Description

Technical Field

[0001] The present application relates to the technical field of sulfur preparation, and in particular to an output pipe of a molten sulfur kettle. Background Art

[0002] In the desulfurization process of the coking plant, sulfur-containing gas will produce sulfur foam after wet desulfurization treatment. These sulfur foams are rich in tiny particles of elemental sulfur. The sulfur melting kettle uses steam or other heat sources to heat the sulfur foam. When heated to a certain temperature (such as 70~80℃), the sulfur foam begins to stratify. The upper layer is a clear liquid, which is mainly composed of desulfurization liquid and other non-sulfur components; the lower layer is sulfur paste, which is mainly composed of aggregated and enlarged elemental sulfur particles. The molten sulfur paste is discharged from the sulfur melting kettle through the sulfur discharge valve and becomes block solid sulfur after cooling; the upper clear liquid returns to the solution circulation tank, is mixed with other desulfurization liquids and then recycled.

[0003] However, the clear liquid coming out of the molten sulfur kettle will be mixed with sulfur. The sulfur content in the clear liquid can be adjusted by adjusting the sulfur discharge valve and the valve on the clear liquid pipeline. However, since the operator cannot observe the purity of the clear liquid in the clear liquid pipeline, he can only make adjustments based on experience. When the clear liquid contains a lot of sulfur, the sulfur accumulates in the circulation tank, causing the circulation tank to be blocked. When the clear liquid contains less sulfur or no sulfur, the sulfur paste discharged from the sulfur discharge valve will contain more impurities and cannot meet the sales standards.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

The terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0019] The present application provides a molten sulfur kettle output pipe, such as Figure 1 As shown, the output pipe of the molten sulfur kettle includes a clear liquid pipeline 10 and a sight glass 12. The two ends of the clear liquid pipeline 10 are respectively connected to the clear liquid outlets of the circulation tank 60 and the molten sulfur kettle 62. The sight glass 12 is installed on the clear liquid pipeline 10, allowing the operator to observe the purity of the clear liquid in the clear liquid pipeline 10.

[0020] When the output pipe of the molten sulfur kettle is used to transport the clear liquid produced by the molten sulfur kettle 62 to the circulation tank 60, the operator can observe the purity of the clear liquid through the sight glass 12, and then adjust the sulfur discharge valve and the valve on the clear liquid pipeline 10 according to the purity of the clear liquid, and then adjust the content of sulfur in the clear liquid, so that the sulfur paste discharged from the sulfur discharge valve can meet the sales standard and avoid the accumulation of sulfur in the clear liquid in the circulation tank 60.

[0021] Reference Figures 2 to 5 As shown, in the embodiment of the present application, the sight glass 12 includes a transparent tube 14, two connecting components 16 and a plurality of screws 58.

[0022] The connection assembly 16 includes a steel pipe 18, and an outer flange 20 and an inner flange 22 connected to both ends of the steel pipe 18. The outer flanges 20 of the two connection assemblies 16 are used to connect with the clear liquid pipeline 10; specifically, two flanges corresponding to the two outer flanges 20 are provided on the clear liquid pipeline 10, and the two outer flanges 20 are connected to the two flanges on the clear liquid pipeline 10 by bolts or the like.

[0023] The two inner flanges 22 are coaxially arranged, and the two ends of the plurality of screw rods 58 are respectively connected to the two inner flanges 22. Specifically, the two ends of the screw rods 58 pass through the two inner flanges 22, and nuts are arranged on both sides of each inner flange 22 to connect the screw rods 58 to the inner flanges 22, thereby connecting and fixing the two connection assemblies 16, and keeping the distance between the two inner flanges 22 fixed.

[0024] The two ends of the transparent tube 14 are respectively connected to the end faces of the two inner flanges 22, and are connected to the steel pipe 18 of each connecting assembly 16. For example, the two ends of the transparent tube 14 can be connected to the end faces of the two inner flanges 22 by bonding with glue, and the transparent tube 14 can be a glass pipe or a resin pipe, etc. During the use of the molten sulfur kettle 62, the operator can observe the clear liquid flowing out of the molten sulfur kettle 62 through the transparent tube 14, and then determine whether it is necessary to adjust the valve on the sulfur discharge valve and the clear liquid pipeline 10; and when adjusting the valve on the sulfur discharge valve and the clear liquid pipeline 10, the operator can observe the transparent tube 14 while adjusting.

[0025] During the use of the sight glass 12, the transparent tube 14 is easily knocked off or broken, which causes the clear liquid to be unable to flow into the circulation tank 60. At this time, the molten sulfur kettle 62 needs to be closed and the sight glass 12 needs to be replaced before production can be resumed. In order to prevent the transparent tube 14 from falling off or breaking, as shown in the following example, Figures 2 to 5As shown, the connection assembly 16 further includes a support 28, a spring 30 and a blocking member 32. The support 28 is connected to the steel pipe 18, and the support 28 is located between the outer flange 20 and the inner flange 22. The inner flange 22 is provided with a through hole 24, and the blocking member 32 can slide through the through hole 24. Moreover, when one end of the two blocking members 32 abuts against the inner flange 22 of another connection assembly 16, the two blocking members 32 completely surround the transparent tube 14. The two ends of the spring 30 are respectively connected to the support 28 and the blocking member 32, and the spring 30 always applies an elastic force to the blocking member 32 in a direction away from the support 28.

