Abstract
The utility model relates to a blockage proof blowing pressure sampler, which is used for gas medium with dust. The utility model comprises a plurality of air chambers which are composed of cylinders, a plurality of tip cones whose tops face upwards and cone funnels. The dynamics and expansion principles of gas are utilized to separate the dust from the gas, and the gas after being sampled can not generate blockage to a pressure-transferring tube. The utility model has the advantages of simple structure and reliable work, which is particularly suitable to be used in a powder-conveying system of a power plant.
Description
The utility model relates to a kind of anti-blocking blast pressure vessel that is used to contain the gas medium of dust.
When measuring blast on gas pipeline that contains dust and equipment, connecting pipe is blockage phenomenon usually, causes to measure actual pressure.In order to address the above problem, there is several different methods to adopt in the prior art, as utility model patent 89217997.X.But its shortcoming is: be that the top that some dust directly enters cylindrical shell by two conical hopper mouths with gas is stopped up sampler.
The purpose of this utility model is for avoiding above-mentioned deficiency that a kind of anti-blocking blast pressure vessel is provided, can more effectively avoiding the obstruction of connecting pipe.
The utility model is achieved in that it has a cylindrical tube 1, and cylindrical shell 1 upper end is equipped with pressure guiding pipe 4, and cylindrical shell 1 lower end joins by conical hopper 10 and inlet tube 7.Top in cylindrical shell 1 is provided with a conical hopper 2, below conical hopper, cause and also have two top addendum cone 3 and conical hoppers 6 up less, report to the leadship after accomplishing a task mutually in its position, leave circular passage 8 between addendum cone 3 and the cylindrical shell 1 and connect by rotating vane 9 between them, the big end of conical hopper 2 links to each other with cylindrical shell 1 inwall.
In sum, its working mechanism is as follows: inlet tube 7 of the present utility model links to each other with trunk line, and the gas that contains dust enters from inlet tube 7, enters cylindrical shell through bottom outlet 5.At this moment, most dust is stopped by the addendum cone face, a part of dust is crossed circular passage 8 with air communication and is entered cylindrical shell 1 upper strata, because the effect of rotating vane forms swirling eddy, and the centrifugation of swirling eddy make most of dust to around scatter, the male cone (strobilus masculinus) of running into conical hopper 10 is then stopped, center air-flow partly contains dust, and to change dirt less, enter taper leakage 6 by bottom outlet 5 and carry out second level separation, its separating mechanism is identical with the first order.At last, the gas that comparatively purifies enters pressure guiding pipe 4 by the bottom outlet 5 of conical hopper 2.
Now in conjunction with the accompanying drawings embodiment of the present utility model is described as follows:
Fig. 1 is a cut-open view of the present utility model
Embodiment of the present utility model has a columniform cylindrical shell 1 as shown in Figure 1, and pressure guiding pipe 4 is equipped with in the upper end of cylindrical shell 1, and pressure guiding pipe 4 is connected mutually with the bottom outlet 5 of the conical hopper 2 of cylindrical shell 1 internal upper part.The lower end of cylindrical shell 1 is connected mutually with the big end of conical hopper 6.The lower end of cylindrical shell 1 is connected mutually with the big end of conical hopper 6, and the bottom of conical hopper 6 then links to each other with inlet tube 7.A top addendum cone that makes progress 3 is installed in the below of the conical hopper 2 in the cylindrical shell 1, its big end external diameter is less than the cylinder inboard wall diameter, form a circular passage 8, the big end of addendum cone 3 connects firmly by 6 rotating vanes 9 and cylinder inboard wall, and respectively one of conical hopper 6 and addendum cone 11 then is installed below addendum cone 3.
Claims (2)
1, a kind of anti-blocking blast sampler that is used for containing the gas pipeline and the equipment of dust, comprise cylindrical shell, conical hopper and addendum cone, it is characterized in that: the top in cylindrical shell (1) is provided with a conical hopper (2), a top addendum cone that makes progress (3) is installed in the below of conical hopper (2), leave circular passage (8) between the inwall of addendum cone (3) and cylindrical shell (1), a pair of conical hopper (6) and addendum cone (11) at least also are housed below addendum cone.
2, anti-blocking blast sampler according to claim 1 is characterized in that addendum cone (3), (12) in the cylindrical shell (1) connect firmly by the inwall of rotating vane and cylindrical shell (1).
