The hollow suction pipe shaft is arranged as a three-layer stepped shaft, which is convenient for sewage suction. The driving mechanism comprises a motor module and a motor gear, etc., and is responsible for providing power for cleaning. The water suction module comprises a water suction impeller, etc., and cooperates with the hollow suction pipe shaft to form a suction channel and recycle sewage.

The utility model belongs to the technical field of cultural relic surface scanning, particularly relates to a cultural relic surface feature extraction and recognition device, and aims to solve the problem that the surface of a placement platform, used for placing cultural relics, of an existing traditional cultural relic surface feature extraction and recognition device does not have a cleaning function. The top of the base is fixedly connected with a supporting rod, the outer wall of the supporting rod is slidably connected with a sliding block, the driving assembly drives the cleaning assembly to move, the two roller brushes are used for cleaning the top surface of the base and the top surface of the containing disc, and the accuracy of cultural relic surface feature extraction and recognition is improved; the telescopic hose sucks air and exhausts air while the movable frame moves through the inflating assembly, then air is blown to the surface of the top of the base through the multiple air outlet nozzles, large dust is further blown away, the cleaning effect is enhanced, an additional power source is not needed, and the energy-saving performance and practicability of the device are improved.

The utility model discloses a kind of axial flow centrifugal compressor for compressed air energy storage, it is related to energy storage technical field, comprising: axial flow section, centrifugal section and main shaft;The axial flow section has casing and the axial flow rotor in the casing, the centrifugal section has volute and the centrifugal rotor in the volute, the casing is connected with the volute;The axial flow rotor is connected with the one end of the main shaft by fastener, the centrifugal rotor is sleeved on the main shaft, the upstream end of the centrifugal rotor is supported on the boss of the main shaft the downstream end of the centrifugal rotor is detachably connected with the main shaft by connecting structure.The utility model technical scheme, axial flow rotor and centrifugal rotor are respectively set as detachably connected with main shaft, so that axial flow rotor, centrifugal rotor and main shaft can be separately produced, for large flow, high pressure ratio compressor, independent production facilitates each part manufacturing.

The utility model relates to the technical field of refractory brick waste collection, and discloses a steel casting refractory brick waste collection device which comprises a box body, an inner box is fixedly connected to the interior of the box body, a multi-stage screening assembly is installed in the box body and comprises a screening drum and a screening plate, one side of the screening drum is fixedly connected to one side of the outer wall of a conveying box, and the screening plate is fixedly connected to the other side of the outer wall of the conveying box. A conveying box is arranged in the inner box, auger blades are rotationally connected to the interior of the conveying box, the outer walls of the auger blades are rotationally connected to the inner wall of a screen drum, a material guiding pipe is fixedly connected to the outer wall of the screen drum, a first material collecting box is arranged at one end of the material guiding pipe, and a material guiding plate is fixedly connected to the inner wall of the inner box. Waste is smashed through the smashing roller, after the smashed waste falls into the conveying box, the effect that the waste is conveyed into the screen drum to be preliminarily screened is achieved through rotation of auger blades at the moment, the screened waste falls into the grinding roller, and the waste which does not pass through the screen drum falls into the first material collecting box through a material guiding pipe.

A cyclohexanone dehydration and hydrogenation device relates to the technical field of reaction devices and comprises a reaction kettle, the reaction kettle is rotatably provided with a vertically arranged hydrogen inlet pipe, a plurality of stirring plates are arranged on the peripheral wall of the hydrogen inlet pipe from top to bottom in parallel, a cavity is formed in the lowest stirring plate and communicated with the hydrogen inlet pipe, and the hydrogen inlet pipe is communicated with the cavity.
