The invention discloses equipment and a method for detecting the strength of an annular section of a large-diameter TA31 pipe, and relates to the technical field of pipes. According to the annular section strength detection equipment for the large-diameter TA31 pipe, through the design of a composite mechanism, the pipe is placed in the processing mechanism, the pipe space is restrained through the limiting mechanism, the pipe is prevented from moving in the inspection process, danger to workers is avoided, and therefore normal operation of the equipment is kept; the fixing mechanism controls the pipe to rotate and rub with the processing mechanism, so that the effect of cleaning the surface of the pipe is achieved, the situation that stains on the surface of the pipe affect the detection effect is avoided, a hydraulic rod controls a pressing plate to extrude the surface of the pipe, and the detection effect on the annular section strength of the pipe is achieved; therefore, the friction force on the surface of the pipe is increased, the pipe is prevented from shaking in the downward pressing process, and the operation stability is improved.

This invention relates to an adsorption tower and a gas nano-purifier. The adsorption tower includes an outer tube and an inner tube coaxially arranged within the outer tube. The outer tube has a first outlet on its wall. The inner tube includes an inlet section, an adsorption section, and a dust removal section connected sequentially from bottom to top. The inlet section has an inlet on its wall. The adsorption section is filled with adsorbent, and a first filter and a second filter are respectively provided at the connection points between the adsorption section and the inlet and dust removal sections. At least a portion of the sidewalls of the dust removal section is configured as a filter layer. Under purification conditions, the high-pressure gas to be treated enters the inner tube through the inlet, passes sequentially upwards through the adsorption and dust removal sections, enters the annular gap between the inner and outer tubes via the filter layer, and is discharged from the first outlet. Through this configuration, using a tube-in-tube structure with the outer and inner tubes coaxially arranged, the integration of the equipment is improved and its volume is reduced, achieving multi-stage purification of gas within a single component, including diffusion, deep adsorption, and precision dust removal.

The utility model discloses an integrated automatic filtering device which comprises a device body, sliding rings are arranged in the device body, an annular filter screen is arranged between the two sets of sliding rings, a driving frame is fixed in the annular filter screen, a driving motor is installed at the end of the driving frame through a coupler, and the driving motor is connected with the driving frame. And the driving motor is mounted on the upper surface of the device body through a mounting seat. According to the utility model, after sewage is filtered for a long time, the driving motor and the booster pump are started, the driving motor drives the annular filter screen to rotate through the driving frame, and the blowback pipe rotates in a direction opposite to that of the annular filter screen under the action of the first gear and the second gear, so that the blowback nozzle of the blowback pipe is enabled to face filter holes of the annular filter screen; the booster pump pumps outside water to the back-blowing pipe, the back-blowing nozzle is used for back-blowing the filter holes, and meanwhile, the cleaning brush is matched, so that the cleaning effect on the annular filter screen is greatly improved, and flocculent impurities are prevented from penetrating through the filter holes to influence the quality of purified water.

The invention discloses an AQI detection and analysis device for atmospheric pollutants, and relates to the technical field of atmospheric pollutant detectors, and the technical scheme is that the AQI detection and analysis device comprises a detection device, the detection device can detect and analyze air, four supporting legs are arranged at the bottom of the detection device, a handle is arranged at the upper end of the detection device, and a sample feeding pipe is fixedly connected to the upper end of the detection device; according to the invention, during sampling detection, the sampling mechanism extends out, the sealing ring arranged at the upper part of the sampling mechanism can ensure the leakproofness of the sampling shell, and after sampling is completed, the cleaning mechanism can drive the annular brush to rotate so as to effectively clean impurities attached to the inner wall of the sampling shell; the cleaning mechanism can be driven by the transmission mechanism to move in the sampling shell, so that the cleaning range is effectively enlarged, and the turbofan can be rotated reversely to blow air during cleaning, so that brushed dust and impurities can be directly blown out through the sampling hole, and the self-cleaning effect of the equipment is improved.

The utility model discloses a continuous inoculation machine for preparing an antibacterial peptide feed additive through solid state fermentation, and belongs to the technical field of feed additive processing inoculation machine equipment. The device comprises a shell, the interior of the shell is movably connected with a roller, a transmission roller and a spiral conveying rod, the bottom of the roller is connected with the top of the transmission roller, and the spiral conveying rod is located in the roller. The first motor extends into the shell and is fixedly connected with the left side of the transmission roller. According to the utility model, the water distribution row and the atomization nozzle are arranged to spray bacterial liquid into the roller, the roller is driven to rotate by the motor I and the transmission roller to stir solid-state fermentation materials, so that the bacterial liquid can be uniformly inoculated on the solid-state fermentation materials, and cleaning liquid is sprayed to the inner wall of the roller through the spraying pipe; and residues attached to the inner wall of the roller are cleaned by using the cleaning brush, so that the self-cleaning effect of the continuous inoculation machine is improved.
