Description

Technical Field

[0001] The utility model relates to the technical field of sealed tube sheets, in particular to an anti-corrosion double-sealed tube sheet for a dry evaporator. Background Art

[0002] The anti-corrosion double-sealed tube sheet of the dry evaporator is mainly used to prevent leakage or contamination between the internal medium of the evaporator (usually liquid refrigerant) and the external environment. In the dry evaporator, the refrigerant flows through the pipeline, and the anti-corrosion double-sealed tube sheet serves as one of the channels for the refrigerant to flow. The tube sheet is usually made of corrosion-resistant materials to ensure long-term stable operation and prevent the external environment from contaminating the refrigerant. The double-seal design can improve the sealing performance, reduce the risk of leakage, and ensure the safety and reliability of the system.

[0003] However, after long-term use, the anti-corrosion double-sealed tube sheet of the existing dry evaporator is prone to adsorb more impurities on the surface, which is not convenient for quickly removing the impurities adsorbed on the surface. When there are too many impurities, it is easy to affect the service life of the anti-corrosion double-sealed tube sheet of the dry evaporator.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an anti-corrosion double-sealed tube sheet for a dry evaporator is proposed. Utility Model Content

[0005] The utility model aims to provide an anti-corrosion double-sealed tube sheet for a dry evaporator, so as to solve the problem of removing adsorbed impurities proposed in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an anti-corrosion double-sealed tube sheet for a dry evaporator, comprising a tube sheet body, an array of through holes is arranged on the tube sheet body, a limiting hole is arranged on the tube sheet body, a rotating shaft is movably arranged inside the limiting hole, a support plate is fixedly connected to the top end of the rotating shaft, a cleaning plate is fixedly installed on the support plate, and a rotating handle is fixedly installed on the top of the support plate.

[0007] Furthermore, the rotating handle is located in the middle of the support plate.

[0008] Furthermore, the support plate is made of iron material.

[0009] Furthermore, a magnetic attraction plate is fixedly mounted on the tube plate body, and the magnetic attraction plate is located below the support plate.

[0010] Furthermore, an annular groove is arranged around the tube sheet body.

[0011] Furthermore, a rubber airbag is fixedly installed inside the annular groove.

[0012] Furthermore, an inflation head is provided on the tube sheet body, and the inflation head is connected to the rubber airbag.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model provides a cleaning plate. When there are too many impurities adsorbed on the tube sheet body and the impurities need to be removed, the rotating handle is manually rotated, and then the rotating shaft is rotated through the limiting hole. When the rotating shaft rotates, the supporting plate is driven to move. When the supporting plate moves, the cleaning plate is driven to move. When the cleaning plate moves, it contacts the surface of the tube sheet body, and then the impurities adsorbed on the surface of the tube sheet body can be removed, thereby achieving the purpose of improving cleanliness and effectively extending the service life of the anti-corrosion double-sealed tube sheet of the dry evaporator.

[0015] 2. The utility model is provided with a rubber airbag. After the anti-corrosion double-sealed tube sheet of the dry evaporator is installed, it is connected to an external air pump through an inflation head. The air pump generates air pressure when it works. After the air pressure enters the interior of the rubber airbag, the volume of the rubber airbag will expand, thereby improving the sealing of the installation location of the tube sheet body, achieving the purpose of improving the sealing, and thus improving the practicality of the anti-corrosion double-sealed tube sheet of the dry evaporator.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] like Figure 1 - Figure 3 As shown, an anti-corrosion double-sealed tube sheet for a dry evaporator comprises a tube sheet body 1, on which a through hole 2 is arranged in an array, and a limit hole 3 is arranged on the tube sheet body 1, and a rotating shaft 4 is arranged for the internal limit movement of the limit hole 3, and a support plate 5 is fixedly connected to the top of the rotating shaft 4, and a cleaning plate 6 is fixedly installed on the support plate 5, and a rotating handle 7 is fixedly installed on the top of the support plate 5. When the anti-corrosion double-sealed tube sheet for a dry evaporator is used, the tube sheet body 1 is installed on the dry evaporator. The tube sheet body 1 is mainly used to prevent the corrosive medium from eroding and damaging the tube sheet. The tube sheet body 1 comprises an inner seal and an outer seal. The inner seal is used for the side in direct contact with the medium, and the outer seal is used for the side in contact with the ambient air. The inner seal can be made of corrosion-resistant materials, such as stainless steel, alloy, etc., to resist the medium. The outer seal is usually made of high temperature resistant and corrosion resistant materials, such as special rubber, polytetrafluoroethylene (PTFE), etc., to prevent the external environment from corroding the tube sheet. The anti-corrosion double-sealed tube sheet can effectively improve the corrosion resistance of the dry evaporator, reduce maintenance and replacement costs, and ensure the long-term stable operation of the equipment. When there are too many impurities adsorbed on the tube sheet body 1, the impurities are removed by manually rotating the rotating handle 7, and then the rotating shaft 4 is rotated through the limiting hole 3. When the rotating shaft 4 rotates, it will drive the support plate 5 to move. When the support plate 5 moves, it will drive the cleaning plate 6 to move. When the cleaning plate 6 moves, it contacts the surface of the tube sheet body 1, and then the impurities adsorbed on the surface of the tube sheet body 1 can be removed, thereby achieving the purpose of improving the cleanliness of the anti-corrosion double-sealed tube sheet of the dry evaporator.

