Description

Technical Field

[0001] This utility model belongs to the field of ice cylinder sealing technology. Specifically, it relates to an airbag-type ice cylinder sealing structure. Background Technology

[0002] In the brewing industry, ice tanks are a key piece of equipment, widely used in cooling, storage, and temperature control processes. Traditional ice tank sealing designs typically employ a flat-bottomed sealing ring that directly contacts the flat bottom edge of the ice tank body, relying on the downward pressure of the ice tank lid to achieve a seal. However, this sealing method has significant drawbacks and limitations.

[0003] First, due to the difficulty in precisely controlling the fit between components during installation, hot water steam easily leaks from the sealing joints during actual operation. This not only affects the cooling efficiency of the ice tank but also exacerbates humidity and temperature fluctuations within the brewery, adversely impacting the brewing environment. Second, under prolonged pressure and temperature changes, the flat-bottomed sealing ring is prone to slippage or detachment from the ice tank edge due to material aging, fatigue, or installation misalignment, significantly reducing its sealing effectiveness. Sealing failure not only leads to energy waste but can also contaminate brewing raw materials and products, affecting product quality. It also increases the difficulty of cleaning and maintenance in the brewery, causing a deterioration in the surrounding environment. Furthermore, once the sealing ring slips or is damaged, the repair process is often cumbersome and time-consuming. Disassembling the entire ice tank lid or surrounding structure to readjust or replace the sealing ring not only reduces production efficiency but also increases maintenance costs and labor intensity, impacting the overall operational efficiency of the brewery.

[0004] Given the various drawbacks of the traditional ice tank sealing design, it is necessary to develop a new sealing structure to solve problems such as poor sealing effect and difficulty in maintaining hygiene around the equipment. Utility Model Content

[0005] The purpose of this utility model is to provide an airbag-type ice cylinder sealing structure to address the aforementioned shortcomings. This solves the problem that existing ice cylinder seals using traditional flat-bottomed sealing rings are prone to slippage or detachment from the ice cylinder edge due to material aging, fatigue, or installation misalignment under prolonged pressure and temperature changes, significantly reducing the sealing effect. To achieve the above objective, this utility model provides the following technical solution: An airbag-type ice tank sealing structure includes an ice tank top cover and an ice tank wall; the ice tank top cover and the top of the ice tank wall are locked together to seal the ice tank opening; the top of the ice tank wall is provided with a first groove, and the bottom of the ice tank top cover is also provided with a second groove; after the ice tank top cover and the ice tank wall are locked together, the first groove and the second groove cooperate to form a sealing cavity, and an inflatable airbag is provided in the sealing cavity. Furthermore, a pressure relief hole is provided on the first groove on the wall of the ice tank, and the pressure relief hole is connected to the inside of the ice tank.

[0006] Furthermore, the ice tank top cover includes a cover plate and a rubber ring; the cover plate cooperates with the outer side of the ice tank wall to seal the ice tank opening; the rubber ring is fixed below the cover plate and is interference-fitted with the ice tank opening.

[0007] Furthermore, the rubber ring is provided with an annular groove, and after the rubber ring is connected to the ice cylinder opening, the annular groove communicates with the pressure relief hole.

[0008] Furthermore, the rubber ring is provided with several connecting holes, which connect the annular groove to the inside of the ice tank.

[0009] Furthermore, the inner side of the outer edge of the cover plate is provided with an internal thread structure; the outer side of the top of the ice cylinder wall is provided with an external thread structure, and the cover plate and the ice cylinder wall are engaged by the internal thread structure and the external thread mechanism.

[0010] Furthermore, the sealed cavity is provided with a through hole connecting to the outside of the ice tank; the inflatable airbag is provided with an air tube, which passes through the through hole and is connected to an air pump.

[0011] Furthermore, it also includes a pressure sensor; the pressure sensor is used to detect the pressure inside the sealed cavity.

[0012] Furthermore, it also includes a controller; the controller is electrically connected to the pressure sensor and the air pump, respectively.

[0013] Furthermore, the air pump is a mini air pump used to inflate and draw air from the airbag.

[0014] The beneficial effects of this utility model are: This utility model discloses an airbag-type ice cylinder sealing structure, which features a grooved sealing port where the top cover contacts the ice cylinder wall. Combined with an inflatable airbag sealing ring, the overall sealing effect is improved. The sealing performance can be further enhanced by dynamically adjusting the airbag pressure through the inflation port. Pressure is released through the pressure relief hole on the inner side of the ice cylinder wall, as well as the annular groove and connecting hole on the rubber ring. This not only prevents water and vapor leakage when the pressure inside the groove increases and is released to the outside, but also allows for internal pressure release after the airbag is inflated, preventing pressure buildup in the internal sealed gap from causing sealing failure.

