[0002] Sulfur pumps are a type of chemical process pump. Sulfur is solid at room temperature, but it becomes liquid when heated to about 135-155℃, making it easy to transport.
[0003] During shutdown and pauses, sulfur in existing sulfur pumps can solidify inside the pump body, causing the pump to stop flowing or become stuck. Typically, a double-layer pump casing is used, with the inner layer serving as a flow channel for liquid sulfur and the outer layer as an insulation jacket. However, the existing insulation jacket is a one-piece structure. When the insulation jacket is damaged, the entire pump body will be damaged, resulting in high maintenance costs and increased equipment production costs. Summary of the Invention

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Referring to Figures 1-2 and 5, the present invention provides a liquid sulfur pump with a heat-insulating jacket, comprising: a pump body 4 and a spiral blade 12 installed in the pump body 4. The pump body 4 has a disc-shaped structure, and heat-insulating plates 3 are provided on both sides of the disc-shaped structure for heat preservation. Each heat-insulating plate 3 is provided with mounting parts around its perimeter, and one end of each mounting part is installed on the outer wall of the pump body 4.
[0026] As shown in Figures 1-2, the pump body 4 is also provided with a discharge pipe 7 for discharging material on the side opposite to the rotating shaft 2, and another heat preservation plate 3 is sleeved on the discharge pipe 7. The pump body 4 is provided with a feed pipe 5 for feeding material on its outer periphery.
[0027] As shown in Figure 1, a motor 1 for rotational drive is also provided on the axis of one side of the pump body 4. The output end of the motor 1 is provided with a rotating shaft 2 connected to the spiral blade 12, and one of the heat preservation plates 3 is sleeved on the rotating shaft 2.
[0028] The above describes the use of the main body, spiral blade 12, two heat-insulating plates 3, and multiple mounting components provided by this utility model. One heat-insulating plate 3 is fitted onto the rotating shaft 2, and the other heat-insulating plate 3 is fitted onto the discharge pipe 7. After both heat-insulating plates 3 are attached to the pump body 4, the heat-insulating plates 3 are detachably installed in the pump body 4 through multiple mounting components. Thus, the heat-insulating plates 3 form heat-insulating areas on both sides of the pump body 4 to insulate the spiral blade 12, preventing sulfur from solidifying at the spiral blade 12.
[0029] Furthermore, to facilitate the even distribution of heat on the insulation plate 3, as shown in Figures 2 and 4, each insulation plate 3 is provided with an insulation chamber 13 for heat preservation. The insulation chamber 13 contains a ring pipe 15 for liquid heating, and multiple connectors are provided between two ring pipes 15 for communication. The ring pipes 15 facilitate the even distribution of liquid in the insulation plate 3. In the figures, there are two ring pipes 15 on the same side. The number of ring pipes 15 can be adjusted according to the size of the insulation chamber 13, but at least one ring pipe 15 is required. This ensures the even distribution of liquid on the insulation plate 3, thereby facilitating the formation of a high-temperature insulation zone on the side of the pump body 4 and preventing sulfur from solidifying within the pump body 4.
[0030] Furthermore, to facilitate the supply of heat to the insulation plate 3, as shown in Figures 1-3, each of the two insulation plates 3 is equipped with a heating pipe 6 and a heat return pipe 11. One end of the heating pipe 6 and the heat return pipe 11 are respectively connected to a ring pipe 15 on the same side. The heated liquid is supplied to one of the ring pipes 15 through the heating pipe 6, and then passes through the pump body 4 via the hose 9 to enter the other ring pipe 15. Finally, it flows back to the liquid heating device through the heat return pipe 11. The liquid heating device is existing technology and is not shown in the figures.
[0031] In this utility model, as shown in Figures 2 and 5, the pump body 4 of this embodiment has multiple heat-insulating through holes 14, which are arranged in a ring array outside the spiral blades 12, and multiple connecting parts pass through the corresponding heat-insulating through holes 14.
[0032] As shown in Figures 1-2, each connector includes a hose 9 and internal threaded joints 10 installed at both ends of the hose 9. The outer wall of the insulation plate 3 is provided with multiple external threaded pipe joints 8 that communicate with the ring pipe 15. Each internal threaded joint 10 is screwed onto the external threaded pipe joint 8 on the same side.
[0033] As described above, using the multiple heat-insulating through holes 14 provided by this utility model, multiple hoses 9 can pass through the pump body 4 and be close to the spiral blades 12. When the liquid flows in the hoses 9, a high-temperature channel is formed in the heat-insulating through holes 14. During this process, a high-temperature area is formed on the outside of the spiral blades 12 through the high-temperature channel. The high-temperature area provides high-temperature insulation for the outer periphery of the spiral blades 12. The hoses 9 are screwed onto the external threaded pipe joints 8 on the same side through the internal threaded joints 10, which facilitates the connection of the two heat-insulating plates 3 through the hoses 9, and facilitates the disassembly and replacement of the hoses 9 in the future.
[0034] In this utility model, as shown in Figures 1-5, the mounting component of this embodiment includes a plurality of mounting ears 16 and fixing bolts 17 mounted on the mounting ears 16, and each fixing bolt 17 is screwed onto the outer wall of the pump body 4.
[0035] As described above, when using the multiple mounting ears 16 and multiple fixing bolts 17 provided by this utility model, when the heat preservation plate 3 is attached to the outer wall of the pump body 4, the mounting holes on the mounting ears 16 are aligned with the threaded holes on the pump body 4. At this time, the fixing bolts 17 are screwed into the mounting holes and the threaded holes, thereby fixing the mounting ears 16 to the pump body 4, and then fixing the heat preservation plate 3 to the pump body 4.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