[0024] Furthermore, the rotating handle 7 is located in the middle of the support plate 5 , and the support plate 5 can be easily rotated by rotating the handle 7 .

[0025] Furthermore, the support plate 5 is made of iron material, and a magnetic plate 8 is fixedly installed on the tube plate body 1, and the magnetic plate 8 is located below the support plate 5. After the support plate 5 contacts the magnetic plate 8, the position of the support plate 5 will be limited, and then the position of the cleaning plate 6 will be limited.

[0026] Embodiment 2

[0027] like Figure 1 and Figure 4 As shown, the utility model proposes an anti-corrosion double-sealed tube sheet for a dry evaporator. Compared with the first embodiment, as another implementation of the utility model, an annular groove 9 is arranged around the tube sheet body 1, and the tube sheet body 1 provides an installation space for the annular groove 9.

[0028] Furthermore, a rubber airbag 10 is fixedly installed inside the annular groove 9 , and the annular groove 9 provides an installation space for the rubber airbag 10 .

[0029] Furthermore, an air charging head 11 is provided on the tube sheet body 1, and the air charging head 11 is communicated with the rubber airbag 10. After the anti-corrosion double-sealed tube sheet of the dry evaporator is installed, it is connected to an external air pump through the air charging head 11. The air pump generates air pressure when it works. After the air pressure enters the interior of the rubber airbag 10, the volume of the rubber airbag 10 will expand, thereby improving the sealing of the installation location of the tube sheet body 1, achieving the purpose of improving the sealing, and thus improving the practicality of the anti-corrosion double-sealed tube sheet of the dry evaporator.

[0030] Working principle: When using the anti-corrosion double-sealed tube sheet of the dry evaporator, first, install the tube sheet body 1 on the dry evaporator. The tube sheet body 1 is mainly used to prevent the corrosive medium from eroding and damaging the tube sheet. The tube sheet body 1 includes an inner seal and an outer seal. The inner seal is used for the side in direct contact with the medium, and the outer seal is used for the side in contact with the ambient air. The inner seal can be made of corrosion-resistant materials, such as stainless steel, alloy, etc., to resist the corrosion of the medium, while the outer seal is usually made of high temperature resistant and corrosion-resistant materials, such as special rubber, polytetrafluoroethylene, etc. Ethylene (PTFE), etc., to prevent the external environment from corroding the tube sheet. The use of anti-corrosion double-sealed tube sheets can effectively improve the corrosion resistance of the dry evaporator, reduce maintenance and replacement costs, and ensure the long-term stable operation of the equipment. When there are too many impurities adsorbed on the tube sheet body 1, the impurities are removed by manually rotating the rotating handle 7, and then the rotating shaft 4 is rotated through the limiting hole 3. When the rotating shaft 4 rotates, it will drive the support plate 5 to move. When the support plate 5 moves, it will drive the cleaning plate 6 to move. When the cleaning plate 6 moves, it contacts the surface of the tube sheet body 1, and then the impurities adsorbed on the surface of the tube sheet body 1 can be removed.

[0031] Finally, after the anti-corrosion double-sealed tube sheet of the dry evaporator is installed, it is connected to an external air pump through the inflation head 11. The air pump generates air pressure when it works. After the air pressure enters the interior of the rubber airbag 10, the volume of the rubber airbag 10 will expand, thereby improving the sealing of the installation location of the tube sheet body 1, achieving the purpose of improving the sealing, and thus improving the practicality of the anti-corrosion double-sealed tube sheet of the dry evaporator.

[0032] This is the working principle of the anti-corrosion double-sealed tube sheet of this dry evaporator.
