present invention; Figure 2 This is a modular top view of a container cleaning device according to an embodiment of the present invention; Figure 3 This is a schematic diagram of the system structure of the container cleaning device in one embodiment of this utility model.

[0040] Reference Figures 1 to 3The container cleaning device 10 includes: a frame (not shown), on which a conveying mechanism 100 is provided for conveying containers 11 to be cleaned; a cleaning mechanism 200, which is provided on the frame and includes an external cleaning mechanism and an internal cleaning mechanism, which are arranged sequentially along the conveying direction of the containers 11, and the containers 11 are cleaned by the external cleaning mechanism and then by the internal cleaning mechanism; and a drying mechanism 300, which is provided on the frame and located downstream of the cleaning mechanism 200, and is used to dry the cleaned containers 11.

[0041] refer to Figure 1 In this embodiment, the container 11 includes a container body 12, a top opening 13 at the top of the container body 12, and a bottom opening 13 at the bottom of the container body 12.

[0042] In this embodiment, the diameter of the top opening 12 is larger than the diameter of the bottom opening 13.

[0043] In this embodiment, the top opening 12 has a cover (not shown). Before cleaning the container 11, the staff opens the cover to allow for subsequent cleaning of the inside of the container 11.

[0044] In this embodiment, the conveying mechanism 100 includes a conveying track 101 and a conveying support 102. The conveying support 102 is placed on the conveying track 101 and is used to place the container 11. The conveying track 101 is used to move the conveying support 102 and the container 11.

[0045] In this embodiment, the conveying bracket 102 is used to fix the container 11. After the container 11 is fixed on the conveying bracket 102, the conveying bracket 102 is placed on the conveying track 101, and the conveying track 101 conveys the conveying bracket 102 and the container 11.

[0046] In some embodiments, the conveying track 101 is generally arranged in a U-shape or a straight line.

[0047] In this embodiment, the conveyor track 101 is U-shaped, including two opposing straight segments and a connecting segment connecting the straight segments. The U-shaped arrangement can save the overall layout space of the container cleaning device.

[0048] In this embodiment, the cleaning mechanism 200 and the drying mechanism 300 are respectively arranged on the opposite straight sections of the U-shaped conveyor track, which can make the most of the space.

[0049] Continue to refer to Figure 3 The container cleaning device 10 further includes a water supply mechanism 400, which includes: a water storage tank 410 connected to the external cleaning mechanism and the internal cleaning mechanism, the water storage tank 410 including at least two water inlets; a hot water source 411 connected to one of the water inlets for supplying hot water to the water storage tank 410; and a heating device 420 for heating the liquid in the water storage tank 410.

[0050] In some embodiments, the water tank 410 stores liquid for cleaning the container tank 11, including water or cleaning solution mixed with cleaning agent.

[0051] In this embodiment, the water supply mechanism 400 provides high-temperature hot water to the cleaning container 11. The temperature range of the hot water is 70℃~80℃. The high-temperature hot water is more conducive to dissolving food raw materials such as powder in the container 11, making the cleaning of the container 11 more thorough.

[0052] The water storage tank 410 includes at least two water inlets. In this embodiment, the water storage tank 410 includes two water inlets. One water inlet is connected to a hot water source 411, which can directly fill the water storage tank 410 with hot water. The other water inlet can be connected to a cold water source 412, etc.

[0053] In this embodiment, in addition to heating the liquid in the water storage tank 410 using the heating device 420, hot water is also injected into the water storage tank 410 through the hot water source 411 to directly heat the hot water to the set temperature. This is more energy-efficient than heating cold water and takes less time to heat to the set temperature, ensuring a continuous supply of hot water during the cleaning process.

[0054] In some embodiments, the hot water source 411 can be a device that generates or stores hot water in other production workshops, and can be linked with other production workshops to make full use of the hot water generated in other production workshops, which is conducive to saving energy and reducing costs.

[0055] In this embodiment, the heating device 420 is a steam heating device, which includes a steam coil installed in the water storage tank 410. The steam source 421 supplies steam to the steam coil to heat the liquid in the water storage tank 410.

[0056] Reference Figure 3 and Figure 4The external cleaning mechanism includes a first cleaning component 210, which includes: a first vertical pipe 211 symmetrically arranged on both sides of the conveying track 101; and a plurality of first nozzles 212 arranged on the first vertical pipe 211, which are interconnected with each other.

[0057] In this embodiment, the water supply mechanism 400 is connected to the first nozzle 212 through the first vertical pipe 211.

[0058] In this embodiment, the first cleaning component 210 further includes a first horizontal pipe 213, which is disposed on the conveying track 101 and connected to a first vertical pipe 211 disposed opposite to it. The first horizontal pipe 213 is perpendicular to the conveying direction of the conveying track 101.

[0059] In this embodiment, no first nozzle 212 is provided on the first horizontal pipe 213; in other embodiments, multiple first nozzles 212 may be provided on the first horizontal pipe 213.

