Abstract
The invention relates to an integral heat-insulated sulfur pump, which comprises a pump shaft, a pump body and an impeller. Outer layers of the pump body and a delivery pipe are provided with a layer of heat-insulated jacket, and hot water or vapor is filled into the jacket, so that the temperature of the whole pump body and the whole delivery pipe can be always maintained higher than that of sulfur crystallization, namely guarantee can be made that liquid sulfur, instead of sulfur crystal, is conveyed out of the pump body, thereby the sulfur pump can maintain normal operating state. The integral heat-insulated sulfur pump has the characteristics of simple structure, convenient maintenance, high production efficiency and so on.
Description
Technical field: the present invention relates to a kind of sulphur pump that is used to carry liquid, particularly relate to a kind of integral thermal insulation type sulfur pump.
Technical background: in chemical engineering industry is produced, can produce a large amount of sulphur liquid,, can cause very serious pollution to environment if these liquid are not handled.But when these liquid are carried, use general pump, can not satisfy production requirement.Because normal temperature is carried Molten sulphur down, having crystalline solid produces, the pipeline of granular crystalline solid meeting block pumps, thereby cause the obstruction of pipeline, have a strong impact on the proper functioning of pump, though some product has adopted the partly method of heating now, but can not fundamentally solve the existing defective of sulphur pump.
Summary of the invention: purpose of the present invention will provide a kind of integral thermal insulation type sulfur pump exactly, and it can fundamentally solve above existing defective, reduces and reduce the generation of crystalline solid effectively, thereby guarantees the proper functioning of liquid sulfur pump.The object of the present invention is achieved like this, integral thermal insulation type sulfur pump is made up of the pump housing, impeller, dunnage, it is characterized in that: the skin of sulphur liquid discharge tube all is provided with one deck thermal insulation layer chuck on the skin of described dunnage lower pump body and dunnage, and an end of described thermal insulation layer chuck is fixed on the flange plate of liquid outlet; Be provided with the hot water inlet on the top of thermal insulation layer chuck; Bottom at described dunnage upper end thermal insulation layer chuck is provided with the hot water connecting tube, and pump housing thermal insulation layer chuck set under described hot water connecting tube and the dunnage links to each other; Bottom at the pump housing is provided with the hot water outlet pipe, and described hot water outlet pipe is joined through dunnage and discharge tube flange plate.The present invention is simple in structure, and is easy for installation, can overcome the defective of old-fashioned sulphur pump better, improved productivity effect.
Description of drawings: Fig. 1 is a structural representation of the present invention;
1. pump shaft, 2. dunnage, 3. sulphur liquid discharge tube, 4. hot water connecting tube, 5. discharge tube flange plate, 6. hot water inlet fixing frame, 7. hot water inlet, 8. thermal insulation layer chuck, the 9. pump housing, 10. impeller, 11. hot water outlet pipes.
Specifically revolve mode in fact: the invention will be further described below in conjunction with accompanying drawing:
In the drawings, integral thermal insulation type sulfur pump is made up of the pump housing 9, impeller 10, dunnage 2, it is characterized in that: the skin of sulphur liquid discharge tube 3 all is provided with one deck thermal insulation layer chuck 8 on the skin of described dunnage 2 lower pump bodies 9 and dunnage 2, and an end of described thermal insulation layer chuck 8 is fixed on the flange plate of sulphur liquid discharge tube 3; Be provided with hot water inlet 7 on the top of thermal insulation layer chuck 8; Bottom at described dunnage 2 upper end thermal insulation layer chucks 8 is provided with hot water connecting tube 4, and 2 times set pump housing thermal insulation layer chucks 8 of described hot water connecting tube 4 and dunnage link to each other; Be provided with hot water outlet pipe 11 in the bottom of the pump housing 9, described hot water outlet pipe 11 is joined through dunnage 2 and discharge tube flange plate 5.During concrete enforcement, with boiling water or high temperature, the steam of high pressure injects from the hot water inlet that is fixed on the sulphur liquid discharge tube flange plate, hot water flows in the thermal insulation layer chuck, flow in the thermal insulation layer chuck of dunnage lower floor in the thermal insulation layer chuck on dunnage upper strata through the superheated water connecting tube, because the thermal insulation layer chuck is to be wrapped in the skin of the pump housing and the skin of output tube, the continuous like this high temperature that pours in, high-pressure water heating or steam will heat constantly for the output tube and the pump housing, make the temperature of the pump housing, and the temperature of output tube can remain at more than the temperature of Molten sulphur crystallization, bottom at the Molten sulphur pump is provided with the hot water discharge pipe, and the hot water that has circulated can automatically be discharged outside the sulphur pump housing.Like this, when the Molten sulphur pump with the sulphur of liquid state in the impeller suction pump housing because the temperature of the pump housing is higher than the solidification point of sulphur all the time, that is to say in liquid delivery tube, to remain liquid sulphur state.So just can not cause transfer pump because sulphur crystallization and blocked situation has also just guaranteed the normal operation of the pump housing.
