The application discloses a broaching cutter with a self-repairing function for a tool face, comprising a support and a broach main body fixed on the support, a plurality of containing holes are distributed on the broach main body, and a chip removal and repair unit is arranged in each containing hole; the chip removal and repair unit comprises a brushing assembly and a driving assembly, the brushing assembly comprises a chip removal push rod in sliding cooperation with the containing hole, a chip breaking brush head is connected to the top end of the chip removal push rod, brush hairs are distributed on the side of the chip breaking brush head facing a tool face, a capillary flow channel is arranged in the chip removal push rod, the capillary flow channel is in communication with the brush hairs, the chip breaking brush head can cut off the corresponding position of a chip when the chip breaking brush head is extended out of the containing hole, and the brush hairs can be in contact with the tool face of the corresponding position of a tool tooth. Meanwhile, a broaching method is also disclosed. In the broaching process, the chip breaking brush head reciprocally slides along the tool face of a broach tool tooth to break the chip, and meanwhile, the chip breaking brush head can also apply a surface repair liquid to the tool face of the tool tooth, so that the broach tool is maintained.

This invention provides a pre-gas filtration device for a vacuum pump, belonging to the field of filtration and separation technology. The invention includes a vacuum pump body, a filtration mechanism, a differential pressure sensing mechanism, and a dust removal mechanism disposed on the inlet side of the vacuum pump body. The filtration mechanism includes an inlet housing, a filter housing, and a rear housing. The inlet housing contains an inlet port, guide vanes, baffles, and a storage tank. The filter housing contains multiple layers of filter components. The dust removal mechanism uses a motor to drive a lead screw to rotate, causing a magnetic scraper to move axially along the filter element and clean its outer surface. A magnetic ring simultaneously drives brushes to clean the outer surface of the inner filter cartridge. A dust collection groove on the magnetic ring collects brushed-off dust and can assist in loosening the dust through vibration when the end contacts the brush. The guide vanes also drive a spiral blade inside a hollow rod to rotate via a connecting rod, pushing residual impurities in the central channel to the dust discharge channel. This invention reduces the risk of vacuum pump inlet contamination and filter component clogging, and improves the self-cleaning capability of the filtration device.

The utility model belongs to the technical field of chemical equipment, and discloses an improved chemical small-scale test stirring device. The improved chemical small-scale test stirring device comprises a stirring mechanism and a reaction container, the stirring mechanism is detachably installed on the reaction container, raw materials to be stirred can be contained in the reaction container, and the stirring mechanism can stir the raw materials to be stirred in the reaction container. According to the utility model, through the modularized design, the rapid installation and disassembly can be realized, the operation can be completed by only one person, the disadvantage that the cooperation of multiple persons is needed in the prior art is solved, and the experiment efficiency is greatly improved. Through modular arrangement, all parts in the device can be replaced and cleaned in time, and the influence of residual substances on the device on subsequent experiments is avoided.

The present application belongs to the technical field of cleaning vehicles, and specifically provides a cleaning vehicle with intelligent cleaning and disinfecting functions, which aims to solve the problems of untimely cleaning and disinfecting of mops and wiping materials matched with the cleaning vehicle and poor cleaning management. The present application comprises a mop, a wiping material, a cleaning vehicle and an RFID reader. The mop and the wiping material are provided with RFID tags, and the RFID reader identifies and reads the RFID tags. The cleaning vehicle is provided with a mop cleaning device, a wiping material cleaning device, a clean water tank, a disinfectant container and a water pumping assembly. The water pumping assembly is used for pumping disinfectant in the disinfectant container into the mop cleaning cavity and / or the wiping material cleaning cavity. The mop cleaning device is used for cleaning and disinfecting the mop cloth, and the wiping material cleaning device is used for cleaning and disinfecting the wiping material. The present application intelligently identifies the mop and the wiping material, timely cleans and disinfects them and monitors the cleaning and disinfecting conditions. The present application not only saves time and effort, but also realizes intelligent management of the cleaning and disinfecting of the mop and the wiping material.

The invention belongs to the technical field of intelligent sensors, and particularly relates to a precession flow meter which comprises a base, a flow meter body and a PLC are arranged above the base, the two ends of the flow meter body are connected with a first pipe and a second pipe respectively, the first pipe and the second pipe are each provided with an on-off valve, and the precession flow meter further comprises two clamping and fixing assemblies. The clamping and fixing assembly is fixed to the base and arranged on the outer side of the flow meter body and provides clamping and fixing force for the flow meter body. The precession flowmeter can be cleaned on line without disassembly and assembly, measurement errors caused by disassembly and assembly secondary damage and inner wall scaling are avoided, meanwhile, self-adaptive adjustment of clamping force along with flux is achieved, high-speed vibration is prevented, signal interference intensification caused by too high rigidity is avoided, the installation stability and the measurement precision are improved, and the measurement precision is improved. Flux can be automatically metered, online cleaning is triggered at a threshold value, cleaning is conducted in time, and impurity blockage is prevented from affecting measurement accuracy.
