Description
Technical field
The present invention relates to a kind of self-priming novel liquid sulfur pump, this pump is mainly for chemical industry as the high temperature such as sulphur, poisonous and harmful, and viscosity is large, easy crystallization, severe corrosive operating mode.
Background technique
Sulphur is a kind of poisonous and hazardous industrial chemicals, it is solid at normal temperatures, when the temperature of sulphur reaches fusing point, sulphur has the liquid sulfur of flowing property by being melt into, the viscosity with temperature of molten sulfur and changing, viscosity with temperature during general incipient melting raises and declines, and after temperature is more than 159 DEG C, viscosity with temperature raises and sharply increases.When continuing raising temperature and reaching 190 DEG C, the viscosity of sulphur reaches maximum, and after temperature is more than 190 DEG C, viscosity returns to again feature at the beginning, and 130 ~ 160 DEG C time, viscosity is minimum, is beneficial to the conveying of molten sulfur.Once sulphur can decline and condense in pump and pipeline by Yin Wendu in termination of pumping pipeline and pump, cause and again open pump difficulty, mechanical seal damages.Because of the physical property that it is special, the conveying of molten sulfur is a difficult problem always.At present the normal transfer pump adopted is long shaft submerged pump, during this pump startup impeller submergence in media as well, thus start easily, can not run difficulty in optimum temperature range because of medium temperature, do not need the problem of consideration suction lift and be used widely.But long shaft submerged pump inconvenient maintenance, sliding bearing is perishable and wear and tear, and sliding bearing is once dry grinding exists very large potential safety hazard, and pump shaft vibration swings greatly and is subject to dielectric corrosion, and rate of fault is high.
Summary of the invention
The object of the invention is the deficiency for existing in above-mentioned technology, a kind of self-priming novel liquid sulfur pump is provided.
The object of the present invention is achieved like this: comprise transfer pump, self-priming apparatus, heating device, reflux pipeline four part.It is characterized in that, transfer pump adopts vane pump, self-priming apparatus comprises vacuum pumping device, control box and pipeline of bleeding, when in transfer pump, liquid level reaches desired location, vacuum pumping device sends electrical signal to control box to control the automatic start-stop of vacuum pumping device and transfer pump, realizes the automatic control of whole equipment.Rear because leaving liquid container for preventing medium to be sucked up, external temperature declines and condenses, cause medium to carry, liquid sulfur pump arranges heating device, and heating device arranges steam inlet and steam (vapor) outlet, tracing steam is provided by outside heating network, all pipelines, connector exterior are equipped with overcoat TRACER, and pump cover, the pump housing are all provided with the hot chamber of companion, in TRACER and to accompany in hot chamber logical steam, steam enters from steam inlet, flows back into outside heating network from steam (vapor) outlet.Remain in pump and medium condensation in pipeline after preventing termination of pumping, cause when again opening pump because of pipeline blockage, in mechanical seal Seal cage, medium crystallization etc. cause equipment to run, pump discharge pipeline adds reflux pipeline and outer pipe valve, when whole device needs to stop transport, closes outer pipe valve, transfer pump continues to keep small flow to run, reflow pipe valve open, pumped medium flows back to liquid container along reflux pipeline, is no longer transported to next pump position.When device recovers running, closing volume tube valve, open outer pipe valve, transfer pump recovers normal operating condition rapidly.According to different operating mode and device structure form, vacuum pumping device adopts entrance to vacuumize and vacuumizes two kinds of modes with top and vacuumize to transfer pump; One, vacuum pumping device adopts entrance to vacuumize mode and vacuumizes to transfer pump, pipeline of bleeding is provided with entrance exhaust tube and top exhaust tube, entrance exhaust tube one end connects vacuum pumping device, the other end connects inlet duct, exhaust tube one end, top connects vacuum pumping device, and the other end connects transfer pump pump chamber top; Its two, vacuum pumping device adopts top to vacuumize mode and vacuumize to transfer pump, and pipeline of bleeding is provided with top exhaust tube, and exhaust tube one end, top connects vacuum pumping device, and the other end connects outer pipe or the pump chamber top of transfer pump, and pipeline of bleeding is higher than pump spiral case top.
When transfer pump termination of pumping is overhauled, in vertical pump, residual medium can along vertical inlet duct automatic back flow to liquid container, a small amount of residual medium is had lower than inlet leg portion in horizontal pump, for ensureing that this place's medium energy automatic back flow is to liquid container, liquid-discharging tube can be established in liquid port place bottom horizontal pump, liquid-discharging tube normally open, because liquid-discharging tube is very thin, a small amount of backflow can not impact transfer pump, after transfer pump termination of pumping, in pump, residual medium flows back to liquid container along liquid-discharging tube, residual pump bottom dielectric emptying medium and crystallization because operator forgets after preventing termination of pumping, without the need to manual operation.Self-priming apparatus extracts gas in transfer pump and realizes automatically sucting of transfer pump.
Beneficial effect of the present invention: 1, complete machine pump is on ground, easy to maintenance; 2, pump shaft and the pump housing do not insert in medium, not fragile; 3, water is not needed, energy self-priming; 4, inhale journey high, 7 meters can be reached; 5, medium fills pump and just opens pump, avoids machine to seal dry grinding; 6, all additional steam tracing such as all pipelines, joint, the pump housing, pump cover, because of heat loss when flowing through pump after preventing medium to leave liquid container, temperature declines and condenses; 7, reflux pipeline can anti-locking apparatus when stopping transport, and causes residual medium in pump to condense in transfer pump without media flow; 8, during vertical pump termination of pumping, in pump, medium is back in liquid container along vertical portals pipe automatically, horizontal pump arranges liquid-discharging tube, after termination of pumping, in pump, residual medium is back to liquid container along liquid-discharging tube automatically, without the need to manual operation, residual pump bottom dielectric emptying medium and crystallization because operator forgets after preventing termination of pumping, when again opening pump, pump damages.
