Description
Technical field
This utility model relates to field of chemical equipment, particularly relates to a kind of probe tube for continuous solid body reaction.
Background technology
As the term suggests probe tube is a kind of sampling equipment, it is possible to continuous print chemical reaction is sampled detection, is used for monitoring response situation, has very important practical significance.For sampling product form difference or use scene difference, probe tube has different designs, for instance the probe tube for liquid and solid just has different designs.
Such as, the solid probe tube for solidification chemical product samplings such as powder, little granule, small crystalss on market, probe tube when inspecting by random samples for finished product is generally adopted following design:
It is made up of a pipe, one elongated slot of opening one side, front opening.Inserting material along certain angle during sampling, now notch should be downward, rotates several times, ensures that taken material should upwards, then be poured in shuttle by notch, complete primary sample task during extraction.Discharge ram blowing can be used for not loose solid.
Sampling in addition with product, probe tube is also applied to the sampling in course of reaction and detects, and the problem that blocking easily occur in the solidification chemical products such as the powder in product, little granule, small crystals.It is different from the probe tube of finished product detection, if the problem that the probe tube of detection course of reaction runs into blocking, it is necessary to probe tube would be taken out from reaction vessel cleaning and installs again, be unfavorable for the continuous monitoring of course of reaction.
The Chinese patent literature that publication number is CN1995955 discloses a kind of axial multipoint-parallel vacuum type solid particles sampling device for fluidized bed, it is made up of probe tube, valve and sampling room, one end of probe tube is connected with sampling room with tremie pipe by valve, tremie pipe is arranged on upper cover place of sampling room, at sampling room's upper cover equipped with blow-down pipe and vacuum-pumping tube, in sampling room, position, middle and lower part place is provided with drainage screen, and the pyramidal structure bottom sampling room is connected with a tapping valve.In this technical scheme, solid particle easily blocks the sampling entrance of probe tube, causes that sampling is inaccurate.
Therefore, people devise the structure that some are anti-blocking.The Chinese patent literature that such as publication number is CN203259380U discloses the flue gas sampling device preventing line clogging, it includes discharge flue, discharge flue is stretched in one end gas sampling probe and the smoke sampling device being connected with gas sampling probe, connected by flanged pipe between discharge flue and smoke sampling device, anti-blocking sleeve pipe it is provided with between described gas sampling probe and flanged pipe, discharge flue is stretched in described anti-blocking sleeve pipe one end, it stretches into the length of discharge flue and stretches into the length of discharge flue more than gas sampling probe, and the other end of anti-blocking sleeve pipe is affixed with smoke sampling device.This technical scheme wraps up probe tube by anti-blocking sleeve pipe and realizes anti-blocking purpose, but anti-blocking while also result in being relatively isolated of probe tube and sample, reduce the accuracy of sampling.
Utility model content
For the deficiency that prior art exists, this utility model provides a kind of detection accurately, easy to use, the probe tube for continuous solid body reaction of simple in construction.
The technical solution of the utility model is:
A kind of probe tube for continuous solid body reaction, including the probe tube on the sidewall being installed through reaction vessel, this probe tube includes the head stretching into reaction vessel and is positioned at the afterbody outside reaction vessel, this probe tube is being placed with multiple sampling entrance from head to the sidewall of reaction vessel towards the side in material movement direction, being provided with inside probe tube and fall into material and at probe tube afterbody and the extraneous sampling cavity communicated with for compression air imports the air chamber of sampling cavity for accepting sampling entrance, this air chamber passes through gas source pipe and is connected with compressed gas source.
Material is received into sampling cavity by the sampling entrance on pipe shaft by probe tube, and in order to improve efficiency, sampling entrance is provided with multiple on pipe shaft, by being arranged on the opening of probe tube afterbody, it is possible to taken out from sampling cavity by sample.An air chamber being relatively isolated with sampling cavity it is additionally provided with inside probe tube, material can not fall in air chamber, but the gas in air chamber and the gas in sampling cavity communicate, compressed air pump can be entered in air chamber by compressed gas source, thus the pressure formed in sampling cavity is more than the pressure in reaction vessel, form the recoil of sampling entrance, it is prevented that blocking.
As preferably, the sidewall of described reaction vessel is provided with the flange-interface of perforate, and the afterbody of described probe tube is fixed with the flange seat being connected with this flange-interface.
Probe tube needs the needs according to reaction to select to install, and in order to facilitate the installation of probe tube, the sidewall of reaction vessel is provided with the flange-interface of autonomous closure, the convenient closed reaction vessel when installing probe tube.When probe tube installed by needs, flange-interface is opened, insert probe tube, bolt and hanger in place orchid seat and flange-interface.
As preferably, the afterbody of described probe tube is hinged with for closing the sampling cavity cover plate at the opening of probe tube afterbody.
When carrying out recoil operation, if the opening that sampling cavity is positioned at probe tube afterbody is opened, compression air can be escaped a part of from opening, the effect of impact recoil, therefore design has the cover plate that can close so that sampling cavity only sampling entrance, as rushing down pressure passageway, improves the effect of back flushing anti-clogging.
As preferably, described air chamber is evenly arranged in the inside of probe tube side, material movement direction dorsad, and air chamber is provided with the rib preventing material from falling into air chamber in the inside of probe tube near one end of head.
Manufacturing in order to convenient, air chamber tiled arrangements is in the lower section of sampling cavity, and the top sidewall of air chamber is the lower sidewalls of sampling cavity.In order to improve repercussion effect, the gas of air chamber rearwardly moves from the head of probe tube, causing unnecessary trouble to prevent the material when sampling operation or recoil operation from falling into air chamber, the top sidewall of air chamber is flipping up formation rib near probe tube head.
As preferably, described gas source pipe is arranged on the afterbody of described probe tube.
In order to facilitate connection and the installation of gas source pipe, the afterbody of probe tube is positioned at the outside place of reaction vessel and is connected to the gas source pipe leading to air chamber.
As preferably, described gas source pipe is provided with releases valve soon.
The effect of the air of compression is in that the material of recoil sampling blocked inlet, if insufficient pressure, can not play the effect of recoil, and therefore valve is selected and released valve soon.
This utility model has the advantage that
(1) the internal recoil design of probe tube, does not affect the contact between reaction vessel and probe tube, and detection is accurate,
(2) air chamber supply design, it is not necessary to take out probe tube and can solve blockage problem, easy to use；
(3) simple in construction is stable in use procedure.