[0060] In this embodiment, the first vertical pipe 211 and the first horizontal pipe 213 are arranged in the form of a door frame above the conveyor track 101. The first vertical pipe 211 is perpendicular to the plane where the conveyor track 101 is located, and the first horizontal pipe 314 is arranged above the conveyor track 101. When cleaning the container 11, the conveyor track 101 drives the container 11 to pass through the door frame formed by the first vertical pipe 211 and the first horizontal pipe 213.

[0061] In this embodiment, the first cleaning component 210 is used for the first cleaning process of the outer wall of the container 11. Multiple first nozzles 212 are arranged from top to bottom on the first vertical pipe 211. When the container 11 passes through the first cleaning component 210, the cleaning liquid sprayed by the first nozzles 212 can cover the container 11 from top to bottom, reducing the cleaning dead corners of the container 11 and making the cleaning of the container 11 more thorough.

[0062] Continue to refer to Figure 3 and Figure 4The external cleaning mechanism further includes a second cleaning component 220, which is located downstream of the first cleaning component 210. The second cleaning component 220 includes: a second vertical pipe 221, which is symmetrically arranged on both sides of the conveyor track 101; a second horizontal pipe 222, which is arranged above the conveyor track 101; and a plurality of second nozzles 223, which are respectively arranged on the second vertical pipe 221 and the second horizontal pipe 222. The plurality of second nozzles 223, the first vertical pipe 221, and the second horizontal pipe 222 are interconnected.

[0063] In this embodiment, the water supply mechanism 400 and the second nozzle 223 are connected through the second vertical pipe 221 and the second horizontal pipe 222.

[0064] In this embodiment, the arrangement of the second vertical pipe 221 and the second horizontal pipe 222 is the same as that of the first vertical pipe 211 and the first horizontal pipe 213, and will not be described again here.

[0065] In this embodiment, the second cleaning component 220 is used for the second step of cleaning the outer wall of the container tank 11. The container tank 11 undergoes two cleaning steps to clean its outer wall, resulting in a more thorough cleaning and ensuring hygiene and safety during the production process.

[0066] In other embodiments, the external cleaning mechanism may also be equipped with more cleaning components to provide more than two cleaning processes for the exterior of the container.

[0067] refer to Figure 3 The internal cleaning mechanism includes a third cleaning component 230, which includes a third pipe 231 and a third nozzle 232. The third pipe 231 and the third nozzle 232 are interconnected, and the third nozzle 232 is vertically and flexibly mounted on the top of the frame.

[0068] In this embodiment, the third cleaning component 230 is located downstream of the second cleaning component 220. The third cleaning component 230 is used to clean the interior of the container 11. The container 11 first passes through the first cleaning component 210, where the first nozzle 212 performs a first cleaning of the outer wall of the container 11. Then it passes through the second cleaning component 220, where the second nozzle 223 performs a second cleaning of the outer wall of the container 11. Finally, it reaches the third cleaning component 230, where the third nozzle 232 cleans the interior of the container 11. Cleaning the outer wall of the container 11 first, followed by the inner wall, is crucial because the inner wall directly contacts food and requires higher hygiene standards. Cleaning the inner wall later prevents further contamination after initial cleaning, ensuring a more thorough cleaning of the container 11.

[0069] In some embodiments, the number of the third nozzles 232 may be one or more.

[0070] In this embodiment, the third nozzle 232 can move up and down in a direction perpendicular to the ground via a lifting mechanism. When the container 11 passes the third cleaning assembly 230, the third nozzle 232 can extend into the container 11 via the lifting mechanism to further clean the dirt on the inner wall of the container 11 and improve the cleanliness of the inner wall of the container 11.

[0071] In this embodiment, the water supply mechanism 400 and the third nozzle 232 are connected through the third pipeline 231.

[0072] In this embodiment, the third cleaning component 230 further includes a baffle plate 233, which is disposed above the third nozzle 232 and moves up and down with the third nozzle 232.

[0073] In this embodiment, the baffle plate 233 rises and falls together with the third nozzle 232. The baffle plate 233 is used to prevent the cleaning liquid from splashing everywhere when the third nozzle 232 cleans the inner wall of the container tank 11.

[0074] In this embodiment, the container cleaning device 10 further includes a controller (not shown), which is electrically connected to the external cleaning mechanism and the internal cleaning mechanism, and is used to control the start and end of each cleaning process.

[0075] Continue to refer to Figure 3 The container cleaning device 10 further includes a bottom cleaning mechanism, which includes a fourth pipe 241 and a fourth nozzle 242. The fourth pipe 241 and the fourth nozzle 242 are interconnected. The fourth nozzle 242 is disposed at the bottom of the frame and is disposed opposite to the third nozzle 232.

[0076] In this embodiment, the water supply mechanism 400 and the fourth nozzle 242 are connected through the fourth pipeline 241.

