Description

Technical Field

[0001] This utility model relates to the technical field of refrigeration equipment, and more specifically to a barrel-type refrigeration device. Background Technology

[0002] For the sake of sustainable development, oil drums, chemical drums, and other similar containers are recycled after their contents are depleted. Before recycling, the drums need to be cleaned of internal impurities. The conventional cleaning method is to rinse them with water. However, due to the large surface area of ​​the drum's inner wall, rinsing with water often requires manual assistance, which is not only inefficient but also leaves residues on the inner wall of the drum, considering that some raw materials are not water-soluble. Therefore, the cleaning effect cannot be guaranteed.

[0003] To address these issues, some researchers considered freezing the container with liquid nitrogen, causing impurities inside to solidify and become easier to remove later. However, the container floats in the liquid nitrogen, reducing the contact area between the container and the nitrogen and impacting freezing efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where the container floats up after being placed in liquid nitrogen due to buoyancy, thus reducing the contact area between the container and the liquid nitrogen and affecting the freezing efficiency.

[0005] To address the aforementioned problems, this utility model provides a barrel freezing device, comprising a freezing cylinder and a barrel gripping module. The upper side of the freezing cylinder has an opening for inserting a barrel, and liquid nitrogen is contained within the freezing cylinder. The barrel gripping module is used to move the barrel in and out of the freezing cylinder. At least two linear drive members are arranged circumferentially at the upper end of the freezing cylinder. Each linear drive member has a pressure rod facing the opening of the freezing cylinder, and the linear drive member is used to move the pressure rod to the opening of the freezing cylinder to press the barrel inside the freezing cylinder.

[0006] The above solution involves placing liquid nitrogen inside the freezing cylinder. When the grabbing assembly pulls the cylinder into the freezing cylinder, the linear drive unit drives the pressure rod to extend towards the opening of the freezing cylinder until it comes into contact with the upper side of the cylinder. At this point, the upward buoyancy force on the cylinder is offset by the pressure rod, and the cylinder can cool rapidly while maintaining a large contact area with the liquid nitrogen, effectively improving the cooling efficiency.

[0007] In an improved embodiment, the bucket-grabbing module includes a conveying component and grippers, the grippers being used to grasp the bucket body, and the conveying component acting on the grippers to drive the grippers to move laterally or vertically.

[0008] In an improved embodiment, the conveying assembly includes an X-axis drive slide rail arranged in the front-to-back direction, a Y-axis drive slide rail arranged in the left-to-right direction, and a Z-axis drive slide rail arranged in the up-down direction. The Y-axis drive slide rail is driven by the X-axis drive slide rail to move in the front-to-back direction, the Z-axis drive slide rail is driven by the Y-axis drive slide rail to move in the left-to-right direction, and the gripper is driven by the Z-axis drive slide rail to move in the up-down direction.

[0009] In an improved embodiment, the freezing cylinder is provided with a cylindrical limiting frame with its axis running vertically. The sidewalls of the limiting frame are grid-like, and the inner side of the limiting frame allows the container to enter. This allows the limiting frame to vertically guide containers of different sizes and specifications, preventing the containers from tipping over inside the freezing cylinder.

[0010] In an improved version, the limiting bracket is detachably connected to the freezing cylinder, so that limiting brackets with different inner diameters can be used according to the size specifications of the cylinder, further improving versatility.

[0011] In an improved embodiment, the inner diameter of the upper end of the limiting frame is larger than the inner diameter of the lower end, thereby guiding the barrel as it moves from top to bottom.

[0012] In an improved version, the linear drive component is a cylinder, which ensures stable and reliable operation. Attached Figure Description

[0021] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] Please see Figures 1-3 An embodiment of this utility model provides a barrel freezing device, including a freezing cylinder 1 and a barrel gripping module. The upper side of the freezing cylinder 1 is provided with an opening for the barrel to be placed in. Liquid nitrogen is provided inside the freezing cylinder 1. The barrel gripping module is used to drive the barrel in and out of the freezing cylinder 1. At least two linear drive members 11 are arranged circumferentially at the upper end of the freezing cylinder 1. The linear drive members 11 are provided with a pressure rod 12 facing the opening of the freezing cylinder 1. The linear drive members 11 are used to drive the pressure rod 12 to move to the opening of the freezing cylinder 1 to press the barrel inside the freezing cylinder 1.

[0023] The above solution involves placing liquid nitrogen inside the freezing cylinder 1. When the grabbing assembly pulls the barrel into the freezing cylinder 1, the linear drive 11 drives the pressure rod 12 to extend towards the opening of the freezing cylinder 1 until it comes into contact with the upper side of the barrel. At this point, the upward buoyancy of the barrel is offset by the pressure rod 12, and the barrel can be rapidly cooled while maintaining a large contact area with the liquid nitrogen, effectively improving the cooling efficiency.

[0024] In this embodiment, the bucket-grabbing module includes a conveying component 3 and a gripper 31. The gripper 31 is used to grab the bucket body, and the conveying component 3 acts on the gripper 31 to drive the gripper 31 to move horizontally or vertically.

[0025] More specifically, the conveying component 3 includes an X-axis drive slide rail 32 arranged in the front-to-back direction, a Y-axis drive slide rail 33 arranged in the left-to-right direction, and a Z-axis drive slide rail 34 arranged in the up-down direction. The Y-axis drive slide rail 33 is driven by the X-axis drive slide rail 32 to move in the front-to-back direction, the Z-axis drive slide rail 34 is driven by the Y-axis drive slide rail 33 to move in the left-to-right direction, and the gripper 31 is driven by the Z-axis drive slide rail 34 to move in the up-down direction.

[0026] As an improvement to this embodiment, the freezing cylinder 1 is provided with a cylindrical limiting frame 2 with its axis running vertically. The side wall of the limiting frame 2 is grid-like, and the inner side of the limiting frame 2 allows the barrel to enter. Thus, the limiting frame 2 can be used to vertically guide barrels of different sizes and specifications, preventing the barrel from tipping over inside the freezing cylinder 1.

[0027] Furthermore, the limiting bracket 2 is detachably connected to the freezing cylinder 1, allowing for the replacement of limiting brackets 2 with different inner diameters depending on the size and specifications of the cylinder, thus improving versatility. Regarding the specific form of the detachable connection between the limiting bracket 2 and the freezing cylinder 1, a slot can be provided at the bottom of the freezing cylinder 1, allowing the bottom of the limiting bracket 2 to engage with the slot; alternatively, mounting bolts can be provided on the inner wall of the freezing cylinder 1, enabling the connection of the limiting bracket 2.

[0028] Furthermore, the inner diameter of the upper end of the limiting frame 2 is larger than the inner diameter of the lower end, thus forming a conical structure inside the limiting frame 2 that is larger at the top and smaller at the bottom, which can guide the barrel when it moves from top to bottom.

[0029] In this embodiment, the linear drive 11 is preferably a cylinder, which is stable and reliable in operation.