[0018] Example: See attached Figures 1-3An airbag-type ice tank sealing structure includes an ice tank top cover 1 and an ice tank wall 2. The top cover 1 and the top of the ice tank wall 2 are locked together to seal the ice tank opening. The top of the ice tank wall 2 has a first groove, and the bottom of the ice tank top cover 1 also has a second groove. After the ice tank top cover 1 and the ice tank wall 2 are locked together, the first groove and the second groove cooperate to form a sealing cavity 3, and an inflatable airbag 4 is provided in the sealing cavity 3. As can be seen from the above structure, the sealing cavity 3 and the inflatable airbag 4 improve the sealing performance. Specifically, it includes a cylindrical ice tank body, with ice tank walls 2 around its perimeter. The ice tank walls 2 form an ice tank opening above the ice tank body, and the ice tank top cover 1 is fitted above the ice tank opening for sealing. Specifically, an annular first groove is provided at the top center of the ice tank wall 2, with the opening facing upwards. An annular second groove is provided at the corresponding position on the ice tank top cover 1 and the ice tank wall 2, with the opening facing downwards. When the ice tank top cover 1 and the ice tank wall 2 are connected, the openings of the first groove and the second groove are opposite to each other, forming a sealed cavity 3 for placing the inflatable airbag 4. By inflating the inflatable airbag 4, the sealing performance between the ice tank top cover 1 and the ice tank wall 2 is improved. The inflatable airbag 4 is placed in the sealed cavity 3 and is not easy to fall off. The air pressure of the inflatable airbag 4 can be adjusted to achieve the ideal sealing effect.

[0019] In this embodiment, the connection between the ice tank top cover 1 and the top of the ice tank wall 2 is a threaded connection. Specifically, the inner side of the outer edge of the cover plate of the ice tank top cover 1 has an internal thread structure, and the upper outer wall of the ice tank wall 2 has an external thread structure that mates with the internal thread on the cover plate. This can be understood as a threaded connection between a bottle cap and a bottle; that is, the ice tank wall 2 and the ice tank top cover 1 are fixed together by a threaded connection. In some embodiments, the ice tank top cover 1 and the ice tank wall can also be locked by a latch structure. The latch structure is a well-known prior art and will not be described in detail here.

[0020] In this embodiment, the ice tank top cover 1 includes a cover plate and a rubber ring; the cover plate cooperates with the outer side of the ice tank wall 2 to seal the ice tank opening; the rubber ring is fixed below the cover plate and is interference-fitted with the ice tank opening. As can be seen from the above structure, the ice tank top cover 1 is provided with a rubber ring, the diameter of which is larger than the diameter of the ice tank opening. When the ice tank top cover 1 is connected to the ice tank wall 2, the rubber ring and the ice tank wall 2 form an interference-fit ice tank opening, further improving the sealing performance. The rubber ring is made of a tough material such as rubber.

[0021] In this embodiment, a pressure relief hole 5 is provided on the first groove of the ice tank wall 2, and the pressure relief hole 5 communicates with the inside of the ice tank; the rubber ring is provided with an annular groove, and after the rubber ring is connected with the ice tank opening, the annular groove communicates with the pressure relief hole 5. As can be seen from the above structure, a pressure relief hole 5 is provided on the side of the first groove at the top of the ice tank wall 2 near the inside of the ice tank. The pressure relief hole 5 connects the first groove with the inside of the ice tank, preventing the rubber ring from blocking the pressure relief hole 5. The rubber ring is provided with an annular groove, the opening of which faces the horizontal direction, that is, towards the inside of the ice tank wall 2. When the ice tank top cover 1 is connected with the ice tank wall 2, the annular groove of the rubber ring is aligned with the pressure relief hole 5, that is, there is no need to consider the installation direction of the rubber ring, and it can be rotated to any direction with the threaded engagement. The setting of the annular groove ensures that the rubber ring will not block the pressure relief hole 5. At the same time, several connecting holes are evenly provided on the annular groove along the circumferential direction. The connecting holes connect the annular groove with the inside of the ice tank, that is, the first groove is connected to the inside of the ice tank through the annular groove. When the airbag 4 in the sealed cavity 3 is inflated and pressurized, water, vapor, etc., return to the inside of the ice tank through the pressure relief hole 5, the annular groove and the connecting hole, preventing leakage from the outside of the ice tank and causing the seal to fail.

[0022] In this embodiment, the sealed cavity 3 has a through hole 7 connecting to the outside of the ice tank; the inflatable airbag 4 has an air tube that passes through the through hole 7 and is connected to an air pump. As can be seen from the above structure, to facilitate the inflation or deflation of the inflatable airbag 4, a through hole 7 is provided on the side of the first groove near the outside of the ice tank, connecting the outside to the first groove. The air tube of the inflatable airbag 4 passes through the through hole 7 and is connected to an air pump. A mini air pump is sufficient for inflating and deflation of the inflatable airbag 4. The air tube and the through hole 7 can be sealed with a rubber sleeve. The size of the inflatable airbag 4 is controlled by the mini air pump, thereby controlling the sealing effect. When maintenance is required and the lid needs to be opened, the air can be released to prevent excessive pressure from causing the ice tank lid to pop open and cause safety issues.

[0023] In this embodiment, a pressure sensor is installed inside the sealed cavity 3, and a controller is electrically connected to the pressure sensor and the air pump. The pressure sensor feeds back the pressure signal to the controller, which then controls the air pump to inflate and deflate the airbag 4.

[0024] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
