Description

Technical Field

[0001] The utility model relates to the technical field of granary closed pressure air-conditioning installation, in particular to a shallow circular silo split type closed pressure air-conditioning pipeline sealing structure. Background Art

[0002] During the installation of a split-type, sealed, pressurized air conditioner for a shallow silo, attention should be paid to the sealing of the internal pipes, evaporation box, and the area between the pipes and the wall. This is to facilitate regular aeration and sterilization, and to maintain heat preservation and storage. In the prior art, Chinese patent document CN221532182U discloses a grain silo ventilation and electrical sealing structure. This solution uses elastic rubber blocks and sealing blocks for sealing, which is a fixed method. However, the air conditioning pipes often need to exhaust or inlet air during use, causing the pipes to vibrate frequently. Furthermore, since the air temperature is not constant, the pipes themselves will also expand and contract with heat. This ultimately leads to poor sealing of the internal pipes, evaporation box, and the area between the pipes and the wall. This results in insufficient airtightness and poor insulation performance for the grain silo as a whole.

[0003] A split-type closed pressure-bearing air-conditioning pipe sealing structure for a shallow circular silo is now provided. This structure can provide a sealing structure for the air-conditioning pipes of existing granaries. It can effectively cope with the vibration and thermal contraction of the pipes during use. It can maintain the sealing effect of the internal pipes of the air-conditioning, the evaporation box, and the space between the pipes and the wall, prevent gas leakage, and is beneficial to the insulation inside the granary. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the existing technology, the utility model provides a split-type closed pressure-bearing air-conditioning pipe sealing structure for a shallow circular silo, which effectively solves the problems of poor sealing effects in positions such as internal pipes of the air conditioner, evaporation boxes, and between pipes and walls, and the overall air tightness of the silo is insufficient and the thermal insulation performance is poor.

[0005] The technical solution is to include an outer tube, an inner tube is inserted into the outer tube, and multiple annular airbags are arranged between the inner tube and the outer tube; multiple annular partitions are arranged on the inner wall of the outer tube, and annular protrusions are arranged on the outer wall of the inner tube, and the annular protrusions correspond to the partitions one by one. The partitions and the annular protrusions separate adjacent airbags, and the multiple airbags are connected to each other.

[0006] Furthermore, in order to enable the airbag to compress the inner tube inward and hold the pipe tightly when inflating, the inner tube and the annular protrusion thereon are made of rubber material.

[0007] Furthermore, in order to enable the outer cylinder to be fixed on the wall without shaking, a plurality of annular plates are provided on the outer side wall of the outer cylinder.

[0008] Furthermore, in order to reduce heat loss, the outer cylinder is made of rubber.

[0009] The utility model has an ingenious structure and can propose a sealing structure for the air-conditioning pipes of existing granaries. It can effectively cope with the vibration and thermal contraction of the pipes during use, maintain the sealing effect between the pipes and the wall, prevent gas leakage, and is beneficial to the insulation of the interior of the granary.

[0014] The specific implementation of the present invention is further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 4 The utility model includes an outer tube 1, an inner tube 2 is inserted into the outer tube 1, and a plurality of annular airbags 3 are arranged between the inner tube 2 and the outer tube 1; a plurality of annular partitions 4 are arranged on the inner wall of the outer tube 1, and an annular protrusion 5 is arranged on the outer wall of the inner tube 2, and the annular protrusion 5 corresponds to the partition 4 one by one. The partition 4 and the annular protrusion 5 separate the adjacent airbags 3, and the plurality of airbags 3 are connected to each other.

[0016] In order to enable the airbag 3 to compress the inner tube 2 inward and hold the pipe tightly when inflating, the inner tube 2 and the annular protrusion 5 thereon are made of rubber material.

[0017] In order to ensure that the outer cylinder 1 can be fixed on the wall without shaking, a plurality of annular plates 6 are provided on the outer side wall of the outer cylinder 1 .

[0018] In order to reduce heat loss, the outer cylinder 1 is made of rubber.

[0019] It is worth noting that in this solution, the outer wall of the outer tube 1 is close to the reserved hole on the wall, and a groove corresponding to the annular plate 6 is opened on the side wall of the reserved hole. The annular plate 6 on the outer side of the outer tube 1 is inserted into the inside of the wall, so that the outer tube 1 is fixed to the wall; the inner tube 2, the outer tube 1, the partition 4, etc. are made of rubber material, which can not only insulate heat, but also effectively resist leakage caused by pipeline ventilation vibration; the inner tube 2 and the outer wall of the pipeline are pasted together. Specifically, heat-resistant glue can be applied to achieve a sealing effect and fixation between the two. Of course, direct contact can also be used between the two. The rubber inner tube 2 can also achieve sealing and fixation under the pressure of the airbag 3.

[0020] During use, the outer tube 1 is installed on the reserved hole of the wall in the above manner, and then the inner tube 2 is fixed on the inner wall. Then the inner tube 2 is placed in the outer tube 1 and the airbag 3 is inflated. After the airbag 3 expands, it contracts inward against the inner tube 2 and presses the outer wall of the pipeline. Finally, the valve of the airbag 3 is closed.

[0021] During the ventilation process, the vibration generated by the pipeline is eliminated by the shock-absorbing structure composed of the airbag 3, inner tube 2 and outer tube 1, that is, this structure can eliminate the axial vibration and radial vibration of the pipeline with excellent effect; when the pipeline expands and contracts due to temperature changes, the airbag 3 can also force the inner tube 2 to stick to the pipeline at any time to ensure its sealing effect. At the same time, due to the poor thermal conductivity of rubber material, it is beneficial to improve the overall thermal insulation performance of the granary.

[0022] The utility model has an ingenious structure and can propose a sealing structure for the air-conditioning pipes of existing granaries. It can effectively cope with the vibration and thermal contraction of the pipes during use, maintain the sealing effect between the pipes and the wall, prevent gas leakage, and is beneficial to the insulation of the interior of the granary.