[0026] In each connecting assembly 16, the spring 30 can exert elastic force on the blocking member 32, so that one end of the blocking member 32 is pressed against the inner flange 22 of another connecting assembly 16, such as Figure 4 and Figure 5 As shown; at this time, the two blocking members 32 completely surround the transparent tube 14, so that the transparent tube 14 is protected and not bumped. When it is necessary to observe the transparent tube 14, the operator can operate the blocking member 32 to move the blocking member 32 in each connecting assembly 16 toward the support 28, so that the two blocking members 32 no longer completely surround the transparent tube 14. Figure 2 and Figure 3 As shown, the operator can observe the clear liquid flowing through the transparent tube 14.

[0027] When the operator moves the two blocking members 32 toward the support 28, the operator can observe the clear liquid flowing through the transparent tube 14. However, since the spring 30 always exerts an elastic force on the blocking member 32 away from the support 28, in order to fix the position of the blocking member 32 when observing the transparent tube 14, the connecting assembly 16 also includes a first clamping portion 38 and a second clamping portion 48. Figures 2 to 5 The first clamping portion 38 is connected to the support 28 ; the second clamping portion 48 is connected to the blocking member 32 and is configured to be detachably connected to the first clamping portion 38 .

[0028] When it is necessary to observe the clear liquid, the operator moves the two blocking members 32 toward the support 28 and connects the first clamping portion 38 with the second clamping portion 48 to fix the positions of the two blocking members 32. This allows the operator to observe the transparent tube 14 and adjust the sulfur release valve and the valve on the clear liquid pipeline 10 without having to hold the position of the blocking member 32 by hand. At the same time, one operator can perform the above operations, saving manpower.

[0029] Specifically, the embodiment of the present application provides a specific structure of the first clamping portion 38 and the second clamping portion 48. Figure 3 , Figure 5 and Figure 6As shown, the first clamping portion 38 includes a connecting plate 40 and a fixing plate 42; the connecting plate 40 is connected to the fixing plate 42 and the support 28; the fixing plate 42 is arranged between the support 28 and the blocking member 32, and the fixing plate 42 is provided with a connected long hole 44 and a through hole 46, and the width of the through hole 46 is greater than the width of the long hole 44. Figure 8 As shown, the second clamping portion 48 includes a rotating ring 50, a connecting rod 52 and a clamping block 54; the rotating ring 50 can be connected to the blocking member 32 rotatably around the axis of the steel pipe 18; one end of the connecting rod 52 is connected to the rotating ring 50, and the other end of the connecting rod 52 is connected to the clamping block 54. The clamping block 54 is used to pass through the fixing plate 42 from the through hole 46, and when the rotating ring 50 rotates, the connecting rod 52 enters the long hole 44, and the clamping block 54 presses the end surface of the fixing plate 42 away from the blocking member 32.

[0030] When the position of the blocking member 32 needs to be fixed, the clamping block 54 is first aligned with the through hole 46, and the rotating member is operated to make the clamping block 54 pass through the through hole 46; then the rotating member is rotated to move the connecting rod 52 into the long hole 44, and the clamping block 54 is pressed against the end face of the fixing plate 42 away from the blocking member 32, so that the first clamping portion 38 is connected with the second clamping portion 48, and then the fixing plate 42 can fix the position of the blocking member 32 through the second clamping portion 48. When the blocking member 32 is needed to protect the transparent tube 14, the rotating member is first rotated to move the connecting rod 52 to the through hole 46, and the clamping block 54 is aligned with the through hole 46; then the rotating member is released, and the blocking member 32 moves under the action of the spring 30, and drives the clamping block 54 to pass through the through hole 46, until the blocking member 32 abuts against the inner flange 22 of another connecting assembly 16, and at this time, the two blocking members 32 completely surround the transparent tube 14.

[0031] Reference Figure 7 As shown, the blocking member 32 includes a supporting portion 34 and a blocking portion 36 .

[0032] The support portion 34 is located on the side of the inner flange 22 facing the outer flange 20 and is connected to one end of the spring 30. The spring 30 applies an external force to the support portion 34, so that the blocking member 32 can press the inner flange 22 of another connecting assembly 16.

[0033] The blocking portion 36 can slide through the through hole 24, and one end of the blocking portion 36 is connected to the supporting portion 34. When the ends of the two blocking portions 36 away from the blocking portion 36 are both in contact with the inner flange 22 of the other connecting assembly 16, the two blocking portions 36 completely surround the transparent tube 14. Specifically, the blocking portion 36 of each blocking member 32 can cover 180° around the periphery of the transparent tube 14, so that the blocking portions 36 of the two blocking members 32 completely surround the transparent tube 14; illustratively, Figure 7 It is shown that the blocking portion 36 is divided into two symmetrically arranged parts.

[0034] like Figure 3 As shown, a groove 26 for fixing the end of the blocking portion 36 is formed on the end surface of the inner flange 22 facing the transparent tube 14 .

[0035] Continue to refer to Figure 8 The second clamping portion 48 further includes a handle 56, one end of which is connected to the rotating ring 50. The handle 56 facilitates the operator to operate the rotating ring 50. When the rotating ring 50 needs to be rotated, the operator can apply external force to the handle 56 to drive the rotating ring 50 to rotate.