[0077] In this embodiment, the bottom cleaning mechanism is used to clean the bottom of the container tank 11. When the container tank 11 passes the bottom cleaning mechanism, the fourth nozzle 242 faces the bottom opening 14 of the container tank 11. Usually, a bottom valve is installed at the bottom opening of the container tank 11. By setting the bottom cleaning mechanism, the bottom valve can be cleaned in a focused manner, reducing the cleaning dead corners of the container tank 11.

[0078] In this embodiment, the container cleaning device 10 further includes a liquid collection tank 250, the top of which is open, and the liquid collection tank 250 is disposed below the internal cleaning mechanism. The liquid collection tank 250 is connected to the first nozzle 212.

[0079] In this embodiment, the collection tank 250 is used to collect the cleaning fluid after cleaning by the internal cleaning mechanism, and then the first cleaning component 210 is used to perform the first cleaning on the outside of the container tank 11. The cleaning fluid can be reused, which can reduce the use of cleaning fluid and help reduce cleaning costs.

[0080] Continue to refer to Figure 3 The drying mechanism 300 includes a drying fan 310 and an air outlet. The drying fan 310 is connected to the air outlet. The air outlet includes an upper air outlet 320 and a lower air outlet 330. The upper air outlet 320 and the lower air outlet 330 are arranged opposite to each other. The upper air outlet 320 faces the top opening 13 of the container 11 to be dried, and the lower air outlet 330 faces the bottom opening 14 of the container 11 to be dried.

[0081] In this embodiment, the drying fan 310 provides hot air to the air outlet.

[0082] In some embodiments, the number of upper air outlets 320 may be one or more, and the number of lower air outlets 330 may be one or more.

[0083] In this embodiment, the airflow from the upper air outlet 320 passes through the container 11 from top to bottom, and the airflow from the lower air outlet 330 passes through the container 11 from bottom to top.

[0084] In this embodiment, since the diameter of the top opening of the container 11 is larger than the diameter of the bottom opening of the container 11, when the airflow enters the top opening 13 or the bottom opening 14 of the container 11 from the air, and when the airflow flows from the top opening 13 to the bottom opening 14 inside the container 11, the airflow velocity increases and the fluid pressure decreases when passing through the narrowed flow cross section, forming a Venturi effect, which can dry the container 11 more quickly.

[0085] In this embodiment, the drying mechanism 300 further includes an air supply duct, which includes a main air supply duct 340, a first branch 341, and a second branch 342. The main air supply duct 340 is connected to the first branch 341 and the second branch 342. The first branch 341 is connected to the upper air outlet 320, and the second branch 342 is connected to the lower air outlet 330.

[0086] In this embodiment, the controller is electrically connected to the drying mechanism 300, and the controller is used to control the upper air outlet 320 and the lower air outlet 330 to blow air at different times.

[0087] In this embodiment, the controller controls the upper air outlet 320 and the lower air outlet 330 to blow air separately at different times. This can concentrate the air volume to the upper air outlet 320 or the lower air outlet 330. With the same power of the drying fan 310, the upper air outlet 320 and the lower air outlet 330 blow air separately, resulting in a larger air volume and stronger air pressure. This is beneficial for shortening the drying time of the container 11, accelerating the drying process, and making the drying more thorough.

[0088] Continue to refer to Figure 3 The container cleaning device 10 further includes a purging mechanism 500, which is located downstream of the cleaning mechanism 200 and upstream of the drying mechanism 300.

[0089] In this embodiment, after the container 11 is cleaned, it first passes through the blowing mechanism 500, which initially blows away the water droplets on the container 11, and then passes through the drying mechanism 300 for further drying, which can improve the drying efficiency of the container 11.

[0090] The purging mechanism 500 includes a purging fan 510 and a blower. The purging fan 510 is connected to the blower. The blower includes a side blower 520 and a bottom blower 530. The side blowers 520 are symmetrically arranged on both sides of the conveying track 101 and face the outer wall of the container tank 11. The bottom blower 530 is arranged at the bottom of the frame and faces the bottom opening 14 of the container tank 11.

[0091] In this embodiment, there are multiple side air outlets 520. The purging mechanism 500 includes a first air supply pipe 521 vertically arranged on both sides of the conveying track 101. The side air outlets 520 are arranged along the first air supply pipe 521. When the container 11 passes through the purging mechanism 500, the side air outlets 520 face the outer wall of the container 11.

[0092] In this embodiment, there are multiple bottom air outlets 530. The purging mechanism 500 includes a second air supply pipe 531 mounted on the frame. The bottom air outlets 530 are mounted on the second air supply pipe 531. When the container 11 passes through the purging mechanism 500, the bottom air outlets 530 face the bottom opening 14 of the container 11.

[0093] In this embodiment, the purging mechanism further includes a rotary table (not shown), which is used to drive the container tank 11 to rotate when the purging mechanism is working.

[0094] In this embodiment, when the purging mechanism is working, the container 11 rotates simultaneously so that the purging mechanism blows air onto the container 11 from all directions.

[0095] While the present invention has been disclosed above, it is not limited thereto.
