Abstract
The utility model discloses a sampler for ferric sulfide grains, and belongs to the field of chemical equipment. The sampler comprises a vacuum collecting bottle, a casing, a sampler and a micro vacuum pump, wherein the sampler consists of a tubular sampling end, a rotating disc and a push type handle; the push type handle concentrically penetrates through the tubular sampling end to form a piston structure; the sampler is fixed on the casing through the rotating disc; a track on which the push type handle moves is arranged at the upper end of the casing; the mouth of the vacuum collecting bottle is coated with a double-layer sealing cover; an upper-layer sealing cover is fixed on a cover body; a fan-shaped collecting hole and a sucking hole are designed in the surface of the upper-layer sealing cover; a lower-layer sealing cover is fixed at the mouth of the collecting bottle; a fan-shaped collecting hole is designed in the surface of the lower-layer sealing cover; a bottle body knob is arranged at the bottom of the vacuum collecting bottle; a heating embedded jacket is embedded outside the vacuum collecting bottle; the micro vacuum pump is fixed inside the casing and is inserted into the sucking hole of the upper layer of the double-layer sealing cover through an air tube. The sampler is applied to vacuum drying of a ferric sulfide sample, the ferric sulfide sample is prevented from being oxidized, and sampling personnel are prevented from being poisoned.
Description
Technical field
The utility model is related to a kind of sampler for being used to gather iron sulfide corrosion products in petrochemical equipment, and more particularly to a kind of solid particle sampler belongs to field of chemical equipment.
Background technology
Petrochemical equipment inwall can form loose corrosion thin layer, and main component is iron sulfide.Iron sulfide has higher spontaneous combustion tendency, need to periodically sample detection.Document " Tank Containing Sulfur Oil is corroded and spontaneous combustion study mechanism "（Nanjing University of Technology, 2006）Research shows, iron sulfide rapid heat release and discharges sulfur dioxide gas under aerobic conditions.Document " refining equipment high temperature H2S corrosion products propensity and influence factor "（Industry security and environmental protection, 2009,35 (5):42-44）Research shows, can accelerate iron sulfide oxidation heat liberation under aqueous conditions.Under normal circumstances, under the conditions of equipment nitrogen charging, sample is gathered by solid sampler.But the structure design that existing solid sampler is dried without deoxygenation, it is impossible to protect fresh vulcanization iron sample, be oxidized easily, while sample exotherms may be caused to damage sampler and sampling personnel's sulfur dioxide poisoning.
The content of the invention
Technical problem to be solved in the utility model is：There is provided a kind of sampler for being used to gather iron-sulphide particles for being designed with vacuum drying function in view of the shortcomings of the prior art.
In order to solve the above technical problems, technical solutions of the utility model are as follows：
Sampler described in the utility model for iron-sulphide particles includes vacuum collecting bottle, housing, sampler, minipump, it is characterised in that：Sampler to form piston structure by tubular type sampling head, rotation dish, pusher handle composition, pusher handle with concentric wear of tubular type sampling head, and sampler is fixed on housing by rotation dish, and pusher handle motion track is left in housing upper end.Vacuum collecting bottle bottleneck is stamped double-layer seal lid, and upper strata closure is fixed on lid, and upper strata sealing cap surface is designed with fan-shaped collection port and aspirating hole, and lower floor's closure is fixed on collection bottle bottleneck, and lower floor's sealing cap surface is designed with fan-shaped collection port；Vacuum collecting bottom of bottle portion is provided with bottle knob, and the optional sample introduction in lower floor's closure sector open position or pumping are adjusted by rotating bottle knob；Heating is embedded with outside vacuum collecting bottle bottle nested, vacuum drying can be quickly completed.Minipump is fixed in housing, in the aspirating hole that double-deck capping upper strata is inserted by tracheae.
Lower floor's remaining area of sealing cap surface is stained with choke cotton.
Rotary handle is laterally sampled when using, sampling head, which is rotated to longitudinally through push handle bar, afterwards makes sample enter vacuum collecting bottle, open minipump nested with heating, the fan-shaped aperture position of rotating lower rotating seal lid regulation is evacuated, and quickly completes vacuum drying.
The utility model beneficial effect：
1st, the utility model is simple in construction, it is easy to operate, and deoxygenation and drying can be realized simultaneously.Heating in vacuum technology is compared with usual drying method, and the time is short, and effect is good, can ensure that vulcanization iron sample is fresh to greatest extent, it is not easy to be oxidized, while sampling personnel's sulfur dioxide poisoning can be prevented.
2nd, the utility model can realize the switching of sample introduction and pumping using Double layer rotating Seal Design, while the sealing property of vacuum collecting bottle is ensured that, with stronger applicable performance.
Brief description of the drawings
Fig. 1 is the utility model structural representation and use state figure；In figure, 1 is tubular type sampling head, and 2 be rotation dish, and 3 be pusher handle, and 4 be housing, and 11 be double-layer seal lid, and 5 be upper strata closure, and 6 be lower floor's closure, and 7 be minipump, and 8 is nested for heating, and 9 be vacuum collecting bottle, and 10 be bottle knob, and 12 be sampler.
Embodiment
It is as follows for embodiment with reference to accompanying drawing to be better illustrated to the utility model：
The iron-sulphide particles sampler includes vacuum collecting bottle 9, housing 4, sampler 12, minipump 7, it is characterised in that：Sampler 12 is made up of tubular type sampling head 1, rotation dish 2, pusher handle 3, and pusher handle 3 to form piston structure with concentric wear of tubular type sampling head 1, and sampler 12 is fixed on housing 4 by rotation dish 2, and the pusher tracks of handle 3 are left in the upper end of housing 4.Vacuum collecting 9 bottlenecks of bottle are stamped double-layer seal lid 11, and upper strata closure is fixed on lid, and the surface of upper strata closure 5 is designed with fan-shaped collection port and aspirating hole, and lower floor's closure is fixed on collection bottle bottleneck, and the surface of lower floor's closure 6 is designed with fan-shaped collection port；9 bottoms of vacuum collecting bottle are provided with bottle knob 10, and the optional sample introduction in lower floor's closure sector open position or pumping are adjusted by rotating bottle knob 10；Heating nesting 8 is embedded with outside vacuum collecting 9 bottles of bottle, vacuum drying can be quickly completed.Minipump 7 is fixed in housing 4, is inserted by tracheae on double-layer seal lid 11 in the aspirating hole of lid 5.
The utility model rotates sampling in use, pusher handle 3 rotarily drives tubular type sampling head 1 along trunnion axis.A certain amount of rear rotary motion disk 2 is taken to ordinate.Now, the injection port of tubular type sampling head 1 and double-layer seal lid is on the same axis.Longitudinal push handle 3 makes sample enter Dewar bottle.Reverse bottle knob 10 and make it that vacuum collecting bottle 9 and lower floor's closure 6 turn to the injection port that upper strata closure 5 is fully sealed in choke cotton.Start minipump 7 and heating nested 8, when the vacuum in vacuum collecting bottle 9 reaches predetermined value, 8 linkage nested with heating of minipump 7 is closed.Sampler is brought sample is taken out to vacuum glove box, complete sampling.
