Description

Rotary full-automatic pulverized coal sampling device Technical Field The utility model relates to the technical field of coal dust sampling, in particular to a rotary full-automatic coal dust sampling device. Background The coal dust sampler is equipment for periodically sampling coal dust on a primary air coal dust pipeline of a direct-fired pulverizing system, and usually uses compressed air as power to suck the coal dust by generating negative pressure through components such as a sampling tube, a separator, a sampling bottle and the like. The existing pulverized coal sampler is used for pumping pulverized coal from a pulverized coal pipe through an air pump in the actual use process, then the pulverized coal is led into a cyclone separator for separation, so that the pulverized coal enters a sampling bottle, and separated gas is led into the pulverized coal pipe again, but the sampling pipe rotates in the actual use process, so that the sampling pipe can transversely sample on the section of the pulverized coal pipe, and although sampling is carried out through a plurality of sampling ports distributed in an equal circle, the sampling is inconvenient to uniformly sample at a plurality of points. For this reason, new solutions need to be designed to solve. Disclosure of utility model The utility model aims to overcome the defects of the prior art, adapt to the actual needs, and provide a rotary full-automatic pulverized coal sampling device so as to solve the technical problem that rotary multi-point-position uniform sampling is inconvenient at present. In order to achieve the aim of the utility model, the technical scheme adopted by the utility model is that the rotary full-automatic pulverized coal sampling device comprises a fixed shell, wherein a first rotary joint is fixedly penetrated through one side wall of the fixed shell, the outer end of the first rotary joint is communicated with a cyclone separator through a first pipeline, the tail end of the cyclone separator is detachably fixed with a sampling bottle, and the rotary full-automatic pulverized coal sampling device further comprises: One end of the air pump is communicated with the top of the cyclone separator, and the other end of the air pump is fixedly communicated with a second conduit which penetrates through the fixed shell; The outer end of the movable tube is fixedly communicated with a vertical tube, the vertical tube is communicated with the sampling tube through a driving assembly, and the tail end of the sampling tube is fixedly communicated with a plurality of uniformly distributed short air inlet tubes; The servo motor is fixedly arranged on one side of the fixed shell, and a transmission shaft of the servo motor penetrates through the fixed shell and is fixedly connected with the movable pipe. Specifically, offer the mounting hole with the fixed shell adaptation on the buggy pipe, then install the fixed shell on the buggy pipe, when needs sample, start servo motor drives movable tube and rotates, thereby make the sampling tube transversely put on the buggy pipe cross-section, then utilize drive assembly to drive the sampling tube and rotate, and the aspiration pump forms the negative pressure, thereby make the sampling tube can utilize the nozzle stub that admits air to take out the buggy and get into cyclone, then separate the buggy through cyclone, thereby buggy can get into the sample bottle in to be collected, when need not the sample, drive movable tube through servo motor and rotate, thereby can accomodate movable tube, drive assembly and sampling tube into the fixed shell. Preferably, the driving assembly includes: The fixed box is fixedly connected with the vertical pipe, the vertical pipe penetrates through the top of the fixed box and is communicated with a rotating pipe through a second rotary joint, the outer wall of the rotating pipe is fixedly connected with a plurality of uniformly distributed blades, and the rotating pipe movably penetrates through the fixed box and is fixedly communicated with the sampling pipe; one end of the hose is communicated with one side wall of the fixed box, and the other end of the hose is communicated with the second guide pipe; The air outlet is formed in one side of the top of the fixed box, and the inner cavity of the air outlet is fixed with a dustproof screen plate. Specifically, clean gas separated through the cyclone separator can be led into the hose and then enter the inner cavity of the fixed box, so that the clean gas is impacted on the surface of the blade, the blade is rotated, the rotating tube can be driven to rotate, the sampling tube is indirectly driven to rotate, a power source is not required to be additionally arranged for driving, energy conservation is facilitated, the dust screen is arranged, and coal dust is prevented from invading the fixed box when sampling is not needed. Preferably, the inner cavity of the fixed shell is provided with a plugging plate, t
