Abstract
The utility model is the anti-blocking and blowing cleaner of a kind of powder sampling line, comprise powder carry pipeline, be located at the sampling groove in powder carry pipeline, described sampling groove is connected with sampling line entrance point, sampling line is provided with sampling cock and lower sampling cock, described sampling line outlet end is provided with sampling cabinet, is provided with a blow line between described upper sampling cock and lower sampling cock, and described blow line is provided with one for carrying inert gas valve and the pressure gauge of inert gas.Powder sampling line of the present utility model is anti-blocking has structure simply with blowing cleaner, easy to maintenance; Practical, sampling is convenient, can be applicable to other and holds susceptible to plugging dead angle pipeline purging and anti-blocking advantage.
Description
Technical field
The utility model is the anti-blocking and blowing cleaner of a kind of powder sampling line, is applicable to powder deposition, the pipeline easily resulted in blockage.
Background technique
In p-phthalic acid (PTA) production technology, in order to the quality of the thick product coarse terephthaldehyde (CTA) of periodic monitor, every four hours, sample analysis is carried out once to CTA under normal circumstances, but in CTA product containing about 3000ppm to carboxyl benzoic acid (4-CBA) and other impurity, because powder viscosity is large, poor fluidity, very easily deposits and causes pipeline to block in sampling line.Because Jiaxing petrochemical industry PTA process units previously this type of accident often occurred, usual way is that dismounting pipeline valve carries out pass blocking, not only causes sampling difficulty, manpower waste, also causes powder to lose and serious environment pollution.
Practical content
The purpose of this utility model is to solve technological deficiency that sample collector pipeline often blocks and provide a kind of powder sampling line anti-blocking and blowing cleaner, putty problem when this device can effectively avoid CAT to sample.
In order to achieve the above object, anti-blocking and the blowing cleaner of a kind of powder sampling line designed by the utility model, comprise powder carry pipeline, be located at the sampling groove in powder carry pipeline, described sampling groove is connected with sampling line entrance point, sampling line is provided with sampling cock and lower sampling cock, described sampling line outlet end is provided with sampling cabinet, be provided with a blow line between described upper sampling cock and lower sampling cock, described blow line is provided with one for carrying inert gas valve and the pressure gauge of inert gas.
As preferably, described inert gas is nitrogen.
Further, described sampling cabinet is with switch gate.
This anti-clogging is included on sampling line and sets up first valve, one group of inert gas valve and blow line are set between twice sampling cock, sampling line outlet arranges sampling cabinet (belt switch door), separately in powder carry pipeline, arranges sampling groove.When not sampling, upper sampling cock and nitrogen valve are opened, and lower sampling cock cuts out, and keep one small flow inert gas blowback to enter conveying supervisor, prevent buildup blocking in sampling line.During sampling, close nitrogen valve, open the sampling of lower sampling cock.If when lower sampling cock place is blocked up, shut sampling cock and drive lower sampling cock, open nitrogen valve and purge block clearing.Wherein pressure gauge is for controlling the pressure of inert gas in pipeline, in case pipeline blast.
Anti-blocking and the blowing cleaner of powder sampling line of the present utility model has and has advantage below: structure is simple, easy to maintenance; Practical, sampling is convenient, can be applicable to other and holds susceptible to plugging dead angle pipeline and to purge and anti-blocking.
Accompanying drawing explanation
Fig. 1 is the structural representation of the anti-blocking Powder sample of the utility model.
Shown in figure: 1 powder carry pipeline, 2 sampling grooves, sampling cock on 3,4 times sampling cocks, 5 inert gas valve, 6 sampling cabinets, 7, blow line.
Embodiment
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
As shown in Figure 1, the utility model is the anti-blocking and blowing cleaner of a kind of powder sampling line, comprise powder carry pipeline 1, be located at the sampling groove 2 in powder carry pipeline, described sampling groove is connected with sampling line entrance point, sampling line is provided with sampling cock 3 and lower sampling cock 4, described sampling line outlet end is provided with sampling cabinet 6, be provided with a blow line 7 between described upper sampling cock and lower sampling cock, described blow line is provided with one for carrying inert gas valve 5 and the pressure gauge 7 of inert gas.
This anti-clogging arranges one group of inert gas valve and blow line between twice sampling cock, and sampling line outlet arranges sampling cabinet (belt switch door), separately in powder carry pipeline, arranges sampling groove.When not sampling, upper sampling cock and nitrogen valve are opened, and lower sampling cock cuts out, and keep one small flow inert gas blowback to enter conveying supervisor, prevent buildup blocking in sampling line.During sampling, close nitrogen valve, open the sampling of lower sampling cock.If when lower sampling cock place is blocked up, shut sampling cock and drive lower sampling cock, open nitrogen valve and purge block clearing.Wherein pressure gauge is for controlling the pressure of inert gas in pipeline, in case pipeline blast.It is simple that it has structure, easy to maintenance; Practical, sampling is convenient, can be applicable to other and holds susceptible to plugging dead angle pipeline purging and anti-blocking advantage.
Above specific embodiment of the utility model is described.It is to be appreciated that the utility model is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present utility model.
