Description

Technical Field

[0001] This utility model relates to the field of glass-lined reactor technology, and in particular to a heat-fitted integrated sight glass for a glass-lined reactor. Background Technology

[0002] Glass-lined equipment allows for observation of the reaction and changes of materials inside the vessel through a sight glass. Currently, such as Figure 4 As shown, the existing glass-lined reactor sight glass includes an upper sight glass cover, a lower sight glass cover, and the sight glass itself. The upper and lower sight glass covers clamp the sight glass and are connected by screws to form a sight glass assembly. When the sight glass needs to be replaced, the entire sight glass assembly must be disassembled first, and then the upper and lower sight glass covers must be removed before the sight glass can be taken off for replacement. Furthermore, additional sealant is required to seal the upper and lower sight glass covers and the sight glass, making the process cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0003] The purpose of this utility model is to provide a heat-fitted integrated sight glass for glass-lined reactors, so as to achieve quick sight glass replacement, simple operation, time and labor saving, and cost saving.

[0004] The integrated sight glass of this utility model for a glass-lined reactor includes a sight glass cover and a sight glass. The sight glass is heat-fitted onto the sight glass cover. The sight glass cover has a sight glass slot that matches the shape of the sight glass. 4-8 eye bolts are evenly distributed on the sight glass cover. A handle is provided on one side wall of the sight glass cover, and a connecting plate 13 is provided on the other side wall. The connecting plate 13 is connected to the glass-lined reactor 4 through a connecting hole and a cotter pin. After the sight glass slot expands by 20μm-30μm, the sight glass 2 is heat-fitted onto it.

[0005] Furthermore, the pressure cap on the sight glass is heated to 250℃-350℃, the sight glass slot expands by 20μm-30μm, and the sight glass is heat-insulated into the sight glass slot of the pressure cap on the sight glass.

[0006] Furthermore, the other side of the sight glass cover is connected to the sight glass transition ring of the glass-lined reactor via a connecting plate.

[0007] Furthermore, a reactor gasket is provided between the sight glass transition ring and the glass-lined reactor, and the sight glass transition ring is connected to the glass-lined reactor by hexagonal screws and nuts.

[0008] Furthermore, a limit stop is provided at the bottom of the sight glass transition ring, and the limit stop is located directly below the connecting plate.

[0009] Furthermore, the top of the handle is provided with an outer edge chamfer, and the outer edge chamfer is R3.

[0010] The heat-fitted integrated sight glass for the glass-lined reactor provided by this utility model has the following beneficial effects:

[0011] 1. The sight glass of this utility model is heat-fitted onto the upper cover of the sight glass. The sight glass and the upper cover of the sight glass are an integral structure, eliminating the need for screw assembly and allowing for quick installation.

[0012] 2. This utility model uses an iron rod or steel bar inserted into the eye bolt. By loosening the eye bolt, the sight glass can be opened. Opening the cotter pin allows for quick removal and replacement of the sight glass.

[0013] 3. No additional sealant or other sealant is required between the sight glass and the pressure cap on the sight glass of this utility model, which allows for quick replacement of the sight glass and saves costs.

[0014] Therefore, this utility model has the positive effects of enabling quick replacement of sight glasses, simple operation, saving time and effort, and saving costs. Attached Figure Description

[0022] like Figure 1As shown, the integrated sight glass of the glass-lined reactor provided by this utility model includes a sight glass upper cover 1 and a sight glass 2. The sight glass 2 is heat-fitted onto the sight glass upper cover 1. The sight glass upper cover 1 is provided with a sight glass slot that matches the shape of the sight glass 2. 4-8 eye bolts 11 are evenly arranged on the sight glass upper cover 1. A handle 12 is provided on one side wall of the sight glass upper cover 1, and a connecting plate 13 is provided on the other side wall of the sight glass upper cover 1. The connecting plate 13 is connected to the glass-lined reactor 4 through a connecting hole and a cotter pin. After the sight glass slot expands by 20μm-30μm, the sight glass 2 is heat-fitted onto it.

[0023] like Figure 2-3 As shown, in use, this invention involves first heating the upper cover 1 of the sight glass. After the sight glass slot expands by 20μm-30μm, the sight glass 2 is then heat-fitted onto the upper cover 1, making the sight glass 2 and the upper cover 1 an integral structure. Next, the upper cover 1 is connected to the glass-lined reactor 4 via the connecting plate 13. Tightening the lifting eye screw 11 allows the upper cover 1 and the sight glass 2 to be installed on the glass-lined reactor 4, eliminating the need for screw assembly and enabling quick installation. Finally, when it is necessary to remove the sight glass 2, an iron rod or rebar is inserted into the lifting eye screw 11, the screw is loosened, and the cotter pin is opened, allowing for quick removal of the sight glass 2. Furthermore, no additional sealant is required between the sight glass 2 and the upper cover 1, enabling quick sight glass replacement. The operation is simple, time-saving, labor-saving, and cost-effective.

[0024] The aforementioned sight glass upper cover 1 is heated to 250℃-350℃, causing the sight glass slot to expand by 20μm-30μm. The sight glass 2 is then heat-fitted into the sight glass slot of the sight glass upper cover 1. When the sight glass upper cover 1 cools to room temperature, the sight glass 2 is still heat-fitted into the sight glass slot of the sight glass upper cover 1. The sight glass 2 and the sight glass upper cover 1 form an integral structure, eliminating the need for screw assembly. This allows for quick installation, saving time, effort, and costs.

[0025] The other side of the aforementioned sight glass cover 1 is connected to the sight glass transition ring 3 of the glass-lined reactor via a connecting plate 13. Since the existing glass-lined reactor sight glass is installed on the glass-lined reactor 4 via the sight glass transition ring 3, the sight glass cover 1 of this invention can be directly connected to the existing glass-lined reactor sight glass transition ring 3 via the connecting hole and cotter pin of the connecting plate 13 for replacing the sight glass.

[0026] A reactor gasket 33 is provided between the sight glass transition ring 3 and the glass-lined reactor 4. The sight glass transition ring 3 is connected to the glass-lined reactor by an internal hexagon screw 31 and a nut 32. Since the existing glass-lined reactor sight glass is installed on the glass-lined reactor 4 through the sight glass transition ring 3, the reactor gasket 33 can enhance the connection between the sight glass transition ring 3 and the glass-lined reactor 4. The sight glass cover 1 and sight glass 2 of this utility model can be directly installed on the existing glass-lined reactor sight glass transition ring 3, making sight glass replacement convenient, time-saving, and labor-saving.

[0027] The bottom of the aforementioned sight glass transition ring 3 is provided with a limit stop 34, and the limit stop 34 is located directly below the connecting plate 13. The limit stop 34 is used for positioning to facilitate the replacement of the sight glass.

[0028] The handle 12 described above is provided with an outer edge chamfer 14, which is R3. The outer edge chamfer 14 facilitates the use of the handle 12 to quickly open the pressure cover 1 on the sight glass and replace the sight glass 2.

[0029] The technical solution of this utility model is not limited to the scope of the embodiments of this utility model, and the technical contents not described in detail in this utility model are all known technologies.
